Metal stents for lumen apposition for EUS-guided drainage

AuthorsJong Ho Moon, MD from the Digestive Disease Center and Research Institute at SoonChunHyang University School of Medicine in Bucheon/Seoul, South Korea discusses this New Methods article “A newly designed fully covered metal stent for lumen apposition in EUS-guided drainage and access: a feasibility study (with videos)” from the June issue.

EUS-guided transenteric drainage by using a newly developed fully covered metal stent that is capable of lumen apposition was successfully performed in animal study and small sized clinical experiences. This stent is equipped in conventional delivery system, and preventive for migration and leak because of backwardly folded flanges in both ends and full covering of stent.

As EUS-guided therapeutic interventions have evolved, development of metal stents for safe and effective procedures is needed.

The EUS-guided drainage was successfully performed by using the new stent. There were no adverse events such as migration or leakage. Endoscopic interventions through the stent was immediately possible, and the stents were easily removed after 4 weeks in patients with pancreatic pseudocyst. Large scaled clinical studies are warranted.

Additional expected usage of this new stent is choledochoduodenostomy or temporary insertion into the gallbladder for formation of an access route to perform endoscopic interventions.
