Background
The aim of this study was to assess whether the application of a lightweight mesh for mesh plug repair (MPR) for primary inguinal hernia could reduce chronic pain or other symptoms associated with the insertion of the prosthesis.
Methods
Patients over 20 years of age with a unilateral primary inguinal hernia were eligible to participate in the study. The patients were randomly assigned to a lightweight mesh (LWM) or a heavyweight mesh (HWM) group. All the operations were performed under local anesthesia. The operative details, including the hernia type and the nerves that were identified, and the postoperative complications were recorded. All follow-up and outcome measures were obtained based on a physical examination and a questionnaire regarding pain and other symptoms at 1 week, 1, 3, 6, and 12 months after the surgery in a double-blinded manner.
Results
The use of LWM significantly reduced foreign body sensation after 12 months to one-third of the incidence reported for the use of HWM (5.8 vs. 17.9 %; P = 0.013), while no significant differences were found in pain parameters, including the use of pain relief medications, between the groups throughout the study period.
Conclusion
This study indicated that the use of LWM in the MPR decreases the incidence of foreign body sensation at 1 year after surgery for primary inguinal hernia. LWM may be preferable to MPR, similar to results described previously for Lichtenstein repair.
