Anal Stenosis

About Anal Stenosis

Stenosis is a medical term that means narrowing or stricture. It typically occurs following some type of surgery where scarring causes the narrowing, although other conditions such as cancer, radiation, and certain infections can cause similar problems.


Anal stenosis usually causes symptoms such as pain with bowel movements, bleeding, difficulty evacuating stool, constipation, and a feeling of anal discomfort. Diagnosis requires evaluation with a rectal exam by an experienced provider. He or she can determine whether a stenosis is present and what the underlying cause is. Occasionally, with stenosis causing severe discomfort, this may require the exam to be done under anesthesia.

Treatment for Anal stenosis:

The treatment for anal stenosis depends on the cause. Sometimes, dilation of the stenosis or stricture may improve the problem. This may be done in the operating room, the office, or by the patient at home using self-dilation techniques. Alteratively, some plastic surgery with rotational or advancement flaps may needed to expand the surface area of the anus and prevent ongoing problems.
