Inguinal hernia biopatch is generally harmless to the human body, but after all, it is a foreign body with a potential risk of rejection and infection. Among the treatment options for inguinal hernia, tension-free hernia repair is an important one, which utilizes a new artificial polymer mesh to repair the defect without tension. Compared with traditional hernia repair, tension-free hernia repair has the advantages of faster postoperative recovery, less pain, and lower recurrence rate. The biopatch is generally harmless to the human body, and most people do not need to take it out after it has been put in for life. However, for some people, due to their own constitution and other reasons, the patch is a foreign body for them, which may cause the corresponding rejection of foreign body reaction and infection. Therefore, it is important to be careful when choosing a patch material, and the material is not recommended for emergency surgery for incarcerated hernias. For the choice of patch material, please be guided by your doctor.
