Feasibility and Outcomes of Endoscopic Submucosal Dissection for Colorectal Premalignant and Early-Stage Malignant Lesions at a Community Hospital Serving Rural Population.
Article in Gastro hep advances, 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
Background and Aims: Shortage of specialists and distance to facility are known barriers associated with reduced colorectal cancer screening in rural America. Although data are sparse, rural patients are at risk for undergoing colectomy for a nonmalignant polyp due to lack of local expertise with advanced endoscopic resection techniques. We aim to study the feasibility and clinical outcomes of an endoscopic submucosal dissection (ESD) at a rural US health system. Methods: ESD was introduced in a planned manner at our community hospital that predominantly serves a rural population. Procedure data and clinical outcomes were reviewed for consecutive patients who underwent attempted ESD for colorectal premalignant and early-stage malignant lesions from February 2021 to January 2024. Results: Of 92 attempted ESDs, standard ESD technique was successful in 82 lesions (90.2%), while hybrid ESD-endoscopic mucosal resection technique was required for 9 lesions (9.8%) and 1 ESD was aborted. Forty-four (47.8%) lesions were in the right colon. For those who underwent standard ESD without hybrid technique, resection rates were en bloc 81 (98.7%), R0 62 (75.6%), and curative 58 (70.7%). Adverse events occurred in 4 (4.8%). There were no delayed perforations. Final pathology showed tubular or tubulovillous adenoma in 51 (62.2%), sessile serrated lesion in 2 (2.4%), high-grade dysplasia in 14 (17.1%), and adenocarcinoma in 15 (18.3%), with adenocarcinomas being staged T1 with low-risk features in 9 (11%) and ≥T1 with high-risk features in 6 (7.3%). Surveillance colonoscopy or surgical pathology was available in 44 (53.7%). Recurrent or residual polyp was noted in 1 (1.2%). Conclusion: ESD can be introduced at a community hospital with a high level of safety and efficacy.
