Tension-free Laparoscopic and Open Hernia Repair: Randomized Controlled Trial of Early Results

Abstract.

The aim of the study was prospectively to compare the early results and outcome in 105 patients randomly allocated to undergo tension-free laparoscopic hernia repair (LHR) with transabdominal preperitoneal technique (53 patients) or open hernia repair (OHR) with mesh apposition (52 patients). The mean (SD) operation time was longer in the LHR group than in the OHR group: 49.6 (5.4) versus 33.9 (6.2) minutes; p < 0.001. One laparoscopic case was converted to open repair to deal with a hemorrhage from an aberrant obturatory artery at the level of Cooper's ligament. Groin discomfort or pain was the most common complication after both procedures. The patients requiring none, one, two, or more than two doses of intramuscular diclofenac were, respectively, 40.4%, 40.4%, 15.4%, and 3.8% after LHR and 50.0%, 30.8%, 17.3%, and 1.9% after OHR (p= 0.69; NS). The mean ± SEM (range) postoperative visual analog scale score, ranging from 0 (no pain) to 10 (worst pain imaginable), was 3.1 ± 0.2 (1–7) in the LHR subset and 2.7 ± 0.2 (1–5) in the OHR group (p= 0.14; NS); on the second postoperative day the score was 2.3 ± 0.2 (1–6) and 1.8 ± 0.1 (1–4), respectively (p < 0.03). The time ± SEM (range) of resumption of pain-free normal activities and work was faster in OHR group: 6.1 ± 0.2 (4–8) weeks versus 6.5 ± 0.1 (4–8) weeks; p < 0.03. Our results showed that tension-free open hernia repair is superior to LHR in terms of postoperative pain with no important differences in recovery.
