The incidence of postoperative gastrointestinal bleeding when EST is performed on patients taking DOAC in accordance with Gastrointestinal Endoscopy Practice Guidelines supplement for patients taking antithrombotic drugs is expected to be approximately 8-10%. 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 EST in accordance with the Gastrointestinal Endoscopy Practice Guidelines (supplement 2017) for patients taking antithrombotic drugs.

The effect of DOAC trough drug blood concentration (p-Xa activity) on postoperative gastrointestinal bleeding after EST for common bile duct stone or cancer in patients taking DOAC
(1) The effect of polymorphism of drug-metabolizing enzymes on postoperative bleeding after EST in patients taking DOAC.
(2) The effect of blood coagulation markers on postoperative bleeding after EST in patients taking DOAC.
(3) Extraction of characteristics of endoscopic treatment-related factors for postoperative bleeding after EST in patients taking DOAC.
(4) Differences between DOAC types for postoperative bleeding after EST in patients taking DOAC.
(5) Correlation of CHADs score on postoperative bleeding after EST in patients taking DOAC.
