Laparoscopic Access in Radical Surgical Treatment of Complicated Gastric Cancer: a Single-Center Experience

Over the past decades, there has been an active introduction of minimally invasive surgical technologies in the treatment of various diseases, including gastric cancer. In Asian countries and Europe, laparoscopic gastrectomy is an alternative to open gastrectomy for early gastric cancer, with a tendency to displace the latter. In the Russian Federation, laparoscopic gastrectomy is performed in a few specialized centers. From 2013 to 2022, the surgeons of our Center treated 141 patients diagnosed with gastric cancer at different stages (64 men, 39 women, mean age of 60.5±10 years). Of these, 52 patients (50.5%) underwent open surgeries (group I), 51 (49.5%) — laparoscopic surgeries (group II). The study included patients diagnosed with gastric cancer complicated by bleeding or gastric outlet/cardioesophageal junction obstruction, over 18 years of age, who signed consent for the processing of personal data and inclusion of their clinical data in the research and underwent surgical treatment. We analyzed such parameters as the duration of surgical intervention and the duration of hospital stay, the rates of hospital/relapse-free 2-year survival, and uncomplicated postoperative period. Laparoscopic-assisted surgeries lasted longer; however, due to more precise technique and better visualization of anatomical structures, there was a smaller volume of intraoperative blood loss. During laparoscopic-assisted radical gastrectomy, it is possible to perform more precise lymph node dissection, increase the number of harvested lymph nodes and, thus, increase the probability of detecting lymph nodes with metastases; which, in turn, has a direct impact on increasing the 2-year relapse-free and 2-year overall survival of patients. There was no significant difference in the incidence or severity of postoperative complications and mortality. These data are an important indicator of the effectiveness of the minimally invasive surgical method of treatment, which indicates greater safety of the laparoscopic method compared to intervention from laparotomy access.

Искусственный интеллект для планирования тактики ведения пациентов после перкутанной нефролитотрипсии.

Introduction. Urolithiasis remains one of the most common urological pathologies that deserves due attention in the healthcare system. A current direction in optimizing percutaneous nephrolithotripsy (PСNL) is a personalized prognosis for patient management based on artificial intelligence (AI) decisionmaking algorithms. In our work, we applied an algorithm to create the most optimal tactics for patient management after PCNL. Purpose. Optimize the management of patients after PCNL based on AI. Materials and methods. The total number of patients treated at N. Lopatkin Scientific Research Institute of Urology and Interventional Radiology andthose who took part in the study amounted to 1000 people. The number of men was 419 (41.9%), women 581 (58.1%). The age of patients included in the studies ranged from 18 to 88 years (52.3±13.47). The division into Training and Holdout partitions varied depending on the target variable to obtain the most accurate result. The maximum difference in the samples was 600n and 400n (60% and 40%), the minimum 800n and 200n (80% and 20%). Data processing was carried out using IBM SPSS Statistics and Modeler programs using the neural network modeling method. Results. The accuracy of prediction for the choice of nephroscope size was 82.2%, requirement for intraoperative stent placement 93.9%, requirement for ureteroscopy or contact ureterolithotripsy 98.5%. The accuracy of the forecast for the number of puncture accesses was 92.6%, for access through the upper group 95%, for access through the middle group 91.2%, for access through the lower group 91.2%. The algorithm allows us to predict the presence of residual stones with an accuracy of 84.1%, the duration of surgical intervention is 87.3% Conclusion. Further development of AI technology will not only provide a «second opinion» and reduce the time for processing large volumes of information, but will also standardize the approach to the treatment of complex clinical cases and help optimize the work of the urology department.

Robotic versus Mini-Laparoscopic Colposacropexy to Treat Pelvic Organ Prolapse: A Retrospective Observational Cohort Study and a Medicolegal Perspective.

