Regardless of cause,<unk>  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. Ultimately, this can result in necrosis of the affected intestinal wall, acidosis, and death. Acute<unk>  therefore requires immediate surgical intervention to untwist the affected segment of bowel and possibly resect any unsalvageable portion.
