title: High complication rate of bile duct stents in patients with chronic alcoholic pancreatitis due to noncompliance.
abstract: OBJECTIVE
  Biliary obstruction in chronic pancreatitis is frequently treated by endoscopic insertion of a plastic stent into the common bile duct, a therapy regarded as having a low complication rate. The aim of this study is to analyze the frequency and severity of complications caused by biliary stents in patients with chronic alcoholic pancreatitis.
  
  
  METHODS
  We retrospectively analyzed all our patients with chronic pancreatitis (n = 14) who were provided with a plastic stent for biliary stenosis between June 1993 and December 1997. Stent exchanges were followed until December 1998.
  
  
  RESULTS
  Stent insertion was performed without early complications and was successful in each patient. Only two patients were admitted after 3-4 months at the scheduled dates for stent exchange, both without complications. In one of these patients, the bile duct stenosis was reopened after two stent exchanges over a total period of 8 months. Most of our patients (n=12) did not come at the arranged dates for stent exchange. They were repeatedly admitted (mean 2.9 times/patient, range 1-5) as emergency cases with severe complications of biliary obstruction, such as cholangitis or biliary sepsis. Reopening of the bile duct stenosis was not achieved in these patients.
  
  
  CONCLUSIONS
  We associate the high rate of complications with the noncompliance of our patients, who were all alcoholics. The high incidence of late complications in noncompliant patients is a limitation of biliary stenting, and appears to be potentially harmful.