Background: POP (pelvic organ prolapse) involves the descent of one or more pelvic organs downwards with or without protrusion from the vaginal opening, caused by the relaxation and weakening of ligaments, connective tissue, and pelvic muscles. Such an outcome negatively impacts the quality of life. The gold standard procedure for repairing apical compartment prolapse is colposacropexy (CS) to secure the anterior and posterior walls of the vagina to the anterior longitudinal sacral ligament, located anteriorly to the sacral promontory, using a mesh. Several surgical approaches are feasible. Laparotomic or minimally invasive methods, including laparoscopic or robotic ones, can restore the horizontal axis of the vagina and typically involve concomitant hysterectomy. Methods: This study is based on 80 patients who underwent CS at Palermo's Ospedali Riuniti Villa Sofia-Cervello from 2019 to 2023. Women aged 35-85 at the time of surgery were divided into two groups: 40 patients underwent mini-laparoscopic surgery, and 40 patients underwent robotic surgery. The following parameters were accounted for: demographic data (initials of name and surname, age), preoperative clinical diagnosis, date of surgery, surgical procedure performed, estimated intraoperative blood loss, duration of surgical intervention, length of hospital stay, postoperative pain assessed at 24 h using the VAS scale, and any complications occurring in the postoperative period. Mini-laparoscopic CS (Minilap) and robotic CS (Rob) were then compared in terms of outcomes. Results: In the Minilap group, 11 patients out of 40 had a preoperative diagnosis of vaginal vault prolapse. The average age in this group was 61.6. Five of these patients had isolated cystocele, while the rest presented vaginal stump prolapse linked to cystocele, rectocele, or both. The remaining 29 patients in the Minilap group had a preoperative diagnosis of uterovaginal prolapse, also associated with cystocele, rectocele, or both, or isolated in nine cases. In the Rob group (average age: 60.1), 13 patients were diagnosed with vaginal prolapse (isolated or associated with cystocele), while the remaining 27 had a diagnosis of uterovaginal prolapse. In the Minilap group, the average procedure duration was 123.3 min, shorter than the Rob group (160.1 min). Conclusions: The data collected throughout this prospective study point to the mini-laparoscopic approach as being preferable over the robotic one in terms of surgical procedure length, intraoperative blood loss, postoperative pain, and aesthetic outcome. Hospital stay duration and post operative complication rates were similar for both groups. The innovative and ever-progressing nature of such procedures calls for novel standards prioritizing patient care as well as medicolegal viability.

Relevance. Despite the rapid development and predominance of endovideosurgical techniques in the treatment of pathologies of organs and structures of the retroperitoneal space, the implementation of transperitoneal or retroperitoneal approaches for open surgical interventions remains a routine activity. Surgical treatment of various pathologies of retroperitoneal localization leads to the development of nonspecific life-threatening complications in 23.8% - 30% of clinical observations, and associated mortality - 7.2% - 11% of cases. Previously, our works presented the results of comparing the number of this type of complications when using laparotomy or retroperitoneal access, depending on the constitutional parameters of the patient. An assessment was made of the significance of the influence of constitutional parameters on the development of nonspecific life-threatening complications, on the basis of which an algorithm for choosing the optimal surgical access to the structures of the retroperitoneal space was developed [patent application No. 2024113445 dated May 17, 2024]. Purpose of the study. To evaluate the effectiveness of using an algorithm for selecting the optimal surgical approach in the surgical treatment of pathologies of organs and structures of retroperitoneal localization. Materials and methods. Comparative analysis of the results of surgical treatment of patients with various surgical pathologies of the retroperitoneal space. Group I (n = 167), where the choice of surgical approach was determined using the “optimal surgical approach selection algorithm.” Group II (n = 284), in which the choice of access to the structures of the retroperitoneal space was not unified and was chosen without taking into account the constitutional parameters of the patient. In the perioperative period, the duration of surgical intervention, the volume of intraoperative blood loss, the number of days of stay in the intensive care unit, the time of postoperative respiratory support, the duration of postoperative intestinal paresis and the number of postoperative bed days were assessed. Criteria assessed in the postoperative period: development of myocardial infarction, acute cardiovascular failure, ARDS with the development of respiratory failure, acute kidney injury; cases of development of ischemic colitis and small intestinal obstruction, requiring repeated interventions, as well as the phenomenon of multiple organ failure. Wound complications included failure of retroperitoneal and laparotomy wounds, including eventration. To calculate quantitative characteristics, the median (Me) and percentiles (Q0.25 - Q0.75) were determined. Calculation of statistical significance between groups was performed using the Mann-Whitney U test**, for comparison of qualitative indicators - the Chi-square test* in IBM SPSS Statistics 25 software. Results. In group I, compared with group II, there was a shorter surgical intervention time [140.8 vs 179.5] min, p = 0.031**, a smaller volume of intraoperative blood loss [280.4 vs 413.3] ml, p = 0.024* *; postoperative respiratory support [4.5 vs 8.5] hours, p = 0.041**; length of stay in the intensive care unit [1.8 vs 3.4] days, p = 0.021**; postoperative intestinal paresis [1.2 vs 4.8] days p = 0.024**; and duration of total postoperative hospital stay [9.1 vs 16.4] days p = 0.003**. The number of postoperative nonspecific life-threatening and wound complications in group I was 24 (14.4%), and in group II - 64 (22.5%) cases (p = 0.023*). The number of complications-related deaths in group I was 9 (5.4%); in group II - 32 (11.26%) cases (p = 0.037*). Conclusion. The use of an algorithm for selecting the optimal surgical approach for surgical treatment of pathologies of organs and structures of the retroperitoneal localization of the access leads to a reduction in the number of nonspecific life-threatening complications to 14.4%, and associated deaths to 5.4%.

