Endoscopic retrograde cholangiopancreatography (ERCP) has become a commonly performed endoscopic procedure for the diagnosis and treatment of pancreatobiliary disease. ERCP is a relatively safe procedure. However, there are chances of potentially severe complications such as pancreatitis, hemorrhage, infection and perforation. Duodenal perforation is an uncommon, but serious complication of ERCP, and this has occurred in 0.3 to 1.1% of most of the previous series. There are various clinical course and treatments depending on the cause of perforation. However, the development of pneumothorax in patients undergoing ERCP is rare. There are no reports of tension pneumothorax complicating ERCP in Korea. We experienced a case of tension pneumothorax with complicating duodenal microperforation following ERCP, and the patient (a 77 year old female with suspicious dysfunction of the sphincter of Oddi) was treated with conservative treatment.
