Can Artificial Intelligence Help Us in the Evaluation of Coronary Artery Calcification Scores by Acting as a Prognosticator in Patients That Are Operated on Due to Non-Small Cell Lung Cancer? A Pivotal Study.

Background: Non-small cell lung cancer (NSCLC) is the leading cause of death from malignancies, and surgical resection is the most effective form of treatment. Coronary artery disease (CAD) is a common comorbidity in patients with NSCLC. A coronary artery calcium (CAC) score correlates with the extent of CAD. We aimed to test whether an automated assessment of CAC scores helps to identify the population of patients with a higher risk of postoperative complications and worse overall survival (OS) after the surgical treatment of NSCLC. Methods: In this retrospective cohort study, the data of the patients who were surgically treated for NSCLC were matched with the reassessed preoperative CT images. The postoperative complication rates and overall survival were analyzed. The CAC score was evaluated automatically using the Syngo.via Siemens Healthcare software. Cardiac age was assessed according to Hoff et al. 2001. The prognosticators of postoperative complications and of OS were tested. Results: The data of 193 patients with complete data, an adherence to the inclusion and exclusion criteria, and that were operated between 2018 and 2019, were included. Cardiac age was a predictor of the cardiovascular and pulmonary complications rate (95%CI -0.007-0.203, p = 0.066, beta coefficient 0.098). In a multivariable stepwise regression analysis, operative access was a predictor of cardiovascular and pulmonary complications (95%CI -0.290--0.111, p < 0.001, beta coefficient -0.200), cardiovascular complications (95%CI -0.161--0.022, p = 0.011, beta coefficient -0.036), and the general complication rate (95%CI -0.370--0.194, p < 0.001, beta coefficient -0.286). Kaplan-Meier curves were separated in the survival analysis of groups of patients with a cardiac age 0-69 years vs. an age of 70+ (92 vs. 92 patients) (in Cox regression analysis, HR = 1.678, 95%CI 0.847-3.292 p = 0.138). Conclusions: An automated CAC score assessment may be a potential and clinically meaningful prognosticator of both postoperative complications and OS in patients that are operated on due to NSCLC. Further studies are required.

Krankenhaussterblichkeit bei Patienten mit und ohne Demenz

Background: Studies reported a higher in-hospital mortality in patients living with dementia (PlwD) with limited evidence across age groups, clinical departments and admission diagnoses. Study aim was to compare the in-hospital mortality rate of PlwD with non-demented controls across groups, clinical departments and admission diagnoses. Methods: This case-control study included patients aged ≥ 60 years hospitalized in one of 36 German hospitals between January 2019 and July 2023. PlwD were matched to non-demented controls. The associations between dementia and in-hospital mortality across groups were assessed using univariable logistic regression analyses. Results: 29,203patients with and 29,203 without dementia were included (mean age: 84 years, 60% female). PlwD had a significantly higher in-hospital mortality rate than non-dementia controls. The excess mortality rate was highest in the youngest age group (60–70 years), decreased with age, and became non-significant in the oldest age group (≥ 90 years). Significant differences were found for digestive system, cardiovascular and cerebrovascular disorders, endocrine, nutritional and metabolic diseases, and pneumonia, as well as for internal medicine and gastroenterology departments. Conclusion: The excess mortality rate was highest in younger age groups, where the general mortality and complication rate is relatively low in the general population. Appropriate approaches are needed.

Escalating Health Crisis: Dissecting Mortality Causes and Trends Among Indigenous Populations in Northeast Brazil.

In Northeast Brazil, the poorest region of the country, indigenous communities face critical health care challenges. Despite legal entitlements to the Unified Health System (SUS), systemic barriers persist, exacerbating health disparities and mortality. This ecological study analyzed mortality trends and causes of death within the Special Indigenous Sanitary District (DSEI) Alagoas-Sergipe over a decade. Data on deaths from 2012 to 2022 were obtained from the Indigenous Health Secretariat. Causes of death were classified into 13 categories. Mortality rates per 1,000 indigenous inhabitants were calculated, and trends were analyzed using the Mann-Kendall test. The study also compared causes of death by age group. Mortality rates ranged from 3.3 to 5.2 per 1,000, showing a moderate upward trend over time (τ = 0.5, p = 0.042). Predominant causes included heart and vascular disorders (24.3%), external causes (12.4%), respiratory issues (11.1%), and infections (10.9%). About one-third of pediatric deaths were associated with general neonatal complications. This study highlights increasing mortality in indigenous communities in Northeast Brazil. The predominant causes of death reflect broader public health concerns. These trends emphasize the urgency for more effective, culturally sensitive public health policies and improved health care access.

