Table 1 Comparative table of the two kinds of stents used in transmural drainage of pancreatic collections
Lumen-apposing metal stent | Plastic | ||
|---|---|---|---|
Advantages | Disadvantages | Advantages | Disadvantages |
Easy release | Expensive | Economical | Smaller diameter |
Wide diameter | Less scientific evidence | Easy extraction | Shorter patency |
Better drainage of solid waste and necrosis | Temporary placement | May be left permanently in place | High occlusion rate |
Direct necrosectomy via stent | Traumatism caused by the ends | Greater experience (studies) | A single stent is not enough for WON |
Longer patency | Not known whether permanent placement is possible | High success rate (> 80–90%, all types of collections) | Multiple > demanding technique (MTGT for WOPN) |
Correct visibility | Worse visibility (fluoroscopy) | ||
Short therapeutic time | |||
Hemostatic effect | |||
Prevents migration | Leakage of liquid (in ostomy) | ||
Anchoring effect | |||
Prevents liquid leakage | Migration | ||
Easy extraction | |||
