What characterizes the membrane covering the viscera in omphalocele?

The characteristic membrane covering the viscera in omphalocele is indeed thin and transparent. In omphalocele, the abdominal contents, commonly including the intestines and, in some cases, other organs, herniate through a defect in the abdominal wall, typically at the umbilical site. These organs remain enclosed in a translucent membrane, which is composed of peritoneum, amnion, and Wharton's jelly.

This thin and transparent membrane allows for some visibility of the internal organs, providing a unique presentation that differs from other abdominal wall defects, where either the organs are exposed directly to the environment or are covered by a thicker layer. The presence of this membrane is significant for several reasons, including its role in protecting the contents and facilitating surgical repair. Recognizing these characteristics is crucial for neonatal care and management of infants with this condition.
