title: Endoscopic stenting for common bile duct stenoses in chronic pancreatitis: results and impact on long-term outcome.
abstract: OBJECTIVE
  The overall incidence of common bile duct strictures due to chronic pancreatitis is reported to be approximately 10-30%. It remains a challenging problem for gastroenterologists and surgeons. The exact role of endoscopic stenting has not yet been clearly defined.
  
  
  METHODS
  Thirty-nine patients with chronic pancreatitis and symptomatic common bile duct stenoses underwent endoscopic stenting and were studied retrospectively. We were particularly interested in how many patients would achieve resolution of the stricture and tolerate removal of the stents in the long term.
  
  
  RESULTS
  Indications for endoscopic stenting were symptomatic cholestasis, jaundice or cholangitis. The initial serum bilirubin was 8.3 mg/dl and the diameter of the common bile duct was 14.2 mm before stenting. Within 3-7 days of stenting, all patients presented improvement of jaundice and cholestasis. After a median stenting time of 9 months (range 1-144 months), 46% of the patients demonstrated regression of the stricture and clinical improvement, 26% required further stenting, and 28% were referred to surgery. Five patients received a self-expandable metal Wallstent. Thirty-one per cent demonstrated complete clinical recovery of the stricture as well as 10.2% a complete, radiologically verified stricture regression in a median follow-up of 58 months.
  
  
  CONCLUSIONS
  There seems to be a therapeutic benefit for short-term endoscopic treatment but medium-term and long-term outcome remains questionable. Endoscopic stenting should be applied as an initial therapy before surgery, but it can be the definitive approach for older and morbid patients or cases with complete stricture regression after stent removal. Overall, it should not be considered as a routine procedure for symptomatic cases.
