SAN DIEGO — Low fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs) dietary advice has been shown to be effective in easing bloating and abdominal pain, especially in patients with irritable bowel syndrome (IBS), but limited availability of dietitians makes delivering this advice challenging. Researchers from Thailand have successfully enlisted a chatbot to help.

In a randomized controlled trial, they found that chatbot-assisted dietary advice with brief guidance effectively reduced high FODMAP intake, bloating severity, and improved dietary knowledge, particularly in patients with bothersome bloating.

“Chatbot-assisted dietary advice for FODMAPs restriction was feasible and applicable in patients with bloating symptoms that had baseline symptoms of moderate severity,” study chief Pochara Somvanapanich, with the Division of Gastroenterology, Chulalongkorn University and King Chulalongkorn Memorial Hospital, Bangkok, Thailand, told GI & Hepatology News.

Somvanapanich, who developed the chatbot algorithm, presented the study results at Digestive Disease Week (DDW) 2025.

More Knowledge, Less Bloating

The trial enrolled 86 adults with disorders of gut-brain interaction experiencing bloating symptoms for more than 6 months and consuming more than seven high-FODMAPs items per week. Half of them had IBS.

At baseline, gastrointestinal (GI) symptoms and the ability to identify FODMAPs were assessed. All participants received a 5-minute consultation on FODMAPs avoidance from a GI fellow and were randomly allocated (stratified by IBS diagnosis and education) into two groups.

The chatbot-assisted group received real-time dietary advice via a chatbot which helped them identify high, low, and non-FODMAP foods from a list of more than 300 ingredients/dishes of Thai and western cuisines.

The control group received only brief advice on high FODMAPs restriction. Both groups used a diary app to log food intake and postprandial symptoms. Baseline bloating, abdominal pain and global symptoms severity were similar between the two groups. Data on 64 participants (32 in each group) were analyzed.

After 4 weeks, significantly more people in the chatbot group than the control group responded — achieving a 30% or greater reduction in daily worst bloating, abdominal pain or global symptoms (19 [59%] vs 10 [31%], P < .05). Responder rates were similar in the IBS and non-IBS subgroups.

Subgroup analysis revealed significant differences between groups only for participants with bothersome bloating, not those with mild bloating severity.

In those with bothersome bloating severity, the chatbot group had a higher response rate (69.5% vs 36.3%) and fewer bloating symptoms (P < .05). They also had a greater reduction in high FODMAPs intake (10 vs 23 items/week) and demonstrated improved knowledge in identifying FODMAPs (P < .05).

“Responders in a chatbot group consistently engaged more with the app, performing significantly more weekly item searches than nonresponders (P < .05),” the authors noted in their conference abstract.

“Our next step is to develop the chatbot-assisted approach for the reintroduction and personalization phase based on messenger applications (including Facebook Messenger and other messaging platforms),” Somvanapanich told GI & Hepatology News.

“Once we’ve gathered enough data to confirm these are working effectively, we definitely plan to create a one-stop service application for FODMAPs dietary advice,” Somvanapanich added.

Lack of Robust Data on Digital GI Health Apps

Commenting on this research for GI & Hepatology News, Sidhartha R. Sinha, MD, Director of Digital Health and Innovation, Division of Gastroenterology and Hepatology, Stanford University in Stanford, California, noted that there is a “notable lack of robust data supporting digital health tools in gastroenterology. Despite hundreds of apps available, very few are supported by well-designed trials.”

“The study demonstrated that chatbot-assisted dietary advice significantly improved bloating symptoms, reduced intake of high-FODMAP foods, and enhanced patients’ dietary knowledge compared to brief dietary counseling alone, especially in those with bothersome symptoms,” said Sinha, who wasn’t involved in the study.

“Patients actively used the chatbot to manage their symptoms, achieving a higher response rate than those in the control arm who received brief counseling on avoiding high-FODMAP food,” he noted.

Sinha said in his practice at Stanford, “in the heart of Silicon Valley,” patients do use digital resources to manage their GI symptoms, including diseases like IBS and inflammatory bowel disease (IBD) — and he believes this is “increasingly common nationally.”

“However, the need for evidence-based tools is critical and the lack here often prevents many practitioners from regularly recommending them to patients. This study aligns well with clinical practice, and supports the use of this particular app to improve IBS symptoms, particularly when access to dietitians is limited. These results support chatbot-assisted dietary management as a feasible, effective, and scalable approach to patient care,” Sinha told GI & Hepatology News.

