RESUMEN
La enfermedad por reflujo gastroesofágico resistente se define como la persistencia
de pirosis posterior a ocho semanas de tratamiento óptimo con inhibidor de la bomba
de protones, dos de sus causas principales son la pirosis funcional e hipersensibilidad
al reflujo definidas de acuerdo con los criterios de Roma IV como síntomas típicos
de pirosis en presencia de estudios normales de: endoscopia superior (incluyendo
biopsias), pH metría-impedancia y manometría de alta resolución. La pirosis funcional
tiene asociación negativa entre los síntomas y eventos de reflujo, mientras
que en la hipersensibilidad al reflujo esta asociación es positiva. Representan más
de 90% de los pacientes con pirosis en los que falló el tratamiento con inhibidor
de la bomba de protones a doble dosis, afectan principalmente a mujeres jóvenes
de mediana edad, comúnmente se sobreponen a otros trastornos gastrointestinales
funcionales y se asocian con algún tipo de comorbilidad psicológica. Su tratamiento
es con neuromodulares, como antidepresivos tricíclicos e inhibidores selectivos
de la recaptura de serotonina, entre otros. La cirugía antirreflujo tal vez juegue un
papel importante en el tratamiento de la hipersensibilidad al reflujo, no así en la
pirosis funcional.
