Thanks a lot!!!!umbilical hernia is midline muscle defect. Skin is ok. like other types of hernias.
gastchochisis is midline muscle and also skin defect, intestines are out on air, irritated matted, can easily perforate. and defect is always away from midline.
O is muscle, skin defect but covered with amniotic sac and umbilical cord protrudes thru it. you clearly see bowels in it, and portion of liver usually. if you dont rupture it kids may do totally fine. skin will grow over it by time with some betadine around skin daily. called "paint and wait" method. than it will turn in ventral hernia and you will treat it like usual muscle defect.
See the picture that's Omphalocele you will never forget it when seen once. there's liver saying hello through sac
Hope this helped.
