Abstract

We evaluated the feasibility and effectiveness of combining two different electronic devices, the ultrasonic dissector (UD) and the harmonic scalpel (HS), during hepatic resection. One hundred consecutive patients underwent liver resection using UD plus HS between January and December 2 004 (UD + HS group). The ultrasonic dissector was used to fracture liver parenchyma and the uncovered vessel was sealed using the HS. Surgical outcomes were compared with 100 consecutive patients who underwent liver resection using the clamp crushing method. Operative variables, postoperative liver function, hospital stay, and type and number of complications were compared. The two groups were equivalent in term of demographic and pathologic variables. The UD + HS group had a decreased blood loss (500 ml versus 700 ml, P = 0.005), number of patients transfused (22 versus 39, P = 0.009), tumor exposure at the transection surface (4 versus 12, P = 00.012), and hospital stay (7 versus 8.5 days, P = 0.020). Postoperative major complications, in particular, fluid collection and biliary fistula, were significantly less frequent in the UD + HS group (2 versus 9, P = 0.030). A longer operative time was recorded in the UD + HS group (385 versus 330 minutes, P = 0.001). The combined use of UD with HS allows liver resection to be safely performed, with the advantage of reducing blood losses and surgery-related complications. The only major disadvantage may be a longer transection time.
