Aetiology
Foreign bodies in the anus or rectum are often caused by inappropriate insertion of objects into the body, either intentionally or accidentally. This can include everything from children inserting small objects into the anus or rectum, or adults engaging in activities such as anal sex.
Diagnosis
Diagnosis can be made by physical examination and/or imaging. X-rays may be used to identify the size, shape, and location of the foreign body.
Differential diagnosis
Differential diagnosis includes anal fissure, anal fistula, rectal prolapse, colorectal cancer, and fecal impaction.
Treatment
Treatment depends on the size, shape, and location of the foreign body. Small objects may be able to be removed manually with forceps or a flexible sigmoidoscope. Larger objects may require endoscopic or surgical removal.
Prognosis
If the foreign body is successfully removed, the prognosis is usually good. If the foreign body is not removed, complications can occur. These can include infection, bleeding, and perforation of the rectum or anus.
