Diagnostic Differentiation Between Two Rare Entities-Metastatic Peritoneal Mesothelioma With Duodenal Involvement and Duodenal Synovial Sarcoma: A Case Report.

This case report highlights the diagnostic challenges in distinguishing between metastatic peritoneal mesothelioma with duodenal involvement and synovial sarcoma of the duodenum, two rare and complex entities. A 59-year-old woman presented with nonspecific abdominal symptoms, and imaging revealed a heterogeneous lesion between the right hepatic lobe and duodenum. Endoscopic ultrasound-guided biopsy and subsequent histopathological analysis initially suggested synovial sarcoma, but further examination, including a FISH assay, confirmed the diagnosis of malignant peritoneal mesothelioma.

Correlation between liver volume drainage and clinical success after endoscopic biliary drainage of hilar malignant obstruction.

Background And Aim: Malignant hilar obstruction usually presents in advanced-stage disease with a poor prognosis. Effective biliary drainage is essential for the beginning of palliative chemotherapy. There is a debate on the amount of liver parenchyma that should be drained to achieve clinical success.

12-mm Versus 10-mm Metallic Stents for Malignant Biliary Obstructions: A Systematic Review and Meta-Analysis.

Background And Aims: Endoscopic drainage of malignant biliary obstruction using metal stents is widely used to treat obstructive jaundice. However, the occurrence of stent occlusion or migration raises the hypothesis using stents with larger diameters may be associated with better outcomes.

Methods: PubMed, Embase, and Cochrane databases were systematically searched for studies comparing 10-mm vs.
