Abstract

Purpose
We aimed to compare the operative outcomes of laparoscopic right posterior sectionectomy (RPS) and open RPS and evaluate the feasibility of laparoscopic RPS.
Methods
From January 2009 to December 2017, laparoscopic liver resections were performed in 235 patients at Chonnam National University Hwasun Hospital, South Korea. We retrospectively analyzed the clinical data of 16 patients who underwent laparoscopic RPS and compared the outcomes with those who underwent open RPS (n=17).
Results
The laparoscopic group had a mean tumor size of 3.82±1.73 cm (open group [OG]; 4.18±2.07 cm, p=0.596), mean tumor-free margin of 10.44±9.69 mm (OG; 10.06±10.62 mm, p=0.657), mean operation time of 412.2±102.2 min (OG; 275.0±60.5, p<0.001), mean estimated blood loss of 339.4±248.3 ml (OG; 236.4±102.7 ml, p=0.631), mean postoperative hospital stay of 11.63±2.58 days (OG; 14.71±4.69 days, p=0.027), and mean postoperative peaks of aspartate aminotransferase, alanine aminotransferase, total bilirubin, and prothrombin time of 545 mg/dl, 538 mg/dl, 1.39 mg/dl, 1.41 international normalized ratio (OG; 237 (p<0.001), 216 (p<0.001), 1.52 (p=0.817), and 1.45 (p=0.468)), respectively. There were no deaths or major complications in ether group. There were no cases of open conversion. Laparoscopic RPS was associated with a shorter hospital stay, prolonged operation time and lower complication rate. With long-term prognosis, no difference was found in overall survival rate and disease-free survival rate between the two groups.
Conclusion
Laparoscopic RPS can be performed, but the problems of long operative time and decrease in liver function should be resolved.
