This trial was performed to compare short- and long-term outcomes after laparoscopic left-sided hepatectomy and open left-sided hepatectomy. Left-sided hepatectomy is a novel, minimally invasive operative technique for primary left-sided hepatolithiasis, but it has not been accepted widely due to the limited information about short- and long-term outcomes, effectiveness, and safety compared with the open approach.


Patients who underwent left-sided hepatectomy between January 2007 and December 2016 were reviewed and grouped into the open left-sided hepatectomy and left-sided hepatectomy groups, according to propensity score matching in terms of age, sex, body mass index, liver function, location of stone, hepatitis serology, and comorbidity on a ratio of 1:1.


No significant differences were observed in the demographic characteristics of the 200 patients included in the study. For the left-sided hepatectomy group (100 patients) when compared to the open left-sided hepatectomy group (100 patients, the duration of hospital stay was less (10.3 vs 14.7 days, P < .001), the incidence of postoperative biliary fistulas (5% vs 14%, P = .003) and overall morbidity were less (25% vs 45%, P = .003), out of bed return to activity was expedited (2.0 vs 2.7 days, P < .001), and the rate of stone recurrence in the long-term follow-up was les (5.1% vs 17%, P = .003).


Left-sided hepatectomy was associated with significantly lesser rate of stone recurrence, a shorter hospital stay, decreased morbidity and clinical biliary fistula rate, and expedited postoperative recovery compared with open left-sided hepatectomy.
