El esfínter esofágico inferior, una banda de fibras musculares, cierra el esófago del estomago. Si el esfínter no se cierra de manera apropiada, el alimento puede devolverse hacia el esófago y causar acidez y otros síntomas conocidos como enfermedad gastroesofágica (GERD). Para aliviar los síntomas, se prescriben medicamentos y cambios en la dieta y para un paciente que experimente síntoma persistentes a pesar del tratamiento médico, una operación anti-reflujo puede ser una opción.