Early silent coronary bypass graft occlusion following coronary bypass surgery, implication of routine coronary computed tomography angiography

ObjectiveTo evaluate incidence and predictors of early silent bypass occlusion following coronary bypass surgery using cardiac computed tomography angiography.MethodsA total of 439 consecutive patients with mean age of 66 ± 10 years comprising 17% (n = 75) females underwent isolated coronary bypass surgery followed by CT scan before discharge. Graft patency was evaluated in 1,319 anastomoses where 44% (n = 580) arterial and 56% (n = 739) vein graft anastomosis were performed. Cardiovascular risk factors, demographics, and intraoperative variables were analyzed. We conducted univariable and multivariable logistic regression analyses to analyze variables potentially associated with graft occlusion following CABG. Variables included gender, surgery duration, graft flow, pulsatility index, vein vs. artery graft, and recent MI.ResultsOverall incidence of graft occlusion was 2.4% (31/1,319), and it was diagnosed in 6.6% (29/439) of patients. The difference in occlusion between arterial (2.1%) and vein (2.6%) grafts was not significant, p = 0.68. The duration of intervention p = 0.034, cross clamp time p = 0.024 as well the number of distal anastomosis p = 0.034 were significantly higher in occlusion group. The univariate and multivariate logistic regression indicated duration of surgery being predictive for bypass graft occlusion with OR = 1.18; 95% CI: 1.01–1.38; p = 0.035.ConclusionsEarly graft occlusion was associated with surgical factors. The number of distant anastamoses, along duration of surgical intervention were, significantly influenced the risk of EGO. Prolonged procedural time reflecting complex coronary pathology and time-consuming revascularization procedure was as well associated to the elevated risk of occlusion.

Methods of preventing surgical site infections

Healthcare-associated infections are the most common and relevant to all healthcare facilities of all types. Surgical site infections are the most frequently reported type of healthcare-associated infections. Surgical site infections are also one of the main causes of prolonged hospital stays, prolonged antibiotic therapy, unplanned re-hospitalizations, worsened long-term patient outcomes and the prescription of additional surgical interventions. At present, it is prevention that has been identified as the single most important strategy to combat surgical site infection. The proposed three-stage model combines perioperative interventions as well as interdisciplinary collaboration to continuously improve the quality of care. This approach includes preoperative, intraoperative, and postoperative prevention methods. Current preoperative strategies for the prevention of surgical site infections can significantly reduce the risk of developing this nosology; one important aspect of preoperative prophylaxis includes the identification, elimination, and/or correction of modifiable as well as non-modifiable risk factors. In addition, it is possible to identify intraoperative risk factors, of which the duration of surgical intervention is fundamentally important. Postoperative risk factors include hyperglycemia and diabetes mellitus, postoperative wound care and blood transfusion. Many effective ways of preventing surgical site infections have been developed, which include separate methods of preoperative, intraoperative and postoperative prophylaxis, however, only through the implementation of a comprehensive model that combines all perioperative measures, health care institutions will be able to effectively reduce the incidence of healthcare-associated infections and improve patient outcomes. Despite the fact that currently there is an active development of new methods of surgical site infections prophylaxis, the direct implementation of these technologies in the practical activity of specialists is of primary importance.

Introduction. In recent years, there has been more and more research on the creation of artificial intelligence (AI) to help diagnose and treat patients in various fields of medicine. The use of algorithms allows us to reduce the time for processing large volumes of information and give a «second opinion» to a specialist in complex and non-standard clinical cases. In order to increase the effectiveness of percutaneous nephrolithotripsy, we have created an AI algorithm to personalize approach in the surgical treatment of nephrolithiasis. Purpose. To develop a universal tool for predicting the most optimal tactics of percutaneous nephrolithotripsy depending on the clinical case. Materials and methods. The total number of patients treated at N. Lopatkin Scientific Research Institute of Urology and Interventional Radiology and those who took part in the study amounted to 1000 people. The number of men was 419 (41.9%), women 581 (58.1%). The age of patients included in the studies ranged from 18 to 88 years (52.3±13.47). The division into Training and Holdout partitions varied depending on the target variable to obtain the most accurate result. The maximum difference in the samples was 600n and 400n (60% and 40%), the minimum 800n and 200n (80% and 20%). Data processing was carried out using IBM SPSS Statistics and Modeler programs using the neural network modeling method. Results. The accuracy of prediction for the choice of nephroscope size was 82.2%, requirement for intraoperative stent placement 93.9%, requirement for ureteroscopy or contact ureterolithotripsy 98.5%. The accuracy of the forecast for the number of puncture accesses was 92.6%, for access through the upper group 95%, for access through the middle group 91.2%, for access through the lower group 91.2%. The algorithm allows us to predict the presence of residual stones with an accuracy of 84.1%, the duration of surgical intervention is 87.3%.The number of test observations was 30. The algorithm demonstrated high accuracy of prediction (from 73.8% to 94.5%) of surgical tactics in complex clinical cases. Conclusion. The results of using the algorithm for personalized prognosis in the surgical treatment of nephrolithiasis showed high accuracy and efficiency. Further development of technology to create algorithms for each nosology and surgical interventions will reduce the time of data analysis by the attending physician, provide a «second opinion» to young specialists and standardize the approach to treatment in rare and complex clinical cases.

