Objective: The aim of this study is to evaluate the long-term outcomes of a large series of patients treated with submucosal tunneling endoscopic resection (STER).

Background: STER is a newly developed treatment for upper gastrointestinal submucosal tumors originating from the muscularis propria layer. Recently, reports about STER are increasing, but a large study with long-term follow-up is little known.

Conclusions: STER is an effective and safe methodology for the resection of upper gastrointestinal submucosal tumors. Tumor size and shape impact on the piecemeal resection rate and procedural difficulty. STER for large tumors with irregular shape in the deep muscularis propria is also feasible but associated with relatively high risks of piecemeal resection and complications.
