BACKGROUND Promotion of healing of the anal wound after fistulotomy may help accelerate recovery and return to work. The present study aimed to assess the effect of marsupialisation of the edges of the laid open fistula track on wound healing after anal fistulotomy for simple anal fistula. METHODS This was a prospective randomised trial on patients with simple anal fistula. Patients were randomly assigned to one of two groups; group I underwent anal fistulotomy and group II underwent anal fistulotomy and marsupialisation of the edges of the laid open track. Outcomes of the study were time to achieve complete wound healing, operation time, postoperative pain and complications. RESULTS Sixty patients of mean age of 40.8 years with simple anal fistula were randomly divided into two equal groups. No significant differences between the two groups regarding operation time (16.8 vs 18.4 minutes; P = 0.054), postoperative pain score (1.6 vs 1.2; P = 0.22), and complication rates were recorded. Group II achieved complete healing in a significantly shorter duration than group I (5.1 vs 6.7 weeks; P < 0.0001). CONCLUSION Marsupialisation of the edges of the laid open fistula track after fistulotomy resulted in quicker wound healing with similar complication and recurrence rates to lay open fistulotomy alone.
