title: Colonic retnetion of barium in the elderly after barium-meal examination and its treatment with lactulose.
abstract: Five cases of colonic retention of barium with severe constipation occurring in elderly patients after a barium-meal examination were seen in a two-year period and it is suggested that this complication may be unrecognized. Lactulose 50% (Duphalac) was an effective agent in inducing bowel evacuation in these patients, who were resistant to more generally used methods.
