Clinical Study Of Therapy For High Anal Fistula With Reformed Operation And Staging Dressing-change

Purpose:To rise the cure rate of high anal fistula and protect the anal function we designed this new therapy way of reformed operation and staging dressing change. This operation adopts opening internal incision , countering drainage from left and right subsenquence and putting top aside. After the operation, we dress the wound differently by three stages, the first stage of inflammation,we treat it with relieving inflammation edema; The second stage of dissolving rotten and producing muscles we treat it with getting rid of necrosis constitutions and facilitate the wound to heal in the last stage of healing. 22 cases were studied with this new therapy method,contrasting to the traditional thread- drawing method. The cure rate .relapse rate,healing time , postoperation reaction, sequelae and the prssure of the anal canal were abserved. It shows that there exists no significant difference on both cure and relapse rate(p > 0. 05) while significant differece on healingtime, anal canal contractility, anal canal resting pressure, anal canal systolic pressure, anal canal maximum systolic time, postoperation reactions (pain swell, miction handicape) and sequalae (anal fluid, ir-ritabled stools) between two groups (p < 0.05). It indicates that the new therapy method is better than the traditional method in protecting the anal function. So this reformed operation binding staging dressing change is a better inethal of treating high anal fistula, with protecting the anal function and lower replase rate and sequlae.
