Gastrointestinal imaging 2: liver, spleen, pancreas, adrenals, biliary tract and aorta
Published in Sarah McWilliams, Practical Radiological Anatomy, 2011
ERCP (endoscopic retrograde cholangiopancreatography) is performed to assess the pancreatic and bile ducts. Due to its invasive nature, ultrasound and then magnetic retrograde cholangiopancreatography (MRCP) are used initially or to assess the ducts. ERCP is indicated only for therapeutic or interventional procedures such as dilatation of the sphincter of Oddi, for stone extraction and stent insertion, unless MRI is contraindicated when MRCP cannot be performed.

Endoscopic retrograde cholangiopancreatography (ERCP) is used increasingly for diagnosis and treatment of pancreatobiliary diseases, including choledocholithiasis, gallstone pancreatitis, and bile duct or pancreatic duct stenosis [1]. Bacterial infection is the most morbid complications of ERCP, which can cause ERCP-related death through septic cholangitis, liver abscess, acute cholecystitis, and pancreatic pseudocyst [2]. During the procedure, bacteria can enter the biliary tract and colonize this tissue via contaminated device and its related instruments [3]. Difficulty in reprocessing, cleaning and disinfection of duodenoscopes, such as elevator mechanism, converted this medical device as a reservoir for life-threatening infections. The infection in this organ causes more frequently through enteric bacterial flora [4]. Several outbreaks were reported in association to used contaminated endoscopes during ERCP procedure in recent years [5–11]. Although these outbreaks were mainly related to Pseudomonas aeruginosa, Klebsiella spp., Enterococcus spp., Escherichia coli, and Staphylococci, sources of these bacteria and their transmission routes were not well characterized.
