Endoscopic full-thickness resection of an esophageal gastrointestinal stromal tumor without creation of a submucosal tunnel

Gastrointestinal stromal tumors (GISTs) are rare in the esophagus, accounting for less than 2% of all cases [1]. While treatment approaches remain under discussion, submucosal tunneling endoscopic resection has shown favorable outcomes [2]. However, in the narrow submucosal space, locating the tumor without exposing its surface can be difficult, increasing the risk of capsule injury and tumor seeding. Here, we report a successful case of GIST resection using direct muscle layer incision without creating a submucosal tunnel.
