Usefulness of a Combination of a 48-Hour Fasting and a Glucagon Tolerance Test
#1074
Introduction: The 72-hour fasting test is the gold standard for the diagnosis of insulinoma. However, the test can become a burden for both patients and medical staff and, shortening the duration of fast has been attempted. There are several reports on the high sensitivity of fasting test but only a few reports on its specificity. An insulinoma can be localized using invasive tests such as endoscopic ultrasonography and selective arterial secretagogue injection test. Therefore, insulinoma detection with high specificity may be needed to avoid unnecessary examinations.
Aim(s): The aim of this study is to evaluate the effectiveness of a combination of a 48-hour fasting and a glucagon tolerance test.
Materials and methods: Data were retrospectively collected from the inpatients who were suspected insulinoma between September 1992 and July 2014. These patients underwent a 48-hour fasting test followed by a glucagon tolerance test.
