RESUMO
Given the association between lymphadenectomy and survival after esophagectomy, and the ongoing development of effective adjuvant protocols for identified residual disease, we determined factors contributing to lymph node yield and effects on postoperative morbidity following esophagectomy by thoracic surgeons. Using the Society of Thoracic Surgeons General Thoracic Surgery Database, all patients who underwent esophagectomy for primary esophageal cancer with gastric conduit reconstruction from 2012 to 2016 were identified. Patient demographics, technical factors, and tumor characteristics associated with lymph node yield were determined using a multivariable multilevel mixed-effects regression model. Associations between lymph node yield and perioperative morbidity and mortality were similarly assessed. A total of 8480 patients were included. The median number of nodes harvested was 16 [Interquartile Range 11-22]. Factors associated with fewer nodes included female gender (b=-0.53, P=0.032), body mass index <18.5 (b=-1.46, P=0.012), prior cardiothoracic surgery (b=-0.73, P=0.015), intraoperative blood transfusion (b=-1.43, P<0.001), squamous cell histology (b=-0.86, P=0.006), and neoadjuvant treatment (b=-1.41, P<0.001). Operative approach significantly affected lymph node yield, with minimally invasive approaches demonstrating higher lymph node counts, and open transhiatal esophagectomy recovering the fewest nodes. Findings were independent of clinical center. There was no association of higher lymph node yield with 30-day mortality, with only slightly increased risk for chyle leak (odds ratio [OR] 1.02, P=0.012). In conclusion, several patient and tumor factors affect lymph node recovery with esophagectomy, independent of hospital center. Technical aspects, specifically minimally invasive approach, play a significant role in quantified lymph node yield. Higher operative lymph node yield was associated with minimal increased morbidity.

BACKGROUND: Esophageal perforation is a morbid condition and remains a therapeutic challenge. We report the outcomes of a large institutional experience with esophageal perforation and identify risk factors for morbidity and mortality. METHODS: A retrospective analysis was conducted on 142 patients who presented with a thoracic or gastroesophageal junction esophageal perforation from 1995 to 2020. Baseline characteristics, operative or interventional strategies, and outcomes were analyzed by etiology of the perforation and management approach. Multivariable cox and logistic regression models were constructed to identify predictors of mortality and morbidity. RESULTS: Overall, 109 (77%) patients underwent operative intervention, including 80 primary reinforced repairs and 21 esophagectomies and 33 (23%) underwent esophageal stenting. Stenting was more common in iatrogenic (27%) and malignant (64%) perforations. Patients who presented with a postemetic or iatrogenic perforation had similar 90-day mortality (16% and 16%) and composite morbidity (51% and 45%), whereas patients who presented with a malignant perforation had a 45% 90-day mortality and 45% composite morbidity. Risk factors for mortality included age >65 years (hazard ratio [HR] 1.89 [1.02-3.26], P = 0.044) and a malignant perforation (HR 4.80 [1.31-17.48], P = 0.017). Risk factors for composite morbidity included pleural contamination (odds ratio [OR] 2.06 [1.39-4.43], P = 0.046) and sepsis (OR 3.26 [1.44-7.36], P = 0.005). Of the 33 patients who underwent stent placement, 67% were successfully managed with stenting alone and 30% required stent repositioning. CONCLUSIONS: Risk factors for morbidity and mortality after esophageal perforation include advanced age, pleural contamination, septic physiology, and malignant perforation. Primary reinforced repair remains a reasonable strategy for patients with an esophageal perforation from a benign etiology.

