| Abstract: | Laparotomy with a preoperative diagnosis of acute appendicitis disclosed a normal appendix in 105 children (22.1 percent). In less than half of these, another condition was found or later identified, which explained the symptoms leading to operation. Ovarian lesions, acute ileocolitis, and serositis were the most frequently identified abnormalities. Twelve patients (11 percent) underwent definitive procedures in addition to appendectomy. Among patients in whom no abnormality was identified at laparotomy, peritoneal cultures yielded a broad range of organisms in 42 percent of those who had cultures. This may represent a mild form of acute primary peritonitis and may explain the symptoms which were confused with acute appendicitis. |
