Laparoscopic simultaneous resection (LSR) for colorectal tumors with liver metastases is feasible. High-difficulty liver resection, right-sided colectomy, and American Society of Anesthesiologists (ASA) classification ≥3 are key risk factors for complications.

Area of Science:

  • Surgical Oncology
  • Hepatobiliary Surgery
  • Colorectal Surgery

Background:

  • Laparoscopic simultaneous resection (LSR) is a novel approach for primary colorectal tumors and synchronous colorectal liver metastases (sCRLM).
  • Postoperative outcomes and risk factors for resection surface-related complications (RSRC) after LSR require further investigation.

Purpose of the Study:

  • To evaluate the postoperative outcomes of LSR for sCRLM.
  • To identify independent risk factors for RSRC, including biliary fistula and liver-transection surface abscess.

Main Methods:

  • Retrospective analysis of 112 patients with sCRLM who underwent LSR between 2009 and 2022.
  • Assessment of clinicopathological data, intraoperative factors, and postoperative outcomes.
  • Classification of liver resection difficulty using the IWATE difficulty scoring system (DSS) and multivariate analysis for RSRC risk factors.
Synchronous colorectal cancer liver metastases

Main Results:

  • LSR was performed in 112 patients, with 94 undergoing partial hepatectomy and colorectal surgery.
  • The most frequent complication was RSRC (17.0%), with no postoperative mortality.
  • Independent risk factors for RSRC included American Society of Anesthesiologists (ASA) classification ≥3, DSS score ≥7, and right-sided colectomy.

Conclusions:

  • LSR demonstrates acceptable short-term outcomes for sCRLM in experienced centers.
  • RSRC is the most common complication, with specific surgical and patient factors increasing its risk.
  • Identifying these risk factors can help optimize patient selection and surgical planning for LSR.
