Appendicitis in acquired immunodeficiency syndrome.

Reports in the surgical literature are few regarding common intra-abdominal disease processes, such as gallstone disease or appendicitis, in patients with AIDS and instead have focused on AIDS-related intra-abdominal diseases that infrequently require surgical intervention unless complicated by bleeding, obstruction, or perforation. A literature review for appendicitis in AIDS patients revealed only 30 well-documented cases drawn from 13 studies, with a 40% perforation rate and frequent delays and errors in diagnosis. A 7-year experience with 28 patients with appendicitis and AIDS from 4 urban San Francisco hospitals is reviewed. There were no perioperative deaths and an 18% postoperative complication rate. Five patients (18%) were found to have normal appendices with other intra-abdominal pathology, and an AIDS-related etiology for appendicitis was discovered in 7 of 23 patients with appendicitis (30%). With the exception of diffuse versus localized abdominal pain, no preoperative symptom or sign was useful in differentiating AIDS-related and non-AIDS-related disease. Aggressive use of ultrasound and abdominal computed tomographic scanning, along with early surgical intervention, is recommended.
