Prostate Cancer Probe to Ease Impotence Opposed by Panel
July 31, 2014
EDAP TMS SA (EDAP), the maker of an ultrasound device to treat prostate cancer with lower rates of erectile dysfunction, lost almost half its market value after the product failed to win a U.S. advisory panel’s backing.
EDAP didn’t provide evidence the device is safe and effective, advisers to the Food and Drug Administration voted yesterday. The device, called Ablatherm, is an alternative to traditional surgical and radiation treatments. It uses a robotic arm to insert a high-intensity, focused ultrasound device that kills cancer cells.
While the company, based in Vaulx-en-Velin, France, said Ablatherm produces lower rates of side effects than traditional treatments, an FDA staff report released July 28 questioned whether EDAP’s methods for testing are adequate.
“I’m somewhat troubled by the statistical data,” said Peter Lewin, a panel member and biomedical engineering professor at Drexel University. “My reading of the tea leaves was that it was inconclusive and inadequate. A wonderful technology that is coming out is getting a bad rap because of badly designed statistics,’’ he added.....read more
Ablatherm is a probe connected to a robotic arm that is inserted through the rectum. A urologist watches an ultrasound of the patient’s prostate, and the probe heats the tissue and kills cancer cells. The device can be used as an outpatient procedure, and it would be the first such product in the U.S. approved for the treatment of prostate cancer, said Marc Oczachowski, Chief Executive Officer of EDAP.

10-Year Success With Robotic Prostate Surgery
July 28, 2014
New Study Documents the Long-Term Success of Robotic-Assisted Surgery With Effective Prostate Cancer Control for 10 Years, Says Robotic Prostate Surgeon, David B. Samadi, MD
Robotic prostate removal surgery is a preferred treatment method for men with localized prostate cancer. According to a new study from Detroit, Michigan, robotic prostatectomy yields highly successful long-term prostate cancer results. In fact, nearly all -- 98.8% -- of the patients remained prostate cancer survivors at ten years post-surgery; results comparable to the more invasive surgical method used in the past.
The study also highlighted the importance of personalized patient care following robotic prostate surgery. Combining modern molecular diagnostic techniques with traditional post-surgery tumor analysis and prostate-specific antigen (PSA) testing can enhance the ability to predict recurrence and design appropriate follow-up regimens. One of the leading robotic prostate surgeons, David B. Samadi, MD, Chairman of Urology and Chief of Robotic Surgery at Lenox Hill Hospital, emphasizes a personalized approach to long-term patient monitoring......read more

Gill performs first robotic-assisted operation in California with new system
July 21, 2014
Keck Medical Center of USC urologic surgeon Inderbir Gill has performed the first robotic-assisted procedure in California using the latest, minimally invasive surgical system.
The procedure used the new da Vinci Xi Surgical System that gives surgeons greater dexterity, precision and ability to remove cancerous tissue in all quadrants of the abdomen and chest because of its smaller arms. In addition, surgeons have a larger operating field in which to work, leading to better maneuverability without having to reposition the robot as frequently throughout the procedure.
The da Vinci Xi Surgical System robot created by Intuitive Surgical was approved by the Food and Drug Administration on April 1. Using the Xi robot, Gill, founding executive director of the USC Institute of Urology and professor and chairman of the Department of Urology, removed a man’s prostate......read more
Surgeons of the University Hospital Essen Complete World's First Robotic-Assisted Cancer Surgery with Medrobotics' Flex® System
July 21, 2014
ESSEN, Germany — Leading surgeons of the Ear, Nose and Throat Clinic at the University Hospital Essen completed the world’s first robotic-assisted cancer procedures with the Medrobotics’ Flex® System. Professor Stephan Lang PD, Dr. Urban Geisthoff and Dr. Pia Haßkamp successfully performed the removal of a malignant lesion in one patient and the removal of a benign lesion in a second patient.
These patients are also the first two enrollees in a multi-center post-market clinical follow-up study in Germany and Belgium, which will prospectively treat up to 80 subjects who are candidates for oropharyngeal or hypopharyngeal transoral surgery. The study is designed to assess the safety and performance of the Medrobotics Flex® System for access and visualization of structures in the mouth and throat down to the level of the voice-box.
The Flex® System, designed and manufactured by Medrobotics Corporation, enables surgical procedures where conventional line-of-sight technologies are either not feasible or sub-optimal. Surgeons can navigate the Flex® System around anatomical structures to hard-to-reach locations through a single access site, and then use the onboard high-definition vision system to precisely deploy flexible surgical instruments. The uniquely “wristed” 3mm Flex® Instruments enable the surgeon to operate in confined spaces, further extending his or her reach to important and often challenging areas of the anatomy......continue reading
New Components That Turn from Soft to Rigid May Revolutionize Robotic Surgery
July 21, 2014
Robotic assisted surgery these days involves rigid instruments that often have to operate in difficult to access parts of the body. This is a major limiting factor that still necessitates open surgery when access to the treatment site is challenging. Researchers at MIT, Max Planck Institute for Dynamics and Self-Organization, and Stony Brook University are now developing “squishy” robotic components that can squeeze through narrow passages and pop right back to their original shape.
The components are made out of a composite material consisting of open-cell foam that was coated with wax. In its room temperature state, the material is stiff, but by applying heat, the wax softens and makes the material pliable. The team envisions wires running through the material that can be quickly heated by running an electric current through them, resulting in a material that can be made soft or hard at the press of a button. Moreover, the material is self-healing, so that when cracks appear due to stress when the material is in its rigid state, it can then be heated and cooled back down to repair any damage.

