Effects of two methods for hepatic vascular occlusion in resection of giant hepatic hemangioma

Objective To evaluate the clinical effects of two methods for hepatic vascular occlusion in resection of giant hepatic hemangioma. Methods A total of 20 patients with giant hepatic hemangioma who were hospitalized in Tianmen Hospital of Traditional Chinese Medicine from January 2008 to December 2014 were divided into group A and group B,with 10 patients in each group. Pringle maneuver was applied for group A,and Pringle maneuver combined with inferior vena cava( IVC) clamping was applied for group B. The time of operation,time of portal triad clamping,intraoperative blood loss,blood transfusion rate,and indices for postoperative liver function were compared between the two groups. The t- test was applied for comparison of continuous data,and Fisher's exact test was applied for comparison of categorical data. Results The two groups showed no significant differences in time of operation and time of portal triad clamping( P > 0. 05),and compared with those in group A,the patients in group B had significantly less intraoperative blood loss and significantly lower volume and rate of blood transfusion( P < 0. 05). Compared with those in group A,the patients in group B had significantly lower levels of aspartate transaminase,alanine transaminase,and total bilirubin on the third and seventh days after surgery( all P < 0. 05). However,the incidence of postoperative complications showed no significant differences between the two groups( P > 0. 05). Conclusion The method of IVC clamping combined with Pringle maneuver can reduce intraoperative blood loss and is beneficial to the recovery of postoperative liver function,and thus it is worthy of clinical promotion and application.