Assessment of the Diagnosis-To-Needle Times for Patients Admitted to the Emergency Department with Acute ST-Segment Elevation Myocardial Infarction

Abstract Background Coronary artery disease is one of the most common causes of death in the world. The outcome of patients with ST-elevation myocardial infarction is influenced by many factors, and the time elapsed from symptom onset to diagnosis and reperfusion have a critical role in this regard. Aim The aim of this study was to investigate the differences in the diagnosis-to-needle times of patients with STEMI presenting to the hospital during and outside of working hours, and the effect of this relationship on in-hospital clinical events. Methods This retrospective study analyzed the data of 50 patients admitted for emergency primary percutaneous coronary intervention. We assessed pain onset-to-diagnosis times and diagnosis-to-needle times, and evaluated their relationship with troponin values at admission and after 48 h. Results The mean age of the patients was 55.64 ± 13.72 years. In total, 60% of the patients presented outside of working hours. Mean patient delay time from the onset of chest pain to seeking medical help was 2.64 ± 2.47 h. Mean troponin values were 4.39 ± 5.26 ng/ml at admission and 36.50 ± 12.95 ng/ml after 48 h. Mean post-angiography ejection fraction values were 47.36 ± 6.53%. We found a statistically significant difference in the pain onset-to-diagnosis and diagnosis-to-needle times of patients who presented to the hospital during and outside of working hours. We found a positive correlation between diagnosis-to-needle times and the troponin values of patients, and a statistically significant difference between pain onset-to-diagnosis times of patients who presented during and outside of working hours (p < 0.05). Although the relationship between the diagnosis-to-needle time and troponin elevation after 48 h was strong (97%), the relationship between pain onset-to-diagnosis time and troponin elevation after 48 h was weak (8%), suggesting that the duration of surgical intervention is much more important than the time until the first medical contact. Conclusions In this study, there was a statistically significant difference in the pain onset-to-diagnosis and diagnosis-to-needle times of patients who presented to the hospital during and outside of working hours.

Differential diagnosis and treatment of nosocomial spinal infections in patients after open microdiscectomy (brief literature review)

Surgical site infections (SSI) occur in 0.7‒16.1 % of cases and are one of the most frequent nosocomial complications in spinal neurosurgery. The frequency of SSI after open microdiscectomies varies from 1.9 % to 5.5 % depending on several factors and requires clarification. The causative agents of spinal SSI are most often Staphylococcus aureus, S. epidermidis, methicillin-resistant S. aureus, less frequently anaerobic strains, and Mycobacterium tuberculosis.Symptoms of deep SSI caused by the most common Gram-positive and Gram-negative microflora are usually nonspecific and include fever, back pain, and limited movement. Anaerobic spondylodiscitis is characterized by long-lasting back pain, mainly without an increase in temperature, and a high frequency of epidural abscess formation. The most significant factors in the occurrence of SSI are surgical access, type and duration of surgical intervention, the number of levels operated on at once, the duration of hospitalization, the presence of diabetes, and the patient’s high body mass index. However, the importance of each of these and other factors in the development of SSI after surgical interventions for clinically manifest discogenic pathology continues to be studied. In several studies, open microdiscectomies were statistically significantly associated with a higher frequency of SSI formation. Posterior spondylodesis and implants in the spine increase the risk of SSI development. Prevention of SSI should include preoperative, intraoperative, and postoperative stages, compliance with which can contribute to reducing the risk of SSI. Treatment of purulent spondylodiscitis involves antibiotic therapy and long-term dynamic observation. Indications for surgical intervention are the effectiveness of antibiotic therapy, deterioration of neurological symptoms, and violation of the integrity of the vertebrae with the formation of instability. The issue of choosing the optimal access and volume of surgical intervention for postoperative spondylodiscitis is analyzed in many studies and, first of all, is determined by: localization, the nature of structural changes, the presence of accompanying abscesses, the degree of neurological deficit, the presence or absence of vertebral compression fractures and signs of spondylolisthesis.Postoperative SSI worsens patients’ quality of life and disease prognosis in patients with discogenic pathology. A clear understanding of the individual risk factors of SSI, timely diagnosis, and differentiated treatment can prevent the formation of these dangerous complications and minimize their manifestations.

THE ROLE OF 3D MODELING IN INCREASING THE EFFICIENCY OF SURGICAL TREATMENT AND RESTORING THE QUALITY OF LIFE OF PATIENTS WITH MALIGNANT BONE TUMORS

Summary. Aim: to determine and study the clinical value of 3D modeling in increasing the effectiveness of treatment of patients with malignant bone neoplasms. Object and methods: endoprosthesis of hip and knee joints was performed in 69 patients after resection of a bone segment with a tumor, the boundaries of which were determined using a 3D model. Tumor models were made from optically opaque polylactide polyester, peritumoral tissues from optically transparent polylactide. Results: planning and training on 3D models significantly reduced intraoperative blood loss, duration of surgical intervention, and recovery time of limb functions. The use of training 3D models before surgical intervention with possible subsequent prosthetics with special oncological endoprostheses ensures satisfactory functional results and creates conditions for restoring the quality of life of patients. Conclusions: the proposed technique provides valuable experience in the way of implementing the principles of personalized treatment into surgical practice and creates conditions for optimizing the quality of life of patients.