OBJECTIVE: Bioengineering of viable, functional, and implantable human lung grafts on porcine matrix. SUMMARY BACKGROUND DATA: Implantable bioartificial organ grafts could revolutionize transplant surgery. To date, several milestones toward that goal have been achieved in rodent models. To make bioengineered organ grafts clinically relevant, scaling to human cells and graft size are the next steps. METHODS: We seeded porcine decellularized lung scaffolds with human airway epithelial progenitor cells derived from rejected donor lungs, and banked human umbilical vein endothelial cells. We subsequently enabled tissue formation in whole organ culture. The resulting grafts were then either analyzed in vitro (n = 15) or transplanted into porcine recipients in vivo (n = 3). RESULTS: By repopulating porcine extracellular matrix scaffolds with human endothelial cells, we generated pulmonary vasculature with mature endothelial lining and sufficient anti-thrombotic function to enable blood perfusion. By repopulating the epithelial surface with human epithelial progenitor cells, we created a living, functioning gas exchange graft. After surgical implantation, the bioengineered lung grafts were able to withstand physiological blood flow from the recipient's pulmonary circulation, and exchanged gases upon ventilation during the 1-hour observation. CONCLUSIONS: Engineering and transplantation of viable lung grafts based on decellularized porcine lung scaffolds and human endothelial and epithelial cells is technically feasible. Further graft maturation will be necessary to enable higher-level functions such as mucociliary clearance, and ventilation-perfusion matching.

PURPOSE: We investigated the metabolic response of lung cancer to radiotherapy or chemoradiotherapy by (18)F-FDG PET and its utility in guiding timely supplementary therapy. METHODS: Glucose metabolic rate (MRglc) was measured in primary lung cancers during the 3 weeks before, and 10-12 days (S2), 3 months (S3), 6 months (S4), and 12 months (S5) after radiotherapy or chemoradiotherapy. The association between the lowest residual MRglc representing the maximum metabolic response (MRglc-MMR) and tumor control probability (TCP) at 12 months was modeled using logistic regression. RESULTS: We accrued 106 patients, of whom 61 completed the serial (18)F-FDG PET scans. The median values of MRglc at S2, S3 and S4 determined using a simplified kinetic method (SKM) were, respectively, 0.05, 0.06 and 0.07 µmol/min/g for tumors with local control and 0.12, 0.16 and 0.19 µmol/min/g for tumors with local failure, and the maximum standard uptake values (SUVmax) were 1.16, 1.33 and 1.45 for tumors with local control and 2.74, 2.74 and 4.07 for tumors with local failure (p < 0.0001). MRglc-MMR was realized at S2 (MRglc-S2) and the values corresponding to TCP 95 %, 90 % and 50 % were 0.036, 0.050 and 0.134 µmol/min/g using the SKM and 0.70, 0.91 and 1.95 using SUVmax, respectively. Probability cut-off values were generated for a given level of MRglc-S2 based on its predicted TCP, sensitivity and specificity, and MRglc ≤0.071 µmol/min/g and SUVmax ≤1.45 were determined as the optimum cut-off values for predicted TCP 80 %, sensitivity 100 % and specificity 63 %. CONCLUSION: The cut-off values (MRglc ≤0.071 µmol/min/g using the SKM and SUVmax ≤1.45) need to be tested for their utility in identifying patients with a high risk of residual cancer after standard dose radiotherapy or chemoradiotherapy and in guiding a timely supplementary dose of radiation or other means of salvage therapy.

BACKGROUND: We describe use, patients, and outcome of diagnostic lobectomy for suspected lung cancer without pathologic confirmation. METHODS: A retrospective review of consecutive lobectomy or bilobectomy for suspected or confirmed primary pulmonary malignancy was conducted using our participant's sample of The Society of Thoracic Surgeons database. Surgeons performed lobectomy based on clinical diagnosis or confirmation on a biopsy specimen. Lung cancer confirmed by biopsy specimen was compared with cases clinically suspected. Univariate and multivariate analyses identified variables associated with lobectomy without biopsy specimen confirmation. RESULTS: Among 2651 lobectomies performed between 2006 and 2019 in 2617 patients, lung cancer was confirmed by preoperative biopsy specimen in 51.6% (1368 of 2651) or was clinically suspected before the operation in 48.4% (1283 of 2651). The intraoperative biopsy specimen in 585 of 1283 cases (45.6%) proved lung cancer before lobectomy, whereas lobectomy proceeded in 698 cases (54.4%) without a diagnosis. Final pathology proved lung cancer in 90% (628 of 698) without a diagnosis before lobectomy and nonmalignant disease in 10% (70 of 698). Nonneoplastic pathology included granulomas (30 of 70 [43%]), pneumonia (12 of 70 [17%]), bronchiectasis (7 of 70 [10%]), and other lesions (21 of 70 [30%]). Operative mortality was 0.94% (25 of 2651) for the cohort and 1.0% (7 of 698) for diagnostic lobectomy only. Multivariate analysis identified patient age, type of lobectomy (right middle lobe), and the intermediate study tercile as associated with diagnostic lobectomy. CONCLUSIONS: Lobectomy for suspected lung cancer without diagnosis is common, represents practice variation, and infrequently (10% diagnostic, 2.6% all lobectomies) removes nonmalignant disease. Tissue confirmation before lobectomy is preferred, particularly when operative risk is increased. Diagnostic lobectomy is acceptable in carefully selected patients and lesions.

