SAN DIEGO, Calif.—Cook Medical has added a 25-gage needle to its EchoTip® ProCore™ line of fine-needle biopsy (FNB) histology needles, which are designed for use in endoscopic ultrasound, or EUS. The EchoTip ProCore is a single-use, disposable needle for FNB intended for sampling of submucosal lesions, mediastinal masses, lymph nodes and intraperitoneal masses.
The new 25-gage biopsy needle enabled a single-pass diagnosis of 88 percent (91 percent when including subsequent passes) in suspected tumors of the pancreas when pathologists examined both the histological and cytological yields obtained. No complications were seen in any of the patients.
The American Cancer Society estimates that 43,920 people in the United States will be diagnosed with pancreatic cancer in 2012. Because of its location deep inside the body and lack of symptoms, pancreatic cancer can be difficult to detect and diagnose in the early stages. Endoscopic ultrasound is an established procedure for diagnosing GI cancers and determining the stage of their development.
Most often, a very fine needle is used to gain samples from hard-to-reach areas such as the pancreas, but fine-needle aspiration (FNA) can have limited yield and sensitivity for certain kinds of tumors or in some anatomical locations. Using the 25-gage EchoTip ProCore needle may lead to an increase in diagnosis for pancreatic malignancies on the first pass because of its small size and a modified slow-pull technique for tissue acquisition.
