Endoscopic Ultrasound-Guided Self-Expandable Metal Stent Placement for the Treatment of Infected Pancreatic Pseudocysts

The standard endoscopic ultrasound (EUS) approach of cystogastrostomy involves the use of series of plastic pigtail stents that are placed through the wall of the cyst. The use of a single stent has also been described in the literature. Here we describe five cases of EUS-guided cystogastrostomy with irrigation of infected pancreatic pseudocysts using a single self-expandable metal stent (SEMS). To our knowledge this has not been described in the literature in the United States. This novice approach will have significant implications in the management of infected pseudocysts with a lower morbidity, mortality and overall cost compared to conventional management such as surgery or percutaneous drainage.
