Abstract
Objective:
To establish a method for bocative diagnoses of insulinoma,
Method:
Five patients with insulinoma were given locative diagnoses by using ASVS methods which mean injecting calcium stimulatant into pancreatic supplying arteries and then taking blood specimens from henatic vein to gauge the insulin levels. Six samples, each 2 ml, were taken before and 30, 60, 90, 120, 180 seconds after the injection.
Results:
If the peak of blood-insulin level was twice or higher than the basic level, the tumor was located in the domain. These results were confirmed operatively in all the five cases.
Conclusion:
ASVS is an accurate technique to localize insulinoma.
