Abstract

An 85-year-old woman underwent endoscopic retrograde cholangiopancreatography (ERCP) for obstructive jaundice. Selective bile duct cannulation was unsuccessful because of periampullary diverticula (PAD). A pancreatic spontaneous dislodgement stent (PSDS) (5F diameter, 3 cm, straight type) was inserted to prevent post-ERCP pancreatitis. Three days after ERCP, she complained of abdominal pain, and computed tomography revealed retroperitoneal perforation because of PSDS migration to the PAD. If the papillary orifice is observed at the diverticular rim or in the diverticula, a pigtailed PSDS on the duodenal side or flanged stent on the pancreatic ductal side should be inserted in order to prevent this rare adverse event.
