A case of inguinal hernia in a juvenile was recently completed. The operation was successful and the postoperative recovery was smooth with no complications seen in the short term. The patient was a 14-year-old male, 178 cm tall, weighing 80 kg, with a recurrent right inguinal reversible mass for 13 years, and had suffered from asthma as a child, which has now been cured. According to the intraoperative exploration, the patient had a small hernia sac and a strong posterior wall of the inguinal canal. The Ferguson method (Fulkerson’s method, Ferguson’s method) was used to repair the hernia after high ligation of the hernia sac. Ferguson’s method inguinal hernia repair is indicated in cases with a small hernia sac and a strong posterior inguinal wall. It is characterized by not freeing the spermatic cord and only strengthening the anterior wall of the inguinal canal in front of the spermatic cord. It is usually used in adolescents. This method of repair is used less often in clinical practice and many young surgeons have not even seen this procedure. The main reason for this is the small number of suitable cases – the incidence of inguinal hernia in adolescents is currently relatively low. Juvenile inguinal hernias cannot be repaired with patches, and placement of a general patch repair is not recommended in young people (especially those who have not had children); a biopatch may be considered, although it is more expensive and has been used clinically for a short period of time and experience is still scarce.
