This research was supported by grants from the NIH (DK24031) and Mayo Foundation.. PY - 1998. Y1 - 1998. N2 - Bile duct epithelial cells, or cholangiocytes, proliferate in vivo under a number of pathologic (i.e., partial hepatectomy) and pathophysiologic (i.e., bile duct ligation, malignant transformation) conditions. However, little is known about the possible growth factors that modulate these proliferative responses, in part because an in vitro model to study proliferation of nontransformed, normal cholangiocytes is not available. ...
1. The effect of chronic bile-duct ligation on systemic and renal haemodynamics and on the capacity to dilute the urine was studied in conscious rats. Sham-operated rats served as controls.. 2. In the rats with bile-duct ligation, the maximal urinary diluting capacity was impaired, despite an expanded plasma volume, a normal mean arterial pressure and cardiac output, and normal intrarenal determinants of water excretion including distal delivery of fluid and function of the diluting segment.. 3. In contrast, maximal urinary dilution capacity was intact in rats with congenital central diabetes insipidus and chronic bile-duct ligation.. 4. It is concluded that the defect in urinary dilution in rats with chronic bile-duct ligation is dependent on antidiuretic hormone. ...

PhD ceremony: Ms. S. Op den Dries, 16.15 uur, Academiegebouw, Broerstraat 5, Groningen. Dissertation: Bile duct injury in liver transplantation. Study on etiology and the protective role of machine perfusion Promotor(s): prof. R.J. Porte, prof. J.A. Lisman. Faculty: Medical Sciences. Non-anastomotic biliary strictures (NAS) are a major complication after liver transplantation. The development of strictures (narrowing) of the bile ducts is characteristic of this complication, often leading to morbidity and the need for re-transplantation. The studies described in this thesis resulted in a better understanding of the causes of NAS and provide new strategies to prevent bile duct injury and the subsequent formation of NAS. The high incidence of NAS after donation after cardiac death (21-33%) compared to donation after brain death (1-13%), demonstrates the significant role of lack of oxygen (ischemia) in the development of NAS. In this thesis, severe injury to the bile duct epithelium (the lining of ...
Liver transplantation as an ultimate step in the management of iatrogenic bile duct injury complicated by secondary biliary cirrhosis - Article statistics #883221
Results Polycystic human and rat cholangiocytes displayed increased MMP activity, which was associated with increased mRNA levels of different MMPs. Interleukin (IL)-6 and IL-8, and 17β-oestradiol, all stimulated MMP activity in human cholangiocytes. The presence of antibodies against IL-6 and/or IL-8 receptor/s inhibited baseline MMP hyperactivity of polycystic human cholangiocytes but had no effect on normal human cholangiocytes. MMP-3 was overexpressed in cystic cholangiocytes from PCLD human and PCK rat livers by immunohistochemistry. Marimastat reduced MMP hyperactivity of polycystic human and rat cholangiocytes and blocked the cystic expansion of PCK cholangiocytes cultured in three-dimensions. Chronic treatment of 8-week-old PCK rats with marimastat inhibited hepatic cystogenesis and fibrosis.. ...
The major findings of these studies relate to the development and morphological, biochemical, molecular, and functional characterization of an animal model of selective bile duct damage that is restricted to large hormone-responsive ducts. In 1-wk BDL rats subsequently treated by gavage with a single dose of CCl4, we found that 2 days after CCl4 administration, the number of large (,15 μm in diam) bile ducts decreased. Consistent with the finding of bile duct loss limited to large ducts, 2 days after acute CCl4 treatment, apoptosis was detected in large ducts and cholangiocytes, respectively. DNA synthesis transiently decreased in large cholangiocytes. Inasmuch as large isolated cholangiocytes are localized in large bile ducts in BDL rats (1), the loss of proliferative capacity in large isolated cholangiocytes corresponds with the reduction of numbers of large ducts in 2-day CCl4-treated rats. Finally, consistent with CCl4-induced bile duct damage limited to large hormone-responsive ducts, ...
To evaluate ion transport mechanisms in bile duct epithelium (BDE), BDE cells were isolated from bile duct-ligated rats. After short-term culture pHi was measured with a single cell microfluorimetric set-up using the fluorescent pHi indicator BCECF, and calibrated with nigericin in high K+ concentration buffer. Major contaminants were identified using vital markers. In HCO3(-)-free media, baseline pHi (7.03 +/- 0.12) decreased by 0.45 +/- 0.18 pH units after Na+ removal and by 0.12 +/- .04 after amiloride administration (1 mM). After acid loading (20 mM NH4Cl) pHi recovery was inhibited by both Na+ removal and amiloride (JH+ = 0.74 +/- 1.1, and JH+ = 2.28 +/- 0.8, respectively, vs. 5.47 +/- 1.97 and 5.97 +/- 1.76 mM/min, in controls, respectively). In HCO3- containing media baseline pHi was higher (7.16 +/- 0.1, n = 36, P less than 0.05) and was decreased by Na+ substitution but not by amiloride. Na+ removal inhibited pHi recovery after an intracellular acid load (0.27 +/- 0.26, vs. 7.7 +/- 4.1 ...
Introduction: Bile duct injury (BDI) after cholecystectomy remains a serious complication with major implications for patient outcome. For most major BDIs, the recommended method of repair is a hepaticojejunostomy (HJ). We conducted a retrospective review from 5 Danish hepatobiliary centres aiming to examine the perioperative and the long-term outcome after reconstructive HJ ...
Different approaches to the treatment of bile duct injuries. According to the existing literature, endoscopic and/or radiologic management of BDI is feasible, whenever theres a continuity in bile duct and not a complete transection. These approaches can include an endoscopic retrograde cholangiography to drain bile ducts after sphincterotomy or placement of endoprosthesis [1]. Approach by an endoscopic retrograde cholangiography allows biliary stenting or balloon dilatation, considered to be the first-line treatment in some referral centres. Usually the placement of a 7 - 8.5 French single plastic stent is the first step in a series of endoscopic rehabilitation protocol. If a single stent is not effective, placement of multiple stents or a large-diameter stent can be selected [2]. Patients undergoing endoscopic stent treatment has shown a safe and favourable long term outcome, although no consensus has been reached regarding placement of one single stent alone or sequential insertion of ...