Perioperative Mechanical Circulatory Support for Cardiac Assistance in Thoracic Surgery: A Scoping Review Protocol.

Over the past decades, the number of cardiac patients (e.g., with advanced heart failure or existing cardiovascular comorbidities that expose them to a heightened risk of acute cardiovascular decompensation) requiring noncardiac surgery is rising. For this patient population, potentially curative surgical treatments may be denied due to their prohibitive perioperative risk. Around 30% of patients undergoing general thoracic surgery experience cardiovascular complications of varying severity that may ultimately result in refractory heart failure and/or hemodynamic instability. In both these scenarios, perioperative implantation of temporary mechanical circulatory support (tMCS) may improve patient outcomes by both expanding preoperative surgical eligibility criteria and enabling safer management of unexpected periprocedural complications. This scoping review seeks to summarize the current existing evidence on the role of tMCS for cardiac assistance in thoracic surgery and provide a thorough overview. We will perform a scoping review adhering to the Joanna Briggs Institute (JBI) methodology and the extension for Scoping Reviews of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis checklist (PRISMA). We will carry out a comprehensive search of several online databases to identify studies on the perioperative implantation of tMCS in patients undergoing thoracic surgery to provide cardiac assistance either due to their heightened preoperative cardiac risk (pre-emptive tMCS) or for acute cardiac failure due to inherent surgical complications (bail-out tMCS). Standardized forms will be employed to perform data charting and extraction. Retrieved studies will be presented through a narrative synthesis following initial categorization, supplemented by descriptive statistical analyses of quantitative data if adequate inter-study homogeneity is observed and further complemented by figures and tables. The planned scoping review aims to assess the safety and feasibility of perioperative implantation of tMCS in patients undergoing thoracic surgery either to mitigate their heightened cardiovascular risk or as a rescue strategy in the event of life-threatening surgical complications. It will identify knowledge gaps, offer direction for future research, and improve clinical practices within the field.

Thirty-Day Postoperative Complications after Spinal Fusion in Patients with Spinal Metastasis

Objective: Decompression with instrumented fusion is a common approach for treating spinal metastatic disease. However, in many cases, poor bone quality and compromised general condition increase the likelihood of mechanical failure and other complications. This study investigated complications, including those related to surgery, following decompression and fusion in patients with spinal metastatic disease.Methods: A study at a single tertiary medical center focusing on surgical details and perioperative complications was performed on 35 patients who underwent spinal surgery due to metastatic spinal disease based on a review of a prospective database. Data on patients' underlying conditions and the status of the primary tumors were collected, and various complications that occurred within the first month after surgery were analyzed.Results: During the study, 35 patients (mean age, 66.5 years; 26 men) were enrolled. The most frequent primary cancers were lung (34%) and prostate cancer (17%), followed by liver and breast cancer and others. The overall complication rate was 37% (14% surgery-related complications, 23% general complications). In all cases, surgery was performed due to lower extremity weakness, and 59% of patients showed improvements in motor function after surgery. Furthermore, 23% of patients regained the ability to walk.Conclusion: Surgery for spinal metastasis is frequently performed as an emergency due to the severity of symptoms such as lower extremity weakness. Despite a high risk of acute complications, the procedure has significant benefits, including improvement in weakness and recovery of walking ability. Therefore, proactive treatment using appropriate surgical techniques is recommended.

Characteristics and outcomes of inpatients aged 85 and older with thoracolumbar vertebral fractures: impact on hospital stay and mortality.

