[Octreotide in the prevention of hyperamylasemia following ERCP (a controlled multicenter study)]

The aim of the multicentric trial was to study the effect of octreotide (Sandostatin) on the rise of pancreatic amylase in the serum after ERCP based on a large number of patients. The study was carried out in a prospective random manner in 2102 patients in 11 endoscopic centers. Patients in the treated group received 0.1 mg octreotide acetate, and those of the nontreated (control) group received isotonic sodium-chloride subcutaneously before the ERCP and 45 minutes after. Serum amylase and blood sugar were checked before the endoscopic procedure, 6 and 24 hours later. Out of the total number of patients involved, data of 1199 patients (599 in the treated group, and 600 in the control group) were evaluated. Octreotide diminished the percentual increase of serum amylase levels following ERCP. However, the frequency of hyperamylasaemia was decreased only after in patients with chronic obstructive pancreatitis or in such patients after endoscopic sphincterotomy. The peak serum level of blood sugar was higher in the treated group compared to the controls. There was no difference in the clinical symptoms following ERCP between the two groups.

the prophylactic use of long-acting somatostatin may diminish the frequency of hyperamylasemia after ERCP in patients with chronic obstructive pancreatitis or in those patients who subsequently underwent EST.
