Early experience employing a linear hepatic parenchyma coagulation device.

Background: In recent years, hepatic resection for primary and metastatic disease has been facilitated by improved anesthetic and surgical techniques, as well as by the application of new technologies. Historically, the major complications associated with hepatic resection have been postoperative bleeding, bile leak, and liver failure. Resection techniques and devices that minimize hemorrhage and bile leak, and enable the preservation of functional hepatic parenchyma, have been useful in the surgical management of liver tumors.

Methods: Herein, the use of a radiofrequency powered device for the pretransection coagulation of hepatic tissue that simultaneously seals blood vessels and bile ducts 3 mm in diameter or smaller is described.

Results: Early results from our single-center experience with the use of this linear radiofrequency device are reported. Seven patients underwent liver resection for either hepatocellular carcinoma or colorectal cancer metastases. There were no postoperative bile leaks, hemorrhage, or hepatic insufficiency. No transfusions were required, and the mean estimated blood loss for the parenchymal transection phase was less than 165 cc.

Conclusions: The linear radiofrequency device is expedient for the pretransection coagulation of hepatic tissue and, thus, facilitates liver resection.