Clinical characteristics, diagnostic methods and results of surgically treated histologically benign cardiac myxomas.

Myxomas are primary cardiac tumours that may be detected incidentally due to embolic events, intracardiac obstructive features or non-specific structural symptoms. The aim of this study was to share our experience of clinical features, diagnostic methods, surgical procedures and postoperative follow up of surgically treated cardiac myxomas. Data of 34 patients who underwent surgery for a cardiac myxoma between January 2006 and June 2022 were retrospectively analysed. Group 1 (n = 19) consisted of patients who were symptomatic and group 2 ( n = 15) patients were asymptomatic. The medical records of the patients, their clinical status, diagnostic methods, operation information and postoperative course data were collected and recorded. A total of 34 patients (16 female; mean age 54.5 ± 8.8 years) underwent cardiac myxoma resection with cardiopulmonary bypass. Fifteen (44.1%) patients were diagnosed incidentally with asymptomatic myxoma. An additional cardiac surgical procedure was performed in six patients (17.7%). The 34 cardiac myxomas that were surgically resected were localised in the left atrium in 25 patients (73.5%) and in the right atrium in nine patients (26.5%). Patients' most common symptoms were dyspnoea (42.1%), palpitations (21.1%), ischaemic stroke (15.8%) and syncope (10.5%). There was no incident of 30-day mortality and no recurrence was observed in any patient during the follow-up period. The duration of surgical intervention in symptomatic patients was significantly shorter than in asymptomatic patients (p = 0.0001), but there was no statistical difference in terms of characteristics. Myxomas are benign tumours, but they are serious pathologies that require early treatment because of signs of obstruction, embolic complications and confusion, with left atrial thrombus in the differential diagnosis.

A comprehensive approach to the prevention and treatment of massive obstetric hemorrhage

In the case of progression of obstetric haemorrhage (OH) and non-effective preventive and therapeutic measures during childbirth and after delivery, the volume of blood loss can increase and exceed > 1.5% of body weight (25–30% of circulating blood volume – CBV). In such cases that we are talking about massive obstetric haemorrhage (MOH), which leads to an increase in the frequency of maternal morbidity and mortality.The objective: determine the effectiveness of various approaches to the restoration of blood loss in the cases of MOH development, which occurred to various etiological factors, with the introduction of the modern concept of damage control resuscitation (DCR) and innovative methods of surgical hemostasis.Materials and methods. During 2015–2023 years at five clinical bases of the Department of Obstetrics and Gynecology N1 of Shupyk National Healthcare University of Ukraine we analyzed 165 cases of MOH. In all MOH cases, an integrated approach was used to stop haemorrhage using both drug therapy and modern methods of surgical hemostasis in accordance with the regulatory documents of the Ukrainian Ministry of Healthcare.In main group of 59 women in labor with the MOH (2020–2023 years) an integrated approach to stop haemorrhage and restore the blood loss according to DCR concept with the priority of high-quality and rapid CBV restoration with blood products and minimization of infusion therapy was used. The comparison group consisted of 106 women in labor with MOH (2015–2019 years) and similar methods of haemorrhage termination to restore blood loss in accordance with the order N 205 of the Ukrainian Ministry of Healthcare «Obstetric haemorrhage» with the priority of rapid restoration of blood loss by crystalloids (during 2015–2019 years).Results. The mean blood loss, time till haemorrhage is stopped, and the duration of surgery in the main group were significantly lower than in the comparison group (p<0.05). In the postpartum period the number of cases with severe anemia was significantly more often in the comparison group – 47.2% versus 11.9% in the main group (OR 6.6 CI 2.7–15.9; p<0.01), as well as the frequency of hysterectomy – 50.9% versus 28.8% (OR 2.6 CI 1.3–5.1; p<0.01).An early onset and a significantly higher rate of transfusions of fresh frozen plasma and erythrocyte mass were found in the main group – respectively 88.1% versus 38.7% in the comparison group (OR 11.7, CI: 4.8–28.4; p<0.001). This resulted in a significantly lower volume of blood loss, duration of surgical intervention, and average time for haemorrhage stop in the main group compared to the comparison group (p<0.05).Conclusions. The use of modern uterotonic agents (carbetocin), tranexamic acid preparations, innovative surgical technologies and early initiation of transfusion therapy with blood preparations with minimization of crystalloid infusion and according to the DCR concept for the development of MOH allows to reduce the volume of blood loss, the frequency of severe postpartum complications, and to prevent maternal morbidity and death.

