小的胰岛素瘤可能无法通过动脉造影术或胰腺触诊发现。然而，可以通过在几个部位的静脉流出物中检测到高胰岛素水平的点来识别它们，这些静脉流出物是在开腹时通过脾静脉和门静脉插管或通过经皮经肝途径采集的。通过插管技术进行诊断，可以只切除胰腺中含有肿瘤的那部分(一个患者是头部，另一个是胰腺身体)。改进的本地化是计划手术的关键，通常消除了在剖腹手术前进行漫长的内科治疗试验的需要。
Small insulinomas may be undetectable by arteriography or palpation of the pancreas. They can be identified, however, by the point at which high insulin levels are detected in the venous effluent sampled at several sites by catheterisation of the splenic and portal veins at laparotomy or via the percutaneous transhepatic route. Diagnosis by catheterisation techniques made it possible to resect only that part of the pancreas containing the tumour (in one patient the head and in another the body of the pancreas). Improved localisation is essential in planning an operation, and often removes the need for lengthy trials of medical therapy before laparotomy.
