Abstract Background Long-term placement of airway stents has a high probability of restenosis of the airway due to granulation tissue hyperplasia, and it is difficult to remove the stent. Our aim is to evaluate the success rate and complications of removal of tracheal tube metallic stents under fluoroscopic guidance, and to compare the difference between uncovered stent and covered stent. Methods We retrospectively reviewed 45 cases (31 males and 14 females; age, 12–71 years) of tracheal metallic stent removal performed at our center between January 2014 and December 2019. Covered stents were applied in 36 cases, and uncovered stents were applied in 9 cases. In the covered stent group, 15 patients presented with granulation tissue at both ends; 3 cases, with stent fracture; and 2, with stent intolerance due to severe airway foreign body sensation. In the uncovered stents group, all patients presented with granulation tissue formation; 2 patients, with stent fracture; and 1 patient, with stent intolerance. Results A total of 41 (91.1%) stents were successfully removed (34 [94.4%] in the covered stent group and 7 [77.8%] in the uncovered stent group). The average duration of stent placement was 3.2 ± 0.7 and 2.5 ± 1.2 months in the covered stent group and uncovered stent group, respectively. With regard to the complications, hemoptysis occurred in 4 cases (average blood volume lost, 100 ml), tracheal mucosa tear occurred in 5 cases, tracheal collapse requiring emergency airway stent placement occurred in 1 case, and tracheal rupture requiring emergency surgical suture occurred in 1 case. No procedure-related deaths occurred in either group. Conclusions It is safe to remove the metal stent of the tracheal tube under the guidance of fluoroscopy, with low complications, and can avoid the long-term placement of the airway stent.

Recently, more and more researchers have focused on airway stent applied in tracheomalacia. The airway stents for clinical application were usually manufactured in accordance with a fixed pattern, which were difficult to perfect match with children, especially infants. Digital light procession of light curing acrylate resin implantation showed higher accuracy and printing speed over traditional three-dimensional printing techniques. In this article, a novel personalized airway stent was developed by digital light procession three-dimensional printing and was modified by collagen I extracted from the fish scales. The morphology of the collagen-modified airway stent was examined by scanning electron microscopy, and the chemical structures were examined by attenuated total internal reflectance Fourier transform infrared spectroscopy. The biocompatibility of this synthetic acrylate/collagen composite airway stent was characterized by water contact angle test and cell culture. The results confirmed that the composite airway stent was hydrophilic and non-cytotoxic toward a cultured human bronchial epithelial cell line with good cell viability and show excellent physicochemical and biological properties. In conclusion, this study presented the three-dimensional printing composite acrylate and collagen airway stent may have potential in customized treatment for tracheomalacia.

Abstract Introduction This cross-sectional study evaluated a novel nasal airway stent (NAS) in the form of a single-use, disposable device (naśtent® classic, Seven Dreamers Laboratories, Inc., Tokyo, Japan), which represents a significant advancement in NAS technology for the treatment of OSA. Methods 1353 individuals whom were interested in NAS treatment for their snoring and/or OSA were enrolled in this study conducted in different districts in Tokyo, Japan from 8/21/2015 to 3/7/2016. A total of 1335 participants with complete data were included in the final dataset. Collected data included demographic features, self-reported sleep and OSA characteristics, anatomic traits, Epworth Sleepiness Scale (ESS) scores, and NAS tolerance. Results The majority of the participants were middle-aged men (91.5% male, 45±10.8 years) with normal BMI (24.5±5.7). Self-reported sleep was 9-11 hours (0.1%), 7-9 hours (8.2%), 5-7 hours (66.7%), 3-5 hours (22%), 1-3 hours (1.2%), and unreported (1.9%). Their mean Epworth Sleepiness Scale score was 9±5.56, and their peak Mallampati and tonsillar grading scores were 2/4 and 3/5, respectively. Of the participants, 87.4% were aware of possible OSA either by snoring or by prior diagnosis of OSA, and their reasons for desiring use of NAS therapy presented in a similar ratio. Over 80% of the participants had never been treated for their diagnosis of OSA; for those with current or prior treatment for their OSA, 62.9% reported PAP as their primary therapy, followed by oral appliances (25.7%), surgery (0.5%), and other therapies (10.8%). On a scale of 1 to 5 where 5 indicated good tolerance to the NAS, the mean scores were 4±1.3 for easy of insertion and 4±1.2 for convenience of use. Conclusion This large, cross-sectional study indicated that the majority of individuals seeking a novel NAS treatment for their snoring and/or OSA in Tokyo, Japan were middle-aged men with 5-7 hours of self-reported sleep whom had some daytime sleepiness, displayed signs of mild anatomic upper airway narrowing, had not been treated for their OSA, and whom felt that the NAS was easy and convenient to use.
