It 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.
It is completely surrounded by peritoneum, which forms a mesentery (sigmoid mesocolon), which diminishes in length from the center toward the ends of the loop, where it disappears, so that the loop is fixed at its junctions with the iliac colon and rectum, but enjoys a considerable range of movement in its central portion.
Behind the sigmoid colon are the external iliac vessels, the left Piriformis, and left sacral plexus of nerves.

In mammals, it consists of the ascending colon, transverse colon, the descending colon, and the sigmoid colon.
The transverse colon is the part of the colon from the hepatic flexure (the turn of the colon by the liver) to the splenic flexure (the turn of the colon by the spleen).
The walls of the sigmoid colon are muscular, and contract to increase the pressure inside the colon, causing the stool to move into the rectum.

 eMedicine - Sigmoid Volvulus : Article Excerpt by: Ali Nawaz Khan, MBBS, LRCP, FRCS, FRCP, FRCR
Background: Sigmoid volvulus is the most common form of volvulus of the gastrointestinal tract and is responsible for 8% of all intestinal obstructions.
Pathophysiology: An unusually narrow attachment of the root of the sigmoid mesentery to the posterior abdominal wall permits close approximation of the 2 limbs of the sigmoid colon.
Sigmoid volvulus is common in elderly persons, in individuals with neurologic conditions, and in patients in nursing homes or mental health facilities.

 ACS :: What Is Colorectal Cancer?
The colon continues to absorb water and mineral nutrients from the food matter and serves as a storage place for waste matter.
The second section is called the transverse colon since it goes across the body from the right to the left side in the upper abdomen.
At its end, the sigmoid colon joins the rectum, which in turn joins the anus, or the opening where waste matter, or stool, passes out of the body.

 Sigmoid diverticulosis - colon clense hydrotherapy enema clensing
Sigmoid diverticulosis is the occurrence of a large amount of diverticulums in the colon.
The condition of sigmoid diverticulosis is when in the colon area - mainly in the sigmoid where there is a higher pressure - small "balloon" like bursts in the intestinal wall are formed along the naturally weaker spots.
Using regular colon clense is a good way to avoid developing this condition..

 Survival benefit of high ligation of the inferior mesenteric artery in sigmoid colon or rectal cancer surgery.
BACKGROUND: The aim of this study was to assess the impact of inferior mesenteric artery (IMA) root nodal dissection before high ligation of the artery on survival in patients with sigmoid colon or rectal cancer.
METHODS: Data on 1188 consecutive patients who underwent resection for sigmoid colon or rectal cancer, with high ligation of the IMA, were identified from a prospective database (April 1965 to December 1999).
CONCLUSION: High ligation of the IMA allows curative resection and long-term survival in patients with cancer of the sigmoid colon or rectum and nodal metastases at the origin of the IMA.

The result of this study suggests that resection of acute sigmoid volvulus and primary anastomosis after antegrade intraoperative colonic lavage is safe provided the patient is reasonably fit.
In the developed world, sigmoid volvulus is responsible for 5% of large bowel obstructions and occurs in elderly and frail patients with intercurrent medical illnesses.
The diagnosis of sigmoid volvulus was made from the history of a large bowel obstruction (constipation, abdominal distension and abdominal pain), which was often recurrent, and the plain abdominal radiographs in 16 patients.

The sigmoid colon is most susceptible to diverticula (again probably relating to the fact that the stool would be hardest in the most terminal parts of the colon).
Since the blood vessels of the colon travel in its mesentery, they could certainly be impinged in a volvulus.
A sigmoid volvulus would affect the sigmoid branches of the inferior mesenteric, while a volvulus of the cecum could affect the ileocolic and/or appendicular branches of the superior mesenteric artery.

 Re: Laparoscopic Repair of a Perforated Sigmoid Colon - UnicorMed Forums
One of the appendix epiploicae was carefully disected away from the wall of the colon using the hook electrocautery.
Another physician performed flexible sigmoidoscopy and while occluding the colon proximal to the repair, the colon and rectum were insufflated gently with air in order to test the repair for a leak.
The area of repair in the sigmoid colon was again examined, and it appeared to be intact.
