Robotic surgery represents the most significant advancement in minimally invasive surgery in decades — and the team at Surgery Group LA has been performing it since its earliest adoption.
When you choose robotic surgery at Surgery Group LA, your surgeon operates using the da Vinci® Surgical System — the world’s most widely used robotic surgical platform, backed by 38,000+ peer-reviewed studies and used in more than 14 million procedures worldwide.
Your surgeon sits at a console and controls highly precise robotic instruments through small incisions — roughly the size of a dime. A 3D high-definition camera provides a magnified, crystal-clear view of the surgical site. The robot does not act independently: every movement is your surgeon’s movement, enhanced.
Robotic techniques for colon cancer, rectal cancer, diverticulitis, and complex anorectal conditions. Dr. Nasseri, Dr. Barnajian and Dr. Ellenhorn are among the most prolific robotic colorectal surgeons in Los Angeles.
Robotic hernia repair allows for precise mesh placement with minimal trauma to surrounding tissue — particularly beneficial for complex, recurrent, or large hernias that require extra surgical precision.
Robotic cholecystectomy offers a precise alternative to laparoscopic gallbladder removal, with excellent visualization of the bile duct anatomy and reduced risk of injury to adjacent structures.
Minimally invasive robotic cancer surgery for colon, rectal, and other abdominal malignancies.
Precise robotic excision of endometriosis lesions with minimal tissue trauma and improved surgical outcomes.
Surgery Group LA operates with the latest generation da Vinci® Xi and SP systems — the most advanced robotic surgical platforms available. The da Vinci® system translates your surgeon’s hand movements into precise, controlled motions inside your body, with a range of motion that exceeds the human hand.

Is robotic surgery safe?
Yes. Robotic surgery has been used in millions of procedures worldwide, with safety records comparable to or better than traditional laparoscopic techniques. Your surgeon controls every movement of the robotic instruments at all times — the system cannot operate autonomously.
How is robotic surgery different from laparoscopic surgery?
Both are minimally invasive, but robotic surgery offers enhanced precision, 3D visualization, and greater instrument dexterity. The robotic platform allows surgeons to perform complex movements more reliably, particularly in confined anatomical spaces.
Will I feel the robot during surgery?
No. You will be under general anesthesia during the procedure. You will not feel any sensation from the robotic instruments.
How long is recovery from robotic surgery?
Recovery times vary by procedure, but robotic surgery typically results in shorter hospital stays, less pain, and faster return to normal activity compared to open surgery. Many patients go home the same day or within 24 hours.
Is robotic surgery covered by insurance?
Most major insurance plans, including Medicare and Medi-Cal, cover robotic surgery when it is medically indicated. Our team will work with your insurer to verify coverage prior to your procedure.
Who performs the robotic surgery?
Your procedure will be performed by one of Surgery Group LA’s fellowship-trained robotic surgeons. The robot does not perform surgery autonomously — it is controlled entirely by your surgeon at all times.
Symptoms like itching, swelling, and occasional bleeding during bowel movements may indicate hemorrhoids. A professional evaluation can confirm the diagnosis.
More importantly, our team of world-renowned surgeons have saved countless lives, and have enabled countless more to live healthy, happy lives.
Our board-certified surgeons at Cedars-Sinai are available for in-person and telehealth consultations. Most patients are seen within one week.
