Abstract
Laparoscopic liver resection has not yet gained wide acceptance among hepatic surgeons, mainly because of the difficulties encountered in dealing with possible intraoperative bleeding. A new technique of laparoscopic liver resection is presented. A 43-year-old man with a large and symptomatic hemangioma underwent a laparoscopic radiofrequency energy-assisted liver resection. After induction of pneumoperitoneum, four trocars were introduced and intraoperative ultrasonography and coagulative desiccation were performed along a plane of tissue 1 cm away from the edge of the lesion using the Cool-Tip radiofrequency probe and a 500-kHz, radiofrequency generator. The necrosed band of parenchyma then was divided and the specimen removed. The operative time was 300 min with a resection time of 240 min. The intraoperative blood loss was 75 ml. The postoperative course was uneventful and the patient was discharged on postoperative day 6. Laparoscopic radiofrequency-assisted liver resection is feasible, and with greater experience may contribute to the wider use of mini-invasive video-assisted liver surgery.
