Diagnostic value of peroral choledochoscopy combined with modified biopsy forceps for malignant biliary strictures: a two-center retrospective study
Clinical Report: Evaluating the Diagnostic Utility of Peroral Choledochoscopy
Overview
This study evaluates the diagnostic value and safety of peroral cholangioscopy (POCS) combined with modified biopsy forceps for malignant biliary strictures (MBS).
Background
Biliary strictures can lead to obstructed bile flow and cholestasis, often resulting in significant clinical consequences. Differentiating between benign and malignant biliary strictures is crucial, as misdiagnosis can lead to unnecessary surgical interventions. Current diagnostic methods, including ERCP, face challenges in obtaining sufficient tissue samples, highlighting the need for improved techniques.

Key Findings
POCS allows for direct visualization of the bile duct, improving biopsy precision.
Modified biopsy forceps enhance the diagnostic accuracy for MBS.
Misdiagnosis of biliary strictures can lead to unnecessary surgical interventions.
Approximately 15% to 24% of patients with suspected MBS are confirmed to have benign strictures post-surgery.
Cholangiocarcinoma is the most common cause of malignant biliary strictures.
Clinical Implications
This study evaluates the diagnostic capabilities for MBS.
Conclusion
This study evaluates the use of POCS with modified biopsy forceps for the diagnosis of malignant biliary strictures.
