ABSTRACT

Objective To investigate the efficacy of balloon dilatation in the treatment of traumatic biliary stricture(TBS).Methods Eighty-one patients with TBS who had been admitted into General Hospital of Chengdu Command from February 1997 to February 2007 were divided into 2 groups.In the control group,40 patients underwent choledoco-jeiunostomy with T tube stenting in the anastomotic stoma for 6 months.In the balloon dilatation group,41 patients received implantation of the balloon catheters along with the two arms of the T tube in the anastomotic stoma.The efficacy of different surgical procedures were analyzed by chi-square test.Results Seven patients in the control group were failed with a failure rate of 18%.Of the 7 palients,6 were transferred to receive balloon dilatation and 5 were cured.In the balloon dilatation group,only 1 patient was failed and the failure rate was 2%.The diameter of the anastomotic stoma ilq the balloon dilatation group was dilated gradually to 12 mm in 3 months.The difference upon the success rate of the operation between the 2 groups had statistical significance (x2=5.10,P＜0.05).Conclusions Balloon dilatation is effective in the treatment of TBS.
