Meta-analysis of postoperative pain using non-sutured or sutured single-layer open mesh repair for inguinal hernia: Pain after non-sutured versus sutured open mesh repair for inguinal hernia

Background Chronic postoperative pain occurs in up to 21·7 per cent of patients undergoing open inguinal hernia repair. Several mesh fixation techniques using glue or self‐gripping meshes have been developed to reduce postoperative pain. The aim of this meta‐analysis was to evaluate RCTs comparing adhesional/self‐gripping and sutured single‐layer open mesh fixations in the repair of inguinal herniation, with postoperative pain as endpoint.
