Submucosal tunneling endoscopic resection of a gastroesophageal junction leiomyoma: Report of a case

Abstract

Introduction: Upper gastrointestinal submucosal tumors are potentially malignant lesions; so safe and efficient treatments are needed. In recent years, submucosal tunneling endoscopic resection (STER) has emerged as a novel therapeutic technique, with promising results. Case report: 47-year-old male patient, previously asymptomatic, who was found to have a subepithelial lesion at the gastroesophageal junction. Upper endoscopic ultrasound was compatible with a leiomyoma. He underwent STER to remove the tumor and recovered with any complications. The biopsy confirmed an esophageal leiomyoma. Discussion: STER has become a highly feasible and safe therapeutic option for submucosal tumors of the gastroesophageal junction. The challenge is to spread knowledge about this technique, to maximize patient’s benefit.
