A Case of Two-stage Treatment for Membranous Stenosis of the Esophagus Complicated by an Aberrant Right Subclavian Artery and Kommerell’s Diverticulum

Abstract

A 39-year-old man complained of repeated nausea and vomiting after eating. Computed tomography showed that the esophagus was compressed between the trachea and the aberrant right subclavian artery and Kommerell’s diverticulum. Additionally, upper gastrointestinal endoscopy showed membranous stenosis in the mid-esophagus. Surgical intervention was carried out through a median sternotomy approach, involving the excision of Kommerell’s diverticulum and reconstruction of the right subclavian artery. Approximately 3 months later, esophageal dilation was performed for the remaining membranous stenosis using an esophageal bougie in three sessions with the bougie size gradually increasing at 1.5 month intervals. This procedure resulted in expansion of the stenotic area and improvement of the esophageal passage obstruction.
