Abstract
Compared to other imaging methods, endoscopic ultrasound is the best procedure to localize insulinomas preoperatively. Positive finding furthermore confirms endocrinological diagnosis, especially considering the differential diagnosis of hypoglycaemia factitia by oral antidiabetics. However, it always has to be considered that endoscopic ultrasound imaging may reveal false positive and false negative results, and quality of the findings obtained by endoscopic ultrasound imaging depends to a large extent on the examiner's experience. An important issue of endoscopic ultrasound imaging in insulinomas nowadays is planning surgical strategy. As illustrated by three cases, endoscopic ultrasound imaging enables to identify patients that qualify for laparoscopic, minimal invasive surgery.
Key words
