Area of Science:

  • Gastroenterology
  • Endoscopic Procedures
  • Biliary Interventions

Background:

  • Conventional endoscopic sphincterotomy or cholangiography can fail to achieve biliary access.
  • Difficult biliary access poses challenges in diagnosis and treatment.

Purpose of the Study:

  • To evaluate the efficacy and safety of needle knife papillotomy for achieving biliary access after conventional methods failed.
  • To assess the success rate, morbidity, and mortality associated with needle knife papillotomy.

Main Methods:

  • Needle knife papillotomy was performed in 103 patients with failed conventional access for endoscopic sphincterotomy or cholangiography.
  • Success was defined as obtaining biliary access.
  • Procedure-related morbidity and mortality were recorded.

Main Results:

  • Overall success rate for needle knife papillotomy was 77% (79 out of 103 patients).
  • Access was achieved in 36 patients during the same session and in 43 patients within 2-5 days.
  • In the therapeutic group (endoscopic sphincterotomy), morbidity was 5.2% and mortality was 2.0%.
  • No deaths or complications occurred in the diagnostic cholangiography group.

Conclusions:

  • Needle knife papillotomy is an effective technique for achieving biliary access when conventional methods fail.
  • It serves as a valuable adjunct to existing endoscopic biliary access techniques.
  • The procedure demonstrated acceptable safety profiles, particularly in diagnostic indications.
