Abstract
The colon is a common site of gastrointestinal disease in patients with AIDS, and the frequency and severity of disease increases as immunosuppression worsens. In these individuals, the most common manifestations of colonic disease include diarrhea, lower gastrointestinal bleeding, and abdominal pain. Gastroenterologists caring for HIV-infected patients with colonic disease must be aware of the causes of these diseases and the proper endoscopic techniques needed to make an accurate diagnosis. This article reviews the indications for lower endoscopy and the differential diagnosis of colonic disease in patients with AIDS. The authors also review the techniques of colonoscopy, sigmoidoscopy, ileal intubation, and biopsy. In addition, the authors discuss the endoscopic appearances of various colonic diseases in patients with AIDS to assist the endoscopist in correctly identifying these disorders. This is a US government work. There are no restrictions on its use.
