Background: While bariatric surgery may reduce obesity-associated inflammation, alterations in gut microbiome and nutrition could impact inflammatory bowel disease (IBD) risk. This study aimed to investigate the association between bariatric surgery and new onset IBD. Methods: A systematic review and meta-analysis of observational studies was conducted from inception to 31 January 2024. Risk estimates were pooled using a DerSimonian and Laird random-effects model, and adjusted hazards ratios (HRs) with corresponding 95% confidence interval (CI) were reported. The modified Newcastle-Ottawa Quality Assessment Scale (NOS) was used to examine the risk of bias. Results: Of 98 articles screened, four studies comprising 4,727,600 participants were included in the systematic review and two studies in the meta-analysis. Included studies had high quality and low risk of bias according to NOS. The pooled analysis revealed a significant risk of new onset IBD (HR: 1.28, 95% CI: 1.04–1.53, I2 = 74.9%), particularly Crohn’s disease (HR: 1.75, 1.59–1.92, I2 = 0), following bariatric surgery, but no significant risk of ulcerative colitis (HR: 0.93, 0.75–1.11, I2 = 11.5%). Conclusions: This meta-analysis found that bariatric surgery was associated with a higher risk of developing Crohn’s disease. Patients should be counseled on IBD risk pre-surgery, and symptomatic patients should be evaluated post-surgery to enable early diagnosis and management.

Purpose of review The aim of this review is to present the current state of the field, highlight recent developments, and describe the clinical outcomes of endoscopic therapies for bariatric surgery complications. Recent findings The field of interventional endoscopy now presents a range of minimally invasive procedures for addressing postbariatric complications. Lumen-opposing metal stents have emerged as a reliable solution for managing gastrojejunal strictures following Roux-en-Y gastric bypass, whether with or without associated leaks. Additionally, they serve as a conduit for performing endoscopic retrograde cholangiopancreatography (ERCP) post-RYGB via EUS-directed ERCP (EDGE). Gastric peroral endoscopic myotomy, originally designed for gastroparesis, has demonstrated effectiveness in treating postgastric sleeve stenosis, particularly the challenging helical stenosis cases. Furthermore, innovative endoscopic antireflux techniques are showing encouraging outcomes in addressing gastroesophageal reflux disease (GERD) following sleeve gastrectomy. Additionally, several modifications have been proposed to enhance the efficacy of transoral outlet reduction (TORe), originally developed to treat weight regain due to gastrojejunal anastomotic issues post-RYGB. Summary Endoscopic management of bariatric surgery complications is continuously evolving. The development of new techniques and devices allows endoscopists to provide novel, minimally invasive alternatives that were not possible in the near past. Many techniques, however, are limited to expert centers because they are technically demanding, and specialized training in bariatric endoscopy is still required.

AbstractThis joint ASGE-ESGE guideline provides an evidence-based summary and recommendations regarding the role of endoscopic bariatric and metabolic therapies (EBMTs) in the management of obesity. The document was developed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework. It evaluates the efficacy and safety of EBMT devices and procedures that currently have CE mark or FDA-clearance/approval, or that had been approved within five years of document development. The guideline suggests the use of EBMTs plus lifestyle modification in patients with a BMI of ≥30 kg/m2, or with a BMI of 27.0–29.9 kg/m2 with at least 1 obesity-related comorbidity. Furthermore, it suggests the utilization of intragastric balloons and devices for endoscopic gastric remodeling (EGR) in conjunction with lifestyle modification for this patient population.

