The Study Of The Self-Extend Of Internal Anal Sphincter Technique For The Treatment Of Chronic Anal Fissure

BACKGROUND: Anal-fissure is a disease with the skin split and infect ulcer from the lining of the anal to the edge of the anal. It can be divided into acute and chronic. Piquet hemorrhoids, anal hypertrophy papilla and anal-fistula are the concomitants of the chronic anal-fissure. Anal-fissure is a familiar disease.Eisenhammer(1959) advanced that we should adopt the internal sphincterotomy technique.Now, the essence of anal-fissure is the ulcer with the lack of blood. The key of the cure is relaxing the spasm, reducing the anal rest pressure, ameliprating the blood circle. In recent years, there are many developments with pathogeny, pathology treatment and conception.The operation is also the dominant status in the treatment of the anal-fissure. But there are many complications as the anal dysfunction and anal "keyhole" which affect the life. For the sake of obtaining a new operation with having one-off cure and maximumly protecting the function of anus, we designed self-extend of internal anal sphincter technique with the minimal invasiveness and localized treads in surgery.PURPOSE: We hope self-extend of internal anal sphincter technique can cure anal fissure, decrease treatment course and complications, improve the living quality markably.METHOD:24 cases with chronic anal fissure tha suit require were divided into two groups. Both the groups had 12 cases.The thereapy group adpopter self-extend of internal technique, while the control group adopted internal sphincterotomy technique. We compared the thereapy group with the control group in the curative effect, treatment course, postoperative complications, while compared the thereapy group with the normal group in anal rest pressure and most anal contract pressure.RESULT:There was no obviously difference between the thereapy group and the control group in curative effect、relapseand some complications as pain、urinating、haemorrhage et al (P＞0.05), but in treatment course、the anal dysfunction and anal "keyhole" showed markable difference( P＜0.05 ). There was obviously difference between the thereapy group and the normal group in anal rest pressure before-therapy (P＞0.05). There was no obviously difference between the thereapy group and the normal group in anal rest pressure after-therapy and most anal contract pressure (P＞0.05).CONCLUSION: The self-extend of internal anal sphincter techniques are equally effective in curing the anal fissure.The anal function is protected better than the internal sphincterotomy technique. So we believe that the self-extend of internal techniques is feasible.
