Fortified milk: a rare cause of intestinal obstruction in pre-term patients.

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.
