Post-endoscopic Retrograde Cholangiopancreatography Air Leak Syndrome: An Overview of Current Perspectives

Abstract

Post-endoscopic retrograde cholangiopancreatography (ERCP) air leak (PEAL) syndrome is a rare complication that includes pneumothorax, pneumomediastinum, pneumoperitoneum, air embolism, and subcutaneous emphysema. A 71-year-old female diagnosed with mild acute biliary pancreatitis, who underwent ERCP for stone retrieval developed neck, chest, and abdominal pain, as well as swelling of the neck, along with crepitus all along the neck and face. CT scan showed pneumoperitoneum, pneumomediastinum, and subcutaneous emphysema. The patient was diagnosed as a case of PEAL syndrome, and was managed conservatively. She ultimately underwent an uneventful cholecystectomy with peroperative stone retrieval. PEAL syndrome, albeit rare, can be a potentially life-threatening complication following ERCP, which requires continuous monitoring. It may be managed conservatively, endoscopically, or surgically.