There is a gap in evidence about medical outcomes in oldest-old patients (aged 85 and older) with vertebral fractures (VFs). The aim of this study was to evaluate the impact of patient and fracture characteristics on "short-term" hospital outcomes. All patients aged ≥ 85 presenting an acute or subsequent VF at our single level I spine center between 2019 and 2021 requiring hospital treatment were included. The data collection was conducted retrospectively. The primary parameters of interest were length of stay (LOS) and in-hospital mortality. Further outcome parameters were the occurrence of general (non-operative) complications and Intensive Care Unit (ICU) admission. For statistical analysis, linear and binary logistic regression modeling were performed. A total of 153 patients with an average age of 88.5 (range 85 to 99) met the inclusion criteria. Our patients were mostly female (68.6%) and moderately comorbid according to a Charlson Comorbidity Index (CCI) of 2.9. 58.8% had diagnosed osteoporosis. Fracture morphologies represented as "Osteoporotic Fracture" (OF) classification types were of central importance for undergoing operative treatment (OP) (p < 0.001), necessity for intensive care (p = 0.023), LOS (p = 0.014), and mortality (p = 0.018). 38.6% had OP. We recorded a complication rate of 59.5%, which highly influenced (p < 0.001) both primary outcome parameters. Overall, patients stayed 14.6 days with a mortality of 11.1%. VFs are a severe event in oldest-old patients with a crucial risk of poor medical outcomes during hospitalization. The fracture morphologies are of central importance. However, little is known about the hospital stay of oldest-old inpatients with VFs. Considering an aging population, further investigations would be recommended.

Safety and efficacy of transurethral holmium laser enucleation of the prostate versus bipolar transurethral resection of the prostate in the treatment of benign prostatic hyperplasia: a prospective randomized controlled trial.

To evaluate the safety and efficacy of transurethral holmium laser enucleation of the prostate (HoLEP) compared to bipolar transurethral resection of the prostate (bTUR-P) in the treatment of benign prostatic hyperplasia (BPH). A total of 220 BPH patients hospitalized from January 2022 to September 2023 were included in this study. These patients were randomly assigned to HoLEP and bTUR-P groups, with 110 participants in each group. We collected preoperative general information, perioperative data, complications, and postoperative follow-up indicators from both groups of patients. The baseline characteristics of patients in both groups were similar, with no statistical significance (P > 0.05). Compared to the bTUR-P group, the HoLEP group exhibited significantly less intraoperative bleeding (P < 0.001), shorter bladder irrigation time (P = 0.002), shorter catheter retention time (P < 0.001), and reduced postoperative hospitalization (P = 0.002). Additionally, the pain score during urination after catheter removal was significantly lower in the HoLEP group (P < 0.001). Postoperative complications occurred in both groups; however, they were less frequent in the HoLEP group (4 cases), primarily consisting of urinary retention and postoperative bleeding. The bTUR-P group experienced more complications (9 cases). Significant reductions in postoperative residual urine volume (RUV) were observed in both groups (P < 0.001). Both groups also showed significant improvements in Quality of Life (QoL) scores and International Prostate Symptom Scores (IPSS), with the HoLEP group demonstrating a more significant decrease in IPSS (P < 0.001). After comprehensive evaluation, HoLEP was superior to bTUR-P in terms of safety and efficacy. Therefore, HoLEP may be a preferable choice for the treatment of BPH.

Propensity-Score Matching Analysis for Laser Hemorrhoidoplasty Versus Circumferential Stapler Hemorrhoidectomy: One-Year Outcomes.

Laser hemorrhoidectomy (LHP) is a minimally invasive procedure with less pain, short operative time and length of stay, and a low recurrent rate. This study aimed to analyze the surgical outcomes of the circumferential stapler hemorrhoidectomy (CSH, Longo operation) by propensity score-matching analysis, including perioperative outcomes and quality of life. Between March 2022 and March 2023, 216 patients underwent CSH and 198 LHP in Binh Dan Hospital, Ho Chi Minh City, Vietnam. Potential confounding factors for operative outcomes were adjusted by propensity score-matching analysis. The gender, age, Goligher classification, symptoms, Hemorrhoidal Disease Symptom Score (HDSS), and the number of hemorrhoidal columns were matching variables. After 1:1 propensity score-matching, 115 patients from each group were evaluated for perioperative outcomes and compared for a prospective study. There was no difference in potential preoperative confounders such as gender, hemorrhoid classification, symptoms, and HDSS between the two groups after propensity score-matching. However, there was a difference in age (52 in the Longo group and 43 in the LHP group) and the number of columns (the LHP group had more). Postoperative outcomes such as operative time, blood loss, general complications, and postoperative interventions were less in the LHP group. However, Visual Analog Scale (VAS) (4 vs. 4), length of stay (1 day vs. 1 day), quality of life (both groups improved quality of life after the procedure), and recurrence rate (2 in the Longo group vs. 0 in the LHP group, p=0.5) had no difference between the two groups. Propensity-score matching analysis showed that the LHP procedure was superior to the Longo operation (CSH) in operative time, blood loss, general complications, and postoperative intervention. Other outcomes such as VAS, length of stay, quality of life, and recurrence rate have no difference.

