Abstract: 【Absract】〓Objective〓To investigate clinical characteristics of liver tumor in children. Methods〓A retrospective study was conducted in 22 cases of children with liver tumor between Jan 2011 to Jun 2013. AFP and CT/CTA scan were detected before operation. Twenty two cases were diagnosed by pathological examination...Among them,17 patients underwent surgical operation,..7 cases of them using CUSA and (or) Ligasure energy platform. Results〓CT scan showed 7 tumors in left lobe, 12 tumors in right lobe,..and 3 tumor between right and feft lobe...Pathological exam showed 14 hepatoblastoma,3 focal nodular hyperplasia, 2 infantilism angioendothelioma, 1 fibrous hamartomas,1 embryonic undifferentiated sarcoma,1 simple cyst...Eight cases underwent liver resection with CUSA and Ligasure,..the average of blood loss was 121 mL...9 cases underwent liver resection and the average blood loss was 248 mL. There were statistically significant differences between two groups, P<0.05. The hepatic porta were blocked in 7 cases and the average blood loss was 170 mL. Non-blocking was in 10 cases,..the average blood loss was 198.64 mL and there was no significant difference between the two groups...Seven cases with benign tumors were disease-free survival after operation. One case with embryonic undifferentiated sarcoma died six months after operation. In the 14 cases with hepatoblastoma, 9 cases underwent liver resection and these patients survived to now. And in 5 cases only received puncture biopsy of liver,4 cases died and 1 case survived. Conclusion〓Using precise liver resection to treat pediatric liver lesions, both benign and malignant,it is safe and effective. But in the hilum invaded or more than 3 lobes of the liver tumor,further improving therapeutic measures are necessary.
