Area of Science:

  • Gastroenterology
  • Endoscopic Procedures

Background:

  • Endoscopic examination of the biliary tract can be performed using either rigid or flexible instruments.
  • Access to the biliary tract is typically achieved via the cystic duct or choledochotomy.

Purpose of the Study:

  • To describe the methodology and findings of endoscopic examinations of the biliary tract.
  • To detail the normal appearance of the biliary duct wall and the papilla of Vater region.
  • To emphasize the assessment of papilla function during endoscopic examination.

Main Methods:

  • Instruments (rigid or flexible) were introduced via the cystic duct or choledochotomy.
  • Examination focused on the distal biliary tract, including the papilla of Vater, followed by the proximal biliary system.
  • Papilla function was assessed by observing its response to fluid infusion.

Main Results:

  • The normal biliary duct wall appears yellowish-red without visible vascular structures.
  • The papilla of Vater region exhibits a characteristic honeycomb appearance.
  • Papilla function was evaluated, noting its opening and closing dynamics.

Conclusions:

  • Endoscopic examination provides detailed visualization of the biliary tract.
  • Assessment of the papilla of Vater's appearance and function is a key component of these examinations.
  • The study reports findings from 935 endoscopic examinations of the biliary system.
