A novel fully covered metal stent for unresectable malignant distal biliary obstruction: results of a multicenter prospective study Open
Background/Aims: Endoscopic self-expandable metal stent (SEMS) placement is currently the standard technique for treating unresectable malignant distal biliary obstructions (MDBO). Therefore, covered SEMS with longer stent patency and fewe…

Endoscopic cyanoacrylate injection with gel immersion method improved the visual field in profuse gastric variceal hemorrhage Open
Endoscopic cyanoacrylate injection is recommended for gastric variceal hemorrhage (GVH) as a means of achieving urgent endoscopic hemostasis [1] [2]. However, it can sometimes be technically difficult to secure the visual field because GVH…

A case report of pancreatic neuroendocrine carcinoma diagnosed by EUS-FNA Open
症例は73歳男性.膵体部腫瘤の精査目的で入院した.造影CTでは尾側膵管の拡張を伴う境界明瞭な30mmの乏血性腫瘤であった.EUSでは境界が明瞭,辺縁はやや不整で,内部エコー均一な低エコー腫瘤として描出された.膵神経内分泌癌が疑われたが,通常型膵管癌との鑑別が困難であった.同腫瘤に対してEUS-FNAを行い,小細胞型神経内分泌癌と診断した.MRIで肝内に多発する結節を認めたため,多発肝転移を伴う膵神経内分泌癌と診断し,Irinotecan+Cisplatinのレジメンで化学療…
