Area of Science:

  • Gastroenterology and Hepatology
  • Endoscopic Imaging

Background:

  • Cholangioscopy is an advanced endoscopic procedure.
  • It allows direct visualization of the biliary tree.

Purpose of the Study:

  • To showcase the technique of cholangioscopic examination.
  • To illustrate the visualization of the ampullary channel and extrahepatic bile duct.

Main Methods:

  • Video recording of a cholangioscopic procedure.
  • Examination of the ampullary channel.
  • Examination of the extrahepatic bile duct.

Main Results:

  • Successful visualization of the ampullary channel was achieved.
  • Successful visualization of the extrahepatic bile duct was achieved.

Conclusions:

  • Cholangioscopy provides detailed endoscopic views of the biliary system.
  • This technique is valuable for evaluating ampullary and bile duct pathologies.