BACKGROUND: We sought to determine the rate and risk factors of recurrent spontaneous pneumothorax in a diverse population. METHODS: Cohort study using the California Public Discharge Data file (1995-2010). We identified patients with first-time spontaneous pneumothorax. The primary outcome was recurrent pneumothorax. Associations with clinical, patient, and hospital characteristics were assessed using Cox regression analysis. RESULTS: Among 14,609 patients with a first-time episode of spontaneous pneumothorax, 26.2% developed a recurrence. Risk factors included age <35 (Hazard Ratio [HR] 1.24 95%-Confidence Interval [CI] 1.14-1.36), Asian race (HR 1.24, CI 1.13-1.37), and tube thoracostomy (HR 1.2, CI 1.15-1.31). Mechancial pleurodesis (HR 0.37 CI 0.31-0.45) was superior to chemical pleurodesis (HR 0.71 CI 0.58-0.86) in reducing recurrence risk. CONCLUSIONS: The risk of recurrent pneumothorax is greatest in patients age <35, Asians, and those requiring a tube thoracostomy. The risks of operative intervention should be balanced against patient risk for recurrence.

BACKGROUND: Airway release (AR) maneuvers performed during airway resection to reduce anastomotic tension have not been thoroughly studied. METHODS: This study retrospectively analyzed consecutive resections for postintubation stenosis (PITS) and primary tracheal neoplasms (PTNs) at Massachusetts General Hospital (Boston, MA). Anastomotic complications were defined as stenosis, separation, necrosis, granulation tissue, and air leak. Logistic regression modeling was used to identify factors associated with AR and adverse outcome. RESULTS: From 1993 to 2019, 545 patients with PITS (375; 68.8%) and PTNs (170; 31.2%) underwent laryngotracheal, tracheal, or carinal (resections and reconstructions; 5.7% (31 of 545) were reoperations. AR was performed in 11% (60 of 545): in 3.8% of laryngotracheal resections (6 of 157; all laryngeal), in 9.8% of tracheal resections (34 of 347; laryngeal, 12, and hilar, 22), and in 49% of carinal resections (20 of 41; laryngeal, 1, and hilar, 19). Mean resected length was 3.5 cm (range, 1to- 6.3 cm) with AR and 3.0 cm (range, 0.8 to 6.5 cm) without AR (P < .01). Operative mortality was 0.7% (4 of 545); all 4 anastomoses were intact until death. Anastomotic complications were present in 5% of patients who underwent AR (3 of 60) and in 9.3% (45 of 485) of patients who did not. AR was associated with resection length of 4 cm or longer (odds ratio [OR], 6.15; 95% confidence interval [CI], 1.37 to 27.65), PTNs (OR, 7.81; 95% CI, 3.31 to 18.40), younger age (OR, 0.96; 95% CI, 0.94 to 0.98), and lung resection (OR, 6.09; 95% CI, 1.33 to 27.90). Anastomotic complications in patients with tracheal anastomoses were associated with preexisting tracheostomy (OR, 2.68; 95% CI, 1.50 to 4.80), but not release. CONCLUSIONS: Tracheal reconstruction succeeds, even when anastomotic tension requires AR. Because intraoperative assessment may underestimate tension, lowering the threshold for AR seems prudent, particularly in patients with diabetes.

Air leaks and residual airspaces following lung resection are common problems in thoracic surgery. Prolonged air leaks frequently necessitate extended hospitalization. This is true whether the surgery was done in an open fashion or with video-/robot-assisted thoracic surgery. In this review, the authors present common risk factors that predispose to prolonged air leaks and discuss the management options for air leaks by focusing on intraoperative maneuvers, postoperative considerations, and options for difficult-to-manage air leaks and spaces. They also discuss options to prevent such spaces and present management approaches to take care of patients with these challenging problems.

