Hypotonic cholangiography was performed with intravenous glucagon in 12 patients who demonstrated complete nonspecific obstruction of the distal common bile duct during postoperative T-tube or transhepatic cholanglography. In 8 cases (67%), a diagnostic result was obtained. Abolition of smooth-muscle spasm at the choledochal sphincter by glucagon-induced hypotonia appears to be a useful adjunct to roentgenography of the bile ducts.
对12例在术后T管造影或经肝胆管造影时显示胆总管远端完全性非特异性梗阻的患者，采用静脉注射胰高血糖素进行低张胆管造影。8例（67%）获得了诊断结果。胰高血糖素诱导的低张状态消除胆总管括约肌平滑肌痉挛，似乎是胆管X线造影的一种有用辅助手段。
