Incidence and risk factors for incisional hernia after abdominal aortic aneurysm and aortic occlusive disease surgery

Abstract

Background: This study aims to investigate incisional hernia incidence and risk factors after abdominal aortic aneurysm and aortic occlusive disease surgery via a midline laparotomy. Methods: A total of 110 patients (66 males, 44 females; mean age: 69.3±8.8 years; range, 36 to 88 years) who underwent open elective surgery for aortoiliac occlusive diseases or abdominal aortic aneurysm between January 2005 and December 2016 were retrospectively analyzed. Both patient groups were compared in terms of surgical procedures, sex, age, American Society of Anesthesiologists score (1-3), body mass index (<25 vs. ≥25 kg/m2 ), smoking (non-smoker <1 pack/day, smoking ≥1 pack/day), and time to incisional hernia development. Results: Incisional hernia occurred in 14.3% of the patients operated for aortoiliac occlusive disease and in 17.6% of the patients operated for abdominal aortic aneurysm (p=0.643). Incisional hernia was seen in three (5.7%) of 53 patients with a body mass index of <25 kg/m2 and was in 15 (26.3%) of 57 patients with a body mass index of ≥25 kg/m (p=0.03). Conclusion: High body mass index is a risk factor for incisional hernia in patients undergoing aortic reconstructive surgery.
