    To determine if CCK FC can aid in the diagnosis (Dx.) of ABD, the authors retrospectively analyzed the max. gallbladder (GB) ejection fraction response (EFR) to CCK in 240 patients (pts.) with persistent symptoms of biliary colic, a normal GB Ultrasound exam and/or OCG. Each pt. (NPO after 12 A.M.) received 5 mCi of technetium (Tc)-99 Hepatolite. After max GB filling, .02 ..mu..g/kg CCK was administered (1-3 minutes) I.V. Background corrected GB EFs were determined q.5 min x4 by ratioing the pre-CCK GB cts. minus post-CCK GB cts. to pre-CCK GB cts. In 131/240 pts. the max. GBEFR was <35%; 76 had a cholecystectomy (Cx.), 2 an exploratory lap., 53 medical Rx. Of the 76 post-Cx. pts., 74 had chronic cholecystitis (CC) (67 acalculous, 7 calculous), 2 were normal. Exploratory lap. pts, had no GB disease. Clinically 69/70 (4 no followup, 1 no change) post-op CC pts. are improved. One normal GB pt. has persistent pain, the other a Sphincter of Oddi dyskinesia. Of the 53 medical Rx. pts. 23 are lost to followup, and 2 died. Twenty-four are clinically felt to have ABD, 4 are not. In 109/240 pts. the max GBEFR was >35%. Eleven underwent surgery, 98 medical Rx. 4/11 Cx. apts had CAC, 7 were normal. Of the 98 medical Rx. pts. 21 lack followup, 71 are clinically felt not to have ABD; 6 are felt to have ABD. CCK FC appears to be a useful test for the detection of ABD. Its predictive value (GBEF <35%) in Cx. pts. is 97%; in all pts. (assuming medical Rx. correct), 94% (sensitivity - 91%, specificity - 93%).

  2. Fatty meal ultrasonography in chronic acalculous cholecystitis

    Chronic acalculous cholecystits typically presents with biliary symptoms, normal blood tests and unremarkable ultrasound, computerized tomography and magnetic resonance cholangiopancreatography. However, cholescintigraphy may show reduced gallbladder ejection fraction (GBEF). There are no reports on using ultrasound to measure GBEF in adults. Twenty-eight patients with the above presentation underwent ultrasound before and after ingestion of a standardized fatty meal. Consequently, GBEF was calculated. Seven patients had reduced GBEFs (<38%). Two of these patients underwent cholecystectomy and both were found to have chronic gallbladder inflammation. Three patients with normal GBEFs underwent cholecystectomy and were also found to have chronic gallbladder inflammation. There may be a role for fatty meal ultrasonography in the diagnosis of chronic acalculous cholecystitis, but it should be used more widely in this patient cohort for its role to be established. It ideally needs to performed alongside cholescintigraphy for the comparison of accuracy. PMID:25409675

    Herein we describe two cases of Cystoisospora belli infection of the gallbladder in patients with chronic abdominal pain and review the published literature to date. C. belli is an intracellular protozoan parasite that typically infects the small bowel of immunocompromised hosts. Little is known of the significance of C. belli infection of the gallbladder at this point as only four cases have been reported as yet, only one of which occurred in an immunocompetent patient. It is often treatable with antibiotics, and the patient's immune status, including HIV testing, should be investigated. Neither of the patients at our institution was found to be immunocompromised, and HIV-1/2 antibody testing was non-reactive in both.

    This paper reviews the progress made in understanding the mechanical behaviour of the biliary system. Gallstones and diseases of the biliary tract affect more than 10% of the adult population. The complications of gallstones, i.e. acute pancreatitis and obstructive jandice, can be lethal, and patients with acalculous gallbladder pain often pose diagnostic difficulties and undergo repeated ultrasound scans and oral cholecystograms. Moreover, surgery to remove the gallbladder in these patients, in an attempt to relieve the symptoms, gives variable results. Extensive research has been carried out to understand the physiological and pathological functions of the biliary system, but the mechanism of the pathogenesis of gallstones and pain production still remain poorly understood. It is believed that the mechanical factors play an essential role in the mechanisms of the gallstone formation and biliary diseases. However, despite the extensive literature in clinical studies, only limited work has been carried out to study the biliary system from the mechanical point of view. In this paper, we discuss the state of art knowledge of the fluid dynamics of bile flow in the biliary tract, the solid mechanics of the gallbladder and bile ducts, recent mathematical and numerical modelling of the system, and finally the future challenges in the area.

    During an 11 year period, 47 patients with acute acalculous cholecystitis were operated on. Two to one male/female ratio was observed with a mean age of 55 age of 55 years. No one had a past history of biliary tract pathology but 70 per cent of the patients had risk factors, mainly diabetes mellitus, cardiovascular and collagenous diseases, some different of those reported in the world literature (sepsis, trauma, non biliary tract surgery, etc.). The ultrasound was the best diagnostic tool. Open cholecystectomy was performed in all patients and some sort of local complication was found in 85 per cent of patients (empyema, gangrene or perforation) in spite of the surgical procedure was done on emergency or early elective basis, a 31 per cent operative mortality rate was found and a 10.6% Operative mortality rates was observed. The bacterial cultures showed gram negative and anaerobic flora. This report shows that an early diagnosis and surgical treatment keeps a low morbidity and mortality rates but the gallbladder late complications have a high rates.

    Background and Purpose. Percutaneous transhepatic biliary drainage remains a painful procedure in many cases despite the routine use of large amounts of intravenous sedation. We present a feasibility study of thoracic paravertebral blocks in an effort to reduce pain during and following the procedure and reduce requirements for intravenous sedation. Methods. Ten consecutive patients undergoing biliary drainage procedures received fluoroscopically guided paravertebral blocks and then had supplemental intravenous sedation as required to maintain patient comfort. Levels T8-T9 and T9-T10 on the right were targeted with 10-20 ml of 0.5% bupivacaine. Sedation requirements and pain levels were recorded. Results. Ten biliary drainage procedures in 8 patients were performed for malignancy in 8 cases and for stones in 2. The mean midazolam use was 1.13 mg IV, and the mean fentanyl requirement was 60.0 {mu}g IV in the block patients. Two episodes of hypotension, which responded promptly to volume replacement, may have been related to the block. No serious complications were encountered. The mean pain score when traversing the chest wall, liver capsule, and upon entering the bile ducts was 0.1 on a scale of 0 to 10, with 1 patient reporting a pain level of 1 and 9 reporting 0. The mean peak pain score, encountered when manipulating at the common bile duct level or when addressing stones there, was 5.4 and ranged from 0 to 10. Conclusions. Thoracic paravertebral block with intravenous sedation supplementation appears to be a feasible method of pain control during biliary interventions.

    Intravenous calcium infusions produced subjective relief of bone pain in 14 patients with primary biliary cirrhosis. The bone pain had developed despite long-term parenteral vitamin D therapy. The pain returned after two to three months, but a subsequent course of infusions again brought relief. Before treatment satisfactory iliac crest bone biopsies were obtained in 11 of the patients and were normal in seven; two patients had biopsies indicating osteomalacia and two osteoporosis. After treatment a repeat biopsy in one of the patients with osteomalacia showed marked reduction in osteoid. The infusion treatment produced no change in plasma calcium concentration, serum phosphate, or serum alkaline phosphatase. Absorption of oral calcium was also unchanged. PMID:4279816

    AIM: To characterize functional biliary pain and other gastrointestinal (GI) symptoms in postcholecystectomy syndrome (PCS) patients with and without sphincter of Oddi dysfunction (SOD) proved by endoscopic sphincter of Oddi manometry (ESOM), and to assess the post-endoscopic sphincterotomy (EST) outcome. METHODS: We prospectively investigated 85 cholecystectomized patients referred for ERCP because of PCS and suspected SOD. On admission, all patients completed our questionnaire. Physical examination, laboratory tests, abdominal ultrasound, quantitative hepatobiliary scintigraphy (QHBS), and ERCP were performed in all patients. Based on clinical and ERCP findings 15 patients had unexpected bile duct stone disease and 15 patients had SOD biliary typeI. ESOM demonstrated an elevated basal pressure in 25 patients with SOD biliary-type III. In the remaining 30 cholecystectomized patients without SOD, the liver function tests, ERCP, QHBS and ESOM were all normal. As a control group, 30 ‘asymptomatic’ cholecystectomized volunteers (attended to our hospital for general cardiovascular screening) completed our questionnaire, which is consisted of 50 separate questions on GI symptoms and abdominal pain characteristics. Severity of the abdominal pain (frequency and intensity) was assessed with a visual analogue scale (VAS). In 40 of 80 patients having definite SOD (i.e. patients with SOD biliary typeIand those with elevated SO basal pressure on ESOM), an EST was performed just after ERCP. In these patients repeated questionnaires were filled at each follow-up visit (at 3 and 6 mo) and a second look QHBS was performed 3 mo after the EST to assess the functional response to EST. RESULTS: The analysis of characteristics of the abdominal pain demonstrated that patients with common bile duct stone and definite SOD had a significantly higher score of symptomatic agreement with previously determined biliary-like pain features than patient groups of PCS without SOD and controls

    Abstract Enhanced computed tomography (CT) is widely used for evaluating acute biliary pain in the emergency department (ED). However, concern about radiation exposure from CT has also increased. We investigated the usefulness of pre-contrast CT for differential diagnosis in middle-aged subjects with suspected biliary pain. A total of 183 subjects, who visited the ED for suspected biliary pain from January 2011 to December 2012, were included. Retrospectively, pre-contrast phase and multiphase CT findings were reviewed and the detection rate of findings suggesting disease requiring significant treatment by noncontrast CT (NCCT) was compared with cases detected by multiphase CT. Approximately 70% of total subjects had a significant condition, including 1 case of gallbladder cancer and 126 (68.8%) cases requiring intervention (122 biliary stone-related diseases, 3 liver abscesses, and 1 liver hemangioma). The rate of overlooking malignancy without contrast enhancement was calculated to be 0% to 1.5%. Biliary stones and liver space-occupying lesions were found equally on NCCT and multiphase CT. Calculated probable rates of overlooking acute cholecystitis and biliary obstruction were maximally 6.8% and 4.2% respectively. Incidental significant finding unrelated with pain consisted of 1 case of adrenal incidentaloma, which was also observed in NCCT. NCCT might be sufficient to detect life-threatening or significant disease requiring early treatment in young adults with biliary pain. PMID:25700321

    Forty-one proved cases of acute acalculous cholecystitis imaged with technetium-99m iminodiacetic acid (IDA) cholescintigraphy were retrospectively analyzed. After the exclusion of one indeterminate scan (showing poor initial hepatic uptake and excretion), the study yielded a 92.5% (37 of 40) sensitivity for the detection of cystic or common bile duct obstruction. Each of the three patients with false-negative scintigrams had other abnormal scintigraphic findings suggestive of biliary tract disease. Of the 20 patients (48.8%) with focal or diffuse gangrenous cholecystitis or perforation, seven (35%) exhibited either free peritoneal spill or increased pericholecystic activity to indicate the presence of advanced disease.

  11. Biliary Dyskinesia.

    PubMed

    Toouli, James

    Biliary dyskinesia is a motility disorder that affects the gallbladder and sphincter of Oddi. The motility disorder of the gallbladder is called gallbladder dyskinesia. Patients with this condition present with biliary-type pain, and investigations show no evidence of gallstones in the gallbladder. The diagnosis is made by performing a gallbladder ejection fraction, which is a radionuclide investigation. An abnormal gallbladder ejection fraction has a value less than 40%. Patients with an abnormal gallbladder ejection fraction should undergo cholecystectomy. This procedure has been shown to be effective in curing the symptoms in over 90% of patients. Motility disorder of the sphincter of Oddi is called sphincter of Oddi dysfunction. This disorder is categorized as two distinct types--biliary sphincter of Oddi dysfunction and pancreatic sphincter of Oddi dysfunction. Typically, patients with biliary sphincter of Oddi dysfunction present with biliary-type pain on average 4 to 5 years after having undergone cholecystectomy. Sphincter of Oddi manometry is essential in making a diagnosis of abnormal motility of the sphincter. On manometry, diagnosis of a sphincter of Oddi stenosis should lead to division of the sphincter. Sphincterotomy results in long-term relief of symptoms in more than 80% of patients. Pancreatic sphincter of Oddi dysfunction clinically presents with recurrent episodes of pancreatitis of unknown cause. Having ruled out all of the common causes of pancreatitis, sphincter of Oddi manometry of the pancreatic duct sphincter should be performed. When manometric stenosis is diagnosed, these patients should undergo division of both the biliary and pancreatic duct sphincter. This treatment results in relief of symptoms in more than 80% of patients.

    Acute acalculous cholecystitis (ACC) is most frequently reported in critically ill patients following sepsis, extensive injury or surgery. It is rather uncommon as a chemotherapy-induced complication, which is usually life-threatening in neutropenic patients subjected to myelosuppressive therapy. A 23-year-old patient with acute lymphoblastic leukemia was subjected to myelosuppressive chemotherapy (cyclophosphamide, cytarabine, pegaspargase). After the first chemotherapy cycle the patient was neutropenic and feverish; she presented with vomiting and pain in the right epigastrium. Ultrasound demonstrated an acalculous gallbladder with wall thickening up to 14 mm. The ACC was diagnosed. Medical therapy included a broad spectrum antibiotic regimen and granulocyte-colony stimulating factors. On the second day after ACC diagnosis the patient's general condition worsened. Laparoscopic cholecystectomy was performed. The resected gallbladder showed no signs of bacterial or leukemic infiltrates. The postoperative course was uneventful. In the management of neutropenic patients with ACC surgical treatment is as important as pharmacological therapy. PMID:25337176

    Choledocholithiasis (CDL) usually presents with biliary pain. Painless CDL is also known to occur, especially in the elderly. The purpose of this study is to determine whether the mode of presentation (painful vs. painless) influences the clinical course and outcomes of CDL in African American and Hispanic patients. Ten years of admission and discharge records (January 1998-December 2007) were reviewed retrospectively, yielding 527 community hospital patients, aged 23-97 years, with the final diagnosis of CDL. Patients with painless presentation had higher odds of having comorbidities compared to patients presenting with pain. However, patients who presented with biliary pain were predominantly younger (mean age 34 years), and 59% were Hispanic females (p = 0.001). In our study painless CDL was associated with higher morbidity and mortality.

    Ceruletide is a decapeptide isolated from the skin of an Australian frog. Its chemical and biologic relationship to cholecystokinin and its potent relaxant effect on the sphincter of Oddi makes it useful in biliary colic. In this double-blind placebo-controlled experiment, 60 subjects with moderate to severe pain caused by biliary colic were injected with ceruletide, 1 ng/kg iv or with an equal volume of saline solution. Pain in the right hypochondrium, referred pain, and Murphy's sign were scored before and after treatment. Data indicate that ceruletide is effective in biliary colic.

    2007-08-01

    Gallbladder and biliary dyskinesia are conditions that are becoming increasingly recognized due to improved technology. They are motility disorders that affect the gallbladder and sphincter of Oddi (SO), respectively. Gallbladder dyskinesia presents with typical biliary pain in the absence of gallstones. Work-up includes laboratory tests and imaging to rule out gallstones. Further investigation leads to a functional radionuclide study to investigate gallbladder ejection fraction. An ejection fraction of less than 40% is considered abnormal, and patients should be referred for cholecystectomy. Symptom relief after the procedure has been seen in 94% to 98% of patients. The term sphincter of Oddi dysfunction (SOD) describes a collection of pain syndromes that are attributed to a motility disorder of the SO. SOD can be further subdivided into biliary and pancreatic SOD. Patients typically have had a prior cholecystectomy and present with episodic biliary pain. The initial work-up includes laboratory tests and imaging to rule out other structural causes of abdominal pain, such as retained gallstones. Imaging and laboratory studies further subdivide patients into types of SOD. SO manometry (SOM) is the gold standard for assessing biliary dyskinesia and can help stratify patients into one of two groups: SO stenosis versus SO dyskinesia. Those with stenosis (type I SOD) are the most likely to respond to treatment with endoscopic biliary sphincterotomy (EBS). As the vast majority of type I patients (>/= 90%) benefit from EBS, SOM is not necessary. Pancreatic SOD patients can be similarly divided into one of three groups. These patients present with recurrent bouts of abdominal pain and/or pancreatitis in the absence of gallstones or other structural abnormalities. Pancreatic sphincter manometry can help distinguish which patients would benefit from endoscopic pancreatic sphincterotomy. Recurrent stenosis of the opening after endoscopic treatment in these patients may

    Aim: This study is aimed to evaluate the role of cholescintigraphy in management of acute acalculous cholecystitis. Materials and Methods: A total of thirty two patients who had presented to the surgical out-patient department or referred from in-patient department or intensive care unit between February 2008 and February 2010 were studied. All patients with Ultrasonography abdomen findings of acalculous cholecystitis were included in the study and they underwent cholescintigraphy. Gall bladder ejection fraction (GBEF) was calculated 30 min after fatty meal. Patients who either had non-visualization of gall bladder or GBEF less than 40% were considered to have acalculous cholecystitis on cholescintigraphy. The patients were followed-up for a period of 3 months after the commencement of treatment. Results: Eleven patients had either non-visualization of gall bladder or GBEF < 40%. Of these, six patients underwent cholecystectomy and the rest were medically managed, as patients deferred surgery. 83.33% of post-cholecystectomy patients as against 40% of medically treated patients were symptom free. Twenty one patients had GBEF > 40%, 90.74% of these patients were symptom free at the end of 3 months, with medical management. Conclusion: Cholescintigraphy is an important adjunct in management of patients with acalculous cholecystitis by guiding the course of therapy-surgical management versus medical management.

    To evaluate the role of quantitative cholescintigraphy with fatty meal in the management of biliary dyskinesia and to describe the findings according to Sostre score (SS) criteria in patients with gallbladder (GB) in-situ and biliary pain. We performed a retrospective analysis of the hepatobiliary (HIDA) studies (n = 35) performed for evaluation of biliary dyskinesia either due to biliary pain, opioid induced sphincter of Oddi dysfunction (SOD), recurrent pancreatitis (RP) or post cholecystectomy syndrome (PCS). Gallbladder ejection fraction (GBEF) was calculated from the post fatty meal HIDA images (excluding PCS patients). Studies with GBEF ≤40 % and SS >4 were considered to have cholecystopathy and SOD respectively. Three of the 13 patients with PCS had SS of 6 each, suggestive of SOD. Delayed biliary visualization (>15 min) and activity in common bile duct 60 min > liver 15 min were the specific features in these cases. Opioid induced SOD patients had SS >4 with retrograde refilling of GB in one patient and normalization of the SS parameters after nifedipine challenge in the other patient. Patients with RP and biliary pain were stratified into four groups, normal (GBEF >40 % and SS ≤4), cholecystopathy (GBEF ≤40 % and SS ≤4), normal with SOD (GBEF >40 % and SS >4) and cholecystopathy with SOD (GBEF ≤40 % and SS >4). Four patients with intact GB had cholecystopathy with scintigraphic features of SOD. Quantitative cholescintigraphy with fatty meal and SS scoring identified biliary dyskinesia and SOD in patients with biliary pain, recurrent pancreatitis and post-cholecystectomy syndrome.

    Biliary ascariasis is a complication of intestinal ascariasis. This results in characteristic findings in the intravenous cholangiocholecystogram and in the sonogram. Characteristic signs of biliary ascariasis are, in the longitudinal section, the "strip sign", "spaghetti sign", "inner tube sign", and in transverse section "a bull's eye in the triple O". The helminth can travel from out of the biliary duct system back into the intestines, so that control examinations can even be negative.

    2012-01-01

    Background/Aim: The objective of this study was to assess the value of hepatobiliary scintigraphy (HS) for the diagnosis of right upper quadrant (RUQ) abdominal pain in patients with normal hepatobiliary ultrasound (HU). This is an observational study with a retrospective analysis of data from March 2008 to August 2010. Materials and Methods: We reviewed the HS results of 30 patients, aged 29–69 years (average 45.8 years); 12 male and 18 female patients. Patient selection to perform the HS was RUQ abdominal pain, suspected hepatobiliary disorder, and negative HU. All patients had gone through the standard procedure of HS. Results: Based on predefined interpretation criteria, HS results were divided into 2 patterns: Normal (n=8, 25.8%) and abnormal (n=22, 73%): 18 patients (81.8%) having early gallbladder (GB) and common bile duct visualization, and delayed transit to small bowel (SB), which can be seen only after a fatty meal with normal or abnormal GB ejection fraction (GBEF) pattern characteristic of Oddi's sphincter dyskinesia. The remaining 4 patients (8.18%) had acalculous cholycystitis pattern: Delayed GB visualization with activity appearing in SB before GB. Conclusion: HS with fatty meal stimulation and GBEF estimation seems to be a reliable test, which may reveal a biliary cause in more than 70% of patients with RUQ abdominal pain and normal HU. Normal results exclude functional biliary cause. The decision for invasive or noninvasive therapeutic approach may depend on the results of HS. PMID:22824767

    2013-01-01

    Various biliary pathologic conditions can lead to acute abdominal pain. Specific diagnosis is not always possible clinically because many biliary diseases have overlapping signs and symptoms. Imaging can help narrow the differential diagnosis and lead to a specific diagnosis. Although ultrasonography (US) is the most useful imaging modality for initial evaluation of the biliary system, multidetector computed tomography (CT) is helpful when US findings are equivocal or when biliary disease is suspected. Diagnostic accuracy can be increased by optimizing the CT protocol and using multiplanar reformations to localize biliary obstruction. CT can be used to diagnose and stage acute cholecystitis, including complications such as emphysematous, gangrenous, and hemorrhagic cholecystitis; gallbladder perforation; gallstone pancreatitis; gallstone ileus; and Mirizzi syndrome. CT also can be used to evaluate acute biliary diseases such as biliary stone disease, benign and malignant biliary obstruction, acute cholangitis, pyogenic hepatic abscess, hemobilia, and biliary necrosis and iatrogenic complications such as biliary leaks and malfunctioning biliary drains and stents. Treatment includes radiologic, endoscopic, or surgical intervention. Familiarity with CT imaging appearances of emergent biliary pathologic conditions is important for prompt diagnosis and appropriate clinical referral and treatment.

    Acute acalculous cholecystitis is a very rare gastrointestinal manifestation in systemic lupus erythematosus and becomes rarer as an initial manifestation. There are only two cases reported. The authors report a 20-year-old black woman that presented acute acalculous cholecystitis revealed by abdominal computed tomography. During hospitalization, she was diagnosed systemic lupus erythematosus. Conservative treatment with antibiotics was performed with complete remission of the symptoms. Corticosteroid was started in ambulatory. Cholecystectomy has been the treatment of choice in acute acalculous cholecystitis as a complication of systemic lupus erythematosus. The patient responded well to conservative treatment, and surgery was not required. This case is unique in the way that corticosteroid was started in ambulatory care. We should not forget that the acute acalculous cholecystitis can be the initial presentation of systemic lupus erythematosus although its occurrence is very rare. Conservative treatment should be considered. Abdominal computed tomography was a determinant exam for better assessment of acute acalculous cholecystitis.

    Human toxocarosis is a chronic larval parasitosis listed as one of the five most important neglected diseases by the CDC. The larvae can spread systemically and migrate to different tissues including liver and gallbladder. Acalculous acute cholecystitis (AAC) is a rare disease in children. The diagnosis is based on clinical parameters and imaging criteria. It has been reported in relation to sepsis, shock, trauma, burns, severe systemic diseases, congenital anomalies, infections and also in healthy children. We report a pediatric case of toxocarosis, with clinical symptoms and imaging criteria compatible with AAC treated medically, and discuss the relationship between toxocarosis and AAC based on published evidence.

    The diagnosis of cystadenoma is rare, even more so when located in the extrahepatic bile duct. Unspecific clinical signs may lead this pathology to be misdiagnosed. The need for pathological anatomy in order to distinguish cystadenomas from simple biliary cysts is crucial.

    Biliary atresia (BA) is a rare disease characterised by a biliary obstruction of unknown origin that presents in the neonatal period. It is the most frequent surgical cause of cholestatic jaundice in this age group. BA occurs in approximately 1/18,000 live births in Western Europe. In the world, the reported incidence varies from 5/100,000 to 32/100,000 live births, and is highest in Asia and the Pacific region. Females are affected slightly more often than males. The common histopathological picture is one of inflammatory damage to the intra- and extrahepatic bile ducts with sclerosis and narrowing or even obliteration of the biliary tree. Untreated, this condition leads to cirrhosis and death within the first years of life. BA is not known to be a hereditary condition. No primary medical treatment is relevant for the management of BA. Once BA suspected, surgical intervention (Kasai portoenterostomy) should be performed as soon as possible as operations performed early in life is more likely to be successful. Liver transplantation may be needed later if the Kasai operation fails to restore the biliary flow or if cirrhotic complications occur. At present, approximately 90% of BA patients survive and the majority have normal quality of life. PMID:16872500

    Cholecystectomy rates for biliary dyskinesia in children are rising in the United States, but not in other countries. Biliary dyskinesia is a validated functional gallbladder disorder in adults, requiring biliary colic in the diagnosis. In contrast, most studies in children require upper abdominal pain, absent gallstones on ultrasound, and an abnormal gallbladder ejection fraction (GBEF) on cholecystokinin-stimulated cholescintigraphy for diagnosis. We aimed to systematically review existing literature in biliary dyskinesia in children, determine the validity and reliability of diagnostic criteria, GBEF, and to assess outcomes following cholecystectomy. We performed a systematic review following the PRISMA checklist and searched 7 databases including PubMed, Scopus, Embase, Ovid, MEDLINE, ProQuest, Web of Science, and the Cochrane library. Bibliographies of articles were screened for additional studies. Our search terms yielded 916 articles of which 28 were included. Three articles were manually added from searched references. We reviewed 31 peer-reviewed publications, all retrospective chart reviews. There was heterogeneity in diagnostic criteria and GBEF values. Outcomes after laparoscopic cholecystectomy varied from 34% to 100% success, and there was no consensus concerning factors influencing outcomes. The observational, retrospective study designs that comprised our review limited interpretation of safety and efficacy of the investigations and treatment in biliary dyskinesia in children. Symptoms of biliary dyskinesia overlapped with functional dyspepsia. There is a need for consensus on symptoms defining biliary dyskinesia, validation of testing required for diagnosis of biliary dyskinesia, and randomized controlled trials comparing medical versus surgical management in children with upper abdominal pain.

    Background The management of chronic abdominal pain after laparoscopic Roux-en-Y gastric bypass (LRYGP) is complex and challenging. Foreign body intestinal perforation including that caused by fish bones has previously been reported in the literature and if clinically unrecognized, can cause significant morbidity and mortality. Fish bone perforation as a cause of chronic abdominal pain after LRYGP has rarely been reported. Summary The unusual case of a 54 year old female presenting with recurrent episodes of postprandial pain 2 years after LRYGP is reported. Previous radiological and endoscopic investigations did not reveal any abnormality and after the most recent clinical presentation, a laparoscopic exploration was performed. A protruding fish bone at the biliary-digestive junction was discovered intra-operatively and successfully extracted. Dense adhesions between the involved intestinal loops were lysed in an attempt to improve intestinal transit and subsequently relieve post-prandial pain. Conclusion This case highlights the possibility of a missed fish bone perforation causing chronic postprandial abdominal pain and discomfort in a patient with a Roux-en-Y gastric bypass anatomy. Foreign body perforation is a rare cause of abdominal pain after gastric bypass that should be considered when evaluating chronic abdominal pain symptoms after LRYGP. PMID:27107305

    Acalculous cholecystitis and cholangitis are increasingly being recognized as complications of AIDS. The opportunistic parasites that have been most commonly associated with these disorders are Cryptosporidium species, Isospora belli, Cyclospora cayetanensis and Enterocytozoon bieneusi. The authors performed a parasitological survey on the gallbladder tissue sections of patients underwent cholecystectomy due to chronic acalculous cholecystitis at the Shiraz University of Medical Sciences, Iran. Light microscopic investigation in more than three hundred archived histopathological slides revealed the presence of sexual stages (i.e., mature sporocysts) of a coccidial protozoan in a patient with AIDS who developed acalculous cholecystitis as confirmed by histological, parasitological and molecular tests in which Sarcocystis species was the only identifiable pathogen in gallbladder sections. In the best of our knowledge it's the first documented case of chronic non-calculous cholecystitis due to Sarcocystis parasite in an Iranian AIDS patient from worldwide.

    Extrahepatic biliary atresia (EHBA), an inflammatory sclerosing cholangiopathy, is the leading indication for liver transplantation in children. The cause is still unknown, although possible infectious, genetic, and immunologic etiologies have received much recent focus. These theories are often dependent on each other for secondary or coexisting mechanisms. Concern for EHBA is raised by a cholestatic infant, but the differential diagnosis is large and the path to diagnosis remains varied. Current treatment is surgical with an overall survival rate of approximately 90%. The goals of this article are to review the important clinical aspects of EHBA and to highlight some of the more recent scientific and clinical developments contributing to our understanding of this condition.

    Acute acalculous cholecystitis (AAC) can be defined as acute inflammatory disease of the gallbladder without evidence of gallstones. The first case was reported in 1844 by Duncan et al.; however, some cases may have been missed previously in view of the complexity of the diagnosis. Several risk factors have been identified, and cardiovascular disease (CVD), in view of its multiple mechanisms of action, seems to play a key role. Atypical clinical onset, paucity of symptoms, overlap with comorbidities, and lack of robust, controlled trials result often in under or misdiagnosed cases. Moreover, laboratory results may be negative or not specific in the late stage of the disease, when a surgical treatment cannot be longer helpful if complications arise. A rapid diagnosis is therefore essential to achieve a prompt treatment and to avoid further clinical deterioration. In this short review, we would present the current evidence regarding epidemiology, pathophysiology, and clinical presentation of the complex relation between AAC and CVD. Then, we fully emphasize the role of ultrasound to achieve an early diagnosis and an appropriate treatment in suspected cases, reducing mortality and complications rates.

    Plastic biliary endoprostheses have not changed much since their introduction more than 3 decades ago. Although their use has been challenged by the introduction of metal stents, plastic stents still remain commonly used. Much work has been done to improve the problem of stent obstruction but without substantial clinical success. In this review, the authors discuss the history of plastic biliary stent development and the current use of plastic stents for malignant biliary diseases.

    Foreign bodies in the biliary tree are rare causes of obstructive jaundice. Food bezoars are infrequent as well. They can cause biliary obstruction after biliary tract interventions, or in the presence of biliary-bowel fistula or duodenum diverticulum. Food bezoars usually pass the gastrointestinal tract without any symptoms, but they can cause abdominal pain and obstructive jaundice in the case of biliary tract obstruction. Endoscopic retrograde cholangio-pancreatography has the major role in the diagnosis and the treatment of the disease. Authors summarize the medical history of a 91-year-old female patient, who developed vomiting and right subcostal pain due to the presence of tomato peel within the ductus choledochus.

    Acute acalculous cholecystitis has a high mortality rate due to the difficulties in early diagnosis and high rate of complications like empyema, gangrene and perforation. We report a case of 20-year-old male with acute severe pancreatitis, acute renal failure and acute peripancreatic fluid collection who was transferred to our department after blood filtration treatment in ICU. After percutaneous catheter drainage for 20 hours, the patient got a high fever. Computed tomography revealed retroperitoneal colon injury. In this case, percutaneous catheter drainage was performed again and the pus cavity was flushed regularly, after which the patient’s state gradually improved. Unpredictably, septic shock appeared on the 51st day. Repeated computed tomography revealed acute acalculous cholecystitis and abscess formation. After percutaneous transhepatic gallbladder catheterization and drainage, the patient got better gradually. Three months later the retroperitoneal catheter was removed. Four months later, ultrasound examination showed normal gallbladder and the catheter was removed. PMID:26131252

One case in which the gallbladder was visualized failed to respond to sincalide stimulation; this was classified as a suggestive finding of disease. The diagnostic accuracy of /sup 99m/Tc-IDA cholescintigraphy was far superior to the other imaging studies used (8 sonograms, 1 intravenous cholangiogram, 3 oral cholecystograms, 1 percutaneous transhepatic cholangiogram). The /sup 99m/Tc-IDA study is recommended as the imaging procedure of choice for examining patients with suspected acute acalculous cholecystitis.

    Cholecystitis is one of the common surgical indications affecting human beings in many countries. A variety of infectious agents can be associated with acute or chronic acalculous cholecystitis, especially in HIV/AIDS patients. In this investigation, the authors aim to describe two cases of histologically and molecularly documented cystoisosporiasis (syn. isosporiasis) as the cause of chronic acalculous cholecystitis in two immunodeficient patients. During microscopic examinations of more than 2500 diarrheic patients' samples, 11 cases of cystoisosporiasis-related recurrent persistent/chronic diarrhea were detected. A review of the medical records of Cystoisospora belli (syn. Isospora belli)-positive patients showed that two of them, i.e. a patient with prolonged corticosteroid therapy and an AIDS patient, several months prior to fecal examinations had undergone cholecystectomy due to acalculous cholecystitis. The study was continued by a review of the histopathological investigation of the recuts prepared from the excised gallbladder tissue sections and stained with hematoxylin and eosin in order to detect a possible specific clinical correlation with cystoisosporiasis. Light microscopic examination revealed the presence of various developmental stages of a coccidial parasite, namely Cystoisospora belli, in both patients' gallbladder tissue sections. To the best of our knowledge, C. bellii-associated cholecystitis has not been previously reported in a patient with prolonged corticosteroid therapy.

    Portal biliopathy is defined as abnormalities in the extra- and intrahepatic ducts and gallbladder of patients with portal hypertension. This condition is associated with extrahepatic venous obstruction and dilatation of the venous plexus of the common bile duct, resulting in mural irregularities and compression of the biliary tree. Most patients with portal biliopathy remain asymptomatic, but approximately 10% of them advance to symptomatic abdominal pain, jaundice, and fever. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography are currently used as diagnostic tools because they are noninvasive and can be used to assess the regularity, length, and degree of bile duct narrowing. Management of portal biliopathy is aimed at biliary decompression and reducing the portal pressure. Portal biliopathy has rarely been reported in Korea. We present a symptomatic case of portal biliopathy that was complicated by cholangitis and successfully treated with biliary endoscopic procedures.

    Biliary cast syndrome (BCS) is an uncommon complication which is mostly described in orthotopic liver transplantation. However, BCS has also been reported rarely in non-liver transplant patients. We describe a male long-term opium inhaler with BCS who underwent successful endoscopic cast removal by balloon enteroscopy-guided endoscopic retrograde cholangiopancreatography. A 52-year-old man, who was a known case of opium addiction, presented with the chief complaint of epigastric pain for 1 week prior to admission. Routine laboratory evaluation revealed cholestatic liver enzyme elevation. A cholestatic pattern was seen in radiographic modalities. Endoscopic retrograde cholangiopancreatography showed a linear filling defect in the intra- and extrahepatic duct. A long biliary cast was successfully removed using an extractor balloon. After removal of the biliary cast the patient is receiving ursodeoxycholic acid and does not report any problem 4 months after treatment. It seems that biliary dyskinesia due to long-term opium use can be a predisposing factor for biliary cast formation. PMID:24163648

  2. The role of sonography in imaging of the biliary tract.

    PubMed

    2007-06-01

    Sonography is the recommended initial imaging test in the evaluation of patients presenting with right upper quadrant pain or jaundice. Dependent upon clinical circumstances, the differential diagnosis includes choledocholithiasis, biliary stricture, or tumor. Sonography is very sensitive in detection of mechanical biliary obstruction and stone disease, although less sensitive for detection of obstructing tumors, including pancreatic carcinoma and cholangiocarcinoma. In patients with sonographically documented cholelithiasis and choledocholithiasis, laparoscopic cholecystectomy with operative clearance of the biliary stone disease is usually performed. In patients with clinically suspected biliary stone disease, without initial sonographic documentation of choledocholithiasis, endoscopic ultrasound or magnetic resonance cholangiopancreatography is the next logical imaging step. Endoscopic ultrasound documentation of choledocholithiasis in a postcholecystectomy patient should lead to retrograde cholangiography, sphincterotomy, and clearance of the ductal calculi by endoscopic catheter techniques. In patients with clinical and sonographic findings suggestive of malignant biliary obstruction, a multipass contrast-enhanced computed tomography (CT) examination to detect and stage possible pancreatic carcinoma, cholangiocarcinoma, or periductal neoplasm is usually recommended. Assessment of tumor resectability and staging can be performed by CT or a combination of CT and endoscopic ultrasound, the latter often combined with fine needle aspiration biopsy of suspected periductal tumor. In patients whose CT scan suggests hepatic hilar or central intrahepatic biliary tumor, percutaneous cholangiography and transhepatic biliary stent placement is usually followed by brushing or fluoroscopically directed fine needle aspiration biopsy for tissue diagnosis. Sonography is the imaging procedure of choice for biliary tract intervention, including cholecystostomy, guidance for

    Primary biliary cirrhosis is a chronic cholestatic liver disease characterised by destruction of small intrahepatic bile ducts, leading to fibrosis and potential cirrhosis through resulting complications. The serological hallmark of primary biliary cirrhosis is the antimitochondrial antibody, a highly disease-specific antibody identified in about 95% of patients with primary biliary cirrhosis. These patients usually have fatigue and pruritus, both of which occur independently of disease severity. The typical course of primary biliary cirrhosis has changed substantially with the introduöction of ursodeoxycholic acid (UDCA). Several randomised placebo-controlled studies have shown that UDCA improves transplant-free survival in primary biliary cirrhosis. However, about 40% of patients do not have a biochemical response to UDCA and would benefit from new therapies. Liver transplantation is a life-saving surgery with excellent outcomes for those with decompensated cirrhosis. Meanwhile, research on nuclear receptor hormones has led to the development of exciting new potential treatments. This Seminar will review the current understanding of the epidemiology, pathogenesis, and natural history of primary biliary cirrhosis, discuss management of the disease and its sequelae, and introduce research on new therapeutic options.