OBJECTIVES: Idiopathic laryngotracheal stenosis (ILTS) is an uncommon problem arising mostly in women. In some, it arises during or is exacerbated by pregnancy. Experience with management of patients with this rare association is limited. This study seeks to evaluate the management of patients with pregnancy-associated ILTS and compare outcomes to cases not associated with pregnancy. METHODS: Retrospective review of 15 patients undergoing surgical treatment of pregnancy-associated ILTS from 1971 to 2013. Variables of interest and airway outcomes were compared to patients with non-pregnancy-associated ILTS. RESULTS: Pregnancy-associated ILTS was observed in 15/263 (5.7%) patients. Symptoms developed during their first pregnancy. When compared to non-pregnancy patients, these patients were younger (37 vs 47 years; P = 0.0003), had more prior tracheostomies (26.7% vs 10.9%; P = 0.085) and had more preoperative airway dilatations (86.7% vs 57.7%; P = 0.030). All patients completed pregnancy without complications and ultimately underwent laryngotracheal resection. The expression of hormonal receptors in the surgical specimens was similar in both groups (oestrogen receptors: 100% vs 75% and progesterone receptors: 71.4% vs 72.1%, in pregnancy and non-pregnancy patients, respectively). Airway outcomes were good/excellent in 13 (86.7%) patients with pregnancy-associated ILTS and 225 (90.7%) patients without pregnancy association (P = 0.642), and did not change when adjusting for other risk factors. CONCLUSIONS: Pregnancy-associated ILTS is rare. The pathophysiology is unclear, but appearance of symptoms during pregnancy may suggest hormonal factors. To minimize foetal risk, dilatation during pregnancy followed by laryngotracheal resection after delivery is the preferred treatment. Pregnancy association does not seem to affect outcomes with expected satisfactory results in most patients.

OBJECTIVES: Gastric emptying delay after oesophagectomy may occur in conduits exposed to pleural forces of respiration or anatomic obstruction. Remedial operations addressing both causes are rarely reported. The study aim was to categorize severe gastric conduit obstruction (GCO) and report the outcome of surgical revision. METHODS: A single-institution, retrospective study of gastric conduit revision following oesophagectomy for oesophageal cancer investigated incidence, risk factors and categories of conduit obstruction. Evaluation consisted of contrast studies, computed tomogram and endoscopy. Interventions were categorized according to obstructive cause and included pyloroplasty, hiatal hernia reduction and thoraco-abdominal conduit repositioning. RESULTS: Among 1246 oesophagectomies over a 17-year period, 14 patients (1.1%) required post-oesophagectomy relief of GCO. Two additional patients presented after oesophagectomy elsewhere. Before oesophagectomy, 18.8% (3/16) and 62.5% (10/16) of patients were on chronic opioid and psychotropic medications, respectively. Distinct anatomic features separated obstruction into 3 categories: pyloric in 31% (5/16), extrinsic in 12.5% (2/16) and combined in 56.3% (9/16). Operative revision led to complete symptom resolution in 50% (8/16) of patients and symptom improvement in 43.8% (7/16) of patients. One patient (1/16, 6.25%) in the combined obstruction group did not improve with surgical revision. CONCLUSIONS: GCO after oesophagectomy rarely requires surgical revision. Potential association with medications affecting oesophageal and gastric motility requires further investigation. Classification of obstruction identifies a patient subset with lower success after surgical revision.

