This study introduces a simplified protocol for laparoscopic right hepatectomy (LapRH), addressing key surgical challenges. The streamlined technique enables safe and successful minimally invasive liver resection procedures.

Area of Science:

  • Hepatobiliary Surgery
  • Minimally Invasive Procedures
  • Surgical Technique Optimization

Background:

  • Laparoscopic right hepatectomy (LapRH) presents significant challenges, including complex liver mobilization, difficulties with the hanging maneuver, and reliance on experienced surgical assistants.
  • Existing protocols for LapRH often lack standardization, potentially hindering widespread adoption and consistent outcomes.
  • The need for simplified, reproducible techniques in LapRH is critical for improving patient safety and surgical efficiency.

Observation:

  • A novel six-step protocol for LapRH was developed, focusing on curtailed mobilization, direct vascular control, and alternative retraction methods.
  • The simplified technique replaces the traditional hanging maneuver with a lifting-up approach using standard laparoscopic graspers or retractors.
  • The procedure was systematically broken down to enhance clarity and facilitate easier execution by surgical teams.

Findings:

  • In a series of 13 LapRH procedures, the simplified protocol demonstrated feasibility with a low conversion rate to open surgery (1/13).
  • Mean operative time was 381 minutes with an average blood loss of 633 ml, indicating manageable surgical parameters.
  • No significant postoperative complications were observed, and the mean hospital stay was 9.1 days, suggesting favorable patient recovery.

Implications:

  • Protocolization and simplification of LapRH can enhance understanding and execution of the procedure, potentially improving port placement and overall surgical performance.
  • This simplified approach may broaden the accessibility of safe and effective minimally invasive liver resections.
  • Further adoption of this protocol could lead to standardized training and improved outcomes in laparoscopic liver surgery.