    A captive 3-mo-old white African lion (Panthera leo) presented with clinical signs of acute pain and a distended abdomen. Despite emergency treatment, the lion died a few hours after presentation. Postmortem examination revealed gross changes in the liver, spleen, and lungs and an anomalous cystic structure in the bile duct. Histologic examination identified severe generalized multifocal to coalescent necrotizing and neutrophilic hepatitis, neutrophilic splenitis, and mild interstitial pneumonia, consistent with bacterial septicemia. The abnormal biliary structures resembled biliary cystadenoma. However, due to the age of the animal, they were presumed to be congenital in origin. Biliary tract anomalies and cystadenomas have been reported previously in adult lions, and this case suggests that at least some of these examples may have a congenital basis. It is unclear whether the lesion was an underlying factor in the development of hepatitis.

    Background and study aims: Endoscopic retrograde pancreatocholangiography (ERCP) is associated with many types of adverse events (AEs) but idiopathic perforation of the gallbladder (IPGB) is very rare. Pancreatobiliary reflux is one of the factors involved with occurrence of IPGB 1. Here we present a case of acalculous gallbladder perforation as an AE following the insertion of an indwelling endoscopic nasal pancreatic drainage (ENPD) tube (a pancreatic stent) to obtain pancreatic fluid. In this case, acute pancreatobiliary reflux might have been caused by the insertion of the ENPD-tube. PMID:27540570

    Acute acalculous cholecystitis (AAC) is a rare complication of infectious mononucleosis (IM). An immunocompetent 6-year-old Japanese girl complained of epigastralgia during the course of IM. Ultrasonography (US) revealed a markedly thickened and sonolucent gallbladder wall. No gallstones were apparent. Antibodies against Epstein-Barr virus (EBV) confirmed primary EBV infection. Cytomegalovirus immunoglobulin M showed a false-positive result in the acute phase, probably due to cross-reaction to EBV nuclear antigen. We diagnosed her as AAC related with primary EBV infection. She recovered completely by conservative treatment. US should be performed in consideration of the possibility of AAC when a patient with IM complains of epigastralgia.

    Abstract Rationale: Ascariasis is an endemic parasitic disease caused by Ascaris lumbricoides, which severely burdens the healthcare system as well as harms the personal life quality, especially among less developed regions. Biliary ascariasis is a critical complication of intestinal ascariasis with painful and life-threatening manifestations. The exploration of proper strategies as its medical interventions remains largely controversial. Patient concerns: A 16 year-old patient complained of abdominal pain and yellow sclera. Diagnoses: Biliary ascariasis Interventions: Laparoscopic cholecystectomy and bile duct exploration. Outcomes: More than one hundred ascarids were extracted and the patient had been discharged from hospital without any complications. Lessons: The combination of laparoscope and choledochoscope is an efficient method to treat biliary ascariasis, despite of large worm burden in the common bile duct. PMID:28353561

    This case reveals the complexities and challenges in the diagnosis of acute Epstein-Barr virus (EBV) infection, indicating the potential relationship between EBV infection and severe icteric hepatitis, acalculous cholecystitis, and lymphocytic vasculitis. We suggest including EBV infectious mononucleosis in the list of differential diagnoses when any of these clinical syndromes (or a combination thereof) occurs without apparent cause, especially in the presence of lymphocytosis. To our knowledge, this is the first report to suggest the possible role of EBV in the pathogenesis of cutaneous lymphocytic vasculitis. Also it is possible that EBV infection triggered the flare-up of the underlying rheumatologic disease. Therefore, it could be assumed that a part of the clinical syndrome (e.g., dermatologic manifestations) might be related to the flare-up of the underlying rheumatologic disease. PMID:27847520

    2013-01-01

    Biliary stenting has evolved dramatically over the past 30 years. Advancements in stent design have led to prolonged patency and improved efficacy. However, biliary stenting is still affected by occlusion, migration, anatomical difficulties, and the need for repeat procedures. Multiple novel plastic biliary stent designs have recently been introduced with the primary goals of reduced migration and improved ease of placement. Self-expandable bioabsorbable stents are currently being investigated in animal models. Although not US Food and Drug Administration approved for benign disease, fully covered self-expandable metal stents are increasingly being used in a variety of benign biliary conditions. In malignant disease, developments are being made to improve ease of placement and stent patency for both hilar and distal biliary strictures. The purpose of this review is to describe recent developments and future directions of biliary stenting. PMID:23837001

  13. External biliary fistula.

    PubMed

    Sharma, A K

    2001-01-01

    A biliary fistula is almost invariably related to gallstone disease and commonly follows a hurried cholecystectomy by an inexperienced surgeon. This catastrophy which is largely preventable, often necessitates repeated surgical intervention and accrues an estimated 5-year mortality rate approaching 30%. Published series only show a slight increase in the incidence (one per 150-200) after laparoscopic cholecystectomy. The injury results from imprecise dissection and inadequate demonstration of the anatomical structures. The diagnosis is usually obvious and persistent tachycardia and hypotension inspite of an adequate intravenous infusion and a normal central venous pressure is another well known indicator of subhepatic collection of bile, which indicates an urgent ultrasonographic scanning of the upper abodmen. ERCP is a useful diagnostic and therapeutic tool when the continuity of the extra-hepatic biliary system has not been disrupted. An endobiliary stent can be placed across the defect in the same sitting, to tide over the immediate crisis and perhaps treat the patient on a permanent basis. Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive technique of outlining both the intra and extrahepatic biliary tree, which can provide a better road map of the fistula than an ERCP. The management has to be tailored to the patient's condition and the expertise available. A bilio-enteric anastomosis, performed 4 to 6 months after the initial surgery on a dilated common hepatic duct is more likely to succeed than an operation on a septic, hypoproteinemic patient with sodden, friable, non-dilated bile ducts. On the other hand, waiting for the ducts to dilate in a patient with a complete transection of the bile ducts with complete biliary diversion only leads to depletion of the bile acid pool, severe electrolyte derangement and nutritional failure, leading on to sepsis and death.

  14. Direct cholangiography and biliary drainage.

    PubMed

    Burcharth, F; Kruse, A

    1996-01-01

    Direct cholangiography by percutaneous transhepatic cholangiography or endoscopic retrograde cholangiography has greatly improved diagnostic work-up of patients with known or suspected biliary obstruction. These diagnostic procedures were introduced in Denmark in the early 1970s, and technical refinements and clinical research of the methods were initiated. The Danish contribution led to definition of indications for direct cholangiography and general acceptance of the methods in daily clinical practice; nationally as well as internationally. The transhepatic cholangiography with selective catheterization of the biliary ducts permitted external drainage of obstructed ducts. The disadvantages of this technique inspired the innovation of internal biliary drainage and the invention of the biliary endoprosthesis. The endoscopic approach to the biliary tract and the technical improvements of accessory instruments led to the early introduction of therapeutic procedures, i.e. papillotomy, stone removal, biliary drainage and treatment of strictures and post-traumatic lesions. Experimental and clinical research with endoprostheses improved their function and prevented dislodgment. Clinical research documented that biliary drainage by endoprosthesis is a valuable alternative to surgical bypass in patients with inoperable biliary obstructions. Endoscopic therapeutic procedures for common bile duct stones have almost replaced conventional surgical treatment. Endoluminal imaging techniques are under evaluation and may contribute to future improvements.

    Autoimmune biliary diseases are poorly understood but important to recognize. Initially, autoimmune biliary diseases are asymptomatic but may lead to progressive cholestasis with associated ductopenia, portal hypertension, cirrhosis, and eventually liver failure. The three main forms of autoimmune biliary disease are primary biliary cirrhosis, primary sclerosing cholangitis, and IgG4-associated cholangitis. Although some overlap may occur between the three main autoimmune diseases of the bile ducts, each disease typically affects a distinct demographic group and requires a disease-specific diagnostic workup. For all the autoimmune biliary diseases, imaging provides a means to monitor disease progression, assess for complications, and screen for the development of hepatobiliary malignancies that are known to affect patients with these diseases. Imaging is also useful to suggest or corroborate the diagnosis of primary sclerosing cholangitis and IgG4-associated cholangitis. We review the current literature and emphasize radiological findings and considerations for these autoimmune diseases of the bile ducts.

  16. Biliary atresia in lampreys.

    The preceding pages have described an organism that is far removed from mammals on the taxonomic scale of vertebrates but one that has proven to have a unique and most useful system for studies of liver function and, in particular, bile product transport and excretion. It is also an organism in which iron loading can be studied in the liver and other organs and tissues. Many of the events that occur in this animal during its life cycle with regard to bile pigment metabolism as normal programmed phenomena are unparalleled among the vertebrates. In the larval (ammocoete) period of lampreys, there is an intrahepatic gallbladder and a biliary tree that is well equipped for the storage, transport, and elimination of bile products into the intestine for ultimate excretion with the feces. The importance of the patency of these bile ducts to bile excretion is illustrated in one species of lampreys in which the bile ducts of young ammocoetes become infested with larval nematodes to a degree that bile pigment regurgitation into the blood results in a green serum that is identified as biliverdin. Despite having serum levels of biliverdin that would be toxic to humans, these individuals live a complete larval life. The larvae of all lamprey species undergo a phase of metamorphosis in which they transform into adults. During this phase the larval gallbladder, the bile canaliculi of the hepatocytes, and all the intrahepatic bile ducts completely regress in a developmental process called lamprey biliary atresia. The epithelium of the extrahepatic common bile duct transforms and expands into a caudal portion of the endocrine pancreas of the adult. Many of the events of lamprey biliary atresia resemble events occurring during experimental and pathological conditions of mammalian cholestasis, including disruption to the bile-blood barrier (intercellular junctions), accumulation of bile components in the cytoplasmic inclusions, and alteration of the distribution of membrane enzymes

    Impaired smooth muscle contractility is a hallmark of acute acalculous cholecystitis. Although free cytosolic Ca2+ ([Ca2+]i) is a critical step in smooth muscle contraction, possible alterations in Ca2+ homeostasis by cholecystitis have not been elucidated. Our aim was to elucidate changes in the Ca2+ signaling pathways induced by this gallbladder dysfunction. [Ca2+]i was determined by epifluorescence microscopy in fura 2-loaded isolated gallbladder smooth muscle cells, and isometric tension was recorded from gallbladder muscle strips. F-actin content was quantified by confocal microscopy. Ca2+ responses to the inositol trisphosphate (InsP3) mobilizing agonist CCK and to caffeine, an activator of the ryanodine receptors, were impaired in cholecystitic cells. This impairment was not the result of a decrease in the size of the releasable pool. Inflammation also inhibited Ca2+ influx through L-type Ca2+ channels and capacitative Ca2+ entry induced by depletion of intracellular Ca2+ pools. In addition, the pharmacological phenotype of these channels was altered in cholecystitic cells. Inflammation impaired contractility further than Ca2+ signal attenuation, which could be related to the decrease in F-actin that was detected in cholecystitic smooth muscle cells. These findings indicate that cholecystitis decreases both Ca2+ release and Ca2+ influx in gallbladder smooth muscle, but a loss in the sensitivity of the contractile machinery to Ca2+ may also be responsible for the impairment in gallbladder contractility.

    Biliary atresia is the most common cause of pediatric end-stage liver disease and the leading indication for pediatric liver transplantation. Affected infants exhibit evidence of biliary obstruction within the first few weeks after birth. Early diagnosis and successful surgical drainage of bile are associated with greater survival with the child's native liver. Unfortunately, because noncholestatic jaundice is extremely common in early infancy, it is difficult to identify the rare infant with cholestatic jaundice who has biliary atresia. Hence, the need for timely diagnosis of this disease warrants a discussion of the feasibility of screening for biliary atresia to improve outcomes. Herein, newborn screening for biliary atresia in the United States is assessed by using criteria established by the Discretionary Advisory Committee on Heritable Disorders in Newborns and Children. Published analyses indicate that newborn screening for biliary atresia by using serum bilirubin concentrations or stool color cards is potentially life-saving and cost-effective. Further studies are necessary to evaluate the feasibility, effectiveness, and costs of potential screening strategies for early identification of biliary atresia in the United States.

    Patients with chronic right upper quadrant pain who do not have gallstones on ultrasound or cholecystography are often referred for surgery for presumed acalculous chronic cholecystitis. We followed 26 patients who had cholecystokinin (CCK) cholescintigraphy for evaluation of chronic right upper quadrant pain without demonstrable gallstones on ultrasound who underwent cholecystectomy so that it could be determined whether there was any relation between a low ejection fraction (EF), morphological features of chronic cholecystitis, and clinical outcome. Eighteen patients (69%) were considered therapeutic successes, whereas eight (31%) were failures after an average 2-yr follow-up. Both patient groups had significantly reduced EF: the successful group at 0.39 and the failures at 0.25. Thus, a low EF did not predict clinical outcome, since the failure group had an even lower EF than the success group. Seven gallbladders demonstrated chronic acalculous cholecystitis; the average EF of this group was 0.35. The remaining 19 gallbladders were normal, yet also had an EF of 0.35. Thus, decreased EF does not predict the histologic features of chronic cholecystitis without gallstones. The diagnostic value of cholescintigraphy in patients with acalculous right upper quadrant pain is low, probably because this entity represents a variety of processes, including inflammation, gallbladder dysmotility, and the irritable bowel syndrome.

  20. Age, Predisposing Diseases, and Ultrasonographic Findings in Determining Clinical Outcome of Acute Acalculous Inflammatory Gallbladder Diseases in Children

    2016-01-01

    We evaluated clinical factors such as age, gender, predisposing diseases and ultrasonographic findings that determine clinical outcome of acute acalculous inflammatory gallbladder diseases in children. The patients were divided into the four age groups. From March 2004 through February 2014, clinical data from 131 children diagnosed as acute acalculous inflammatory gallbladder disease by ultrasonography were retrospectively reviewed. Systemic infectious diseases were the most common etiology of acute inflammatory gallbladder disease in children and were identified in 50 patients (38.2%). Kawasaki disease was the most common predisposing disease (28 patients, 21.4%). The incidence was highest in infancy and lowest in adolescence. The age groups were associated with different predisposing diseases; noninfectious systemic disease was the most common etiology in infancy and early childhood, whereas systemic infectious disease was the most common in middle childhood and adolescence (P = 0.001). Gallbladder wall thickening was more commonly found in malignancy (100%) and systemic infection (94.0%) (P = 0.002), whereas gallbladder distension was more frequent in noninfectious systemic diseases (60%) (P = 0.000). Ascites seen on ultrasonography was associated with a worse clinical course compared with no ascites (77.9% vs. 37.7%, P = 0.030), and the duration of hospitalization was longer in patients with ascites (11.6 ± 10.7 vs. 8.0 ± 6.6 days, P = 0.020). In conclusion, consideration of age and predisposing disease in addition to ultrasonographic gallbladder findings in children suspected of acute acalculous inflammatory gallbladder disease might result in better outcomes.

    There are many studies about the biliary stents, however there is a little information about the long-term stayed forgotten biliary stents except a few case reports. We have reported the results of a number of cases with biliary stents that were forgotten or omitted by the patient and the endoscopist. During February 2010 to May 2013, five patients were referred to the general surgery clinic of Haydarpasa Numune Training and Research Hospital, Istanbul Turkey. Past history and medical documents submitted by the patient did not indicate a replacement of the biliary stent in 3 patients. Two patients knew that they had biliary stents. We also conducted a literature review via the PubMed and Google Scholar databases of English language studies published until March 2014 on forgotten biliary stent. There were 3 men and 2 women ranging in age from 22 to 68 years (mean age 41.6 years). Patients presented with pain in the upper abdomen, jaundice, fever, abnormal liver function tests or dilatation of the biliary tract alone or in combination. Patients' demographic findings are presented in Table 1. A review of three cases reported in the English medical literature also discussed. The mean duration of the patency of the stent is about 12 months. The biliary stenting is performed either with plastic or metal stents, studies recommending their replacement after 3-6 months. Patients with long stayed forgotten biliary stents are inevitably treated with surgical intervention. We recommend for all endoscopic retrograde cholangiopancreatography units provide a stent registry system that the stents placed for various therapeutic procedures are not forgotten both by the patient as well as the physician. There should be a deadline for biliary stents in the registry system for each patient.

    Significant pain can occur after removing transhepatic catheters from biliary access tracks, after percutaneous biliary drainage (PBD) or stenting. We undertook a randomized prospective study to ascertain whether track embolization decreases the amount of pain or analgesic requirement after PBD. Fifty consecutive patients (M:F, 22:28; age range:29-85 years; mean age: 66.3 years) undergoing PBD were randomized to receive track embolization or no track embolization after removal of biliary drainage catheters. A combination of Lipoidol and n-butyl cyanoacrylate were used to embolize transhepatic tracks using an 8F dilator. The patients who did not have track embolization performed had biliary drainage catheters removed over a guide wire. A visual analog scoring (VAS) system was used to grade pain associated with catheter removal, 24 h afterward. A required analgesic score (RAS) was devised to tabulate the analgesia required. No analgesia had a score of 0, oral or rectal nonopiate analgesics had a score of 1, oral opiates had a score of 2, and parenteral opiates had a score of 3. The average VAS and RAS for both groups were calculated and compared.Seven patients were excluded for various reasons, leaving 43 patients in the study group. Twenty-one patients comprised the embolization group and 22 patients comprised the nonembolization group. The mean biliary catheter dwell time was not significantly different (p > 0.05) between the embolization group and nonembolization (mean: 5.4 days vs 6.9 days, respectively). In the nonembolization group, the mean VAS was 3.4. Eight patients required parenteral opiates, three patients required oral opiates, and five patients required oral or rectal analgesics, yielding a mean RAS of 1.6. In the embolization group, the mean VAS was 0.9. No patient required parenteral opiates, six patients required oral opiates, and two patients had oral analgesia. The average RAS was 0.6. Both the VAS and the RAS were significantly lower in the

    AIM To review the evidence for the use of different non-steroidal anti-inflammatory drugs (NSAIDs) in the treatment of biliary colic. METHODS The strategies employed included an extensive literature review for articles and studies related to biliary colic from electronic databases including PubMed, Science Direct, Wiley Inter Science, Medline and Cochrane from last 15 years. Keywords: “Biliary colic”, “management of biliary colic”, “non-steroidal anti-inflammatory drugs”, “cholelithiasis” and “biliary colic management”. Six randomized control trials, 1 non-randomized trial and 1 meta-analysis were included in this review. The outcomes of these studies and their significance have been reviewed in this paper. RESULTS Current evidence suggests there are no set protocols for biliary colic pain management. NSAIDs are potent in the management of biliary colic, not only in terms of symptom control but in disease progression as well. Apart from the studies on diclofenac and ketorolac, there are studies which have shown that intravenous tenoxicam and injectable flurbiprofen are equally effective in managing biliary colic. The efficacy of NSAIDs is superior in terms of lower number of doses and longer duration of action in comparison to other analgesic agents. CONCLUSION This literature review has found that NSAIDs are safe and effective for pain control in biliary colic, and reduce the likelihood of further complications. PMID:27830044

    Introduction Epithelial corrective and destructive mechanisms have not been studied in inflammatory gallbladder disease. Methods Epithelial apoptosis, cell proliferation and expression of hypoxia-inducible factor (HIF)-1α were compared in gallbladders from patients with acute acalculous cholecystitis (AAC; n = 30) and acute calculous cholecystitis (ACC; n = 21), and from patients undergoing surgery for other reasons (normal gallbladders; n = 9), which were removed during open cholecystectomy. The immunohistochemical stains included antibodies to Ki-67 (proliferation), M30 (apoptosis) and HIF-1α. Proliferation and apoptosis were expressed as percentages of positive cells. HIF-1α expression was expressed as absent, weak, or strong. Results Apoptosis (median [25th to 75th percentile]) was significantly increased in AAC (1.31% [0.75% to 1.8%], P < 0.001) and ACC (1.10% [0.63% to 1.64%], P = 0.001), compared with control samples (0.20% [0.07% to 0.45%]. The proliferation rate was significantly increased in AAC (8.0% [4.0% to 17.0%], P < 0.001) and ACC (14% [7.5% to 26.5%], P = 0.001) compared with control samples (1.0% [1.0% to 3.0%]). Strong HIF-1α staining was observed in 57% of AAC, in 100% of ACC and in 44% of control specimens (P < 0.001). Intense HIF-1α expression was associated with increased cell proliferation (P = 0.002). Conclusion Cell proliferation and apoptosis were increased in AAC and ACC, as compared with normal gallbladders. Expression of HIF-1α was lower in AAC than in ACC. PMID:17974017

    Endobiliary radiofrequency ablation (RFA) has recently been recognized as a beneficial treatment option for malignant biliary obstruction using percutaneous or endoscopic approaches. The feasibility and safety of this method has been demonstrated in clinical studies, with pain, cholangitis and asymptomatic biochemical pancreatitis reported as relatively common complications. By contrast, hepatic coma, newly diagnosed left bundle branch block and partial liver infarction have been reported as uncommon complications. Biliary tract perforation is a serious potential complication of percutaneous intraductal RFA, which may result in severe infection, peritonitis or even mortality, and which has not been previously reported in clinical research. The current study presents the first reports of biliary tract perforation in two patients with unresectable malignant biliary obstruction following percutaneous intraductal RFA. Although the patient in case 1 succumbed 12 days after RFA, the minor biliary tract perforation in case 2 was successfully treated by the deployment of a self-expanding metal stent. This study demonstrates that biliary tract perforation should be recognized as a serious potential complication of endobiliary RFA, and that metal stent deployment should be considered as a treatment option for minor biliary tract perforation.

    Background: Biliary complications remain a significant problem following liver transplantation. Several surgical options can be used to deal with a significant size mismatch between the donor and recipient bile ducts during the biliary anastomosis. We compared biliary transposition to recipient biliary ductoplasty in cadaveric liver transplant. Methods: A total of 33 reconstructions were performed from January 1, 2005 to December 31, 2013. In the biliary transposition group (n=23), 5 reconstructions were performed using an internal stent (5 or 8 French pediatric feeding tube), and 18 were performed without. Of the 10 biliary ductoplasties, 2 were performed with a stent. All patients were managed with standard immunosuppression and ursodiol. Follow-up ranged from 2 months to 5 years. Results: No patients in the biliary transposition group required reoperation; 1 patient had an internal stent removed for recurrent unexplained leukocytosis, and 2 patients required endoscopic retrograde cholangiography and stent placement for evidence of stricture. Three anastomotic leaks occurred in the biliary ductoplasty group, and 2 patients in the biliary ductoplasty group required reoperation for biliary complications. Conclusion: Our results indicate that biliary reconstruction can be performed with either biliary transposition or biliary ductoplasty. These techniques are particularly useful when a significant mismatch in diameter exists between the donor and recipient bile ducts. PMID:28331447

    The techniques that have come into general use for diagnosing problems of obstructive jaundice, particularly in the past ten years, have been ultrasonography, computerized tomography, radionuclide imaging, transhepatic percutaneous cholangiography using a long thin needle, transhepatic percutaneous drainage for obstructive jaundice due to malignancy, endoscopic retrograde cannulation of the papilla (ERCP), endoscopic sphincterotomy and choledochoscopy. It is helpful to review obstructive jaundice due to gallstones from a clinical point of view and the use of the directable stone basket for the retrieval of retained stones, choledochoscopy for the same purpose using the rigid versus flexible choledochoscopes and dissolution of stones using various fluids through a T tube. The use of dilation of the sphincter for the treatment of stenosis or stricture of the bile duct is now frowned on; rather, treatment choices are between the use of sphincteroplasty versus choledochoduodenostomy and choledochojejunostomy. Any patient with obstructive jaundice or anyone undergoing manipulation of the bile ducts should have prophylactic antibiotic therapy. The current literature regarding treatment of cancer of the bile ducts is principally devoted to the new ideas relative to treatment of tumors of the upper third, especially the bifurcation tumors that are now being resected rather than bypassed. Tumors of the distal bile duct are still being resected by focal operations. Finally, it is now felt that early operation for congenital biliary atresia and choledochal cysts gives the best prognosis, with preoperative diagnosis now possible with the use of ultrasonography and ERCP.

    AIM To evaluate the diagnostic value of serial biochemical blood tests in the diagnosis of biliary colic. METHODS Files were reviewed of 1039 patients who were admitted to the Share’e Zedek Medical Center emergency department between the years 2012-2013, and received the coding of acute biliary disease. Of these, the first 100 cases were selected that met the following criteria: (1) a diagnosis of biliary colic or symptomatic cholelithiasis; (2) at least two biochemical blood tests performed; and (3) 18 years of age or older. Patients with other acute biliary diseases were excluded. The biochemical profile of the patients was analyzed as were their clinical and radiological findings. RESULTS Three-quarters of the patients were women, whose average age of 37 years was younger than the average of the men, at 50 years. According to their histories, 47% of the patients had previously known cholelithiasis. Pain in either the right upper quadrant or the epigastrium was the presenting symptom in 93% cases. The greatest change in serum biochemical results was seen during the first day of the patients’ admissions. Alanine aminotransferase (ALT) showed the highest initial rise above the reference range, followed by aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), bilirubin and alkaline phosphatase (ALKP) - all these increases were statistically significant (P < 0.05). AST showed the sharpest decline followed by bilirubin and ALT. GGT and ALKP did not fall. A sharp rise and fall in liver enzymes, especially during the first day, most prominently in AST and ALT, was seen in 70% percent of cases. In 65% of cases trans-abdominal sonography did not give diagnostic findings. CONCLUSION Serial serum liver enzyme measurements are helpful in the initial diagnosis of acute biliary colic.

    Polysplenia syndrome is a rare malformation characterized by the association of multiple rates and other congenital anomalies dominated by cardiac, vascular, intestinal and bile malformations. We report the observation of a patient operated in the neonatal period (3 days) for an upper intestinal obstruction with situs inversus. Surgical exploration noted the presence of multiple rates, a preduodenal vein, a biliary atresia and a duodenal atresia. The surgical procedures performed were a latero-lateral duodeno-duodenostomy and hepatoportoenterostomy of KASAI with simple immediate and delayed outcomes. The follow up was of 23 years. We recall the epidemiological characteristics of this malformative association and we discuss the role played by the prognosis of polysplenia syndrome in the evolution of biliary atresia. The diagnosis and treatment of biliary atresia are always urgent to increase the chances of success of the Kasai, and the chances of prolonged survival with native liver. However, almost all long-term survivors (even anicteric) have biliary cirrhosis, which requires lifelong follow up.

    Benign biliary strictures are most commonly a consequence of injury at laparoscopic cholecystectomy or fibrosis after biliary-enteric anastomosis. These strictures are notoriously difficult to treat and traditionally are managed by resection and fashioning of acholedocho- or hepato-jejunostomy. Promising results are being achieved with newer minimally invasive techniques using endoscopic or percutaneous dilatation and/or stenting and these are likely to play an increasing role in the management. Even low-grade biliary obstruction carries the risks of stone formation, ascending cholangitis and hepatic cirrhosis and it is important to identify and treat this group of patients. There is currently no consensus on which patient should have what type of procedure, and the full range of techniques may not be available in all hospitals. Careful assessment of the risks and likely benefits have to be made on an individual basis. This article reviews the current literature and discusses the options available. The techniques of endoscopic and percutaneous dilatation and stenting are described with evaluation of the likely success and complication rates and compared to the gold standard of biliary-enteric anastomosis.

    Biliary bacteria have been implicated in gallstone pathogenesis, though a clear understanding of their composition and source is lacking. Moreover, the effects of the biliary environment, which is known to be generally hostile to most bacteria, on biliary bacteria are unclear. Here, we investigated the bacterial communities of the biliary tract, duodenum, stomach, and oral cavity from six gallstone patients by using 16S rRNA amplicon sequencing. We found that all observed biliary bacteria were detectable in the upper digestive tract. The biliary microbiota had a comparatively higher similarity with the duodenal microbiota, versus those of the other regions, but with a reduced diversity. Although the majority of identified bacteria were greatly diminished in bile samples, three Enterobacteriaceae genera (Escherichia, Klebsiella, and an unclassified genus) and Pyramidobacter were abundant in bile. Predictive functional analysis indicated enhanced abilities of environmental information processing and cell motility of biliary bacteria. Our study provides evidence for the potential source of biliary bacteria, and illustrates the influence of the biliary system on biliary bacterial communities.

    Biliary adenofibromas (BAFs) are rare, benign biliary cystic tumors with potential for malignant transformation. Of the eleven prior cases of BAF reported in the literature, six showed evidence of malignant transformation. We describe the clinical, imaging and pathology features of two cases of malignant BAF and review the existing literature to raise awareness of this entity and provide additional tools for diagnosing this rare tumor Additionally, we identified a loss of function mutation in the cyclin-dependent kinase inhibitor 2A (CDKN2A) tumor suppressor gene in a malignant caudate lobe BAF, thereby providing potential insight into the molecular pathogenesis of BAF malignant transformation. Although additional cases and longer-term follow-up are needed, our cases suggest that recurrence or metastasis of malignant BAF is not common and that complete surgical resection can be curative.

    Malignant biliary obstruction is commonly caused by gall bladder carcinoma, cholangiocarcinoma and metastatic nodes. Percutaneous interventions play an important role in managing these patients. Biliary drainage, which forms the major bulk of radiological interventions, can be palliative in inoperable patients or pre-operative to improve liver function prior to surgery. Other interventions include cholecystostomy and radiofrequency ablation. We present here the indications, contraindications, technique and complications of the radiological interventions performed in patients with malignant biliary obstruction. PMID:27247718

    Chronic pain after laparoscopic cholecystectomy is related to postoperative pain during the first postoperative week, but it is unknown which components of the early pain response is important. In this prospective study, 100 consecutive patients were examined preoperatively, 1 week postoperatively, and 3, 6, and 12 months postoperatively for pain, psychological factors, and signs of hypersensitivity. Overall pain, incisional pain (somatic pain component), deep abdominal pain (visceral pain component), and shoulder pain (referred pain component) were registered on a 100-mm visual analogue scale during the first postoperative week. Nine patients developed chronic unexplained pain 12 months postoperatively. In a multivariate analysis model, cumulated visceral pain during the first week and number of preoperative biliary pain attacks were identified as independent risk factors for unexplained chronic pain 12 months postoperatively. There were no consistent signs of hypersensitivity in the referred pain area either pre- or postoperatively. There were no significant associations to any other variables examined. The risk of chronic pain after laparoscopic cholecystectomy is relatively low, but significantly related to the visceral pain response during the first postoperative week.

    Kartagener syndrome is an autosomal recessive disorder characterized by primary ciliary dyskinesia accompanied by sinusitis, bronchiectasis, and situs inversus. Synchronous extrahepatic biliary atresia and Kartagener syndrome are very rare. During the preoperative preparation of patients with Kartagener syndrome, special attention is required for the respiratory and cardiovascular system. It is important to provide suitable anaesthetic management to avoid problems because of ciliary dysfunction in the perioperative period. Further, maintaining an effective pain control with regional anaesthetic methods reduces the risk of pulmonary complications. Infants with biliary atresia operated earlier have a higher chance of survival. Hepatic dysfunction and decrease in plasma proteins are important for the kinetics of drugs. In this presentation, the anaesthetic management of patients with synchronous Kartagener syndrome and biliary atresia, both of which are rare diseases, is evaluated. PMID:27366497

    Inflammation of the gallbladder is known to occur in patients with primary sclerosing cholangitis (PSC). However, the histological features of this form of cholecystitis have not been adequately defined. The aim of this study was to compare the inflammatory lesions of PSC-associated cholecystitis with those present in other cholecystopathies. The cases consisted of 11 gallbladders from patients with PSC who underwent liver transplantation. As controls, gallbladders from liver transplant patients with primary biliary cirrhosis (n = 4) and other chronic nonbiliary hepatopathies (n = 8), and 13 cholecystectomies from patients with chronic cholecystitis with (n = 10) and without (n = 3) lithiasis, were studied. The following histological features were tabulated on coded slides: presence, depth of involvement, and distribution of the inflammatory infiltrate, predominant cell type, presence of lymphoid aggregates, epithelial damage, metaplastic changes (pyloric or intestinal), fibrosis, smooth muscle hypertrophy, and presence of Rokitansky-Aschoff sinuses. At variance with the wide range of histological abnormalities present in other forms of chronic cholecystitis, most PSC-related cholecystitis showed a diffuse infiltrate (6 of 11) rich in plasma cells (6 of 11) predominantly confined to the lamina propria (9 of 11). The combination of these three features was present exclusively in PSC (5 of 11 PSC cholecystitis compared with 0 of 25 controls; P = .001). In conclusion, this study suggests that a characteristic form of cholecystitis may develop in patients with PSC.

    We report a case of biliary adenofibroma with an invasive carcinoma in a 71-year-old female who presented with bilateral upper abdominal pain. Imaging revealed a 6.3 cm heterogeneously enhancing mass in the left lateral segment of the liver. Histologically, the adenofibroma showed the characteristic components as previously described of biliary adenofibromata, namely, cystic and tubular structures lined by cuboidal to low columnar biliary type epithelium and a dense fibrous stroma composed of spindled cells. Intimately admixed with the adenofibroma was a distinct tumor composed of malignant clear cells which demonstrated stromal and vascular invasion. Although mitotic figures were inconspicuous, Ki67 was brisk and p53 demonstrated 25–50% positivity. Sections also showed a von Meyenberg complex located adjacent to the tumor. This case expands the understanding of this rare tumor and proves two important assertions from previous case reports. First, the presence of an associated von Meyenberg complex with similar morphology and immunohistochemical staining pattern suggests that biliary adenofibromata and von Meyenberg complexes may share related histogenesis. Second, biliary adenofibromata harbor malignant potential and may show malignant transformation. Furthermore, this case highlights the need for these rare tumors to be followed aggressively, as their biological behavior is poorly understood. PMID:26885426

    Fifteen patients with primary intrahepatic biliary malignancy (cholangiocarcinoma in 13, biliary cystadenocarcinoma in two) were examined by computed tomography (CT). The CT features were classified into three types: (A) a well-defined round cystic mass with internal papillary projections, (B) a localized intrahepatic biliary dilatation without a definite mass lesion, and (C) miscellaneous low-density masses. Intraphepatic biliary dilatation was noted in all cases of Types A and B and half of those of Type C; dilatation of extrahepatic bile ducts occurred in 4/4, 1/3, and 0/8, respectively. CT patterns, such as a well-defined round cystic mass with papillary projections or dilatation of intra- and extrahepatic ducts, give important clues leading to a correct diagnosis of primary intrahepatic biliary malignancy.

    The assessment of echographic features of biliary atresia was conducted in 65 newborn children ageing up to 3 mo. Their characteristic variants were revealed: the absence or reduction in size of gall-bladder, the presence of hyperechogenic triangular formation in V. portae bifurcation (the symptom of "triangular cicatrix"); the thickening of anterior wall of V. portae right branch. The timely and correct establishment of the diagnosis permits a child to survive and serve the hepatic fibrosis prophylaxis. Echohepatography is a sufficiently trustful method of investigation.

    Ultrasonic investigations of the gallbladder in choleretic test were carried out in 186 patients with chronic acalculous cholecystitis (CAC): 47 with intensive, 76 with moderate and 31 with minimal exacerbation, 32 patients in remission and 36 control subjects. As shown by choleretic test, a reduction of latent period and gallbladder contraction duration, a decrease in discharged bile amount, bile discharge velocity, initial and final gallbladder volumes' ration and increased final gallbladder volume occurred in CAC patients. These changes were parallel to inflammation intensity. Three types of gallbladder contraction were revealed in choleretic test: a 3-phase contraction curve with the initial fast evacuation period, relaxation wave (enlarged gallbladder) and slow evacuation period (type 1); a 2-phase curve with fast and slow evacuation (type 2); a monophasic curve with slow evacuation (type 3). In the patients studied type 1 prevailed, while type 3 was not observed in the controls. With increasing inflammation activity in CAC patients a type-1 contraction frequency declined and disappeared in active exacerbation, whereas type 2 and especially type 3 contractions became more frequent.

    Cholescintigraphy with technetium-labeled biliary agents has great value in evaluation of the patient with suspected acute cholecystitis. Visualization of the gall bladder virtually excludes acute cholecystitis and obstruction of the cystic duct. Nonvisualization of the gall bladder, however, is not specific for acute cholecystitis and may also occur in some patients with chronic cholecystitis or pancreatitis. Interpretation of gall bladder nonvisualization, therefore, must be correlated with the clinical presentation. Biliary tract imaging is also useful in evaluation of some focal abnormalities within the liver, neonatal jaundice, detection of bile leaks or bile reflux, and biliary-enteric shunts. The role of technetium-labeled biliary agents in the evaluation of patients with jaundice is less clear. Excretion of tracer into the gut excludes complete biliary tract obstruction, but the test may be nonconclusive at higher serum bilirubin levels. If persistent common bile duct activity is observed with delayed excretion into the gut, the diagnosis of partial obstruction may be made, but this procedure will be inconclusive if the common bile duct is not visualized and/or significant hepatocellular disease is present. Ultrasonography and abdominal CT are the preferred tools for the diagnosis of biliary tract obstruction at present, but newer biliary tract agents which achieve better hepatic extraction and greater bile concentration at high serum bilirubin levels may improve the diagnostic efficacy of cholescintigraphy.

    The diagnosis of biliary strictures can be challenging. Endoscopy has an established role in the diagnosis and therapy of biliary strictures. However, the diagnostic yield from conventional endoscopic retrograde cholangiopancreatography tissue sampling is modest. Improvements in existing technologies as well as the implementation of novel technologies and techniques have the potential to improve the diagnostic performance of endoscopy and expand its therapeutic role. Recent studies have enabled greater clarity about the role of preoperative biliary drainage and the choice of stents in this setting as well as the utility of metal stents in benign and malignant disease.

    Malignant biliary strictures often present late after the window for curative resection has elapsed. In such patients, the goal of therapy is typically focused on palliation. While historically, palliative measures were performed surgically, the advent of endoscopic intervention offers minimally invasive options to provide relief of symptoms, improve quality of life, and in some cases, increase survival of these patients. Some of these therapies, such as endoscopic biliary decompression, have become mainstays of treatment for decades, whereas newer modalities, including radiofrequency ablation, and photodynamic therapy offer additional options for patients with incurable biliary malignancies.