BACKGROUND: Approximately 10% to 15% of patients with solitary fibrous tumors of the pleura (SFTP) have recurrence after resection. Many are not candidates for reresection and lack effective treatments. We explored the expression of programmed death ligand 1 (PD-L1) as a biomarker for candidacy for treatment with immune checkpoint inhibitors. METHODS: We reviewed the medical records of 52 patients with primary SFTP and 5 with recurrent SFTP. We performed immunohistochemistry on tumor tissue to determine the expression of PD-L1 and infiltration by cluster of differentiation 8 (CD8)-positive immune cells. RESULTS: Any PD-L1 expression was observed in 11 primary SFTP (21.2%). Overall, PD-L1 expression level was less than 1% in 10 patients (19.2%) and greater than 1% in 1 (1.9%). Tumor infiltration by CD8-positive immune cells was absent or rare in 13 patients (25%), less than 5% in 31 (59.6%), and 5% to 25% in 8 (15.4%). There were no associations between PD-L1 expression or immune cell infiltrates and known risk factors for recurrence or a prognostic risk score classification. Time to recurrence was strongly associated with the risk score classification (P < .001), but it was not associated with PD-L1 expression (P = .296) or immune cell infiltrates (P = .619). In recurrent SFTP, PD-L1 was expressed in 4 of 10 tumors (40%; all <1% expression). There was no correlation in PD-L1 expression between primary and recurrent SFTP samples. CONCLUSIONS: A small subset of SFTP express PD-L1 at low levels (<1%) but exhibit colocalization of CD8-positive immune cells suggesting an inducible expression mechanism. The role of PD-L1 merits exploration in the clinical setting in patients with advanced SFTP when alternative treatments or clinical trials are considered.

OBJECTIVES: Failure of anastomotic healing is a morbid complication after airway or oesophageal surgery. Hyperbaric oxygen therapy (HBOT) has been used extensively in the management of complex wound-healing problems. We demonstrate the use of HBOT to rescue at-risk anastomoses or manage anastomotic failures in thoracic surgery. METHODS: Retrospective review of 25 patients who received HBOT as part of the management of tracheal or oesophageal anastomotic problems during 2007-2018. HBOT was delivered at 2 atm with 100% oxygen in 90-min sessions. RESULTS: Twenty-three patients underwent airway resection and reconstruction while 2 patients underwent oesophagectomy. There were 16 (70%) laryngotracheal and 7 (30%) tracheal resections. Necrosis at the airway anastomosis was found in 13 (57%) patients, partial dehiscence in 2 (9%) patients and both in 6 (26%) patients. HBOT was prophylactic in 2 (9%) patients. Patients received a median of 9.5 HBOT sessions (interquartile range 5-19 sessions) over a median course of 8 days. The airway anastomosis healed in 20 of 23 (87%) patients. Overall, a satisfactory long-term airway outcome was achieved in 19 (83%) patients; 4 patients failed and required reoperation (2 tracheostomies and 1 T-tube). HBOT was used in 2 patients after oesophagectomy to manage focal necrosis or ischaemia at the anastomosis, with success in 1 patient. Complications from HBOT were infrequent and mild (e.g. ear discomfort). CONCLUSIONS: HBOT should be considered as an adjunct in the management of anastomotic problems after airway surgery. It may also play a role after oesophagectomy. Possible mechanisms of action are rapid granulation, early re-epithelialization and angiogenesis.

OBJECTIVE: Pulmonary nodules found incidentally or by lung cancer screening differ in prevalence, risk profile, and diagnostic intervention. The results of surgical intervention for incidental versus screening lung nodules during multidisciplinary Pulmonary Nodule and Lung Cancer Screening Clinic (PNLCSC) follow-up have not been reported. METHODS: All patients evaluated at a PNLCSC from 2012 to 2018 following referral by primary care physicians, specialist physicians, or self-referral after computed tomography (CT) identified nodules on routine diagnostic CT (incidental group) or lung cancer screening CT (screening group) were included. Follow-up interval, invasive intervention, histology, postoperative events, survival, and recurrence were compared. RESULTS: Of 747 patients evaluated in the PNLCSC, 129 (17.2%) underwent surgical intervention. The surgical cohort consisted of 104 (80.6%) incidental and 25 (19.3%) screening patients followed over a mean of 122 and 70 days, respectively. More benign lesions were excised in the incidental group (20.2%, 21/104)-representing 3.3% (21/632) of all incidental nodules evaluated-than in the screening group (4%, 1/25) (P = .038). Operative mortality was zero. Among 99 patients with primary lung cancer, 87% (screening) and 86.8% (incidental) were pathologic stage Ia. Complete follow-up was available in 725 of 747 (97%), and no patient developed progressive disease. Disease-free survival at 5 years was 74.9% (incidental) and 89.3% (screening) (P = .48). CONCLUSIONS: A unique multidisciplinary PNLCSC for incidental and lung cancer screening-detected nodules with individualized risk assessment reliably identifies primary and metastatic tumors while exposing few patients to diagnostic excision for benign disease. Longer-term outcomes, strategies to limit radiation exposure, and cost control need further study.

