Core Tip

Core tip: Management of pancreatic solid mass lesions relies greatly on accuracy of diagnosis of these lesions. Procore fine needle biopsy needles have been found to have a diagnostic accuracy comparable to, if not better than the standard needles in diagnosing the intestinal and extra-intestinal mass lesions. Amongst the Procore needles, the 19G and 22G Procore needles have both been shown to obtain good quality core tissue samples but both have unique characteristics of their own. This meta-analysis compares the feasibility and accuracy of 19G and 22G Procore needles in determining the diagnosis of solid mass lesions.
