At Memorial Sloan Kettering, surgery is the most common treatment for many stages of rectal cancer. If you or someone you care about has been diagnosed with rectal cancer, we want to help you understand the surgical options so that you have the best outcome possible. This information can help prepare you for the decisions you and your doctors will make together.
As with many kinds of cancer, early detection is critical. Surgery alone can often be the only necessary treatment for small tumors that haven’t spread through the rectal wall. Sometimes a tumor can be removed though the anus without removing the entire rectum. Other people will need to have most or all of the rectum removed. Cancer that has spread through the wall of the rectum or to nearby lymph nodes usually requires chemotherapy and radiation in addition to surgery.
Surgery for rectal cancer does have some challenges. For example, the pelvis contains many narrow parts, making the area difficult to operate on. This region also contains the nerves that control your ability to use the bathroom as well as those that affect your sexual health. Your MSK surgeon will take every precaution to protect those nerves. Some rectal cancer is likely to come back after surgery.
- How do surgery, chemotherapy, and radiation therapy work together to treat rectal cancer?
- Will I need a colostomy bag after rectal cancer surgery?
- How does MSK help quality of life after surgery for rectal cancer?
- What is minimally invasive surgery for rectal cancer?
- Why should I choose MSK for rectal cancer surgery?
- What kind of support will I get after rectal cancer surgery at MSK?
Because it’s more challenging to operate within the pelvis, chemotherapy and radiation therapy may be used to shrink rectal tumors before surgery, especially larger tumors. This approach is called neoadjuvant therapy. If you’re a candidate for this therapy, your care team will work with you to determine which combination is right for you.
At MSK, neoadjuvant therapy is the standard recommendation for advanced rectal cancer that hasn’t spread or a tumor close to the anus. If you have advanced cancer that has spread to the lymph nodes, a combination of chemotherapy and radiation therapy before surgery can kill microscopic cancer cell growths before they get bigger. This can reduce the risk of the cancer coming back.
Neoadjuvant therapy followed by surgery and chemotherapy gives people with rectal cancer that hasn’t spread an overall cure rate of more than 70 percent. Rectal cancer comes back in less than 10 percent of people who have this sequence of treatment.
MSK surgeons are constantly developing new, more effective techniques to protect the ability to use the bathroom normally in people who’ve had rectal cancer surgery.
For example, in the past, many people needed a permanent colostomy. This is a surgical procedure that removes the rectum and brings one end of the large intestine out through the abdominal wall. People who have a permanent colostomy are fitted with an ostomy pouching system. This is commonly called a colostomy bag. The bag collects waste from the intestine. People with a permanent colostomy use a bag to collect waste for the rest of their lives.
At MSK, the overwhelming majority of people with rectal cancer can now avoid a permanent colostomy, thanks to advances in surgical techniques. Some people do need a temporary ostomy. After a short period for healing, a surgeon can reconnect the bowel so normal bathroom habits can be resumed.Back to top
Our colorectal surgeons use advanced surgical procedures, including:
- minimally invasive techniques, such as laparoscopy and robotic surgery. With these methods, surgeons can use smaller incisions (cuts) than traditional surgeries.
- nerve-preserving techniques, which focus on protecting your ability to use the bathroom normally as well as your sexual health (part of the standard of care at MSK).
- coloanal reconstruction, a procedure in which a surgeon removes the rectum and connects the upper colon directly to the anus. This option works well for people who aren’t good candidates for other techniques, such as men with large prostate glands.
- colonic reservoir, in which a surgeon loops two sections of the lower colon together and opens up the wall between them to construct an internal colon pouch. This is called a J-pouch. It creates a reservoir for storing waste and improves your ability to go to the bathroom normally after surgery to remove the rectum.
In minimally invasive surgery, doctors can use smaller incisions (cuts) than traditional surgery. These techniques can help minimize damage to nearby organs and tissues. People who have minimally invasive surgery have a lower risk of infection and less blood loss. They often recover faster. At MSK, we use the following minimally invasive methods:
- Laparoscopy. During a laproscopy, a surgeon uses a thin, lighted tube with a video camera at its tip. This tool is called a laparoscope. It is inserted through a small opening made in the abdominal wall so that the surgeon can operate using special instruments. MSK’s surgeons are helping lead national clinical trials to test this approach in rectal surgery. Early studies show that laparoscopy is safe and feasible. Currently, surgeons usually must make an incision low in the pelvis to complete the surgery.
- Robotic-assisted surgery. This type of surgery began around 2002. Doctors at MSK helped pioneer its use for colon and rectal surgery. Special instruments are inserted through keyhole-size cuts in the abdominal wall. The surgeon sits at a computer and uses controls to move robotic arms that precisely operate the surgical tools. A high-definition visual system helps the surgeon see more clearly by magnifying the operation. MSK’s surgeons perform more robot-assisted minimally invasive procedures for colon and rectal cancer than doctors at any other institution in the country. You and your doctor will decide together if it’s the best option for your treatment.
- Transanal endoscopic microsurgery (TEM). This procedure involves removing early-stage rectal cancer using a scope that’s inserted into the anus. TEM typically takes less time than standard abdominal surgery. It is ideal for older patients with medical conditions that would make longer and more complex operations difficult, or for people who don’t want a standard operation. TEM minimizes treatment-related complications, reduces recovery time, and spares the nearby nerves associated with the ability to use the bathroom normally as well as with sexual health. Most importantly, people who have TEM don’t need a colostomy. They can go home soon after the procedure. Our experienced rectal surgeons have been performing TEM since 2004.
Research shows that surgeons at centers where a high number of procedures are performed produce the best results for their patients. MSK’s surgeons are among the most experienced in the world at removing rectal cancer.
MSK is recognized around the world as a leader in treating rectal cancer. Each year we care for more than 1,200 people with colon and rectal cancer, restoring people to health after every kind of rectal cancer, including the rarest types. We will tailor a treatment specifically for you.
Many of the most-advanced techniques developed recently were first studied and used by MSK’s colorectal cancer team. The people we care for have access to clinical trials with new treatment options that may not be available at other hospitals.
We believe you should choose MSK because we offer:
- Compassionate care from a team of more than 70 colorectal cancer care specialists, nurses, and other health professionals. Our surgeons work with experts from diverse fields, including chemotherapy, radiology, pathology, and symptom management. Many of them are nationally or internationally recognized.
- The most-advanced rectal cancer treatments, including minimally invasive surgeries, which use smaller incisions (cuts) than traditional surgery.
