Intervention group: The patients with inclusion criteria will be evaluated for manometry and Wexner score before surgery. To evaluate the anal function, a validated Wexner incontinence scale score system (total incontinence score 0: best and 20: worst) and anal manometric indices will be measured 1 day before the surgery and 3 months after the operation. The Wexner scale was described by Wexner and Jorge and consisted of items about frequency of gas and fecal incontinence. Anal manometric measures and Wexner scores will be compared pre- and postoperatively. For doing anorectal manometry, the patient will be positioned in left lateral decubitus with knees flexed. For anal manometry, a Sphinctrometer system (MSM Promedico GmbH) will be used. After calibration, a probe will be introduced into the rectal ampulla up to 6 cm from the anal verge. Anal resting Pressure (ARD), anal maximum squeezing pressure (AMD), and Mean pressure will be calculated..
