Abstract
A retrospective review was performed of the clinical features present in 17 patients who were human immunodeficiency virus (HIV) positive requiring a diagnostic or therapeutic procedure for suspected appendicitis. Patients who were acquired immune deficiency syndrome (AIDS) free (n = 11) and those with AIDS (n = 6) were compared. Ten of the 11 patients who were AIDS-free had appendicitis. The morbidity rate was 9 per cent, similar to that expected in seronegative patients, but the appendix perforation rate was 50 per cent. Only two of the six patients with AIDS had appendicitis. Three suffered from an HIV-related disease process. Computed tomography (CT) was performed in four of the six patients with AIDS, and was considered of diagnostic help in three. In patients with AIDS, the morbidity rate rose to 50 per cent. Surgical decision-making with regard to HIV-positive patients who were AIDS-free with suspected appendicitis should be similar to that for seronegative patients. For patients with AIDS, alternative diagnostic strategies, including pre- operative CT, or possibly laparoscopy, should be considered.
