Flemish Inguinal and Femoral Hernia Prospective Registry

Prospective registry. The purpose of this clinical trial will be to measure surgical outcome parameters (e.g. recurrence, chronic pain and other quality indicators) after inguinal hernia repair using Patient Reported Outcome Measures (PROMs) in the short- and long-term.

The primary objective is to investigate moderate to severe chronic pain 1 year after inguinal or femoral hernia repair, defined as numeric rating scale (NRS) ≥ 4, during daily activities. The secondary objectives are: * Surgical Site Occurrence (SSO) after 30 days * Scope and incidence of pre- and postoperative pain (NRS 0 to 10) * The difference between pre- and postoperative NRS scores (relative NRS score) * Presence of pain and impact of pain on daily life activities * Satisfaction and quality of life * Sexual function * Anxiety and depression * Catastrophizing * Recurrence * Development of a predictive model for chronic pain.
