Snare and rubber band combined assisted traction：a novel method for endoscopic submucosal dissection in treating early gastric cancer

Abstract Background: Endoscopic submucosal dissection（ESD）has the advantages of high complete resection rate, less trauma and higher safety than open surgery. However, ESD has high technical requirements and is difficult to operate, especially when submucosal dissection fails to fully expose the submucosa. To create a good operational field of vision and achieve accurate cutting, a variety of endoscopic assisted traction methods have emerged. Our study team has invented a new traction method, that is, snare combined with rubber band assisted ESD in the treatment of early gastric cancer. Methods: Retrospective study was performed in 41 patients diagnosed as having early gastric cancer and received ESD assisted by snare and rubber band method from January 2020 to June 2022.The en bloc excision rate, procedure time, complication rate were analyzed. Results: All lesions received en bloc resection. The lesion size ranged 2~6cm.The median procedure time was 29min (ranging 23~44min). There was no bleeding or perforation occurred during and after the procedure. Conclusion: Snare-rubber band assisted traction method can provide good vision during the ESD procedure for early gastric cancer, and increase resection efficiency, reduce the operation time and complication rate.
