[Efficacy of basic surgical diagnosis in acute abdominal pain].

This report describes a retrospective study concerning 314 patients suffering from acute abdominal pain admitted to the surgical emergency unit of Zürich University Hospital in 1992. Basic diagnostic work-up (history, physical examination, blood tests, sonography and abdominal X-ray) revealed the final diagnosis in 188 patients. Sonography was essential in 77 cases. Only 33 patients required additional examinations, such as CT-scan, gastroscopy or contrast X-rays. Ninety-three patients were discharged with a final diagnosis of "non-specific abdominal pain" (NSAP) after their symptoms had improved. A follow-up examination of these patients 6-18 months later resulted in a final diagnosis of somatic diseases in 8% of cases. This study demonstrated that the basic surgical diagnostics are efficient and reveal the final diagnosis with minimal delay. Abdominal sonography is the most important diagnostic tool in this context and should, therefore, be mastered and employed by the surgeon himself.
