Laparoscopic Mesh Versus Open Preperitoneal Mesh Versus Conventional Technique for Inguinal Hernia Repair: A Randomized Multicenter Trial (SCUR Hernia Repair Study)

OBJECTIVE: To evaluate the influence of the laparoscopic technique in hernia repair regarding time to full recovery and return to work, complications, recurrence rate, and economic aspects. SUMMARY BACKGROUND DATA: Several studies have shown advantages in terms of less pain and faster recovery after laparoscopic hernia repair, whereas others have not, and the cost-effectiveness has been questioned. The laparoscopic technique must be thoroughly compared with the open procedures before its true place in hernia surgery can be defined. METHODS: Six hundred thirteen male patients aged 40 to 75 years were randomized to the conventional procedure, preperitoneal mesh placed by the open technique, or laparoscopic preperitoneal mesh (TAPP). Follow-up was after 7 days, 8 weeks, and 1 year. RESULTS: Of 613 patients undergoing surgery, 604 (98.5%) were followed for 1 year. Patients who underwent TAPP gained full recovery after 18.4 days, compared with 24.2 days for open mesh (p < 0.001) and 26.4 days for the conventional procedure (p < 0.001). Patients who underwent TAPP returned to work after 14.7 days, compared with 17.7 days for open mesh (p = 0.05) and 17.9 days for the conventional procedure (p = 0.04). They also had significantly less restriction in physical activities after 7 days. The TAPP procedure was more expensive, mainly as a result of longer surgical time and equipment costs, even after compensation for earlier return to work. Complications were more common in the TAPP group, with a varying pattern between the groups. Four recurrences in the conventional, 11 in the open mesh, and 4 in the TAPP group were recorded after 1 year (p = n.s.). CONCLUSION: The laparoscopic technique results in both shorter time to full recovery and shorter time to return to work, at the price of substantially increased costs.
