Simultaneous laparoscopic liver and diaphragm resection (SLLDR) is safe for selected colorectal liver metastases patients. This procedure offers good surgical and oncological outcomes, comparable to liver resection alone.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Colorectal liver metastases require curative treatment via liver resection or ablation.
  • Simultaneous liver and diaphragm resection is technically challenging and debated.
  • Assessing the safety of laparoscopic approaches for these complex cases is crucial.

Purpose of the Study:

  • To evaluate the safety and outcomes of simultaneous laparoscopic liver and diaphragm resection (SLLDR).
  • To compare SLLDR with standard laparoscopic liver resection (LLR) for colorectal liver metastases.

Main Methods:

  • Retrospective analysis of 467 patients undergoing LLR for colorectal liver metastases (2008-2019).
  • Comparison of 12 patients undergoing SLLDR (group 1) versus 455 patients undergoing LLR only (group 2).

  • Analysis of perioperative and oncologic outcomes, including conversion rates, operative time, blood loss, margins, and survival.

    • Main Results:

    • SLLDR had a higher conversion rate (16.7%) than LLR alone (2.4%, P=0.040).
    • Diaphragm resection was often performed en bloc with the liver tumor (83.3%).
    • No significant differences in operative time, blood loss, resection margins, hospital stay, or complications; overall survival was similar.

    Conclusions:

    • Simultaneous laparoscopic liver and diaphragm resection is a safe and effective option for selected patients.
    • The procedure achieves favorable surgical and oncological results, comparable to standard LLR.
