Multidisciplinary care in nonmalignant central airway obstruction.

The management of histologically benign central airway obstruction (CAO) is complex. Published studies have focused on the diagnostic approaches and therapeutic options provided by specific specialties, but there has been no focus on multidisciplinary management of this disease. Our objective is to review the current diagnostic and therapeutic modalities available for managing nonmalignant CAO from a multidisciplinary perspective involving otolaryngology, thoracic surgery and interventional bronchoscopists. For benign airway strictures, management is via medical and endoscopic therapy with surgical resection reserved for complex and recurrent stenoses. There is evidence and growing interest in intralesional corticosteroid injection in treating inflammation and potentially preventing recurrence. Airway specialists from distinct disciplines use different laser types, dilating balloons and anesthesia methods to manage benign CAO. Recent studies have demonstrated substantial improvements in patient breathlessness and quality of life following therapeutic airway interventions, highlighting the evolving landscape in this cross-disciplinary field. Nonmalignant CAO, arising from various mechanical, inflammatory, and infectious etiologies, poses significant morbidity and mortality risks. Current treatments include endoscopic resection, dilation, stent placement, and surgical resection which are selected based on lesion's complexity, extent, operability and patient's symptoms and goals. A multimodal and multidisciplinary approach to patient care could offer the best outcomes.

Impact of intravenous infusion of lidocaine on intrapulmonary shunt and postoperative cognitive function in patients undergoing one-lung ventilation.

Intravenous infusion of lidocaine as an anesthesia adjuvant can improve patient outcomes, but its impact on intrapulmonary shunt during one-lung ventilation (OLV) has not been clarified. To determine the effect of intravenous lidocaine infusion on intrapulmonary shunt during OLV and postoperative cognitive function in video-assisted thoracoscopic surgery (VATS). Sixty patients who underwent OLV for thoracic surgery were randomized to receive intravenous infusion of lidocaine (lidocaine group, n = 30) or normal saline (control group, n = 30) for anesthesia induction. Arterial and venous blood gases were measured during two-lung ventilation and at 15 and 30 min after OLV (OLV + 15 and OLV + 30). The Mini-Mental State Examination was administered before the surgery and at postoperative 12 months to assess patient cognitive function. No significant difference was found in intrapulmonary shunt fraction (Qs/Qt) between the lidocaine group and the control group at OLV + 15 (p = 0.493) and OLV + 30 (p = 0.754). The lidocaine group used significantly lower doses of propofol and remifentanil compared to the control group (both p < 0.001). Furthermore, no significant difference was observed in the incidence of postoperative cognitive dysfunction between the lidocaine group and the control group at 1 year post-operation (3.3% vs 6.7%, p = 0.554). Intravenous lidocaine administered in VATS had no significant impact on intrapulmonary shunt during OLV or postoperative cognitive function. However, it significantly reduced the doses of anesthetics used during the surgery.

The prevalence and associated factors of intraoperative hypotension following thoracic surgery in resources limited area, 2023. multi-centre approach

Background: Hypotension is an independent predictor of long-term patient morbidity and duration of hospital stay. Multiple factors contribute to the development of intraoperative hypotension. Prevention and treatment of these factors may reduce patients’ hypotension and its associated morbidity and mortality. This study aimed to assess the prevalence and associated factors of intraoperative hypotension in patients undergoing elective thoracic surgery. Methods: This institution-based cross-sectional study was conducted among 174 adult patients who underwent elective thoracic surgery. A systematic random sampling technique was used, and quantitative data were collected through interviews and data retrieval from charts via a pretested questionnaire. Both bivariable and multivariable logistic regression analyses were performed to evaluate the associations between independent and dependent variables. The level of statistical significance was defined as a P-value less than 0.05. The data were entered into Info 7.2.1 and analysed via SPSS version 26 software, which was used to calculate descriptive statistics, and bivariate and multivariate logistic regression were performed. Results: In general, information was collected from 174 patients during the study period. The results of the present study revealed that 65 (41%) patients developed intraoperative hypotension (95% CI: 36.43%-48%). Intraoperative blood loss was significantly associated with intraoperative hypotension [AOR=9.58, 95% CI (2.57--35.8)] (P=0.001). Conclusion and recommendation: The findings of this study revealed high rates of intraoperative hypotension episodes, which were 41%, in patients who underwent elective thoracic surgery. Age, ASA class, type of intraoperative blood loss, type of procedure pre-existence comorbidity and duration of surgery were predictors of intraoperative hypotension in patients who underwent elective thoracic surgery. The anaesthetist’s, surgeon and PACU staff’s understanding of these factors is very crucial for close follow-up of this group of patients.