The study received no commercial funding. Somvanapanich and Sinha had no relevant disclosures.

SAN DIEGO — A real-time, blood-sensing capsule (PillSense) is a safe and effective diagnostic tool for patients with suspected upper gastrointestinal (GI) bleeding that can aid patient triage, reduce unnecessary procedures, and optimize resource use, a study found.

Notably, patients with negative capsule results had shorter hospital stays and lower acuity markers, and in more than one third of cases, an esophagogastroduodenoscopy (EGD) was avoided altogether without any observed adverse events or readmissions, the study team found.

“Our study shows that this novel capsule that detects blood in the upper GI tract (PillSense) was highly sensitive and specific (> 90%) for detecting recent or active upper GI blood, influenced clinical management in 80% of cases and allowed about one third of patients to be safely discharged from the emergency department, with close outpatient follow-up,” Linda Lee, MD, AGAF, medical director of endoscopy, Brigham and Women’s Hospital and associate professor of medicine, Harvard Medical School, Boston, told GI & Hepatology News.

The study was presented at Digestive Disease Week^® (DDW) 2025.

 

Real-World Insights

EGD is the gold standard for diagnosing suspected upper GI bleeding, but limited access to timely EGD complicates diagnosis and resource allocation.

Approved by the US Food and Drug Administration, PillSense (EnteraSense) is an ingestible capsule with a reusable receiver that provides a rapid, noninvasive method for detecting upper GI bleeding. The capsule analyzes light absorption to identify blood and transmits the result within 10 minutes.

Lee and colleagues evaluated the real-world impact of this point-of-care device on clinical triage and resource allocation, while assessing its safety profile.

They analyzed data on 43 patients (mean age 60 years; 72% men) with clinical suspicion of upper GI bleeding in whom the device was used. The most common symptoms were symptomatic anemia (70%), melena (67%), and hematemesis (33%).

Sixteen PillSense studies (37%) were positive for blood detection, and 27 (63%) were negative.

Compared to patients with a positive capsule results, those without blood detected by the capsule had shorter hospital stays (mean, 3.8 vs 13.4 days, P = .02), lower GBS scores (mean, 7.93 vs 12.81; P = .005), and fewer units of blood transfused (mean, 1.19 vs 10.94; P = .01) and were less apt to be hemodynamically unstable (5 vs 8 patients; P = .03).

Capsule results influenced clinical management in 80% of cases, leading to avoidance of EGD in 37% and prioritization of urgent EGD in 18% (all had active bleeding on EGD).

Capsule use improved resource allocation in 51% of cases. This included 12 patients who were discharged from the ED, six who were assigned an inpatient bed early, and four who underwent expedited colonoscopy as upper GI bleeding was ruled out, they noted.

Among the eight patients who did not undergo EGD, there were no readmissions within 30 days and no adverse events. There were no capsule-related adverse events.

“Clinicians should consider using this novel capsule PillSense as another data point in the management of suspected upper GI bleed,” Lee told GI & Hepatology News.

“This could include in helping to triage patients for safe discharge from the ED or to more urgent endoscopy, to differentiate between upper vs lower GI bleed and to manage ICU patients with possible rebleeding,” Lee said.

 

Important Real-World Evidence

Reached for comment, Shahin Ayazi, MD, esophageal surgeon, Director, Allegheny Health Network Chevalier Jackson Esophageal Research Center, Pittsburgh, Pennsylvania, said this study is important for several reasons.

“Prior investigations have established that PillSense possesses a high negative predictive value for detecting upper GI bleeding and have speculated on its utility in triage, decision-making, and potentially avoiding unnecessary endoscopy. This study is important because it substantiates that speculation with clinical data,” Ayazi, who wasn’t involved in the study, told GI & Hepatology News.

“These findings support the capsule’s practical application in patient stratification and clinical workflow, particularly when diagnostic uncertainty is high and endoscopic resources are limited,” Ayazi noted.

In his experience, PillSense is “highly useful as a triage adjunct in the evaluation of suspected upper GI bleeding. It provides direct and objective evidence as to whether blood is currently present in the stomach,” he said.

“In patients whose presentation is ambiguous or whose clinical scores fall into an intermediate risk zone, this binary result can provide clarity that subjective assessment alone may not achieve. This is particularly relevant in settings where the goal is to perform endoscopy within 24 hours, but the volume of consults exceeds procedural capacity,” Ayazi explained.

