DUODENAL PERFORATION INTO RETROPERITONEUM BY A BILIARY STENT
Abstract
Migration of endoscopically placed biliary stents is a well-recognized complication of endoscopic retrograde cholangiopancreatography (ERCP). Duodenal perforation by a biliary stent is an uncommon but hazardous complication associated with a high mortality rate. It can be either retroperitoneal, causing biloma, or intraperitoneal leading to biliary peritonitis. Duodenal perforation into the retroperitoneum presents itself as a non-specific condition. It requires an extremely high index of suspicion for its early diagnosis. A delayed diagnosis seriously aggravates the prognosis. We report a case of mortality secondary to a duodenal perforation into retroperitoneum by a biliary stent endoscopically placed with an atypical symptomatology.
