Results of major hepatectomy without vascular clamping using radiofrequency-assisted technique compared with total vascular exclusion.

Background/aims: To improve major hepatectomy results, various techniques with or without vascular clamping have been developed. We report the results of major hepatectomies performed with radiofrequency-assisted technique (RF) without vascular clamping and compare these results to total vascular exclusion (TVE).

Methodology: All patients who underwent a major hepatectomy between 1994 and 2004 were identified.

Early results after radiofrequency-assisted liver resection.

Aims And Background: Intraoperative blood loss during liver resection remains a major concern due to its association with higher postoperative complications and shorter long-term survival. The aim of this study was to assess the feasibility and safety of a novel concept for liver resection using a radiofrequency energy-assisted technique.

Methods: From January 2001 to July 2002, 42 patients were operated on using radiofrequency energy-assisted liver resection.
