METHOD FOR PREVENTION OF SEROMA FORMATION IN EARLY POSTOPERATIVE PERIOD Russian patent published in 2024 - IPC A61B17/03 A61B17/04 A61B17/00 

FIELD: chemistry.

SUBSTANCE: invention relates to surgery, namely to reconstructive and plastic surgery, oncology. Cranial portion of the skin flap and a caudal portion of the skin flap are fixed to the underlying tissues. Separate interrupted adaptive sutures are applied at distance of 1.5-2 cm from each other, uniformly distributing the tension of the skin flaps between the sutures. Needle is inserted through the nodal adaptation suture points marked on the skin of the mobilized area. At the same time, marking of points of application of interrupted adaptation sutures is carried out in such a way that a perpendicular first line in an anteroposterior direction and a second line are drawn through a surgeon-defined wound centre, which is carried out in the caudal direction perpendicular to the first line from the centre of the wound to its most distant section. Then the first line is divided into four equal parts, and the second line is divided into three equal parts. Then, through points dividing the first and second lines into equal parts, perpendicular lines are drawn, which form points of nodal adaptation sutures at their intersections. Then the above lines and their points of intersection are projected on the opposite edge of the wound, thus marking the points of application of interrupted adaptation sutures on the opposite edge of the wound. After pricking, the needle passes through the thickness of the skin, subcutaneous fat, captures the muscle lining the bottom of the wound, and is output in the opposite direction, passing through the same layers, pricking out on the skin at the pricking point, wherein the knots are tightened from the outside; sutures are applied in accordance with the markings, starting from above from the lateral to the medial edge of the cranial section of the skin flap. Then the caudal section of the skin flap is stitched in the same way, starting from its lower edge; after suturing the cranial and caudal skin flaps, the incision is closed intradermally over the entire area of the dead space.

EFFECT: method enables to provide a stable fixation of the free-lying flap to the underlying tissues of the thoracic fascia, in order to quickly heal wound surfaces and persistent obliteration of the "dead space", as well as to provide a uniform distribution of tension of the skin flap and underlying tissues between the sutures, due to which the wound to be closed remains without tension, which, in turn, reduces the risk of ischemic and infectious complications, thereby significantly reducing the rehabilitation period and improving the quality of life of the patient in the postoperative period.
