We have recently tested the response to a bolus injection of secretin and cholecystokinin (pancreozymin) in a patient with high serum levels of VIP (range, 200 to 600 pg/ mL) and the pancreatic cholera syndrome.
This patient had malignant carcinoid cells recovered by needle aspiration from hepatic nodules and a step-up in serum VIP levels across the hepatic
