Abstract
BACKGROUND Expiratory central airway collapse (ECAC) following postintubation airway stenosis (PITS) is a rare phenomenon. The impact of airway malacia and collapse on the prognosis and the success rate of bronchoscopic interventional therapy in patients with PITS had been inadequately investigated. OBJECTIVE The aim of this research was to assess the influence of airway malacia and collapse on the efficacy of bronchoscopic interventional therapy in patients with PITS. DESIGN This retrospective analysis examined the medical documentation of individuals diagnosed with PITS who underwent bronchoscopic intervention at the tertiary interventional pulmonology center of Emergency General Hospital from 2014 to 2021. MAIN OUTCOME MEASURES Data pertaining to preoperative, perioperative, and postoperative stages were documented and subjected to analysis. RESULTS The patients in malacia and collapse group (MC group) exhibited a higher frequency of perioperative complications, including intraoperative hypoxemia, need for reoperation within 24 h, and postoperative intensive care unit admission rate (P < 0.05, respectively). Meanwhile, patients in group MC demonstrated significantly worse postoperative scores (higher mMRC score and lower KPS score) compared to those in pure stenosis group (P < 0.05, respectively), along with higher degrees of stenosis after treatment and a lower success rate of bronchoscopic intervention therapy cured (P < 0.05, respectively). Pearson analysis results showed that these terms were all significantly correlated with the occurrence of airway malacia and collapse in the airway (P < 0.05, respectively). CONCLUSION The presence of malacia or collapse in patients with PITS was associated with increased perioperative complications following bronchoscopic interventional therapy, and significantly reduced the long-term cure rate compared to patients with pure tracheal stenosis.

Bibas BJ, Minamoto H, Cardoso PFG, Cremonese MR, Pêgo-Fernandes PM, Terra RM. Brazilian airway surgery survey indicates low overall numbers and need for improved teaching skills. INTERDISCIPLINARY CARDIOVASCULAR AND THORACIC SURGERY 2024; 38:ivad177. [PMID: 37950507 PMCID: PMC10858343 DOI: 10.1093/icvts/ivad177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 10/30/2023] [Accepted: 11/06/2023] [Indexed: 11/12/2023]
Abstract
OBJECTIVES The Brazilian Society of Thoracic Surgeons conducted an online survey to determine the number of surgeons that perform adult and paediatric airway surgery and to understand the practice patterns along the country. METHODS Active members were electronically invited to complete the questionnaire through the REDCapR platform. Invitations were sent from January to April 2020. The survey encompassed 40 questions that explored 4 different topics in the assessment of tracheal diseases: (i) surgeon's demography; (ii) institutional profile, (iii) education and training in laryngo-tracheal surgery and (iv) preoperative and postoperative evaluation. RESULTS Eighty-nine percentage of the responders declared to perform tracheal surgery with a median of 5 tracheal resection procedures per year [interquartile range (IQR) 3-12]. Interaction with other specialties occurs in 37.3% of cases. Access to technology and devices is highly variable across the country. Resident training in airway surgery consists in traditional lectures in 97% of the cases. Training in animals (15.2%), cadavers (12.1%) and simulators (6.1%) are rare. Preoperatory evaluation encompasses flexible bronchoscopy (97.8%) and/or computed tomography (CT) scan of the airways (90.6%). Swallowing (20.1%) and voice (14.4%) disorders are rarely evaluated. Eighty-nine percentage of the surgeons consider bronchoscopy to be the preoperatory gold-standard exam, followed by CT scan (38.8%) and CT-3D reconstruction (37.4%). CONCLUSIONS Brazilian surgeons refer that airway resection and reconstruction are part of their current practice, but the total number of procedures per surgeon per year is low. Access to high-end technology and equipment is heterogenous. Training offered to residents in most academic institutions relies on traditional lectures.

Abstract
Tracheitis sicca is a rare condition where there is drying and crusting of tracheal mucosa which may lead to tracheal obstruction and respiratory distress. Reported here is a case of young boy, who presented with cough, cold and respiratory distress worsening over a period of 5 days. On admission the patient was administered with dexamethasone and was intubated. However, saturation was not maintained despite assisted ventilation, and multiple episodes of self extubation always presented with stridor. Hence, otorhinolaryngology reference was taken and decision was taken to perform laryngotracheobronchoscopy. Endoscopy done showed extensive crusting in the trachea causing complete obstruction of airway above the level of carina. The crusting was meticulously removed, sent for culture, and the obstruction was relieved. The patient maintained saturation after the procedure, and was ultimately extubated and discharged.

