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. Radiofrequency energy was applied along the resection edge to create a 'zone of desiccation' prior to resection with a scalpel.

Results: Median resection time was 50 mins (range, 30-110). The median blood loss during resection was 30 mL (range, 15-992). Mean preoperative and postoperative hemoglobin values were 13.7 g/dL (SD +/- 1.6) and 11.8 g/dL (SD +/- 1.4), respectively. No blood transfusion was registered, nor was any mortality observed. There were 3 postoperative complications, one subphrenic abscess, one chest infection and one biliary leak from a hepatico-jejunostomy. Median postoperative stay was 8 days (range, 5-86).

Conclusions: Liver resection assisted by radiofrequency energy is feasible, easy and safe. This novel technique offers a new method for 'transfusion-free' resection without the need for sutures, ties, staples, tissue glue or admission to an intensive care unit.
