LAUSR

Total laparoscopic donor right hepatectomy (TLDRH) for adult living liver donors has been reported by a few experienced centers, but with limited cases, its safety and feasibility remain controversial. We report our experience initiating TLDRH using a stepwise approach to gradually convert laparoscopy-assisted donor right hepatectomy (LADRH) to TLDRH. We retrospectively analyzed the data of 61 LADRHs, 56 conventional open donor right hepatectomies (CODRHs), and 3 TLDRHs performed between March 2014 and June 2018. There were no significant differences in perioperative outcomes between donors undergoing LADRH and CODRH, except for a slight elevations in the operative time (436.5 vs 392.9 min, p < 0.001) and the graft warm ischemic time (5.4 vs 4.0 min, p < 0.001) in the LADRH group. The recipients' posttransplant one-year survival rates in the LADRH and CODRH groups were also similar (93.2% and 94.6%, p = 0.384). For three donors in whom TLDRH was converted from LADRH in a stepwise manner, the average operative time and blood loss were 570 min and 316.7 ml, respectively. Donors were discharged on postoperative day 10 without any surgical complications. LADRH can be performed routinely on liver living donors. A stepwise approach could be adopted to “covert” suitable donors from LADRH to a total laparoscopic procedure to maximize donor safety. This strategy is reliable and could be reproduced in most LDLT centers.
