Core Tip

Core tip: Duodenal perforation is a rare complication of endoscopic retrograde cholangiopancreatography (ERCP) with potentially life-threatening consequences. Early diagnosis and management is key to reducing patient morbidity and mortality, yet intraoperative detection of periampullary perforations is difficult even with video-equipped endoscope systems. In our 71-mo experience of performing ERCP, only six perforation cases occurred, five of which were undetected by intraoperative video endoscopy and required digital fluoroscopy for detection. Thus, fluoroscopic detection of retroperitoneal free air or contrast medium leakage can aid in intraoperative diagnosis and timely management of ERCP-related perforations.
