RESUMO
Sternal resection and reconstruction is a rare but sometimes challenging procedure due to its profound anatomical and functional implications. For these reasons, an adequate preoperative evaluation is crucial in each patient, especially when we are faced with malignant lesions that sometimes require extensive radical resections, thus demanding an integrated reconstructive strategy that allows stabilizing the chest wall, protecting the underlying mediastinum and minimize resulting deformity. The large number of available reconstruction techniques and the lack of quality studies for their analysis mean that sternal reconstruction depends to a great extent on the consensus of experts or, more frequently, on the simple preference of each surgical team. This article aims to provide an overview of sternal resection and reconstruction. Indications for partial versus total or subtotal sternectomy are suggested and their surgical and oncological outcomes are presented. The use of rigid or semi-rigid prostheses is an ongoing debate, although recent functional data advise reserving rigid reconstructions for extensive defects. Sternectomy for primary tumors or local tumor involvement has a good prognosis with an overall survival of 5 and 10 years: 67% and 58%, respectively, provided that a radical resection with free surgical margins is performed. Breast cancer is the most common secondary sternal tumor, and surgery can offer 5-year overall survival ranging from 20% to 50% provided an R0 resection is achieved, although radical surgery does not appear to decrease rates. of recurrence. Metastases of origin other than the breast give the worst results (less than 40% at 36 months and 0% at 5 years) and although the data available on these cases are limited, the radicality of the resection does not seem to modify the survival or recurrence rates, so a conservative approach is probably more appropriate.
RESUMO
Background: Rescue failure has been described as an important factor that conditions postoperative mortality after surgical interventions. The objective of this study is to determine the incidence and main determinants of failure to rescue after anatomical lung resections. Methods: Prospective multicenter study that included all patients undergoing anatomical pulmonary resection between December 2016 and March 2018 and registered in the Spanish nationwide database GEVATS. Postoperative complications were classified as minor (grades I and II) and major (grades IIIa to V) according to the Clavien-Dindo standardized classification. Patients that died after a major complication were considered rescue failure. A stepwise logistic regression model was created to identify predictors of failure to rescue. Results: 3,533 patients were analyzed. In total, 361 cases (10.2%) had major complications, of which 59 (16.3%) could not be rescued. The variables associated with rescue failure were: ppoDLCO% (OR, 0.98; 95% CI, 0.96-1; p = 0.067), cardiac comorbidity (OR, 2.1; 95% CI, 1.1-4; p = 0.024), extended resection (OR, 2.26; 95% CI, 0.94-5.41; p = 0.067), pneumonectomy (OR, 2.53; 95 CI, 1.07-6.03; p = 0.036) and hospital volume <120 cases per year (OR, 2.53; CI 95%, 1.26-5.07; p = 0.009). The area under the curve of the ROC curve was 0.72 (95% CI: 0.64-0.79). Conclusion: A significant percentage of patients who presented major complications after anatomical lung resection did not survive to discharge. Pneumonectomy and annual surgical volume are the risk factors most closely related to rescue failure. Complex thoracic surgical pathology should be concentrated in high-volume centers to obtain the best results in potentially high-risk patients.
RESUMO
BACKGROUND: Prolonged air leak (PAL) is the most frequent complication after pulmonary resection. Several measures have been described to prevent the occurrence of PAL in high-risk patients, however, the potential role of mesenchymal stem cells (MSCs) applied in the parenchymal suture line to prevent postoperative air leak in this setting has not been fully addressed. OBJECTIVE: To analyse the feasibility, safety and potential clinical efficacy of the implantation of autologous MSCs embedded in Tissucol Duo® as a prophylactic alternative to prevent postoperative prolonged air leak after pulmonary resection in high-risk patients. STUDY DESIGN: Phase I/II single-arm prospective clinical trial. METHODS: Six patients with high risk of PAL undergoing elective pulmonary resection were included. Autologous bone marrow-derived MSCs were expanded at our Good Manufacturing Practice (GMP) Facility and implanted (embedded in a Tissucol Duo® carrier) in the parenchymal suture line during pulmonary resection surgery. Patients were monitored in the early postoperative period and evaluated for possible complications or adverse reactions. In addition, all patients were followed-up to 5 years for clinical outcomes. RESULTS: The median age of patients included was 66 years (range: 55-70 years), and male/female ratio was 5/1. Autologous MSCs were expanded in five cases, in one case MSCs expansion was insufficient. There were no adverse effects related to cell implantation. Regarding efficacy, median air leak duration was 0 days (range: 0-2 days). The incidence of PAL was nil. Radiologically, only one patient presented pneumothorax in the chest X-ray at discharge. No adverse effects related to the procedure were recorded during the follow-up. CONCLUSIONS: The use of autologous MSCs for prevention of PAL in patients with high risk of PAL is feasible, safe and potentially effective. TRIAL REGISTRATION NO: EudraCT: 2013-000535-27.

