Endoscopic Management of Recalcitrant Marginal Ulcers by Covering the Ulcer Bed.

Abstract

Management options for marginal ulcers (MU) vary from medical therapy to revision surgery. Medical therapy is often ineffective and revision surgery is associated with a high morbidity and possible recurrence. To evaluate technical feasibility, efficacy, and safety of endoscopic management of MU by covering the ulcer bed using oversewing and/or deploying a fully covered self-expandable metallic stent (FCSEMS). Medical records of consecutive patients who underwent endoscopic suturing and/or FCSEMS deployment for recalcitrant MU between August 2016 and June 2017 at a single academic center were reviewed. Recalcitrant MU was defined as an ulcer that persists after 6 to 8weeks despite maximal medical therapy (open capsule PPI, 40mg bid as well as sucralfate qid), cessation of smoking and nonsteroidal anti-inflammatory drugs (NSAIDs), and Helicobacter pylori eradication. Eleven patients (age range 31-60; all females) with mean BMI of 27.72± 5.93kg/m2 underwent endoscopic suturing and/or stent deployment for recalcitrant MU with abdominal pain at a median of 50months (range 3-120) post-Roux-en-Y gastric bypass (RYGB). Seven patients were managed by oversewing, two were managed by FCSEMS, and two patients required both. Technical success was 100%. All patients reported resolution of abdominal pain at 1week. Surveillance endoscopy performed in 10/11 (90.9%) patients at 8weeks revealed complete ulcer healing in 9/10 (90%). No adverse events were reported. Endoscopic management is an effective and safe method to treat MU and should be considered an alternative to surgical revision. It appears effective for perforated and recalcitrant MU.
