Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: An endotracheal tube tip terminates approximately 5 cm from the carina . An orogastric tube tip terminates in the distal esophagus with side port in the upper / mid esophagus . There is persistent left hemithorax opacification with leftward shift of mediastinal structures indicative of left lung collapse . Probable small left pleural effusion is likely present . As noted previously there is a abrupt cut off of visualization of the distal left mainstem bronchus . Right PICC tip remains in unchanged position within the lower SVC . Remainder of the right lung is unchanged . Punctate radiopaque densities in the left upper quadrant of the abdomen likely reflect ingested material within the bowel .
    OUTPUT:
    
1 . Endotracheal tube in standard position . 2 . Orogastric tube terminates in the distal esophagus and needs to be advanced by at least 18 cm . 3 . Persistent opacification of the left hemi thorax with leftward shift of mediastinal structures indicative of left lung collapse . Probable small left pleural effusion . Abrupt cut off of the distal left mainstem bronchus suggests an endobronchial lesion such as mucous plugging .
