Abstract:Percutaneous biopsy provides an effective means of tissue diagnosis in pancreatic lesions. Accuracy rates are ranging between 72 and 100%, with a sensitivity for carcinomas between 69 and 90% and a constantly high specificity of 100% in most series of the literature. The rate of major complications is low, with an incidence of about 0.05%.
“…Pancreatic biopsies have been reported to be slightly less accurate than other abdominal biopsies (8, 15, 36). This is said to be the result from the usual coexistence of inflammation with malignancy and the difficulties of diagnosing pancreatic carcinomas based on cytologic samples alone.…”
This review will discuss the benefits and disadvantages of ultrasound-guided percutaneous fine-needle aspiration and cutting needle biopsies. Clinical efficacy, cost-effectiveness, some controversies and safety will be reviewed.

“…Zur sicheren Klärung der Dignität von Veränderungen und zur Therapieplanung ist jedoch zumeist die histopathologische Diagnose ausschlaggebend. Zur Gewinnung von Gewebematerial gilt die CT-gesteuerte Punktion als etabliertes Verfahren mit geringen Komplikationsraten und kommt auch bei Kindern bereits zum Einsatz [1,2]. Verbesserungen der Biopsienadeln [3] und neuere Biopsietechniken wie die CT-Fluoroskopie haben in den letzten Jahren zu einer kontinuierlichen Verbesserung und Akzeptanz der CTunterstützten Biopsien geführt und die Sicherheit und Effizienz des Verfahrens verbessert.…”
The navigation system allows for safe interventions in case of angulated needle access with high accuracy and little tissue trauma. However, insufficient corrections for respiration movement constitute a substantial limitation of the tool.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
