Surgical management of insulinoma

Three patients with insulinoma have been presented. Accurate diagnosis, localization and multiplicity are possible employing angiography, sonography, CAT and insulin concentration determinations of specimens obtained by percutaneous, transhepatic simultaneous sampling of the portal, splenic and superior mesenteric veins. Meticulous exploration of the gland will permit enucleation rather than major resection to be a feasible solution and the operation of choice.
