Higher Risk Of Postoperative Complications Research Articles

Does a delay of surgery due to a multidisciplinary screening process result in neuromuscular scoliosis curve progression in complex Cerebral Palsy?

While surgical intervention of scoliosis in cerebral palsy (CP) patients has shown notable improvements in quality of life, the high risk of post-operative complications in CP patients necessitates careful preoperative optimization. A preoperative multidisciplinary (Multi-D) pathway at our tertiary pediatric hospital in effect since 2014 led to a significant reduction in mortality at one year. However, such a strategy delays surgery, potentially increasing the risk of curve progression. This study aims to elucidate the impact of the Multi-D screening process on curve progression in neuromuscular scoliosis among complex CP patients. A retrospective review of all CP patients with scoliosis at a tertiary care center from 2012 to 2020 was conducted. This assessment focused on the progression of the major Cobb angle from the time of the indications conference to surgery of patients who went through Multi-D screening. Patient demographics and perioperative variables were obtained from the electronic medical record (EPIC, Systems Verona, WI). After exclusion criteria were met, there were 85 patients who went through Multi-D, 78 of whom had surgery, and seven who did not. Surgery was delayed an average of 202 days for Multi-D optimization. We found a trend in increasing Cobb angle over time, but this correlation did not reach statistical significance (p = 0.079). 45 Multi-D surgery participants had a decrease or no change in Cobb angle and had surgery an average of 5.6 months after indications. 33 Multi-D surgery participants had an increase in Cobb angle and had surgery an average of 8.5 months after indications. Cobb angle progressed an average of 13.4° in the increased group, and - 0.4° in the decrease or no change group. There were no associations with change in Cobb angle and GMFCS, starting major curve angle, number of referrals, or intrathecal baclofen pump use according to this analysis. Multi-D optimization resulted in an average delay in surgery of 6.7 months. Patients that did not have a change in Cobb angle had surgery within 5.6 months vs. patients that had an increase in Cobb angle had surgery on average 8.5 months after indicated for surgery, with an average increase of Cobb angle of 13.4°. Level III, retrospective comparative study.

Perioperative Considerations for Hip Arthroplasty in Patients with Rheumatoid Arthritis.

Due to its distinct features, rheumatoid arthritis (RA), an inflammatory autoimmune disorder, poses challenges in planning for surgical interventions. This review includes available evidence regarding perioperative considerations in management of RA patients, with a focus on hip surgery. RA can affect multiple joints, with development of extra-articular manifestations; therefore, preoperatively, comprehensive medical assessments, including cardiovascular or pulmonary evaluation must be considered in addition to surgical considerations. Modification of medications capable of controlling RA-related disease activity is critical, and requires collaboration with rheumatologists. Surgical considerations include the choice of surgical approach, implant selection, and problems related to weakened soft tissues, fragile bone density, and bony deformity such as protrusio acetabuli. Careful monitoring and more active rehabilitation are recommended for RA patients due to higher risk of postoperative complications. For achievement of optimal outcomes, use of a multidisciplinary perioperative approach is required for patients with RA.

Frailty as a predictor of mortality and morbidity after cholecystectomy: A systematic review and meta-analysis of cohort studies.

Although cholecystectomy is a common surgery, it carries higher risks of postoperative complications and mortality for older adults. Age alone is not a reliable predictor of postoperative outcomes, whereas frailty may provide a more accurate assessment of a patient's health and functional status. Frailty, characterized by physical deterioration and reduced resilience, has been shown to predict mortality, prolonged recovery, and morbidity after various surgeries, including cholecystectomy. Thus, incorporating frailty evaluations into preoperative assessments can improve patient outcomes by individualizing treatment strategies. This systematic review and meta-analysis aims to evaluate how well frailty predicts postoperative outcomes following cholecystectomy. In accordance with PRISMA guidelines, we searched PubMed, Embase, and Web of Science on August 14th, 2024, without restrictions on publication year or language. The quality of the studies was assessed using the Newcastle-Ottawa scale, and meta-analysis was conducted using odds ratios with 95% confidence intervals as the effect size, employing a random-effects model. Nine cohort studies comprising a total of 128,421 participants were included. The pooled results showed significantly higher odds of short-term mortality (OR: 5.54, 95% CI: 1.65-18.60, p = 0.006), postoperative morbidity (OR: 2.65, 95% CI: 1.51-4.64, p = 0.001), major morbidity (OR: 3.61, 95% CI: 1.52-8.59), and respiratory failure (OR: 3.85, 95% CI: 1.08-13.79) among frail patients. Additionally, frail patients had longer hospital stays (mean difference: 2.98 days, 95% CI: 1.91-4.04) and significantly higher odds of postoperative infection and sepsis. However, no association was evident with reoperation rates. This study highlights the value of utilizing frailty assessment tools in preoperative settings for predicting outcomes after cholecystectomy. These tools could improve decision-making in both emergency and elective situations, aiding in the choice between surgical and medical management, as well as between open and laparoscopic procedures tailored to each patient.

