Life-threatening duodenal perforation complicating endoscopic retrograde cholangiopanceatography: A case series

Bilateral pneumothorax: The cause of hypoxia during endoscopic retrograde cholangiopancreatography

Background:

Endoscopic retrograde cholangiopancreatography (ERCP) is recognized as a significant diagnostic and therapeutic procedure for the administration of different pancreatic and biliary problems. This procedure runs a considerable risk of complications despite its substantial safety. The rate of significant inconveniences is reported to range from 5.4% to 23.0% and the general mortality from 0.1 to 1%. Post-ERCP pneumothorax is an uncommon complication that is usually underestimated

Case Presentation:

In the present study, we report a 65-year-old woman who develops hypoxemia during the ERCP. Based on the obtained results, it was revealed that this patient had perforation-related bilateral pneumothorax and hypoxemia.

Conclusion:

Based on the obtained results, it was revealed that this patient had perforation-related bilateral pneumothorax and hypoxemia.

A rare clinical presentation of third part duodenal perforation due to post-endoscopic retrograde cholangiopancreatography stent migration on advanced stage peri-ampullary tumor

As a diagnostic and therapeutic treatment role on malignant biliary obstruction, endoscopic retrograde cholangiopancreatography (ERCP) has already been used as a routine procedure, especially for palliative treatment on advanced stage peri‐ampullary tumor. This minimal invasive procedure has many early or late complications such as bleeding, post‐ERCP pancreatitis, perforation, cholangitis, and the rare duodenal perforation from the stent migration. The current review reported the incidence of stent erosion associated with duodenal perforation was only 1% for this palliative procedure. We report a 75 years old male patient with diffuse abdominal tenderness 7 days after palliative ERCP stent placement for malignant biliary obstruction, metal stent could not be placed, and plastic stent placement had been done. There was no post‐ERCP pancreatitis found during the first 24 h. The patient came to the emergency with clinical sign and symptoms of diffuse peritonitis; abdominal X‐ray found no free intraperitoneal air. Exploratory laparotomy was performed, and we found bile leak from the third part of perforated duodenal with 5 mm in diameter, plastic stent exposed from the perforation site, and no active bleeding. We performed primary suture of the duodenum, cholecysto‐enteric bypass, pyloric exclusion, gastro‐jejunostomy bypass, and braun anastomosis. Jejunostomy feeding has been placed. There were no postoperative cardiopulmonary complication, and the patient could tolerate well for oral intake and discharged from hospital at 10th postoperative day (POD). This rare duodenal perforation complication could happen even in plastic stent placement during the ERCP procedure, and early management was needed to gain the favorable outcome.
