RESUMO
OBJECTIVE: To assess management strategies for pediatric patients with the challenging combination of congenital heart diseases (CHDs) and airway anomalies. STUDY DESIGN: Patients diagnosed with CHD and airway anomalies in the Pediatric Cardiac Surgery Centre of Fuwai Hospital from January 2016 to December 2020 were included in this retrospective study. Patients were divided into three groups based on different management, including the conservative group, the slide group (slide tracheoplasty), and the suspension group (suspension with external stenting). Patients' data and computed tomography measurements from medical records were reviewed. RESULTS: A total of 139 patients were included in the cohort; 107 had conservative airway treatment (conservative group), 15 had slide tracheoplasty (slide group), and 17 had tracheal suspension operation (suspension group). The top three associated intracardiac anomalies were ventricular septal defect (n = 34, 24%), pulmonary artery sling (n = 22, 16%), and tetralogy of Fallot (n = 15, 11%). Compared with patients with conservative airway management (100 minutes [median], 62-152 [IQR]), the extra airway procedure prolonged cardiopulmonary bypass duration, with 202 minutes (IQR, 119-220) for the slide group and 150 minutes (IQR, 125-161) for the suspension group. Patients who underwent slide tracheoplasty required prolonged mechanical ventilation (129 minutes [median], 56-328 [IQR]). Of the total cohort, 6 in-hospital deaths, all in the conservative group, and 8 mid-to long-term deaths, with 6 in the conservative group, occurred. CONCLUSIONS: Both conservative and surgical management of CHD patients with airway anomalies have promising outcomes. Extra tracheobronchial procedures, especially the slide tracheoplasty, significantly prolonged cardiopulmonary bypass duration. Based on multidisciplinary team assessment, individualized management strategies should be developed for these patients.

BACKGROUND: Patients with long-segment airway stenosis not amenable to conventional surgery may benefit from tracheal transplantation. However, this procedure has been only anecdotally reported, and its indications, techniques, and outcomes have not been extensively reviewed. METHODS: We conducted a systematic Literature search to identify all original articles reporting attempts at tracheal transplantation in humans. RESULTS: Of 699 articles found by the initial search, 11 were included in the systematic review, describing 14 cases of tracheal transplantation. Patients underwent transplantation for benign stenosis in nine cases, and for malignancies in five cases. In 12 cases blood supply to the trachea was provided by wrapping the graft in a vascularized recipient's tissue, while in 2 cases the trachea was directly transplanted as a vascularized composite allograft. The transplantation procedure was aborted before orthotopic transplantation in two patients. Among the remaining 12 patients, there was 1 operative mortality, while 4 patients experienced complications. Immunosuppressants drugs were administered to the majority of patients postoperatively, and only one group of authors attempted their withdrawal, in five patients. At the end of follow-up, all 11 patients surviving the operation were alive, but 2 had a recurrent tracheal stenosis requiring an airway appliance for breathing. CONCLUSION: Human tracheal transplantation is still at an embryonic phase. Studies available in the Literature report different surgical techniques, and information on long-term outcomes is still limited. Future research is needed in order to understand the clinical value of this procedure.

INTRODUCTION: Benign airway stenosis (BAS) is a severe pathologic condition. Complex stenosis has a high recurrence rate and requires repeated bronchoscopic interventions for achieving optimal control, leading to recurrent BAS (RBAS) due to intraluminal granulation. METHODS: This study explored the potential of autologous regenerative factor (ARF) for treating RBAS using a post-intubation tracheal stenosis canine model. Bronchoscopic follow-ups were conducted, and RNA-seq analysis of airway tissue was performed. A clinical study was also initiated involving 17 patients with recurrent airway stenosis. RESULTS: In the animal model, ARF demonstrated significant effectiveness in preventing further collapse of the injured airway, maintaining airway patency and promoting tissue regeneration. RNA-seq results showed differential gene expression, signifying alterations in cellular components and signaling pathways. The clinical study found that ARF treatment was well-tolerated by patients with no severe adverse events requiring hospitalization. ARF treatment yielded a high response rate, especially for post-intubation tracheal stenosis and idiopathic tracheal stenosis patients. CONCLUSION: The study concludes that ARF presents a promising, effective, and less-invasive method for treating RBAS. ARF has shown potential in prolonging the intermittent period and reducing treatment failure in patients with recurrent tracheal stenosis by facilitating tracheal mucosal wound repair and ameliorating tracheal fibrosis. This novel approach could significantly impact future clinical applications.

