Objective:To study the feasibility, safety and technique for laparoscopic anatomical liver resection of segment 8.Methods:The clinical data of 9 patients who underwent laparoscopic anatomical liver resection of segment 8 from January 2015 to December 2019 at Hunan Provincial People's Hospital were retrospectively analyzed. There were 6 males and 3 females, with age ranging from 29 to 67 years (average 53.6 years). The operation time, intraoperative blood loss , postoperative hospital stay, postoperative complications, and long-term survival and recurrence rates on follow-up were analysed.Results:Laparoscopic anatomical liver resection of segment 8 was successfully carried out in these patients. The mean operative time was 188.9 min(range 140-240 min). The mean estimated intraoperative blood loss was 117.8 ml (range 20-300 ml). The postoperative hospital stay was 6.9 days (range 3-12 days). One patient developed pleural effusion after operation and responded to conservative treatment. Another patients developed ascites with delayed extubation. The patient was successfully treated with conservative treatment. No patients developed complications above Clavien Dindo Ⅲa. There were no perioperative deaths. The postoperative pathological results showed hepatocellular adenoma ( n=2), hepatocellular carcinoma ( n=4), cholangiocarcinoma ( n=1), and metastatic liver cancer ( n=2). On follow-up for 12-58 months (median 22 months) one patient with hepatocellular carcinoma developed recurrence at 18 months after operation and was treated with microwave ablation. The other patients were well on follow-up. Conclusions:With adequate preoperative evaluation, reasonable case selection, rigorous surgical planning, and skilled laparoscopic techniques, laparoscopic anatomical liver resection of segment 8 was safe and feasible, and the short-term efficacy was good in this study.
