title: [Measurement of gastric emptying with Xianshizi in patients with resected esophageal cancer].
abstract: OBJECTIVE
  To determine gastric emptying radiological in patients with esophageal cancer and to obtain a similar effect produced by radionuclide study.
  
  
  METHODS
  A new product-Xianshizi (XSZ) made of the mixture of barium and silica gel was used quantitatively to evaluate gastric emptying. 17 patients with resected esophageal cancer before and after operation, and 7 healthy volunteers were studied.
  
  
  RESULTS
  Preoperative patients had obviously delayed gastric emptying compared with the control group (P < 0.01). Postoperative patients had more delayed gastric emptying compared with themselves (P < 0.05).
  
  
  CONCLUSIONS
  Postoperative gastroparesis is related to delayed gastric emptying. The results of this study were identical with those obtained by scintigraphy. Compared with isotope studies, X-ray exam after taking meal composed of XSZ may eventually contribute to detecting delayed gastric emptying quantitatively.
