First Hungarian, internet-based prospective, multicenter study: the hernia-project.

In inguinal hernia repair, different laparoscopic and open techniques of tension-free repair using synthetic meshes have been reported to result in better patient comfort and lower recurrence rates compared with conventional procedures like Shouldice's or Bassini's operation. In comparison with the laparoscopic procedure, open tension-free repair can be performed under local anaesthesia and is less expensive. For these reasons, the recent trend in inguinal hernia surgery, has been towards using an open, mesh-based tensionless repair (Lichtenstein technique). To evaluate and support the widespread use of this technique in Hungary a large, prospective multicentre trial was initiated at 15 March 1999. Prospective registration of 1500 hernia operation using Lichtenstein technique is undertaken that is carried out in 15 hospitals. Postoperative outcome, complications and recurrence is recorded through a five years period. The case presentation and data collection is internet based. Each center participating in the study is connected by internet to the coordinating center and all information concerning this study is sent by this way. This system is able to generate actual statistical data in every moment of the study.
