Prospective Evaluation of the Clinical Utility of Pseudocyst Drainage With Metal Stent

Technical Success of Endoscopic Ultrasound-guided Single-access Pseudocyst Drainage With a Fully Covered Self-expanding Metal Stent ; Anchored With a Double Pigtail Plastic Stent Inserted Through the Metal Stent Lumen

Time Frame: baseline

Technical success was evaluated by the ability to achieved pseudocyst drainage after endoscopically placing a Fully Covered Self-expanding Metal Stent in the pseudocyst . Technical failure was evaluated by the inability to fully drain the pancreas pseudocyst after endoscopically placing a Fully Covered Self-expanding Mental Stent in the pseudocyst.
