With the improvement of medical equipment and the popularization of minimally invasive technology, adult inguinal hernia repair surgery using laparoscopic technology has been widely carried out all over the world and the surgery has become mature and definite. The results have been well received by patients with hernia and have been reported in the local media for many times. Adult inguinal hernia is caused by the weakness of the abdominal wall, which is like a piece of clothing that has been worn out and has a “hole”, and hernia surgery is to mend the clothing. Traditional surgery emphasizes “stitching”, but stitching on some rags will certainly result in easy re-rupture; whereas modern hernia surgery is a tension-free repair, which emphasizes “patching”, that is, using a suitable patch to fill the “hole” in the body. It is like taking a new piece of cloth and patching an old dress. The advantage is that it is tension-free, less traumatic, less painful, faster recovery and significantly less recurrence rate after surgery. The key is how the patch is placed to repair the “hole”. In contrast to open surgery, where the abdominal wall is cut from the outside to the inside layer by layer and then the patch is placed, laparoscopic surgery is performed by placing the patch directly from the innermost layer, which simply means that the patient enters the abdominal cavity through the laparoscope and repairs the hernia with the patch from the inside. Its advantages include: less trauma, faster recovery, less complications, lower recurrence rate, and at the same time, it can deal with bilateral hernias and avoid the hidden danger of secondary surgery. Patients can get out of bed and eat on the same day after surgery and be discharged from the hospital 1 to 2 days after surgery, and there is no need to restrict physical activities after surgery, and they can go to work normally 3 to 5 days after surgery. Laparoscopic hernia repair has more obvious advantages for various complicated and difficult diseases such as umbilical hernia, abdominal white line hernia, incisional hernia of abdominal wall, parastomal hernia, esophageal hiatal hernia, etc. It can significantly reduce the hospitalization time, and patients can recover quickly after surgery with less pain and lower recurrence rate.