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.

Preoperative assessment of adults undergoing elective noncardiac surgery: Updated guidelines from the European Society of Anaesthesiology and Intensive Care.

When considering whether a patient is fit for surgery, a comprehensive patient assessment represents the first step for an anaesthetist to evaluate the risks associated with the procedure and the patient's underlying diseases, and to optimise (whenever possible) the perioperative surgical journey. These guidelines from the European Society of Anaesthesiology and Intensive Care Medicine (ESAIC) update previous guidelines to provide new evidence on existing and emerging topics that consider the different aspects of the patient's surgical path. A comprehensive literature review focused on organisation, clinical facets, optimisation and planning. The methodological quality of the studies included was evaluated using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) methodology. A Delphi process agreed on the wording of recommendations, and clinical practice statements (CPS) supported by minimal evidence. A draft version of the guidelines was published on the ESAIC website for 4 weeks, and the link was distributed to all ESAIC members, both individual and national, encompassing most European national anaesthesia societies. Feedback was gathered and incorporated into the guidelines accordingly. Following the finalisation of the draft, the Guidelines Committee and ESAIC Board officially approved the guidelines. In the first phase of the guidelines update, 17 668 titles were initially identified. After removing duplicates and restricting the search period from 1 January 2018 to 3 May 2023, the number of titles was reduced to 16 774, which were then screened, yielding 414 abstracts. Among these, 267 relevant abstracts were identified from which 204 appropriate titles were selected for a comprehensive GRADE analysis. Additionally, the study considered 4 reviews, 16 meta-analyses, 9 previously published guidelines, 58 prospective cohort studies and 83 retrospective studies. The guideline provides 55 evidence-based recommendations that were voted on by a Delphi process, reaching a solid consensus (>90% agreement). This update of the previous guidelines has covered new organisational and clinical aspects of the preoperative anaesthesia assessment to provide a more objective evaluation of patients with a high risk of postoperative complications requiring intensive care. Telemedicine and more predictive preoperative scores and biomarkers should guide the anaesthetist in selecting the appropriate preoperative blood tests, x-rays, and so forth for each patient, allowing the anaesthetist to assess the risks and suggest the most appropriate anaesthetic plan. Each patient should have a tailored assessment of their fitness to undergo procedures requiring the involvement of an anaesthetist. The anaesthetist's role is essential in this phase to obtain a broad vision of the patient's clinical conditions, to coordinate care and to help the patient reach an informed decision.

The association of obesity and in-hospital outcomes among patients undergoing ablation for atrial fibrillation: a propensity-score matched analysis

Abstract Background Obesity is a strong risk factor for atrial fibrillation (AF), and it can affect the prognosis of AF. However, the impact of obesity (BMI≥30 kg/m²) on postoperative complications after AF ablation has not been extensively studied. We aimed to evaluate the association of obesity with in-hospital outcomes among patients with AF who ablation procedures. Methods The study utilized the National Inpatient Sample (NIS) database 2016-2020. Patients were divided into obese and non-obese groups and matched with propensity score matching (1:1). This matching involved adjusting for baseline variables (including age, gender, primary expected payer, race, and median household income) and comorbidities (including diabetes, hypertension, hyperlipidemia, history of coronary artery bypass grafting (CABG), chronic kidney disease, hyperthyroidism, cardiomyopathy, prior stroke or transient ischemic attack, heart failure with preserved ejection fraction (HFpEF), heart failure with reduced ejection fraction (HFrEF), heart valve disease, coronary artery disease, chronic obstructive pulmonary disease (COPD), alcohol misuse, anemia, and smoking). Furthermore, a weighted analysis was conducted utilizing weights provided by the NIS, and multivariate logistic regression was used to calculate the odds ratio. Results A total of 29,440 patient with AF who underwent ablation were included. After propensity matching, (8,110 in obese and 8,110 in non-obese group) the baseline characteristics were not significantly different between the two groups. Obesity was independently associated with higher risk of pseudoaneurysm, hematoma, postoperative anemia, acute kidney injury, vasopressor need, mechanical ventilation, pulmonary embolism, and ischemic stroke in patients who underwent ablation for AF (Figure 1). In addition, obese group had significantly higher length of stay (median and IQR 2 [1-3] vs 2 [1-4]) and total charges (median and IQR: 131,248$ [95,303-197,784] vs 143,693$ [102,720-206728]) compared to non-obese group (p&amp;lt;0.001). However, in-hospital mortality was not significantly different between the two groups. Conclusion In patients who underwent AF ablation, obesity is associated with significantly higher risk of post-operative complications, as well as increased LOS and total hospital charges.

