It is common to confuse umbilical bulge with umbilical hernia. A case of this deformity may be encountered in about 3000-4000 deliveries (including cesarean section): in the central part of the abdomen of the newborn, corresponding to the umbilical cord, there are abdominal organs protruding from the abdomen, covered with a transparent capsule through which the internal organs can be seen. There are umbilical cord stumps attached to the capsule, especially the umbilical arteries and veins, which are particularly prominent. Sometimes, part of the stomach, liver and spleen may also be displaced within the sac. It may also have other congenital malformations, such as small bowel atresia, anal atresia, bladder exstrophy, undescended testes, incomplete intestinal rotation, pulmonary dysplasia, and angular malformation of the inferior vena cava. Some parents mistake umbilical hernia for umbilical hernia, but in fact, there is an essential difference between the two in terms of the cause and the bulging mass. The umbilical hernia is a normal skin while the umbilical bulge is a cystic membrane. The peritoneum is the inner layer, the amniotic membrane is the outer layer, and a thin jelly-like layer is in the middle. The cystic membrane plays a protective role and changes over time. Within 6-12 hours after birth, the surface of the cystic membrane is smooth, moist, transparent and lustrous; later it becomes opaque, yellow, dry and rough, easily ruptured, which may cause naked prolapse of internal organs, shock, peritonitis and death. In a few sick children, the capsule ruptures during delivery and the abdominal organs are directly exposed. In fact, many children are diagnosed before delivery and are transferred directly from the delivery room to the pediatric surgical ward or operating room. The treatment is related to the size of the bulging mass, taking into account the respiratory and circulatory function of the child. (1) If the bulging mass is less than 5 cm (i.e., equivalent to an abdominal wall defect of less than 5 cm) and the child is otherwise in good condition, abdominal viscera can be returned and the abdominal wall can be closed in layers. (②) bulging masses of more than 5 cm, also known as giant umbilical bulge, if the bulging abdominal organs outside the body forced to return, due to excessive compression of the diaphragm and hepatic veins and inferior vena cava, is bound to cause respiratory and circulatory dysfunction of the child, so the use of staged surgery. The first time implemented shortly after birth, only free sutured skin (skin has elasticity, like wrapping skin to wrap the bulging swelling) to protect the cystic membrane; sometimes the skin is not enough to sew, can be applied outside the cystic membrane, such as sulfadiazine cream, 0.5% silver nitrate, etc., 1-2 times per day, about 1 week after a thick layer of dry scab, and on this basis the skin on both sides of the wound gradually grow together. But the above are only skin healing, about 6-12 months after the need to do again to repair the abdominal wall surgery. ③ giant umbilical bulge, a silicone capsule is sewn outside the bulging swelling to protect the capsule membrane and the bulging abdominal organs, and then the silicone capsule is tightened day by day so that the bulging abdominal organs are gradually returned and the abdominal wall is finally repaired. This method is becoming popular. Regardless of the surgical method, high intravenous nutrition is very important to ensure a smooth recovery of the child.
