    Title translation Prédicteurs d’insuffisance rénale aiguë après une chirurgie de résection pulmonaire : une étude cas témoins rétrospective.
    Abstract Purpose: Patients undergoing lung resection are at increased risk for acute kidney injury (AKI) in the immediate postoperative period, with important consequences for longer term morbidity and mortality. Lung resection surgery has unique considerations that could increase the risk of AKI, including lung resection volume, duration of one-lung ventilation (OLV), and intraoperative fluid restriction. Yet, specific risk factor data are lacking. The objective of this study was to identify independent risk factors for early AKI after lung resection surgery.
    Methods: We conducted a retrospective case-control study of all patients presenting for elective lung resection surgery at an academic medical centre over a four-year period. Cases were patients who experienced an AKI and control patients were those who did not experience an AKI, based on KDIGO criteria. Baseline demographics and comorbidities along with duration of OLV and amount of lung resected were collected by retrospective chart review. The data were analyzed using multivariable logistic regression to identify independent predictors of AKI.
    Results: Acute kidney injury occurred within 48 hr in 57/1,045 (5.5%; 95% confidence interval, 4.2 to 7.0) of patients. On multivariable analysis, our model of best fit included preoperative serum creatinine, male sex, use of angiotensin II receptor blockers, and duration of OLV. The rate of complications, intensive care unit admission, and risk of death were all higher in the group of patients who experienced AKI.
    Conclusions: Acute kidney injury occurs frequently after lung resection surgery and is associated with increased risk of postoperative complications. Increased duration of OLV may be a risk factor for AKI in this population.

    Abstract Objective: Disposable instrument use during video-assisted thoracoscopic lobectomy is a significant driver of cost. The purpose of the study was to measure the effect of increasing surgeon cost awareness via successive "value improvement initiatives" on instrument costs.
    Methods: We prospectively collected disposable instrument use data for all video-assisted thoracoscopic lobectomies performed by 5 Board-certified thoracic surgeons over 4 successive time periods: Period 1: control group of consecutive video-assisted thoracoscopic lobectomies before interventions; Period 2: video-assisted thoracoscopic lobectomies after displaying disposables price list in operating room; Period 3: video-assisted thoracoscopic lobectomies after educational presentation outlining disposable instrument price differences; Period 4: video-assisted thoracoscopic lobectomies after surgeon self-assessment with peer comparison of cost data from Period 3 and positive deviance seminar identifying the lowest-cost surgeon to lead discussion of optimal cost-reduction strategies. Instrument use and costs were compared among the 4 groups using the Kruskal-Wallis test.
    Results: A total of 373 lobectomy cases were analyzed. Compared with Period 1, median stapler-related and total disposable costs for video-assisted thoracoscopic lobectomy cases decreased after successive value improvement initiatives, with lowest costs in Period 4 (P < .0001). Multiple linear regression analysis demonstrated per lobectomy disposables cost reduction of $397.53 in Period 4, after controlling for surgeon and lobe (P < .0001). Operating room time was reduced after successive value improvement initiatives (P < .0001).
    Conclusions: Cost awareness and surgeon engagement activities were associated with sustained cost reduction for video-assisted thoracoscopic lobectomies. Surgeon self-assessment, peer comparison, and positive deviance seminar were associated with the largest cost reduction. Significant hospital cost-savings may be realized with surgeon-led value improvement initiatives.

    Abstract In thoracic surgery, disposable instruments are significant drivers of cost. There is variation in disposable instrument use among surgeons. It was hypothesized that a "passive awareness" intervention (displaying a pricing list of disposable instruments in the operating theater) would decrease operative costs. A current price list of disposable instruments used in thoracoscopic lobectomy was displayed in the thoracic surgery operating theater. Consecutive patients who underwent thoracoscopic lobectomy 6 months prior to price list display (Period 1) and 6 months following price list display (Period 2) were analyzed. Descriptive statistics were used to describe case distribution and lobectomy costs. T test and linear regression were used to examine the impact of surgeon, lobe removed, and time period. Over the study period, 71 patients underwent thoracoscopic lobectomy (Period 1: n = 36, Period 2: n = 35). Median per-lobectomy disposables cost decreased from $2063.22 (Interquartile range [IQR] $788.49) in Period 1 to $1885.92 (IQR $552.26) in Period 2; p = 0.03. There was a significant reduction in the median number of "high cost disposables" between Periods 1 and 2 (5.5-5.0, respectively; p = 0.04). In multiple linear regression, there was a decrease in total per-lobectomy cost of $286.21 (p = 0.03) and a decrease in stapler cartridge cost of $266.89 (p = 0.03) when controlling for surgeon and lobe. There was a significant reduction in disposable instrument expenditure per thoracoscopic lobectomy following posting of instrument costs in the operating theater. These findings suggest that a simple passive awareness intervention is effective in influencing surgeon behavior to reduce disposable instrument costs.

    Abstract Objective: Preoperative distress is commonly experienced by surgical patients and is associated with adverse health-related outcomes. Research suggests preoperative distress may be elevated among cancer surgery patients relative to other surgical groups and there appears to be greater recognition of the adverse impacts of distress for these patients. This study examined associations between preoperative distress and postoperative healthcare-related correlates (e.g., length of stay, re-hospitalization) among a large, mixed surgical sample, and separately among cancer surgery patients with active cancer.
    Methods: We analyzed secondary data from the Vascular Events In Non-cardiac Surgery Patients Cohort Evaluation (VISION) study - Mental Health Supplement (N = 997; n = 370 active cancer/cancer surgery). The Kessler 6-item Psychological Distress Scale assessed preoperative distress on the day of surgery. Multivariable regressions examined associations between distress and healthcare-related correlates. For significant relationships, we examined associations between anxiety and depressive subscales of distress with the correlates of interest.
    Results: Among the full surgical sample, after adjustment, preoperative distress was associated with a greater length of stay (b = 0.01, 95% CI [0.00-0.02], R
    Conclusions: Findings suggest preoperative distress may be associated with greater postoperative healthcare needs. Results support the importance of screening for distress in the perioperative period.