BACKGROUND: A straight silicone stent can be used to treat proximal benign tracheal stenosis in non-surgical candidates. However, stent migration is a common complication when placed at a particular location and can lead to major complications. This case series of laryngotracheal stenosis reports a fixation method for straight silicone stents in the subglottic trachea (Stage 3 of the McCaffrey classification). METHODS: The medical charts of these patients scheduled for straight silicone stent placement with suture fixation between 2014 and 2020 at the CHU UCL Namur Hospital (Belgium) were retrospectively reviewed. The procedure was performed using a rigid bronchoscope. Details of the procedure were obtained from medical records. RESULTS: This case series included six patients (males: 4, females: 2). The median patient age was 59 years. Two suture fixations were placed following previous silicone stent migration episodes, whereas the others were placed proactively to avoid this risk. All fixations were performed by the device Freka® Pexact II ENFIt®, originally developed for gastropexy in endoscopic gastrostomy. The sutures were subcutaneously buried. CONCLUSIONS: During the 6-month follow-up period, complications such as fixation issues and stent migration were reported despite the off-label use of the treatment. The straight silicone stent fixation technique used in this case series was simple and effective for securing the stent in upper benign tracheal stenosis.

BACKGROUND: Biodegradable (BD) stents made from polydioxanone have been used only in human airways. These stents combine the advantages of classical tracheal stents, and fewer side effects are expected due to their biocompatibility and their time-limited presence in airways. However, new clinical consequences have arisen. Here, the authors share their experiences with BD stents for tracheal indications, focusing on their safety and efficacy. METHODS: This was a retrospective review of a collected database of adult patients who underwent implantation of biodegradable tracheal stents between September 2013 and December 2022 at the Department of Respiratory Medicine of the 1st Faculty of Medicine in Prague and Thomayer University Hospital. The indications included functionally significant nonmalignant tracheal stenosis and tracheomalacia. Self-expandable, biodegradable, polydioxanone tracheal stents manufactured by ELLA-CS Ltd. (Hradec Kralove, Czech Republic) were implanted during rigid bronchoscopy under general anaesthesia. All patients were followed up in the department and were provided with the necessary care. The main efficacy and safety parameters and relationships were analysed using descriptive statistics and Fisher´s exact, Wilcoxon and KruskalâWallis tests. RESULTS: A total of 65 stents were implanted in 47 adult patients. During the first two months after implantation, when adequate function was expected, the stent was found to be effective in 26 out of 39 patients who completed this period (66.7%). The clinical effectiveness reached 89.7%, as early restenoses were mostly mild and necessitated treatment in only 4 patients. The frequencies of significant mucostasis, migration and granulation tissue growth were 2.6%, 7.5% and 23.1%, respectively, during this period. Thirty-four participants completed the half-year follow-up period after the first or second stent insertion, and some were followed up beyond this period. Poor control of symptoms, the development of restenosis and the need for interventions were characteristic of this period as the stents degraded. Twenty-two patients who experienced remodelling or stabilization of the tracheal lumen achieved a stent-free state. Seven patients underwent subsequent surgical treatment. CONCLUSIONS: BD stents are safe and provide adequate tracheal support until they begin to degrade. The use of BD stents necessitates close monitoring of patients and accurate treatment of possible restenosis. TRIAL REGISTRATION: Based on project NT14146 - Biodegradable stents in the management of the large airways (2013-2015, MZ0/NT), registered on May 1, 2013, in the Research and Development and Innovation Information System of the Czech Republic and at ClinicalTrials.gov (reg. no. NCT02620319, December 2, 2015).

