    Notes: Abstract In order to define the clinical significance and the need for further clinical work-up in patients where abnormalities of the stomach or bowel are found by ultrasound, we performed a prospective study on 100 patients with such findings. Of all patients, 35% were found to have a malignant tumor, 73% had a diagnosis as made by reference methods which was probably (18%) or definitively (55%) related to the US finding. Eighteen percent had definitive false positive findings, in 9% no final diagnosis was obtained. Thus, a positive predictive value of 80% was calculated for the US finding of a mass or a target sign related to bowel or stomach in US. The positive predictive value was lowest for target signs related to the bowel (75%) and highest for bowel conglomerates (100%). Patients with target signs of the stomach, bowel conglomerates, or masses were more likely to have malignant disorders (72%) than those with target signs related to the bowel (16%). We conclude from this study that the ultrasound finding of a target sign or a mass related to stomach or bowel has a high clinical relevance and should in any case worked up by appropriate investigations when clinical consequences are possible.

    Notes: Abstract Fifty consecutive patients with acute pancreatitis were assessed with respect to a biliary origin of the disease. Endoscopie retrograde cholangiopancreaticography, surgery, and autopsy were used to define biliary pancreatitis. Ultrasound, computed tomography, and several laboratory tests (SGOT, SGPT, alkaline phosphatase, and bilirubin) were analyzed for their ability to detect a biliary origin of the disease. Ultrasound and computed tomography could not reliably make the diagnosis in the 10 patients found to have biliary disease. Receiver-operator-characteristic curves revealed that none of the laboratory tests assessed had sufficient sensitivity and specificity to determine the diagnosis, although all tests showed higher mean values in biliary pancreatitis. SGPT gave the best discrimination (positive predictive value 53%, negative predictive value 94%, cut off 40 Units/liter). Therefore, initial ERCP is suggested for a reliable diagnosis of biliary origin of acute pancreatitis.