In three, such confirmation was not sought, but all had proven intestinal infestation. One possible and three definite false-positive diagnoses were made. There were no established false-negative diagnoses. The echogenic, nonshadowing images of the worms were seen in the main bile duct and/or gallbladder as single strips (on one occasion with its digestive tract seen as an anechoic "inner tube"), as multiple strips giving a spaghettilike appearance, as coils, or as more amorphous fragments. Follow-up sonograms were obtained in six patients and showed expulsion of the worms by medical treatment.

  7. Autoantigens in primary biliary cirrhosis

    The automimmune liver disease primary biliary cirrhosis (PBC) is characterised by serum autoantibodies directed at mitochondrial and nuclear antigens (seen in most patients and a subset of patients, respectively). The antimitochondrial antibodies (AMA) characteristic of PBC are directed at members of the 2-oxoacid dehydrogenase components of multienzyme complexes; in particular, the E2 and E3 binding protein (E3BP) components of the pyruvate dehydrogenase complex (PDC). The presence of autoantibodies reactive with PDC-E2 and/or E3BP is strongly predictive of the presence of PBC. Therefore, the detection of these antibodies plays a very important role in the diagnosis of PBC. Originally demonstrated using immunofluorescence approaches, AMA can now be detected by the use of commercially available enzyme linked immunosorbent assays (ELISAs). Although the ELISA based approaches have advantages in terms of laboratory practicality, they are slightly less sensitive for the diagnosis of PBC than immunofluorescence (occasional patients with PBC show reactivity with PDC related antigens not present in the antigen preparations available for use with ELISA). Therefore, immunofluorescence should continue to be available as a complementary diagnostic test for use in occasional patients. In a subset of patients with PBC, autoantibodies are directed at increasingly well characterised nuclear antigens. Antinuclear antibody (ANA) positive patients are typically AMA negative. There are no significant differences in disease phenotype between AMA positive and AMA negative groups. At present, the clinical detection of ANA is mostly by Hep2 immunofluorescence, although ELISA kits for individual nuclear antigens are increasingly becoming available.

    OBJECTIVE: The aim of this investigation was to describe the clinical features, diagnosis, pathologic characteristics, and optimal surgical management for patients with extrahepatic biliary cystadenomas. SUMMARY BACKGROUND DATA: Extrahepatic biliary cystadenomas are rare epithelial neoplasms. The clinical features and optimal surgical management for these lesions have not been defined clearly. The usual presenting symptom is jaundice. These lesions should be considered premalignant and necessitate resection. Sporadic case studies have reported instances of recurrence with local excision. To the authors' knowledge, this study represents the largest collected single series of extrahepatic biliary cystadenomas and reviews previously reported cases. METHODS: The authors reviewed and reported their institutional experience from 1950 to 1993 in treating seven patients with extrahepatic biliary cystadenomas as well as 19 previously reported cases in the literature. RESULTS: A strong female predominance (96.3% of patients reviewed) was associated with extrahepatic biliary cystadenomas. Obstructive jaundice was the most common presenting symptom (85%). Abdominal pain occurred in 50% of patients; other symptoms included fever and hemobilia. The most common site of occurrence was the common hepatic duct (32%). Papillary cystadenoma with foci of invasive adenocarcinoma, thus supporting the malignant potential of cystadenomas, occurred in one patient. Local excision from the wall of the bile duct was performed in 18 patients and was associated with 50% recurrence within a mean follow-up of 13 months (range, 4-24 months). No recurrence was reported after formal sleeve resection and bilioenteric reconstruction. CONCLUSIONS: Extrahepatic biliary cystadenomas can become malignant, and in this study, local surgical excision was associated with a 50% local recurrence rate. Sleeve resection with negative histologic resection margins followed by bilioenteric reconstruction, therefore

    Postoperative anastomotic biliary strictures can occur after surgery in bile ducts belonging to transplanted or native (nontransplanted) livers. The majority of postoperative anastomotic strictures encountered by interventional radiologists are most likely in liver transplant recipients due to the large and growing liver transplant recipient population worldwide compared with patients with native livers and biliary enteric anastomoses. They occur after 2.5 to 13% of liver transplantations and they represent at least one-half of biliary strictures encountered after liver transplantation. Anastomotic biliary strictures are considered technical in nature, accentuated by fibrosis and scarring that may be secondary to, if not exacerbated by, graft ischemia. There are numerous variables in the percutaneous transhepatic balloon dilation protocols applied to treat anastomotic biliary strictures. These include (1) types of balloons, (2) how long balloons are inflated, (3) how frequently patients return for additional dilation sessions, and (4) the interval(s) at which they return. No alteration in these variables has proven to improve long-term patency. In addition, new technology such as cutting balloons and stents has not been fully evaluated to determine their effect on long-term patency. The current article describes the overall theme of balloon dilation protocols for the management of anastomotic biliary strictures and discusses possible future management of such strictures.

    Primary Epstein-Barr virus (EBV) infection is almost always a self-limited disease characterized by sore throat, fever, and lymphadenopathy. Hepatic involvement is usually characterized by mild elevations of aminotransferases and resolves spontaneously. Although isolated gallbladder wall thickness has been reported in these patients, acute acalculous cholecystitis is an atypical presentation of primary EBV infection. We presented a young women admitted with a 10-day history of fever, nausea, malaise who had jaundice and right upper quadrant tenderness on the physical examination. Based on diagnostic laboratory tests and abdominal ultrasonographic findings, cholestasis and acute acalculous cholecystitis were diagnosed. Serology performed for EBV revealed the acute EBV infection. Symptoms and clinical course gradually improved with the conservative therapy, and at the 1-month follow-up laboratory findings were normal. We reviewed 16 adult cases with EBV-associated AAC in the literature. Classic symptoms of EBV infection were not predominant and all cases experienced gastrointestinal symptoms. Only one patient underwent surgery and all other patients recovered with conservative therapy. The development of AAC should be kept in mind in patients with cholestatic hepatitis due to EBV infection to avoid unnecessary surgical therapy and overuse of antibiotics. PMID:28194287

    Trichobezoars are an uncommon cause of acute abdominal pain. We present a case of a 12-year-old girl with a history of a trichobezoar who presented to the emergency department with acute abdominal pain. Abdominal sonography was performed which suggested portal venous gas and showed complex peritoneal fluid. Subsequent computed tomography demonstrated both gastric and small bowel bezoars, with a jejunojejunal intussusception, and confirmed portal venous gas and complex ascites. At the time of surgery, there was evidence of intestinal and biliary perforation. Our case illustrates a constellation of complications in association with a long-standing trichobezoar.

    Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease, asymptomatic during a protracted time, characterized by changes in the small-sized bile ducts near portal spaces. The etiology of PBC is undefined, but immunologic and environmental disturbances may contribute to the disease. Infertility is often associated with PBC and cirrhosis, but pregnancy may well occur in women with PBC and without cirrhosis or in some others with compensated cirrhosis. A pluridisciplinary approach including gastroenterologists and obstetricians is recommended. The patient must be closely monitored throughout her pregnancy with maternal and routine antenatal care. Medical treatment requires ursodeoxycholic acid (UDCA). In non-cirrhotic UDCA-treated women with PBC, pregnancy often follows a normal course with vaginal delivery. In cirrhotic patients, UDCA must be continued during pregnancy, esophageal and gastric varices must be evaluated before pregnancy, and endoscopic ligature is recommended for treating large varices. Additionally, beta-blocker therapy may be associated, especially when variceal rupture occurred previously. Elective cesarean section is recommended in patients with large esophageal or gastric varices because of the potentially increased risk of variceal bleeding during maternal expulsive efforts in case of vaginal delivery.

    2015-01-01

    Genome wide association studies (GWAS) have been a significant technological advance in our ability to evaluate the genetic architecture of complex diseases such as Primary Biliary Cirrhosis (PBC). To date, six large-scale studies have been performed which identified 27 non-HLA risk loci associated with PBC. The identified risk variants emphasize important disease concepts; namely, that disturbances in immunoregulatory pathways are important in the pathogenesis of PBC and that such perturbations are shared among a diverse number of autoimmune diseases – suggesting the risk architecture may confer a generalized propensity to autoimmunity not necessarily specific to PBC. Furthermore, the impact of non-HLA risk variants, particularly in genes involved with IL-12 signaling, and ethnic variation in conferring susceptibility to PBC have been highlighted. While GWAS have been a critical stepping-stone in understanding common genetic variation contributing to PBC, limitations pertaining to power, sample availability, and strong linkage disequilibrium across genes have left us with an incomplete understanding of the genetic underpinnings of disease pathogenesis. Future efforts to gain insight into this missing heritability, the genetic variation that contributes to important disease outcomes and the functional consequences of associated variants will be critical if practical clinical translation is to be realized.

    2017-01-01

    Biliary strictures are caused by a heterogeneous group of benign and malignant conditions, each requiring a specific treatment approach. Management of biliary strictures often involves endoscopy either for definite treatment, as a bridge to surgery or for palliative purposes. Endoscopic treatment of various types of biliary strictures is not standardized and there are multiple areas of controversy regarding the best treatment options. These controversies are mainly due to lack of well-designed comparative studies to support a specific therapy. This paper reviews three common areas of controversy in the endoscopic management of biliary strictures. The areas discussed in this editorial include the role of biliary drainage in resectable malignant strictures and whether such drainage should be performed routinely prior to surgery, the best endoscopic palliation for unresectable hilar strictures and whether unilateral or bilateral stenting should be attempted, and the optimal endoscopic management for dominant strictures in patients with primary sclerosing cholangitis. The goal of this editorial is twofold. The first is to review the current literature on management of the aforementioned strictures and offer recommendations based on available evidence. The second goal is to highlight the gaps in our knowledge which in turn can encourage future research on these topics. PMID:28275292

    Unresectable malignant hilar biliary obstruction (MHBO) occurs in various diseases, such as cholangiocarcinoma, gallbladder carcinoma, hepatocellular carcinoma, pancreatic cancer, and lymph node metastasis of the hilum of the liver. The majority of patients with advanced MHBO are not candidates for surgical resection because of the tumor location in the hepatic hilum and adjacent areas, advanced tumor stage, or comorbidities. Therefore, these patients often have a poor prognosis in terms of survival and quality of life. Most of these patients will require non-surgical, palliative biliary drainage. To date, various biliary drainage techniques for unresectable MHBO (UMHBO) have been reported. Of these techniques, endoscopic biliary drainage is currently considered to be the most safe and minimally invasive procedure. However, endoscopic biliary drainage for UMHBO is still not standardized regarding the optimal stent, drainage area, stenting method, and reintervention technique. Recently, towards standardization of this technique for UMHBO, clinical research and trials including randomized controlled trials have been performed. In this article, we reviewed the most important issues regarding endoscopic biliary drainage for UMHBO, focusing on prospective studies. We also described in detail the techniques and future perspectives of endoscopic biliary drainage in patients with UMHBO.

    Although laparoscopic cholecystectomy has become a gold standard in treatment of symptomatic cholelithiasis, it is associated with higher risk of intraoperative lesions and primarily lesions of biliary ducts. In small percentage of cases biliary fistulas occur, most commonly after leakage from cystic duct stump or accessory bile ducts – Luschka’s duct. We report of a patient who had episodes of abdominal pain following routine laparoscopic cholecystectomy for acute calculous gallbladder. Results of conducted diagnostics verify the presence of biliary fistula caused by obstruction of bile pathways by stagnant pus and microcalculi of common bile duct, with development of biloma presumably caused by pressure injection of contrast material during ERCP procedure. Endoscopic sphincterectomy via ERCP enabled healing of formed biliary fistula, whilst continuous percutaneous ultrasound guided drainage of biloma was method of choice in later treatment of our patient. It is important to note that diagnostic evaluation of biliary fistula is very challenging and that timely nonsurgical treatment is of great benefit for patient. PMID:26005280

Imaging by Sonography has identified several parameters which can be of utility in the diagnostic work up. Comparison of Sonography with imaging by Nuclear medicine can bring out the significant differences and also help in appropriate imaging. The battery of Biochemical tests, available currently, enable better understanding of the line-up of investigations in a given child with neonatal cholestasis. Management protocols enable standardized care with optimal outcome.

    We report a series of 15 patients with a postoperative biliary fistula treated by endoscopic sphincterotomy. The exact location of the bile leak was revealed by ERCP in 13 cases (87%): cystic duct remnant in 6 (39%), intrahepatic biliary tree in 4 (26%), and main bile duct in 3 (20%). In all cases a distal obstacle (ie: retained stones, hydatid material) to bile flow was also found in ERCP. Treatment consisted of endoscopic sphincterotomy and subsequent removal of the distal obstacle, and could be completed in 13 (87%) cases. In our experience the treatment of postoperative biliary fistula with a distal obstruction bile flow by endoscopic sphincterotomy is a safe and effective procedure, and should be recommended as the first option in those patients.

    Endoscopic evaluation of indeterminate biliary strictures (IDBSs) has evolved considerably since the development of flexible fiberoptic endoscopes over 50 years ago. Endoscopic retrograde cholangiography pancreatography (ERCP) was introduced nearly a decade later and has since become the mainstay of therapy for relieving obstruction of the biliary tract. However, longstanding methods of ERCP-guided tissue acquisition (i.e., biliary brushings for cytology and intraductal forceps biopsy for histology) have demonstrated disappointing performance characteristics in distinguishing malignant from benign etiologies of IDBSs. The limitations of these methods have thus helped drive the search for novel techniques to enhance the evaluation of IDBSs and thereby improve diagnosis and clinical care. These modalities include, but are not limited to, endoscopic ultrasound, intraductal ultrasound, cholangioscopy, confocal endomicroscopy, and optical coherence tomography. In this review, we discuss established and emerging options in the evaluation of IDBSs. PMID:26675379

    Patient: Female, 24 Final Diagnosis: Gallbladder agenesis Symptoms: — Medication: — Clinical Procedure: — Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Gallbladder agenesis (GA) is an extremely rare anatomic anomaly with a reported incidence of less than 0.5%. It is usually asymptomatic, but can present with features of biliary colic and cholecystitis. We present here a case of GA in a patient with recurrent biliary colic. Case Report: A 24-year-old African American woman presented with recurrent episodes of right upper-quadrant abdominal pain. During her first episode, she was found to have elevated transaminases and clinical features of cholecystitis, but ultrasound did not visualize a gallbladder and she was discharged with a diagnosis of biliary colic. She returned within a week with worsening liver enzymes, severe pain, and vomiting. A hepatobiliary iminodiacetic acid (HIDA) scan was done, which again did not show the gall bladder. On clinical suspicion of acute cholecystitis, she underwent laparoscopic surgery. Intraoperatively, the gall bladder fossa was empty and a diagnosis of gall bladder agenesis was made. She presented a third time with similar complaints and magnetic resonance cholangiopancreatography (MRCP) was done, which showed normal biliary tract anatomy and absent gall bladder. A diagnosis of sphincter of Oddi dysfunction was made and she was discharged on antispasmodics. Conclusions: Diagnosing GA is challenging. The rarity of this entity combined with classic clinical features of cholecystitis and non-visualization of the gall bladder on routine investigation prompts unnecessary surgical intervention. Awareness of this condition, along with use of better imaging modalities like preoperative MRCP, can aide physicians to appropriately manage this uncommon clinical condition. PMID:28365715

    Early surgery for biliary pancreatitis has resulted in a need for an accurate method of gallstone detection in acute pancreatitis. Fifty patients with acute pancreatitis were studied prospectively to assess the diagnostic value of Radionuclide Biliary Scanning (RBS) performed within 72 hours of an attack. To assess the general accuracy of RBS a further 154 patients with suspected acute cholecystitis or biliary colic were similarly studied. There were 34 patients with biliary pancreatitis and 18 (53%) had a positive scan (no gallbladder seen). There were 16 patients with non-biliary pancreatitis and 5 (31%) had a positive scan. All 51 patients with acute cholecystitis had a positive scan, as did 82% of the 51 patients with biliary colic. There were 52 patients with no biliary or pancreatic disease and none of these had a positive scan. RBS is highly accurate in confirming a diagnosis of acute cholecystitis or biliary colic. However, it cannot be relied on to differentiate between biliary and non-biliary pancreatitis and should certainly not be used as the basis for biliary surgery in these patients. PMID:6859781

  6. How Should Biliary Stones be Managed?

    PubMed Central

    2010-01-01

    Minimally invasive therapy is currently invaluable for the treatment of biliary stones. Clinicians should be familiar with the various endoscopic modalities that have been evolving. I reviewed the treatment of biliary stones from the common practice to pioneering procedures, and here I also briefly summarize the results of many related studies. Lithotripsy involves procedures that fragment large stones, and they can be roughly classified into two groups: intracorporeal modalities and extracorporeal shock-wave lithotripsy (ESWL). Intracorporeal modalities are further divided into mechanical lithotripsy (ML), electrohydraulic lithotripsy, and laser lithotripsy. ESWL can break stones by focusing high-pressure shock-wave energy at a designated target point. Balloon dilation after minimal endoscopic sphincterotomy (EST) is effective for retrieving large biliary stones without the use of ML. Peroral cholangioscopy provides direct visualization of the bile duct and permits diagnostic procedures or therapeutic interventions. Biliary stenting below an impacted stone is sometimes worth considering as an alternative treatment in elderly patients. This article focuses on specialized issues such as lithotripsy rather than simple EST with stone removal in order to provide important information on state-of-the-art procedures. PMID:20559517

    Abstract At present, little is known regarding Listeria monocytogenes-associated biliary tract infection, a rare form of listeriosis. In this article, we will study 12 culture-proven cases reported to the French National Reference Center for Listeria from 1996 to 2013 and review the 8 previously published cases. Twenty cases were studied: 17 cholecystitis, 2 cholangitis, and 1 biliary cyst infection. Half were men with a median age of 69 years (32–85). Comorbidities were present in 80%, including cirrhosis, rheumatoid arthritis, and diabetes. Five patients received immunosuppressive therapy, including corticosteroids and anti-tumor necrosis factor biotherapies. Half were afebrile. Blood cultures were positive in 60% (3/5). Gallbladder histological lesions were analyzed in 3 patients and evidenced acute, chronic, or necrotic exacerbation of chronic infection. Genoserogroup of the 12 available strains were IVb (n = 6), IIb (n = 5), and IIa (n = 1). Their survival in the bile was not enhanced when compared with isolates from other listeriosis cases. Adverse outcome was reported in 33% (5/15): 3 deaths, 1 recurrence; 75% of the patients with adverse outcome received inadequate antimicrobial therapy (P = 0.033). Biliary tract listeriosis is a severe infection associated with high mortality in patients not treated with appropriate therapy. This study provides medical relevance to in vitro and animal studies that had shown Listeria monocytogenes ability to survive in bile and induce overt biliary infections. PMID:25319439

    Objectives: This study was designed to audit current practice in percutaneous biliary drainage and stenting in the United Kingdom. Methods: In 2006, the British Society of Interventional Radiology set up the first web-based Biliary Drainage and Stenting Registry (BDSR). This consisted of a series of tick sheets, which were completed online. Data collection included technical and clinical success of the procedures and outcomes at discharge with a separate form for any follow-up visits. Two months before data analysis, all contributors were asked via email to complete any outstanding data. This paper reports on data collected between November 1, 2006 and August 18, 2009. Results: A total of 833 procedures were recorded and were entered by 62 operators from 44 institutions within the United Kingdom. There were 455 men and 378 women with a median age of 69 (range 20-101) years.The majority of procedures were performed by a consultant. Successful drainage of the biliary tree was achieved in 98.7%. Partial or complete relief of symptoms was seen in 65% of patients. Minor complications, predominantly pain (14.3%), were seen in 26% and major complications, predominantly sepsis (3.5%), were seen in 7.9% of patients. Conclusions: These figures provide an essential benchmark for both audit and patient information. Identifying areas of good practice and those that require improvement will ultimately result in better patient care.

    Pancreatic cancer is the fourth leading cause of cancer-related death in the United States and one of the leading causes of cancer mortality in the United States. Due to its aggressive behavior and lack of effective therapies, palliation plays a critical role in the management of the disease. Most patients with pancreatic cancer suffer from severe pain, which adversely predicts prognosis and significantly impacts the quality of life. Therefore pain management plays a central role in palliation. Non-steroidal anti-inflammatory drugs and opioid agents are often first line medications in pain management, but they do not target the underlying pathophysiology of pain and their use is limited by adverse effects and dependence. The proposed mechanisms of pain development in pancreatic cancer include neurogenic inflammation and ductal hypertension which may be targeted by endoscopic therapies. Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) and pancreatic duct stent placement are the two primary endoscopic modalities for palliative management in pancreatic cancer patients with refractory pain.  Other endoscopic treatments such as biliary stent placement and enteral stent placement for biliary and duodenal obstruction may also help palliate pain in addition to their role in decompression. This article reviews the existing evidence for these endoscopic interventions for pain management in pancreatic cancer.

    A 49-year-old woman was admitted to our hospital for back pain with marked thoracic and extremity deformities leading to bed-rest for three years. She was diagnosed with hypophosphatemic osteomalacia based on her symptoms, X-ray and bone scintigram, high serum alkaline phosphatase level, and low serum levels of both phosphorus and 1,25 dihydroxyvitamin D(3) with inhibition of phosphorus reabsorption. Fanconi syndrome with renal tubular acidosis, vitamin D deficiency and primary biliary cirrhosis were related to the pathogenesis of osteomalacia in this case. Several causal diseases may be concomitantly responsible for acceleration of the severity of osteomalacia in this patient.

    Biliary ileus is a rare complication of cholecystolithiasis. The condition occurs predominantly in the elderly with incidence rates of 1-4%, according to the literature data. Most commonly, it develops as a complication of cholelithiasis which remained untreated or was managed conservatively, or as a complication of a gallbladder decubitus necrosis. The condition results in a cholecysto-duodenal fistula. In this case, the cholecystolithiasis is latent or is clinically manifested in a third of the patients. A total of 1560 cholecystectomies (1345 L-CHE and 215 conventional CHE) were performed in our clinic during a five-year period. Biliary ileus was an indication for operation only in two subjects, during the studied period. In the both cases, the diagnosis was established intraoperatively, although upon re-examination of the visualization modalities views (upright native abdominal views, CT scans) the authors concluded that the primary cause of the ileus could have already been identified, based on the above views.

    Our understanding of the natural history of primary biliary cirrhosis (PBC) has been evolving especially following the introduction of ursodeoxycholic acid (UDCA). A clearer understanding of disease pathophysiology and earlier diagnosis with increased prevalence of the disease worldwide has led to increased interest and improved outcomes in patients with PBC. In this article, the authors touch briefly on features of the disease and describe the natural history of PBC prior to and after the introduction of UDCA.

  14. Biliary atresia: From Australia to the zebrafish.

    Davenport, Mark

    2016-02-01

    This review is based upon an invited lecture for the 52nd Annual Meeting of the British Association of Paediatric Surgeons, July 2015. The aetiology of biliary atresia (BA) is at best obscure, but it is probable that a number of causes or pathophysiological mechanisms may be involved leading to the final common phenotype we recognise clinically. By way of illustration, similar conditions to human BA are described, including biliary agenesis, which is the normal state and peculiar final pattern of bile duct development in the jawless fish, the lamprey. Furthermore, there have been remarkable outbreaks in the Australian outback of BA in newborn lambs whose mothers were exposed to and grazed upon a particular plant species (Dysphania glomulifera) during gestation. More recent work using a zebrafish model has isolated a toxic isoflavonoid, now named Biliatresone, thought to be responsible for these outbreaks. Normal development of the bile ducts is reviewed and parallels drawn with two clinical variants thought to definitively have their origins in intrauterine life: Biliary Atresia Splenic Malformation syndrome (BASM) and Cystic Biliary Atresia (CBA). For both variants there is sufficient clinical evidence, including associated anomalies and antenatal detection, respectively, to warrant their aetiological attribution as developmental BA. CMV IgM +ve associated BA is a further variant that appears separate with distinct clinical, histological, and immunohistochemical features. In these it seems possible that this involves perinatal obliteration of a normally formed duct system. Although still circumstantial, this evidence appears convincing enough to perhaps warrant a different treatment strategy. This then still leaves the most common (more than 60% in Western series) variant, now termed Isolated BA, whereby origins can only be alluded to.

    Within the last decade, several mouse models that manifest characteristic features of primary biliary cirrhosis (PBC) with antimitochondrial antibodies (AMAs) and immune-mediated biliary duct pathology have been reported. Here, the authors discuss the current findings on two spontaneous (nonobese diabetic autoimmune biliary disease [NOD.ABD] and dominant negative transforming growth factor-β receptor II [dnTGFβRII]) and two induced (chemical xenobiotics and microbial immunization) models of PBC. These models exhibit the serological, immunological, and histopathological features of human PBC. From these animal models, it is evident that the etiology of PBC is multifactorial and requires both specific genetic predispositions and environmental insults (either xenobiotic chemicals or microbial), which lead to the breaking of tolerance and eventually liver pathology. Human PBC is likely orchestrated by multiple factors and hence no single model can fully mimic the immunopathophysiology of human PBC. Nevertheless, knowledge gained from these models has greatly advanced our understanding of the major immunological pathways as well as the etiology of PBC.

    Endoscopic ultrasound (EUS) is used for diagnosis and evaluation of many diseases of the gastrointestinal (GI) tract. In the past, it was used to guide a cholangiography, but nowadays it emerges as a powerful therapeutic tool in biliary drainage. The aims of this review are: outline the rationale for endoscopic ultrasound-guided biliary drainage (EGBD); detail the procedural technique; evaluate the clinical outcomes and limitations of the method; and provide recommendations for the practicing clinician. In cases of failed endoscopic retrograde cholangiopancreatography (ERCP), patients are usually referred for either percutaneous transhepatic biliary drainage (PTBD) or surgical bypass. Both these procedures have high rates of undesirable complications. EGBD is an attractive alternative to PTBD or surgery when ERCP fails. EGBD can be performed at two locations: transhepatic or extrahepatic, and the stent can be inserted in an antegrade or retrograde fashion. The drainage route can be transluminal, duodenal or transpapillary, which, again, can be antegrade or retrograde [rendezvous (EUS-RV)]. Complications of all techniques combined include pneumoperitoneum, bleeding, bile leak/peritonitis and cholangitis. We recommend EGBD when bile duct access is not possible because of failed cannulation, altered upper GI tract anatomy, gastric outlet obstruction, a distorted ampulla or a periampullary diverticulum, as a minimally invasive alternative to surgery or radiology.

    What should be done next? Is the stricture benign? Is it resectable? Should I place a stent? Which one? These are some of the questions one ponders when dealing with biliary strictures. In resectable cases, ongoing questions remain as to whether the biliary tree should be drained prior to surgery. In palliative cases, the relief of obstruction remains the main goal. Options for palliative therapy include surgical bypass, percutaneous drainage, and stenting or endoscopic stenting (transpapillary or via an endoscopic ultrasound approach). This review gathers scientific foundations behind these interventions. For operable cases, preoperative biliary drainage should not be performed unless there is evidence of cholangitis, there is delay in surgical intervention, or intense jaundice is present. For inoperable cases, transpapillary stenting after sphincterotomy is preferable over percutaneous drainage. The use of plastic stents (PS) has no benefit over Self-Expandable Metallic Stents (SEMS). In case transpapillary drainage is not possible, Endoscopic Ultrasonography- (EUS-) guided drainage is still an option over percutaneous means. There is no significant difference between the types of SEMS and its indication should be individualized. PMID:26981114

    2014-08-01

    Primary biliary cirrhosis (PBC) is an autoimmune liver disease characterized by selective destruction of intrahepatic cholangiocytes. Mechanisms underlying the development and progression of the disease are still controversial and largely undefined. Evidence suggests that PBC results from an articulated immunologic response against an immunodominant mitochondrial autoantigen, the E2 component of the pyruvate dehydrogenase complex (PDC-E2); characteristics of the disease are also the presence of disease-specific antimitochondrial autoantibodies (AMAs) and autoreactive CD4 and CD8 T cells. Recent evidence suggests that cholangiocytes show specific immunobiological features that are responsible for the selective targeting of those cells by the immune system. The immune reaction in PBC selectively targets small sized, intrahepatic bile ducts; although a specific reason for that has not been defined yet, it has been established that the biliary epithelium displays a unique heterogeneity, for which the physiological and pathophysiological features of small and large cholangiocytes significantly differ. In this review article, the authors provide a critical overview of the current evidence on the role of cholangiocytes in the immune-mediated destruction of the biliary tree that characterizes PBC.

    Abstract When confronting a biliary stricture, both benign and malignant etiologies must be carefully considered as a variety of benign biliary strictures can masquerade as hilar cholangiocarcinoma (CCA). Therefore, patients could undergo a major surgery despite the possibility of a benign biliary disease. Approximately 15% to 24% of patients undergoing surgical resection for suspected biliary malignancy will have benign pathology. Eosinophilic cholangitis (EC) is a rare benign disorder of the biliary tract, which can cause obstructive jaundice and can pose a difficult diagnostic task. We present a rare case of a young woman who was referred to our hospital with obstructive painless jaundice due to a biliary stricture at the confluence of the hepatic bile ducts, with a provisional diagnosis of cholangiocarcinoma. Though, during her work up she was found to have EC, an extremely rare benign cause of biliary stricture, which is characterized by a dense eosinophilic infiltration of the biliary tree causing stricturing, fibrosis, and obstruction and which is reversible with short-term high-dose steroids. Despite its rarity, EC should be taken into consideration when imaging modalities demonstrate a biliary stricture, especially if preoperative diagnosis of malignancy cannot be made, in the setting of peripheral eosinophilia and the absence of cardinal symptoms of malignancy.

    Biliary atresia is a rare neonatal disease of unknown etiology, where obstruction of the biliary tree causes severe cholestasis, leading to biliary cirrhosis and death in the first years of life, if the condition is left untreated. Biliary atresia is the most frequent surgical cause of cholestatic jaundice in neonates and should be evoked whenever this clinical sign is associated with pale stools and hepatomegaly. The treatment of biliary atresia is surgical and currently recommended as a sequence of, eventually, two interventions. During the first months of life a hepatoportoenterostomy (a “Kasai,” modifications of which are discussed in this paper) should be performed, in order to restore the biliary flow to the intestine and lessen further damage to the liver. If this fails and/or the disease progresses towards biliary cirrhosis and life-threatening complications, then liver transplantation is indicated, for which biliary atresia represents the most frequent pediatric indication. Of importance, the earlier the Kasai is performed, the later a liver transplantation is usually needed. This warrants a great degree of awareness of biliary atresia, and the implementation of systematic screening for this life-threatening pathology. PMID:23304557

    The primary malignancies of the biliary tract, cholangiocarcinoma and gallbladder cancer, often present at an advanced stage and are marginally sensitive to radiation and chemotherapy. Accumulating evidence indicates that molecularly targeted agents may provide new hope for improving treatment response in biliary tract carcinoma (BTC). In this article, we provide a critical review of the pathogenesis and genetic abnormalities of biliary tract neoplasms, in addition to discussing the current and emerging targeted therapeutics in BTC. Genetic studies of biliary tumors have identified the growth factors and receptors as well as their downstream signaling pathways that control the growth and survival of biliary epithelia. Target-specific monoclonal antibodies and small molecules inhibitors directed against the signaling pathways that drive BTC growth and invasion have been developed. Numerous clinical trials designed to test these agents as either monotherapy or in combination with conventional chemotherapy have been completed or are currently underway. Research focusing on understanding the molecular basis of biliary tumorigenesis will continue to identify for targeted therapy the key mutations that drive growth and invasion of biliary neoplasms. Additional strategies that have emerged for treating this malignant disease include targeting the epigenetic alterations of BTC and immunotherapy. By integrating targeted therapy with molecular profiles of biliary tumor, we hope to provide precision treatment for patients with malignant diseases of the biliary tract.

    Abstract Background: Preoperative biliary drainage (PBD) has been widely used to treat patients with malignant biliary obstruction. However, it is still unclear which method of PBD (endoscopic nasobiliary drainage or endoscopic biliary stenting) is more effective. Thus, we carried out a meta-analysis to compare the safety and efficacy of endoscopic nasobiliary drainage (ENBD) and endoscopic biliary stenting (EBS) in malignant biliary obstruction in terms of preoperative and postoperative complications. Methods: We conducted a literature search of EMBASE databases, PubMed, and the Cochrane Library to identify relevant available articles that were published in English, and we then compared ENBD and EBS in malignant biliary obstruction patients. The preoperative cholangitis rate, the preoperative pancreatitis rate, the incidence of stent dysfunction, the postoperative pancreatic fistula rate, and morbidity were analyzed. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to express the pooled effect on dichotomous variables, and the pooled analyses were performed using RevMan 5.3. Results: Seven published studies (n = 925 patients) were included in this meta-analysis. We determined that patients with malignant biliary obstruction who received ENBD had reductions in the preoperative cholangitis rate (OR = 0.35, 95% CI = 0.25–0.51, P < 0.0001), the postoperative pancreatic fistula rate (OR = 0.38, 95% CI = 0.18–0.82, P = 0.01), the incidence of stent dysfunction (OR = 0.39, 95% CI = 0.28–0.56, P < 0.0001), and morbidity (OR = 0.47, 95% CI = 0.27–0.82, P = 0.008) compared with patients who received EBS. Conclusions: The current meta-analysis suggests that ENBD is better than EBS for malignant biliary obstruction in terms of the preoperative cholangitis rate, the postoperative pancreatic fistula rate, the incidence of stent dysfunction, and morbidity. However, a limitation is that there are no data

    Objective To determine whether preoperative biliary instrumentation and preoperative biliary drainage are associated with increased morbidity and mortality rates after pancreaticoduodenectomy. Summary Background Data Pancreaticoduodenectomy is accompanied by a considerable rate of postoperative complications and potential death. Controversy exists regarding the impact of preoperative biliary instrumentation and preoperative biliary drainage on morbidity and mortality rates after pancreaticoduodenectomy. Methods Two hundred forty consecutive cases of pancreaticoduodenectomy performed between January 1994 and January 1997 were analyzed. Multiple preoperative, intraoperative, and postoperative variables were examined. Pearson chi square analysis or Fisher’s exact test, when appropriate, was used for univariate comparison of all variables. Logistic regression was used for multivariate analysis. Results One hundred seventy-five patients (73%) underwent preoperative biliary instrumentation (endoscopic, percutaneous, or surgical instrumentation). One hundred twenty-six patients (53%) underwent preoperative biliary drainage (endoscopic stents, percutaneous drains/stents, or surgical drainage). The overall postoperative morbidity rate after pancreaticoduodenectomy was 48% (114/240). Infectious complications occurred in 34% (81/240) of patients. Intraabdominal abscess occurred in 14% (33/240) of patients. The postoperative mortality rate was 5% (12/240). Preoperative biliary drainage was determined to be the only statistically significant variable associated with complications (p = 0.025), infectious complications (p = 0.014), intraabdominal abscess (p = 0.022), and postoperative death (p = 0.037). Preoperative biliary instrumentation alone was not associated with complications, infectious complications, intraabdominal abscess, or postoperative death. Conclusions Preoperative biliary drainage, but not preoperative biliary instrumentation alone, is associated with increased

    This pilot study examined symptom relief and quality of life in pediatric patients who received laparoscopic cholecystectomy surgery at our institution for biliary dyskinesia. We used two validated questionnaires: the Child Health Questionnaire (CHQ-PF28), to assess general well-being, and the Gastrointestinal Quality of Life Index (GIQLI), to measure gastrointestinal-related health. After Institutional Review Board approval, all patients under the age of 18 years who underwent laparoscopic cholecystectomy for biliary dyskinesia between November 2006 and May 2010 received mailed questionnaires. Preoperative and postoperative data were retrospectively collected from respondents and included age, race, symptoms, gallbladder ejection fraction values, pathologic findings, and clinical course. Of 89 patients meeting inclusion criteria, 21 responded. Mean age at surgery was 13.08 years (range, 8 to 17 years). The most common preoperative symptoms consisted of nausea (100%), postprandial pain (90.5%), right upper quadrant pain (81.0%), and vomiting (66.7%). Mean long-term follow-up interval was 18.9 months (range, 7 to 40 months; SD 10.37). Patients with long-term symptom relief reported significantly higher GIQLI scores than those with enduring symptoms. Examination of the results from the CHQ-PF28 revealed significantly lower scores than a general U.S. pediatric sample in both the Physical and Psychosocial Summary Measures (P < 0.05). Children experiencing long-term symptom cessation after laparoscopic cholecystectomy reported higher quality of life than those who had incomplete or only short-term relief. However, regardless of the degree of symptom relief, the degree of quality of life experienced by our study sample of patients with biliary dyskinesia is lower than that of a comparable U.S. pediatric sample.

    Abstract. We encapsulate indocyanine green (ICG) in poly[(D,L-lactide-co-glycolide)-co-PEG] diblock (PLGA-PEG) microballoons for real-time fluorescence and hyperspectral imaging of biliary anatomy. ICG-loaded microballoons show superior fluorescence characteristics and slower degradation in comparison with pure ICG. The use of ICG-loaded microballoons in biliary imaging is demonstrated in both biliary-simulating phantoms and an ex vivo tissue model. The biliary-simulating phantoms are prepared by embedding ICG-loaded microballoons in agar gel and imaged by a fluorescence imaging module in a Da Vinci surgical robot. The ex vivo model consists of liver, gallbladder, common bile duct, and part of the duodenum freshly dissected from a domestic swine.

Advanced spectral analysis and image processing algorithms are developed to classify the tissue types and identify the biliary anatomy.