PY - 1996. Y1 - 1996. N2 - Sixteen Chinese children with cholestasis since early infancy were diagnosed to have paucity of interlobular bile ducts (PILED) or its equivalent. Twelve children belonged to the syndromic group of PILBD and four children belonged to the non-syndromic group. A definite histological diagnosis of bile duct paucity was established in only two children (aged 4 and 9 months) during the first percutaneous needle biopsy. In the remaining 14 children a varying degree of bile duct destruction was evident in the follow up percutaneous or wedge liver biopsies. The evolving changes were characterized by inflammatory infiltration near or at the ductal wall, the presence of dysmorphic ductules, the degeneration of ductal epithelia and a progressive decrease of interlobular bile ducts. Of 10 ...

Interpretive Summary: The study presents a method for the selective in vitro culture, i.e., in the petri dish, of pig hepatocytes and bile duct cells, i.e., liver cells. The report characterizes the cells general health and typrical in vivo-like, i.e., in the body-like, appearance and functions. Also, presented are data on specific liver gene expression and liver serum-protein production that again show that the hepatocytes and bile duct cell cultures are similar to liver cells found in a pigs own liver. For agricultural purposes, because the liver is so important to the growth and maintenance of the pig, this in vitro model could be useful for testing man-made genetic changes to the liver function of pigs prior to the actual genetic engineering of the pig, ...
Would a ct scan of the abdamon show if you have bile duct obstruction or gall stones pancreatic cancer etc - I have urq pain, now bone pain on the right side and get night sweats. Can a CT scan always pick up pancreatic or bile duct cancer? No test is perfect! No test is 100 percent accurate. Although a multiphase ct with contrast is a very good test for pancreatic or bile duct cancer, it is not a perfect test. Mri, mrcp and ERCP are all tests that may be useful. Generally, imaging for this problem begins with a ct, with the additional tests based on the ct results, as well as lab tests and other examinations.

We have recently demonstrated that rat cholangiocytes express both estrogen receptors (ER)-α and -β subtypes, while hepatocytes only express ER-α. ER and especially the ER-β subtype, are overexpressed in cholangiocytes proliferating after bile duct ligation (BDL) in the rat, in association with enlarged bile duct mass and with enhanced estradiol serum levels. Cholangiocyte proliferation, during BDL, is impaired by estrogen ...

Primary biliarycirrhosis (PBC) is a progressive disease of the liver caused by a buildup of bile within the liver (cholestasis) that results in damage to the small bile ducts that drain bile from the liver. Over time, this pressure build-up destroys the bile ducts leading to liver cell damage. As the disease progresses and enough liver cells die, cirrhosis and liver failure occur.. Bile is manufactured in the liver and then transported through the bile ducts to the gallbladder and intestine where it helps digest fats and fat soluble vitamins (A,D,E,K). When bile cannot be drained from the liver, it causes inflammation that leads to cell death. Scar tissue gradually replaces the areas of damaged liver and then the body cannot perform necessary functions.. ...

