Right anatomical hepatectomy using extrahepatic glissonean pedicle approach combined liver hanging for hepatocellular carcinoma: surgical approach in a developing country.

ABSTRACT

Backgrounds/aims: To evaluate the outcomes of hepatocellular carcinoma (HCC) patients who underwent right anatomical hepatectomy using the combination of the extrahepatic Glissonean pedicle approach (Takasaki's technique) and liver hanging maneuver (LHM) (Belghiti's technique). Patients and methods: A retrospective analysis of 30 cases of HCC treated with right hepatectomy using extrahepatic Glissonean pedicle approach and LHM by only one surgeon at our department from March 2020 to August 2023. Clinical characteristics, pathological results, postoperative outcomes, and survival rate were analyzed. Results: Among the 30 HCC patients analyzed, males accounted for 96.7% of patients. The mean age was 54.9±11 years. 96.7% had normal preoperative liver function (Child-Pugh A). LHM with an extrahepatic Glissonean approach was feasible in 100% of cases with minor blood loss, no blood transfusion, intraoperative complications, or perioperative mortality. The mean operative time was 123.8±29.0 min. The mean hospital stay was 9.37±4.02 days. Postoperative liver failure accounted for 6.7%. Pathological results: 63.3% moderately differentiated HCC; 36.7% poorly differentiated HCC. 1-year, 2-year, and 3-year survival rates were 86.1, 73.8, and 59.0%, respectively. Recurrence was witnessed in 13 (43.3%) cases, with 6 (20%) cases in remnant liver. 1-year, 2-year, and 3-year disease-free survival were 69.3, 42.0, and 28.0%, respectively. Conclusion: Right anatomical hepatectomy using extrahepatic Glissonean pedicle approach combined LHM for HCC was feasible and safe at our high-volume oncology center in a developing country.
