Pediatric syringomyelia is a common condition in children that occurs when the duct from the abdominal cavity to the scrotum (sphincter) does not close, allowing abdominal fluid to flow into the sphincter of the groin or scrotum, forming a collection of fluid. If the sphincter is thicker, the intestinal canal or omental fat from the abdominal cavity descends into the groin and scrotum, forming an inguinal hernia (commonly known as “hernia” or “small intestine gas”). Therefore, the etiology of pediatric syringomyelia is similar to that of inguinal hernia because the syringomyelia is not closed. Children with syringomyelia show enlarged, translucent groin or scrotum, which can increase in size during activity and crying, and decrease in size after resting flat. Children with syringomyelia within one year of age may heal on their own and may not be operated on urgently. After one year of age, it is less likely to heal on its own, so surgery is feasible. However, if the tension is high, it may affect the blood circulation of the testicles and lead to testicular atrophy, then surgery should be performed as soon as possible. The surgical methods are open surgery and minimally invasive laparoscopic surgery. The purpose of surgery is to ligate the sphincter at a high level so that the abdominal fluid cannot enter the unclosed sphincter and cure it. In the past, open surgery was commonly used, but in recent years laparoscopic minimally invasive surgery has been used more often and has become mainstream. It has the following advantages: less injury, simple operation; simultaneous investigation and treatment of contralateral occult syringomyelia or occult hernia; low recurrence rate; small, concealed and beautiful incision; short operation time. After its application, it is widely welcomed by parents. However, the cost of minimally invasive surgery is slightly higher than that of open surgery. There are still a few recurrences of syringomyelia after surgery, and recurrence needs to be treated by surgery again. Paying attention to rest after surgery can reduce the recurrence rate. The recurrence rate after minimally invasive laparoscopic surgery in our hospital is less than 1%.
