Tránsito esofagogastroduodenal - Risks

Nombres alternativos

Tránsito gastrointestinal; Esofagografía; Tránsito gastroduodenal

Cuáles son los riesgos:

Hay una baja exposición a la radiación, lo cual ofrece un riesgo muy pequeño de cáncer. Los rayos X se vigilan y regulan para suministrar la cantidad mínima de exposición a la radiación que se necesita para producir la imagen. La mayoría de los expertos cree que el riesgo es bajo comparado con los beneficios.

Las mujeres embarazadas generalmente no deben someterse a este examen. Los niños son más sensibles a los riesgos de la exposición a los rayos X.

El bario puede causar estreñimiento. Consulte con el médico si éste no ha salido a través del aparato digestivo en 2 ó 3 días después del examen.

Consideraciones especiales:

El estudio del tránsito esofagogastroduodenal debe realizarse después de otros procedimientos radiológicos, dado que el bario que permanece en el cuerpo puede bloquear detalles en otros exámenes imagenológicos.
