Laparoscopic versus open inguinal hernia repair: randomised prospective trial.
Laparoscopic surgery benefits patients because it reduces pain and enables earlier mobilisation. There is concern that laparoscopic hernia repair may enter surgical practice without proper evaluation. We have done a randomised, prospective study comparing laparoscopic and open inguinal hernia repair performed under day-case general anaesthesia. 150 patients were randomised to have laparoscopic (group L) or open (group O) herniorrhaphy. Group L underwent transabdominal stapling of preperitoneal Prolene mesh. Group O underwent open repair, with a tension-free nylon darn. Postoperatively patients completed pain analogue scales eight times over 7 days, and use of analgesia was recorded. Time of return to normal domestic activity and to work was assessed. The groups were similar in age, sex, and body surface area. Self-administered co-proxamol was a median of 18 tablets (1 tablet = 325 mg) in group O (n = 75) and 6 in group L (n = 75, p < 0.001). Overall mean pain analogue score was 3.1 (SD 1.8, n = 70) in group O and 1.8 (SD 1.1, n = 71) in group L (p < 0.0001). Return to normal domestic activity was a median of 7 days in group O (n = 72) and 3 days in group L (n = 73) (p < 0.001). Return to work was a median of 28 days in group O (n = 39) and 14 days in group L (n = 40) (p < 0.002). These data suggest that laparoscopic hernia repair induces less pain than open hernia repair, and enables patients to return to normal activity and work more quickly.