INTRODUCTION: The clinical impact of a positive radial margin after esophagectomy for cancer has not been clearly identified. The goal of this study was to identify risk factors for a positive radial margin and determine the impact on recurrence and survival. METHODS: Retrospective review of 196 patients with pathological T3 N0-3 esophageal adenocarcinoma undergoing esophagectomy between 2002 and 2017. Mortality data was extracted from Electronic Medical Records and Social Security Death Index. RESULTS: Mean age was 63.7 ± 11.4 years, and there were 166 (84.7%) men. Neoadjuvant therapy was given in 141(71.9%) patients. We identified 29(14.8%) patients with a positive radial margin. Factors significantly associated with a positive radial margin include not receiving neoadjuvant therapy and presence of lymphatic, vascular, or perineural invasion. Overall, there were 94(48%) recurrences during a mean follow-up of 24.7 months. Involvement of the radial margin was not significantly associated with recurrence-free survival (HR 1.24, CI 95% 0.73-2.12, p = 0.425). Overall survival for the entire cohort was 41.6% and 28.9% at 3 and 5 years, respectively. Involvement of the radial margin did not have a significant impact on overall survival (HR 1.23, CI 95% 0.68-2.22, p = 0.493). CONCLUSIONS: The likelihood of encountering a positive margin is associated with lack of neoadjuvant treatment and the presence of lymphatic, vascular, or perineural invasion in the esophagectomy specimen. An involved radial margin after esophagectomy for locally advanced cancer was not associated with tumor recurrence or overall survival in our cohort, and other factors such as lymph node involvement are stronger in determining outcome.

Resident education in the operating room and surgical resident autonomy represent two enormous challenges within cardiothoracic (CT) training programs. The goal of surgical educators and CT trainees is to ensure the graduating resident's ability to safely operate independently at the completion of training. The field has come a long way from the notion of see one, do one, teach one, which was once the norm. Cardiothoracic surgery continues to become more specialized and the patients more complex with greater scrutiny of outcomes. There are many challenges that are faced in contemporary CT training to make intraoperative teaching harder than ever.

OBJECTIVES: Complete resection of neoplasms involving the carina are technically challenging and have high operative morbidity and mortality. This study examines the last 2 decades of clinical experience at our institution. METHODS: Medical records were retrospectively reviewed between 1997 and 2017 to identify all patients who underwent carinal resection. Primary outcome measures include risk factors for complications and overall survival. RESULTS: In total, 45 carinal resections were performed with a median follow-up of 3.4 years (interquartile range 0.8-8.5). Procedures included 21 neocarinal reconstructions (48%), 14 right carinal pneumonectomies (30%), 9 left carinal pneumonectomies (20%), and 1 carinal plus lobar resection (2%). Age ranged from 27 to 74 years, and 23 of 45 patients were female. Eight received neoadjuvant chemotherapy and 6 preoperative radiation. Extracorporeal membrane oxygenation and cardiopulmonary bypass were intraoperatively used for 4 patients with no mortality. Four patients underwent superior vena cava resection and reconstruction. Anastomotic complications occurred in 5 patients, all of which were managed conservatively: 1 required stent placement and a second underwent hyperbaric oxygen therapy. Postoperative events were observed in 26 patients (58%), including pneumonia (n = 11), blood transfusion (n = 8), and atrial arrhythmias (n = 8). More serious complications, such as acute respiratory distress syndrome, occurred in 3 patients. Postoperative events were most closely associated with pulmonary resection (P = .040). There were 3 deaths, yielding an overall operative 30- and 90-day mortality of 6.8% and 7%, respectively. CONCLUSIONS: Despite advances in perioperative management, carinal resection poses challenges for both patient and surgeon. Preoperative chemotherapy, radiation, and concomitant pulmonary resection were associated with increased risk of complications. Patient selection and meticulous surgical technique contribute to reduction in morbidity and mortality.

