Limitations of EUS include poor differentiation between the pancreatic tumor and insulinoma diagnostico peripancreatic insulinoma diagnostico nodes, invasiveness, sedation requirement, operator dependency and a lack of universal availability.

When preoperative noninvasive studies fail to localize the tumors, invasive studies are utilized, which are often more successful. One of the most recommended techniques for localizing insulinomas is intraoperative ultrasonography IOUS in insulinoma diagnostico with intraoperative palpation carried out by an experienced surgeon.