Social determinants of health and surgical outcomes of minimally invasive radical prostatectomy: a national population-based study.

Socioeconomic determinants of health (SDOH) are often unvalued during surgery risk stratification; hence, they might be a major source of disparity that can jeopardize outcomes related to urological surgery. The aim of our study is to evaluate the impact of SDOH on postoperative outcomes following minimally invasive radical prostatectomy (MIRP). Patients who underwent MIRP between 2011 and 2021 were retrospectively analyzed by using PearlDiver-Mariner, an all-payer insurance claims database. International Classification of Diseases diagnosis and procedure codes were used to identify patient's characteristics, postoperative complications and SDOH. Outcomes were compared using multivariable regression models. Overall, 100,035 patients (mean age = 63.24 ± 7.07) underwent MIRP. The 60-day postoperative complication rate was 18%. Approximately 6% of patients reported at least one SDOH at baseline. SDOH were associated with higher odds of 60-day postoperative complications (OR:1.24, 95% CI:1.15-1.34), including urinary tract infection (OR:1.32, 95% CI:1.20-1.45) and acute kidney injury (OR:1.31, 95% CI:1.00-1.39). Postoperative urethral stricture (OR:1.37, 95% CI:0.92-1.98) did not reach statistical significance at multivariable analysis. Patients with SDOH have a significantly higher risk of postoperative complications following MIRP, especially urinary infection and acute kidney injury. These findings are multifactorial and should prompt identifying measures that might help prevent this large-scale phenomenon.

Preoperative mortality risk evaluation in abdominal surgical emergencies: development and internal validation of the NDAR score from a national multicenter audit in Senegal

IntroductionAbdominal surgical emergencies have a high mortality rate. Effective management primarily relies on the early identification of patients at high risk of postoperative complications. The objective of our study was to determine the prognostic factors associated with poor outcomes from abdominal surgical emergencies in Senegal and to establish a predictive score for mortality for preoperative risk evaluation (NDAR (New Death Assessment Risk) score).MethodologyThis was a retrospective national cross-sectional study conducted over one year in 14 regions of Senegal. Adult patients (aged > 15 years) who presented with a traumatic or non-traumatic abdominal surgical emergency were included. The studied variables included clinical and paraclinical data. The variable of interest was death within 30 days of the surgery. Logistic regression was used to identify the factors independently associated with mortality. Risk factors identified after logistic regression analysis were weighted using odds ratio (OR) values rounded to the nearest whole number. The predictive capacity of the score was evaluated by analyzing the ROC (Receiver Operating Characteristic) curve based on the area under the curve (AUC).ResultsA total of 1114 patient records were included, with a mortality rate of 4.4%. Diagnoses were observed in patients included appendicitis in 39.8% of cases (n = 444), followed by peritonitis in 22.3% (n = 249), intestinal obstruction in 18.5% (n = 205), strangulated hernias in 10.5% (n = 117), and abdominal trauma in 6.1%. Logistic regression, established the following scores: age > 40 years (score 2), ASA status grade 2 or higher (score 1), presence of a positive QSIRS score (score 2), diagnosis of peritonitis (score 2), diagnosis of intestinal obstruction (score 1), and the presence of intestinal necrosis (score 3). The score is positive if the total is strictly greater than 5, indicating a 17.7% risk of mortality. This score had a high predictive capacity with an AUC of 0.7397.ConclusionThis study enabled the establishment of a score that allows for the early identification of at-risk patients, even in constrained resource settings, facilitating appropriate perioperative management and timely surgical intervention to reduce the risk of complications. This approach, focused on early recognition of high-risk patients, is crucial for improving clinical outcomes in abdominal surgical emergencies.

