What Is Colon Cancer?

The colon and the rectum are the end sections of the GI tract that are lined with millions of cells which are frequently replaced. Over time, these cells can be exposed to bacteria, subjected to toxins from food, and go through wear-and-tear as the body ages. When cells are no longer functioning optimally, they are replaced with new ones. Occasionally, mistakes are made when making these new cells which cause them to appear abnormal. Sometimes, they can also see growth at uncontrolled rates. These types of cells are known as cancerous cells.

What Are the Symptoms of Colon Cancer?

There are several symptoms of colon cancer, and they can vary. They can include:

  • Abdominal pain or tenderness in the lower abdomen
  • Bloody stool
  • Diarrhea, constipation or other changes in bowel functions
  • Narrower than normal stools
  • Unexplained anemia
  • Unexplained weight loss
  • Bloating, fullness or cramps
  • Vomiting

Colon Resection Surgery

Learn about colectomy surgery and understand your options

There’s more than hope when you know the facts

Your large intestine, which includes the colon, rectum and anal canal, plays a vital role in keeping you healthy by absorbing water and minerals and eliminating food waste. Because of the role it plays in digestion, conditions that affect the large intestine can be life-threatening. Even less dangerous colon conditions can reduce your quality of life and harm your overall health. 

Common conditions of the colon that bring people in for medical care include cancer. Colon cancer is the third most common cancer diagnosed in the U.S. each year, with more than 100,000 new cases expected in 2019.1 Other potentially serious conditions affecting the colon include inflammatory bowel diseases (IBDs) such as Crohn’s disease and ulcerative colitis, diverticulitis (small pouches that become inflamed or infected), and bowel blockages.

Understanding your options

There are several options for managing some noncancerous colon conditions, including medications and changes to your diet and lifestyle.2-4 If these options fail to relieve symptoms, your doctor may suggest surgery. 

If you have been diagnosed with colon cancer your doctor may recommend chemotherapy, targeted therapy, immunotherapy, radiation therapy, surgery to remove the affected colon and nearby lymph nodes, or a combination of these options depending on the type of cancer and how far it has advanced.5

Surgeons can remove the diseased section of the colon, along with nearby lymph nodes, with a procedure called a colectomy. After the surgeon has removed the diseased section of your colon, he or she may then reattach the two healthy parts of the intestine, performing what is known as an anastomosis. This part of the operation can either be done completely inside the body (known as an intracorporeal anastomosis) or outside of the body (known as an extracorporeal anastomosis).

The surgeon can perform a colectomy through open surgery or a minimally invasive approach. Traditional open surgery requires the surgeon to make an incision in your abdomen large enough to see the colon and perform the procedure using hand-held tools.

There are two minimally invasive approaches for colectomy: laparoscopic or robotic-assisted surgery, possibly with da Vinci technology. Both minimally invasive surgical options require a few small incisions that doctors use to insert surgical equipment and a camera for viewing. In laparoscopic surgery, doctors use special long-handled tools to perform surgery while viewing magnified images from the laparoscope (camera) on a video screen.

How da Vinci works

Surgeons using da Vinci technology may be able to remove part or all of your colon through a few small incisions (cuts). During surgery, your surgeon sits at a console next to you and operates using tiny, wristed instruments. The da Vinci system translates every hand movement your surgeon makes in real time to bend and rotate the instruments with precision. 

A camera provides a high-definition, 3D magnified view inside your body. Your surgeon may use Firefly® fluorescence imaging, which offers visualization beyond the human eye by activating injected dye to light up and clearly show the blood flow to the colon. This may help your surgeon during the procedure.

It’s important to remember that Intuitive does not provide medical advice. After discussing all options with your doctor, only you and your doctor can determine whether surgery with da Vinci is appropriate for your situation. You should always ask your surgeon about his or her training, experience, and patient outcomes.

More About Da Vinci

Why surgery with da Vinci?

A review of published studies suggest that potential benefits of a colectomy with da Vinci technology include:

  • Patients may experience fewer complications compared to patients who had open6,7 and laparoscopic8-11 surgery.
  • Patients may stay in the hospital for a shorter amount of time than patients who had open6,12 or laparoscopic6,8-10,13,14 surgery.
  • Surgeons may be less likely to switch to an open procedure when performing surgery with da Vinci, compared to a laparoscopic surgery.6-8

All surgery involves risk. You can read more about associated risks of colectomy here.
