Regarding the different types of tumor resection (only bile duct resection or right/left hemihepatectomy; exploratory laparotomy due to unresectable disease excluded), no significant differences in survival were observed among the three groups.
It was suggested that, if the depth of invasion of GBC to the liver is >2 cm, and lymph node metastases in the rear of the pancreas head (13th groups) invade the descending duodenum, but without metastasis of the abdominal aorta and mesenteric lymph nodes, HPD is feasible on the premise that R0 resection may be achieved by hemihepatectomy or enlarged hemihepatectomy combined with PD.
The most frequent indications for laparoscopic liver resection are lesions in segments II-VI, especially for wedge resection, segmentectomy or lateral left-side hemihepatectomy. Liver segments I, VII, and VIII are traditionally considered inaccessible for laparoscopic approach due to their anatomical position in relation to the other structures.
