Preliminary experience with minilaparotomy aortic surgery

This prospective nonrandomized study assessed clinical outcomes of a minilaparotomy technique (MLT) used for elective graft repair of infrarenal aortic aneurysm (AAA) and/or aortoiliac occlusive disease (AIOD). Twenty-three patients requiring infrarenal AAA or aortofemoral bypass underwent a small periumbilical midline incision, nondisplacement of the small bowel, and a traditional vascular anastomosis. Results from these procedures were compared with those from contemporaneous procedures performed in the standard transabdominal (STA) fashion (n = 21). Age, weight, and comorbid conditions were comparable between groups. Patients requiring concomitant renal, mesenteric, or infrainguinal revascularization were excluded. Operating time, length of stay in the intensive care unit (ICU), number of oral feeding times, and length of hospital stay were recorded. There were no significant differences in age, operative time, or aneurysm size between the MLT and STA groups. With the MLT then were significant decreases in ICU stay (1 vs. 1.8 days), length of time to return to a general diet (3 vs. 4.7 days), and length of stay (4.9 vs. 7.3 days.) Morbidity and mortality were not statistically different between groups. Patients undergoing the MLT have reduced ICU and hospital stay, and decreased post operative ileus. The MLT does not increase operating room costs or require expensive laparoscopic equipment or the extended postoperative radiographic surveillance needed after endovascular repair.
