Sigmoid volvulus produces a characteristic bent inner tube or coffee bean appearance, with the convexity of the loop lying in the right upper quadrant opposite the site of obstruction. Gastrografin enema shows a narrowing at the site of the volvulus and a pathognomonic birds beak. Ref: Schwazs principle of surgery 9th edition, chapter 29.
