Inguinal hernia, commonly known as “small intestine gas”, is formed by the protrusion of intra-abdominal organs or tissues, together with the peritoneal wall layer, through the weak point of the abdominal wall to the body surface. If left untreated, the hernia will gradually increase in size over time, and when the patient suddenly exerts abdominal force, more intestinal tubes will protrude from the defective area, resulting in intussusception of the hernia contents, which may cause intestinal obstruction and even life-threatening necrosis of intestinal strangulation. There are many methods of inguinal hernia repair, and traditional hernia repair has been replaced by tension-free hernia repair due to high postoperative complications and postoperative recurrence rate (10%-15%), which uses artificial biomaterial as a patch to strengthen and repair the posterior wall of the inguinal canal and prevent protrusion of abdominal contents to treat inguinal hernia. ~The recurrence rate is about 1%, and the abdominal wall will be left with a 4-5 cm incision scar. Laparoscopic hernia repair is a laparoscopic tension-free hernia repair, in which two 5-mm and one 10-mm holes are usually made in the abdominal wall, and the entire operation is completed with a patch and a staple gun. The use of multiple patches, which are larger than those used in the repair of a tensionless hernia, and the placement of the patch in the superficial layer of the peritoneum should have a lower recurrence rate.
