![]() The cardinal symptom of anal fissure is pain in the anus during and after defecation. The majority of fissures occur in the posterior midline of the anal canal multiple or lateral fissures may have other causes, such as Crohn's disease, ulcerative colitis, tuberculosis, and infection with HIV or syphilis. Some of the anterior fissures occurring in women result from childbirth. Physiologic studies using ambulatory manometry have confirmed the presence of sustained resting hypertonia in fissure patients. A history of constipation is not universally obtained however, some patients reported an episode of diarrhea before the onset of symptoms. Trauma to the anal canal secondary to the passage of a hard stool is believed to be a common initiating factor. The cause of anal fissure has been long debated. It is the most common cause of rectal bleeding in infants.

Keywords: Chronic anal fissure, internal sphincterotomy, sentinel pile flap On the basis of this study, we conclude that SPF operation has several advantages over LS in treatment of chronic anal fissure. Flatus incontinence was reported in 8/20 (40%) patients of the LS group and 2/20 (10%) patients of the SPF group wounds healed within 2 weeks in 12/20 (60%) patients of the LS group and 18/20 (90%) patients of the SPF group and recurrence occurred in 2/20 (10%) patients of the LS group and did not occur in the SPF group. The mean time of LS operation was 5.9 ± 0.97 min and that of SPF was 9.2 ± 0.89 min. ![]() Results were documented and statistically analyzed. All patients were evaluated with respect to operative time and postoperative complications. Patients were divided into two groups 20 patients underwent lateral internal sphincterotomy (LS) and 20 patients underwent SPF. This prospective study on consecutive 40 patients was conducted from July 2010 to February 2013. ![]() The aim of the study was to compare the results of internal sphincterotomy and sentinel pile flap (SPF) in the treatment of chronic anal fissure. ![]()
