Echotip® ProCore™ High Definition Ultrasound Biopsy Needle Provides Greater Accuracy in Diagnosing GI Cancers

EUS is an established procedure for diagnosing GI cancers and determining the stage of their development. Most often, a very fine needle is used—but fine-needle aspiration (FNA) can have limited yield and sensitivity for certain kinds of tumors or in some anatomical locations and only procures a cytological sample.

The EchoTip ProCore needles circumvent this limitation by obtaining intact tissue samples, allowing for a histological diagnosis rather than conventional cytological diagnosis based on individual cells. In addition to this advantage, the needles are designed to access difficult-to-reach tissue in areas of the GI tract such as the pancreatic head.

In the five-center study to be published in Gastrointestinal Endoscopy, the 19-gauge EchoTip ProCore retrieved adequate histological tissue samples in 89.5 percent of cases, and subsequent diagnosis proved accurate in more than 85 percent of total cases. The overall accuracy for detecting malignancy in EchoTip ProCore samples was greater than 92 percent. Moreover, 78 percent of the samples were collected with just one pass of the needle; in FNA, the recommended number of passes can be as high as seven. Researchers studied 109 patients with 114 intestinal lesions and/or peri-intestinal lymph nodes.

Used with an ultrasound endoscope for fine needle biopsy (FNB) of submucosal lesions, mediastinal masses, lymph nodes and intraperitoneal masses within or adjacent to the gastrointestinal tract.
