Safe Strategy to Initiate Total Laparoscopic Donor Right Hepatectomy: A Stepwise Approach From a Laparoscopy‐Assisted Method

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
