Aim. To improve the results of treatment of patients with breast cancer after radical mastectomy through the development and application of a device for wound closure after radical mastectomy, providing favorable conditions for wound healing. Methods. The proposed device for wound closure after radical mastectomy was used in 42 patients after the mandatory informed consent. A patent for the invention was obtained for the developed device. The study group included patients with indications for performing Madden mastectomy (Halsted, Patey) for breast cancer in the range of stages T1-4N0-1M0. The age of the patients was 57.5±10.4 (m±δ) years. In group 1 (n=21), wound closure after radical mastectomy was performed using the developed device, in group 2 (n=21) - without it. Results. In the process of working with the developed device, the following positive features were observed. The magnitude of the buckling in the plane of the jaws follows the contour of the thorax in the region of operation of the patient preventing the appearance of the plots of overpressure by the device to the adjacent tissue and ensuring uniformity of traction paravulnar tissues. The complete absence of tissue tension in the area of the suture is the result of the suturing of surgical wounds only after the complete wound edges attachment by means of the device. The above-mentioned factors lead to the formation of point scars in the joints, the absence of extended forms of postoperative scars. Conclusion. The developed device for wound closure after radical mastectomy performed for breast cancer allows shortening the hospital stay after surgery by 36% (p=0.01) and the deadline for removal of drainage by 31% (p=0.01), reducing the incidence of local necrosis of the flap (p=0.44) compared to traditional suturing of the wounds.
