INFANT COLONIC ATRESIA

1. COLONIC ATRESIA
NAME: JOHN FAREED

6. Babies born with colonic atresia may have other birth
defects, including
.Atresia in the small intestine
.Defects of the wall of the abdomen
.Hirschsprung disease
.Malrotation

7. Hirschsprung disease
• Hirschsprung disease is an intestinal disorder characterized by the
absence of nerves in parts of the intestine. This condition occurs
when the nerves in the intestine (enteric nerves) do not form
properly during development before birth (embryonic development).
This condition is usually identified in the first two months of life,
although less severe cases may be diagnosed later in childhood.

8. Causes of colonic atresia:
• Experts believe that colonic atresia are caused by an inadequate
supply of blood to baby's intestines during fetal development. They
appear to run in families, although a specific genetic cause has yet to
be discovered.

9. Signs and symptoms of colonic
atresia:
Colonic atresia may cause signs and symptoms due to intestinal
obstruction. Anyone with signs or symptoms of intestinal obstruction
needs medical help right away.
Signs of intestinal obstruction due to colonic atresia include
• bloating or visible swelling of the abdomen
• passing no stool
• vomiting, often with bile in the vomit, which makes it green in color
• These signs typically appear in babies soon after birth.

10. Diagonosis:
• To diagnose colonic atresia and stenosis, doctors ask about symptoms
and medical history and perform a physical exam and imaging tests.

11. Physical exam:
• During a physical exam, the doctor may
• check for bloating of the abdomen
• check for a lump or mass in the abdomen
• press or tap on the abdomen to check for tenderness or pain
• use a stethoscope to listen to sounds in the abdomen
• check for signs of complications, such as dehydration or infection

12. During a physical exam, the doctor may check for
bloating or a mass in the abdomen.

13. Imaging tests:
• Doctors may use the following tests to diagnose colonic atresia and
stenosis
• x-rays, which use a small amount of radiation to create pictures of the
inside of the body
• ultrasound, which uses sound waves to create an image of organs
• lower GI series, which uses x-rays and a chalky liquid called barium to
view the large intestine

14. Abdominal x-ray

16. Complications:
• Colonic atresia causes intestinal obstruction, in which the colon is
completely blocked. If colonic atresia is not diagnosed and treated
shortly after a baby is born, intestinal obstruction can lead to serious
complications such as:
• dehydration.
• a perforation, or hole, in the wall of the intestine.
• infection and sepsis, a serious illness that occurs when the body has
an overwhelming immune system response to an infection.