An integrated approach to the treatment of a patient with chronic tonsillitis. Clinical case

Chronic tonsillitis (CT) is a common infectious-allergic disease leading to severe general somatic complications, including rheumatic damage of joints and heart, kidney disease. Currently in Russia there is an increase in the number of patients with CT. Therapy for CT in outpatient practice is often limited to only washing the lacunae of the palatine tonsils, without the use of local drugs. We observed a 35-year-old patient with a diagnosis of chronic tonsillitis and a history of the disease of more than 1.5 years. A combined method of therapy was chosen, including treatment with the Tonsillor apparatus using low-frequency ultrasound therapy and local use of Viroxinol for irrigation of the tonsils and mucous membrane. As a result of the complex treatment, pronounced positive dynamics and a decrease in the clinical symptoms of CT were achieved.

Clinical characteristics and management of adipsic arginine vasopressin deficiency in children and adolescents with sellar germ cell tumors.

Adipsic arginine vasopressin deficiency(aAVP-D) is a rare, high-risk syndrome, particularly difficult to recognize and manage in children and adolescents. This investigation examined the clinical features and management of aAVP-D in children and adolescents with sellar germ cell tumors (GCTs). A retrospective survey was performed on 260 patients with sellar GCTs, categorized into aAVP-D and non-aAVP-D groups based on thirst presence. General characteristics, hypothalamic syndrome, pituitary function, metabolic indicators, and complications were compared. Biochemical indicator changes in the aAVP-D group were analyzed after systematic management, and receiver operating characteristic (ROC) curve analysis established the optimum serum sodium cut-off for predicting the aAVP-D. 25 patients (9.6%) developed aAVP-D. The aAVP-D group had larger tumors with hypothalamic involvement and more surgical resections. They also demonstrated more hypothalamic syndrome, central adrenal insufficiency, central hypogonadism, and insulin-like growth factor-1 levels below norms. Furthermore, aAVP-D patients exhibited significantly higher rates of hypernatremia (100% vs 20.9%, p < 0.001), hyperuricemia (60.0% vs 23.4%, p < 0.001), renal impairment (32.0% vs 1.7%, p < 0.001), and venous thrombosis (4.0% vs 0%, p = 0.002). Following systematic management, aAVP-D patients experienced significant reductions in serum sodium, uric acid, and creatinine levels, although these remained higher than in the non-aAVP-D group. ROC analysis indicated that a serum sodium level above 149.5mmol/L predicted aAVP-D. Conclusion Patients with aAVP-D had more tumor involvement in the hypothalamic region, surgical resections, hypothalamic syndrome, hypopituitarism, and complications. Serum sodium levels above 149.5mmol/L necessitated heightened vigilance for aAVP-D. Early identification and systematic management reduced complications, though clinical management remained challenging. What is Known •Adipsic arginine vasopressin deficiency (aAVP-D) is a rare and high-risk syndrome that is difficult to recognize and manage. •There are few reports on aAVP-D, most of which focus on adult patients. •The characteristics and management of aAVP-D in children and adolescents remain unclear. What is New •Children and adolescents with aAVP-D experienced higher rates of hypothalamic region tumor involvement, surgical resections, hypothalamic syndrome, hypopituitarism, and associated complications. •Serum sodium levels above 149.5mmol/L necessitated heightened vigilance for aAVP-D. •Early recognition and structured management of ADI lowered the risk of complications.

Evaluating the Efficacy and Complications of the Scapular Osseous Free Flap for Head and Neck Reconstruction: Results from a Population-based Cohort

IntroductionThe scapular osseous free flap (SOFF) is being increasingly used for complex head and neck reconstructions. This study examined the surgical outcomes, focusing on post-operative complications and sequelae in patients who underwent SOFF for maxillary and mandibular reconstructions. Material and MethodsThis retrospective, observational, population-based study included patients who underwent SOFF reconstruction at a tertiary referral centre, the Department of Otorhinolaryngology-Head and Neck Surgery, Skåne University Hospital, Sweden, from November 2016 to March 2023. All patients were followed-up for at least six months after surgery. ResultsForty-two of the 44 consecutive patients (60 % men) consented to the study and were evaluated with a median follow-up time of 49 months (range 8–85 months). The study divided the patients into two groups; maxillary (n = 29) and mandibular (n = 13) reconstructions. The World Health Organisation performance status and the Charlson comorbidity index were lower in the maxillary group (p = 0.025 and p = 0.011, respectively). The maxillary group experienced high complication rates including six total flap failures and nine oronasal fistulas. Conversely, the mandibular group had no flap failures but a similar rate of general post-operative complications were observed. Dental rehabilitation was more common in the maxillary group. ConclusionThe SOFF is an option for complex reconstructions of the maxilla but is associated with a relatively high rate of complications. Methods that can prevent or minimise sequelae, e.g., oronasal fistulas, in future patients are warranted. The SOFF is an excellent alternative for mandibular reconstructions.

The need for state-of-the-art orthopedic surgical technology in low- to middle income countries : The case of distraction epiphyseolysis for limb lengthening in children with fibular hemimelia in Uzbekistan.

Amongst low- to middle income countries (LMIC), outdated and poorly documented orthopedic interventions may pose patients at risk for complications, serious adverse events (SAE) and unsatisfactory results, contradicting the World Health Organization's (WHO) Safe Surgery mandates. Use cases of conditions managed inadequately in LMIC environments are necessary to increase awareness of stakeholders and overcome deficiencies in collaboration with high-income countries (HIC). Methodological and clinical experts from the BG Kliniken and the Charité, Berlin, Germany, were invited to investigate established processes for musculoskeletal disorders and injuries in Tashkent, Uzbekistan. Congenital lower leg discrepancy due to fibular hemimelia was recognized as an illustrative example to prove the effectiveness of local treatment guidelines, still relying on distraction epiphyseolysis (chondrodiatasis) via an Ilizarov frame. Routine data from hospital records, images and outpatient follow-up examinations were compared to estimates from a review of studies of limb-lengthening by other techniques. Data from 16 of 49 immature patients (10 males, 6 females, mean age at surgery, 4.2 ± 2.3 years) undergoing chondrodiatasis between 2017 and 2021 showed a mean limb elongation of 2.4 (95% confidence interval [CI], 1.9 to 2.9) cm after a median follow-up of 29 (range, 24 to 36) months. While no complications or SAE were noted, findings are compatible with a risk of 21% under an upper 97.5% confidence limit for null events. No reproducible classification of hemimelia, surgical or general complications, assessment of functional outcomes or health-related quality of life were available. The pooled average length gain from 21 studies on different other interventions with osteotomy enrolling 458 limbs was 5.1 (95% CI, 5.0 to 5.3) cm. Limb lengthening for hereditary fibular hemimelia in Uzbekistan revealed rather obsolete surgical algorithms, inadequate documentation, and unreliable outcome assessment. Resource limitations notwithstanding, knowledge transfer, implementation of current procedures and hardware, and international collaboration is vital to improve quality of care in this scenario and for the benefit of LMIC in general.

DRG payment for major pancreatic surgery: analysis of resource consumption and suggestions from a tertiary hospital in China.

