COMPLICATIONS OF CONSERVATIVE AND SURGICAL TREATMENT OF FRACTURES OF THE MANDIBULAR CONDYLAR PROCESS (LITERATURE REVIEW)

One of the most pressing problems in modern maxillofacial surgery is the treatment and rehabilitation of patients with fractures of the condylar process of the mandible. According to various statistical data, the incidence of fractures at this site is 19-37%, and these fractures are the most controversial in terms of diagnosis and treatment. In recent years, there has been an increase in severe forms of mandibular condyle fractures: bilateral, combined, intra-articular, leading to serious complications that affect the functioning of the temporomandibular joint. The data obtained indicated the need for a detailed study of this pathology in order to make a qualitative diagnosis and improve the available treatment methods. The aim of the study – to analyse and summarise current data from the scientific literature on possible complications in the treatment of the condylar process fractures of the mandible. Materials and methods. The bibliosemantic method was used to clarify the state of the problem, to study the analysis of the results of previous scientific research based on the literature sources and electronic resources. Results and discussion. The management of patients with mandibular condylar fractures is widely discussed in the literature due to their high prevalence, but there is still no consensus on the optimal management of patients with this pathology. To date, there are many studies that highlight certain complications of conservative and surgical treatment, but they are not generalised or systematised. Conclusions. Summarizing, we can conclude that complications occur during both conservative and surgical treatment of patients with mandibular condyle fractures. Complications are most often associated with incomplete diagnosis, incorrect choice of treatment method, and depend on the method of access and fixation in surgical treatment.

Identifying factors related to delayed neck metastasis after surgical treatment in patients with oral squamous cell carcinoma.

General treatment of oral squamous cell carcinoma (OSCC) is surgical treatment with or without neck dissection. Although the incidence of delayed neck metastasis is rare, it may occur after the surgery and is known to be the most important factor in the prognosis. The purpose of is study is to evaluate the clinical and histopathological factors associated with delayed neck metastasis case among patients. A total of 195 patients who underwent surgical treatment for OSCC from 2016 to 2022 were investigated. Among them, delayed neck metastasis (DNM) was analyzed. The criterion for delayed neck metastasis was a newly developed neck lesion after the primary operation without neck dissection in cN0 necks. To identify the correlation between prognostic factors and the incidence of delayed neck metastasis, χ2 analysis with phi correlation and Cramer's V test was performed. Cumulative survival rates (CRS) were compared between the groups with the incidence of DNM and without DNM. Also, the log rank test for CSR and Cox proportional hazard model was analyzed to estimate the significance of the CSR and confirm the correlations between prognostic factors and DNM. Among 195 patients, 14 were discovered to have DNM. The primary tumor locations were the tongue (n = 5), floor of the mouth (n = 2), mandibular gingiva (n = 1), maxillary gingiva (n = 4), retromolartrigone (n = 1), and buccal mucosa (n = 2) each. The cases consisted of TNM stage I (n = 1), stage II (n = 3), stage III (n = 3), and stage IV (n = 8), respectively. The result of the χ2 analysis identified a correlation between positive neck (p = 0.01), depth of invasion (p = 0.09), radiation therapy (p = 0.003), and DNM. Groups without DNM showed better prognosis compared to groups with DNM. Regarding positive neck, depth of invasion, and radiation therapy, only depth of invasion showed significance in CSR analysis. DNM after surgical treatment of OSCC is a rare event, and few were found in a review of the literature. Also, many prognostic factors have been suggested but controversial. However, in our study, some prognostic factors have been identified to have a significant correlation with the incidence of DNM, and analysis of such factors provides important information predicting neck metastasis and the prognosis.

