Closure of a giant gastroesophageal mucosal tear after peroral endoscopic myotomy with over-the-scope clip and cyanoacrylate.

Abstract

Insufflation-associated adverse events after peroral endoscopic myotomy (POEM) are frequent although innocuous in most of the patients [1] [2]. However, mucosal injuries could lead to perforation, mediastinitis, or bleeding that could be potentially fatal if not treated appropriately. Hemoclips, over-the-scope (OTS) clips [3], fully covered self-expandable metal stents (FCSEMSs) [4], and cyanoacrylate [5] have been used as alternative treatments for these cases.
