title: The use of barium enema in the evaluation of patients with possible appendicitis.
abstract: Patients with right lower quadrant pain and possible appendicitis may present a difficult diagnostic dilemma to the surgeon. Barium enema has been used as an adjunctive test in the evaluation of patients with right lower quadrant pain in whom the diagnosis is unclear. The authors retrospectively reviewed their experience with 33 patients to determine the value of barium enema. The average age was 32 years (range, 2-89 years). Twenty-five patients had nonfilling of the appendix; nine of these patients had a mass effect on the cecum. Three patients had partial filling of the appendix and five patients had a normally filled appendix. Of the 16 patients who had nonfilling of the appendix without a filling defect of the cecum, 14 patients underwent operation. Eleven patients had appendicitis and three patients had a normal appendix. Two patients with nonfilling did not undergo operation and did well. All patients with a filling defect of the cecum on barium enema had appendicitis. All patients with partial filling of the appendix had appendicitis. Of five patients with normal appendices on barium enema, one patient had a diverticular abscess and underwent operation, and another patient had Meckel's diverticulitis which was excised. Barium enema can provide information to aid in the management of patients in whom the diagnosis of appendicitis is not clear. It can prevent unnecessary operation in some, and assist in earlier operation in others.