The utility of a CT grading scale in deciding on surgical intervention for patients with suspected small bowel obstruction

BackgroundA grading system was developed for computerized tomography (CT) scans evaluating patients with suspected small bowel obstruction (SBO). We hypothesized that patients with a higher grade of suspected SBO on CT scan would be more likely to require surgical intervention. MethodsRetrospective chart review of patients who presented to the Emergency Room (ER) who had a CT of the abdomen and pelvis for suspected SBO. Patients were divided into 5 groups: Grade 1 (SBO unlikely), Grade 2 (probable partial or early SBO), Grade 3 (probable high grade SBO), Grade 4 (SBO with changes concerning for ischemia) and Not Graded. ResultsThe CT scans of 655 patients were graded. Of the 22 patients with a grade 1 SBO, only 1 went for surgery (4.5 %). For grade 2 patients, 23 out of 299 had an operation (7.7 %), for grade 3 it was 84 out of 299 (28.1 %) and for grade 4 SBO, 25 out of 35 patients (71.4 %) had surgery. The p value is <0.00001. The three most common intraoperative findings were SBO obstruction from adhesions alone (48 % of cases), followed by incarcerated hernias (12 %) and ischemic bowel (9 %). Only 8 cases out of 133 operations (6 % of total) had no findings at time of surgery other than dilated bowel. ConclusionsThe CT grading scale for SBO developed at our institution shows excellent correlation between grade and going for surgery, with few negative results, and can be a useful tool among other factors for general surgeons when deciding whether or not to operate on a patient with suspected SBO.

Use of Densitometric Indicators Free DICOM-Viewer’s and Digital Data Processing Programs in Surgical Treatment of Patients with Pulmonary Tuberculosis

Objective — to determine the potential of using freely distributed specialised digital data processing programs and free DICOM-viewers for assessing densitometric indicators obtained from computed tomogra­phy of the thoracic organs. This aims to facilitate the planning of surgical treatment for patients with pulmonary tuberculosis and to substantiate methods for preventing pulmonary-pleural complications. Materials and methods. A retrospective analysis was conducted on the examination and treatment results of 103 patients with specific tuberculous lesions of the lungs. Histological examination of the resected material determined the degree of the specific inflammatory process in the affected tissue, based on which patients were categorised into groups. Group I included 32 patients with low activity of the specific inflammatory process, Group II comprised 37 patients with moderate activity and Group III included 34 patients with high activity. Using five common digital processing programs, densitometric indicators of the thoracic organs' structures were obtained. The accuracy of density indicators displayed by these programs was analysed in comparison with the results of histological examinations. Results and discussion. According to our data, the densitometric indicators obtained using free DICOM-viewers and digital data processing programs show a strong correlation with the reference standard and among themselves. The determined density indicators have a strong association with histological findings of emphysema and fibrosis of the lung parenchyma. These indicators are reliably identified both in cases of high activity of specific inflammation in the lung parenchyma and in inactive processes, allowing for patient stratification. It was found that the average density values of the mediastinal lymph nodes in cases of inactive specific inflammatory processes in 80 % of cases were (54.4 ± 17.8) HU. Values of (15.0 ± 2.5) HU characteri­sed high activity of specific inflammatory processes and the progressive phase of the disease. Clinically, 89 (86.4 %) of the patients with significant deviations in the densitometric density indicators of the lung parenchyma from the norm experienced prolonged air leakage in the postoperative period. In 96 (93.2 %) patients with altered density of mediastinal lymph nodes, prolonged postoperative exudation through pleural drains was noted. Patients with altered densitometric indicators had complicated intraoperative and postoperative courses. Changes in the density of the lung parenchyma detected on computed tomography of the thoracic organs were confirmed in 96.1 % of cases by histological examination of the resected material. These changes were reliably detected by all the programs studied. Conclusions. Densitometric indicators obtained using DICOM-viewers and digital data processing programs enable the planning of surgical treatment for patients with pulmonary tuberculosis and the reasoned application of methods to prevent pulmonary-pleural complications.

A systematic review and meta-analysis of operative versus non-operative management for first time traumatic anterior shoulder dislocation in young adults

Background The most appropriate management following primary traumatic anterior shoulder dislocation in young adults is unclear. This systematic review and meta-analysis evaluated operative versus non-operative management. The primary outcome measure was re-dislocation rate, in contrast to the often reported ‘recurrent instability’, which includes subjective instability. Methods Our review was prospectively registered with PROSPERO (CRD42022322600) and reported as per PRISMA guidelines. Selection criteria included mean age of participants between 15 and 25 and minimum follow-up of 1 year. Results 21 studies meet the inclusion criteria with 5142 patients included. The mean age of patients was 23, with 87% male. There was a median of 54 patients per study and a mean follow up of 46 months per study. The mean re-dislocation rate was 16.08% in the operative group and 24.84% in the non-operative group. In the subgroup meta-analysis, including only RCTs, comparing arthroscopic stabilisation vs non-operative there was an odds ratio of 0.09, strongly favouring intervention. Discussion This systematic review found the literature available supports surgical intervention in patients under the age of 25, in order to reduce re-dislocation. However, there is a lack of cost-effectiveness data to support these findings, and this should be an area of future research.

