PURPOSE: Computed tomography (CT) is the most appropriate imaging modality for the assessment of @entity697 at the emergency unit. The aim of this study was to determine the clinical outcome of the @entity1 presented first time with symptoms of @entity697 and low CRP values. METHODS: Two-hundred @entity1 , who presented with the symptoms of @entity697 and had CRP values under 150  mg/L, underwent abdominal CT examination on admission to Oulu University Hospital. The clinical parameters and radiological findings were compared in relation to clinical outcome both by means of univariate and multivariate analyses. RESULTS: Seventy-one (35.5  %) of the 200 @entity1 presented on admission with complicated @entity4436 . CRP values between 100 and 150  mg/L predicted complicated disease, but the mean values of CRP between @entity66 , 89  mg/ @entity23450 , and complicated disease, 101  mg/ @entity23450 , did not differ significantly. Free intra-abdominal fluid in CT was the only independent risk factor of the need for interventional therapy and treatment in the intensive care unit. Longevity of the @entity1 and free fluid in CT predicted significantly prolonged hospitalization. Mortality was 1  % and older @entity1 were significantly affected. The recurrence rate of @entity697 was 24  % (43/177) in the whole group and 18  % (23/129) after uncomplicated @entity4436 . CONCLUSIONS: Low CRP values do not reliably predict @entity66 in @entity1 presented first time at the emergency unit with @entity697 . We recommend that the need for abdominal CT is carefully evaluated according to the @entity1 's clinical status, always even when the CRP value is under 150  mg/L.
