Minimizing radiation exposure in endoscopic retrograde cholangiopancreatography: a review for medical personnel

Fluoroscopy is used frequently during endoscopic procedures, such as endoscopic retrograde cholangiopancreatography (ERCP). However, exposure to radiation is an important health concern, primarily because of the potential increase in the lifetime risk of malignancy. This consideration is important for patients and staff exposed to radiation during ERCP. Thus, an understanding of how radiation doses are measured during ERCP and the potential risks of this radiation is important. Additionally, staff must be educated about methods used to minimize the radiation dose, such as the use of different imaging techniques, the general principles of fluoroscopy, and advances in hardware and software. The use of personal protective equipment is also essential to minimize occupational exposure. However, no comprehensive ERCP guideline on the use of X-ray systems in clinical settings or on radiation protection for operators has been established. This review focuses on the properties of fluoroscopy systems and methods of radiation protection for physicians and assistants participating in ERCP.
