From sci-fi to reality

Patients benefit from improved care and quicker recovery with robotic surgery

Surgery can be intimidating, especially the idea of robots performing it. Robotic surgery is real and not just a headline out of a sci-fi novel. But instead of being intimidating, the new robotic technology is a high-tech improvement that enables surgeons to perform a host of common procedures in a less-invasive manner. Dameron Hospital is now offering this medical technology to the people of Stockton and the surrounding communities with the da Vinci Xi surgical system.


When conducting robotic surgery, our surgeons are now able to perform general surgery with minimally invasive techniques. Coupled with the surgeon's expertise, the da Vinci Xi surgical system, also known as "LISA" (Less Invasive Surgery Assistant) by our Dameron surgery team, mimics the surgeon's hand movements while enabling big movements to be scaled down. This state-of-the-art system offers advantages like better scopes and higher visibility to provide surgeons with greater capabilities. The technology changes how general surgeries are performed at Dameron by improving patient care and making it even faster for patients to return to their normal activities.

Why robotic surgery?

Robotic surgery was developed to overcome many of the limitations of traditional laparoscopic or open surgeries. Apart from the superior visualization offered, the robot also enables more precise instrumentation and surgical skill. Some of the patient benefits of minimally invasive robotic surgery can include:

  • Smaller incisions.
  • Less pain.
  • Low risk of infection.
  • Short hospital stays.
  • Quick recovery times.
  • Reduced blood loss
  • Fewer complications, pre- and post-op.
  • Reduced appearance of scarring.
  • Faster return to normal daily activities.

It's important to know that surgery with da Vinci Xi does not mean a robot performs the surgery. The surgeon is in complete control of the instruments at all times. It uses a suite of closely grouped stations: a console from which a surgeon manipulates instruments, the robot at the patient's bedside, and a three-dimensional color monitor.

Better patient outcomes

Previous models of the da Vinci robot require it to be positioned in one area, making it difficult to maneuver for complex general surgeries. The newer da Vinci Xi robot offers surgeons greater capabilities and mobility. It translates the surgeon's hand movements into smaller, more precise movements that can direct small surgical instruments in and around the patient's body to perform complex surgeries with ease. Additionally, the Xi model is equipped with technology that allows the sealing and stapling of major blood vessels and organs.

Dinesh Vyas, MD, MS, FACS, general surgeon at Dameron, is a world-acclaimed specialist in robotic surgery. He is quick to note the many merits that robotic surgery affords both to the surgeon and the patient.

"One of the most noteworthy technological advancements of the da Vinci Xi surgical system at Dameron is its ability to offer more flexibility for me in terms of operating on parts of the body that under normal circumstances were not an option," he says. "We can now offer extensive colon resections, splenectomies and other more advanced surgeries using this revolutionary technology."

Dr. Vyas recently performed a complex splenectomy on a patient using the da Vinci Xi surgical system and was able to fully visualize the surgical field. There, he discovered multiple issues and responded quickly and with the utmost precision (see patient story below).

"For this case and many other complex cases like it, the robot enables me to have greater maneuverability in a small space," says Dr. Vyas. "When you're working with small blood vessels and tissue, like in the case of a spleen, you need to be as precise as possible. The robotic technology significantly enhances minimally invasive surgery. Patient outcomes are vastly improved, and there is often less pain postoperatively with shorter recovery times."

Minimally invasive options with da Vinci Xi

Over the past five years, general surgery has been the fastest-growing segment of robotic surgery. The da Vinci Xi system enables surgeons to operate with even greater vision and control and allows them to perform more types of surgery with incredible precision and less risk.

Dameron offers many minimally invasive procedures, including:

  • Colorectal surgery.
  • Rectal prolapse surgery (rectoplexy).
  • Adrenal surgery (adrenalectomy).
  • Hernia surgery and repair.
  • Gallbladder surgery (cholecystectomy).
  • Weight-loss surgery (bariatric surgery).
  • Liver resection surgery.
  • Bowel resection surgery.
  • Spleen surgery (splenectomy).