Trends in Medicare Utilization and Reimbursement of Tracheostomy From 2000 to 2022.

To analyze the utilization and reimbursement for tracheostomy. Retrospective Cross-Sectional Study. Centers for Medicare & Medicaid Services (CMS) Medicare Provider Utilization and Payment Data (2013 and 2021) and Part B Medicare Fee-For-Service National Summary Data (2000-2022). Utilization, payment, and specialty breakdown were analyzed for planned tracheostomy (Current Procedural Terminology [CPT] codes 31600, 31601, 31610) and emergency tracheostomy (CPT codes 31603, 31605). From 2000 to 2022, there was a 48.9% decrease (40,754-20,812) in number of planned tracheostomies and a 75.3% decrease (3277-811) in number of emergency tracheostomies, leading to an overall decrease of 51%. Similarly, there was a 59.3% inflation-adjusted decrease ($13.4-$5.5 million) in total reimbursement for planned tracheostomies and an 82.1% inflation-adjusted decrease ($1.1 million-$205 thousand) in total reimbursement for emergency tracheostomies. There was a 20.3% inflation-adjusted decrease ($329-$262) in reimbursement per planned tracheostomy and a 27.7% inflation-adjusted decrease ($349-$252) in reimbursement per emergency tracheostomy. In our sample of 280 high-volume tracheostomy providers in 2021 (28.2% otolaryngology, 28.2% general surgery, 14.6% thoracic surgery, 14.3% pulmonary disease, 6.4% critical care), the average provider performed 15.8 tracheostomies and was reimbursed $5362. Despite significant declines in tracheostomy utilization and reimbursement, understanding trends for these lifesaving procedures are critical for otolaryngologists and other providers in delivering high-quality care, and can be used by surgeons, hospital systems, and policymakers to guide future health care legislation.

The long lost denture: a rare case of an acquired, non-malignant tracheo-oesophageal fistula

BackgroundIngested dental prosthesis are susceptible to impaction in the gastrointestinal tract due to their sharp edges, size and contour. Delays in presentation arise from the lack of clear history of ingestion and misdiagnosis occurs due to the radiolucency of denture material on plain radiography. An acquired, non-malignant tracheo-oesophageal fistula (TOF) may develop from a chronically impacted denture. Surgical management of a TOF secondary to denture is a challenging clinical problem that is rarely reported in the literature and no previous case reports have described the two-staged reconstruction approach that we present here.Case presentationWe report a case of a male in his early 60s who presented to an acute general hospital with symptoms ongoing for over one year of dysphagia, recurrent chest infections and weight loss. Barium swallow and computed tomography identified an ingested dental prosthesis (denture) that had caused a TOF. He was transferred to our specialist thoracic surgery unit where an attempt to remove the foreign body endoscopically was abandoned due to firm impaction and risk of further injury. The subsequent multi-disciplinary management of this complex case required a two-staged reconstruction approach. The first procedure involved extracting the foreign body, repairing the underlying defects with tracheal resection and anastomosis, and creating an oesophageal diversion with cervical oesophagostomy. The second procedure achieved continuity of the gastrointestinal tract with gastric pull-up and pharyngo-gastric anastomosis. Following rehabilitation, the patient was discharged on oral intake alongside percutaneous jejunostomy feeding.ConclusionsEarly recognition and removal of impacted dental prosthesis is essential to prevent morbidity and mortality. Delayed diagnosis can lead to acquired TOF with associated consequences such as recurrent pulmonary infection, mediastinitis and nutritional deficit. Challenges we encountered, such as failed attempts at endoscopic retrieval and the difficult dissection of fibrotic tissue, were directly due to the delayed identification of the denture. We highlight the importance of holding a high index of clinical suspicion of foreign body ingestion in dental prosthesis wearers who present with recurrent chest infections and ongoing dysphagia. We also promote the need for a collaborative multi-disciplinary approach in the surgical management of complex cases.

