Abstract

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.
