Abstract:
ObjectiveTo compare the safety of cavitron ultrasonic surgical aspirator (CUSA) combined with high-frequency electrotome versus harmonic scalpel in hepatectomy.MethodsClinical data of 102 patients undergoing hepatectomy using CUSA combined with high-frequency electrotome or harmonic scalpel in Sun Yat-sen Memorial Hospital of Sun Yat-sen University between January 2011 and January 2014 were retrospectively studied. The patients were divided into the hepatectomy using CUSA combined with high-frequency electrotome group (the CUSA group,n=53) and the hepatectomy using harmonic scalpel group (the harmonic scalpel group,n=49). In the CUSA group, 32 were males and 21 were females with the average age of (48±11) years old. In the harmonic scalpel group, 31 were males and 18 were females withthe average age of (49±13) years old. The informed consents of all patients were obtained and the local ethical committee approval had been received. Porta hepatis was occluded by selective porta hepatis exclusion during hepatectomy. The interval of selective portal hepatis exclusion, intraoperative blood loss and postoperative complications of the two groups were observed. The observation indexes of the two groups were compared usingttest or Chi-square test.ResultsThe interval of selective portal hepatis exclusion of the CUSA group was (13±2) min, which was signiifcantly shorter than (23±3) min of the harmonic scalpel group (t=-19.946, P<0.05). The intraoperative blood loss of the CUSA group was (293±53) ml, which was signiifcantly less than (468±54) ml of harmonic scalpel group (t=-16.510,P<0.05). The incidence of biliary leakage of the CUSA group was 4% (2/53), which was signiifcantly lower than 16% (8/49) of the harmonic scalpel group (χ2=4.537, P<0.05).ConclusionsCompared with harmonic scalpel, CUSA combined high-frequency electrotome in hepatectomy has the advantages of less intraoperative blood loss, shorter interval of selective portal hepatis exclusion and lower incidence of biliary leakage. Thus, the safety of hepatectomy is enhanced signiifcantly.
