Introduction Surgical repair is the standard of care for most infants and children with congenital heart disease. Cardiopulmonary bypass (CPB) is required to facilitate these operations but elicits a systemic inflammatory response, leading to postoperative organ dysfunction, morbidity and prolonged recovery after the surgery. Subzero-balance ultrafiltration (SBUF) has been shown to extract proinflammatory cytokines continuously throughout the CPB exposure. We hypothesize that a high-exchange SBUF (H-SBUF) will have a clinically relevant anti-inflammatory effect compared with a low-exchange SBUF (L-SBUF). Methods and analysis The ULTrafiltration to enhance Recovery After paediatric cardiac surgery (ULTRA) trial is a randomised, double-blind, parallel-group randomised trial conducted in a single paediatric cardiac surgery centre. Ninety-six patients less than 15 kg undergoing cardiac surgery with CPB will be randomly assigned to H-SBUF during CPB or L-SBUF during CPB in a 1:1 ratio with stratification by The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) score 1 and STAT score 2-5. The primary outcome is peak postoperative vasoactive-ventilation-renal score. Time series and peak values of vasoactive-ventilation renal score, vasoactive-inotrope score, ventilation index and oxygenation index will be collected. Secondary clinical outcomes include acute kidney injury, ventilator-free days, inotrope-free days, low cardiac output syndrome, mechanical circulatory support, intensive care unit length of stay and operative mortality. Secondary biomarker data include cytokine, chemokine and complement factor concentrations at baseline before CPB, at the end of CPB exposure and 24 hours following CPB. Analyses will be conducted on an intention-to-treat principle. Ethics and dissemination The study has ethics approval (#1024932 dated August 31, 2021) and enrolment commenced in September 2021. The primary manuscript and any subsequent analyses will be submitted for peer-reviewed publication. Trial registration number NCT04920643.
BackgroundThe inflammatory response to cardiopulmonary bypass (CPB) in pediatric patients remains an unresolved challenge. Sanguineous CPB prime, composed of allogenic blood products, is one potentially important stimulus. This study aims to identify specific inflammatory mediators active in sanguineous CPB prime and their impact on the inflammatory response at CPB initiation.MethodsIn a post-hoc analysis of a prospective observational cohort study (NCT05154864), where pediatric patients undergoing cardiac surgery with CPB were enrolled after informed consent, patients were grouped by CPB prime type (sanguineous vs crystalloid). Arterial samples were collected post-sternotomy as a baseline and again at CPB initiation from all patients. In the sanguineous group, CPB prime samples were also collected after buffered ultrafiltration but before CPB initiation. Luminex® measured concentrations of 24 inflammatory mediators for comparison between groups. Statistical analyses were by Mann-Whitney test and Wilcoxon signed-rank test. Data are presented as median [IQR].ResultsForty consecutive pediatric patients participated. The sanguineous group (n = 26) was younger (4.0 [0.2 - 6.0] vs 48.5 [39.0 - 69.5] months; p = 2.6 × 10-7) and smaller (4.9 [34 - 6.6] vs 17.2 [14.9 - 19.6] kg; p = 2.6 × 10-7) than the crystalloid group (n = 14). Despite this, baseline concentrations of 20 complement and cytokine concentrations were comparable between groups (p > 0.05) while four showed differences between groups (p < 0.05). The sanguineous prime contained supraphysiologic concentrations of complement mediators: C2, C3, C3a, C3b, and C5a. Correspondingly, upon CPB initiation, patients receiving sanguineous prime exhibited a significantly larger burden of C2, C3, C3b, C5, and C5a (p < 0.001) relative to the crystalloid group. Cytokine and chemokine mediators were present at trace levels in the sanguineous prime.ConclusionsSanguineous prime contains activated complement that accelerates the inflammatory response at CPB initiation in neonates and infants. Immunomodulatory interventions targeting complement during CPB prime preparation could offer substantial benefits for these vulnerable patients.
