- May 12, 2018 -

Pediatric hernia is one of the most common diseases in pediatric surgery and hernia surgery. It mainly includes congenital inguinal hernia and umbilical hernia. The main factor in the occurrence of pediatric hernia is congenital factors. The inguinal hernia is mainly caused by the closure of the sheath-like process. The umbilical hernia is caused by the inability of the umbilical ring to shrink in time. The premature infants and low birth weight infants are born due to incomplete growth and development at birth. . Children older than one year old can not recover from inguinal hernia. Children with umbilical hernia should be considered for surgery if they are older than 4 years old or have a umbilicus diameter of 2 to 3 cm or more. The main surgical method for children with inguinal hernia is high ligation of the hernia sac, in which the advantage of laparoscopic surgery is more obvious, and the umbilical hernia requires suture repair in addition to the removal of the hernia sac.Surgical Instruments for Laparoscopy.

Etiology

The fundamental cause of inguinal hernia in children is that the sheath sheath is not closed in time. The sheath sheath is formed due to the drop of the testis or the round ligament of the uterus and is mostly closed within one year after birth. In newborns and infants less than half-year-old sheath neurites are not fully closed, but the sheath is not closed does not form a hernia, if the baby's abdominal wall is not strong enough, such as premature infants, low birth weight children are more likely to have inguinal hernia. Other situations such as: excessive forced crying, constipation, coughing, etc. to increase the intra-abdominal pressure will also promote the formation of hemorrhoids. The drop of the right testis is generally later than that of the left side, and the sheathing process is closed for a long time. Therefore, the right inguinal hernia is more common than the left side, and the unilateral is more common than the bilateral.

The reason for the occurrence of umbilical hernia in children is that the umbilical ring is not closed. The umbilical ring is formed during the embryonic period and continues to contract as the fetus grows. The umbilical ring diameter of a normal newborn is about 1 cm. Under normal circumstances, the umbilical ring continues to shrink until it is finally closed. After the baby's umbilical cord falls off, the umbilicus scar is a congenital weakness. At the same time, in infants, the anterior and posterior rectus sheaths of both sides are not closed at the umbilicus, leaving a defect, which provides conditions for the occurrence of umbilical hernia. Various factors that increase intra-abdominal pressure, such as crying, constipation, diarrhea, and cough, can all contribute to the occurrence of umbilical hernia in children.
