摘要

Background and Aims

Prophylactic colonic endoscopic submucosal dissection (ESD) defect closure may reduce delayed adverse events (DAEs) such as bleeding and perforation associated with ESD and facilitate same day discharge. We compared the effect of colonic ESD defect closure (closed group) with no closure (open group) on DAEs and overnight hospital admission.

Methods

We performed a Western multicenter retrospective study on patients who underwent colon ESD. Rectal lesions were excluded. DAEs were defined as adverse events within 2 weeks of ESD. Primary outcome measures were DAEs and overnight hospital admission. Multivariate analyses were performed.

Results

560 patients underwent colon ESD and 364 (71.8%) patients had complete defect closure. Closed group had a significantly lower rate of delayed bleeding (1.7% vs 5.6%, p = 0.03) compared to open group. Multivariate analysis with adjusted odds ratios (aOR) revealed right sided polyps (aOR = 7.0) and anticoagulation/antiplatelet agents (aOR = 6.6) increased the risk while defect closure (aOR = 0.2) decreased the risk of delayed bleeding. Defect closure amplified the reduction in risk of delayed bleeding (2.4% vs 10.4%, p = 0.014) for right-sided polyps. Malignant polyps significantly increased the risk of delayed perforation (aOR = 3.3) and overnight hospitalization (aOR = 2.9). Defect closure (aOR = 0.6), traction use (aOR = 0.6) and topical hemostatic agent use (aOR = 0.4) significantly reduced the risk of overnight hospitalization.

Conclusion

Prophylactic closure of colon ESD defects was associated with a significant reduction in delayed bleeding with number needed to treat (NNT) of 25.6 (especially for right sided polyps, NNT 12.5), and post-procedural overnight hospitalization. Prospective studies are needed to further validate these results.