Case of successful treatment of spinal infection in a patient with high comorbidity and septic manifestations

The study presents a clinical case of complex treatment of a patient with high comorbidity (Charlson comorbidity index = 6 points) who had severe sepsis (SOFA score = 8 points) with multiple foci of pyogenic infection (spinal epiduritis, paravertebral and subdural abscesses, purulent meningitis, bilateral lower lobe pneumonia). The syndrome-based approach with the use of minimally invasive approaches in the early stages (no later than 12 hours from the onset of clinical manifestations of the disease) ensured a favorable outcome. Based on the results of surgical treatment, a conclusion was made about the tactics of surgical treatment in patients with spinal infection against the background of sepsis.

The effectiveness of minimally invasive surgical techniques for treating patients with chronic venous insufficiency in the stage of trophic disorders: comparative study

Introduction. Despite the active introduction of minimally invasive techniques into modern phlebology, the problem of surgical treatment of chronic venous insufficiency (CVI) in the stage of trophic disorders is still far from being finally resolved, especially problems of horizontal reflux. Aim. Тo comparatively evaluate the results of using various tactics of minimally invasive surgical treatment in patients with lower extremitiesʹs CVI in the stage of trophic disorders.Materials and methods. A study at 139 patients with CVI at the stage of trophic disorders was carried out. Group 1 (n = 79) included patients who underwent endovasal laser coagulation of the trunks of the great and small saphenous veins (GSV and SSV) with microfoam sclerotherapy of varicose perforating veins. In group 2 (n = 60) – method of intervention was determined by the diameter of Cockettʹs perforants.Results. Indicators of the early postoperative period in the study groups were comparable. After 2 months, no cases of relapse in the GSV and SSV were registered. Recurrence of horizontal reflux was observed only in 6 (7.6%) people in group 1. In long-term postoperative follow-up, decrease in the severity of the disease according to the VCSS scale was found in both groups (p &lt; 0.001). The persistence of pathological reflux along was observed in 16 (22.5%) patients of group 1. Moreover, in 62.5% and 68.75% cases of relapses, the perforants had, respectively, a large diameter and high blood flowʹs speed.Discussion. In general, minimally invasive techniques used demonstrated comparable clinical results and high efficiency. At the same time, the importance of preoperative assessment and taking into account the properties of perforants has been proven.Conclusion. The claimed method should be considered as an effective and safety method of obliteration of incompetent perforating veins at severe forms of CVI.

Efficiency and productivity gains of robotic surgery: The case of the English National Health Service.

This paper examines the effect of new medical technology (robotic surgery) on efficiency gains and productivity changes for surgical treatment in patients with prostate cancer from the perspective of a public health sector organization. In particular, we consider three interrelated surgical technologies within the English National Health System: robotic, laparoscopic and open radical prostatectomy. Robotic and laparoscopic techniques are minimally invasive procedures with similar clinical benefits. While the clinical benefits in adopting robotic surgery over laparoscopic intervention are unproven, it requires a high initial investment cost and carries high on-going maintenance costs. Using data from Hospital Episode Statistics for the period 2000-2018, we observe growing volumes of prostatectomies over time, mostly driven by an increase in robotic-assisted surgeries, and further analyze whether hospital providers that adopted a robot see improved measures of throughput. We then quantify changes in total factor and labor productivity arising from the use of this technology. We examine the impact of robotic adoption on efficiency gains employing a staggered difference-in-difference estimator and find evidence of a 50% reduction in length of stay (LoS), 49% decrease in post-LoS and 44% and 46% decrease in postoperative visits after 1year and 2years, respectively. Productivity analysis shows the growth in radical prostatectomy volume is sustained with a relatively stable number of urology surgeons. The robotic technique increases total production at the hospital level between 21% and 26%, coupled with a 29% improvement in labor productivity. These benefits lend some, but not overwhelming support for the large-scale hospital investments in such costly technology.

