NCT00627289

Brief Summary

Chronic postherniotomy pain affects every day activities in 5-8% of patients. However, no established treatment for this pain syndrome exists and previous reports on the effect of surgical intervention suffer from methodological problems. The neurophysiological characteristics suggest that pain arises from deeper neuronal structures injured during surgery or by ongoing inflammation from the mesh. This study investigates the effect of removing inserted mesh and compressed nerves on pain related daily impairment of activities assessed by the validated AAS questionnaire before and 6 months after surgery

Study Population

Patients with chronic pain occuring after groin hernia repair. Patients must experience moderate/severe pain related impairment of everyday activities. Patients have to be able to localize a maximum point of pain.

You may qualify if:

  • Adult ( more than 18 years old) patients with chronic pain after groin hernia surgery, and pain related impairment of everyday function. The pain should have occurred after previous open surgery.
  • The patient should be able to locate to a specific area with maximum pain. Patients should be able to understand and use pain scales, and the AAS-scale.

You may not qualify if:

  • All that contradicts the above
