Abstract

Esophageal leiomyomas are benign tumors of the smooth muscle. They are usually asymptomatic, but when large, they may cause symptoms such as dysphagia, chest pain, or weight loss, which may require treatment. Managing these complex tumors, especially in cases with an annular or horseshoe-shaped morphology, presents challenges due to the restricted surgical field during endoscopic resection, because the esophagus has a narrow lumen. We report three cases of horseshoe-shaped esophageal leiomyomas that were treated using the underwater submucosal tunneling endoscopic resection (U-STER) technique combined with partial myotomy due to adherence to the muscularis propria in one case. All tumors were successfully resected without any complications and all patients recovered rapidly. Histological examination confirmed that all tumors were benign smooth muscle tumors. None showed evidence of recurrence at 1-month follow-up.