USE OF MEDICAL ADHESIVES FOR CLOSING SCHNEIDER MEMBRANE PERFORATION DURING OPEN SINUS LIFTING (LITERATURE REVIEW)

The open sinus lifting procedure during dental implantation can cause perforation of Schneiderian membrane. Nowadays there are many methods of closing perforation of the sinus membrane. However, frequent intraoperative and postoperative complications require to search new methods and materials for increasing the productivity of the operation and reducing the duration of surgical treatment of patients.
 The purpose of the research: to analyze of modern Ukrainian and foreign scientific literature about the use of medical adhesives for closing the perforation of Schneiderian membrane during open sinus lifting surgery and to assess their effectiveness.
 Scientific information on the research topic was obtained from the resources of search engines: the electronic library of abstracts and dissertations of Vernadsky V.I. National Library of Ukraine, PubMed, Medline, MedNet, Embase, BMJ Group, Free Medical Journals, Free Medical Book, Scirus.
 Based on the analysis of the literature data, it has been found that medical bioadhesives are the newest materials used in dental practice, have the advantages of fast and painless application, resistance to infection, hemostatic properties, lack of toxicity, good sealing of wound surfaces, high tissue strength and are comfortable for patients. The use of compounds with new positive qualities in maxillofacial surgery, along with the introduction of modern technologies, equipment and tools, will increase the productivity of open sinus lifting surgery during dental implantation, reduce the number of intraoperative and postoperative complications, the duration of surgical interventions, and will allow performing operations with the least risk to the patient at a high professional level.

Effect of Adding Dexamethasone to Bupivacaine in Ultrasound Guided Adductor Canal Block for Post-operative Analgesia Following Knee Arthroscopy

Abstract Background Arthroscopic knee surgery refers to a large variety of surgical interventions in the knee, and numerous analgesic regimens have been investigated in order to find the best combination of analgesics for these procedures. The post-operative pain response depends on the type and duration of surgical intervention, and it can be challenging to predict which analgesic regimen will be the most appropriate for each patient until after surgery. Aim of the Work Assessing the effect of adding dexamethasone perineurally to bupivacaine in adductor canal block for post operative analgesia following knee arthroscopy under spinal anaesthesia regarding; duration of postoperative analgesia as a primary objective and one-day postoperative analgesic and opioid consumption as a secondary objective. Patients and Methods The type of study was a randomized prospective double blinded controlled clinical trial at Ain Shams University Hospitals, Cairo, Egypt. Study Period: Six months, Adult patients undergoing Knee Arthroscopy under Spinal Anaesthesia will be randomly assigned into one of the following groups using computer generated codes and opaque sealed envelopes: Group A (study group): The patients received ACB with 20 ml plain bupivacaine (0.25%) + 8 mg dexamethasone (2 ml), Group B (control group): The patients received ACB with 20 ml plain bupivacaine (0.25%) + 2 ml of Normal saline. Results There was a highly statistically significant difference between groups according to analgesic duration (time of first call for analgesics) (min) with p-value (p < 0.001). The highest value was found in group A(study) and group B(control) (241.02±36.15 and 188.49±28.27) respectively, this indicates that that the needs of analgesic in the group B were earlier compared to group A. There was a highly statistically significant difference between groups according to cumulative morphine consumption “mg” with p-value (p < 0.001). The highest value was found in Group B and Group A 4 (3-4) and 2 (1-2) respectively, this indicates much higher needs of analgesic in the Group B than group A. Conclusion We concluded that ACB is a good postoperative analgesic choice for arthroscopic knee surgery under spinal anaesthesia. However, adding (8 mg)dexamethasone to(0.25%) bupivacaine in ACB provided better prolonged postoperative analgesia and less analgesic consumption than bupivacaine alone.

Stapes surgery for otosclerosis: Comparison of two techniques

Abstract BACKGROUND. Otosclerosis is a primary disease of the human otic capsule and stapes stage, being a frequent cause of conductive hearing loss in our country. The surgical treatment of choice is stapes surgery and prosthesis placement, performed in a conventional way, with a surgical microscope, for 30 years in our hospital. Recently, the option of performing stapes surgery endoscopically was introduced in our centre. OBJECTIVE. To evaluate the results in stapes surgery for otosclerosis between the conventional microscopic versus endoscopic procedure. MATERIAL AND METHODS. An observational, analytical and retrospective study on patients undergoing stapes surgery with microscopic and endoscopic technique was conducted. Data such as age, sex, state of origin, affected ear, as well as the technique used, duration of surgical intervention, hearing gain and postsurgical complications were taken. Data were taken from the records of patients admitted to the hospital. Descriptive statistics, Mann-Whitney U and Pearson’s Ji2, were used, considering a value of p≤ 0.05 as significant. RESULTS. No significant differences were found in surgical time or postoperative hearing between the two surgical techniques. The female sex was the most intervened. There was no significant difference between the post-surgical complications of both groups. CONCLUSION. Both procedures appear to be effective, with similar risks and postoperative results for the surgical treatment of otosclerosis.

