Colon Resection Surgery

Learn about minimally invasive options for colon resection surgery, also known as a colectomy. Common procedures include hemicolectomy and sigmoid colectomy.

There’s more than hope when you know the facts

More than 600,000 colon surgeries are performed in the US each year.1 There are several conditions that may prompt your doctor to recommend colon surgery. They can range from benign (noncancerous conditions), like bowel blockages, diverticulitis, inflammatory bowel diseases including Crohn’s, or ulcerative colitis, to cancer conditions, like colon cancer. Surgeons can remove the diseased section of the colon, along with nearby lymph nodes, with a procedure called a colectomy.

It’s important to learn about the many options for care available. You and your doctor can discuss your choices and decide which approach is right for you. On this page, you’ll find information on types of colectomies, how they are performed, questions you can ask your doctor, and how to find a surgeon who performs colon surgery with the da Vinci system.

What is colon resection surgery?

Colon resection is known as a colectomy. There are several types, including hemicolectomy and sigmoid colectomy. Your surgeon will recommend options best for you based on your particular condition, symptoms, and age.

Minimally invasive colectomy

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 instruments and a camera for viewing. In laparoscopic surgery, doctors use special long-handled tools while viewing magnified images from a laparoscope (camera) on a video screen.

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 the da Vinci system is appropriate for your situation. You should always ask your surgeon about his or her training, experience, and patient outcomes.

Ask your surgeon about their robotic surgery outcomes

Every surgeon's experience is different. Be sure to talk with your surgeon about the surgical outcomes they deliver using the da Vinci system. For example, ask about:

  • Length of hospital stay
  • Complication rate
  • Rate of returning to the hospital within 30 days of surgery
  • Reoperation rate
  • Transfusion and/or blood loss
  • Chance of changing to an open procedure
  • Length of operation
  • Return to bowel function
  • Mortality rate

There are additional surgical outcomes you may want to talk about with your doctor. Please ask to discuss all important outcomes. Every surgery involves risk and you can read more about those associated with colectomy.
