Oral cholecystography and ultrasonography of the gallbladder were performed in 190 patients with the aim of diagnosing gallstones. At surgery gallstones were found in 23 patients and a roundworm in 1 patient. The results obtained with the two methods are comparable. Since neither radiation nor contrast agents are employed in ultrasonography, it is suggested that this be regarded as the primary special examination in the diagnosis of gallstones.