Abstract Background Cardiopulmonary bypass (CPB) causes systemic inflammation during pediatric cardiac surgery, which can contribute to post-operative organ dysfunction and prolonged recovery. This study aims to identify key inflammatory mediators related to this clinically significant immunologic response. Methods Pediatric patients were enrolled in a single-arm prospective clinical study (NCT05154864) and received standard cardiac operation, CPB and subzero-balance ultrafiltration. Arterial samples were taken before CPB initiation and immediately after weaning, and concentrations of 33 inflammatory mediators were assayed. A principal component analysis with hierarchical clustering (PCA-HCPC) included inflammatory mediator concentrations measured at the end of CPB, validated peak post-operative clinical scores, ventilation time and intensive care length of stay. Mahalanobis distance assessed statistical differences between clusters. Spearman’s correlation described the linear relationship between mediator concentrations at the end of CPB and intensive care length of stay. Results are median (IQR). Results Forty consecutive patients were enrolled; the majority were male (58%), age of 7.3 (1.7–39.0) months and weight of 6.7 (4.6–14.9) kg. The PCA-HCPC revealed activated complement factors along with all peak clinical scores and prolonged intensive care requirements in the same cluster. Cytokine, chemokine, and leukocyte adhesion molecule concentrations were found in two other distinct clusters (Mahalanobis distance = 16.5; p = 0.004 and Mahalanobis distance = 17.4; p = 5.8 × 10–4). Mediator concentrations of C2 (Rho = 0.50; p = 0.001), C3 (Rho = 0.58; p = 1.1 × 10–4), C3b (Rho = 0.47; p = 0.002), C5 (Rho = 0.48; p = 0.002) and C5a (Rho = 0.63; 1.7 × 10–5) showed linear correlations with intensive care unit length of stay. Conclusions Activated complement factors, but not pro-inflammatory cytokines or chemokines, were most related to cardiopulmonary dysfunction and prolonged recovery in this novel analysis. Investigation of therapies that inhibit complement to dampen CPB-associated inflammation and enhance recovery after pediatric cardiac surgery is warranted.

Background:The delivery of cardiothoracic health care is complex, and despite best efforts, adverse patient outcomes do occur. There is significant heterogeneity in morbidity and mortality rounds within and between institutions as well as undertones of a "blame and shame" culture prohibitive to meaningful quality assessment and improvement of patient care. The Quality Improvement and Patient Safety (QIPS) program was designed to address these issues. Methods:QIPS is built on the Donabedian model of quality and established phase-of-care adverse event analysis. It focuses on cultivating a culture of transparency. Every case review yields important demographic data, event factors, and the case inflection point, creating an institution-specific QIPS database. The QIPS format was presented by The Society of Thoracic Surgeons Workforce on Patient Safety at 2 Society of Thoracic Surgeons webinar series in December 2021 and August 2022. Descriptive data on both presentations were collected. Results:The December 2021 webinar had 75 unique viewers from 13 countries, and there were 343 asynchronous playbacks. The August 2022 webinar had 38 unique viewers from 9 countries and 310 asynchronous playbacks. Conclusions:The standardized QIPS methods allow consistent recording of event factors and the inflection point, which are root causes of case morbidity or mortality. Dedication to the program will build a granular databank and identify recurring individual or system issues to launch quality improvement initiatives that address institution-specific needs. QIPS is simple, effective, and reproducible and seeks to create a culture of patient-centered quality and excellence in cardiothoracic surgery programs.
Background Cardiopulmonary bypass (CPB) is associated with systemic inflammation, featuring increased levels of circulating pro-inflammatory cytokines. Intra-operative ultrafiltration extracts fluid and inflammatory factors potentially dampening inflammation-related organ dysfunction and enhancing post-operative recovery. This study aimed to define the impact of continuous subzero-balance ultrafiltration (SBUF) on circulating levels of major inflammatory mediators. Methods Twenty pediatric patients undergoing cardiac surgery, CPB and SBUF were prospectively enrolled. Blood samples were collected prior to CPB initiation (Pre-CPB Plasma) and immediately before weaning off CPB (End-CPB Plasma). Ultrafiltrate effluent samples were also collected at the End-CPB time-point (End-CPB Effluent). The concentrations of thirty-nine inflammatory factors were assessed and sieving coefficients were calculated. Results A profound increase in inflammatory cytokines and activated complement products were noted in plasma following CBP. Twenty-two inflammatory mediators were detected in the ultrafiltrate effluent. Novel mediators removed by ultrafiltration included cytokines IL1-Ra, IL-2, IL-12, IL-17A, IL-33, TRAIL, GM-CSF, ET-1, and the chemokines CCL2, CCL3, CCL4, CXCL1, CXCL2 and CXCL10. Mediator extraction by SBUF was significantly associated with molecular mass < 66 kDa (Chi 2 statistic = 18.8, Chi 2 with Yates’ correction = 16.0, p < 0.0001). There was a moderate negative linear correlation between molecular mass and sieving coefficient (Spearman R = − 0.45 and p = 0.02). Notably, the anti-inflammatory cytokine IL-10 was not efficiently extracted by SBUF. Conclusions CPB is associated with a burden of circulating inflammatory mediators, and SBUF selectively extracts twenty of these pro-inflammatory factors while preserving the key anti-inflammatory regulator IL-10. Ultrafiltration could potentially function as an immunomodulatory therapy during pediatric cardiac surgery. Trial registration ClinicalTrials.gov, NCT05154864.

