midgut malrotation in older children

midgut malrotation is typically presented during the first few months of life but sometimes may encounter later in life, causing difficulties and mistakes in diagnosis. we reviewed records of eleven rare patients with midgut malrotation older than one year of age and extracted their clinical and paraclinical data. the most common presenting symptoms were bilious vomiting, recurrent abdominal pain and constipation. five of eleven patients had presented from neonatal period. the average interval between first symptoms and surgical correction of malrotation was about 22 months. some of the patients had been undergone false treatments. most cases were diagnosed by contrast studies (upper gastrointestinal series and barium enema). diagnosing midgut malrotation in older children is often delayed. this anomaly should be suspected in all children with signs and symptoms of small bowel obstruction, chronic abdominal pain and vague abdominal discomfort and in all patients of any age with abdominal discomfort who do not respond to other therapies. contrast studies may be necessary to rule out malrotation in suspected patients.
