Objective:To study the efficacy of laparoscopic limited anatomical hepatectomy (LLAH) for hepatocellular carcinoma (HCC) within the right anterior section.Methods:The clinical data of 144 patients with HCC confined in the right anterior section undergoing hepatectomy at the First Affiliated Hospital of Army Medical University from January 2015 to December 2022 were retrospectively analyzed, including 122 males and 22 females, aged (54.5±9.7) years. Patients were divided into LLAH ( n=27), laparoscopic anatomical hepatectomy (LAH, n=69), and laparoscopic non-anatomical hepatectomy (LNAH, n=48). Propensity score matching was used to compare the operative time, postoperative hospital stay, postoperative complications, serum total bilirubin and albumin, and the prognostic indicators such as tumor-free survival (DFS) rate and cumulative survival rate between the groups. Results:After propensity score matching, there were 26 cases each in LLAH and LNAH group. There was no significant difference in operative time, intraoperative blood loss and postoperative hospital stay between LLAH group and LNAH group (all P<0.05). The total bilirubin and albumin in LLAH on the third day after operation were [ M( Q1, Q3)] 24.1(20.9, 29.1) μmol/L and (35.8±2.9) g/L, better than those in LNAH group 39.3(33.2, 57.0) μmol/L and (33.9±2.5) g/L, respectively. The 1- and 3-year DFS rates in LLAH group were 92.3% and 57.7%, higher than those in LNAH group (80.8% and 19.2%) (all P<0.05). After propensity score matching, there were 25 patients each in LLAH and LAH group. The operative time, postoperative hospital stay and postoperative complications of LLAH group were lower than those of LAH group, and the liver function parameters of LLAH group was also better than those of LAH group (all P<0.05). There was no significant difference in DSF rate between the two groups LLAH group and LAH group ( χ2=0.10, P=0.800). Conclusions:The perioperative outcome of LLAH for HCC within the right anterior section are similar to that of LNAH and better than that of LAH. The DFS of LLAH were better than that of LNAH and similar to that of LAH.

Objective:To study the use of laparoscopic hepatic vein guided anatomic hepatectomy in the treatment of hepatocellular carcinoma.Methods:The clinical and follow-up data of 62 patients who underwent laparoscopic anatomic hepatectomy at the Department of Hepatobiliary Surgery of Southwest Hospital of the Army Medical University from January 2015 to February 2018 and met the inclusion criteria of the study were retrospectively analyzed. The operation procedure as to whether the main hepatic vein was exposed or not was determined. The patients were divided into the hepatic vein-oriented hepatectomy (HVOH) group when the main hepatic vein was exposed, and the traditional anatomic hepatectomy (TAH) group when the main hepatic vein was not shown. The perioperative and follow-up data of the two methods were compared.Results:A total of 31 cases were included in the HVOH group, there were 28 males and 3 females, age ranged from 29.0-70.0 (49.9±11.2) years. A total of 31 cases were included in the TAH group, there were 27 males and 4 females, age ranged from 22.0-73.0 (51.4±12.1) years. There were no significant differences in operation time, intraoperative blood loss, postoperative hospital stay, intraoperative conversion to open, and perioperative blood transfusion rates between the two groups ( P>0.05). The incidence of postoperative complication was significantly lower in the HVOH group than in the TAH group [9.7% (3/31) vs. 32.2% (10/31)] ( P<0.05), but no serious complications occurred (Clavein Level IV) in this study. The one-year tumor-free survival rate in the HVOH group was significantly higher than that in the TAH group (77.4% vs. 51.6%), ( P<0.05). There were no significant differences in the 1- and 3-year overall survival rates and tumor-free survival rates between the two groups ( P>0.05). Conclusion:Laparoscopic hepatic vein-guided anatomic hepatectomy for hepatocellular carcinoma had the potential advantages in reducing the perioperative complication rate, and enhanced the early tumor-free survival rates.
