[Radiofrequency-assisted hepatic resection--first experience].
AIMS: Intra-operative 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 Radio-Frequency energy assisted technique. METHODS: From January 2001 to January 2002, 27 patients were operated on using Radio-Frequency energy assisted liver resection. Radio-Frequency energy was applied along the resection edge to create a 'zone of desiccation' prior to resection with a scalpel. RESULTS: Median resection time was 47.5 minutes (range 30-110). The median blood loss during resection was 30 mls (range 15-992) and mean pre-operative and post-operative haemaglobin values were 13.5 g/dL (SD+1.7) and 11.6 g/dL (SD+1.4) respectively. No blood transfusion was registered, nor was any mortality observed. There was one post-operative complication: a sub-phrenic abscess. Median post-operative stay was 8 days (range 5-86). CONCLUSION: Liver resection assisted by RF 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 Intensive Care Unit.
