We aimed to compare the technical and clinical success and the safety profile of 2 endoscopic techniques used for the treatment of malignant gastric outlet obstruction: placement of a duodenal self-expandable metal stent (D-SEMS) versus EUS-guided gastroenterostomy (EUS-GE).
Treatment of malignant gastric outlet obstruction in a minimally invasive fashion remains a challenge. Improvements in survival of gastric and pancreatic tumors in recent years make this issue more relevant.
Although standard endoscopic treatment with D-SEMSs is associated with good results, its long-term performance still has some room for improvement because of its elevated rate of stent malfunction. It has been hypothesized that EUS-GE that avoids traversing the tumor may theoretically provide longer durability. However, this point is yet to be proven.
The current study represents a large multicenter experience with D-SEMSs and EUS-GE. The message we should take from this study is that, even in the early stage of the learning curve for EUS-GE, this new EUS-guided approach has the same technical success and safety profile as the D-SEMS approach.
Initial clinical success appears to be similar for both techniques, but stent patency was longer in the EUS-GE group, and differences were significant at 3 months. Comparative studies focusing on stent patency and cost-effectiveness are warranted.
Nonetheless, EUS-GE to palliate malignant gastric outlet obstruction is a promising technique.
