When the Gleam of Obstruction Isn't Just Stones: A Case Report of Intraductal Papillary Neoplasm of the Bile Duct (IPNB) and the Role of Cholangioscopy in Its Management.
Article in Cureus, 2024. 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
Intraductal papillary neoplasm of the bile duct (IPNB) is a precursor lesion to biliary tract carcinoma. It is characterised by papillary growth within the bile ducts. The diagnosis and management of IPNB are challenging due to its varying presentations and overlapping features with other biliary diseases. We present a case of a 58-year-old male with a history of vomiting, nausea, and upper abdominal discomfort. He also had a history of Gilbert syndrome and hairy cell leukaemia. Imaging studies showed filling defects in the common bile duct (CBD) and a moderate intrahepatic biliary duct prominence. An endoscopic retrograde cholangiopancreatography (ERCP) revealed a soft tissue lesion in the mid-CBD along with significant biliary dilation. Using SpyGlass cholangioscopy, a large polypoid tumour extending from the ampulla was directly visualised, and biopsies confirmed low-grade dysplasia without invasive characteristics. This report highlights the importance of recognising the clinical and radiological features of IPNB and emphasises the role of cholangioscopy in the management of this rare disorder.
