Performance of two-dimensional shear wave elastography and transient elastography compared to liver biopsy for staging of liver fibrosis.

Background: Staging of liver fibrosis traditionally relied on liver histology; however, transient elastography (TE) and more recently two-dimensional shear wave elastography (2D-SWE) evolved to noninvasive alternatives. Hence, we evaluated the diagnostic accuracy of 2D-SWE assessed by the Canon Aplio i800 ultrasound system using liver biopsy as reference and compared the performance to TE.

Methods: In total, 108 adult patients with chronic liver disease undergoing liver biopsy, 2D-SWE and TE were enrolled prospectively at the University Hospital Zurich.

Non-invasive tools for compensated advanced chronic liver disease and portal hypertension after Baveno VII - an update.

Non-invasive tests (NITs) and liver stiffness measurement (LSM) in particular, have entered clinical practice over 20 years ago as point-of-care tests to diagnose liver fibrosis in patients with compensated chronic liver disease. Since then, NITs use has evolved thanks to a large number of studies in all major etiologies of liver disease, and they have become important tools to stratify the risk of portal hypertension and liver-related events. The Baveno VII consensus workshop provided several novel recommendations regarding the use of well-established and novel NITs in the specific setting of portal hypertension screening, diagnosis and follow-up.

Assessment of hepatic fibrosis and inflammation with look-locker T1 mapping and magnetic resonance elastography with histopathology as reference standard.

Purpose: To compare the diagnostic performance of T1 mapping and MR elastography (MRE) for staging of hepatic fibrosis and grading inflammation with histopathology as standard of reference.

Methods: 68 patients with various liver diseases undergoing liver biopsy for suspected fibrosis or with an established diagnosis of cirrhosis prospectively underwent look-locker inversion recovery T1 mapping and MRE. T1 relaxation time and liver stiffness (LS) were measured by two readers.

Health-related quality of life and functional disorders after diverticular surgery.

Diverticulosis and diverticulitis are leading indications for colorectal surgery in Western countries. Abdominal pain, functional disorders, and low health-related quality of life (HRQoL) can limit the outcome of abdominal surgery even in the absence of complications. Therefore, we aimed to review current evidence on postoperative long-term outcomes including HRQoL, functional disorders, abdominal pain, and patients' satisfaction after diverticular surgery for diverticulosis/diverticulitis.

Association between proton-pump inhibitors and the risk of gastric cancer: a systematic review with meta-analysis.

Introduction: The use of proton-pump inhibitors (PPI) may be associated with an increased risk of gastric cancer (GC).

Objective: To review and meta-analyse available literature investigating the association between PPI use and GC risk.

Methods: Two independent reviewers systematically searched Ovid MEDLINE, EMBASE, and Cochrane Library (inception to July 2020) for case-control and cohort studies assessing the association between PPI use and GC according to a predefined protocol in PROSPERO (CRD42018102536).