BACKGROUND: Long-segment, grade IV suprastomal tracheal stenosis is rare and difficult to treat (Carpenter et al., 2022 [1]). Patients with grade IV stenosis have significant quality of life impairments since they are tracheostomy dependent and aphonic. Open airway surgery is often needed to improve tracheal patency, restore the patient's voice, and progress towards decannulation (Abouyared et al., 2017 [2]). However, not all patients are candidates for upfront open surgery (Abouyared et al., 2017; Shamji, 2018 [2,3]). Therefore, it is important to develop and refine endoscopic interventions to improve quality of life for these patients. METHODS: We describe a step-by-step endoscopic approach to the recannulation of long-segment, grade IV suprastomal tracheal stenosis. Briefly, our approach utilizes dual (proximal & distal) visualization of the stenosis prior to passing a 25 gauge needle through the stenosis to identify the proper trajectory for recannulation. Then a 16 gauge needle is passed in the same manner, and a wire is placed through the needle and into the distal airway. Once the airway is recannulated, the initial pinpoint opening is gradually widened in Seldinger fashion over the wire with Savary dilators followed by balloon dilation. Finally, a suprastomal L-stent (modified Montgomery T-Tube) is placed to reduce the risk of restenosis (Edwards et al., 2023 [4]). CASE DISCUSSION: A 39-year-old woman with a past medical history significant for poorly controlled type I diabetes mellitus and polysubstance abuse presented with tracheostomy dependence and aphonia. She was diagnosed with a long-segment, grade IV suprastomal tracheal stenosis and initially underwent endoscopic recannulation. This intervention restored her voice and allowed for optimization of her medical conditions before open airway surgery. CONCLUSION: Most patients experience a significant improvement in their quality of life as their voice is typically restored following this procedure. Additionally, individuals who eventually require open airway surgery gain additional time for medical optimization. In our experience, this procedure represents a safe and effective means of extending the utility of traditional endoscopic airway interventions for the management of patients with grade IV stenosis.

INTRODUCTION: Subglottic and tracheal stenosis (SGTS) in adults is an acquired or idiopathic condition that can lead to dyspnea, and even life-threatening airway obstruction. Endoscopic techniques have advanced and largely eclipsed open surgery, with open surgery now reserved for refractory cases (Hseu et al., 2013; Feinstein et al., 2017). Currently, there is no accepted guideline for the endoscopic treatment of SGTS. Thus, the aim of the present study is to examine the impact of various clinical and pathological characteristics on outcomes to endoscopic treatment in a cohort of SGTS patients. DISCLOSURE: None of the authors have any financial or personal relationship that could cause a conflict of interest regarding this article. METHODS: Retrospective chart review was performed for 41 patients presenting with SGS without a tracheostomy over a 4-year-period (2018-2022), within a single tertiary care center. Quantitative outcomes including number of dilation procedures undergone and need for open procedures were examined. The qualitative variables included a history of pulmonary disease, prior tracheostomy/tracheal resection, presence of tracheomalacia, granulation tissue, excessive dynamic airway collapse (EDAC), and etiology of idiopathic subglottic stenosis. RESULTS: The presence of granulation tissue seen on tracheoscopy was associated with a higher number (4+) of dilation procedures (p = 0.01). A history of pulmonary disease (p = 0.037), the presence of tracheomalacia (p = 0.039), and the presence of granulation tissue (0.003) were all associated with a need for open procedures. CONCLUSION: Patients with the presence of granulation tissue, tracheomalacia, and a history of pulmonary disease were more associated with more severe disease requiring either a higher number of endoscopic procedures or need for open procedures.

OBJECTIVES: To demonstrate varying degrees of immediate postoperative figure of 8 deformity following three different methods of tracheal suturing. STUDY DESIGN: Comparative ex-vivo study. METHODS: A fresh, unfixed rabbit trachea was harvested and bisected at its midpoint. The posterior membranous trachea was excised from both segments to mimic the anatomy of complete tracheal rings following longitudinal release. A slide tracheoplasty was performed on the same tracheal segments as an internal control, using three different methods of closure: simple running, running horizontal mattress, and a modified baseball stitch. Endoscopic and external photographs were taken immediately following repair to document the effect of closure technique on external and endoluminal anatomy. RESULTS: A simple running closure, in which traveling occurs between needle passes, showed the greatest degree of postoperative figure of 8 deformity. A running horizontal mattress suture closure showed less deformity and a modified running closure, in which traveling occurs within needle passes, showed the least deformity. CONCLUSIONS: Our study suggests that a minor modification of standard running closure techniques may help limit the common figure-of-8 deformity often noted following slide tracheoplasty. LAY SUMMARY: Figure of-8 deformity is a problem that can occur when repairing a narrow trachea referred to as tracheal stenosis. This deformity may be prevented using particular suture techniques which may decrease the likelihood that the trachea becomes blocked again following repair.

