Background: Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasonography-guided tissue acquisition (EUS-TA) are increasingly performed in the same session in patients with malignant biliary obstruction. In this retrospective analysis, we investigated adverse events (AE) after same session ERCP and EUS-TA. Methods: Patients with malignant distal biliary obstruction who underwent EUS-TA and/or ERCP with self-expandable metal stent (SEMS) placement from January 2015 to April 2020 were included. Primary outcome was post-procedural pancreatitis (PPP). Secondary outcomes were other procedure-related AE. Results: We included 494 patients, of which 118 patients (24%) underwent same session EUS-TA+ERCP, 51 patients (10%) underwent separate session EUS-TA & ERCP, 90 patients (18%) ERCP-only and 235 patients (48%) EUS-TA only. PPP occurred in 22 patients (19%) after same session EUS-TA+ERCP and in 6 patients (12%) after separate EUS-TA & ERCP (p = 0.270).

Primary outcome was post-procedural pancreatitis (PPP). Secondary outcomes were other procedure-related AE.

PPP occurred in 22 patients (19%) after same session EUS-TA+ERCP and in 6 patients (12%) after separate EUS-TA & ERCP (p = 0.270). When adjusted for other known risk factors (i.e., difficult procedure), the difference in PPP remained non-significant (adjusted odds ratio 1.74 (95%-CI 0.65-4.67, p = 0.268). The incidence of other AE was similar, although the overall AE rate was significantly higher after same session EUS-TA+ERCP (36% vs. 20%, p = 0.030). Conclusion: Same session EUS-TA+ERCP did not significantly increase the incidence of PPP, although overall AE were significantly higher. These data warrant further prospective studies.Show less
