Abstract
]Background/Objective］ In our hospital, dental floss-clip traction (DFC) method has been used for gastric endoscopic submucosal dissection (gastric ESD) . We examined the safety and efficacy of the DFC method in gastric ESD. ]Methods］ We retrospectively examined 288 epithelial tumor lesions of the stomach in which gastric ESD was performed during the period May 2012 to December 2014 in our hospital. We conducted a comparative study of the en bloc resection rate, complete resection rate, treatment time, and complication rate between 57 lesions which underwent gastric ESD using DFC method and 231 lesions which underwent gastric ESD without it. ]Results］ The background data of patients in both groups were comparable. Only the mean treatment time of the DFC group (mean±standard deviation ]SD］, 81.6±78.4 min) was significantly shorter than that of the non-DFC group (mean±SD, 97.3±68.1 min) (p＝0.020) . ]Conclusion］ DFC method is effective for improving the technical difficulty of gastric ESD.
