BACKGROUND: Diverticulum of the vermiform appendix is rarely encountered. Previous reports in the literature indicate that appendiceal diverticulum without inflammations are asymptomatic. METHODS: During the past 10 years, 217 patients have been evaluated in our office for chronic lower abdominal pain. Six patients in this group were unusual in that no diagnosis could be made after a complete history, physical examination, and multiple imaging and laboratory studies. Each patient had a normal computed tomography scan of the abdomen, upper endoscopy, colonoscopy, barium enema, and small bowel enteroclysis. Each of the 6 patients underwent an exploratory laparoscopy and appendectomy. RESULTS: All 6 patients in this series had acquired diverticulum of the appendix with inspissated intraluminal secretions without histological evidence of inflammation. The age range was 37 to 57 years. Most patients were male, and most had a single diverticulum projecting into the mesoappendix. All 6 patients had complete resolution of their chronic abdominal pain after the laparoscopic appendectomy. CONCLUSIONS: An unusual cause of mild chronic abdominal pain can be the presence of appendiceal diverticulum with inspissated intraluminal secretions. The evaluation of these patients is usually normal. Exploratory laparoscopy with appendectomy should be the final evaluation for patients with mild chronic abdominal pain.