Inflammatory Signals Across the Spectrum: A Detailed Exploration of Acute Appendicitis Stages According to EAES 2015 Guidelines.

Background: In this retrospective study, we evaluate the diagnostic utility of C-reactive protein (CRP) and leucocyte count within the EAES 2015 guidelines for acute appendicitis (AA) in differentiating uncomplicated (UAA) from complicated AA (CAA). Methods: Conducted at a tertiary care center in Germany, the study included 285 patients over 18 years who were diagnosed with AA from January 2019 to December 2021. Patient data included demographics, inflammatory markers, and postoperative outcomes. Results: CRP levels (Md: 60.2 mg/dL vs. 10.5 mg/dL; p < 0.001) and leucocyte count (Md: 14.4 Gpt/L vs. 13.1 Gpt/L; p = 0.016) were higher in CAA. CRP had a medium diagnostic value for detecting CAA (AUC = 0.79), with a cutoff at 44.3 mg/L, making it more likely to develop CAA. Leucocyte count showed low predictive value for CAA (AUC = 0.59). CRP ≥ 44.3 mg/L was associated with a higher risk of postoperative complications (OR: 2.9; p = 0.002) and prolonged hospitalization (OR: 3.5; p < 0.001). Conclusions: CRP, within the context of the EAES classification, presents as a valuable diagnostic marker to distinguish CAA from UAA, with a higher risk of postoperative complications and hospitalization. Leucocyte count showed low diagnostic value for the identification of CAA.

Association of preoperative cognitive frailty with postoperative complications in older patients under general anesthesia: a prospective cohort study

BackgroundCognitive frailty (CF) is characterized by the coexistence of physical frailty and cognitive impairment, and it is associated with adverse health outcomes. Older adults are particularly vulnerable to CF due to factors such as age-related brain changes and the presence of comorbidities.ObjectiveTo investigate the effect of preoperative CF on postoperative complications in older patients.MethodsThis prospective cohort study was conducted among 253 patients aged 60–85 years, who underwent elective orthopedic and abdominal surgery (with a postoperative hospital stay of ≥ 3 days) at the Second Affiliated Hospital of Guangzhou University of Chinese Medicine from May 2023 to November 2023. CF was assessed using the Montreal Cognitive Assessment (MoCA) for the cognitive status and the Fried criteria for five frailty scales. Participants were split into four groups: Group A (neither frailty nor cognitive impairment), Group B (frailty without cognitive impairment), Group C (cognitive impairment without frailty), and Group D (cognitive frailty). The primary outcome was postoperative complications, while secondary outcomes included mobility disability, prolonged hospital stay (PLOS), re-operation and 90-day readmission.ResultsThe median age (interquartile range) of participants was 69 (65–73) years, of which 40.3% were male. The prevalence of CF was 17.8%. The incidence of postoperative complications was 18.2% in Group A, 50.0% in Group B, 37.4% in Group C, and 75.6% in Group D. Multivariate analysis revealed that, compared to the control group (without cognitive impairment or frailty), patients with CF had a significantly higher risk of postoperative complications (OR, 12.86; 95%CI, 4.23–39.08). “Patients with frailty without cognitive impairment” had an increased risk (OR, 6.53; 95%CI, 2.04–20.9), while “those with cognitive impairment without frailty” also showed a higher risk (OR, 3.46; 95%CI, 1.57–7.64).ConclusionsCognitive frailty is significantly associated with an increased risk of postoperative adverse outcomes in older patients undergoing orthopedic and abdominal surgeries with general anesthesia. It indicates that clinicians should pay much attention to these older adults with CF.

Cannabis Use Disorder Associated With Increased Risk of Postoperative Complications After Hip or Knee Arthroplasties: A Meta-analysis of Observational Studies.

