Background A standardized laparoscopic right hepatectomy (LRH) approach named the caudal approach was recently reported. Yet, the value of this approach compared with state-of-the-art open right hepatectomy (ORH) remains unknown. The purpose of this study was therefore to compare the short-term outcomes of LRH using the caudal approach and ORH with anterior approach and liver hanging maneuver. Methods One-hundred eleven consecutive patients who underwent LRH with caudal approach were prospectively collected; 346 patients who underwent ORH with anterior approach and liver hanging maneuver were enrolled as a control group. Propensity score matching (PSM) of patients in a ratio of 1: 1 was conducted and the perioperative outcomes were compared. Results After PSM, two well-balanced groups of 72 patients each were analyzed and compared. The conversion rate in the LRH group was 18.1%. Perioperative blood loss and transfusion rates were significantly lower in the LRH group as compared to the ORH group (median, 200 ml vs. 500 ml, p < 0.001 and 9.9% vs. 26.8%, p = 0.009, respectively), while operation time was significantly longer (median, 348 min vs. 290 min, p < 0.001). Overall (26.4% vs. 48.6%, p = 0.006) and symptomatic pulmonary (6.9% vs. 19.4%, p = 0.027) complication rates were significantly lower in the LRH group. Hospital stay was significantly shorter in the LRH group (median, 8 days vs. 9 days, p = 0.013). Conclusions LRH using the caudal approach is associated with improved short-term outcomes compared to state-of-the-art ORH in patients qualifying for both approaches, and can be proposed as standard practice.
