Rectal Resection Surgery

Learn about minimally invasive options for rectal resection surgery. One common procedure is a low anterior resection.

There’s more than hope when you know the facts

There are a number of conditions that may result in your doctor recommending rectal surgery. The most common condition is cancer, but benign (noncancerous conditions), like rectal prolapse can also result in rectal surgery.

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 rectal resection surgeries, how they are performed, questions you can ask your doctor, and how to find a surgeon who performs rectal surgery with the da Vinci system.

What is rectal resection surgery?

Rectal resection surgery is the removal of the diseased section of the rectum. If you have been diagnosed with rectal cancer your doctor may recommend a combination of options that includes rectal resection, depending on the type of cancer and how far it has advanced.1

Minimally invasive rectal surgery

The surgeon can perform a low anterior resection 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 rectum and perform the procedure using hand-held tools.

There are two minimally invasive approaches for lower anterior resection: 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 the 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 rectal resection surgery.
