Abstract
BACKGROUND
With the recent improvement of endoscopic techniques, endoscopic ultrasound-guided fine needle aspiration and endoscopic submucosal tunnel dissection (ESTD) have been widely used for accurate diagnosis and dissection acceleration of esophageal tumors.
CASE SUMMARY
We used a modified submucosal tunnel technique during endoscopic en bloc resection in a 58-year-old man with large esophageal submucosal gland duct adenoma (ESGDA). During modified ESTD, the oral end of the involved mucosa was cut transversely, followed by a submucosal tunnel created from the proximal to the distal end, and the anal end of the involved mucosa blocked by the tumor was incised. As a result of retaining submucosal injection solutions using the submucosal tunnel technique, it was possible to reduce the amount of injection required and increase the efficiency and safety of dissection.
CONCLUSION
Modified ESTD is an effective treatment strategy for large ESGDAs. Single-tunnel ESTD appears to be a time-saving procedure compared with conventional endoscopic submucosal dissection.