Despite an ever-diversifying United States population, women and underrepresented minorities lack proportionate membership in the cardiothoracic surgery workforce. Many Society of Thoracic Surgeons (STS) members view achieving a diverse cardiothoracic surgery workforce as important. To address the needs of our specialty to better reflect and understand (cultural competence) our evolving communities, the STS created the Workforce on Diversity and Inclusion. The Workforce's mission is to cultivate an environment of inclusion and diversity within the STS as well as the cardiothoracic surgical specialty. This report will discuss the background for the creation of the Workforce on Diversity and Inclusion, describe the "return on investment" in diversity, the current state of diversity in surgery, illustrate STS members' views on the importance of a diverse specialty, and present current and future activities of the Workforce on Diversity and Inclusion.

BACKGROUND: To evaluate the management, complications of treatment, and outcomes of postintubation tracheal stenosis. METHODS: A retrospective review was performed of records from a prospective database of all patients undergoing tracheal or laryngotracheal resection from 1993 to 2017 for postintubation tracheal stenosis. Redo operations after failure of initial resection and reconstruction for postintubation tracheal stenosis were included. RESULTS: There were 392 patients whose ages ranged from 3 months to more than 84 years. A tracheostomy was performed in 275 as part of their care before surgery (present at time of resection in 123), dilations in 201, laser treatment in 82, T tubes in 66, and stents in 44 patients. Median length of resection was 3 cm. Laryngeal release was required in 15 of 392 (3.8%). Operative mortality was 0.8% (3 of 392); T tubes, tracheostomy present at resection, requirement for postoperative tracheostomy, and laryngeal involvement adversely impacted outcomes. Patients having tracheal resection and reconstruction had good or satisfactory outcomes in 96% (289 of 301) compared with 85% (77 of 91) having laryngotracheal resection. Complications within 30 days and at more than 30 days occurred in 116 patients and 14 patients, respectively. There were 96 anastomotic complications-68% minor (65 of 96), and 32% major (31 of 96). Necrosis of cartilage occurred in 12 patients and dehiscence in 14 patients. CONCLUSIONS: Despite advances in care postintubation tracheal stenosis remains a challenging problem. Laryngotracheal resection and tracheostomy lead to worse outcomes. Excellent surgical results can be obtained for postintubation tracheal stenosis. Good results require careful evaluation, management of comorbid conditions, meticulous technique, minimizing tension, and preservation of blood supply.

OBJECTIVES: Many patients with primary malignant tracheal neoplasms are not surgical candidates nor do they experience residual or recurrent disease after surgery and may benefit from alternative therapies. This study explores the expression of programmed death ligand 1 (PD-L1) in patients with primary tracheal malignancy as a biomarker for candidacy for treatment with immune checkpoint inhibitors. METHODS: We conducted a retrospective review of the medical records of 23 patients with resected primary tracheal malignant tumours from 2010 to 2016. Paraffin-embedded blocks of tumour tissue were evaluated immunohistochemically to determine the expression of PD-L1 and infiltration by CD8+ immune cells. RESULTS: We identified 14 (61%) adenoid cystic carcinomas, 4 (17%) squamous cell carcinomas (SCC), 4 (17%) mucoepidermoid carcinomas and 1 adenosquamous carcinoma. PD-L1 expression was observed in 3 (75%) cases of SCC and 1 (100%) case of adenosquamous carcinoma, but it was absent in cases of adenoid cystic carcinomas and mucoepidermoid carcinomas. PD-L1 expression was significantly higher in tumours with a SCC component than in salivary-type tumours (P = 0.001). The presence of CD8+ immune cells in the tumour or peritumoural stroma was significantly higher in cases of tracheal tumours with a SCC component than in salivary-type tumours. CONCLUSIONS: Salivary-type primary malignant tracheal tumours do not significantly express PD-L1. In contrast, most primary tracheal tumours with a SCC component show membranous expression of PD-L1 and larger numbers of infiltrating CD8+ immune cells. PD-L1 expression may serve as a biomarker in patients with primary tracheal squamous cell malignant neoplasms when the patients are being considered for alternative treatments and inclusion in clinical trials.