AbstractBackground and AimEffective clinical event classification is essential for clinical research and quality improvement. The validation of artificial intelligence (AI) models like Generative Pre‐trained Transformer 4 (GPT‐4) for this task and comparison with conventional methods remains unexplored.MethodsWe evaluated the performance of the GPT‐4 model for classifying gastrointestinal (GI) bleeding episodes from 200 medical discharge summaries and compared the results with human review and an International Classification of Diseases (ICD) code‐based system. The analysis included accuracy, sensitivity, and specificity evaluation, using ground truth determined by physician reviewers.ResultsGPT‐4 exhibited an accuracy of 94.4% in identifying GI bleeding occurrences, outperforming ICD codes (accuracy 63.5%, P < 0.001). GPT‐4's accuracy was either slightly lower or statistically similar to individual human reviewers (Reviewer 1: 98.5%, P < 0.001; Reviewer 2: 90.8%, P = 0.170). For location classification, GPT‐4 achieved accuracies of 81.7% and 83.5% for confirmed and probable GI bleeding locations, respectively, with figures that were either slightly lower or comparable with those of human reviewers. GPT‐4 was highly efficient, analyzing the dataset in 12.7 min at a cost of 21.2 USD, whereas human reviewers required 8–9 h each.ConclusionOur study indicates GPT‐4 offers a reliable, cost‐efficient, and faster alternative to current clinical event classification methods, outperforming the conventional ICD coding system and performing comparably to individual expert human reviewers. Its implementation could facilitate more accurate and granular clinical research and quality audits. Future research should explore scalability, prompt and model tuning, and ethical implications of high‐performance AI models in clinical data processing.

Introduction Symptom burden management is a major goal of pancreatic cancer care given that most patients are diagnosed late. Early palliative care is recommended in addition to concurrent active treatment; however, disparities exist. We sought to determine the factors associated with inpatient palliative treatment among pancreatic cancer patients and compare treatment outcomes in terms of mortality, discharge disposition and resource utilization. Methods We conducted a retrospective study of 22,053 pancreatic cancers using the National Inpatient Sample (NIS) database (January - December 2020). Patient and hospital characteristics, mortality, discharge disposition, length of stay (LOS), hospital costs and charges were compared between pancreatic cancer patients based on palliative treatment. Multivariate regression was used to evaluate patient and hospital characteristics and outcomes associated with palliative treatment. Results A total number of 3839 (17.4%) patients received palliative care. Patients who received palliative care were more likely to be older, Medicaid insured, and nonobese. Patients were less likely to receive palliative care if they are males, Medicare insured, had a lower Charlson comorbidity score, or treated in Urban nonteaching hospitals. Patients who received palliative care displayed higher odds of in-hospital mortality and prolonged LOS. The adjusted additional mean hospital cost and charges in patients who received palliative care were lower by $1459, and $4222 respectively. Conclusions Inpatient palliative treatment in pancreatic cancer patients is associated with an older age, a higher comorbidity burden, non-obesity, insurance status and urban teaching hospitals. Our study suggests that inpatient palliative treatment decreased hospital resource utilization without prolonging survival.

Purpose of review The aim of this review is to present the current state of the field, highlight recent developments, and describe the clinical outcomes of these endoluminal bariatric and metabolic procedures. Recent findings The landscape of endoluminal devices and techniques for treating obesity has expanded significantly, with FDA-approved therapies currently available to patients with a body mass index values as high as 50 kg/m2. Although notable advancements have been made in this area, there is a need for further emphasis to be placed on the metabolic improvements resulting from these therapies, in addition to the conventional focus on weight loss outcomes. Some of these procedures are now FDA approved for the treatment of metabolic disease as opposed to weight loss. To achieve the most favorable results, it is imperative that all endoluminal interventions are combined with a moderately intensive diet and lifestyle program lasting at least 12 months. Summary Endoluminal metabolic and bariatric therapy represents a bridge between lifestyle counseling, pharmaceutical interventions, and the most efficacious treatment for obesity, bariatric surgery. By virtue of its minimally invasive approach, this therapy may be an appealing option for patients who are ineligible for, or averse to, bariatric surgery and who have experienced suboptimal outcomes or unable to afford medical treatments. Furthermore, these interventions may be particularly beneficial in the early stages of obesity.
