OBJECTIVE: The Glissonean pedicle transection method of liver resection has been found to shorten operative time and minimize intraoperative bleeding during liver segmentectomy. We have compared the feasibility, effectiveness, and safety of the Glissonean pedicle transection method with the Pringle maneuver in patients undergoing selective curative resection of large hepatocellualr carcinoma (HCC).

METHODS: Eligible patients with large (> 5 cm) nodular HCC (n = 50) were assigned to undergo curative hepatectomy using the Glissonean pedicle transection method (n = 25) or the Pringle maneuver (n = 25). Partial interruption of the infrahepatic inferior vena cava was incorporated to further reduce bleeding from liver transection. The primary outcome measure was postoperative changes in liver function from baseline. Secondary outcomes included operating time, volume of intraoperative blood loss/transfusion, and time to resolution of ascites.

RESULTS: The two groups were comparable in age, sex, site and size of the liver tumor, segment or lobe intended to be resected, and liver function reserve, and the results were not significant statistically. All patients underwent successful major hepatectomies using the assigned method, with the extent of major hepatectomy comparable in the two groups (P = 0.832). The Glissonean approach was associated with shorter hepatic inflow interruption (30.0 ± 12.0 min vs. 45.0 ± 13.0 min, P < 0.001), lower volume of blood loss (145.0 ± 20.0 mL vs. 298.0 ± 109.0 mL, P < 0.001), reduced requirement for transfusion (0.0 ± 0.0 mL vs. 200.0 ± 109.0 mL, P < 0.0001), and more rapid resolution of ascites (9.5 ± 1.2 d vs. 15.3 ± 2.4 d, P < 0.001). Postoperative liver function measures were comparable in the two groups, and the results were not significant statistically.

CONCLUSION: The Glissonean pedicle transection method is a feasible, effective, and safe technique for hepatic inflow control during the curative resection of large nodular HCCs.