Brachytherapy is done by an interventional radiologist and a radiation oncologist. The oncologist inserts radiation seeds attached to a wire into the bile duct. The seeds are placed as close as possible to the tumor or into the tumor itself. This is so that fewer normal cells are exposed to radiation. A small tube called a percutaneous transhepatic bile duct stent is put in the bile duct through your skin. The doctor carefully inserts the wire through your skin. Its guided down the stent to the area where the cancer is located. The doctor uses X-rays to guide the placement. The wire that extends outside your body is secured to your skin. After a period of time, the doctor carefully removes it using X-rays again as a guide. You will need to stay in the hospital while the radioactive seeds and wire are in place. ...

The only function of these stents is to promote biliary drainage; they have no antitumor effect. Methods: A metallic stent was developed that is covered with a paclitaxel-incorporated membrane. The metallic stents were coated with one of 3 concentrations of paclitaxel (0, 10, and 20 % wt/v) and polyurethane. A stent with each concentration was surgically inserted in the bile duct of two pigs. Four weeks after insertion, the segment of bile duct containing the stent was examined histologically.

Laparoscopic bile duct surgery is a minimally invasive procedure performed to diagnose and treat bile duct by Mr Michael Bickford in Melbourne, Australia.
There are two different ways to connect the bile duct to the intestine, depending on the liver disease of the patient. The first way is connecting the patients own bile duct to the donor bile duct. If this is done, a small tube called a T-tube, is placed between the bile duct connections. The tube will then exit through the skin but is easily concealed by clothing. This allows the team to monitor the amount and consistency of bile being made by the liver. This tube is tied off within the first week and removed six months after transplantation. The second way to connect the bile duct to the intestine is used if a patients own bile duct is diseased. In this situation, the new bile duct will be connected with the patients intestine. A small tube called a stent, is placed at the connection site. It later falls out of the duct on its own and is passed in the stool sometime after the operation ...

Cholangiocarcinoma (CCA) is a fatal cancer of the bile duct epithelial cell lining. The misdiagnosis of CCA and other biliary diseases may occur due to the similarity of clinical manifestations and blood tests resulting in inappropriate or delayed treatment. Thus, an accurate and less-invasive method for differentiating CCA from other biliary diseases is inevitable. We quantified methylation of OPCML, HOXA9, and HOXD9 in serum cell-free DNA (cfDNA) of CCA patients and other biliary diseases using methylation-sensitive high-resolution melting (MS-HRM). Their potency as differential biomarkers between CCA and other biliary diseases was also evaluated by using receiver operating characteristic (ROC) curves. The significant difference of methylation levels of OPCML and HOXD9 was observed in serum cfDNA of CCA compared to other biliary diseases. Assessment of serum cfDNA methylation of OPCML and HOXD9 as differential biomarkers of CCA and other biliary diseases showed the area under curve (AUC) of 0.850 (0

Jan, Im so sorry to hear this! Yes I do have a bile duct stent. First they tried and internal rerouting but the tumor was in the way, so the next step was a external biliary bag fed by a tube coming out the side of the liver. Its on my right side, towards the upper half of the rib cage. The bag itself is no problem, maybe 6 x 8 at most, and its lashed to my leg with a velcro strap. Very easy to clean, just wipe with alcohol then turn the knob and let it drain in the toilet. Recovery from the surgery has been pretty rough, though. IDK if thats from how compromised my system already was, or if its because my liver didnt like having a stent punched in it. Probably some of both; but Ive been exhausted beyond belief ever since I got home (2 weeks now). Praying and resting are my major activities. Hugs and prayers as you begin addressing this issue. ...
Pancreatic cancer patients often experience a number of disease-related complications, either at presentation or as the cancer progresses. Bile duct obstruction can occur as the disease progresses and presents with jaundice, nausea, and vomiting with or without fever. An ERCP or MRCP is used to stent the bile duct and allow for bile drainage and resolution of symptoms. If internal stenting in not successful, percutaneous stents may be placed to resolve bile duct obstruction as well. If patients also present with fever, antibiotic management for cholangitis is indicated with broad-spectrum coverage of gram-negatives, coliforms, and anaerobes.1. GI obstruction can occur as well, presenting with severe nausea, vomiting, and abdominal pain. It is often managed with bowel rest and decompression. If obstruction continues, a gastrostomy or gastrojejunostomy tube can be placed for decompression. Pancreatic function may also be compromised either by the cancer itself or as a complication of surgical and ...

