title: Endoscopic biliary endoprosthesis in elderly patients with large bile duct stones: long-term follow-up.
abstract: OBJECTIVE
  To assess the long-term evolution of elderly patients with large or impacted bile duct stones, treated by an endoscopic biliary endoprosthesis.
  
  
  METHODS
  Case series.
  
  
  METHODS
  Tertiary care center.
  
  
  METHODS
  Twenty-three patients with a mean (+/- SD) age of 86 +/- 5 years (range, 77-97 years). On admission, 96% were highly symptomatic. These patients represent 8.4% of a group of 273 elderly patients (greater than or equal to 70 years old) with choledocholithiasis treated by endoscopic sphincterotomy between November 1984 and May 1989.
  
  
  METHODS
  Endoscopic insertion of a biliary endoprosthesis.
  
  
  RESULTS
  Eight-seven percent (20/23) remained completely free of biliary symptoms and died of unrelated illness (48%) after a mean follow-up of 23 months or are still alive (39%) with a mean follow-up of 52 months. In four cases, this asymptomatic evolution now extends for more than 5 years.
  
  
  CONCLUSIONS
  Insertion of a biliary endoprosthesis offers an effective method for long-term treatment of non-extractable biliary stones in elderly patients.