Abstract Background We compared the health‐related quality of life (HRQOL) in patients undergoing trimodality therapy for resectable stage I‐III esophageal cancer. Methods A total of 96 patients were randomized to standard neoadjuvant cisplatin and 5‐fluorouracil chemotherapy plus radiotherapy (neoadjuvant) followed by surgical resection or adjuvant cisplatin, 5‐fluorouracil, and epirubicin chemotherapy with concurrent extended volume radiotherapy (adjuvant) following surgical resection. Results There was no significant difference in the functional assessment of cancer therapy‐esophageal (FACT‐E) total scores between arms at 1 year (p = 0.759) with 36% versus 41% (neoadjuvant vs. adjuvant), respectively, showing an increase of ≥15 points compared to pre‐treatment (p = 0.638). The HRQOL was significantly inferior at 2 months in the neoadjuvant arm for FACT‐E, European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ‐OG25), and EuroQol 5‐D‐3 L in the dysphagia, reflux, pain, taste, and coughing domains (p < 0.05). Half of patients were able to complete the prescribed neoadjuvant arm chemotherapy without modification compared to only 14% in the adjuvant arm (p < 0.001). Chemotherapy related adverse events of grade ≥2 occurred significantly more frequently in the neoadjuvant arm (100% vs. 69%, p < 0.001). Surgery related adverse events of grade ≥2 were similar in both arms (72% vs. 86%, p = 0.107). There were no 30‐day mortalities and 2% vs. 10% 90‐day mortalities (p = 0.204). There were no significant differences in either overall survival (OS) (5‐year: 35% vs. 32%, p = 0.409) or disease‐free survival (DFS) (5‐year: 31% vs. 30%, p = 0.710). Conclusion Trimodality therapy is challenging for patients with resectable esophageal cancer regardless of whether it is given before or after surgery. Newer and less toxic protocols are needed.
Background Our aim was to establish if presence of circulating tumor cells (CTCs) predicted worse outcome in patients with non-metastatic esophageal cancer undergoing tri-modality therapy. Methods We prospectively collected CTC data from patients with operable non-metastatic esophageal cancer from April 2009 to November 2016 enrolled in our QUINTETT esophageal cancer randomized trial (NCT00907543). Patients were randomized to receive either neoadjuvant cisplatin and 5-fluorouracil (5-FU) plus radiotherapy followed by surgical resection (Neoadjuvant) or adjuvant cisplatin, 5-FU, and epirubicin chemotherapy with concurrent extended volume radiotherapy following surgical resection (Adjuvant). CTCs were identified with the CellSearch® system before the initiation of any treatment (surgery or chemoradiotherapy) as well as at 6-, 12-, and 24-months post-treatment. The threshold for CTC positivity was one and the findings were correlated with patient prognosis. Results CTC data were available for 74 of 96 patients and identified in 27 patients (36.5%) at a median follow-up of 13.1months (interquartile range:6.8-24.1 months). Detection of CTCs at any follow-up visit was significantly predictive of worse disease-free survival (DFS;hazard ratio [HR]: 2.44; 95% confidence interval [CI]: 1.41-4.24; p =0.002), regional control (HR: 6.18; 95% CI: 1.18-32.35; p =0.031), distant control (HR: 2.93; 95% CI: 1.52-5.65; p =0.001) and overall survival (OS;HR: 2.02; 95% CI: 1.16-3.51; p =0.013). After adjusting for receiving neoadjuvant vs. adjuvant chemoradiotherapy, the presence of CTCs at any follow-up visit remained significantly predictive of worse OS ([HR]:2.02;95% [Cl]:1.16-3.51; p =0.013) and DFS (HR: 2.49;95% Cl: 1.43-4.33; p =0.001). Similarly, any observed increase in CTCs was significantly predictive of worse OS (HR: 3.14; 95% CI: 1.56-6.34; p =0.001) and DFS (HR: 3.34; 95% CI: 1.67-6.69; p <0.001). Conclusion The presence of CTCs in patients during follow-up after tri-modality therapy was associated with significantly poorer DFS and OS regardless of timing of chemoradiotherapy.
