Submucosal tunneling endoscopic resection in retroflexion for gastric GIST of the fundus

Abstract Text Endoscopic resection of gastrointestinal gastric tumors of the fundus is challenging due to the need for full-thickness resection and the difficulties for defect closure. Submucosal tunneling in direct view through the esophagus can be applied for esophageal tumors and gastric tumors of the cardia near the gastroesophageal junction. However for tumors located at the fundus it is not feasible. In this case report we present the resection of a gastric GIST located at the fundus with the application of STER in retroflexion combined with clip and band traction and clip and loop closure of the mucosal entrance. We believe that this modified approach has the all the advantages of STER and can be applied for locations where straight tunneling is not feasible.
