Abstract

Objective 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. Patients and methods This prospective study on consecutive 40 patients was conducted from July 2010 to February 2013. Patients were divided into two groups; 20 patients underwent lateral internal sphincterotomy (LS) and 20 patients underwent SPF. All patients were evaluated with respect to operative time and postoperative complications. Results were documented and statistically analyzed. Results The mean time of LS operation was 5.9 ± 0.97 min and that of SPF was 9.2 ± 0.89 min. 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. Conclusion On the basis of this study, we conclude that SPF operation has several advantages over LS in treatment of chronic anal fissure.
