Laparoscopic extended major hepatectomy (LEMH) is feasible but associated with higher morbidity. Outcomes are manageable in high-volume centers, necessitating experienced surgeons for these complex liver surgeries.
Area of Science:
- Hepatobiliary Surgery
- Minimally Invasive Surgery
- Surgical Oncology
Background:
- Laparoscopic major hepatectomy (LMH) is increasingly adopted in specialized centers.
- Limited data exists on laparoscopic extended major hepatectomies (LEMH) and their outcomes.
- This study aims to compare LEMH with standard LMH.
Purpose of the Study:
- To compare perioperative characteristics and postoperative outcomes of LEMH versus standard LMH.
- To evaluate the feasibility and safety of LEMH.
Main Methods:
- Retrospective analysis of prospectively collected data from 195 patients undergoing purely laparoscopic anatomical hepatectomy or trisectionectomy (February 1998 - January 2016).
- Patients were divided into LEMH (n=47) and standard LMH (n=148) groups.
- Perioperative and postoperative outcomes were compared between the two groups.
Main Results:
- LEMH represented 24.1% of LMH cases, primarily for colorectal liver metastases.
- LEMH had higher blood loss (400 vs. 214 ml) but similar transfusion requirements and liver failure rates.
- Overall morbidity was higher in LEMH (60% vs. 41.5%), with increased biliary leakage and pulmonary complications in left LEMH.
- Postoperative mortality was comparable (5% in LEMH vs. 2.5% in LMH).
Conclusions:
- Laparoscopic extended major hepatectomy (LEMH) is feasible, demonstrating manageable outcomes.
- LEMH is associated with significant morbidity, including higher rates of complications.
- These complex procedures necessitate high-volume centers and experienced surgical teams for successful implementation.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
