Prophylactic retro rectus mesh cuts Incisional Hernia rate in midline laparotomy for abdominal aortic aneurysm

A new trial has revealed  that using prophylactic retro rectus mesh reinforcement can effectively reduce the rate of incisional hernias in midline laparotomy cases done for abdominal aortic aneurysms. The trial results were published in the journal Annals of Surgery. 

There is a high incidence of incisional hernias (IHs) after the open repair of an abdominal aortic aneurysm (AAA). Several trials in the past reported successful results with the use of prophylactic mesh to prevent IHs, without causing any complications. So, Maxime Dewulf et al reported the 5-year (60 months) follow-up results of the PRIMAAT trial. 

A prospective, multicenter, open-label, trial was carried out at eight Belgian hospitals. Patients with the planned elective treatment of an AAA through a midline laparotomy were considered eligible. Participants were randomized between prophylactic retro rectus mesh reinforcement (mesh group), and primary closure of their midline laparotomy after open AAA repair (no-mesh group). Ultrasonography or computed tomography was used for the diagnosis of IHs. The study's primary endpoint was the incidence of IHs 24 months after surgery.
