Laparoscopic surgery for abdominal aortic aneurysms - Technical elements of the procedure and a preliminary report of the first 22 patients

Background: Laparoscopic surgery for infrarenal aortic aneurysms is based on the principle of retroperitoneal exclusion of the aneurysm sac with aortofemoral or aortoiliac bypass. Methods: Of 22 patients who met the selection criteria, 20 successfully underwent laparoscopic aortic surgery at Morristown Memorial Hospital between February and October 1997. Technical elements and steps of this operation are described and illustrated. Results: Within 30 days of surgery, 2 patients died and 9 had various major and minor perioperative complications. As a group, the laparoscopic patients had less postoperative pain, needed fewer hours of ventilator support, had shorter intensive care unit (ICU) and hospital lengths of stay, and resumed diet and normal activity earlier than the historical norms for patients undergoing transabdominal or retroperitoneal aortic resections at the same institution. Conclusions: These early observations suggest that the laparoscopic treatment of infrarenal abdominal aneurysms may have several significant potential benefits. Long-term results and randomized prospective studies with patients matched by risk stratification will be needed to confirm these impressions.
