Abstract
Background/Aims
Few studies have classified risk factors according to the onset time of bleeding after endoscopic submucosal dissection (post-ESD bleeding).
Methods
We studied 1767 consecutive lesions in patients who underwent ESD for early gastric cancer from December 2006 through June 2016. Patients who had a remnant stomach or who had undergone reconstruction with a gastric tube were excluded. Post-ESD bleeding was classified into acute bleeding (0–5 days after ESD) and delayed bleeding (6 or more days after ESD), and the risk factors for each type of bleeding were compared.
Results
Post-ESD bleeding occurred in 150 (8.5%) of 1767 lesions. Bleeding was acute in 129 lesions (7.3%) and delayed in 21 (1.2%). Acute post-ESD bleeding was frequently associated with lesions located in the distal stomach, expanded indications or non-indicated lesions, a specimen diameter of ≥40 mm, and antithrombotic therapy. Delayed post-ESD bleeding was often associated with lesions located in the proximal stomach, hemodialysis, and antithrombotic therapy. Among 334 lesions in patients who received antithrombotic therapy, post-ESD bleeding occurred in 47 lesions (14.1%). Independent risk factors for post-ESD bleeding were a specimen diameter of ≥40 mm and treatment with 2 or more antithrombotic agents.
Conclusions
Acute post-ESD bleeding and delayed post-ESD bleeding were associated with different clinical characteristics. Antithrombotic therapy is a risk factor for post-ESD bleeding in both the acute and delayed phases.
