RESUMO
Early-stage lung cancer patients are increasingly considered for preoperative systemic therapy. Older adults in particular are among the most vulnerable patients, with little known on how preoperative therapies affect the risk-benefit of surgery. We sought to summarize the current literature and elucidate existing evidence gaps on the effects of prehabilitation interventions relative to age-related functional impairments and the unique needs of older patients undergoing lung cancer surgery. A literature review was performed using PubMed and Google Scholar databases, of all scientific articles published through April 2022 which report on the effects of prehabilitation on patients undergoing lung cancer surgery. We extracted current prehabilitation protocols and their impact on physical functioning, resilience, and patient-reported outcomes of older patients. Emerging evidence suggests that prehabilitation may enhance functional capacity and minimize the untoward effects of surgery for patients following lung resection similar to, or potentially even better than, traditional postoperative rehabilitation. The impact of preoperative interventions on surgical risk due to frailty remains ill-defined. Most studies evaluating prehabilitation include older patients, but few studies report on activities of daily living, self-care, mobility activities, and psychological resilience in older individuals. Preliminary data suggest the feasibility of physical therapy and resilience interventions in older individuals concurrent with systemic therapy. Future research is needed to determine best prehabilitation strategies for older lung cancer patients aimed to optimize age-related impairments and minimize surgical risk.
RESUMO
PURPOSE: We aimed to identify preoperative risk factors for secondary spontaneous pneumothorax surgery. METHODS: The National Clinical Database of Japan, with six annual datasets from 2014 to 2019, was used. All patients who underwent surgery for secondary spontaneous pneumothorax were included, excluding those < 15 years old and those with incomplete data. The effects of preoperative risk factors were analyzed for operative mortality (mortality during hospitalization or within 30 days, regardless of hospitalization status), 30-day mortality, and postoperative respiratory morbidities. RESULTS: Of the 18,309 patients enrolled in the study, operative mortality, 30-day mortality, and postoperative respiratory morbidities were observed in 654 (3.6%), 343 (1.9%), and 2258 (12.3%) patients, respectively. Increasing age, male sex, body mass index < 18.5 or > 30, performance status > 2, emergent surgery, interstitial pneumonia, and diabetes in preoperative co-morbidity, tumors, and other diseases in underlying lung disease were significant risk factors for operative mortality. Those for 30-day mortality included autoimmune disease instead of male sex and diabetes, while those for postoperative respiratory morbidities included lymphangiomyomatosis instead of a body mass index > 30. CONCLUSION: We identified many preoperative risk factors for operative mortality, 30-day mortality, and postoperative respiratory morbidities in secondary spontaneous pneumothorax surgery. These findings will assist in selecting appropriate surgical candidates.
RESUMO
BACKGROUND: The conventional two-step process for surgical procedures - surgical followed by anaesthetic consultation - may not adequately address the needs of complex cases involving high-risk patients or procedures, leading to increased risks of adverse events. Although surgical team meetings (STM) and multidisciplinary team meetings (MDTM) were implemented many years ago, anaesthesia team meetings (ATM) have recently emerged as potential solutions to enhance perioperative management. PURPOSE: We aim to systematically review and summarize the existing literature that reflects the main theoretical approaches, practices, effects, and clinical relevance of preoperative team meetings - with specific consideration to preoperative ATM - in managing difficult cases. METHODS: We performed a narrative review of the literature (1980 - 2024) to identify studies focusing on the practice and the impact of preoperative meetings on patient outcomes, compliance with treatment plans, and teamwork quality. We provide here a qualitative synthesis of the findings. RESULTS: Fourteen studies were identified: 11 consider preoperative multidisciplinary team meeting (MDTM), 2 consider preoperative surgical team meeting (STM), and only one anaesthesia team meeting (ATM). CONCLUSIONS: There is currently not enough robust evidence that preoperative team meetings clearly improve hard patient's outcome parameters. And the place for ATM does not appear to have been studied to date. There is a need for well-designed studies to explore the impact of preoperative ATM on clinical practice improvement, quality of care, and patient outcomes.
