BACKGROUND: Previous evaluations of endoscopic hernia surgery mostly are based on small prospectively documented series or on a few randomized comparative studies. In the following, results of a large single-institution experience concerning the transabdominal preperitoneal patch (TAPP) technique with regard to the development of methods and the routine use are described. METHODS: From April 1993 to March 1997, 2,700 TAPP procedures were performed at the Department of General and Visceral Surgery, Marien-hospital, Stuttgart, Germany. The follow-up was documented prospectively in all cases by use of computed data base. RESULTS: The majority of patients (83.8%) were operated because of primary hernias. In 17.2% a first or multiple recurrence of an inguinal hernia was indicated. At a median postoperative observation period of presently 20 months and a follow-up rate of 86.5%, 28 recurrences have been determined so far (total recurrence rate 1.03%), 6 of which occurred after a recurrent hernia reparation (1.33%) and 22 after primary hernia repair (0.97%). The most common cause for recurrence was in 39.3% a mesh (12 x 8 cm) being too small. The total complication rate was 4.6%; as an expression of the learning curve it was reduced from 7.8% (operations 1 to 500) to 2.8% (operations 2,200 to 2,700). CONCLUSIONS: According to our experience, the TAPP technique is sufficiently applicable as a standard method for an unselected group of patients in a routine setting. It is especially suited to the repair of recurrent and bilateral hernias as well as for patients with a high risk for recurrence that can profit from a tension-free endoscopic procedure, particularly in case of obesity.