    We encapsulate indocyanine green (ICG) in poly[(D,L-lactide-co-glycolide)-co-PEG] diblock (PLGA-PEG) microballoons for real-time fluorescence and hyperspectral imaging of biliary anatomy. ICG-loaded microballoons show superior fluorescence characteristics and slower degradation in comparison with pure ICG. The use of ICG-loaded microballoons in biliary imaging is demonstrated in both biliary-simulating phantoms and an ex vivo tissue model. The biliary-simulating phantoms are prepared by embedding ICG-loaded microballoons in agar gel and imaged by a fluorescence imaging module in a Da Vinci surgical robot. The ex vivo model consists of liver, gallbladder, common bile duct, and part of the duodenum freshly dissected from a domestic swine. After ICG-loaded microballoons are injected into the gallbladder, the biliary structure is imaged by both hyperspectral and fluorescence imaging modalities. Advanced spectral analysis and image processing algorithms are developed to classify the tissue types and identify the biliary anatomy. While fluorescence imaging provides dynamic information of movement and flow in the surgical region of interest, data from hyperspectral imaging allow for rapid identification of the bile duct and safe exclusion of any contaminant fluorescence from tissue not part of the biliary anatomy. Our experiments demonstrate the technical feasibility of using ICG-loaded microballoons for biliary imaging in cholecystectomy.

    Purpose. To reevaluate the reasons for the occlusion of self-expanding biliary metal stents, on the basis of cholangioscopic findings. Methods. Percutaneous transhepatic cholangioscopy (PTCS) was performed in 15 patients with obstructed biliary Wallstents. The reason for stent insertion was a malignant obstruction in 14 patients; 1 had a benign biliary stricture. Conventional noncovered stents had been inserted in 12 patients; in 3 cases a polyurethane-covered prototype Wallstent had been used. Stent occlusions occurred after 1-55 months. PTCS was performed with a 2.3-mm endoscope through an 11 Fr sheath. Biopsies were taken via the working channel of the endoscope. Results. In all patients with noncovered stents the inner surface of the stent was highly irregular with seaweed-like protrusions (biopsy-proven granulation tissue). Stent incorporation varied from absent (n=1) to subtotal (n=8), but was always incomplete, no matter how long the stent had been in place. Tumor ingrowth was histologically proven in 2 patients. One patient had a large occluding concrement at the proximal end of the stent. In patients with covered stents, the inner surface appeared more regular; however, viable granulation tissue was found inside two stents and tumor ingrowth in one of them. Conclusion. PTCS showed that incorporation of the stent is virtually always incomplete. The factors contributing most to stent occlusion are the buildup of granulation tissue, bile sludge, and tumor overgrowth. Stone formation and tumor ingrowth can also be important, although less common causes of occlusion. A polyurethane stent covering could not prevent tumor ingrowth in one patient and the buildup of viable granulation tissue inside the stent in two further patients; mean stent patency in the three patients with such a stent was 3 months.

    In primary biliary cirrhosis (PBC), the breach of tolerance that leads to active disease involves a disruption in several layers of control, including central tolerance, peripheral anergy, a "liver tolerance effect," and the action of T regulatory cells and their related cytokines. Each of these control mechanisms plays a role in preventing an immune response against self, but all of them act in concert to generate effective protection against autoimmunity without compromising the ability of the host immune system to mount an effective response to pathogens. At the same time, genetic susceptibility, environmental factors, including infection agents and xenobiotics, play important roles in breach of tolerance in the development of PBC.

However, it is clear that more needs to be done to best develop new treatment plans while applying the modalities we have (porto-enterostomy or liver transplantation or both) in a way that will afford the best survival and quality-of-life. This review article will discuss a number of points that are vital to improving care and illustrates the need to further scrutinize treatment decisions.

    Biliary tract cancers, encompassing the gallbladder, extrahepatic bile ducts, and ampulla of Vater, are rare, but highly fatal malignancies. Gallstones, the predominant risk factor for biliary cancers, are linked with hyperlipidemia. As part of a population-based case-control study conducted in Shanghai, China, we examined the associations of serum lipid levels with biliary stones and cancers. We included 460 biliary cancer cases (264 gallbladder, 141 extrahepatic bile duct, and 55 ampulla of Vater), 981 biliary stone cases, and 858 healthy individuals randomly selected from the population. Participants completed an in-person interview and gave overnight fasting blood samples. Participants in the highest quintile of triglycerides (≥ 160 mg/dl) had a 1.4-fold risk of biliary stones (95% CI=1.1-1.9), a 1.9-fold risk of gallbladder cancer (95% CI=1.3-2.8), and a 4.8-fold risk of bile duct cancer (95% CI=2.8-8.1), compared to the reference group (third quintile: 90-124 mg/dl). Participants in the lowest quintile of high-density lipoprotein (HDL) (< 30 mg/dl) had a 4.2-fold risk of biliary stones (95% CI=3.0-6.0), an 11.6-fold risk of gallbladder cancer (95% CI=7.3-18.5), and a 16.8-fold risk of bile duct cancer (95% CI=9.1-30.9), relative to the reference group (third quintile: 40-49 mg/dl). In addition, total cholesterol, low-density lipoprotein (LDL) and apolipoprotein A (apo A) were inversely associated with biliary stones; whereas low levels as well as high levels of total cholesterol, LDL, apo A, and apolipoprotein B (apo B) were associated with excess risks of biliary tract cancers. Our findings support a role for serum lipids in gallstone development and biliary carcinogenesis. PMID:18076041

    Endoscopic ultrasonography-guided biliary drainage (EUS-BD) has been developed as an alternative drainage technique in patients with obstructive jaundice where endoscopic retrograde cholangiopancreatography (ERCP) has failed. Between July 2008 and December 2009, 16 patients (9 men; median age 79 years) with biliopancreatic malignancy, who were candidates for alternative techniques of biliary decompression because ERCP had been unsuccessful, underwent EUS-BD with placement of a transmural or transpapillary partially covered nitinol self-expandable metal stent (SEMS). EUS-assisted cholangiography was successful in all patients, with definition of the relevant anatomy, but biliary drainage was successfully performed in only 12 (75 %) of the 16 patients (9 choledochoduodenostomies with SEMS placement and 3 biliary rendezvous procedures with papillary SEMS placement), with regression of the cholestasis. No major complications and no procedure-related deaths occurred. There was one case of pneumoperitoneum which was managed conservatively. The median follow-up was 170 days. During the follow-up, eight patients of the 12 patients in whom biliary draining was successful died; four are currently alive. None of the patients required endoscopic reintervention. This series demonstrated that EUS-BD with a partially covered SEMS has a high rate of clinical success and low complication rates, and could represent an alternative choice for biliary decompression.

    Clinical description of biliary diseases are slightly over a century old. At the end of last century and beginning of the present one, laws were established and clinical syndromes were described; these are still valid at present. Some modern techniques such as ultrasonography confirmed the importance of the Courvoisier-Terrier law. The first syndromatic description was made by two clinicians from Lyon, Bard and Pic, based on autopsy confirmation of clinical features. This paper analyses those rules and exceptions to Courvoisier-Terrier law. Research carried out by Pablo Marizzi, the Argentine surgeon who introduced operatory cholangiography is also analyzed. By means of this technique he was able to study patients better, transforming biliary surgery into a procedure with scientific basis, thanks to imagenological data. The sphincter described by this author turned out to be a radiological artifact due to the use of oily contrast media. Finally the right and left hydrohepatosis syndromes described by Cattell and Braasch in the 1960s are discussed. In 1971 we pointed out our disagreement over jaundice in left hydrohepatosis.

    Without antibiotherapy, biliary surgery is often followed by infectious complications, possibly serious, indeed life-threatening. Biliary bacteria do are responsible of these complications; mainly E. Coli, Streptococcus faecalis (whose pathogenicity is disputed) and Klebsiella. Bacteroides fragilis and Pseudomonas aeruginosa are restricted to special circumstances. It is often difficult to presee whether bile is infected: some risk factors were emerged by Keighley but their specificity is not excellent; peroperative Gram staining got various results according to the studies. Some prefer to give a systematic antibiotherapy. Preoperative antibiotic treatment should be as short as possible because it does not sterilize bile, but selects resistant bacteria, which induce postoperative complications. It must mainly be aimed at preventing infectious scattering. Surgery is the main part of the treatment. Antibiotic choice has to take into account clinical picture, bacteria (those probably responsible for and their sensibility) and goal of the treatment (prophylactic or curative). Analysis of failures should allow to improve this choice. But only multicenter studies concerning full selected populations of patients are able to prove superiority of one antibiotic to another.

    The complex interplay between immune factors and genetic susceptibility plays an essential role in autoimmune diseases. This is especially true for primary biliary cirrhosis (PBC). PBC is an autoimmune cholestatic liver disease characterized by the destruction of the small intrahepatic bile ducts and the presence of high-titer antimitochondrial antibodies (AMA). Among the currently known risk factors, genetic predisposition remains to be the dominant one. However, it is insufficient to explain the different geographic distributions of PBC and the incomplete concordance in identical twins. This suggests an association between specific environmental factors and the development of PBC. Nevertheless, a clear and rational association of environmental factors with primary biliary cirrhosis has not yet been fully elucidated. Our current understanding of the environmental triggers of PBC is limited to numerous suspected factors involved in its development, such as xenobiotics, electrophilic drugs, infection, and other physical, chemical, and even biological factors. Although the factors leading to the breakdown of immune tolerance in PBC are still largely unknown, related geoepidemiological studies may help us better understand the impact of the environment. In addition, a better understanding of the interplay between environmental factors and PBC is the critical step toward improving our management and control of PBC and autoimmunity in general.

    2013-01-01

    In most cholangiopathies, liver diseases of different etiologies in which the biliary epithelium is the primary target in the pathogenic sequence, the central mechanism involves inflammation. Inflammation, characterized by pleomorphic peribiliary infiltrate containing fibroblasts, macrophages, lymphocytes, as well as endothelial cells and pericytes, is associated to the emergence of “reactive cholangiocytes.” These biliary cells do not possess bile secretory functions, are in contiguity with terminal cholangioles, and are of a less-differentiated phenotype. They have acquired several mesenchymal properties, including motility and ability to secrete a vast number of proinflammatory chemo/cytokines and growth factors along with de novo expression of a rich receptor machinery. These functional properties enable reactive cholangiocytes to establish intimate contacts and to mutually exchange a variety of paracrine signals with the different mesenchymal cell types populating the portal infiltrate. The extensive crosstalk between the epithelial and mesenchymal compartments is the driver of liver repair mechanisms in cholangiopathies, ultimately evolving toward portal fibrosis. Herein, the authors first review the properties of the different cell types involved in their interaction, and then analyze the underlying molecular mechanisms as they relate to liver repair in cholangiopathies.

    Biliary atresia is a rare idiopathic neonatal cholestatic disease characterized by the destruction of both the intra- and extrahepatic biliary ducts. As the disease is progressive all cases will develop portal fibrosis, cirrhosis, and portal hypertension with the sequelae of varices, jaundice, and eventually liver failure requiring a transplant. Survival rates have improved considerably with many females living well in to be childbearing age. Due to the complexity of the disease these pregnancies are considered, high risk. We report the antenatal, intrapartum, and postpartum managements of a pregnancy complicated by biliary atresia. Furthermore, we highlight the importance of a multidisciplinary team approach in optimizing obstetric care for this high risk group. PMID:24459595

    Primary biliary diseases have been associated in several studies with various malignancies. Understanding the risk and optimizing surveillance strategy of these malignancies in this specific subset of patients are an important facet of clinical care. For instance, primary sclerosing cholangitis is associated with an increased risk for cholangiocarcinoma (which is very challenging to diagnose) and when IBD is present for colorectal cancer. On the other hand, primary biliary cirrhosis patients with cirrhosis or not responding to 12 months of ursodeoxycholic acid therapy are at increased risk of hepatocellular carcinoma. In this review we will discuss in detail the risks and optimal surveillance strategies for patients with primary biliary diseases. PMID:27413366

    Internal biliary fistula is a rare complication of a common surgical disease, cholelithiasis. It is seen in 0.74% of all biliary tract surgeries and is thought to be a result of repeated inflammatory periods of the gallbladder. In this report we present a case of incomplete cholecystogastric and cholecystoduodenal fistulae in a single patient missed by ultrasonography and endoscopic retrograde cholangiopancreatography and diagnosed intraoperatively. In the literature there is only one report of an incomplete cholecystogastric fistula. To our knowledge this is the first case of double incomplete internal biliary fistulae. PMID:26904348

    Objective: Gallstone pancreatitis constitutes 40% of all cases with pancreatitis while it constitutes up to 90% of cases with acute pancreatitis. The treatment modality in this patient population is still controversial. In this study, we aimed to compare the results of early and late cholecystectomy for patients with biliary pancreatitis. Material and Methods: Patients treated with a diagnosis of acute biliary pancreatitis in our clinics between January 2000 and December 2011 were retrospectively reviewed. Patients were divided into two groups: Group A, patients who underwent cholecystectomy during the first pancreatitis attack, Group B, patients who underwent an interval cholecystectomy at least 8 weeks after the first pancreatitis episode. The demographic characteristics, clinical symptoms, number of episodes, length of hospital stay, morbidity and mortality data were recorded. All data were evaluated with Statistical Package for the Social Sciences (SPSS) 13.0 for windows and p <0.05 was considered as statistically significant. Results: During the last 12 years, a total of 91 patients with surgical treatment for acute biliary pancreatitis were included into the study. There were 62 female and 29 male patients, with a mean age of 57.9±14.6 years (range: 21–89). A concomitant acute cholecystitis was present in 46.2% of the patients. Group A and B included 48 and 43 patients, respectively. The length of hospital stay was significantly higher in group B (9.4 vs. 6.8 days) (p<0,05). More than half of the patients in Group B were readmitted to the hospital for various reasons. No significant difference was observed between the two groups, one patient died due to heart failure in the postoperative period in group B. Conclusion: In-hospital cholecystectomy after remission of acute pancreatitis is feasible. It will not only result in lower recurrence and complication rates but also shorten length of hospital stay. We recommend performing cholecystectomy during the

    2014-01-01

    The etiology of the autoimmune liver disease primary biliary cirrhosis (PBC) remains largely unresolved, owing in large part to the complexity of interaction between environmental and genetic contributors underlying disease development. Observations of disease clustering, differences in geographical prevalence, and seasonality of diagnosis rates suggest the environmental component to PBC is strong, and epidemiological studies have consistently found cigarette smoking and history of urinary tract infection to be associated with PBC. Current evidence implicates molecular mimicry as a primary mechanism driving loss of tolerance and subsequent autoimmunity in PBC, yet other environmentally influenced disease processes are likely to be involved in pathogenesis. In this review, the authors provide an overview of current findings and touch on potential mechanisms behind the environmental component of PBC. PMID:25057950

    Although ursodeoxycholic acid remains the only approved pharmacotherapy for patients with primary biliary cirrhosis, the better characterization of factors responsible for the poor response to this drug and the emergence of several new putative therapeutic targets now offer significant opportunities to improve the management of patients and our capacity to treat them more efficiently. The availability of novel treatment options, such as fibrates, budesonide, and obeticholic acid, all capable of improving prognostic markers, invites us to reconsider our management and treatment strategies. Early identification of high-risk patients should remain a priority to deliver adjunctive therapies to appropriately selected populations and increase their chances of success. Given the absence of comparative trials, the choice between second-line treatments should be dictated by the biochemical, histological, and expected tolerance profiles. Here the author presents a brief overview of what should be known in this field and proposes a practical approach to facilitate decision making.

    Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease characterized histologically by destruction of intrahepatic bile ducts and serologically by the presence of antimitochondrial antibodies. The incidence and prevalence of PBC are increasing. Fatigue and pruritus are common symptoms in PBC, although the proportion of asymptomatic PBC is increasing due to the widespread use of screening biochemical tests and antimitochondrial antibody assays. PBC may eventually lead to cirrhosis and its consequent complications. In the 1980s, PBC was the leading indication for liver transplantation. Ursodeoxycholic acid is the only US FDA-approved therapeutic agent for PBC. Clinical trials have shown that the use of ursodeoxycholic acid in PBC results in reduction of liver biochemistries, a delay in histological progression, a delay in the development of varices and improvement in survival without liver transplantation.

    The association of pulmonary fibrosis and primary biliary cirrhosis (PBC) remains controversial. To determine the frequency of pulmonary fibrosis in PBC, a carefully selected series of 14 PBC patients, seven patients with Sicca complex, and 14 control subjects have been studied. Seven of the 14 patients with PBC had Sjögren's syndrome, four of whom had some clinical evidence of pulmonary disease. Evaluation of ventilatory capacity, gas transfer factor, arterial blood gases, and lung mechanics were performed. Gas transfer was reduced in patients with PBC associated with Sjögen's syndrome and in patients with the Sicca complex. These results suggest that the respiratory, clinical, ad functional abnormalities found in PBC are related to the presence of an associated Sjögen's syndrome. PMID:7281088

    A patient with primary biliary cirrhosis (PBC) who developed idiopathic myelofibrosis (IM) is reported. The initial diagnosis of PBC was established by liver biopsy, performed after a 2-month history of constitutional symptoms associated with abnormalities of the serum liver enzymes, with typical serum immunological markers being found. Although a favorable response of PBC to prednisone was observed, one and a half year later the patient developed anemia with anisocytosis and poikilocytosis, tear-drop cells, and leukoerythroblastic picture, and IM was diagnosed by bone marrow biopsy. A few months later, a rapid worsening of the patient's clinical condition was noted, with an increase in the constitutional symptoms and need for frequent packed RBC transfusions, and she finally died from an infectious complication. This case represents a new association of IM with an autoimmune disease, supporting the hypothesis of a possible immune basis of IM in some cases.

    Primary biliary cirrhosis is a classical autoimmune liver disease and is present in around 1 in 1,000 women over the age of 40. It has a number of diagnostic characteristics consistent with autoimmune liver injury, in particular, the high specificity of circulating anti-mitochondrial antibodies. Histologically, the disease is reflected as a granulomatous lymphocytic cholangitis that consequently leads to small bile duct loss and cholestasis. Progressive disease is characterised by the development of a biliary cirrhosis, with end-stage features of liver disease ultimately impacting patient outcomes. Studies support a combination of environmental and genetic risk factors that coalesce to lead to loss of immunological tolerance and persistent biliary inflammation. Significant advances have occurred recently in understanding the genetic risk factors for disease, as well as utilising human and murine studies to characterise the nature of the biliary injury and cholestatic response.

    Intrahepatic cholangiocarcinoma (ICC) is a treatment refractory malignancy with a high mortality and an increasing incidence worldwide. Recent studies have observed that activation of Notch and AKT signalling within mature hepatocytes is able to induce the formation of tumours displaying biliary lineage markers, thereby raising the suggestion that it is hepatocytes, rather than cholangiocytes or hepatic progenitor cells that represent the cell of origin of this tumour. Here we utilise a cholangiocyte-lineage tracing system to target p53 loss to biliary epithelia and observe the appearance of labelled biliary lineage tumours in response to chronic injury. Consequent to this, up-regulation of native functional Notch signalling is observed to occur spontaneously within cholangiocytes and hepatocytes in this model as well as in human ICC. These data prove that in the context of chronic inflammation and p53 loss, frequent occurrences in human disease, biliary epithelia are a target of transformation and an origin of ICC. PMID:24310400

    2001-05-01

    The most frequent primary cancers causing malignant obstructive jaundice were pancreatic cancer (57%), hilar biliary cancer (19% including metastatic disease), nonhilar biliary cancer (14%) and papillary cancer (10%). Endoscopic stenting has widely replaced palliative surgery for malignant biliary obstruction because of its lower risk and cost. Self-expandable metal stents are the preferred mode of palliation for hilar malignancies. Plastic stents have a major role in benign biliary strictures. Major complications and disadvantages associated with metallic stents include high cost, cholangitis. malposition, migration, unextractability, and breakage of the stents, pancreatitis and stent dysfunction. Dysfunction due to tumor ingrowth can be relieved by thermal methods (argon plasma coagulator therapy). We present a concise review of the efficacy of metallic stents for palliation of malignant strictures.

    2016-01-01

    Biliary complications are common after living donor liver transplant (LDLT) although with advancements in surgical understanding and techniques, the incidence is decreasing. Biliary strictures are more common than leaks. Endoscopic retrograde cholangiopancreatography (ERCP) is the first line modality of treatment of post LDLT biliary strictures with a technical success rate of 75%-80%. Most of ERCP failures are successfully treated by percutaneous transhepatic biliary drainage (PTBD) and rendezvous technique. A minority of patients may require surgical correction. ERCP for these strictures is technically more challenging than routine as well post deceased donor strictures. Biliary strictures may increase the morbidity of a liver transplant recipient, but the mortality is similar to those with or without strictures. Post transplant strictures are short segment and soft, requiring only a few session of ERCP before complete dilatation. Long-term outcome of patients with biliary stricture is similar to those without stricture. With the introduction of new generation cholangioscopes, ERCP success rate may increase, obviating the need for PTBD and surgery in these patients. PMID:27057304

  18. Imaging of malignancies of the biliary tract- an update

    PubMed Central

    2014-01-01

    Malignancies of the biliary tract include cholangiocarcinoma, gallbladder cancers and carcinoma of the ampulla of Vater. Biliary tract adenocarcinomas are the second most common primary hepatobiliary cancer. Due to their slow growing nature, non-specific and late symptomatology, these malignancies are often diagnosed in advanced stages with poor prognosis. Apart from incidental discovery of gall bladder carcinoma upon cholecystectomy, early stage biliary tract cancers are now detected with computed tomography (CT) and magnetic resonance imaging (MRI) with magnetic resonance cholangiopancreatography (MRCP). Accurate characterization and staging of these indolent cancers will determine outcome as majority of the patients’ are inoperable at the time of presentation. Ultrasound is useful for initial evaluation of the biliary tract and gallbladder masses and in determining the next suitable modality for further evaluation. Multimodality imaging plays an integral role in the management of the biliary tract malignancies. The imaging techniques most useful are MRI with MRCP, endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound (EUS) and positron emission tomography (PET). In this review we will discuss epidemiology and the role of imaging in detection, characterization and management of the biliary tract malignancies under the three broad categories of cholangiocarcinomas (intra- and extrahepatic), gallbladder cancers and ampullary carcinomas.

    The role of biliary excretion of iron and ferritin in iron overload was studied and evaluated. Ten patients with idiopathic hemochromatosis and two groups of controls (14 gallstone patients and 16 healthy subjects) were included. Liver tissue (obtained by percutaneous or operative biopsy) was investigated with light microscopy and transmission electron microscopy in combination with x-ray microanalysis. Fasting bile samples were obtained through duodenal aspiration or at cholecystectomy. Iron was determined in liver tissue and bile using atomic absorption spectroscopy, and ferritin was determined in serum and bile with a radioimmunoassay technique. All patients with hemochromatosis had iron-positive staining as seen in light microscopy. Electron microscopy showed iron-containing proteins in the lysosomes and cytosol of liver parenchymal cells, and this observation was supported by x-ray microanalysis. Hepatic iron concentration was increased about eightfold in the patients with hemochromatosis (p less than 0.001). Biliary iron concentration, expressed per millimole of bile acid, was increased about twofold (p less than 0.05) and biliary ferritin concentration about fivefold (p less than 0.001) in hemochromatosis. Four of the patients with hemochromatosis were reexamined after completed treatment with venesection; this resulted in normalized biliary concentrations of iron and ferritin. We conclude that biliary secretion of ferritin occurs in humans and that both iron and ferritin excretion are enhanced in hepatic iron overload. The apparently limited capacity of biliary iron excretion may be of importance for the hepatic iron accumulation in hemochromatosis.

  20. Diagnosis and Treatment of Biliary Fistulas in the Laparoscopic Era

    2016-01-01

    Biliary fistulas are rare complications of gallstone. They can affect either the biliary or the gastrointestinal tract and are usually classified as primary or secondary. The primary fistulas are related to the biliary lithiasis, while the secondary ones are related to surgical complications. Laparoscopic surgery is a therapeutic option for the treatment of primary biliary fistulas. However, it could be the first responsible for the development of secondary biliary fistulas. An accurate preoperative diagnosis together with an experienced surgeon on the hepatobiliary surgery is necessary to deal with biliary fistulas. Cholecystectomy with a choledocoplasty is the most frequent treatment of primary fistulas, whereas the bile duct drainage or the endoscopic stenting is the best choice in case of minor iatrogenic bile duct injuries. Roux-en-Y hepaticojejunostomy is the extreme therapeutic option for both conditions. The sepsis, the level of the bile duct damage, and the involvement of the gastrointestinal tract increase the complexity of the operation and affect early and late results. PMID:26819608

    2016-01-01

    Background and Objectives: Laparoscopic transcystic common bile duct exploration (LTCBDE) is a complex procedure requiring expertise in laparoscopic and choledochoscopic skills. The purpose of this study was to investigate the safety and feasibility of treating biliary calculi through laparoscopic transcystic exploration of the CBD via an ultrathin choledochoscope combined with dual-frequency laser lithotripsy. Methods: From August 2011 through September 2014, 89 patients at our hospital were treated for cholecystolithiasis with biliary calculi. Patients underwent laparoscopic cholecystectomy and exploration of the CBD via the cystic duct and the choledochoscope instrument channel. A dual-band, dual-pulse laser lithotripsy system was used to destroy the calculi. Two intermittent laser emissions (intensity, 0.12 J; pulse width 1.2 μs; and pulse frequency, 10 Hz) were applied during each contact with the calculi. The stones were washed out by water injection or removed by a stone-retrieval basket. Results: Biliary calculi were removed in 1 treatment in all 89 patients. No biliary tract injury or bile leakage was observed. Follow-up examination with type-B ultrasonography or magnetic resonance cholangiopancreatography 3 months after surgery revealed no instances of retained-calculi–related biliary tract stenosis. Conclusion: The combined use of laparoscopic transcystic CBD exploration by ultrathin choledochoscopy and dual-frequency laser lithotripsy offers an accurate, convenient, safe, effective method of treating biliary calculi.

    We have studied 22 consecutive patients referred for investigation of severe chronic right upper quadrant pain. The majority were women whose symptoms had been present for many years. All had undergone repeated investigations of the pancreatico-biliary, gastro-intestinal, urinary, and even gynaecological systems without a satisfactory diagnosis. Most had undergone at least one abdominal operation in an unsuccessful attempt to cure their pain. In 21 of 22 patients the customary pain was completely and reproducibly mimicked by balloon distension of the small or large intestine in at least one site. The trigger sites were jejunum (15), ileum (12), right colon (nine), and duodenum (six). In 12 more than one trigger site was found. Close questioning revealed features of the irritable bowel syndrome in the majority and depression in many though the symptoms were not spontaneously volunteered. Reproduction of pain has provided a convincing demonstration to this difficult group of patients that they have a sensitive gut and allows appropriate management.

    Adenocarcinoma of the gallbladder and cholangiocarcinoma account for 4% and 3%, respectively, of all gastrointestinal cancers. Advanced biliary tract carcinoma has a very poor prognosis with all current available modalities of treatment. In this pilot open-label study, the authors investigated the efficacy and safety of a combination of dimethyl sulfoxide-sodium bicarbonate (DMSO-SB) infusion and S-adenosyl-L-methionine (ademetionine) oral supplementation as palliative pharmacotherapy in nine patients with advanced nonresectable biliary tract carcinomas (ABTCs). Patients with evidence of biliary obstruction with a total serum bilirubin ≤300 μmol/L were allowed to join the study. The results of this 6-month study and follow-up of all nine patients with ABTC indicated that the investigated combination treatment improved pain control, blood biochemical parameters, and quality of life for the patients. Moreover, this method of treatment has led to a 6-month progression-free survival for all investigated patients. The treatment was well tolerated for all patients without major adverse reactions. Given that ABTC is a highly fatal malignancy with poor response to chemotherapy and targeted drugs, the authors consider that the combination of DMSO-SB and ademetionine deserves further research and application as a palliative care and survival-enhancing treatment for this group of patients.

    Background and study Aims: Selective biliary cannulation is unsuccessful in 5 % to 10 % of patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) for malignant distal biliary obstruction (MDBO). Percutaneous biliary drainage (PBD) has been the gold standard, but endoscopic ultrasound guided rendezvous (EUSr) have been increasingly used for biliary decompression in this patient population. Our aim was to compare the initial success rate, long-term efficacy, and safety of PBD and EUSr in relieving MDBO after failed ERC Patients and methods: A retrospective study involving 50 consecutive patients who had an initial failed ERCP for MDBO. Twenty-five patients undergoing EUSr between 2008 – 2014 were compared to 25 patients who underwent PBD immediately prior to the introduction of EUSr at our center (2002 – 2008). Comparisons were made between the two groups with regard to technical success, duration of hospital stay and adverse event rates after biliary decompression. Results: The mean age at presentation was 66.5 (± 12.6 years), 28 patients (54.9 %) were female. The etiology of MDBO was pancreaticobiliary malignancy in 44 (88 %) and metastatic disease in 6 (12 %) cases. Biliary drainage was technically successful by EUSr in 19 (76 %) cases and by PBD in 25 (100 %) (P = 0.002). Median length of hospital stay after initial drainage was 1 day in the EUSr group vs 5 days in PBD group (P = 0.02). Repeat biliary intervention was required for 4 patients in the EUSr group and 15 in the PBD group (P = 0.001). Conclusions: Initial technical success with EUSr was significantly lower than with PBD, however when EUSr was successful, patients had a significantly shorter post-procedure hospital stay and required fewer follow-up biliary interventions.

  6. Foetal pain?

    PubMed

    Derbyshire, Stuart W G

    2010-10-01

    The majority of commentary on foetal pain has looked at the maturation of neural pathways to decide a lower age limit for foetal pain. This approach is sensible because there must be a minimal necessary neural development that makes pain possible. Very broadly, it is generally agreed that the minimal necessary neural pathways for pain are in place by 24 weeks gestation. Arguments remain, however, as to the possibility of foetal pain before or after 24 weeks. Some argue that the foetus can feel pain earlier than 24 weeks because pain can be supported by subcortical structures. Others argue that the foetus cannot feel pain at any stage because it is maintained in a state of sedation in the womb and lacks further neural and conceptual development necessary for pain. Much of this argument rests on the definition of terms such as 'wakefulness' and 'pain'. If a behavioural and neural reaction to a noxious stimulus is considered sufficient for pain, then pain is possible from 24 weeks and probably much earlier. If a conceptual subjectivity is considered necessary for pain, however, then pain is not possible at any gestational age. Regardless of how pain is defined, it is clear that pain for conceptual beings is qualitatively different than pain for non-conceptual beings. It is therefore a mistake to draw an equivalence between foetal pain and pain in the older infant or adult.

    AIM To investigate endoscopic therapy efficacy for refractory benign biliary strictures (BBS) with multiple biliary stenting and clarify predictors. METHODS Ten consecutive patients with stones in the pancreatic head and BBS due to chronic pancreatitis who underwent endoscopic therapy were evaluated. Endoscopic insertion of a single stent failed in all patients. We used plastic stents (7F, 8.5F, and 10F) and increased stents at intervals of 2 or 3 mo. Stents were removed approximately 1 year after initial stenting. BBS and common bile duct (CBD) diameter were evaluated using cholangiography. Patients were followed for ≥ 6 mo after therapy, interviewed for cholestasis symptoms, and underwent liver function testing every visit. Patients with complete and incomplete stricture dilations were compared. RESULTS Endoscopic therapy was completed in 8 (80%) patients, whereas 2 (20%) patients could not continue therapy because of severe acute cholangitis and abdominal abscess, respectively. The mean number of stents was 4.1 ± 1.2. In two (20%) patients, BBS did not improve; thus, a biliary stent was inserted. BBS improved in six (60%) patients. CBD diameter improved more significantly in the complete group than in the incomplete group (6.1 ± 1.8 mm vs 13.7 ± 2.2 mm, respectively, P = 0.010). Stricture length was significantly associated with complete stricture dilation (complete group; 20.5 ± 3.0 mm, incomplete group; 29.0 ± 5.1 mm, P = 0.011). Acute cholangitis did not recur during the mean follow-up period of 20.6 ± 7.3 mo. CONCLUSION Sequential endoscopic insertion of multiple stents is effective for refractory BBS caused by chronic calcifying pancreatitis. BBS length calculation can improve patient selection procedure for therapy. PMID:28101303

    Background—Endotoxaemia is implicated in the pathophysiology of obstructive jaundice. The EndoCab enzyme linked immunosorbent assay (ELISA) is a novel assay which measures endogenous antibody (IgG) to the inner core region of circulating endotoxins (ACGA). 
Aims—To investigate the significance of endotoxaemia in biliary obstruction using the EndoCab assay and assess the specificity of the humoral response to endotoxin compared with an exogenous antigenic challenge (tetanus toxoid, TT). 
Methods—Three groups of adult male Wistar rats were studied: no operation, sham operation, and bile duct ligation for 21 days (BDL). In the second study, rats rats received prior immunisation with TT. 
Results—In the preliminary experiment, plasma ACGA was significantly increased in the BDL group (306.6 (18.3)% versus 119.9(6.7)% and 105.2 (4.6)% in the sham and no operation groups, respectively; p<0.001). Although the mean endotoxin concentration in the BDL group was greater than that in the control groups this was not significant. There was a strong positive correlation between ACGA and endotoxin concentrations (p=0.0021). In the second study mean ACGA after 21 days of BDL was significantly elevated (267.1 (31.2)% versus 101.6 (21.2)% at baseline, p<0.0001). ACGA was unaffected in the other two groups. TT antibody concentrations fell in all three groups; only in the BDL group was the fall significant (97.6(5.3)% versus 78.8 (4.2)% at baseline, p<0.05). 
Conclusions—The specific rise in ACGA supports the hypothesis that endotoxin has an integral role in the pathophysiology of obstructive jaundice. The production of anticore glycolipid antibodies specifically reflects systemic endotoxaemia in this model. The EndoCab assay provides a novel, sensitive, and specific method for endotoxin detection.

This article briefly reviews the available literature on the vascular supply of the biliary tract in the light of biliary changes induced by portal cavernoma. Literature pertaining to venous drainage of the biliary tract is scanty whereas more attention was focused on the arterial supply probably because of its significant surgical implications in liver transplantation and development of ischemic changes and strictures in the bile duct due to vasculobiliary injuries. Since the general pattern of arterial supply and venous drainage of the bile ducts is quite similar, the arterial supply of the biliary tract is also reviewed. Fine branches from the posterior superior pancreaticoduodenal, retroportal, gastroduodenal, hepatic and cystic arteries form two plexuses to supply the bile ducts. The paracholedochal plexus, as right and left marginal arteries, run along the margins of the bile duct and the reticular epicholedochal plexus lie on the surface. The retropancreatic, hilar and intrahepatic parts of biliary tract has copious supply, but the supraduodenal bile duct has the poorest vascularization and hence susceptible to ischemic changes. Two venous plexuses drain the biliary tract. A fine reticular epicholedochal venous plexus on the wall of the bile duct drains into the paracholedochal venous plexus (also called as marginal veins or parabiliary venous system) which in turn is connected to the posterior superior pancreaticoduodenal vein, gastrocolic trunk, right gastric vein, superior mesenteric vein inferiorly and intrahepatic portal vein branches superiorly. These pericholedochal venous plexuses constitute the porto-portal collaterals and dilate in portomesenteric venous obstruction forming the portal cavernoma. PMID:25755590

    The timing of biliary surgery remains controversial in patients with acute pancreatitis associated with cholelithiasis. Eighty hospital admissions for acute pancreatitis, occurring in 74 patients with cholelithiasis, have therefore been reviewed. Among 22 patients who underwent abdominal surgery during the first week of treatment, there were five deaths (23%) and four patients (18%) who required more than seven days of intensive care. Fifty-eight episodes of pancreatitis were managed nonoperatively during the first week of treatment, with no deaths, although six (10%) required more than seven days of intensive care. Biliary surgery was undertaken later during the same admission in 37 patients, with no deaths. Twenty-one patients were discharged without biliary operation, but seven (33%) developed further pancreatitis. Previously reported prognostic signs were used to divide pancreatitis into 57 “mild” episodes (1.8% mortality) and 23 “severe” episodes (17% mortality). Early (day 0-7) definitive biliary surgery was undertaken in 11 patients with “mild” pancreatitis, with one death (9%), and in six patients with “severe” pancreatitis, with four deaths (67%). In three recent patients with “severe” pancreatitis, early biliary surgery was limited to cholecystostomy, with no deaths. These findings suggest that although early correction of associated biliary disease may be undertaken safely in many patients with “mild” acute pancreatitis, early definitive surgery is hazardous in “severe” pancreatitis and should, if possible, be deferred until pancreatitis has subsided. In most patients biliary surgery should precede hospital discharge. PMID:443917

    Acute pancreatitis (AP) is a common disease that is associated with significant morbidity and considerable mortality. In this article, developments relating to this disease that were presented in DDW 2014 are reviewed. Pancreatic steatosis could be a cause of recurrent AP. Patients with DM have an increased incidence of AP and pancreatic cancer. The use of anti-TNF drugs in inflammatory bowel disease may protect against the occurrence of AP. The presence of pancreas divisum protects against acute biliary pancreatitis. The PANCODE system for describing local complications of AP has good interobserver agreement, when the new definitions of the revised Atlanta classification are applied. The use of prophylactic antibiotics in early-stage AP predisposes the development of intra-abdominal fungal infections. Fluid sequestration in AP is linked with young age, alcoholism and indicators of systemic inflammatory response syndrome. The most common cause of mortality in AP is early onset of multiple organ failure, not pancreatic necrosis infection. Patients with AP and vitamin D deficiency could benefit from taking vitamin D supplements. Moderate fluid administration in emergencies (500-1000 mL) could be associated with better AP development.

