Abstract

Background: Living donor liver transplantation (LDLT) is the final treatment for children with end-stage liver disease. Congenital biliary atresia (CBA) is the most common disease requiring LDLT in Japan, and a left lateral sector graft is preferably procured owing to its anatomic predictivity and identical graft volume for preschool recipients. Laparoscopic left lateral sectionectomy (L-LLS) for LDLT has been recently established; however, there is no report about the innovative technique in L-LLS. The aim of this study was to introduce our L-LLS using the Glissonean approach and bridging technique for pediatric LDLT. Materials and Methods: From September 2017 to September 2020, 5 cases of L-LLS for pediatric LDLT because of CBA were performed and we performed L-LLS using the original technique on their donors. In this novel procedure, the left Glissonean pedicle was encircled at the parenchymal side of the Laennec capsule after mobilization of the lateral sector and visualization of the left hepatic vein. Then, we passed 2 tapes through the encircled Glissonean pedicle at the hepatic side and the duodenal side, as the caudate lobe branch is enclosed like a bridge. By virtue of this bridging technique, we encircled the caudate lobe branch alone by switching the tape, and we clipped and divided it; this technique secured an adequately long hepatic duct on the graft side to perform a hepaticojejunostomy. The left hepatic duct was divided after indocyanine green fluorescence cholangiography, and the left hepatic artery and portal vein were divided as well. Finally, the left hepatic vein was transected and procured from an extended intraumbilical incision. Results: We achieved L-LLS by using the Glissonean approach and the bridging technique in the 5 donors. The median operating time and blood loss were 282 (268 to 332) minutes and 34 (25 to 75) mL, respectively. There was no conversion to hybrid or open LLS and no postoperative complications. Regarding recipient outcomes, hepatic artery thrombosis occurred on postoperative day 4 in a 5-year-old female. All grafts function well and all recipients are alive after discharge (range of observation period, 3 to 26 mo). Conclusions: We herein present standardized L-LLS using the Glissonean approach and bridging technique for pediatric LDLT. Our technique can secure a longer margin of the left hepatic duct for recipients' hepaticojejunotomy. Our results have demonstrated the advantage in pediatric LDLT, especially in patients with CBA after the Kasai procedure.