Effectiveness of refined nursing intervention on postoperative recovery and respiratory function in lung cancer patients after thoracic surgery.

To evaluate the effectiveness of refined nursing intervention versus routine nursing care in improving respiratory function and facilitating their recovery in lung cancer patients after thoracic surgery. Total 75 primary lung cancer patients (average age: 55.3 ± 10.8 years) who underwent thoracic surgery at Tangshan People's Hospital from February 2024 to July 2024 were included in the study. According to the different postoperative nursing intervention, patients were randomized into control group (CG) and observational group (OG) for evaluating the effects of refined nursing intervention on pain relief, postoperative recovery and respiratory function. Tidal volume, vital capacity, forced expiratory volume in 1 second, peak expiratory flow, and maximal voluntary ventilation were used to evaluate pulmonary function. The Medical Outcomes Study 36-Item Short-Form Health Survey and Nursing Intensive-Care Satisfaction Scale were administered at the minimum of 30 days of nursing interventions after thoracic surgery to assess quality of life and satisfaction with nursing care respectively. Bivariate correlation analysis and chi-square test (χ2) were used to analyze significant changes by using SPSS (version 27.0). About 61% (n = 46) of the patients were female. Routine nursing care was conducted in both CG and OG patients, while in OG simultaneously received refined nursing care. After a period of nursing intervention, recovery rate of heart and pulmonary was significantly higher than CG (92.31% vs 72.22%, P = .022) with a lower incidence of postoperative complications (12.82% vs 30.56%, P = .049). Pulmonary function test results revealed a significant improvement in OG patients' tidal volume (0.43 ± 0.06 vs 0.39 ± 0.07, P = .014), vital capacity (3.53 ± 0.30 vs 3.34 ± 0.32, P = .020), forced expiratory volume in 1 second (4.67 ± 0.67 vs 4.23 ± 0.58, P = .003), peak expiratory flow (4.76 ± 0.51 vs 4.36 ± 0.51, P = .001) and maximal voluntary ventilation (58.22 ± 7.86 vs 53.70 ± 6.89, P = .010) compared to CG. Postoperative moderate-to-worst pain duration in OG was significantly shortened (4.36 ± 1.56 vs 5.81 ± 1.94, P < .001), while health status value was higher (60.87 ± 5.89 vs 56.53 ± 6.22, P = .003). Moreover, OG expressed higher satisfaction with nursing care compared to CG (P = .002). Patients experienced reduced respiratory function after thoracic surgery. Refined nursing intervention might facilitate patients' postoperative recovery and improve their respiratory function and general well-being, which would be beneficial for achieving patients' satisfaction and promoting positive interaction between patients and multidisciplinary team members.

Machine Learning on 50,000 Manuscripts Shows Increased Clinical Research by Academic Cardiac Surgeons

IntroductionAcademic cardiac surgeons are productive researchers and innovators. We sought to perform a comprehensive machine learning (ML)-based characterization of cardiac surgery research over the past 40 y to identify trends in research pursuits. MethodsUS-based academic websites were queried for surgeon profiles. Publications since 1980 were obtained from Web of Science, and publication classifications (e.g., “human”, “animal”) were collected through the National Institutes of Health iCite tool. Publications were deemed “basic or translational” if >50% of their classification was under “animal” or “molecular or cell”, and “clinical” if otherwise. ML-based clustering was performed on publication titles and Medical Subject Heading terms to identify research topics. ResultsA total of 944 cardiac surgeons accounted for 48,031 unique publications. Average citations per year have decreased since 1980 (P < 0.001). The percentage of basic or translational publications by cardiac surgeons has decreased over time (P < 0.001), comprising of only 8% of publications in 2022. Adult cardiac surgeons, those who received an F32, K08, or R01, and those with a PhD were more likely to publish basic or translational research. Top areas of basic or translational research were myocardial reperfusion, aortic aneurysms or remodeling, and transplant immunology. Major areas of clinical research included aortic disease, aortic valve disease, and mechanical circulatory support. Collaboration analysis revealed that 55% of publications were single-center, and the yearly percentage of these publications has decreased over time (P < 0.001). ConclusionsCardiac surgeons are performing less basic or translational research relative to clinical research than ever before. The majority of publications over the past 40 y did not involve cross-center collaboration. Continued support for clinical research is needed, while also encouraging collaborative basic or translational science to foster innovation in patient care.

