Umbilical Hernia

 Can cause patient symptoms but does not necessitate urgent surgery



• Findings of bowel ischemia include evidence of bowel obstruction, bowel wall thickening, fat stranding, etc.




TOP DIFFERENTIAL DIAGNOSES




• Omphalocele
image Congenital defect in abdominal wall at umbilicus

image May allow some or nearly all abdominal contents to herniate

• Ventral hernia
image Epigastric and hypogastric hernias develop above and below umbilicus, respectively

image Incisional hernias develop through prior incision site

• Spigelian hernia
image Between linea semilunaris and lateral rectus abdominis

image Often has intact external oblique muscle or aponeurosis


PATHOLOGY




• Congenital: Due to incomplete closure of umbilical ring
image More likely in children with Down syndrome, trisomy 18, mucopolysaccharidoses, Ehlers-Danlos syndrome, and Beckwith-Wiedemann syndrome

• Acquired: Results from weakening of cicatricial tissue that normally closes umbilical ring
image Usually secondary to ↑ intraabdominal pressure (e.g., obesity, multiple pregnancies, tense ascites, etc.)
