The Harald Breivik lecture 2022. Pathophysiology in persistent severe pain after groin hernia repair

Abstract

The transition from a healthy to a persistent severe pain state following otherwise successful elective surgery is a feared complication. Groin hernia repair, previously considered minor surgery, is a standard surgical procedure annually performed on 2,000 individuals per one million residents. A trajectory into persistent severe pain is, unfortunately, seen in 2-4%, severely impeding physical and psychosocial daily functions.
