AI Article Synopsis
- * Researchers analyzed 247 CP patients and used advanced imaging techniques to examine the stones, calculating their quantity and distribution patterns.
- * Results showed that alcoholic CP patients tended to have more uniformly distributed stones compared to those with idiopathic CP, with specific factors influencing stone count and distribution uniformity.
Article Abstract
Objectives: The aim of this study was to establish a standard to describe the spatial distribution of pancreatic stones in chronic pancreatitis (CP).
Methods: Two hundred forty-seven CP patients with pancreatic stones from June to December 2012 were enrolled. Two-dimensional images from coronal projection of 3-dimensional computed tomography images of pancreatic stones were gained. The number (n) of all stones and the geometric standard deviation (σ) of distances between the centroid of all stones and the centroids of every stone that represented the spatial distribution nonuniformity were calculated by Stone Reconstruction and Identification Programming System.
Results: The mean value of n and σ were 13.6 and 22.5; n > 13.6 and σ > 22.5 were determined as "multistones" and "nonuniform," respectively. Compared with alcoholic CP, idiopathic CP was less prone to multistones (odds ratio [OR], 0.310) and more prone to nonuniform (OR, 3.247). Pancreatic pseudocyst (OR, 2.211) in CP course was a risk factor of multistones, whereas diabetes mellitus in first-/second-/third-degree relatives (OR, 0.382) was a protective factor. Age at diagnosis of pancreatic stones (OR, 1.022) was a risk factor of nonuniformity.
Conclusions: Compared with idiopathic CP, alcoholic CP patients were prone to more pancreatic stones that distribute more uniformly.

Diverticulitis is a complication of a mostly benign condition called diverticulosis. Diverticulitis is a common illness that medical staff see in emergency departments and hospital inpatient services. The thought process behind this study was looking at the treatment of other diseases like pancreatitis or other critical illnesses and the data supporting timing of feeds.

Background: Congenital biliary dilatation (CBD) is a congenital malformation of the main biliary tract usually associated with the pancreatobiliary maljunction (PBM), determining stone formation, cholangitis, pancreatitis, and cholangiocarcinoma. The role of endoscopic retrograde cholangiopancreatography (ERCP) in treatment and diagnosis has not been established yet. Therefore, the aim of our study is to define the actual role of ERCP in children with CBD.

Circulating histones have been identified as essential mediators that lead to hyperinflammation, platelet aggregation, coagulation cascade activation, endothelial cell injury, multiple organ dysfunction, and death in severe patients with sepsis, multiple trauma, COVID-19, acute liver failure, and pancreatitis. Clinical evidence suggests that plasma levels of circulating histones are positively associated with disease severity and survival in patients with such critical diseases. However, safe and efficient therapeutic strategies targeting circulating histones are lacking in current clinical practice.

Introduction: Periampullary diverticulum (PAD) is frequently discovered in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Studies have yielded conflicting results regarding its impact on the technical success of ERCP and post-ERCP complications.
Aim: This study aims to assess the success and safety of ERCP in patients with PAD.
