COMPARISON OF OUTCOMES OF BI-FLANGED METAL STENT ALONE VERSUS BI-FLANGED METAL STENT WITH CO-AXIAL PLASTIC STENT FOR DRAINAGE OF WALLED-OFF PANCREATIC NECROSIS - A PROSPECTIVE RANDOMISED CONTROLLED STUDY.

Endoscopic ultrasound guided drainage of WON with metal stent is the mainstay of WON management. But there are few complications related to BFMS , like bleeding due to vessel erosion, stent clogging , stent migration . This study is to assess, whether placing an anchoring DPS through the BFMS will decrease adverse events or not. There are only 2 retrospective studies till date ,comparing LAMS with coaxial stent vs LAMS alone. one study showed no significant decrease in adverse events , one study showed decrease in adverse events when DPS with LAMS . But there has been no prospective RCT to assess the utility of DPS to date
