To reassess 24-hour esophageal monitoring and determine if shorter time periods might retain its diagnostic benefits, we studied 16 gastroesophageal reflux (GER) patients and eight controls. Esophageal pH monitoring was performed for 24 hours, with patients in an upright position during the day and supine when retiring. During the 24-hour pH monitoring period, the mean percentage time that pH was less than 4.0 in GER patients, 13.2% +/- 2.9% (SEM), was significantly higher than in normal… CONTINUE READING
