Reducing the Incidence and Severity of Post Ercp Pancreatitis

Abstract

Acute pancreatitis remains the commonest complication of ERCP (endoscopic retrograde cholangiopancreatography) with published incidence rates that have changed little over 30 years despite significant advances in endoscope and ERCP accessory technology and the introduction of structured ERCP training. Technique related risk factors for post ERCP pancreatitis have been recognised for many years and have been recently refined via large prospective audits. These studies have also revealed the importance of patient related factors and highlighted the high incidence of post ERCP pancreatitis in women being investigated for acalculus biliary pain or idiopathic recurrent acute pancreatitis. Sphincter of Oddi hypertension is often found to be present in this group of patients. Methods of preventing post ERCP pancreatitis have been sought for many years and numerous drugs have been tried using a variety of regimes with heterogeneous groups of patients. At present pancreatic duct stenting looks to be the most efficacious prophylactic method but is not for the beginner endoscopist. It is possible, however, by using a simple strategy to minimise the incidence of post ERCP pancreatitis and modulate its severity.
