SPONTANEOUS RUPTURE OF ESOPHAGUS SIMULATION METHOD Russian patent published in 2018 - IPC G09B23/28 

FIELD: medicine.

SUBSTANCE: invention refers to experimental medicine, namely to thoracic surgery, and concerns simulating of spontaneous rupture of the esophagus. Method includes cervical mediastinotomy performance, posterior mediastinal tissue penetration, esophagus mobilization along the circumference in the upper and lower directions, esophagus tube installation in the lumen, its connection with a manometer, implementation of laparotomy, creation of excessive pressure in the esophagus. In this case, the esophagus is crossed in the transverse direction at a distance of 2–3 cm from the esophageal-pharyngeal transition, and the tube is inserted into the lumen of the esophagus through the resulting aperture towards the stomach. They produce a circular mobilization of the stomach. After that, the walls of the stomach are sewn together down the cardiac socket to 3–5 cm parallel to the small curvature to form a tunnel, the front wall of which is then dissected 1.5–2.0 cm longitudinally. Introduce the tunnel in the tunnel to the distal end of the esophagus, the second tube, the outer diameter equal to the internal diameter of the esophagus. They seal the resulting compounds. Excess pressure in the esophagus is created by feeding fluid through this tube in a volume of 150–200 ml at a pressure of 0.8–1 bar.

EFFECT: method makes it possible to create a model that is acceptable for studying changes in the tissues of the esophagus, as well as for the possibility of learning the management of special medical instruments and sutures to correct the esophageal defect.
