Abstract
BACKGROUND AND AIM Current treatments for refractory benign esophageal strictures (BESs) often take several years and have poor effects. The authors propose a novel method of self-help inflatable balloon (SHIB) and evaluate its efficacy and safety. METHODS A prospective, multicenter study was conducted from January 2019 to March 2022. All enrolled patients were diagnosed with refractory BESs and received SHIB. The primary endpoint was the clinical success rate at 12 months after removing SHIB. The secondary endpoints were the number of days of placing SHIB, and changes from baseline in BMI and health-related quality of life at 1, 3, 6, and 12 months. RESULTS The clinical success rate was 51.2% (21/41) with the median days of placing SHIB being 104.0 days (range: 62.0-134.5 days), which was higher in the endoscopic group compared to the caustic and surgery groups (63.3 vs. 28.6% vs. 0, P=0.025). All patients (100%) showed significant improvement in dysphagia scores during placing SHIB. Although 20 patients (48.8%) experienced recurrent stricture, the median stricture length was decreased (P<0.001) and the median intervention-free interval was prolonged (P<0.001). In all patients, the mean BMI at and health-related quality of life at 1, 3, 6, and 12 months were significantly increased compared with baseline (P<0.05). On multivariate analysis, stricture etiology and wearing time were independent predictors of recurrent stricture. CONCLUSIONS The SHIB has high efficacy and safety in treating refractory BESs of different origins, especially for endoscopic resection. Stricture etiology and wearing time were independent predictors of recurrent stricture.

Yang Y, Yang Y, Hou Z, Wang T, Wu P, Shen L, Li P, Zhang K, Yang L, Sun S. Comprehensive review of materials, applications, and future innovations in biodegradable esophageal stents. Front Bioeng Biotechnol 2023; 11:1327517. [PMID: 38125305 PMCID: PMC10731276 DOI: 10.3389/fbioe.2023.1327517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 11/27/2023] [Indexed: 12/23/2023] Open
Abstract
Esophageal stricture (ES) results from benign and malignant conditions, such as uncontrolled gastroesophageal reflux disease (GERD) and esophageal neoplasms. Upper gastrointestinal endoscopy is the preferred diagnostic approach for ES and its underlying causes. Stent insertion using an endoscope is a prevalent method for alleviating or treating ES. Nevertheless, the widely used self-expandable metal stents (SEMS) and self-expandable plastic stents (SEPS) can result in complications such as migration and restenosis. Furthermore, they necessitate secondary extraction in cases of benign esophageal stricture (BES), rendering them unsatisfactory for clinical requirements. Over the past 3 decades, significant attention has been devoted to biodegradable materials, including synthetic polyester polymers and magnesium-based alloys, owing to their exceptional biocompatibility and biodegradability while addressing the challenges associated with recurring procedures after BES resolves. Novel esophageal stents have been developed and are undergoing experimental and clinical trials. Drug-eluting stents (DES) with drug-loading and drug-releasing capabilities are currently a research focal point, offering more efficient and precise ES treatments. Functional innovations have been investigated to optimize stent performance, including unidirectional drug-release and anti-migration features. Emerging manufacturing technologies such as three-dimensional (3D) printing and new biodegradable materials such as hydrogels have also contributed to the innovation of esophageal stents. The ultimate objective of the research and development of these materials is their clinical application in the treatment of ES and other benign conditions and the palliative treatment of malignant esophageal stricture (MES). This review aimed to offer a comprehensive overview of current biodegradable esophageal stent materials and their applications, highlight current research limitations and innovations, and offer insights into future development priorities and directions.
