title: [Clinical significance of ambulatory intraesophageal bilirubin monitoring in diagnosis of gastroesophageal reflux].
abstract: To evaluate the usefulness of ambulatory intraesophageal bilirubin monitoring in the diagnosis of GER, 38 patients with reflux symptoms and 7 controls were studied, using Bilitec 2000. The % time of bilirubin and acid reflux was less than 5% in all of the controls. In 3 patients of NUD, % time of acid reflux was less than 5%, but that of bilirubin was more than 8% in 2 patients. Acid reflux was found only in 1 of 4 patients who had a history of subtotal gastrectomy, but abnormal bilirubin reflux was found in all of 4 patients. In the other 31 patients, a significant difference was found in the % time of bilirubin reflux by the severity of reflux esophagitis, whereas this difference was not found in that of acid reflux. Intraesophageal bilirubin monitoring is useful in the diagnosis of GER and is essential in patients with hypochlorhydria or minimal reflux.
