| Objictive:Evaluation of type A botulinum toxin injection and lateral internal anal sphincter lesions expanding sector cut a small incision drainage in the treatmentâ…¡,â…¢anal fissure in the safety and effectiveness, and explore the steps and key points of its operation, introducing a new treatment of anal fissure The surgery.Methord:The Traditional Chinese Medicine University, Second Affiliated Hospital of patients met the inclusion criteria were observed, the total number of cases observed for 60 patients, randomized, parallel-group clinical trial, according to treatment order randomly divided into 2 groups, experimental group of 30 patients Use of botulinum toxin type A in the side of injection and anal sphincter lesions expanding sector cut a small incision and drainage, control group of 30 patients with anal fissure debridement and partial resection of internal sphincter in the side of the amputation, the safety of the two groups and effective Of indicators before and after contrast. Result:_Experimental group and anal stenosis anal incontinence after surgery, displacement, deformation, low incidence of anorectal pressure and sensory function test results:There were no significant differences in preoperative, p> 0.05, a significant postoperative Significant difference, P<0.01; postoperative incidence of acute urinary retention was no significant difference (P> 0.05); in the overall effect, operating time, healing time, scar area, wound healing and wound recovery was significantly less In the control group, P <0.05.Conclusions:Experimental group and control group than the first, with a cure rate of this study engaged in surgical wound healing time is short, the small size of scars, less pain, quick operation, if the advantages of minimally invasive surgery. Form and function and in the protection of the anus than the control group, the surgical clinical effect is not only good but also has higher security, worthy of clinical application.
