Novel anti-reflux biliary metal stent with a distal tapered end for distal malignant biliary obstruction: a feasibility study.

We developed a self-expandable metallic stent (SEMS) with a distal tapered end to reproduce the physiological bile flow with a pressure gradient due to the difference in the diameter. We aimed to evaluate the safety and efficacy of the newly developed distal tapered covered metal stent (TMS) for distal malignant biliary obstruction (DMBO). This single-center, prospective, single-arm study was conducted in patients with DMBO.

Histological improvement in chronic hepatitis C-autoimmune hepatitis overlap syndrome by glecaprevir and pibrentasvir.

A 60-year-old man with type-2 diabetes and chronic hepatitis C (HCV) was diagnosed with single hepatocellular carcinoma (HCC) of 67 mm in the hepatic posterior right lobe. Lenvatinib 8 mg was initiated but discontinued because of grade 3 liver injury. The patient continued to have prolonged liver injury and persistently high immunoglobulin G levels.

Chemotherapy with gemcitabine for unresectable intrahepatic cholangiocarcinoma in a patient undergoing maintenance hemodialysis.

A 56-year-old man with chronic renal failure due to diabetic nephropathy had received maintenance dialysis (every 4 h, three times/week). A hypoechoic tumor measuring 67 × 50 mm in the right lobe of the liver was discovered following routine abdominal ultrasonography. Dynamic computed tomography showed a low-density liver tumor, enlarged hilar lymph node, and a small nodule on the dorsal side of the lower lobe of the left lung.
