This study is aimed at studying the effectiveness and safety of surgical treatment of chronic anal fissure.


A chronic anal fissure is a rupture of the mucous membrane of the anal canal, lasting more than 2 months and resistant to non-surgical treatment. This condition is accompanied by a strong pain syndrome during and after defecation (defecation). This condition is most often found in young and able-bodied adults, so the issue of treatment is of particular relevance.

The main cause of the development of a chronic anal fissure is a spasm of the internal sphincter. It should be eliminated first of all to ensure effective therapy.The investigators plan to treat a chronic anal fissure by performing a lateral subcutaneous sphincterotomy, without excision of the fissure.