Whether or not cholangiocytes transform into mesenchymal cells via EMT is a matter of controversy. EMT describes epithelial cells that adopt structural and functional characteristics of mesenchymal cells: loss of polarity, changes in cell-cell contacts, spindle-like shape, functional mobility changes to surrounding stroma, and production of ECM.45 Cholangiocytes are believed to participate in the generation of liver fibrosis by undergoing EMT. Reactive cholangiocytes lose their epithelial characteristics such as E-cadherin, CK-7, or CK-19 and acquire a mesenchymal phenotype as manifested by the expression of fibroblast-specific markers such as the fibroblast specific protein-1 (FSP-1) or vimentin, the ability to migrate and to produce ECM components such as collagen, fibronectin, elastin, and tenascin. The accumulating evidence indicates that EMT probably has a critical role in the process of portal fibrosis during chronic liver diseases (Table 2).46,47 Evidence favoring EMT of BEC comes from ...

Most experts believe that PBC is an autoimmune condition. This means that something goes wrong with the immune system (the bodys natural defence against infection and illness) and it attacks healthy tissue instead of fighting off infection. In cases of PBC, the immune system sends specialised cells that usually kill bacteria and viruses to the bile ducts.. These cells damage the surface of the bile ducts, which gradually become scarred and disrupt the flow of bile out of the liver. This increases the amount of bile in the liver, which over time can cause it to also become extensively damaged and scarred (cirrhosis).. This damage can gradually cause the liver to lose its function. As the liver plays a vital role in filtering out impurities and toxins from your blood, loss of liver function is potentially fatal.. It is not known what causes the immune system to malfunction and attack the bile ducts.. ...

Bill had 7 great days in a row. His pain was minimal. It was wonderful to have our old life back. Even if it was just for a short time. Unfortunately, like usual for us the good is shortly followed by the bad. Bills pain gradually came back. This pass Sunday, he started to look a little jaundice. He was running no fever and felt OK and still had an appetite. In fact he gained 14 pounds in 2 weeks and he mentioned that his belly is getting big again. Yesterday, he went for routine blood work for his chemo treatment. We found out today the billirubin is elevated. Chemo was cancelled and replaced with a CT scan and ultra sound. With the billirubin high, there was concerned that either the stent in the bile duct was clogged again or the tumor in the bile duct has grown. The test showed that the cancer has grown in the liver. They can not tell if the stent is clogged or the tumor has grown in the bile duct. Bills abdomen in retaining fluid and needs to be drained (reason for the rapid weight gain ...

What options do we have remaining? Ahhh....this is the million dollar question at the moment. The way I see things, and believe me there are many others who are looking at our girl and seeing things differently, but in the end the opinion that matters most is what Drew and I decide is best for Lucy. Currently we have put all of our proverbial eggs in one basket yet again, that basket being the GI doc at Hopkins in Baltimore. We are waiting to hear back from him to find out what options he recommends for trying to alleviate the symptoms associated with Lucys cholestasis and reoccurring cholangitis. We heard back from the GI doctor at Jefferson last week, his recommendation was a maximally invasive surgery in which we would reconstruct Lucys bile duct by bringing up a portion of her small intestine and attaching it to her liver. This option would definitely get rid of her floppy bile duct, but replacing one failing organ with another failing organ will most likely create an entirely new set of ...

A bile duct is any of a number of long tube-like structures that carry bile, and is present in most vertebrates. Bile, required for the digestion of food, is secreted by the liver into passages that carry bile toward the hepatic duct, which joins with the cystic duct (carrying bile to and from the gallbladder) to form the common bile duct, which opens into the intestine. The biliary tree (see below) is the whole network of various sized ducts branching through the liver. The path is as follows: Bile canaliculi → Canals of Hering → interlobular bile ducts → intrahepatic bile ducts → left and right hepatic ducts merge to form → common hepatic duct exits liver and joins → cystic duct (from gall bladder) forming → common bile duct → joins with pancreatic duct → forming ampulla of Vater → enters duodenum The bile duct is green like the gallbladder, because of bile stains. Inflation of a balloon in the bile duct causes, through the vagus nerve, activation of the brain stem and the ...

PY - 1995/1/1. Y1 - 1995/1/1. N2 - Primitive biliary cells are known to migrate from the ductal plate into the mesenchyme during human intrahepatic bile duct development, and this migration process is essential for normal development of intrahepatic bile ducts. However, its molecular mechanism is unknown. Matrix proteinases play an important role in cell migration during cancer invasion and organ development. In this study, we therefore investigated in situ expression of matrix metalloproteinases (MMP) and tissue inhibitors of MMP (TIMP) during human intrahepatic bile duct development, using 32 human fetal livers. We also examined in situ expression of trypsinogen/trypsin, chymotrypsinogen/chymotrypsin, and cathepsin B, which are matrix proteinases and activators of MMP. MMP-1 expression was noted in ...

