Figure 3 Comparison of different distention options in the same patient with diagnosis of adenocarcinoma. A: Distension with positive oral contrast, the double arrow shows the extent of the lesion, which is larger than b and c, thus overestimating the neoplasm size; B: Distension with effervescent granules, the double arrow shows the tumor extent which is larger than c, still overestimating its size; C: Distension with pneumo-computed tomography technique, the double arrow shows the extent of the wall thickening which is shorter than a and b in accordance with the surgical specimen.
