Evidence suggests that endoscopic ultrasound (EUS) has similar accuracy to endoscopic retrograde cholangiopancreatography (ERCP) for detecting choledocholithiasis, and was associated with a reduced risk for complications in patients with mild or moderate acute biliary pancreatitis and a reduction in ERCP exposure. Endobronchial ultrasound-guided transbronchial lung biopsy was as accurate for identifying lung cancer in patients with peripheral pulmonary lesions as CT-guided percutaneous needle biopsy, and was associated with a reduced risk for procedural complications. Results were inconsistent among the studies included evaluating EUS and CT in pancreatic cancer. One Australian economic analysis suggested that endobronchial ultrasound-guided lung biopsy was associated with similar costs compared with CT-guided needle biopsy, but was sensitive to complication costs.