    2009-02-01

    There has been a rapid growth in our understanding of the molecular bases of primary biliary cirrhosis (PBC). These efforts were initiated when the immunodominant mitochondrial autoantigen was cloned and sequenced. Using the recombinant cloned antigen as a tool, research has focused on the effector mechanisms of disease and the uniqueness of the primary target tissue, the intrahepatic bile ducts. Most recently, there have been experimental data suggesting that innate immunity changes may be critical to the initiation and perpetuation of the autoimmune injury, as in the case of the enhanced response of monocytes and memory B cells to infectious stimulation and environmental mimics. These observations are important as they help fill in the many gaps which remain on the most difficult subject of autoimmunity, etiology. Indeed, based on the available data, several experimental models of PBC have been developed. These models illustrate and suggest that PBC can be initiated by several mechanisms, all of which lead to loss of tolerance to the mitochondrial antigens. However, once this adaptive response develops, it appears that much of the subsequent pathology is exacerbated by innate responses. We suggest that future therapeutic efforts in PBC will depend heavily on understanding the nature of this innate immune responses and methodology to blunt their cytotoxicity.

    We analyzed the records of 22 patients with cancers of extrahepatic biliary passages (EHBP) to understand their natural histories and patterns of failure and to evaluate the effectiveness of various treatments. None of the preoperative investigations consistently defined the entire extent of tumor. Percutaneous transhepatic cholangiography (PTHC) was the most helpful (100%) in accurately defining the site of ductal obstruction. Computed tomography was helpful in diagnosing liver metastases in 53% and primary tumor mass in 23% of patients. The most common sites of tumor failure or persistence were: liver (67%), tumor bed (56%), peritoneum (22%), porta hepatis and lymph nodes (17%). The median survival for the entire group was 6.8 months. Surgery plays an important role in managing these tumors and in defining tumor extent for subsequent adjuvant irradiation. Patients receiving radiation doses greater than or equal to 70 TDF had a longer median survival (11 months) than patients receiving less than 70 TDF (4.4 months). All three patients, who were alive and free of disease greater than 1 year, received radiation doses greater than or equal to 70 TDF. From our data, it is difficult to comment on the effectiveness of chemotherapy. We have made suggestions regarding radiation volume and doses to various structures. The need for entering these patients into multi-institutional clinical trials is stressed.

Predicting outcome is of key importance in clinical management and an essential requirement for patients counselling and timing of diagnostic and therapeutic interventions. The following factors are associated with progressive disease and worse outcome: young age at diagnosis, male gender, histological presence of cirrhosis, accelerated marked uctopenia in relation to the amount of fibrosis, high serum bilirubin, low serum albumin levels, high serum alkaline phosphatase levels, esophageal varices, hepatocellular carcinoma (HCC) and lack of biochemical response to ursodeoxycholic acid (UDCA). The prognostic significance of symptoms at diagnosis is uncertain. UDCA therapy and liver transplantation have a significant beneficial effect on the outcome of the disease. The Mayo risk score in PBC can be used for estimating individual prognosis. The Newcastle Varices in PBC Score may be a useful clinical tool to predict the risk for development of esophageal varices. Male gender, cirrhosis and non-response to UDCA therapy in particular, are risk factors for development of HCC.

    Primary biliary cirrhosis (PBC) is a chronic liver disease characterized by the immune mediated destruction of small intrahepatic bile duct epithelial cells leading to cholestasis and cirrhosis. The autoimmune basis of PBC is supported by the highly specific anti-mitochondrial antibodies (AMAs) and autoreactive T cells, the former being the basis for diagnosis in the vast majority of cases. Although a rare disease, the incidence rates of PBC have been increasing, possibly due to increased testing and diagnosis as opposed to a true increase in disease incidence. Presently, most cases are asymptomatic and only suspected based upon routine liver tests. Those with symptoms typically complain of pruritus and fatigue. The diagnosis of PBC is based on the presence of at least 2 of 3 key criteria including a persistently elevated serum alkaline phosphatase, the presence of serum AMAs, and liver histology consistent with PBC. Anti-nuclear antibodies specific to PBC are useful in cases in which AMAs are not detected and may indicate a more aggressive course. Ursodeoxycholic acid is the only proven therapy for PBC and in most cases can delay or prevent disease progression. However, a subgroup of patients does not adequately respond to ursodeoxycholic acid and for whom new therapies are needed.

    Primary biliary cirrhosis (PBC) is a chronic non-suppurative destructive intrahepatic cholangitis leading to cirrhosis after a protractive non cirrhotic stage. The etiology and pathogenesis are largely unknown and autoimmne mechanisms have been implicated to explain the pathological lesions. Many epitopes and autoantigens have been reported as crucial in the pathophysiology of the disease and T and B cells abnormalities have been described, the exact pathways leading to the destruction of small intrahepatic ductules are mostly speculative. In this review we examined the various epidemiologal and geoepidemiological data as well as the complex pathogenetic aspects of this disease, focusing on recent in vivo and in vitro studies in this field. Initiation and progression of PBC is believed to be a multifactorial process with strong infuences from the patient’s genetic background and by various environmental factors. The role of innate and adaptive immunity, including cytokines, chemokines, macrophages and the involvement of apoptosis and reactive oxygen species are outlined in detailed. The current pathogenetic aspects are presented and a novel pathogenetic theory unifying the accumulated clinical information with in vitro and in vivo data is formulated. A review of clinical manifestations and immunological and pathological diagnosis was presented. Treatment modalities, including the multiple mechanisms of action of ursodeoxycholate were finally discussed. PMID:26261733

    ABSTRACT Objectives: Biliary atresia (BA) is a progressive fibroinflammatory cholangiopathy affecting the bile ducts of neonates. Although BA is the leading indication for pediatric liver transplantation, the etiology remains elusive. Adducin 3 (ADD3) and X-prolyl aminopeptidase 1 (XPNPEP1) are 2 genes previously identified in genome-wide association studies as potential BA susceptibility genes. Using zebrafish, we investigated the importance of ADD3 and XPNPEP1 in functional studies. Methods: To determine whether loss of either gene leads to biliary defects, we performed morpholino antisense oligonucleotide (MO) knockdown studies targeting add3a and xpnpep1 in zebrafish. Individuals were assessed for decreases in biliary function and the presence of biliary defects. Quantitative polymerase chain reaction was performed on pooled 5 days postfertilization larvae to assess variations in transcriptional expression of genes of interest. Results: Although both xpnpep1 and add3a are expressed in the developing zebrafish liver, only knockdown of add3a produced intrahepatic defects and decreased biliary function. Similar results were observed in homozygous add3a mutants. MO-mediated knockdown of add3a also showed higher mRNA expression of hedgehog (Hh) targets. Inhibition of Hh signaling rescued biliary defects caused by add3a knockdown. Combined knockdown of add3a and glypican-1 (gpc1), another mediator of Hh activity that is also a BA susceptibility gene, resulted in more severe biliary defects than knockdown of either alone. Conclusions: Our results support previous studies identifying ADD3 as a putative genetic risk factor for BA susceptibility. Our results also provide evidence that add3a may be affecting the Hh pathway, an important factor in BA pathogenesis. PMID:27526058

    It has been reported recently that there is a unique distribution of the E2 subunit of the pyruvate dehydrogenase complex (PDC-E2) on biliary epithelial cells in patients with primary biliary cirrhosis (PBC) but not primary sclerosing cholangitis. This distribution has been demonstrated using a mouse monoclonal antibody, coined C355.1. The epitope recognized by C355.1 is near the lipoic acid binding site of PDC-E2. C355.1 inhibits PDC-E2 activity in vitro and, unlike a panel of other monoclonal antibodies against different regions of PDC-E2, appears to bind not only to mitochondria but also to a unique antigen expressed predominantly on the luminal side of biliary epithelial cells in PBC. We have extended these observations by studying the subcellular reactivity of C355.1 using postembedding immunoelectron microscopy on the intrahepatic small bile ducts of PBC livers, extrahepatic biliary obstruction (EBO) livers, and normal livers. We report that the reactivity of C355.1 can be classified into two categories. The first category is characterized by small foci of reaction products that were randomly dispersed in cytoplasm, particularly in supranuclear areas; the ultrastructural characterization of these foci was impossible to define but was similar in PBC and EBO. However, of particular interest was the second category of reactivity, which was characterized by deposition of reaction products around the biliary lumen, including microvilli and adjacent subluminal ectoplasm and secretory substances in the biliary lumen. This staining pattern was frequent in PBC livers, only occasionally evident in EBO livers, and not found in normal livers. These data further define and highlight the unique subcellular distribution of PDC-E2 around the biliary lumen in PBC livers and suggest that this abnormality is related to the pathogenesis of bile duct lesions.

    AIM To evaluate complications and management outcomes of retained long-term plastic biliary stents. METHODS Endoscopic plastic biliary stent placement was performed in 802 patients at Yeungnam University Hospital between January 2000 and December 2014. Follow-up loss with a subsequently forgotten stent for more than 12 mo occurred in 38 patients. We retrospectively examined the cause of biliary stent insertion, status of stents, complications associated with biliary stents and management outcomes of long-term plastic biliary stents. Continuous variables were analyzed using the t test. Observed frequencies in subsets of the study population were compared using Fisher’s exact test and χ2 tests. Statistical significance was defined as P < 0.05 (two-tailed). RESULTS Mean age of patients was 73.7 ± 12 years and male-to-female ratio was 2.2:1. Indications of plastic biliary stent insertion were bile duct stones (63.2%, 24/38) and benign bile duct stricture (52.6%, 20/38). Mean duration of retained plastic stent was 22.6 ± 12.2 mo, and in 10 cases (26.3%), stents were retained for more than 24 mo. Common bile duct (CBD) stones or sludge were found in most cases (92.1%, 35/38). The most common complication was acute cholangitis (94.7%, 36/38). Stent removal by endoscopic approach was successfully performed in 92.1% (35/38) of the cases. In 3 cases, an additional plastic stent was inserted alongside the previous stent due to failure of the stent removal. Endoscopic removal of bile duct stones was successful in 73.7% (28/38) of the cases. When patients were divided into two groups by duration of stent placement (12 to 24 mo vs over 24 mo), there were no differences in the development of cholangitis, presence of biliary stones, and success rate of endoscopic removal of stones and biliary stents. CONCLUSION The most common complication of retained long-term plastic biliary stents was acute cholangitis associated with CBD stones. Endoscopic management was successfully

    The epidemiological patterns for pancreatic and biliary cancers reveal more differences than similarities. Pancreatic carcinoma is common in western countries, although 2 Polynesian groups (New Zealand Maoris and native Hawaiians) have the highest rates internationally. In the United States the disease is rising in frequency, predominating in males and in blacks. The rates are elevated in urban areas, but geographic analysis uncovered no clustering of contiguous counties except in southern Louisiana. The origin of pancreatic cancer is obsure, but a twofold increased risk has been documented for cigarette smokers and diabetic patients. Alcohol, occupational agents, and dietary fat have been suspected, but not proven to be risk factors. Except for the rare hereditary form of pancreatitis, there are few clues to genetic predisposition. In contrast, the reported incidence of biliary tract cancer is highest in Latin American populations and American Indians. The tumor predominates in females around the world, except for Chinese and Japanese who show a male excess. In the United States the rates are higher in whites than blacks, and clusters of high-risk counties have been found in the north central region, the southwest, and Appalachia. The distribution of biliary tumors parallels that of cholesterol gallstones, the major risk factor for biliary cancer. Insights into biliary carcinogenesis depend upon clarification of lithogenic influences, such as pregnancy, obesity, and hyperlipoproteinemia, exogenous estrogens, familial tendencies, and ethnic-geographic factors that may reflect dietary habits. Noncalculous risk factors for biliary cancer include ulcerative colitis, clonorchiasis, Gardner's syndrome, and probably certain industrial exposures. Within the biliary tract, tumors of the gallbladder and bile duct show epidemiological distinctions. In contrast to gallbladder cancer, bile duct neoplasms predominate in males; they are less often associated with stones and more

    As measured by whole body retention of isotopic calcium given in milk, absorption of calcium was impaired in 10 patients with chronic parenchymal non-biliary liver disease who were icteric. Mean absorption was normal in 15 patients with parenchymal liver disease who were anicteric although some individual patients absorbed less than any of the controls. Depressed absorption of calcium was seen in 10 patients with primary biliary cirrhosis and seven patients with intra- or extra-hepatic biliary obstructive disease. The most likely cause for this malabsorption is reduced bile salt secretion into the intestinal lumen which impairs vitamin D and fat absorption. The finding that parenteral vitamin D increased calcium absorption to normal levels in five patients with primary biliary cirrhosis suggests that deficiency of this vitamin is a major and correctable factor leading to calcium malabsorption in such patients. Precipitation of calcium salts by excess intraluminal fat appears to be a further possible factor reducing calcium absorption in these patients. These findings emphasize the importance of parenteral vitamin D therapy in patients with chronic obstructive biliary diseases. They also suggest that certain patients with chronic parenchymatous liver disease, particularly those who are icteric, may also occasionally require therapy with vitamin D. PMID:5171934

    Background Early biliary complications (EBC) following pancreaticoduodenectomy (PD) are poorly known. This study aimed to assess incidence, predictive factors, and treatment of EBC including bilio-enteric stricture, transient jaundice, biliary leak, and cholangitis. Method From 2007 to 2011, 352 patients underwent PD. Statistical analysis including logistic regression was performed to determine EBC predictive factors. Results 49 patients (14%) developed 51 EBC, including 7(2%) bilio-enteric strictures, 15(4%) transient jaundices, 9(3%) biliary leaks, and 20(6%) cholangitis with no mortality and a 18% reoperation rate. In multivariate analysis, male gender, benign disease, malignancy with preoperative chemoradiation, and common bile duct (CBD) diameter ≤5 mm were predictive of EBC. Of the 7 strictures, all were associated with CBD ≤5 mm and 5(71%) required reoperation. Transient jaundice resolved spontaneously in all 15 cases. Among 8 patients with serum bilirubin level >50 μmol/L (3 mg/dL) at POD3, 7(88%) developed bilio-enteric stricture. Biliary leak resolved spontaneously in 5(56%); otherwise, it required reoperation. Cholangitis recurred after antibiotics discontinuation in 5(25%). Conclusions EBC following PD do not increase mortality. EBC are more frequent with male gender, benign disease, malignancy with preoperative chemoradiation, and CBD ≤5 mm. Transient jaundice or cholangitis has a favorable outcome, whereas bilio-enteric stricture or biliary leak can require reintervention. PMID:27037207

    Situs inversus totalis is is a congenital anomaly associated with various visceral abnormalities, but there is no data about the relationship between secondary biliary cirrhosis and that condition. We here present a case of a 58 year-old female with situs inversus totalis who was admitted to our clinic with extrahepatic cholestasis. After excluding all potential causes of biliary cirrhosis, secondary biliary cirrhosis was diagnosed based on the patient's history, imaging techniques, clinical and laboratory findings, besides histolopathological findings. After treatment with tauroursodeoxycholic acid, all biochemical parameters, including total/direct bilirubin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and gama glutamyl transferase, returned to normal ranges at the second month of the treatment. We think that this is the first case in literature that may indicate the development of secondary biliary cirrhosis in a patient with situs inversus totalis. In conclusion, situs inversus should be considered as a rare cause of biliary cirrhosis in patients with situs inversus totalis which is presented with extrahepatic cholestasis. PMID:21813017

    Three patients with malignant biliary obstruction were treated with placement of metallic biliary stents. Two patients had known partial duodenal stenosis but had no symptoms of gastrointestinal obstruction. The patients developed symptomatic duodenal obstruction early after biliary metallic stent placement. The symptomatic duodenal obstructions were successfully treated with peroral placement of duodenal stents, which obviated the need for surgical intervention.

    The failure rate of endoscopic retrograde cholangiopancreatography for biliary cannulation is approximately 6%–7% in cases of obstructive jaundice. Percutaneous transhepatic biliary drainage (PTBD) is the procedure of choice in such cases. Endoscopic ultrasound-guided biliary drainage (EGBD) is a novel technique that allows biliary drainage by echoendoscopy and fluoroscopy using a stent from the biliary tree to the gastrointestinal tract. Information in PubMed, Scopus, clinicaltrials.gov and Cochrane review were analyzed to obtain studies comparing EGBD and PTBD. Six studies fulfilled the inclusion criteria. Technical (odds ratio (OR): 0.34; confidence interval (CI) 0.10–1.14; p=0.05) and clinical (OR: 1.48; CI 0.46–4.79; p=0.51) success rates were not statistically significant between the EGBD and PTBD groups. Mild adverse events were nonsignificantly different (OR: 0.36; CI 0.10–1.24; p=0.11) but not the moderate-to-severe adverse events (OR: 0.16; CI 0.08–0.32; p≤0.00001) and total adverse events (OR: 0.34; CI 0.20–0.59; p≤0.0001). EGBD is equally effective but safer than PTBD.

    Cholangiocarcinoma and pancreatic head cancer are still linked with extremely high 5-year mortality in the western world. The management of such patients is complex and typically requires a multidisciplinary approach in a tertiary care center. Interventional radiology offers minimally invasive, image-guided treatment for a variety of diseases and conditions. Regarding patients with malignant biliary obstruction, IR options are considered for more than two decades as a valid management tool for both operable and non-operable cases. The options include placement of percutaneous transhepatic biliary drains, preoperative embolization of the portal vein and deployment of covered and uncovered biliary stents. The purpose of this review is to describe the current evidence in this continuously evolving field. PMID:26752947

    High surgical mortality in patients with obstructive jaundice and sepsis have been attributed to reticuloendothelial system (RES) depression. The purpose of this study was to clarify the effects of mechanical biliary obstruction on RES clearance of pathogenic bacteria by comparing the phagocytic index (K) with the directly measured hepatic uptake of indium 111-labeled bacteria injected into the portal vein of normal dogs and dogs with partial (PBO) or complete biliary obstruction (CBO). No significant difference was observed between the K in normal dogs (0.19 +/- 0.08; n = 6) and that in dogs with PBO (0.24 +/- 0.06; n = 5) or CBO (0.21 +/- 0.03; n = 4). There was no significant difference in uptake of radiolabel by the liver among the three groups of dogs. In our model, biliary obstruction had no effect on hepatic RES function and may not represent a significant determinant of mortality in patients with obstructive jaundice.

    2016-10-01

    Mixed adenoneuroendocrine carcinomas (MANECs) are composite neoplasms with areas of adenocarcinoma or squamous cell carcinoma intermingled with neuroendocrine carcinoma or neuroendocrine tumor, each composing at least 30% of the neoplasm. MANECs are very infrequent overall, and they are more commonly diagnosed in the appendix, colon, and stomach. Biliary MANECs are particularly rare, and their histogenesis is debated because neuroendocrine cells are seldom identified in the normal biliary tract. They can show one of the 3 different architectural patterns described in Lewin's original classification: collision tumors, combined lesions, or amphicrine neoplasms. The neuroendocrine component is usually of a high grade, with small or large cell cytomorphology, whereas the adenocarcinoma component is either an intestinal or biliary type. Clinical presentation is characterized by locally advanced disease at the time of initial diagnosis. Recent studies suggest that treatment should be guided by the most aggressive histologic component.

    Biliary atresia (BA) is the major cause of cholestasis and the leading indication for liver transplantation (LT). However, the incidence of BA in Korea has not been reported. The aim of this study was to investigate the incidence and clinical outcomes of BA in Korea. We used the Korean universal health insurance database and extracted data regarding BA patients younger than 18 years of age admitted between 2011 and 2015. The incidence of BA was calculated by dividing the number of BA patients by the number of live births. Two hundred forty infants were newly diagnosed with BA. A total of 963 BA patients younger than 18 years of age were followed up for 5 years. The overall incidence of BA was 1.06 cases per 10,000 live births. The incidence of BA was 1.4 times higher for female patients than for male patients. Additionally, significant seasonal variation was observed; in particular, the incidence of BA was 2 times higher from June through August than from December through February. Congenital anomalies were found in 38 of 240 patients (15.8%). Congenital heart diseases were major associated congenital anomalies (6.3%). Several complications developed during the study period, including cholangitis (24.0%), varix (6.2%), and gastrointestinal bleeding (4.4%). Three hundred and one of the 963 BA patients under 18 years of age (31.3%) received LT for BA. The incidence of BA is higher in Korea than that in Western countries. We also report significant gender-associated differences and seasonal variation with respect to the incidence of BA. PMID:28244293

    A novel DNA virus (TT virus; TTV) was isolated from a patient with post-transfusion hepatitis of unknown etiology. If TTV replicates in the liver, TTV may appear in the bile. In the present study, to clarify whether fecal-oral infection occur via biliary excretion, the presence of TTV DNA was assessed in paired serum and bile samples collected from 28 patients with obstructive jaundice without parenchymal liver disease. TTV DNA was detected by polymerase chain reaction (PCR) using semi-nested primers, and quantified by Real Time Detection PCR (RTD-PCR). The nucleotide sequence of isolates TTV DNAs was also determined and the sequences were compared between serum and bile samples. Among 28 patients, 7 were positive for TTV DNA in both samples, and 3 and 2 were positive in serum and bile respectively. Of 7 patients positive for TTV DNA in both samples, the TTV DNA titer was higher in serum of 4 patients and in bile of 1 patient. Among 7 patients positive for TTV DNA in serum and bile, 6 had the same sequence in both samples. Multiple distinct types of TTV DNA clones were isolated from serum in 2 patients and from bile in 4 patients. In conclusion, TTV DNA is detected frequently in bile from patients with obstructive jaundice, suggesting a fecal-oral route of infection and high prevalence of asymptomatic TTV carriers. TTV DNA was detected only in serum from some patients, suggesting that replication of TTV may occur in other organs as well as in the liver.

    Trends in biliary tract cancer incidence rates have increased in Shanghai, China. These trends have coincided with economic and developmental growth, as well as a shift in dietary patterns to a more Westernized diet. To examine the effect of dietary changes on incident disease, we evaluated associations between diet and biliary tract cancers amongst men and women from a population-based case-control study in Shanghai, China. Biliary tract cancer cases were recruited from 42 collaborating hospitals in urban Shanghai, and population-based controls were randomly selected from the Shanghai Household Registry. Food frequency questionnaire data were available for 225 gallbladder, 190 extrahepatic bile duct, and 68 ampulla of Vater cancer cases. A total of 39 food groups were created and examined for associations with biliary tract cancer. Interestingly, only four food groups demonstrated a suggested association with gallbladder, extrahepatic bile duct, or ampulla of Vater cancers. The allium food group, consisting of onions, garlic, and shallots showed an inverse association with gallbladder cancer (OR: 0.81, 95% CI: 0.68-0.97). Similar trends were seen in the food group containing seaweed and kelp (OR: 0.79, 95% CI: 0.67-0.96). In contrast, both preserved vegetables and salted meats food groups showed positive associations with gallbladder cancer (OR:1.27, 95% CI: 1.06-1.52; OR: 1.18, 95% CI: 1.02-1.37, respectively). Each of these four food groups showed similar trends for extrahepatic bile duct and ampulla of Vater cancers. The results of our analysis suggest intake of foods with greater anti-inflammatory properties may play a role in decreasing the risk of biliary tract cancers. Future studies should be done to better understand effects of cultural changes on diet, and to further examine the impact diet and inflammation have on biliary tract cancer incidence.

    Primary biliary cirrhosis (PBC) is a chronic autoimmune disease characterised by cholestatic liver function tests, antimitochondrial antibodies, and abnormal liver histology. Early descriptions of a rare rapidly progressive disease no longer reflect the more indolent progress often seen today. Many patients have significant long term morbidity through symptoms such as fatigue and itch with a minority progressing to liver failure and need for transplantation. The current data on the diagnosis, clinical progression, and treatment of PBC are reviewed.

    Congenital tracheo-or-bronchobiliary fistula or congenital he-patopulmonary fistula is a rare malformation with high morbidity and mortality if the diagnosis is not made early. The tracheo-or-bronchobiliary fistula is a communication between the respiratory (trachea or bronchus) and biliary tract. To date, only 35 cases have been published worldwide. We report a case of a neonate with right pneumonia and bilious fluid in the endotracheal tube. Diagnosis was made using bronchoscopy with fluoroscopy. Videothoracoscopy was used to remove the bronchobiliary fistula. Subsequently, a left he-patectomy with Roux-en-Y biliary-digestive anastomosis was performed as bile ductus hypoplasia was present.

    There are many autoimmune diseases associated with primary biliary cholangitis (PBC), known as primary biliary cirrhosis; however, the association between PBC and warm autoimmune hemolytic anemia (wAIHA) has rarely been reported. It is documented that hemolysis is present in over 50% of the patients with chronic liver disease, regardless of the etiologies. Due to the clear and frequent relationship between PBC and many autoimmune diseases, it is reasonable to suppose that wAIHA may be another autoimmune disorder seen in association with PBC. Here we reported a 53-year-old female patient diagnosed with wAIHA associated with PBC.

    The aim of the study was the macromorphological analysis of extrahepatic biliary tract in chinchilla (Chinchilla laniger Molina). Bile ducts, the gall bladder and portal vein were injected with coloured latex. Using the technique of dissection, bile ducts were isolated from the liver lobes. It was found that the cystic duct in this species is rarely single. Hepatic ducts form a system of multiple anastomosing structures running in the hepatoduodenal ligament. Many bile duct openings were observed in the duodenal papilla. The results confirm wide variations of the biliary tract in mammals and may be important for comparative analysis of the morphological differentiation of these structures in small mammals.

    Fully covered self-expanding metal stents (FCSEMSs) are now being used to treat postoperative biliary strictures (BSs) and biliary leaks (BLs). The aim of this study was to assess the safety and effectiveness of a new FCSEMS (Wallflex) in patients with postoperative BSs and BLs after failure of traditional endoscopic treatment. Between January 2010 and December 2011, 16 patients (10 patients with postcholecystectomy BSs, 4 with postcholecystectomy BLs, and 2 with postorthotopic liver transplantation BSs) were enrolled. The technical and clinical success rate was 100%. All FCSEMSs were removed after a mean of 141 days. Complications occurred in 7 cases: 2 postprocedure pain, 2 mild pancreatitis, 1 early distal, and 2 late proximal FCSEMS migration. The overall long-term clinical success rate was 94% after a mean follow-up of 13 months. In our experience, the placement of FCSEMSs is an effective and secure method of treating refractory postoperative BSs or BLs.

    Sexual pain is an underrecognized and poorly treated constellation of disorders that significantly impact affected women and their partners. Recognized as a form of chronic pain, sexual pain disorders are heterogeneous and include dyspareunia (superficial and deep), vaginismus, vulvodynia, vestibulitis, and noncoital sexual pain disorder. Women too often tolerate pain in the belief that this will meet their partners' needs. This article provides a review of the terminology and definition of the condition, theories on the pathophysiology, diagnostic considerations, and recommendations on the management of female sexual pain.

    Endoscopic ultrasound (EUS) is a major advance in gastrointestinal endoscopy. EUS, which is invaluable in the diagnosis and staging of gastrointestinal cancer, is now being used in the diagnosis of chronic upper abdominal pain. EUS combined with stimulated biliary drainage (EUS/SBD) aids in the diagnosis of choledocholithiasis, cholecystitis, microlithiasis, and various conditions of the upper gastrointestinal tract. This article describes the EUS/SBD procedure and nursing care. Two case histories illustrating potential benefits to patients are presented.

    Although the development of de novo autoimmune liver disease after liver transplantation (LT) has been described in both children and adults, autoimmune hepatitis (AIH)-primary biliary cirrhosis (PBC) overlap syndrome has rarely been seen in liver transplant recipients. Here, we report a 50-year-old man who underwent LT for decompensated liver disease secondary to alcoholic steatohepatitis. His liver function tests became markedly abnormal 8 years after LT. Standard autoimmune serological tests were positive for anti-nuclear and anti-mitochondrial antibodies, and a marked biochemical response was observed to a regimen consisting of prednisone and ursodeoxycholic acid added to maintain immunosuppressant tacrolimus. Liver biopsy showed moderate bile duct lesions and periportal lymphocytes infiltrating along with light fibrosis, which confirmed the diagnosis of AIH-PBC overlap syndrome. We believe that this may be a case of post-LT de novo AIH-PBC overlap syndrome; a novel type of autoimmune overlap syndrome.

    Abstract Although radiofrequency (RF) ablation has been accepted as a curative treatment modality for solid organ tumors, intraductal RF ablation for malignant biliary obstruction has not been widely described. The aim of this study was to evaluate the feasibility, safety, and efficacy (in terms of stent patency and survival) of intraductal RF ablation combined with biliary stent placement for nonresectable malignant biliary obstruction. A search of the nonresectable malignant extrahepatic biliary obstruction database (179 patients) identified 18 consecutive patients who were treated with biliary intraluminal RF ablation during percutaneous transhepatic cholangiodrainage and inner stent placement (RF ablation group) and 18 patients who underwent inner stent placement without biliary intraluminal RF ablation (control group). The patients were matched for tumor type, location of obstruction, tumor stage, and Child–Pugh class status. Primary endpoints included safety, stent patency time, and survival rates. The secondary endpoint was effectiveness of the technique. The RF ablation and control groups were closely matched in terms of age, diagnosis, presence of metastases, presence of locally advanced tumor, American Society of Anesthesiologists (ASA) grade, and chemotherapy regimen (all P > 0.05). The technical success rate for both groups was 100%. The median time of stent patency in the RF ablation and control groups were 5.8 (2.8–11.5) months and 4.5 (2.4–8.0) months, respectively (Kaplan–Meier analysis: P = 0.03). The median survival times in the RF ablation and control groups were 6.1 (4.8–15.2) months and 5.8 (4.2–16.5) months, with no significant difference according to Kaplan–Meier analysis (P = 0.45). In univariate and multivariate analyses, poorer overall survival was associated with advanced age and presence of metastases (P < 0.05).

    Many disorders of the liver, gallbladder, and biliary tree may cause right upper quadrant pain and clinical diagnosis may be challenging. Imaging plays a key role in establishing a prompt diagnosis and guiding appropriate management. Although ultrasonography is the initial imaging modality of choice for most hepatobiliary disorders, radionuclide imaging, computed tomography (CT), and MR imaging also play important roles. Acute cholecystitis may be associated with many complications that have characteristic imaging features. MR cholangiopancreatography achieves high accuracy in diagnosis of choledocholithiasis and allows for noninvasive imaging when ultrasonography and CT are indeterminate.

    Therapeutic access to the biliary system is generally limited to endoscopic or percutaneous approaches. A variety of percutaneous transhepatic biliary interventions are applicable for the diagnosis and treatment of biliary system pathologies, the majority of which may be performed in conjunction with one another. The backbone of nearly all of these interventions is percutaneous transhepatic cholangiography for opacification of the biliary tree, after which any number of therapeutic or diagnostic modalities may be pursued. We describe an overview of the instrumentation and technical approaches for several fundamental interventional procedures, including percutaneous transhepatic cholangiography and internal/external biliary drainage, endobiliary biopsy techniques, cholangioscopy, cholangioplasty and biliary stenting, biliary stone extraction, and intraluminal brachytherapy.

    Liver resection is widely accepted as the only potentially curative treatment in malignant or benign hepatobiliary lesions. Although not frequent, biliary leakage is a postoperative complication which may have considerable consequences. The field of topical hemostatic agents is rapidly developing, with various products currently available. This article reviews the risk factors associated with biliary leakage and the methods used for testing or prevention of biliary leakage. A literature search was performed using key words related to experimental and clinical studies dealing with biliary leakage. Experimental studies assessed the potential bilio-static effect of different topical hemostatic agents after bile duct reconstruction. Clinical series show biliary leakage rates up to 12%. There is no evidence that flushing of the bile duct system after resection reduces the incidence of biliary leakage. Further controlled studies are needed to clarify the preventive effect of topical hemostatic agents on biliary leakage after liver resection.

    Absorption of radiolabeled cobalamin in baboons was assessed by whole body counting. Retention of biliary cobalamin and an aqueous solution of cyanocobalamin was measured in normal baboons and in baboons after total gastrectomy by using /sup 57/Co-labeled biliary cobalamin and /sup 58/C0-cyanocobalamin, with and without baboon gastric juice containing intrinsic factor. Radiolabeled biliary cobalamin was obtained by intravenous injection of /sup 57/Co-cyanocobalamin in baboons and collection of bile through a cannula placed in the common bile duct. Cobalamin absorption was not completely abolished by gastrectomy and biliary cobalamin was better retained than cyanocobalamin; intrinsic factor enhanced absorption of both forms. After gastrectomy there was steady depletion of liver and serum cobalamin levels, which ceased after a new equilibrium was reached between a progressively diminishing cobalamin loss and the impaired but significant residual level of absorption. These studies in the nonhuman primate provide further information concerning the enterohepatic circulation of cobalamin and suggest that the form of cobalamin in bile may be more readily absorbed than is cyanocobalamin or that bile itself may have an enhancing effect on cobalamin absorption. The data also suggest that physiologically significant amounts of cobalamin may be absorbed in the absence of a gastric source of intrinsic factor.

    The precipitation of excess biliary cholesterol as solid crystals is a prerequisite for cholesterol gallstone formation, which occurs due to disturbed biliary homeostasis. Biliary homeostasis is regulated by an elaborate network of genes in hepatocytes. If unmanaged, the cholesterol crystals will aggregate, fuse and form gallstones. We have previously observed that the levels of osteopontin (OPN) in bile and gallbladder were reduced in gallstone patients. However, the role and mechanism for hepatic OPN in cholesterol gallstone formation is undetermined. In this study, we found that the expression of hepatic OPN was increased in gallstone patients compared with gallstone-free counterparts. Then, we observed that OPN-deficient mice were less vulnerable to cholesterol gallstone formation than wild type mice. Further mechanistic studies revealed that this protective effect was associated with alterations of bile composition and was caused by the increased hepatic CYP7A1 expression and the reduced expression of hepatic SHP, ATP8B1, SR-B1 and SREBP-2. Finally, the correlations between the expression of hepatic OPN and the expression of these hepatic genes were validated in gallstone patients. Taken together, our findings reveal that hepatic OPN contributes to cholesterol gallstone formation by regulating biliary metabolism and might be developed as a therapeutic target for gallstone treatments.

    Background Biliary leak can occur as a complication of biliary surgery, endoscopic retrograde cholangiopancreatography manipulations and endoscopic biliary sphincterotomy. Consequently, bile may collect in the abdominal cavity, a condition called biloma. Rarely, it may reach a massive size. Case presentation A 72-year-old man presented with gastric upset with gradual abdominal distension reaching a large size due to intra-abdominal bile collection (biloma) after endoscopic retrograde cholangiopancreatography plus endoscopic biliary sphincterotomy and stenting for post laparoscopic cholecystectomy common bile duct stricture. This huge biloma was treated by percutaneous insertion of a tube drain for a few days, evacuating the collection successfully without recurrence. Discussion This patient might sustain injury to the common bile duct either by the guide wire or stent, or the injury occurred at the angle between the common bile duct and duodenum during sphincterotomy of the ampulla. Although any of these rents may lead to a bile leak, causing a huge biloma, they could be successfully treated by percutaneous drainage. Conclusions (1) Following endoscopic retrograde cholangiopancreatography, a patient’s complaints should not be ignored. (2) A massive biloma can occur due to such procedures. (3) Conservative treatment with minimal invasive technique can prove to be effective. PMID:26402876

    Biliary atresia (BA) is a rapidly progressive and destructive fibrotic disorder of unknown etiology affecting the extrahepatic biliary tree of neonates. Epidemiological studies suggest that an environmental factor, such as a virus or toxin, is the cause of the disease, although none have been definitively established. Several naturally occurring outbreaks of BA in Australian livestock have been associated with the ingestion of unusual plants by pregnant animals during drought conditions. We used a biliary secretion assay in zebrafish to isolate a previously undescribed isoflavonoid, biliatresone, from Dysphania species implicated in a recent BA outbreak. This compound caused selective destruction of the extrahepatic, but not intrahepatic, biliary system of larval zebrafish. A mutation that enhanced biliatresone toxicity mapped to a region of the zebrafish genome that has conserved synteny with an established human BA susceptibility locus. The toxin also caused loss of cilia in neonatal mouse extrahepatic cholangiocytes in culture and disrupted cell polarity and monolayer integrity in cholangiocyte spheroids. Together, these findings provide direct evidence that BA could be initiated by perinatal exposure to an environmental toxin. PMID:25947162

    Cholelithiasis is the most common cause of acute pancreatitis, accounting 35%-60% of cases. Around 15%-20% of patients suffer a severe attack with high morbidity and mortality rates. As far as treatment is concerned, the optimum method of late management of patients with severe acute biliary pancreatitis is still contentious and the main question is over the correct timing of every intervention. Patients after recovering from an acute episode of severe biliary pancreatitis can be offered alternative options in their management, including cholecystectomy, endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy, or no definitive treatment. Delaying cholecystectomy until after resolution of the inflammatory process, usually not earlier than 6 wk after onset of acute pancreatitis, seems to be a safe policy. ERCP and sphincterotomy on index admission prevent recurrent episodes of pancreatitis until cholecystectomy is performed, but if used for definitive treatment, they can be a valuable tool for patients unfit for surgery. Some patients who survive severe biliary pancreatitis may develop pseudocysts or walled-off necrosis. Management of pseudocysts with minimally invasive techniques, if not therapeutic, can be used as a bridge to definitive operative treatment, which includes delayed cholecystectomy and concurrent pseudocyst drainage in some patients. A management algorithm has been developed for patients surviving severe biliary pancreatitis according to the currently published data in the literature. PMID:27678352

  19. Role of lipid peroxidation in biliary obstruction in the rat.

    PubMed

    Muriel, P; Suarez, O R

    1994-01-01

    There is poor evidence about the participation of lipoperoxidative processes in liver damage induced by biliary obstruction, thus the aim of this work was to study the role of lipid peroxidation in this model of liver injury. Biliary obstruction was induced in male Wistar rats by ligation of the common bile duct; control animals were sham operated. Rats were sacrificed at different times after surgery. Liver sections were used for glycogen and lipoperoxidation quantification. Markers of liver damage were determined in serum. All serum markers of liver damage increased after 1 day of biliary obstruction. Liver glycogen content decreased 1 day after surgery. On the other hand, lipoperoxidation increased later than markers of liver damage, suggesting that it is a consequence rather than the cause of liver injury. Moreover, administration of colchiceine (a good free-radical scavenger) or vitamin E prevented lipoperoxidation but not liver damage, confirming that lipoperoxidation does not play an important role in liver damage induced by biliary obstruction. This model of liver injury seems to be useful for testing hepatoprotective drugs that do not act as free-radical scavengers.

