Abstract
INTRODUCTION Benign tracheobronchial stenosis is a abnormal tracheal lumen narrowing that may incur progressive dyspnea and life-threatening hypoxemia. There is no consensus on which patients should be treated with endoscopic or surgical method. This study investigates the outcomes of bronchoscopic dilatation in the treatment of benign tracheal stenosis using a device equipped with a blade to cut the stenotic lesions with dense fibrosis. MATERIALS AND METHODS The procedure was carried out in an operating room under general anesthesia. All patients were intubated with a Rigid Bronchoscope (RB) placed just above the stenosis. Through Rigid Bronchoscopy combined modalities were used as needed: radial incisions of the mucosal stenosis with blade at the levels of 4, 8 and 12 o'clock, with back and forth movements, then the stenotic area was dilated more easily with a rigid bronchoscope. Dilatation was performed by passing the RB of increasing diameter through stenotic areas and then Balloon dilatation of increasing diameter. There were no complications during the procedure. RESULT We conducted an observational, retrospective, single-centre study in the Thoracic Surgery Unit of the University of 'Luigi Vanvitelli' of Naples from November 2011 to September 2021. We included all consecutive patients with benign tracheal stenosis inoperable. During the study period, 113 patients were referred to our department with benign tracheal stenosis inoperable. 61 patients were treated with the blade. During the follow-up, a recurrence of the stenosis was observed in 8 patients in the first month and in 4 patients in the third month. Instead in the patients treated with the use of laser (52 patients), during the follow-up a recurrence was observed in 16 patients in the first month and in 6 patients in the third month; no patient relapsed after 6 months and after 1 year. Long term successful bronchoscopic management with blade was attained by 99% in simple and 93% in mixed stenosis and in complex type stenosis. CONCLUSION Our study underlines the importance of the use of the blade in bronchoscopic treatment as a valid conservative approach in the management of patients with inoperable benign tracheal stenosis as an alternative to the use of the laser, reducing the abnormal inflammatory reaction in order to limit recurrences.

Abstract
The systematic review aims to evaluate the efficacy and safety of endobronchial stent placement for malignant airway obstruction. A comprehensive search was conducted across multiple databases to identify relevant studies. Cohort studies, randomized controlled trials, and case-control studies examining the outcomes of endobronchial stent placement in patients with malignant airway obstruction were included. Data on pre-treatment evaluation, such as pulmonary function testing, dyspnea severity scoring systems, arterial blood gas parameters, imaging, and degree of obstruction, were also collected. Primary outcomes of interest included post-procedure stenosis, pulmonary function testing evaluation, blood gas parameters, and survival outcomes. Secondary outcomes encompassed improvements in clinical status, dyspnea grade, and procedure-related complications. A total of 27 studies met the inclusion criteria and were included in the systematic review. The included studies demonstrated promising outcomes of endobronchial stent placement in managing malignant airway obstruction. Post-procedure airway diameters, pulmonary function testing, and blood gas parameters improved significantly. Survival outcomes varied among studies. Furthermore, endobronchial stent placement was associated with improvements in clinical status and dyspnea grade. Procedure-related complications ranged from pain, hemoptysis and mucus plugging to stent obstruction, migration and pneumothorax. This systematic review suggests that endobronchial stent placement is an effective and safe intervention for managing malignant airway obstruction. It offers significant improvements in post-procedure stenosis, pulmonary function testing, blood gas parameters, and clinical outcomes. However, further studies with larger sample sizes and standardized reporting are warranted to better evaluate the long-term efficacy and safety of endobronchial stent placement for malignant airway obstruction.

