Brief Summary:
Chronic pain may be a long-term problem after inguinal Lichtenstein hernioplasty. The aim of this study was to compare long-term results of hernioplasty using three different meshes (partly absorbable, lightweight polypropylene and thick polypropylene mesh).

Condition or disease Intervention/treatment Phase
Chronic Pain Recurrences Device: Vypro II mesh Device: Premilene LP Device: Premilene mesh Not Applicable

Detailed Description:
Inguinal hernioplasty was performed under local anesthesia in 300 patients in day-case surgery by the same surgeon and exactly by the same surgical technique. The patients were randomized to receive either a partly polypropylene-polyglactin mesh (Vypro II, 100 hernias), a lightweight polypropylene mesh (Premilene LP, 100 hernias) or a conventional densely woven polypropylene mesh (Premilene, 100 hernias). Pain, patients discomfort and recurrences of hernias were carefully followed 5 years after surgery.

Primary Outcome Measures :
  1. Presence of chronic pain [ Time Frame: 5 years ]
    Pain scores were measured by using a visual analoque scale.

Secondary Outcome Measures :
  1. Presence of recurrences [ Time Frame: 5 years ]
    Recurrence of inguinal hernias after Lichtenstein hernioplasty was studies during clinical and ultrasound examination
