  • [Title] Removal of self expandable metallic airway stent: A rare case report.
  • Covered self expandable metallic airway stents (SEMS) have been used for benign tracheal stenosis, post intubation tracheal stenosis, tracheal burn or trauma, tracheo-broncho-malacia, and extrinsic compression of trachea.
  • Their placement is considered to be permanent, with open surgery the only way to remove the stent, though there are few cases reports of their removal with the bronchoscope, but the complications after their removal are very high.
  • In our patient, one and a half years after placement of SEMS, she developed cough with dyspnoea, video bronchoscopy showed stenosis above the level of stent with granulation tissue inside the stent, stent fracture in lower part and stent migration to right main bronchus, thus she had all conceivable complications of stent placement.
  • The stent was removed with the help of rigid bronchoscope under general anaesthesia.
  • The case is being reported because it was unique in having all the possible complications of stent placement, and rare as we could take out the stent in Toto.
  • Thirdly, the stent could be removed without any complication.

  • [Title] Preliminary study for a newly designed silicone stent and delivery system for canine obstructive tracheal disease.
  • The goal of this study was to prove the possibility of using silicone stents broadly used for human medicine in canine obstructive tracheal disease.
  • A silicone stent anatomically designed for canine trachea was tested on 5 beagle dogs for 8 weeks.
  • The stent was carefully inserted using a newly developed delivery device under fluoroscopic guidance.
  • There were no technical difficulties in placing the stent during the procedure.
  • Previously reported complications of airway stenting such as stent migration or granulation tissue formation did not occur in any of the cases.
  • In addition, removal of the stent was as simple as inserting it, and complications were absent.
  • The stent introduced in this study could possibly be applied to various canine obstructive tracheal diseases.

  • [Title] Management of complex benign post-tracheostomy tracheal stenosis with bronchoscopic insertion of silicon tracheal stents, in patients with failed or contraindicated surgical reconstruction of trachea.
  • Tracheal stenosis is a potentially life-threatening condition.
  • In symptomatic benign tracheal stenosis the gold standard is surgical reconstruction (often after interventional bronchoscopy).
  • Stenting is reserved for symptomatic tracheal narrowing deemed inoperable, due to local or general reasons: long strictures, inflammation, poor respiratory, cardiac or neurological status.
  • When stenting is decided, silicone stent insertion is considered the treatment of choice in the presence of inflammation and/or when removal is desirable.
  • We inserted tracheal silicone stents (Dumon) under general anaesthesia through rigid bronchoscopy in two patients with benign post-tracheostomy stenosis: a 39-year old woman with failed initial operation, and continuous relapses with proliferation after multiple bronchscopic interventions, and a 20-year old man in a poor neurological status, with a long tracheal stricture involving the subglottic larynx (lower posterior part), and inflamed tracheostomy site tissues (positive for methicillin resistant staphylococcus aureus).
  • At 15- and 10-month follow-up (respectively) there was no stent migration, luminal patency was maintained without: adjacent structure erosion, secretion adherence inside the stents, granulation at the ends.
  • The patients maintain good respiratory function and will be evaluated for scheduled stent removal.

  • The aim of the study was to assess the feasibility, efficacy and safety of the use of a conical self-expandable stent for the treatment of post-pneumonectomy bronchopleural fistula (PPBPF).
  • Between April 2008 and November 2010, six patients underwent treatment for the PPBPF by the introduction of a tracheobronchial conical fully covered self-expandable nitinol stent with the aim of excluding the bronchial dehiscence from the airflow.
  • We secured the prosthesis to the tracheal mucosa with titanium helical fasteners tacks.
  • One patient had an anastomotic dehiscence after right tracheal sleeve pneumonectomy.
  • The bronchial stent was successfully removed in all patients without sequelae 71-123 days after its implantation.
  • The use of the conical self-expandable Silmet(®) stent has proved to be an effective, safe and fast method to treat even large PPBPFs.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Of those 20 patients, 16 had post-intubation tracheal stenosis (PITS), 2 had tracheal stenosis due to inhalation burn (IBTS) and other 2 had obstructive fibrinous tracheal pseudomembrane (OFTP).
  • For treatment, silicone stent insertion was done in 16 cases of PITS and IBTS and mechanical removal was performed in 2 cases of OFTP.
  • In all cases of stent, airway obstructive symptom improved immediately.
  • CONCLUSION: Tracheal stenosis was most common indication and silicone stenting was most common procedure of rigid bronchoscopy in our center.
  • Rigid bronchoscopic procedures, at least tracheal silicone stenting, should be included in pulmonary medicine fellowship programs because it is a very effective and indispensable method to relieve critical airway obstruction which needs training to learn.

