Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is free intra peritoneal air visible under the right hemidiaphragm . This is consistent with patient 's known recent laparoscopic intra-abdominal surgery . Multiple median sternotomy wires and mediastinal surgical clips are again seen in stable position . There are low lung volumes are poor inspiratory effort . Allowing for changes due to inspiratory effort differences , the cardiomediastinal silhouette is unchanged . The bilateral hila are normal . There is an increase in retrocardiac radiodensity , which likely represents left basilar atelectasis , however , in the appropriate clinical setting , pneumonia or sequela of aspiration are also considerations . There is likely right basilar atelectasis . There probably are minimal bilateral pleural effusions . There is no evidence of pulmonary vascular congestion or pulmonary edema . There are no pneumothoraces . .
    OUTPUT:
    
1 . Small amount of free intraperitoneal air consistent with known recent laparoscopy . 2 . Increased retrocardiac density , potentially representing left basilar atelectasis , or possibly sequela of aspiration or developing pneumonia . 3 . Right basilar atelectasis and probable new minimal bilateral pleural effusions .
