Open or laparoscopic preperitoneal mesh repair for recurrent inguinal hernia? A randomized controlled trial.
BACKGROUND
Giant prosthetic reinforcement of the visceral sac (GPRVS), an open preperitoneal mesh repair, is a very effective groin hernia repair. Laparoscopic transabdominal preperitoneal repair (TAPP), based on the same principle, is expected to combine low recurrence rates with minimal postoperation morbidity.


METHODS
Seventy-nine patients with 93 recurrent and 15 concomitant primary inguinal hernias were randomized between GPRVS (37 patients) and TAPP (42 patients). Operating time, complications, pain, analgesia use, disability period, and recurrences were recorded.


RESULTS
Mean operating time was 56 min with GPRVS versus 79 min with TAPP (p < 0. 001). Most complications were minor, except for a pulmonary embolus and an ileus, both after GPRVS. Patients experienced less pain after a laparoscopic repair. Average disability period was 23 days with GPRVS versus 13 days with TAPP (p = 0.03) for work, and 29 versus 21 days, respectively (p = 0.07) for physical activities. Recurrence rates at a mean follow-up of 34 months were 1 in 52 (1.9%) for GPRVS versus 7 in 56 (12.5%) for TAPP (p = 0.04). Hospital costs in U.S. dollars were comparable, with GPRVS at $1,150 and TAPP at $1,179.


CONCLUSIONS
Laparoscopic repair of recurrent inguinal hernia has a lower morbidity than GPRVS. However, laparoscopic repair is a difficult operation, and the potential technical failure rate is higher. With regard to recurrence rates, the open preperitoneal prosthetic mesh repair remains the best repair.
