An upper-gastrointestinal tract examination is usually performed in patients with obstructive jaundice, although the diagnostic accuracy is thought by many to be quite low. A prospective study was undertaken to determine whether the diagnostic accuracy of the gastrointestinal examination could be improved by the use of cineradiography. Sixty-one patients thought to have obstructive jaundice were studied by cineradiography. The diagnoses obtained were compared with clinical and pathological findings. The diagnosis of periduodenal carcinoma was correctly made or excluded for 50 patients, giving an accuracy level of 82%. These findings indicate that cineradiography provides a convenient means of complete recording of changes in the duodenum which may be analyzed in detail and at length, and which can result in a higher level of accuracy in the diagnosis of periduodenal carcinoma than is obtainable by conventional methods.
