We performed transumbilical portal vein catheterization and sampled portal blood selectively to carry out immunoreactive insulin (IRI) analyses in a 7-month-old girl with hypoglycemia. The IRI concentration was highest in the mid-portion of the splenic vein. Although no tumor was found at surgery, 70 per cent of the caudal pancreas was resected above the superior mesenteric vein to a point determined by preoperative investigations. Pathologic examination of the resected specimen indicated nesidioblastosis. There have been no postoperative hypoglycemic symptoms. Our technique is efficacious in reaching a diagnosis of infantile hypoglycemia.
我们对一名7个月大的低血糖女童进行了经脐门静脉插管，并选择性采集门静脉血以进行免疫反应性胰岛素（IRI）分析。IRI浓度在脾静脉中部最高。尽管手术时未发现肿瘤，但根据术前检查确定的位置，在肠系膜上静脉上方切除了70%的胰腺尾部。切除标本的病理检查显示为胰岛细胞增殖症。术后未出现低血糖症状。我们的技术在诊断婴儿低血糖方面是有效的。