To investigate factors associated with the ability to receive adjuvant chemotherapy in patients with pathological N1 and N2 stage after anatomic lung resections for non-small cell lung cancer (NSCLC). Multicenter retrospective analysis on 707 consecutive patients found pathologic N1 (pN1) or N2 (pN2) disease following anatomic lung resections for NSCLC (2014-2019). Multiple imputation logistic regression was used to identify factors associated with adjuvant chemotherapy and to develop a model to predict the probability of starting this treatment. The model was externally validated in a population of 253 patients. In the derivation set, 442 patients were pN1 and 265 pN2. 58% received at least 1 cycle of adjuvant chemotherapy. The variables significantly associated with the probability of starting chemotherapy after multivariable regression analysis were: younger age (p < 0.0001), Body Mass Index (BMI) (pâ¯=â¯0.031), Forced Expiratory Volume in 1 second (FEV1) (pâ¯=â¯0.037), better performance status (PS) (p < 0.0001), absence of chronic kidney disease (CKD) (pâ¯=â¯0.016), resection lesser than pneumonectomy (pâ¯=â¯0.010). The logit of the prediction model was: 6.58 -0.112 x age +0.039 x BMI +0.009 x FEV1 -0.650 x PS -1.388 x CKD -0.550 x pneumonectomy. The predicted rate of adjuvant chemotherapy in the validation set was 59.2 and similar to the observed 1 (59%, pâ¯=â¯0.87) confirming the model performance in external setting. This study identified several factors associated with the probability of initiating adjuvant chemotherapy after lung resection in node-positive patients. This information can be used during preoperative multidisciplinary meetings and patients counseling to support decision-making process regarding the timing of systemic treatment.

