Background: Postoperative chronic pain is a major drawback of inguinal hernia repair. The current objective was to compare the frequency of chronic pain after laparoscopic (Totally Extraperitoneal Patch – TEP) and open (Lichtenstein) repairs.
Methods: A randomized multicentre study with five years follow-up was conducted on male patients with a primary inguinal hernia. This report concerns chronic pain which was categorized as mild, moderate or severe by blinded observers. A subgroup analysis was performed on patients who had experienced moderate or severe pain at any time during follow-up.
Results: Overall, 1370 of 1512 randomised patients underwent surgery, 665 in the TEP and 705 in the Lichtenstein group. The total incidence of chronic pain in the TEP and the Lichtenstein groups, respectively, was: 11.0 versus 21.7 per cent (one year), 11.0 versus 24.8 per cent (two years), 9.9 versus 20.2 per cent (three years) and 9.4 versus 18.8 per cent (five years) (P < 0.001). After five years, 1.9 per cent of patients in the TEP and 3.5 per cent in the Lichtenstein group reported moderate or severe pain (P = 0.092). Of the 121 patients who had reported moderate or severe pain 72 patients (60.0%) no longer reported pain after a median period of 9.4 (6.7-10.8) years after operation.
Conclusion: Five years after surgery only a few per cent of patients still reported moderate to severe chronic pain. Laparoscopic inguinal hernia repair led to less chronic pain than open repair.
