BACKGROUND AND STUDY AIM
Despite high technical and functional success rates with endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), rates of adverse events have also been high. No reports have focused on EUS-HGS alone with a large sample size about predictors of stent patency. The present study examined predictors of stent patency in patients who underwent EUS-HGS.

PATIENTS AND METHODS
The consecutive 51 patients who underwent EUS-HGS using one metallic stent were retrospectively enrolled in this study. Baseline characteristics, stent length from the hepatic portion and in the luminal portion, kinds of stent dysfunction, and stent patency were reviewed.

RESULTS
Median duration of stent patency was significantly shorter with stent length in the luminal portion <3?cm (52?days) than with =3?cm (195?days; P?
CONCLUSION
In conclusion, to obtain long-term stent patency, our data suggest that a stent length =3 cm in the luminal portion may be suitable for EUS-HGS.
