To compare the application effect of lightweight large-pore polypropylene mesh and self-adhesive mesh in Lichtenstein hernia repair.

A total of 60 unilateral male inguinal hernia patients in the Second Hospital of Jilin University from January to March 2021 were selected for a prospective randomized controlled study. They were randomized into the lightweight large-pore polypropylene mesh group (n=30) and the self-adhesive mesh group (n=30). A tension-free repair using the Lichtenstein technique was performed on all patients. The general data, operation related indicators, postoperative average hospital stays, seroma, mesh infection, postoperative pain, recurrence, foreign body sensation and hospital cost were compared between the two groups, to evaluate the effect of the two types of mesh.

There were no significant differences in general data, anesthesia method and postoperative hospital stay between the two groups (P>0.05). There were significant differences in average operating time and hospital cost between the two groups (P<0.05). There were no significant differences in seroma, short-term postoperative pain (7 day and 1 month) and chronic pain, mesh infection, local discomfort or foreign body sensation, recurrence and other complications.

The self-adhesive mesh can significantly shorten the operation time, but the medical cost is significantly higher than that of the lightweight large-pore polypropylene mesh. And there was no significant difference in postoperative recurrence, chronic pain and other complications.