A multidisciplinary approach in the treatment of thoracic endometriosis

Purpose. To familiarize gynecologists with the clinical presentation, diagnosis and basic principles of treatment of thoracic endometriosis (TE).Materials and Methods. The article presents a review of publications based on the results of search in electronic resources PubMed, Elibrary, EMBASE. The own clinical observation of the patient with TE is also presented.Results. The clinical picture of TE can be different, in many patients it is asymptomatic. The typical symptom of TE is menstrual cycle-related, usually right-sided pain in the thoracic, scapular or shoulder area. Chest X-rays, computed tomography (CT), magnetic resonance imaging (MRI) and bronchoscopy are used in diagnosis. The gold standard for definitive diagnosis and effective treatment is video-assisted thoracoscopic surgery (VATS). As with pelvic disease, the first-line therapy for TE is medication to suppress ovarian steroid hormone production. Surgical treatment should be considered in patients with refractory or recurrent TE and in acute life-threatening conditions.Conclusion. Management of patients with thoracic endometriosis requires an interdisciplinary approach involving gynecologists and thoracic surgeons.

Asian Pacific Society of Cardiology Position Statement on the Use of Transcatheter Aortic Valve Implantation in the Management of Aortic Stenosis

Transcatheter aortic valve implantation (TAVI) has been established as an effective treatment modality in patients with severe aortic stenosis and the uptake of TAVI is rapidly growing in the Asia-Pacific region. However, there exists a heterogeneity in the management of aortic stenosis and the use of TAVI among countries in the region. Reasons for these differences include anatomical variations, disparity in healthcare resources and infrastructure and the lack of consensus on the optimal management of aortic stenosis in the Asia-Pacific region. Hence, an Asian Pacific Society of Cardiology (APSC) working group, including a multidisciplinary group of general and interventional cardiologists, cardiac surgeons and imaging specialists, developed a position statement on the recommendations for TAVI in the management of aortic stenosis. The APSC expert panel reviewed and appraised the available evidence using the Grading of Recommendations Assessment, Development, and Evaluation system. Recommendations were developed and put to an online vote. Consensus was reached when 80% of votes for a given recommendation were in support of ‘agree’ or ‘neutral.’ The resulting 28 statements provide guidance for clinical practitioners in the region on the use of TAVI in the treatment of patients with aortic stenosis.

Tricuspid regurgitation: a contemporary review.

Tricuspid regurgitation (TR), an underrecognized disease, overlooked by clinicians for many years due to its assumed benign nature. Recent epidemiological studies suggest significant TR may be seen in up to 6% of elderly patients. An increase in prevalence is expected due to the higher incidence of various clinical predictors of TR progression. Increasing severity of TR is associated with worse outcomes with a novel morphologic classification providing a more refined prediction of outcomes. Advances in cardiac imaging, particularly echocardiography, are integral to the diagnosis of disease severity which not only includes quantitation of TR, but also an assessment of the right atrium, right ventricle and pulmonary arterial circulation. Once identified and quantified, TR management requires a multi-disciplinary heart team management including structural imagers, heart failure specialists, electrophysiologist, cardiac surgeons and interventionalists. Data to support medical therapies are lacking although guidelines support the management of congestive signs and symptoms, as well as comorbidities such as left heart failure and rhythm management. The risks of surgical interventions are slowly improving, however, transcatheter therapies are now available to treat patients with high surgical risk. This manuscript will provide a state-of-art review of this fast-moving field, including current scientific evidences, but also upcoming perspectives with multiple ongoing clinical studies.

Patient-reported harm following cancellation of planned surgery at a Danish university hospital: a cross-sectional study.

