The concept of tension-free hernioplasty was first proposed by American physician Lichtenstein in 1986. This kind of repair with artificial biomaterials as a patch to strengthen the posterior wall of the inguinal canal, this method overcomes the traditional surgery (i.e., without patch suture repair method) on the normal tissue anatomical structure of the interference, the level is clear, and after the repair of the surrounding tissues are tension-free, so it is named “tension-free hernioplasty”. Currently commonly used flat piece of tension-free hernia repair and hernia ring filling tension-free hernia repair and laparoscopic tension-free hernia repair. Inguinal hernia is a common disease in general surgery and requires surgical treatment. The development of inguinal hernia repair has a history of more than 100 years, and the focus of the improvement of the operation is to repair the weak area of the abdominal wall tension-free without changing the normal anatomy of the inguinal area as much as possible. In the last 10 years, the introduction of tension-free repair techniques and new artificial materials has gradually replaced traditional hernia repair and is considered a revolution in the history of hernia treatment. This procedure has the advantages of short operation time, short hospitalization time, fast recovery and low recurrence rate.
