Volvulus causes severe pain and progressive injury to the intestinal wall, with accumulation of gas and fluid in the portion of the bowel obstructed. [11] Ultimately, this can result in necrosis of the affected intestinal wall, acidosis, and death. This is known as a closed-loop obstruction because there exists an isolated ("closed") loop of bowel.
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. [2] [5] Either the small bowel or large bowel may be affected. [1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. [1]
Around the base of the narrow sigmoid colon, the empty loops of the ileum and distal jejunum rotate in a clockwise direction. With two closed-loop obstructions—one in the small bowel and the other in the sigmoid colon—further peristalsis creates an ileosigmoid knot. [6]
If a loop of bowel passes through the mesenteric defect, that loop is at risk for incarceration, strangulation, or for becoming the lead point of a small bowel obstruction. [1] Internal hernias can also trap adipose tissue (fat) and nerves. Unlike more common forms of hernias, the trapped tissue protrudes inward, rather than outward. [2]

Blind loop syndrome, also known as stagnant loop syndrome, [1] is a state that occurs when the normal bacterial flora of the small intestine proliferates to numbers that cause significant derangement to the normal physiological processes of digestion and absorption.
Lisa Marie Presley, the only child of rock 'n' roll icon Elvis Presley, died of small bowel obstruction, the Los Angeles County medical examiner's office ruled.
An antecolic afferent loop's redundancy increases the danger of kinking, volvulus, and adhesion-induced limb entrapment when the bowel length exceeds 30 to 40 cm. Conversely, the risk of an internal herniation developing in a retrocolic afferent loop is increased by incorrectly closed mesocolic abnormalities. [12]
