Many people are aware of the so-called “minimally invasive surgery” for inguinal hernia, that is, laparoscopic hernia repair, but few people, except hernia specialists, know the exact surgical procedure for laparoscopic hernia repair and do not know the difference between TAPP, TEP and IPOM. Laparoscopic inguinal hernia repair is a minimally invasive, tension-free hernia repair, and the three more commonly used clinical procedures are: intraperitoneal patch implantation (IPOM), transabdominal preperitoneal mesh repair (TAPP), and complete extraperitoneal patch implantation (TEP). However, both IPOM and TAPP have a common disadvantage: the surgical operation has to be performed in the abdominal cavity, which not only increases the risk of intraoperative abdominal organ injury and surgical complications due to pneumoperitoneum, but also may lead to postoperative abdominal adhesions and intestinal obstruction; in addition, the intracavitary anti-adhesion patch used in lPOM is expensive. Theoretically, TEP can overcome the disadvantages of the first two procedures: it is a completely extraperitoneal operation, does not disturb the normal physiological state of the abdominal cavity, the operation can achieve anatomical repair of the musculo-pubic foramen, and has few intraoperative and postoperative complications, which makes it a more ideal surgical method for the treatment of inguinal hernia, but it has high technical requirements and precise anatomical requirements. Laparoscopic total extraperitoneal repair (TEP) for inguinal hernia is based on tension-free hernia repair, plus the application of minimally invasive laparoscopic techniques to repair the musculo-pubic orifice with a patch from the complete anterior peritoneal space, which has the advantages of less pain, faster recovery and reduced impact of CO2 pneumoperitoneum on the abdominal cavity and the occurrence of intestinal adhesions. It is theoretically the more ideal method for hernia repair. However, its widespread implementation is limited by its higher technical requirements. In our department, we have performed hundreds of cases of TEP for inguinal hernia and achieved good clinical results.
