Se destaca la alta incidencia de la malrotación como causa de oclusión duodenoyeyunal.Se analizan los dos mecanismos obstructivos: el vólvulo del intestino medio favorecido por la precaria fijación del mesenterio y la brida preduodenal descrita por Ladd. Se recuerda brevemente la embriología de los cambios de posición del asa umbilical y se esquematizanlas anomalías de estos cambios. Se hace una revisi¡n del cuadro clínico, destacando la preeminencia del vómito entre otros síntomas demenor relieve, así como sus características de forma de aparición, contenido, evolución y consecuencias. Se dan las pautas diagnósticas clínicas y paraclínicas, resaltando la importancia de la radiografía. Se hace referencia al tratamiento recomendando la táctica quirúrgica más aceptada, así como los cuidados más importantes del pre y postoperatorio. Finalmente, con el análisis de las causas de muerte, se estableée el pronóstico de la afección.
