Operative, safety and economic outcomes of endoscopic submucosal dissection in older adults: a retrospective real-world analysis.
Article in BMC gastroenterology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 a cornerstone organ-preserving treatment for colorectal neoplasia; however, the impact of advanced age on procedural efficiency, safety, and economic burden remains controversial. This study aimed to comprehensively evaluate these outcomes in older adults within a real-world clinical setting.
methodsWe retrospectively reviewed 255 patients who underwent colorectal ESD between January 2022 and December 2023. Patients were divided into elderly (≥ 65 years, n = 119) and non-elderly (< 65 years, n = 136) groups. Operative outcomes (resection and wound-management speeds), safety (delayed bleeding and perforation), and economic metrics (hospital stay and costs) were evaluated. Multivariable regression, age-stratified models, and 1:1 propensity score matching (PSM) were utilized to rigorously adjust for baseline confounders.
resultsElderly patients presented with significantly larger and morphologically more complex lesions. Nevertheless, multivariable analyses demonstrated no significant independent association between age and resection speed or wound-management speed, which was fully supported by subsequent PSM and restricted cubic spline (RCS) analyses. Complication rates were extremely low (2.0% for bleeding, 0.8% for perforation) with no descriptive differences between groups. Although initial regression models suggested a slight age-related increase in hospital costs and length of stay, these economic disparities were attenuated and lost significance after applying PSM to balance clinical drivers such as ASA physical status and anesthesia methods (matched hospital costs: 11.39k vs. 10.57k RMB, p = 0.249; identical median stay: 4 vs. 4 days).
conclusionsAppropriately selected elderly patients achieve operative and safety outcomes comparable to younger individuals during colorectal ESD. The initial economic variances observed are likely driven by underlying comorbidities and anesthetic requirements rather than chronological age itself. Clinical decisions should prioritize comprehensive, patient-centered assessments over strict age cutoffs.
