Vertical banded gastroplasty complicated with pouch dilatation and stenosis of the connecting stoma. 3D volume rendered image (a) demonstrates the anatomical changes including intact vertical stapling line with pouch dilatation and tight band around stoma exerting stenosis. Pouch dilatation is evident in gastric volumetry image (b) coded with blue color, its volume = 76.7 ml. MIP image (c) demonstrates intact radiodense vertical stapling line, narrowed stoma with filling defects within the dilated pouch mostly representing retained food particles. Normal appearing gastric stoma from another with the same procedure is demonstrated in (d) for comparison
