摘要：
FIELD: medicine.SUBSTANCE: defected tracheal section is wrapped by a polypropylene biocompatible flexible separation film membrane. The membrane is placed to overlap its sides by 8-10 mm around the tracheal circumference and spaced at least 5 mm lengthwise over the defect. The membrane is covered by a lengthwise open tubular prosthesis with its open portion facing an oesophagus. The prosthesis is placed so that its one-piece non-traumatic borders of the open portion can be 8-10mm overlapped. The prosthesis length is equal to the membrane length. The wound is closed. The prosthesis is configured as a warp mesh of polypropylene monofilaments 0.13-0.15 mm in diameter, with stitch control along a needle wale of 14-16 loops/cm and a row of loops 4-5 loops/cm. The prosthesis also comprises rows of loops projecting through 8-10 mm on an outer surface transversely and accommodating a meander spiral. The spiral is made of the polypropylene monofilament 0.8-1.0 mm in diameter with the longitudinal direction of the turn translation at a pitch of 8-10 mm, at 12-15 mm from spiral crests from the borders of the open portion of the prosthesis. Three or four weeks later, a circular resection of the defected tracheal section is performed along the borders of the prosthesis. The defected section is removed together with the membrane. Interrupted sutures are applied to form single-layer anastomosis between the capsulated prosthesis and the intact proximal and distal ends of the trachea.EFFECT: reducing injuries and length of operation, number of postoperative complications and recurrences by using the prosthesis of optimum design, technique of the prosthesis laying on the defect, growing the prosthesis on the defect, growing the prosthesis with autotissue immediately within the tracheal defect with full-length continuous feeding of the formed capsule.4 dwg, 3 exИзобретение относится к медицине, а именно к реконструктивно-восстановительной хирургии, и может быть использовано при замеще
