AIM:To study the operative injury,post-operativecomplications,the hospitalization time,the post-operative survival rate of ultrasonic aspirationhepatectomy with a domestic new type of ultrasonicsurgical device in comparison with that of conventionaltechniques of hepatectomy.METHODS:A total 136 patients with hepatocellularcarcinoma(HCC,including 12 patients in 1991 and 124consecutive patients from July 1995 to December 2 000)underwent ultrasonic aspiration in liver resection(groupT)and 179 HCC patients received conventionalhepatectomy during the corresponding period(group C).The results of the two groups were compared statistically.RESULTS:There was no significant difference in the meanoperation time between group T(152±11 min)and C(144±11 min).No operation or hospital death occurredin both groups.In group T,the mean volumes of bleeding(463±15 ml)and blood transfusion(381±12 ml)weremarkedly less than those in group C(557±20 ml,and507±18 ml,respectively,P<0.05).The meanhospitalization time of group T(8.9±0.6 d)was markedlyshorter than that of group C(11.7d±0.6 d)(P<0.05).The incidence of complications in group T was markedlylower than in group C,post-operative jaundice occurredin 4/136 and 31/179,respectively(P<0.05),liver failurein 0/136 and 2/179,cholorrhea in 0/136 and 6/179,hydrothorax in 21/136 and 39/179(P<0.05),ascices in9/136 and 54/179,respectively(P<0.05).There wasno significant difference in the 1-year survival ratebetween the two groups(P>0.05),while the 3-yearsurvival rate of group T(64.2 %)increased markedlyas compared with that of group C(55.7 %)(P<0.01).CONCLUSION:The ultrasonic aspiration hepatectomywith a domestic new type of ultrasonic surgical devicecould evidently reduce the operative injury and post-operative complications,shorten the hospitalizationtime and prolong the survivals of HCC patients.
AIM: To study the operative injury, post-operativecomplications, the hospitalization time, the post-operative survival rate of ultrasonic aspirationhepatectomy with a domestic new type of ultrasonicsurgical device in comparison with that of conventionaltechniques of hepatectomy.METHODS: A total 136 patients with hepatocellularcarcinoma (HCC, including 12 patients in 1991 and 124 consecutive patients from July 1995 to December 2 000) underwent ultrasonic aspiration in liver resection (group T) and 179 HCC patients received conventional hepatectomy during the corresponding period (group C). The results of the two groups were There was no significant difference in the mean operation between group T (152 ± 11 min) and C (144 ± 11 min). No operation or hospital death occurred in both groups. In group T, the mean volumes of bleeding (463 ± 15 ml) and blood transfusion (381 ± 12 ml) were markedly less than those in group C (557 ± 20 ml, and 507 ± 18 ml, respectively, P <0.05). The mean hospital radiat The time of group T (8.9 ± 0.6 d) was markedly shorter than that of group C (11.7d ± 0.6 d) (P <0.05). The incidence of complications in group T was markedlylower than in group C, post-operative jaundice occurredin 4/136 and 31/179, respectively (P <0.05), liver failurein 0/136 and 2/179, cholorrhea in 0/136 and 6/179, hydrothorax in 21/136 and 39/179 (P <0.05) There was a significant difference in the 1-year survival rate between the two groups (P> 0.05), while the 3-year survival rate of group T (64.2%) increased ascices in9 / 136 and 54/179, respectively markedlyas compared with that of group C (55.7%) (P <0.01) .CONCLUSION: The ultrasonic aspiration hepatectomywith a domestic new type of ultrasonic surgical devicecould evidently reduce the operative injury and post-operative complications, shorten the hospitalizationtime and prolong the survivals of HCC patients.
