Core Tip

Core tip: Submucosal tunneling and endoscopic resection (STER) has emerged as a new technique for resecting upper gastrointestinal subepithelial tumors (SETs). This new endoscopic technique has advantages over conventional endoscopic muscularis excavation in terms of maintaining the integrity of the digestive tract mucosa and submucosa, promoting rapid wound healing, and reducing the risk of pleural/abdominal infection. The present study was conducted to evaluate the safety and efficacy of STER for SETs at the esophagogastric junction originating from the muscularis propria layer.
