Brief Summary

The treatment of anal fissure is mainly surgical. There are complications to this treatment, including damage to the inner anal sphincter and the appearance of fecal incontinence. Anal dilators are devices that allow gradual enlargement of the anus. To date, the use of these dilators has been in cases of sphincter scarring after a surgical procedure that has caused emptying difficulties. Only recently has the use of anal dilators been tried as a treatment for acute anal fissure. The study is designated to examine whether healing of the fissure can be achieved by conservative treatment with anal extensions and obviating the need for surgical treatment.

Study Arms (3)

research

EXPERIMENTAL

The subjects in the study group will undergo a series of 4 treatments by 2 certified physiotherapists for pelvic floor treatment that will include instruction in self-use of anal dilators once a week for four weeks. The anal dilation will be performed using Dilatan® anal dilators (Enterprises Sapimed, Alessandria) in varying sizes of 22, 23 and 27 mm. In the first week, a 20 mm dilator will be inserted twice a day for at least 10 minutes. In the second week, a 23 mm extender will be inserted into the anus, twice a day for at least 10 minutes. In the last two weeks, a 27 mm extender will be inserted twice a day for at least 10 minutes. To facilitate the insertion of the extender, patients will use lubricating cream. At the end of each week, patients will meet with a pelvic floor physiotherapist to make sure that the insertion is done properly, that there are no side effects and that it is possible to move on to the next step.

Device: Anal dilators

NO INTERVENTION

The subjects in the waiting group will be able after a month to choose to undergo surgery or also receive treatment by extenders.
