Abstract:Objective To research the safety and efficacy of endoscopic rapid resection (ERR) for small gastric submucosal tumor (SMT).Method The surgical data and clinical outcomes of 133 patients with small gastric SMT underwent ERR from January 2020 to December 2023 were retrospectively analyzed.Result All the 133 patients completed endoscopic treatment in the same period. A patient underwent active full-thickness resection during operation, requiring hospitalization for conservative treatment and fasting. Small perforation occurred in seventeen patients and they were transferred to day ward for observation. 115 patients completed the operation in the outpatient department, and the wound closure was reliable.Conclusion ERR is fast, safe, effective and practical for small gastric SMT. It can be used as the first choice for endoscopic therapy.
