Comparing mesh removal to no mesh removal for chronic groin pain after hernia repair

Mesh Removal Versus No Mesh Removal for Chronic Groin Pain After Minimally Invasive Inguinal Hernia Repair: A Randomized Controlled Trial

Not applicable Interventional The Cleveland Clinic · NCT05484635

This study is testing whether taking out hernia mesh helps people with chronic groin pain feel better compared to not removing the mesh after their hernia repair.

What this trial studies

This study evaluates the management of chronic groin pain following minimally invasive inguinal hernia repair, specifically assessing the effects of hernia mesh removal versus no removal. It is a double-blinded, randomized-controlled trial where participants may undergo diagnostic laparoscopy and could potentially have their mesh removed if they do not achieve adequate pain relief. Patients will be informed about the trial and can withdraw at any time. The study aims to determine if mesh removal leads to significant pain relief in patients suffering from chronic pain lasting more than six months.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with chronic nociceptive groin pain lasting more than six months after inguinal hernia repair.

Not a fit: Patients who do not exhibit characteristics of nociceptive groin pain or have mild pain may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide effective pain relief options for patients suffering from chronic groin pain after hernia repair.

How similar studies have performed: Other studies have explored similar interventions, but the specific approach of mesh removal for chronic pain in this context is relatively novel.