To investigate the cost homogeneity within the Diagnosis-Related Group (DRG) "major operation of pancreas and liver, with general complications or comorbidities" (HB13), its cost-influencing factors, and to propose suggestions for better grouping efficacy. Medical and insurance settlement data of inpatients covered by the DRG payment system at the author's institution were collected from March 15, 2022 to December 31, 2023. The cost homogeneity of group HB13 was assessed using the coefficient of variation (CV). Clinical factors that may have an impact on hospitalization cost for patients undergoing pancreatic surgery were identified through a semi-structured interview administered to the pancreatic surgeons in author's department, their significance was analyzed using multiple linear regression, along with their impact on the cost of different service categories. A proposal to subdivide HB13 was made and evaluated by CV and t-test. The CV of the HB13 group was 0.4. Robotic-assisted surgery and pancreaticoduodenectomy were two independent factors that significantly affected the total cost. Patients undergoing robotic-assisted surgery have an average increase of 41,873 CNY in total cost, primarily derived from operation fee. Patients undergoing pancreaticoduodenectomy have an average increase of 37,487 CNY in total cost, with significant increases across all service categories. HB13 was subdivided based on whether pancreaticoduodenectomy was performed. The newly formed groups exhibited lower CVs than the original HB13. The cost homogeneity of HB13 was lower than that of other DRG groups in author's department. It is recommended to introduce a supplementary payment for patients requiring robotic-assisted surgery, to guarantee their access to this advanced technology. It is recommended to establish a new group with higher payment standard for patients undergoing pancreaticoduodenectomy. A tiered CV criterion for the evaluation of grouping efficacy is recommended to increase intra-group homogeneity, facilitating a better allocation of health insurance funds, and the prevention of unintended negative outcomes such as service cuts and cherry-picking.

Comparative efficacy of unilateral biportal and percutaneous endoscopic techniques in unilateral laminectomy for bilateral decompression (ULBD) for lumbar spinal stenosis

BackgroundUnilateral laminotomy for bilateral decompression (ULBD) has yielded positive results in the treatment of lumbar spinal stenosis (LSS). Unilateral biportal ULBD (UB-ULBD) and percutaneous endoscopic ULBD (PE-ULBD) are gaining popularity because of the progress that has been made in minimally invasive surgery (MIS). The objective of this study was to evaluate and compare the radiographic and clinical results of UB-ULBD and PE-ULBD.MethodsThis study retrospectively enrolled patients who underwent ULBD surgery for LSS. The patients were categorized into two groups on the basis of the surgical method: the UB-ULBD group and the PE-ULBD group. Data on the general demographic data, surgical details, clinical efficacy, radiography and complications were compared between the two groups were compared. The minimum follow-up duration was 12 months.ResultsA total of 113 LSS patients who had undergone ULBD at our institution were included, of whom 61 patients underwent UB-ULBD surgery and 52 underwent PE-ULBD surgery. The UB-ULBD group had a significantly shorter operation time (P < 0.05). The facet was significantly better preserved in the UB-ULBD group than in the PE-ULBD group, and the angle of ipsilateral facet joint resection in the UE-ULBD group was significantly smaller (P < 0.05). The ODI score, VAS score and modified Macnab criteria improved postoperatively in both groups. The UB-ULBD group had a 95.08% rate of excellent or good patient outcomes, whereas the PE-ULBD group had a 92.30% rate.ConclusionBoth UB-ULBD and PE-ULBD can provide favourable clinical outcomes when used to treat LSS. UB-ULBD is beneficial because of its shorter operation time, smaller angle of ipsilateral facet joint resection and better facet preservation, making it a viable and safe option for treating LSS while ensuring spinal stability.

Surgical or non-operative treatment of acute Achilles tendon rupture : What does the current literature say?

The Achilles tendon is the strongest tendon in humans and is frequently injured, especially in the physically active young to middle-aged population. An increasing frequency of Achilles tendon ruptures (ATR) has been reported in several studies. However, there is no international consensus regarding possible non-operative (N-OP) or operative (surgical) treatment (OP). The aim of this article is to semi-quantitatively compare both treatment options for ATR by analyzing the results reported in the literature. For this purpose, relevant categories were identified, and the literature was then evaluated in aPubMed analysis. Tenmeta-analyses and twocost analyses were included. The data was extracted according to the categories and evaluated comparatively. OP and N‑OP for acute ATR can lead to equally good restitution of clinical function if early functional rehabilitation is applied. The lower re-rupture rate is an advantage of OP, whereas the lower general complications speak in favor of N‑OP. The minimally invasive or percutaneous surgical technique (M-OP) appears to be advantageous over the open surgical technique (O-OP), although studies show an increased rate of lesions of the sural nerve. There is no consensus regarding the superiority of OP or N‑OP for acute ATR, as several studies conducted since the introduction of early mobilization protocols have shown similar results for these two interventions. Results and complications of M‑OP and O‑OP are also comparable. Considering the available data on the various surgical procedures, the authors prefer the M‑OP technique with adequate sural nerve protection for repair of acute ATR, combined with an early mobilization protocol.

