It should be noted that, although our main objective was to study choledocholithiasis found during ERCP, we also looked at dilation of the bile duct when gallstones were not present. This topic was included because the bile duct could have become dilated as the result of a gall stone too small to be observed during performance of ERCP or because of a gallstone which had already migrated by the time ERCP was performed. This supports the opinion that when choledocholithiasis is suspected and a dilated bile duct is found without the presence of visible calculi, a papillotomy and bile duct exploration with basket should be preformed.
Cabe resaltar que si bien el objetivo principal del trabajo era comparar la coledocolitiasis en la CPRE, el parámetro de dilatación de la vía biliar sin cálculos también fue incluido porque la vía biliar se dilata posiblemente por la presencia de un cálculo, el cual por su tamaño pequeño no se observa al realizar la CPRE o ya ha migrado cuando se hace la misma; esto apoya el concepto de que cuando encontremos una vía biliar dilatada en la sospecha de coledocolitiasis, así no se vea el cálculo, debemos realizar papilotomía y exploración de la vía biliar con la canastilla.
