Diagnostic performance of endoscopic ultrasound through‐the‐needle microforceps biopsy of pancreatic cystic lesions: Systematic review with meta‐analysis

Objectives Endoscopic ultrasound through‐the‐needle biopsy (EUS‐TTNB) is a useful tool for differential diagnosis among pancreatic cystic lesions (PCLs). Cystic fluid cytology (CFC) is recommended by guidelines, but its diagnostic accuracy is about 50%. The aim of this meta‐analysis is to assess the clinical impact of EUS‐TTNB in terms of technical success (TS), histological accuracy (HA) and diagnostic yield (DY). Methods Original studies in...