Postoperative recovery after suspension suture placement at the site of esophagojejunal anastomosis after total gastrectomy: Comparison of two surgical techniques.

Despite improvements, survival rates for gastric cancer remain low, even in developed countries, confirming the role of primary and secondary prevention. This study aims to demonstrate the role of additional suspension sutures on the esophagojejunal anastomosis (EJA) to strengthen the anastomosis, i.e., relieve the mechanical suture. A retrospective cohort study was conducted from 2011 to 2022 at the Clinic for Surgery, University Clinical Center Tuzla, Bosnia and Herzegovina. The experimental group consisted of patients placed with a suspension suture at the esophagojejunal anastomosis (EJA) site after total gastrectomy. The control group was patients without a suspension suture. The clinical and laboratory parameters available from the medical history were analyzed, X-ray passage, surgical complications, non-surgical complications, the length of hospitalization, the postoperative course, time of onset of postoperative complications, postoperative radiological follow-up and endoscopic postoperative follow-up were then analyzed. A total of 212 patients were included in the study: 87 in the experimental group with suspension sutures on the EJA and 125 in the control group without suspension sutures on the EJA. The two cohorts did not differ in other clinicopathologic parameters except perineural invasion, which was more prevalent in the control group. Patients in both groups were anemic and elevated values of C reactive protein (CRP) and decreased levels of proteins, albumin and globulin, with no significant difference between the two groups. The most common general complication was pleural effusion (28%), followed by pneumonia (∼22%). The most common complication in the experimental group was an intraabdominal abscess, while in the control group, it was a surgical wound infection. Our study did not show a statistically significant difference between the two analyzed EJA techniques created with a circular stapler, when it comes to postoperative course and outcome in patients with gastric cancer.

Does the use of topical vancomycin during primary hip or knee arthroplasty protect from infections?

BackgroundInfection is one of the main complications of hip and knee arthroplasties. Topical application vancomycin to prevent postoperative infections is efficient in spine surgery, and is spreading in prosthetic surgery. However, its clinical relevance and safety are still under debate. Thus, we conducted the present study to (1) assess whether topical vancomycin reduces peri-prosthetic infection rate, and (2) investigate its influence on surgical wound complications. HypothesisOur hypothesis was that topical administration of diluted vancomycin during arthroplasty would reduce infection rate within the first postoperative year. Material and methodsIn total, 1900 hip and knee arthroplasties were performed between 2014 and 2021 in a single hospital. From July 2018 and December 2021, 910 prostheses were implanted with intra-articular instillation of vancomycin and tranexamic acid. From November 2014 to June 2018, 990 prostheses were set up without vancomycin. During a follow-up of minimum 12 months, we reported periprosthetic infections occurring during the first postoperative year, as well as vancomycin-induced general or cutaneous complications. ResultsWe observed periprosthetic infections in 9/990 cases (0.91%) of the control group and 10/910 cases (1.1%) of the vancomycin group (p = 0.82). In parallel, we observed wound complications (erythema, seroma, hematoma, dehiscence and delay in wound healing) in 19/990 (1.9%) and 10/910 cases (1.1%) of the control and vancomycin group, respectively (p = 0.19). There were no general complications resulting from the application of vancomycin. DiscussionTopical diluted vancomycin does not reduce periprosthetic infection risk, and has no effect on the occurrence of surgery wound complications. Considering the present findings, the use of vancomycin cannot be recommended in current practice to prevent infections following hip and knee arthroplasties. Finally, its use does not induce any specific complications, whether local (cicatrisation) or general (related to ototoxicity or nephrotoxicity). Level of evidenceIII; case control study.

Acute Vascular Complications of VA-ECMO in COVID-19 Patients. Does COVID-19 Affect the Outcome?

