Summary

Expert biliary endoscopists show less variation in ampullectomy techniques than previously thought. Practices for endoscopic ampullectomy, including imaging and stenting, are becoming more standardized among specialists.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Ampullectomy is a key endoscopic procedure for ampullary neoplasms.
  • Variability in ampullectomy practices exists in the current literature.

Purpose of the Study:

  • To investigate and define current endoscopic ampullectomy practices among expert biliary endoscopists.
  • To identify trends and variations in techniques used by specialists.

Main Methods:

  • Anonymous survey distributed to 79 expert biliary endoscopists.
  • Assessed practices regarding pre-procedure imaging, sphincterotomy, pancreatic stenting, tissue removal, and follow-up.

Main Results:

  • 58% responded; 63% in academia, 16.4 years average practice.
  • Endoscopic ultrasound commonly used (67% always).

Endaural Endoscopic Atticoantrotomy (Retrograde Mastoidectomy) using a Constant Suction Bone-drilling Technique

Published on: May 23, 2021

  • Biliary sphincterotomy use varied (26% always, 37% sometimes). Pancreatic sphincterotomy rarely used (53% never).
  • High ERCP volume linked to pancreatic sphincterotomy (OR=10.9).
  • Prophylactic pancreatic stent favored post-resection (86%). Argon plasma coagulation preferred for residual tissue (83%).
  • Uniform follow-up within 6 months.

    • Conclusions:

    • Practices among expert biliary endoscopists are more consistent than literature suggests.
    • Standardization in ampullectomy techniques is emerging among specialists.
