umbilical hernia
Introduction
Introduction to umbilical hernia Umbilical hernia refers to the extra-abdominal hernia that protrudes from the weak area of the umbilicus. The umbilicus is located in the middle of the abdominal wall and is the most closed part of the abdominal wall during embryonic development. The umbilical part lacks adipose tissue, and the skin, fascia and peritoneum of the outermost layer of the abdominal wall are directly connected together, and become the weakest part of the abdominal wall. The contents of the abdominal cavity are easy to protrude from this part to form the umbilical hernia. Clinically divided into infant umbilical hernia and adult umbilical hernia. The former is much more common than the latter. basic knowledge The proportion of illness: 0.83% (the above is the probability of illness in infants and young children) Susceptible people: no specific population Mode of infection: non-infectious Complications: umbilical inflammation
Cause
Umbilical hernia
Baby umbilical hernia (45%):
It is congenital, the cause of the disease is umbilical hypoplasia, the umbilical ring is not completely locked; or the scar tissue of the umbilicus is weak, not strong enough, in the case of increased intra-abdominal pressure, (often sputum, constipation, phimosis, etc.), the internal organs can It is formed by protruding from the umbilicus, and the cover is only scar tissue, subcutaneous and skin.
Adult umbilical hernia (25%):
It is rare, and may be related to the weakening of scar tissue at the umbilical ring. The cause is pregnancy, chronic cough, ascites, etc. The early part of the sputum is mostly the omentum, followed by the small intestine, colon, etc., often due to the occurrence of the sac wall. Extensive adhesion, forming a multi-atrial gap.
Prevention
Umbilical hernia prevention
Pediatric umbilical hernia has a self-healing tendency, and generally requires surgery. Adult umbilical hernia is associated with increased abdominal pressure, such as pregnancy, cirrhosis, etc. If there is no incarceration, surgery should be cautious.
Complication
Umbilical hernia complications Complications
Pay attention to prevent complications such as umbilical inflammation caused by umbilical compression.
Symptom
Umbilical hernia symptoms Common symptoms Indigestion Abdominal discomfort Umbilical week is obviously red and swollen. There are cherry red in the umbilical fossa...
1. Infant umbilical hernia: more common, mostly easy to relapse, incarceration is rare, when crying, standing and using force, the umbilicus expands out of the mass, usually 1 to 2 cm in diameter, no other symptoms, often in the bath, changing clothes Unintentionally discovered.
2. Adult umbilical hernia: more common in middle-aged obese women, the main symptoms are hemispherical lumps in the umbilicus, which can be returned, often accompanied by indigestion, abdominal discomfort and dull pain, because the ankle ring is generally smaller and the surrounding scar tissue is tougher. Therefore, the incarceration and strangulation are more likely to occur, and the huge umbilical hernia is suspended.

Regular physical inspection. Hepatic angiography and B-ultrasound are helpful in distinguishing from other abdominal wall diseases.
Diagnosis