  20. Regional Differences in Hospitalizations and Cholecystectomies for Biliary Dyskinesia

    2013-01-01

    Background/Aims Published studies suggest that socioeconomic factors contribute to increasing cholecystectomy rates for biliary dyskinesia (BD). The aim of this study was to identify factors driving admissions and operations for BD by examining regional variability in hospitalizations and cholecystectomies for this disorder. Methods Annual hospitalizations and cholecystectomy rates for biliary diseases were assessed using the State Inpatient Databases of the Agency for Healthcare Research and Quality based on diagnosis codes for biliary dyskinesia, cholecystolithiasis and cholecystitis. Results Annual admissions for BD varied nearly sevenfold among different states within the United States. Hospitalizations for gallstone disease and its complication showed less variability, differing 2-fold between states. Nearly 70% of admissions for BD and about 85% of admissions for gallstone disease resulted in cholecystectomies. Higher admission rates for BD were best predicted by high overall hospitalization rates, admission rate for gallstone disease and the physician workforce within a state. Cholecystectomy rates for BD were higher in states with low population density and high rates of cholecystectomy for gallstone disease. Conclusions These data suggest that established medical practice patterns significantly contribute to the variability in admissions and operations for biliary dyskinesia. The findings also indicate that lower thresholds for operative interventions are an important determinant in the approach to this disorder. Considering the benign course of functional illnesses, the bar for surgical interventions should be raised rather than lowered; in addition active conservative treatment options should be developed for these patients.

    Patients with periampullary cancer or gastric cancer often develop malignant biliary obstruction (MBO) and gastric outlet obstruction (GOO), and combined MBO and GOO is not rare in these patients. Combined MBO and GOO is classified by its location and sequence, and treatment strategy can be affected by this classification. Historically, palliative surgery, hepaticojejunostomy and gastrojejunostomy were carried out, but the current standard treatment is combined transpapillary stent and duodenal stent placement. Although a high technical success rate is reported, the procedure can be technically difficult and duodenobiliary reflux with subsequent cholangitis is common after double stenting. Recent development of endoscopic ultrasound (EUS)-guided procedures enables the management of MBO as well as GOO under EUS guidance. EUS-guided biliary drainage is now increasingly reported as an alternative to percutaneous transhepatic biliary drainage in failed endoscopic retrograde cholangiopancreatography (ERCP), and GOO is one of the major reasons for failed ERCP. In addition to EUS-guided biliary drainage, the feasibility of EUS-guided double-balloon-occluded gastrojejunostomy bypass for MBO was recently reported, and EUS-guided double stenting can potentially become the treatment of choice in the future. However, as each procedure has its advantages and disadvantages, treatment strategy should be selected based on the type of obstruction and the prognosis and performance status of the patient.

    AIM: To provide consensus statements on the use of per-oral cholangiopancreatoscopy (POCPS). METHODS: A workgroup of experts in endoscopic retrograde cholangiopancreatography (ERCP), endosonography, and POCPS generated consensus statements summarizing the utility of POCPS in pancreaticobiliary disease. Recommendation grades used validated evidence ratings of publications from an extensive literature review. RESULTS: Six consensus statements were generated: (1) POCPS is now an important additional tool during ERCP; (2) in patients with indeterminate biliary strictures, POCS and POCS-guided targeted biopsy are useful for establishing a definitive diagnosis; (3) POCS and POCS-guided lithotripsy are recommended for treatment of difficult common bile duct stones when standard techniques fail; (4) in patients with main duct intraductal papillary mucinous neoplasms (IPMN) POPS may be used to assess extent of tumor to assist surgical resection; (5) in difficult pancreatic ductal stones, POPS-guided lithotripsy may be useful in fragmentation and extraction of stones; and (6) additional indications for POCPS include selective guidewire placement, unexplained hemobilia, assessing intraductal biliary ablation therapy, and extracting migrated stents. CONCLUSION: POCPS is important in association with ERCP, particularly for diagnosis of indeterminate biliary strictures and for intra-ductal lithotripsy when other techniques failed, and may be useful for pre-operative assessment of extent of main duct IPMN, for extraction of difficult pancreatic stones, and for unusual indications involving selective guidewire placement, assessing unexplained hemobilia or intraductal biliary ablation therapy, and extracting migrated stents.

    2010-12-15

    Percutaneous cholecystostomy is a minimally invasive procedure for providing gallbladder decompression, often in critically ill patients. It can be used in malignant biliary obstruction following failed endoscopic retrograde cholangiopancreatography when the intrahepatic ducts are not dilated or when stent insertion is not possible via the bile ducts. In properly selected patients, percutaneous cholecystostomy in obstructive jaundice is a simple, safe, and rapid option for biliary decompression, thus avoiding the morbidity and mortality involved with percutaneous transhepatic biliary stenting. Subsequent use of a percutaneous cholecystostomy for definitive biliary stent placement is an attractive concept and leaves patients with no external drain. To the best of our knowledge, it has only been described on three previous occasions in the published literature, on each occasion forced by surgical or technical considerations. Traditionally, anatomic/technical considerations and the risk of bile leak have precluded such an approach, but improvements in catheter design and manufacture may now make it more feasible. We report a case of successful interval metal stent placement via percutaneous cholecystostomy which was preplanned and achieved excellent palliation for the patient. The pros and cons of the procedure and approach are discussed.

    Background/Aims: Endoscopic retrograde biliary drainage (ERBD) has become a standard procedure in patients with a biliary obstruction. Intraductal ultrasonography (IDUS) has emerged as a new tool for managing extrahepatic biliary diseases. IDUS-directed ERBD can be performed without conventional cholangiography (CC). The goal of this study was to assess the effectiveness and safety of IDUS-directed ERBD compared to CC-directed ERBD in patients with an extrahepatic biliary obstruction. Methods: A total of 210 patients who had undergone IDUS-directed ERBD (IDUS-ERBD, n = 105) and CC-directed ERBD (CC-ERBD, n = 105) between October 2013 and April 2014 were analyzed retrospectively. The primary outcome measure was the procedural success rate. Secondary outcome measures included clinical outcomes, total procedure time, radiation exposure time, and overall complication rates. Results: The total technical success rate of ERBD was 100% (105/105) in the IDUS-ERBD and CC-ERBD groups. Mean procedure time was slightly prolonged in the IDUS-ERBD group than that in the CC-ERBD group (32.1 ± 9.9 minutes vs. 28.4 ± 11.6 minutes, p = 0.023). Mean radiation exposure time was one-third less in the IDUS-ERBD group than that in the CC-ERBD group (28.0 ± 49.3 seconds vs. 94.2 ± 57.3 seconds, p < 0.001). No significant differences in complication rates were detected between the groups. Conclusions: IDUS-ERBD was equally effective and safe as CC-ERBD in patients with an extrahepatic biliary obstruction. Although IDUS-ERBD increased total procedure time, it significantly decreased radiation exposure. PMID:27097771

    Objectives To quantify health related quality of life (HRQOL) of patients with biliary atresia with their native livers and compare them with healthy children and patients with biliary atresia post-liver transplant (LT) and to examine the relationship between HRQOL and medical variables. Study design A cross-sectional HRQOL study of patients with biliary atresia with their native livers (ages 2-25 years) was conducted and compared with healthy and post-LT biliary atresia samples using PedsQL™ 4.0 child self and parent proxy reports, a validated measure of physical/psychosocial functioning. Results 221 patients with biliary atresia with native livers (54% female, 67% white) were studied. patient self and parent proxy reports showed significantly poorer HRQOL than healthy children across all domains (p < 0.001), particularly in emotional and psychosocial functioning. Child self and parent proxy HRQOL scores from patients with biliary atresia with their native livers and post-LT biliary atresia were similar across all domains (p=NS). Child self and parent proxy reports showed moderate agreement across all scales, except social functioning (poor to fair agreement). On multivariate regression analysis, black race and elevated total bilirubin were associated with lower Total and Psychosocial HRQOL summary scores. Conclusions HRQOL in patients with biliary atresia with their native livers is significantly poorer than healthy and similar to post-LT biliary atresia children. These findings identify significant opportunities to optimize the overall health of patients with biliary atresia. PMID:23746866

    The pathophysiology of canine gallbladder diseases, including biliary sludge, gallbladder mucoceles and gallstones, is poorly understood. This study aimed to evaluate the component of gallbladder contents and bacterial infection of the gallbladder in order to elucidate the pathophysiology of biliary sludge and gallbladder mucoceles. A total of 43 samples of canine gallbladder contents (biliary sludge, 21 and gallbladder mucoceles, 22) were subjected to component analysis by infrared spectroscopy, and the resultant infrared spectra were compared with that of swine mucin. Of the 43 samples, 41 were also evaluated by aerobic and anaerobic bacterial culture. The contents of 20 (95.2%) biliary sludge and 22 (100%) gallbladder mucocele samples exhibited similar infrared spectra as swine mucin. Although biliary sludge and gallbladder mucocele contents exhibited similar infrared spectra, one sample of biliary sludge (4.8%) was determined to be composed of proteins. The rate of bacterial infection of the gallbladder was 10.0% for biliary sludge and 14.3% for gallbladder mucoceles. Almost all of the identified bacterial species were intestinal flora. These results indicate that the principal components of gallbladder contents in both gallbladder mucoceles and biliary sludge are mucins and that both pathophysiologies exhibit low rates of bacterial infection of the gallbladder. Therefore, it is possible that gallbladder mucoceles and biliary sludge have the same pathophysiology, and, rather than being independent diseases, they could possibly represent a continuous disease. Thus, biliary sludge could be considered as the stage preceding the appearance of gallbladder mucoceles. PMID:27990011

    Based on results of long-term follow-up and pathophysiologic considerations in 38 consecutive patients, it was possible to speculate on the frequencies of the various causes of the empty gallbladder syndrome. In approximate percentages, these are as follows: bile stasis causing chronic acalculous cholecystitis, 47%; physiologic dysfunction of the gallbladder, 24%; psychogenic illness, 16%; sphincter of Oddi dysfunction, 13%; ulcerative colitis, 3%. Because as many as 30% to 35% of these patients will not benefit from cholecystectomy, I feel that it should be undertaken with caution in cases of this syndrome. PMID:3716403

    Purpose Percutaneous biliary drainage (PBD) is used to relieve malignant bile duct obstruction (MBO) when endoscopic drainage is not feasible. Little is known about the effects of PBD on the quality of life (QoL) in patients with MBO. The aim of this study was to evaluate changes in QoL and pruritus after PBD and to explore the variables that impact these changes. Patients and Methods Eligible patients reported their QoL and pruritus before and after PBD using the Functional Assessment of Cancer Therapy – Hepatobiliary instrument (FACT-HS) and the Visual Analog Scale for Pruritus (VASP). Instruments were completed pre-procedure and at one and four weeks following PBD. Results One hundred and nine (60 male/49 female) patients enrolled, 102 (94%) had unresectable disease. PBD was technically successful (hepatic ducts cannulated at the conclusion of procedure) in all patients. There were two procedure-related deaths. All-cause mortality was 10% (N=11) at 4 weeks and 28% (N=31) at 8 weeks post PBD with a median survival of 4.74 months. The mean FACT-HS scores declined significantly (P<.01) over time (101.3, 94.8, 94.7 at baseline, 1 week, 4 weeks, respectively). The VASP scores showed significant improvement at 1 week with continued improvement at 4 weeks (P<.01). Conclusion PBD improves pruritus but not QoL in patients with MBO and advanced malignancy. There is high early mortality in this population. PMID:20358300

    The large animal model with benign biliary stricture (BBS) is essential to undergo experiment on developing new devices and endoscopic treatment. This study conducted to establish a clinically relevant porcine BBS model by means of endobiliary radiofrequency ablation (RFA). Endoscopic retrograde cholangiography (ERC) was performed on 12 swine. The animals were allocated to three groups (60, 80, and 100 W) according to the electrical power level of RFA electrode. Endobiliary RFA was applied to the common bile duct for 60 seconds using an RFA catheter that was endoscopically inserted. ERC was repeated two and four weeks, respectively, after the RFA to identify BBS. After the strictures were identified, histologic evaluations were performed. On the follow-up ERC two weeks after the procedure, a segmental bile duct stricture was observed in all animals. On microscopic examination, severe periductal fibrosis and luminal obliteration with transmural inflammation were demonstrated. Bile duct perforations occurred in two pigs (100 W, n = 1; 80 W, n = 1) but there were no major complications in the 60 W group. The application of endobiliary RFA with 60 W electrical power resulted in a safe and reproducible swine model of BBS. PMID:27510388

    2014-01-01

    Chondrodermatitis nodularis chronica helicis is a rare non-neoplastic inflammatory and degenerative process of the external ear, characterized by necrobiotic changes in the dermis that extend down to the perichondrium. This condition has been occasionally reported in patients with limited cutaneous systemic sclerosis but not in those with concomitant primary biliary cirrhosis; this association is known as Reynolds syndrome. We report a 70-year-old woman diagnosed with primary biliary cirrhosis at age 47 and with limited cutaneous systemic sclerosis at age 54 who developed a painful ulcerated nodule on the helical rim of the left ear shortly after the last diagnosis. The lesion was excised because of the suspicion of malignancy, but the histopathology was consistent with chondrodermatitis nodularis chronica helicis. Although this condition is infrequent, it is necessary to know, because it may occur in patients with systemic sclerosis and be mistaken for neoplasms, such as basal cell and squamous cell carcinoma, and these patients have an increased risk for the development of skin malignancies.

    Neuropathic pain is caused by a lesion or disease of the somatosensory system, including peripheral fibres (Aβ, Aδ and C fibres) and central neurons, and affects 7–10% of the general population. Multiple causes of neuropathic pain have been described and its incidence is likely to increase owing to the ageing global population, increased incidence of diabetes mellitus and improved survival from cancer after chemotherapy. Indeed, imbalances between excitatory and inhibitory somatosensory signalling, alterations in ion channels and variability in the way that pain messages are modulated in the central nervous system all have been implicated in neuropathic pain. The burden of chronic neuropathic pain seems to be related to the complexity of neuropathic symptoms, poor outcomes and difficult treatment decisions. Importantly, quality of life is impaired in patients with neuropathic pain owing to increased drug prescriptions and visits to health care providers, as well as the morbidity from the pain itself and the inciting disease. Despite challenges, progress in the understanding of the pathophysiology of neuropathic pain is spurring the development of new diagnostic procedures and personalized interventions, which emphasize the need for a multidisciplinary approach to the management of neuropathic pain.

  16. Primary Biliary Cirrhosis Is a Generalized Autoimmune Epithelitis

    PubMed Central

    2015-01-01

    Primary biliary cirrhosis (PBC) is a chronic progressive autoimmune cholestatic liver disease characterized by highly specific antimitochondrial antibodies (AMAs) and the specific immune-mediated injury of small intrahepatic bile ducts. Unique apoptotic feature of biliary epithelial cells (BECs) may contribute to apotope presentation to the immune system, causing unique tissue damage in PBC. Perpetuation of inflammation may result in senescence of BECs, contributing to irreversible loss of bile duct. In addition to the classic liver manifestations, focal inflammation and tissue damage are also seen in salivary glands and urinary tract in a significant proportion of PBC patients. These findings provide potent support to the idea that molecular mimicry may be involved in the breakdown of autoimmune tolerance and mucosal immunity may lead to a systematic epithelitis in PBC patients. Thus, PBC is considered a generalized epithelitis in clinical practice. PMID:25803105

    Formerly termed primary biliary cirrhosis, primary biliary cholangitis (PBC) is a chronic and progressive cholestatic liver disease characterized by the presence of antimitochondrial antibodies. Ursodeoxycholic acid (UDCA) therapy is the most effective and approved treatment for PBC and leads to a favorable outcome in the vast majority of cases. Although the etiology of PBC has not yet been elucidated, human leukocyte antigen (HLA) class II alleles have been consistently associated with disease onset for decades. Individuals in different geographic regions of the world may have varying susceptibility alleles that reflect indigenous triggering antigens. In this review, we describe the influence of HLA alleles and other gene polymorphisms on PBC along with the results of genome-wide association studies (GWAS) on this disease. PMID:28255561

    Biliary (hepatic and extrahepatic) intraductal papillary mucinous neoplasms and intraductal oncocytic papillary neoplasms/carcinoma are rare neoplasms. Classification of biliary intraductal papillary tumors can be confusing and reports in radiology literature are extremely limited. We describe the first reported case of biliary intraductal oncocytic papillary neoplasms/carcinoma in the liver in Australia. The intraductal nature of such neoplasms can be identified on magnetic resonance imaging and magnetic resonance cholangiopancreatography.

    We report a rare case of small bowel gallstone obstruction in a patient with cholecystointestinal fistula. Diagnosis of this condition is usually difficult and only achieved at surgery. We review the radiological findings, particularly the CT findings, helpful for diagnosis: ectopic gallstone, biliary gas and fistula. Early preoperative diagnosis could reduce morbidity and mortality. Treatment is surgical with enterolithotomy. There is some controversy over the need to repair the fistula.

    Peroral cholangioscopy (POC) is an important tool for the management of a selected group of biliary diseases. Because of its direct visualization, POC allows targeted diagnostic and therapeutic procedures. POC can be performed using a dedicated cholangioscope that is advanced through the accessory channel of a duodenoscope or via the insertion of a small-diameter endoscope directly into the bile duct. POC was first described in the 1970s, but the use of earlier generation devices was substantially limited by the cumbersome equipment setup and high repair costs. For nearly ten years, several technical improvements, including the single-operator system, high-quality images, the development of dedicated accessories and the increased size of the working channel, have led to increased diagnostic accuracy, thus assisting in the differentiation of benign and malignant intraductal lesions, targeting biopsies and the precise delineation of intraductal tumor spread before surgery. Furthermore, lithotripsy of difficult bile duct stones, ablative therapies for biliary malignancies and direct biliary drainage can be performed under POC control. Recent developments of new types of conventional POCs allow feasible, safe and effective procedures at reasonable costs. In the current review, we provide an updated overview of POC, focusing our attention on the main current clinical applications and on areas for future research. PMID:25992189

    Purpose: To evaluate the effect of adjuvant chemoradiotherapy (CRT) on locoregional control (LRC), disease-free survival (DFS), and overall survival (OS) for patients with extrahepatic biliary tract cancer treated with curative resection. Methods and Materials: The study involved 168 patients with extrahepatic biliary tract cancer undergoing curative resection between August 2001 and April 2009. Of the 168 patients, 115 received adjuvant CRT (CRT group) and 53 did not (no-CRT group). Gender, age, tumor size, histologic differentiation, pre- and postoperative carbohydrate antigen 19-9 level, resection margin, vascular invasion, perineural invasion, T stage, N stage, overall stage, and the use of adjuvant CRT were analyzed to identify the prognostic factors associated with LRC, DFS, and OS. Results: For all patients, the 5-year LRC, DFS, and OS rate was 54.8%, 30.6%, and 33.9%, respectively. On univariate analysis, the 5-year LRC, DFS, and OS rates in the CRT group were significantly better than those in the no-CRT group (58.5% vs. 44.4%, p = .007; 32.1% vs. 26.1%, p = .041; 36.5% vs. 28.2%, p = .049, respectively). Multivariate analysis revealed that adjuvant CRT was a significant independent prognostic factor for LRC, DFS, and OS (p < .05). Conclusion: Our results have suggested that adjuvant CRT helps achieve LRC and, consequently, improves DFS and OS in patients with extrahepatic biliary tract cancer.

  2. Pathogenesis of biliary atresia: defining biology to understand clinical phenotypes

    2016-01-01

    Biliary atresia is a severe cholangiopathy of early infancy that destroys extrahepatic bile ducts and disrupts bile flow. With a poorly defined disease pathogenesis, treatment consists of the surgical removal of duct remnants followed by hepatoportoenterostomy. Although this approach can improve the short-term outcome, the liver disease progresses to end-stage cirrhosis in most children. Further improvement in outcome will require a greater understanding of the mechanisms of biliary injury and fibrosis. Here, we review progress in the field, which has been fuelled by collaborative studies in larger patient cohorts and the development of cell culture and animal model systems to directly test hypotheses. Advances include the identification of phenotypic subgroups and stages of disease based on clinical, pathological and molecular features. Stronger evidence exists for viruses, toxins and gene sequence variations in the aetiology of biliary atresia, triggering a proinflammatory response that injures the duct epithelium and produces a rapidly progressive cholangiopathy. The immune response also activates the expression of type 2 cytokines that promote epithelial cell proliferation and extracellular matrix production by nonparenchymal cells. These advances provide insight into phenotype variability and might be relevant to the design of personalized trials to block progression of liver disease. PMID:26008129

    The evaluation of symptomatic patients who have undergone biliary enteric anastomoses, particularly when the diversion was into the jejunum, is difficult. Conventional techniques for evaluation, such as oral cholecystography (OCG), intravenous cholangiography (IVC), ultrasonography (US), computer-assisted tomography scanning (CT scanning), or endoscopy are not adequate to provide definitive information on the patency of the anastomoses. Hepatobiliary scintiscanning using /sup 99m/Tc-HIDA and BIDA (iminodiacetic acid derivatives) was performed on 12 patients. The patients were from 11 to 72 years of age and included ten men and two women. The scan results were correlated with US, CT scan, percutaneous transhepatic cholangiography (PTC), operative findings, and final diagnosis. Scanning was highly accurate in this group and could be performed successfully even in jaundiced patients (total serum bilirubin level up to 20.0 mg/dl). In patients in whom dilated bile ducts were demonstrated (by US, CT scan, or scintiscan), only the scintiscan revealed the true patency of the anastomoses. The advantages of the technique are that it is simple and noninvasive. Delayed transit of bile (scanning agent) to bowel is a very reliable indication of partial or complete obstruction. Scintiscanning is the only technique that demonstrated the functional state of biliary secretion and excretion into bowel in patients with previous biliary enteric anastomoses.

    1986-05-01

    Biliary excretion of benzo(a)pyrene (B(a)P) was investigated in rats, hamsters, and guinea pigs following intratracheal administration. (/sup 3/H)-B(a)P, in amounts of approximately 150 ng or 350 ..mu..g, was instilled into lungs and amounts of radioactivity excreted in bile were monitored for six hrs following administration. Differences in biliary excretion of (/sup 3/H)-B(a)P and/or metabolites among species were observed at low doses but not at high doses. Six hours after instillation of a low dose of B(a)P, 70, 54, and 62% of the dose was excreted in bile of rats, hamsters, and guinea pigs, respectively. Upon administration of the higher dose of B(a)P, approximately 50% of the dose was excreted in bile in six hrs by all species. Thus, rats and guinea pigs exhibit differences in biliary excretion of low and high doses of B(a)P whereas hamsters do not. Profiles of phase II metabolites in rats and hamsters were similar at both low and high doses, with the majority of metabolites being glucuronides and thioether conjugates. However, differences in relative amounts of these conjugates were observed between the two doses, with a shift towards a greater proportion of glucuronides at the higher dose. Metabolites in bile from guinea pigs were primarily thioether conjugates, which accounted for 88% of metabolites at the low dose and 95% at the high dose.

    Molecular weight (MW) is known as an important factor of biliary excretion in rats, guinea pigs, rabbits and humans. The objective of this study was to evaluate the relationship between the biliary excretion and MW of drugs in dogs. Data on the percentage of dose excreted into bile as parent drug (PD(b)) in dogs were collected from the literature for 134 compounds. Receiver operating characteristic (ROC) curve analysis was utilized to determine whether a MW threshold exists for PD(b). A MW threshold of 375-400 Da was established for anions in dogs, which is similar with the cutoff value observed in rats (400 Da) but lower than the one in humans (475 Da). No MW threshold was found for cations or cations/neutral compounds. A molecular volume threshold of 300A(3) was also determined for anions in dogs, which corresponds to a MW of 394 Da. In conclusion, our analysis suggested the presence of a MW cutoff for anions in dogs, which may be related with the molecular size of a compound. This represents the first report of the influence of MW or molecular volume as a determinant of biliary excretion for a structurally diverse set of compounds in dogs.

    Fifteen patients with malignant biliary obstruction from carcinoma of the bile ducts, gallbladder, and pancreas (Group I) or metastatic disease (Group II) were treated with intraluminal radiation therapy (ILRT) at Memorial Sloan-Kettering Cancer Center. In 11 cases ILRT was used as a central boost in combination with 3000 cGy external beam radiation therapy (ERT). No significant treatment toxicity was observed. Cholangiographic response was observed in 2 of 12 evaluable patients. In no patient was long-term relief of jaundice without indwelling biliary stent achieved. Survival from treatment in eight Group I patients treated with ILRT +/- ERT was 3 to 13 months (median, 4.5). Survival in seven similarly treated Group II patients was 0.5 to 8 months (median, 4.0). Additional data for ten similar patients referred for ILRT but treated with ERT alone are presented. Analysis of this and other reports indicate the need for prospective controlled trials of the role of this regimen in the management of malignant biliary obstruction before wider application can be recommended.

    Patients with non-resectable pancreatic and biliary tract cancer (cholangiocarcinoma and gallbladder cancer) have a dismal outlook with conventional palliative therapies, with a median survival of 3-9 months and a 5 year survival of less than 3%. Surgery is the only curative treatment but is appropriate in less than 20% of cases, and even then is associated with a 5-year survival of less than 30%. Although most applications of photodynamic therapy (PDT) in gastroenterology have been on lesions of the luminal gut, there is increasing experimental and clinical evidence for its efficacy in cancers of the pancreas and biliary tract. Our group has carried out the only clinical study of PDT in pancreatic carcinoma reported to date, and showed that PDT is feasible for local debulking of pancreatic cancer. PDT has also been used with palliative intent in patients with unresectable cholangiocarcinoma, with patients treated with stenting plus PDT reporting improvements in cholestasis, quality of life and survival compared with historical or randomized controls treated with stenting alone. Further controlled studies are needed to establish the influence of PDT and chemotherapy on the survival and quality of life of patients with pancreatic and biliary tract carcinoma.

    The diagnosis of ileus caused by biliary stones occurs very rarely, with the range of 2 % worldwide. This complication of cholecystolithiasis caused by the stone fistulation into gastrointestinal tract and its subsequent obstruction occurs mostly in elderly and has a high mortality rate. During the course of ten years (1996-2006) in the 2nd surgical clinic FNLP in Kosice, 1640 cholecystectomies and 255 operations, due to the obstruction ileus, were performed. Biliary ileus was recorded in four cases. In two cases, the reason being an obstruction caused by a travelled stone into jejunum, one event was caused by a mechanic wedge of a stone in duodenum and in the last event rectosigma was obturated. The diagnostic is relatively difficult because of a nonspecific symptomatology and often negative anamnesis of previous problems with gallstones. According to literature, the most reliable diagnostic method is computer tomography (CT). In our case, abdominal ultrasonography was successful, which pointed out this diagnosis. Gastroscopy localized the place of obstruction, but not its cause and X-ray image showed aerobilia two times. By the use of magnetic resonance cholangiopancreatography (MRCP) the diagnosis was not positively confirmed. Only in one out of four cases, there was a suspicion of the diagnosis of the biliary ileus, which makes its detectability 25%. The aim of this retrospective analysis is the comparison of diagnostic method-options and their range of success in the diagnosis of acute abdomen in our clinic and the entries in the world literature.

    Abstract Rationale: Von Hippel-Lindau (VHL) disease is a rare inherited, autosomal-dominant syndrome caused by heterozygous germline mutations in the VHL gene. VHL patients are prone to develop benign and malignant tumors and cysts in multiple organ systems involving kidneys, pancreas and central nervous system (CNS). The varied and complex clinical manifestations and radiological findings of VHL are of interest. Patient concerns: We report a 38-year-old woman with a ten-year history of VHL disease involving both pancreas and biliary system. To the best of our knowledge, direct involvement of the biliary system in VHL disease has never been reported. Diagnoses: The diagnosis was established via computed tomography scan and was confirmed by genetic testing. Interventions: The patient chose to receive conservative treatment and was followed up by magnetic resonance cholangiopancreatography and magnetic resonance imaging examination. Outcomes: Renal angiomas and cysts were found during follow-up and there were no evidence of malignant change of the pancreas and biliary system. Lessons: We described the first case of VHL-associated choledochal cysts and may present new visceral manifestations of VHL disease. Gastroenterologists should be aware of the clinical presentations of this rare disease for early detection of its life-threatening manifestations. PMID:28072736

  10. Apotopes and innate immune system: novel players in the primary biliary cirrhosis scenario.

    Our understanding of primary biliary cirrhosis has been rapidly growing over the past decade and the disease is now regarded as a model for other female-predominant, organ-specific autoimmune conditions. Primary biliary cirrhosis ensues from a multi-lineage loss of tolerance to the E2 component of the pyruvate dehydrogenase complex. One of the major unanswered questions in the pathogenesis of primary biliary cirrhosis is the specificity of small intrahepatic bile ducts attack while PDC-E2 is present in mitochondria of all nucleated cells. Recent findings suggest that the uniqueness of the primary target tissue, biliary epithelium, may be of considerable importance for understanding primary biliary cirrhosis and that the biliary epithelial cell is more than an innocent victim. Rather, it attracts an immune attack by virtue of the unique apoptotic mechanisms and by the way it handles PDC-E2. Moreover, recent evidence suggests that apoptotic bodies of biliary epithelial cell are able to activate the innate immune system in the presence of anti-mitochondrial antibodies. This review article is intended to provide a critical overview of the role of apoptosis in biliary epithelial cells, the activation of the innate immune system, and its biological and clinical significance in primary biliary cirrhosis.

    Two patients with pancreatic malignancies presented with biliary obstruction which could not be treated from an endoscopic approach. Standard transhepatic biliary drainage was relatively contraindicated because of moderate ascites and coagulopathy related to underlying liver disease. In one patient, a transjugular, transvenous approach was used to deliver a Wallstent endoprosthesis across the distal common bile duct obstruction in a single step procedure. In the second case, a previously placed biliary Wallstent was revised with an additional stent from a similar approach. Transjugular biliary catheterization offers a valuable alternative approach for primary stent placement or revision in patients with contraindication to standard transhepatic drainage.

    Mechanical obstruction of the biliary tree and resultant stasis are the cornerstone of a spectrum of diseases ranging from biliary colic to fulminant cholangitis. Infrequently acquired abnormalities of the abdominal vasculature can lead to biliary obstruction. In 2010, we reported a case of acute cholangitis resulting from compression of extra hepatic bile duct by an abdominal aortic aneurysm (AAA). We subsequently conducted a follow up scoping review of literature to identify other cases of acquired abdominal arterial abnormalities resulting in biliary obstruction looking at their management and outcomes. The articles were independently reviewed by two of the authors and pertinent data was extracted. The data was divided on an anatomic basis into two groups: one with primary aortic pathology and one with splanchnic vessel pathology. We identified 39 cases of biliary obstruction secondary to acquired aortic or splanchnic vessel abnormalities; 16 were caused by AAAs and 23 by splanchnic vessels. The cases were managed via conservative, endoscopic, endovascular or open surgical options based on the available technology and expertise. Although uncommon, recognition of aortic and splanchnic arterial abnormalities as a potential cause of biliary obstruction is important as management entails not only cautious decompression of the biliary tree but also addressing the underlying vascular pathology. We recommend that extrinsic biliary compression by an aneurysm or pseudoaneurysm be considered among the differential diagnosis in patients presenting with biliary obstruction and a known lesion of the abdominal vasculature.

    Background: Biliary brush cytology is the standard method of evaluating biliary strictures, but is insensitive at detecting malignancy. In pancreaticobiliary cancer minichromosome maintenance replication proteins (MCM 2–7) are dysregulated in the biliary epithelium and MCM5 levels are elevated in bile samples. This study aimed to validate an immunocolorimetric ELISA assay for MCM5 as a pancreaticobiliary cancer biomarker in biliary brush samples. Methods: Biliary brush specimens were collected prospectively at ERCP from patients with a biliary stricture. Collected samples were frozen at −80 °C. The supernatant was washed and lysed cells incubated with HRP-labelled anti-MCM5 mouse monoclonal antibody. Test positivity was determined by optical density absorbance. Patients underwent biliary brush cytology or additional investigations as per clinical routine. Results: Ninety-seven patients were included in the study; 50 had malignant strictures. Median age was 65 years (range 21–94) and 51 were male. Compared with final diagnosis the MCM5 assay had a sensitivity for malignancy of 65.4% compared with 25.0% for cytology. In the 72 patients with paired MCM5 assay and biliary brush cytology, MCM5 demonstrated an improved sensitivity (55.6% vs 25.0% P=0.0002) for the detection of malignancy. Conclusions: Minichromosome maintenance replication protein5 is a more sensitive indicator of pancreaticobiliary malignancy than standard biliary brush cytology. PMID:28081547

    External biliary drainage, the "routine" manner of terminating surgery on the common bile duct, should now become almost obsolete as new methods for operation and exploration during surgery are perfected. A review of cases receiving biliary surgery over a period of 20 years showed that external biliary drainage was conducted in only 4 p. cent of operations on the common bile duct (excluding biliodigestive anastomoses). External biliary drainage should be employed only after due reflection : trans-cystic drainage, the "minor" form, will be indicated less and less as investigational methods during operation develop, while Kehr's drain, the "major" form, will occupy a limited but necessary place in certain cases, primarily in angiocholitis.

    Objective To investigate the role(s) of Trps1 in non-anastomotic biliary stricture (NABS) following liver transplantation. Methods Immunohistochemical and histological techniques were used to detect Trps1, E-cadherin, CK19, vimentin, α-SMA, and collagen deposition. Human intrahepatic biliary epithelial cells (HIBECs) were infected with a Trps1 adenovirus, or transfected with Trps1 short-interfering RNAs (siRNAs). Reverse transcription polymerase chain reaction (RT-PCR) assays and western blotting were used to determine expression levels of epithelial and mesenchymal markers, and Trps1 in HIBECs. Results Expression of Trps1 and epithelial markers was down-regulated or absent in NABS liver samples. Mesenchymal markers were seen in biliary epithelial cells (BECs), with collagen deposited around the bile duct. Trps1 expression positively correlated with epithelial markers. Expression of epithelial marker mRNAs and proteins in HIBECs decreased with prolonged cold preservation (CP), while mesenchymal marker expression increased. A 12-h CP period led to increased Trps1 mRNA and protein levels. Expression of E-cadherin was increased in HIBECs following Trps1 adenovirus infection and CP/reperfusion injury (CPRI), with vimentin expression levels reduced and CPRI-mediated epithelial-mesenchymal transition (EMT) inhibited. Transfection of HIBECs with Trps1 siRNAs in conjunction with CPRI revealed that E-cadherin expression was decreased, vimentin expression was increased, and CPRI-mediated EMT was promoted. Conclusion Trps1 is involved in NABS pathogenesis following liver transplantation and negatively correlates with BEC EMT and biliary fibrosis in liver grafts. Trps1 demonstrates antagonistic effects that could reverse EMT. PMID:25886207

    Backgrounds/Aims Inflammatory mediators of the innate immune response play fundamental roles in the pathogenesis of acute pancreatitis. The correlation between interleukin-8 (IL-8) gene polymorphism with types of acute pancreatitis and severity of pancreatitis, was evaluated in this study. Methods According to the diagnostic criteria, 176 patients with acute pancreatitis were grouped into biliary (n=83) and nonbiliary pancreatitis (n=93). Healthy blood donors (n=100) served as controls. Serum alanine transaminase, aspartate transaminase, total and direct bilirubin, amylase, lypase, white blood cell count and c-reactive protein levels were evaluated to correlate with IL-8 rs4073 (-251T/A) polymorphism, which was analyzed using a real-time polymerase chain reaction method with melting point analysis. Results The IL-8 AA genotype was detected with a significantly higher frequency among the patients with acute biliary pancreatitis having higher alanine transaminase levels than the median range. Homozygote alleles were significantly higher among patients with acute biliary pancreatitis having amylase levels higher than the median range. Conclusions Determination of the frequency of IL-8 polymorphism in acute pancreatitis is informative and provides further evidence concerning the role of IL-8 in laboratory tests. PMID:28317043

    Among the clinically relevant pain conditions, pain in the musculoskeletal system is most frequent. This article reports extensive epidemiological data on musculoskeletal system pain in Germany and worldwide. Since back pain is most frequent, the diagnostics and therapeutic algorithms of acute, recurring, and chronic lower back pain in Germany will be particularly addressed. The importance of the physiologic-organic, the cognitive-emotional, the behavioral, and the social level to diagnostics and treatment will be discussed. We will also focus on osteoarthritic pain and address its epidemiology, clinical importance, and significance for the health care system. This article will list some reasons why the musculoskeletal system in particular is frequently the site of chronic pain. The authors believe that these reasons are to be sought in the complex structures of the musculoskeletal system; in the particular sensitivity of the deep somatic nociceptive system for long-term sensitization processes, as well as the ensuing nervous system reactions; and in the interactions between the nervous and immune systems. The article will give some insights into the research carried out on this topic in Germany.

  20. Fetal pain?

    Vanhatalo, S; van Nieuwenhuizen, O

    2000-05-01

    During the last few years a vivid debate, both scientifically and emotionally, has risen in the medical literature as to whether a fetus is able to feel pain during abortion or intrauterine surgery. This debate has mainly been inspired by the demonstration of various hormonal or motor reactions to noxious stimuli at very early stages of fetal development. The aims of this paper are to review the literature on development of the pain system in the fetus, and to speculate about the relationship between "sensing" as opposed to "feeling" pain and the number of reactions associated with painful stimuli. While a cortical processing of pain theoretically becomes possible after development of the thalamo-cortical connections in the 26th week of gestation, noxious stimuli may trigger complex reflex reactions much earlier. However, more important than possible painfulness is the fact that the noxious stimuli, by triggering stress responses, most likely affect the development of an individual at very early stages. Hence, it is not reasonable to speculate on the possible emotional experiences of pain in fetuses or premature babies. A clinically relevant aim is rather to avoid and/or treat any possibly noxious stimuli, and thereby prevent their potential adverse effects on the subsequent development.

