探讨ＥＲＣＰ对梗阻性黄疸的病因诊断和并发症的防治。对临床诊断梗阻性黄疸的２２５例患者做ＥＲＣＰ检查，发现１．梗阻性黄疸常见病因为肿瘤和总胆管结石。２．５０岁以上患者肿瘤较常见，主要为总胆管癌、壶腹周围癌和胰腺癌。３．对总胆管结石的诊断，ＥＲＣＰ较腹Ｂ超准确，诊断准确率分别为９４．６％和２５．９％，二者比较差异极显著（Ｐ＜０．０１）。４．化脓性胆管炎是ＥＲＣＰ最严重的并发症，对黄疸严重的患者，采取（１）先做ＰＴＣ；（２）把６０％泛影葡胺稀释为３０％；（３）在造影剂中加入庆大霉素。可明显减少并发症。因此，ＥＲＣＰ诊断梗阻性黄疸是一种既准确又安全的方法。
To investigate the etiological diagnosis and prevention and treatment of obstructive jaundice by ERCP. ERCP examination of 225 patients with clinically diagnosed obstructive jaundice found 1. Common causes of obstructive jaundice are tumors and total bile duct stones. 2.50 years of age patients with cancer more common, mainly for cholangiocarcinoma, periampullary cancer and pancreatic cancer. 3. The diagnosis of total bile duct stones, ERCP compared with abdominal B ultra-accurate, diagnostic accuracy was 94.6% and 25.9%, the difference was significant (P <0.01). 4. Suppurative cholangitis is the most serious complication of ERCP. Patients with severe jaundice should be treated with (1) first PTC; (2) 60% of diatrizoate diluted to 30%; and (3) Taicangmycin. Can significantly reduce complications. Therefore, ERCP diagnosis of obstructive jaundice is an accurate and safe method.
