Robotic prostate removal tied to surgical changes, costs
August 26, 2014
The introduction of robotic surgery for prostate cancer may have led to changes in the number of surgeons performing prostate removals and in the overall cost, according to a new study.
With the technology being used more widely, fewer doctors are performing the procedure and the overall cost of prostate removal has gone up, researchers found.
While studies examining the benefits and potential harms of robotic surgery have produced mixed results, the researchers write in BJU International that there is little information on how the innovation influenced prostate removal in the U.S.
Robotic-assisted radical prostatectomy, which is the removal of the prostate with the help of a robot, began after U.S. regulators approved Intuitive Surgical, Inc.’s da Vinci Surgical System in 2000.
Before that, surgeons would remove the prostate through a relatively large incision in so-called open surgery - or through a small incision with the help of a camera, in laparoscopic surgery.
For the new study, the researchers used data on nearly 490,000 men who had their prostates removed between 2003 and 2010. Of those, 338,448 had open or laparoscopic surgery and 150,921 had robotic-assisted surgery.......read more
Keck Medical Center of USC becomes only worldwide training center for Da Vinci Xi robotic-assisted thoracic surgery
Posted on AARS: August 25, 2014
Surgeons at the Keck Medical Center of the University of Southern California (USC) this summer became the first in Southern California and among the first west of the Mississippi to perform the Food and Drug Administration (FDA)-approved robotic-assisted procedure for a lung cancer patient using the latest, minimally invasive surgical system, the da Vinci Xi robot. In addition, USC chief of thoracic surgery, Jeffrey A. Hagen, MD, and Keck Medicine of USC thoracic surgeon, Daniel S. Oh, MD, will head the only worldwide training center located at Keck Medical Center of USC for other surgeons to learn how to use the Xi robotic system for thoracic procedures.
The new da Vinci Xi Surgical System robot created by Intuitive Surgical was approved by the Food and Drug Administration on April 1. The first FDA-approved thoracic surgical procedures were performed this summer, among them cases by Hagen and Oh. The new Xi robot is optimized for thoracic procedures. The robotic system 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 Keck Medical Center of USC, which consists of Keck Hospital of USC and USC Norris Cancer Hospital, has been pioneering robotic surgery for years and is the fastest-growing robotic surgery center in the country.
KidsArm Pediatric Surgical Robot Inspired By Space Station Technology
August 21, 2014
KidsArm, was designed by the same companies that developed the robotic arms used to build the International Space Station (ISS). KidsArm allows surgeons to quickly navigate to surgical sites within the body with an advanced imaging and control system that makes it extremely precise. The robot was also designed to explore the idea of automating certain demanding tasks in minimally invasive pediatric surgery, which has been challenging for doctors.
“Our tests indicate we can operate on tiny structures such as blood vessels without damaging them,” Thomas Looi, the project director at the Hospital for Sick Children Centre (SickKids) for Image-Guided Innovation & Therapeutic Intervention in Toronto, Canada, said in a NASA statement on Wednesday.
“The goal of the robotic arm is to help doctors perform certain procedures many times faster than if they were only using their hands and with increased accuracy. Some of this would be done autonomously. While we are not quite there yet, KidsArm is able to perform three to five suture points autonomously.
The KidsArm platform is being tested in a research environment at SickKids in an effort to develop technologies related to minimally invasive automated anastomosis — the union of tubular structures such as blood vessels to each other or to surfaces. The robot uses camera-based tracking of tissue and desired suture points, automated positioning and automated application of sutures. The results of this study will inform the next level of development for the robot......read more
Study Finds Improved Accuracy and Safety Utilizing Mazor Robotics Renaissance Guidance System
August 21, 2014
Utilization of Mazor Robotics (TASE:MZOR) (NASDAQCM:MZOR) Renaissance Guidance System provides greater reliability in screw placement and reduced use of fluoroscopy, according to a prospective study published in the current issue of Turkish Neurosurgery.1
The study, led by Dr. Mehmet Resid Onen, Umraniye Training and Research Hospital, Department of Neurosurgery, Istanbul, reviewed 27 patients who underwent thoracolumbar stabilization operations aided by Renaissance at the hospital during 2012-2013. The accuracy rate of pedicle screw positioning with the system was found to be 98.5 percent2, and no neurological, vascular or dural damage was observed in the case series.