    Although the significance of the enterohepatic circulation of bile salts in the solubilization and biliary excretion of cholesterol is well established, little is known about the intrahepatic determinants of biliary cholesterol output. Studies were undertaken to elucidate some of these determinants in the rat. Feeding 1% diosgenin for 1 wk increased biliary cholesterol output and saturation by 400%. Bile flow, biliary bile salt, phospholipid and protein outputs remained in the normal range. When ethynyl estradiol (EE) was injected into these animals, biliary cholesterol output decreased to almost normal levels under circumstances of minor changes in the rates of biliary bile salt and phospholipid outputs. Similarly, when chylomicron cholesterol was intravenously injected into diosgenin-fed animals, biliary cholesterol output significantly decreased as a function of the dose of chylomicron cholesterol administered. Relative rates of hepatic cholesterol synthesis and esterification were measured in isolated hepatocytes. Although hepatic cholesterogenesis increased 300% in diosgenin-fed animals, the contribution of newly synthesized cholesterol to total biliary cholesterol output was only 19 +/- 9%, compared with 12 +/- 6% in control and 15 +/- 5% in diosgenin-fed and EE-injected rats. The rate of oleate incorporation into hepatocytic cholesterol esters was 30% inhibited in diosgenin-fed rats. When EE was injected into these animals, the rate of cholesterol esterification increased to almost 300%. To investigate further the interrelationship between hepatic cholesterol esterification and biliary cholesterol output, we studied 21 diosgenin-fed rats. Six of them received in addition EE and 10 received chylomicron cholesterol. The relationships between biliary cholesterol output as a function of both microsomal acyl-CoA:cholesterol acyltransferase (ACAT) activity and hepatic cholesterol ester concentration were significantly correlated in a reciprocal manner.

    Abdominal pain can result from a variety of different intra- and extra-abdominal disorders. Given the wide variety of etiological triggers for this pain, the primary task during the first stage of the diagnostic work-up is to determine as soon as possible the underlying cause and the degree of emergency. The aim of this evaluation is to adapt the therapeutic measures which are necessary for a causal treatment to the individual situation. Contrary to somatic causes of abdominal pain, the availability of such a causal therapy for functional bowel disorders is still very limited. Given this dilemma, the therapeutic focus of abdominal pain associated with these functional syndromes has to be placed on symptom-oriented treatment.

    The fetus reacts to nociceptive stimulations through different motor, autonomic, vegetative, hormonal, and metabolic changes relatively early in the gestation period. With respect to the fact that the modulatory system does not yet exist, the first reactions are purely reflexive and without connection to the type of stimulus. While the fetal nervous system is able to react through protective reflexes to potentially harmful stimuli, there is no accurate evidence concerning pain sensations in this early period. Cortical processes occur only after thalamocortical connections and pathways have been completed at the 26th gestational week. Harmful (painful) stimuli, especially in fetuses have an adverse effect on the development of humans regardless of the processes in brain. Moreover, pain activates a number of subcortical mechanisms and a wide spectrum of stress responses influence the maturation of thalamocortical pathways and other cortical activation which are very important in pain processing.

    This article is part of a combined publication that expresses the current view of the European Society of Gastrointestinal Endoscopy about endoscopic biliary stenting. The present Clinical Guideline describes short-term and long-term results of biliary stenting depending on indications and stent models; it makes recommendations on when, how, and with which stent to perform biliary drainage in most common clinical settings, including in patients with a potentially resectable malignant biliary obstruction and in those who require palliative drainage of common bile duct or hilar strictures. Treatment of benign conditions (strictures related to chronic pancreatitis, liver transplantation, or cholecystectomy, and leaks and failed biliary stone extraction) and management of complications (including stent revision) are also discussed. A two-page executive summary of evidence statements and recommendations is provided. A separate Technology Review describes the models of biliary stents available and the stenting techniques, including advanced techniques such as insertion of multiple plastic stents, drainage of hilar strictures, retrieval of migrated stents and combined stenting in malignant biliary and duodenal obstructions.The target readership for the Clinical Guideline mostly includes digestive endoscopists, gastroenterologists, oncologists, radiologists, internists, and surgeons while the Technology Review should be most useful to endoscopists who perform biliary drainage.

    Biliary hyperplasia and liver fibrosis are common features in cholestatic liver disease. Melatonin is synthesized by the pineal gland as well as the liver. Melatonin inhibits biliary hyperplasia of bile duct-ligated (BDL) rats. Since melatonin synthesis (by the enzyme serotonin N-acetyltransferase, AANAT) from the pineal gland increases after dark exposure, we hypothesized that biliary hyperplasia and liver fibrosis are diminished by continuous darkness via increased melatonin synthesis from the pineal gland. Normal or BDL rats (immediately after surgery) were housed with light-dark cycles or complete dark for 1 wk before evaluation of 1) the expression of AANAT in the pineal gland and melatonin levels in pineal gland tissue supernatants and serum; 2) biliary proliferation and intrahepatic bile duct mass, liver histology, and serum chemistry; 3) secretin-stimulated ductal secretion (functional index of biliary growth); 4) collagen deposition, liver fibrosis markers in liver sections, total liver, and cholangiocytes; and 5) expression of clock genes in cholangiocytes. In BDL rats exposed to dark there was 1) enhanced AANAT expression/melatonin secretion in pineal gland and melatonin serum levels; 2) improved liver morphology, serum chemistry and decreased biliary proliferation and secretin-stimulated choleresis; and 4) decreased fibrosis and expression of fibrosis markers in liver sections, total liver and cholangiocytes and reduced biliary expression of the clock genes PER1, BMAL1, CLOCK, and Cry1. Thus prolonged dark exposure may be a beneficial noninvasive therapeutic approach for the management of biliary disorders.

    The biliary duct is an extremely rare site for colon cancer metastasis. It often leads to a diagnostic dilemma, since primary cholangiocarcinoma (potentially treatable with surgery) has a similar presentation. This paper highlights our experience with 5 consecutive patients who had colon malignancy with biliary metastasis, and prognosis of their disease. Five patients, with a history of primary colon cancer since 2010, were identified to have biliary metastasis. Of these, 4 (80.0%) patients were male. The median time to diagnosis of biliary metastasis from diagnosis of colon cancer was 59.2 months (0-70.1 months), and all exhibited symptoms of biliary obstruction or its associated complications. Evaluation of the tumour samples revealed all specimens to be negative for CK7 but positive for CK20, suggestive of a colorectal primary. The median survival of the 5 patients was 23.5 months (1.8-44.5 months) from the diagnosis of biliary metastasis. However, none of their death was related to the direct complication of biliary obstruction. Biliary metastasis is a rare entity for metastatic colon malignancy. Diagnosis may be difficult radiologically, and immunohistochemical staining may help in identification. The overall survival for these patients is dismal. PMID:28317047

    Backgrounds/Aims Despite hepatolithiasis being a risk factor for biliary neoplasm including cholangiocarcinoma, the incidence of underlying biliary neoplasm is unknown in patients with preoperative benign hepatolithiasis. The aim of this study was to evaluate the incidence of underlying biliary neoplasm in patients who underwent major hepatectomy for preoperative benign hepatolithiasis. Methods Between March 2005 and December 2015, 73 patients who underwent major hepatectomy for preoperative benign hepatolithiasis were enrolled in this study. The incidence and pathological differentiation of concomitant biliary neoplasm were retrospectively determined by review of medical records. Postoperative complications after major hepatectomy were evaluated. Results Concomitant biliary neoplasm was pathologically confirmed in 20 patients (27.4%). Biliary intraepithelial neoplasia (BIN) was detected in 12 patients (16.4%), and 1 patient (1.4%) had intraductal papillary mucinous neoplasm (IPMN), as the premalignant lesion. Cholangiocarcinoma was pathologically confirmed in 7 patients (9.6%). Preoperative imaging of the 73 patients revealed biliary stricture at the first branch of bile duct in 31 patients (42.5%), and at the second branch of bile duct in 39 patients (53.4%). Postoperative complications developed in 14 patients (19.1%). Almost all patients recovered from complications, including intra-abdominal abscess (9.6%), bile leakage (4.1%), pleural effusion (2.7%), and wound infection (1.4%). Only 1 patient (1.4%) died from aspiration pneumonia. Conclusions The incidence of underlying biliary neoplasm was not negligible in the patients with hepatolithiasis, despite meticulous preoperative evaluations. PMID:28261696

    Symptomatic biliary stricture causes life-threatening complications, such as jaundice, recurrent cholangitis and secondary biliary cirrhosis. Fully covered self-expanding metal stents (FCSEMSs) are gaining acceptance for treatments of benign biliary stricture and palliative management of malignant biliary obstructions. However, the high rate of FCSEMS obstruction limits their clinic use. In this study, we developed a novel biliary stent coated with silver nanoparticles (AgNPs) and investigated its efficacy both in vitro and in vivo. We first identified properties of the AgNP complex using ultraviolet detection. The AgNP complex was stable without AgNP agglomeration, and Ag abundance was correspondingly increased with an increased bilayer number. The AgNP biliary stent demonstrated good performance in the spin-assembly method based on topographic observation. The AgNP biliary stent also exhibited a long-term anti-coagulation effect and a slow process of Ag+ release. In vitro anti-bacteria experiments indicated that the AgNP biliary stent exhibited high-efficiency anti-bacterial activity for both short- and long-term periods. Importantly, application of the AgNP biliary stent significantly prolonged the unobstructed period of the biliary system and improved survival in preclinical studies as a result of its anti-microbial activity and decreased granular tissue formation on the surface of the anastomotic biliary, providing a novel and effective treatment strategy for symptomatic biliary strictures.

    Effective management of procedural and postoperative pain in neonates is required to minimize acute physiological and behavioral distress and may also improve acute and long-term outcomes. Painful stimuli activate nociceptive pathways, from the periphery to the cortex, in neonates and behavioral responses form the basis for validated pain assessment tools. However, there is an increasing awareness of the need to not only reduce acute behavioral responses to pain in neonates, but also to protect the developing nervous system from persistent sensitization of pain pathways and potential damaging effects of altered neural activity on central nervous system development. Analgesic requirements are influenced by age-related changes in both pharmacokinetic and pharmacodynamic response, and increasing data are available to guide safe and effective dosing with opioids and paracetamol. Regional analgesic techniques provide effective perioperative analgesia, but higher complication rates in neonates emphasize the importance of monitoring and choice of the most appropriate drug and dose. There have been significant improvements in the understanding and management of neonatal pain, but additional research evidence will further reduce the need to extrapolate data from older age groups. Translation into improved clinical care will continue to depend on an integrated approach to implementation that encompasses assessment and titration against individual response, education and training, and audit and feedback.

    The benefit of placing a T-tube for duct-to-duct biliary reconstruction during orthotopic liver transplantation (OLT) remains controversial because it could be associated with specific complications, especially at the time of T-tube removal. While the utility of T-tube during OLT represents an eternal debate, only a few technical refinements of T-tube placement have been described since the report of the original technique by Starzl and colleagues. Herein, we present a novel technique of T-tube placement for duct-to-duct biliary reconstruction during OLT, using a tunneled retroperitoneal route. On the basis of our experience of 305 patients who benefitted from the reported technique, the placement of a tunneled retroperitoneal biliary T-tube appears to be safe and results in a low rate of biliary complications, especially at the time of T-tube removal.

    Abstract Background: In patients with inoperable malignant biliary strictures, endoscopic retrograde cholangiopancreatography (ERCP) guided biliary stenting fails in 5% to 10% patients due to difficult anatomy/inability to cannulate the papilla. Recently, endoscopic ultrasound guided biliary drainage (EUS-BD) has been described. Primary outcomes were to evaluate the biliary drainage success rates with EUS and compare it to percutaneous transhepatic biliary drainage (PTBD). Secondary outcomes were to evaluate overall procedure related complications. Methods: Study selection criteria: Studies evaluating the efficacy of EUS-BD and comparing EUS-BD versus PTBD in inoperable malignant biliary stricture patients with a failed ERCP were included in this analysis. Data collection and extraction: Articles were searched in Medline, PubMed, and Ovid journals. Two authors independently searched and extracted data. The study design was written in accordance to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Subgroup analyses of prospective studies and EUS-BD versus PTBD were performed. Statistical method: Pooled proportions were calculated using fixed and random effects model. I2 statistic was used to assess heterogeneity among studies. Results: Initial search identified 846 reference articles, of which 124 were selected and reviewed. Sixteen studies (N = 528) that met the inclusion criteria were included in this analysis. In the pooled patient population, the percentage of patients that had a successful biliary drainage with EUS was 90.91% (95% CI = 88.10–93.38). The proportion of patients that had overall procedure related complications with EUS-PD was 16.46% (95% CI = 13.20–20.01). The pooled odds ratio for successful biliary drainage in EUS-PD versus PTBD group was 3.06 (95% CI = 1.11–8.43). The risk difference for overall procedure related complications in EUS-PD versus PTBD group was −0.21 (95% CI = −0

    A 31 year-old patient presented with a retention jaundice from a centrally located hepatoma invading the hilum. Because of the patient's age and the severity of the pruritus and jaundice, palliative treatment was performed by percutaneous catheterization of the intrahepatic biliary tracts to drain the right and left hepatic canals. As the hilar stenosis could not be overcome, the external drainage was transformed into internal drainage by implantation of a Kron's biliary prosthesis linking the intrahepatic biliary tracts, following segment III hepatotomy, to the duodenal lumen, with burying of the prosthesis in the gastric antrum region. Jaundice was reduced until death of the patients from metastases 6 months later. This case demonstrates that the use of Kron's biliary prosthesis to perform a biliodigestive shunt from intrahepatic biliary pathways is a valid palliative procedure in patients with limited life expectancies.

    The clinical outcome of patients receiving liver transplantation could be significantly affected by biliary complications, including strictures, leaks, stones and bilomas; early diagnosis and treatment of these conditions lead to markedly reduction in morbidity and mortality. Therapeutic gold standard is represented by conservative approaches, both endoscopic and percutaneous, based on the type of biliary reconstruction, the local availability of the procedures and specific expertise. In patients with previous transplantation, the difficult biliary access and the possible presence of concomitant complications (mainly strictures) further restrict the efficacy of the endoscopic and percutaneous treatments; on the other hand, surgery should generally be avoided because of the even increased morbidity and mortality due to technical and clinical issues. Here we review the most common biliary complications occurring after liver transplantation and discuss available treatment options including future perspectives such as endoscopic ultrasound-guided biliary access in patients with Roux-en-Y choledocho-jejunostomy or extracorporeal shock wave lithotripsy for difficult stones.

    Here, we report our experience with a case of severe biliary bleeding due to a hepatic arterial pseudoaneurysm that had developed 1 year after endoscopic biliary plastic stent insertion. The patient, a 78-year-old woman, presented with hematemesis and obstructive jaundice. Ruptured hepatic arterial pseudoaneurysm was diagnosed, which was suspected to have been caused by long-term placement of an endoscopic retrograde biliary drainage (ERBD) stent. This episode of biliary bleeding was successfully treated by transarterial embolization (TAE). Pseudoaneurysm leading to hemobilia is a rare but potentially fatal complication in patients with long-term placement of ERBD. TAE is a minimally invasive procedure that offers effective treatment for biliary bleeding. PMID:28216982

    Extrahepatic biliary obstruction leads to bile duct epithelial cell proliferation. Somatostatin and its analogue, octreotide, have been shown to inhibit DNA synthesis and proliferation in hepatocytes. We investigated the effect of octreotide on the biliary epithelial cell proliferative responses to biliary obstruction. Male Sprague-Dawley rats underwent common bile duct ligation and subcutaneous injection of either saline or octreotide (6 micrograms/kg) twice daily for 7 days. Morphometric analysis of hepatocytes, bile duct epithelial cells, and periportal connective tissue was performed by computerized point counting. Hepatocyte volume was preserved with octreotide treatment, which also significantly decreased bile duct proliferation and periportal extracellular matrix deposition in response to biliary obstruction compared with saline treated, duct-ligated animals. These results indicate that octreotide prevents the morphological changes that accompany extrahepatic biliary obstruction. Images Figure 1 PMID:8256850

  12. The immunobiology and pathophysiology of primary biliary cirrhosis.

    Hirschfield, Gideon M; Gershwin, M Eric

    2013-01-24

    Primary biliary cirrhosis (PBC) is an autoimmune disease characterized by clinical homogeneity among patients, an overwhelming female predominance, production of a multilineage immune response to mitochondrial autoantigens, inflammation of small bile ducts, and in some patients the development of fibrosis and cirrhosis. The targets in this disease are small bile ducts, and the prototypic serologic response includes antimitochondrial antibodies (AMAs). Several key observations have greatly advanced our understanding of PBC. First, the multilineage immune response, including AMAs, is directed at the E2 component of the 2-oxo-dehydrogenase pathway, particularly PDC-E2. Second, such autoantibodies may be identified years before the clinical diagnosis of disease. Third, the autoreactive T cell precursor frequency for both CD4 and CD8 cells is significantly higher in liver and regional lymph node than in blood, so the multilineage antimitochondrial response may be required for the development of this disease. Fourth, the apotope of biliary cells contains intact PDC-E2; this apotope, in a setting that includes granulocyte macrophage colony-stimulating factor-stimulated macrophages and AMAs, produces an intense proinflammatory response. Fifth, several mouse models of PBC highlight the importance of loss of tolerance to PDC-E2 as well as a critical role for the interleukin (IL)-12 signaling pathway. Finally, genome-wide association studies suggest an important role for the IL-12 pathway in disease susceptibility. Taken together, these findings have resulted in a better understanding of the mechanism for selective biliary cell destruction and have also suggested unique pathways for therapeutic intervention.

  13. Imaging tests for accurate diagnosis of acute biliary pancreatitis.

    2014-11-28

    Gallstones represent the most frequent aetiology of acute pancreatitis in many statistics all over the world, estimated between 40%-60%. Accurate diagnosis of acute biliary pancreatitis (ABP) is of outmost importance because clearance of lithiasis [gallbladder and common bile duct (CBD)] rules out recurrences. Confirmation of biliary lithiasis is done by imaging. The sensitivity of the ultrasonography (US) in the detection of gallstones is over 95% in uncomplicated cases, but in ABP, sensitivity for gallstone detection is lower, being less than 80% due to the ileus and bowel distension. Sensitivity of transabdominal ultrasonography (TUS) for choledocolithiasis varies between 50%-80%, but the specificity is high, reaching 95%. Diameter of the bile duct may be orientative for diagnosis. Endoscopic ultrasonography (EUS) seems to be a more effective tool to diagnose ABP rather than endoscopic retrograde cholangiopancreatography (ERCP), which should be performed only for therapeutic purposes. As the sensitivity and specificity of computerized tomography are lower as compared to state-of-the-art magnetic resonance cholangiopancreatography (MRCP) or EUS, especially for small stones and small diameter of CBD, the later techniques are nowadays preferred for the evaluation of ABP patients. ERCP has the highest accuracy for the diagnosis of choledocholithiasis and is used as a reference standard in many studies, especially after sphincterotomy and balloon extraction of CBD stones. Laparoscopic ultrasonography is a useful tool for the intraoperative diagnosis of choledocholithiasis. Routine exploration of the CBD in cases of patients scheduled for cholecystectomy after an attack of ABP was not proven useful. A significant rate of the so-called idiopathic pancreatitis is actually caused by microlithiasis and/or biliary sludge. In conclusion, the general algorithm for CBD stone detection starts with anamnesis, serum biochemistry and then TUS, followed by EUS or MRCP. In the end

The study was realised in the Surgical Department of the Districtual Hospital Baia Mare between 27.04.1997-27.04.1999, which means the precursory year of beginning laparoscopic surgery and the first year with experience in laparoscopic surgery. The conclusions of this study prove that the number of reinterventions after laparoscopic surgery is less than after classic surgery of biliary ducts.

    Ursodeoxycholic acid is considered as first line treatment in patients with primary biliary cirrhosis. Its mechanism of action in this disease is unknown and there is controversy about its clinical impact. Searching in Epistemonikos database, which is maintained by screening 19 databases, we identified four systematic reviews including 16 studies. We combined the evidence using tables with summary of findings following the GRADE approach and concluded ursodeoxycholic acid may not have any effect on pruritus, and there is uncertainty about its effect on mortality, need for liver transplantation or on any other important outcome for the patient.

    Despite advances in surgical techniques, benign biliary strictures after living donor liver transplantation (LDLT) remain a significant biliary complication and play an important role in graft and patient survival. Benign biliary strictures after transplantation are classified into anastomotic or non-anastomotic strictures. These two types differ in presentation, outcome, and response to therapy. The leading causes of biliary strictures include impaired blood supply, technical errors during surgery, and biliary anomalies. Because patients usually have non-specific symptoms, a high index of suspicion should be maintained. Magnetic resonance cholangiography has gained widespread acceptance as a reliable noninvasive tool for detecting biliary complications. Endoscopy has played an increasingly prominent role in the diagnosis and treatment of biliary strictures after LDLT. Endoscopic management in LDLT recipients may be more challenging than in deceased donor liver transplantation patients because of the complex nature of the duct-to-duct reconstruction. Repeated aggressive endoscopic treatment with dilation and the placement of multiple plastic stents is considered the first-line treatment for biliary strictures. Percutaneous and surgical treatments are now reserved for patients for whom endoscopic management fails and for those with multiple, inaccessible intrahepatic strictures or Roux-en-Y anastomoses. Recent advances in enteroscopy enable treatment, even in these latter cases. Direct cholangioscopy, another advanced form of endoscopy, allows direct visualization of the inner wall of the biliary tree and is expected to facilitate stenting or stone extraction. Rendezvous techniques can be a good option when the endoscopic approach to the biliary stricture is unfeasible. These developments have resulted in almost all patients being managed by the endoscopic approach. PMID:26819525

    The paper studies the combined radiologic and endoscopic approach (rendez vous technique) to the treatment of the biliary complications following liver transplant. The “rendez-vous” technique was used with an electrokinetic lithotripter, in the treatment of a biliary anastomotic stricture with multiple biliary stones in a patient who underwent orthotopic liver transplant. In this patient, endoscopic or percutaneous transhepatic management of the biliary complication failed. The combined approach, percutaneous transhepatic and endoscopic treatment (rendez-vous technique) with the use of an electrokinetic lithotritor, was used to solve the biliary stenosis and to remove the stones. Technical success, defined as disappearance of the biliary stenosis and stone removal, was obtained in just one session, which definitively solved the complications. The combined approach of percutaneous transhepatic and endoscopic (rendez-vous technique) treatment, in association with an electrokinetic lithotritor, is a safe and feasible alternative treatment, especially after the failure of endoscopic and/or percutaneous trans-hepatic isolated procedures.

    Sera from patients with primary biliary cirrhosis (PBC) react with enzymes of the 2-oxo dehydrogenase pathways, particularly PDC-E2. These enzymes are present in all nucleated cells, yet autoimmune damage is confined to biliary epithelial cells. Using a panel of eight mouse monoclonal antibodies and a human combinatorial antibody specific for PDC-E2, we examined by indirect immunofluorescence and confocal microscopy sections of liver from patients with PBC, progressive sclerosing cholangitis, and hepatocarcinoma. The monoclonal antibodies gave typical mitochondrial immunofluorescence on biliary epithelium and on hepatocytes from patients with either PBC, progressive sclerosing cholangitis, or hepatocarcinoma. However, one of eight mouse monoclonal antibodies (C355.1) and the human combinatorial antibody reacted with great intensity and specificity with the luminal region of biliary epithelial cells from patients with PBC. Simultaneous examination of these sections with an antiisotype reagent for human IgA revealed high IgA staining in the luminal region of biliary epithelial cells in patients with PBC. IgG and IgA antibodies to PDC-E2 were detected in the bile of patients with PBC but not normal controls. We believe that this data may be interpreted as indicating that a molecule cross-reactive with PDC-E2 is expressed at high levels in the luminal region of biliary epithelial cells in PBC.

    Biliary atresia (BA) is thought to be associated with infections by viruses such as Reoviridae and is characterized histologically by fibrosclerosing cholangitis with proinflammatory cytokine-mediated inflammation. Interleukin (IL)-32 affects the continuous inflammation by increasing the production of proinflammatory cytokines. In this study, the role of IL-32 in the cholangitis of BA was examined. Immunohistochemistry for IL-32 and caspase 1 was performed using 21 samples of extrahepatic bile ducts resected from BA patients. Moreover, using cultured human biliary epithelial cells (BECs), the expression of IL-32 and its induction on stimulation with a Toll-like receptor [(TLR)-3 ligand (poly(I:C)] and proinflammatory cytokines was examined. BECs composing extrahepatic bile ducts showing cholangitis expressed IL-32 in BA, but not in controls. Caspase 1 was expressed constantly on BECs of both BA and control subjects. Furthermore, poly(I:C) and proinflammatory cytokines [(IL-1β, interferon (IFN)-γ and tumour necrosis factor (TNF)-α] induced IL-32 expression strongly in cultured BECs, accompanying the constant expression of TLR-3 and caspase 1. Our results imply that the expression of IL-32 in BECs was found in the damaged bile ducts of BA and induced by biliary innate immunity via TLR-3 and proinflammatory cytokines. These findings suggest that IL-32 is involved initially in the pathogenic mechanisms of cholangitis in BA and also plays an important role in the amplification and continuance of periductal inflammatory reactions. It is therefore tempting to speculate that inhibitors of IL-32 could be useful for attenuating cholangitis in BA.

    Experimental models of autoimmune diseases have led to the conclusion that an immune response to nuclear antigens is a sentinel marker for loss of tolerance and potential tissue damage. Various proteins are targets of antinuclear antibodies in a variety of autoimmune diseases, ranging from systemic rheumatologic disorders to diseases affecting specific organs such as the liver. Autoantibodies against specific nuclear constituents have also been used as probes to understand the structure and the function of the targeted components and their relevance to disease pathogenesis. Approximately a quarter of patients with primary biliary cirrhosis (PBC) have antibodies targeting proteins of the nuclear pore complex (NPC), a multi-protein structure that mediates molecular transport across the nuclear envelope. Autoantibodies against the integral membrane glycoprotein gp210 and nucleoporin p62 appear to be highly specific for PBC, an autoimmune disease characterized by progressive destruction of intrahepatic biliary epithelial cells. This review discusses the diagnostic and clinical relevance of anti-NPC antibodies in PBC and the possibility that this autoimmune response may arise as a result of molecular mimicry. PMID:22487189

    Examination was made of the urinary and biliary excretion of metabolites of daidzin and daidzein, the major components of roots of Pueraria lobata Ohwi (Leguminosae) in rats. The urine of rats administered daidzin orally contained four major metabolites, daidzein 7,4'-di-O-sulfate (M-1), daidzein 7-O-beta-D-glucuronide (M-2), daidzein 4'-O-sulfate (M-3), daidzein (M-4), as determined from spectroscopic and chemical data. The urine of rats treated with daidzein contained M-2--M-4 in the above metabolites. Total cumulative amounts of the four metabolites excreted in the urine at 48 h following the oral administration of daidzin and daidzein were approximately 4.8% and 4.6% of the doses administered, respectively. The bile of rats administered daidzin orally contained M-1--M-4. Daidzein 7-O-beta-D-glucuronide 4'-O-sulfate (M-5), a major biliary metabolite, was identified by the high-performance liquid chromatography (HPLC), liquid chromatography-mass spectrometry (LC-MS) and nuclear magnetic resonance (NMR) spectra. At least daidzin appeared to be hydrolyzed to aglycone after absorption in the body, and as a part of metabolites, M-1--M-4 having free hydroxyl, glucuronided or sulfated hydroxyls at the C-7 position, may then be excreted in the urine and bile.

    We analyze our experience with the management of biliary strictures (BSs) in 27 pediatric patients who underwent liver transplantation with the diagnosis of BS. Mean recipient age was 38 months (range, 2.5-182 months). In all patients percutaneous transhepatic cholangiography, biliary catheter placement, and bilioplasty were performed. In 20 patients the stenoses were judged resolved by percutaneous balloon dilatation and the catheters removed. Mean number of balloon dilatations performed was 4.1 (range, 3-6). No major complications occurred. All 20 patients are symptom-free with respect to BS at a mean follow-up of 13 months (range, 2-46 months). In 15 of 20 patients (75%) one course of percutaneous stenting and bilioplasty was performed, with no evidence of recurrence of BS at a mean follow-up of 15 months (range, 2-46 months). In 4 of 20 patients (20%) two courses of percutaneous stenting and bilioplasty were performed; the mean time to recurrence was 9.8 months (range, 2.4-24 months). There was no evidence of recurrence of BS at a mean follow-up of 12 months (range, 2-16 months). In 1 of 20 patients (5%) three courses of percutaneous stenting and bilioplasty were performed; there was no evidence of recurrence of BS at a mean follow-up of 10 months. In conclusion, BS is a major problem following pediatric liver transplantation. Radiological percutaneous treatment is safe and effective, avoiding, in most cases, surgical revision of the anastomosis.

    Primary biliary cirrhosis (PBC) is an autoimmune disease of the liver, characterized by the presence of antimitochondrial antibodies (AMA) and progressive immune-mediated destruction of biliary ductules, which lead to cirrhosis. Theories of the PBC etiopathogenesis assume that the disease develops secondarily as an improper immunological reaction to undefined environmental and/or infectious factors in genetically predisposed individuals. Ursodeoxycholic acid (UDCA) is the only drug recommended to treat PBC; it delays the progression of liver disease, but remains only a symptomatic treatment. In the advanced stage of PBC, the treatment of choice is liver transplantation (LTx). Nowadays, PBC is the third indication for LTx, after viral-related and alcoholic liver cirrhosis. Unfortunately, PBC recurs in 21-37% of patients at 10 years after LTx, and in 43% at 15 years after LTx, with the median time to recurrence of 3-5.5 years. Diagnosis of recurrent PBC (rPBC) is based on the liver histopathology. Although various risk factors of rPBC have been investigated, the cause of the recurrence is not clear. There is no specific treatment of rPBC. Together with immunosuppression after LTx, UDCA remains the treatment of choice. New diagnostic technologies (e.g., genomics, proteomics, cell-based therapy, and clinical study of the rPBC patients) may be helpful in understanding the pathogenesis of PBC and the development of new treatment modalities.

    Single-incision laparoscopic surgery (SILS), or laparoendoscopic single-site surgery, has been employed in various fields to minimize traumatic effects over the last two decades. Single-incision laparoscopic cholecystectomy (SILC) has been the most frequently studied SILS to date. Hundreds of studies on SILC have failed to present conclusive results. Most randomized controlled trials (RCTs) have been small in scale and have been conducted under ideal operative conditions. The role of SILC in complicated scenarios remains uncertain. As common bile duct exploration (CBDE) methods have been used for more than one hundred years, laparoscopic CBDE (LCBDE) has emerged as an effective, demanding, and infrequent technique employed during the laparoscopic era. Likewise, laparoscopic biliary-enteric anastomosis is difficult to carry out, with only a few studies have been published on the approach. The application of SILS to CBDE and biliary-enteric anastomosis is extremely rare, and such innovative procedures are only carried out by a number of specialized groups across the globe. Herein we present a thorough and detailed analysis of SILC in terms of operative techniques, training and learning curves, safety and efficacy levels, recovery trends, and costs by reviewing RCTs conducted over the past three years and two recently updated meta-analyses. All existing literature on single-incision LCBDE and single-incision laparoscopic hepaticojejunostomy has been reviewed to describe these two demanding techniques. PMID:26811621

  9. Kron's biliary prosthetic bypass in the treatment of neoplastic jaundice.

    1985-01-01

    After experimental study in the dog, which showed the material to be highly reliable, an original method of biliary bypass using a silicone prosthesis in the treatment of neoplastic jaundice is introduced. This prosthesis allows the bile duct to be bypassed regardless of the location of the obstacle. This method was used in 150 patients; recession was sufficiently good in 84 of them to confirm good tolerance and the excellence of the results. In fact, good results were recorded in 95% of cases of cancer of the hilum, which is all the more remarkable in consideration of the difficulties involved in these operations. The main postoperative complications are bile fistulas which resolve spontaneously if the precaution of extensively draining the zones of intubation is taken; postoperative comfort is excellent; no constraint is necessary and the operative risk is moderate, this is particularly desirable in patients in a poor general condition. A short prosthesis makes transtumoral intubation possible, and a long prosthesis allows implantation in the digestive tract: stomach, duodenum or first intestinal loop. Postoperative persistence of jaundice is rare if a prosthesis of sufficient diameter is used and if no major bile duct or part of the liver is excluded. Cholangitis is exceptional and indicative of an excluded biliary area.

    Biliary tract cancers (BTCs) are characterized by a bad prognosis and the armamentarium of drugs for their treatment is very poor. Although the inflammatory status of biliary tract represents the first step in the cancerogenesis, the microenvironment also plays a key role in the pathogenesis of BTCs, promoting tumor angiogenesis, invasion and metastasis. Several molecules, such as vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF), are involved in the angiogenesis process and their expression on tumor samples has been explored as prognostic marker in both cholangiocarcinoma and gallbladder cancer. Recent studies evaluated the genomic landscape of BTCs and evidenced that aberrations in several genes enrolled in the pro-angiogenic signaling, such as FGF receptor-2 (FGFR-2), are characteristic of BTCs. New drugs targeting the signaling pathways involved in angiogenesis have been tested in preclinical studies both in vitro and in vivo with promising results. Moreover, several clinical studies tested monoclonal antibodies against VEGF and tyrosine kinase inhibitors targeting the VEGF and the MEK/ERK pathways. Herein, we evaluate both the pathogenic mechanisms of BTCs focused on angiogenesis and the preclinical and clinical data available regarding the use of new anti-angiogenic drugs in these malignancies.

    2015-01-01

    Biliary atresia (BA) is a progressive, inflammatory, and fibrosclerosing cholangiopathy in infants that results in obstruction of both extrahepatic and intrahepatic bile ducts. It is the most common cause for pediatric liver transplantation. In contrast, the sea lamprey undergoes developmental BA with transient cholestasis and fibrosis during metamorphosis, but emerges as a fecund adult with steatohepatitis and fibrosis in the liver. In this paper, we present new histological evidence and compare the sea lamprey to existing animal models to highlight the advantages and possible limitations of using the sea lamprey to study the etiology and compensatory mechanisms of BA and other liver diseases. Understanding the signaling factors and genetic networks underlying lamprey BA can provide insights into BA etiology and possible targets to prevent biliary degeneration and to clear fibrosis. In addition, information from lamprey BA can be used to develop adjunct treatments for patients awaiting or receiving surgical treatments. Furthermore, the cholestatic adult lamprey has unique adaptive mechanisms that can be used to explore potential treatments for cholestasis and nonalcoholic steatohepatitis (NASH). PMID:26101777

    Biliary tract cancers (BTCs) are a group of highly aggressive malignant tumors with a poor prognosis. The current diagnosis is based mainly on imaging and intraoperative exploration due to brush cytology havinga low sensitivity and the standard markers, such as carcinoembryonic antigen (CEA) and carbohydrate 19-9 (CA19-9), not having enough sensitivity nor specificity to be used in a differential diagnosis and early stage detection. Thus, better non-invasive methods that can distinguish between normal and pathological tissue are needed. MicroRNAs (miRNAs) are small, single-stranded non-coding RNA molecules of ~20-22 nucleotides that regulate relevant physiological mechanisms and can also be involved in carcinogenesis. Recent studies have demonstrated that miRNAs are detectable in multiple body fluids, showing great stability, either free or trapped in circulating microvesicles, such as exosomes. miRNAs are ideal biomarkers that may be used in screening and prognosis in biliary tract cancers, aiding also in the clinical decisions at different stages of cancer treatment. This review highlights the progress in the analysis of circulating miRNAs in serum, plasma and bile as potential diagnostic and prognostic markers of BTCs.

    Background There is increasing interest in the microbiome of the hepatobiliary system. This study investigated the influence of infection with the fish-borne liver fluke, Opisthorchis felineus on the biliary microbiome of residents of the Tomsk region of western Siberia. Methodology/Principal Findings Samples of bile were provided by 56 study participants, half of who were infected with O. felineus, and all of who were diagnosed with gallstone disease. The microbiota of the bile was investigated using high throughput, Illumina-based sequencing targeting the prokaryotic 16S rRNA gene. About 2,797, discrete phylotypes of prokaryotes were detected. At the level of phylum, bile from participants with opisthorchiasis showed greater numbers of Synergistetes, Spirochaetes, Planctomycetes, TM7 and Verrucomicrobia. Numbers of > 20 phylotypes differed in bile of the O. felineus-infected compared to non-infected participants, including presence of species of the genera Mycoplana, Cellulosimicrobium, Microlunatus and Phycicoccus, and the Archaeans genus, Halogeometricum, and increased numbers of Selenomonas, Bacteroides, Rothia, Leptotrichia, Lactobacillus, Treponema and Klebsiella. Conclusions/Significance Overall, infection with the liver fluke O. felineus modified the biliary microbiome, increasing abundance of bacterial and archaeal phylotypes. PMID:27447938

    High-risk primary biliary cholangitis (PBC), defined by inadequate response at one year to Ursodeoxycholic acid (UDCA), is associated with disease progression and liver transplantation. Stratifying high-risk patients early would facilitate improved approaches to care. Using long-term follow-up data to define risk at presentation, 6 high-risk PBC patients and 8 low-risk patients were identified from biopsy, transplant and biochemical archival records. Formalin-fixed paraffin-embedded (FFPE) liver biopsies taken at presentation were graded (Scheuer and Nakanuma scoring) and gene expression analysed using the NanoString® nCounter PanCancer Immunity 770-gene panel. Principle component analysis (PCA) demonstrated discrete gene expression clustering between controls and high- and low-risk PBC. High-risk PBC was characterised by up-regulation of genes linked to T-cell activation and apoptosis, INF-γ signalling and leukocyte migration and down-regulation of those linked to the complement pathway. CDKN1a, up-regulated in high-risk PBC, correlated with significantly increased expression of its gene product, the senescence marker p21(WAF1/Cip), by biliary epithelial cells. Our findings suggest high- and low-risk PBC are biologically different from disease outset and senescence an early feature in high-risk disease. Identification of a high-risk 'signal' early from standard FFPE tissue sections has clear clinical utility allowing for patient stratification and second-line therapeutic intervention.