With the legalization of marijuana in the United States, the number of patients with cannabis use disorder (CUD) in the joint arthroplasty population has increased markedly. The primary purpose of this meta-analysis was to determine whether there were differences in clinical and economic outcomes after total joint arthroplasty (TJA) between patients with and without perioperative CUD. We searched PubMed, Embase, Scopus, and Web of Science databases up to July 2018 to identify all eligible studies investigating the association of CUD with postoperative outcomes in patients undergoing TJA. Postoperative outcomes assessed consisted of complications, readmission, length of stay (LOS), implant revision, and cost of care. For dichotomous outcomes, pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated using a random effects model. We identified 10 retrospective cohort studies with a total of 17,981,628 study participants. Patients with CUD had significantly higher odds of medical complications (OR 1.33 [95% CI 1.07 to 1.66], P = 0.01) and implant-related complications (OR 1.75 [95% CI: 1.64 to 1.88], P < 0.00001) than noncannabis users. Specifically, CUD was associated with significantly increased odds of cardiac complications (OR 1.95 [95% CI 1.50 to 2.54], P < 0.00001), cerebrovascular accidents (OR 2.06 [95% CI 1.66 to 2.57], P < 0.00001), postoperative infections (OR 1.68 [95% CI 1.34 to 2.10], P < 0.00001), periprosthetic fracture (OR 1.42 [95% CI 1.19 to 1.70], P < 0.0001), mechanical loosening (OR 1.54 [95% CI 1.42 to 1.66], P < 0.00001), and dislocation/instability (OR 1.88 [95% CI 1.32 to 2.68], P = 0.0005). Longer LOS and higher cost of care were also found in patients with CUD. This study strengthens the body of evidence that patients with CUD face higher risk of postoperative complications and greater financial burden after knee and hip arthroplasties. Physicians should inform patients about adverse outcomes and undertake appropriate risk adjustments before elective orthopaedic surgery. Level III.

Predictive value of prognostic nutritional index in patients undergoing gastrectomy for gastric cancer: A systematic review and meta-analysis.

The value of prognostic nutritional index (PNI) in gastrectomy remains controversial. This meta-analysis aimed to evaluate the predictive value of PNI in patients undergoing gastrectomy for malignancy. We retrieved studies from medical literature databases to analyze the endpoints of overall survival, cancer-specific survival, recurrence-free survival, and clinicopathologic features. The hazard ratio (HR) and 95% confidence interval (CI) were used to access the survival prognostic value of PNI in patients after gastrectomy. Odds ratio and mean difference were used to evaluate the relationship between the low PNI and clinicopathologic features. In total, we included 38 articles (39 trial comparisons) which contained 23,756 gastrectomy patients. The results showed that low PNI was associated with shorter overall survival (HR: 1.82, 95% CI 1.62-2.03), shorter cancer-specific survival (HR: 1.44, 95% CI 1.24-1.67), and shorter recurrence-free survival (HR: 2.52, 95% CI 1.41-4.47). Besides, patients with low PNI had a higher risk of postoperative complications compared with high PNI (HR: 1.65, 95% CI 1.30-2.09). And low PNI group was found to be related to older, lower BMI, larger tumor size, deeper tumor invasion, poorer differentiation, more advanced tumor stage, total gastrectomy, and the presence of lymph node metastasis, lymphatic invasion, and vessel invasion. PNI was significantly associated with survival and postoperative complications of gastric cancer patients undergoing gastrectomy. Therefore PNI has the potential to be a prognostic predictor for gastrectomy.

Impacted third molar surgery in older patients—Is patient´s age really a risk factor for complications?

ObjectivesThe aim of this study was to analyze the influence of patients´ age on perioperative complications in impacted third molar surgery and how established risk factors are affected by age.Materials and methodsThe clinical findings, digital panoramic radiographs and perioperative data of 200 patients (554 impacted third molars) that had been subjected to tooth extraction, from July 2023 until July 2024, were analyzed. Perioperative complications (Inferior alveolar nerve (IAN) hypesthesia, oroantral communication (OAC), lingual nerve (LN) hypesthesia, postoperative bleeding, postoperative infection) as well as impaction patterns and risk factors (angulation type, bone coverage, depth- and risk scores) were analyzed by age (cut-off 30 years).ResultsThe population was divided into two groups by age (Group A = ≥ 30 years (n = 52) vs. Group B = < 30 years (n = 148)). Upper third molars showed significantly deeper bone coverage, higher depth scores, higher risk scores and different angulation types in patients aged < 30 years. Mandibular third molars showed significantly deeper bone coverage, higher depth scores, higher risk scores according and different angulation types in patients aged ≥ 30 years. However, IAN hypesthesia, LN hypesthesia, postoperative bleeding and postoperative infection did not show any significant differences regarding patients’ age.ConclusionThe current findings suggest that age (cut-off 30 years) does not statistically correlate with a higher risk for postoperative complications in impacted third molar surgery in contrast to recent publications.Clinical relevanceIn contrast to recent publications, the present study falsified a positive correlation between patients’ age and the occurrence of postoperative complications in impacted third molar surgery. Therefore, other risk factors should be investigated in order to minimize these procedure specific complications.