RESUMO
Difficult laparoscopic cholecystectomy (LC) is defined by its surgical outcomes, including operative time, conversion to open surgery, bile duct and/or vascular injury. Difficult LC can be graded based on intraoperative findings. The main objective of this study is to apply and validate the reliability of their proposed risk score to predict the operative difficulty of an LC, based on their own validated intraoperative scale. Single-center prospective cohort study from 01/2020-12-2023. 367 patients > 18 years who underwent LC were included. The preoperative risk scale and intraoperative grading system were registered. Surgical outcomes were determined. Predictive accuracy was evaluated by the Receiver Operator Characteristic curve, sensitivity, specificity, positive, and negative predictive values, and Youden's Index (J). Patients' mean age was 44.1 ± 15.3 years. According to the risk score, 39.5% LC were "low" risk difficulty, 49.3% were "medium" risk, and 11.2% were "high" risk difficult LC. Based on the intraoperative grading system, 31.9% were difficult LC (Nassar grades 3-4) and 68.1% were easy LC (Nassar grades 1-2). There was a statistically significant correlation (0.428, p < 0.05) between the preoperative risk score and the intraoperative grading system. The AUC for the preoperative risk score scale and intraoperative difficult LC was 0.735 (95% CI 0.687-0.779) (J: 0.34). A preoperative risk score > 1.5 had an 83.7% sensitivity and a 50.8% specificity for intraoperative difficult LC. A predictive preoperative score for difficult LC and a routine collection of the intraoperative difficulty should be implemented to improve surgical outcomes and surgical planning.
RESUMO
Background: Under-represented minorities and those with noncommercial insurance have higher medical comorbidities and complications following elective total joint arthroplasty (TJA). In an effort to bridge this gap, our center implemented a preoperative optimization protocol for TJA in a Medicaid Clinic (Clinic). The purpose of this study is to assess the effectiveness of that protocol and highlight challenges associated with caring for this patient population. Methods: This retrospective analysis included 117 patients undergoing TJA between January 2015 and January 2020. In 2015, the protocol was implemented as a mandatory practice prior to TJA. A contemporary control cohort from the private office was also analyzed. Patient demographics, American Society of Anesthesiologists score, and postoperative complications were collected. Results: Within the clinic group, 52.5% (62) patients identified as Hispanic with 46.6% (55) Spanish-speaking as primary language, compared to 9.3% (11) and 8.5% (10) in the office group (P = .0001), respectively. Clinic group patients were significantly more likely to experience a complication compared to office patients (20 vs 7, respectively). There was no difference in complication or reoperation rate between clinic patients who underwent the optimization protocol and those who did not. Conclusions: The findings from this study highlight the demographic and comorbidities profile of an underserved population, and report on results of a quality improvement initiative among that population, which failed to improve postoperative outcomes. These results underscore the need for further study in this population to improve outcomes and health equity.
