The article provides a literature review of the methods for the prevention of local infectious complications preoperative, intraoperative and postoperative. The analysis of the literature is devoted to the methods of prevention of postoperative purulent inflammatory wound complications. The review of scientific medical literature is based on the analysis of this problem. The article presents risk factors that contribute to the development of postoperative wound complications. Classification of surgical wounds was adopted to determine the risk of developing a surgical site infection (SSI), which distinguishes 4 classes: clean, conditionally clean, contaminated and dirty. The presented classification is based on the postoperative assessment of the wound bacterial contamination rate. The ClavienDindo classification of postoperative complications is the most relevant. This classification presents the tactics of the surgeon, depending on the class. The results of various studies indicate that antibiotic prophylaxis in the preoperative period reduces the development of local complications. The description of prevention methods focuses on intraoperative methods (devices for bringing together the edges of the wound, devices for treating wounds, surgical needles, suture material) and various types of antiseptics, which can reduce tissue damage during surgical interventions, reduce microbial contamination and the number of wound postoperative complications. Intraoperative instrumental methods allow less pronounced trauma to the wound during its processing and suturing. The postoperative method for diagnosing wound complications is an ultrasound method, which determines various formations in a postoperative wound.
Aim. To improve the results of surgical treatment of patients with large soft tissue lipomas by developing and implementing of adaptation-distraction device for rapprochement of wound edges.Methods. During the period from 2012 to June, 2016, 61 patients with various localization of large soft tissue lipomas were hospitalized to the department of surgery of Kazan Hospital for war veterans. The patients were divided into 2 groups: control group included 35 (57.4%) patients who had the traditional mass excision with wound sealing, and the study group included 26 (42.6%) patients, on whom instrumental method was applied with the use of adaptation-distraction device for rapprochement of wound edges in order to reduce tissue trauma during removal of the lump and suturing tissues.Results. Clinical use of adaptation-distraction device for removing various tumors of the skin and subcutaneous tissue has demonstrated its advantage over traditional methods. Optimal conditions for radical removal of the tumor with maximum compliance with the rules of ablastics and antiblastics with minimal blood loss (20-45 ml) are created. In control group postoperative wound complications included 2 (5.7%) hematomas and 1 (2.8%) seroma. In the study group 1 (3.8%) patient had hematoma.Conclusion. Use of adaptation-distraction device provides preliminary circular local tissue compression directly near the tumor and in its base, which leads to local preventive hemostasis in surgical wound area without shutting down the blood flow in surrounding tissues; the device allows to make the imposition of primary seams not interrupting the surgery and to avoid eruption.
Aim. To study the effect of pyrimidine medication hydroxyethyldimethyldihydropyrimidine on the systemic inflammation after prosthetic repair of the anterior abdominal wall hernia. Methods. We prospectively analyzed two groups of patients aged between 18 and 80 years, who underwent prosthetic repair of the aponeurosis defect in the anterior abdominal wall hernia with a standard polypropylene mesh implant. The main group (n=16) was given 0.5 g hydroxyethyldimethyldihydropyrimidine per os 3 times a day before meals for 57 days from the first day after the operation. In the control group (n=16), patients received basic therapy without hydroxyethyldimethyldihydropyrimidine. Results. The postoperative period in patients after elective prosthetic hernioplasty of anterior abdominal wall was associated with an imbalance of the immune system with a tendency to lymphocytopenia (count in blood changed by 27.0%; p=0.20, Wilcoxon criterion) without significant leukocytopenia (count in blood changed by 4.9%; p=1.00, Wilcoxon criterion) and an 82.8% increase in C-reactive protein content (p=0.2, Wilcoxon criterion) compared to baseline values before the surgery. The proposed pharmacological support of prosthetic hernioplasty of the anterior abdominal wall with hydroxyethyldimethyldihydropyrimidine allowed to correct the postoperative lymphocytopenia (p=0.04, U-criterion) and reduce the concentration of C-reactive protein by 223.6% (p=0.03, U-criterion) compared with the control, which was also associated with a decrease in the number of local complications of prosthetic hernioplasty. Conclusion. The use of hydroxyethyldimethyldihydropyrimidine in patients after prosthetic hernioplasty is associated with a significant decrease in the C-reactive protein level, prevention of postoperative lymphocytopenia and a decrease in the number of local wound complications; C-reactive protein level can serve as one of the early and significant indicators of postoperative complications in this category of patients.
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.
