Use of microwave tissue coagulator in hepatocellular carcinoma resection: compared with Lin's hepatic clamp.
Fifty-nine patients with hepatocellular carcinoma (HCC) underwent resection with the aid of a microwave tissue coagulator at the Department of Surgery, National Taiwan University Hospital from July 1987 to December 1992. There were 41 men and 18 women with an average age of 59.2 years (range, 32-79 years). The intraoperative blood transfusion included packed RBC 1.53 +/- 1.34 U, fresh frozen plasma 3.85 +/- 1.69 U and/or platelet 1.58 +/- 3.07 U. The operation time from skin incision to skin closure was 250 +/- 74.9 minutes (range, 125 range, 495 minutes) and the average hospital stay was 20 +/- 9.7 days (nine to 50 days, median 17 days). The complication rate was 16.9% (10/59), including two with biliary fistula, prolonged impaired liver function and pleural effusion. Subphrenic abscess was seen in one patient and ascites in three. There was no operative mortality. Compared to 34 patients who underwent similar hepatic resections for HCC carcinoma with the aid of Lin's hepatic clamp, there was no statistical difference between the operation time, and intraoperative blood transfusion. However, the hospital stay was shorter in the microwave group. The change in liver function was also less remarkable in the microwave group and the postoperative complication rate was lower. We conclude that the application of microwave tissue coagulator is useful and safe in the resection of HCC.