“In such scenarios, PillSense enables physicians to stratify patients based on objective evidence of active bleeding, helping to prioritize those who require urgent endoscopy and defer or even avoid endoscopic evaluation in those who do not. The result is a more efficient allocation of endoscopic resources without compromising patient safety,” he added.

Ayazi cautioned that the PillSense capsule should not be used as a replacement for clinical evaluation or established risk stratification protocols.

“It is intended for hemodynamically stable patients and has not been validated in cases of active or massive bleeding. Its diagnostic yield depends on the presence of blood in the stomach at the time of capsule transit; intermittent or proximal bleeding that has ceased may not be detected, introducing the potential for false-negative results,” Ayazi told GI & Hepatology News.

“However, in prior studies, the negative predictive value was high, and in the present study, no adverse outcomes were observed in patients who did not undergo endoscopy following a negative PillSense result,” Ayazi noted.

“It must also be understood that PillSense does not localize the source of bleeding or replace endoscopy in patients with a high likelihood of active hemorrhage. It is not designed to detect bleeding from the lower GI tract or distal small bowel. Rather, it serves as an adjunct that can provide immediate clarity when the need for endoscopy is uncertain, and should be interpreted within the broader context of clinical findings, laboratory data, and established risk stratification tools,” he added.

The study had no specific funding. Lee and Ayazi had no relevant disclosures.

SAN DIEGO – Advanced practice providers (APPs) can be trained to perform transnasal endoscopy (TNE) with a single-use ultra-slim gastroscope with only topical anesthesia, a pilot study showed.

“Our study showed that TNE can be performed safely by APPs, is well tolerated by patients, and significantly impacted patient management,” Whitney Kucher, PA-C, with Northwestern Medicine, Chicago, told GI & Hepatology News.

“The chief benefit of having APPs perform TNEs is increasing patient access and expediting management of upper GI [gastrointestinal] symptoms in patients,” said Kucher who presented the study at Digestive Disease Week® (DDW) 2025.

The EvoEndo single-use endoscopy system received 510(k) clearance from the US Food and Drug Administration in early 2022.

The system includes a sterile, single-use, flexible gastroscope designed for unsedated transnasal upper endoscopy and a small portable video controller.

Unsedated TNE can be used to evaluate and diagnose a wide range of upper GI conditions that may require frequent monitoring, including eosinophilic esophagitis (EoE), dysphagia, celiac disease, gastroesophageal reflux disease (GERD), Barrett’s esophagus (BE), malabsorption, and abdominal pain.

Kucher and colleagues assessed the ability for APPs to use the EvoEndo system to perform safe and accurate esophageal assessment using in-office TNE, following training.

TNE training lasted about 4 weeks and consisted of a stepwise approach involving lectures, simulation-based training, and hands-on supervised TNEs (10 per APP).

Once training was completed, and after providing consent, 25 patients were enrolled to undergo supervised TNE by an APP. Their mean age was 55 years, and 58% were women.

Indications for TNE were uncontrolled GERD symptoms in 12 patients, history of EoE in six patients, high-risk screening for BE in five patients, and dysphagia in two patients.

Technical success was achieved in all but one patient (96%), and there were no adverse events.

All 25 patients completed the procedure, with 17 (72%) giving it a TNEase score of 1 (with ease/no discomfort) or 2 (mild/occasional discomfort). Only two patients reported a score of 4 (very uncomfortable) but still completed the exam.

The average TNE procedure time was 7.3 minutes.

TNE findings changed management in 23 of 25 (92%) patients. The test led to a change in proton pump inhibitor dosing or interval in 14 patients (56%). Esophagogastroduodenoscopy (EGD) interval was extended in five patients (20%) and scheduled sooner in three patients (12%). Two patients (8%) had no change in management.

The study team said more data are needed in terms of learning curves, competency metrics, and health economics before widespread adoption can be supported.

“We are working on developing a standardized training plan so we can train more GI APPs in our department. We have plans to start an APP-driven TNE program in the coming months,” Kucher told GI & Hepatology News.

 

Caveats and Cautionary Notes

Commenting on this study for GI & Hepatology News, Amitabh Chak, MD, professor of medicine and oncology at Case Western Reserve University School of Medicine and University Hospitals Cleveland Medical Center, both in Cleveland, noted that the results are “similar to older studies where TNE appeared quite promising and APPs could be trained. There have been previous studies that APPs can perform colonoscopies and EGDs.”

Chak cautioned that previous studies showed that it took at least 50 supervised examinations for APPs to achieve the needed skills.