  • [Title] Decannulation in tracheal stenosis deemed inoperable is possible after long-term airway stenting.
  • BACKGROUND: Decannulation is the ultimate therapeutic goal for patients who undergo stenting because of inoperable benign tracheal stenosis.
  • In this study, our objectives were to evaluate whether long-term airway stenting allows decannulation in patients with benign tracheal stenosis who were deemed inoperable and to identify possible predictive factors for successful decannulation (SD).
  • METHODS: Retrospective cohort study including all patients with inoperable benign tracheal stenosis who underwent tracheal stenting in our tertiary-care university-based institution from 1998 to 2008.
  • The main outcome was SD, which was defined as removal of the tracheal stent followed by absence of respiratory symptoms and no requirement for new dilation procedures for at least 6 months.
  • Cox regression showed only 1 significant factor: tracheostomy before stent insertion caused a threefold increase in the likelihood of the patient remaining with a tracheal stent (p = 0.048).
  • CONCLUSIONS: Tracheal stenting may be considered a curative therapeutic approach in as many as 27.5% of patients with inoperable benign tracheal stenosis.

  • [Title] Natural stent in the management of post-intubation tracheal stenosis.
  • BACKGROUND AND OBJECTIVE: The treatment choice for post-intubation tracheal stenosis (PITS) in patients for whom surgery is not initially feasible is bronchoscopic silicone stenting.
  • A new silicone stent, called the Natural stent (N stent), was investigated for its clinical efficacy and safety in patients with PITS.
  • RESULTS: Airway dilatation with combined modalities such as Nd:YAG laser, ballooning or bougienage was followed by N stent insertion.
  • Removal of the stent without re-stenosis was successful in 38% of the patients at a median time of 7 months after insertion.
  • The stent could not be removed or needed reinsertion in 31% of patients, and 16% of patients underwent surgery after initial stabilization by stenting.
  • Late complications were stent migration (34%), mucostasis (31%), granulation tissue formation (38%) and re-stenosis (40%).
  • Further stent development is necessary to reduce the late complication rate.

  • [Title] Tracheal stricture and fistula: management with a barbed silicone-covered retrievable expandable nitinol stent.
  • OBJECTIVE: The purpose of this study was to evaluate the safety and effectiveness of a barbed silicone-covered retrievable expandable nitinol stent in preventing stent migration in patients with tracheal strictures or fistulas.
  • SUBJECTS AND METHODS: Under fluoroscopic guidance, barbed silicone-covered retrievable expandable nitinol stents were placed in 15 patients with tracheal strictures, two patients with fistulas, two patients with combined strictures and fistulas, and one patient with variable extrathoracic airway obstruction.
  • The three pairs of barbs were attached to the external stent surface at the middle of the stent at equal intervals.
  • No stent migration occurred, even in the three patients without fixed strictures.
  • Four stents subsequently were removed because of complications, and one stent was removed because the patient's condition improved.
  • Stent removal was not difficult and was uneventful.
  • CONCLUSION: Use of a barbed silicone-covered retrievable expandable nitinol stent relieves dyspnea and facilitates fistula closure in patients with benign or malignant tracheal strictures or fistulas.
  • The barbed design of the stent is important in preventing migration.

  • [Title] Determination of predictive factors of tracheobronchial prosthesis removal: stent brands are crucial.
  • OBJECTIVES: We sought to describe in a retrospective study our experience in the endoscopic management of tracheobronchial stenoses over 20 years and to determine prognostic factors of stent removal.
  • The incidence of complications for the first stent was 0.08 per patient-month.
  • In univariate analysis, stent removal was significantly linked with the stent brand.
  • In multivariate analysis, taking into account the causes of stenosis, the stent brand appeared to be the only factor that significantly influenced stent removal.
  • Finally, stenosis with more than 1 stent replacement was most prone to repeat endoscopies.
  • CONCLUSIONS: Even though endoscopic stent placement is a relatively safe and effective treatment for tracheobronchial stenoses, particularly in cases with malignancy, complications led to stent removal in about one third of cases.
  • The type of stent chosen is crucial.