Surgical Treatment of Neuropathic Chronic Postherniorrhaphy Inguinal Pain: A Systematic Review and Meta-Analysis.

Background/Objectives: Neuropathic chronic postherniorrhaphy inguinal pain (CPIP) is a serious adverse outcome following inguinal hernia repair surgery. The optimal surgical treatment for neuropathic CPIP remains controversial in the current literature. This systematic review aims to evaluate the effectiveness of various surgical techniques utilized to manage neuropathic CPIP. Methods: The electronic databases Medline, Embase, Web of Science, Cochrane Central, and Google Scholar were searched. Inclusion criteria were defined to select studies reporting on the efficacy of surgical interventions in patients with neuropathic CPIP. The primary outcome was postoperative pain relief, as determined by postoperative numerical or nonnumerical pain scores. Results: Ten studies met the inclusion criteria. Three surgical techniques were identified: selective neurectomy, triple neurectomy, and targeted muscle reinnervation. Proportions of good postoperative results of the surgical techniques ranged between 46 and 88 percent. Overall, the surgical treatment of neuropathic CPIP achieved a good postoperative result in 68 percent (95% CI, 49 to 82%) of neuropathic CPIP patients (n = 244), with targeted muscle reinnervation yielding the highest proportion of good postoperative results. Conclusions: The surgical treatment of neuropathic CPIP is generally considered safe and has demonstrated effective pain relief across various surgical techniques. Targeted muscle reinnervation exhibits considerable potential for surpassing current success rates in inguinal hernia repair surgery.

Two-Year Functional Outcomes of Nonsurgical Treatment in Concomitant Anterior Cruciate Ligament and Medial Collateral Ligament Injuries: A Case-Control Study.

The anterior cruciate ligament (ACL) is a common knee injury in high-intensity sports, which can cause early career loss in young athletes. Concomitant damage to other knee stabilizers may occur, such as the medial collateral ligament (MCL). Recent studies have shown that knee stability can increase without surgical intervention in patients with ACL and MCL injuries. Regarding the importance of functional tests in return to exercise prediction, this study aims to measure nonsurgical approach's long-term outcome for concomitant ACL and MCL injuries with a focus on functional tests. This is a case-control study with a 2-year follow-up. The case group consisted of patients who had provided written consent and completed their 2-year follow-up, and the control group was made up of healthy people who did not have any knee medical conditions and were matched by age, gender, and activity level. Physical examinations, Tegner and International Knee Documentation Committee questionnaires, and knee magnetic resonance imaging were conducted, and functional performance tests were performed after a 10-minute warm-up. Lody's index (the ratio of injured-to-uninjured knee results) was calculated. The data were analyzed using independent t-test, one-way analysis of variance, chi-squared test, and Fisher's exact test. The study involved 11 patients in each concomitant ACL and MCL injury cases and healthy control groups with a mean age of 32.4 and 28 years, respectively. None of the patients reported knee instability symptoms in the 2-year follow-up. More than half of the patients continued their sports field without reinjury, with no significant difference in activity levels between case and control groups. The 6-meter hop test and single-leg hop test showed no significant difference between case and control groups (p-value: 0.326, 0.859), and no significant difference was observed in the three Carioca, cocontraction, and Shuttle tests in the 2-year follow-up. Functional tests in ACL and MCL injuries revealed normal outcomes, implying a nonsurgical approach for patients with proximal ACL tears, better knee stability, and no significant differences between the injured and control groups.

Extent of surgery for unilateral papillary thyroid cancer with nonsuspicious contralateral nodules by ultrasound.

