title: A single institution's experience with transperitoneal laparoscopic hernia repair.
abstract: 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.
