Overview of Congenital Gastrointestinal Anomalies
Jejunoileal and Large Bowel Obstruction
(See also Meconium Ileus and Obstruction of the jejunum and ileum can occur as the result of Jejunoileal Atresia , In many cases, there is no history of maternal polyhydramnios because much of the swallowed amniotic fluid can be absorbed from the intestine proximal to the obstruction. Disorders that result in bowel obstruction, other than Malrotation of the Bowel , General diagnostic approach and preoperative management include the following: No oral food or liquid intake Nasogastric tube to prevent further bowel distention or possible aspiration of vomitus Correction of fluid and electrolyte disturbances Abdominal x-ray series In addition, a contrast enema may be helpful to delineate the anatomy and may also relieve the obstruction in neonates with meconium plug syndrome or meconium ileus. If Hirschsprung disease is suspected from the contrast enema, a confirmatory rectal biopsy is required. A biopsy is positive if it is devoid of intestinal ganglion cells (enteric neurons).