The discussion about surgical treatment of patients with papillary thyroid cancer(PTC) has been an ongoing issue, which is mainly focused on characteristics of tumor, but rarely on nonsuspicious contralateral nodules. We aimed to compare recurrence-free survival(RFS)/progression-free survival(PFS) of unilateral PTC patients with nonsuspicious contralateral nodules after different extents of surgery. Unilateral PTC patients with nonsuspicious contralateral nodules underwent surgery from 2015 to 2017 were enrolled. The association between surgical extent and RFS/PFS was analyzed by Kaplan-Meier method and Cox proportional hazards model. A total of 1293 PTC patients (595[46.0%]TT,523[40.4%]lobectomy+nodule enucleation(LNE),175[13.5%]lobectomy) were analyzed. Patients with a greater surgical extent were more likely to be older, have a greater multifocality of the tumor and contralateral nodules, larger contralateral nodules and primary tumors, and more micro extrathyroidal extension (P < 0.05). After a median follow-up of 45 months, significant growth(>3 mm) was identified in 24 (4.6%) and 19 (10.9%) patients in the LNE and lobectomy group, 7 (1.2%), 14 (2.7%) and 11 (6.3%) structural recurrences and 7 (1.2%), 11 (2.1%) and 7 (4.0%) progression in disease were identified in the TT, LNE and lobectomy groups, respectively. Unadjusted and adjusted RFS/PFS were significantly worse for patients treated with lobectomy than for those who underwent LNE or TT(3-year RFS, 95.5%, 98.2% vs. 99.0%; 3-year PFS, 97.9%, 98.9% vs. 99.0%, P < 0.05), but difference in PFS between LNE and TT lost statistical significance (unadjusted P = 0.226, adjusted P = 0.150). Due to subtle changes in nodules and acceptable prognosis, lobectomy is a considerable option for unilateral PTC patients with nonsuspicious nodules, when a similar prognosis to TT is expected, LNE may be an effective alternative to optimize quality of life.

Topical dexamethason effectiveness combined with surgical intervention in patients suffering from chronic subdural hematoma

BackgroundA chronic subdural hematoma (CSDH) is one of the most common neurosurgery operations. This study aimed to evaluate the effect of topical corticosteroids combined with surgery in patients with CSDH. Materials and MethodsThe present study is a clinical trial study on patients referred to hospitals associated with Ahvaz University of Medical Sciences with chronic subdural hematoma in 2019. Patients requiring surgical drainage of chronic subdural hematoma who met the inclusion criteria underwent open craniotomy surgery on the side of the hematoma. A drain was placed in the open craniotomy site. On the third day after the operation, before removing the drain, 40 mg of methylprednisolone sodium succinate was injected through the drain into the subdural space, after which the drain was pulled entirely. Patients were evaluated with the Markwalder Grading Scale (MGS) on the third day, third month, and sixth month after surgery for improved or worsened neurological symptoms. Also, in the third and sixth months after surgery, the patients underwent Computerized Tomography Scan imaging and were checked for recurrence. Results32 patients with CSDH entered the study, including 28 men and four women, with a mean age of 71.62 ± 9.85 years. Moreover, 87.5 % had a unilateral chronic subdural hematoma (uCSDH), and 12.5 % had a bilateral chronic subdural hematoma (bCSDH). Left and right uCSDHs had the same frequency (43. 8 %). After surgery, 26 patients had no postoperative complications, and six patients experienced pneumocephalus. ConclusionTopical dexamethasone injection through the potential CSDH cavity can result in desirable outcomes.

Identification of relapse predictors of IgG&lt;sub&gt;4&lt;/sub&gt;-related sclerosing cholangitis

Introduction. Relapses occur in 30–50% of patients IgG4-related sclerosing cholangitis. Relapses may act an independent risk factor for malignancy development and the need in maintenance therapy for relapse prevention is still uncertain. Thus, studying relapse predictors and developing reliable preventive approaches is an important area of research for this condition.Aim. To determine relapse predictors of IgG4-related sclerosing cholangitis.Materials and methods. A single- center dynamic bidirectional observational study was conducted in patients aged 18 years and older with verified IgG4-related sclerosing cholangitis (n = 32). We searched for possible factors influencing the relapse of IgG4- related sclerosing cholangitis. The development of a prognostic model for the relapse probability was carried out using logistic regression. ROC analysis was used to assess the diagnostic performance of quantitative variables in predicting of relapse.Results. The median follow-up period was 33 (16–60) months. The majority of patients with IgG4-related sclerosing cholan- gitis were male (71.9%), median age was 59 ± 13 years. In most patients, delayed diagnosis (median 10.5 [4.8; 22.5] months) was associated with overdiagnosis of primary sclerosing cholangitis (41.2%) or bile duct malignancy (43.8%). Surgical interventions were performed in 50% of patients. Median serum IgG4 level was 2.70 g/L [1.92; 6.48], and 21.9% of patients had normal serum IgG4 level. Disease relapse developed in 34.4% (n = 11) of patients. Serum IgG4 level before glucocorticosteroid therapy ≥ 2.24 g/L and a delay in diagnosis by ≥ 17 months were associated with the relapse (p = 0.040 and p = 0.049 respectively). Multi-organ involvement, and extrahepatic localization of biliary strictures in the patients with the history of surgical interventions increased the risk of relapse 85 (p = 0.001) and 12 (p = 0.047) fold, respectively. The presence of biliary strictures below the confluence reduced the risk of relapse 7.5 fold (p = 0.032).Conclusions. Possible predictors of IgG4-related sclerosing cholangitis relapse may include multi- organ involvement, intrahepatic and proximal extrahepatic strictures, prior surgical interventions in patients with extrahepatic strictures, high serum IgG4 level, and delayed diagnosis.

