Clinical efficacy of laparoscopic anatomical right posterior sector combined with anterior-dorsal segment resection for hepatocellular carcinoma / 中华消化外科杂志

ABSTRACT

Objective:To investigate the clinical efficacy of laparoscopic anatomical right posterior sector combined with anterior-dorsal segment resection for hepatocellular carcinoma.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 15 patients with hepatocellular carcinoma who underwent laparoscopic anatomical right posterior sector combined with anterior-dorsal segment resection in the Sun Yat-sen Memorial Hospital of Sun Yat-sen University from September 2020 to August 2021 were collected. There were 9 males and 6 females, aged 66(range, 35?77)years. Observation indicators (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination and telephone interview to detect tumor recurrence and survival of patients in the postoperative 90 days. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations. All the 15 patients underwent laparoscopic anatomical right posterior sector combined with anterior-dorsal segment resection successfully, without blood transfusion and conversion to laparotomy during the operation. The operation time, volume of intraoperative blood loss and occlusion time of first porta hepatis of the 15 patients were (155±17)minutes, (254±66)mL and (51±7)minutes, respectively. (2) Postoperative situations. The duration of postoperative hospital stay of the 15 patients was (7.4±2.1)days. Results of postoperative histopathological examination showed hepatocellular carcinoma and R 0 margins in all the 15 patients with a minimum distance from margin to tumor of (1.5±0.8)cm. There was none of the 15 patients transferred to intensive care unit, perioperative death or rehospitalization within 30 days after surgery. Of the 15 patients, 2 cases had postoperative complications, including 1 case with biliary fistula (grade Ⅰ of Clavien-Dindo classification) and 1 case with ascites (grade Ⅱ of Clavien-Dindo classification). Patients with complications were improved after washing and drainage, abdominal puncture and drainage. (3) Follow-up. All the 15 patients were followed up for the postoperative 90 days and none of them had tumor recurrence or death within postoperative 90 days. Conclusion:The laparoscopic anatomical right posterior sector and anterior-dorsal segment resec-tion for hepatocellular carcinoma is safe and feasible.
