An abdominal wall hernia is a localized “mass” of intra-abdominal organs or tissues that protrudes to the body surface through a fissure, fascial weakness or defect in the abdominal wall. It is a common surgical condition with many different types. They are named according to the location or cause of the protrusion, such as inguinal hernia, femoral hernia, umbilical hernia, parastomal hernia and incisional hernia. Among them, inguinal hernia is the most common extra-abdominal hernia, accounting for 90% of all extra-abdominal hernias. Incisional hernia of the abdominal wall is a common complication after abdominal surgery, with an incidence of about 2%-11%. Its occurrence is related to local and systemic factors such as incision type, suture material and technique, incisional infection, obesity, malnutrition, advanced age, diabetes mellitus, and chronic obstructive pulmonary disorders. The recurrence rate after conventional hernia repair can be as high as 30-50%, causing great pain to the patient. The incidence of parastomal hernia is generally considered to be about 10%, with an average onset of 15 months after surgery and the majority of hernias (62%) occurring within 2 years after stoma surgery. Traditional abdominal wall hernia repair is highly traumatic, has a high recurrence rate, and is prone to wound contamination and repair failure if parastomal hernia repair is performed. The application of laparoscopic technology for the diagnosis and treatment of ventral wall hernia shows the advantages of less trauma, clear diagnosis, complete repair and fast recovery, and is the best choice for the treatment of modern types of ventral wall hernia. At present, transperitoneal anterior peritoneal mesh implantation (TAPP) and total extraperitoneal mesh implantation (TEP) are 2 common methods of laparoscopic minimally invasive treatment of inguinal hernia, which well solve the problem of high recurrence rate of conventional inguinal hernia surgery, and the high cost of treatment is its disadvantage compared with conventional surgery, but laparoscopic minimally invasive surgery is popular among patients because of the light postoperative pain, short bed rest time and short time needed to resume work. It is especially advantageous for the following three types of patients: 1. bilateral inguinal hernia, especially when the contralateral occult hernia can be found intraoperatively; 2. recurrent hernia after conventional surgery; 3. combined surgery means combined treatment of inguinal hernia when there are other diseases in the abdominal cavity that require laparoscopic surgery.
