Abstract:
Objective:To evaluate the feasibility and effectiveness of magnetic anchor-guided endoscopic submucosal dissection (MAG-ESD).Methods:A total of 36 patients with gastrointestinal tumors at different sites who underwent MAG-ESD in the First Affiliated Hospital of Xi'an Jiaotong University from March 2020 to October 2022 were enrolled. The anchor success rate, en bloc resection rate, the anchor time, the procedure time, and the complication incidence were observed and analyzed.Results:Among the 36 patients, there were 9 lesions in stomach, 2 in duodenum, 6 in cecum and 19 in colorectum. Thirty-five (97.2%) patients successfully underwent magnetic anchor, and en bloc resection of lesions were completed. No adverse events such as bleeding or perforation occurred. The anchor time and procedure time was 4.0 (2.0-9.5) min and 36 (16-82) min, respectively.Conclusion:MAG-ESD is feasible and effective for gastrointestinal tumors at different sites, with a high anchor success rate and en bloc resection rate, and shorter operation time, especially for difficult submucosal dissection.