Abstract PO5-14-03: Analytical Validation of the StemPrintER Assay in Patients with Breast Cancer

Abstract Discussion: Breast cancer is the most common malignancy diagnosed amongst women, with more the two million new cases identified globally each year. Thus, considerable resources have been devoted to a better understanding of the disease and how to optimize outcomes for patients. Genetics and genomics have become part of routine care with the latter used to inform treatment planning for patients with ER+ breast cancer (ER+ BC). A multitude of assays may be used to determine the need for adjuvant chemotherapy but none of the current tests on the market are guideline-recommended for making decisions related to neoadjuvant chemotherapy, surgery, or radiation. The 24-gene StemPrintER assay was developed to measure the “stemness” of tumors, or how much a tumor behaves like stem cells, which could have important and novel implications for breast cancer treatment planning. The assay has been validated for predicting prognosis using formalin-fixed paraffin-embedded (FFPE) tissue blocks from several clinical cohorts, including TransATAC. The goal of current and future research will be to determine whether the assay can determine the ideal surgical intervention for ER+BC patients. Early in silico work demonstrated a trend toward this predictive capacity for the assay and suggests the assay may be able to identify the benefit of mastectomy versus quadrantectomy. Here, we report on the ability to set up and run the assay in our lab using synthetic oligonucleotides and archival tissue blocks. Methods: Synthetic oligonucleotides and archival FFPE breast cancer tissue were used to set up and analytically validate the assay’s performance in two phases. The initial phase was intended to confirm the individual assay design performance by assessing linearity and precision and the ability to amplify RNA from FFPE, which confirmed compatibility with standard extraction methods. The second phase was intended to determine whether these methods could be implemented to reliably extract and amplify RNA from FFPE &amp;gt;10 years old (range: 10-14 years) in order to generate a StemPrintER score. The assay was run according to standard operating procedures for StemPrintER. Analyses were conducted Python 3.9.12. Results: Two assay runs with duplicate samples for each run using a 7-point dilution series demonstrated linearity (coefficient of correlation, r2) results ranging from 0.978 to 0.999 for each of the 24 genes in the assay. Amplification efficiency was between 100-101% for each gene. Using 14 FFPE samples from patients with triple-negative breast cancer, we demonstrated a consistent extraction yield of RNA from tumor blocks which produced amplification of each of the targets. Analysis of intra- and inter-run precision resulted in coefficients of variation (CV) ranging from 0.2-1.07% and inter-run CV’s ranging from 0.66%-5.56%. Utilizing FFPE &amp;gt;10 years old from ER+BC patients demonstrated that the lab could extract RNA from 100% of samples and amplify the material to obtain binary StemPrintER results. Conclusion: These data demonstrate that StemPrintER can be run reliably on FFPE tissue up to 14 years old. In addition, our laboratory has demonstrated that assay results are highly linear and reproducible. Additional studies are planned to build on preliminary surgical prediction data and determine whether the assay can meet the unmet need of identifying the ideal surgical intervention in patients with early-stage ER+/HER2- breast cancer.

