Abdominal wall and umbilical disorders
Also known as Gastroschisis · Exomphalos · Omphalocele · Umbilical hernia · Inguinal hernia · Umbilical granuloma · Omphalitis · Patent processus vaginalis · Giant omphalocele · Epigastric hernia
Fellowship guide to abdominal wall and umbilical disorders in children, built around the rule that gastroschisis sits to the right of a normally inserted cord with bare bowel and no sac, while an omphalocele sits in the midline with its contents covered by a sac and carries chromosomal and cardiac associations. The page covers the embryology of the two wall defects, the surgical versus expectant management of umbilical and inguinal herniae, the salt or silver nitrate treatment of the umbilical granuloma, and the red flag of omphalitis progressing to necrotising fasciitis.

Red flags
- Gastroschisis has bare bowel to the right of a normally inserted cord with no covering sac, and it is rarely associated with chromosomal anomalies, which is the reverse of omphalocele
- A giant omphalocele containing liver, or any omphalocele, mandates chromosomal and cardiac assessment before surgical planning because associated anomalies drive prognosis
- An inguinal hernia never closes spontaneously and carries its highest incarceration risk in the first year of life, so it needs prompt elective repair rather than watchful waiting
- An incarcerated inguinal hernia that is tender, firm and irreducible with signs of obstruction or strangulation needs urgent surgical exploration, not prolonged reduction attempts
- Omphalitis with surrounding cellulitis, purulent discharge or systemic signs in a neonate is a surgical emergency because it can progress to necrotising fasciitis within hours

Overview & Definition
Picture a newborn delivered at a tertiary obstetric unit whose intestines lie exposed beside the umbilical cord, or an infant in clinic whose mother points to a soft bulge at the belly button that pops in and out. These two children anchor the two ends of abdominal wall and umbilical disease in paediatrics. At one end sit the congenital wall defects, gastroschisis and omphalocele, which are life-threatening surgical emergencies recognised at birth or before. At the other end sit the common herniae and minor umbilical conditions that a general paediatrician manages every week. [3] [4]
The single discriminating fact to hold above all others is the relationship between the defect, the sac and the cord. In gastroschisis the bowel herniates through a full-thickness defect to the right of a normally inserted cord and lies uncovered. In an omphalocele, or exomphalos, the midline defect sits at the umbilicus, the contents are wrapped in a translucent sac, and the cord inserts onto that sac. This one anatomical difference predicts the chromosomal and cardiac associations, the urgency and the prognosis. [1] [3]
The governing principle is therefore to classify the defect first by its anatomy, then to apply the correct urgency. A congenital wall defect at birth needs protection of the bowel, vascular access and immediate transfer to a neonatal surgical centre. An umbilical hernia in a thriving toddler needs reassurance and a plan to observe. An inguinal hernia in any infant needs a prompt surgical referral because it will not close on its own and can incarcerate. Matching the anatomical diagnosis to the right timeline of action is the whole skill. [4] [7]
