Duplicación de intestino delgado / Small bowel duplicity

RESUMEN

Las duplicaciones intestinales son malformaciones congénitas poco frecuentes. Pueden localizarse desde la boca al ano. En general son asintomáticas, aunque pueden complicarse y manifestarse como hemorragia digestiva o abdomen agudo en aquellos casos en que se localiza a nivel abdominal. Esto obliga a tenerlo en cuenta como diagnóstico diferencial ante estos cuadros. En adultos, el diagnóstico suele darse de manera casual en el acto operatorio. Si bien la conducta es quirúrgica, con resección de la duplicación, ya sea total o parcial, en casos asintomáticos no complicados, esta conducta es controversial. Se presentan tres casos asintomáticos no complicados, diagnosticados casualmente en operaciones abdominales por otras causas, en la que se optó por tratamiento conservador. Dos de los casos fueron operados en el Hospital Regional del Luque y el tercero en el Instituto Nacional del Cáncer. Se hace una revisión del tema.

ABSTRACT

Intestinal duplications are infrequent congenital malformations. They can be located since the mouth to the anus. Generally they are asymptomatic, although they can be complicated and manifest themselves as a gastrointestinal bleeding or an acute abdomen in those cases that they are located in an abdominal level. These cases compel us to think in them as a differential diagnosis. In adults, the diagnosis usually occurs by chance during the surgical procedure. Although the behavior is surgical, with a partial or total resection of the duplication, it is controversial in those asymptomatic or not complicated cases. It is presented three asymptomatic and not complicated cases which were diagnosed by chance during abdominal surgeries for other causes, and where we chose a conservative treatment. Two out of the three cases were operated in the Hospital Regional de Luque and the third case was operated in the Instituto Nacional del Cáncer. It is made a review of the subject.
