The present study aimed to compare the standard lateral internal sphincterotomy at 3 o'clock with posterolateral internal sphincterotomy at 5 o'clock in regards healing time, postoperative recurrence and complications, particularly fecal incontinence.
The present study aimed to compare the standard lateral internal sphincterotomy at 3 o'clock with posterolateral internal sphincterotomy at 5 o'clock in regards healing time, postoperative recurrence and complications, particularly fecal incontinence. We hypothesized that performing internal sphincterotomy in a point midway between the standard lateral position and the posterior midline position would confer better healing and relief of symptoms with less incidence of fecal incontinence while avoiding the development of keyhole deformity.
