Colon cancer surgery is a common treatment option for colon cancer. The two main approaches for colon cancer surgery are open surgery and minimally invasive surgery, which can be performed using laparoscopic or robotic tools [1]. In this document, we will discuss the procedure of a colon cancer surgery using robotic surgery.


A robotic-assisted procedure for colon cancer surgery involves the use of a few small abdominal incisions, each about the size of a dime, to insert the surgical instruments into the abdominal cavity [2]. A long and thin lighted tube with a camera on the end, called a laparoscope, is also inserted through one of the incisions to provide a view of the inside of the abdomen.

The surgeon sits at a console in the operating room and controls the robotic arms using hand and foot controls. The robotic arms hold the surgical instruments and are inserted through the small incisions in the abdomen. The surgeon uses the robotic arms to remove the diseased tissue from the colon.

In some cases, a larger incision may be required to remove the diseased tissue [2]. The surgeon may also remove nearby lymph nodes during the procedure to determine whether the cancer has spread.

Advantages of Robotic Surgery

Robotic surgery has several advantages over traditional open surgery for colon cancer. The smaller incisions used in robotic surgery lead to less pain and scarring, a shorter hospital stay, and a quicker recovery time compared to open surgery [1]. Additionally, robotic surgery provides the surgeon with a three-dimensional view of the surgical site and allows for more precise movements with seven degrees of robotic arms [1].


Robotic surgery is a safe and effective treatment option for colon cancer. It is a minimally invasive procedure that requires only a few small incisions in the abdomen, resulting in less pain and scarring and a quicker recovery time compared to open surgery. Thanks to the robotic arms, the surgeon can perform more precise movements and remove the diseased tissue with greater precision.
