Value of contrast‐enhanced harmonic endoscopic ultrasonography with enhancement pattern for diagnosis of pancreatic cancer: A meta‐analysis

Current imaging modalities are limited in their ability to distinguish pancreatic cancer (PC) from non‐neoplastic pancreatic lesions. The diagnostic use of contrast‐enhanced endoscopic ultrasonography (CE‐EUS) has increased, and its utility has been reported. Recently, contrast‐enhanced harmonic EUS (CH‐EUS) was reported to facilitate imaging of parenchymal perfusion and microvessels in pancreatobiliary diseases, leading to a high diagnostic accuracy for PC. The present meta‐analysis aims to investigate the usefulness of CH‐EUS with enhancement pattern for PC diagnosis.
