[Novel approach to laparoscopy and endoscopy cooperative surgery (LECS) in gastric submucosal tumors near the esophago-gastric junction].

Background And Purpose: Laparoscopy and endoscopy cooperative surgery (LECS) for gastric submucosal tumors is an excellent surgical procedure that enables prevention of excessive resection and deformity of the stomach. This procedure may be more useful for gastric submucosal tumors near the esophagogastric (EG) junction and the pylorus. We present a novel approach to LECS for gastric submucosal tumors near the EG junction.
