Endoscopic Retrograde Cholangiopancreatography in Acute Biliary Pancreatitis: Urgent vs. Delayed and the Outcome of Same-Admission Cholecystectomy.

Acute pancreatitis (AP) represents a major burden for the medical system, associating important morbidity and mortality rates. This paper is focused on debatable aspects of the management of biliary AP, namely indications, timing and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) on the hand and, on the other hand, same-admission cholecystectomy as a preventive measure for recurrent disease. Material and methods: This is a retrospective study including 108 patients with biliary AP in whom ERCP was performed, treated in the Clinical Emergency Hospital of Bucharest between 2016 and 2020. According to the urgency of the ERCP, we divided the patients into two groups: urgent versus delayed ERCP. Urgent ERCP was performed in 52 patients, while delayed ERCP was performed in 56 patients; the hospital stay was higher in the urgent group than in the delayed group (10 days vs 8 days, p = 0.299) with no difference in morbidity rates. The mean time between ERCP and surgery was 5 days, without significant difference between the groups. The laparoscopic approach was the preferred method, with a conversion rate of 7%. Conclusion: ERCP with stone extraction followed by same-admission laparoscopic cholecystectomy is a safe therapeutic option, that prevents recurrent pancreatitis. The timing of the procedures remains debatable, further prospective studies being needed to achieve statistical significance.
