Abstract

Abstract : Background and Aim: Esophageal endoscopic submucosal dissection (ESD) to resect widespread lesions has increased the incidence of strictures, and some patients develop strictures despite receiving prophylactic locoregional triamcinolone injections. The present study evaluated the predictive factors for esophageal stricture formation in patients given prophylactic triamcinolone injections after ESD. Methods: This was a retrospective observational study. Of 552 consecutive patients who underwent ESD, those who received prophylactic triamcinolone injections immediately after ESD were enrolled. Primary outcome was predictive factors for esophageal stricture formation in patients given prophylactic triamcinolone injections. Results: We evaluated 101 en bloc resections involving 144 lesions in 96 patients. Strictures occurred following 17 (16.8%) resections. Wider circumferential mucosal defect (odds ratio [OR] 2.42, 95% confidence interval [CI]: 1.01–5.80; P = 0.048) was an independent predictive factor for stricture development. Cut‐off value associated with stricture formation was five‐sixths of the circumferential mucosal defect. Propensity analysis determined that frequency of esophageal strictures increased in patients with circumferential mucosal defects of more than five‐sixths compared with those less than five‐sixths (OR = 5.70, 95% CI: 1.61–20.18; P = 0.007). Conclusion: Resections involving circumferential mucosal defects of more than five‐sixths increased the likelihood of stricture formation in patients given prophylactic locoregional triamcinolone injections after esophageal ESD.
