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.
与其他成像方法相比，内镜超声是术前定位胰岛素瘤的最佳方法。此外，阳性结果可进一步确诊内分泌疾病，尤其是在考虑口服降糖药所致人为低血糖的鉴别诊断时。然而，必须始终考虑到内镜超声成像可能会出现假阳性和假阴性结果，并且内镜超声成像所获得结果的质量在很大程度上取决于检查者的经验。如今，内镜超声成像在胰岛素瘤诊断中的一个重要问题是手术策略的规划。如三个病例所示，内镜超声成像能够识别适合腹腔镜微创手术的患者。
