For diagnosis of pancreatic exocrine dysfunction and gastrinoma
Used in the diagnosis of pancreatic dysfunction or gastrinoma (stomach cancer), secretin is a hormone produced in the S cells of the duodenum in response to low local pH. It stimulates the secretion of bicarbonate from bicarbonate producing organs(liver, pancreas, Brunner's glands) when the pH drops below a set value. This helps neutralize the gastric acid entering the duodenum from the stomach. It also inhibits acid secretion from the stomach by reducing gastrin release from the G cells of the stomach.
Mechanism of Action
Secretin binds to the secretin receptor found on the lining of S cells in the duodenum and G cells in the stomach. Binding leads to the secrection of bicarbonate or the reduction of the secretion of gastrin. Properly functioning organs (duodenum, pancreas and stomach) should be responsive to this hormone