BACKGROUND: Expiratory central airway collapse (ECAC) following postintubation airway stenosis (PITS) is a rare phenomenon. The impact of airway malacia and collapse on the prognosis and the success rate of bronchoscopic interventional therapy in patients with PITS had been inadequately investigated. OBJECTIVE: The aim of this research was to assess the influence of airway malacia and collapse on the efficacy of bronchoscopic interventional therapy in patients with PITS. DESIGN: This retrospective analysis examined the medical documentation of individuals diagnosed with PITS who underwent bronchoscopic intervention at the tertiary interventional pulmonology center of Emergency General Hospital from 2014 to 2021. MAIN OUTCOME MEASURES: Data pertaining to preoperative, perioperative, and postoperative stages were documented and subjected to analysis. RESULTS: The patients in malacia and collapse group (MC group) exhibited a higher frequency of perioperative complications, including intraoperative hypoxemia, need for reoperation within 24 h, and postoperative intensive care unit admission rate (P < 0.05, respectively). Meanwhile, patients in group MC demonstrated significantly worse postoperative scores (higher mMRC score and lower KPS score) compared to those in pure stenosis group (P < 0.05, respectively), along with higher degrees of stenosis after treatment and a lower success rate of bronchoscopic intervention therapy cured (P < 0.05, respectively). Pearson analysis results showed that these terms were all significantly correlated with the occurrence of airway malacia and collapse in the airway (P < 0.05, respectively). CONCLUSION: The presence of malacia or collapse in patients with PITS was associated with increased perioperative complications following bronchoscopic interventional therapy, and significantly reduced the long-term cure rate compared to patients with pure tracheal stenosis.

INTRODUCTION: This study reports our experience with open reconstructive surgery in patients with laryngotracheal stenosis (LTS) following prolonged intubation and/or tracheostomy in the context of COVID-19. METHODS: All patients underwent a preoperative endoscopic airway assessment. Posterior glottic lesions were graded according to the Bogdasarian classification, subglottic-tracheal lesions according to the Cotton-Myers classification and postoperative complications reported by the Clavien-Dindo classification. We report postoperative outcomes and functional results in this patient subset. RESULTS: We include 14 patients diagnosed to have post COVID LTS, one female and 13 males. This group was compared with a control group, diagnosed with LTS following prolonged intubation. In the COVID group, mean age of patients at the time of the airway surgery was 52.1 ± 16.8 years (range: 13.7-76.3). More than half the patients were multi-morbid with hypertension and obesity being the most common conditions. Eleven patients had multi-site stenoses. Open surgical interventions performed were tracheal resection and anastomosis, laryngotracheal reconstruction and extended cricotracheal resection, and postoperative complications were seen in 12 (85.6%) patients. 70% patients with pre-existing tracheostomy were decannulated. Oral swallowing was not tolerated in one-fifth of the patients and a significant number of them have poor voice quality. CONCLUSION: Post-COVID pandemic, airway surgeons are seeing an increased number of patients with complex LTS, and we report significant postoperative complications in this patient subset. Decannulation rates, voice and swallowing results are poor in patients with glottic involvement as compared to isolated tracheal stenosis.

PURPOSE: To examine the factors that affect graft healing after laryngotracheal reconstruction (LTR). METHODS: We conducted a retrospective chart review at King Abdulaziz University Hospital, Riyadh, Saudi Arabia, between January-2008 and October-2023. We included all patients who underwent LTR and required anterior and/or posterior graft placement, while those who underwent procedures without graft placement and those with incomplete information were excluded. RESULTS: Forty-nine patients were analyzed. Most patients were pediatric (65.3%), male (65.3%), had no coexisting comorbidities (55.1%), and harbored grade 3-4 stenosis (59.2%). Thirty patients (61.2%) underwent open surgery. Various graft complications occurred including infection (n = 1, 2%), dehiscence (n = 3, 6.1%), scar (n = 6, 12.2%), and granulation (n = 29, 59.2%). Only 15 patients (30.65%) achieved the composite status of "healthy" graft. Among 43 patients who had postoperative cultures, positive results for Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus were observed in 10 and four patients, respectively. Open surgery and double-stage procedure were significantly associated with higher rates of granulation tissue formation. Pediatric-age group had significantly higher rate of complete epithelization compared to adult-age group. A significantly greater proportion of patients who had unhealthy grafts had open surgery. The rate of double-stage LTR was significantly higher in unhealthy grafts compared to healthy grafts. Prolonged stent duration was linked to various graft-related complications. Multivariate logistic regression analyses showed no statistically significant correlations between various factors and postoperative graft-related complications. CONCLUSION: Open surgery, double-stage procedure, pediatric age group, and stent duration were not significant risk factors associated with postoperative graft-related complications during LTR in multivariate analysis.