Background: Surgical technique plays an essential role in achieving good health outcomes. However, the quality of surgical technique reporting remains heterogeneous. Reporting checklists could help authors to describe the surgical technique more transparently and effectively, as well as to assist reviewers and editors evaluate it more informatively, and promote readers to better understand the technique. We previously developed SUPER (surgical technique reporting checklist and standards) to assist authors in reporting their research that contains surgical technique more transparently. However, further explanation and elaboration of each item are needed for better understanding and reporting practice. Methods: We searched surgical literature in PubMed, Google Scholar and journal websites published up to January 2023 to find multidiscipline examples in various article types for each SUPER item. Results: We explain the 22 items of the SUPER and provide rationales item by item alongside. We provide 69 examples from 53 literature that present optimal reporting of the 22 items. Article types of examples include pure surgical technique, and case reports, observational studies and clinical trials that contain surgical technique. Examples are multidisciplinary, including general surgery, orthopaedical surgery, cardiac surgery, thoracic surgery, gastrointestinal surgery, neurological surgery, oncogenic surgery, and emergency surgery etc. Conclusions: Along with SUPER article, this explanation and elaboration file can promote deeper understanding on the SUPER items. We hope that the article could further guide surgeons and researchers in reporting, and assist editors and peer reviewers in reviewing manuscripts related to surgical technique.
RESUMO
Background: Existing reporting guidelines pay insufficient attention to the detail and comprehensiveness reporting of surgical technique. The Surgical techniqUe rePorting chEcklist and standaRds (SUPER) aims to address this gap by defining reporting standards for surgical technique. The SUPER guideline intends to apply to articles that encompass surgical technique in any study design, surgical discipline, and stage of surgical innovation. Methods: Following the EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network approach, 16 surgeons, journal editors, and methodologists reviewed existing reporting guidelines relating to surgical technique, reviewed papers from 15 top journals, and brainstormed to draft initial items for the SUPER. The initial items were revised through a three-round Delphi survey from 21 multidisciplinary Delphi panel experts from 13 countries and regions. The final SUPER items were formed after an online consensus meeting to resolve disagreements and a three-round wording refinement by all 16 SUPER working group members and five SUPER consultants. Results: The SUPER reporting guideline includes 22 items that are considered essential for good and informative surgical technique reporting. The items are divided into six sections: background, rationale, and objectives (items 1 to 5); preoperative preparations and requirements (items 6 to 9); surgical technique details (items 10 to 15); postoperative considerations and tasks (items 16 to 19); summary and prospect (items 20 and 21); and other information (item 22). Conclusions: The SUPER reporting guideline has the potential to guide detailed, comprehensive, and transparent surgical technique reporting for surgeons. It may also assist journal editors, peer reviewers, systematic reviewers, and guideline developers in the evaluation of surgical technique papers and help practitioners to better understand and reproduce surgical technique.

RESUMO
OBJECTIVES: The relationship between operating time and postoperative morbidity has not been fully characterized in lung resection surgery. We aimed to determine the variables associated with prolonged operative times and their influence on postoperative complications after video-thoracoscopic lobectomy. METHODS: Patients undergoing thoracoscopic lobectomy for lung cancer from December 2016 to March 2018, within the prospective registry of the Spanish Video-Assisted Thoracic Surgery Group were identified. Operating time was stratified by quartiles and complication rates analysed using chi-squared test. Primary outcomes included 30-day overall, pulmonary and cardiovascular complications and wound infection. Multivariable logistic regression analyses were performed to identify variables independently associated with operating time and their influence on the occurrence of postoperative complications. RESULTS: Data of 1518 cases were examined. The median operating time was 174 min (interquartile range: 130-210 min). Overall morbidity rates significantly increased with surgical duration (20.5% vs 34.4% in the 1st and 4th quartiles, respectively, P < 0.05) and so did pulmonary complications (14.6% vs 26.4% in the 1st and 4th quartiles, respectively, P < 0.05). Differences were not found regarding cardiovascular and wound complications. After multivariable logistic regression analysis, operating time remained as an independent risk factor for overall (odds ratios, 2.05) and pulmonary complications (odds ratios, 2.01). Male sex, predicted postoperative diffusing capacity of the lung for carbon monoxide, number of lymphatic stations harvested, pleural adhesions, fissures completeness, lobectomy site, surgeon seniority, individual video-thoracoscopic surgeon experience and fissureless technique were identified as predictive factors for long operative time. CONCLUSIONS: Prolonged operating time is associated with increased odds of postoperative complications. Modifiable factors contributing to prolonged operating time may serve as a target for quality improvement.

