ABSTRACT
Intussusception can be seen as a rare cause of bowel obstruction in adults. The diagnosis of intussusception utilises several imaging modalities; however, it differs slightly for paediatric and adult cases. The aim of an air enema is to identify the site of the abnormality and to force the intussusceptum into its normal position. Intussusception is a life-threatening condition due to the risk of bowel ischaemia and perforation, and so prompt diagnosis is necessary. Bowel malrotation is considered a surgical emergency owing to the high risk of bowel ischaemia. Meconium ileus is a common cause of bowel obstruction in the neonate; its presence usually indicates an underlying diagnosis of cystic fibrosis. Abnormalities of the duodenum are among the commonest causes for proximal small bowel obstruction in neonates. There is a spectrum of abnormalities ranging from complete duodenal atresia to duodenal stenosis/webs, as well as extraduodenal abnormalities resulting in obstructions such as haematoma, annular pancreas and superior mesenteric artery syndrome.