  • [Title] Treatment of cuff-related tracheal stenosis with a fully covered retrievable expandable metallic stent.
  • AIM: To investigate the clinical effectiveness, complications, and optimal duration of use of covered retrievable expandable metallic stents in the management of cuff-related tracheal stenosis.
  • MATERIALS AND METHODS: Twenty-one patients with cuff-related tracheal stenosis, Meyer-Cotton grade II (29%) and III (71%), who underwent fluoroscopically guided placement of covered retrievable expandable metallic stents were studied.
  • Sixty-four-section computed tomography (CT) and bronchovideoscopy were performed prior to stent insertion, 1 month after stent insertion, in the case of stent-related complications, and after stent removal.
  • Clinical manifestations, Hugh-Jones classification, and forced expiratory volume in 1 s (FEV1) were used to evaluate respiratory function before and after stent insertion and removal.
  • The diameter of the stricture and FEV1 changes before insertion and after removal were analysed using the paired samples t-test.
  • The median duration of stent placement was 5 months (range 4-12 months).
  • One stent was not removed due to mucopolysaccharidosis type II (MPS II or Hunter syndrome) with tracheomalacia.
  • After stent removal, airway dimensions increased and airway occlusion was symptomatically relieved in all patients.
  • Stent-related complications occurred in 19 (91%) patients, including granulation tissue formation (n = 18, 86%), stent migration and stent expectoration (n = 2, 10%), mucus plugging (n = 1, 5%), and halitosis (n = 6, 29%).
  • Some patients experienced multiple complications, which were all managed effectively while the stent was still in place.
  • There was a statistically significant difference in the diameter of the stricture and FEV1 between the time of stent insertion and removal.
  • An improvement in Hugh-Jones classification of greater than one grade was seen in patients after stent removal.
  • CONCLUSION: Temporary placement of a fully covered retrievable expandable metallic stent is safe and effective in cuff-related tracheal stenosis.
  • The optimal duration of stent placement may be 4-8 months.

  • [Title] Posttuberculosis tracheobronchial stenosis: use of CT to optimize the time of silicone stent removal.
  • PURPOSE: To evaluate whether air pockets (tracheobronchial air columns in the space between the outer surface of the stent and the adjacent airway wall) discernible at computed tomography (CT) can help optimize the time of stent removal in patients with posttuberculosis tracheobronchial stenosis (PTTS).
  • Data from 41 patients (five men, 36 women) with a median age of 39 years (range, 21-64 years) who underwent silicone stent placement owing to PTTS, followed by CT and stent removal 6-12 months after clinical stabilization, were investigated retrospectively.
  • Two radiologists determined whether the extent of air pockets on CT scans was associated with clinical success, which was defined as maintenance of a prosthesis-free airway for more than 2 years after stent removal.
  • Air pockets longer than 1 cm or longer than 2 cm were associated with successful stent removal (P = .04 and P = .006, respectively).
  • The sensitivity and specificity of air pocket length in the prediction of successful stent removal were 84% and 50%, respectively, for air pockets longer than 1 cm and 68% and 70% for air pockets longer than 2 cm.
  • CONCLUSION: The extent of air pockets at chest CT shows correlation with the success of stent removal, indicates regression of stenosis, and may help guide the optimal time for stent removal.

  • [Title] Tracheal replacement with cryopreserved allogenic aorta.
  • BACKGROUND: Radical resection of primary tracheal tumors may be challenging when more than one-half of the tracheal length is concerned.
  • The present study evaluated the use of cryopreserved aortic allografts (CAAs) to replace long tracheal segments.
  • METHODS: Sixteen adult minipigs underwent tracheal replacement with a CAA.
  • A silicone stent was used to splint the CAA for the first 12 months.
  • All animals studied for more than 3 months showed progressive transformation of the graft into a chimerical conduit sharing aortic and tracheal histologic patterns (eg, islands of disorganized elastic fibers/mature respiratory ciliated epithelium, respiratory glands, islets of cartilage).
  • Stent removal was attempted after 12 months in 10 animals, and critical tracheal stenosis was found in six animals and moderate asymptomatic stenosis in four.
  • CONCLUSIONS: CAA may be considered as a valuable tracheal substitute for patients with extensive tracheal tumors.