RESUMO
BACKGROUND: For patients with rectal cancer, the utilization of temporary ileostomy (TI) has proven effective in minimizing the occurrence of severe complications post-surgery, such as anastomotic leaks; however, some patients are unable to reverse in time or even develop a permanent stoma (PS). We aimed to determine the preoperative predictors associated with TS failure and develop and validate appropriate predictive models to improve patients' quality of life. METHODS: This research included 403 patients with rectal cancer who underwent temporary ileostomies between January 2017 and December 2021. All patients were randomly divided into either the developmental (70%) or validation (30%) group. The independent risk factors for PS were determined using univariate and multivariate logistic regression analyses. Subsequently, a nomogram was constructed, and the prediction probability was estimated by calculating the area under the curve (AUC) using receiver operating characteristic (ROC) analysis. A calibration plot was used to evaluate the nomogram calibration. RESULTS: Of the 403 enrolled patients, 282 were randomized into the developmental group, 121 into the validation group, and 58 (14.39%) had a PS. The development group consisted of 282 patients, of whom 39 (13.81%) had a PS. The validation group consisted of 121 patients, of whom, 19 (15.70%) had a PS; 37 related factors were analyzed in the study. Multivariate logistic regression analysis demonstrated significant associations between the occurrence of PS and various factors in this patient cohort, including tumor location (OR = 6.631, P = 0.005), tumor markers (OR = 2.309, P = 0.035), American Society of Anesthesiologists (ASA) score (OR = 4.784, P = 0.004), T4 stage (OR = 2.880, P = 0.036), lymph node metastasis (OR = 4.566, P = 0.001), and distant metastasis (OR = 4.478, P = 0.036). Furthermore, a preoperative nomogram was constructed based on these data and subsequently validated in an independent validation group. CONCLUSION: We identified six independent preoperative risk factors associated with PS following rectal cancer resection and developed a validated nomogram with an area under the ROC curve of 0.7758, which can assist surgeons in formulating better surgical options, such as colostomy, for patients at high risk of PS.

OBJECTIVES: To evaluate if ileo-psoas muscle size and visceral adipose tissue (VAT) can predict long-term survival after endovascular aneurysm repair (EVAR). METHODS: Patients who underwent EVAR between 2004 and 2012 in a single centre were included. Total psoas muscle area (TPA), abdominal VAT area, subcutaneous adipose tissue (SAT), and total adipose tissue were measured on the preoperative CT. Primary endpoint was all-cause mortality. Values are presented as median and interquartile range or absolute number and percentage. Cox regression analyses were performed to assess the associations with mortality. RESULTS: Two hundred and eighty-four patients could be included in the study. During a median follow-up of 8 (4-11) years, 223 (79.9%) patients died. Age (P ≤ .001), cardiovascular (P = .041), cerebrovascular (P = .009), renal diseases (P = .002), and chronic obstructive pulmonary disease (P ≤ .001) were independently associated with mortality. TPA was associated with mortality in a univariate (P = .040), but not in a multivariate regression model (P = .764). No significant association was found between mortality and TPA index (P = .103) or any of the adiposity measurements with the exception of SAT (P = .040). However, SAT area loss in a multivariate analysis (P = .875). CONCLUSIONS: Assessment of core muscle size and VAT did not contribute to improving the prediction of long-term survival after EVAR. ADVANCES IN KNOWLEDGE: The finding of this study contradicts the previously claimed utility of core muscle size and VAT in predicting long-term survival after EVAR.

PURPOSE: Accurate identification of lymph node (LN) metastases is pivotal for surgical planning of pancreatic neuroendocrine tumours (PanNETs); however, current imaging techniques have sub-optimal diagnostic sensitivity. Aim of this study is to investigate whether [68Ga]Ga-DOTATOC PET radiomics might improve the identification of LN metastases in patients with non-functioning PanNET (NF-PanNET) referred to surgical intervention. METHODS: Seventy-two patients who performed preoperative [68Ga]Ga-DOTATOC PET between December 2017 and March 2022 for NF-PanNET. [68Ga]Ga-DOTATOC PET qualitative assessment of LN metastases was measured using diagnostic balanced accuracy (bACC), sensitivity (SN), specificity (SP), positive and negative predictive values (PPV, NPV). SUVmax, SUVmean, Somatostatin receptor density (SRD), total lesion SRD (TLSRD) and IBSI-compliant radiomic features (RFs) were obtained from the primary tumours. To predict LN involvement, these parameters were engineered, selected and used to train different machine learning models. Models were validated using tenfold repeated cross-validation and control models were developed. Models' bACC, SN, SP, PPV and NPV were collected and compared (Kruskal-Wallis, Mann-Whitney). RESULTS: LN metastases were detected in 29/72 patients at histology. [68Ga]Ga-DOTATOC PET qualitative examination of LN involvement provided bACC = 60%, SN = 24%, SP = 95%, PPV = 78% and NPV = 65%. The best-performing radiomic model provided a bACC = 70%, SN = 77%, SP = 61%, PPV = 60% and NPV = 83% (outperforming the control model, p < 0.05*). CONCLUSION: In this study, [68Ga]Ga-DOTATOC PET radiomics allowed to increase diagnostic sensitivity in detecting LN metastases from 24 to 77% in NF-PanNET patients candidate to surgery. Especially in case of micrometastatic involvement, this approach might assist clinicians in a better patients' stratification.

