Background
Endoscopic retrograde cholangiopancreatography (ERCP) within 72 h is suggested for patients presenting with acute biliary pancreatitis (ABP) and biliary obstruction without cholangitis. This study aimed to identify if urgent ERCP (within 24 h) improved outcomes compared to early ERCP (24–72 h) in patients admitted with predicted mild ABP.
Methods
Patients admitted for predicted mild ABP defined as a bedside index of severity in acute pancreatitis score < 3 and underwent ERCP for biliary obstruction within 72 h of presentation during the study period were included. Patients with prior biliary sphincterotomy or surgically altered anatomy preventing conventional ERCP were excluded. The primary outcome was the development of moderately severe or severe pancreatitis based on the revised Atlanta classification. Secondary outcomes were the length of hospital stay, the need for ICU admission, and ERCP-related adverse events (AEs).
Results
Of the identified 166 patients, baseline characteristics were similar between both the groups except for the WBC count (9.4 vs. 8.3/µL; p < 0.044) and serum bilirubin level (3.0 vs. 1.6 mg/dL; p < 0.0039). Biliary cannulation rate and technical success were both high in the overall cohort (98.8%). Urgent ERCP was not associated with increased development of moderately severe pancreatitis (10.4% vs. 15.7%; p = 0.3115). The urgent ERCP group had a significantly shorter length of hospital stay [median 3 (IQR 2–3) vs. 3 days (IQR 3–4), p < 0.01].
Conclusion
Urgent ERCP did not impact the rate of developing more severe pancreatitis in patients with predicted mild ABP but was associated with a shorter length of hospital stay and a lower rate of hospital readmission.
