Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post esophagectomy and gastric pull - up . The inspiratory lung volumes are decreased . Increased opacification at the bilateral lung bases on the left greater than the right may represent atelectasis in this setting . Blunting of the left costophrenic angle suggests trace left pleural fluid . Left apical opacification is stable in comparison to the prior study . There is no definitive evidence of pneumothorax . The thoracic aorta is tortuous with calcification of the aortic knob . The cardiac silhouette is incompletely evaluated in the setting of left basilar opacification that is likely stable . Surgical clips in the right upper quadrant of the abdomen are compatible with prior cholecystectomy . Surgical clips at the left hemidiaphragm and left upper quadrant may represent prior splenic surgery .
    OUTPUT:
    
1 . Decreased lung volumes with increased bibasilar opacities on the left greater than the right most likely reflecting atelectasis , although superimposed infection is not excluded in the appropriate clinical context . 2 . Stable dilation of the trachea and unchanged opacification of the left lung apex .
