The aim of the work – to analyze modern scientific and practical achievements in the effectiveness of implants in planned and emergency hernia surgery and to identify promising areas for further research. The literature review presents modern views on the assessment of biocompatibility, effectiveness and appropriateness of the use of implants in planned and urgent hernia surgery. The importance of determining the main factors of ventral hernia occurrence, assessing the prognostic components of the reparative process course in the field of hernioplasty and methods of correction has been substantiated. Physicochemical characteristics of implants, which both historically and on an up-to-date level are used according to planned or urgent conditions for performing surgical intervention in patients with ventral hernias, are given. The necessity of using an integrated approach to choosing a method for correction or reconstruction of the abdominal wall, taking into account the biological and dynamic conditions of its state, is shown. The need for a selective approach to the choice of therapeutic tactics in patients, especially if hernia repair is necessary in conditions of a clean-contaminated or infected surgical wound, is emphasized. Conclusions. In order to improve the consequences of hernioplasty, it is necessary to assess patient's reserves and risks more thoroughly and comprehensively, as well as to make absolute indications for the use of implants. An improvement in the results of urgent and planned repair of ventral hernias is to perform surgical interventions only in surgery departments constantly provided with modern world achievements.

The aim of the work. To analyze the world achievements in modern diagnostic and treatment tactics in patients with strangulated ventral hernias, as well as to outline promising and pragmatic directions for further research. The literature review presents current trends and views on the choice of individual components of the integrated diagnostic approach in patients with strangulated ventral hernias, and focuses on various principles of therapeutic tactics. The need to further improve the examination methods of abdominal organs, anterior abdominal wall, hernia contents (polypositional roentgenoscopy or roentgenography, ultrasound, CT, MRI) is emphasized and prospects of allohernioplasty and videolaparoscopic technologies with an integrated approach in choosing the method for correction or reconstruction of abdominal wall depending on the prognostic risk factors of postoperative complications are substantiated. Comparison of individual priorities of planned hernia surgery provided the opportunity to define the main directions in terms of urgent medical treatment features for patients with strangulated ventral hernias, taking into account a phasal nature of the pathological process and the availability and applicability of various synthetic implants. The literature analysis allowed for enough critical evaluation of the current state of tension-free allohernioplasty – the main fundamental principle of modern urgent surgery for ventral hernias and determining the main pragmatic directions of a selective approach in choosing the therapeutic tactics for patients with infected surgical wound. Conclusions. Urgent surgery of strangulated ventral hernias requires adequate and timely provision of individual and differentiated approaches in choosing the volume and method of surgery. Improvement of methods for predicting and preventing complications in patients with strangulated ventral hernias will expand the indications for the use of advanced types of tension-free hernioplasty.

BACKGROUND Increasingly intelligent and autonomous robots are destined to have a huge impact on our society. Their adoption, however, represents a major change to the healthcare sector’s traditional practices, which, in turn, poses certain challenges. To what extent is it possible to foresee a near-future scenario in which minor routine surgery is directed by robots? And what are the patients’ or general public’s perceptions of having surgical procedures performed on them by robots, be it totally or partially? A patient’s trust in robots and AI may facilitate the spread and use of such technologies. OBJECTIVE The goal of our study was to establish the factors that influence how people feel about having a medical operation performed on them by a robot. METHODS We used data from a 2017 Flash Eurobarometer (number 460) of European Commission with 27,901 citizens aged 15 years and over in the 28 countries of the European Union. The research designs and tests a technology acceptance model (TAM). Logistic regression (odds ratios, OR) to model the predictors of trust in robot-assisted surgery was calculated through motivational factors, robots using experience and sociodemographic independent variables. RESULTS The negative relationship between most of the predictors of ease of use, expected benefits and attitude towards robots, and confidence in robot-assisted surgery was contrasted. The only non-sociodemographic predictor variable that has a positive relationship with trust in robots participating in a surgical intervention is previous experience in the use of robots. In this context, we analyze the confidence predictors for three different levels of robot use experience (zero use, average use, and high use). The results obtained indicate that, as the experience of using robots increases, the predictive coefficients related to information, attitude and perception of robots become more negative. Research results also determined that variables of a sociodemographic nature played an important predictive role. It was confirmed that the effect of experience on trust in robots for surgical interventions was greater among men, people between 40 and 54 years old, and those with higher educational levels. CONCLUSIONS Despite the considerable benefits for the patient that the use of robots can bring in a surgical intervention, the results obtained show that trust in robots goes beyond rational decision-making. By contrasting the reasons that generate trust and mistrust in robots, especially by highlighting the experience of use as a key element, the research makes a new contribution to the state of the art and draws practical implications of the use of robots for health policy and practice.

