Anorectal injuries incident to enema administration. A recurring avoidable problem.

Injuries to the anorectum have been described as having resulted from therapeutic enema use. We report three cases occurring in patients with premorbid perianal pathology. All extended hospitalization although each was managed nonoperatively. These accidents can be prevented by pre-enema rectal examination and attention to perianal anatomy and patient complaints of discomfort during the procedure.
