Reserved Sphincter Hung Surgery In The Treatment Of High Anal Fistula

The canal of high anal fistula lies through the anorectal ring or above the ring, which brings much difficulties for the therapy. How to decline the rate of recurrence and restore the anal function are always two prominent problems of therapy for high fistula. To seek for an ideal and effective new surgical method becomes an important task. So the study is specially selected to meet the need of high curative rate and well anal function restored. The patients are divided into therapy group and control group. The therapy group with sphincter saving and counter drainage, the control group with thread-drawing. Then compare with cu- rative rate, rate of recurrence, treatment course, complications, sequelae and anorectal pressure in two group The results show: no significent difference in cu- rative rate and the rate of recurrence (P>0. 05) ,but significent difference in anal canal constractive force, quiescent pressure, constractive pressure, maximal con- stractive force, complications (pain, distention, sinking , retention, etc. ) and sequelae (fluid leaking from anus). (P>0. 05) The study indicates that the therapy group is much superior to the control group in function protection with fewer complications and sequelae. It also indi- cates the new surgical method is an effective resolution with advantages of better protection of anal function, low rate of recurrence and fewer sequelae.