To estimate the prevalence and severity of patient-reported physical and non-physical harm following surgery cancellation. Cross-sectional study. A large Danish university hospital. Patients (≥18 years) from various surgical specialities, such as orthopaedic, spinal, abdominal, gynaecological, thoracic, vascular and urological surgery whose surgery was cancelled <2 weeks prior to the scheduled date due to hospital-related causes.OutcomePatient-reported physical and non-physical harm, defined as physical worsening, emotional strain and other consequences, measured using a patient-reported survey. We identified 785 patients whose surgery was cancelled from 1 December 2021 to 1 June 2022, of whom 436 (55.5%) responded to the electronic survey. Physical worsening was reported by 42% and emotional strain by 48% of patients. One-third of patients reported an inability to continue daily activities, and 28% reported a need for an increased dose of analgesics. Emotional strain included various negative feelings such as being disappointed (59%) and lonely (31%). Furthermore, 44% of the respondents feared deterioration of their disease and 9% experienced anxiety of dying. The relative risk of emotional strain was higher in females than in males (54% vs 41%, adjusted relative risk (RR)=1.32 (1.08; 1.63)). A waiting period >30 days compared with ≤30 days was associated with a higher risk of physical worsening (25.3% vs 48.9%, adjusted RR=1.93 (1.42; 2.63)). Harm, measured as physical worsening and emotional strain, is reported with severity by nearly half of respondents following cancellation.

Successful use of ultrasound guided pecto-intercostal fascial plane block to provide intraoperative analgesia in four dogs undergoing median sternotomy.

To evaluate the impact of pecto-intercostal fascial plane block on providing intraoperative analgesia in dogs undergoing median sternotomy. 4 dogs. The dogs were presented with a history of inappetence, lethargy and respiratory distress. Thoracic radiographs, point of care ultrasound, thoracocentesis, bronchoscopy and computed tomography was performed to characterize the disease. 4 male castrated, 5.3 ± 3 years old dogs weighing 19.7 ± 13.5 kg and belonging to Dalmatian, Beagle, Siberian Husky and Rottweiler breeds were included. Three dogs were diagnosed with suppurative pleural effusions because of pulmonary abscesses and one dog with spontaneous pneumothorax due to the presence of pulmonary bullae. All dogs underwent median sternotomy under general anesthesia to explore the thorax. A pecto-intercostal fascial plane block was performed by injecting local anesthetic bupivacaine in the parasternal fascial plane between the deep pectoral and external intercostal muscles to provide antinociception by anesthetizing ventral cutaneous branches of intercostal nerves second through sixth. Analgesia from the block resulted in reduced requirement of inhalant anesthesia and minimal requirement for opioid to augment analgesia intraoperatively. Median sternotomy is required to perform thoracic surgery in dogs with various thoracic pathologies. Pecto-intercostal fascial plane block is a locoregional technique that can blunt nociception arising from the ventral thorax and can significantly improve perioperative patient care in dogs undergoing median sternotomy by providing effective intraoperative and potentially postoperative analgesia.

Ectopic Calcification in Congenital Heart Surgery: A Material-Centric Review.

The modern congenital heart surgeon has an array of materials available for cardiovascular repair. With advancements in the surgical outcomes for pediatric cardiac defects, choice of material has become increasingly dependent on late-term complications associated with each material. Calcification is a leading long-term complication and is increasing in prevalence with materials lasting longer in patients. Material calcification can impair functionality, lead to subsequent complications, and require additional interventions. A comprehensive literature review was conducted to investigate ectopic calcification of commonly used materials for congenital heart defect repair. Mechanisms of ectopic calcification among commonly used materials were investigated. Ectopic calcification is initiated by material-specific immunological reactions. Recent efforts have focused on developing new materials that are not prone to calcification. ePTFE was widely used in cardiovascular applications but still has reported instances of calcification in various situations, such as long-term use. Tissue engineering techniques have shown reduced calcification in reports. Calcification can occur in all conventional materials we reviewed and, in some cases, has led to life-threatening complications. Favorable outcomes have been reported with tissue-engineered materials, with the expectation of continued positive results in future reports. With an array of synthetic and biological materials now displaying acceptable surgical and short-term outcomes, there is a pressing need to review the long-term viability of these materials, especially considering improved patient survival to adulthood. Furthermore, developing new materials to mitigate calcification remains a promising avenue of research in this field.

