Which clinical manifestation is indicative of gastroschisis?

The clinical manifestation indicative of gastroschisis involves the appearance of the bowel, which typically appears edematous and matted when exposed. In gastroschisis, the bowel protrudes outside the abdominal cavity through a direct defect in the abdominal wall, usually to the right of the umbilicus. Unlike other conditions, such as omphalocele, the bowel in gastroschisis is not covered by a membrane, making it unprotected and more susceptible to damage and inflammation.

In the case of gastroschisis, the exposed bowel often becomes edematous due to compromised blood supply and environmental exposure, leading to a thickened appearance. The matting refers to the adherence of the bowel loops to one another due to edema and inflammation, rather than being free and mobile. This contrasts with conditions where a protective membrane is present or where the bowel is intact.

The other manifestations included in the options relate to different clinical presentations, either associated with omphalocele or other gastrointestinal issues. For instance, a presence of a membrane typically suggests an omphalocele rather than gastroschisis. Non-bilious vomiting can occur in various gastrointestinal obstructions, but does not specifically indicate gastroschisis, which is characterized by more