Retrospective cohort study. To assess the utility of the LACE index for predicting death and readmission in patients with spinal infections (SI). SIs are severe conditions, and their incidence has increased in recent years. The LACE (Length of stay, Acuity of admission, Comorbidities, Emergency department visits) index quantifies the risk of mortality or unplanned readmission. It has not yet been validated for SIs. LACE indices were calculated for all adult patients who underwent surgery for spinal infection between 2012 and 2021. Data were collected from a single academic teaching hospital. Outcome measures included the LACE index, mortality, and readmission rate within 30 and 90 days. In total, 164 patients were analyzed. Mean age was 64.6 (± 15.1) years, 73 (45%) were female. Ten (6.1%) patients died within 30 days and 16 (9.8%) died within 90 days after discharge. Mean LACE indices were 13.4 (± 3.6) and 13.8 (± 3.0) for the deceased patients, compared to 11.0 (± 2.8) and 10.8 (± 2.8) for surviving patients (p = 0.01, p < 0.001), respectively. Thirty-seven (22.6%) patients were readmitted ≤ 30 days and 48 (29.3%) were readmitted ≤ 90 days. Readmitted patients had a significantly higher mean LACE index compared to non-readmitted patients (12.9 ± 2.1 vs. 10.6 ± 2.9, < 0.001 and 12.8 ± 2.3 vs. 10.4 ± 2.8, p < 0.001, respectively). ROC analysis for either death or readmission within 30 days estimated a cut-off LACE index of 12.0 points (area under the curve [AUC] 95% CI, 0.757 [0.681-0.833]) with a sensitivity of 70% and specificity of 69%. Patients with SI had high LACE indices that were associated with high mortality and readmission rates. The LACE index can be applied to this patient population to predict the risk of early death or unplanned readmission.

OBJECTIVE: Perioperative risk assessment and stratification before craniotomy is necessary to identify and optimize modifiable risk factors. Due to the high costs of diagnostic testing and concerns for delaying surgery, some have questioned whether and when surgery delays are warranted and supported by the current body of literature. The objective of this scoping review was to evaluate the available evidence on the prognostic value of preoperative risk assessment before anesthesia for elective craniotomy. METHODS: In this scoping review, we reviewed 156 papers that assess preoperative risk assessment before elective craniotomy, of which 27 papers were included in the final analysis. RESULTS: There is little high-quality evidence to suggest significant risk reduction when 4 common preexisting abnormalities are present: preoperative chronic aspirin therapy, cardiac arrhythmias, deep vein thrombosis, or hyperglycemia. CONCLUSIONS: The risk of delaying craniotomy should ultimately be weighed against the perceived risks associated the patient's comorbid conditions and should be considered on an individualized basis.

