    Abstract:
    BACKGROUND: In view of the threat that comes with an acute abdomen, it is of major importance that diagnostics are executed quickly and efficiently. In the course of this two tendencies can be differentiated: 1) general use of complex examination (e.g. CT, MRT) of all potential patients and 2) step-by-step-diagnostics with advanced diagnostics as and when required. MATERIAL AND METHODS: A total of 444 patients with an acute abdomen as admission diagnosis were investigated. All data were evaluated prospectively and analyzed retrospectively. All patients had the same basic diagnostics consisting of aclinical history, clinical examination, laboratory examination, abdominal sonography and x-ray overview images. These examinations were supplemented when required by advanced measures, such as CT, colon enema with contrast fluid, endoscopic examination and diagnostic laparotomy. RESULTS: Three different disease groups of unequal diagnostic need could be identified. The first group, presented in the form of an appendicitis showed that in 80% of all patients a basic diagnosis was sufficient. Advanced examination such as CT affected 14%. The negative appendectomy rate amounted to 8%. Other diseases belonging to the first group were ileus, acute biliary diseases, perforation etc. In the second group presented in the form of a diverticulitis, an advanced radiological examination was required in 84% of all cases. Similar results are also expected in cases of pancreatitis. In the third group presented in the form of coprostasis, inflammatory etiology was found in 39% of all secondary diseases. However the symptoms became clinically apparent after treatment of the coprostasis. In this group a basic diagnosis was satisfactory in 84% of cases, however, a diagnostic laparotomy was inevitable for 3% of these patients. CONCLUSION: Generally step-by-step diagnostic approach has proven itself to be efficient. For 80% of all patients it makes advanced diagnostic measures unnecessary. The exceptions are diseases in which it is necessary to know not only the diagnosis but also the disease stage. In these cases (e.g. pancreatitis, diverticulitis etc.) advanced diagnostics should be pursued from the onset. The necessity of a diagnostic laparotomy has lost importance for 1% of all patients.
