“…And the complications are similar among two types of the stents in most conditions which included migration, granulation, diminished mucociliary clearance and patient intolerance. Previous studies have reported the complication rate of 16.1-40.9% in re-establishment of airway with Y stents and 31.3-44.4% with SEMS (15)(16)(17).…”

Background: Airway stenting is frequently used in the palliative treatment of patients with advanced tumor-induced airway stenosis and fistulas. However, there is paucity of studies regarding the use of airway stents in restoring patency. The aim of the study was to assess the efficacy and safety of hybrid silicon Y stents and covered self-expanding metal stents (SEMS) and in reestablishing patency in airway stenoses and fistulas. Methods: This retrospective study included 31 patients between January 2016 to December 2019 with inoperable complex malignant airway stenoses and fistulas, managed with Silicone Y stents, and covered SEMS. The clinical details, clinical outcomes and complications up to 6 months were extracted from medical records. The improvement of performance was assessed based on modified British Medical Research Council (mMRC) dyspnea scores (t=6.892, P<0.001), Karnofsky Performance Scores (KPS) (t=−11.653, P<0.001), and performance status (PS) (t=3.503, P<0.001). Result: A total of 31 silicon Y stents and 35 covered SEMSs were inserted. Of the 31 patients (M:F 20:11; age: 54.64±9.57), 25/31 (80.6%) experienced immediate relief of symptoms following stent placement.Patients' mMRC dyspnea scores, KPS, and PS showed significant improvement following stenting. The mean duration of stent placement was 146.3±47.7 days, and 17/31 (55%) patients were alive at 6 months. No major complications related to hybrid stenting were observed during the follow-up period.Conclusions: Hybrid stenting is a feasible and safe palliative treatment for malignant airway stenosis and fistulas to improve quality of life and can be performed without major complications.

“…Different types of airway stents have been studied, including Y silicone airway stents [9–11] and self-expanding metallic airway stents [12–17]. The silicone airway stent is one of the most common types of stent, and often shows advantages of easy removal, durability and low cost when compared with metallic stents [7, 9, 18–20]. Silicone Y-stents have been inserted in the main carina and the right upper carina [7, 11, 21–23], and the secondary left carina [8, 10].…”

“…Currently, metallic Y stents are available and used clinically. Individualized metallic Y stents can be produced upon request and are designed to fit on the main carina [9]. Besides, silicone stent can be placed under a rigid bronchoscope by a respiratory physician.…”

BackgroundFew studies have reported the placement of metallic Y-shaped covered stents (Y stents) for bronchopleural fistula around the upper carina.MethodsEighteen patients were treated with Y stents insertion under the guidance of fluoroscopy. All covered stents were custom-designed and inserted to fit the upper carina anatomy. Clinical data and medical imaging data were analyzed retrospectively.ResultsThe stents were implanted successfully for the first time in 17 patients, and one patient needed a second attempt due to stent migration during withdrawal of the guide wires. In total, 19 small Y single-plugged stents were inserted in the upper carina and 5 large Y stents additionally in the main carina. Nineteen complications were observed in 14 patients, including 4 major complications. Stents were successfully removed in 12 patients due to complications or cure efficacy, for a median duration in place of 89.5 days. One patient lost follow-up. Nine patients were cured, and three had clinical improvement. One patient died of ventricular fibrillation the second day after the procedure and 4 patients died of tumors 7.8 to 91.7 months after stent placement. The 1-, 3-, and 5-year survival rates were 87.5, 80.8 and 80.8%, respectively.ConclusionsMetallic Y stent placement is technically feasible, effective and safe for bronchopleural fistula disease around the upper carina.

“…It has been shown that a larger radial/bending strength, correlated with higher contact force between stent and the lesion, could mitigate the migration of a straight stent [24]. The concern of migration was much relieved for both the J-and Y-shaped stents, because each junction configuration, itself, constrained the migration of the stent in a bifurcated lesion [25]. The fatigue behavior of the J-shaped and Yshaped stents might be essential due to inspiration and expiration following stenting [26].…”

The self-expandable metallic stents have been widely used in tracheobronchial obstruction or fistulation, including the J-shaped and Y-shaped stents, named after the shape of the branch-stem junction of the stent. However, there is scarce data on the mechanical performance of these tracheobronchial stents, which is essential for optimal stent implantation. In this work, eight self-expandable metallic tracheobronchial stents in three types (i.e., straight, J-shaped, and Y-shaped), with or without cover, were characterized. The compression resistance of the stems was investigated through both compression and indentation tests. The bending resistance of the branches in the J-shaped and Y-shaped stents was assessed through the bending test. Our results demonstrated that the covered stents exhibited a significantly higher compression resistance and bending resistance than the uncovered ones. The branches had a minimal impact on the compression resistance of the stem. The branch of the J-shaped stent showed a significantly lower bending resistance than the Y shaped one. This work provides a testing framework for the J-shaped and Y-shaped stents,which could shed some light on the optimal design of stent with branches.