OBJECTIVES: Robotic surgery, although it shares some technical features with video-assisted thoracoscopic surgery (VATS), offers some advantages, such as ergonomic design and a 3-dimensional view. Thus, the learning curve for robotic lung resection could be expected to be shorter than that of VATS for surgeons who are proficient in VATS. The goal of this study was to analyse the robotic learning curve of a VATS experienced surgeon and to compare it to his own VATS learning curve for anatomical lung resections. METHODS: We conducted a retrospective observational study based on the prospectively recorded data of the first 150 anatomical lung resections performed with VATS (75 cases) and with the robotic (75 cases) approach by the same surgeon in our centre. Learning curves were analysed using the cumulative sum method to assess the trends for total operating time and surgical failure (intraoperative complications, conversion, technical postoperative complications and reintervention) across case sequences. Subsequently, using adequate statistical tests, we compared the postoperative outcomes in both groups. RESULTS: The median operating time was similar for both approaches (P = 0.401). Surgical failure rate was higher for the robotic cases (21.3% vs 12%; P = 0.125). Based on cumulative sum analyses, operating time decreased starting with case 34 in the VATS group and with case 32 in the robotic cohort. Surgical failure tended to decline starting with case 28 in the VATS group and with case 32 in the robotic group. Perioperative results were similar in both groups. CONCLUSIONS: When we compared robotic and VATS learning curves for anatomical lung resection, we did not find any differences. Postoperative outcomes were also similar with both approaches.

INTRODUCTION: The paradoxical benefit of obesity, the 'obesity paradox', has been analyzed in lung surgical populations with contradictory results. Our goal was assessing the relationship of body mass index (BMI) to acute outcomes after minimally invasive major pulmonary resections. METHODS: Retrospective review of consecutive patients who underwent pulmonary anatomical resection through a minimally invasive approach for the period 2014-2019. Patients were grouped as underweight, normal, overweight and obese type I, II and III. Adjusted odds ratios regarding postoperative complications (overall, respiratory, cardiovascular and surgical morbidity) were produced with their exact 95% confidence intervals. All tests were considered statistically significant at p<0.05. RESULTS: Among 722 patients included in the study, 37.7% had a normal BMI and 61.8% were overweight or obese patients. When compared with that of normal BMI patients, adjusted pulmonary complications were significantly higher in obese type I patients (2.6% vs 10.6%, OR: 4.53 [95%CI: 1.86-12.11]) and obese type II-III (2.6% vs 10%, OR: 6.09 [95%CI: 1.38-26.89]). No significant differences were found regarding overall, cardiovascular or surgical complications among groups. CONCLUSIONS: Obesity has not favourable effects on early outcomes in patients undergoing minimally invasive anatomical lung resections, since the risk of respiratory complications in patients with BMI≥30kg/m2 and BMI≥35kg/m2 is 4.5 and 6 times higher than that of patients with normal BMI.

INTRODUCTION: Outcomes after the introduction of surgical innovations can be impaired by learning periods. The aim of this study is to compare the short-term outcomes of a recently implemented RATS approach to a standard VATS program for anatomical lung resections. METHODS: Retrospective review of consecutive patients undergoing pulmonary anatomical resection through a minimally invasive approach since RATS approach was applied in our department (June 01, 2018, to November 30, 2019). Propensity score matching was performed according to patients' age, gender, ppoFEV1, cardiac comorbidity, type of malignancy, and type of resection. Outcome evaluation includes: overall morbidity, significant complications (cardiac arrhythmia, pneumonia, prolonged air leak, and reoperation), 30-day mortality, and length of hospital stay. Data were compared by two-sided chi-square or Fisher's exact test for categorical and Mann-Whitney U test for continuous variables. RESULTS: A total of 273 patients (206 VATS, 67 RATS) were included in the study. After propensity score matching, data of 132 patients were analyzed. The thirty-days mortality was nil. Overall morbidity (RATS: 22.4%, VATS: 29.2%; p=0.369), major complications (RATS: 9% vs VATS: 9.2%; p=0.956) and the rates of specific major complications (cardiac arrhythmia RATS: 4.5%, VATS: 4.6%, p=1; pneumonia RATS:0%, VATS:4.6%, p=0.117; prolonged air leak RATS: 7.5%; VATS: 4.6%, p=0.718) and reoperation (RATS: 3%, VATS: 1.5%, p=1) were comparable between both groups. The median length of stay was 3 days in both groups (p=0.101). CONCLUSIONS: A RATS program for anatomical lung resection can be implemented safely by experienced VATS surgeons without increasing morbidity rates.

