Fully Covered Self-Expandable Metal Stens eliminate surgical repair requirement in both endoscopic sphincterotomy and precut sphincterotomy-related perforation (with video).

Abstract

Endoscopic retrograde cholangiopancreatography (ERCP)-related perforations occur in 0.3-0.6% of patients. The treatment of retroperitoneal paravaterian perforations (type II), which develop during endoscopic sphincterotomy or precut sphincterotomy, remains a matter of debate. We aimed to evaluate the efficacy of fully covered self expandable metal stent (Fc-SEMS) placement in the treatment of type II perforations. The study was conducted in a tertiary ERCP reference center of Turkey between December 2013 and June 2016. Patients with type II ERCP-related perforation constituted the study group. Type II perforations were treated by insertion of an Fc-SEMS (10 mm × 60 mm) during the ERCP procedure or intraoperatively by surgery-endoscopy rendezvous technique, if biliary cannulation could not be achieved. A total of 2689 ERCPs were performed. ERCP-related perforation was observed in 12 procedures (0.4%). Eight patients had Stapfer type II perforations, which developed during endoscopic sphincterotomy in seven patients and precut sphincterotomy in one patient. Fc-SEMSs were inserted during the ERCP procedure in seven patients and intraoperatively by surgery-endoscopy rendezvous technique in one patient. None of the patients developed fever, hemodynamic instability, or peritoneal signs. Stents were removed after a median duration of 9 (3-14) days. All of the patients were uneventfully discharged after an average hospital length of stay of median 5 (1-9) days. Fc-SEMSs are highly effective in the nonoperative treatment of type II perforations and their intraoperative insertion in patients with unsuccessful cannulation may facilitate surgery by eliminating the need for duodenum repair surgery.