“Intubation transnasally can be painful for patients if not done with skill. Cognitive skills take longer. The gastroesophageal junction is dynamic, and recognition of subtle pathology takes training,” Chak noted.

“TNE has been around at least two decades. The challenge with uptake of TNE for Barrett’s screening has been acceptance by primary care physicians, patients and payers,” Chak told GI & Hepatology News.

The study had no specific funding. Kucher reported having no relevant disclosures. Chak reported having relationships with US Endoscopy, Lucid Diagnostics, Steris Endoscopy/US Endoscopy, Microtek, and Interpace Diagnostics.

SAN DIEGO – Advanced practice providers (APPs) can be trained to perform transnasal endoscopy (TNE) with a single-use ultra-slim gastroscope with only topical anesthesia, a pilot study showed.

“Our study showed that TNE can be performed safely by APPs, is well tolerated by patients, and significantly impacted patient management,” Whitney Kucher, PA-C, with Northwestern Medicine, Chicago, told GI & Hepatology News.

“The chief benefit of having APPs perform TNEs is increasing patient access and expediting management of upper GI [gastrointestinal] symptoms in patients,” said Kucher who presented the study at Digestive Disease Week® (DDW) 2025.

The EvoEndo single-use endoscopy system received 510(k) clearance from the US Food and Drug Administration in early 2022.

The system includes a sterile, single-use, flexible gastroscope designed for unsedated transnasal upper endoscopy and a small portable video controller.

Unsedated TNE can be used to evaluate and diagnose a wide range of upper GI conditions that may require frequent monitoring, including eosinophilic esophagitis (EoE), dysphagia, celiac disease, gastroesophageal reflux disease (GERD), Barrett’s esophagus (BE), malabsorption, and abdominal pain.

Kucher and colleagues assessed the ability for APPs to use the EvoEndo system to perform safe and accurate esophageal assessment using in-office TNE, following training.

TNE training lasted about 4 weeks and consisted of a stepwise approach involving lectures, simulation-based training, and hands-on supervised TNEs (10 per APP).

Once training was completed, and after providing consent, 25 patients were enrolled to undergo supervised TNE by an APP. Their mean age was 55 years, and 58% were women.

SAN DIEGO — An artificial intelligence (AI)–enhanced digital collaborative care model led to rapid, clinically significant, and sustained symptom relief for patients with irritable bowel syndrome (IBS) seen at Cleveland Clinic, Cleveland, Ohio, an observational study found.

Symptom tracking at 4-week intervals showed that “almost everybody got better” regardless of IBS subtype, with relief starting in the first 4 weeks, Stephen Lupe, PsyD, gastrointestinal psychologist and director of Behavioral Medicine, Department of Gastroenterology, Hepatology, and Nutrition at Cleveland Clinic, Cleveland, said in an interview with GI & Hepatology News.

The findings were presented at Digestive Disease Week (DDW) 2025.

 

Digital Boost to Collaborative Care Model

The combination of dietary interventions and brain-gut behavioral therapy has demonstrated excellent outcomes for patients with IBS, but patients struggle to access these needed services, Lupe noted. A medical home collaborative care model in which patients get care from a multidisciplinary team has been shown to be a good way to successfully deliver this combination of care.

“When you do collaborative in-person care, people get better quicker,” Lupe said.

However, scaling access to this model remains a challenge. For their study, Cleveland Clinic researchers added an AI-enhanced digital platform, Ayble Health, to the in-person collaborative care model to expand access to disease-management services and evaluated whether it improved clinical outcomes for study’s 171 participants, who were recruited via social media advertisements.

Here’s how the platform works. Once a patient enrolls in Ayble Health, a personalized care plan is recommended based on a virtual visit, screening questionnaire, and baseline survey.

The platform includes brain-gut programs, including guided audio content on mindfulness, hypnosis, meditation, cognitive behavioral therapy, and breathing techniques; personalized nutrition support to find and remove trigger foods, a food barcode scanner, and a comprehensive groceries database; and AI-powered wellness tools to help manage and track symptoms. Lupe worked with Ayble Health to develop the platform’s behavioral health content and care pathways.

Patients may choose to follow any combination of three care pathways: A care team overseen by gastro-psychologists, dietitians, and gastroenterologists; a holistic nutrition program including a personalized elimination diet; and a brain-gut behavioral therapy program with gut-directed hypnosis, cognitive behavioral therapy, and acceptance and commitment therapy. They go at their own pace, can connect with Ayble Health’s virtual care team to help with education and goal setting, and continue to consult their Cleveland Clinic providers as needed for evaluation and treatment.

