There are umbilical hernia, white line hernia, incisional hernia, hiatal hernia, ventral hernia, femoral hernia and closed-hole hernia, etc. Traditional surgery is performed by making a 6-15 cm incision in the corresponding part of the abdominal wall, which is very traumatic to the patient and has a high recurrence rate. Laparoscopic hernia repair can be successfully completed with a tiny incision of 0.5-1 cm, which reduces the trauma caused by large incisions and the recurrence rate, and is the best choice for recurrent hernia, bilateral hernia and occult hernia. Indications for laparoscopic hernia repair: 1, inguinal hernia in infants and children, occult hernia in adults found during other laparoscopic procedures. In adults, complete extraperitoneal laparoscopic hernia repair (TEP) can be performed for inguinal hernia, hiatal hernia and femoral hernia, including bilateral hernia with a small hernia sac. In adults with inguinal hernia, hiatal hernia and femoral hernia, including refractory hernia and postoperative recurrent sliding hernia with a large hernia sac, transperitoneal anterior mesh repair (TAPP) can be performed. The advantages of laparoscopic hernia repair are: laparoscopic hernia repair is less invasive, reduces postoperative pain and discomfort, shortens the recovery time, and enables a quicker return to normal activities; TAPP can diagnose and treat intra-abdominal lesions at the same time; TEP does not enter the abdominal cavity and does not interfere with intra-abdominal organs, which fundamentally eliminates the occurrence of postoperative adhesive bowel obstruction. It is particularly suitable for the treatment of recurrent hernia, bilateral hernia and occult hernia, with low recurrence rate and is a cosmetic surgical procedure.
