What is a sigmoid colon?

The sigmoid colon is the terminal portion of the large intestine before reaching the rectum. It connects the descending colon with the rectum. The sigmoid colon derives its name from a Greek letter sigma.

Can the sigmoid colon be removed?

Is sigmoid colon cancer curable?

Cancer of the colon is a highly treatable and often curable disease when localized to the bowel. Surgery is the primary form of treatment and results in cure in approximately 50% of the patients. Recurrence following surgery is a major problem and is often the ultimate cause of death.

What does proximal mean in anatomy?

Proximal means nearer to the center (trunk of the body) or to the point of attachment to the body. If another reference point is given, such as the heart, the proximal point of another organ or extremity is the point closest to the heart, central rather than peripheral. Proximal is the opposite of distal.

How much of your colon can be removed?

Usually, about one-fourth to one-third of the colon is removed, depending on the size and location of the cancer. The remaining sections of colon are then reattached. At least 12 nearby lymph nodes are also removed so they can be checked for cancer. If all of the colon is removed, it’s called a total colectomy.

Can sigmoid colon be removed?

Removal of the colon is called a colectomy. The remaining bowel is then joined together. Joining the bowel is called an anastomosis. When cancer is found in the sigmoid colon, the sigmoid colon is removed.

Why would the sigmoid colon be removed?

Surgeons perform colectomy to remove colon tissue that doesn’t work correctly. Many problems can stop the colon from working as it should, including: Inflamed tissues due to conditions such as inflammatory bowel disease or diverticulitis. Infection caused by a cut or hole in the colon wall.

What are the side effects of sigmoid colon removal?

Side effects of sigmoid colon removal include: Irregular bowel movements. Gas and flatulence. Diarrhea. Bladder complications. Complications in or around the stoma . These can occur early after surgery to many years after the procedure. They include skin infection or breakdown, hernias, narrowing of the stoma, bleeding, and collapse.

Is the sigmoid colon large or small?

The sigmoid colon (or pelvic colon) is the part of the large intestine that is closest to the rectum and anus. It forms a loop that averages about 35–40 cm (13.78-15.75 in) in length. The loop is typically shaped like a Greek letter sigma (ς) or Latin letter S (thus sigma + -oid).

What side is sigmoid colon?

Descending colon is that part of the colon which moves down to the spleen. Sigmoid or pelvic colon is the section of the colon which moves to the left side of the abdomen and reaches the pelvis.

What is the location of the sigmoid colon?

The sigmoid colon begins at the superior aperture of the lesser pelvis, where it is continuous with the iliac colon, and passes transversely across the front of the sacrum to the right side of the pelvis. (The name sigmoid aptly means S-shaped.)
