Post-endoscopic retrograde cholangiopancreatography pneumomediastinum caused by probing a pseudopapilla: Case report of a rare complication treated conservatively

Abstract

Introduction:Pneumomediastinum and subcutaneous emphysema have rarely been reported to occur as a result of duodenal perforation from Endoscopic retrograde cholangiopancreatography (ErcP) and sphincterotomy. case report: In this report, we describe a case of pneumomediastinum associated with ErcP. there was no evidence of duodenal or esophageal perforation on imaging and the patient was treated conservatively with full recovery. conclusion: In the absence of frank perforation, pneumomediastinum and subcutaneous emphysema are rare complications of ErcP that can be managed conservatively with fasting, intravenous fluids and antibiotics.