Association between insulin resistance indices and perioperative functional status and immediate prognosis in patients with carbohydrate metabolism disorders undergoing coronary artery bypass grafting

Highlights. Patients with coronary artery disease undergoing coronary artery bypass grafting have a high prevalence of type 2 diabetes mellitus and prediabetes. The frequency of postoperative stroke and hospital stay is significantly higher in patients with impaired carbohydrate metabolism.Insulin resistance markers are associated with a variety of perioperative characteristics, but according to multivariate analysis, only free fatty acids and HOMA-IR were independent predictors of hospitalacquired complications and long-term hospital stayAim. To analyze insulin resistance markers and their association with the preoperative outcome and in-hospital complications of coronary bypass grafting (CABG) in patients with type 2 diabetes mellitus (DM 2), prediabetes and normoglycemia.Methods. The study included 383 consecutive patients undergoing CABG at the same center. Glycemic status, free fatty acids (FFA), fasting insulin, glucose, lipid profile of all patients were determined before surgery and the following insulin resistance indices (IR) were calculated: HOMA-IR (Homeostasis Model Assessment of Insulin Resistance), QUICKI (Quantitative Insulin Sensitivity Check Index), Revised QUICKI, McAuley. Patients were divided into 2 groups: the group that included patients with carbohydrate metabolism disorders (CMD), type 2 diabetes mellitus and prediabetes (n = 192), and the group of patients without CMD (n = 191). Perioperative characteristics of patients, postoperative complications and their association with insulin resistance markers were analyzed.Results. FFA and calculated indices of insulin resistance such as HOMA-IR, QUICKI, RevisedQUICKI, and McAuley correlated with the following perioperative characteristics: the duration of surgical intervention and cardiopulmonary bypass, lipid levels, coagulation index, left ventricular dimension and myocardial diastolic function, etc. The analysis of in-hospital complications revealed that the frequency of postoperative stroke (p = 0.044) and hospital stay after CABG >30 days (p = 0.014) was significantly higher in patients with CMD. According to the results of multivariate analysis, the predictors of the composite endpoint (hospital stay after CABG>10 days and/or significant perioperative complication) were as follows: female sex (odds ratio (OR) 2.862, 95% confidence interval (CI) 1.062-7.712, p = 0.036); age (OR 1.085, 95%CI 1.027–1.147, p = 0.003); duration of cardiopulmonary bypass (OR 1.146, 95%CI 1.008–1.301, p = 0.035); body mass index (OR 1.125, 95% CI 1.035–1.222, p = 0.005), left atrial dimension (OR 5.916 95% CI 2.188–15.996, p<0.001); any CMD (OR 1.436, 95%CI 1.029–2.003, p = 0.032), type 2 DM (OR 2.184, 95%CI 1.087–4.389, p = 0.027), FFA levels (OR 5.707, 95%CI 1.183–27.537, p = 0.029) and HOMA–IR index (OR 1.164, 95%CI 1.025–1.322, p = 0.019).Conclusion. FFA, HOMA-IR, QUICKI, Revised-QUICKI, and McAuley correlate with a variety of perioperative characteristics of patients undergoing CABG, but multivariate analysis revealed that only FFA levels and the HOMA-IR can be used as predictors of in-hospital complications and prolonged hospital stay.

Туберкулезный спондилит грудопоясничной локализации: выбор оптимального метода хирургического лечения на основе систематизированного обзора литературы

Introduction Tuberculous spondylitis is the most common extrapulmonary tuberculosis. The thoracolumbar lesion due to tuberculous spondylitis is one of the most difficult locations for surgical treatment. Analysis of the recent literature shows a limited amount of data on the results of various current surgical reconstruction techniques. Purpose To review the literature on surgical treatment of thoracolumbar tuberculous spondylitis published during the last five years and judge upon an optimal method. Materials and methods A systematic literature review was performed of the sources from eLibrary, PubMed, Cochrane Library databases. Inclusion criteria: etiologically verified tuberculous spondylitis of thoracolumbar location, follow-up ≥ 1 year, patients older than 18 years. Twenty-one studies that summarize 1,209 cases were selected. Patients were divided into three groups depending on the method of spinal reconstruction (group 1 – ventral approach, group 2 – combined approach, group 3 – dorsal approach). Surgical indicators, correction of kyphotic deformity and its dynamics in the long-term period, rates of complications and the length of hospital stay were analyzed. Results and discussion Blood loss and duration of the intervention were significantly lower in the reconstruction of the thoracolumbar spine from the dorsal approach (599.6 ± 195.1 ml and 196.3 ± 35.6 min). Correction of kyphotic deformity from posterior and combined approaches was higher than in the reconstruction from the ventral approach (64 and 69 %, respectively). At the same time, an inverse proportional dependence of the degree of correction loss in the long-term period was revealed, which was higher with anterior fusion (7.3° ± 1.7° according to Cobb). The duration of hospital stay was shorter in patients with reconstructions from the dorsal approach (13.7 ± 8.2 days). The rate of complications in group 3 was significantly lower (p < 0.0001), while the assessment of their structure indicates prevalence of neurological deficits in dorsal reconstructions, while in ventral and combined reconstructions, infectious complications, pneumothorax, and chronic pain syndrome in the area of autologous costal graft harvesting. Conclusion The optimal method of surgical treatment of thoracolumbar tuberculous spondylitis is a three-column reconstruction from the dorsal approach. The advantages of the method are a decrease in the rate of postoperative complications, a reduction in the duration of inpatient treatment, surgical blood loss and duration of surgical intervention.

