Abstract

Laparoscopic major hepatectomy is a common procedure that has been reported frequently; however, laparoscopic resection of centrally located tumors involving segments 4, 5, and 8 remains a technically difficult procedure because it requires 2 transection planes and dissection of numerous branches of the hepatic vein and glissonean capsule compared to hemi-hepatectomy. Here, we present 7 cases of totally laparoscopic right anterior sectionectomy (Lap-RAS) and 3 cases of totally laparoscopic central bisectionectomy (Lap-CBS).Between May 2013 and January 2015, 10 totally laparoscopic anatomical resections of centrally located tumors were performed in our institution. The median age of the patients was 54.2 (38-72) years and the median ICG-R15 was 10.4 (3.9-17.4). There were 8 patients with hepatocellular carcinoma (HCC) and 2 with metastatic colorectal cancer. All the HCC patients has the liver function impairment on the degree of Child-Pugh score A.The mean operation time was 330 ± 92.7 minutes with an estimated blood loss of 325 ± 234.5 mL. Only 1 patient required transfusion during surgery. Mean postoperative hospital stay was 9.5 ± 3.4 day and postop complication was reported only 1 case that has the fluid collection at the resection margin of the liver. Mean resection margin was 8.5 ± 6.1 mm and tumor size was 2.9 ± 1.9 cm.Totally lap-RAS and lap-CBS are feasible operative procedures in patients with centrally located tumor of the liver and particularly in patients with limited liver function such as those with cirrhosis.