BACKGROUND: Postoperative complications remain a paramount concern for surgeons and healthcare practitioners. AIM: To present a comprehensive analysis of the Estimation of Physiologic Ability and Surgical Stress (E-PASS) scoring system's efficacy in predicting postoperative complications following abdominal surgery. METHODS: A systematic search of published studies was conducted, yielding 17 studies with pertinent data. Parameters such as preoperative risk score (PRS), surgical stress score (SSS), comprehensive risk score (CRS), postoperative complications, postoperative mortality, and other clinical data were collected for meta-analysis. Forest plots were employed for continuous and binary variables, with χ2 tests assessing heterogeneity (P value). RESULTS: Patients experiencing complications after abdominal surgery exhibited significantly higher E-PASS scores compared to those without complications [mean difference and 95% confidence interval (CI) of PRS: 0.10 (0.05-0.15); SSS: 0.04 (0.001-0.08); CRS: 0.19 (0.07-0.31)]. Following the exclusion of low-quality studies, results remained valid with no discernible heterogeneity. Subgroup analysis indicated that variations in sample size and age may contribute to heterogeneity in CRS analysis. Binary variable meta-analysis demonstrated a correlation between high CRS and increased postoperative complication rates [odds ratio (OR) (95%CI): 3.01 (1.83-4.95)], with a significant association observed between high CRS and postoperative mortality [OR (95%CI): 15.49 (3.75-64.01)]. CONCLUSION: In summary, postoperative complications in abdominal surgery, as assessed by the E-PASS scoring system, are consistently linked to elevated PRS, SSS, and CRS scores. High CRS scores emerge as risk factors for heightened morbidity and mortality. This study establishes the accuracy of the E-PASS scoring system in predicting postoperative morbidity and mortality in abdominal surgery, underscoring its potential for widespread adoption in effective risk assessment.
RESUMO
In silico simulations can be used to evaluate and optimize the safety, quality, efficacy and applicability of medical devices. Furthermore, in silico modeling is a powerful tool in therapy planning to optimally tailor treatment for each patient. For this purpose, a workflow to perform fast preoperative risk assessment of paravalvular leakage (PVL) after transcatheter aortic valve replacement (TAVR) is presented in this paper. To this end, a novel, efficient method is introduced to calculate the regurgitant volume in a simplified, but sufficiently accurate manner. A proof of concept of the method is obtained by comparison of the calculated results with results obtained from in vitro experiments. Furthermore, computational fluid dynamics (CFD) simulations are used to validate more complex stenosis scenarios. Comparing the simplified leakage model to CFD simulations reveals its potential for procedure planning and qualitative preoperative risk assessment of PVL. Finally, a 3D device deployment model and the efficient leakage model are combined to showcase the application of the presented leakage model, by studying the effect of stent size and the degree of stenosis on the regurgitant volume. The presented leakage model is also used to visualize the leakage path. To generalize the leakage model to a wide range of clinical applications, further validation on a large cohort of patients is needed to validate the accuracy of the model's prediction under various patient-specific conditions.

Lymphovascular invasion (LVI) is one of the most important prognostic factors in prostate cancer (PCa) and is correlated with worse survival rates, biochemical recurrence (BCR), and lymph node metastasis (LNM). The ability to predict LVI preoperatively in PCa may be useful for proposing variations in the diagnosis and management strategies. We performed a systematic review and meta-analysis to identify preoperative clinicopathological factors that correlate with LVI in final histopathological specimens in PCa patients. Systematic literature searches of PubMed, Embase, and Web of Science were performed up to 31 January 2023. A total of thirty-nine studies including 389,918 patients were included, most of which were retrospective and single-center. PSA level, clinical T stage, and biopsy Gleason score were significantly correlated with LVI in PCa specimens. Meta-analyses revealed that these factors were the strongest predictors of LVI in PCa patients. Prostate volume, BMI, and age were not significant predictors of LVI. A multitude of preoperative factors correlate with LVI in final histopathology. Meta-analyses confirmed correlation of LVI in final histopathology with higher preoperative PSA, clinical T stage, and biopsy Gleason score. This study implies advancements in risk stratification and enhanced clinical decision-making, and it underscores the importance of future research dedicated to validation and exploration of contemporary risk factors in PCa.