  • This case study describes typical patients with tracheal stenosis and the management of these patients.
  • In these cases, bronchoscopy revealed tracheal stenosis.
  • Dilatation and silicone stent placement were performed using rigid bronchoscopy.
  • Tracheal stenosis developing in the subglottic region after extubation, especially after exposure to cuff pressure, may lead to reintubation.
  • Early intubation-related tracheal stenosis should therefore be considered in cases of weaning or extubation failure and prompt appropriate investigation and treatment.

  • BACKGROUND: A significant native tracheal approximation phenomenon was observed in our previous study [Tsukada H, Ernst A, Gangadharan S, et al.
  • Tracheal replacement with a silicone-stented fresh aortic allograft in sheep.
  • Because an appropriate tracheal replacement graft has yet to be determined, other means to repair or replace tracheal tissue have to be evaluated.
  • The aim of this study was to test a bioabsorbable scaffold for temporary tracheal grafting.
  • METHODS: Eight male sheep underwent cervical tracheal replacement (5 cm) using a copolymer of L-lactide and ε-caprolactone sponge tube reinforced by polyglycolic acid.
  • A silicone stent (7 cm) was placed perioperatively to prevent graft collapse.
  • Computed tomographic imaging of the grafted area showed tracheal approximation up to 75% at 9 months after surgery.
  • Symptomatic airway collapse was observed at 6 hours, 1 week, and 2 weeks after stent removal.
  • CONCLUSIONS: Tracheal axial approximation occurs consistently after tracheal resection and replacement.
  • Our data suggest that bioabsorbable materials can be used as a reliable, temporary, tracheal replacement conduit.

  • [Title] Long-term outcomes of congenital tracheal stenosis treated by metallic airway stenting.
  • AIM: Congenital tracheal stenosis is an obstructive airway lesion that often presents as a life-threatening emergency.
  • We had introduced the balloon dilatation and placement of the expandable metallic airway stent as a therapeutic option, and this study aimed to clarify the long-term outcomes in pediatric patients.
  • Recently, an attempt to remove the stent was done in two patients who showed dyspnea on exertion.
  • They underwent tracheoplasty following successful complete removal of metallic stent using cardiopulmonary bypass.
  • CONCLUSION: Use of expandable metallic airway stents following balloon dilatation can be left for long periods to relieve tracheal obstruction.
  • Removal of the stent was safely completed by open surgical intervention using a cardiopulmonary bypass.
  • The airway stent may provide an important therapeutic option in selected cases with congenital tracheal stenosis.

  • [Title] Surgical technique and results of tracheal and carinal replacement with aortic allografts for salivary gland-type carcinoma.
  • OBJECTIVE: We describe the surgical technique and peroperative management of tracheal and carinal replacement with aortic allografts for large salivary gland-type carcinoma and report the results with a mean 34 months' follow-up.
  • METHODS: We performed tracheal and carinal replacements with aortic allografts in 6 patients with extensive mucoepidermoid (n = 1) or adenoid cystic (n = 5) carcinomas.
  • Tracheal tumor resection was followed by carinal restitution (n = 3) and interposition of the graft, splinted by a silicone stent.
  • Stent removal has not been attempted in any patient.
  • CONCLUSION: Tracheal replacement with aortic allografts enables resection of extensive tumors with a curative intent.