INTRODUCTION: The aim of this study was to develop a surgical risk prediction model in patients undergoing anatomic lung resections from the registry of the Spanish Video-Assisted Thoracic Surgery Group (GEVATS). METHODS: Data were collected from 3,533 patients undergoing anatomic lung resection for any diagnosis between December 20, 2016 and March 20, 2018. We defined a combined outcome variable: death or Clavien Dindo grade IV complication at 90 days after surgery. Univariate and multivariate analyses were performed by logistic regression. Internal validation of the model was performed using resampling techniques. RESULTS: The incidence of the outcome variable was 4.29% (95% CI 3.6-4.9). The variables remaining in the final logistic model were: age, sex, previous lung cancer resection, dyspnea (mMRC), right pneumonectomy, and ppo DLCO. The performance parameters of the model adjusted by resampling were: C-statistic 0.712 (95% CI 0.648-0.750), Brier score 0.042 and bootstrap shrinkage 0.854. CONCLUSIONS: The risk prediction model obtained from the GEVATS database is a simple, valid, and reliable model that is a useful tool for establishing the risk of a patient undergoing anatomic lung resection.

OBJECTIVES: Failure to rescue (FTR) is defined by the number of deaths among patients experiencing major complications after surgery. In this report we analyze FTR and apply a cumulative sum control chart (CUSUM) methodology for monitoring performance in a large series of operated lung carcinoma patients. METHODS: Prospectively stored records of cases undergoing anatomical lung resection in one center were reviewed. Postoperative adverse events were coded and included as a binary variable (major, or minor complications). The occurrence of 30-day mortality was also recorded. Patients dying after suffering major complications were considered as FTR. Risk-adjusted CUSUM graphs using EuroLung1 and 2 variables were constructed for major complications and FTR. Points of plateauing or trend inversion were checked to detect intentional or non-adverted changes in the process of care. RESULTS: 2237 cases included. 9.1% cases suffered major complications. The number of cases considered as failures to rescuing was 46 (2.1% of the total series and 22.5% of cases having major complications). The predictive performance of EuroLung1 and 2 models was as follows: EuroLung1 (major morbidity) C-index 0.70 (95%CI: 0.66-0.73); EuroLung2 (applied to FTR) C-index 0.81 (95%CI: 0.750.87). CUSUM graphs depicted improvement in rescuing complicated patients after case 330 but no improvement in the rate of non-complicated cases until case 720. CONCLUSIONS: FTR offers a complementary view to classical outcomes for quality assessment in Thoracic Surgery. Our study also shows how the analysis of FTR on time series can be applied to evaluate changes in team performance along time.

RESUMO
OBJECTIVES: The use of sealants is one of the methods available to reduce the occurrence of intraoperative air leaks. The objective of this modified Delphi survey among ESTS members is to understand the attitudes of clinicians to the optimal use of sealants in air leak management. METHODS: To understand the attitudes of a wider sample of clinicians, a questionnaire was developed highlighting key issues through 37 statements. Respondents were invited to score their level of agreement with each. A modified Delphi methodology was used to review responses with a threshold of agreement for consensus of 75%. RESULTS: A total of 258 responses were received (response rate 17%). Respondents agreed that prolonged air leaks are a common complication in thoracic surgery presenting a burden to the patient and increasing the costs of care. There is clear support for the use of sealants to reduce costs and improve the efficiency of healthcare provision and duration of chest tube use in selected high-risk patients with intraoperative air leak at the end of the lung surgery. Respondents also agreed that, due to often complex nature of thoracic surgery, sealants should be developed specifically for this application. CONCLUSION: There is a clear role for sealants in the management of air leaks and certain surgical procedures demand their use (i.e. lung volume reduction surgery, decortication). This opinion-based consensus review helps to raise the debate about the burden of air leaks in thoracic surgery in order that this issue is recognized in practice and informs the optimal use of sealants in lung surgery.