Cognitive assessment provides window into proficiency level of robot-assisted surgeons
July 9, 2014
What clues might brain metrics hold about the skill levels of surgeons who perform robot-assisted surgeries? Looking for better ways to assess the proficiency of surgeons performing these complex procedures, researchers at Roswell Park Cancer Institute (RPCI) and the University at Buffalo (UB) determined whether cognitive assessment can effectively measure the expertise of robotic surgeons with varying levels of experience. They found that assessment of robotic surgeons' cognitive processes during surgery gives a fuller, more reliable picture than other measurable indicators, and may be a valuable element to incorporate into robotic surgery training.
The study, published online ahead of print in the journal BJUI, is the first published report to evaluate surgeons' cognition during robot-assisted surgery......continue reading
The benefits of robotic kidney cancer surgery
The benefits of robotic kidney cancer surgery
July 7, 2014
Robotic-assisted surgery is increasing in popularity in many surgical areas including kidney cancer surgery. Researchers from UCLA’s Jonsson Comprehensive Cancer Center led the largest multicenter study to date on a surgical procedure known as a retroperitoneoscopic robot-assisted technique for removal of small kidney cancers. They published their findings online on July 7 in the journal European Urology.
The study authors note that approximately 50,000 Americans are diagnosed with kidney cancer each year. The majority of these malignancies are small tumors that are often found during screening for other medical problems. These tumors require surgical removal; however, the surgery is often technically difficult, especially if they are located on the posterior (rear) side of the kidney. Another surgical challenge that occurs is among patients who have had previous abdominal surgery; these patients may have scar tissue that hampers the identification of normal anatomy.
Study leader Dr. Jim Hu and his colleagues at UCLA’s Jonsson Comprehensive Cancer Center have shown that robot-assisted retroperitoneoscopic partial nephrectomy (RARPN) is an ideal approach for patients with posterior kidney tumors or previous abdominal surgery. RARPN is a type of minimally invasive laparoscopic surgery in which the operation is performed with precise robotic arms and magnified, high-definition 3-D cameras that are controlled by the surgeon. The five-year study comprised 227 patients who were an average age of 60 years.......read more
Early Adoption Robotic Prostatectomy Associated With Patient Harm?
July 4, 2014
During the early adoption phase of robotic prostatectomy, there was a 2-fold increase in adverse events with this technique compared with traditional open radical prostatectomy (ORP) for prostate cancer, a new analysis has found.
The study, published online July 2 in JAMA Surgery, shows that the rapid introduction of a new surgical technology can result in patient harm, say the authors.
"The current system in the United States by which surgical innovations are introduced into community practice is flawed in that there are no standardized procedures to ensure their safe adoption," lead author J. Kellogg Parsons, MD, MHS, a urologic oncologist at the University of California, San Diego School of Medicine, told Medscape Medical News.
However, an accompanying commentary questions the conclusions and points out that there was a significant difference between adverse events reported with the 2 surgical techniques only for 1 year, the year prior to the "tipping point." For the other years, the risk of adverse events was similar, suggesting that the new technique of robotic prostatectomy was comparable with open surgery even during its early adoption.......Log in to Medscape for more

Testosterone Therapy Does Not Cause Prostate Cancer
July 3, 2014
Good News for Men With Low T: Long-Term Testosterone Therapy Does Not Increase Prostate Cancer Risk, Says Robotic Prostate Surgeon, David B. Samadi, MD
What are the dangers of testosterone therapy? Does long-term hormone replacement therapy increase prostate cancer risk? Testosterone replacement therapy is on the rise, though recent reports suggest that low testosterone (Low T) diagnoses may be too prevalent and that excessive treatment pose risks to men. However, according to a recent German study, long-term testosterone therapy does not increase a man's risk of developing prostate cancer.
Some experts caution that testosterone therapy is overused. Evidence shows that the treatment increases prostate size, elevates prostate-specific antigen (PSA) levels, and permanently impairs the body's ability to produce natural testosterone. Leading New York robotic prostate surgeon, David B. Samadi, MD, Chairman of Urology and Chief of Robotic Surgery at Lenox Hill Hospital, encourages men to seek a second opinion before beginning a testosterone therapy regimen.
"For some men, Low T is very real and can cause loss of energy, reduced sex drive, weight gain, and depression," said Dr. Samadi. "Men with truly low testosterone levels can experience tremendous benefits from testosterone therapy and may opt for long-term treatment. For them, this is good news. Their risk of prostate cancer is no higher than that of other men."
German researchers conducted registry studies......read more
