Total colectomy is the complete surgical removal of the colon. Colectomy is used when medications cannot treat colon disease.
Ileoanal reservoir or anastomosis is a surgical procedure to eliminate waste after completely removing the large intestine (colon and rectum) and protecting the anal sphincter. These procedures help treat conditions, such as ulcerative colitis and familial polyposis that increase the high risk of colon and rectal cancers.
How are total colectomy and ileoanal reservoirs done?
The total colectomy and ileoanal reservoirs are performed under general anesthesia in two steps.
- The surgeon first makes three to five small cuts (incisions) in the abdomen before removing the large intestine. Then, the surgeon removes the rectum, leaving the anal sphincter and anus in place. (Anal sphincter is a muscle that helps open the anus during a bowel movement.)
- The surgeon will sew a pouch from the last 12 inches of the small intestine to the anus.
Some surgeons may use a laparoscope to perform the surgery. It requires minimal surgical cuts, which has advantages, such as faster recovery and less pain. A laparoscope is a camera-aided surgical procedure.
What are the risks of anesthesia and total colectomy and ileoanal reservoirs?
The risks of anesthesia and surgery include:
What precautions to take before and after total colectomy and ileoanal reservoirs?
- Two weeks before the surgery, stopping a few medications, such as blood thinners, is recommended.
- To stop smoking before the surgery, take your doctor’s help.
- Inform your doctor about cold, flu or herpes break out, or any illness before the surgery.
- One day before surgery, you could be asked to stay on fluids. Enemas and laxatives are used to clear the intestines.
You may have to stay in the hospital for five to seven days after surgery.
- From the second day, you may be able to drink clear liquids, once the bowel starts functioning. You may have thicker fluids and a soft diet later with more recovery.
- A bland diet, dairy, and cooked vegetables should be included to avoid ulcers, nausea, vomiting, gastroesophageal reflux disease, and heartburn.
Most children and adults report an improvement in their quality of life. Incontinence affects older people; they may need to use the bathroom more frequently, especially at night. Most people have four to six bowel movements per day and one at night on average.

10 Natural Remedies for Colon CleansingA colon cleanse is the act of flushing out or cleaning the large intestine. They may be performed by professionals called colonic hygienists. In spite of insufficient research to support its benefits, the goal of colon cleansing is to clear the colon of any stagnant, supposedly toxic waste encrusted on the walls of the large intestine.
Cologuard Test vs ColonoscopyCologuard is the recently Food and Drug Administration (FDA)-approved stool deoxyribonucleic acid (DNA) screening test for detecting colon cancer. The Colorguard test is different from a colonoscopy because you can do it at home and you do not need to prepare by fasting or discontinuing medications before or after the test.
Colon Cancer (Colorectal Cancer)Colon Cancer (Colorectal Cancer) is a malignancy that arises from the inner lining of the colon. Most, if not all, of these cancers, develop from colonic polyps. Removal of these precancerous polyps can prevent colon cancer.
Colon Cancer: How Your Food and Diet Can Affect Colorectal Cancer HealthDiet, including nutrient, antioxidant, and vitamin intake, affects colon cancer risk. Certain dietary factors either decrease or increase the risk of colorectal cancer, breast cancer, and other diseases. Dietary factors may either inhibit or stimulate the development of cancer cells. Have a nutrition plan that decreases the risk.
Colon Cancer IllustrationsMost, if not all, of these cancers develop from colonic polyps. Removal of these precancerous polyps can prevent colon cancer. See a picture of Colon Cancer and learn more about the health topic.
Colon and Colorectal Cancer ScreeningColon cancer is preventable by removing precancerous colon polyps, and it is curable if early cancer is surgically removed before cancer spreads to other parts of the body. Therefore, if screening and surveillance programs were practiced universally, there would be a major reduction in the incidence and mortality of colorectal cancer.
Colon PolypsColon polyps are fleshy growths inside the colon lining that may become cancerous. Symptoms include rectal bleeding. Learn about causes, signs, treatment, and how to prevent colon cancer.

How Long Before a Colonoscopy Should I Stop Drinking Water?A colonoscopy is a test to look at the inside of the colon. Usually, doctors recommend patients undergoing a colonoscopy to stop drinking clear liquid or water at least three to four hours before the procedure. However, patients with diabetes and who are dehydrated may take a few sips of water after consulting their doctor.
Is A Colon Resection A Major Surgery?Colon resection (colectomy) is the surgical removal of part or the entire colon. Colectomy is a major surgery and may take up to four hours for completion. Colectomy is performed under general anesthesia and may require hospitalization for up to a week or more.
Sigmoidoscopy vs. ColonoscopyBoth sigmoidoscopy and colonoscopy are nonsurgical procedures that involve use of a tube (endoscope) with a light and camera to examine parts of the large intestine (colon). A sigmoidoscopy is a procedure in which a fiberoptic camera is used to examine the rectum and lower part of the colon. The difference between a sigmoidoscopy and colonoscopy is that a colonoscopy examines the upper part of the colon as well.
Virtual ColonoscopyVirtual colonoscopy is a procedure that uses a CT scan to construct virtual images of the colon. Virtual colonoscopy takes approximately 10 minutes, and in comparison to traditional colonoscopy is less invasive and requires no conscious sedation. Virtual colonoscopy may not be recommended for some patients due to their medical history.
Where Is Colon Cancer Pain Felt?Colon cancer is cancer of the last part of the large intestine. Colon cancer pain is generally felt as vague abdominal pain or cramps.
