[Non-obstructive enterolithiasis: report of two cases]. / Enterolitiasis no obstructiva: presentación de 2 casos.

Enterolithiasis, or coprolithiasis, stones formed mainly in the intestine, is uncommon in humans and is generally associated with intestinal stasis. This entity is highly common in some animals, such as horses. Enterolithiasis is usually asymptomatic but may lead to intestinal occlusion and should be considered as a possible cause of this event. We report two cases of enterolithiasis, in which the diagnosis was established by simple abdominal radiography and computed tomography. Although both patients had factors favoring the development of enterolithiasis, a genetic substrate predisposing them to this uncommon clinical entity cannot be excluded.

Enterolitiasis no obstructiva: presentación de 2 casos / Non-obstructive enterolithiasis: Report of two cases

La enterolitiasis o coprolitiasis, cálculos formados primariamente en el intestino, es una rara enfermedad en humanos asociada, generalmente, con estasis intestinal. Es sin embargo muy frecuente en algunos animales como los caballos. Suele cursar sin síntomas en la mayoría de los casos, pero puede presentar oclusión intestinal y debe ser tenida en cuenta como posible causa de la misma. Presentamos 2 casos de enterolitiasis cuyo diagnóstico fue establecido por imágenes de radiografía simple de abdomen y tomografia computarizada (TC). Aunque ambos pacientes presentaban factores favorecedores para enterolitiasis, no se puede descartar un sustrato genético que predisponga al desarrollo de esta infrecuente entidad clínica (AU)
