Background: Of various endoscopic hernia repair procedures, TAPP and TEP have been selected for routine use.
Methods: Results from Medline research were analysed.
Results: There is a similar risk for postoperative morbidity for both techniques. The recurrence rate in large single-centre series is between 0% and 3.4%. There were numerous indications for both procedures, whereby a transperitoneal TAPP can also be applied in cases of previous preperitoneal operations.
Conclusion: Randomised trials comparing both methods of hernia repair are lacking. Seven non-randomised studies showed no differences in recurrence rate and morbidity. In general the learning curve for is shorter in favour of TAPP repair.