Comparing surgical outcomes of powered versus manual surgical staplers: a systematic review and meta-analysis.

The growing use of staplers, manual and powered, especially in minimally invasive surgeries, necessitates evaluating their efficacy in gastrointestinal and thoracic surgeries. Parameters analysed include anastomotic and air leakage rates, bleeding, infection, cost, and operative duration. We searched Cochrane Library, CINAHL, EMBASE, PubMed, and Web of Science using terms like "surgical staplers," "manual staplers," "automatic staplers," and "powered staplers." We assessed study quality using the Joanna Briggs Institute (JBI) Critical Appraisal tools and conducted meta-analysis using Review Manager software. A total of 43,104 patients with a mean age of 60.8 were involved in the studies. The meta-analysis revealed a significant reduction in anastomotic leaks in GI surgery patients (OR 0.31, p = 0.0001) and a significant decrease in postoperative air leakage in thoracic surgery patients (OR 0.65, p = 0.05) when powered staplers were employed. Additionally, we observed a significant decline in hemostasis-related complications for both thoracic and GI surgeries (OR 0.48, p = 0.002) with the use of powered staplers. Although individually costlier than manual staplers, powered staplers significantly decreased total hospitalisation costs (MD -1725.82, p < 0.00001) amoungst the thoracic surgeries, due to the cost saved on remedying the lower rate of complications compared to manual staplers. It also decreased the average operative times in thoracic and GI surgeries, although not significant (p = 0.06, p = 0.07 respectively). Powered staplers surpass manual staplers by reducing operative duration, total hospital costs, and complications like anastomotic leaks and bleeding. Hence, they are poised to become the preferred alternative in future surgeries.

Intraoperative short-term blood pressure variability and postoperative acute kidney injury: a single-center retrospective cohort study using sample entropy analysis

BackgroundTo investigate if intraoperative very short-term variability in blood pressure measured by sample entropy improves discrimination of postoperative acute kidney injury after noncardiac surgery.MethodsAdult surgical patients undergoing general, thoracic, urological, or gynecological surgery between August 2016 to June 2017 at Seoul National University Hospital were included. The primary outcome was acute kidney injury stage 1, defined by the Kidney Disease: Improving Global Outcomes guidelines. Exploratory and explanatory variables included sample entropy of the mean arterial pressure and standard demographic, surgical, anesthesia and hypotension over time indices known to be associated with acute kidney injury respectively. Random forest classification and L1 logistic regression were used to assess four models for discriminating acute kidney injury: (1) Standard risk factors which included demographic, anesthetic, and surgical variables (2) Standard risk factors and cumulative hypotension over time (3) Standard risk factors and sample entropy (4) Standard risk factors, cumulative hypotension over time and sample entropy.ResultsTwo hundred and thirteen (7.4%) cases developed postoperative acute kidney injury. The median and interquartile range for sample entropy of mean arterial pressure was 0.34 and [0.26, 0.42] respectively. C-statistics were identical between the random forest and L1 logistic regression models. Results demonstrated no improvement in discrimination of postoperative acute kidney injury with the addition of the sample entropy of mean arterial pressure: Standard risk factors: 0.81 [0.76, 0.85], Standard risk factors and hypotension over time indices: 0.80 [0.75, 0.85], Standard risk factors and sample entropy of mean arterial pressure: 0.81 [0.76, 0.85] and Standard risk factors, sample entropy of mean arterial pressure and hypotension over time indices: 0.81 [0.76, 0.86].ConclusionAssessment of very short-term blood pressure variability does not improve the discrimination of postoperative acute kidney injury in patients undergoing non-cardiac surgery in this sample.

Comparison of Ultrasound-Guided Single-Injection Erector Spinae Plane Block, Retrolaminar Block and Paravertebral Block for Postoperative Analgesia in Single-Incision Video-Assisted Thoracoscopic Surgery: A Three-Arm, Double-Blind, Randomized Controlled Non-Inferiority Trial.