The use of cardiopulmonary bypass (CPB) can be associated with significant hemodilution, coagulopathy and a systemic inflammatory response for infants and children undergoing cardiac surgery. Intra-operative ultrafiltration has been used for decades to ameliorate these harmful effects. The novel combination of a continuous and non-continuous form of ultrafiltration, Subzero Balance Simple Modified Ultrafiltration (SBUF-SMUF) here described, seeks to enhance recovery from pediatric cardiac surgery and CPB.
Background Cardiac surgery with cardiopulmonary bypass (CPB) is associated with a systemic inflammatory syndrome that adversely impacts cardiopulmonary function and can contribute to prolonged postoperative recovery. Intra-operative ultrafiltration during CPB is a strategy developed by pediatric cardiac specialists, aiming to dampen the inflammatory syndrome by removing circulating cytokines and improving coagulation profiles during the cardiac operation. Although ultrafiltration is commonly used in the pediatric population, it is not routinely used in the adult population. This study aims to evaluate if randomized evidence supports the use of continuous intra-operative ultrafiltration to enhance recovery for adults undergoing cardiac surgery with CPB. Methods This systematic review and meta-analysis will include randomized controlled trials (RCT) that feature continuous forms of ultrafiltration during adult cardiac surgery with CPB, specifically assessing for benefit in mortality rates, invasive ventilation time and intensive care unit length of stay (ICU LOS). Relevant RCTs will be retrieved from databases, including MEDLINE, Embase, CENTRAL and Scopus, by a pre-defined search strategy. Search results will be screened for inclusion and exclusion criteria by two independent persons with consensus. Selected RCTs will have study demographics and outcome data extracted by two independent persons and transferred into RevMan. Risk of bias will be independently assessed by the Revised Cochrane Risk-of-Bias (RoB2) tool and studies rated as low-, some-, or high- risk of bias. Meta-analyses will compare the intervention of continuous ultrafiltration against comparators in terms of mortality, ventilation time, ICU LOS, and renal failure. Heterogeneity will be measured by the χ 2 test and described by the I 2 statistic. A sensitivity analysis will be completed by excluding included studies judged to have a high risk of bias. Summary of findings and certainty of the evidence, determined by the GRADE approach, will display the analysis findings. Discussion The findings of this systematic review and meta-analysis will summarize the evidence to date of continuous forms of ultrafiltration in adult cardiac surgery with CPB, to both inform adult cardiac specialists about this technique and identify critical questions for future research in this subject area. Systematic review registration This systematic review and meta-analysis is registered in PROSPERO CRD42020219309 ( https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020219309 ).
Background and Aim: The P2Y12 platelet receptor inhibitor ticagrelor is widely used in patients following acute coronary syndromes or in those who have received coronary stents. Bentracimab is a monoclonal antibody-based reversal agent that is being formally evaluated in a Phase 3 clinical trial. Here, we probe the knowledge, attitudes, and practice patterns of cardiac surgeons regarding their perioperative management of ticagrelor and potential application of a ticagrelor reversal agent. Methods: A questionnaire was developed by a working group of cardiac surgeons to inquire into participants’ practices and beliefs regarding ticagrelor and disseminated to practicing Canadian cardiac surgeons. Results: A total of 70 Canadian cardiac surgeons participated. Bleeding risk was identified as the most significant consideration when surgically revascularizing ticagrelor-treated patients (90%). There is variability in the duration of withholding ticagrelor prior to coronary artery bypass graft procedure in a stable patient; 44.3% wait 3 days and 32.9% wait 4 days or longer. Currently, 14.3% of cardiac surgeons prophylactically give platelet transfusions and/or fresh frozen plasma intraoperatively following protamine infusion in patients who have recently received ticagrelor. Interestingly, 47.1% of surveyed surgeons were aware of a reversal agent for ticagrelor, 91.4% of cardiac surgeons would consider utilizing a ticagrelor reversal agent if available, and 51.4% acknowledged that the introduction of such an agent would be a major advance in clinical practice. Conclusions: The present survey identified ticagrelor-related bleeding as a major concern for cardiac surgeons. Surgeons recognized the significant unmet need that a ticagrelor reversal agent would address.
