Diagnosis Of Esophageal Stenosis Research Articles

Esophageal stenosis (ES) is characterized by dysphagia, failure to thrive, and long-term disability. It requires repeated management because it is refractory. Traditionally, these procedures are performed under general anesthesia with airway intubation. This study investigated the safety and efficacy of the management of interventional flexible endoscopy (IFE) performed with a novel noninvasive ventilation (NIV) support. Use of a short-length flexible endoscope with NIV of pharyngeal oxygen, nose closure, and abdominal compression during IFE was investigated. Medical charts of patients aged ≤10 years with a diagnosis of ES in our hospital between 1990 and 2014 were reviewed and analyzed. The outcome measurement included the number of IFE with balloon dilatation (BD), laser therapy (LT), stent placement, procedural complications, and the success rate. Ten patients were enrolled. The most common etiologies were esophageal atresia with/without tracheoesophageal fistula (n=6), followed by caustic injury (n=2), and unknown etiology (n=2). Nine patients who were considered successfully managed received an average of 2.8 BD sessions and 1.6 LT sessions. The complication rate of IFE in this study was 1.08% (1/93). One esophageal perforation developed after BD (1/63) and none after LT (0/30). In this study, IFE with this NIV support is a safe, feasible and valuable modality which could rapidly examine and manage ES.
