A mini T-tube is introduced for the bile duct anastomosis of rat liver transplantation as well as interval bile collection. The validity of the T-tube was evaluated in 14 liver-transplanted rats and compared to 14 rats using traditional stent for bile duct anastomosis. Changes of biliary tree after the T-tube anastomosis were examined by T-tube cholangiography on sample rats at 4 days and at 4 months after liver grafting. Additionally, bile volumes and rates of bile salt secretion were compared in the continuously flowing cannula and the chronic T-tube fistula in normal rats. The results show that the mini T-tube facilitates bile duct anastomosis and study of bile secretion after liver transplantation in rats without increase in surgical difficulty or interference of biliary enterohepatic circulation.
一种微型T管被用于大鼠肝移植的胆管吻合以及间歇性胆汁收集。在14只肝移植大鼠中评估了T管的有效性，并与14只使用传统支架进行胆管吻合的大鼠进行了比较。在肝移植后4天和4个月，通过对样本大鼠进行T管胆管造影检查T管吻合术后胆管树的变化。此外，还比较了正常大鼠连续流动插管和慢性T管瘘中的胆汁量和胆汁盐分泌率。结果表明，微型T管有助于大鼠肝移植后的胆管吻合和胆汁分泌研究，且不会增加手术难度或干扰胆汁肠肝循环。
