Abstract

Intestinal perforation from a migrated biliary stent is a known complication of endoscopic biliary stent placement. We present a case of stent migration and resultant duodenal perforation after stent placement for a malignant biliary stricture in a 52-year-old woman. We review the current literature on the diagnosis and management of stent migration and intestinal perforation after endoscopic stent placement for biliary strictures. A plain abdominal radiograph is necessary for early diagnosis of biliary stent migration. If a stent becomes lodged in the gastrointestinal tract, endoscopic or operative extraction of the stent is necessary to prevent subsequent intestinal perforation and peritonitis. Intestinal perforation secondary to biliary stent dislocation should be considered in all patients presenting with fever and abdominal pain after biliary stent insertion. Any abnormality that prevents stent migration through the intestinal tract such as gastroenterostomy, abdominal wall hernia, extensive adhesions or colonic divertucula may be a contraindication for insertion of a plastic biliary stent because of increased perforation risk.
