Postoperative pain and pain-related health-care contacts after open inguinal hernia repair with Adhesix™ and Progrip™: a randomized controlled trial

Abstract

Purpose: Self-fixed mesh is an alternative to suture mesh fixation in inguinal hernia repair. The aim of this study was to evaluate postoperative pain after open inguinal hernia surgery using self-fixed meshes. Methods: A randomized clinical trial comparing self-adhesive mesh (Adhesix™) and self-gripping mesh (Progrip™) was conducted from November 2018 through March 2021. Patients included were male, 18–85 years old, and suitable for day case surgery. The primary endpoint was the number of patients needing follow-up visits due to postoperative pain during the first 3 postoperative months. Secondary endpoints included the intensity of pain, the time of return to work and normal daily activities, quality of life measures and postoperative complications. Results: 270 patients were enrolled, 132 received Adhesix™ mesh (A group) and 138 Progrip™ mesh (P group), 231 (85.6%) completed 1- or 3-month follow-up. The number of patients needing follow-up for postoperative pain was significantly higher in the P group (19 vs. 4, p = 0.001). The P group had higher numeric rating scale of pain while coughing (P 0.50 vs. A 0.20, p = 0.024) and during exercise (P 1.02 vs. A 0.60, p = 0.057) at 3 months postoperatively. The time of return to normal activity was 16.6 days in the A group and 22.9 days in the P group, (p = 0.004). The postoperative day being fit for work was sooner for the A group (14.3 days vs 17.8 days, p = 0.009). Conclusion: This study demonstrated an advantage of self-adhesive mesh over self-gripping mesh with respect to acute postoperative pain and thus faster recovery after surgery.