OBJECTIVE: Fenestrated endovascular aneurysm repair (FEVAR) has become a mainstay in treating complex aortic aneurysms, though baseline patient factors predicting long-term outcomes remain poorly understood. Proteinuria is an early marker for chronic kidney disease and associated with adverse cardiovascular outcomes, but its utility in patients with aortic aneurysms is unknown. We aimed to determine whether preoperative proteinuria impacts long-term survival after FEVAR. METHODS: A single-institution, retrospective review of all elective FEVAR was performed. Preoperative proteinuria was assessed by urinalysis: negative (0-29 mg/dL), 1+ (30-100 mg/dL), 2+ (101-299 mg/dL), and 3+ (≥300 mg/dL). The cohort was stratified by patients with proteinuria (≥30 mg/dL) vs those without (<30 mg/dL). Baseline, perioperative, and long-term outcomes were compared. The primary outcome, all-cause mortality, was evaluated by Kaplan-Meier analysis and independent predictors with Cox proportional hazards modeling. RESULTS: Among 181 patients who underwent standard FEVAR from 2012 to 2022 (mean follow-up 33 months), any proteinuria was noted in 30 patients (16.6%). Patients with proteinuria were more likely to be Black (10.0% vs 1.3%) with a lower estimated glomerular filtration rate (eGFR) (52.7 ± 24.7 vs 67.7 ± 20.5 mL/min/1.73 m2), higher Society for Vascular Surgery comorbidity score (10.9 ± 4.3 vs 8.2 ± 4.7) and calcium channel blocker therapy (50.0% vs 29.1%), and larger maximal aneurysm diameter (67.2 ± 16.9 vs 59.8 ± 9.8 mm) (all P < .05). Thirty-day mortality was higher in the proteinuria group (10.0% vs 1.3%; P = .03). Overall survival at 1 and 5 years was significantly lower for those with proteinuria (71.5% vs 92.3% and 29.5% vs 68.1%; log-rank P < .001). On multivariable analysis, preoperative proteinuria was independently associated with over threefold higher hazard of mortality (hazard ratio [HR]: 3.21, 95% confidence interval [CI]: 1.66-6.20; P < .001), whereas preoperative eGFR was not predictive (HR: 0.99, 95% CI: 0.98-1.01; P = .28). Additional significant predictors included chronic obstructive pulmonary disease (HR: 2.04), older age (HR: 1.05), and larger maximal aneurysm diameter (HR: 1.03; all P < .05). CONCLUSIONS: In our 10-year experience with FEVAR, preoperative proteinuria was observed in 17% of patients and was significantly associated with worse survival. In this cohort, proteinuria was independently associated with all-cause mortality, whereas eGFR was not, suggesting that urinalysis may provide an additional simple metric for risk-stratifying patients before FEVAR.

INTRODUCTION: Older adults with cancer who are being considered for cancer surgery are heterogenous, with variation in their physical, mental, and social baselines and risk of postoperative complications. Due in part to the complex nature of this population, the optimal preoperative evaluation method is not clearly defined. In this study we investigated whether geriatric-8 (G8), a screening tool for older patients with cancer that determines the need for a full geriatric assessment, is suitable for assessing the risk of postoperative complications in this population being considered for surgery. MATERIALS AND METHODS: Studies that enrolled older patients undergoing cancer surgery and compared prevalence of postoperative complications in G8 "high" (≥15) patients and G8 "low" (<15) patients were identified using PubMed and EMBASE. A meta-analysis was conducted to calculate the risk ratio of postoperative complication rate. Postoperative mortality was systematically reviewed. RESULTS: Eleven studies published between 2017 and 2022 were included in our analysis with a total of 2,691 older patients who underwent various types of cancer surgery and were characterized by their G8 scores: 1,255 G8 high (≥15) patients and 1,436 G8 low (<15) patients. G8 low patients had a significantly higher prevalence of postoperative complications than G8 high patients (risk ratio [95% confidence interval]: 1.56 [1.18-2.07], p = 0.002, I2 = 79%). DISCUSSION: G8 can be an effective and efficient preoperative tool to assess risk of postoperative complications in older adults undergoing cancer surgery and identify potential need for further evaluation of an individual's risk with a comprehensive geriatric assessment.

