Summary

Hepatic pedicle clamping (HPC) significantly reduces blood transfusions during liver resections. This safe and effective technique is crucial for improving outcomes in hepatectomy procedures.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Oncology
  • Gastroenterology

Background:

  • Minimizing operative bleeding and transfusions is key to evaluating liver resection success.
  • Hepatic pedicle clamping (HPC) is a common method to control bleeding during hepatectomies.
  • This study assesses HPC's safety, efficacy, technique, and contraindications in liver resections.

Purpose of the Study:

  • To evaluate the safety and efficacy of hepatic pedicle clamping (HPC) during liver resections.
  • To compare outcomes of liver resections performed with and without HPC.
  • To analyze the technique and contraindications associated with HPC.

Main Methods:

  • Analysis of data from 245 liver resections.
  • 125 resections utilized HPC (continuous or intermittent), with an average ischemia time of 39 minutes.

  • 120 resections were performed without HPC.

    • Main Results:

    • No operative mortality; 2.9% postoperative mortality and 22.4% morbidity.
    • HPC group showed significantly lower transfusion rates (34.4% vs. 60.0%) and fewer blood units transfused.
    • Postoperative blood chemistry differences were minimal and related to operation complexity, not HPC duration.

    Conclusions:

    • Hepatic pedicle clamping is a safe and effective technique for liver resection.
    • HPC is used continuously, intermittently for impaired liver function, and avoided in specific cases.
    • The study supports HPC's role in reducing transfusions and improving liver resection outcomes.