Effectiveness of Surgical Treatment of Patients with Destructive Pulmonary Tuberculosis (Meta-Analysis)

The objective: to study effectiveness of surgical methods for treatment of various forms of destructive pulmonary tuberculosis (meta-analysis).Subjects and Methods. A systematic search was performed in electronic bibliographic databases, including PubMed and Google Scholar. Cohort studies published from January 1, 2019 to June 20, 2023 were selected, those studies were aimed to assess effectiveness of surgical treatment in patients with destructive tuberculosis using resections of various volume. For meta-analysis, 9 studies published in 2019 - 2023 were selected.Results. The effectiveness of comprehensive treatment with resections of various volume in destructive pulmonary tuberculosis patients made 85.3%. The success of surgical treatment in patients with fibrous cavernous pulmonary tuberculosis was somewhat less – 80.3%. At the same time, the incidence of postoperative complications in patients with fibrous cavernous pulmonary tuberculosis was higher and could reach 42.5%, while in the group patients with destructive tuberculosis, it was 27.3%. Some postoperative complications required repeated operations. The ratio of surgeries to patients was the following: 3263 surgical interventions per 1564 patients (average 2.08 surgeries per patient). Hospital lethality among patients with fibrous cavernous pulmonary tuberculosis after surgical treatment was 2.6%, and tuberculosis mortality within 5 years after surgery was 4.8%. The relapse rate among patients with fibrous cavernous pulmonary tuberculosis after surgical treatment was 7.1%.

International Variations in Surgical Quality of Care in Men With Prostate Cancer: Results From the TrueNTH Global Registry.

Functional problems such as incontinence and sexual dysfunction after radical prostatectomy (RP) are important outcomes to evaluate surgical quality in prostate cancer (PC) care. Differences in survival after RP between countries are known, but differences in functional outcomes after RP between providers from different countries are not well described. Data from a multinational database of patients with PC (nonmetastatic, treated by RP) who answered the EPIC-26 questionnaire at baseline (before RP, T0) and 1 year after RP (T1) were used, linking survey data to clinical information. Casemix-adjusted incontinence and sexual function scores (T1) were calculated for each country and provider on the basis of regression models and then compared using minimally important differences (MIDs). A total of 21,922 patients treated by 151 providers from 10 countries were included. For the EPIC-26 incontinence domain, the median adjusted T1 score of countries was 76, with one country performing more than one MID (for incontinence: 6) worse than the median. Eighteen percent of the variance (R2) of incontinence scores was explained by the country of the providers. The median adjusted T1 score of sexual function was 33 with no country performing perceivably worse than the median (more than one MID worse), and 34% (R2) of the variance of the providers' scores could be explained by country. To our knowledge, this is the first comparison of functional outcomes 1 year after surgical treatment of patients with PC between different countries. Country is a relevant predictor for providers' incontinence and sexual function scores. Although the results are limited because of small samples from some countries, they should be used to enhance cross-country initiatives on quality improvement in PC care.

Provider Opinions on Effectiveness of Physical Therapy as Treatment for Glenohumeral Arthritis

IntroductionPhysical therapy (PT) is a described first-line treatment option for glenohumeral arthritis, but its efficacy for treating this spectrum of disease is not well understood. The purpose of this study is to evaluate the opinions of expert providers—orthopedic surgeons and physical therapists—regarding the utility of PT in treating glenohumeral arthritis in different stages of radiographic severity. Our goal is to identify areas of interprofessional majority agreement as well as areas without agreement that warrant further investigation. MethodsA 35-question survey was created and distributed via email to members of the American Shoulder and Elbow Surgeons and the American Society of Shoulder and Elbow Therapists, collecting information on demographics, professional experience, and the perceived benefit of PT for patients with different stages of glenohumeral arthritis based on radiographic severity. Survey responses were analyzed for inter-professional differences in distribution of answer choices as well as for majority agreement statements. Items with > 50% agreement from a professional group were considered statements of majority agreement. Results190 surgeons and 39 physical therapists completed the survey. Surgeons and therapists demonstrated different distribution of answer choices in 25 of the 29 non-demographic related questions (86%). Surgeons and therapists reached the same majority statement in eight items (28%) and reached disagreeing majority statements in four items (14%). They agreed on the benefits of PT for mild arthritis, the benefits of corticosteroid injections, the frequency of strengthening exercises, and that PT failure should not be required for surgical approval in patients with severe arthritis. They disagreed on the whether PT exacerbates symptoms in patients with moderate arthritis, and whether preoperative PT influences postoperative outcomes. ConclusionBoth surgeons and therapists agreed that PT may be less beneficial for patients with more advanced radiographic arthritis and that PT failure should not be required for insurance approval for surgical intervention in patients with severe glenohumeral arthritis. Further research is needed to determine the efficacy of PT for patients with moderate arthritis as well as the utility of preoperative PT for improving postoperative outcomes.

