ABSTRACT

Introduction: Radiation levels dissipated by radiological procedures, such as the endoscopic retrograde Cholangiopancreatography (ERCP) affect both, the patient as to the medical staff. Regulatory conditions and radiological magnitudes are the basis for carrying out the present evaluation.
Materials and methods: Fluoroscopy equipment was used operated in automatic mode and, for measuring the radiological magnitudes, double emulsion film dosimeter was used. Staff evaluated was classified as gastroenterologist endoscopist (G1), assistant (A1), instrumentalist (A2) and patient (P).
Results: A total of seven patients (six female patients and one male patient) were studied whose age range was among the 25 to 79 years old. Three projections were obtained (thorax, pelvis and kidneys) for patient and (thorax, cervical spine and gonads) for medical staff.
Discussion: Orienting levels values observed with dosimeters went smaller to those established in RGSR compared to radiation doses. However, equipment used for intervention ERCP does not comply with national standard regulatory values, in spite of the fact that through conventional mode, it complies.
Conclusion: Regulations established by the corresponding authority in the use of the X Rays-emitting equipment is necessary for the benefit of both, medical staff and of the patients.