“The care team is still there. We’ve just augmented it to make sure that as many people as possible get behavioral skills training and dietary support, with monitoring between visits — instead of the traditional, ‘I’ll see you in 6 months approach,” Lupe explained.

 

IBS Symptom Scores Improve

Of the study’s 171 patients, 20 had IBS-diarrhea, 23 had IBS-constipation, 32 had IBS-mixed, and 8 had IBS-unspecified. The remaining 88 patients reported IBS without indication of subtype.

At intake, all patients had active IBS symptoms, with scores ≥ 75 on the IBS symptom severity scale (IBS-SSS). Most patients enrolled in more than one care pathway, and 95% of participants completed at least 4 weeks on their chosen pathways.

Overall, patients saw an average 140-point decrease in IBS-SSS from intake through follow-up lasting up to 42 weeks. A drop in IBS-SSS score ≥ 50 points was considered a clinically meaningful change.

Symptom improvements occurred as early as week 4, were sustained and were uniform across IBS subtypes, suggesting that the AI-enhanced digital collaborative care model has wide utility in patients with IBS, Lupe said.

Patients with the most severe IBS symptoms showed the greatest improvement, but even 50% of those with mild symptoms had clinically meaningful changes in IBS-SSS.

Improvement in IBS symptoms was seen across all care pathways, but the combination of multiple pathways improved outcomes better than a single care pathway alone. The combination of nutrition and brain-gut behavioral therapy demonstrated the greatest reduction in IBS-SSS scores and proportion of patients achieving clinically meaningful results (95%).

The digital comprehensive car model for IBS is now “up and running” at Cleveland Clinic, and the team plans to proactively reach out to patients with gastrointestinal disorders recently seen at their center to alert them to the availability of this tool, Lupe said.

A randomized controlled trial is planned to further validate these observational findings, he added.

 

‘Wave of the Future’

The digital collaborative care model is “innovative, and I think is the wave of the future,” Kyle Staller, MD, MPH, gastroenterologist and director of the Gastrointestinal Motility Laboratory at Massachusetts General Hospital, Boston, who wasn’t involved in the study, told GI & Hepatology News.

“These digital platforms bundle nondrug options, such as cognitive-behavioral therapy, dietary therapy, hypnotherapy, so patients can choose what suits them, rather than the gastroenterologist hunting down each individual resource, which requires a lot of work,” Staller said.

The study “provides real-world evidence that a deliberative, digital, collaborative care model that houses various types of nondrug IBS treatment under one roof can provide meaningful benefit to patients,” Staller told GI & Hepatology News.

Importantly, he said, “patients chose which option they wanted. At the end of the day, the way that we should be thinking about IBS care is really making sure that we engage the patient with treatment choices,” Staller said.

This study had no specific funding. Three authors had relationships with Ayble Health. Lupe is a scientific advisor for Boomerang Health and paid lecturer for Takeda Pharmaceuticals. Staller disclosed having relationships with Mahana Therapeutics, Ardelyx Inc, Gemelli Biotech, Salix Pharmaceuticals, and Takeda Pharmaceuticals.

SAN DIEGO — A 20-year initiative by Kaiser Permanente Northern California that assessed colorectal cancer (CRC) screening status and offered flexible options for screening has made a huge difference in CRC incidence, deaths, and racial disparities, an analysis showed.

“The program promptly doubled the proportion of people up to date with screening,” reported lead investigator Douglas A. Corley, MD, PhD, AGAF, a research scientist with Kaiser’s Division of Research, at a press briefing held on April 24, ahead of a presentation at the Digestive Disease Week® (DDW) 2025.

Additionally, within about 10 years, cancer rates were cut by a third, deaths were halved for the second most common cause of cancer deaths in the United States, and the differences that had previously been seen by race or ethnicity were largely eliminated, he said.

“Ten years ago, there were big gaps in cancer risk and death, especially among our Black patients. Now, those differences are nearly gone,” Corley said.

 

Closing the Gap

A systematic CRC screening program was implemented across Kaiser Permanente Northern California. The program included proactive outreach to members who were overdue for screening and mailing them fecal immunochemical test (FIT) kits for at-home use.