Abstract
Background Central airway obstruction and fistula are treated with a tracheobronchial Y stent. In the currently used self‐expandable metal Y stents, the delivery system is 8 mm in diameter and requires either a 9 mm tracheal tube or rigid bronchoscope to enable airway control during insertion. In this study we present a novel technique of laryngeal mask airway (LMA) assisted Y stent insertion, enabling airway control during deployment of the Y stent. Methods All procedures using LMA in assisting Y stent insertions between 2014–2020 were reviewed. Data collected included demographics, clinical diagnosis and disease characteristics, indication, procedural success rates, clinical outcome and survival. Results A total of 10 patients with a median age of 61.5 years (range 37–73) underwent LMA assisted Y stent insertion. Indications for stent insertion were malignant disease with central airway obstruction or fistula. In all cases airway patency was achieved leading to improvement of symptoms and performance status. No procedural complications were reported. The median survival was 4.5 weeks (range: 2–26). Conclusions LMA assisted Y stent insertion enables airway control during the procedure. In comparison to silicone Y stent insertion, the procedure is less cumbersome, shorter in duration and does not require the use of general anesthesia or rigid bronchoscopy. Key points Significant findings of the study LMA assisted Y stent insertion enables airway control during the implantation of metallic self‐expanding Y stent. The procedure does not require the use of general anesthesia or rigid bronchoscopy. What this study adds In this study we present the technique and outcomes of LMA assisted Y stent insertion. This method of Y stent insertion provides an additional treatment option for patients with central airway obstruction and fistula.

Abstract
Background Self‐expandable metallic stent (SEMS) placement is an urgent procedure for patients with malignant central airway stenoses (CASs) and central airway fistulas (CAFs). The aim of this study was to determine the outcome and survival after SEMS placement in patients with malignant CASs and CAFs. Methods SEMSs were inserted into 20 patients with malignant CASs and four with malignant CAFs. Hospital records, the modified Medical Research Council dyspnea scale (mMRC) grade, performance status (PS), symptoms, procedure‐related complications and survival after placement were retrospectively reviewed. Results Spiral Z stents were inserted in nine patients, covered Ultraflex stents in 14, and a bare Ultraflex in one patient. After SEMS placement, 20 patients (83.3%) showed improvement in mMRC grade, 19 (79.2%) showed improvement in PS, and 21 (87.5%) showed improvement in symptoms. There were three patients whose stents migrated out of place, but there were no patients with obstructive granulation, infection, or mucous plugs. Median survival days after stent insertion was 98 days for CAS and 103 days for CAF, and mean survival days was 383 ± 707 days for CAS and 93 ± 33 days for CAF. Two patients with CAS by malignant lymphoma and thymic cancer survived more than six years because they were also treated with efficient therapies. The five‐year survival rate after stent insertion was 7.7%. Conclusions SEMS placement for CAS and CAF is associated with improvement in mMRC grade, PS and symptoms in 87.5% of patients. Patients with a malignant CAS are usually terminal, but the possibility of increasing survival rate will become a reality with new efficient therapies. Key points Significant findings of the study Reasonable clinical outcomes and improved survival of patients following SEMS placement for thoracic malignancy with central airway stenosis and fistula.
What this study adds The possibility of increasing survival rate will become a reality with new efficient therapies.

Self-expanding metallic Y-stent compared to silicone Y-stent for malignant lesions of the main carina: A single center retrospective study. Respir Med Res 2020; 78:100767. [PMID: 32498021 DOI: 10.1016/j.resmer.2020.100767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2020] [Revised: 05/04/2020] [Accepted: 05/08/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND Bifurcation stents are often required in patients with malignant airway obstruction or fistulization involving the main carina. The silicone Y stent is the most used but remains challenging to place. The self-expanding metallic Y (SEM) stent appears easy to use. The objective is to report the feasibility, efficacy, and tolerance of SEM Y stent compared to silicone Y stent in patients with malignant tumors involving the main carina. PATIENTS AND METHODS This retrospective single center study was performed between May 2004 and May 2017. All patients with malignant carina involvement treated with a bronchial Y stent were included. RESULTS Forty silicone Y stents and 38 SEM Y stents were placed. Seven stenting placements failed in the silicone Y group but none in the SEM Y stent group (P=0.008). The median duration of the procedure was 80min (25-210) in the silicone Y group and.50min (25-110min) in the SEM Y group (P=0.001). There was no significant difference in terms of early or late complications between the 2 groups. Nine silicone Y stents (26.5%) and 7 SEM Y stents (18.4%) were removed (P=0.4). The median survival time following stent insertion was 171 days (Interquartile range (IQR): 53-379) in the silicone Y group and 104 days (IQR: 53-230) in the SEM Y group. CONCLUSION If silicone Y stent remains the best solution for benign obstruction, SEM Y stent seems to be an easy alternative with no difference in terms of complication or ablation for malignant lesions involving the main carina.

