Abstract:
Laparoscopic sleeve gastrectomy is now the most commonly performed bariatric surgery. Although considered a safe procedure, adverse events such as staple line leak in the context of sleeve stenosis can result in significant patient morbidity and health economic burden. Correction of the downstream stenosis is mandatory for closure of the staple line leak. Conventional endoscopic therapies offer high initial success rates, though ultimately a significant proportion proceed to revision surgery. Gastric per-oral endoscopic myotomy (G-POEM) is a novel, minimally invasive procedure which allows for a full-thickness myotomy of the stenosed segment, potentially conferring similar anatomical correction to surgical seromyotomy. We present a case of recalcitrant chronic proximal staple line leak in the context of a downstream gastric stenosis managed by G-POEM.
