BACKGROUND AND AIM: Although the role of @entity3821 ( @entity3821 ) in the evaluation of specific disease entities is well known, its utility in evaluating indeterminate findings in a heterogeneous group of @entity1 undergoing endoscopic retrograde cholangiopancreatography (ERCP) is unknown. This study evaluates the diagnostic accuracy of @entity3821 in @entity1 with indeterminate findings at ERCP. METHODS: This was a prospective study of all @entity1 who underwent @entity3821 for evaluation of an indeterminate @entity253 or main @entity788 noted at ERCP over an 8-month period. The accuracy of @entity3821 was established based on long-term follow-up, surgery, or further investigations. RESULTS: Twenty-nine (5%) of 600 @entity1 who underwent ERCP had an indeterminate finding that warranted further evaluation by @entity3821 : this was @entity253 in 19 @entity1 and @entity384 in 10. Technical success was 100%. Mean duration of follow-up was 435 days (range 192-614 days). In @entity1 with @entity253 , @entity3821 diagnosed 11 as benign and eight as malignant. In @entity1 with @entity384 , @entity3821 diagnosed @entity5 in six @entity1 and chronic @entity788 in four. Findings on @entity3821 supported the correct diagnosis in 27 of 29 @entity1 (93%). In two @entity1 with dominant hilar stricture in the setting of @entity991 , @entity3821 was false positive in one and false negative in the other. One @entity1 died of @entity177 due to post-ERCP @entity788 . CONCLUSIONS: A technically easy procedure, @entity3821 offers unique advantages in the evaluation of @entity1 with indeterminate findings at ERCP.
