Several recent reviews have suggested that aggressive surgical intervention can reduce morbidity and mortality associated with intra-abdominal crises in AIDS patients. We reviewed our experience with 57 AIDS patients with 63 emergent laparotomies performed at 4 hospitals affiliated with the University of California in San Francisco. Fifty-five patients (96%) were homosexual men. Thirty-nine (68%) had been treated for an opportunistic infection. Indications for exploration included right lower quadrant pain consistent with appendicitis in 24 patients (38%), visceral perforation or obstruction in 11 (17%), right upper quadrant pain in 9 (14%), diffuse peritonitis in 8 (13%), and uncontrollable hemorrhage in 8 (13%). Perioperative mortality was 12% (7/57). Fifteen patients (26%) suffered major complications including pneumonia, sepsis, multi-organ failure, and intra-abdominal abscess. Forty-five of 50 survivors (90%) were receiving some type of chronic antimicrobial or antineoplastic chemotherapy, compared to only 2 of the 7 patients who died (28.6%) (P < 0.001). Lack of ongoing prophylactic treatment for AIDS-related disease, active opportunistic infections, Walter Reed VI classification, and ongoing sepsis at the time of exploration were noted to be associated with increased morbidity and mortality.

At our institution, helical CT of the abdomen and pelvis with intravenous and rectal contrast (CTRC) has become the modality of choice for investigation of patients with right lower quadrant pain and clinical suspicion of acute appendicitis. CTRC has proven useful for the diagnosis of acute appendicitis (AA) and at the same time identifies alternative diagnoses mimicking AA. This pictorial assay illustrates the imaging findings of AA and its mimickers including primary epiploic appendagitis, right-sided diverticulitis, torsion of Meckel's diverticulum, gynecologic disorders, obstructive uropathy, right lower lobe pneumonia, and other conditions.

Appendiceal malignancies are rare clinic entities. The clinical presentation of appendiceal malignancies is often atypical. Acute abdominal pain and acute appendicitis, which requires early surgical intervention, are the most common clinical presentations of appendiceal malignancies. In this case report, an adenocarcinoma of the appendix in a 64-year-old male from a nursing home has been presented. He had right lower quadrant pain for the last 5 days. On physical examination, he had significant guarding. Intravenous contrast-enhanced abdominopelvic tomography revealed no pathological features. Laparotomy under general anesthesia was scheduled. During exploration, a perforated appendicitis was observed. Formal appendectomy was performed. The patient was lost due to pneumonia and septic shock 5 days after surgical intervention. In addition, the natural history of the disease and its basic diagnostic and therapeutic aspects are discussed. Preoperative or intraoperative diagnosis may not be available for some patients. Thus, routine histopathological examination is essential for adequate diagnosis and treatment.
