Robotically Assisted Surgery

Robotically Assisted Surgery at Methodist is an extremely precise, minimally invasive, and highly effective alternative to conventional chest, abdominal and prostate cancer surgery. Conventional procedures of this type require large incisions, while robotically assisted technology allows surgeons to work through 1-2 cm incisions with better vision.

Benefits are significant. There is less damage to surrounding healthy tissue, patients experience less pain, blood loss and complications, and the recovery time is shorter.

The surgical robotics system is completely under the surgeon’s control and replicates the surgeon’s movements in real time. It cannot be programmed or make decisions on its own. The surgeon sits at a console and uses a thumb and forefinger to manipulate robotic arms that have specific functions. The patient lies on a regular surgical bed and is monitored by an anesthesiologist and specially trained surgical staff members who change the functions of the robotic arms by simply snapping a laser or certain type of scalpel in place.

Dr. Krishnan is a fellow of the American College of Obstetricians and Gynecologists, American Institute of Ultrasound Medicine and American Association of Gynecologic Laparoscopists. She is one of the first ob-gyns in this area to receive accreditation to perform robotically assisted gynecologic surgery.

Thomas H. Metcalf, MD, Obstetrician-Gynecologist
Dr. Metcalf is among the first obstetricians-gynecologists in this area to perform robotically assisted gynecologic surgery. A graduate of the University of Tennessee College of Medicine, he is a fellow of the American College of Obstetricians and Gynecologists, American Medical Association, and American Association of Gynecologic Laparoscopists. Dr. Metcalf is board certified in obstetrics and gynecology.

Scott Peters, MD, Obstetrician-Gynecologist
Dr. Peters, a board-certified obstetrician-gynecologist at Methodist, was the first physician at this medical center to perform a gynecological procedure using the da Vinci robotic system. He earned his medical degree from the Oklahoma Health Sciences Center and completed general surgery and ob-gyn residencies in Tulsa, Okla. He is a fellow of the American College of Obstetricians and Gynecologists and the American College of Surgeons.

Andwylynn Sances, MD, Obstetrician-Gynecologist

A member of the American College of Obstetrics and Gynecology, Dr. Sances joins a small number of ob-gyns in this region who are accredited to approve robotically assisted gynecologic surgery.

Brandon Cottrell, MD, Urologist
Dr. Cottrell is one of an elite number of board-certified urologists trained in performing robotically assisted prostate cancer removal. He is a graduate of University of Tennessee College of Medicine and completed a general surgery and urology residencies at University of Arkansas Medical Sciences.

Adam Shrewsberry, MD, Urologist
Dr. Shrewsberry is one of an elite number of board-certified urologists trained in performing robotically assisted urologic surgeries, including prostatectomies (prostate cancer removal), partial nephrectomies (kidney cancer removal), and pyeloplasties (correcting a blocked kidney). He is a graduate of Emory University School of Medicine where he also completed his urology residency.
