Objetivo: Avaliar as doses de exposição a radiação ionizante de pacientes
submetidos a procedimentos de CPRE.
Metodologia: Recolha de uma amostra de dados em duas instituições num total
de 267 pacientes, 198 numa instituição pública (A) e 69 numa instituição privada
(B).
Resultados: A mediana dos tempos de fluoroscopia é semelhante entre as duas
instituições em estudo, 4 minutos e 17 segundos na instituição A e 4 minutos e 21
segundos na instituição B, porém verifica-se uma diferença na mediana do DAP
com valores de 3,60 Gy.cm2 e 13,21 Gy.cm2. A dose efetiva mediana estimada foi,
respetivamente, de 0,94 mSv e 3,43 mSv.
Conclusão: As doses de exposição encontram-se dentro do intervalo de valores
praticados na literatura, sendo a avaliação do risco de desenvolvimento de cancro,
como consequência da exposição a procedimentos de CPRE, na Instituição A de
0,006% e na Instituição B de 0,025%.
Objective: Evaluation of exposure of patients to ionizing radiation in ERCP procedures using fluoroscopy. Metodology: Collection data at two institutions, 267 patients totaling, 198 in a public institution (A) and 69 in a private institution (B). Results: The median of fluoroscopy times is similar between the two institutions under the study, 4 minutes and 17 seconds at institution A and 4 minutes and 21 seconds at institution B, however there was a difference in the median of DAP with values of 3,60 Gy.cm2 and 13,21 Gy.cm2. The median of estimated effective dose was, respectively 0,94 mSv and 3,43 mSv. Conclusion: Exposure doses are within the range of values of the practiced literature, in which evaluation of the risk of developing cancer, due to exposure to ERCP procedures, is 0,006% at Institution A and 0,025% at Institution B.
