Vague gastrointestinal complaints in children have always been a problem for the pediatrician. With the idea that these symptoms might occasionally be associated with disease of the gallbladder we have often desired to attempt cholecystography, but, owing to the toxic effects which at times follow the use of iodophthalein sodium for adults, it was felt that the use of this medium might be a dangerous procedure, especially for small persons.
