Clinical study of extrahepatic biliary adenoma.
Article in World journal of clinical cases, 2023. 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
backgroundBiliary adenomas that occur in the extrahepatic biliary tree are rare. It is difficult to distinguish it from cholangiocarcinoma or cholangiolithiasis by various imaging examinations, and it is very easy to be misdiagnosed.
aimTo evaluate the cumulative experiences including clinical characteristics and treatments of nine patients diagnosed with extrahepatic biliary adenoma admitted to the First Affiliated Hospital of Xi'an Jiaotong University from 2016 to 2022.
methodsA total of nine patients were included in our study. The laboratory examinations, disease diagnosis, therapy and pathological characteristics, and follow-up of every patient were evaluated.
resultsOur cohort consisted of six females and three males with an average diagnosis age of 65.1 years (range 46-87). Six extrahepatic biliary adenomas were located in the common bile ducts and three in the hepatic duct. On initial presentation, all of the patients have symptom of biliary origin, including obstructive jaundice (4/9, 44.4%), abdominal pain (6/9, 66.7%), and fever (3/9, 33.3%). Preoperative imaging examination considered bile duct carcinoma in 6 cases and bile duct calculi in 3 cases. All the patients received surgical treatment and were confirmed by pathology as biliary adenoma. The symptoms improved significantly in all 9 patients after surgery. Seven of nine patients recovered well at follow-up without tumor recurrence. One patient died 2 mo after the surgery due to heart failure. One patient developed jaundice again 8 mo after surgery, underwent endoscopic retrograde cholangiopancreatography and biliary stent placement.
conclusionBenign extrahepatic biliary tumors are rare and difficult to diagnosis preoperatively. Intraoperative choledochoscopy and timely biopsy may offer great advantages.