Corley and colleagues tracked screening status and CRC incidence and mortality annually from 2000 to 2019 among about 1.1 million members aged 50-75 years across 22 medical centers of the integrated healthcare system. The cohort included American Indian or Alaska Native, Asian, Black, Hispanic, Native Hawaiian or Pacific Islander, and White members.

Screening rates via FIT, colonoscopy, or sigmoidoscopy more than doubled after starting the program, from about 37% in the early years to about 80% within a few years, and it stayed that high through 2019, Corley reported. 

“Importantly, these large increases occurred across the whole population with only small differences,” he said. 

For example, about 76% of Hispanic members, 77% of Black members, 82% of White members, and 83% of Asian members were up to date in the later years and through 2019.

“This shows that systematic, comparable outreach can provide a level playing field for completion of preventive care,” Corley said.

After an expected early uptick in CRC incidence due to early detection, incidence later declined and by 2019 had dropped approximately 30% across the groups.

 

Long-Standing Disparities Erased

CRC deaths also fell by about 50% across all groups, with the largest decline among Black members, Corley noted.

Racial and ethnic disparities in both CRC incidence and mortality have long existed, with Black patients in particular experiencing higher risks and worse outcomes, likely from a mixture of risk factors and healthcare utilization, Corley said.

Offering outreach and equal access to screening in the Kaiser program erased those long-standing disparities.

“It’s remarkable that some of these large differences in mortality by race and ethnicity that we saw two decades ago, and which are found throughout the United States, are now similar to small chance variation in the population,” Corley said.

Flexibility was key to getting more people screened, he noted. “It’s about reaching people at their homes and offering a choice to patients. It’s an astonishingly simple concept.”

It’s important to note that these findings stem from a large, integrated healthcare system, which may differ from other settings, although similar outreach strategies have succeeded in safety net clinics and smaller practices, Corley added.

By boosting screening rates to 80%, the health system reached the level that’s essentially been defined in the past as our goal of screening programs, said Loren Laine, MD, AGAF, professor of medicine (digestive diseases) at Yale School of Medicine, New Haven, Connecticut, and chair of this year’s DDW. 

“It shows that if health systems institute programmatic screening for all their covered individuals, they could markedly increase screening, said Laine, who also served as moderator of the press briefing.

“Most importantly, of course, [screening] was associated with a reduction in colorectal cancer incidence and deaths,” he said.

The study had no commercial funding. Corley reported having no relevant conflicts of interest.

Laine’s disclosures included consulting and/or relationships with Medtronic, Phathom Pharmaceuticals, Biohaven, Celgene, Intercept, Merck, and Pfizer.

After an expected early uptick in CRC incidence due to early detection, incidence later declined and by 2019 had dropped approximately 30% across the groups.

 

Long-Standing Disparities Erased

CRC deaths also fell by about 50% across all groups, with the largest decline among Black members, Corley noted.

Racial and ethnic disparities in both CRC incidence and mortality have long existed, with Black patients in particular experiencing higher risks and worse outcomes, likely from a mixture of risk factors and healthcare utilization, Corley said.

Offering outreach and equal access to screening in the Kaiser program erased those long-standing disparities.

“It’s remarkable that some of these large differences in mortality by race and ethnicity that we saw two decades ago, and which are found throughout the United States, are now similar to small chance variation in the population,” Corley said.

Flexibility was key to getting more people screened, he noted. “It’s about reaching people at their homes and offering a choice to patients. It’s an astonishingly simple concept.”

It’s important to note that these findings stem from a large, integrated healthcare system, which may differ from other settings, although similar outreach strategies have succeeded in safety net clinics and smaller practices, Corley added.

By boosting screening rates to 80%, the health system reached the level that’s essentially been defined in the past as our goal of screening programs, said Loren Laine, MD, AGAF, professor of medicine (digestive diseases) at Yale School of Medicine, New Haven, Connecticut, and chair of this year’s DDW. 

“It shows that if health systems institute programmatic screening for all their covered individuals, they could markedly increase screening, said Laine, who also served as moderator of the press briefing.

“Most importantly, of course, [screening] was associated with a reduction in colorectal cancer incidence and deaths,” he said.

The study had no commercial funding. Corley reported having no relevant conflicts of interest.

Laine’s disclosures included consulting and/or relationships with Medtronic, Phathom Pharmaceuticals, Biohaven, Celgene, Intercept, Merck, and Pfizer.

SAN DIEGO — A 20-year initiative by Kaiser Permanente Northern California that assessed colorectal cancer (CRC) screening status and offered flexible options for screening has made a huge difference in CRC incidence, deaths, and racial disparities, an analysis showed.

