近年来胰岛素瘤诊治技术有不少进展。测定周围静脉血IRI/G值比单测IRI或G值更有诊断意义;测定门静脉血IRI对确诊胰岛素瘤和鉴别低血糖的病因更重要;经皮经肝穿刺门静脉取血测定IRI有很好的肿瘤定位作用;细针穿刺涂片细胞学检查比冰冻切片创伤小、需时短;术中用IRI快速测定法监测肿瘤组织是否完全切除,优于血糖监测;避免胰腺组织过多创伤是预防急性坏死性胰腺炎和降低死亡率的重要措施,正确处理瘤床创面则是减少术后并发胰瘘的关键。
In recent years, there have been many advances in the diagnosis and treatment of insulinoma. Determination of peripheral venous blood IRI/G values is more diagnostic than single measurement of IRI or G values; determination of portal venous blood IRI is more important for the diagnosis of insulinoma and the identification of the cause of hypoglycemia; percutaneous transhepatic portal vein blood determination IRI is very good The role of tumor localization; fine needle aspiration cytology cytology than frozen section wounds less time-consuming; intraoperative use of IRI rapid assay to monitor whether the tumor tissue completely removed, better than blood glucose monitoring; avoid excessive pancreatic tissue injury is to prevent Acute necrotizing pancreatitis and important measures to reduce mortality, correct treatment of tumor bed wounds is the key to reduce postoperative pancreatic fistula.
