Postprandial osmotic and fluid changes in the upper jejunum after truncal vagotomy and drainage in man.
The changes in osmotic pressure and the degree of marked dilution in the jejunal lumen after a hypertonic meal, have been studied in patients after truncal vagotomy and drainage, with and without diarrhoea, using an intraluminal intubation technique. The results suggest that neither the emptying of a hyperosmotic load from the stomach, nor its subsequent dilution in the jejunum have an important role in post-vagotomy diarrhoea.
