摘要
本文报告胰岛素瘤8例,其中男5例女3例,年龄28～50岁,主要症状为反复发作性意识丧失,进食或补糖后缓解,最低空腹血糖1.2mmol/L。8例中2例结合临床诊断恶性。文内对发病情况、临床诊断、精确定位、组织学改变和内科治疗进行了讨论。近年 CT 诊断功能性胰岛素瘤的准确性达到77.4%,但小于2cm 的肿瘤仅在增强扫描时见到。肝穿门静脉插管分段采血胰岛素分析定位胰岛素瘤,其手术相符率达81.2%。术后高胰岛素血症常口服氯苯甲噻二嗪。
Eight cases of insulinoma were reported,including 5 men and 3 women;2 casesof the series were malignant.The patients ranged from 28 to 50 years of age.Thechief complaint was recurrent attacks of unconsciousness in a fasting state.The sym-ptoms could be relieved following ingestion of food or correction of hypoglycemia.The lowest fasting glucose level was 1.2 mmol/L.The incidence,the clin(?)cal diagno-sis,the accurate localization,the histopathological changes and medical treatmentwere discussed.In recent years accuracy of CT in the diagnosis offunctioning tumorsof the pancreas has reached 77.4 per cent,but tumors smaller than 2 cm could onlybe seen on enhanced CT scan.Localization of insulinomas with the transhepaticportal catheterization for insulin analysis was 81.2% consistent with the result foundin operation.Hyperinsulinemia persisted after surgery,oral diazoxide was usuallygiven.
