Intestinal Atresia, Stenosi And Malrotation Flashcards
Most common intestinal atresia occurs in……..
More than 90% of intestinal stenosis and atresia occurs in the duodenum, jejunum, and ileum.
What happens to bowel in gut Malrotation…..
Malrotation is associated with inadequate mesenteric attachment of the intestine to the posterior abdominal wall, which leaves the bowel vulnerable to auto obstruction as a result of intestinal twisting or volvulus
Classic symptoms of obstruction in the neonate
Include vomiting, abdominal distention, and obstipation
Clues for high intestinal obstruction….
The presence of polyhydramnios should prompt aspiration of the infant’s stomach immediately after birth.
Aspiration of more than 15-20 mL of fluid, particularly if it is bile stained, is highly indicative of proximal intestinal obstruction.
In the postnatal period, a……….. is the initial diagnostic study
plain radiograph
X-ray features in obstruction…..
Plain radiographs reveal bowel distention proximal to the point of obstruction
Initial treatment of infants and children with bowel obstruction must be directed at…
fluid resuscitation and stabilizing the patient
The hallmark of duodenal obstruction……
Bilious vomiting without abdominal distention, which is usually noted on the first day of life
Plain abdominal radiograph findings in duodenal obstruction…….
Presence of a double-bubble sign.
Double bubble sign……,,,
The appearance is caused by a distended and gas-filled stomach and proximal duodenum, which are invariably connected
The typical surgical repair for duodenal atresia is…
Duodenoduodenostomy
The primary etiologies of congenital small bowel obstruction involve
intrinsic abnormalities in anatomic development (jejunoileal stenosis and atresia),
mucus secretion (meconium ileus), and
bowel wall innervation (long-segment Hirschsprung disease).
Meconium ileus occurs primarily in newborn infants with…….
Cystic f ibrosis, an exocrine gland defect of chloride transport that results in abnormally viscous secretions
