Endoscopic suturing versus endoscopic clip closure of the mucosotomy during a per-oral endoscopic myotomy (POEM): a case-control study.

Introduction Obtaining an adequate mucosal closure is one of the crucial steps in per-oral endoscopic myotomy (POEM). Thus far, there have been no objective data comparing the various available closure techniques. This case-controlled study attempts to compare the application of endoscopic clips versus endoscopic suturing for mucosotomy closure during POEM cases.
