Background:At present,the detection rate of esophageal leiomyoma is increasing year by year,among which giant esophageal leiomyoma(GEL)can be caused by secondary compression,malignant and even death.The safety and effectiveness of submucosal tunnel endoscopic resection(STER)in the treatment of GEL need to be further verified.Aims:To assess the safety and efficacy of STER in the treatment of GEL.Methods:Fifteen patients who underwent endoscopic ultrasound and STER surgery from June 2020 to June 2023 at General Hospital of Xinjiang Military Region,and postoperative pathological biopsy confirmed GEL to assess the efficacy,complications,tumor recurrence and follow-up.Results:In 15 patients with GEL,8 were male and 7 female;GEL was completely resected and the margin was clean;the maximum tumor diameter was 8.5 cm;mean operation time of 52 minutes;fewer adverse events and no delayed bleeding;all underwent conservative treatment;mean hospital stay of 6 days;and no discomfort and recurrence in the postoperative follow-up.Conclusions:STER is safe and effective in the treatment of GEL.