Cytokine-responsive gene-2 (Crg-2), the murine ortholog of IP-10, was induced following CCl4 treatment of the hepatocyte-like cell line AML-12. Crg-2 expression was noted in vivo in multiple models of hepatic and bile duct injury, including bile duct ligation and CCl4, D-galactosamine, and methylene dianiline toxic liver injuries. Induction of Crg-2 was also examined following two-thirds hepatectomy, a model that minimally injures the remaining ...
Recent studies disclosed that autophagy is induced during and facilitates the process of senescence. Given that biliary epithelial cells (BECs) in damaged small bile ducts in primary biliary cirrhosis (PBC) show senescent features, we examined an involvement of autophagy in the process of biliary ep …
Aquaporin-1 (AQP1) water channels are present in the apical and basolateral plasma membrane domains of bile duct epithelial cells, or cholangiocytes, and mediate the transport of water in these cells. We previously reported that secretin, a hormone known to stimulate ductal bile secretion, increases cholangiocyte osmotic water permeability and stimulates the redistribution of AQP1 from an intracellular vesicular pool to the cholangiocyte plasma membrane. Nevertheless, the target plasma membrane domain (i.e., basolateral or apical) for secretin-regulated trafficking of AQP1 in cholangiocytes is unknown, as is the functional significance of this process for the secretion of ductal bile. In this study, we used primarily an in vivo model (i.e., rats with cholangiocyte hyperplasia induced by bile duct ligation) to address these issues. AQP1 was quantitated by immunoblotting in apical and basolateral plasma membranes prepared from cholangiocytes isolated from rats 20 min after intravenous infusion of secretin

TY - JOUR. T1 - Characterization of apical and basolateral plasma membrane domains derived from cultured rat cholangiocytes. AU - Tietz, Pamela. AU - Levine, Susan. AU - Holman, Ralph. AU - Fretham, Chris. AU - La Russo, Nicholas F. PY - 1997/12/15. Y1 - 1997/12/15. N2 - Cholangiocytes, the epithelial cells that line intrahepatic bile ducts, are composed of plasma membranes with discrete apical (lumenal) and basolateral domains that contain different channels, transporters, and receptors. In recent work, we developed a long-term, primary culture system of normal rat cholangiocytes (NRC). Our aims here were to prepare and characterize apical and basolateral plasma membrane vesicles from NRC. Using serial isopycnic centrifugation on sucrose gradients, we generated separate apical and basolateral plasma membrane vesicles. We characterized these vesicles by transmission electron microscopy, specific marker enzyme assays, and immunoblotting; we also determined the percentage of sealed vesicles and ...
Jaundice. This is the yellowing of the whites of the eyes and skin. Its caused by a buildup of bilirubin in the blood. Bilirubin is a yellow-brown substance in bile. The liver makes bile. Bile travels from the liver through the bile ducts the intestine. Bile digests or breaks down fats from food in the intestine. If the bile ducts are blocked by a tumor or scarring, bile backs up. Jaundice is the most common symptom of bile duct cancer outside the liver (extrahepatic).. ...
Primary Biliary Cirrhosis (PBC) is a chronic liver disease that is characterized by inflammation and progressive destruction of the bile ducts. PBC is usually diagnosed in patients between the ages of 35 to 60 years. About 90 to 95 percent of patients are women. Liver inflammation over a long period of time may cause scarring which leads to cirrhosis. The cause of PBC is unknown, but it is most likely an autoimmune disease. An autoimmune disease is a process where the immune system attacks a specific tissue in the body. In PBC, it is thought that the immune system attacks and destroys small bile duct cells in the liver. It is not uncommon for patients with PBC to have other associated autoimmune diseases including pernicious anemia, scleroderma, or thyroid disorders. In addition, there are environmental factors such as infections, which may trigger the disease. Due to widespread laboratory screening, the number of patients being diagnosed early in the asymptomatic stage has risen dramatically ...
Cell lines and tissue specimens. TFK-1 and HuH28 (two human ICC cell lines) were obtained from Cell Resource Center for Biomedical Research, Institute of Development, Aging and Cancer, Tohoku University; OZ (another ICC line) was from Japan Health Science Foundation; and ETK-1, RBE, and SSP-25 (three ICC lines) were from RIKEN Bioresource Center. HCT116 colon cancer cells were gifts from Dr. B. Vogelstein. All lines were grown in monolayers in appropriate media: RPMI 1640 (Sigma) for ETK-1, RBE, SSP-25, and TFK-1; MEM (Sigma) for HuH28; Williams medium E (Sigma) for OZ; and McCoys 5a for HCT116, supplemented with 10% fetal bovine serum and 1% antibiotic/antimycotic solution (Sigma). Cells were maintained at 37°C in an atmosphere of humidified air containing 5% CO2. We obtained ICC tissues from 21 patients who underwent hepatectomy and normal intrahepatic bile duct epithelia from 10 patients who underwent hepatectomy due to metastatic liver tumors in Kyoto University Hospital with informed ...
Surgical models of acute liver injury and repair, such as partial hepatectomy or common bile duct ligation (cBDL), have been used for decades in rodents to study liver regeneration and pathobiology 1, 2.In cBDL, the common bile duct (which drains all bile produced in the liver) is ligated, resulting in obstructive cholestasis, inflammation, and fibrosis in the first 2-3 weeks following surgery . ...
As part of medical care subjects will be undergoing an endoscopic procedure (ERCP) in order to evaluate and stent a bile duct blockage. During the ECRP and just prior to the stent placement subjects will undergo the placement of a radiofrequency ablation catheter into the bile duct blockage. Heat will be applied to the bile duct in order to open the blockage and prevent the re-growth of tissue into the stent; after the radiofrequency ablation, stent will be placed. Three days after the procedure subjects will receive a phone call from the research coordinator to check any adverse or unwanted effects of the treatment. The study procedure (radiofrequency ablation) takes place over 10 minutes during ERCP. The subjects will undergo routine follow up for their medical problems. No follow up visits are required as part of the study ...
Aims: Primary biliary cirrhosis (PBC) is an autoimmune liver disease targeting the intrahepatic small bile ducts showing chronic non-suppurative destructive cholangitis (CNSDC). Recent studies suggest that naturally-occurring CD4+CD25high regulatory T cells (Tregs) expressing Forkhead box P3 (Foxp3) play an active role in immunological self-tolerance. In this study, we investigated whether Foxp3+Tregs are involved in the pathogenesis of PBC or not. Methods: Foxp3+Tregs was detected immunohistochemically in livers from the patients with PBC (n=27), chronic viral hepatitis (CVH) (n=15), and normal livers (n=10). The distribution of Tregs in portal tracts was semi-quantitatively evaluated in each groups. The level of Foxp3, IL-10, TGFβ, IFNγ and TNFα mRNA was evaluated in PBC (n=15) and control livers (n=21) using semi-quantitative RT-PCR. Results: In PBC and CVH livers, the amounts of infiltrating Foxp3+Tregs in portal tracts were in parallel with the degree of portal inflammation irrespective ...

