Laparoscopic versus open right posterior sectionectomy: an international, multicenter, propensity score-matched...

Area of Science:

• Hepatobiliary Surgery
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Laparoscopic liver resection is standard for minor procedures.
• Evidence for complex resections like right posterior sectionectomy (RPS) is limited.

Purpose of the Study:

• Compare surgical outcomes of laparoscopic right posterior sectionectomy (LRPS) versus open right posterior sectionectomy (ORPS).

Main Methods:

• International multicenter retrospective study (2007-2018).
• Propensity score matching (1:1 ratio) of 150 LRPS and 150 ORPS patients.
• Primary endpoint: Major complication rate (Accordion grade ≥3). Secondary endpoints: blood loss, length of hospital stay (LOS), resection status.

Main Results:

• LRPS associated with shorter operative time, less blood loss, and shorter LOS.
• No significant difference in major complication rates or R0 resection rates between LRPS and ORPS.
• Open approach and malignancy were risk factors for increased blood loss and LOS.

Conclusions:

• LRPS offers advantages in operative time, blood loss, and LOS for selected patients undergoing right posterior sectionectomy.
• LRPS demonstrates comparable safety and oncologic outcomes to ORPS.