Tracheobronchial tuberculosis is one of the conditions causing long segment tracheal stenosis and is a clinically challenging scenario. This report describes a successful tracheal reconstruction in a 44-year-old man with long-segment post-tuberculosis tracheobronchial stenosis, utilizing a stented cryopreserved aortic allograft. The procedure was necessitated by the failure of conventional treatments. The stenotic segment was resected and replaced with a cryopreserved aortic allograft, supported by a metallic stent to maintain airway patency. Post-surgery, the patient experienced resolution of dyspnea without major complications. Currently, at 33 months post-operation, the patient enjoys an enhanced quality of life with effective breathing, speaking, swallowing abilities, and has resumed normal daily activities, with regular bronchoscopic follow-ups. This report demonstrates a novel approach for managing challenging tuberculosis-induced long segment airway stenosis.

PURPOSE: Long-term outcomes of slide tracheoplasty in patients with congenital tracheal stenosis (CTS) have rarely been reported. This study aimed to clarify the long-term outcomes of CTS after slide tracheoplasty. METHODS: The medical records of 33 patients who underwent slide tracheoplasty for CTS at our institution between January 2005 and July 2018, with a follow-up duration > 5 years, were retrospectively reviewed. Patients' characteristics, perioperative condition, operative management, postoperative course, tracheal stenosis rates and growth data, were collected from medical records. RESULTS: The median operative age, minimum tracheal diameter, length of stenosis, duration of hospital stays, and follow-up duration were 8 months, 2.4 mm, 35 mm, 39 days, and 90 months, respectively. One patient died of bleeding in the right lung at 126 months postoperatively. Among the 10 patients requiring postoperative tracheostomy, seven were successfully decannulated at a median of 65 months postoperatively. Tracheal stenosis rates improved postoperatively and were subsequently maintained. Growth impairment and psychomotor delay were observed in 9 and 16 patients, respectively with significant differences found only in cases with genetic abnormalities and not in tracheal stenosis severity. CONCLUSION: Slide tracheoplasty for CTS leads to favorable long-term outcomes. However, various associated anomalies may influence growth and psychomotor development, emphasizing the importance of adequate support.

OBJECTIVES: Airway reconstruction for laryngo tracheal stenosis (LTS) improves dyspnoea. There is little evidence relating to impact upon voice and swallowing. We explored voice and swallowing outcomes in adults with LTS before and after reconstructive surgery. DESIGN: Outcome measures were collected pre-reconstructive surgery, two-weeks post-surgery and up to 4-6 months post-surgery. SETTING: Tertiary referral centre. PARTICIPANTS: With ethical approval, twenty consecutive adult (≥18 years) LTS patients undergoing airway reconstruction were prospectively recruited. MAIN OUTCOME MEASURES: These included physiological values (maximum phonation time (MPT) and fundamental frequency; penetration aspiration score, residue score), clinician-reported (GRBAS, functional oral intake score, 100ml Water Swallow Test) and patient-reported outcomes (Voice Handicap Index-10, Reflux Symptoms Index, Eating Assessment Tool, Dysphagia Handicap Index). RESULTS: The observational study identified patient-reported and clinician-reported voice and swallow difficulties pre- and post-surgery; median and interquartile range are reported at each time point: Voice Handicap Index-10 23 (8-31); 20.5 (9-33.5), 24.5 (12.5-29); Dysphagia Handicap Index 9 (0-37); 13 (7-44); 15 (4-34); GRBAS grade 1(1-2); 2 (1-2.5); 2(1-2); 100ml Water Swallow Test volume score 16.7 (11.1-20); 14.3 (12.5-16.7); 16.7 (14.3-20.0); 100ml Water Swallow Test capacity score 16.3 ± 9.0; 11.0 ± 4.1; 12.5 ± 2.6. CONCLUSIONS: We present the first prospective data on voice and swallowing outcomes in adults with LTS before and after reconstructive surgery. The variability of the outcomes was higher than expected but importantly, for many the voice and swallow outcomes were not within normal limits before surgery. The clinical value of the study demonstrates the need for individual assessment and management of LTS patients' voice and swallowing.

