Amylase thermolability as a screening test for pancreatic pseudocysts. 1978

L A Donaldson, and M J Brodie, and W B McIntosh, and S N Joffe

Amylase thermolability was determined by heating sera from control patients and patients with acute pancreatitis and pancreatic pseudocysts at 65 degrees C for 15 min. Normal serum amylase was 44 per cent thermolabile, but increased to 84 per cent thermolability during the hyperamylasaemia of acute pancreatitis, and returned to normal on resolution of the pancreatitis. In 9 patients with a pancreatic pseudocyst, although the total amylase level had almost returned to normal limits, 79 per cent of the amylase remained thermolabile. Amylase thermolability appears to be a simple screening test for pancreatic pseudocyst formation secondary to acute pancreatitis.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010181	Pancreatic Cyst	A true cyst of the PANCREAS, distinguished from the much more common PANCREATIC PSEUDOCYST by possessing a lining of mucous EPITHELIUM. Pancreatic cysts are categorized as congenital, retention, neoplastic, parasitic, enterogenous, or dermoid. Congenital cysts occur more frequently as solitary cysts but may be multiple. Retention cysts are gross enlargements of PANCREATIC DUCTS secondary to ductal obstruction. (From Bockus Gastroenterology, 4th ed, p4145)	Cyst, Pancreatic,Cysts, Pancreatic,Pancreatic Cysts
D010195	Pancreatitis	INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.