BACKGROUND:Injection drug use-associated infective endocarditis (IDU-IE) is a growing epidemic. The objective of this survey was to identify the beliefs and practice patterns of Canadian cardiac surgeons regarding surgical management of IDU-IE. METHODS:A 30-question survey was developed by a working group and distributed to all practicing adult cardiac surgeons in Canada. Data were analyzed using descriptive statistics. RESULTS:Of 146 surgeons, 94 completed the survey (64%). Half of surgeons (49%) would be less likely to operate on patients with IE if associated with IDU. In the case of prosthetic valve IE owing to continued IDU, 36% were willing to reoperate once and 14% were willing to reoperate twice or more. Most surgeons required commitments from patients before surgery (73%), and most referred patients to addiction services (81%). Some surgeons would offer a Ross procedure (10%) or homograft (8%) for aortic valve IE, and 47% would consider temporary mechanical circulatory support. Whereas only 17% of surgeons worked at an institution with an endocarditis team, 71% agreed that there was a need for one at each institution. Most surgeons supported the development of IDU-IE-specific guidelines (80%). CONCLUSIONS:Practice patterns and surgical management of IDU-IE vary considerably across Canada. Areas of clinical unmet needs include the development of a formal addiction services referral protocol for patients, the development of an interdisciplinary endocarditis team, as well as the creation of IDU-IE clinical practice guidelines.
Fetal compressive intrapericardial teratoma is a rare and life-threatening condition, qualifying as a high-acuity low-occurrence (HALO) event. To prepare for delivery and immediate neonatal management, specialists from pediatric cardiology, cardiac surgery, maternal-fetal-medicine, neonatology, cardiac anesthesia, critical care, clinical perfusion, obstetrical nursing, and operating room nursing convened. An in situ operating room simulation was used to identify and introduce key team members, derive and practice the anticipated clinical management algorithm, position human and equipment resources strategically, and ensure that each specialist team was familiar with the environment and available equipment. As rehearsed in the simulation, the cesarean delivery of the patient and neonatal cardiac surgery was uncomplicated and yielded a favourable clinical outcome. A patient-specific HALO simulation preparation (PSHSP) can facilitate positive clinical outcomes and improve health care team confidence in HALO scenarios such as the birth of newborns anticipated to have cardiorespiratory instabilty.
INTRODUCTION:The use of cardiopulmonary bypass in pediatric cardiac surgery is associated with significant inflammation, fluid overload, and end-organ dysfunction yielding morbidity and mortality. For decades, various intraoperative ultrafiltration techniques such as conventional ultrafiltration, modified ultrafiltration (MUF), zero-balance ultrafiltration (ZBUF), and combination techniques (ZBUF-MUF) have been used to mitigate these toxicities and promote improved postoperative outcomes. However, there is currently no consensus on the ultrafiltration technique or strategy that yields the most benefit for infants and children undergoing open heart surgery.METHODS:A librarian-conducted PubMed literature search from 1990 to 2018 yielded 90 clinical studies or publications on the various forms of ultrafiltration and the impact on physiologic markers and clinical outcomes. All publications were reviewed, summarized, and conclusions synthesized. The data sets were not combined for systematic or meta-analysis due to significant heterogeneity in study protocols and patient populations.RESULTS:Modified ultrafiltration significantly promotes improved myocardial function, reduction in fluid overload, and reduced bleeding and transfusion complications. Furthermore, ZBUF has shown a consistent reduction in inflammatory cytokines and improved pulmonary function and compliance. There is conflicting evidence that MUF, ZBUF, and ZBUF-MUF culminate in reduced ventilation time and intensive care unit stay.CONCLUSION:Various modes of ultrafiltration have been shown to be associated with improved physiologic function or clinical outcomes in pediatric cardiac surgery. There are some inconsistent trial results that can be explained by heterogeneity in ultrafiltration, clinical staff preferences, and institution protocols. Ultrafiltration has some essential benefit as it is ubiquitously used at pediatric heart centers; however, the optimal protocol could be yet identified.
