Omphalocele synonyms

Omphalocele, also known as exomphalos, is a congenital abdominal wall defect where an infant's intestines or other abdominal organs protrude outside the belly through the umbilical cord. While the terms omphalocele and exomphalos are used interchangeably in clinical practice, omphalocele is the preferred terminology in modern medical literature and international classification systems.

What are the common synonyms for Omphalocele?

The condition is most frequently referred to as omphalocele, but patients may encounter several synonyms depending on the medical context or historical literature. The term "exomphalos" is the most common synonym, often used in European medical traditions. Historically, because the condition involves the umbilical cord, it has occasionally been described as a "fetal umbilical hernia," though this is medically imprecise. In clinical records, you may also see the abbreviation "OMP" used by healthcare providers.

Why are there multiple names for this condition?

The variety of names for omphalocele stems from historical efforts to categorize birth defects based on visual appearance rather than embryonic origin. Omphalocele (derived from the Greek omphalos, meaning navel, and kele, meaning tumor or hernia) became the standard as medical understanding of the condition's pathophysiology evolved. Reclassification efforts were necessary to distinguish omphalocele from gastroschisis, a different abdominal wall defect where the organs protrude through a hole in the abdominal wall rather than the umbilical cord.

How is Omphalocele classified in medical systems?

To ensure consistency in global healthcare, the following official classifications are used for omphalocele:

• ICD-10/11: Classified under congenital malformations of the abdominal wall (Q79.2).


• Orphanet: Listed under ORPHA:79333.


• OMIM: Documented under Entry #164750.
