Clinical Study of Airway Stent Implantation in the Treatment of Patients with Malignant Central Airway Obstruction. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:6933793. [PMID: 35990827 PMCID: PMC9385309 DOI: 10.1155/2022/6933793] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 07/12/2022] [Accepted: 07/18/2022] [Indexed: 11/17/2022]
Abstract
Background. Airway stenting is a therapeutic option for malignant central airway obstructions (MCAO), including both intraluminal and extraluminal obstructions. The objective of this study is to investigate the clinical features and results of long-term improved prognosis for MCAO patients after airway stent implantation. Methods. Ninety-eight MCAO patients who underwent stent placement in our hospital from January 2013 to April 2020 were included in this study. The data included baseline data, clinical characteristics, laboratory test data, stent implantation data, and treatment as well as survival after stent implantation. The survival rates among individuals were compared via log-rank tests. Potential prognostic factors were identified using multivariate cox hazard regression models. Results. A retrospective analysis of these patients was generated. MCAO was mainly caused by lung cancer (53/98, 54.08%), esophageal cancer (22/98, 22.45%), and thyroid cancer (3/98, 3.06%). The median survival time of participants was 5.5 months. Univariate analysis indicated that the survival rate was related to primary disease, ECOG PS score, stent site, hemoglobin (Hb), albumin (ALB), and serum lactate dehydrogenase (LDH) (
). The cox risk regression model showed that the survival rate was significantly influenced by ECOG PS score (OR = 3.468, 95%CI = 1.426–8.432,
) and stent site (OR = 1.544, 95%CI = 1.057–2.255,
). Conclusions. Compared with the site of stent placement, the ECOG PS score is the primary factor in the survival rate of MCAO patients after airway stenting.

Interventional therapy via flexible bronchoscopy in the management of foreign body-related occlusive endobronchial granulation tissue formation in children. Pediatr Pulmonol 2021; 56:282-290. [PMID: 33104291 DOI: 10.1002/ppul.25134] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Revised: 10/16/2020] [Accepted: 10/19/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Occlusive granulation tissue formation, as one of the most common sequelae of chronic foreign body aspiration, can cause tracheobronchial obstruction and delayed fixed airway stenosis necessitating interventions. The aim of this study was to explore the clinical efficacy and safety of interventional therapy via flexible bronchoscopy for treatment of granulation tissue related airway obstruction secondary to foreign body aspiration in children. METHOD Patients with long-term foreign body related granulation tissue were treated with flexible bronchoscopy therapeutic modalities, including forceps, cryotherapy, holmium laser, and balloon dilatation. Clinical efficacy was evaluated by clinical symptoms and endoscopic manifestations. RESULTS A total of eight patients with granulation tissue hyperplasia caused by foreign body in bronchus, with a median age of 29.5 (range, 18-54) months, underwent interventional therapy between January 2016 and December 2019. Four patients received forceps and CO2 cryotherapy and one patient required forceps only. The remaining three patients received holmium laser combined with CO2 cryotherapy, and one of them required additional balloon dilatation. Four cases required a second cryotherapy procedure, and one case received three cryotherapy procedures for extensive granulation tissue. The treatment efficacy was 100% without complications. CONCLUSION Interventional procedure via flexible bronchoscopy is a safe, reliable, and effective method in the management of tracheobronchial obstruction and stenosis caused by foreign body-related granulation tissue hyperplasia. It is worthy of clinical application.
