球囊扩张法治疗损伤性胆管狭窄的前瞻性研究

目的 探讨球囊扩张法治疗损伤性胆管狭窄(TBS)修复术后再狭窄的效果.方法 将1997年2月至2007年2月成都军区总医院收治的81例TBS患者按随机数字表法分成2组:对照组40例,采用传统胆肠吻合术,术后T管支撑6个月;球囊组41例,方法同对照组,同时在吻合口置人球囊,并逐渐扩张肝门部胆管空肠吻合口及上方胆管.两组疗效比较采用x2检验.结果 对照组7例失败(18%),其中6例改用球囊扩张治疗后5例获得成功.球囊组2个月内吻合口径达到12 mill,再维持1个月后将T管和球囊拔出,仅1例失败(2%).两组比较差异有统计学意义(x2=5.10,P＜0.05).结论 球囊扩张法能大大提高TBS修复术的疗效.

Prospective study on the treatment of traumatic biliary stricture by balloon dilatation

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.
