Esophageal submucosal tumors are uncommon but clinically significant lesions that may present with symptoms such as dysphagia or may be detected incidentally during upper gastrointestinal evaluation. Traditionally, these lesions were managed surgically. However, advancements in therapeutic gastrointestinal endoscopy have enabled effective minimally invasive alternatives, reducing patient morbidity while maintaining excellent clinical outcomes. Submucosal Tunneling Endoscopic Resection (STER) is one such advanced technique that has expanded the scope of interventional gastroenterology in managing selected esophageal submucosal tumors.
Overview of the STER Procedure
Patients with esophageal submucosal tumors commonly present with intermittent dysphagia, particularly for solid foods, depending on lesion size and location. In this clinical case, upper gastrointestinal endoscopy revealed a submucosal soft-tissue lesion in the mid-esophagus, associated with luminal narrowing and intact overlying mucosa. These findings supported further evaluation and suitability for endoscopic management.
Clinical Advantages of STER
Submucosal Tunneling Endoscopic Resection (STER) is a minimally invasive therapeutic endoscopic technique developed for the resection of submucosal tumors arising from the muscularis propria. The procedure involves the creation of a submucosal tunnel, controlled access to the lesion, en bloc resection of the tumor, and preservation of mucosal integrity to reduce the risk of perforation. STER is particularly effective for selected cases of esophageal leiomyoma and similar submucosal lesions when performed by experienced endoscopists.

Compared with conventional surgical approaches, STER offers several advantages. It is a completely endoscope-based, minimally invasive technique that avoids open or thoracoscopic surgery, preserves esophageal wall structure, and reduces procedural morbidity. Patients benefit from faster post-procedure recovery and shorter hospital stays in suitable cases. Successful outcomes depend on appropriate patient selection, lesion characteristics, and advanced endoscopic expertise.
A clinical procedure video demonstrating Submucosal Tunneling Endoscopic Resection (STER) for a mid-esophageal submucosal lesion has been posted on MedTube, an international medical platform dedicated to gastrointestinal endoscopy education and professional training. This video serves as an educational resource for gastroenterologists and endoscopy trainees, supporting procedural learning and knowledge exchange in interventional gastroenterology.

STER represents a significant advancement in the management of selected esophageal submucosal tumors, offering a safe and effective alternative to surgery. With careful evaluation and expert execution, minimally invasive endoscopic techniques can significantly improve patient outcomes and recovery.