Idiopathic subglottic stenosis is a circular scarred narrowing of the airway at the transition from the cricoid cartilage to the trachea. The stenosis is found radiologically and endoscopically at the level of the cricoid cartilage without involvement of the cricoid or tracheal cartilage itself. The disease practically only affects women between the ages of 20 and 60. The same clinical picture occurs in granulomatosis with polyangiitis and less frequently in other autoimmune diseases, where it requires systemic treatment. The clinical picture usually begins insidiously with coughing and sputum production and leads to dyspnoea and a restricted cough. As the course is insidious and the patients are otherwise healthy, the symptoms are often misinterpreted and the diagnosis is delayed. Treatment consists of local measures, ranging from dilatation and laser surgical resection, sometimes with local application of medication to inhibit the proliferation of new scar tissue, to laryngotracheal resection of varying degrees. The disease is located in the border area between the trachea and larynx and the patients are therefore treated by ENT medicine, pneumology and thoracic surgery.

A tracheostomy is usually necessary for long-term mechanical ventilation or complicated weaning. Other indications include swallowing disorders with recurrent aspiration in neuromuscular disease and high-grade subglottic stenosis. The tracheostomy can be performed as a percutaneous dilatational tracheostomy or as a surgical tracheostomy. The complication rate is low, and intraoperative complications are differentiated from early and late postoperative complications. This article aims to present the indications, the techniques and complications of percutaneous dilatational and surgical tracheostomy, and highlights the long-term complications of tracheal stenosis and tracheomalacia.

Benign tracheal stenosis (BTS) is a refractory disease with a complex pathogenesis and limited therapeutic drug effects. The management of benign tracheal stenosis remains a major challenge for the interventional physiologist. In recent years, the role of infection in the occurrence and development of tracheal stenosis has attracted some attention, but there is still some controversy. A clear understanding of the relationship between infection and tracheal stenosis is essential to elucidate the pathogenic mechanism of BTS, and then to improve early prevention and management of BTS. This article reviewed the research progress on BTS associated with infection to explore new effective interventions that can reduce the BTS.

OBJECTIVE: To present modern aspects of improving surgical techniques in tracheal resection developed in recent years. MATERIAL AND METHODS: The authors have the most extensive experience in tracheal surgery (>2.000 patients over the past 50 years). Diagnostic capabilities, perioperative management and surgical techniques have changed over such a long period. This concerns the proposed classification of cicatricial tracheal stenosis, features of endoscopic and X-ray diagnostics, indications for various surgeries, choice of surgical approach, technique of tracheal tube mobilization and anastomosis after tracheal excision. Preventive measures for severe postoperative complications are described. CONCLUSION: Such an extensive experience allowed the authors to develop an algorithm for the treatment of patients with tracheal stenosis. This significantly reduced the incidence of postoperative complications and mortality.

Endoscopic approach with recanalization and stenting is one of the methods for cicatricial tracheal stenosis. Major complications may occur if service life of stents is not observed. However, there are currently no clear timing for stenting. In world practice, there are no indications on lifelong stenting for cicatricial tracheal stenosis. Restenosis is more common after stent removal and requires repeated stenting or another treatment. In case of prolonged stenting, silicone stent should be periodically replaced with a similar one due to destruction of silicone rubber. As a rule, this maneuver is necessary after 1-3 years. Currently, there is no information about maximum allowable duration of stent without replacement and possible complications. Condition of trachea after prolonged stenting is also unknown. We present long-term (27 years) tracheal stenting with a silicone stent. Stent fragmentation and dislocation throughout this period led to respiratory failure and emergency removal. Tracheal lumen was satisfactory immediately after procedure. However, restenosis appeared after 1.5 months and required endoscopic dilation with discussion of appropriate treatment option. However, the patient refused tracheal resection with anastomosis and underwent repeated stenting with similar stent and favorable immediate result.
