A large bowel resection, also known as a colectomy is a surgical procedure done to remove diseased or cancerous sections of your large bowel.
The large bowel is also known as the large intestine or colon.
A large bowel resection involves the removal of the diseased or cancerous parts of your bowel and then reattaching the healthy parts together. It may also involve the total removal of your entire large bowel.
In cases where the entire large bowel is removed or part of the large bowel is surgically altered, a surgical procedure known as colostomy may be performed to allow for the evacuation of stool.
Colostomy involves creating an opening on your abdominal walls and attaching a bad on the opening to collect stool. An end of your small intestine or large intestine is then connected to the opening to allow for the evacuation of stool or waste products.
Colostomy may either be temporary or permanent. If the diseased or cancerous parts of your large bowel were removed and then the healthy parts reattached, it is done temporarily to allow the surgical site to heal. However, if your entire large bowel was removed, a colostomy is done permanently for the evacuation of stool. A permanent colostomy is, however, required in very rare cases.
The purpose of large bowel resection is to remove or cut off the diseased or cancerous part of the large bowel.
Your doctor may recommend a large bowel resection if you have conditions such as:
During the procedure, you will be given general anesthesia before the surgery begins. The general anesthesia will keep you asleep and unconscious throughout the surgery.
Your surgeon may decide to perform a laparoscopic or open colectomy
If your surgeon decides to perform a laparoscopic colectomy, he or she will create tiny incisions on your abdomen. He or she will then direct a laparoscope attached with a tiny camera to view your large intestine or bowel to know the diseased or cancerous part. Your surgeon will then use certain instruments to cut off the diseased or cancerous part. The remaining healthy parts will then be attached together.
If your surgeon decides to perform an open colectomy, he or she will make a large incision to see your bowel directly. There will be no need for a laparoscope or camera. Your surgeon will then cut off the diseased or cancerous part and reattach the healthy parts. This procedure is more invasive than laparoscopic colectomy.
Your surgeon may also perform a colostomy to allow for the evacuation of stool during recovery. When completed, the incisions will be stitched.
Just like every other surgical procedure, large bowel resection surgery carries some risks. These risks include:
Colon resection is a major surgery that involves the removal of parts or the entire colon. You may need to remain in the hospital for days before going back home.
It could take about 4 weeks to recover from bowel resection surgery. The first and second week is the most critical part of recovery. During this time, you will be allowed to take only liquids to allow your bowel to heal. As the week goes by, you can then gradually transition into taking semi-solids and then solid foods in the fourth week when your bowel must have fully recovered.
Yes, you can live without your large bowel. The primary role of the large bowel or intestine is to absorb and accumulate waste products for evacuation. It plays little role in metabolism and people can live their lives without it. When the large bowel is removed, a new route is created for the evacuation of waste products or stool. A surgical procedure known as colostomy is performed for the evacuation of stool.
Though bowel resection surgery is beneficial for people with diseased or cancerous large bowel, there are certain risks and complications that can occur. Risks and complications can be greatly minimized if the surgery is performed by a highly-skilled surgeon that has performed many previous successful procedures.
Apart from the risks and complications that may occur, there have been records of a few cases of death. The mortality rate of bowel resection surgery is about 2% to 6% depending on the stage or severity of the condition.
You will be given general anesthesia to make you sleep throughout the surgery so that you don’t feel pain. After the surgery and when the effect of the anesthesia has worn off, you may start to feel pain. You may be given pain medications that you will be taking to help relieve pain. The pain may come and go for the next few days after the surgery. You will likely feel better in a week or 2-weeks time.
Your surgeon may perform a colostomy to allow for the evacuation of stool until you recover. If this is not needed, your surgeon may recommend taking fiber for constipation with a large volume of water to soften your stool for easy passage.
You may feel pain and irregular bowel movements for days to a few weeks. You may need to stay in the hospital for about 2 to seven days so that your doctor can monitor you. You may also see blood in your stool. During the first few days, you will be allowed to only drink liquids.
You will probably be back to normal in 2-4 weeks. Do not engage in strenuous activities or lift heavy objects during your recovery. You can take some walks and engage in regular less-strenuous activities. You will be given instructions on how to care for your wound.
A colon resection surgery could take up to 4 hours to be completed.
After a bowel resection surgery, you will need to take only liquids in the first few days. You will gradually transition into eating soft foods that are easy to swallow and digest.
You will need to avoid foods that are difficult to digest. The foods that you should avoid include tough meats, bread, nuts, seeds, chunky peanut butter, undercooked meats, uncooked fish, fried foods, fast foods, beans, peas, hot dogs, sausage, strong-flavored cheeses, coconut, raisins, and desserts with nuts.
