To explore the clinical significance of the programmed " four-space" technique for the establishment and subdivision of extraperitoneal space in laparoscopic Total Extraperitoneal (TEP) Herniorrhaphy.

A total of 120 adult male patients with oblique inguinal hernia underwent TEP from July 2017 to November 2019 were randomized into four-space group (60 cases) and traditional group (60 cases), according to different surgical procedures. The SPSS 20.0 software were used for statistical analysis. The count data such as perioperative indicators in the two groups were expressed as (±s), and were examined by using the independent t test. Count data such as postoperative complications were tested by using χ²; A P value of <0.05 was considered as statistically significant difference.

The operation was completed successfully in both groups, and there was no case of conversion to open herniorrhaphy. The postoperative hospital stay, operation time and intraoperative bleeding in the four-space group were shorter or lower than those in the traditional group respectively (P<0.05). The incidence of peritoneal rupture, seroma, inferior epigastric artery injury and postoperative chronic pain in the four-space group was lower than those in the traditional group respectively (P<0.05). There was no significant difference between the two groups in terms of the incidence of wound infection and hernia recurrence (P>0.05).

In TEP group, establishment and subdivision of the extraperitoneal space by using the programmed " four-space" technique could improve the quality and safety of surgery, could reduce surgical complications, and is worthy of promotion.
