    Treatment of patient with high anal fistulas has become complicated and post-operative complications are common. The aim of this study was to evaluate post-operative complications of primary sphincter’s repair technique in patients with high anal fistula. An interventional quasi-experimental study was conducted on 60 patients(42 male & 14 female) with high anal fistula. The most frequent age group was 4th decade in men and 3rd decade in women. Samples were collected in census manner. The method consisted of approach through intersphincteric space, cutting fistula tract. Later, there is an excision of internal opening by punch biopsy and internal sphincter repair. Finally, fistula tract is excised in external sphincter and repaired then. All patients were followed up for at least one month and their complications were evaluated by clinical examination. Relative gas incontinence in 4 patients(6.6%) was the most frequent complication. Recurrence in 2 patients (3.3%) and soiling in 2 patients(3.3%) were the followings. There was no case with complete incontinence. All cases with soiling and recurrence had trans-sphincteric fistula. In contrast to other studies, the frequency of post-operative complications was less. Probable differences would have occurred if the present research had used standard questionnaires or had followed up their patients longer than 1 month.
