In my opinion it is important to mention that the use of the 30% level of direct bilirubin as an indicator had not been published previously, although these levels are expected in patients suspected of obstructive jaundice. It would have been interesting to know how well bilirubin levels in ranges between 2.8mg/dl and 4 mg/dl and at levels greater than 4 mg/dl predicted choledocholithiasis since according to the ASGE guidelines the first is a B predictor and the second is a very B predictor.
En mi opinión, es importante mencionar que el porcentaje de 30% de bilirrubina directa previamente no se había publicado aunque es lo esperado en un cuadro de ictericia obstructiva; hubiese sido interesante conocer cómo se comportaron las variables del nivel de bilirrubinas para los rangos de 2,8-4 mg/dl y superiores a 4 mg/dl que, de acuerdo a las guías del ASGE, son considerados como predictores fuerte y muy fuerte respectivamente.
