RESUMO

BACKGROUND: The permanent placement of metallic stent for benign tracheobronchial stenosis (BTS) was controversial. This study was conducted to evaluate the long-term outcomes of temporary placement of metallic stent for BTS. METHODS: The BTS patients who received temporary placement of retrievable self-expanded metallic stents were included between 2008 and 2011. Pre-stenting and follow-up respiratory status was analyzed. And symptom recurrence-free survival (SRFS) was assessed. RESULTS: A total of 49 stents were successfully temporarily placed in 40 consecutive BTS patients whose etiologies included endobronchial tuberculosis (EBTB) (n=22), post-tracheostomy stenosis (n=10), post-intubation stenosis (n=6) and post radiotherapy stricture (n=2). All stents were removed integrally after a median 18 days' stenting period, without major complications. During the median 27 months follow-up period after stent removal, a total of 22 patients were free of recurrence. And the overall 3-year SRFS rate was 52.0%. According to the etiology, the 3-year SRFS rates were 59.1% and 42.9% in the patients with EBTB and non-EBTB, respectively. Compared with pre-stenting, the follow-up internal diameter of stricture, Hugh-Jones scale, 6-minute walk test (6MWT) and percentage of forced expiratory volume in one second (FEV1%) were significantly improved. Multivariate analysis suggested that granulation tissue growth and tracheobronchial malacia might be independent factors of poor prognosis. CONCLUSIONS: Temporary placement of retrievable metallic stent may be an alternative treatment for BTS patients.

RESUMO

BACKGROUND AND STUDY AIMS: Tracheobronchopathia osteochondroplastica (TO) is an uncommon disease of the tracheobronchial system that leads to narrowing of the airway lumen from cartilaginous and/or osseous submucosal nodules. The aim of this study is to perform a detailed review of this rare disease in a large cohort of patients with TO proven by fiberoptic bronchoscopy from China. PATIENTS AND METHODS: Retrospective chart review was performed on 41,600 patients who underwent bronchoscopy in the Department of Respiratory Medicine of Changhai Hospital between January 2005 and December 2012. Cases of TO were identified based on characteristic features during bronchoscopic examination. RESULTS: 22 cases of bronchoscopic TO were identified. Among whom one-half were male and the mean age was 47.45±10.91 years old. The most frequent symptoms at presentation were chronic cough (n = 14) and increased sputum production (n = 10). Radiographic abnormalities were observed in 3/18 patients and findings on computed tomography consistent with TO such as beaded intraluminal calcifications and/or increased luminal thickenings were observed in 18/22 patients. Patients were classified into the following categories based on the severity of bronchoscopic findings: Stage I (n = 2), Stage II (n = 6) and Stage III (n = 14). The result that bronchoscopic improvement was observed in 2 patients administered with inhaled corticosteroids suggested that resolution of this disease is possible. CONCLUSIONS: TO is a benign disease with slow progression, which could be roughly divided into 3 stages on the basis of the characteristic endoscopic features and histopathologic findings. Chronic inflammation was thought to be more important than the other existing plausible hypotheses in the course of TO. Inhaled corticosteroids might have some impact on patients at Stage I/II.

RESUMO

OBJECTIVE: Tracheobronchial foreign bodies (FBs) are frequently present in adults. This study reports our experience with the managements of FB and FB-related complications using flexible bronchoscopy. METHODS: We retrospectively reviewed the adult patients with FBs treated between 2001 and 2011 in China. The demographic and endoscopic data were collected and analyzed. RESULTS: A total of 200 adult patients (136 men and 64 women) with an average age of 51 years were analyzed. The most common FBs included bones (51.0%), nut shells (15.0%), food boluses (7.0%), plastic toys or pen caps (6.5%). After FB aspiration occurred, only 11.0% were diagnosed within three days, while more than half of the patients (58.0%) delayed the diagnosis by more than one month. The incidence of FB-related complications was 79.5%, including granulation formation (76.5%), obstructive pneumonia (22.0%), hemorrhage (14.5%), atelectasis (10.0%) and endobronchial stenotic scarring (8.0%). In 96.5% of the patients, the FBs were successfully removed under flexible bronchoscopy. A total of 53 out of the 153 patients with granulation (34.6%) were managed by argon plasma coagulation (APC) or cryotherapy; two out of the sixteen patients with endobronchial stenotic scars were treated by balloon dilation under flexible bronchoscopy. CONCLUSION: A high incidence of FB-related complications occurs, likely as a result of the long delay between aspiration and diagnosis, a proportion of which require endoscopic intervention. The removal of FBs under flexible bronchoscopy has a high success rate and therefore should be recommended for adults.