Biliary-enteric anastomosis (BEA) is a common surgical procedure performed for the management of biliary obstruction or leakage that results from a variety of benign and malignant diseases. Complications following BEA are not rare. We aimed to determine the incidence and the factors associated with early complications occurring after BEA for benign diseases. We reviewed the medical records of all patients who underwent BEA for benign diseases at our institution between January 1988 and December 2009. The primary outcome was early post operative complication. Logistic regression analysis was done to identify factors predicting the occurrence of complications. Records of 79 patients were reviewed. There were 34 (43%) males and 45 (57% females). Majority (53%) had choledocholithiasis with impacted stone or distal stricture, followed by traumatic injury to the biliary system (33%). Thirty-four patients (43%) underwent a hepaticojejunostomy, 19 patients (24%) underwent a choledochojejunostomy, and

PBC has an immunological basis, and is classified as an autoimmune disorder.[12] It results from a slow, progressive destruction of the small bile ducts of the liver, with the intralobular ducts and the Canals of Hering (intrahepatic ductules) being affected early in the disease.[13] This progresses to the development of fibrosis, cholestasis and, in some people, cirrhosis.[2]. Most people with PBC (,90 percent) have anti-mitochondrial antibodies (AMAs) against pyruvate dehydrogenase complex (PDC-E2), an enzyme complex that is found in the mitochondria.[1] People who are negative for AMAs are usually found to be positive when more sensitive methods of detection are used.[14]. People with PBC may also have been diagnosed with another autoimmune disease, such as a rheumatological, endocrinological, gastrointestinal, pulmonary, or dermatological condition, suggesting shared genetic and immune abnormalities.[11] Common associations include Sjögrens syndrome, systemic sclerosis, rheumatoid ...
Primary biliary cholangitis is a rare disease that slowly destroys the small bile ducts of the liver, reducing the organs function over time. Formerly known as primary biliary cirrhosis, it mostly affects women and usually appears between ages 30 and 60.