BACKGROUND: In breast cancer surgery, IBR (immediate breast reconstruction) is widely proposed to patients without indications of adjuvant treatments and without risk factors of surgical complications. New INCa's guidelines (2022) allow the expansion of IBR indications. OBJECTIVE: A retrospective, unicentric and safety study: post-operative complication rate after IBR in comparison with simple mastectomy (SM, reference treatment). MATERIEL AND METHOD: This retrospective study has included all major patients who have received mastectomy for breast cancer between 2016 and 2020 before application of new guidelines, in Hôpital de la Croix-Rousse, Lyon (France). They were distributed in two groups according to their surgery : IBR and SM. Usual risk factors of post-operative complications were collected (tabacco, obesity ). The primary endpoint was the occurrence of an early post-operative complication (within 3 months after surgery). Two secondary analysis focused on the impact of preoperative risk factors on complications, and the proportion of patients eligibled for an IBR among SM based on new INCA's guidelines. RESULTS: The study included 185 mastectomies: 153 SM, 32 mastectomies IBR. IBR's patients presented less risk factors, and few indications of adjuvant treatments. The rate of major complications was identical in the two groups (14 % in SM group, 12 % in IBR group), and there were more minor complications in the SM group than in the IBR group (p 0,01). According to our study, the raw proportion of initially possible IBR was 68 % (36 % of breast reconstruction in this study). CONCLUSION: This analyse approve IBR in selected patients. In this context, INCa's guidelines (2022) can generalize IBR's proposal to patients. However, the analysis of pre-operative risk factors stay essential in medical care.

OBJECTIVE: To determine the influence of intraoperative factors relative to preoperative risk factors on recovery after aortic root replacement (ARR). METHODS: Retrospective review of baseline and intraoperative characteristics was performed of 822 patients at our Aortic Center from 2005 to 2019. Inclusion criteria were all patients age 18 and older who underwent ARR at our institution from 2005 to 2019. The primary endpoint was the aggregate outcome of "failure to achieve uneventful recovery (FUR)," as previously defined. RESULTS: In total, 207 (25%) patients experienced FUR. The following preoperative and intraoperative variables were significantly associated with FUR in the multivariable analysis: cardiopulmonary bypass time (OR 1.01, 95% CI 1.01-1.02) open chest management (OR 5.67, 95% CI 2.65-12.1), ejection fraction (OR 1.03, 95% CI 1.01-1.04), chronic kidney disease > stage 3a (OR 2.37, 95% CI 1.54-3.63), bicuspid aortic valve (OR 1.54, 95% CI 1.21-1.96), and female sex (OR 1.30, 95% CI 1.06-1.61). Cardiopulmonary bypass time and open chest management were among the top three partial R2 contributors to the logistic regression model variance. CONCLUSIONS: These findings suggest efficacy in using intraoperative parameters to predict postoperative outcomes after ARR.

BACKGROUND: Preoperative COVID-19 testing protocols were widely implemented for children requiring surgery, leading to increased resource consumption and many delayed or canceled operations or procedures. This study using multi-center data investigated the relationship between preoperative risk factors, COVID-positivity, and postoperative outcomes among children undergoing common urgent and emergent procedures. METHODS: Children (<18 years) who underwent common urgent and emergent procedures were identified in the 2021 National Surgical Quality Improvement Program Pediatric database. The outcomes of COVID-positive and non-COVID-positive (negative or untested) children were compared using simple and multivariable regression models. RESULTS: Among 40,628 children undergoing gastrointestinal surgery (appendectomy, cholecystectomy), long bone fracture fixation, cerebrospinal fluid shunt procedures, gonadal procedures (testicular detorsion, ovarian procedures), and pyloromyotomy, 576 (1.4%) were COVID-positive. COVID-positive children had higher American Society of Anesthesiologists scores (p ≤ 0.001) and more frequently had preoperative sepsis (p ≤ 0.016) compared to non-COVID-positive children; however, other preoperative risk factors, including comorbidities, were largely similar. COVID-positive children had a longer length of stay than non-COVID-positive children (median 1.0 [IQR 0.0-2.0] vs. 1.0 [IQR 0.0-1.0], p < 0.001). However, there were no associations between COVID-19 positivity and overall complications, pulmonary complications, infectious complications, or readmissions. CONCLUSIONS: Despite increased preoperative risk factors, COVID-positive children did not have an increased risk of postoperative complications after common urgent and emergent procedures. However, length of stay was greater for COVID-positive children, likely due to delays in surgery related to COVID-19 protocols. These findings may be applicable to future preoperative testing and surgical timing guidelines related to respiratory viral illnesses in children. LEVEL OF EVIDENCE: III.

