Feasibility of a Modified SCC Method With and Without Combining the Use of PGA Sheets and Fibrin Glue for Preventing Delayed Bleeding After Gastric ESD

Abstract Background: Some methods have been developed for preventing delayed bleeding (DB) after gastric endoscopic submucosal dissection (GESD). However, none of the methods can completely prevent DB. We hypothesized that DB can be prevented by a modified the search, coagulation, and clipping (MSCC) method for patients at low risk of DB and by combining the use of PGA sheets and fibrin glue with the MSCC method (PMSCC method) for patients at high risk of DB (anti-bleeding [ABI] strategy). In this study, the technical feasibility of this novel strategy was assessed.Methods: We investigated 123 lesions in 121 consecutive patients who underwent GESD in Kushiro Rosai Hospital between April 2018 and January 2020. The decision for continuation or cessation of antithrombotic agents was based on the Guidelines for Gastroenterological Endoscopy in Patients Undergoing Antithrombotic Treatment.Results: Oral antithrombotic agents were administered to 28 patients (22.8%). En bloc R0 resection rate was 98.4%. The MSCC method and PMSCC method for preventing were performed in 114 and 9 lesions, respectively. The median time of the MSCC method was 16 min and the median speed was 3.6 cm2/10min. The median time of the PMSCC method was 59 min and the median speed was 1.3 cm2/10min. The only delayed procedural adverse event was DB in one (0.8%) of the 123 lesions. Conclusions: The ABI strategy is feasible for preventing DB in patients at low risk and high risk of DB after GESD, whereas the PMSCC method may be necessary for reduction of time.
