胆管空肠Roux-en-Y吻合与内镜下乳头肌切开术后肠胆返流与胆汁排泄的对比研究

FUNCTION OF ANTI REGURGITATION AND ABILITY OF DRAINING BILE AFTER TWO DIFFERENT INTERNAL CHOLECLLCH OENTENAL DRAINAGE.

目的 研究两种胆肠内引流术术后抗返流及通畅排泄胆汁的功能 ,并进行比较。方法 利用 B超及钡餐透视检查术后返流情况。利用核素显像检查术后胆汁排泄通畅程度。结果 Y组术后返流率 (2 8% ) EST组术后返流率 (10 0 % ) ,Y组优于 EST组 (P<0 .0 1)。Y组术后肝脏半排时间 :14 .5± 0 .69秒 ;EST组 :13 .78± 0 .4 6秒 ;空白对照组 ,14 .5 8± 0 .61秒 (P>0 .0 5 )。结论 EST较 Y式吻合术后抗返流功能差 ,返流率高。 EST与 Y式吻合后胆汁排泄通畅程度相似 。

Objective To study the ability of draining bile and the function of anti regurgitation of two operative models of internal chloedochoenteral drainage.Methods BUs and Barium meal flreoscopy were used to observe choledochoenteral reguritation after internal drainage,and nuclide imaging to observe the ability of draining bile after internal drainage. Results the regurgitant rate of Y group was 28%,the regurgitant rate of EST group was 100%.X 2 test showed extremely significant.The postoperative two median hepatoexcretory time was 14.58±0.613 in normal control group,14.8±0.69 in Y group and 13.78±0.465 in EST group,There were no significant differences between them.Conclusion The function of anti regurgitation of Y group is better than that of EST group,and the latter has a highly rate of choledochoenteral regurgitaion.The ability of draining bile of the two groups are same,and they all reach the normal demand.
