Hirschsprung Disease synonyms

Hirschsprung disease is primarily known by its eponymous name, though it is historically and clinically referred to as congenital aganglionic megacolon. While medical records almost exclusively use the term Hirschsprung disease today, older literature or international classifications may occasionally utilize descriptive terms related to the condition's pathophysiology of nerve cell absence in the colon.

What are the alternative names for Hirschsprung disease?

In clinical practice, the most accurate and widely accepted term is Hirschsprung disease. Historically, the condition was referred to as congenital aganglionic megacolon, a name that describes the anatomical result of the disease—an enlarged colon (megacolon) caused by the lack of nerve cells (aganglionosis). Because the condition involves the absence of ganglion cells in the bowel, it is sometimes referred to in medical texts as aganglionic megacolon or congenital colonic aganglionosis. You may also see it abbreviated as HD or HSCR in medical charts and research papers.

Why does Hirschsprung disease have multiple names?

The variety of names stems from the historical evolution of medical diagnostics. The condition is named after Harald Hirschsprung, the Danish pediatrician who first described the clinical presentation in 1888. Before the underlying cause—the absence of enteric neurons—was fully understood, the condition was named based on its most visible symptom: the massive dilation of the colon. As our understanding of the enteric nervous system improved, "congenital aganglionic megacolon" became the preferred descriptive term to highlight the neurological origin rather than just the structural outcome. Today, "Hirschsprung disease" remains the standard nomenclature used by organizations like the NIH and the ICD-10/11 classification systems.

How is Hirschsprung disease classified in medical systems?

Standardized medical coding systems use specific identifiers to ensure consistency in research and patient care. Below are the primary ways Hirschsprung disease is categorized globally:

• ICD-10/11: Classified under congenital malformations of the digestive system (Q43.1).


• OMIM (Online Mendelian Inheritance in Man): Listed as #142623, emphasizing the genetic components of the disease.


• Orphanet: Recognized as ORPHA:408, providing a centralized reference for this rare condition.


• GARD (Genetic and Rare Diseases Information Center): Tracks the condition under the name Hirschsprung disease to assist families in finding verified resources.

Which name should patients and families use?

When communicating with your healthcare team, genetic counselors, or specialists, Hirschsprung disease is the universally recognized term. Using this name ensures that your medical team is aligned with current literature and diagnostic protocols. While you may encounter the term "congenital aganglionic megacolon" in older medical journals or archives, it is rarely used in modern clinical settings.
