The clinical data of 97 patients who underwent laparoscopic hepatectomy from July 2007 to November 2014 in the First Affiliated Hospital of Wenzhou Medical University was collected.Of the 97 patients,46 cases were diagnosed with hepatolithiasis,20 with primary liver cancer,26 with benign liver tumor,1 with liver abscess,and 4 with metastatic liver cancer.The surgical approaches included laparoscopic left hepatectomy (n =16),left lateral lobectomy (n =35),right hepatectomy (n =2),right posterior lobectomy (n =1),hepatic wedge resection (n =42),and left lateral lobectomy with segment Ⅶ resection (n =1),and 4 cases underwent multi-visceral resection.88 patients underwent laparoscopic hepatectomy and 9 patients were transferred to open hepatectomy.Postoperative complications included bile leakage (n =9),abdominal cavity infection (n =7),ascites (n =1),wound infection (n =1),pleural effusion (n =3) and pulmonary infection (n =1).There was no perioperative death.Taken together,laparoscopic hepatectomy is feasible and efficient for treating liver diseases and it has the advantages of minimal invasion and rapid recovery.

Objective To analyze risk factor of bile duct injury (BDI) during laparoscopic cholecystectomy (LC). Methods A retrospective population-based cohort study was carried out on 13878 patients undergoing LC from Apr 1994 to Dec 2003. Patients were divided into BDI group and non-BDI group. Factors with statistically significant differences between groups in anivariable analysis were selected to construct a multivariate logistic regression mode. Result Among 13878 LC procedures 38 BDI (0.27%) were identified. Factors which were of significant differences between groups in anivariable analysis includ diameter of common bile duct(?~2=5.92, P
