The application of minimally invasive laparoscopic techniques for inguinal hernia repair has become a safe and effective method for the treatment of inguinal hernia with the maturation of laparoscopic techniques and the development of material science, and has gradually become the first choice for patients due to its minimal surgical trauma, rapid postoperative recovery, low recurrence rate, and compliance with physiological laws. Laparoscopic inguinal hernia repair requires implantation of a patch in the lateral peritoneal region in the weak part of the inguinal region and can be divided into two different procedures depending on the route of patch placement: transabdominal preperitoneal repair (TAPP) and complete extraperitoneal repair (TEP). The former involves first entering the peritoneal cavity, making a 7-10 cm incision in the peritoneum, placing the patch anteriorly and then suturing the peritoneal incision; the latter involves entering directly from the superficial layer of the abdominal wall, reaching the anterior peritoneum and separating to create a space for placement of the patch without incising the peritoneum and entering the peritoneal cavity. The two procedures have their advantages and disadvantages: TAPP is a straightforward procedure that meets the vision and operating habits of most surgeons, and its basic operation is not too difficult, with the disadvantage that it requires incision of the peritoneum and some disturbance of the abdominal cavity, which may produce a certain degree of adhesions and is not suitable for patients with extensive abdominal adhesions, and the patch needs to be fixed to the anterior abdominal wall. The disadvantage of TEP is that it requires a higher operative skill and is slightly more difficult to perform, and it is not suitable for patients with a longer history or larger hernias. In the author’s opinion, after a certain number of surgical experiences, both surgical approaches are safe and effective and there is no difference in technical difficulty. The key is to choose the appropriate surgical approach for the patient according to the physical condition of different patients, the condition of the inguinal hernia and the local anatomical situation.
