Abstract

BACKGROUND/AIMS
Endoscopic ultrasound (EUS)-guided drainage of pancreatic fluid collections is a useful and effective procedure. One of the main limitations is the lack of devices tailored specifically for this technique. This study aims to evaluate a newly developed, fully covered, biflanged metal stent customized for EUS-guided transenteric drainage.
METHODS
We enrolled one dog in an animal study and six patients with pancreatic fluid (five with pancreatic pseudocysts and one with pancreatic walled-off necrosis) in a clinical study. We performed EUS-guided drainage of the pancreatic fluid or gallbladder using a newly developed metal stent. Study outcomes were technical and clinical success, adverse events, and stent removability.
RESULTS
In the animal study, the stent was placed successfully in the gallbladder via the EUS-guided transduodenal approach without complication. The cholecystoduodenal tract was intact on necropsy performed immediately after the procedure. The stents were inserted successfully and deployed in the six patients. There was no adverse event during or after the procedure.
CONCLUSIONS
EUS-guided transenteric drainage using a new fully covered, biflanged metal stent was technically feasible and was not associated with any serious adverse event. The tailored design of the flange at the end of the stent facilitated the effectiveness of the procedure.
