Aneurysma Hernia Study - Incidence of Incisional Hernias After Abdominal Aortic Aneurysm Repair

"Principles technique for closure of midline laparotomy incisions~* closure with a running suture of a slowly absorbable monofilament suture- Monomax 2/0 of 150 cm length with a taper needle point ((1/2 circle, size: 30mm) (B.Braun, reference 0041453)~* the suture is started and ended with a self-locking knot, if more than one suture is used sutures are knotted separately, only the fascia will be sutured with small stitches close to each other~* the SL/WL ratio should be at least 4/1~* SL/WL = (150cm x number of sutures used) - (the suture remnants)~* the mean stitch length should be less than 4 cm (suture length / number of stitches placed)"

the fascia will be closed with the current method by the surgeons. There will be a great variation in sutures and techniques used. Study group: the fascia will be closed according
