Abstract
Whether there was any relationship between the presence of bile in the stomach at endoscopy and the nycterohemeral variations of the gastric pH was investigated. Endoscopy and 24 h gastric pH monitoring with radiotele-pHmetry were performed in 38 patients. These patients were then divided into 2 groups according to the color of the mucous lake at endoscopy: group A (15 patients) in which there was a clear mucous lake and group B (23 patients) in which a bilious mucous lake was found. In group A, spontaneous alkalinizations (SA) were uncommon and almost always lasted < 30 min. In group B, SA were more frequent and more prolonged (P < 0.01), especially those lasting < 30 min (P < 0.001). In this group, the number and duration of SA were significantly higher during the night. Duodenogastric reflux may be responsible for the SA observed in patients with a bilious mucous lake. This hypothesis needs further confirmation especially concerning the analysis of the gastric contents during the periods of alkalinization.
