Abdominal and anorectal surgery and the acquired immune deficiency syndrome in heterosexual intravenous drug users.

Over a period of seven years, 474 patients with acquired immune deficiency syndrome (AIDS) or AIDS-related complex were admitted on 782 occasions to the St. Francis Medical Center, Trenton, New Jersey. Abdominal surgery was performed on 16 (3.4 percent) patients, 14 (88 percent) of whom were heterosexual intravenous drug users. Anorectal surgery was performed on 20 (4.2 percent), 14 (70 percent) of whom were intravenous drug users. Intravenous drug users undergoing abdominal surgery had the same types of surgical abdominal conditions that occur in the general population. None required surgery for complications secondary to cytomegalovirus, visceral lymphoma, or visceral Kaposi's sarcoma. The postoperative morbidity rate was 72 percent. The postoperative mortality rate (30 day) was 0 percent. No intravenous drug users who underwent anorectal surgery had associated anorectal malignancies or infectious diseases. Five of six homosexual patients had either an anorectal malignancy or an associated anorectal infectious disease. Anorectal wounds did not heal within one month in one third of the intravenous drug users. The rate of wound healing was inversely related to the white blood cell count. One third of the intravenous drug users undergoing anorectal surgery were dead within six months.
