Rigler's triad
Tríada de Rigler
Resumen:
68-year-old patient, with no surgical history.He was admitted to the Emergency Department with a clinical picture of intestinal occlusion. A simple abdominal radiograph was requested (only obtained in decubitus), observing the presence of Rigler's radiological triad, pathognomonic of the biliary ileum. The 3 elements are indicated: dilated thin handles (black arrow), aerobilia (white arrow) and the ectopic calcified stone in the right iliac fossa (yellow arrow). Gallstone ileus is intestinal occlusion as a consequence of the migration of a gallstone through a bilio-digestive fistula and its impaction, frequently at the level of the ileo-cecal valve. Usually it is a cholecysto-duodenal fistula, although it can also be a cholecysto-colonic fistula. The classically described clinical picture is that of intermittent occlusion, being more frequent in elderly patients, with a long history of symptomatic biliary lithiasis.
Paciente de 68 años, sin antecedentes quirúrgicos. Ingresó a Emergencia con cuadro clínico de oclusión intestinal. Se solicitó radiografía simple de abdomen (solamente se obtuvo en decúbito), observándose la presencia de la tríada radiológica de Rigler, patognomónica del ileo biliar. Se señalan los 3 elementos: asas de delgado dilatadas (flecha negra), aerobilia (flecha blanca) y el cálculo calcificado ectópico en la fosa ilíaca derecha (flecha amarilla). El íleo biliar es la oclusión intestinal como consecuencia de la migración de un cálculo biliar a través de una fístula bilio-digestiva y su impactación, frecuentemente a nivel de la válvula ileo-cecal. Habitualmente se trata de una fístula colecisto-duodenal, aunque también puede tratarse de una fístula colecisto-colónica. El cuadro clínico clásicamente descrito es el de una oclusión intermitente, siendo más frecuente en pacientes añosos, con larga historia de litiasis biliar sintomática.
