    Journal: J Gastrointest Surg; 2021 Oct; 25(10):2718-2719. PubMed ID: 34357530.
    Abstract:
    BACKGROUND: The use of laparoscopic liver resection (LLR) is widespread owing to its several advantages, especially smaller incision (Kaneko et al., Ann Gastroenterol Surg 1:33-43, 1; Ciria et al., Surg Endosc 34:349-360, 2). However, both posterior sectionectomy and donor hepatectomy are extremely difficult procedures to perform in LLR (Hasegawa et al., Ann Gastroenterol Surg 2:376-382, 3; Soubrane and Kwon, J Hepatobiliary Pancreat Sci 24:E1-E5, 4; Takahara et al., Transplantation 101:1628-1636, 5; Lee et al., Clin Transplant 33:e13683, 6; Hong et al., Surg Endosc 33:3741-3748, 7; Rhu et al., J Hepatobiliary Pancreat Sci 27:16-25, 8). Moreover, the right posterior section graft procurement is also difficult even in open laparotomy procedure (Sugawara et al., Transplantation 73:111-114, 9; Hwang et al., Liver Transpl 10:1150-1155, 10; Hori, Kirino, and Uemoto, Hepatol Res 45:1076-1082, 11; Kusakabe et al., Liver Transpl 26:299-303, 12). The pure laparoscopic donor posterior sectionectomy has not been reported yet. Therefore, we aimed to introduce a novel procedure through a video clip. METHODS: The donor was placed in the semi-left lateral decubitus position with the reverse Trendelenburg position using a bean bag device. The right liver was mobilized, and the right hepatic vein was exposed. To adopt the liver hanging maneuver, a tape was inserted between the middle and right hepatic veins along the inferior vena cava. The posterior Glissonean pedicle was encircled and controlled, and the liver parenchyma was completely transected using the liver hanging maneuver. The vessels to the posterior section were respectively isolated. The posterior branches of the hepatic duct, hepatic artery, and portal vein were cut. The right hepatic vein was divided, and the graft liver was retrieved via a suprapubic incision. This study was approved by institutional ethics board (No. MH2019-119), and informed consent was taken from the patient. RESULTS: The overall surgical time was 503 min, and the blood loss was 400 mL. No complications were observed, and the donor was discharged from the hospital on postoperative day 11. CONCLUSION: This is the first report of pure laparoscopic donor hepatectomy of the posterior section graft. This procedure is more difficult than other laparoscopic donor hepatectomies because it involves parenchymal transection in the right intersectional plane and dissection of the posterior branches of hilar vessels.
