The technique of ETD of PFCs using metal stents requires a series of steps including needle puncture, coiling of guidewire in the cyst cavity, balloon dilatation of the cystogastric tract, and finally, deployment of stent. With the availability of electrocautery-enhanced delivery systems, the deployment of metal stents can be achieved in a single step [64, 65]. Therefore, the drainage of PFCs using these "Hot Devices" is quicker and simpler. Currently, the electrocautery-enhanced delivery system is available with lumen apposing (Hot *AXIOS*) as well as biflanged metal stents (Hot *NAGI*).