Identifying the factors that contribute to organ progenitor cell maintenance and differentiation is of crucial importance to developmental and disease-related research. In their study of liver development, Suzuki et al. have now identified such a factor, the transcription factor Tbx3, and investigated its functions in hepatoblast proliferation and cell fate determination (see p. 1589). The authors discovered that Tbx3 is expressed in mouse hepatoblasts (which differentiate into hepatocytes and bile duct epithelial cells) using a fluorescence flow cytometry-based technique to identify different embryonic liver cell populations, which they assayed for the expression of numerous T-box genes. Tbx3 is a known transcriptional repressor of p19ARF, so the researchers next investigated the expression of p19ARF in normal and Tbx3-null hepatoblasts and found that Tbx3 loss results in a p19ARF-induced growth arrest, which pushes hepatoblasts towards a bile duct epithelial fate. These findings thus show that ...
As a general surgeon with 12 years of experience: I have never had a cystic duct leak or a major bile duct injury in my practice. I have had some duct-of-Luschka leaks, however; roughly the 1/200 rate quoted in the literature. In recent years, my bile leak rate is down. I think it is because of my increased use of blunt dissection to free the gallbladder from the liver bed, and decreased use of cautery (especially when I cant visualize a nice areolar plane.) Sometimes I essentially peel the gallbladder off of the liver. Staying out of the liver (and also staying out of the gallbladder), is a big deal in my opinion. I think it reduces the rate of bile leaks and of major bleeds from the liver bed ...

N2 - ATP in bile is a potent secretogogue, stimulating cholangiocyte Cl- and fluid secretion via binding to membrane P2 receptors, though the physiological stimuli involved in biliary ATP release are unknown. The goal of the present studies was to determine the potential role of fluid flow in biliary ATP release and secretion. In both human Mz-Cha-1 biliary cells and normal rat cholangiocyte monolayers, exposure to flow increased relative ATP release which was proportional to the shear stress. In parallel studies, shear was associated with an increase in [Ca2+]i and membrane Cl- permeability, which were both dependent on ...
The biliary tree is an essential component of transplantable human liver tissue. Despite recent advances in liver tissue engineering, attempts at re-creating the intrahepatic biliary tree have not progressed significantly. The finer branches of the biliary tree are structurally and functionally complex and heterogeneous and require harnessing innate developmental processes for their regrowth. Here we demonstrate the ability of decellularized liver extracellular matrix (dECM) hydrogels to induce the in vitro formation of complex biliary networks using encapsulated immortalized mouse small biliary epithelial cells (cholangiocytes). This phenomenon is not observed using immortalized mouse large cholangiocytes, or with purified collagen 1 gels or Matrigel. We also show phenotypic stability via immunostaining for specific cholangiocyte markers. Moreover, tight junction formation and maturation was observed to occur between cholangiocytes, exhibiting polarization and transporter activity. To better define the
ConclusionEctopic biliary drainage into the stomach is extremely rare, but its recognition may help identify the cause of certain clinical conditions and prevent bile duct injury during surgery if required....
Ductular reaction (DR) in bile duct ligated rats generally appears from 2nd day after biliary obstruction (BO). However, we show that increased amount of ductular profiles is evident already in 6 hours after BDL. The study aims to explain the origin of such an early DR in response to BO. Male Lewis rats were subjected to common bile duct ligation (CBDL) for 3, 6, 12 and 24 hours and sham operation. Liver samples were studied histologically, immunohistochemically (Ki67, pan-Cytokeratin /AE1 + AE3/ and OV-6) and by immunoblotting analyses. It appeared that number of ductular profiles increase in timerelated manner after BO. These ductular profiles are formed by biliary epitheliocyte-like cells; No mitotic activity was revealed. Part of hepatocytes reveals pan-Cytokeratin positivity on 12 and 24 hours after BO. Total cytokeratins content at 24 hours after CBDL was 37% higher in comparison with control data. The significant increase was observed for the cytokeratins with molecular weights: 61, 56 ...
Cholestasis is a term used to denote a condition in which obstruction of the bile duct prevents the normal flow of bile from the liver to the duodenum (a part of small intestine). Cholestasis can occur due to number of underlying diseases, including diseases of the liver, gallbladder, or pancreas.
AIM To investigate the role of hepatic peroxisome proliferator-activated receptor-γ (PPAR-γ) in increased susceptibility to endotoxin-induced toxicity in rats with bile duct ligation during endotoxemia. METHODS Male Sprague-Dawley rats were subjected to bile duct ligation (BDL). Sham-operated animals served as controls. DNA binding were determined by polymerase chain reaction, Western blotting analysis, and electrophoretic mobility shift assay, respectively. BDL and sham-operated rats received a non-lethal dose of intraperitoneal lipopolysaccharide (LPS) injection (3 mg/kg, i.p.). Additionally, the potential beneficial effects of the PPAR-γ agonist rosiglitazone were determined in BDL and sham-operated rats treated with a non-lethal dose of LPS. Survival was assessed in BDL rats treated with a non-lethal dose of LPS and in sham-operated rats treated at a lethal dose of LPS (6 mg/kg, i.p.). RESULTS PPAR-γ activity in rats undergoing BDL was significantly lower than in the sham-controls. Hepatic
Among infants who underwent surgery to repair bile ducts that do not drain properly (biliary atresia), the administration of high-dose steroid therapy following surgery did not significantly improve bile drainage after six months, although a small clinical benefit could not be excluded, according to a study in the May 7 issue of JAMA, a theme issue on child health. This issue is being released early to coincide with the Pediatric Academic Societies Annual Meeting.

