Background: Laparoscopically assisted aortic aneurysm resection requiring a minilaparotomy can be performed as a routine procedure. It was the purpose of our study to evaluate whether a total laparoscopic operation can be offered to aneurysm patients as a minimally invasive alternative. We also wanted to test whether a master-slave robot could facilitate the total laparoscopic procedure. Methods: A prospective, consecutive number of 50 patients was evaluated. A transperitoneal left retrocolic access was used to expose the aorta. If possible, a tube graft repair was performed. The aortic anastomosis was sutured totally laparoscopically, with the surgeon standing on the right side of the operating table. In 10 consecutive patients, the anastomosis was sutured with the help of the Zeus robot. Results. After excluding 3 cases that required suprarenal cross-clamping, 47 patients were operated using a total laparoscopic approach. A totally laparoscopic operation could be performed successfully in 39 patients with aneurysms. In 8 patients (17%), conversion to a laparoscopic hand-assisted operation with a 7-cm minilaparotomy was required. The robot was used to perform the aortic anastomosis in 10 patients. In 8 patients, a tube graft repair could successfully be performed totally laparoscopically. In the remaining patients, a bifurcated graft was implanted laparoscopically. The mean operating time was 227 minutes in the laparoscopy group and was 242 minutes in those patients in whom the anastomosis was sutured with the help of the Zeus Robot. Mean cross-clamping time, +/- SD, was 81.4 + 31 minutes. None of the patients died perioperatively. Major complications occurred in three patients (6.3%). The overall morbidity was 14.8%, including one patient who required temporary hemodialysis postoperatively. The time to suture the aortic anastomosis was significantly shorter in the robotic-assistance group (40.8 +/- 4 minutes), yet total operating time was longer in this group because of the technical complexity of the robotic device. Patients with a total laparoscopic procedure asked for significantly fewer analgesics and could regain full mobility earlier compared with those patients for whom a minilaparotomy after conversion to the laparoscopic hand-assist procedure was required. Conclusions: 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.
