Notes on Pediatric GI Disorders

Tracheoesophageal Fistula (TEF): Congenital condition where the trachea and esophagus are improperly formed.
Types of TEF:
1. Type A: No tracheoesophageal fistula, only esophageal atresia (8% of cases). The esophagus divides into two parts, leading to blind pouches.
2. Type B: Rare, affects about 2% of cases. The lower part of the esophagus ends in a blind pouch.
3. Type C: Most common form (85% of cases). The upper esophagus ends in a blind pouch, while the lower portion is connected to the trachea by a fistula.
4. Type D: Very rare form.
5. Type E: Atypical; the tracheoesophageal fistula connects to both the esophagus and the trachea (4% of cases).

Polyhydramnios: Increased amniotic fluid during pregnancy due to the inability of the fetus to swallow.
At Birth:
- Vomiting and choking during the first feeding.
- Drooling, related to atresia (blockage).
- If the upper esophagus enters the trachea, it leads to choking and cyanosis.
- If the lower end presents trachea connection, they have abdominal distension due to air entering the stomach.
Management Goals: Prevent pneumonia and apnea, careful feeding assessments, avoid the risk of aspiration.

Feeding Strategy: Administer clear fluids and colostrum to minimize aspiration risks.
Surgical Repair: Essential for survival; surgical correction of the anatomic defect.

Definition: Abnormal thickening of the pyloric muscle, leading to gastric outlet obstruction.
Prevalence: More common in boys.
Symptoms:
- Projectile vomiting, often green in color (similar to the movie "The Exorcist").
- Vomitus includes mucus and milk remnants.
- Infants may appear hungry shortly after vomiting due to loss of fluids.
- Olive-shaped mass felt in the upper right quadrant of the abdomen.

Pyloriomyotomy: Surgical intervention required.
Preoperative Care:
- Administer IV fluids to prevent dehydration.
- Transition to thickened liquids via teaspoon or nipple with a large hole to mitigate aspiration risk.
- Position infants post-feed to facilitate stomach drainage into intestines.
- Monitor surgical site for signs of infection, maintain hygiene.

Definition: An autoimmune disorder triggered by gluten ingestion in genetically predisposed individuals.
Age of Onset: Typically manifests between 6 months to 2 years when gluten-containing foods are introduced.
Symptoms:
- Abdominal distension, atrophy of buttocks, failure to thrive, large and frothy stools.
Diagnosis: Serum IgA tests to confirm malabsorption; stools test for characteristics.

Definition: Aganglionic megacolon; lack of proper intestinal nerve cell development, leading to constipation and obstructive symptoms.
Symptoms: Ribbon-like stools, abdominal distension, vomiting, anorexia, failure to thrive.
Diagnosis: Barium enema and rectal biopsy.
Treatment: Surgical removal of the affected bowel section.

Definition: A condition where one segment of the intestine telescopes into another, causing obstruction.
Symptoms: Severe pain, irritability, possible vomiting of currant jelly-like stools due to mixing of blood.
Treatment: Barium enema for diagnosis and potential treatment, or surgical correction if necessary.

Definition: Inflammation of the stomach and intestines.
Management Goals: Identify cause, restore fluids and electrolytes. Use oral rehydration solutions like Pedialyte.
Preventive Education: Promote hand hygiene and safe food handling.

Characteristics: Similar to adults, manifests differently in infants due to inability to articulate discomfort.
Management: Ensure proper feeding posture, consider medications to manage reflux, and provide gentle burping to minimize discomfort.

Cleft Lip: Congenital defect during fetal development leading to an opening that can vary in severity. Surgical repair typically needed.
Cleft Palate: Involves the roof of the mouth not fully closing; requires surgical intervention for proper feeding and speech development.
Postoperative Care: Prevent sucking or straining; maintain hygiene of the repair site, promote comfort and emotional support for infants.
