Sphincterotomy up to the dentate line provided a faster and definitive healing within the time limits of this study, but it was associated with a significant alteration in anal continence. In turn, sphincterotomy up to the fissure apex was free of significant disturbance of continence, but its healing effect was slower and it was prone to an insignificantly higher rate of treatment failure.

BackgroundThe aim of this study was to evaluate our experience in managing high anal fistulas with a simple modification of the cutting seton.MethodsWe performed a retrospective review of standardized patient charts and of prospectively collected scores and questionnaires. Surgical outcomes of 128 consecutive, well-documented patients with high anal fistulas, including anterior transsphincteric fistulas in females, treated using a hybrid seton, were analyzed.ResultsNo significant complications occurred. The mean postoperative pain scores on a visual analog scale were 3.23 and 0.61, on days 1 and 7, respectively. Complete healing was achieved in 67 cases (52.3 %) at 1 month and in all cases (100 %) at 3 months. Recurrent fistula was noted in 2 patients (1.5 %) at 6 and 12 months. The mean postoperative incontinence scores at 3 and 12 months did not differ significantly from the preoperative score (p = 0.061, Wilcoxon’s test). The depression, life style, and embarrassment item scores of the fecal incontinence quality of life index improved significantly after surgical treatment.ConclusionsThe results of this series suggest that the hybrid seton might be a valid alternative for the treatment of high anal fistulas, eliminating the need for postoperative adjustments. The slow and stable cutting of the sphincter seems to have a positive effect on the maintenance of continence. The successful outcome is associated with significant improvement in quality of life.

Local anesthesia reduces post-operative pain and facilitates patients' mobilization and discharge along with decreasing the early post-operative complications. Thus, LA is a safe and advantageous method to be applied in inguinal hernia repair.

Diamond-flap anoplasty performed in a standardized and calibrated manner is a highly successful method for the treatment of anal stenosis caused by previous hemorrhoidectomy.
