Single-channel endoscopic closure of large endoscopy-related perforations.

Background and study aims: Gastrointestinal endoscopy procedures, such as endoscopic retrograde cholangiopancreatography (ERCP), endoscopic submucosal dissection (ESD), and colonoscopy are widely used for the diagnosis or treatment of digestive diseases. Perforation is a rare but potentially lethal complication. Large perforations usually require immediate endoscopic or surgical repair. Endoscopic closure using a nylon loop pouch suture is usually performed with a double-channel endoscope. This paper describes the endoscopic closure of large procedure-related perforations using a single-channel endoscope. Patients and methods: A total of 10 patients with large perforations (2.5-4.0 cm), which occurred during ERCP, ESD, or colonoscopy, were treated using the single-channel endoscope technique. Results: All perforations were successfully closed using a nylon loop pouch suture through the single- channel endoscope. No surgery or further endoscopic intervention was required. Conclusions: Nylon loop pouch suture through a single-channel endoscope was easy to perform and was feasible for the closure of large gastrointestinal perforations. [ABSTRACT FROM AUTHOR]
