Objective: To compare fistulectomy with primary closure of the wound and fistulectomy alone in the treatment of low anal fistula in terms of healing time.
Study Design: Randomized control trial.
Place and Duration of Study: Department of General Surgery Combined Military Hospital (CMH) Rawalpindi, from Nov 2006 to May 2007.
Material and Methods: Total 60 patients of low anal fistula were enrolled in this study after informed consent and ethical approval. Patients were divided in two groups (A and B) each containing 30 patients. Patient of group A underwent fistulectomy alone whereas patients of group B underwent fistulectomy with primary closure of wound. All the patients were followed two weekly for 06 weeks. On each visit, healing was assessed by naked eye examination of epithelialization and noted on a Proforma. SPSS 17 was used to analyze the results. A p-value of <0.005 was considered statistically significant.
Results: At 02 weeks after surgery, none of the patient in group A and 6.6% of group B patients showed wound healing, p-value was not significant i.e. 0.492. At 04 weeks after surgery, 23.3% of group A and 86.6% of group B patients showed wound healing p-value <0.001. At 06 weeks after surgery, 93.3% of group A and 100% of group B patients showed wound healing, p-value was not significant i.e. 0.492. Healing of wound was found more rapid in group B patients who underwent fistulectomy with primary closure of wound.
Conclusion: Fistulectomy with primary repair was a better treatment as compared to fistulectomy alone in terms of healing time of wound.
