ABSTRACT

Objective To evaluate the efficacy of mini-clamp crushing combined with saline-linked diathermy in hepatectomy for giant hepatocellular carcinoma(HCC).Methods The clinical data of 58 patients with giant HCC(diameter≥10 cm)who received hepatectomy with the mini-clamp crushing technique(miniclamp crushing group)at the Southwest Hospital from April 2006 to December 2009 were retrospectively analysed.According to the tumor size,location and Child classification,the clinical data of 58 patients with similar parameters and received hepatectomy with traditional clamp crushing technique(control group)were selected from the database to conduct the matched case-control study.All the peri-and postoperative data were compared and analysed via one-way ANOVA,chi-square test and Fisher's exact test.Results The median blood loss and transfusion of control group were 850 ml and 650 ml,which were significantly higher than 400 ml and 550 ml of mini-clamp crushing group(F=16.23,5.63,P＜0.05).Twenty-four patients in control group needed blood transfusion,which was significantly larger than 6 of mini-clamp crushing group(χ~2=14.57,P＜0.05).The median time for parenchymal transection and portal triad clamping of control group were 45 minutes and 16 minutes,which were significantly shorter than 86 minutes and 35 minutes of mini-clamp crushing group(F=12.76,11.23,P＜0.05).The numbers of patients in control group who had complications and blood loss were 43 and 28,which were significantly larger than 13 and 8 of mini-clamp crushing group(χ~2=18.69,16.11,P＜0.05).The numbers of patients who had bile leakage,encapsulated effusion of the liver cut face and hepatic insufficiency were 8,5 and 2 in control group,and were 2,3,0 in mini-clamp crushing group,with no significant difference(χ~2=3.04,0.54,2.04,P＞0.05).Conclusion Mini-clamp crushing combined with saline-linked diathermy for the treatment of g4ant HCC is mone effective and available than traditional clamp crushing in terms of reducing blood loss and complications.
