Proctitis and Sexually Transmissible Diseases of the Colon.
In patients with gastrointestinal symptoms and a history of anal-receptive intercourse, a careful but explicit history concerning sexual preferences and practices is required. Clinically, four infectious syndromes can be distinguished: perianal disease, proctitis, proctocolitis, and enteritis. Each of these syndromes may be caused by a certain range of pathogens. In immunocompromised patients, additional diseases must be considered. Clinical examination, a rectal swab with incubation in specific transport media, as well as a Gram stain of mucus or pus from a rectal swab, in combination with a rectosigmoidoscopy are helpful in differentiating specific diseases. Stool cultures and serologic examinations may identify specific causes of colitis or enteritis, but are of minor importance in the case of anorectal disease. Good treatments are available for most sexually transmitted anorectal diseases. An additional role for the treating physician and other healthcare providers is to educate and counsel patients and their sex partners on ways to adopt safer sexual behavior.
