The aim of the study was to calculate radiation doses for patients and staff during interventional Endoscopic retrograde cholangiopancreatography (ERCP) procedures. Patient age (A), kerma-area product (KAP), fluoroscopy time (T) and total number of films (F) were collected for 157 interventional ERCP procedures. One endoscopist (>10 y of experience) monitored using a thermoluminescent dosemeter worn over the lead apron performed the ERCPs. Median (range) KAP was 3.1 Gy cm(-2) (0.1-106.7 Gy cm(-2)). Median (range) A, T and F were 72 y, 2.6 (0.2-26.0) min and 2 (1-4) images, respectively. No correlation was observed between KAP and A, T or F. Monthly endoscopist dose was negligible due to the use of lead apron, collar and two lead-articulated ceiling mounted shields. The endoscopist dose is minimal when using appropriate protective measures. Patient doses showed large variation that has to be further investigated.
本研究的目的是计算介入性内镜逆行胰胆管造影（ERCP）手术期间患者和工作人员所接受的辐射剂量。收集了157例介入性ERCP手术的患者年龄（A）、比释动能面积乘积（KAP）、透视时间（T）和胶片总数（F）。由一名经验超过10年的内镜医师使用佩戴在铅衣外的热释光剂量计进行监测来实施ERCP手术。KAP的中位数（范围）为3.1 Gy cm⁻²（0.1 - 106.7 Gy cm⁻²）。A、T和F的中位数（范围）分别为72岁、2.6（0.2 - 26.0）分钟和2（1 - 4）张图像。未观察到KAP与A、T或F之间存在相关性。由于使用了铅衣、铅颈围和两个可活动的天花板悬挂式铅屏蔽，内镜医师的月度剂量可忽略不计。采取适当的防护措施时，内镜医师所受剂量极小。患者剂量显示出较大差异，有待进一步研究。
