Summary
Major laparoscopic liver resections (LLRs) are complex but achievable. This study of 1184 major LLRs across 18 centers shows a 10% conversion rate and 96.5% negative margins, highlighting the need for specialized training.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Surgery
- Surgical Oncology
Background:
- Minor laparoscopic liver resections (LLRs) are standardized, but major LLRs are performed by few expert teams.
- There is a need to consolidate international experience in major LLRs to assess outcomes and techniques.
Purpose of the Study:
- To report combined data from 18 international centers on major laparoscopic liver resections (LLRs).
- To evaluate technical aspects, outcomes, and challenges associated with major LLRs.
Main Methods:
- Retrospective analysis of 5388 LLRs (1996-2014), including 1184 major LLRs.
- Data collected on LLR type, indications, synchronous resections, technical details, conversion rates, operative time, blood loss, and surgical margins.
Main Results:
- Colorectal liver metastases were the most frequent indication for laparoscopic right hepatectomy (LRH) (37.0%).
- The overall conversion rate for major LLRs was 10%, with a mean operative time of 291 minutes.
- Mean estimated blood loss was 327 ml, and the negative surgical margin rate was 96.5%.
Conclusions:
- Major LLRs remain challenging procedures demanding significant expertise in laparoscopy and liver surgery.
- Encouraging and training new surgeons in these techniques is crucial for the advancement of this surgical field.
