RoboDoc: deft mechanized hands aid Memphis surgeons in operating rooms

Source: www.commercialappeal.com Author: Tom Charlier The cancer in James Entrekin's throat has curdled around the base of his tonsils, way too far down for a traditional surgeon to reach without doing a lot of cutting and bone-breaking. But there's nothing traditional about the surgery going on in this Methodist University Hospital operating room. Employing nimble, cable-thin arms, a robot reaches into Entrekin's mouth while wielding four instruments at once -- removing tumors, cauterizing vessels, suctioning fluids and transmitting three-dimensional video images of the whole thing. In a couple of hours, it's over. And since there was no need to cut open his face and throat and break his jaw, as is done in conventional oral-cancer surgeries, Entrekin will enjoy a lower risk of complications and a much shorter recovery period, while avoiding extended difficulties swallowing and speaking. "You avoid all that because that natural anatomy is not violated," says Dr. Sandeep Samant, who guided the robot from a console in a corner of the operating room. Although there are many types of surgeries where they can't be used, robots such as the nearly $2 million device used in Entrekin's case are carrying an ever-growing workload in the operating rooms of Memphis hospitals. Less than a decade after robotic surgery was introduced in Memphis, there now are five robots -- one each in Methodist University, Methodist North and Methodist Germantown and two at Baptist Memorial Hospital-Memphis -- performing roughly 1,000 operations annually. They're doing hysterectomies, removing prostates and kidneys, [...]

University of Rochester expands robotic surgeries to oral, pharyngeal cancers

Source: www.healthcanal.com Author: staff Doctors at University of Rochester Medical Center are first in upstate New York to incorporate the precision and dexterity of a surgical robot to remove cancerous tumors in the mouth and throat. The first transoral robotic procedure – a partial glossectomy -- was performed Feb. 8 by surgeon Matthew Miller, M.D. This procedure expands the Medical Center’s robot-assisted surgery capabilities to include procedures for head and neck, urologic and gynecologic conditions. “Traditional approaches to these tumors have the potential to be invasive and disfiguring – oftentimes leading to an extensive recovery and rehabilitation period,” said Miller, a fellowship trained head and neck cancer surgeon. “The robot allows us to limit or even eliminate some of the side effects associated with more invasive surgeries while still effectively treating the cancer.” Strong Memorial Hospital’s daVinci Surgical Systems consist of robotic arms that replicate a surgeon’s motions in real time. The movements are by a surgeon using high-definition images provided by cameras positioned within the patient’s mouth. The surgeon is working from a console, across the room from the patient. Traditional surgery for some head and neck cancers requires large incisions – extending from the lip, across the chin and to the neck before entering the mouth or throat. Many times surgeons need to cut through the lower jaw and move aside vital cranial nerves to gain access to the back of the mouth and throat. Using the high-precision robotic system, surgeons insert the slender instruments into the mouth [...]
