Prophylactic effect of compression stockings for elevated D-dimer levels following endoscopic submucosal dissection.

Objectives: A relationship between endoscopic submucosal dissection (ESD) and deep vein thrombosis has been recognized. We previously reported that a high corrected midazolam dose (total midazolam dose/initial dose of midazolam used to induce sedation) is related to elevated D-dimer levels after ESD. In this study, the effect of compression stockings (CSs) in preventing thrombosis following ESD under sedation was evaluated by measuring D-dimer levels before and after ESD. Methods: The participants were patients who underwent ESD for upper gastrointestinal tumors during the period between April 2018 and October 2022. Patients with pre-ESD D-dimer levels ≥1.6 µg/m and patients with corrected midazolam doses ≤3.0 were excluded. A retrospective investigation of the relationship between CS use and high post-ESD D-dimer levels (difference in D-dimer levels ≥1.0 µg/mL between before and after ESD) was conducted. Results: There were 27 patients in the non-CS group (NCS) and 33 patients in the CS group. The number of patients with high post-ESD D-dimer levels was 13 (48.2%) in the non-CS group and six (18.2%) in the CS group; the number in the CS group was significantly lower ( Conclusion: Wearing CSs was related to a lower risk of high post-ESD D-dimer levels. This result suggests that thrombus formation is a cause of elevated D-dimer levels after ESD.
