To explore the clinical application of laparoscopic total extraperitoneal hernia repair (TEP) and open tension-free hernia repair in the treatment of inguinal hernia.

70 patients with inguinal hernia treated in Luzhong Hospital, Peking University Medical College from February 2018 to February 2019 were selected as the research subjects. They were divided into two groups according to different surgical methods, with 35 patients in each group. Group A was treated with TEP and group B was treated with open tension-free hernia repair. The operation time, intraoperative bleeding, preoperative and postoperative pain visual analogue scale (VAS), preoperative and 3 days postoperative stress response indexes, postoperative complications and total treatment cost were compared between the two groups.

The operation time and intraoperative bleeding in group A were significantly lower than those in group B (P<0.05); The postoperative VAS score of group A was significantly lower than that of group B (P<0.05); The indexes of stress response 3 days postoperative in group A were significantly lower than those in group B (P<0.05); The incidence of postoperative complications in group A was significantly lower than that in group B (P<0.05); The total treatment cost of group A was significantly higher than that of group B (P<0.05).

The clinical efficacy and safety of TEP is significantly better than that of traditional laparotomy, but the total treatment cost is more expensive. Clinicians can make reasonable choices according to the patient's own tolerance and the patient's economic level.
