insulin hypoglycemia test
an infrequently used test to determine the completeness of vagotomy; after the surgery, insulin is administered to cause hypoglycemia; if vagotomy is complete, the acid output from the stomach following administration of insulin is substantially less than that before insulin administration; if the level is unchanged, incomplete vagotomy is likely. Complications of hypoglycemia are such that the test largely has been abandoned.
