ABSTRACT
BACKGROUND:
The effect of native somatostatin on Sphincter of Oddi motility still remains controversial. Sphincter of Oddi inhibition was demonstrated at manometry in patients in the acute phase of alcoholic pancreatitis. Other investigators showed marked somatostatin-induced impairment of bile flow by hepato-biliary scintigraphy.AIM:
Aim of the study was to determine the effects of therapeutical doses of exogenous somatostatin on Sphincter of Oddi motility. PATIENTS ANDMETHODS:
We studied eight patients (two men, six women, age 18-42), in the quiescent phase of idiopathic recurrent pancreatitis. We directly studied Sphincter of Oddi motility by perendoscopic manometry and, indirectly, secretin-stimulated pancreatic juice outflow by Ultrasound-Secretin test. The two tests were repeated before and after somatostatin infusion.RESULTS:
Manometry was performed in two patients. After 250 microg somatostatin bolus the sphincter showed an increase of motor activity. At Ultrasound-Secretin test mean diameters were significantly larger at 40-60 min evaluation intervals during 250 microg/h somatostatin infusion as compared to saline infusion, showing a delayed pancreatic duct emptying.CONCLUSIONS:
Acute administration of somatostatin seems to induce an excitatory effect on Sphincter of Oddi motility, with impaired pancreatic outflow in patients in the quiescent phase of recurrent pancreatitis.
