First case! Da Vinci single-port robot completes oropharyngeal cancer surgery
Recently, the University of Mississippi Medical Center (UMMC) announced the completion of the first single-port robot-assisted oropharyngeal cancer surgery.
The number of oropharyngeal cancer cases is increasing, and the lifetime risk of oral and oropharyngeal cancer is approximately 1/60 for men and 1/141 for women. However, from 2009 to 2020, oropharyngeal cancer related to human papillomavirus (HPV) infection increased by 1.3% per year in women and 2.8% per year in men.
#Oropharyngeal Cancer Robotic Surgery Therapy
Transoral Robotic Surgery (TORS) technology allows surgeons to remove benign and malignant tumors from a patient's mouth and throat, outperforming previous treatments in identifying the primary site. TORS has also been shown to be effective in reducing the need for radiation and chemotherapy after surgery, often without the need for additional treatments. Low-risk cases can be treated with surgery alone, while in intermediate- and high-risk cases, TORS can reduce the dose of radiation therapy and often does not require chemotherapy.
Dr. Anne Kane said: "In the past, when trying to identify the primary tumor, an oscilloscope was used to take biopsies of different areas of the mouth and throat, and the success rate was about 40%. Through robot-assisted surgery, the recognition rate has increased to about 70%. In the right treatment candidates, TORS has the opportunity to reduce the long-term side effects of treatment while effectively treating cancer. "
UMMC has completed more than 70 robot-assisted surgeries in the past few years, using the first-generation da Vinci SI and the third-generation da Vinci XI porous robotic systems.
#UMMC completes first surgery using da Vinci SP
UMMC surgeons said that the addition of this state-of-the-art robotic technology will provide better surgical outcomes for patients and will also advance UMMC's robotic surgery program.
Dr. Paula Domino is a urological surgeon and the first doctor in Mississippi to perform surgery using the da Vinci SP. She said the treatment outcomes of da Vinci SP single-port robotic surgeries are often similar to or even better than surgeries performed using multiport robots. The surgical incision of only one inch gives patients excellent cosmetic results and does not require the prescription of narcotics. Patients can also be discharged early and complete their recovery at home.
Currently in the United States, the da Vinci SP System is approved for single-port urological surgery, oropharyngeal lateral resection (commonly known as radical tonsillectomy), and tongue base resection. Designed to provide precise assistance in minimally invasive surgeries, this cutting-edge single-hole robot is tailor-made for performing complex surgeries deep inside the body or organs. The streamlined design provides 360 degrees of anatomical contact, and the single arm avoids external collisions.
The da Vinci system translates the surgeon's hand movements in real time to manipulate and adjust instruments during surgery. These tiny wrist instruments mimic human hand movements and allow for a greater range of motion. Endoscopes allow surgeons to view specific areas from all angles during surgery with enhanced three-dimensional and high-definition resolution. This provides the surgeon with a clear and highly magnified view of the surgical field, and the instrument is designed to be small, allowing the surgeon to operate through only one or a few small incisions.

The da Vinci SP surgical robot consists of three parts, the Patient Cart, the Surgeon Console, and the Vision Cart. Different from Xi and The casing includes three multi-joint instruments and a full-wrist 3D high-definition camera to help doctors visualize and control in narrow surgical spaces.
The tool inside the casing has the ability to simulate the full range of rotation of the human wrist and elbow, and can perform precise surgical operations up to 24 centimeters deep into the wound. It becomes a natural extension of the surgeon's eyes and hands by combining innovative robotics, 3D high-definition stereoscopic vision and intuitive controls.

Another advantage of the da Vinci SP is its high accessibility, which can be placed from one port to any position within 360° for dissection. The da Vinci SP boom can rotate more than 360° around the distal center of the casing and rotate the instrument cluster inside the casing more than 360°.
Currently, da Vinci SP has been approved for several types of surgeries in Japan and South Korea. The FDA has approved da Vinci SP for use in urological surgeries and transoral otolaryngology surgeries in the United States, but it is not suitable for general laparoscopic surgery.
