Tracheophishoprine fistula

Tracheophistinal fistula. Its origin is associated with an incorrect division of the so-called primary gut in the stage of embryogenesis into the respiratory and esophageal tubes. The fistula is located, as a rule, high - at level 1 of the thoracic vertebra.

The clinical symptomatology depends on the diameter of the fistula. In connection with the throwing of food from the esophagus into the respiratory tract, there are attacks of cough and cyanosis at the time of feeding the baby, especially in the horizontal position. The diagnosis is established by bronchoscopic examination. The fistula is located on the posterolateral surface of the trachea, somewhat higher than the bifurcation. At the time of the study, you can use the introduction of 1% methylene blue solution into the esophagus, which in the presence of fistula enters the lumen of the trachea. A contrast study of the esophagus with water-soluble contrast agents in prone position is also used. However, the absence of contrasting trachea does not exclude the presence of fistula.

Treatment only operative: allocation, dressing and crossing of the fistula. During the diagnosis, preoperative preparation and after the operation for several days, the baby is fed through the probe and creates a constantly elevated position, treating aspiration pneumonia. The prognosis is favorable.
