The influence of pancreatic duct ligation (PDL) on gastric secretion was investigated in dogs with a Heidenhain pouch. A test meal was given to the dogs before PDL, and following PDL the dogs were administered with the test meal mixed with pancreatic enzymes and with the test meal alone in succession. The response to the test meal were examined in the control period and every week for a period of 1 to 6 weeks following PDL to identify the changes in gastric acid secretion, serum gastrin levels, immunoreactive glucagon (IRG) levels and immunoreactive insulin (IRI) levels. Gastric acid secretion in response to food stimulation markedly increased after PDL. However, the acid secretion was significantly inhibited by the administration of pancreatic enzymes. Serum gastrin levels began to increase from the second week and continued to increase until the sixth week after PDL, revealing no effect of pancreatic enzymes. IRG levels also increased following PDL, particularly in cases administered with pancreatic enzymes. IRI levels were higher at the first week of PDL than before PDL, but tended to decrease thereafter. It is assumed that gastric hypersecretion after PDL would have complicated relations with IRG and gastric inhibitory polypeptide (GIP), as well as with antral gastrin.
