Types of intestinal obstructions are found by using the technique of prenatal jejunoipeal. This ultrasound imaging technique indicates the level of amniotic fluid. If jejunoilewl is an excess of amniotic fluid found in ultrasound, then there is a chance of intestinal atresia. An intestinal failure of absorbing amniotic fluid results in excess of this fluid and is found by the ultrasound imaging technique.

If a new born is under suspect of intestinal obstruction or intestinal atresia, then the new born must go through the following diagnostic processes:. Surgery is performed in most of the cases of jejunoileal atresia, but it depends upon the types of the intestinal atresia. The operations are mostly focused on removal of the intestinal blind end sections. The remaining ends are then joined or sutured. The surgery is performed in the warmed room or operating room with proper care under general anaesthesia.