Extracorporeal membrane oxygenation (ECMO) through the femoral artery and vein can lead to significant vascular complications. We retrospectively studied the acute vascular complications of Veno-Arterial Extracorporeal Membrane Oxygenation (VA-ECMO) in COVID-19 patients compared to non-COVID patients during the period from January 2020 to July 2023. Seventy-eight patients underwent VA-ECMO for various indications from January 2020 to July 2023. The studied patients had a mean age of 59.6 ± 6.9 years for non-COVID patients (38 patients), and 62.2 ± 7.6years for COVID patients (40 patients), with a P = 0.268. In non-COVID patients, The baseline characteristics were similar in both groups. The primary indications for ECMO were cardiac diseases, followed by respiratory failure (78.9% vs 10.5%). Conversely, in COVID patients, respiratory failure due to COVID-19 infection was the main indication (45% vs 40%). The overall incidence of general complications, including cerebrovascular stroke, acute kidney injury, intracardiac thrombi, and wound infection, was comparable in both groups (31.6% vs 45%). The overall incidence of vascular complications in both groups was 33.3%. Ipsilateral acute lower limb ischemia occurred in 5.3% vs 10% of non-COVID and COVID patients, respectively. Thrombosis of the distal perfusion catheter (DPC) occurred in 10.5% vs 15%, respectively. During the COVID-19 pandemic, an increasing number of patients required VA-ECMO due to associated respiratory failure. Patients undergoing VA-ECMO are at high risk of developing various vascular complications. COVID-19 significantly increases the risk of acute limb ischemia and distal perfusion catheter thrombosis in both upper and lower limbs. However, other VA-ECMO-related vascular complications are comparable between COVID-19 and non-COVID patients.

Anesthetic management and anesthesia-related complications in dogs with a dilated cardiomyopathy phenotype: a retrospective study of 30 dogs (2010-2024).

To describe perioperative anesthetic management in canines with a dilated cardiomyopathy (DCM) phenotype and to compare the frequency of general anesthesia-related complications with a control group of dogs without heart disease. 30 dogs with DCM phenotype (cases) and 30 dogs without heart disease (controls). Dogs presented to a teaching hospital between 2010 and 2024 that were diagnosed with a DCM phenotype via echocardiography were included in this study. Controls were dogs that presented during the same time period and were matched with cases based on their age, breed, and type of procedure; however, no standardization of treatment between the groups was performed. Medical records were reviewed to evaluate the occurrence of anesthetic complications. Of dogs with a DCM phenotype, 2 had overt DCM, 22 had occult DCM, and 6 had equivocal DCM. Dogs with DCM exhibited a lower likelihood of being premedicated with dexmedetomidine or induced with propofol. Conversely, DCM dogs were more likely to be induced with etomidate or midazolam compared to their counterparts without DCM. Dogs with DCM demonstrated an increased likelihood of experiencing cardiac arrhythmias during anesthesia, received comparatively lower volumes of IV fluids, and were more likely to be administered dobutamine during anesthesia. No significant differences were identified in terms of postanesthesia complications or survival rates to discharge. Dogs with a DCM phenotype, primarily characterized by asymptomatic presentation, demonstrated comparable perioperative outcomes under general anesthesia when compared to matched controls, though the lack of standardization in anesthetic management limits definitive conclusions.

Modified buried vertical mattress suture technique for excisional suturing of benign parotid tumors: A retrospective study.

The purpose of this retrospective patient chart review was to analyze the clinical data of 52 patients with benign parotid tumors who underwent modified buried vertical mattress sutures and to assess the postoperative complication rate and patient scarring. A total of 52 patients with benign parotid tumors underwent total parotidectomy and modified buried vertical mattress suture. Variables included general characteristics (age, gender, tumor diameter, and pathologic type), surgical indicators (suture time, wound healing time, operative time, hospital stay, bleeding volume, and drainage volume), complication rates, and Sunnybrook facial neurological function score, visual scar scale (VSS) score and patient and observer scar assessment scale (POSAS) score. Most tumors were less than 3 cm in diameter, with pleomorphic adenomas being the most common. Suture time was 14.83 ± 1.61 min, operative time was 58.90 ± 15.76 min and hospital stay were 5.12 ± 0.96 days. Postoperatively, salivary fistulae developed in one patient, Frey's syndrome in two patients, temporary facial paralysis in six patients and temporary numbness in the incision area in six patients. At 6 months postoperatively, 86.5% of patients had a Sunnybrook score of more than 80, and VSS scores and POSAS scores were between one and two. The postoperative complication rate was 30.8%, and the scarring in the facial incision area was mild and close to normal skin at 3 years postoperatively.
