Abstract
Endoscopic retrograde cholangiopancreatography is an endoscopic technique which nowadays plays an irreplaceable role in the diagnostics and mainly in the therapy of diseases of the biliary system and pancreas. Despite its unquestionable benefits, ERCP is a mini-invasive, highly specialized method with a risk of very serious complications.
Possible complications after therapeutic ERCP include perforation events. Although these complications are certainly not the most common ones, they seriously threaten the patient's life.
In our case report, we describe the origin of a perforation event after therapeutic ERCP, when the duodeno-biliary drainage (in a patient with stenosis of the bile duct) left the bile duct and perforated the small intestine. We treated the perforation using the OVESCO clip immediately after recognizing it and thereby solved the situation.
