Dental-floss traction-assisted endoscopic full-thickness resection of a gastrointestinal exophytic tumor: A case report.
Article in SAGE open medical case reports, 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
Exophytic gastrointestinal tumors, including gastrointestinal stromal tumors and leiomyomas, present unique technical challenges due to their predominantly outward growth pattern. Conventional endoscopic techniques, such as endoscopic mucosal resection and endoscopic submucosal dissection, often have limitations in achieving complete resection in these cases, and surgical approaches are therefore frequently required. We report a case of an exophytic gastric tumor successfully treated using dental floss-assisted traction combined with endoscopic full-thickness resection. This approach improved lesion exposure by enabling active repositioning of the extraluminal component into the gastric lumen, thereby enhancing procedural controllability. This case highlights a practical technical strategy for managing selected exophytic lesions and suggests that endoscopic resection may represent a feasible minimally invasive alternative in appropriately selected patients.
