Summary
Laparoscopic liver surgery (LLS) for benign liver tumors is safe and effective, with excellent outcomes. However, surgeons should carefully select cases, as indications for resection are becoming more restricted.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Surgery
- Surgical Oncology
Background:
- Laparoscopic liver surgery (LLS) was initially indicated for benign liver lesions.
- Indications for LLS have shifted towards malignant diseases.
- The role of LLS in treating benign liver tumors requires further evaluation.
Purpose of the Study:
- To evaluate the indications and outcomes of LLS for benign liver tumors.
- To analyze perioperative results of LLS in a single-center cohort.
- To determine the safety and efficacy of LLS for benign liver conditions.
Main Methods:
- Retrospective analysis of 445 LLS procedures.
- Focus on 100 cases of benign liver tumors.
- Review of tumor types, sizes, and perioperative outcomes.
Main Results:
- 100 benign liver tumors treated with LLS, including hepatocellular adenomas, biliary mucinous neoplasms, and focal nodular hyperplasia.
- Mean tumor size was 7.6 cm.
- Overall morbidity rate was 19%, with 9% severe complications (Clavien-Dindo grades 3-4); no mortality.
Conclusions:
- LLS for benign liver tumors demonstrates safety and excellent results.
- Careful patient selection is crucial, avoiding LLS solely for its minimally invasive nature.
- Indications for resection in benign liver tumors are becoming more selective.