“The program promptly doubled the proportion of people up to date with screening,” reported lead investigator Douglas A. Corley, MD, PhD, AGAF, a research scientist with Kaiser’s Division of Research, at a press briefing held on April 24, ahead of a presentation at the Digestive Disease Week® (DDW) 2025.

Additionally, within about 10 years, cancer rates were cut by a third, deaths were halved for the second most common cause of cancer deaths in the United States, and the differences that had previously been seen by race or ethnicity were largely eliminated, he said.

“Ten years ago, there were big gaps in cancer risk and death, especially among our Black patients. Now, those differences are nearly gone,” Corley said.

 

Closing the Gap

A systematic CRC screening program was implemented across Kaiser Permanente Northern California. The program included proactive outreach to members who were overdue for screening and mailing them fecal immunochemical test (FIT) kits for at-home use.

Corley and colleagues tracked screening status and CRC incidence and mortality annually from 2000 to 2019 among about 1.1 million members aged 50-75 years across 22 medical centers of the integrated healthcare system. The cohort included American Indian or Alaska Native, Asian, Black, Hispanic, Native Hawaiian or Pacific Islander, and White members.

Screening rates via FIT, colonoscopy, or sigmoidoscopy more than doubled after starting the program, from about 37% in the early years to about 80% within a few years, and it stayed that high through 2019, Corley reported. 

“Importantly, these large increases occurred across the whole population with only small differences,” he said. 

For example, about 76% of Hispanic members, 77% of Black members, 82% of White members, and 83% of Asian members were up to date in the later years and through 2019.

“This shows that systematic, comparable outreach can provide a level playing field for completion of preventive care,” Corley said.

Both endoscopic ultrasound–guided rendezvous (EUS-RV) and precut sphincterotomy are equally effective salvage techniques for patients with benign biliary obstruction and difficult bile duct cannulation, new data suggest.

Selective deep cannulation of the common bile duct remains the key rate-limiting step in successful endoscopic retrograde cholangiopancreatography (ERCP), especially in benign biliary disease.

In cases of difficult cannulation, the traditional fallback has been precut sphincterotomy. Recently, EUS-RV has emerged as an alternative. However, head-to-head comparisons of these salvage techniques in homogeneous patient populations have been lacking, until now. 

A team led by Arup Choudhury, MD, DM, with Department of Gastroenterology, Postgraduate Institute of Medical Education and Research, Chandigarh, India, compared the two salvage techniques in a single-center, randomized controlled trial of 100 patients with benign biliary disease and difficult bile duct cannulation.

There were 50 patients in each group. When one technique failed, patients were crossed over to the other technique.

The technical success rate for achieving deep biliary, the primary outcome measure, was similar with EUS-RV and precut sphincterotomy (92% and 90%, respectively; P = 1.00; relative risk [RR], 1.02), the authors reported in Annals of Internal Medicine.

Median procedure time was also comparable (10.1 minutes with EUS-RV and 9.75 minutes with precut sphincterotomy). As expected, radiation exposure was notably higher in the EUS-RV group (median, 200.2 vs 67.8 mGy).

There was no difference in overall complication rates (12% and 10%, respectively; RR, 1.20).

Five patients in each group (10%) developed post-ERCP pancreatitis (PEP); one patient in the EUS-RV had moderately severe pancreatitis, whereas the rest had mild pancreatitis.

In an exploratory analysis of the subcohort of 72 patients who did not have 1 or more inadvertent pancreatic duct cannulation, two (5.6%) patients in the precut sphincterotomy group had PEP, whereas none of the patients in the EUS-RV had PEP (RR, 0.21). The investigators caution that a larger, multicenter, randomized controlled trial would be required to evaluate the “probable benefit” of lower PEP in the EUS-RV approach.

None of the patients had bleeding or perforation, but two (4%) patients in the EUS-RV group had an infection after the intervention. One required repeated ERCP due to post procedure cholangitis, whereas the other developed lower respiratory tract infection with transient acute lung injury and sputum showing gram-negative organism. None of the patients required surgical intervention.

“Interestingly,” said the investigators, on crossover from one salvage technique to the other, all of the cases could be successfully cannulated, suggesting the two salvage techniques are “complementary to each other and can help achieve successful cannulation in all cases when used in any sequence.”

Summing up, they said it appears from this head-to-head comparison that both EUS-RV and precut sphincterotomy can be considered effective salvage techniques in expert centers with similar safety and success profiles.