The distal part of the hepatic diverticulum transforms into a complex of branching cords of cells (trabeculae) separated by venous channels (sinusoids), which together make up the liver. The liver lies in the most cranial part of the abdominal cavity and remains separated from the heart by the septum transversum. The proximal part of the hepatic diverticulum becomes the bile duct that empties into the fore- and midgut junction. The gall bladder forms as a diverticulum of the bile duct on the caudal surface of the liver. The bile duct then continues to the liver as the hepatic duct. The ventral pancreas is represented as a branching duct that moves first to the right side of the duodenum then to a dorsal position. It grows into the dorsal mesoduodenum and lies to the right of the portal vein. The ventral pancreatic duct joins the bile duct near the duodenum ...

The majority of cells in the liver are hepatocytes, which constitute two-thirds of the mass of the liver. The remaining cell types are Kupffer cells (members of the reticuloendothelial system), stellate (Ito or fat-storing) cells, endothelial cells and blood vessels, bile ductular cells, and supporting structures. Viewed by light microscopy, the liver appears to be organized in lobules, with portal areas at the periphery and central veins in the center of each lobule. However, from a functional point of view, the liver is organized into acini, with both hepatic arterial and portal venous blood entering the acinus from the portal areas (zone 1) and then flowing through the sinusoids to the terminal hepatic veins (zone 3); the intervening hepatocytes constituting zone 2. The advantage of viewing the acinus as the physiologic unit of the liver is that it helps to explain the morphologic patterns and zonality of many vascular and biliary diseases not explained by the lobular arrangement. ...

In advanced stages of liver disease, doctors have found that a persons liver is choked with bile duct cells. This is thought to be one of the main causes of the health problems that accompany the condition. On the other hand, hepatocytes play an important role in detoxifying the liver. They are known to be very scarce in a person with liver disease ...
Rats were fed N-nitrosomorpholine (NNM) at low or high concentrations for 6 or 12 weeks. Both NNM schedules resulted in development of hepatomas. During the early stages of hepatoma induction, liver histotoxic patterns depended only on the dose of carcinogen employed. Necrosis of hepatocytes and proliferation of small, oval-shaped cells occurred when high doses of NNM were applied. Parallel to the proliferation of oval-shaped cells, resurgence of alpha1-fetoprotein (AFP) in rat sera was observed and production of this protein was confined to the oval-shaped cells as shown by immunoperoxidase staining. During proliferation of bile duct epithelium, induced by galactosamine injections, those cells could also stain for AFP, and proliferation of oval-shaped cells concomitant with intracellular AFP staining resulted from restitution of heavily damaged liver. At the stage of malignant conversion, distinct AFP-staining nodules were localized which consisted of neoplastic hepatocytes ...

CoCC shows a variable histological morphology depending on the extent of the associated ICC/HCC components. Such an inherent histological heterogeneity potentially complicates the pathologic diagnosis of CoCC. Komuta et al. proposed that CoCC is defined as when the proportion of CoCC accounts for more than 90% of the entire tumor [8]. According to this strict definition, CoCC with a significant proportion of ICC or HCC components may be considered to be an ordinary ICC or HCC, respectively [4]. The authors also reported immunohistochemical findings of a positive EMA at the apical membrane [6, 8, 9], positive NCAM (a marker of hepatic progenitor cells), and negative S100P (a marker of intrahepatic large bile ducts) [8]. As described, we made an incorrect initial diagnosis of ordinary ICC in the present patient, primarily because a lack of knowledge of CoCC led us not to consider the possibility of CoCC. There may be a concern that pathological diagnosis of the recurrent lesions treated with RFA ...
