The accuracy of operative cholangiograms can be increased by radiomanometry. This study identified 17 patients among 198 studied whose choledocholiths would have likely been missed by routine cholangiography. These are almost invariably small stones the fate of which would be conjectural if left behind. In the present study, if the cholangiogram was negative and the passage pressure within normal limits, calculi were seen only once. If the cholangiogram was positive for choledocholithiasis and the passage pressure elevated, stones were almost invariably found (95 per cent). Such accuracy cannot be expected from either roentgenography alone or determination solely of pressure relationships.
通过胆道测压法可提高术中胆管造影的准确性。本研究在198例接受研究的患者中识别出17例患者，其胆总管结石很可能会被常规胆管造影遗漏。这些几乎都是小结石，如果遗留下来，其转归将难以推测。在本研究中，如果胆管造影为阴性且通过压力在正常范围内，结石仅出现过一次。如果胆管造影显示胆总管结石阳性且通过压力升高，几乎总能发现结石（95%）。单独的X线摄影或仅测定压力关系都无法达到这样的准确性。
