title: [Sonography in suspected appendicitis: a decisive factor in diagnosis and therapy? Results of a prospective study of 669 patients].
abstract: The appendectomy-rate in the Federal Republic of Germany is decreasing. German surgeons have begun to refuse appendectomy if there are no signs of acute inflammation. Preoperative assessment of patients with right lower quadrant pain has acquired new significance. The authors report on 2 years of experience with routine use of high-resolution ultrasonography in 669 cases of suspected acute appendicitis. Only 101 patients (= 15.1%) turned out to be suffering from acute appendicitis. Ultrasonography evaluation was found to have a sensitivity of 84.2%, a specificity of 96.8% and an overall accuracy of 94.9%. Ultrasonography was also useful in detecting mimicking diseases of acute appendicitis. Sonography should help to rule out severe disease in the frequent cases of functional abdominal pain.
