Endoscopic sphincterotomy (EST) became safer with fewer complications and lower mortality over time. However, success rates for common bile duct stones and long-term outcomes, particularly for papillary stenosis, did not significantly improve despite new techniques.

Area of Science:

  • Gastroenterology
  • Endoscopic procedures
  • Biliary tract interventions

Context:

  • Comparative analysis of two large-scale endoscopic sphincterotomy (EST) series (1974-1980 and 1981-1986) across multiple centers.
  • Evaluation of evolving indications for EST, including choledocholithiasis and papillary stenosis.
  • Assessment of procedural safety, efficacy, and long-term outcomes.

Purpose:

  • To compare the outcomes of endoscopic sphincterotomy (EST) between two distinct time periods.
  • To analyze trends in indications, success rates, complication rates, and mortality associated with EST.
  • To evaluate the long-term efficacy and potential late complications of EST.

Summary:

  • A significant decrease in complication rates (7.55% to 5.04%) and mortality (1.12% to 0.60%) was observed in the later series of endoscopic sphincterotomies (EST).

  • While the overall success rate for clearing common bile duct stones remained stable (around 84%), long-term follow-up revealed increased rates of recurrent stones and EST stenosis in the later period.
  • Endoscopic sphincterotomy (EST) demonstrated improved safety but did not show appreciable improvements in therapeutic outcomes, especially for papillary stenosis, when comparing the two study periods.

    • Impact:

    • Highlights the trade-off between improved safety and static long-term efficacy in endoscopic sphincterotomy (EST).
    • Underscores the need for continued research into improving the durability and long-term success of biliary endoscopic procedures.
    • Provides valuable data for clinicians regarding the evolving role and outcomes of EST in managing biliary tract conditions.
