Abstract
|
|
|
In the early human embryo, alimentery canal communicates freely with the Yolk Sac.
This canal is known as the omphalomesenteric duct and is referred to as the vitellointestinal duct. As development proceeds, the duct becomes narrow and lies within the umbilical cord under normal
conditions, the duct disappears and the intestine has no connection with the yolk sac.
Under abnormal conditions, all or any part of the duct may persist and resulting in various anom
alies. A case of patent omphalomesenteric duct, complicated by prolapse of the intestinal mucosa through the umbilicus, was experienced at the surgical department of Korea University Medical College.