  • [Title] The management of post-intubation tracheal stenoses with self-expandable stents: early and long-term results in 11 cases.
  • OBJECTIVE: The optimal management of post-intubation tracheal stenoses is surgical reconstruction of the airway.
  • Stenting of the trachea using silastic T-tubes or one of the various types of tracheal stents are the alternative ways to surgical reconstruction for the management of post-intubation tracheal stenoses.
  • The early and long-term results of 11 patients with post-intubation tracheal stenosis, who underwent tracheal stenting with self-expandable metallic stents (SEMSs), are presented.
  • METHODS: Twelve patients (10 men, mean age: 47.8±20.4 years) with post-intubation tracheal stenosis were referred for tracheal stenting with SEMS (2000-2004).
  • In three cases, the upper tracheal stenosis extended within the subglottic larynx.
  • Stenting was successful in 11 patients, while, in one patient with involvement of the subglottic larynx, the attempt to insert the stent failed.
  • Stent dislodgement occurred shortly after the procedure in two patients, and it was treated with insertion of a new stent in the first case and a stent-on-stent insertion in the second.
  • Good patency of the stent was observed in three patients for 60-96 months.
  • Three patients with good patency of the stent died from other reasons 24-48 months after stent insertion.
  • Four patients developed obstructive granulation tissue at the ends of the stent after 12-43 months, requiring further treatment with thermal lasers and/or tracheostomy.
  • One patient underwent stent removal and successful laryngotracheal reconstruction 6 months after stent insertion.
  • CONCLUSIONS: The application of SEMS in post-intubation tracheal stenoses results in immediate improvement of obstructive symptoms without significant perioperative complications.
  • SEMSs have the potential risks of migration and of granulation tissue formation at the end of the stent.
  • SEMS should be applied only in strictly selected patients with post-intubation tracheal stenosis, who are considered unfit for surgery and/or with limited life expectancy.

  • [Title] Tracheal replacement with a silicone-stented, fresh aortic allograft in sheep.
  • BACKGROUND: Tracheal tissue regeneration after allogeneic aortic transplants in sheep has been reported.
  • METHODS: Ten male sheep underwent cervical tracheal replacement with fresh, descending thoracic aortic allografts, 8 cm long, from female sheep, without postoperative immunosuppressive therapy.
  • A 10-cm silicone stent was placed to prevent airway collapse.
  • RESULTS: There were no procedural deaths, but 6 animals died or required euthanasia between 12 days and 3 months postoperatively owing to severe tracheitis, cervical lymphadenitis, pneumonia, graft necrosis, stent migration, or airway obstruction after stent removal.
  • CONCLUSIONS: Fresh aortic allografts appear to be unsuitable for primary tracheal replacement.
  • However, the observed graft shortening may allow for two-staged, end-to-end reconstruction of large tracheal defects with temporary grafting techniques.

  • [Title] Multi-stage surgery for airway patency after metallic stent removal in benign laryngotracheal airway disease in two adolescents.
  • We present two cases of laryngeal metallic stent placement following benign airway disease.
  • Two adolescents presented with severe dyspnea and self-expandable metallic stent placement after benign laryngotracheal stenoses.
  • Granulation tissue ingrowths required additional surgical interventions every 6-8 weeks to recanalize the stent lumen.
  • We performed multi-stage surgery including removal of the embedded stent, segmental resection of the stenotic area, end-to-end-anastomosis and laryngotracheal reconstruction respectively, to achieve patent airway without tracheal cannulation.
  • In both adolescents, we achieved successful removal of the embedded stent and patent airway.
  • Stent removal, segmental resection and laryngotracheal reconstruction provide the achievement of patent airway and allow decannulation.
  • In benign laryngeal airway disease, stent placement should be avoided, especially in adolescents.
  • Transfer to a specialist center should be considered prior to metallic stent implantation.

  • [Title] Novel use of a percutaneous endoscopic gastrostomy tube fastener for securing silicone tracheal stents in patients with benign proximal airway obstruction.
  • BACKGROUND: Benign tracheal obstruction occurs for a variety of reasons.
  • Bronchoscopic intervention includes silicone stent placement, which effectively maintains airway patency.
  • Stent migration is a common complication, particularly when placed in the proximal trachea.
  • We used a novel technique of securing tracheal stents with a percutaneous endoscopic gastrostomy tube fastener (PEG-TF) to prevent stent migration.
  • METHODS: Silicone stents were placed under general anesthesia by rigid bronchoscopy in 7 consecutive patients with inoperable benign proximal tracheal obstruction.
  • A needle was inserted through the anterior neck and silicone stent wall allowing stylet introduction of a T-fastener into the interior of the stent.
  • No stent migration occurred while the fastener was in place.
  • Two stents were removed within 2 weeks due to patient's difficulty tolerating the stent.
  • CONCLUSIONS: Securing silicone stents in the proximal trachea is feasible and may prevent stent migration, but further study and possible modification of the PEG-TF device are needed.

