What is Colectomy?
Your colon, also called your large intestine, is a long tubelike organ at the end of your digestive tract. Colectomy is a surgical procedure to remove all or part of your colon. Colectomy may be necessary to treat or prevent diseases and conditions that affect your colon.
When is Colectomy needed?
Colectomy is used to treat and prevent diseases and conditions that affect the colon, such as:
- Bleeding that can’t be controlled. Severe bleeding from the colon may require surgery to remove the affected portion of the colon.
- Bowel obstruction. A blocked colon is an emergency that may require total or partial colectomy, depending on the situation.
- Colon cancer. Early-stage cancers may require only a small section of the colon to be removed during colectomy. Cancers at a later stage may require more of the colon to be removed.
- Crohn’s disease. If medications aren’t helping you, removing the affected part of your colon may offer temporary relief from signs and symptoms. Colectomy may also be an option if precancerous changes are found during a test to examine the colon (colonoscopy).
- Ulcerative colitis. Your doctor may recommend total colectomy if medications aren’t helping to control your signs and symptoms. Colectomy may also be an option if precancerous changes are found during a colonoscopy.
- Your doctor may recommend surgery to remove the affected portion of the colon if your diverticulitis recurs or if you experience complications of diverticulitis.
- Preventive surgery. If you have a very high risk of colon cancer due to the formation of multiple precancerous colon polyps, you may choose to undergo total colectomy to prevent cancer in the future. Colectomy may be an option for people with inherited genetic conditions that increase colon cancer risk, such as familial adenomatous polyposis or Lynch syndrome.
What should you know before undergoing Colectomy?
Not everyone can safely undergo colectomy. Eligibility depends on many factors such as your specific condition, medical history, and general health.
What are the complications and side effects?
Pain is common after a colectomy. You may be prescribed pain medication.
In general, complications of colectomy can include:
- Blood clots in the legs (deep vein thrombosis) and the lungs (pulmonary embolism)
- Injury to organs near your colon, such as the bladder and small intestines
- Tears in the sutures that reconnect the remaining parts of your digestive system
It is important you understand the precautions and know the possible complication and side effects before having this Colectomy. If you have any questions, please consult with your doctor or surgeon for more information.
How do I prepare for Colectomy?
During the days leading up to your colon surgery, your doctor may ask that you:
- Stop taking certain medications. Certain medications can increase your risk of complications during surgery, so your doctor may ask that you stop taking those medications before your surgery.
- Fast before your surgery. Your doctor will give you specific instructions. You may be asked to stop eating and drinking several hours to a day before your procedure.
- Drink a solution that clears your bowels. Your doctor may prescribe a laxative solution that you mix with water at home. You drink the solution over several hours, following the directions. The solution causes diarrhea to help empty your colon. Your doctor may also recommend enemas.
- Take antibiotics. In some cases, your doctor may prescribe antibiotics to suppress the bacteria found naturally in your colon and to help prevent infection.
Preparing for colectomy isn’t always possible. For instance, if you need an emergency colectomy due to bowel obstruction or bowel perforation, there may not be time to prepare.
What happens during Colectomy?
Colectomy usually takes between 1 and 4 hours.
On the day of your surgery, your health care team will take you to a preparation room. Your blood pressure and breathing will be monitored. You may receive an antibiotic medication through a vein in your arm.
You will then be taken to an operating room and positioned on a table. You’ll be given a general anesthesia medication to put you in a sleep-like state so that you won’t be aware during your operation.
The surgical team will then proceed with your colectomy. Colon surgery may be performed in two ways:
- Open colectomy. Open surgery involves making a longer incision in your abdomen to access your colon. Your surgeon uses surgical tools to free your colon from the surrounding tissue and cuts out either a portion of the colon or the entire colon.
- Laparoscopic colectomy. Laparoscopic colectomy, also called minimally invasive colectomy, involves several small incisions in your abdomen. Your surgeon passes a tiny video camera through one incision and special surgical tools through the other incisions.
The surgeon watches a video screen in the operating room as the tools are used to free the colon from the surrounding tissue. The colon is then brought out through a small incision in your abdomen. This allows the surgeon to operate on the colon outside of your body.
Once repairs are made to the colon, the surgeon reinserts the colon through the incision.
The type of operation you undergo depends on your situation and your surgeon’s expertise. Laparoscopic colectomy may reduce the pain and recovery time after surgery. But not everyone is a candidate for this procedure. Also, in some situations your operation may begin as a laparoscopic colectomy, but circumstances may force your surgical team to convert to an open colectomy.
Once the colon has been repaired or removed, your surgeon will reconnect your digestive system to allow your body to expel waste. Options may include:
- Rejoining the remaining portions of your colon. The surgeon may stitch the remaining portions of your colon together, creating what is called an anastomosis. Stool then leaves your body as before.
- Connecting your intestine to an opening created in your abdomen. The surgeon may attach your colon (colostomy) or small intestine (ileostomy) to an opening created in your abdomen. This allows waste to leave your body through the opening (stoma).
You may wear a bag on the outside of the stoma to collect stool. This can be permanent or temporary.
Connecting your small intestine to your anus. After removing both the colon and the rectum (proctocolectomy), the surgeon may use a portion of your small intestine to create a pouch that is attached to your anus (ileoanal anastomosis). This allows you to expel waste normally, though you may have several watery bowel movements each day.
As part of this procedure, you may undergo a temporary ileostomy.
Your surgeon will discuss your options with you before your operation.
What happens after Colectomy?
After surgery you’ll be taken to a recovery room to be monitored as the anesthesia wears off. Then your health care team will take you to your hospital room to continue your recovery.
You’ll stay in the hospital until you regain bowel function. This may take a couple of days to a week.
You may not be able to eat solid foods at first. You might receive liquid nutrition through a vein, often in your arm, and then transition to drinking clear liquids. As your intestines recover, you can eventually add solid foods.
If your surgery involved a colostomy or ileostomy to attach your intestine to the outside of your abdomen, you’ll meet with an ostomy nurse who will show you how to care for your stoma. The nurse will explain how to change the ostomy bag that will collect waste.
Once you leave the hospital, expect a couple of weeks of recovery at home. You may feel weak at first, but eventually your strength will return. Ask your doctor when you can expect to get back to your normal routine.
If you have any questions or concerns, please consult with your doctor or surgeon for more information.
What should you do after Colectomy?
For the first six weeks after surgery, a low residue diet is recommended, which is a low fiber diet that is designed to reduce the amount and frequency of stools and to extend the time spent digesting the food itself. This is to avoid unnecessary trauma to the healing intestinal reconnection.
It takes approximately two to three weeks to completely resume normal activities. It’s advisable to avoid heavy lifting for approximately six weeks.
