Single-session endosonography and endoscopic retrograde cholangiopancreatography for biliopancreatic diseases is feasible, effective and cost beneficial.

Background: Endoscopic ultrasonography (EUS) and Endoscopic Retrograde Cholangiopancreatography (ERCP) are often required in patients with pancreaticobiliary disorders.

Aims: To assess the clinical impact and costs savings of a single session EUS-ERCP.

Methods: Patient and intervention data from April 2009 to March 2012 were prospectively recruited and retrospectively analyzed from a database at a tertiary hospital. Indications, diagnostic yield, procedure details, complications and costs were evaluated.

Results: Fifty-five scheduled combined procedures were done in 53 patients. The accuracy of EUS-fine needle aspiration for malignancy was 90%. The main clinical indication was a malignant obstructing lesion (66%). The ERCP cannulation was successful in 67%, and in 11/15 failed ERCP (73%), drainage was completed thanks to an EUS-guided biliary drainage: 6 transmurals, 5 rendezvous. Eight patients (14%) had related complications: bacteremia (n = 3), pancreatitis (n = 2), bleeding (n = 2) and perforation (n = 1). The mean duration was 65 ± 22.2 min. The mean estimated cost for a single session was €3437, and €4095 for two separate sessions. The estimated cost savings using a single-session strategy was €658 per patient, representing a total savings of €36,189.

Conclusion: Combined EUS and ERCP is safe, technically feasible and cost beneficial. Furthermore, in failed ERCP cases, the endoscopic biliary drainage can be completed with EUS-guided biliary access in the same procedure.
