Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: History for prior chest x-ray indicates the patient is status post esophagectomy and gastric pull - through . Rotated positioning . ET tube tip lies 8 cm above the carina at the level of the midclavicular heads . This lies relatively high and advancement clinical correlation regarding advancement is requested . An orogastric type tube extends to the right and mediastinum , beneath the diaphragm off the film . An additional linear density follows the same course . Again seen is the left subclavian central line does not cross the midline to the SVC . Rather , the tip projects over the distal left brachiocephalic vein , similar to prior . No well - defined pneumothorax is identified . There remains subtle lucency at the left base laterally and along the medial aspect of the left lung near the aortic knob which could represent some residual loculated pneumothorax . Again seen is the left chest tube with the sideport very slightly retracted compared to prior film , now all straddling the outer cortex of the chest wall . Retrocardiac density , opacity at the right base , pleural fluid and / or thickening along the upper right chest wall are all similar and some hazy opacity in the left mid zone are all similar to the prior study . Extensive subcutaneous emphysema is also similar to the prior study . Mediastinal clips again noted . Previously seen contrast in the neo esophagus has passed .
    OUTPUT:
    
Lines and tubes as described . - Of note , the left chest tube has probably retracted very slightly compare with the prior film , such that it s side - port straddles the outer left chest wall . - In addition , as before , the left subclavian central line does not cross the midline to reach the SVC . - ET tube lies 8 cm above the carina at the level of midclavicular heads . Clinical correlation regarding possible advancement is requested . Extensive subcutaneous emphysema . Areas of lucency in the left lung adjacent to the aortic knob and at the base of the left lung could represent residual pneumothoraces , but are less distinct on today 's exam . Other bilateral areas of opacity are similar to the prior study . The presence or absence of CHF and the infectious consolidations would be difficult to exclude in this setting .