4052 Background: We compared the health-related quality-of-life (HRQOL) of standard neoadjuvant cisplatin and 5-FU chemotherapy plus radiotherapy (N) followed by surgical resection to adjuvant cisplatin, 5-FU, and epirubicin chemotherapy with concurrent extended volume radiotherapy (A) following surgical resection for resectable esophageal carcinoma. Methods: 96 patients with stage I to III resectable cancer of the esophagus were enrolled into a prospective randomized trial (NCT00907543) from April 2009 to November 2016. Patients were randomized into 2 groups: N (47 cases) and A (49 cases). The primary end point was HRQOL using the FACT-E at one year. The secondary endpoints included other HRQOL measures, overall survival (OS), disease-free survival (DFS), and adverse events. Results: The median follow-up was 5.0 years [95% CI :4.6 to 5.5]. The majority of patients had adenocarcinomas of the distal esophagus/gastroesophageal junction (80.9% vs 87.8%). The stage distribution was: I 9%; II 22%; III 58%; TxN0-1 10%. Using an intention-to-treat analysis there was no significant difference in the FACT-E total scores between arms at one year (p = 0.759), with 35.5% vs. 41.2% respectively showing an increase of ≥ 15 points ( a priori minimal clinical difference) compared to pre-treatment (p = 0.638). The HRQOL was temporarily significantly inferior at 2 months in the N arm for FACT-E, EORTC OG25, and EQ-5D-3L in the dysphagia, reflux, pain, taste, and coughing domains (p < 0.05). There were no 30-day mortalities but 2.1% vs. 10.2% 90-day mortalities (p = 0.204). There were no significant differences in either 5-year OS (37.9% vs 28.9%, p = 0.321) or DFS (34.0% vs 25.5%, p = 0.551. 48.9% of patients required chemotherapy to be modified or stopped in the N arm compared to 57.1% in the A arm (p = 0.421). 51.1% of patients were able to complete the prescribed N arm chemotherapy without modification compared to only 14.3% in the A arm (p < 0.001). Chemotherapy related adverse events significantly more frequent in the neoadjuvant arm (p < 0.05). Surgery related adverse events were significantly more frequent in the neoadjuvant arm (p < 0.05). Conclusions: Trimodality therapy is challenging for patients with resectable esophageal cancer regardless if it is given before or after surgery. Less toxic protocols are needed.

Circulating tumor cells (CTC) correlate with poor prognosis in metastatic esophageal cancer, but there are few data describing the importance of CTCs in patients with non-metastatic disease. Our aim was to establish if CTCs predicted worse outcome in patients with non-metastatic esophageal cancer. We prospectively collected CTC data from patients with operable non-metastatic esophageal cancer from April 2009 to November 2016 enrolled in our QUINTETT esophageal cancer clinical trial (NCT00907543). Patients were randomized to receive either adjuvant or neoadjuvant chemoradiotherapy plus surgery. CTCs were enumerated with the CellSearch® system (Menarini Silicon Biosystem, Philadelphia, PA) before the initiation of any treatment (surgery, or chemoradiotherapy) as well as at 6, 12 , and 24 months post-treatment. CTC findings were correlate with standard tumor characteristics, including tumor size, and grade. Oncological outcomes were examined using Kaplan Meier estimates and Cox proportional hazards regression. CTCs were identified in 26 of 74 patients (35%) at a median follow up of 12.7months (interquartile range: 6.8-23.9 months). Detection of CTCs at any follow-up visit was significantly predictive of worse disease free survival (p=0.004), regional control (p=0.042), distant control (p<0.001) and overall survival (p=0.034). After adjusting for receiving neoadjuvant vs. adjuvant chemoradiotherapy, the presence of CTCs at any follow-up visit remained significantly predictive of worse overall survival (hazard ratio:1.82[HR];95% confidence interval [Cl]:1.03-3.22; p=0.04) and disease free survival (HR: 2.26 ;95% Cl: 1.29-3.97; p=0.005). Similarly, any observed increase in CTCs was significantly predictive of worse overall survival (HR: 2.70; 95% CI: 1.30-5.62; p=0.008) and disease free survival (HR: 2.92; 95% CI: 1.43-5.95; p=0.003). Patients with positive CTCs post trimodality therapy was associated with significantly poorer disease free and overall survival regardless of timing of chemoradiotherapy. Further investigation is warranted for the role of CTCs as a prognostic indicator in management of advanced non-metastatic esophageal cancer.
