报告252例,一期愈合率93.6％。方法是术前1日给消炎剂、止血剂。骶骨麻醉或腰麻。以软质探针从外口探入,在内口伸出,以探针表明的瘘道为中间线,向两侧做围绕肛管的弧形切开。切口外宽内窄,以内口为顶角成扇形,外口的宽度以能暴露内口为度。如瘘道弯曲,探针不能一次贯穿内外口,可分次探入,分次切开;如瘘道复杂,可做复层弧形切口。搔刮管壁,清除腐败物,对结缔组织原则上不剔除,只做平整性修剪。出血点不做创缘内的永久保留性结扎。对内口处只做搔刮,不做扩大修剪。切口自然对合,贯穿基底部一次缝合,注
Report 252 cases, a rate of 93.6% healing. The method is to give anti-inflammatory agent and hemostatic agent on the 1st day before operation. Sacrum anesthesia or spinal anesthesia. Soft probe probe from the outside mouth, sticking out in the mouth, the probe shows the fistula as the middle line, to do both sides of the arc around the anal canal incision. The incision width is narrower and narrower, with the inner mouth as the top corner into a fan shape. The width of the outer mouth can expose the inner mouth for the degree. If the fistula is curved, the probe can not penetrate the inner and outer openings all at once, and it can be explored in different times and in different stages; if the fistula is complex, the curved arc incision can be made. Scratch the wall, remove corrosive, in principle, not remove the connective tissue, only smooth pruning. Bleeding points do not create permanent retention within the margin of the ligation. Scratch only inside the mouth, not to expand the pruning. Natural incision incision, through the base of a suture, note
