ABSTRACT
BACKGROUND/AIMS:
Microwave ablation is the most recent development in the field of tumor ablation and is a well established and safe local ablative method available for liver tumors (both primary and secondary tumors). The technique allows for flexible approaches to treatment, including percutaneous, laparoscopic, and open surgical access. Laparoscopic technique has the advantages of accurate tumor staging, better tolerability and low cost. It can be performed in tumors which are close to the vital organs. The aim of this study was to evaluate the feasibility and safety of laparoscopic microwave ablation of liver tumors.METHODOLOGY:
During January 2001 to December 2005, 57 patients with liver tumors were treated with laparoscopic microwave ablation in the department of Surgical Oncology. There were 34 male and 23 female patients. Out of 57 patients, 11 patients had hepatocellular carcinoma and 46 patients had secondaries in the liver. The most common source of secondaries was colorectal cancers. Laparoscopic microwave ablation of tumors was performed in these patients.RESULTS:
During the study period, 57 patients with no evidence of extrahepatic disease underwent laparoscopic microwave ablation of unresectable hepatic tumors. No major intraoperative complications occurred. Postoperatively all the patients did well. Four patients developed liver abscess at the ablation area. Two patients required percutaneous aspiration of the liver abscess. No other major complications occurred. Follow-up CT scan shows complete necrosis of the tumors. Patients were followed-up at regular intervals.CONCLUSIONS:
Laparoscopic microwave ablation is a feasible and safe alternative to open microwave ablation of the liver tumors. It carries all the advantage of minimal invasive surgery. In experienced hands, microwave ablation using laparoscopic technique can be done safely and effectively.