Limitations included the single-center design with both procedures performed by expert operators. EUS-RV entailed additional cost of needle and use of a separate scope, and a cost-efficacy analysis was not done.

This study had no specific funding. Disclosures for the authors are available with the original article.

Researchers have developed and internally validated a simple score using clinical factors that can help estimate the likelihood of advanced colorectal neoplasia in adults younger than age 45 years.

While colorectal cancer (CRC) incidence has declined overall due to screening, early-onset CRC is on the rise, particularly in individuals younger than 45 years — an age group not currently recommended for CRC screening.

Studies have shown that the risk for early-onset advanced neoplasia varies based on several factors, including sex, race, family history of CRC, smoking, alcohol consumption, diabetes, hyperlipidemia, obesity, and diet.

A score that incorporates some of these factors to identify which younger adults are at higher risk for advanced neoplasia, a precursor to CRC, could support earlier, more targeted screening interventions.

The simple clinical score can be easily calculated by primary care providers in the office, Carole Macaron, MD, lead author of the study and a gastroenterologist at Cleveland Clinic, told GI & Hepatology News. “Patients with a high-risk score would be referred for colorectal cancer screening.”

The study was published in Digestive Diseases and Sciences.

To develop and validate their risk score, Macaron and colleagues did a retrospective cross-sectional analysis of 9446 individuals aged 18-44 years (mean age, 36.8 years; 61% women) who underwent colonoscopy at their center.

Advanced neoplasia was defined as a tubular adenoma ≥ 10 mm or any adenoma with villous features or high-grade dysplasia, sessile serrated polyp ≥ 10 mm, sessile serrated polyp with dysplasia, traditional serrated adenoma, or invasive adenocarcinoma.

The 346 (3.7%) individuals found to have advanced neoplasia served as the case group, and the remainder with normal colonoscopy or non-advanced neoplasia served as controls.

A multivariate logistic regression model identified three independent risk factors significantly associated with advanced neoplasia: Higher body mass index (BMI; P = .0157), former and current tobacco use (P = .0009 and P = .0015, respectively), and having a first-degree relative with CRC < 60 years (P < .0001) or other family history of CRC (P = .0117).

The researchers used these risk factors to develop a risk prediction score to estimate the likelihood of detecting advanced neoplasia, which ranged from a risk of 1.8% for patients with a score of 1 to 22.2% for those with a score of 12. Individuals with a score of ≥ 9 had a 14% or higher risk for advanced neoplasia.

Based on the risk model, the likelihood of detecting advanced neoplasia in an asymptomatic 32-year-old overweight individual, with a history of previous tobacco use and a first-degree relative younger than age 60 with CRC would be 20.3%, Macaron and colleagues noted.

The model demonstrated “moderate” discriminatory power in the validation set (C-statistic: 0.645), indicating that it can effectively differentiate between individuals at a higher and lower risk for advanced neoplasia.

Additionally, the authors are exploring ways to improve the discriminatory power of the score, possibly by including additional risk factors.

Given the score is calculated using easily obtainable risk factors for individuals younger than 45 who are at risk for early-onset colorectal neoplasia, it could help guide individualized screening decisions for those in whom screening is not currently offered, Macaron said. It could also serve as a tool for risk communication and shared decision-making.

Integration into electronic health records or online calculators may enhance its accessibility and clinical utility.

The authors noted that this retrospective study was conducted at a single center caring mainly for White non-Hispanic adults, limiting generalizability to the general population and to other races and ethnicities.

 

Validation in Real-World Setting Needed

“There are no currently accepted advanced colorectal neoplasia risk scores that are used in general practice,” said Steven H. Itzkowitz, MD, AGAF, professor of medicine, oncological sciences, and medical education, Icahn School of Medicine at Mount Sinai in New York City. “If these lesions can be predicted, it would enable these young individuals to undergo screening colonoscopy, which could detect and remove these lesions, thereby preventing CRC.”

Many of the known risk factors (family history, high BMI, or smoking) for CRC development at any age are incorporated within this tool, so it should be feasible to collect these data,” said Itzkowitz, who was not involved with the study.

But he cautioned that accurate and adequate family histories are not always performed. Clinicians also may not have considered combining these factors into an actionable risk score.

“If this score can be externally validated in a real-world setting, it could be a useful addition in our efforts to lower CRC rates among young individuals,” Itzkowitz said.

The study did not receive any funding. Macaron and Itzkowitz reported no competing interests.
