To study the clinical effect of self-fixation mesh in laparoscopic totally extra-peritoneal hernia repair (TEP).

The clinical data of 88 patients with inguinal hernia admitted to our hospital from July 2016 to June 2018 were retrospectively analyzed, they were divided into the experiment group (n=55) and the control group (n=33) according to the different meshs. TEP was performed in both groups, the control group was placed in polypropylene plain film, the experiment group was placed in a self-fixation mesh. The clinical parameters of the 2 groups, the VAS scores at different time before and after surgery, the postoperative complications, the recurrence of hernia and the postoperative analgesia medication of the two groups were compared.

The paving mesh time and operative time in the experiment group were significantly shorter than the control group (P<0.05), there was no significant difference in the operation time and postoperation spontaneous activity time between the two groups (P>0.05). The VAS scores from 2 h to 3 d postoperation of the two groups first increased and then decreased, and they were significantly lower than preoperation (P<0.05), the VAS scores from 2 hours to 3 days postoperationin the experiment group was significantly lower than the control group (P<0.05). The incidence of complications in the experiment group was significantly lower than the control group (P<0.05), and there was no recurrence in the two groups followed up for 6 months. Compared with the control group, the proportion of additional analgesic medication, medication time and medication dose in the experimental group were significantly reduced (P<0.05).

Insertion of the self-fixation patch during TEP can significantly reduce the incidence of postoperative pain, reduce the use of analgesics and have fewer postoperative complications, it's safe and effective.
