    INPUT: A weighted feeding tube is again seen within the stomach , with interval removal of the previously placed guide wire . Surgical ___ are seen behind the stomach shadow . The cardiac and mediastinal silhouettes are within normal limits , aside from some mediastinal clips and sternotomy sutures suggesting prior CABG . There is no focal pulmonary opacity , pleural effusion , or evidence of pneumothorax . Minimal linear opacity seen in the left lung base probably represents linear atelectasis . Osseous structures are grossly unremarkable .
    OUTPUT:
    
Post - surgical changes without evidence of pneumonia .
