EUS with EUS-guided fine-needle aspiration as the first endoscopic test for the evaluation of obstructive jaundice.
Gastrointestinal Endoscopy 2001 April
BACKGROUND: This study assesses the cost savings associated with using endoscopic ultrasound (EUS) before endoscopic retrograde cholangiopancreatography (ERCP) for evaluating patients with suspected obstructive jaundice.
METHODS: One hundred forty-seven patients with obstructive jaundice of unknown or possibly neoplastic origin had EUS as their first endoscopic procedure. With knowledge of the final diagnosis and actual management for each patient, their probable evaluation and outcomes and their additional costs were reassessed assuming that ERCP would have been performed as the first endoscopic procedure. Also calculated were the additional costs incurred if EUS were unavailable for use after ERCP and had to be replaced by computed tomography or other procedures.
RESULTS: The final diagnoses in these patients included malignancies (65%), choledocholithiasis or cholecystitis (18%), "medical jaundice" (11%), and miscellaneous benign conditions (6%). Fifty-four percent had EUS-guided fine-needle aspiration but only 53% required ERCP after EUS. An EUS-first approach saved an estimated $1007 to $1313/patient, but the cost was $2200 more if EUS was unavailable for use after ERCP. Significant savings persisted through sensitivity analysis.
CONCLUSIONS: Performing EUS with EUS-guided fine-needle aspiration as the first endoscopic procedure in patients suspected to have obstructive jaundice can obviate the need for about 50% of ERCPs, helps direct subsequent therapeutic ERCP, and can substantially reduce costs in these patients.
