title: Sigmoid colonic perforation and pelvic abscess complicating biliary stent migration.
abstract: Endoscopically placed biliary stents are a well-established procedure for the treatment of benign and malignant causes of obstructive jaundice in patients unfit for definitive surgical intervention. Stent migration has been described, though in most instances the stent will pass or remain in the bowel lumen for extended periods of time. Only a few cases of clinically significant complications of stent migration have been reported. This is the first case report of a pelvic abscess complicating stenting for choledocholithiasis. As the numbers of stenting procedures continue to increase it may be anticipated that the numbers of complications will similarly increase.
