1 A Flow Visualization Model of Gastric Emptying in the Intrathoracic Stomach After Esophagectomy 
Jae-Ik Lee, MD, PhD, Sunghoon Choi, MS, Jaeyong Sung, PhD  The Annals of Thoracic Surgery  Volume 91, Issue 4, Pages (April 2011) DOI: /j.athoracsur Copyright © 2011 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Averaging the course of the gastric tube. Bold lines represent the average of centroids (x, y) of 5 gastric tubes according to the vertical position (z). (A) x; (B) y.

3 Fig 2 (A) Virtual three-dimensional design of the gastric tube model. (B) Tube models with 3 diameters of 20, 40, and 60 mm. (C) Two types of pylorus model that has pyloric opening of the diameters of 7.5 and 15 mm.
