Drainage of Complex Walled-Off Pancreatic Fluid Collections in LAMS Era: A Multicenter Study

Table 2

Procedural data and outcomes. Patients with WOPFCs requiring LAMS plus additional drainage methods including additional LAMS, percutaneous drainage, or surgical debridement were categorized as “complex WOPFCS” or classified as group A whereas ones requiring only single were grouped as “noncomplex WOPFCS” or group B.
