title: Preliminary report on a new, fully covered, metal stent designed for the treatment of pancreatic fluid collections.
abstract: BACKGROUND
  Endoscopic transluminal treatment of pancreatic fluid collections (PFC) has been reported as an effective alternative approach to surgical treatment. A wide, short stent with an anti-migration system has been developed.
  
  
  OBJECTIVE
  To evaluate a newly developed, fully covered, self-expandable metal stent (FCSEMS) customized for cystogastrostomy.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  Tertiary-care academic medical centers and affiliated hospitals.
  
  
  METHODS
  Nine patients who underwent endoscopic treatment of PFCs (5 with pseudocysts and 4 with walled-off pancreatic necrosis).
  
  
  METHODS
  Stent deployment after endoscopic US-guided puncture. Irrigation and necrosectomy were performed at the discretion of the endoscopist.
  
  
  METHODS
  Technical and clinical success rate, complications, and removability.
  
  
  RESULTS
  The FCSEMS was inserted successfully in all cases (9/9, 100%). Clinical success was achieved in 7 of 9 cases (77.8%). No early complications associated with the procedure were observed. Late complications were observed in 2 cases (bleeding and asymptomatic migration). The FCSEMS was removed without any complications in all 6 cases where it was attempted after the procedure had been completed (100%).
  
  
  CONCLUSIONS
  This was a retrospective evaluation of a small number of cases. The FCSEMS was always inserted via the transgastric route. Follow-up duration was short.
  
  
  CONCLUSIONS
  The endoscopic approach that uses this new FCSEMS is feasible for the treatment of PFCs. However, further evaluation is required.
