Abstract

Background

The use of single-port laparoscopy for left-lateral liver sectionectomy (LLLS) has been reported in the literature, but the effectiveness and safety of LLLS has not been validated in randomized, controlled trials. This prospective randomized controlled trial compared the effectiveness and safety of single-port and multi-port laparoscopic LLLS for the surgical treatment of benign liver disease.

Methods

Altogether, 38 patients aged 17–65 years (16 men, 22 women) with benign liver diseases were hospitalized for elective laparoscopic LLLS between January 2010 and December 2012. Patients were randomly assigned to either single-port (n = 19) or multi-port (n = 19) laparoscopic LLLS. Main outcome measures were operative time, volume of intraoperative blood loss, complication rates, and postoperative hospitalization.

Results

Baseline characteristics of the two groups were comparable. Single-port and multi-port laparoscopies were successfully completed in all but one patient (1/19, 5.3 %) who required conversion from a single-port to a multi-port procedure. The two groups had similar mean operative times and volumes of intraoperative blood loss. There were no clinically significant postoperative complications or deaths. The single-port group had a significantly shorter postoperative hospitalization than the multi-port group (2.5 ± 1.7 vs. 4.0 ± 2.1 days; p < 0.05).

Conclusions

Single-port laparoscopic LLLS is a technically feasible, effective, safe alternative to multi-port laparoscopy for the treatment of benign liver diseases in cautiously selected patients.
