Background: The third-generation fully covered self-expandable metallic stent (SEMS) has been developed to solve the problems of difficult removal and in-stent granuloma formation related to the uncovered or partially covered type. There are few written reports about the performance of this type of stents with early encouraging results. Objectives: To report and analyse our experience with the Silmet® stent in the management of malignant and benign tracheobronchial disorders. Methods: We retrospectively reviewed medical records of patients who underwent fully covered SEMS Silmet placement at the Interventional Pulmonology Unit, La Maddalena Cancer Center, Palermo, Italy, between May 2010 and August 2013. Results: Stents were placed in 52 patients with malignant (n = 49) and benign airway obstruction (n = 2) and broncho-oesophageal fistula (n = 1). SEMSs were inserted into the trachea (n = 19), the main bronchi (n = 21) and the peripheral bronchi (n = 31). Besides 1 procedural dislocation, the deployment was successful in all patients with an immediate significant improvement of symptoms (Barthel Index p < 0.001; Medical Research Council score p < 0.001). A radiographic improvement was detected in 48% of patients. The mean follow-up duration was 119 ± 120 days (range 22-549 days). Complications observed were: migration (7.6%), tumour overgrowth (15%), infections (5.7%), granulation tissue formation (3.8%) and mucus plug (3.8%). Conclusions: The Silmet stent is effective, safe and simple to implant and remove. We suggest its use in cases of tight stenoses, in the treatment of small- to medium-caliber airways or in cases of tortuous airways.

“…A necessidade de treinamento em broncoscopia rígida ou laringoscopia de suspensão para implante e remoção do stent pode representar um obstáculo, visto que uma porção considerável dos médicos que realizam endoscopia respiratória não tem formação em procedimentos com aparelhos rígidos 61 . A despeito de suas vantagens, há relato de caso de hemoptise e dispneia em uma mulher que foi tratada para estenose pós intubação traqueal com esta prótese 65 .

Agradeço a Deus e a meus pais, Roberto Abraham Bibas e Maria Luiza Lopes Bibas por todo amor e pela ajuda, desde sempre (e até hoje). Agradeço a minha mãe pelo amor incondicional e por transmitir para mim valores atemporais: honestidade, trabalho, e educação. Como ela sempre dizia ´´Você pode perder tudo o que ganhou na vida, menos aquilo que aprendeu´´. Não coincidentemente, digo o mesmo hoje para meu filho. Obrigado! Meu pai, exemplo de pai e cirurgião, foi a grande fonte insipradora para seguir na profissão e na especialidade. Cirurgião brilhante e pai excepcional. Me mostrou que a cirurgia tem que ser um procedimento simples, objetivo e prático. Tenho muito orgulho da sua trajetória pessoal e de ser seu filho, e tento aos poucos construir a carreira minha (e vida) para que seja ao menos tão bonita quanto a sua. Je t´embrasse. Dedico esta tese também, em grande parte, à minha esposa Mariana. Após quase 20 anos de convivência, continuamos a desenvolver a nossa relação, que se modifica e melhora cada dia. Crescimento profissional, filho, casa nova, doutorado, projetos multimídia... Os últimos anos foram desafiadores, porém superamos diversos obstáculos com serenidade e tranquilidade. Obrigado pelo apoio, conselhos, suporte, carinho e amor. Te amo cada vez mais! Por último, porém não menos importante, dedico este tese ao meu filho Rui. Hoje, aos 9 anos de idade, percebo traços mais claros de sua individualidade e fico feliz que você se desenvolva com autonomia, garra, personalidade e gênio forte. Sua alegria me contagia e poder ser seu pai é para mim, aprendizado e orgulho diário. Te amo.

Background: Airway stenting has become a common technique in inoperable benign strictures. An ideal stent does not yet exist for these conditions. Recently, fully covered self-expandable metallic stents (SEMS) have been commercialized with potential use in benign airway strictures. Objective: We retrospectively reviewed the clinical effectiveness of fully covered SEMS in the management of benign strictures. Methods: A total of 17 patients received 20 stents: 7 Silmet®, 8 Taewoong® and 5 Alveolus® stents. Ten stents were deployed in a structural postintubation tracheal stenosis. Other indications were multinodular goiter, anastomotic stricture, endobronchial posttuberculosis scar, damaged cartilage and relapsing polychondritis. Results: In our series, the short-term (<12 weeks after stent deployment) complication rate was 75%, requiring stent removal in 60%. Overall, stent migration was observed in 65%, stent fracture in 15%, shriveling of the stent in 10% and granulation formation in 10%. Conclusion: The use of fully covered SEMS for the treatment of benign airway strictures is associated with a high short-term complication rate requiring stent removal. We have abandoned in our clinical practice the use of fully covered SEMS for benign airway strictures.