Introduction: Cystine stone development is relatively uncommon among patients with urolithiasis, and most studies have reported only on small sample sizes and short follow-up periods. We evaluated clinical courses and treatment outcomes of patients with cystine stones with long-term follow-up at our center. Methods: We retrospectively analyzed 22 patients diagnosed with cystine stones between January 1989 and May 2019. Results: The median follow-up was 160 (range 6–340) months, and the median patient age at diagnosis was 46 (range 12–82) years. All patients underwent surgical interventions at the first visit (4 extracorporeal shockwave lithotripsy, 5 ureteroscopy, and 13 percutaneous nephrolithotripsy). The median number of stone events and surgical interventions per year was 0.45 (range 0–2.6) and 0.19 (range 0–1.3) after initial surgical intervention. The median time to stone events and surgical intervention was 2 years and 3.25 years, respectively. There was a significant difference in time to stone events and second surgical intervention when patients were divided at 50 years of age at diagnosis (p = 0.02, 0.04, respectively). Conclusions: Only age at a diagnosis under 50 was significantly associated with recurrent stone events and intervention. Adequate follow-up and treatment are needed to manage patients with cystine stones safely.

Abstract Purpose The objective of this systematic review is to compare the safety and efficacy of surgical fixation of rib fractures against non-surgical interventions for the treatment of flail chest in the adult population. Methods A search was performed on the 22nd of July 2020 to identify articles comparing surgical fixation versus clinical management for flail chest in adults, with a description of the outcome parameters (resource utility, mortality, adverse effects of the intervention and adverse progression in pulmonary status). Relevant randomised controlled trials were selected, their risk of bias assessed, and the data then extracted and analysed. Results 157 patients were included from four studies in the analyses, with 79 and 78 patients in the surgical and non-surgical groups, respectively. The pooled effects of all outcomes tended towards favouring surgical intervention. Surgical intervention was associated with lower rates of pneumonia (I2 = 46%, Tau2 = 0.16, p = 0.16), significantly lower rates of tracheostomy (I2 = 76%, Tau2 = 0.67, p = 0.02), and a significantly lower duration of mechanical ventilation (I2 = 88%, Tau2 = 33.7, p < 0.01) in comparison to the non-surgical management methods. Conclusion Our results suggest that surgical intervention reduces the need for tracheostomy, reduces the time spent in the intensive care unit following a traumatic flail chest injury and could reduce the risk of acquiring pneumonia after such an event. There is a need for further well-designed studies with sufficient sample sizes to confirm the results of this study and also detect other possible effects of surgical intervention in the treatment of traumatic flail chest in adults.

An algorithm for the diagnosis and treatment of infectious and inflammatory complications after endovideosurgical hernioplasty in patients with postoperative ventral hernias using traditional and minimally invasive methods of therapy was proposed. The study was based on the treatment results of 177 patients who underwent endovideosurgery for postoperative ventral hernias. Despite the perioperative antibiotic prophylaxis according to the accepted at the S.M. Kirov Military Medical Academy, according to the protocol scheme (first-generation cephalosporin at a dose of 1 g once parenterally 30 min before the operation, followed by repeated administration in case of operation duration of 3 h), course of the early postoperative period on days 35 in 8 (4,5%) patients after endovideosurgical hernioplasty was complicated by suppuration in the intervention area. When analyzing the causes of infectious and inflammatory complications, in both the main and control groups of observations, all suppuration in the area of surgical interventions was diagnosed in patients with metabolic syndrome (stages IIIII obesity and type 2 diabetes mellitus). The use of the negative pressure wound therapy resulted in wound cleansing for 4.1 2.5 days (p 0.05) and was comparable with the traditional method of treatment, but more active growth of granulation tissue prevailed in the wound, which contributed to its accelerated healing. The negative pressure wound therapy is effective in the systemic infectious and inflammatory process, especially after prosthetic hernioplasty of large W3-postoperative hernias. Drainage of abscesses under ultrasound navigation is possible with small (S 10 cm2) delimited purulent processes in the area of the polypropylene implant with the preservation of the latter.

