Area of Science:

  • Hepatobiliary Surgery
  • Surgical Anatomy
  • Vascular Anatomy

Background:

  • Right trisectionectomy carries risks due to potential anatomical variations.
  • Variations in the common bile duct, hepatic ducts, and segmental vasculature can lead to technical errors.

Purpose of the Study:

  • To identify and discuss anatomical variations that may predispose to errors in right trisectionectomy.
  • To enhance surgical understanding of biliary and vascular anomalies relevant to this procedure.

Main Methods:

  • Intraoperative cholangiography in 112 patients analyzed common bile duct confluence variations.
  • Morphological examination of afferent and efferent blood supply variations in 43 liver resections.

Main Results:

  • Seven common bile duct confluence types identified intraoperatively, with three from literature.
  • Three bile drainage types for segment 4 (central, peripheral, combined) were established.
  • Mean left hepatic duct length was 3.68 cm; arterial and venous supply peculiarities of segments 2 and 3 were detailed.

Conclusions:

  • Knowledge of biliary and hepatic vascular variations is essential for safe right trisectionectomy.
  • Increased surgical experience and refined techniques further improve outcomes.
