Endoscopic ultrasound-guided hepaticogastrostomy vs. antegrade metal stent placement kee** an access route in patients with malignant biliary obstruction
Few studies have compared endoscopic ultrasound (EUS)-guided hepaticogastrostomy (HGS) with EUS-guided antegrade metal stent placement (AGMS). The purpose of this study was to compare times to recurrent biliar...

Safety of skip** the tract dilation step for EUS-guided biliary drainage in patients with unresectable malignant biliary obstruction (with video)
Thin delivery system stents can be inserted directly without the need for a tract dilation step and are expected to reduce bile leakage during endoscopic ultrasound-guided biliary drainage (EUS-BD). The presen...

Impact of sarcopenia on recurrent biliary obstruction after EUS-guided biliary drainage in patients with malignant biliary obstruction
Sarcopenia is an important prognostic factor for cancer patients. The aim of this study was to assess the ability of sarcopenia to predict recurrent biliary obstruction (RBO) in patients with unresectable canc...

Successful removal of an internal pancreatic stent that migrated into the bile duct using double-balloon enteroscopy after pancreaticoduodenectomy
Internal stents used during pancreaticoduodenectomy (PD) are generally spontaneously passed through the rectum by defecation. However, we encountered six patients with internal stents that migrated into the bi...
