RESUMO
The clinical data were retrospectively analyzed for 21 cases of liver neoplasms undergoing laparoscopic hepatectomy from December 2007 to October 2012.Among 11 cases of borderline hepatocellular carcinoma (HCC) (1.0-9.0 cm),6 of them were of micro hepatocellular carcinoma (MHCC) with a diameter ≤2 cm.There were 10 cases of borderline hepatic benign tumor,including liver hemangioma (n =7),hepatic adenoma (n =1),liver lymphoma (n =1) and liver focal necrosis (n =1).According to Couinaud's liver segmentation method,neoplasm was located on segment Ⅲ (n =13),segment Ⅳ (n =6),segment Ⅴ (n =1) and segment Ⅵ (n =1).Laparoscopic hepatectomy was successful in all patients.There was neither conversion into open approach nor postoperative complications of bile leakage,air embolism or perioperative mortality,etc.The mean operative duration was (120 ± 30) minutes,average hemorrhagic volume (165-±79) ml and normal diet & ambulation at Day 1-2 post-operation.The average postoperative hospitalization stay was (16 ± 10)days and l-year survival rate 100%.The parameters of leucocyte,liver enzymes,albumin and bilirubin returned to normal at Week 1 post-operation.Once a reasonable surgical indication is selected,laparoscopic resection is both safe and effective for peripheral micro hepatocellular carcinoma.