Abstract
Background Self-expandable metallic Y-shaped airway stents (SEMYS) are commonly used in the management of airway stenosis and fistulae caused by thoracic neoplasms. Methods A new technique using a slightly modified regular endotracheal tube has been developed for the deployment of SEMYS with flexible bronchoscopy alone. The technique and devices are described. Results To date, successful deployment of SEMYS with this method has been carried out successfully in 17 out of 20 patients without major complications while the other 3 required conversion to rigid bronchoscopy because of limited pharyngeal cavity space, massive hemorrhage and severe cicatrization of the airway, respectively. Conclusions This simplified deployment technique with the modified endotracheal tube enables safe, simple and fast insertion of SEMYS in a regular bronchoscopy suite, which may benefit the vast less privileged institutions where SEMYS are necessary but rigid bronchoscopy and fluoroscopy are not available. The skill of the bronchoscopist, cautious selection of patients and effective coordination of the operating team are crucial for the procedure.

Abstract
Malignant carinal stenosis is a disease process that is not always suitable for treatment with a Y-shaped stent. When one of the main bronchi is completely obstructed and cannot be recanalized, or its distal lung tissue has lost function, inserting a Y-shaped stent is infeasible. In this complex condition, a cone-shaped stent is selected to maintain the patency of the trachea and the other main bronchus. The efficacy of the bare cone-shaped Micro-Tech stent to treat malignant carinal stenosis was evaluated in the current study. The medical records of 47 patients with malignant carinal stenosis who underwent Micro-Tech stent placement between January 2004 and October 2017 in Beijing Tian Tan Hospital (Beijing, China) were analyzed retrospectively. A total of 47 bare Micro-Tech stents (28 Y-shaped and 19 cone-shaped) were successfully inserted in the patients. Following stent placement, immediate satisfactory results were achieved in all patients, especially an improvement of dyspnea (100%), cough (81.1%) and stridor (100%). The Karnofsky scores were significantly increased (P<0.001), and the American Thoracic Society Dyspnea Index values were significantly decreased (P<0.001). Following a median of 88 days, initial bronchoscopic interventions were performed for tumor overgrowth (84.6%), stent fracture (7.7%) and granulation tissue (7.7%). Restenting was performed in two patients due to tumor progression (n=1) and stent fracture (n=1). Removal of a Y-shaped stent was attempted in one patient, but failed, as the stent had become partly embedded in the airway mucosa. In conclusion, cone-shaped Micro-Tech stent placement maintained tracheal-unilateral main bronchus patency and benefitted patients with malignant carinal stenosis in whom Y-shaped stents were not suitable for insertion.

Abstract
Purpose: Surgical resection and reconstruction are considered the most appropriate approaches to treat post-intubation tracheal stenosis (PITS). Bronchoscopic methods can be utilized as palliative therapy in patients who are ineligible for surgical treatment or who develop post-surgical re-stenosis. We investigated treatment outcomes in patients with benign tracheal stenosis. Methods: A retrospective review was performed in patients who were diagnosed with PITS. Tracheal resection was performed for operable cases, whereas endoscopic interventions were preferred for inoperable cases with a complex or simple stenosis. Results: In total, 42 patients (23 treated by bronchoscopic methods, 19 treated by surgery) took part in this study. No significant differences were observed in segment length, the proportion of obstructed airways, or vocal cord distance between the two groups. In all, 15 patients in the bronchoscopic treatment group received a stent. Following the intervention, the cure rates in the bronchoscopic and surgical treatment groups were 43.47% and 94.7%, respectively. A multidisciplinary approach resulted in a cure or satisfactory outcome in 90.5% of the patients while failure was noted in 9.5% of the patients. Conclusion: Bronchoscopic methods are associated with a lower cure rate compared to surgery. A multidisciplinary approach was helpful for treatment planning in patients with PITS.
