Nonalcoholic Fatty Liver Disease and Diabetes Mellitus Are Associated With Post-Transjugular Intrahepatic Portosystemic Shunt Renal Dysfunction: An Advancing Liver Therapeutic Approaches Group Study.

Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for portal hypertensive complications, but its effect on renal function is not well characterized. Here we describe renal function and characteristics associated with renal dysfunction at 30 days post-TIPS. Adults with cirrhosis who underwent TIPS at 9 hospitals in the United States from 2010 to 2015 were included.

Increased fat in pancreas not associated with risk of pancreatitis post-endoscopic retrograde cholangiopancreatography.

Background: A preliminary study has shown increased pancreatic fat in patients with idiopathic pancreatitis and sphincter of Oddi dysfunction. In this study, we aimed to determine if an increased quantity of pancreatic fat is an independent risk factor for pancreatitis post-endoscopic retrograde cholangiopancreatography (ERCP).

Methods: In this case control study, we retrospectively reviewed a local radiological and ERCP database to identify patients who had had abdominal magnetic resonance imaging (MRI) followed by ERCP no more than 60 days later between September 2003 and January 2011.

Current and past cigarette smoking significantly increase risk for microscopic colitis.

Background: Cigarette smoking is an important environmental factor affecting inflammatory bowel disease. The role of smoking has not been rigorously studied in microscopic colitis (MC). The aim of this study was to compare the association of cigarette smoking in individuals with MC compared to a control population without MC.

Decreased colorectal cancer and adenoma risk in patients with microscopic colitis.

Introduction: Microscopic colitis is currently considered to harbor no increased risk for colorectal cancer, based on a few small studies with limited long-term follow-up. Our aim was to identify patients with microscopic colitis, and to compare long-term rates of colorectal cancer or adenoma to a control group of patients without microscopic colitis.

Methods: We reviewed the records of patients diagnosed with microscopic colitis, as identified by a hospital-based pathology database from January 2000 to August 2008.

Incidence and risk factors for lymphoma in a single-center inflammatory bowel disease population.

Aims: Previous studies on the risk of lymphoma in inflammatory bowel disease (IBD) have yielded conflicting results. We aim to determine the incidence and risk factors for lymphoma in a large IBD population.

Methods: Patients with lymphoma were identified from a single-center IBD database.
