Background:
Choledocholithiasis causing acute biliary pancreatitis (ABP) may migrate to the duodenum or persist in the common bile duct (CBD). We developed a model for predicting persistent choledocholithiasis (PC) in patients with ABP.
Methods:
This retrospective cohort study included 204 patients, age ≥18 years (mean age: 73 years, 65.7% women), admitted for ABP in 2013-2018, with at least a magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasonography (EUS), and/or endoscopic retrograde cholangiopancreatography (ERCP). Epidemiological, analytical, imaging, and endoscopic variables were compared between patients with and without PC. Multivariate logistic regression analyses were performed to develop a predictive model of PC.
Results:
Patients underwent MRCP (n=145, 71.1), MRCP and ERCP (n=44, 21.56%), EUS and ERCP (n=1, 0.49%), or ERCP (n=14, 6.86%). PC was detected in 49 patients (24%). PC was strongly associated with CBD dilation, detected in the emergency ultrasound (p<0.001; OR=27; 95% CI: 5.8-185.5), increased blood levels of gamma glutamyl transpeptidase, detected at 72h (p=0.008; OR=3.4; 95% CI: 1.5-8.9); and biliary sludge in the gallbladder (p=0.008; OR=0.03; 95% CI: 0.001-0.3).
Conclusions:
The predictive model showed a validated area under the curve (AUC) of 0.858 for detecting PC in patients with ABP. A nomogram was developed based on model results.
Conclusions:
The predictive model was highly effective in detecting PC in patients with ABP. Therefore, this model could be useful in clinical practice.

Acute Pancreatitis II: Clinical Manifestations and Management
Chronic Pancreatitis I: Introduction
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.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Acute 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:
