Abstract

Background: Selective hemihepatic vascular occlusion is utilized in both right and left hemihepatectomies to preserve blood supply to the intact lobe, maintain hemodynamic stability, and mitigate surgical risks. While this technique encompasses both intrathecal and extrathecal Glissonean pedicle transection methods, there is a lack of systematic comparative reports on these two approaches.

Aim: To retrospectively analyze the clinical data of patients with hepatocellular carcinoma (HCC) undergoing laparoscopic anatomical hepatectomy in our hospital to explore the feasibility, safety, and short- and long-term efficacy of extrathecal and intrathecal Glissonean pedicle transection methods in laparoscopic left hemihepatectomy.

Methods: A retrospective study was performed to analyze the clinical data of 49 HCC patients who underwent laparoscopic left hemihepatectomy from January 2019 to December 2022 in our hospital. These patients were divided into extrathecal Glissonean pedicle transection (EGP) group ( = 24) and intrathecal Glissonean pedicle transection (IGP) group ( = 25) according to the different approaches used for selective hemihepatic vascular occlusion. The perioperative indicators, liver function indexes, complications, and follow-up findings were compared between these two groups.

Results: The surgeries were smooth in both groups, and no perioperative death was noted. The hepatic pedicle transection time and the operation time were (16.1 ± 2.3) minutes and (129.6 ± 19.0) minutes, respectively, in the EGP group, which were significantly shorter than those in the IGP group [(25.5 ± 2.4) minutes and (184.8 ± 26.0) minutes, respectively], both < 0.01. There were no significant differences in intraoperative blood loss, time to anal exhaust, hospital stay, drain indwelling time, and postoperative liver function between the two groups (all > 0.05). The incidence of postoperative complications showed no significant difference [16.67% (4/24) 16.0% (4/25), > 0.05). All the 49 HCC patients were followed up after surgery (range: 11.2-53.3 months; median: 36.4 months). The overall survival rate and disease-free survival rate were not significantly different (both > 0.05).

Conclusion: Both extrathecal and intrathecal Glissonean pedicle approaches are effective and safe hepatic inflow occlusion techniques in laparoscopic left hemihepatectomy for HCC. However, the extrathecal approach simplifies the hepatic pedicle transection, shortens the operation time, and increases the surgical efficiency, making it a more feasible technique.