Abstract
BACKGROUND Tracheal stenosis (TS) is a complication of prolonged intubation, tracheotomy, and tracheal surgery that compromises the vascular supply. Animal models are essential for studying its pathophysiology and the effect of interventions. OBJECTIVE To establish a TS model in rats secondary to tracheal autotransplantation with a graft submerged in bleomycin (Atx-Bleo). Additionally, to evaluate the clinical and histological changes, as well as the expression of newly formed collagen (NFC), isoforms of transforming growth factor beta (TGFβ), fibronectin (FN), elastin (ELN), integrin β1 (ITGβ1), and matrix metalloproteinase 1 (MMP1) in TS. METHODS Twenty Wistar rats were divided into three groups: group I (n = 20) control; group II (n = 10) end-to-end anastomosis of the trachea (tracheoplasty); and group III (n = 10) Atx-Bleo. The animals were evaluated clinically, tomographically, macroscopically, morphometrically, and microscopically. NFC deposition, and the expression of profibrotic and antifibrotic proteins were evaluated in tracheal scars. RESULTS All animals survived the surgical procedure and the study period. Compared with the other study groups, the Atx-Bleo group developed TS and fibrosis, exhibited higher expression of NFC, TGFβ1, TGFβ2, FN, ELN, and ITGβ1, and mild expression of TGFβ3 and MMP1 (p < 0.005; analysis of variance, Dunnett and Tukey tests). CONCLUSION Atx-Bleo in TS model rats produces tomographic and histological changes, and induces the upregulation of profibrotic proteins (TGFβ1, TGFβ2, collagen, FN, ELN, ITGβ1) and downregulation of antifibrotic proteins (TGFβ3, MMP1). Therefore, this model may be used to test new pharmacological treatments for reversing or preventing TS, and conduct basic studies regarding its pathophysiology.

Abstract
BACKGROUND Subcutaneous emphysema (SCE) is a common occurrence in emergency veterinary practice, but published information regarding treatment and management strategies is lacking. This study examined trends in diagnostic and treatment recommendations. STUDY DESIGN An internet-based survey with cross-sectional analysis. There were 129 respondents: board-certified and nonboard-certified veterinarians in private practice and university settings. KEY FINDINGS Significant differences in the choice of diagnostics and treatment were found based on the etiology and severity of SCE and between respondent groups. Computed tomography (CT) was selected more frequently for SCE resulting from blunt or penetrating traumas by the board-certified veterinarians practicing in a teaching hospital (VTH group; P < 0.001). All veterinarians were more likely to select tracheobronchoscopy as part of their workup for SCE as a result of endotracheal intubation trauma (P = 0.0093 [penetrating traumas]; P = 0.0002 [blunt force traumas]). Intermittent SC drainage and ventral cervical exploratory surgery were more likely to be chosen as treatments when SCE was classified as severe generalized (P < 0.0001). SIGNIFICANCE There is significant variation in the treatment of SCE in veterinary medicine as well as associated diagnostics to determine severity and treatment options. Further studies are indicated to determine the optimal approach and provide guidance to clinicians.

Abstract
BACKGROUND AND AIM Post-intubation tracheal stenosis (PITS) is an iatrogenic injury that involves some patients. Given the importance of this issue and the referral of a significant number of children with tracheal stenosis to Masih Daneshvari Hospital in Tehran, Iran, the present study investigated tracheal stenosis following prolonged intubation in the pediatric age group. METHODS In this observational retrospective study, from 1994 to 2018, the medical records of all children under 14 years of age with a history of PITS were reviewed. Demographic and clinical characteristics including signs and symptoms, the underlying condition that leads to intubation, duration of intubation, type of stenosis, and the therapeutic approach, type of surgery, and follow-up were collected and analyzed using SPSS. RESULTS Among 161 patients with a mean age of 9.8 ± 4.2 years, 69% were male. The site of stenosis was limited to the trachea in 47% and others both trachea and subglottic area were involved. The most common cause of intubation was trauma. The most common symptoms were dyspnea and wheezing. Success rates of reconstruction were 93.75% in type I, 82.15% in type II, and 35.70% in type III. Among the 16 patients who underwent Type III surgery, decannulation was not performed in 11 patients. Traction in the anastomosis and complications were stated in 26 and 10% of the patients respectively, a mortality rate of 8.7% was also reported. CONCLUSION In the case of endotracheal intubation, PITS should be considered in the differential diagnosis of dyspnea in children as well as adults.
