Anesthetic implications of the addition of an operative robot for endoscopic surgery: a case report.

Laparoscopic surgery has become increasingly popular over the last decade. However, this surgical technique has a number of limitations. It is difficult to work in a three-dimensional space while viewing a two-dimensional monitor, long instruments amplify natural tremor, and traditional instruments have limited mobility due to few degrees of freedom. Robot-assisted surgery has been developed in response to these limitations. A three-dimensional viewer allows the surgeon to operate in a realistic environment, natural tremor is eliminated by translating the surgeon's hand motions to robotic movements, and the robotic surgical instruments are designed to have the same dexterity as a human wrist. We describe a case of robot-assisted laparoscopic Nissen fundoplication and discuss the anesthetic issues associated with this new surgical technique. In addition to the anesthetic issues associated with traditional laparoscopic surgery, robot-assisted laparoscopic surgery presents some unique challenges.

Robotic surgery: is it for you?

Robotic surgery has indeed arrived. The approved device in the United States, the Intuitive Surgical System's daVinci System, is installed in about 80 hospitals worldwide. That number is rising rapidly. Once other companies, Computer Motion for example, receive Food and Drug Administration approval for their systems, the number of robotic-equipped operating rooms will begin to increase enormously. The current outcry regarding the expense of these systems is certainly not without merit. However, I would urge surgeons interested or even just curious about these systems to try one in a laboratory setting. The ease of accomplishing difficult tasks and the vividness of the 3-dimensional imaging create an experience that is both extremely impressive and enjoyable. There are currently no data to justify the expense of these systems in terms of patient outcomes or reduced complications. Such data will take a great deal of time and effort to accumulate. However, having become accustomed to the robotic system, this surgeon would have difficult moving back to standard laparoscopic instrumentation. Imagine during a standard open operation that your scrub assistant rubbed grease on your glasses and took away your favorite forceps and needle holder and gave you clumsy instruments 18 inches too long with less-than-reliable action at the tips. With enough struggling you would be able to accomplish the operation, and perhaps over time, even become facile with subpar instruments. However, you would certainly rather see well and have the instruments that you know work best in your hands. It would be very difficult to design a study to prove that your patients are better off when you use your normal instruments and clean glasses as opposed to fogging glasses and difficult-to-use instruments. But, you would know that there is a difference. That in large part is the feeling of surgeons who have had the good fortune of becoming accustomed to the current robotic systems for minimally invasive surgery. They can see much better and can manipulate tissue much better. Most of them are also convinced that when they can see better and manipulate tissue better, the outcomes for their patients are better. Is robotic surgery right for you? The answer is complex and has a myriad of elements. This author would suggest that a great start in determining the answer would be to try the current systems and keep track of both the literature and the technical evolution regarding these systems as time progresses.

Median arcuate ligament syndrome: evaluation with CT angiography.

The median arcuate ligament is a fibrous arch that unites the diaphragmatic crura on either side of the aortic hiatus. The ligament usually passes superior to the origin of the celiac axis. However, in some people, the ligament inserts low and thus crosses the proximal portion of the celiac axis, causing compression and sometimes resulting in abdominal pain. The diagnosis of clinically significant celiac axis compression, referred to as median arcuate ligament syndrome, is traditionally made with conventional angiography; however, the condition can now be diagnosed with three-dimensional computed tomographic (CT) angiography. In patients with median arcuate ligament syndrome, CT angiograms demonstrate a characteristic focal narrowing in the proximal celiac axis. The focal narrowing has a characteristic hooked appearance, which can help distinguish this condition from other causes of celiac artery narrowing, such as atherosclerotic disease. Once the disorder has been diagnosed, surgery can be performed to relieve the compression. In some patients, the ligamentous constriction of the celiac axis causes vascular damage, which may require vascular reconstruction. CT angiography can play a role in the diagnosis of median arcuate ligament syndrome by demonstrating the characteristic focal narrowing of the celiac artery in patients presenting with the appropriate clinical symptoms.
