Where there is significant dilatation of a hollow viscus, there are limited differentials. If it were midline and lower in the abdomen we could think about sigmoid volvulus.
However, if there is associated small bowel obstruction the level of obstruction is likely to be more proximal. If there is a hugely dilated hollow viscus and accompanying small bowel obstruction, think cecal volvulus.
Cecal volvulus will often present as a large dilated loop of bowel to the left of midline as the mesentery that the cecum is suspended on twists.
Features here are of cecal volvulus with accompanying small bowel obstruction.