According to the investigators, while the use of percutaneous instrumentation holds a superior advantage over open procedures, the localization and orientation of percutaneous placed implants are completely dependent on the use of fluoroscopy. With the Renaissance system, an average of only 1.3 seconds of fluoroscopy was used per screw and 40 percent of patients' implants were instrumented percutaneously. The study noted that the total surgery duration in patients who undergo multi-level instrumentation is reduced because of the decrease in the time that is typically lost in gaining x-ray images to determine the screw location.....read more
Death after robotic surgery: FIR lodged against five Gangaram docs
August 20, 2014
Wife of Military Engineering Service officer died after robot assisted surgery last year
An FIR ( First Information Report ) has been registered against five doctors of Sir Gangaram hospital for causing death due to negligence on the directions of a Delhi court. The order came in a 2013 case, where the wife of a Military Engineering Service officer posted with the Indian Air Force died after a robotic surgery for retroperitoneal fibrosis, or the presence of fibroids around the kidneys and renal tract.
In the FIR, the woman’s husband alleged that a critical artery supplying blood to the kidneys was accidentally cut during the surgery, leading to excessive bleeding.
The FIR was registered at Rajender Nagar police station under Section 304(A) against Dr Sudhir Khanna, the urology surgeon who conducted the surgery, Dr Sanjay Mittal and Dr Manju Gupta, his colleagues from the same department, Dr V S Bedi, vascular surgeon, and Dr Anurag Gupta from nephrology on August 6 following a June 19 order by a metropolitan magistrate in Tis Hazari court.
According to the FIR filed by Devi’s husband Prem Kishore, the doctors’ team, headed by Khanna, “… negligently cut the external iliac artery, which resulted in immediately heavy blood loss, but instead of repairing the iliac artery at the earliest and taking immediate remedial measures, doctors continued the robotic surgery for another three hours approximately”.
Kishore said according to medical records provided by the hospital, his wife lost three litres of blood in the surgery, which resulted in “acute kideny failure”......continue reading

AKE DANNA STEVENS / STAFF PHOTOGRAPHER Barbara Plucknett, M.D., works with the da Vinci Si surgical system to perform operations at Regional Hospital of Scranton.
Robotics transform way surgery is performed
August 10, 2014
From 2000 to 2012, the number of robotic surgical procedures worldwide jumped from 1,000 to 450,000, according to a 2013 article published by the Wall Street Journal. Geisinger Wyoming Valley Medical Center in Wilkes-Barre offers a da Vinci surgical system, but Regional marks the first Scranton hospital to dive into robotic-assisted surgery.
Launched in April 2009, the da Vinci Si is a four-armed robot. Tiny instruments, such as scissors or forceps, are mounted on three separate arms, while the fourth arm is outfitted with a 3-D camera and a light that guides the surgeon.
Experts tout robotic surgery as a way to perform more complicated minimally invasive procedures, because the instruments bend and rotate far greater than a human’s wrist. Compared with open surgery, the less invasive technique normally leads to shorter hospital stays and less pain and blood loss.
Critics argue that most of the benefits stem from the fact that it’s a minimally invasive procedure, not that it’s robotic. They point to laparoscopic surgery, in which surgeons guide specialized tools and a video camera by hand through small incisions, as a cheaper, viable alternative.
Others say doctors use it as an advertising tool more than a surgical tool, said Jason G. Newman, M.D., director of head and neck surgery at Pennsylvania Hospital in Philadelphia........Click here to read complete article
New Neurosurgical Robot for UAMS August 8, 2014 Through a donation of $402,000 by the late Edwin “Brad” Bradberry, the University of Arkansas for Medical Sciences (UAMS) Medical Center recently purchased a neurosurgical robot, ROSA, to be used in stereotactic procedures for epilepsy and oncology.
Use of the device makes procedures less invasive, significantly shorter, and much safer by improving surgical accuracy, while minimizing the risks of pain or infection.
UAMS is one of only five medical centers in the United States to have a ROSA (Robotized Stereotactic Assistant). Stereotactic surgery uses a three-dimensional coordinate system to locate small targets in the body for minimally invasive surgery.
Neurosurgeon and epilepsy specialist Demitre Serletis, M.D., Ph.D., leads the Epilepsy Surgery Program in the UAMS Department of Neurosurgery and is an assistant professor in the UAMS College of Medicine.