  • Removal of a SEMS is usually performed during general anesthesia with muscle relaxation and positive pressure ventilation, often using total intravenous anesthesia.
  • Airway management depends on stent type and location.
  • Intubating patients' tracheas with a tracheal stent requires special caution, as it risks damaging tissue and dislodging the stent distally.
  • Potential complications with removal include tracheal disruption, retained stent pieces, mucosal tears, re-obstruction requiring new stent placement, the need for postoperative ventilation, pneumothorax, damage to the pulmonary artery, and death.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVE: To evaluate the indications, techniques, outcomes and complications of metallic stent removals in patients with airway disorders.
  • The airway stent retrieval was performed under the guidance of rigid or flexible bronchoscopy between November 2005 and November 2009.
  • Excessive stent-related granuloma formation or recurrent tumor in patients with UCMS group was similar to those with CMS (94.4% vs 89.7%).
  • 87.0% (20/23) Z-type CMS was removed with a retrieval hook by a flexible bronchoscopy under local anesthesia with an average duration of pre-removal stenting of (3.5 +/- 0.6) months while 80% (12/15) Nitinol UCMS removed by a rigid bronchoscopy under general anesthesia with an average duration of pre-removal stenting of (10.7 +/- 3.7) months.
  • A successful retrieval of intact stents was achieved in 84.0% (21/25) of CMS while 92.3% (12/13) of UCMS had a retrieval of rupture stent or piecemeal.
  • In all cases, major post-removal complications included profuse hemorrhage (n = 4) and mucosal tear (n = 15).
  • CONCLUSIONS: The indications for endoscopic retrieval of metallic stents include excessive or recurrent granuloma formation or tumor, recurrence of stenosis after stenting, stent fracture and conclusion of treatment, 3 - 4 months post-stenting in patients with benign stenoses.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • We have provided general anesthesia for a 53-year-old man scheduled to undergo lymph node removal for right mediastinal lymph node metastases caused by esophageal cancer.
  • One year prior, acute respiratory failure occurred because of stenosis of the carinal bifurcation resulting from advanced esophageal cancer with tracheal invasion.
  • The patient underwent placement of tracheobronchial stents (Spiral Z Stent) in two locations (left main bronchus and trachea/right main bronchus), followed by radiotherapy and chemotherapy.
  • In the present case, after an 8.5-mm-ID tracheal tube was placed under bronchoscopic guidance, a 7.0 Fr. bronchial blocker (Arndt Endobronchial Blocker; Cook, Bloomington, IN, USA) was carefully inserted into the stent in the right main bronchus.
  • We confirmed there was no tracheobronchial injury nor stent displacement or deformation, then removed the tracheal tube.
  • Even in patients with tracheobronchial stent placement, one-lung ventilation can be safely and reliably performed by selecting an appropriate bronchial blocker, along with careful insertion into the stent and frequent checking of the blocker position.

  • First case was a 39 year-old female who had 5 cms tracheal and 2 cms left main bronchial stenosis from previous endobronchial tuberculosis.
  • After 36 procedures of tracheobronchial dilatation by rigid bronchoscopy and two tracheal stents placement, her trachea became restenosis in an average time of 1 month.
  • The second case was a 18 year-old male who had 4 cms tracheal stenosis result from post intubation.
  • After 1 year the tracheal stent was removed and rapid restenosis of the trachea resulted in respiratory failure occurred in 7 days.
  • The tracheal stent was reimplanted and 1 year later 7.0 Gy HDR brachytherapy was done after stent removal.
  • He was doing well 4 months after with 50% tracheal stenosis and occasional stridor.
  • Conclusion: Failure of intervention bronchoscopic techniques in management of BCTS was significantly shown by the restenosis even after endobronchial stent placement.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Therefore, we performed a prospective study to evaluate the clinical efficacy of a fully covered, retrievable self-expanding metal stent (Niti-S).
  • METHOD: Between October 1998 and February 2009, 100 consecutive patients with malignant esophageal obstruction treated with the fully covered Niti-S stent (Niti-S, Taewoong Medical, Seoul, South Korea) were included.
  • Data collected contained functional outcome, feasibility of endoscopic stent retrieval, recurrent dysphagia, complications, and survival.
  • RESULT: At 4 weeks after stent placement, dysphagia significantly improved in all patients (p = 0.000).
  • Recurrent dysphagia occurred in 19 of 100 patients treated with Niti-S stents (19%) mainly due to tumor overgrowth (7/100, 7%), stent migration (6/100, 6%), and food impaction (6/100, 6%).
  • Endoscopic stent retrieval was successful in all the attempted 17 patients (17/100, 17%)--7 overgrowth, 6 stent migration, 2 stent degradation, and 2 severe pain.
  • Major complications were 2 hemorrhage, 2 severe pain, and 1 tracheal compression (5/100, 5%), and minor complications were 10 retrosternal pain and 7 symptomatic gastroesophageal reflux (17/100, 17%).
  • There was no stent-related mortality or 30-day mortality.
  • CONCLUSION: The fully covered, retrievable Niti-S stent has proved its effectiveness for palliation of malignant dysphagia and feasibility of endoscopic retrieval.

