how does pyloric stenosis present
2-12 wks of age, regurgitation, nonbilious vomiting, hungry, dehydrated, oliguria, electrolyte imbalance, apathy, constipation
what are some exam findings of pyloric stensis
post-prandial distension, visible peristaltic wave, olive-like mass in RUQ
what are some imaging findings with pyloric stenosis
string sign
how is pyloric stenosis treated
hydration, electrolyte, laparoscopic pyloromyotomy
what is intussusception
telescoping segment of bowel into adjacent more distal segment (most common terminal ileum into R colon)
what is the most common cause of intestinal obstruction and abdominal emergency in 1st 2 yrs of life
intussusception, M:F 3:2
what are the potential eti of intussusception
75% idiopathic, viral enteritis, lead lesion (Meckel diverticulum, polyps, vascular abnormality, FB), celiac, CF, intestinal lymphoma >6yr, post op
what are some exam findings of pyloric stensis
post-prandial distension, visible peristaltic wave, OLIVE-LIKE mass in RUQ
what are some imaging findings with pyloric stenosis
STRING sign
how does intussusception present
healthy child sudden onset, severe pain, cyclical 1-15min, V/D , “CURRANT JELLY” stool w/in 12hr, withdrawn, pallor, sweat
what are some exam findings with intussusception
TTP, +/- distention, SAUSAGE-SHAPED mass usually Rmid/RUQ

saline/contrast/air enema, sx-reduce/resect necrotic
what is meconium ileus
bowel obstruction from thickened meconium- usually terminal ileum
