Description: Open the capsule, quit the cigarettes, and know when to cut: the essentials of managing marginal ulcers after bypass.Marginal ulcers are among the most common complications after Roux-en-Y gastric bypass, with a pooled prevalence around 4.6%, and they span everything from mild postprandial pain to perforation with peritonitis. In this episode, our expert panel works through three clinical scenarios (an uncomplicated early ulcer, a refractory ulcer with recurrent stricture, and a perforated ulcer with peritonitis) to build a practical framework for prevention, workup, medical therapy, and surgical escalation.Hosts Matthew Martin, trauma and bariatric surgeon at the University of Southern California/Los Angeles General Medical Center (Los Angeles, California) Adrian Dan, bariatric and MIS surgeon, program director for the advanced MIS bariatric and foregut fellowship at Summa Health System (Akron, Ohio) Crystal Johnson Mann, bariatric and foregut surgeon at the University of Florida (Gainesville, Florida) Katherine Cironi, general surgery resident at the University of Southern California/Los Angeles General Medical Center (Los Angeles, California)  Learning objectives1.     Identify the established and debated risk factors for marginal ulcers. Recognize smoking, diabetes, NSAIDs, and larger pouch size as key contributors. Appreciate that the role of H. pylori remains unsettled because of heavy heterogeneity across meta-analyses.2.     Perform a complete etiologic workup for a new marginal ulcer. Assess NSAID and immunosuppressant use, smoking (including cotinine test), H. pylori status, and visible suture or staple material at the anastomosis, and know that endoscopy, not CT, is the diagnostic tool of choice unless perforation is suspected.3.     Optimize first-line medical management. Use PPI therapy with instructions to open the capsules for faster healing, understand the limited evidence for adding sucralfate, confirm healing with repeat endoscopy, and individualize treatment duration, including when lifelong prophylaxis is reasonable.4.     Define and evaluate the refractory ulcer. Apply the 6- to 12-month definition of refractory disease, rule out gastrogastric fistula, hypersecretory states (serum gastrin), and PPI rapid metabolism (CYP2C19), and recognize ulcer-related gastrojejunal stricture and the perforation risk of serial dilation.5.     Weigh escalation options for refractory disease. Compare endoscopic suturing and stenting, truncal vagotomy, and GJ revision, including their mixed durability data, and address nutritional optimization and remnant access before reoperation.6.     Manage a perforated marginal ulcer. Prioritize resuscitation, antibiotics, and IV PPI; take unstable patients straight to the OR, use primary repair with omental patch as the default approach, and reserve revision or damage control for select patients based on physiology, tissue quality, and expertise.7.     Counsel patients on long-term recurrence risk. Communicate substantial recurrence rates after both repair and revision and emphasize that quitting smoking early (more than a year before surgery) meaningfully lowers reoperation risk.Please visit https://behindtheknife.org to access other high-yield surgical education podcasts, videos and more.  If you liked this episode, check out our recent episodes here: https://behindtheknife.org/listenBehind the Knife Premium: https://behindtheknife.org/premiumOral Board Review: https://behindtheknife.org/oral-boardOral Board Simulator: https://behindtheknife.org/oral-board/simulatorGeneral Surgery Oral Board Review Course: https://behindtheknife.org/premium/general-surgery-oral-board-reviewTrauma Surgery Video Atlas: https://behindtheknife.org/premium/trauma-surgery-video-atlasDominate Surgery: A High-Yield Guide to Your Surgery Clerkship: https://behindtheknife.org/premium/dominate-surgery-a-high-yield-guide-to-your-surgery-clerkshipDominate Surgery for APPs: A High-Yield Guide to Your Surgery Rotation: https://behindtheknife.org/premium/dominate-surgery-for-apps-a-high-yield-guide-to-your-surgery-rotationVascular Surgery Oral Board Review Course: https://behindtheknife.org/premium/vascular-surgery-oral-board-reviewColorectal Surgery Oral Board Review Course: https://behindtheknife.org/premium/colorectal-surgery-oral-board-reviewSurgical Oncology Oral Board Review Course: https://behindtheknife.org/premium/surgical-oncology-oral-board-reviewCardiothoracic Oral Board Review Course: https://behindtheknife.org/premium/cardiothoracic-surgery-oral-board-reviewOBGYN Oral Board Review Course: https://behindtheknife.org/course/obgyn-oral-board-reviewSurgical Critical Care Review: https://behindtheknife.org/premium/surgical-critical-care-reviewABSITE Question Bank: https://behindtheknife.org/premium/absite-question-bankEPA Playbook: https://behindtheknife.org/course/epa-playbookSurgical Instrument Flashcards: https://behindtheknife.org/course/surgical-instrument-flashcardsABSITE Review: https://behindtheknife.org/course/absite-2026-exam-reviewDownload our App:Apple App Store: https://apps.apple.com/us/app/behind-the-knife/id1672420049Android/Google Play: https://play.google.com/store/apps/details?id=com.btk.app&hl=en_US
