Fully-covered metal stent for the treatment of post-percutaneous transhepatic biliary drainage (PTBD) obstruction due to a blood clot in the common bile duct: a case report.

Aim: This study aimed to report a case of a fully-covered metal stent for the treatment of post-Percutaneous Transhepatic Biliary Drainage (PTBD) obstruction caused by a blood clot in the common bile duct (CBD).

Case Presentation: The case involved a 75-year-old man who had a history of recurring upper abdominal pain and jaundice. The result of an abdominal computerized tomography showed a stricture in the CBD.

Obesity promotes gastric cancer metastasis via diacylglycerol acyltransferase 2-dependent lipid droplets accumulation and redox homeostasis.

Experimental and molecular epidemiological studies indicate important roles for adipose tissue or high-fat diet (HFD) in tumor growth and metastasis. Gastric cancer (GC) possesses a metastatic predilection for the adipocyte-rich peritoneum. However, the precise molecular relevance of HFD in the peritoneal metastasis of GC remains unclear.

Proliferative ductular reactions correlate with hepatic progenitor cell and predict recurrence in HCC patients after curative resection.

Background: Ductular reactions (DRs) are well documented in many acute and chronic liver disease.The DRs are thought to be the transit amplifying cells deriving from activation of the stem/progenitor cell compartments of the liver. The aim of this study was to examine the presence of proliferative index of DR (PI-DR) and HPC markers' expression in HCCs after curative hepatectomy, as well as their relationship with clinicopathological features and prognosis.

Identification and differential expression of human carcinoma-associated antigens in hepatocellular carcinoma tissues.

This study was designed to identify and verify hepatocellular carcinoma (HCC)-associated human carcinoma antigens (HCAs) that may be useful as tumor markers for HCC. We found that BCE075 and BCD021 anti-HCA antibodies were immunostained in the liver tissue samples and showed specific staining. Their expression was increased in HCC compared with normal liver tissues (P = 0.

Endoscopic stenting for post-transplant biliary stricture: usefulness of a novel removable covered metal stent.

Background: Endoscopic management of biliary anastomotic stricture (AS) following liver transplantation (LT) remains challenging. There are no dedicated self-expandable metal stents (SEMS) for this setting.

Methods: A short fully covered SEMS (FCSEMS) with a retrieval suture was designed.

Oncogenic potential of retinoic acid receptor-gamma in hepatocellular carcinoma.

Retinoic acid receptors (RAR; alpha, beta, and gamma), members of the nuclear receptor superfamily, mediate the pleiotropic effects of the vitamin A metabolite retinoic acid (RA) and derivatives (retinoids) in normal and cancer cells. Abnormal expression and function of RARs are often involved in the growth and development of cancer. However, the underlying molecular mechanisms remain largely elusive.