Incidence and risk factors of venous thromboembolism in the perioperative period of spine surgery at a tertiary care hospital

Objectives: Spine surgery is considered a moderate risk for developing venous thromboembolism (VTE). To the best of our knowledge, no study has been done to determine the incidence of VTE in our local population. We aimed to study the incidence of VTE and determine the factors associated with developing VTE post-spine surgery. Methods: A retrospective study analyzed 800 adult patients who had undergone elective or emergency spine surgery. The variables included were demographic data, diagnosis, “or trauma if applicable,” type and duration of surgical intervention, and length of hospital stay. In addition, two procedures were used to diagnose VTE, whether it was a pulmonary embolism (PE) or deep vein thrombosis (DVT) pre- and postoperatively. Spiral computed tomography was used to detect PE, whereas duplex ultrasonography was used to confirm DVT. Finally, all patients received post-operative DVT prophylaxis except for cervical spine patients. Results: Eight hundred patients were included in the study. The overall incidence of VTE was 4.1%. The lumbar spine was the most common location operated on. Increasing age and length of hospital stay were both significantly associated with the development of VTE. Furthermore, cervical spine surgery had a lower incidence of VTE than other locations, with a statistically significant difference. Finally, non-ambulatory patients had a higher risk of VTE than patients who could ambulate postoperatively, with a statistically significant difference. Conclusion: The incidence of VTE after spine surgery is considered low but carries high morbidity and mortality rates. Increased age and prolonged hospital stay increase its risk, while early ambulation lowers it. Prophylactic measures against VTE are highly recommended, especially amongst high-risk patients.

Transaxillary hemithyroidectomy and parathyroidectomy: mastering the technique

Background. The relevance of endoscopic interventions on the thyroid and parathyroid glands is beyond doubt, and this explains the interest in this promising choice of surgical approach both among surgeons and patients who want to avoid a scar on the neck.Aim. To evaluate the first results of own endoscopic interventions in patients with diseases of the thyroid and parathyroid glands.Materials and methods. In the Research Institute of KCH N 1 named after prof. S.V. Ochapovsky from December 2020 to April 2022, 23 hemithyroidectomies and 8 paraadenomectomies were performed using endoscopic techniques for benign neoplasms of the thyroid and parathyroid glands. All patients in the preoperative period underwent ultrasound, TAPB + CI (for thyroid pathology), and the hormonal background was studied. Indications for endoscopic hemithyroidectomy in 18 cases were colloid goiter, in 5 cases — follicular adenoma. The indication for endoscopic paraadenomectomy in all cases was primary hyperparathyroidism. We used endoscopic three-port axillary-mammary gas access. Under the ETN, an incision was made along the outer edge of the pectoralis major muscle (m. pectoralis major). Carbon dioxide was injected into the pancreas using a Verish needle. A 5 mm port was inserted along the edge of the areola. Another 10 mm trocar was installed at the attachment points (m. pectoralis major).Results. The average operation time was 190.4 minutes for endoscopic hemithyroidectomy and 78.6 minutes for endoscopic paraadenomectomy. With the increase in the number of performed operations, there was a decrease in the duration of surgical interventions. In two cases in patients after hemithyroidectomy, seromas up to 20 ml in volume were noted in the postoperative period, which required puncture interventions (once).Conclusion. Endoscopic interventions on the thyroid and parathyroid glands from axillary access are a safe method of surgical intervention, and the cosmetic result is an indisputable advantage of this method.

Experience of liver transplantation in the regional clinical hospital

The purpose of the study is to summarize the first experience of liver transplants. Material and methods. Liver transplantation was performed at the Regional Clinical Hospital. 5 liver transplants from a posthumous donor were performed. Based on the available data, the analysis was carried out according to the following criteria: gender, age, MELD- Na index, cause of liver cirrhosis, method of liver transplantation, duration of surgery, postoperative complications, average bed-day, outcome. Results. In total, 5 liver transplants were performed from a posthumous donor. Among the patients there was 1 man and 4 women. The age of men is 41 years, women are 55.4 ± 9.2 years on average. The MELD- Na index is from 15 to 28, on average 17.8 ± 5.1. When transplanting a cadaveric liver, the method of classical orthotopic liver transplantation was used in 4 cases, in one the piggyback technique was used. The duration of surgical intervention in minutes averaged 394 ± 17.4. Postoperative complications on the Clavien-Dindo scale ranged from I to IIIb. The average bed-day of the patient’s stay in the hospital is 20.2 ± 8.9, including 6.2 ± 1.7 days in the intensive care unit. In all 5 cases, the outcome of liver transplantation is satisfactory. Conclusion. The first results of liver transplantation on the basis of the Regional Clinical Hospital showed that performing such a level of operations is possible in a multidisciplinary medical institution.
