Abstract
Recent experience with three successfully resected cases of insulinoma, a relatively rare pancreatic endocrine tumor, is presented here. Cases 1 and 2 were adults. Tumors in these cases were localized by percutaneous transhepatic portal catheterization (PTPC). Post-surgical histological examination of the specimens from Case 2 revealed the presence of multiple microlesions around the main lesion, which suggested that the excision not only of the apparent tumor but of a certain amount of pancreatic tissue might also be necessary in some cases. Because the treatment of choice for insulinoma is adequate resection, localization is important. In pediatric cases such as Case 3, preoperative medical management for the regulation of blood sugar, preceding localization, is necessary and not less important.