RESUMO
BACKGROUND: The Spanish Customized Adjuvant Therapy (SCAT) trial assessed the role of individualized adjuvant therapy in clinical N0 incidental pN1 and/or N2 non-small cell lung cancer (NSCLC) completely resected. We assessed surgical topics with an in-depth analysis of quality of lymphadenectomy based on International Association for the Study of Lung Cancer (IASLC) recommendations. METHODS: Patients with information about lymphadenectomy available were included (N=451). Prospectively collected data about tumor, type of resection, and postoperative morbidity and quality of lymph node dissection (LND) were retrospectively evaluated. Role of lymph node assessment on survival was analyzed using Kaplan-Meier curves, using regression models to identify prognostic factors. RESULTS: In 33.7%, 17.7% and 49.9% of cases, regions 7, 10 and 11 respectively were not assessed. In 21.1% of patients, less than three lymph node regions were biopsied, while in 19.6% of patients less than six lymph nodes were assessed. In 53,4% of patients only one N1 region was evaluated. From patients with positive N2, 8.9% had no N1 regions biopsied. Twenty-nine percent of patients with at least one N2 lymph node resected shown the highest region involved. Thirty-day postoperative mortality was unknown. Five-year overall survival (OS) was 61.7% (95% CI: 55.4-67.4%), 51.5% (95% CI: 39.2-62.4%) and 42.3% (95% CI: 32.1-52.2%) for patients with N1, N2 and N1+N2 disease, respectively (P<0.01). Both number of lymph nodes resected and number of lymph nodes involved by tumor were significantly related to prognosis. CONCLUSIONS: IASLC recommendations for surgical resections were not followed in a high proportion of surgical procedures. Hilar and mediastinal lymph node assessment and involvement showed to impact prognosis. Surgical issues such as postoperative mortality could not be evaluated owing to trial design.
RESUMO
Ambulatory treatment of pleural problems such as pneumothorax and malignant pleural effusions has been extensively described and is commonly used. On the contrary, outpatient management of chest tubes after lung resection is less frequently performed. Because prolonged air leak after lobectomy is a common problem, early discharge of these patients under pleural drainage can avoid many hospital days without compromising the quality of care. In this article, general rules for outpatient chest tube management are described and available portable devices are reviewed.

INTRODUCTION: Our study sought to know the current implementation of video-assisted thoracoscopic surgery (VATS) for anatomical lung resections in Spain. We present our initial results and describe the auditing systems developed by the Spanish VATS Group (GEVATS). METHODS: We conducted a prospective multicentre cohort study that included patients receiving anatomical lung resections between 12/20/2016 and 03/20/2018. The main quality controls consisted of determining the recruitment rate of each centre and the accuracy of the perioperative data collected based on six key variables. The implications of a low recruitment rate were analysed for "90-day mortality" and "Grade IIIb-V complications". RESULTS: The series was composed of 3533 cases (1917 VATS; 54.3%) across 33 departments. The centres' median recruitment rate was 99% (25-75th:76-100%), with an overall recruitment rate of 83% and a data accuracy of 98%. We were unable to demonstrate a significant association between the recruitment rate and the risk of morbidity/mortality, but a trend was found in the unadjusted analysis for those centres with recruitment rates lower than 80% (centres with 95-100% rates as reference): grade IIIb-V OR=0.61 (p=0.081), 90-day mortality OR=0.46 (p=0.051). CONCLUSIONS: More than half of the anatomical lung resections in Spain are performed via VATS. According to our results, the centre's recruitment rate and its potential implications due to selection bias, should deserve further attention by the main voluntary multicentre studies of our speciality. The high representativeness as well as the reliability of the GEVATS data constitute a fundamental point of departure for this nationwide cohort.

Tridimensional custom-made titanium-printed prosthesis have gained certain relevance as an alternative for chest wall reconstruction although different limitations such as uncomfortable intraoperative placement, long manufacturing time or high costs hinder its use when compared to other standard devices. Trying to overcome these problems, we developed a new model of customized modular titanium-printed prosthesis (CM-TPP) for chest wall reconstruction after breast metastasis resection that seems to offer some advantages over other custom-made reconstructive devices.
