Periumbilical abdominal wall defect

Introduction Gastroschisis, also known as visceral valgus, refers to the true defect of the umbilical paraabdominal wall during embryonic development, with abdominal visceral prolapse, completely without skin and peritoneal coverage. Body stalk anomaly is a serious chest wall and abdominal wall defect. Due to various reasons, the formation of the pedicle fails, resulting in no umbilical cord and no chest and abdomen wall. The most common cause of abdominal dissection is amniotic membrane syndrome.

Cause

Its occurrence is closely related to chromosomal abnormalities. In the late stage, more amniotic fluid was combined.

Ultrasound is characterized by an outwardly protruding mass in the umbilical cord of the fetus. The size is different, the edge is clear, the outer surface is covered with a capsule, and the umbilical cord is attached to the top of the mass. The inside of the mass can be the echo of the intestine, and the larger umbilical bulge can be seen. The mass contains a substantial organ such as the liver, and color Doppler ultrasound shows that the umbilical blood vessels are visible at the edge of the mass. It should be noted that small and large umbilical bulge is easy to miss diagnosis. The former has a small mouth and is difficult to find; the latter has a normal abdominal contour and only the abdominal wall is thin.

Ultrasound has a high diagnostic rate for umbilical bulging, and it can determine its extent and guide further treatment. After the diagnosis, the fetus is determined depending on the situation. If the fetus has no chromosomal abnormalities, the bulging mass is small, and the surgery is repaired after the birth, and good results can be obtained.

Bladder exstrophy refers to the absence of the inferior abdominal wall and the anterior wall of the bladder. The posterior wall of the bladder is exposed outside the abdominal wall and is formed due to an abnormal bulging of the lower abdomen during the embryonic period.
