==Overview==
==[[Volvulus overview|Overview]]==
A '''volvulus''' is a loop of the [[bowel]] whose nose has twisted on itself.<ref>Medical Terminology Systems: A Body Systems Approach, 2005</ref> The American Heritage Stedman's Medical Dictionary defines volvulus slightly differently as "abnormal twisting of the intestine causing obstruction," which adds obstruction in the definition, and would be more clinically significant term.<ref>{{cite web | url = http://www.kmle.com/search.php?Search=volvulus | title = ''KMLE Medical Dictionary Definition of volvulus'' | author = [http://www.kmle.com The American Heritage Stedman's Medical Dictionary]}}</ref>


==Types==
==[[Volvulus historical perspective|Historical Perspective]]==
*[[Gastric volvulus]] (click on the link in blue to read more about this specific type of volvulus)
* Volvulus Neonatorum
* Volvulus Small Intestine
* Volvulus Caecum
* Volvulus Sigmoid Colon


==Causes==
==[[Volvulus classification|Classification]]==
Midgut volvulus occurs in patients (usually in infants) that are predisposed because of congenital [[intestinal malrotation]].  Segmental volvulus occurs in patients of any age, usually with a predisposition because of abnormal intestinal contents (e.g. [[Meconium|meconium ileus]]) or [[adhesions]].  Volvulus of the [[cecum]], [[transverse colon]], or [[sigmoid colon]] occurs, usually in adults, with only minor predisposing factors such as redundant (excess, inadequately supported) intestinal tissue and constipation.


==Presentation==
==[[Volvulus pathophysiology|Pathophysiology]]==
Regardless of cause, volvulus causes symptoms by two mechanisms.  One is [[bowel obstruction]], manifested as abdominal distension and vomiting.  The other is  [[ischemia]] (loss of blood flow) to the affected portion of intestine.  This causes severe pain and progressive injury to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed.<ref>Medical Terminology Systems: A Body Systems Approach, 2005</ref> Ultimately, this can result in [[necrosis]] of the affected intestinal wall, [[acidosis]], and death.  Acute volvulus therefore requires immediate surgical intervention to untwist the affected segment of bowel and possibly [[bowel resection|resect]] any unsalvageable portion.<ref>Medical Terminology Systems: A Body Systems Approach, 2005</ref>


Volvulus occurs most frequently in middle-aged and elderly men.<ref>Medical Terminology Systems: A Body Systems Approach, 2005</ref>  Volvulus can also arise as a rare complication in persons with [[Colon (anatomy)|redundant colon]], a normal anatomic variation resulting in extra colonic loops.<ref>{{cite web

Sigmoid volvulus is the most-common form of volvulus of the gastrointestinal tract and is responsible for 8% of all intestinal obstructions. Sigmoid volvulus is particularly common in elderly persons and constipated patient. Patients experience abdominal pain, distension, and absolute constipation.
