Outcomes of partially covered self-expandable metal stents with different uncovered lengths in endoscopic ultrasound-guided hepaticogastrostomy: a Japanese retrospective study

Abstract

Outcomes of partially covered self-expandable metal stents with different uncovered lengths in endoscopic ultrasound-guided hepaticogastrostomy: a Japanese retrospective study • No migrations were observed when using partially covered stents with �� mm uncovered portions.• They performed at least as well as those with � mm uncovered portions in all material respects.

Migration of covered expandable metal stents after endoscopic ultrasound-guided hepaticogastrostomy: stent covering versus stent design?

“… 2 This uncovered portion is embedded in the tissue and anchors the stent while allowing for drainage from other branches. In this issue of Clinical Endoscopy , Okamoto et al 3 examined the outcomes of patients undergoing EUS-HGS for malignant biliary obstruction using partially covered SEMS, whereby the internal portion (liver side) was uncovered for lengths of 5 mm or 20 mm. The patient outcomes were compared in terms of stent migration.…”
