Laparoscopic Anatomical Versus Non-anatomical hepatectomy in the Treatment of Hepatocellular Carcinoma: A randomised controlled trial.
International journal of surgery (London, England)(2022)
Abstract
BACKGROUND:The choice of surgical modality for laparoscopic hepatectomy for hepatocellular carcinoma (HCC) has not been supported by high level of medical evidence hitherto. A prospective randomised controlled trial (RCT) was conducted to compare the perioperative and follow-up outcomes of patients with HCC treated by laparoscopic anatomical hepatectomy (LAH) and non-anatomical hepatectomy (LNAH).
METHODS:Between March 2013 and Jan 2018, eligible patients undergoing LAH and LNAH were enrolled and divided randomly into LAH group and LNAH group in this study. The perioperative and follow-up outcomes of both groups were compared and analysed.
RESULTS:A total of 385 patients with HCC were randomly divided into LAH (n = 192) and LNAH (n = 193) groups. The groups were evenly matched for age, sex, liver background, segment involvement, tumor size, Child-Pugh grade and preoperative liver function. The operative time in the LAH group was longer than that of the LNAH group (p = 0.003). No significant between-group differences in intraoperative blood loss (p = 0.368), transfusion rate (p = 0.876), conversion to laparotomy rate (p = 0.365), overall complication rates (p = 0.054) were observed. The 1-year, 3-year and 5-year overall survival rates (OS) in the LAH group were 91.1%, 67.2%, 43.2%, respectively. The corresponding data in the LNAH group were 89.1%, 63.7%, and 35.2%, respectively. No significant difference was observed with regard to the 5-year OS rate (p = 0.054) between the two groups. The 1-year, 3-year and 5-year disease-free survival (DFS) rates in the LAH group were 87.0%, 54.7%, 33.9%, respectively. The corresponding data in LNAH group were 70.5%, 34.7%, and 30.1%, respectively. The 5-year DFS rate in the LAH group was significantly higher than that in the LNAH group (p = 0.009).
CONCLUSIONS:LAH versus LNAH for selected HCC patients was associated with increased DFS, lower intrahepatic ipsilateral recurrence rate, comparable long-term OS and postoperative complications. LAH is therefore recommended for selected HCC patients.
