The ERCP procedure requires the use of fluoroscopy with the subsequent exposure to ionizing radiation. The doses received by patients, physicians and assistants in the endoscopy have never been recorded in our area. This analysis describes the findings of the MIRED_Uy study (measuring radiation in digestive endoscopy in Uruguay). Objective. To determine radiation exposure received by patients, physicians and assistants during ERCP.
Data were collected from 33 procedures conducted by four endoscopists, supported by endoscopy assistants. All staff took basic radiation-protection measures. The magnitudes measured were the kerma area product (KAP) for the patient and the effective dose (E) and the equivalent doses in hand (HM) and lens of the eyes (HC) for the operators.
Mean value for PKA was 24 Gy.cm2 (range: 0.04-71) equivalent to 312 chest x-rays. The mean fluoroscopy time was 2.3 minutes (range: 0.45 a 5.70 minutes). The E mean per procedure was 3.69, 5.14 y 3.69 muSv, for physician, first and second assistant respectively. The dose in hand for the physician was 19.4 muSv and the dose in lens was 7.94 muSv.
The first results of measuring ERCP radiation doses in Uruguay are presented These procedures expose the patient and staff to measurable radiation doses, which should be taken into account to minimize their risks.
内镜逆行胰胆管造影（ERCP）操作需要使用荧光透视，随后会接触到电离辐射。在我们地区，患者、医生和助手在内镜检查过程中所接受的剂量从未被记录过。本分析描述了MIRED_Uy研究（乌拉圭消化内镜辐射测量）的结果。目的：确定患者、医生和助手在ERCP过程中所接受的辐射暴露。
收集了由四名内镜医师在内镜助手协助下进行的33例操作的数据。所有工作人员都采取了基本的辐射防护措施。测量的量值包括患者的比释动能面积乘积（KAP）以及操作人员的有效剂量（E）、手部的当量剂量（HM）和眼部晶状体的当量剂量（HC）。
PKA的平均值为24 Gy.cm²（范围：0.04 - 71），相当于312次胸部X光检查。荧光透视的平均时间为2.3分钟（范围：0.45至5.70分钟）。每次操作的E平均值，医生为3.69 μSv，第一助手为5.14 μSv，第二助手为3.69 μSv。医生手部的剂量为19.4 μSv，眼部晶状体的剂量为7.94 μSv。
介绍了乌拉圭测量ERCP辐射剂量的首批结果。这些操作会使患者和工作人员暴露于可测量的辐射剂量下，应考虑到这些剂量以将风险降至最低。
