[Minimally invasive operations in vascular surgery]. / Minimálne invazivní výkony v cévní chirurgii.

Minimally invasive surgery provides an attractive alternative compared with conventional surgical approaches and is popular with patients, particularly because of its favourable cosmetic results. Vascular surgery has taken its inspiration from general surgery and, over the past few years, has also been reducing the invasiveness of its operating methods. In addition to traditional laparoscopic techniques, we most frequently encounter the endovascular treatment of aneurysms of the thoracic and abdominal aorta and, most recently, robot-assisted surgery in the area of the abdominal aorta and pelvic arteries. Minimally invasive surgical interventions also have other advantages, including less operative trauma, a reduction in post-operative pain, shorter periods spent in the intensive care unit and overall hospitalization times, an earlier return to normal life and, finally, a reduction in total treatment costs.

Review and current update of robotic-assisted laparoscopic vascular surgery.

The field of vascular surgery is constantly evolving and is unsurpassed in its innovation and adoption of new technologies. Endovascular therapy has fundamentally changed the treatment paradigms for aneurysm and occlusive disease. As we continue to make advances in not only endovascular therapy, but also robotic surgery, artificial intelligence, and minimally invasive surgery, it is important that the vascular community stay at the forefront. Topics include the advantages of laparoscopic and robotic surgery over open surgery for aortic procedures, robotic versus laparoscopic aortic surgery, patient candidacy for robotic-assisted aortic surgery, and how to increase training and adoption of robotic-assisted laparoscopic aortic surgery. Future growth includes the development of new platforms and technologies, creation and validation of curriculum and virtual simulators, and conduction of randomized clinical trials to determine the best applications of robotics in vascular surgery.

The application of robotic surgery in vascular medicine.

OBJECTIVE: The feasibility of robotically assisted laparoscopic aortic surgery has already been adequately demonstrated. Our clinical experience with robot-assisted aortoiliac reconstruction for occlusive diseases, aneurysms, and hybrid procedures performed using the Da Vinci system is described below. METHODS: Between November 2005 and November 2011, we performed 225 robot-assisted laparoscopic aortoiliac procedures. One hundred seventy-four patients were prospectively evaluated for occlusive diseases, 43 patients for abdominal aortic aneurysm, two for common iliac artery aneurysm, two for splenic artery aneurysm, three for hybrid procedures, and one for endoleak II treatment after endovascular aneurysm repair. The robotic system was applied to construct the vascular anastomosis for thromboendarterectomy, for aortoiliac reconstruction with a closure patch, for dissection of the splenic artery, and for posterior peritoneal suturing. A combination of conventional laparoscopic surgeries and robotic surgeries was routinely included. A modified fully robotic approach without laparoscopic surgery was used in the last 55 cases in our series. RESULTS: Two hundred seventeen cases (96%) were successfully completed robotically; one patient's surgery was discontinued during laparoscopy because of heavy aortic calcification. In seven patients (3%), conversion was necessary. The 30-day mortality rate was 0.4%, and nonlethal postoperative complications were observed in 10 patients (4.4%). CONCLUSIONS: Our experience with robot-assisted laparoscopic surgery has demonstrated the feasibility of this technique for aortoiliac vascular and hybrid procedures. Compared with purely laparoscopic techniques, the Da Vinci robotic system facilitated the creation of the aortic anastomosis and shortened the aortic clamping time.

Robot-assisted aortoiliac reconstruction: A review of 30 cases.

OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
