Upper gastrointestinal endoscopic submucosal dissection using an ultrathin endoscope: a retrospective, single-center evaluation.
Article in Surgical endoscopy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundRecent studies have reported the therapeutic use of endoscopic submucosal dissection (ESD) using an ultrathin endoscope for targeting pharyngeal and distal side lesions in the stenosis or as a less invasive treatment via the nasal route. However, the effectiveness and safety of these treatments remain undetermined. Therefore, this study aimed to review treatment outcomes and discuss the advantages and precautions of the treatments based on our experience.
methodsThis study included 13 patients with 14 lesions who underwent 14 sessions of upper gastrointestinal ESD using an ultrathin endoscope between December 2021 and August 2023. The outcome measures included lesion background, en bloc resection rate, en bloc complete resection rates, and incidence of adverse events (including post-operative bleeding, intraoperative perforation, and delayed perforation).
resultsThe lesions in the esophagus, stomach, and duodenum were eight, three, and three, respectively, and the median length (range) of each located lesion was 16.5 (6-26), 17 (9-36), and 10 (4-16) mm, respectively. En bloc resection and en bloc complete resection rates were 100 and 92.9%, respectively. The only adverse event was an intraoperative perforation observed during duodenal ESD, resulting from the assistant's inadvertent expansion of the SOUTEN at the final dissection stage.
conclusionOur results demonstrate that ESD with an ultrathin endoscope effectively reaches lesions in difficult locations and enables treatment within a small working space. Therefore, ESD using an ultrathin endoscope is a treatment option for lesions located distally to gastrointestinal stenosis, highly fibrotic lesions, and duodenal tumors.
