- Abstract
The objective of this study was to assess the clinical impact of laparoscopic hepatectomy from technical and oncological viewpoints through the consecutive 5-year experience of an expert team. The subjects consisted of 491 consecutive hepatectomies performed over the course of 5 years. A total of 190 hepatectomies (38.6 %) were performed laparoscopically, and the remaining 301 (61.4 %) were open hepatectomies. Chronological trends of operative procedures and their indications were evaluated, and patients with hepatocellular carcinoma (HCC) were analyzed from an oncological viewpoint. The proportion of laparoscopic hepatectomies performed increased significantly during the study period (from 17.6 to 49.5 %). According to chronological trends, right hepatectomy was standardized using consecutive steps after minor hepatectomy, left lateral sectionectomy, and left hepatectomy were standardized. The proportion of laparoscopic hepatectomies performed for HCC increased from 21.4 to 71.0 %. No significant difference was observed in the proportion of major hepatectomies performed for HCC between the open and laparoscopy groups (50.6 vs. 48.6 %, p = 0.8053), whereas that of anatomical segmentectomy for HCC was significantly lower in the laparoscopy group (28.7 vs. 11.1 %, p = 0.0064). All laparoscopic anatomical segmentectomies were of segments 5 and 6, and there was no segmentectomy of posterosuperior lesions. The present study shows the consecutive technical developmental processes for minor hepatectomy, left lateral sectionectomy, left hepatectomy, and right hepatectomy without compromising oncological principles. Laparoscopic anatomical segmentectomy for posterosuperior lesions may be the most technically demanding procedure, requiring individualized standardization.