Current aspects of the treatment of combat surgical trauma

Objective. The history of providing assistance to victims with gunshot wounds dates back more than one century, but nevertheless surgical treatment of gunshot wounds is still relevant to this day. High-quality primary surgical treatment of a gunshot wound is the key to a speedy recovery of the patient (N.I. Pirogov). The pathogenesis of gunshot wounds determines the specific tactics of surgical treatment. Gunshot wounds are zonal in nature. According to the results of morphological studies, it can be concluded that a significant part of the changes in the zone of molecular concussion of the wound canal are reversible, and the complexity of pathogenesis and the lack of reliable criteria for assessing the condition of tissues does not exclude the possibility of leaving areas with reduced viability in the wound after treatment. For maximum effect during surgical treatment of gunshot wounds, non-viable tissues should be removed with minimal damage to viable ones. To meet these requirements, it is often impossible to visually assess the boundary between damaged and parabiotic tissues objectively intraoperatively. The use of modern physical methods of wound wrapping and preparing them for plastic closure, such as low-frequency ultrasound, hydrosurgical methods and VAC therapy allows you to radically clean the wound surface with minimal damage to viable tissues and perform plastic closure operations on soft tissue defects at an early date.Purpose of a study: to improve the methods of primary surgical treatment in patients with combat surgical trauma using low-frequency ultrasound.Material and methods. Our study is based on the analysis of the treatment results of 93 patients aged 10 and 70 years old. All patients had combat surgical trauma of various etiology and localization. Of these, 36 (38.7%) patients in main group underwent ultrasound cavitation of the wound canal and wound defects during primary surgical treatment (PST), followed by primary or primary delayed plastic surgery within a period not exceeding 48 hours after PST. Methods of plastic wound closure were both flaps with axial circulation and autodermotransplantation. In the remaining 57 (61.3%) patients of comparison group, primary surgical treatment was not performed, or was performed at the stages of evacuation, with further conservative treatment. Upon admission to the clinic, he underwent secondary surgical treatment, opening of purulent lumps, as well as staged necrectomies, while wound plastic surgery was performed after wound cleansing and was mainly represented by autodermotransplantation.Results. It was revealed that in the main group, the treatment time of patients in the main group was reduced by 2 times compared with the comparison group (16.3 and 34.2 bed days, respectively). The effectiveness of engraftment of autodermotransplants was evaluated according to V.I. Petrov's scheme. Lysis of autodermotransplants was noted 1.9 times less frequently in the main study group. It was also noted that there were no purulent complications in main group, unlike comparison group – 20.6%, the number of marginal necrosis was 2.6% in main group and 22.4% – in comparison group, lysis of autodermotransplanates in main group was 7.8%, in comparison group – 13.8%.Conclusion. This study allows us to conclude that the advantage of using ultrasonic cavitation during the usual surgical treatment of gunshot wounds followed by primary or primary delayed plastic surgery.

Analysis of the Clinical Value of Surgical Treatment and Postoperative Anti-Infection Treatment of Acute Suppurative Appendicitis

Objective: To explore the clinical value of surgical treatment and postoperative anti-infection treatment for acute suppurative appendicitis. Methods: A total of 116 patients with acute suppurative appendicitis were enrolled in this study. The collection period was from December 2021 to December 2023. The patients were randomly grouped into a control group (surgical treatment) and an observation group (surgical treatment and postoperative anti-infection treatment), of 58 patients each. At the end of the treatment, the results of each index of the two groups were compared. Results: The length of hospitalization time, exhaust time, and incidence of complications in the observation group were shorter than those of the control group (P &lt; 0.05). The total effective rate of the observation group was higher than that of the control group (P &lt; 0.05). Conclusion: It is crucial to perform anti-infective treatment promptly after surgical treatment in patients with acute suppurative appendicitis. It can effectively prevent the occurrence of complications and improve the clinical efficacy. Hence, it is worthy of research and promotion.
