The vast majority of pediatric inguinal hernias and syringomyelia are essentially the same disease and can be collectively referred to as syringomyelia. The testis enters the scrotum from the upper part of the retroperitoneum during development to form a peritoneal sheath (the round ligament of the girl’s uterus enters the labia majora), and after birth the sheath should be closed but it is not closed. The hernia may heal itself before the age of half a year, and if there is no incarcerated hernia, surgery can be performed at the age of half a year, which is minimally invasive laparoscopic surgery in our hospital. Another condition is syringomyelia, in which fluid from the abdominal cavity enters the scrotum through the unclosed syringomyelia, just like a hernia, but with different contents. However, there is a type of syringomyelia that requires early surgery, just like hernia, and that is traffic syringomyelia, characterized by: the contents are water, but they disappear quickly by squeezing or lying down, and ultrasound can confirm that it is clearly connected to the abdominal cavity.
