Analysis of the movement of food bolus: a comparison between a healthy esophagus and a chagasic megaesophagus

Conclusion: Chagas disease generates a velocity close to zero and a high dampering in the downwards curve of the bolus whose displacement cannot return to its initial state, due to aperistalses, which proves the food bolus retention. With the introduction of the proposed organic control system, an approximation of the curves that remained with dynamic behavior close to the model of the healthy organ was obtained, minimizing the retention of the food.
