Summary
Laparoscopic hepatectomy (Lap) offers significant benefits over open hepatectomy (Op), including reduced bleeding, fewer complications, and shorter hospital stays. This meta-analysis confirms Lap
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Procedures
- Surgical Outcomes Research
Background:
- Previous meta-analyses indicated advantages for laparoscopic hepatectomy (Lap) over open hepatectomy (Op) regarding bleeding and hospital stay.
- The evolution of surgical techniques necessitates ongoing evaluation of perioperative outcomes.
Purpose of the Study:
- To re-evaluate and compare perioperative variables and adverse outcomes between laparoscopic hepatectomy (Lap) and open hepatectomy (Op) performed after the year 2000.
Main Methods:
- A systematic literature search was conducted using PubMed and Ovid Medline to identify comparative clinical studies.
- Meta-analysis and power analysis were employed to assess the pooled data from selected studies comparing Lap versus Op.
Main Results:
- Laparoscopic hepatectomy (Lap) demonstrated significantly lower patient bleeding compared to open hepatectomy (Op).
- Lap was associated with a significantly lower incidence of complications and a shorter duration of hospital stay than Op.
- Operative time did not differ significantly between the two surgical approaches; however, some studies lacked sufficient statistical power for definitive conclusions.
Conclusions:
- Current evidence supports the clinical benefits of laparoscopic hepatectomy (Lap), including reduced complications and shorter hospital stays.
- While Lap shows clear advantages, the statistical power of some comparative studies remains a limitation in fully evaluating all outcomes.
