Hirschsprung’s Disease

Hirschsprung's Disease is a congenital developmental disorder characterized by the absence of ganglion cells (aganglionosis) in the distal bowel, extending proximally from the anus for a variable distance. This results in a functional bowel obstruction due to the failure of the affected segment to relax.

The disease is caused by the premature arrest of craniocaudal migration of neural crest cells (the precursors of enteric ganglion cells) between the 5th and 12th weeks of gestation. It has a complex, multigenic etiology. Mutations in the RET proto-oncogene are identified in approximately 50% of familial and 15% of sporadic cases. Other implicated genes include EDNRB, EDN3, GDNF, and SOX10.

The absence of the myenteric (Auerbach’s) and submucosal (Meissner’s) plexuses leads to a lack of coordinated peristalsis. The aganglionic segment remains in a state of tonic contraction due to unopposed cholinergic stimulation and lack of nitric oxide-mediated relaxation. This creates a functional obstruction, causing progressive dilation and hypertrophy of the proximal, normally ganglionated colon (megacolon).

• Prevalence: Approximately 1 in 5,000 live births.
• Gender: Strong male predominance, with a male-to-female ratio of 4:1 in short-segment disease.
• Age: Usually diagnosed in the neonatal period, though ultra-short segment cases may present in late childhood or adulthood.

• Male sex
• Family history of Hirschsprung's disease
• Associated genetic syndromes (e.g., Down syndrome/Trisomy 21 in 10% of cases, Mowat-Wilson syndrome, Waardenburg syndrome type 4, Congenital Central Hypoventilation Syndrome)

• Inspection: Marked abdominal distention; visible peristalsis in thin children.
• Palpation: Palpable fecal masses throughout the abdomen.
• Auscultation: Hyperactive or high-pitched bowel sounds during acute obstruction.
• Digital Rectal Exam (DRE): A snug, hypertonic anal sphincter and an empty rectal vault. Withdrawal of the finger often results in a sudden, forceful release of gas and liquid stool (the "blast sign" or "squirt sign").

• A. Clinical Assessment: Medical history highlighting delayed meconium passage and severe, early-onset constipation.
• B. Laboratory Testing: Baseline blood counts and electrolytes; evaluation for sepsis if enterocolitis is suspected.
• C. Imaging Studies: Contrast enema and abdominal radiographs.
• D. Functional Tests: Anorectal manometry.
• E. Biopsy Findings: Rectal suction biopsy (Gold Standard).

• G. Differential Diagnosis: Differentiating from functional constipation and other causes of neonatal bowel obstruction.

• Functional Constipation: Onset is typically after infancy; encopresis is common; rectal biopsy is normal.
• Meconium Ileus (Cystic Fibrosis): Microcolon on contrast enema; sweat chloride test is diagnostic.
• Anorectal Malformations (e.g., Anal Stenosis): Diagnosed on physical examination.
• Hypothyroidism: Screened via thyroid-stimulating hormone (TSH) levels; associated with systemic hypotonia.

• Hirschsprung-Associated Enterocolitis (HAEC): The leading cause of mortality.
• Bowel Perforation: Secondary to extreme megacolon.
• Anastomotic Stricture or Leak: Post-surgical complications.
• Fecal Incontinence or Severe Constipation.

Most infants undergo successful pull-through surgery and achieve good bowel control. Long-term survival is excellent (>95%). However, up to 30% of patients experience persistent post-operative issues, including fecal incontinence, chronic constipation, or recurrent enterocolitis, which usually improve with age.

There are no primary preventive measures. Genetic counseling is recommended for families with a history of Hirschsprung's disease to assess recurrence risk in subsequent pregnancies.
