Area of Science:

  • Veterinary Surgery
  • Surgical Techniques
  • Canine Research Models

Background:

  • Total hepatectomy is a complex procedure.
  • Maintaining organ integrity during hepatectomy is challenging.
  • A canine model is valuable for surgical research.

Purpose of the Study:

  • To describe a new technique for total hepatectomy in dogs.
  • To ensure the gastrointestinal tract and pancreas remain functional.
  • To create a viable model for metabolic studies.

Main Methods:

  • A surgical technique involving a mesentericocaval shunt.
  • Implementation of a temporary external bypass between femoral and jugular veins.
  • Creation of a permanent internal bypass via the diaphragm for vena cava connection.

  • Preservation of the gastrointestinal tract and pancreas.
  • Procedure duration of 60-70 minutes.

Conclusions:

  • The described technique allows for total hepatectomy in dogs.
  • This method provides a short-term model for studying nonhepatic tissues.
  • The procedure maintains essential organ function during the study period.
