http://en.wikipedia.org/wiki/Volvulus
Volvulus (twisted intestines) *, also known as mesenteric volvulus, is a rare condition in dogs. German Shepherd Dogs are predisposed. Factors that predispose dogs to this condition are intestinal foreign bodies, intestinal cancer,
Presentation
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.
Volvulus causes severe pain and progressive injury to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed.[2] 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 resect any unsalvageable portion.[2]
Volvulus occurs most frequently in middle-aged and elderly men.[2] Volvulus can also arise as a rare complication in persons with redundant colon, a normal anatomic variation resulting in extra colonic loops.[3]
Sigmoid volvulus is the most-common form of volvulus of the gastrointestinal tract[4] and is responsible for 8% of all intestinal obstructions.[citation needed] Sigmoid volvulus is particularly common in elderly persons and constipated patients. Patients experience abdominal pain, distension, and absolute constipation.

Volvulus is a secondary to bloat. The distension of the stomach from air, gastric secretions, gas and food can cause a rotation of the stomach. Never heard of cancer causing this, or forign bodies, as it usually occurs with bloat. Large deep chests,stretching of gastric ligaments, excercise after eating or drinking, splenic engorgement, and hereditary predisposition. Gastric distension(bloat) precedes gastric vovulus. The stomach distension leads to impairment of the portal venous and vena caval blood flow, and hypertension, due to obstruction by the stomach. Obviously this is an emergency!
