    INPUT: Patient is status post gastrectomy and esophagojejunostomy , with anastomosis likely at the level of the diaphragm on review of the prior CT . The lungs are mostly clear . The heart size is within normal limits . The mediastinum and hilar contours are unremarkable . There is no evidence for pulmonary edema , pulmonary consolidation , pleural effusion or pneumothorax . The tip of the nasogastric tube is difficult to ascertain , and possibly terminates in the lower chest or below the diaphragm . Dense radiopaque material in the shape of bowel loops is seen in the left upper quadrant and midline , likely from prior barium enema .
    OUTPUT:
    
Nasogastric tube can be traced to the lower esophagus but the tip is indistinct and can not be localized . Repeat imaging with conventional radiograph for further evaluation is recommended prior to use .
