Abstract:

BACKGROUND: Increasing clinical studies have reported the application of self-fixating mesh in the tension-free repair of inguinal hernia, but whether the self-fixating mesh is superior to the common suture mesh is still in dispute.
OBJECTIVE: To compare the effects of self-fixating polypropylene/poly(lactic acid) mesh and polypropylene mesh on chronic pain after tension-free repair of inguinal hernia.
METHODS: A total of 90 male patients with primary inguinal hernia were randomly divided into two groups: self-fixating mesh and control groups (n=45 per group). All patients underwent tension-free hernioplasty followed by self-fixating polypropylene/poly(lactic acid) mesh in the self-fixating mesh group and polypropylene mesh in the control group. Operation time and length of hospital stay were recorded; complications and recurrence rate in the two groups were observed at 6 months after operation; and postoperative pain and chronic pain were assessed by the visual analog scale (VAS) at postoperative 1, 10 days, 1, 3, 6 months.
RESULTS AND CONCLUSION: (1) Compared with the control group, the operation time was shorter in the self-fixating mesh group (P < 0.05), but there was no significant difference in the length of hospital stay between the two groups. (2) The VAS scores showed no significant difference between the two groups at postoperative 1 day, but the VAS scores were significantly better in the self-fixating mesh group than the control group at 10 days, postoperative 1, 3, 6 months (P < 0.05). (3) During the 6-month follow-up, there were no urinary retention, subcutaneous hematoma, wound infection and recurrence in the two groups except five patients in the control group who complained of a foreign body sensation. To conclude, compared with the traditional polypropylene mesh, the use of self-fixating polypropylene/poly(lactic acid) mesh can shorten operation time and reduce pain and discomfort of patients with unilateral inguinal hernia undergoing tension-free hernioplasty.
