Total laparoscopic aneurysm resection can be offered to the majority of patients in our institution. The robot still requires further refinements to reduce operating times and the aortic cross-clamping period. We now have the technique and the instrumentation to offer laparoscopic aneurysm surgery as a minimally invasive alternative for patients whose conditions are unsuitable for endovascular aneurysm repair.

The sandwich technique is an off-the-shelf endovascular alternative to treat patients with TAAAs in an emergent setting. The combination of chimney grafts with a periscope configuration enables a rapid endovascular aneurysm exclusion with acceptable midterm results.

In the following paper we describe our experience with a large number of patients in which either a laparoscopic assisted procedure or a total laparoscopic operation was performed. From 1996 until 2005 a total number of 638 aortic patients were operated on using a total laparoscopic or a laparoscopic assisted approach. A total laparoscopic operation was accomplished in 236 cases. A laparoscopic assisted aortic operation was performed in 402 patients. In aneurysm patients a tube graft was more frequently implanted. Thirty-day mortality was significantly higher in patients with a total laparoscopic abdominal aortic aneurysm repair (3.0%) compared to a laparoscopic assisted procedure (1.8%). There was no significant difference in mortality in patients with occlusive disease and a total laparoscopic aortofemoral bypass versus a laparoscopically assisted operation. The same tendency could be observed when analyzing the incidence of major perioperative complications. Again we found no significant difference in patients with occlusive disease yet more severe complications directly related to the operation in patients with a total laparoscopic aneurysm repair. There was a significantly increased complication rate in total laparoscopic aortoiliac repair with a bifurcated prosthesis compared to a tube graft repair: a tendency we could not observe in aneurysm patients with a laparoscopic assisted operation. Our data also show that there is a lot of room for technical improvements such as stapling devices or special grafts to reduce total operating times as well as the period of aortic crossclamping. The routine use of a minilaparotomy can hardly be a solution considering the technical drawbacks such as impaired vision and long term complications like ventral hernias. Compared to open surgery the midterm results of laparoscopic aortic procedures are promising. The time has come to prove that good results can be obtained in more than a few specialized centers.
