Background: If a newborn does not pass the first bowel movement within 48 hours, there may be an underlying cause. We describe a rare cause of delayed meconium passage.
Case Description: The neonate was born after a gestational age of 40 weeks and 2 days. The home birth was followed by a good start. Radiological imaging was performed due to the absence of the first stool and an increase in abdominal distention. The imaging showed an abnormal course of the colon with an sudden stop. Subsequently, surgery was conducted and an intestinal malrotation with a colonic atresia was found. During the surgery, a colonic anastomosis with a deviating loop ileostomy were constructed. The postoperative course was uneventful.
Conclusion: Delayed meconium passage has a very extensive differential diagnosis, in which an atresia of the intestine is one of the possibilities. A quick and structured approach is essential to prevent a possible blow-out of the intestine.

Introduction: The cut-off for referral to a higher center and further investigations for the delayed passage of first urine and meconium by a neonate have been traditionally kept after 48 hours of birth. There are very few studies regarding this in Indian neonates, and previous studies have relied primarily on the mother's recall of the event which may have led to recall bias. Therefore, through this study, we wanted to use hospital intake/output records to identify the risk factors that affect the timing of passage of first urine and stool in neonates delivered at our center and to find out if the cut-off of 48 hours to call it a delay is justifiable.

Meckel-Gruber syndrome (MGS) is a rare disease with a fatal, autosomal recessive inheritance pattern. This article mentions the neonatal MGS case followed by intestinal atresia and meconium pseudocyst clinic. Bile-containing-fluid was aspirated from the fetus, which was found to have polyhydramnios, gastric dilatation, lung hypoplasia, and cystic formation with a diameter of 68*62mm in the abdomen at 32 weeks of gestation in the intrauterine period.

Meconium, a non-invasive biomaterial reflecting prenatal substance accumulation, could provide valuable insights into neonatal health. However, the comprehensive protein profile of meconium across gestational ages remains unclear. Here, we conducted an extensive proteomic analysis of first meconium from 259 newborns across varied gestational ages to delineate protein composition and elucidate its relevance to neonatal diseases.

Introduction: Various approaches are employed to expedite the passage of meconium in preterm infants within the neonatal intensive care unit (NICU), with glycerine enemas being the most frequently used. Due to the potential risk of high osmolality-induced harm to the intestinal mucosa, diluted glycerine enema solutions are commonly used in clinical practice. The challenge lies in the current lack of knowledge regarding the safest and most effective concentration of glycerine enema.

Hirschsprung's disease (HD) is characterized by a congenital absence of enteric ganglion cells in the intestine, posing challenges in diagnosis, particularly in pediatric patients. The gold standard, rectal suction biopsy (RSB), carries risks, prompting an exploration of non-invasive alternatives such as high-resolution anorectal manometry (HR-ARM) for HD screening. We conducted a retrospective analysis of 136 patients suspected of HD between 2018 and 2022, which were stratified into three age groups: ≤12 months, ≤24 months, and >24 months.
