Description
Technical Field
The invention relates to a medical auxiliary instrument, in particular to an esophageal and gastric anastomotic stoma fistula plugging and drainage device.
Background
Esophageal gastrostomy fistula is a serious complication after thoraco-esophageal radical surgery, and seriously affects the life quality and the life cycle of patients. Investigation shows that the incidence rate of the neck anastomosis fistula is about 9%, the incidence rate of the intrathoracic anastomosis fistula is about 5%, and the death rate of the anastomosis fistula is as high as 50-70%. After the patient has an esophageal-gastric anastomotic stoma fistula, saliva and gastric contents continuously overflow from the stoma to the thoracic cavity or the mediastinum, so that infection of the thoracic cavity or the mediastinum is not cured for a long time, and organism infection and consumption seriously threaten the life of the patient.
At present, three methods of conservative treatment, surgical treatment and interventional treatment are mainly adopted as the treatment method of the esophageal and gastric anastomosis fistula. The conservative treatment often has insufficient drainage, malnutrition and poor curative effect; the secondary surgery is large in wound and high in risk, and many patients are difficult to tolerate and accept; the interventional therapy is micro-traumatic, low in cost, good in curative effect and easy to accept and endure by patients. However, no medical apparatus is specially used for plugging fistulae and draining pus at present, and during treatment, the fistulae are plugged by a bracket by embedding an esophageal stent in an esophagus, and then drainage and flushing treatment are carried out on the chest pus or the pus in the mediastinum. Because the esophageal stent is arranged in the esophagus, the foreign body sensation is strong; the stent is easy to shift, and the fistula is not tightly plugged, so that the treatment effect is affected; and the stent must be removed in a short time (two months) or else restenosis of the esophagus is liable to develop, further increasing the risk of the patient.
