The current effective treatment for adult hernia is surgical repair with synthetic or biological patches to strengthen the abdominal wall defect and return the protruding hernia contents to the abdominal cavity, either open or laparoscopic. Of all the procedures available, the most effective, with the least chance of recurrence and the fastest recovery time, is laparoscopic total extraperitoneal repair (TEP). TEP is characterized by the fact that all instruments or operations are performed without entering the human abdominal cavity, and the hernia sac is separated and retracted and the patch is fixed in the abdominal wall space outside the peritoneum, without complications such as intestinal adhesions caused by other procedures such as intraperitoneal high ligation and repair, neuropathic lower limb pain caused by patch fixation, or vascular accidental injury. Since the patch does not enter the abdominal cavity and is located in the thick abdominal wall, the local foreign body sensation is not obvious after surgery, and naturally the patient feels that the abdominal muscle is still soft after surgery, as if no surgery has been performed, and the phenomenon of stiffness of the belly rarely occurs. The patch is located deep in the abdominal wall, and the postoperative pain is relatively mild, and the patient feels good subjectively after surgery. Basically, the patient can be discharged within a day or two after the extraperitoneal surgery is performed. This is by far the most cosmetic approach, with only three tiny scars in the midline of the lower abdomen (the scar 1.5 cm below the umbilicus is about 1 cm) and two scars less than 0.5 cm, which are barely visible visually after cosmetic suturing. Compared to open tension-free hernia repair (skin incision of 3 to 4 cm), it looks much better and, crucially, there is no local foreign body sensation when the patch is placed in the abdominal wall. The incidence of postoperative hematoma formation and chronic pain is very low, and it does not affect the movement of the lower limbs. In 2013, it was recommended as a standardized procedure for doctors with laparoscopic experience and surgical experience by the Chinese Medical Association’s Guide to Standardized Laparoscopic Operation of Inguinal Hernia. It has gradually become popular in China. Our general surgery department is the first to perform this procedure in the Zhongshan City area, and it is an effective and safe treatment procedure with quick recovery.

The incidence of hematoma formation and chronic pain after laparoscopic complete extraperitoneal repair is very low and does not interfere with the movement of the lower extremities, which is the most significant therapeutic advantage and has a very low recurrence rate of postoperative hernia.
