INTRODUCTION Hyperinsulinism is the most common cause of recurrent and persistent hypoglycemia in infancy and childhood. Causes can include nesidioblastosis, pancreatic islet cell tumors such as insulinoma, and associations with multiple endocrine neoplasia syndromes. Although new, improved imaging techniques have allowed for more precise preoperative localization of insulinomas, the differenti...

Five cases of malignant insulinoma and 2 cases of benign insulinoma were studied lipid-chemically. Tissues were collected by surgical operation or biopsy under peritoneoscopy. The total lipid was extracted from each tissue, and one part of each total lipid was separated into phospholipid, triglyceride and other lipid fractions by a thin-layer chromatography (TLC) on silica gel. The fatty acid c...

Prevention of hypoglycaemia may sometimes be difficult in the operative period of insulinoma when parenteral volume overload is contraindicated due to severe cardiac failure. We investigated the effects of octreotide on hypoglycaemia during operations in two patients with insulinoma, one of whom had severe congestive heart failure. We found no hypoglycaemic values by using octreotide 100 microg...

A 7-year-old castrated male German shepherd dog was presented with a 10-day history of intermittent lethargy, weakness and episodic seizures. Laboratory findings after admission revealed hypoglycaemia and hyperinsulinaemia. Provisional diagnosis of insulinoma was made based on the presence of concurrent hypoglycaemia and elevated insulin level. In exploratory laparotomy a small nodular mass was...

A cuse with single tenign insulinoma which was located in trc tail af pancreas is presented. It should be pinte out that a diagnosis of organic hypeinsulini::m may be difficult lo establish becau­se of the aljpictl symptoms and signs. Whipple triad. laboratory, angiographv are important for diagnsis. Tle treatment of choice is early surgery with removal Df insulinoma. However if no tumor is fou...

CONTEXT AND OBJECTIVE Arterial stimulation and venous sampling (ASVS) is an important technique for localizing insulinoma. The principle behind ASVS is that insulin secretion is promoted from insulinoma cells by the injection of calcium into the insulinoma-feeding artery. However, the mechanism for ASVS-induced insulin secretion remains unclear. Both insulinoma and familial hypocalciuric hyperc...

Little information is available regarding triple-phase computed tomography (CT) of canine pancreatic insulinoma. A few case reports with small numbers of cases have indicated that hyper-attenuation in the arterial phase was a common finding on multi-phasic CT in dogs with insulinoma. Our purpose was to clarify the characteristic findings of dogs with insulinoma on triple-phase CT. Nine dogs wit...
