Prospective multicenter evaluation of moving cell metallic stents in endoscopic multiple stent deployment for hepatic hilar obstruction.

Background And Aim: Bilateral stent deployment for malignant biliary obstruction (MHBO) can be achieved using side-by-side (SBS) or stent-in-stent (SIS) procedures. Compared with SBS techniques, the procedural steps of SIS are technically complex due to the necessity of introducing the delivery system into a contralateral biliary tract through the mesh of the SEMS. To overcome this issue, a novel uncovered SEMS, the HILZO Moving Cell Stent (MCS) has been released.

[A case of transcatheter arterial embolization for reduction of a hemorrhagic rectal gastrointestinal stromal tumor].

A 91-year-old woman was referred to our hospital with a primary complaint of hematochezia. A rectal submucosal tumor and an acute hemorrhagic rectal ulcer were noted on colonoscopy. After hemostasis was achieved with APC, the patient was diagnosed with a GIST by EUS-FNA.

[A case of erythropoietic protoporphyria with severe liver dysfunction].

A 27-year-old man was admitted to our hospital for evaluation and treatment of liver dysfunction with jaundice and hepatosplenomegaly. The patient had severe photosensitivity from childhood. Upper gastrointestinal endoscopy revealed mild esophageal varices.
