Efficacy and safety assessment of ERCP in patients with malignant biliary obstruction.

Background: To assess the efficacy and safety of Endoscopic retrograde cholangiopancreatography (ERCP) for malignant biliary obstruction (MBO).

Material And Methods: A review of all ERCP-procedures performed at Akershus University Hospital during the six year period between 2009-2014 was analysed. Data for the period 2009- 2013 were obtained retrospectively and prospectively for 2014.

Components of treatment delay in rheumatoid arthritis differ according to autoantibody status: validation of a single-centre observation using national audit data.

Objective: To determine whether time to treatment following symptom onset differs between RA patients according to autoantibody status.

Methods: A single-centre retrospective analysis of a UK early RA inception cohort was first undertaken to identify those components of the patient journey that differed by serological subtype. Data from a UK national audit of early inflammatory arthritis patients was accessed to replicate the key finding.
