Esophagopericardial fistula: an unexpected dreaded complication of treatment of leak following revisional sleeve gastrectomy by endoscopic internal drainage.

Esophagopericardial fistula (EPF) is an uncommon but life-threatening complication of upper gastrointestinal tract surgery or endoscopy, which is related to anastomotic breakdown, chronic infection or esophageal traumatism. We first describe the first case of an EPF secondary to double pigtail drain migration: an endoscopic internal approach for the treatment of leak following revisional sleeve gastrectomy.
