BACKGROUND: The popularity of laparoscopic liver resection (LLR) is spreading, worldwide, because the intraoperative blood loss is less than for open hepatectomy and it is associated with a shorter hospitalization period [1-6]. During LLR, intraoperative hemostasis is difficult to achieve, unlike during laparotomy where bleeding can be stopped instantly [7-10]. Our LLR method for the treatment of hepatocellular carcinoma (HCC) includes maximal control of intraoperative bleeding using a monopolar soft-coagulation device...

INTRODUCTION: Neuroendocrine tumors (NETs) of the extrahepatic bile ducts are extremely rare neoplasms arising from endocrine cells and have variable malignant potential. They most commonly occur in young females and usually present with painless jaundice. PRESENTATION OF CASE: Here we present the case of an asymptomatic 57-year-old woman with NET of the common bile duct that was incidentally discovered on abdominal ultrasound during a medical examination. She was admitted to our hospital with a diagnosis of hepatic hilar tumor...

We report a case of a mucin-producing intraductal papillary neoplasm of the intrahepatic bile duct (M-IPNB) diagnosed over a period of 6 years. A 64-year-old man underwent follow-up evaluations for an abdominal aortic aneurysm at our hospital. In 2009, a computed tomography (CT) scan revealed a simple hepatic cyst in segment 3 of the liver. Annual CT scans initially showed almost no change in the size or shape of the cyst. The cystic lesion, which measured 5 cm in 2014, had increased to 11 cm by 2015, and a solid component was detected within the cyst...

Cholangiocarcinoma (CCA) is an aggressive, metastatic bile duct cancer. CCA is difficult to diagnose, and responds poorly to current radio- and chemo-therapy. Piperlongumine (PL) is a naturally-occurring small molecule selectively toxic to cancer cells by targeting reactive oxygen species (ROS). In this study, we demonstrated the potential anticancer activity of PL in CCA. PL markedly induced death in CCA cell lines in a dose- and time-dependent manner through the activation of caspase-3 and PARP. PL also stimulated ROS accumulation in CCA...

Metastatic carcinomas of the ovary have an important place in all ovarian cancers and tumors. They can originate from many organs and systems and may metastasize to the ovary. The most common primary origin of metastasis is the gastrointestinal tract and then breast tissue. Cholangiocellular carcinomas involving the junction of the right and left bile ducts are called Klatskin tumors, and their metastases to the ovaries are very rare. A woman aged 54 years who had been treated previously for Klatskin tumor was admitted to our clinic due to bilateral ovarian masses and high serum calcium 19-9 levels...

Extrahepatic bile duct carcinoma is a potentially malignant gastrointestinal lesion. Cancer cells spread via the lymphatic system to regional lymph nodes and help in tumor progression. However, there are no reports on the prognostic impact of extracapsular lymph node invasion and myofibroblastic activity in this cancer. Hence, we classified the histopathologic patterns of lymph nodes into 2 patterns: extracapsular lymph node invasion or not. Based on this, we investigated 32 cases of extrahepatic bile duct cancer with lymph node metastasis and classified 21 cases as positive and 11 cases as negative...

Altered bile acid (BA) signaling is associated with hepatotoxicity. The farnesoid X receptor (FXR) is a nuclear receptor that transcriptionally regulates BA homeostasis. Mice with FXR ablation present hepatocarcinoma (HCC) due to high toxic BA levels. Mice with Abcb4 ablation accumulate toxic BA within the bile ducts and present HCC. We have previously shown that intestinal specific activation of FXR by transgenic VP16-FXR chimera is able to reduce BA pool size and prevent HCC. Here we tested chemical FXR activation by administering for 15 months the dual FXR/ membrane G protein-coupled receptor (TGR5) agonist INT-767 (6α-ethyl-3α,7α,23-trihydroxy-24-nor-5β-cholan-23-sulphate) to Fxr(-/-) and Abcb4(-/-) mice...

The polysaccharide chitosan has abundant cationic amine groups, and can form ion-complexes with anionic molecules such as the strong photosensitizer chlorin e6 (Ce6). In this study, water-soluble chitosan (WSC) was used to fabricate Ce6-incorporated nanophotosensitizers (Abbreviated as ChitoCe6 nanophotosensitizer) via a self-assembling process. This was accomplished by dissolving WSC in pure water and then directly mixing the solution with solid Ce6 causing ion complex formation between WSC and Ce6. The resulting nanophotosensitizer was spherical in shape and had a particle size of less than 300nm...

BACKGROUND: "Hilar en bloc resection" using a no-touch technique has been advocated as a standard procedure in right-sided hepatectomies for treatment of perihilar cholangiocarcinoma (PHC). In principle, it has never been reported for left-sided tumors. The aim is to describe the procedures of total hilar en bloc resection with left hemihepatectomy and caudate lobectomy (THER-LH) for advanced PHC and discuss feasibility and clinical significance of this novel technique. METHODS: A retrospective study using a prospectively maintained database was performed to identify eight patients who had received THER-LH for advanced PHC from January 2013 to December 2015...

Bilirubin (BR), a bile pigment that exerts potent antioxidant and anti-inflammatory effects, is also a major constituent of black pigment gallstones found in bile ducts under certain pathological conditions. Inspired by the intrinsic metal-chelating power of BR found in gallstones, here we report a cisplatin-chelated BR-based nanoparticle (cisPt@BRNP) for use as a new photonic nanomedicine for combined photoacoustic imaging and photothermal therapy of cancers. The cisPt@BRNPs were prepared by simply mixing cisplatin with BRNPs, yielding ~100-nm-size nanoparticles...

Breast cancer is the most common tumor in women and the first cause of death for malignancy in the female. Bile ducts are not among the common sites of metastasis from breast cancer. Few cases of obstructive jaundice due to metastatic breast cancer have been described in the literature and they mostly resulted from widespread liver metastases that eventually involved the bile ducts. We report an exceptional case of ampullary metastasis in the absence of liver metastases. Sporadic reports have been published about the involvement of the ampulla by breast cancer metastasis...

ETHNOPHARMACOLOGICAL RELEVANCE: Liuweiwuling (LWWL) tablets contain a six-herb Chinese formula and are commonly prescribed to facilitate nourishment of the liver and kidneys, clear away toxic materials and activate blood circulation. Administration of LWWL is well known for its protective effects on the liver and its capacity to confer long-term stability in patients exhibiting reduced transaminase levels. Clinical studies have reported that LWWL can also be used for the treatment of liver fibrosis with associated treatment regimens resulting in a concomitant reduction in transforming growth factor β1 (TGF-β1) levels in the serum of patients with hepatic fibrosis...
