Dr. Jeffrey Ferris MD and Dr. David Lisle MD Colorectal Robotic Surgeons

P. Jeffrey Ferris, MD, Chief of Colon and Rectal Surgery, and David Lisle, MD, Colon and Rectal Surgeon

Robotic technology allows our colorectal surgeons to operate with extreme precision. Areas of the intestines or colon that may difficult or even impossible to reach with the human hand are now accessible with use of the robotic system; its “arms” can rotate up to 280 degrees. All of this translates to a better experience, as well as outcomes, for you, as the patient.

Benefits of Robotic Surgery for Patients

Patients who have undergone colorectal robotic surgery may tell you the recovery process is greatly simplified, and much easier than what they expected. Blood loss during the procedure is reduced. Post-operation pain is minimized. Most find that their hospital stay, recovery period, and time away from work or normal, day-to-day activities, is much shorter.

MedStar Franklin Square Medical Center’s investment in robotic surgical tools positions us “ahead of the curve” when it comes to the integration of technology in our day-to-day work. And along with that, some of the region’s most skilled surgeons are part of our colorectal team; doctors who offer second-to-none clinical capabilities, and who are also truly committed to serving as leaders in today’s evolving world of medicine.

Frequently Asked Questions

This is one of the most frequently asked questions we hear! Your colorectal surgeon fully controls the entire procedure - NOT the robotic technology. The technology is a tool and does not replace the role of your surgeon during your procedure.

During a standard laparoscopic procedure, your colorectal surgeon stands next to the operating room bed and utilizes hand-held instruments to perform your procedure. This requires a series of small incisions. Using robotic technology, instead, your surgeon is seated at a console, using their own hands to maneuver the arms and instruments of the da Vinci system. Again, this requires just a few small incisions. From that console, your surgeon has 3D vision and the ability to rotate his or hands in angles and to degrees that would otherwise be impossible to achieve.

Robotic surgery is safer and typically results in a number of key benefits for colorectal patients, including:

  • less blood loss
  • less pain after surgery
  • shorter hospital stay
  • quicker recovery
  • quicker return to work and normal life activities

This technology was approved for use in the U.S. by the Food and Drug Administration (FDA) in 2000.

MedStar Franklin Square houses two da Vinci robotic surgical systems in our operating room suites. In total, since investing in the technology in 2009, our surgeons have performed more than 4,000 robotic procedures.
