There is only one randomized controlled trial comparing TAPP with TEP repair13. In this RCT, 52 patients were randomized to either TAPP or TEP. The study showed that the 2 techniques were similar with regard to the complications, time to return to activities and hernia recurrence. However, the length of stay was shorter in the TAPP group (3.7 vs 4.4 days; p=0.03).
