Bouveret Syndrome Presenting as Duodenal Bulb Stenosis and Gastric Outlet Obstruction: A Case Report.
Article in Cureus, 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
Bouveret syndrome, or gallstone obstruction of the duodenum, is a rare cause of gastric outlet obstruction, where gallstones migrate through a bilioenteric fistula and obstruct the pylorus or duodenum. Here, we present a case of a 61-year-old man who presented with intractable nausea and vomiting. Initial imaging, such as computed tomography of the abdomen and pelvis, showed gastric distention without an obvious obstructing lesion, and a subsequent upper endoscopy revealed a cholecystoduodenal fistula filled with gallstones, posterior to a stenotic region in the duodenal bulb. The calculi were spontaneously evacuated, the patient's symptoms resolved, and the patient was referred for surgical management. This case highlights the diagnostic challenges of Bouveret syndrome, particularly in the setting of atypical imaging, and emphasizes the importance of timely endoscopic assessment in uncovering rare etiologies of gastric outlet obstruction.
