To show the effectiveness of tension-free hernioplasty for inguinal hernia repair. We studied 106 patients who underwent inguinal hernia repair, as conventional hernioplasty in 52 and as tension-free hernioplasty in 54. We analyzed the operation time, postoperative complications, pain, time to resume daily activities, and frequency of recurrence in the short and long term. The average age of the patients was 46.2 years. The operation time was significantly shorter in the tension-free group than in the conventional group, at 33 +/- 11.1 versus 49 +/- 8.8 min, respectively (P < 0.05). The overall complication rate was 10%, being 1.5% in the tension-free group and 13% in the conventional group (P = 0.4). The visual-analogue pain scores after surgery were lower in the tension-free group than in the conventional group (P = 0.01). Patients in the tension-free group returned to their normal activities sooner than those in the conventional group (P < 0.05). Tension-free hernioplasty resulted in less pain and allowed patients to return to their daily activities sooner than conventional hernioplasty.
