Article information

La invaginación yeyuno-gástrica (IYG) retrógrada es infrecuentetras cirugía tipo Billroth II y excepcional sin antecedentes quirúrgicos.En la manera de presentación aguda, la menos infrecuente, es funda-mental un diagnóstico rápido y, en general, la corrección quirúrgicatemprana. Las formas habituales de establecer el diagnóstico son la ci-rugía, de urgencia en el contexto de abdomen agudo, o la endoscopia.Son escasas las descripciones de su aspecto con diferentes medios deimagen, y sólo hemos encontrado dos referencias en las que se hacemención a la ecografía como técnica capaz de alcanzar el diagnóstico.Presentamos el caso de un paciente con IYG retrógrada 36 años tras ci-rugía, en el que la ecografía permitió un diagnóstico rápido y sencillo.Se realiza una descripción pormenorizada de los hallazgos ecográficosy se discuten los aspectos epidemiológicos y clínicos de esta infre-cuente, pero no intrascendente entidad.

Retrograde gastrojejunal intussusception (GJI), an uncommon com-plication after Billroth II surgery, is exceptional in the absence of pre-vious surgery. In acute presentation, the least common type, rapiddiagnosis is fundamental, as generally is early surgical correction.Diagnosis is usually established by surgical intervention, under emer-gency conditions in the context of acute abdomen, or endoscopic exa-mination. There are few descriptions of the features shown by the dif-ferent imaging methods and we have found only two references inwhich ultrasound is described as a technique capable of establishingthe diagnosis. We present the case of a patient with retrograde GJI, de-tected 36 years after surgery, in which ultrasound led to a rapid andsimple diagnosis. The ultrasonographic findings are described in detailand the epidemiological and clinical aspects of this uncommon, butimportant, entity are discussed.
