    Abstract:
    BACKGROUND: Somatostatin (SST) is known for its inhibitory effect on the gastrointestinal tract. Transient lower esophageal sphincter relaxations (TLESR), low or absent LES pressure (LESP) and swallow-induced LES relaxations are the most important reflux mechanisms. METHODS: We have studied the effect of somatostatin on lower esophageal sphincter (LES) characteristics in man. Nine healthy volunteers participated in four experiments performed in random order and double-blind during continuous infusion of somatostatin (250 microg/h) or saline (control) under fasting and postprandial conditions. Esophageal motility was measured with sleeve manometry combined with pH metry. RESULTS: Under fasting conditions LESP was not influenced by somatostatin. Ingestion of the carbohydrate meal significantly (P < 0.01) decreased LESP. During continuous somatostatin infusion the postprandial decrease in LESP did not occur; LESP was even significantly (P < 0.05) increased over basal levels. Somatostatin did not significantly influence TLESR frequency, neither under basal conditions, nor postprandially. The residual pressure during swallow-induced LES relaxation was significantly (P < 0.05) increased by somatostatin. CONCLUSION: In humans somatostatin prevents postprandial reduction in LESP, does not affect TLESR, but inhibits swallow-induced LES relaxation.
