Sigmoid colon Sigmoid colon. The sigmoid colon (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 in length. The loop is typically shaped like a Greek letter sigma (ς) or Latin letter S (thus sigma + -oid).

Sigmoid colon See Article History. Sigmoid colon, a terminal section of the large intestine that connects the descending colon to the rectum; its function is to store fecal wastes until they are ready to leave the body. The sigmoid colon derives its name from the fact that it is curved in the form of an S (Greek sigma: σ). Its size depends upon the amount of waste material in it, but when contracted its diameter is only about one inch (2.5 centimetres). The internal surface of the sigmoid colon is similar to that of the rest of the large intestine. The smooth mucous membrane lining secretes mucus and enzymes, and the lining’s surface cells can absorb fluids. Most of these activities occur, however, higher up in the intestinal tract.

Sigmoidoscopy Flexible sigmoidoscopy enables the physician to look at the inside of the large intestine from the rectum through the last part of the colon, called the sigmoid. Physicians may use the procedure to find the cause of diarrhea, abdominal pain, or constipation.

- Melanosis coli and pedunculated polyp of the sigmoid. This 52 year-old female, for two years, had been using aloe vera capsules for constipation. A complete colonoscopy to the terminal ilium was performed. Two polyps was detected, one in the iliocecal valve and the other in the sigmoid.

Human Physiology/Print Version Sigmoidoscopy is also used to screen for colorectal cancer, the second leading cause of cancer deaths in the U.S. A short, flexible, lighted tube, called a sigmoidoscope, is inserted into the intestine through the rectum into the lower part of the large intestine.everal procedures may be used to examine different portions of the large intestine. These include a colonoscopy (examination of the entire length of the large intestine), proctoscopy (examination of the anus and rectum), and anoscopy (examination of the anus only).

Large intestine A sigmoidoscopy allows an examination of the distal portion (about 600 mm) of the colon, which may be sufficient because benefits to cancer survival of colonoscopy have been limited to the detection of lesions in the distal portion of the colon.

Large intestine The large intestine, also called the colon or the large bowel, is the last part of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation. Terminologia Anatomica, Medscape, and Gray's Anatomy define the large intestine as the combination of the cecum, colon, rectum, and anal canal.

Sigmoid Colon The sigmoid colon is a hollow tube approximately 2 ½ inches (7 cm) in diameter and 16 inches (40 cm) long. A band of smooth muscle tissue running the length of the colon contracts to form many small pouches called haustra in the walls of the sigmoid colon....

Sigmoid Colon 1 Contraction of smooth muscle tissue both forms the haustra of the sigmoid colon and propels feces out of the sigmoid colon and into the rectum during defecation.  The outermost layer of the sigmoid colon is covered by the serosa layer, which extends as a thin membrane known as the mesentery.

Top 30 Doctor insights on: Thickening Of The Sigmoid Colon 1 doctor shared a insight. The colon is another term for the large intestine. This is the final portion of the digestive system, responsible for absorbing water and storing stool before evacuation. It is divided into sections described as cecum; ascending, transverse, descending and sigmoid colons; and rectum.

Picture of the Colon • The sigmoid colon is a short curving of the colon, just before the rectum. The colon removes water, salt, and some nutrients forming stool. Muscles line the colon's walls, squeezing its contents along. Billions of bacteria coat the colon and its contents, living in a healthy balance with the body.he colon is also called the large intestine. The ileum (last part of the small intestine) connects to the cecum (first part of the colon) in the lower right abdomen. The rest of the colon is divided into four parts:

What is a Descending Colon? The descending colon is part of the large intestine. The large intestine includes the vermiform appendix, the cecum and the colon. The descending colon is part of the colon, which is made up of several parts. They include the ascending colon, hepatic flexure, transverse colon, splenic flexure, descending colon, and sigmoid colon. This part of the colon passes down through the upper back portion of the abdomen and along the side of the left kidney.

- The sigmoid colon is a curved, S-shaped region of the large intestine and is the final segment of the colon. It transports fecal matter from the descending colon to the rectum and anus. Feces are stored in the sigmoid colon until they are ready to be eliminated from the body through the anal canal.

Sigmoidectomy surgery for inflammatory bowel disease (IBD) Sigmoidectomy surgery for inflammatory bowel disease (IBD) Sigmoidectomy surgery removes all or part of the sigmoid colon - the S-shaped part of the large intestine just before the rectum. Where possible the two healthy ends of the intestinal tract are then rejoined. If this is not possible then a stoma may be formed.

Mapping the body: the sigmoid colon Inflammatory bowel disease such as ulcerative colitis and Crohn's disease may occur here. Diverticulitis, in which little outpouchings of bowel form and become inflamed, is more common in the sigmoid than any other part of the bowel. Small growths called polyps, as well as cancers, also favour this site. The good thing about investigating sigmoid disease is that this part of the colon isn't far from the outside world. It is easy to pass a rigid sigmoidoscope into the anus and get a decent view.

Gross Anatomy The colon is a 5-6–ft long, inverted, U-shaped part of the large intestine (lower gastrointestinal tract). By definition, the cecum (and appendix) and ano-rectum, which are parts of the large intestine, are not included in the colon. Embryologically, the colon develops partly from the midgut (ascending colon to proximal transverse colon) and partly from the hind gut (distal transverse colon to sigmoid colon).

- 1 The large intestine is made up of the cecum, ascending colon, transverse colon, descending colon, sigmoid colon, appendix, rectum, and anal canal.  The large intestine contains all of the colon, but the colon does not contain the cecum, appendix, rectum, or anal canal.