Effective postoperative analgesia is critical for thoracic surgery. This study compares the analgesic efficacy of the erector spinae plane block (ESPB), retrolaminar block (RLB), and paravertebral block (TPVB) in single-incision video-assisted thoracoscopic surgery (SITS). Seventy-six patients underwent general anesthesia followed by ultrasound-guided nerve blocks with 20mL of 0.5% ropivacaine. Primary outcomes included the area under the curve (AUC) of Numeric Rating Scale (NRS) scores during rest and coughing over 24 hours. Secondary outcomes included perioperative opioid use, plasma biomarkers, and postoperative recovery measures. The AUC for NRS was 107.8±10.53 in the ESPB group, 104.8±8.05 in the RLB group, and 103.6±10.42 in the TPVB group, demonstrating non-inferiority for ESPB (difference: 4.2±3.0, 95% CI -1.82 to 10.22) and RLB (difference: 1.2±2.6, 95% CI -3.97 to 6.37) compared to TPVB. No significant differences were observed in opioid use, plasma biomarkers, QoR-15 scores, or adverse events. ESPB and RLB provide non-inferior analgesia compared to TPVB in SITS patients and are effective alternatives that enhance safety.

Aortic Stent Graft Treatment in a Medium-Size Aortic Center Performed by a Cardiac Surgeon Only—The 9 Years Experience in Poland

Background: The incidence of thoracic aortic aneurysms is estimated at 3.0–8.3/100,000 persons per year. There is a lack of reports in the literature on the outcomes of small- and medium-sized thoracic endovascular aortic repairs. The aim of this study is to present the results of thoracic endovascular aortic repairs at a single medium-sized center performed exclusively by a cardiac surgeon. Methods: Ninety patients who had undergone aortic stent graft implantations for the treatment of thoracic aortic anomalies were comprehensively, retrospectively evaluated. The detailed preoperative, surgical, and postoperative parameters of the patients, including the survival rate up to five years, were recorded and further analyzed. Results: The patients’ Euroscores were four (2.1–9). The 30-day mortality rate was 8.9%, the 1-year mortality rate was 15.6%, and the 5-year mortality rate was 38.9% for all causes. Postoperative complications were observed in 10% of the patients. Statistically significant differences were observed between the urgency of surgery at 30 days and survival at one year, but not at five years. The most common complications were related to respiratory (4.4%), renal (3.3%), and neurological (3.3%) dysfunction. Conclusions: Thoracic endovascular aortic repair can be safely performed in small- and medium-sized centers with optimal long-term results.

Postoperative lymphopaenia as a risk factor for postoperative infections in cancer surgery: A prospective multicentre cohort study (the EVALYMPH study).

Stress due to surgical trauma decreases postoperative lymphocyte counts (LCs), potentially favouring the occurrence of postoperative infections (PIs). We aimed to determine whether postoperative lymphopaenia following thoracic or gastrointestinal cancer surgery is an independent risk factor for PIs and to identify modifiable factors related to anaesthesia and surgical procedures that might affect its occurrence. The EVALYMPH study was a prospective, multicentre cohort study with a 30-day patient follow-up. Multivariate analyses were performed to determine the risk factors for PIs and for postoperative lymphopaenia. Patients were included from January 2016 to September 2017 in 25 French centres. Adult patients admitted for thoracic or gastrointestinal cancer surgery were eligible for inclusion. PIs within 30 days after surgery were defined as urinary tract infections, pneumonia, surgical site infections and other infections (bloodstream infections or pleurisy). Of 1207 patients included, 273 (22.6%) developed at least one infection within 30 days after surgery, with a median [IQR] time to onset of 8 [5 to 11] days. An increased risk of PI was significantly associated with an ASA score of IV: hazard ratio (HR) 4.27 (95% confidence interval (CI), 1.87 to 9.72), surgery > 200 min (HR 1.58 (1.15 to 2.17) and lymphopaenia on postoperative day 1 (POD1) (HR 1.56 (1.08 to 2.25). This risk was associated with changes in postoperative LC over time (P = 0.001) but not with preoperative LC (P = 0.536).POD1 lymphopenia was related to patient characteristics and duration of surgery but not to potentially modifiable other surgical or anaesthetics factors. POD1 lymphopaenia was associated with PIs in patients undergoing thoracic or gastrointestinal cancer surgery. To individualise care, patient characteristics and surgery duration should be taken into account. ClinicalTrials.gov Identifier: NCT02799251.
