In a prospective study 116 patients underwent liver resection. Three different resection techniques, blunt dissection (n = 61), ultrasonic aspirator (CUSA) (n = 27) and jet-cutter (n = 28) were compared. Speed of resection, blood loss, transfusion rate, liver hilus clamping time and tissue damage were evaluated on the basis of area of transected liver surface. Liver resection with the jet-cutter was significantly faster with a resection time of 0.33 min/cm2 in comparison to blunt dissection (0.57 min/cm2) and CUSA (0.50 min/cm2) (P < 0.01) and associated with lower blood loss of 17.7 ml/cm2 (P < 0.01) than the other techniques (blunt dissection 32.5 ml/cm2, CUSA 24.3 ml/cm2). Tissue damage with respect to transaminases SGOT and SGPT was comparable to the other techniques. The jet-cutter is a promising new instrument in liver surgery.
