title: Efficacy and safety of therapeutic ERCP for the elderly with choledocholithiasis: comparison with younger patients.
abstract: OBJECTIVE
  To clarify the efficacy and safety of therapeutic endoscopic retrograde cholangiopancreatography for the elderly with choledocholithiasis compared with younger patients.
  
  
  METHODS
  Consecutive therapeutic ERCPs performed between 2005 and 2007 at our institution for 118 patients aged 80 years or older (group A) and 205 patients younger than 80 years old (group B) were retrospectively reviewed. Successful cannulation rate, complete stone clearance rate, complications and prognosis were compared between the two groups.
  
  
  RESULTS
  Successful cannulation was achieved in 99.2% in group A versus 99.5% in group B. The complete stone clearance rate was significantly lower in group A than in group B (92.4% versus 99.0%, p<0.01). Plastic stent placement was performed for patients with incomplete duct clearance. There was no significant difference in the early complication rate between group A (5.5%) and group B (6.6%). Procedure-related mortality did not occur. Cholangitis-free survival was similar between the two groups. The short-term prognosis was comparable between those with complete duct clearance and those with biliary stent placement.
  
  
  CONCLUSIONS
  With a duct clearance rate of more than 90% and plastic stent placement for patients with poor general condition, therapeutic ERCP for choledocholithiasis in patients 80 years of age or older is comparable in safety and effectiveness to that in younger patients.
