FIELD: medicine.
SUBSTANCE: bronchial stump is formed by adventitia and esophagus wall muscular layer pickup with an atraumatic needle. Nodal joints are imposed. The needle is pricked in and out along the esophageal wall at a distance of 0.5 cm. Then it is pricked in the membranous part of the bronchus and pricked out in its cartilaginous part, 0.3 cm apart from the place of their connection. Ligature is not tied. Subsequent sustures are applied similarly, at a distance of 0.3 cm. Then the nodes are tightened, starting with the ligature, which is located closer to the middle of the bronchial stump cross-section. The stump is immersed in liquid, and air pressure is fed into it for leak testing.
EFFECT: decreased frequency of bronchial stump failure, due to plastic insulation of the esophagus wall suture line.
