A week late

4、r, he was diagnosed with prostate (前列腺 ) cancer. “It was quite a month,“ says Forbes, a blunt Vietnam veteran who runs a consulting firm outside Boston. When biopsies confirmed he had an aggressive form of the disease, Forbes started looking for a surgeon. The first recommended a traditional radical

5、 prostatectomy (前列腺切除术 ), which would require an eight-to-10 inch incision and at 1east two days in the hospital Forbes was also warned that he would likely lose almost all the nerves on the left side of the prostate, which could permanently affect his sexual function. “I thought, I need to really l

6、ook at all my options ,“ says Forbes. He considered high-intensity focused ultrasound ablation (切除 ), a relatively new technology thats been used in Europe. But its expensive and would require transatlantic trips. He looked into various forms of radiation, as well as proton-beam therapy. Then, in Ju

7、ne, his girlfriend took him to a symposium on robotic surgery. “I saw the machine and how it worked,“ remembers Forbes. “It was just incredible. I said, Thats it.“ In August, Dr. Ashutosh Tewari, director of robotic prostatectomy at NewYork-Presbyterian Hospital/Well Cornell, removed Forbess walnut-

8、size prostate and lymph nodes and reattached his bladder to his urethra (尿道 )without once putting his hands inside the patient. Using Intuitive Surgicals da Vinci robotic system and operating through five tiny incisions, Tewari conducted the entire procedure from across the room. He sat at a console

9、 and turned two knobs to remotely manipulate tiny surgical instruments attached to adjustable robotic arms. Forbes was walking within hours of his surgery and was discharged the next day. He compares the discomfort from the largest incision (about two inches long, and the only one to require stitche

10、s) to a bad pimple. By midweek he was walking three miles daily. In 10 days he was back at work. After three weeks he was playing golf again; by late October hed regained normal urinary, and most sexual function. “Im about as excited as anyone can be about this procedure,“ he says. Using robots to p

11、erform surgery once seemed a futuristic fantasy. Not anymore. An estimated 36 600 robotic procedures will be performed this year- from heart-bypass surgeries to kidney transplants to hysterectomies (子宫切除术 ). Thats up nearly 50 percent from last year, and analysts predict the figure will nearly doubl

12、e in 2006 to more than 70 000 procedures. Since the da Vinci was approved by the Food and Drug Administration in July 2000 (the only robotic system to get the FDA nod), about 350 of the units have been purchased, including 30 in the last quarter alone, at about 1.3 million a piece. Surgeons who use

13、the system have found that patients have less blood loss and pain, lower risk of complications, shorter hospital stays and quicker recovery times than those who have open surgery. The robotic system has already transformed the field of prostate surgery, for which it was approved in May 2001. That ye

14、ar it was used in less than 1 percent of all prostatectomies. This year more than 20 percent will be done with the robot. And that figure is expected to double next year. “Its becoming the standard of care for prostatectomies,“ says Dr. Santiago Horgan, director of minimally invasive and robotic sur

15、gery at the University of Illinois at Chicago (UIC). The first major study to compare open and robotic prostatectomies was published in the British Journal of Urology in 2003 by Dr. Mani Menon, head of the Vattikuti Urology Institute at Detroits Henry Ford Hospital. (The hospital has now done about

16、2 050 of the robotic procedures -more than any other in the nation. ) The study of 300 patients found that those who had open surgery lost five times as much blood, had four times the risk of complications and remained in the hospital more than three times as long as those who had robotic surgery. R

17、obotic-surgery patients had a 14 percent higher rate of cancer removal and, on average, regained urinary function in about a month and a half- four times as fast as open-surgery patients. Also, robotic patients were able to have sexual intercourse again in about 11 months, while half of the open-sur

18、gery patients had not regained full sexual function even two years later. The response to the findings was skeptical at best. “They didnt believe any of it,“ Menon says of some peers. “It just seemed too good to be true.“ But a year later, Dr. Thomas Ahlering, chief of urological oncology at the Uni

19、versity of California, Irvine, Medical Center, published similar findings in the journal of Urology using 120 of his own patients. And the tide began to turn. “Dr. Menon and a few others showed excellent results with the da Vinci, and then they showed that their results are reproducible,“ says Dr. R

20、eza Ghavamian, director of urologic ontology at New Yorks Montefiore Medical Center, which purchased a system this fall. “Theres no question this system has revolutionized the surgery.“ Five years ago, says Dr. David B. Samadi, director of robotic laparoscopic urology surgery at NewYork-Presbyterian

21、 Hospital/Columbia Medical Center, 80 to 90 percent of the prostatectomies he did were open, with less than 10 percent done robotically. Now the figures have reversed. “There is much less blood loss and an extremely low rate of complications,“ he says. Forbess procedure required just five small cuts

22、. A surgical assistant inserted a tiny camera and different instruments, all attached to robotic arms, into Forbess body through pen-size holes. As he remotely manipulated the forceps or scissors, Tewari kept his eyes glued to a 3-D monitor, which showed images captured by the camera and magnified 1

23、0 times. “I can see things now within a fraction of a millimeter,“ says Tewari, who has done nearly 300 robotic prostatectomies in the past year. The next frontier for robotic surgery may be gynecologica (妇产科学的 ) laparoscopic procedures, for which the system was just approved this spring. There are

24、about five times as many hysterectomies as prostateetomies performed each year, and surgeons say the complex procedure could benefit from the robotic systems precision. Cardiac surgeons have also begun using the da Vinci for a range of procedures, from mitral-valve repair to coronary-bypass surgery.

25、 In October, Dr. Francis Sutter, chief of cardiology at the Heart Center at Lankenau Hospital, near Philadelphia, did what he says is the first da Vinci double bypass. “Id heard these stories about how they cut you right down the middle,“ says his patient Gilbert Minacci, a 65-year-old retired schoo

26、l principal from Glen Rock, Pa. But he had just a single two-inch incision on the left side of his chest. A week and a half after the surgery, Minacci was walking 30 minutes a day, and tests show his heart function is normal again. “I think even my doctor was surprised that I bounced back so quickly

27、,“ he says. “If you have to go through this, I dont think it could have been much better.“ While Sutter is a proponent of the system, he says his peers may be put off by the price tag. His center held fund-raisers to help pay for the da Vinci system in April. “Obviously, I am sold on it,“ says Sutte

28、r, who has since performed 30 coronary bypasses with the system. “But these robots cost a lot of money. Thats been a barrier.“ Insurance companies usually pay the same amount regardless of the type of procedure a patient picks, Sutter says, so the hospital is left picking up the tab for the more exp

29、ensive robotic surgery. Also, some surgeons are reluctant to commit the hours necessary to learn robotic techniques. “There are a lot of surgeons who do what they do, and do it well, and dont want to spend time learning a new skill set,“ says Scott Goldman, surgery chairman of Main Line Health, whic

30、h owns the Heart Center at Lankenau. “But I think the people with the strongest objections have never tried it.“ 2 High-intensity focused ultrasound ablation (切除 ) is a relatively new technology which is expensive and but only operated in Europe. （ A） Y （ B） N （ C） NG 3 Half a year after his 60th bi
