An 83-year-old woman presented complaining of malaise, poor appetite and vomiting. After upper gastrointestinal endoscopy revealed severe stenosis in the lower esophagus, she was admitted for further investigation and treatment. Whole-body examination detected no malignant findings. A diagnosis of benign esophageal stenosis due to repeated reflux esophagitis was made. A total of 14 regularly scheduled endoscopic balloon dilations were performed at the stenotic site, but no improvement of the stenosis was seen. Therefore ablation was performed on three areas of the stenotic lesion, using microwave coagulation. This resulted in improvement of the stenosis and accompanying symptoms.
