Endoscopic sphincterotomy (ES) is a safe procedure for most patients. With increased experience, the study found a significant decrease in hospital mortality and complications, suggesting improved outcomes over time.

Area of Science:

  • Gastroenterology
  • Surgical Endoscopy

Background:

  • Endoscopic sphincterotomy (ES) is a crucial intervention for biliary and pancreatic disorders.
  • While generally safe, ES carries risks of morbidity and mortality.
  • The impact of cumulative experience on ES outcomes has not been extensively reported.

Purpose of the Study:

  • To document the indications and outcomes of endoscopic sphincterotomy (ES) over a 7-year period.
  • To analyze potential improvements in ES results with increasing institutional experience.
  • To assess the safety and efficacy of ES in various clinical scenarios, including emergencies and malignant biliary obstruction.

Main Methods:

  • Retrospective analysis of 706 patients undergoing ES between 1987 and 1994.
  • Data collection included indications, success rates, complications, and mortality.

  • Outcomes were compared before and after 1990 to evaluate the effect of experience.

    • Main Results:

    • ES was successfully accomplished in 689 patients (97.6%).
    • Overall complication rate was 7.1%, with 1.8% requiring operative intervention.
    • Significant reductions in hospital mortality (p < 0.01) and operative interventions (p < 0.001) were observed after 1990.

    Conclusions:

    • Endoscopic sphincterotomy (ES) is a safe and effective procedure for a majority of patients.
    • Increasing procedural experience is associated with a significant reduction in ES-related morbidity and mortality.
    • ES can be safely performed in emergency settings and for malignant biliary obstruction without compromising outcomes.