  • The use of endobronchial stents has rapidly increased since the first airway stent was developed in the 1960s and with the subsequent manufacture of improved silicone and metallic stents.
  • They provide effective relief for symptoms of intrinsic and extrinsic airway obstruction secondary to a wide range of pathologies including lung cancer, lymphoma, thyroid carcinoma and benign disease such as tracheal strictures and tracheobronchomalacia.
  • Endobronchial stents can also seal defects within the airway including malignant broncho-oesophageal fistulae and posterior wall tracheal tears.
  • Complications of endobronchial stents include infection, granulation tissue formation and metallic stent fracture sometimes requiring removal, although serious life-threatening complications are very rare.

  • All but one stent were successfully placed.
  • The others were diagnosed with metastatic disease prior to surgery, had disease progression in spite of neoadjuvant treatment, or died with the stent in place.
  • Three patients developed delayed complications: recurrent dysphagia (n= 2) and tracheal-esophageal fistula (n= 1).
  • Eight (73%) stents were subsequently removed, one because of complication (tracheal-esophageal fistula), one because of migration (recurrent dysphagia), one was incorrectly deployed, and five were felt to have satisfied their purpose.
  • Removal was characterized as very easy in all cases.
  • Upon removal, ulcerations at the proximal or distal edge of stents were noted in six patients (75%), polyps in four (50%), and granulation in six (75%).
  • One stent (13%) became embedded but was easily lifted from tissue.

  • In response to the recent success of tracheal replacement by fresh allogenic aorta in humans, we assessed in a pig model the feasibility of circumferential segmental esophageal replacement by a fresh aortic allograft.
  • When stenosis occurred after stent removal or migration, a new stent was inserted.
  • Four animals died from stent migration during the entire follow-up.
  • Maintenance of a lumen through the graft area by a stent was necessary for 6 months, in order to avoid stenosis occurrence.
  • CONCLUSION: Short esophageal replacement by fresh aortic allograft, under the cover of a temporary maintenance of the lumen of the graft area by an esophageal stent, allows the restitution of a patent esophageal lumen and nutritional autonomy.

  • METHODS: The open Aboulker Teflon stent versus the cut, closed, soft Silastic Montgomery T-tube stent for short-term stenting in double-stage laryngotracheoplasty (dsLTP) were compared.
  • RESULTS: Twenty-four patients were recruited into the study; 12 received an Aboulker (A) stent and 12 a cut, soft, Silastic (S) stent.
  • There was no statistically significant difference in the operation specific decannulation rate between the two stent groups.
  • Furthermore, those receiving S stents had increased need for airway dilation after stent removal (1.75 vs. 0.17 dilations per patient, P = .02) and increased presence of granulation tissue in the airway at the time of stent removal.
  • Multivariate analysis showed the type of stent used independently correlated to time to decannulate (P = .022).

  • Like most conventional medical implants, they are designed to perform their functions for a limited period of time, after which surgical removal is often required.
  • This work combines microfabrication technology with bioresorbable polymers, with the ultimate goal of a fully biodegradable airway stent ultimately capable of improving patient safety and treatment outcomes.
