[摘要] 目的 治疗高位肛瘘时为避免使用传统挂线产生较严重的后遗症，提出有效解决办法。方法 使挂线按照手术者设定的方向缓慢切割、引流，即通过改变肛管与瘘管两侧橡皮筋的压力面积来产生压强差，导致不同的切割速度和距离以达到定向切割目的；并将效果与传统挂线做比较。结果 使用定向挂线治疗的患者未出现肛管畸形、肛门漏气漏液及大便失禁等后遗症；通过肛管测压检验其影响，显示诸项指标无显著改变；对比效果优于传统挂线，差异有显著性(P<0.05)。结论 定向挂线能有效地避免传统挂线导致的后遗症，并能较好地完成对挂线的要求。

    [Abstract] Objective To find an efficient solution in case to avoid serious sequelae caused by traditional ligation when high anal fistula was treated.Methods Let the thread to incisione muscle slowly along the direction which operator designed.In order to obtain the purpose of directional incision,the different incisional velocity and distance should be gained by means of changing elastic stress arca to cause pressure difference between the sides of anal canal and fistula.Finally its effect was compared with traditional ligation’s.Results No sequelae such as anal canal deformity,anus air and juice leakage were appeared by using orientation seton.The anal canal measure pressure showed that all indexes affected by it weren’t distinctly changed.The contrastive outcome showed that it was better than traditional ligation.There was a significant difference between the two groups (P<0.05).Conclusion Using orientation seton could efficiently avoid the sequelae caused by traditional ligation,and perfectly achieve the demand for ligation. ......
