GU/GI disorders - exam 3 Flashcards
What is meconium
the dark green substance forming the first feces of a newborn infant.
what is Hirschsprung disease?
- congenital aganglionic (lack of ganglionic nerve cells) in part of the colon (leads to megacolon/mechanical obstruction d/t lack of peristalsis)
- usually involves rectum and distal colon
What are the signs and Sx of Hirschsprung disease?
- no meconium 24-48 hours after birth
- refusal to fee (FTT)
- vomiting, distention and constipation
- complications: enterocolitis (severe diarrhea, potentially fatal) and ribbon like stools, leads to dehydration
How do you Dx hirschsprung disease?
- x-ray after a barium enema
- rectal biopsy (can confirm 100%)
How to treat hirschsprung disease?
- “pull through” surgery
- temporary ostomy
- if total paralysis hirschsprung is present, ileostomy is needed
What is intussusception
- Telescoping (invagination) of 1 portion of intestine into another
- cause is usu unknown, may be d/t intestinal lesions
In what demographic is intussusception most common?
- in male infants (3-9 months)
- may happen up to 5 years old
What are the signs and Sx of intussusception?
- Colicky abdominal pain (intermittent in beginning, constant in later ischemic stage)
- bringing knees to belly
- acute pain
- edema, mucous, irritation, leaking of blood
- vomiting
- *RED CURRANT JELLY STOOLS (d/t mix of mucus and blood)
How is intussusception diagnosed?
by ultrasound guided saline enema
How is intussusception Treated?
- by air enemas (80% cases are able to be reduced by this non-operative route)
- if not, surgery is needed
What is pyloric stenosis?
- Hypertrophy of pylorus causing constriction of pyloric sphincter w obstruction of gastric outlet
- runs in families
When does pyloric stenosis usu develop?
-in first 2-5 weeks of life (more common in males)
What are the signs and Sx of pyloric stenosis?
- *PROJECTILE VOMITING
- child is hungry immediately after feedings
- poor weight gain or weight loss
- can result in signs of dehydration
- palpable olive shaped mass
How is pyloric stenosis diagnosed?
with sonogram (shows thickening of pylorus)
How is pyloric stenosis treated?
- treat dehydration
- surgical correction w fundoplacation (required!)
Post op considerations with pyloric stenosis surgery?
rapid recover feeding 4-5 hours post op
What is GERD
- Transfer of gastric contents into esophagus
- occurs in everyone but frequency and persistency is what makes is abnormal
In what pediatric demographic is GERD very common?
infants less than 2 months old (often resolves spontaneously)
What are the signs and Sx of GERD?
- regurgitation, vomiting, poor feeding, irritable, URI/wheezing
- Sandifer syndrome (arching of the back)
- heartburn
What is the treatment for GERD in peds?
- thicken formula w ith ceral
- feed small amts more often
- medications: H2 receptor antagonist (Zantac) or PPI (Nexium, Prevacid)
- surgical fundoplication
What is celiac disease?
- An autoimmune disease caused by sensitivity to the protein gluten
- if gluten is consumed (wheat, barley, rye) an immune response is triggered and damage is caused to lining of sm intestine
- once lining of sm intestines is damaged, nutrients cant be absorbed causing nutrient deficiencies
What are the signs and Sx of celiac disease?
- diarrhea, abdominal pain, ab distention, weight loss, fatigue
- frothy, foul-smelling stools
- malnutrition
- steatorrhea
- anemia
How is celiac disease treated?
with a gluten-free diet for LIFE
What are some grains/starches that are naturally gluten-free?
corn, quinoa, millet, rice, buckwheat, flax, lentils, potato, wild rice, soy, yucca, tapioca
