CRITICAL EVALUATION OF LONG-TERM RESULTS OF MALIGNANT HEPATIC TUMORS TREATED BY MEANS CURATIVE LAPAROSCOPIC HEPATECTOMY

摘要

ABSTRACT Background: Laparoscopic hepatectomy has presented great importance for treating malignant hepatic lesions. Aim: To evaluate its impact in relation to overall survival or disease free of the patients operated due different hepatic malignant tumors. Methods: Thirty-four laparoscopic hepatectomies were performed in 31 patients with malignant neoplasm. Patients were distributed as: Group 1 - colorectal metastases (n=14); Group 2 - hepatocellular carcinoma (n=8); and Group 3 - non-colorectal metastases and intrahepatic cholangiocarcinoma (n=9). The conversion rate, morbidity, mortality and tumor recurrence were also evaluated. Results: Conversion to open surgery was 6%; morbidity 22%; postoperative mortality 3%. There was tumor recurrence in 11 cases. Medians of overall survival and disease free survival were respectively 60 and 46 m; however, there was no difference among studied groups (p>0,05). Conclusion: Long-term outcomes of laparoscopic hepatectomy for treating hepatic malignant tumors are satisfactory. There is no statistical difference in relation of both overall and disease free survival among different groups of hepatic neoplasms.