Background: most of the gynaecological interventions are generally done under regional anaesthesia. Currently dexmedetomidine came out as a beneficial adjunct for regional analgesia as well as anaesthesia. It is a highly selective α-2 agonist. Aims & objectives: to compare the effects & behavior of dexmedetomidine with clonidine when both are used with bupivacaine for spinal analgesia. Material and Methods: 100 cases of ASA grade 1 & 2 who were undergoing elective gynaecological surgical intervention were studied. They were divided into two groups (50 each). Group I received combination of bupivacaine & clonidine while group II received combination of bupivacaine + dexmedetomidine. Results: Average duration of onset of sensory block was earlier in group II. Arrival of motor block in Group I was slightly on lower side than Group II. Ten cases in Group I and eighteen cases from group II had notable bradycardia and hypotension. Discussion: Our study concludes that dexmedetomidine when used in combination with bupivacaine is very effective in gynaecological surgical interventions that demand longer duration & have comparatively lesser side effects. Keywords: dexmedetomidine, clonidine, Bupivacaine, gynaecological procedures.

The clinical experience demonstrates the importance of 3D modeling when planning surgical intervention in patients with pulmonary tuberculosis. The 3D model was built up based computed tomography data using Avtoplan software with plug-ins for segmentation of the lung, pathological foci, vascular structures, and bronchial tree. The data obtained during 3D modeling allowed us to plan surgery and the data were fully confirmed during the operation. The 3D model with color mapping reveals syntopy, which is extremely difficult to determine using standard computed tomography and allows the wider use of minimally invasive endoscopic surgical interventions.

Objective: to determine the topical localization of the structural components of the anal sphincter and to formulate the basic postulates of the formation of safe anatomical access in pilonidal disease surgery in children. Materials and methods: the study was conducted on the corpses of 10 children who had no lifelong pathology of the sacrococcygeal region and pelvis aged 12 to 17 years, including 5 girls and 5 boys. Soft tissue columns 1 cm wide and up to 5 cm long were prepared at a distance of 1 cm from the anus by 12 h, 3 h, 6 h and 9 h according to the dial in the back position. After preparation and fixation of the drugs, their staining was performed and cross-sections of anal sphincters 5–7 μm thick were made. The analysis of the received morphometric data is carried out. The results of the study: it was found that the cross-sectional area of the bundle of muscle fibers of the external sphincter of the anus on average in adolescents ranged from 448±32 μm2 to 412±24 μm2. The diameter of its muscle fibers was 13.02±1.56 μm, and the bulk density of muscle fibers is 96.12±1.34%. Regarding the length of the internal anal sphincter, it was found that it is almost the same in different areas and is 1.3±0.03 at the level of 3 and 12 hours, 1.3±0.07 at the level of 6 hours and 1.2±0.03 at the level of 9 hours. In the study of the linear dimensions of the length of different portions of external anal sphincter in certain places of the biopsy revealed a predominance of parameters that were determined at 6 hours, respectively, 5.7±0.06 cm against 4.3±0.04 cm at 3 hours, and 12 hours, respectively 5.1±0.06 cm against 4.3±0.03 cm at 9 years. The thickness of the external sphincter of the anus at 6 hours, respectively 26.7±0.61 mm against 18.5±0.19 mm at 3 hours, (<0.01) and 12 hours, respectively 23.9±0.33 mm against 18.4±0.19 mm at 9 hours. Diameters of separate muscular fibers and bundles were explored. It is established that the average diameter of a muscle fiber makes 13.7±0.18 microns, and the average diameter of a muscular bundle is equal to 435.9±5.15 microns. Conclusions. 1. Existing anatomical descriptions of anal sphincters need in the modern world more thorough research to prevent their injury during surgery. 2. The external anal sphincter has the spatial form of the three-storeyed oval structure extended in the front-back direction with dominance of the caudal muscular portion. 3. When performing radical surgical interventions for pilonidal disease in children by cleft-lift method, it is necessary to complete the edge of surgical access at a distance of not less than 3 cm to the edge of the anal sphincter. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of participating institution. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the authors. Key words: pilonidal disease, children, morphometry, surgical intervention.
