RÉSUMÉ
Objective To investigate the effect of implantation of bone marrow mononuclear cells (BM-MNCs)on neovascularization and ischemic-type intrahepatic biliary lesion in rabbits.Methods The animals were divided into the sham-operation group, experimental model group and BM-MNCs implantation group with 10 rabbits in each. The animal model of ischemic-type intrahepatic biliary lesion was established by clamping the hepatic artery and common bile duct. The BM-MNCswere isolated from the tibial plateau by means of density gradient centrifugation and were implanted through the common hepatic artery. Changes of some biochemical markers such as ALT, AST, ALP,γ-GT, TBIL and DBIL etc. were detected. In 4 weeks after operation, the cholangiography, histopathological manifestation, differentiation of BM-MNCs, and microvessel density were observed.Results At each observation time, the degree of change of biochemical markers in group C was lower than that in group B. The engrafted cells could differentiate into vascular endothelial cells. The intrahepatic biliary lesion of group B was severer than that of group C but had fewer new capillary blood vessels around it. Conclusion The implantation of BM-MNCs can promote neovascularization and increase blood supply to the ischemic bile duct to diminish or prevent ischemic-type intrahepatic biliary lesion.
RÉSUMÉ
Situs inversus is a rare condition of anatomical alteration, and the patient with gallbladder disease treated by laparospic cholecystectomy is rather scarce. In this condition, the operation needs to be adjusted. In this article, we reviewed the relevant literatures about the operation in the patients with this uncommon malformation and analyzed the modification of the operation.
