Abstract
Lateral internal sphincterotomy is used for the treatment of a chronic anal fissure. There is a lack of consensus for the amount of internal sphincter division necessary in the surgical treatment of an anal fissure. The anatomy of the anal sphincters and the subcutaneous partial sphincterotomy technique are presented with fresh anal canal specimen photographs. Lateral internal partial sphincterotomy is performed in 43 patients in the office between 2012 and 2013. The patients were questioned about their bowel habitus and any problem with anal control before the operation. Postoperatively, the patients were followed up by office visits and telephone calls at 1 week, 1 month, and 6 months. Data were collected prospectively. Forty of the patients (93 %) were pain free in 1 week after the operation. Further sphincter fibers were divided in three patients (7 %) because of the persistent pain. The most common complication was the sensation of burning (n = 9, 20.9 %) around the anus. Bleeding in three patients, itching around the anus in two patients, and incontinence to flatus in one patient were the other complications. None of the patients developed fecal incontinence in the follow-up period. Lateral internal partial sphincterotomy is a safe, effective, and reproducible technique for the management of chronic anal fissure pain.
