Robot-assisted aortoiliac reconstruction: a review of 30 cases

Abstract

The feasibility of laparoscopic aortic surgery with robotic assistance has been sufficiently demonstrated. Reported is the clinical experience of robot-assisted aortoiliac reconstruction for occlusive disease and aneurysm performed using the da Vinci system. Between November 2005 and June 2006, 30 robot-assisted laparoscopic aortoiliac procedures were performed. Twenty-seven patients were prospectively evaluated for occlusive disease, two patients for abdominal aortic aneurysm, and one for common iliac artery aneurysm. Dissections of the aorta and iliac arteries were performed laparoscopically using a transperitoneal direct approach technique, a modification of the Stádler method. The robotic system was used to construct anastomoses, to perform thromboendarterectomies and, in most of the cases, for posterior peritoneal suturing. Robot-assisted procedures were successfully performed in all patients. The robot was used to perform both the abdominal aortic and common iliac artery aneurysm anastomoses, the aortoiliac reconstruction with patch, and to complete the central, end-to-side anastomosis in another operation. Median operating time was 236 minutes (range, 180 to 360 minutes), with a median clamp time of 54 minutes (range, 40 to 120 minutes). Operative time is defined as the time elapsed from the initial incision to final skin closure. Median anastomosis time was 27 minutes (range, 20 to 60 minutes), and median blood loss was 320 mL (range, 100 to 1500 mL). No conversion was necessary, 30-day survival was 100%, median intensive care unit stay was 1.8 days, and median hospital stay was 5.3 days. A regular oral diet was resumed after a mean time of 2.5 days. Robot-assisted laparoscopic surgery is a feasible technique for aortoiliac surgery. The da Vinci robotic system facilitated the creation of the aortic anastomosis and shortened aortic clamp time in comparison with our laparoscopic techniques.
