Inguinal hernias in adults are not self-healing and surgery is the only reliable treatment for inguinal hernias. Early detection and treatment have better results and fewer complications. Traditional surgery emphasizes “sewing”, just like taking a thick silk thread to sew up the hole directly when the clothes are torn, while modern tension-free hernia repair surgery emphasizes “patching”, which means using a suitable patch to patch up the hole, characterized by tension-free, small incision, less trauma, less pain and faster recovery. It can be done on an outpatient basis under local anesthesia, without hospitalization, without fasting before and after surgery, without bed rest and accompaniment after surgery, and with low complication and recurrence rates. It is reported in domestic and international literature that the surgical results of hernia specialists are significantly better than those of general surgeons.
