Challenges in diagnosing and treating distal common bile duct adenocarcinoma: A case report with literature insights.
Article in International journal of emergency medicine, 2025. 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
backgroundAdenocarcinoma of the distal common bile duct (CBD) is a rare and aggressive malignancy that is often diagnosed at an advanced stage owing to nonspecific symptoms and delayed presentation. This case report details the diagnostic and therapeutic challenges associated with distal CBD adenocarcinoma and highlights the need for an effective multidisciplinary approach. CASE PRESENTATION: A 54-year-old male with a significant smoking history presented with persistent right upper abdominal pain, dark urine, and scleral jaundice. Imaging studies revealed intrahepatic bile duct dilatation, a mass obstructing the common bile duct, and thickened gallbladder walls. Despite initial antibiotic therapy for suspected cholangitis, the patient underwent endoscopic retrograde cholangiopancreatography (ERCP) and subsequently a surgical procedure. The surgical resection of a common bile duct adenocarcinoma with lymphovascular invasion was successful, with subsequent restoration of bile flow through Roux-en-Y hepaticojejunostomy. Histopathological analysis confirmed tumor characteristics and clear surgical margins. Postoperatively, the patient demonstrated significant clinical improvement with normalized bilirubin levels and received appropriate management for his oncologic condition.
conclusionThis case highlights the diagnostic complexity of distal CBD adenocarcinoma, particularly in patients with delayed symptoms. Multimodal imaging approaches and timely surgical intervention are crucial for effective management of this malignancy. Enhanced awareness of atypical presentations and advancements in targeted therapies holds promise for improving outcomes in such challenging cases.
