A redundant colon is an abnormally long colon that cannot fit inside the body without looping or twisting. There is no obvious cause, but it can lead to complications and gastrointestinal problems, including constipation.
The colon is part of the digestive system. It is the longest part of the large intestine and connects the small intestine to the anus.
The colon removes some electrolytes, nutrients, and water from partially digested food and passes the remaining solid waste — stool. The rectum stores stool, which exits through the anus.
Doctors refer to the colon as redundant if it is abnormally long.
In this article, we look at what a redundant colon is, its signs and symptoms, causes, when to seek help, diagnosis, and treatment. We also look at home care remedies and the outlook for those with the condition.
A redundant colon is an abnormally long, tortuous colon that twists and loops to fit inside the body. It can affect the entire colon, but it
Signs and symptoms may include:
Experts do not know what causes a redundant colon. Part of what
A redundant colon is a congenital condition, which means it is something a person is born with rather than something that develops over time due to external factors.
A person may be unaware that they have a redundant colon, as they may be asymptomatic. However, the condition can have serious implications and may lead to severe digestive, urinary, or vascular complications.
A person should see a doctor if they:
It can be difficult for doctors to diagnose a redundant colon using endoscopic methods. The looping of the colon can make it difficult for doctors to use imaging instruments.
Other procedures doctors may use include:
A sigmoidoscopy is a procedure in which a doctor
Due to the looping of the sigmoid colon that is often present in a redundant colon, a doctor may not be able to effectively maneuver the tube or see the inside of the sigmoid.
A colonoscopy is similar to a sigmoidoscopy, except the doctor may examine the entire colon. While a doctor may have difficulty examining the redundant colon, a colonoscopy can help to identify the condition, as it can reveal the twists and loops that
A redundant colon can be a medical emergency that requires immediate attention. Treatments
Decompression of the sigmoid volvulus
During this procedure, a doctor inserts a soft tube into the rectum and maneuvers it into the obstructed loop with the guidance of a sigmoidoscope.
If patients cannot undergo decompression or their condition has progressed significantly, they may require surgery. Surgeons typically perform a sigmoid colectomy with either a primary anastomosis or an end colostomy.
- Sigmoid colectomy: In this procedure, surgeons remove a piece of the bowel. They will make an incision in the abdomen, remove the affected length of the colon, and then join the remaining ends of the bowel by stapling or stitching them.
- Primary anastomosis: This procedure involves surgeons joining two parts of the colon after removing the affected length.
- End colostomy: Instead of joining the open ends of the colon together, the surgeon may pull the end of the colon out through an incision in the abdomen and stitch it to the skin to create a stoma. The stoma removes waste into a colostomy bag outside of the body. A colostomy can be temporary or permanent.
A person with a redundant colon may experience frequent constipation. They can treat and avoid constipation by:
A person may have a completely asymptomatic redundant colon, which they can live with without a problem. However, if symptoms do occur, they may signal a severe medical complication.
For symptomatic people, sigmoidoscopic decompression is highly successful and effective in 40–90% of cases. If a patient requires surgery due to sigmoid volvulus, there is a high likelihood of success. However, a person
A redundant colon is an abnormally long colon that twists and loops to fit into the body. A person can be born with the condition, but experts are not sure of the exact causes.
Doctors may have difficulty maneuvering imaging equipment, such as a sigmoidoscope, inside a redundant colon. However, a colonoscopy or CT scan may help a doctor identify loops and curves, which can help diagnose.
A redundant colon can lead to severe complications. If a person experiences symptoms, they may require medical intervention. Treatments include decompression of the sigmoid volvulus, which allows gas and feces to move through the obstructed area and clear it, or surgery to remove a piece of the colon.
