With The Surgery Methods That Integrate Subparagraph, Fenestration, Exclusion, Cut Expansion, Seton, Tube And Drainage Treats Complex Anal Fistula In The Effectivity Of Multi-center Clinical Research

Objective:To analyze the effectivity of curing complex anal fistula by sectioned fenestration indwelling combined with cutting, reaming and hanging line together with catheter drainage in Multiple clinical centers.Approach:Multi-center clinical use prospective study. According to the diagnose criteria and exclusion criteria of complex anal fistula, accepting 240 patients and grouping them into trial group and control group with completely random design. The 120 cases in trial group are used" Subparagraph,Fenestration, Exclusion, Cut expansion, Seton, Tube and Drainage". The other 120 cases in control group are used " cut, ream, hang the line approach. " Conduct the contrast research to two groups of subjectivities and the objectivity Validity target.Result:The 115 cases in trial group are cured,5 case was effectively healed and cured in the postoperative modification. In the follow-up study, no case recurred. The cure rate is 95.8%, obvious effective rate is 4.2%. the average time of operation is (39.01±8.23)minutes, the average time of treatment is(29.3±2.3)days, the area of the scar after curing is (4.75±0.68)cm2, the healing of incision is 116 cases of class A and 4 case of class B. The 105 cases in other group are cured,7 cases were obviously and effectively healed and 5 case was effectively healed. In the follow-up study,3 cases were recurred. The cure rate of control group is 87.5%, obvious effective rate is 5.8%, effective rate is 4.2%, recurrence rate is 2.5%. The average time of operation is (51.74±12.15) minutes, the average time of treatment is (36.3±3.8)days, the area of the scar after curing is (7.21±1.50)cm2, the healing of incision is 98 cases of class A, 19 case of class B and 3 case of class C. Obvious difference (P<0.05) existed in the two groups when complicated pain, bleeding and dysuria are concerned after operation.Conclusion:Compared with control group, our therapy owns the merits of high cure rate, shorter timing of curing, smaller scar, less pain, less complication, for the anal fistula surgery standardized method of operation and provide the scientific basis of merit as the standardization of anal fistula surgery operation promoting the use in clinical.
