What's the approx. time for the presentation of Intussusception, Pyloric stenosis and Hirschsprung's disease. I came across a lot of questions that talk about intestinal obstruction in newborn that don't give you the obvious hints (eg: projectile vomiting for pyloric stenosis) but just give you when the symptoms started in hours or days and then they will give you all 3 or 2 of these diseases in the options.
Pyloric stenosis occurs between 2-8 weeks. Any vomiting before 2 weeks is not Pyloric stenosis ( might be duodenal atresia)..
The peak incidence of Intussusception between 5-10 months of age..( colicky pain and vomiting .. Milk then bile!!.and red currant jelly stool
Hirschsprungs.. I dont know exactly but its typically occurs in neonate period with delayed meconium passage, bilious vomiting..( sigmoid commonest)..))
Meconium ileus: imediately after birth,abd:distension + billious vomiting Duodenal atresia: few hours after birth,bilious vomiting without abd:distension,double buble sign jejunoileal atresia: within 24hrs after birth,abd: distension +vomiting+ air fluid levels on abd: film malrotation with volvulus: at 3 to 7 days + bilious vomiting + rapid deterioration with volvulus + spiral sign on uper GI U/S + abnormal location of Superior mesentric vesels Necrotizing ileus: 10-12 days after birth +bloody stools + abd:distension + bilious vomiting Hirschsprung disease: upto 90% of infants unable to pas meconium within 24hrs after birth (normaly they pas b/w 24hrs) + bilious vomiting + poor feeding + progresive bowel distension + dificuilt bowel movements (age varies, in 80% cases symptoms apears within 1st 6weeks of life, and in 90% cases: neonates unable to pas meconium within 24hrs its diagnosed at that time) Pyloric stenosis: vomiting after every feeding (projectile non bilious vomiting) starts between 3 weeks-5months of age Intussusception:6months-3years of age, triad of s/s : abdominal pain + vomiting + pasage of blood per rectum..
