Should the Selective Arterial Secretagogue Injection Test for Insulinoma Localization be Evaluated at 60 Seconds or At 120 Seconds?

#1699

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)].

Aim(s): To determine the optimal timing for SASI test evaluation for insulinoma localization.

Materials and methods: Thirteen patients with surgically proven insulinoma were studied retrospectively. For the SASI test, immunoreactive insulin (IRI) was determined at baseline, and after 30, 60, 90, and 120 seconds after calcium gluconate injected. The localization detection ability of SASI (60 sec) and SASI (120 sec) was compared.
