A multicenter retrospective study on the risk factors of stricture formation after moderate circumferential defect resection in esophageal endoscopic submucosal dissection.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEndoscopic submucosal dissection (ESD) is an effective treatment for superficial esophageal cancer, but postoperative stenosis remains a considerable concern. Particularly, the probability of stenosis is less investigated in patients with a 50-75% circumferential mucosal defect. We identified the risk factors of postoperative stenosis after moderate circumferential defect resection in esophageal ESD.
methodsThis multicenter retrospective observational study analyzed data from 513 patients with 50-75% circumferential mucosal defect after esophageal ESD across 19 institutions from April 2018 to March 2022. The risk factors for postoperative esophageal stenosis, including steroid use, were investigated.
resultsPostoperative stenosis was observed in 28 cases (5%). Multivariate analyses identified prior endoscopic treatment close to the lesion (odds ratio [OR], 5.10), cervical esophageal lesion (OR, 3.97), large circumferential defect (OR, 3.78), and longer procedural duration (OR, 3.83) as the independent risk factors for stenosis formation. In the sensitivity analysis using ridge-penalized logistic regression, only circumferential defect > 5/8 (OR, 3.30; 95% CI 1.56-7.66) and procedure time > 120 min (OR, 3.61; 95% CI 1.39-8.25) remained robust predictors; cervical location and prior endoscopic treatment were shrunk toward the null. Particularly, patients with a prior endoscopic treatment, a cervical esophageal lesion, and more than 5/8 of circumferential defect were likely to have stenosis postoperatively despite steroid use.
conclusionIn patients with a 50-75% circumferential mucosal defect after esophageal ESD, steroids were used in > 40% of the patients, with 5% of the patients developing postoperative stenosis. Larger circumferential mucosal defect and longer procedural duration were considered as the most relevant risk factors. Stricture prevention should be more aggressively considered in cases at high-risk for stenosis, even though the mucosal defect area was less than three-fourth of the circumference.
