Esophageal scar stenosis

The most common causes of esophageal scar stenosis are chemical burns of the esophagus caused by the swallowing of strong alkalis or strong acids. After healing, the scar tissue contracts and the esophageal lumen is narrow. In addition, gastroesophageal reflux esophagitis forms ulcers and scar contractions. As well as scar scars after esophageal trauma and surgery.
