Zusammenfassung:We investigated the effects of autologous vein transplant on bile duct injury repair, through observation of the hepatic and biliary system tissue morphology changes and animal survival after bile duct injury repair. Rabbits were equally divided into groups. Group A had cholecystectomy and common bile duct resection (length of 0.5 cm), transplant of an autologous vein (length of 0.5 cm), and stent implant. Group B had cholecystectomy and common bile duct resection (length of 1.0 cm), transplant of an autologous vein (length of 1.0 cm), and stent implant. The third group (group C) had cholecystectomy only. Two rabbits died in group A and group B; all experimental animals from group C survived. Regarding liver biochemical indexes at preoperative week 1, at postoperative month 1, and at postoperative month 3, we found no significant differences (paired t test, P > .05). Liver biochemical indexes between groups were also not significantly different (P > .05). At month 3, postoperative liver pathology of experimental animals showed no significant changes and no cholestasis; biliary epithelial cells were seen in the transplant vascular. We conclude that autologous vein graft can effectively repair bile duct injury for a short coloboma.
