[Influence of somatostatin (GIF) and human gastrin I on the lower esophageal sphincter].
The influence of gastrin and somatostatin on the lower esophageal sphincter was investigated in 10 metabolically healthy volunteers and one patient with Zollinger-Ellison syndrome. It could be shown that only unphysiologically high concentrations of gastrin produced a rise in pressure in the lower esophageal sphincter, while somatostatin has neither an effect on the lower esophageal sphincter pressure, nor is it able to inhibit the pharmacologic effect of exogeneous gastrin administration. The results emphasize that gastrin and somatostatin have no influence on the tone of the lower esophageal sphincter.
