In recent decades studies have demonstrated that the ERCP is not an innocuous procedure. Its morbidity rate ranges between 5% and 19% 5,6,9 while diagnostic ERCP has a mortality rate ranging from 0.5% to 2% 5,6. This mortality rate is doubled in therapeutic ERCP 7, which obliges physicians not to use it diagnostically, but rather to use it therapeutically only when there is already a certain diagnosis. We must emphasize that the average age of the population studied was 54 years old, with ages ranging from 18 years old to 101 years old.
Estudios en las últimas décadas han demostrado que la CPRE no es un procedimiento inocuo, que alcanza una morbilidad entre el 5% al 19% 5, 6, 9 y en CPRE diagnostica una mortalidad entre el 0,5% y el 2% 5, 6; esta mortalidad se ve duplicada cuando se realiza una CPRE terapéutica 7, lo que obliga a ser usada como una herramienta terapéutica mas no diagnóstica, y requiere un diagnóstico acertado previo a la realización de la misma.
