Radiation exposure was studied in 327 patients undergoing endoscopic retrograde cholangiopancreatography, or endoscopic papillotomy taking into account fluoroscopy time and incident area exposure. The mean fluoroscopy time was 238 +/- 152 seconds and the incident area exposure 3,730 +/- 2,790 R X cm2. These results were compared with standard exposures in upper GI series and colon examinations as found in the literature.
对327例行内镜逆行胰胆管造影术或内镜乳头切开术的患者进行了辐射暴露研究，研究时考虑了透视时间和入射面积暴露情况。平均透视时间为238±152秒，入射面积暴露为3730±2790伦琴·平方厘米。将这些结果与文献中报道的上消化道系列检查和结肠检查的标准暴露情况进行了比较。
