Use of radiofrequency hepatic parenchymal transection device in hepatic hemangioma resection: early experience and lessons learned

Abstract

Hepatic parenchymal transection with the Habib sealer device is a feasible approach to resect HH. Further study is needed to objectively compare the efficacy of RF-assisted parenchymal transection with that of traditional parenchymal transection techniques.

Techniques of radiofrequency-assisted precoagulation in laparoscopic liver resection

“…The group subsequently developed a bipolar device [12], and in their most recent series reported on 236 patients who underwent precoagulation with monopolar and bipolar RF devices, confirming the safety and efficacy of both devices [13]. Several other groups also have verified the efficacy of the devices for precoagulation in open hepatic resection [14][15][16][17][18].…”

Research and development of a new RF-assisted device for bloodless rapid transection of the liver: Computational modeling and in vivo experiments

“…Weber et al [ 12 ] pioneered the use of RF needle electrodes to obtain a 1 or 2 cm wide coagulation band on the resection line before employing the scalpel, thereby facilitating bloodless liver resection. Further applications of the concept of pre-coagulating tissue with RF energy prior to transection have recently been developed with devices like Habib4x [ 13 ] or InLine [ 14 - 18 ], in which a range of RF electrodes are inserted in a monopolar or bipolar configuration. Once the plane of coagulation has been created with these RF-assisted devices, the coagulated tissue is cut bloodlessly with a straight scalpel.…”
