The effect of ethanol with a meal on the mucosa of the stomach and duodenal bulb.
The effect of ethanol together with a meal on the mucosa of the stomach and duodenal bulb was studied in nine healthy volunteers. The pre-study gastroscopy was performed after an overnight fast. Two to four weeks later the volunteers drank 72-136 g (mean 111.2 +/- 18.3 SD) alcohol together with a meal. They underwent endoscopy again on the following morning. The endoscopic and histological changes were evaluated by scoring the lesions (0-4). Alcohol caused slight to moderate endoscopically detected changes in the stomach of seven volunteers, the difference being statistically almost significant (p congruent to 0.05) in the case of haemorrhagic lesions. In two subjects slight hyperaemia was seen in the duodenal bulb. The histological study did not reveal significant changes after alcohol drinking. The bile acid concentrations of the gastric juice did not change after drinking. It is concluded that ethanol with a meal causes only slight changes in the mucosa of the stomach, haemorrhagic ones being the most prominent.
