Distal Bile Duct Metastasis From Rectal Cancer: The Diagnostic Contribution of Intraductal Ultrasonography.
Article in DEN open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
A 49-year-old male developed liver dysfunction during chemotherapy for rectal cancer located in the rectosigmoid region. Although magnetic resonance cholangiopancreatography initially indicated sclerosing cholangitis, endoscopic retrograde cholangiopancreatography and intraductal ultrasonography revealed multiple non-contiguous intraductal masses. Histopathological analysis confirmed distal bile duct metastasis from rectal cancer, characterized by papillary intraductal lesions. The distribution and morphology of the tumors suggested implantation via bile flow or hematogenous dissemination through the peribiliary capillary plexus. Extrahepatic bile duct metastasis from colorectal cancer is exceptionally rare and poses significant diagnostic challenges. This report presents a rare case of distal bile duct metastasis detected during chemotherapy for rectal cancer, where endoscopic imaging was instrumental in establishing the diagnosis.
