Randomized Controlled Trial
Randomized clinical trial comparing lightweight mesh with heavyweight mesh for primary inguinal hernia repair.
The aim of the present randomized clinical trial was to compare feeling of a foreign body and the early and late outcomes after inguinal hernia repair with the heavyweight (HW) mesh and lightweight (LW) mesh during a 12-month follow-up at a single specialist center. ⋯ There was no significant difference between our LW mesh and HW mesh groups in terms of chronic pain incidence, recurrence rate, and quality of life following inguinal hernia repair. However, fewer patients in the LW mesh group reported numbness around the groin or down the thigh postsurgery than did those in the HW mesh group and therein may lie in the superiority of LW mesh for inguinal hernia repair. Larger cohort studies with longer follow-up periods are required to elucidate in the future the benefits of the LW mesh.

Randomized Controlled Trial
The effect of preemptive analgesia with bupivacaine on postoperative pain of inguinal hernia repair under spinal anesthesia: a randomized clinical trial.
In the absence of any study on the use of bupivacaine as a long acting local anesthetic for the purpose of inducing preemptive analgesia in patients undergoing inguinal hernia repair under spinal anesthesia, this study was conducted to provide some evidence for possible benefits of such practice. ⋯ The pre-operative local infiltration of bupivacaine reduces pain, nausea, vomiting and opioid use in the first 24 h after inguinal hernia surgery under spinal anesthesia. Therefore, further evaluation of the efficacy of this technique as a modality of preemptive analgesia is suggested.
