The Efficacy of Over-the-Scope Clip Closure for Gastrointestinal Iatrogenic Perforation During Endoscopic Ultrasound and Endoscopic Retrograde Cholangiopancreatography for Pancreaticobiliary Diseases

BACKGROUND: Intestinal perforation is a severe adverse event during pancreaticobiliary endoscopy. The use of over-the-scope clip (OTSC) has recently increased; however, the efficacy of OTSC during pancreaticobiliary endoscopy has not been well studied. AIMS: To evaluate the efficacy of OTSC for the closure of gastrointestinal iatrogenic perforation during pancreaticobiliary endoscopy. PATIENTS AND METHODS: This was a retrospective multicenter cohort study conducted at 3 tertiary care centers. The inclusion criteria were patients who had gastrointestinal perforation during endoscopic procedures for pancreaticobiliary diseases and underwent perforation closure using OTSC. The primary outcome was the clinical success rate. Secondary outcomes were technical success rates, adverse event rates, and the duration until the start of oral intake after OTSC. RESULTS: Ten patients were treated by OTSC from January 2013 to December 2017. In 2 out of 10, the perforations could not be closed completely. In the remaining 8, perforations were closed completely, but intestinal obstruction caused by OTSC occurred in 1 patient. The clinical success rate was 80% (8/10). The technical and adverse event rates were 80% (8/10) and 10% (1/10), respectively. A median resumption timing of oral intake was 5 days (range, 3 to 10 d). CONCLUSION: OTSC is considered as effective management for perforations during pancreaticobiliary endoscopy, although careful consideration is required for the indication of OTSC.
