Hernia repair one of the most frequently performed operations in general surgery. With the introduction of tension-free mesh repair, recurrence rates dropped well below 5% for open and laparoscopic procedures. However, chronic postoperative pain remains a widely neglected complication with a high socio-economic impact. It occurs in about 10-20% of patients after hernia repair. We review the different types of post-herniorrhaphy pain with the typical diagnostic features and we conclude with a pragmatic algorithm based on our clinical experience.