    Abstract Background: It is unclear how positive end-expiratory pressure (PEEP) and recruitment maneuvers impact patients during one-lung ventilation (OLV). We conducted a systematic review and meta-analysis of the effect of lung recruitment and PEEP on ventilation and oxygenation during OLV.
    Methods: A systematic review and random-effects meta-analysis were performed. Mean difference with standard deviation was calculated. Included studies were evaluated for quality and risk of bias using the Cochrane Risk of Bias tool and the modified Newcastle-Ottawa Score where appropriate.
    Results: In total, 926 articles were identified, of which 16 were included in meta-analysis. Recruitment maneuvers increased arterial oxygen tension (PaO
    Conclusions: Recruitment maneuvers and PEEP have physiologic advantages during OLV. The optimal use of PEEP is yet to be determined. The evidence is limited by heavy use of surrogate outcomes. Future studies with clinical outcomes are necessary to determine the impact of recruitment maneuvers and PEEP during OLV.

    Abstract Background: The selection of tidal volumes for 1-lung ventilation remains unclear, because there exists a trade-off between oxygenation and risk of lung injury. We conducted a systematic review and meta-analysis to determine how oxygenation, compliance, and clinical outcomes are affected by tidal volume during 1-lung ventilation.
    Methods: A systematic search of MEDLINE and EMBASE was performed. A systematic review and random-effects meta-analysis was conducted. Pooled mean difference estimated arterial oxygen tension, compliance, and length of stay; pooled odds ratio was calculated for composite postoperative pulmonary complications. Risk of bias was determined using the Cochrane risk of bias and Newcastle-Ottawa tools.
    Results: Eighteen studies were identified, comprising 3693 total patients. Low tidal volumes (5.6 [±0.9] mL/kg) were not associated with significant differences in partial pressure of oxygen (-15.64 [-88.53-57.26] mm Hg; P = .67), arterial oxygen tension to fractional intake of oxygen ratio (14.71 [-7.83-37.24]; P = .20), or compliance (2.03 [-5.22-9.27] mL/cmH2O; P = .58) versus conventional tidal volume ventilation (8.1 [±3.1] mL/kg). Low versus conventional tidal volume ventilation had no significant impact on hospital length of stay (-0.42 [-1.60-0.77] days; P = .49). Low tidal volumes are associated with significantly decreased odds of pulmonary complications (pooled odds ratio, 0.40 [0.29-0.57]; P < .0001).
    Conclusions: Low tidal volumes during 1-lung ventilation do not worsen oxygenation or compliance. A low tidal volume ventilation strategy during 1-lung ventilation was associated with a significant reduction in postoperative pulmonary complications.

    Abstract Background: Histologic confirmation of malignancy has been indicated for a suspicious lung nodule prior to resection. The purpose of this study was to determine whether or not foregoing routine tissue biopsy increased the incidence of lobectomy for benign lesions.
    Methods: Retrospective cohort of 256 patients who underwent thoracoscopic or open lobectomy for a confirmed or suspected pulmonary malignancy, with or without tissue diagnosis. Clinical, radiographic, and pathologic data were compared.
    Results: Among 256 patients, 127 had attempted biopsy (group A) and 129 had no biopsy procedure (group B). There was no significant difference in the incidence of benign resections between the groups (Group A = 4 (3.2%) benign pathology vs group B = 9 (7.0%; P = 0.16). Group B had significantly lower operative time (127.1 vs 112.3 minutes; P = 0.004) and intraoperative complications (23 vs 37 patients; P = 0.03). There was a trend toward longer hospital stay and surgical waiting time in group A (6.6 vs 5.2 days, P = 0.24; 92.4 vs 66.2 days; P = 0.14, respectively).
    Conclusion: Foregoing biopsies and proceeding to lobectomy in selected patients with suspicious lung nodules is safe, did not increase the incidence of resected benign pathology, and may decrease surgical wait time. Patients should be carefully evaluated and counseled.

    Abstract Metabolomics analysis of blood from patients (n = 42) undergoing surgery for suspected lung cancer was performed in this study. Venous and arterial blood was collected in both Streck and Heparin tubes. A total of 96 metabolites were detected, affected by sex (n = 56), collection tube (n = 33), and blood location (n = 8). These metabolites belonged to a wide array of compound classes including lipids, acids, pharmaceutical agents, signalling molecules, vitamins, among others. Phospholipids and carboxylic acids accounted for 28% of all detected compounds. Out of the 33 compounds significantly affected by collection tube, 18 compounds were higher in the Streck tubes, including allantoin and ketoleucine, and 15 were higher in the Heparin tubes, including LysoPC(P-16:0), PS 40:6, and chenodeoxycholic acid glycine conjugate. Based on our results, it is recommended that replicate blood samples from each patient should be collected in different types of blood collection tubes for a broader range of the metabolome. Several metabolites were found at higher concentrations in cancer patients such as lactic acid in Squamous Cell Carcinoma, and lysoPCs in Adenocarcinoma and Acinar Cell Carcinoma, which may be used to detect early onset and/or to monitor the progress of the cancer patients.
