Background:
Acute biliary pancreatitis (ABP) is often associated with persistent common bile duct (CBD) stones. The best strategy in terms of timing of surgery is still controversial. The aim of the current study is to describe the prevalence of persistent common bile duct (CBD) stones in ABP during the first week of symptoms at a high-volume referral center.
Study Design:
Single-institution retrospective analysis of a prospectively collected database. Patients with diagnosis of ABP who underwent laparoscopic cholecystectomy (LC) between January 2009 and December 2019 were extracted.
Results:
Two hundred thirty-one patients were included. Cholecystectomy was performed laparoscopically in 230 (99.57%) patients. Intraoperative cholangiogram was performed in all patients. Two hundred nine (90%) patients had surgery within the first 7 days. Global prevalence of persistent CBD stones during IOC was 19.91% (95% CI 14.96-25.65). No significant association between timing to surgery and presence of CBD stones was found for the first week since the initial attack (p=0.28). Prevalence of CBD stones was significantly higher after day 7 (p=0.007 and 0.005). Positive findings in preoperative MRCP are significantly related to intraoperative CBD stones (p=0.0001). Mild postoperative complications (CD I/II) were present in 21 patients (9.09%). No difference was found in morbidity between CBD stones group and non-CBD stones group (p=0.48). We observed no severe complications nor mortality.
Conclusions:
In patients with mild acute biliary pancreatitis, the prevalence of persistent CBD stones does not change within the first 7 days since the onset of symptoms. This fact may have major clinical relevance when deciding the optimal therapeutic strategy in this population.

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
