Usefulness of a Combination of a 48-Hour Fasting and a Glucagon Tolerance Test Abstract #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.

#1699 Should the Selective Arterial Secretagogue Injection Test for Insulinoma Localization be Evaluated at 60 Seconds or At 120 Seconds?
Introduction: The selective arterial secretagogue injection (SASI) test is considered indispensable for an accurate insulinoma localization. The optimal timing of post-injection evaluation has not been established yet, as some studies recommend 60 seconds [SASI (60 sec)] while others support 120 seconds [SASI (120 sec)].

#91 Endoscopic ultrasound of 66 insulinomas
Introduction: Ultrasound is the virtual representation of the morphology of organs and tissues. Endoscopic ultrasound can be used in detailed scanning of pancreas and preoperative topical diagnostics of insulinomas. Insulinoma requires surgical treatment in all cases. This fact allows control of preoperative diagnostic methods.
