Submucosal tunneling endoscopic resection for simultaneous esophageal and cardia submucosal tumors originating from the muscularis propria layer (with video).
Submucosal tunneling endoscopic resection (STER) is a new treatment technique for upper gastrointestinal submucosal tumors (SMT) originating from the muscularis propria (MP) layer. In contrast to conventional endoscopic resection, the new therapy can maintain the mucosal integrity of the digestive tract, which effectively prevents mediastinitis and peritonitis. STER, although a known method, has not been widely adopted because of technical difficulties. Here, we describe the case of a 30-year-old patient presenting with two separate SMT originating from the esophageal and cardia MP layer. A 2-cm longitudinal mucosal incision was made approximately 5 cm proximal to the esophageal SMT, and the esophageal and cardia SMT were dissected successively in the same submucosal tunnel. In the relevant literature, this is the first case of STER for resecting esophageal and cardia SMT using the same submucosal tunnel.
