本文对19例梗阻性黄疸患者做了GTT与IRI,结果胆总管结石与无胰腺转移之胆管癌均表现糖耐量减低即低抛物线型,△IRI/△BS(30分)值正常。胰腺癌(7/8)与有胰腺转移之胆管癌里糖尿病型曲线,即高抛物线型和直线上升型,△IRI/△BS(30分)值明显降低,与前者有明显差异。GTT和IRI与影像学检查ERCP、PTC等相结合,可提高诊断率,并在影像学鉴别困难时具有重要之辅助诊断价值与术前预测手术切除性之作用。
In this paper, GTT and IRI were performed in 19 patients with obstructive jaundice. Both choledocholithiasis and cholangiocarcinoma without pancreatic metastasis demonstrated low glucose tolerance, ie, low parabolic type, and △IRI/△BS (30 points) were normal. The diabetes-type curve of pancreatic cancer (7/8) and cholangiocarcinoma with pancreatic metastasis, ie, hyperparabolic and straight-line rise, △IRI/△BS (30 points) values significantly decreased, which was significantly different from the former. The combination of GTT and IRI with imaging examinations such as ERCP and PTC can increase the diagnostic rate, and have an important auxiliary diagnostic value in predicting the difficulty of imaging and preoperative prediction of resection.
