To confirm the diagnosis of gastrinoma a series of blood tests must be made. One of those tests is the serum gastrin level, which is the most reliable test for patients with gastrinoma. The normal levels of gastrin are 150 pg/mL ( > 72.15 pmol/L); therefore elevated levels of > 1000 pg/mL (> 480 pmol/L) would establish the diagnosis of ...

[13] Cirrhosis is found in only about 50% of people with MASLD and with liver cancer, so that liver cancer and cirrhosis are not always ...
Hereditary pancreatitis (HP) is an inflammation of the pancreas due to genetic causes. It was first described in 1952 by Comfort and Steinberg [1] but it was not until 1996 that Whitcomb et al[2] isolated the first responsible mutation in the trypsinogen gene (PRSS1) on the long arm of chromosome seven (7q35). The term "hereditary pancreatitis ...
Somatostatinoma. Somatostatinomas are a tumor of the delta cells of the endocrine pancreas that produces somatostatin. Increased levels of somatostatin inhibit pancreatic hormones and gastrointestinal hormones. Thus, somatostatinomas are associated with mild diabetes mellitus (due to inhibition of insulin release), steatorrhoea and gallstones ...
