Fortified milk: a rare cause of intestinal obstruction in pre-term patients. / Leche fortificada: una causa infrecuente de obstrucción intestinal en pacientes prematuros.

ABSTRACT

INTRODUCTION: Intestinal obstruction secondary to the use of fortified milk is a rare cause in pre-term patients. CASE REPORT We present the case of a female pre-term newborn admitted as a result of abdominal distension and rectal bleeding, which mimicked necrotizing enterocolitis. On abdominal X-ray, she had an obstruction pattern, and on ultrasonography, echogenic masses at the distal ileum were observed. Given the lack of improvement with conservative management, urgent exploratory laparotomy was decided upon. At surgery, compact milk masses at the level of the distal ileum were identified as the cause of intestinal obstruction. Appendicostomy and lavage with saline solution through the ileocecal valve were performed. This allowed milk masses to come out towards the colon, and a great amount of acholic stools to be expelled. CONCLUSION: The increase in "milk curd syndrome" cases should lead us to consider this cause in the differential diagnosis of intestinal obstruction in pre-term newborns fed with fortified milk.

RESUMEN

INTRODUCCION: La obstrucción intestinal secundaria al uso de leche fortificada es una causa infrecuente descrita en pacientes prematuros. CASO CLINICO Presentamos el caso de una recién nacida prematura que ingresa por distensión abdominal y rectorragia, simulando una enterocolitis necrotizante. En la radiografía abdominal presenta patrón obstructivo y en ecografía se identifican masas ecogénicas en íleon distal. Dada la no mejoría con manejo conservador, se decide laparotomía exploradora urgente. En la intervención se detectan masas compactas de leche a nivel de íleon distal como causa de la obstrucción intestinal. Se realiza apendicostomía y lavado con suero fisiológico a través de la válvula ileocecal, permitiendo salida de moldes hacia colon y expulsión de gran cantidad de heces acólicas. CONCLUSION: El repunte de casos de "milk curd syndrome" nos obliga a considerar esta causa en el diagnóstico diferencial de obstrucción intestinal en prematuros alimentados con leche fortificada.
