Applied research of intrahepatic subsegmental blood occlusion in the anatomical liver resection

Objective:To investigate the application of intrahepatic subsegmental blood occlusion in the anatomical liver resection.Methods:The clinical data of 62 patients with live cancers,were retrospectively analyzed.The intrahepatic subsegmental blood occlusion method group(group A) included 29 contiguous patients of liver cancer received anatomical hepatectomy while the traditional method group(group B) included 33 patients of liver cancer who received anatomical hepatectomy during the same period;Blood loss during operation and postoperative liver function were compared between these two groups.Results:In group A,4 patients ascites,no mortality and intraabdominal hemorrhage,liver function failure were noted.In group B,5 patients ascites,1 patient experienced liver function failure and died.Blood loss during operation and serum alanine transaminase(ALT) in the postoperative 5th,9th,14th values in group A were significantly lower than those in group B,There is statistical significance between the difference of the two groups(P0.05).Conclusion:The method of optional intrahepatic subsegmental blood occlusion for anatomical hepatectomy of HCC is one of the effective hepatic blood occlusion methods reducing perioperative blood loss and quickly recovering liver functions.
