Background:An anal fistula is a tubular tract that joins the mucosa of the anal canal to the perianal skin by means of two epithelial surfaces. The present study was conducted to assess anal incontinence among patients with fistula in ano. Materials & Methods:66 patients presented with fistula their incontinence was evaluated using both Kamm's and Wexner's grading systems. They also got an evaluation using anal manometry. Three months later, the patients who underwent draining seton surgery had the same evaluation to determine their level of continence. Results: Out of 66 patients, males were 40 and females were 26. The duration of disease was less than 1 year in 36, 1-5 years in 23 and >5 years in 7 patients. Comorbidity seen were diabetes in 5, hypertension in 4 and CAD in 1 patient. The previous surgery performed was lay open fistula in 15, incision and drainage in 43 and Seton operation in 8 patients. Type of fistulawas intersphincteric in 7, high transphincteric in 20, low transphincteric in 11, suprasphincteric in 3 and low fistula in 24 patients. The difference was significant (P< 0.05).Kamm score 0 was seen in 35, 1-2 in 20, 3-4 in 3 and >5 in 8 patients. The difference was significant (P< 0.05).Wexner’s score0 was seen in 41, 1-2 in 16, 3-4 in 5 and >5 in 4 patients. The difference was significant (P< 0.05). Conclusion: Neither the resting anal tone nor the squeeze anal tone significantly changed after draining seton surgery.
