STER maintains the integrity of digestive tract mucosa through establishing a tunnel between mucosa and MP which enables resection of SMTs. This chapter introduces the procedures in different parts of gastrointestinal tract, preoperative preparation and postoperative treatment, related complications and treatment, and efficacy of STER.
