    Summary

    A novel three-stage microsurgical procedure enables total hepatectomy in rats. This technique, beneficial for metabolic studies, achieved 65% survival at 18 hours in anhepatic rats.

    Area of Science:

    • Surgical techniques
    • Animal models
    • Physiology

    Background:

    • Total hepatectomy is crucial for studying liver function and metabolism.
    • Previous methods for rat hepatectomy have limitations.
    • Microsurgical approaches offer potential for improved outcomes.

    Purpose of the Study:

    • To describe a refined three-stage microsurgical procedure for total hepatectomy in rats.
    • To evaluate the feasibility and survival rates of this technique.
    • To establish a model for metabolic studies in anhepatic rats.

    Main Methods:

    • A three-stage surgical procedure involving suprarenal inferior vena cava manipulation, modified portacaval shunt construction, and total hepatectomy.
    • Extensive use of microsurgical techniques, particularly for shunt placement and hemorrhage control.
    • Post-operative monitoring of survival and body temperature.

    Main Results:

    • All rats survived the initial 6-hour study period.
    • A 65% survival rate was achieved at 18 hours post-hepatectomy.
    • Body temperature was maintained between 35-37°C throughout the study.

    Conclusions:

    • The described three-stage microsurgical procedure is a viable method for total hepatectomy in rats.
    • This technique facilitates the creation of anhepatic models for metabolic research.
    • The method is recommended based on successful application in 165 hepatectomies.