Background. Our vision was to develop an inexpensive training simulation in a functional operating room (in situ) that included surgical trainees and nursing and anesthesia staff to focus on effective interprofessional communication and teamwork skills. Methods. The simulation scenario revolved around an airway obstruction by residual tumor after pneumonectomy. This model included our thoracic operating room with patient status displayed by an open access vital sign simulator and a reversibly modified Laerdal airway mannequin (Shavanger, Norway). The simulation scenario was run seven times. Simulations were video recorded and scored with the use of Non-Technical Skills for Surgeons (NOTSS) and TeamSTEPPS2. Latent safety threats (LSTs) and feedback were obtained during the debriefing after the simulation. Feedback was captured with the Method Material Member Overall (MMMO) questionnaire. Results. Several LSTs were identified, which included missing and redundant equipment and knowledge gaps in participants' roles. Consultant surgeons received a higher overall score than thoracic surgery fellows on both NOTSS (3.8 versus 3.3) and TeamSTEPPS2 (4.1 versus 3.2) evaluations, suggesting that the scenario effectively differentiated learners from experts with regards to nontechnical skills. The MMMO overall simulation experience score was 4.7 of 5, confirming a high-fidelity model and useful experiential learning model. At the Canadian Thoracic Bootcamp, the MMMO overall experience score was 4.8 of 5, further supporting this simulation as a robust model. Conclusions. An inexpensive in situ intraoperative crisis simulation model for thoracic surgical emergencies was created, implemented, and demonstrated to be effective as a proof of concept at identifying latent threats to patient safety and differentiating the nontechnical skills of trainees and consultant surgeons.

OBJECTIVE Endoscopic resection of pituitary adenomas has been reported to improve vision function in up to 80%-90% of patients with visual impairment due to these adenomas. It is unclear how these reported rates translate into improvement in visual outcomes and general health as perceived by the patients. The authors evaluated self-assessed health-related quality of life (HR-QOL) and vision-related QOL (VR-QOL) in patients before and after endoscopic resection of pituitary adenomas. METHODS The authors prospectively collected data from 50 patients who underwent endoscopic resection of pituitary adenomas. This cohort included 32 patients (64%) with visual impairment preoperatively. Twenty-seven patients (54%) had pituitary dysfunction, including 17 (34%) with hormone-producing tumors. Patients completed the National Eye Institute Visual Functioning Questionnaire and the 36-Item Short Form Health Survey preoperatively and 6 weeks and 6 months after surgery. RESULTS Patients with preoperative visual impairment reported a significant impact of this condition on VR-QOL preoperatively, including general vision, near activities, and peripheral vision; they also noted vision-specific impacts on mental health, role difficulties, dependency, and driving. After endoscopic resection of adenomas, patients reported improvement across all these categories 6 weeks postoperatively, and this improvement was maintained by 6 months postoperatively. Patients with preoperative pituitary dysfunction, including hormone-producing tumors, perceived their general health and physical function as poorer, with some of these patients reporting improvement in perceived general health after the endoscopic surgery. All patients noted that their ability to work or perform activities of daily living was transiently reduced 6 weeks postoperatively, followed by significant improvement by 6 months after the surgery. CONCLUSIONS Both VR-QOL and patient's perceptions of their ability to do work and perform other daily activities as a result of their physical health significantly improved by 6 months after endoscopic resection of pituitary adenoma. The use of multidimensional QOL questionnaires provides a precise assessment of perceived outcomes after endoscopic surgery.
BACKGROUND:We present a rare complication of bilateral caudate infarcts and necrosed nasoseptal flaps after endoscopic transsphenoidal resection of tuberculum sellae meningioma. This case highlights the importance of early and accurate diagnosis and treatment of a postoperative cerebrospinal fluid (CSF) leak and associated bacterial meningitis, and reviews any existing guidelines regarding its management.CASE DESCRIPTION:A 54-year-old otherwise healthy man presented with progressive bitemporal hemianopsia. Magnetic resonance imaging of the head revealed a large, homogeneously enhancing sellar and suprasellar mass consistent with a meningioma. An endoscopic endonasal transsphenoidal approach was performed to resect the tuberculum sellae meningioma. The patient developed basal bacterial meningitis secondary to a CSF leak, requiring repair on two separate occasions. At the time of both repairs, there was evidence of necrosis of the nasoseptal flaps used for the repairs. Soon after the diagnosis of meningitis, the patient developed bilateral caudate infarcts.CONCLUSION:This report discusses the possible underlying etiologies for the bilateral caudate infarcts and necrosed flaps including bacterial meningitis with associated local vasospasm of nearby vessels resulting in infarction. This case emphasizes the importance of concise management of postendoscopic CSF leak and discusses the guidelines regarding antimicrobial therapy and the management of lumbar drains.
