Abstract null null Background/Objectives null Alcohol is the most common etiology of recurrent acute pancreatitis and chronic pancreatitis. The extent and timing of drinking that increases the transient risk of acute pancreatitis is yet unknown. null null null Methods null We designed a case-crossover study to determine the effective hazard period of drinking in relation to episodes of pancreatitis. We aim to evaluate the dose-response relationship between excess drinking and pancreatitis compar...

BACKGROUND Same-admission cholecystectomy (CCY) is recommended for mild acute biliary pancreatitis (biliary-AP). However, there is a paucity of research investigating reasons for early (30-day) unplanned readmissions in patients who undergo CCY for biliary-AP. Hence, we sought to investigate this gap using a large population database. METHODS Using the Nationwide Readmission Database (2010-2014), we identified all adults (age ≥ 18 years) with a principal diagnosis of biliary-AP who had undergone...

Summary null null Diabetes represents a group of diseases involving persistent hyperglycaemia. Exocrine disorders of the pancreas are increasingly recognised to cause or precede the onset of diabetes, which in this context is referred to as pancreatogenic or type 3c diabetes. Diabetes, as a sequela of acute pancreatitis, is observed across the spectrum of severity in acute pancreatitis and can be associated with other clinical complications. The pathophysiology of acute pancreatitis-related diab...

Background and study aims Endoscopic ultrasound (EUS)-guided tissue sampling is the standard of care for diagnosing solid pancreatic lesions. While many two-way comparisons between needle types have been made in randomized controlled trials (RCTs), it is unclear which size and type of needle offers the best probability of diagnosis. We therefore performed a network meta-analysis (NMA) to compare different sized and shaped needles to rank the diagnostic performance of each needle. Methods We sear...

OBJECTIVES There is a paucity of studies evaluating predictors of new-onset diabetes mellitus (DM) after acute pancreatitis (AP-related DM). We used a population-based database to evaluate predictors of AP-related DM. METHODS The Nationwide Readmissions Database (2010-2014) was used to identify all nondiabetic adults with an index primary diagnosis of AP. Multiple exclusions were applied to identify cohorts with and without AP-related DM. A case-control study was conducted to identify risk facto...

INTRODUCTION Existing laboratory markers and clinical scoring systems have shown suboptimal accuracies for early prediction of persistent organ failure (POF) in acute pancreatitis (AP). We used information theory and machine learning to select the best-performing panel of circulating cytokines for predicting POF early in the disease course and performed verification of the cytokine panel's prognostic accuracy in an independent AP cohort. METHODS The derivation cohort included 60 subjects with AP...
