Abstract

Background and study aims Submucosal tunneling endoscopic resection with double opening (DO-STER) was developed by our group for the resection of submucosal tumors in the esophagus and gastric fundus near the cardia. This study aimed to provide a preliminary evaluation of feasibility and safety of DO-STER.

Methods The key to DO-STER is the creation of a tunnel opening in the mucosa over the inferior border of the tumor. During resection, the tumor can be gradually pushed out of the submucosal tunnel through the opening, leaving enough space for operation within the tunnel. A total of 10 tumors resected by DO-STER were retrospectively reviewed.

Results All tumors were successfully resected by DO-STER. One tumor was located at the lower esophagus, four at the esophagogastric junction, and five at the gastric fundus near the cardia. Tumor size ranged from 1.0 × 1.2 cm to 3.5 × 5.0 cm, and all tumors originated from the muscularis propria. Operative times ranged from 45 to 150 minutes. No delayed bleeding or perforation occurred.

Conclusion DO-STER seems to provide an alternative approach for resection of tumors in the esophagus and gastric fundus near the cardia.