PURPOSE: This study aimed to investigate the association of effort-independent variables derived from the preoperative cardiopulmonary exercise test (CPET) with 30-day postoperative complications after elective colorectal surgery. METHODS: A multicenter (n=4) retrospective explorative study was performed using data of patients who completed a preoperative CPET and underwent elective colorectal surgery. The preoperative slope of the relation between minute ventilation and carbon dioxide production (VE/VCO2-slope) and the oxygen uptake efficiency slope (OUES), as well as 30-day postoperative complications, were assessed. Multivariable logistic regression analyses and receiver operating characteristic (ROC) curves were used to investigate the prognostic value of the relationship between these preoperative CPET-derived effort-independent variables and postoperative complications. RESULTS: Data from 102 patients (60.1% males) with a median age of 72.0 (interquartile range 67.8-77.4) years were analyzed. Forty-four patients (43.1%) had one or more postoperative complications (of which 52.3% general and 77.3% surgical complications). Merely 10 (9.8%) patients had a general complication only. In multivariate analysis adjusted for surgical approach (open versus minimally invasive surgery), the VE/VCO2-slope (odds ratio (OR) 1.08, confidence interval (CI) 1.02-1.16) and OUES (OR 0.94, CI 0.89-1.00) were statistically significant associated with the occurrence of 30-day postoperative complications. CONCLUSION: The effort-independent VE/VCO2-slope and OUES might be used to assist in future preoperative risk assessment and could especially be of added value in patients who are unable or unwilling to deliver a maximal cardiorespiratory effort. Future research should reveal the predictive value of these variables individually and/or in combination with other prognostic (CPET-derived) variables for postoperative complications.

Objectives: For years, many efforts have been invested to prepare patients, in particular, those with reduced physical and psychic status, much better to provide and finally achieve better outocme if there is time available to provide several beneficial measures. Methods: Therefore, the objective was to illustrate the concept and various single elements of a complex prehabilitation concept based on (i) selective references from the medical literature and (ii) own clinical experiences from clinical practice in general and abdominal surgery. Results: Prehabiliation can be considered the solution of the efforts to improve preoperative status for patients in a disadvantageous status for almost all types of surgery and all other operative and/or interventional procedures. It is the targeted process to improve individual functionality and organ function before a planned (elective) surgical intervention; P. comprises basically nutritional, physical and psychological measures; P. focusses especially onto the elderly, frail and malnourished patients before a planned surgical intervention; the overall aim is to significantly improve final outcome characterized by shorter length of stay, lower complication rate and mortality as well as cost efficiency; P. is especially important in cancer surgery, in which the beneficial effects can be particularly implemented; P. programs and/or "Standard Operating Protocols" (SOP) may help to establish and materialize its single aspects and enhanced recovery after surgery (ERAS). There is still further potential to reliably establish and to utilize the options of prehabilitation measures as listed above. Conclusions: Prehabiliation is an indispensable aspect in today's preparation for elective surgery, which needs to become obligatory part of the preparation measures to planned surgical interventions, which can further contribute to a better final outcome and ERAS as well as, in addtion, needs to be further developed and accomplished.
