Surgical resection is the mainstay treatment for resectable gastrointestinal stromal tumors (GISTs). However, resection in anatomically challenging locations, such as near the gastroesophageal junction, lesser curve and fundus, remain technically challenging. We herein report the outcomes of the largest series of patients who underwent single-incision transgastric resection of an intraluminal gastric GIST. Our reduced-port resection technique for intraluminal GISTs in these anatomically challenging locations involves a single incision in the left hypochondrium, deepened to access the gastric lumen, with the surgery completed in a transgastric manner...
