RETRACTED: Endoscopic Treatment of Endoscopic Retrograde Cholangiopancreatography-Related Duodenal Perforations (Retracted Article)

Background: Endoscopic retrograde cholangiopancreatography (ERCP)-related duodenal perforation is a rare complication associated with significant morbidity and mortality. This study evaluated endoscopic management experience and outcomes of ERCP-related duodenal perforations. Materials and Methods: Between March 2005 and March 2017, a total of 19,468 ERCP procedures were performed in three endoscopy units of three hospitals in China. Diagnoses, management, and outcomes were identified and retrospectively reviewed in 58 of these patients. Results: According to the classification system, 58 patients included 8 with type I, 44 with type II, 4 with type III, and 2 with type IV perforation. Of type I perforations, 7 patients underwent endoscopic closure with endoclips, and 1 patient was treated with surgical repair. Of type II perforations, 11 patients were actively managed using the fully covered self-expandable metallic stents (SEMS) to seal the perforation, and 33 patients were passively managed using nose-biliary drainage, in which 13 cases had retroperitoneal abscess formation and were successfully treated by abdominal computed tomography (CT)-guided percutaneous external drainage, but 1 patient died due to sepsis. One patient with type III perforation (pancreatic duct perforation) underwent endoscopic pancreatic duct stent placement after surgery failure. The mean hospital stay of 11 cases with type II perforation treated actively by endoscopy (26.53.3 days) was lower compared with 33 cases who received passive conservative treatment (34.6 +/- 3.9 days). Conclusion: Many (especially type I and II) ERCP-related duodenal perforations can be successfully treated with endoscopic management. Active endoscopic therapy may be better than passive conservative treatment for type II perforations.