Timing of total joint arthroplasty post-COVID-19: an evaluation of the optimal window to minimize perioperative risks

BackgroundTotal hip arthroplasty (THA) and total knee arthroplasty (TKA) are commonly performed orthopedic procedures. This study aimed to evaluate the impact of COVID-19 status on postoperative complications and mortality in patients undergoing THA and TKA.MethodsA total of 110,186 underwent either THA or TKA. Patients were grouped based on their COVID-19 status, gathered from the National COVID-19 Cohort Collaborative (N3C) in the 12 weeks preceding surgery and compared for various variables, including age, sex, BMI, and Charlson Comorbidity Index (CCI) scores. COVID-19 status was defined as a positive test result that was closest to the date of surgery regardless of testing positive previously. Postoperative complications such as venous thromboembolism (VTE), sepsis, surgical site infection, bleeding, acute kidney injury (AKI), 30-day, and 1-year all-cause mortality were examined. To compare the variables, an odds ratio with a 95% confidence interval was calculated with a significant level set at P < 0.05. Logistic regression using R programming was utilized for these calculations.ResultsUnivariate analysis was performed and rates of VTE (1.02% vs. 3.35%), 30-day mortality (0.25% vs. less than 5%), and 1-year mortality (1.42% vs. 5.43%) were higher in the COVID-19-positive group for THA patients (P < 0.001). For TKA patients, only 30-day mortality was significantly higher in the COVID-19-positive group (P = 0.034). Multivariate logistic regression revealed that a positive COVID-19 diagnosis within two weeks of surgery and a CCI score > 3 were significant predictors of postoperative complications and mortality for both TKA and THA.ConclusionsPatients with a positive COVID-19 diagnosis within 12 weeks of THA or TKA carried a significantly higher risk for postoperative complications and mortality. In addition, a CCI score > 3 is also a significant risk factor. These findings emphasize the importance of vigilant preoperative screening and risk stratification in the era of COVID-19.

Elderly trochanteric fracture outcomes: Unveiling the risks of excessive postoperative sliding - A retrospective multicenter (TRON group) investigation

BackgroundIntramedullary nailing (IMN) for femoral trochanteric fractures (FTF) is the primary surgical intervention. Excessive lag screw sliding (ES) of the femoral neck screw sometimes occurs. This multicenter investigation sought to 1) determine the prevalence of ES, 2) evaluate the relationship between ES and postoperative complications, and 3) identify the factors of ES in elderly patients with FTF undergoing IMN. MethodsFrom 2016 to 2020, 1448 patients with FTF were treated using a short IMN across 11 institutions (TRON group). Upon applying exclusion criteria, 519 patients (127 men, 392 women; mean age, 84.4 years) were included. The postoperative sliding distance was measured immediately after surgery and at final follow-up. A sliding distance of ≥8 mm categorized patients as having ES. We identify the factors contributing to ES using the logistic regression analysis, with a p < 0.05 as statistical significance. ResultsES was observed in 116 patients (22.4 %). Patients with ES had a higher incidence of postoperative cut-out and peri-implant fracture. Logistic regression analysis showed that achieving optimal reduction in both AP and lateral views (odds ratio (OR) 0.48, p = 0.0012) and the use of a double screw system or twin screws with integrated locking mechanism significantly reduced the risk of ES (OR 0.27, 0.17; p = 0.0027, <0.001). ConclusionsThe incidence rate of ES was 22.4 %. ES was associated with a higher risk of postoperative complications. The surgeons should aim for optimal reduction and use a double screw or twin screws with an integrated interlocking mechanism as the implant of choice.

