title: Perianal manifestations of human immunodeficiency virus infection: experience with 260 patients.
abstract: OBJECTIVE
  Individuals infected with the human immunodeficiency virus often have disorders affecting the anorectum. These disorders may be complex and difficult to treat. We reported our early experience with 40 human immunodeficiency virus-positive patients with perianal disorders in 1990. We now present our series of 260 consecutive human immunodeficiency virus-positive patients with perianal disorders who underwent evaluation between 1989 and 1996 to examine the distribution of disorders, their treatments, and outcomes.
  
  
  METHODS
  Patients were identified at initial presentation and followed prospectively.
  
  
  RESULTS
  Two-hundred forty-nine (96 percent) of 260 patients were male, with an average age of 34.9 (range, 19-58) years. Average duration of human immunodeficiency virus positivity was 5 years, 5 months, with a maximum of 11 years, 5 months. Median CD4 count was 175 (range, 2-1,100) cells/mm3. Only 89 (34 percent) patients satisfied the criteria of the Centers for Disease Control and Prevention's for acquired immunodeficiency syndrome at presentation. The most frequent major presenting symptoms were anorectal pain (55 percent), a mass (19 percent), and blood in the stool (16 percent). Risk factors included homosexuality (75 percent) and a prior history of sexually transmitted disease (45 percent). Forty different perianal disorders were identified, which were categorized as benign noninfectious (18), infectious (14), neoplastic (6), and septic (2). The most common disorders were condyloma (42 percent), fistula (34 percent), fissure (32 percent), and abscess (25 percent). Neoplasms were present in 19 patients (7 percent). One hundred seventy-one patients (66 percent) had more than one disorder, with an average of 2.9 disorders among these patients. Four hundred eighty-five procedures were performed on 178 patients (2.7/patient), with no mortalities and a 2 percent complication rate. Thirty-one patients (12 percent) died during the course of follow-up, but anorectal disease was the cause of death in only two patients.
  
  
  CONCLUSIONS
  Perianal manifestations of human immunodeficiency virus infection are common, often multiple, and varied. Patients with perianal disorders seek treatment throughout the course of the human immunodeficiency virus infection, and a perianal condition may be this disease's initial manifestation. Although recurrence is common and healing delayed, improved overall management of human immunodeficiency virus infection and a healthier human immunodeficiency virus-positive patient population have improved the outcome of surgical intervention in human immunodeficiency virus-infected patients with perianal disorders.
