Scaphoid abdomen Increased chest wall diameter Bowel sounds may be heard in the chest with decreased breath sound. Cardiac impulse is displaced away from the side of hernia. 2)   After neonatal period Vomiting as a result of intestinal obstruction Mild respiratory symptoms Occasionally, incarceration of the intestine will proceed to ischemia with sepsis and shock.
