Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lordotic positioning . Low inspiratory volumes . Dobhoff type tube is present --___ tip is seen in the mid abdomen . It follows an atypical course in that date curves back on itself . I suspect that it has passed into the duodenum , but has not passed beyond the ligament of Treitz . The significance of the curvature of the distal tip of the tube is uncertain . Continuing surveillance is recommended . The cardiomediastinal silhouette is unchanged . There is upper zone redistribution and bibasilar atelectasis , similar to the prior film and likely accentuated by low lung volumes .
    OUTPUT:
    
Dobhoff tube likely in duodenum , but not beyond the ligament of Treitz . The significance of the curvature of the distal tip of the tube is uncertain . Continuing surveillance hand , if clinically indicated , repositioning is recommended .
