Omphalomesenteric Duct Remnants

Abstract

Omphalomesenteric duct malformations are developmental defects relating to the closure of the omphalomesenteric duct. They are relatively rare diseases with a prevalence of around 2% of people. The malformations can take the form of a patent duct, a cyst, a fistula, or a sinus and may or may not be symptomatic. The usual treatment options are by surgical means. In this chapter, the underlying embryology, pathology, clinical presentation, and management of these malformations are discussed.
