Area of Science:

  • Gastroenterology and Hepatology
  • Surgical Anatomy
  • Medical Imaging

Background:

  • Accurate knowledge of biliary duct anatomy is vital for safe endoscopic and surgical interventions.
  • Variations in the cystic and common hepatic duct junction can complicate procedures.
  • Retrospective analysis of cholangiograms is a key method for studying biliary anatomy.

Observation:

  • The cysticohepatic junction was visualized in 70% of 524 evaluated cholangiograms.
  • Medial junctions (18%) and spiral configurations (32%) were more frequent than previously reported.
  • Parallel duct systems occurred in 11%, and distal cystic duct entry in 10% of cases.

Findings:

  • Common variations include medial and spiral configurations of the cysticohepatic junction.

  • Anomalous cystic duct entry points into the hepatic duct were observed.
  • The frequency of certain anatomical variations differs from prior literature.

    • Implications:

    • Understanding these anatomical variations is essential for preventing complications during biliary endoscopy and cholecystectomy.
    • Improved visualization techniques and anatomical awareness can enhance procedural safety.
    • This data aids in refining surgical planning and endoscopic techniques for biliary tract diseases.
