Effect of Defect Closure on Delayed Bleeding in Gastric Endoscopic Submucosal Dissection: A Single Center Experience.
Article in Digestive diseases and sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
BACKGROUND AND
aimsEndoscopic submucosal dissection (ESD) is an effective treatment for gastric neoplasia, but delayed bleeding remains a potential complication. This study evaluated the impact of defect closure techniques on delayed bleeding following gastric ESD.
methodsA retrospective analysis was conducted on 135 patients (51% male; mean age 67 ± 15 years) who underwent gastric ESD. Lesion characteristics, resection outcomes, closure methods, and adverse events were analyzed. The association between defect closure and delayed bleeding was assessed using Fischer exact test, univariate regression, and multivariable regression.
resultsThe mean lesion diameter was 48 ± 26 mm, with lesions primarily located in the stomach body (51%) and antrum/prepyloric region (38%). En-bloc resection was achieved in 97% of cases, with R0 resection in 91.1% and curative resection in 87.4%. Defect closure was performed in 33.3% of cases. Delayed bleeding occurred in 6.7% of patients (n = 9), including 6 in the non-closure group and 3 in the closure group. No cases of deep muscle injury or delayed perforation were observed. There was no significant difference in delayed bleeding between closure and non-closure groups (6.7% vs. 6.5%, P = 1.000). Multivariable analysis further confirmed no significant association between defect closure and delayed bleeding (OR 0.777, 95% CI 0.152-3.965, P = 0.762).
conclusionsDefect closure did not significantly reduce delayed bleeding rates in gastric ESD. Routine closure may not be necessary while selective application in high-risk patients warrants further investigation.
