Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The repositioned NG tube has been advanced , now with tip projecting over the expected region of the stomach above the diaphragm , corresponding to known hiatal hernia . The stomach / hernia appears distended with gas and layering fluid . A right subclavian line ends in the low SVC , unchanged . Increased opacity in the left lower lobe likely reflects persistent atelectasis . No new focal consolidation , large effusion , or pneumothorax . Streaky linear opacities in the right lower lung are likely atelectasis . Surgical clips are seen in the right neck .
    OUTPUT:
    
1 . Repositioned NG tube tip appears to project over the expected region of the large hiatal hernia above the left hemidiaphragm . 2 . Persistent lateral lower lung atelectasis , more prominent on the left .
