[The role of real-time sonography in the differential diagnosis of acute appendicitis and in the detection of post-appendectomy complications].

110 urgent sonography were performed on 101 patients with suspected acute appendicitis and on subsequent 26 patients 33 echography with suspected postappendectomy abscess. Although according to a few publications in connection with acute appendicitis there are characteristic sonographic signs, the authors didn't find any typical structures at patients having non-complicated appendicitis. But at perforated appendicitis and periappendicular abscesses the fluid collection was frequently very well visualizable and the periappendicular infiltration was detectable as well. The differentation between infiltration and abscess is difficult, often unsuccessfull. The authors confirm the high sensitivity of sonography in the detection of postappendectomy intraabdominal abscesses, similarly to other abscesses of unrelated origin. They emphasize the differentialdiagnostic aid of sonography, if the clinical symptoms are atypical or the signs of acute appendicitis are imitated by other disease.