Multicenter analysis of the efficacy of early cholecystectomy and preoperative cholecystostomy for severe acute cholecystitis: a retrospective study of data from the multi-institutional database of the Hiroshima Surgical Study Group of Clinical Oncology

BackgroundSevere acute cholecystitis (AC) is a challenging disease because it comprises coexisting systemic infections that lead to vital organ dysfunction. This study evaluated the optimal surgical timing and efficacy of preoperative percutaneous cholecystostomy (PC) for patients with severe AC.MethodsData of 142 patients who underwent cholecystectomy for severe AC between 2011 and 2021 were retrospectively collected from the multi-institutional database of the Hiroshima Surgical Study Group of Clinical Oncology. Patients were divided into the early cholecystectomy (EC) group (within 72 h of symptom onset) and delayed cholecystectomy (DC) group. They were also subdivided into the upfront cholecystectomy group and preoperative PC before cholecystectomy group. The diagnosis and severity of AC were graded according to the Tokyo Guidelines 2018. Clinicopathological variables and outcomes were compared.ResultsNo significant differences in age, body mass index, American Society of Anesthesiologists (ASA) classification, and Charlson comorbidity index between the EC and DC groups were observed. Preoperative drainage was more commonly performed for the DC group than for the EC group. Local severe AC features were more commonly detected in the DC group than in the EC group. The postoperative outcomes of the EC and DC groups were comparable. Compared to the PC before cholecystectomy group, the upfront cholecystectomy group included more patients with ASA physical status ≥ 3 and more patients who used oral warfarin. Warfarin usage and cardiovascular dysfunction rates of the PC after cholecystectomy group were higher than those of the upfront cholecystectomy group. PC was associated with significantly less intraoperative bleeding and shorter hospital stays.ConclusionsPatients who can tolerate general anesthesia are good candidates for EC. Patients who use warfarin and those with cardiovascular dysfunction are considered to be at high risk for postoperative complications; therefore, to prevent AC recurrence during the waiting period, PC before cholecystectomy during the same admission is more appropriate than upfront cholecystectomy for these patients.

Non-Descemet stripping endothelial keratoplasty for bullous keratopathy in patients with atopic dermatitis: A long-term case report.

Patients with atopic dermatitis undergoing penetrating keratoplasty (PKP) face a high risk of postoperative complications. Endothelial keratoplasty may be a safer alternative for such patients, including those with abnormal anterior chamber anatomy. 3 male patients, aged 33 to 44, presented with blurred vision at Keio University Hospital. Bullous keratopathy was diagnosed through slit-lamp examination and specular microscopy. Two patients had well-controlled systemic atopic dermatitis, while 1 had blepharitis associated with atopic dermatitis. Two patients had peripheral anterior synechia, and 2 had undergone glaucoma surgery before keratoplasty. Non-Descemet stripping endothelial keratoplasty (nDSAEK) was performed by a single surgeon. The best-corrected visual acuity ranged from 0.7 to 1.5 logMAR before surgery and from 0.2 to 2.3 logMAR after surgery. One year post-surgery, the graft remained clear in 2 cases; however, in the case of repeated glaucoma surgeries after nDSAEK, the graft became edematous. Corneal endothelial cell density was 1586 and 1988 cells/mm² in 2 cases and undetectable in the failed case. The follow-up period ranged from 2.5 to 9 years. Despite the presence of peripheral anterior synechia or prior glaucoma surgery, some patients experienced a favorable long-term postoperative course following nDSAEK. This procedure may offer a safer alternative for treating patients with atopic dermatitis who have ocular complications that present a high risk for PKP.

COPD Patient's Outcomes following Total Knee Arthroplasty-An Analysis of the National Inpatients Sampling (2016-2020).

Total knee arthroplasty (TKA) is a common elective procedure aimed at improving patients' quality of life. Patients undergoing this procedure can have a wide variety of comorbidities, including chronic obstructive pulmonary disease (COPD). Several studies demonstrated a higher risk of postoperative complications for this patient population. In this study, we examined the mortality risk of this group of patients, as well as the length of stay (LOS) and general costs. This study is a retrospective, case-control study. Using the National Inpatients Sampling (NIS) database, we defined a cohort of adults who received their inpatient primary TKA between 1 January 2016 and 31 December 2020. Preoperative variables include age, sex, race, primary payer, hospital location, and hospital type. Outcomes examined in this study include overall patient mortality as a primary outcome. Secondary outcomes include total LOS (in days) and inpatient costs in the United States (in USD). A total of 2,835,499 patients who underwent TKA procedure in the United States were included. A total of 173,230 (6.1%) COPD patients were included in the COPD group. The mortality rate in the COPD group (0.1%) was more than three times higher than the control group (0.03%, p-value < 0.001). Patients in the COPD group had a longer in-hospital length of stay (2.76) compared to the control group (2.31, p-value < 0.001) and a higher treatment cost (average value of treatment per patient) (USD 69,386) compared to the control group (USD 64,446, p-value < 0.001). We also found higher mortality risk for patients older than 60 and patients of white ethnicity. COPD patients undergoing TKA have a higher mortality rate and this issue should be addressed in order to improve patient care and outcomes.

