Isolated Pneumoperitoneum Following Endoscopic Retrograde Pancreatocholangiography – A Case Report and Literature Review

Purpose: Endoscopic retrograde cholangiopancreatography (ERCP) has several recognised risks include bleeding, perforation and pancreatitis. Isolated pneumoperitoneum (IP) is a rare complication of ERCP with an uncertain clinical significance which lacks established guidelines for management. We present a contemporary review of the literature documenting this phenomenon, in addition to our own novel case. Our aim is to summarise the demographics, presentation, management and recovery of these patients in order to shed further light on potential risk factors and pathophysiology.
