Objectives
Narrative objectives1
The incidence of postoperative gastrointestinal bleeding when colon polypectomy is performed on patients taking DOAC in accordance with Gastrointestinal Endoscopy Practice Guidelines supplement for patients taking antithrombotic drugs is expected to be approximately 10%. The risk of bleeding is approximately 10 times greater than in patients not taking DOAC. There are as yet no indicators established for monitoring the efficacy of DOAC, so uniform support is provided for all respective patients, but individualized treatment is provided for patients in the high-risk group when predictive markers that may cause gastrointestinal bleeding are identified, which can contribute to prevention of gastrointestinal bleeding. The aim of this study was to clarify predictive markers that may enable extraction of high-risk groups at risk of postoperative gastrointestinal bleeding, among patients taking DOAC who have undergone an endoscopic colon resection in accordance with the Gastrointestinal Endoscopy Practice Guidelines (supplement 2017) for patients taking antithrombotic drugs
