The stomach tube is a slender tube used for drainage and decompression of the upper digestive tract, and is commonly used after esophagus, cardia and stomach operations to prevent stomach storage, reduce tension of anastomotic stoma and reduce the probability of anastomotic fistula. However, once an anastomotic fistula occurs, the traditional gastric tube cannot block the anastomotic fistula, and has no functions of resisting reflux and preventing anastomotic stenosis. The existing esophagus expansion air bag only has the functions of expanding esophagus or anastomotic stoma stenosis and does not have the functions of resisting reflux, preventing anastomotic stenosis, preventing anastomotic fistula and blocking anastomotic fistula. On the other hand, the existing esophageal stent is made of metal and can be used for plugging some intrathoracic gastroesophageal anastomotic fistula, but the esophageal stent has large damage to the anastomotic fistula and the esophagus due to hard texture, so that the growth of esophageal granulation tissues is stimulated, and the stent is wrapped by the regenerated granulation tissues and cannot be taken out; and the esophageal stent is easy to displace, so that the plugging effect is poor, and the patient is caused with strong discomfort, so that the metallic esophageal stent is not suitable for fistula at special parts such as neck.
