Laparoscopy and endoscopy cooperative surgery (LECS) is widely accepted in Japan for submucosal tumor (SMT) of the gastric cardia and fornix. We modified LECS for SMT of the gastric cardia and fornix by placing supporting sutures at the edge of the remnant gastric wall, making it easier to grasp the remnant gastric wall for the SMT in the cardia. To prevent stenosis because of excessive resection of the esophagogastric junction (EGJ) , we did not perform endoscopic submucosal dissection (ESD) adjacent to EGJ. For the SMT in the gastric fornix, two or three short gastric vessels were divided, and the gastric wall was pulled caudally. These procedures provided a good view of the tumor and adequate tension for ESD.