Open versus Minimally Invasive Partial Nephrectomy: Trends and Outcomes from a Wide National Population-Based Database.

Objectives: To investigate temporal trends and overall complication rates among open partial nephrectomy (OPN) and minimally invasive partial nephrectomy (MIPN), including the impact of social determinants of health (SDOH) on postoperative outcomes. Methods: Patients who underwent OPN or MIPN between 2011 and 2021 were retrospectively analyzed by using PearlDiver-Mariner, an all-payer insurance claims database. The International Classification of Diseases diagnosis and procedure codes were used to identify the type of surgical operation, patient's characteristics (age, sex, region, insurance plan), postoperative complications and SDOH, categorized in education, healthcare, environmental, social, and economic domains. Outcomes were compared using multivariable regression models. Results: Overall, 65,325 patients underwent OPN (n = 23,377) or MIPN (n = 41,948). OPN adoption declined over the study period, whereas that of MIPN increased from 24% to 34% (p = 0.001). The 60-day postoperative complication rate was 15% for the open and 9% for the minimally invasive approach. Approximately 16% and 11% of patients reported at least one SDOH at baseline for OPN and MIPN, respectively. SDOH were associated with higher odds of postoperative complications (OPN = OR: 1.11, 95% CI: 1.01-1.25; MIPN = OR: 1.31, 95% CI: 1.18-1.46). The open approach showed a significantly higher risk of postoperative complications (OR: 1.62, 95% CI: 1.54-1.70) compared to the minimally invasive one. Conclusions: Our findings confirm that MIPN is gradually replacing OPN, which carries a higher risk of complications. SDOH are significant predictors of postoperative complications following PN, regardless of the approach.

Alvimopan for postoperative ileus following abdominal surgery: a systematic review.

Postoperative ileus (POI) is a common complication following abdominal surgery, often leading to extended hospital stays and a higher risk of post-operative complications, leading to poorer patient outcomes. Alvimopan, a peripherally acting µ-opioid receptor antagonist, has been shown to aid in the recovery of normal bowel function after surgery. While its benefits are well-established in open abdominal surgeries, its efficacy in laparoscopic procedures had not been conclusively determined. However, recent clinical trials involving laparoscopic surgeries have since been conducted. This review aims to reassess the efficacy of Alvimopan by incorporating findings from these new studies, potentially providing further insight into its clinical benefits. A comprehensive search of PubMed, Google Scholar, EMBASE, and the Cochrane Library was conducted. Studies were included based on the PICO framework, focusing on Alvimopan's impact on postoperative gastrointestinal recovery. Primary outcomes were time to gastrointestinal function recovery (GI-3) and hospital stay duration. Ten studies met the inclusion criteria, with seven focusing on the use of Alvimopan in open abdominal surgeries and three in laparoscopic procedures. Collectively, these studies involved 18,822 patients undergoing various types of abdominal Administration of Alvimopan 6mg accelerated gastrointestinal function recovery by an average of 14h (Hazard ratio: 1.62, p = 0.002) and reduced hospital stays by 5.2h (Hazard ratio: 1.52, p = 0.04) compared to placebo. Similarly, Alvimopan 12mg reduced GI-3 recovery time by 13.5h (Hazard ratio: 1.58, p = 0.02) and hospital stay duration by 6.2h (Hazard ratio: 1.46, p = 0.018). Alvimopan shows promise in reducing POI and hospital stay durations following abdominal surgeries. The incorporation of the recent studies in laparoscopic abdominal procedures further supports these findings. Integrating Alvimopan into perioperative care protocols may enhance patient outcomes and help lower healthcare costs.
