2009, Journal of Pediatric SurgeryCitation Excerpt :Mature motility of the gut has been reported around 36 weeks of gestation [16,17]. Almost 99% of all normal full-term infants pass meconium within 48 hours of birth [18,19]. Premature infants frequently present with delayed passage of meconium, 50% passing their first stool more than 2 days after birth and many not passing a stool until more than 1 week after birth.
Case 3-2012: A newborn boy with vomiting, diarrhea, and abdominal distention
2012, New England Journal of MedicineCitation Excerpt :Patients with Hirschsprung's disease, a congenital intestinal neuropathy characterized by the absence of ganglion cells extending from the rectum proximally for a variable distance, present with failure to pass meconium within 48 hours after birth and often progress to abdominal distention and vomiting.7 In healthy newborns, 94 to 99% pass meconium by 24 hours, and 100% by 48 hours.8,9 In newborns with Hirschsprung's disease, only 6% pass meconium by 24 hours,7 and 37 to 54% by 48 hours7,10 This patient first passed meconium at 30 hours of life, a finding consistent with Hirschsprung's disease.
