[Results of ultrasonic tomography in the diagnosis of gastrointestinal diseases].
A thickening of the stomach or intestinal wall as a result of neoplastic or inflammatory infiltrations can be principally recognized by sonography as a "Cocarde phenomen". The question of the accuracy of ultrasonic tomography in the recognition of infiltrative diseases of the gastrointestinal tract has been examined in a prospective study. 80 patients who were suspected of having such a disease were sonographed, using the real-time method. The diagnose were verified by an adequate comparative method, by surgery or autopsy. An infiltrative gastrointestinal disease was correctly diagnosed by sonography in 42 cases, including nine cases of gastric carcinoma and of 27 colon carcinoma. Two patients were suffering of Crohn's disease, and in the remaining four cases the final diagnoses were bulbitis, Ménétrier's disease, diverticulitis and penetrating ulcus ventriculi, respectively. In 27 cases an infiltrative gastro-intestinal disease was correctly exclused by sonography. Ultrasonic examination wrongly produced a negative diagnosis in five cases and a positive in six. Thus, the efficiency of the examination was 0,86, the sensitivity 0,89 and the specifity 0,82. Ultrasonic tomography should therefore be assigned a major place in gastrointestinal diagnostics, too. It could point the way in many cases. It is not possible, however, to exclude a disease by means of sonography.
