Use of dissecting sealer may affect the early outcome in patients submitted to hepatic resection.
BACKGROUND
Many technological devices have been used to avoid intraoperative bleeding during hepatic parenchymal transection and to avoid morbidity and mortality, but until now none is complete. The aim of this work is to prospectively analyze hepatic resection patients treated with a water-cooled high frequency monopolar device in order to evaluate its effectiveness.


METHODS
All consecutive patients who underwent liver resection by use of this device, between January 2003 until December 2007, were analyzed prospectively. The following variables were considered: age, sex, kind of disease, kind of liver resection, number of major/minor resections, total operative time and transection time, number and time of clamping, blood loss, time of hospitalization, morbidity, and mortality.


RESULTS
Between January 2003 and December 2007, 26 patients were analyzed prospectively (69% women, 31% men). Ages ranged from 18 to 84 years. Sixty-five percent of patients had a malignant disease; 35%, a benign disease. The procedures performed were two major hepatectomies (7.6%) and 24 minor hepatectomies (92.4%). Hepatic transection was performed in 35 to 150 min. Total operative time range was 120-480 min. The average blood loss was 325 ml (range 50-600 ml). The mean postoperative stays were nine days for all the patient and six days for non-cirrhotic patients.


CONCLUSIONS
The water-cooled high frequency monopolar device is useful for reducing ischemia-reperfusion damage due to the Pringle maneuver and for reducing the risk of morbidity. However, the Kelly forceps remains the only inexpensive instrument really essential for liver surgery.
