ABSTRACT: Somatostatin and somatostatin analogues are considered very useful for the treatment of hormone producing tumors and acute variceal bleeding. They have also been proposed for the treatment of acute pancreatitis and for the prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis although clinical trials have failed to show any efficacy. The authors report the case of a 45-year-old man, recently diagnosed of acromegaly, which developed an acute pancreatitis shortly after his first injection of lanreotide autogel. The patient developed a severe dilatation of his hypocontractile gallbladder with distension of the intra and extrahepatic biliary ducts, the choledochus and the main pancreatic duct, without lithiasis or other abnormalities at the papilla, which resolved spontaneously in a month. We consider that lanreotide most likely induced a functional spasm of the Sphincter of Oddi, with impairment of the biliary-pancreatic outflow, leading to an acute pancreatitis, and review the literature concerning this drug related pancreatitis.
