    Area of Science:

    • Hepatobiliary surgery
    • Surgical anatomy
    • Minimally invasive techniques

    Background:

    • Hepatic resection is increasingly accepted due to advanced imaging.
    • Liver anatomy comprises eight segments, allowing for segmental resections.
    • Improved imaging enhances the precise definition of liver abnormalities.

    Purpose of the Study:

    • To describe liver segmental anatomy.
    • To detail the use of the ultrasonic dissector for hepatic resection.
    • To evaluate the safety and efficacy of ultrasonic dissector-assisted segmental hepatic resection.

    Main Methods:

    • Descriptive report of liver segmental anatomy.
    • Application of ultrasonic dissector for transparenchymatous segmental resection.
    • Retrospective analysis of 13 patients undergoing segmental hepatic resection.

    Main Results:

    • Mean operative time was 128 +/- 57 minutes.
    • Mean blood loss was 830 +/- 623 mL.
    • Five patients had underlying cirrhosis.

    Conclusions:

    • Segmental hepatic resection with an ultrasonic dissector is feasible.
    • This technique facilitates resection without vascular inflow/outflow control.
    • Ultrasonic dissector use may enhance versatility in managing hepatic and biliary diseases.
