Scientific and formal hernia surgery has gone through three stages: tension repair, low tension repair, and tension-free repair. Tension-free repair surgery using mesh repair has the lowest recurrence rate and is the most scientific repair method. The earliest surgical method invented by medical predecessors was the tense repair method, which means that the hernia defect, that is, the tissues on both sides of the hole, are pulled together hard and have a tendency to separate to both sides, and one side is muscle, which cannot withstand long time tearing and the repaired hole is prone to recurrence (burst open again and a hole appears again), with a recurrence rate of about 20%. Later, the French surgical predecessor Shoudice invented a surgical method to strengthen the posterior wall of the inguinal canal transversalis fascia, later called Shoudice surgery, Chinese harmonics “Shoudice love”, the operation to the two sides of the tension of the separation is lower, so the recurrence rate is also greatly reduced, about 2% to 5% or so. In recent years, artificial mesh has been commonly used at home and abroad to repair hernias, which is a tension-free repair method. The reasoning is the same as repairing a tire or clothing. If a tire or clothing has a large hole, it is easy to split by gluing it up directly or sewing it up with thread, but it is much stronger by applying a piece.
