Interpreting studies comparing lumen-apposing metal stents and plastic stents for walled-off necrosis: wisdom is the need of the hour

Lumen-apposing metal stents (LAMSs) are being increasingly used for the drainage of walled-off necrosis (WON). It was postulated that their placement, compared with plastic stents, is technically easier, decreases the need for necrosectomy, lowers adverse events, enables faster disease resolution, and is potentially more cost effective. However, with the exception of shorter procedural duration, other perceived advantages have not been borne out in randomized trials [1].
