ABSTRACT

Objective:To compare the efficacy of laparotomy and laparoscopic Glisson pedicle transecting segmental hepatectomy in the treatment of hepatocellular carcinoma.Methods:The clinical data of 138 patients with hepatocellular carcinoma who underwent Glisson pedicle transection hepatectomy in the Affiliated Hospital of Chengde Medical College from March 2012 to November 2015 were collected retrospectively. 45 patients underwent laparoscopic surgery (laparoscopic group) and 93 patients underwent laparotomy. 45 patients were selected as open group according to the most clinical ratio of propensity score. The baseline data, operation, stress index, liver function index and postoperative survival rate were compared between the two groups. COX proportional hazard regression model was used to analyze the influencing factors of 5-year prognosis. Normally distributed measurement data were expressed as mean±standard deviation ( Mean± SD), and independent sample t test was used for comparison between groups. The chi-square test was used to compare the enumeration data between groups. Results:The operation time, intraoperative blood loss, blood transfusion cases, complications, postoperative eating time, drainage tube removal time, and hospital stay in the laparoscopic group were (219.48±53.61) min, (208.53±39.74) mL, 2, 3, (3.62±0.51) d, (4.73±0.85) d, (10.59±1.37) d, the open group were (185.37±46.92) min, (267.49±35.83) mL, 8, 10, (4.56±0.73) d, (5.29±0.94) d, (13.87±1.68) d, the differences between the two groups were statistically significant ( P<0.05). Cortisol, norepinephrine, C-reactive protein, aspartate aminotransferase, alanine aminotransferase, total bilirubin in the postoperative laparoscopic group) And albumin levels were (258.39±30.76) ng/mL, (66.78±7.31) ng/mL, (28.39±3.45) μg/mL, (66.51±7.14) U/L, (73.39±7.85) U/L, (20.67±2.74) μmol/L, (37.52±6.48) g/L, the open group were (316.92±37.51) ng/mL, (75.63±8.39) ng/mL, (38.47±4.56) μg/mL, (82.39±9.06) U/L, (94.05±9.74) U/L, (22.93±3.18) μmol/L, (34.65±5.87) g/L, the differences between the two groups were statistically significant ( P<0.05). There were no statistically significant difference in overall survival rate and tumor-free survival rate between the laparotomy group and the laparoscopic group at 1, 3, and 5 years after surgery ( P>0.05). The COX proportional hazards regression model showed that HBsAg positive, Child-Pugh grade, alpha-fetoprotein, and tumor diameter were risk factors affecting the 5-year prognosis of patients ( HR=6.627, 7.518, 5.143, 4.881, 95% CI 1.516-9.738, 2.382-12.495, 3.078-6.249, 1.925-7.723, P<0.05). Conclusion:The long-term effects of laparotomy and laparoscopic Glisson pedicle transection hepatectomy are the same in selective hepatocellular carcinoma cases, but laparoscopic surgery can reduce intraoperative blood loss, blood transfusion cases and complications, facilitate early removal of drainage tube and food intake, shorten hospital stay, reduce stress reaction, and promote the recovery of liver function, so the short-term effect is better.
