Early surgical treatment of inguinal hernia is necessary because of the possibility of entrapment and serious consequences. Tension-free hernia repair surgery is now carried out in most hospitals, and this surgery has gradually replaced the traditional hernia repair surgery with features such as less damage, low recurrence rate, mild chronic postoperative pain and good comfort, and has been welcomed and recognized by the majority of patients. Li Jinlong, Department of General Surgery, Second Hospital of Jilin University However, repair materials such as polypropylene, which are widely used at present, are not suitable to be applied to pediatric or adolescent patients because of the adverse effects of wrinkling with time and inflammatory irritation to male vas deferens, etc.; it increases the probability of patch infection for patients with local infection potential. Therefore, the search or development of a new generation of patch products is on the agenda. Biopatch is a new generation of artificial repair material. It is made from biological tissues and processed by cell inactivation and desubstitution. It is absorbable, has low adverse effects on the body, and is resistant to infection, and is now widely used in the repair of inguinal and incisional hernias. The basic principle of its repair application is that it can be gradually degraded and absorbed in the body and replaced by a “fiberboard”-like structure. After about a year of placement, the patch material is almost completely absorbed and a strong “fibrous plate” structure appears at the location where the material was placed. This fibrous connective tissue is completely grown by the body’s own tissue and there is no need to worry about foreign body reactions or inflammatory irritation. For inguinal hernia in children or adolescents, for intussusception hernia with intestinal strangulation, and for young men with fertility requirements, the biopatch is undoubtedly your best choice.
