What causes bowel obstructions in babies and children?

Babies who have a bowel obstruction usually have some structural abnormality of the bowel. This means that during fetal development there was a problem so the bowel was not formed properly. Sometimes, when this happens, the problem is seen shortly after birth and sometimes things may seem normal for some time. 

If a malrotation has occurred - this is when the bowel turns that occur normally during fetal development have not occurred correctly - there may be no problem for years. If there is then a twisting of the bowel , this can cause a blockage - called a volvulus.