“By integrating cutting-edge robotic technology such as the ROSA device into the university’s comprehensive Epilepsy Surgery Program, the Bradberrys’ contribution goes a long way toward developing an even greater standard of exceptional patient care and research at our center, the newly established Edwin and Karlee Bradberry Center for Robotic Neurosurgery,” said Serletis......read more
Controversial Study Links Vasectomy to Prostate Cancer
August 7, 2014
Leading Prostate Surgeon Dr. David Samadi Weighs In on Study
A new study published last month in The Journal of Clinical Oncology indicates that there may, in some cases, be a link between vasectomies and an increased risk of contracting the most lethal form of prostate cancer. A vasectomy is a surgical procedure for male sterilization, providing a permanent form of birth control. During the procedure, the vasa deferentia are severed, tied and sealed to prevent the release of sperm.
The study is a culmination of 24 years of research released by Harvard School of Public Health. Researchers at Harvard analyzed the data on 49,405 U.S. men who ranged in age from 40 to 75 years in the Health Professionals Follow-Up Study. Of those 12,321 men who had vasectomies -- or 25 percent of study participants -- researchers discovered 6,023 cases of prostate cancer from 1986-2010. Among those cases, 811 were lethal.
World-renowned robotic prostate surgeon David B. Samadi, MD, Chairman of Urology and Chief of Robotic Surgery at Lenox Hill Hospital, says that this is just another reminder that early detection and regular screenings for prostate cancer are imperative.....continue reading
Voice-controlled robot makes complex gynaecological surgeries easier
August 7, 2014
SINGAPORE: Patients undergoing gynaecological surgery will now be able to benefit from a new voice-controlled robotic system at the Singapore General Hospital (SGH).
The ViKY Uterus Positioner (ViKY UP) robot, operated via wireless Bluetooth headset, is a motorised device that uses voice commands to control the positioning of the uterus during complex gynaecological surgeries.
Traditionally, an assisting technician controlled the position of the uterus manually during surgery. This can be challenging as when the assistant gets fatigued, it becomes difficult for them to maintain the traction required on the uterus during the procedure's critical phases.
Dr Peter Barton-Smith, Senior Consultant with the Department of Obstetrics & Gynaecology at SGH, elaborated: "For very complex cases which three, four or five hours, it's a long time to be sitting, holding the device and doing it in an accurate way and keeping it still. The system allows us to keep a steady field of view exactly where we want the position of the uterus to be, which then frees up that junior doctor for other duties or potentially to have a better learning experience in the operating theatre."..........read more
'No difference' between open surgery and robotic surgery
August 1, 2014. Source: MedicalNewsToday
In particular, a high-profile study by surgical oncologists at Memorial Sloan-Kettering Cancer Center in New York, NY, found no difference in terms of rates of complications or length of hospital stay between traditional open surgery and robotic surgery for bladder cancer.
What is more, the researchers found the results so clear-cut that they stopped the trial early. They described their peer-reviewed findings in the New England Journal of Medicine.
However, Intuitive Surgical objected to the Sloan-Kettering research, labeling it "grossly misleading" in a statement.
Speaking with Medical News Today, Dr. Catherine Mohr, vice president of medical research at Intuitive Surgical, explained that the randomized study is misleading because it compares open surgery procedures with hybrid procedures, which are a mixture of robotic and open elements.
When the researchers concluded that there were no differences in complications between the two procedures, Mohr claims that - rather than comparing the robotic and open procedures - they were actually comparing the same open technique used in both arms of the study.
"In essence, this letter to the editor is comparing open surgical complications to open surgical complications with a robotic dissection, and then concludes they are the same," Dr. Mohr asserted. "Attempting to generalize this study, which compares open to hybrid, and then to imply that the latter surgery is entirely minimally invasive is grossly misleading."
Medical News Today contacted Dr. Bernie Bochner, lead author of the Sloan-Kettering study for comment, but he was unable to reply before our deadline.
In gastric surgery, a recent Australian review of six randomized trials also found "no appreciable difference" between conventional minimally invasive anti-reflux surgery and robot-assisted anti-reflux surgery in complication rates, post-operative symptoms, quality of life or functional assessments.
Although older studies comparing the outcomes and costs of open and robotic cystectomy have been favorable toward the robots, it seems that much recent research - with the exception of a survey of hysterectomy patients conducted by Intuitive Surgical employees - is finding few advantages to the robotic system.
