To evaluate a newly developed, fully covered, self-expandable metal stent (FCSEMS) customized for cystogastrostomy.
Retrospective case series.
Tertiary-care academic medical centers and affiliated hospitals.
Nine patients who underwent endoscopic treatment of PFCs (5 with pseudocysts and 4 with walled-off pancreatic necrosis).
Stent deployment after endoscopic US-guided puncture. Irrigation and necrosectomy were performed at the discretion of the endoscopist.
Technical and clinical success rate, complications, and removability.
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 % ).
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.
The endoscopic approach that uses this new FCSEMS is feasible for the treatment of PFCs. However, further evaluation is required.
