Value of diagnostic laparoscopy in young women with possible appendicitis.

Removal of a normal appendix because of suspected appendicitis occurs most frequently in women of reproductive age. We investigated the value of laparoscopy in the diagnostic evaluation for possible appendicitis in women of childbearing age. Fifty-one women were entered in a management protocol, which included diagnostic laparoscopy in instances with atypical features. Twenty patients underwent immediate appendectomy because of history and physical findings classical for appendicitis; 31 women with atypical history and physical findings underwent an initial diagnostic laparoscopy. In the group of patients who underwent immediate appendectomy because of classical presentation, five of the appendices removed were normal. At laparoscopy, appendicitis was diagnosed in five patients, another disease in 15 and no diagnostic abnormality was found in six. Five patients had a normal appendix removed, two because of questionable inflammation and three because of nonvisualization of the appendix. There were no false-negative examination results. Twenty-one patients required no further operative intervention after laparoscopy. The negative appendectomy rate remained unchanged (ten negative appendectomies of 30 performed). Definitive diagnoses of eight instances of pelvic inflammatory disease, six of ruptured ovarian cysts and one instance of ileitis of the small intestine were made earlier than would have been possible without diagnostic laparoscopy in this setting. Diagnostic laparoscopy permits earlier definitive diagnosis and prompt institution of appropriate therapy for disease of the female reproductive tract that simulates appendicitis. Caution is advised, however, when diagnostic laparoscopy is applied more frequently than right lower quadrant exploration in the management of probable appendicitis. The improvement in diagnostic accuracy may be offset by an increased number of negative appendectomies resulting from nonvisualization and false-positive inflammation.