    Biliary atresia is a rare disease of infancy, with an estimated 1 in 15,000 frequency in the southeast United States, but more common in East Asian countries, with a reported frequency of 1 in 5,000 in Taiwan. Although much is known about the management of biliary atresia, its pathogenesis is still elusive. The sea lamprey (Petromyzon marinus) provides a unique opportunity to examine the mechanism and progression of biliary degeneration. Sea lamprey develop through three distinct life stages: larval, parasitic, and adult. During the transition from larvae to parasitic juvenile, sea lamprey undergo metamorphosis with dramatic reorganization and remodeling in external morphology and internal organs. In the liver, the entire biliary system is lost, including the gall bladder and the biliary tree. A newly-developed method called “CLARITY” was modified to clarify the entire liver and the junction with the intestine in metamorphic sea lamprey. The process of biliary degeneration was visualized and discerned during sea lamprey metamorphosis by using laser scanning confocal microscopy. This method provides a powerful tool to study biliary atresia in a unique animal model.

  19. Biliary obstruction dissipates bioelectric sinusoidal-canalicular barrier without altering taurocholate uptake

    To study immediate events during extrahepatic cholestasis, we investigated the effect of short-term biliary obstruction on the bioelectrical sinusoidal-canalicular barrier in the rat using molecular weight-matched uncharged and negatively charged inert solute pairs. The bioelectrical barrier averaged -22 +/- 5 and -18 +/- 4 mV (NS) using the pair carboxy-/methoxyinulin and ferrocyanide/sucrose, respectively. After a 20-min biliary obstruction both decreased by 61 and 11%, respectively, but only the large molecular weight pair (the inulins) returned to base line after release of the obstruction. Inert solute clearances were increased after short biliary obstruction depending on molecular size and negative charge (ferrocyanide greater than sucrose greater than carboxyinulin greater than inulin), suggesting that both permeability and bioelectrical barriers were affected by obstruction. The hepatic extraction in vivo of a passively transported drug not excreted into bile (D-propranolol) was not affected by obstruction, whereas that of an actively transported drug (glycocholate) decreased from 66 +/- 8 to 41 +/- 20% during biliary obstruction (P less than 0.01). Unidirectional transfer of glycocholate was not affected by short-term biliary obstruction in the situ perfused rat liver; however, 2 min after (14C)glycocholate administration, increased return was observed in hepatic venous effluent in obstructed animals. Our findings demonstrate a loss of the bioelectrical barrier immediately after short-term biliary obstruction. Decreased hepatic extraction in the view of unaltered sinusoidal uptake demonstrates regurgitation of bile into blood during short-term biliary obstruction.

    Background. Iatrogenic biliary injuries are considered as the most serious complications during cholecystectomy. Better outcomes of such injuries have been shown in cases managed in a specialized center. Objective. To evaluate biliary injuries management in major referral hepatobiliary center. Patients & Methods. Four hundred seventy-two consecutive patients with postcholecystectomy biliary injuries were managed with multidisciplinary team (hepatobiliary surgeon, gastroenterologist, and radiologist) at major Hepatobiliary Center in Egypt over 10-year period using endoscopy in 232 patients, percutaneous techniques in 42 patients, and surgery in 198 patients. Results. Endoscopy was very successful initial treatment of 232 patients (49%) with mild/moderate biliary leakage (68%) and biliary stricture (47%) with increased success by addition of percutaneous (Rendezvous technique) in 18 patients (3.8%). However, surgery was needed in 198 patients (42%) for major duct transection, ligation, major leakage, and massive stricture. Surgery was urgent in 62 patients and elective in 136 patients. Hepaticojejunostomy was done in most of cases with transanastomotic stents. There was one mortality after surgery due to biliary sepsis and postoperative stricture in 3 cases (1.5%) treated with percutaneous dilation and stenting. Conclusion. Management of biliary injuries was much better with multidisciplinary care team with initial minimal invasive technique to major surgery in major complex injury encouraging early referral to highly specialized hepatobiliary center.

    A 56-year-old woman visited our hospital because of high fever and right hypochondralgia. Abdominal computed tomography showed a liver cyst 10 cm in diameter and dilatation of the intrahepatic bile duct. Percutaneous transhepatic drainage of the cyst guided by ultrasonography disclosed that the cyst contained a brown milky fluid, and cystography showed biliary communication. Thus, the cyst was diagnosed as an infectious hepatic cyst with biliary communication. Treatments for liver cysts include aspiration therapy, alcoholic sclerotherapy, laparoscopic fenestration, fenestration by laparotomy, cystojejunostomy, cystectomy, and hepatectomy. Because a simple liver cyst is benign, treatments should be low-risk and minimally invasive; thus, we performed laparoscopic fenestration. Fenestration should not be performed if the case is complicated by infection or biliary communication. Although cystography showed biliary communication, the cyst was not visualized with endoscopic retrograde cholangiography, and we concluded that the biliary communication was small. Operation time was 95 minutes, and blood loss was 10 g. Pathological findings of the liver cyst were consistent with a simple cyst. The postoperative course was good, and the patient left the hospital 10 days after the operation. Eighteen months have passed since the operation, and no recurrent cysts have been detected with computed tomography. This is the second report of liver cyst with biliary communication successfully treated with laparoscopic deroofing. Laparoscopic fenestration is a useful method for treating simple benign liver cysts because of its minimal invasiveness and may be useful in cases with small biliary communication.

    Gallstone disease is very common and laparoscopic cholecystectomy is one of the most common surgical procedures all over the world. Parallel to the increase in the number of laparoscopic cholecystectomies, bile duct injuries also increased. The reported incidence of bile duct injuries ranges from 0.3% to 1.4%. Many of the bile duct injuries during laparoscopic cholecystectomy are not due to inexperience, but are the result of basic technical failures and misinterpretations. A working group of expert hepatopancreatobiliary surgeons, an endoscopist, and a specialist of forensic medicine study searched and analyzed the publications on safe cholecystectomy and biliary injuries complicating laparoscopic cholecystectomy under the organization of Turkish Hepatopancreatobiliary Surgery Association. After a series of e-mail communications and two conferences, the expert panel developed consensus statements for safe cholecystectomy, management of biliary injuries and medicolegal issues. The panel concluded that iatrogenic biliary injury is an overwhelming complication of laparoscopic cholecystectomy and an important issue in malpractice claims. Misidentification of the biliary system is the major cause of biliary injuries. To avoid this, the “critical view of safety” technique should be employed in all the cases. If biliary injury is identified intraoperatively, reconstruction should only be performed by experienced hepatobiliary surgeons. In the postoperative period, any deviation from the expected clinical course of recovery should alert the surgeon about the possibility of biliary injury. PMID:28149133

    Biliary atresia is a rare birth defect that affects 1 in 12,000 to 1 in 19,500 live births. We used data from the National Birth Defects Prevention Study, a multistate case-control study, to identify potential risk factors for isolated biliary atresia (no additional unrelated major birth defects diagnosed). Infants were identified from eight states from 1997 to 2002, with clinical information abstracted from medical records. Potential risk factors assessed include: demographic factors, seasonality, preterm birth, maternal smoking, maternal alcohol use, maternal illicit drug use, maternal health, maternal medication use, maternal vitamin use, and maternal nutrition. Infants of non-Hispanic black mothers were more likely to have biliary atresia than infants of non-Hispanic white mothers (adjusted odds ratio (aOR) = 2.29, 95% confidence interval (CI) 1.07-4.93) and infants conceived during the spring season were more likely to have biliary atresia than infants conceived in winter (aOR = 2.33, 95%CI 1.05-5.16). Low intakes of vitamin E, copper, phosphorus, and beta tocopherol were associated with the occurrence of isolated biliary atresia (borderline significance). Low iron intake had a borderline inverse association with biliary atresia. While this analysis provides support for previous reports of a possible association between seasonal variation and the occurrence of biliary atresia, more data are needed to evaluate whether the seasonal variation is related to infectious agents. The role of nutrients in the development of biliary atresia remains unclear. Further studies of genetic, infectious, and nutrient exposures and the association of biliary atresia are warranted.

    The biliary tract and pancreas are located closely anatomically, and both develop from the endoderm foregut almost at the same time. Interestingly, the lining epithelia of the bile duct and main pancreatic duct show similar morphologies and phenotypes, and both are accompanied by periductal glands. Furthermore, the exocrine pancreatic acini are remnantly found in the peribiliary glands. Based on these findings, it seems plausible that the biliary tract has features of pancreatic elements in addition to the duct system, which is specialized for the drainage of bile secreted by hepatic parenchyma, particularly, hepatocytes. Interestingly, some pancreatic and biliary diseases show similar pathological features and even biological behaviors. For example, extrahepatic cholangiocarcinoma and ductal adenocarcinoma of the pancreas share many clinicopathological features. Both of them are hypothesized to arise from similar preneoplastic and early neoplastic intraepithelial lesions. Intraductal papillary tumors, with frequent mucin hyperproduction, develop in the pancreas (intraductal papillary mucinous neoplasm) and also in the biliary tract (intraductal papillary neoplasm of the bile duct). IgG4-related disease affects the biliary tract (IgG4-related sclerosing cholangitis) and the pancreas (autoimmune pancreatitis) in the same patients, with both showing similar morphologies. Herein, we propose that these non-neoplastic and neoplastic biliary diseases showing similarities to corresponding pancreatic diseases could be included in a new disease concept "biliary diseases with pancreatic counterparts". Based on this new concept, information obtained in biliary tract diseases could be applied to the analysis of pancreatic disease and vice versa, and also novel therapeutical strategies and molecular and genetic studies on pancreatic and biliary diseases may be developed with a unified approach.

    We investigated the hypothesis that lysosomes are the main source of biliary copper in conditions of hepatic copper overload. We used a rat model of oral copper loading and studied the relationship between the biliary output of copper and lysosomal hydrolases. Male Sprague-Dawley rats were given tap water with or without 0.125% copper acetate for up to 36 wk. Copper loading produced a 23-fold increase in the hepatic copper concentration and a 30-65% increase in hepatic lysosomal enzyme activity. Acid phosphatase histochemistry showed that copper-loaded livers contained an increased number of hepatocyte lysosomes; increased copper concentration of these organelles was confirmed directly by both x ray microanalysis and tissue fractionation. The copper-loaded rats showed a 16-fold increase in biliary copper output and a 50-300% increase in biliary lysosomal enzyme output. In the basal state, excretory profiles over time were similar for biliary outputs of lysosomal enzymes and copper in the copper-loaded animals but not in controls. After pharmacologic stimulation of lysosomal exocytosis, biliary outputs of copper and lysosomal hydrolases in the copper-loaded animals remained coupled: injection of colchicine or vinblastine produced an acute rise in the biliary output of both lysosomal enzymes and copper to 150-250% of baseline rates. After these same drugs, control animals showed only the expected increase in lysosomal enzyme output without a corresponding increase in copper output. We conclude that the hepatocyte responds to an increased copper load by sequestering excess copper in an increased number of lysosomes that then empty their contents directly into bile. The results provide direct evidence that exocytosis of lysosomal contents into biliary canaliculi is the major mechanism for biliary copper excretion in hepatic copper overload.

    Purpose. The purpose of this study is to evaluate the efficacy of palliation of malignant biliary and duodenal obstruction with combined metallic stenting under fluoroscopy guidance. Materials and Methods. A retrospective analysis of 9 patients (6 men and 3 women) who underwent biliary and duodenal stenting was performed. The mean age of patients was 61 years (range: 42-80 years). The causes of obstruction were pancreatic carcinoma in 7 patients, cholangiocellular carcinoma in one, and duodenal carcinoma in the other. Biliary and duodenal stents were placed simultaneously in 4 patients. In other 5 patients dudodenal stents were placed after biliary stenting when the duodenal obstruction symptoms have developed. In two patients duodenal stents were advanced via transgastric approach. Results. Technical success rate was 100 %. After percutaneous biliary drainage and stenting bilirubin levels decreased to normal levels in 6 patients and in remaining 3 patients mean reduction of 71% in bilirubin levels was achieved. Tumoral ingrowth occurred in one patient and percutaneous biliary restenting was performed 90 days after the initial procedure. Of the 9 patients, 6 patients were able to tolerate solid diet, whereas 2 patients could tolerate liquid diet and one patient did not show any improvement. Mean survival periods were 111 and 73 days after biliary and duodenal stenting, respectively. Conclusion. Combined biliary and duodenal stent placement which can be performed under fluoroscopic guidance without assistance of endoscopy is feasible and an effective method of palliation of malignant biliary and duodenal obstructions. If transoral and endoscopic approaches fail, percutaneous gastrostomy route allows duodenal stenting.

    Choledochoscopy it's a common method of intraoperative exploring of the extrahepatic biliary ducts and partially of the intrahepatic ones. He is used both in the open and laparoscopic surgery. We consider the operative cholangiogram, preferably transcystic, as a first step who precedes the endoscopic exploration. The transcystic choledochoscopy has specific and relatively narrow indications: undulated biliary ducts, 1-3 gallstones. The transcholedocian choledochoscopy permit a direct and complete exploration of the biliary ducts. The important diagnostic help that fibrocholedochoscopy gives in, it's accomplished by the possibility of therapeutic maneuvers (especially the gallstones extraction), which offers the quality of a miniinvasive, elegant and harmless treatment technique.

    Biliary stenting is clinically effective in relieving both malignant and non-malignant obstructions. However, there are high failure rates associated with tumor ingrowth and epithelial overgrowth as well as internally from biofilm development and subsequent clogging. Within the last decade, the use of prophylactic drug eluting stents as a means to reduce stent failure has been investigated. In this review we provide an overview of the current research on drug eluting biliary stents. While there is limited human trial data regarding the clinical benefit of drug eluting biliary stents in preventing stent obstruction, recent research suggests promise regarding their safety and potential efficacy.

    The immunosuppressant tacrolimus has a narrow therapeutic window, necessitating therapeutic drug monitoring to maintain efficacy and minimise toxicity. There are very few reports examining the impact of impaired biliary excretion on tacrolimus blood levels or toxicity. We report the case of a 26-year-old combined liver and kidney transplant recipient, who developed acute biliary obstruction leading to tacrolimus toxicity with very high blood tacrolimus levels. Despite a careful evaluation, no alternative cause was found for her acute kidney injury, and her kidney function returned to previous baseline within several days following treatment of the biliary obstruction and temporary withdrawal of tacrolimus.

    Advanced biliary tract carcinomas (BTCs) are often diagnosed at an advanced/metastatic stage and have a poor prognosis. The combination of gemcitabine and oxaliplatin (GEMOX) has shown promising activity in this setting. This international phase II study evaluated the efficacy and safety of GEMOX as first-line therapy in patients with advanced BTCs. Eligible patients with previously untreated locally advanced or metastatic BTC received gemcitabine 1000 mg m−2 (day 1) and oxaliplatin 100 mg m−2 (day 2), every 2 weeks. Seventy patients were enroled; 72.9% had metastatic disease. Sixty-seven patients were treated. There were 10 confirmed partial responses (14.9%; 95% confidence interval (CI), 7.4–25.7%) in the treated population (RECIST). Twenty-four patients (35.8 %) had stable disease. The objective response rate was 20.5% in patients with non-gallbladder cancers (9/44 patients) and 4.3% in patients with gallbladder cancers (1/23). Median overall survival for the intent-to-treat population was 8.8 months (95% CI, 6.9–11.1%) and progression-free survival was 3.4 months (95% CI, 2.5–4.6%). Grade 3/4 toxicities included thrombocytopenia (14.9% of patients), alanine aminotransferase elevation (13.4%), anaemia (10.4%), neutropenia (11.9%) and pain (11.9%). In this study, GEMOX demonstrated activity in non-gallbladder carcinoma, but poor activity in gallbladder carcinoma. GEMOX is well tolerated in advanced BTCs. PMID:19238628

    We report a patient with chronic inflammatory demyelinating polyneuropathy associated with primary biliary cirrhosis (PBC). Except for minimal biochemical abnormalities, clinical symptoms of PBC were not observed, and we diagnosed our patient with asymptomatic PBC from the results of a liver biopsy. Although the patient noticed little muscle weakness, an electrophysiological study demonstrated slow conduction velocities and prolonged distal latencies, with definite conduction blocks in the median, ulnar, and tibial nerves. The disturbed sensory pattern was asymmetrical, and sensory nerve action potentials were not evoked. From these observations, we diagnosed this patient with chronic inflammatory demyelinating polyneuropathy. Neuropathy associated with PBC is very rare. We must differentiate demyelinating neuropathy with PBC in patients with asymmetrical sensory dominant neuropathy with high immunoglobulin M titers, and investigate for the presence of anti-mitochondrial antibodies to rule out a complication of asymptomatic PBC.

    Summary Hepatocytes and cholangiocytes self renew following liver injury. Following severe injury hepatocytes are increasingly senescent, whether Hepatic Progenitor Cells (HPCs) then contribute to liver regeneration is unclear. Here, we describe a mouse model where Mdm2 is inducibly deleted in over 98% of hepatocytes, causing apoptosis, necrosis and senescence with nearly all hepatocytes expressing p21. This results in florid HPC activation, which is necessary for survival, followed by complete, functional liver reconstitution. HPCs isolated from genetically normal mice, using cell surface markers, were highly expandable and phenotypically stable in vitro. These HPCs were transplanted into adult mouse livers where hepatocyte Mdm2 was repeatedly deleted, creating a non-competitive repopulation assay. Transplanted HPCs contributed significantly to restoration of liver parenchyma, regenerating hepatocytes and biliary epithelia, highlighting their in vivo lineage potency. HPCs are therefore a potential future alternative to hepatocyte or liver transplantation for liver disease. PMID:26192438

    2016-01-01

    Primary biliary cirrhosis (PBC) is characterized by progressive nonsuppurative destruction of small bile ducts, resulting in intrahepatic cholestasis, fibrosis and ultimately end-stage liver disease. Timely intervention with ursodeoxycholic acid is associated with excellent survival, although approximately one-third of all patients fail to achieve biochemical response, signifying a critical need for additional therapeutic strategies. Obeticholic acid (OCA) is a potent ligand of the nuclear hormone receptor farnesoid X receptor (FXR). Activation of FXR inhibits bile acid synthesis and protects against toxic accumulation in models of cholestasis and facilitates hepatic regeneration in preclinical studies. Data from recent Phase II and III controlled trials suggest a therapeutic impact of OCA in PBC biochemical nonresponders, as evidenced by change in proven laboratory surrogates of long-term outcome. Dose-dependent pruritus is a common adverse effect, but may be overcome through dose-titration. Longer term studies are needed with focus on safety and long-term clinical efficacy.

    Uridine, a pyrimidine nucleoside present at high levels in the plasma of rodents and humans, is critical for RNA synthesis, glycogen deposition, and many other essential cellular processes. It also contributes to systemic metabolism, but the underlying mechanisms remain unclear. We found that plasma uridine levels are regulated by fasting and refeeding in mice, rats, and humans. Fasting increases plasma uridine levels, and this increase relies largely on adipocytes. In contrast, refeeding reduces plasma uridine levels through biliary clearance. Elevation of plasma uridine is required for the drop in body temperature that occurs during fasting. Further, feeding-induced clearance of plasma uridine improves glucose metabolism. We also present findings that implicate leptin signaling in uridine homeostasis and consequent metabolic control and thermoregulation. Our results indicate that plasma uridine governs energy homeostasis and thermoregulation in a mechanism involving adipocyte-dependent uridine biosynthesis and leptin signaling.

    Biliary tract cancers (BTCs) include cholangiocarcinoma (intrahepatic, perihilar and extrahepatic), carcinoma of the gall bladder and ampullary carcinoma. In patients with advanced disease the prognosis is poor. There is not a consensus regarding treatment strategy. Chemotherapy has only limited efficacy. This review summarizes the new approaches for BTC patients and the rationale for targeted therapies. The prognostic factors and the molecular features of BTC are analyzed. The clinical trials evaluating the targeted agents are accurately described, especially those assessing the role of anti-EGFR and antiangiogenic drugs. The ongoing trials are also analyzed. In fact, only the results of these trials will establish which is the most effective agent or combination for this setting.

  7. Biliary Secretion of Quasi-Enveloped Human Hepatitis A Virus

    PubMed Central

    2016-01-01

    ABSTRACT Hepatitis A virus (HAV) is an unusual picornavirus that is released from cells cloaked in host-derived membranes. These quasi-enveloped virions (eHAV) are the only particle type circulating in blood during infection, whereas only nonenveloped virions are shed in feces. The reason for this is uncertain. Hepatocytes, the only cell type known to support HAV replication in vivo, are highly polarized epithelial cells with basolateral membranes facing onto hepatic (blood) sinusoids and apical membranes abutting biliary canaliculi from which bile is secreted to the gut. To assess whether eHAV and nonenveloped virus egress from cells via vectorially distinct pathways, we studied infected polarized cultures of Caco-2 and HepG2-N6 cells. Most (>99%) progeny virions were released apically from Caco-2 cells, whereas basolateral (64%) versus apical (36%) release was more balanced with HepG2-N6 cells. Both apically and basolaterally released virions were predominantly enveloped, with no suggestion of differential vectorial release of eHAV versus naked virions. Basolateral to apical transcytosis of either particle type was minimal (<0.02%/h) in HepG2-N6 cells, arguing against this as a mechanism for differences in membrane envelopment of serum versus fecal virus. High concentrations of human bile acids converted eHAV to nonenveloped virions, whereas virus present in bile from HAV-infected Ifnar1−/− Ifngr1−/− and Mavs−/− mice banded over a range of densities extending from that of eHAV to that of nonenveloped virions. We conclude that nonenveloped virions shed in feces are derived from eHAV released across the canalicular membrane and stripped of membranes by the detergent action of bile acids within the proximal biliary canaliculus.

    Primary biliary cirrhosis (PBC), a classic autoimmune liver disease, is characterised by a progressive T cell predominant lymphocytic cholangitis, and a serologic pattern of reactivity in the form of specific anti-mitochondrial antibodies (AMA). CD4+ T cells are particularly implicated by PBC's cytokine signature, the presence of CD4+ T cells specific to mitochondrial auto-antigens, the expression of MHC II on injured biliary epithelial cells, and PBC's coincidence with other similar T cell mediated autoimmune conditions. CD4+ T cells are also central to current animal models of PBC, and their transfer typically also transfers disease. The importance of genetic risk to developing PBC is evidenced by a much higher concordance rate in monozygotic than dizygotic twins, increased AMA rates in asymptomatic relatives, and disproportionate rates of disease in siblings of PBC patients, PBC family members and certain genetically defined populations. Recently, high-throughput genetic studies have greatly expanded our understanding of the gene variants underpinning risk for PBC development, so linking genetics and immunology. Here we summarize genetic association data that has emerged from large scale genome-wide association studies and discuss the evidence for the potential functional significance of the individual genes and pathways identified; we particularly highlight associations in the IL-12-STAT4-Th1 pathway. HLA associations and epigenetic effects are specifically considered and individual variants are linked to clinical phenotypes where data exist. We also consider why there is a gap between calculated genetic risk and clinical data: so-called missing heritability, and how immunogenetic observations are being translated to novel therapies. Ultimately whilst genetic risk factors will only account for a proportion of disease risk, ongoing efforts to refine associations and understand biologic links to disease pathways are hoped to drive more rational therapy for

    The effects of early postoperative nasoduodenal feeding on nutrition and metabolic response were studied using 24 patients after biliary surgery. The patients were randomly divided into two groups with 12 in each group. Group I was fed via a nasoduodenal tube from the first postoperative day but control group II was not fed until the fourth postoperative day. The hospital blenderized tube feeding diet provided the enteric nutrition (17% protein, 33% fat and 50% carbohydrate). The nutritional status of the 2 groups was compared over a one week period. The changes in nitrogen balance were measured daily for 8 days. The group fed early had a significantly reduced negative nitrogen balance when compared to the group whose feeding was started later. (-1.91 +/- 1.05 g/day vs -5.84 +/- 0.48 g/day). There was no difference in serum albumin and transferrin levels, but serum prealbumin levels in the group fed early were more desirable than those of the control group (from 15.8 +/- 2.5 mg/dl to 28.9 +/- 3.8 mg/dl vs from 18.0 +/- 2.0 mg/dl to 25.9 +/- 3.9 mg/dl). Total lymphocyte count was also better in the group fed early than in the controls (from 1,325 +/- 204 cells/mm3 to 2,655 +/- 584 cells/mm3 vs from 1,277 +/- 188 cells/mm3 to 1,877 +/- 440 cells/mm3). All the patients in group I felt better than those in group II during the study course. These results indicated that those patients provided with early nasoduodenal feeding after a biliary operation displayed a better nitrogen balance, and a faster increase in short half life visceral protein and total lymphocyte count.

    Aims: In 1955, Professor Morio Kasai first performed a hepatic portoenterostomy. Since then, the procedure has changed the lives of children with biliary atresia (BA). We report our initial experience in performing “extended” Kasai portoenterostomy (KPE), a modification of the original procedure. Materials and Methods: Since 2013, we have used the technique of “extended KPE” and prospectively recorded data on all children undergoing this operation. Data on demographics, clinical features, liver function tests, and perioperative cholangiogram findings were collected. Outcome of KPE was measured by Jaundice Disappearance Rate (JDR) and Native Liver Survival Rate (NLSR). We present our preliminary results from a 30-month period (February 2013 to May 2015). Results: Thirty-one children underwent KPE during this period (19 males) and only 1 child had biliary atresia splenic malformation (BASM). The mean age at KPE was 73 ± 24 days. Five (16.1%) children were more than 90 days old at the time of KPE. Fourteen children cleared jaundice (JDR 45.2%). Eleven (35.5%) children developed episodes of cholangitis, of whom 8 had early cholangitis (within 3 months of the operation). The proportion of children who survived with their own liver 6 months after KPE (NLSR) was 84.2%. Of those children older than 90 days, 2 cleared jaundice and have survived with their native livers for more than 16 months. Conclusion: In our preliminary report of 31 children, we conclude that the extended KPE leads to increased jaundice clearance and improved NLSR in children with BA. PMID:27046977

    Introduction Non-specific neck pain has a postural or mechanical basis and affects about two thirds of people at some stage, especially in middle age. Acute neck pain resolves within days or weeks, but may become chronic in about 10% of people. Whiplash injuries follow sudden acceleration–deceleration of the neck, such as in road traffic or sporting accidents. Up to 40% of people continue to report symptoms 15 years after the accident, although this varies between countries. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for people with non-specific neck pain without severe neurological deficit? What are the effects of treatments for acute whiplash injury? What are the effects of treatments for chronic whiplash injury? What are the effects of treatments for neck pain with radiculopathy? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2007 (BMJ Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 91 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of the evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, biofeedback, drug treatments (analgesics, antidepressants, epidural steroid injections, muscle relaxants, non-steroidal anti-inflammatory drugs [NSAIDs]), early mobilisation, early return to normal activity, exercise, heat or cold, manipulation (alone or plus exercise), mobilisation, multimodal treatment, patient education, percutaneous radiofrequency neurotomy

    Biliary tract cancers are aggressive malignancies that include gallbladder cancer and tumors of intra- and extrahepatic ducts and have a poor prognosis. Surgical resection remains the main curative therapy. Nevertheless, numerous patients experience recurrence even after radical surgery. This scenario drives the research to identify biliary tract cancer biomarkers despite the limited progress that has been made. Recently, a large number of studies have demonstrated that deregulated expression of microRNAs is closely associated with cancer development and progression. In this review, we highlight the role and importance of microRNAs in biliary tract cancers with an emphasis on utilizing circulating microRNAs as potential biomarkers. Additionally, we report several single-nucleotide polymorphisms in microRNA genes that are associated with the susceptibility of biliary tract tumors. PMID:28115929

    Biliary complication remains a significant source of morbidity and mortality in living donor liver transplantation. From October 1996 to December 1999, 34 patients underwent 35 living donor liver transplantations at Kyushu University Hospital. In the initial twenty cases, anastomotic internal stents were placed. In the most recent fifteen cases, no internal stent was inserted and routine postreconstruction dye injection leakage tests were administered. In recipient biliary reconstruction, hepaticojejunostomy was performed using interrupted sutures without an anastomotic stent. After an intestinal clamp was applied at the anal side of the hepaticojejunostomy, leakage test was done using diluted indigocarmine solution injected into the jejunal loop lumen. Two (13%) of the fifteen recent patients suffered from biliary complications, whereas eight patients (40%) from the former twenty patients suffered from biliary complications. We conclude that the use of the stent was not useful, but the application of the dye injection leakage test was useful.

    We describe a new method for relieving biliary obstruction due to malignant solid tumors. The method consists of placement of radium needles in a Ring biliary drainage catheter for three days. After removing the radium needles, the catheter is left in place to allow for repair of irradiated tissues, then it is removed. The object is to leave the patient with a patent biliary tree without a biliary drainage prosthesis. The clinical course of six patients treated by this method is described, and the autopsy findings in three cases are outlined. Three patients died with a serum total bilirubin ranging from 1--4.5 mg/100 ml, two to three months after removing the drainage catheter. Two patients died before the bile drainage catheter could be removed. One patient is alive with a bile drainage catheter in place. Possible modifications in technique and catheters are being considered.

A total of 63 patients were diagnosed with cholecystolithiasis and choledocholithiasis. The present study performed a retrospective analysis of clinical samples from 16 of these patients who had incarcerated calculi at the terminus of the common bile duct, and who had been treated with laparoscopic cholecystectomy and LCBDE. During the procedure, laparotomy biliary lithotomy forceps were used to gently remove the calculi from the common bile duct. Of the surgical procedures that used laparotomy biliary lithotomy forceps, one case was unsuccessful and 15 cases were successful. The results of the present study suggested that it may be clinically advisable to use laparotomy biliary lithotomy forceps to remove incarcerated calculi from the common bile duct during a laparoscopy, since it is easy, economical and effective.

    In experiment on rabbits a comparative analysis of various methods of a biliary peritonitis simulation was conducted. In 6 animals a biliary peritonitis was simulated, using perforation of a gallbladder, local serous-fibrinous peritonitis have occurred in 50% of them. In 7 animals biliary peritonitis was simulated, applying intraabdominal injection of medical sterile bile in a 5-40 ml volume. Diffuse peritonitis with exudates and stratification of fibrin was absent. Most effective method have appeared that, when intraabdominal injection of bile was done together with E. coli culture in the rate of 0.33 microbal bodies McF (1.0 x 10(8) CFU/ml) on 1 kg of the animal body mass. Diffuse biliary peritonitis have occurred in all 23 animals, including serous-fibrinous one--in 17 (76%), and purulent-fibrinous--in 6 (24%).

    Cells with slow proliferation kinetics that retain the nuclear label over long time periods–the label-retaining cells (LRCs)–represent multipotent stem cells in a number of adult tissues. Since the identity of liver LRCs (LLRCs) had remained elusive we utilized a genetic approach to reveal LLRCs in normal non-injured livers and characterized their regenerative properties in vivo and in culture. We found that LLRCs were located in biliary vessels and participated in the regeneration of biliary but not hepatocyte injury. In culture experiments the sorted LLRCs displayed an enhanced self-renewal capacity but a unipotent biliary differentiation potential. Transcriptome analysis revealed a unique set of tumorigenesis- and nervous system-related genes upregulated in LLRCs when compared to non-LRC cholangiocytes. We conclude that the LLRCs established during the normal morphogenesis of the liver do not represent a multipotent primitive somatic stem cell population but act as unipotent biliary progenitor cells.

    Biliary obstruction caused by small simple cysts is very rare. We present a case of biliary dilatation caused by a simple cyst with a 4-cm diameter. The patient was a 75-year-old woman referred to our hospital for evaluation of a cystic tumor associated with peripheral biliary duct dilatation in the left segment of the liver. Computed tomography and magnetic resonance imaging showed that the cyst probably communicated with the intrahepatic bile duct. Malignant tumors, including intrahepatic papillary neoplasms of the bile duct, could not be ruled out; therefore, we performed surgery with the patient's consent. Histopathologic examination of the resected liver showed that the cystic lesion was a simple cyst. The finding that even small simple cysts can obstruct the biliary tract is important for the management of cystic lesions of the liver.

    The development of total biliary casts is very unusual, especially in patients who have not undergone liver transplantation. The aetiology of these casts is uncertain but several factors are believed to play a role, including periods of fasting, haemolysis, cholangitis and recent surgery. Resultant bile stasis and/or gallbladder hypocontractility promote sludge and subsequent stone formation. Here we present the case of a previously well 66-year-old woman who developed a total biliary cast several weeks after being involved in a road traffic accident during which she sustained head injuries but no obvious liver insult. This cast was removed at laparotomy but the patient had resultant diffuse biliary tree abnormalities and persistent cholestasis and subsequently required a liver transplant. The possible aetiologies of biliary cast formation and subsequently cholangiopathy necessitating transplantation in this patient are described.

    Biliary diversion offers a potential option for intractable pruritus in children with chronic cholestatic disorders. Progressive familial intrahepatic cholestasis (PFIC) is an inherited disorder of impaired bile acid transport and excretion, which presents with jaundice and pruritus in the first few months of life and progresses to cirrhosis by infancy or adolescence. We report a child with PFIC type 1 who underwent internal biliary diversion for intractable pruritus and was relieved of his symptoms.

    The multidrug resistance proteins P-glycoprotein (P-gp), breast cancer resistance protein (Bcrp), and multidrug resistance-associated protein 2 (Mrp2) are the three major canalicular transport proteins responsible for the biliary excretion of most drugs and metabolites. Previous in vitro studies demonstrated that P-gp transported macrolide antibiotics, including spiramycin, which is eliminated primarily by biliary excretion. Bcrp was proposed to be the primary pathway for spiramycin secretion into breast milk. In the present study, the contributions of P-gp, Bcrp, and Mrp2 to the biliary excretion of spiramycin were examined in single-pass perfused livers of male C57BL/6 wild-type, Bcrp-knockout, and Mrp2-knockout mice in the presence or absence of GF120918 (GW918), a P-gp and Bcrp inhibitor. Spiramycin was infused to achieve steady-state conditions, followed by a washout period, and parameters governing spiramycin hepatobiliary disposition were recovered by using pharmacokinetic modeling. In the absence of GW918, the rate constant governing spiramycin biliary excretion was decreased in Mrp2(-) knockout mice (0.0013 +/- 0.0009 min(-1)) relative to wild-type mice (0.0124 +/- 0.0096 min(-1)). These data are consistent with the approximately 8-fold decrease in the recovery of spiramycin in the bile of Mrp2-knockout mice and suggest that Mrp2 is the major canalicular transport protein responsible for spiramycin biliary excretion. Interestingly, biliary recovery of spiramycin in Bcrp-knockout mice was increased in both the absence and presence of GW918 compared to wild-type mice. GW918 significantly decreased the rate constant for spiramycin biliary excretion and the rate constant for basolateral efflux of spiramycin. In conclusion, the biliary excretion of spiramycin in mice is mediated primarily by Mrp2 with a modest P-gp component.

    The purpose of the present work was to study the level of microelements and vitamins in adolescents with diffuse nontoxic goiter. It has been shown that comorbid biliary dyskinesia leads to significant dysregulation of vitamin and mineral metabolism: the level of essential elements was decreased and the level of toxic elements was increased. Comorbid biliary dyskinesia in adolescents with diffuse nontoxic goiter was accompanied by a disbalance of vitamins. The changes found in micronutrients have sex differences.

    The biliary excretion of diazepam metabolites was found in rats. Equivalent dosages of diazepam were administered orally and intraperitoneally. The biliary excretion was dose-dependent and was greater following intraperitoneal administration. After intravenous administration, a greater percentage of the diazepam dosage administered was excreted into the bile. Repetitive intravenous administrations yielded results which approached those observed after intraperitoneally administered dosages given as a bolus.

    In biliary epithelial lesions in primary biliary cirrhosis (PBC), mitochondrial proteins associated with deregulated autophagy are abnormally expressed. We examined whether this could be used as a diagnostic marker for end-stage PBC and recurrent PBC after liver transplantation. We examined the expression of the mitochondrial protein pyruvate dehydrogenase complex-E2 component and cytochrome c oxidase, subunit I (CCO), the autophagy-related marker microtubule-associated protein-light chain 3 (LC3), and p62/sequestosome-1 and the senescence markers p16(Ink4a) and p21(WAF1/Cip1) in small bile ducts and bile ductules in explanted livers from patients with PBC (n = 20) in comparison with liver tissue from control patients (n = 21) and post-transplant samples including recurrent PBC and cellular rejection (n = 28). Intense granular expression of mitochondrial proteins was significantly more frequent in small bile ducts in explanted livers with PBC than in control livers (p < 0.05). Post-transplant samples comprised of three groups: group A (positive for mitochondrial proteins, n = 7), group B (positive for either autophagy-related or senescence markers but negative for mitochondrial proteins, n = 7), and group C (all negative, n = 14). All but one case of group A were clinically and histologically diagnosed as recurrent PBC. In contrast, all cases of group B were diagnosed as cellular rejection. This study suggests that the expression of mitochondrial proteins in small bile ducts may be a useful diagnostic marker for end-stage PBC and recurrent PBC after liver transplantation.

    Background Biliary complications are significant source of morbidity after liver transplantation (LT). Cholangiography is the gold standard for diagnosis and specification of biliary complications. Objectives Detailed analyses of ultrasound (US) as a safe imaging method in this regard are still lacking. Therefore we analyzed systematically the diagnostic value of US in these patients. Patients and Methods Retrospectively, 128 liver graft recipients and their clinical data were analyzed. All patients had a standardized US examination. The findings of US were compared to cholangiographic results in 42 patients. Following statistical analyses were performed: descriptive statistics, sensitivity, specificity, positive and negative predictive values (PPV, NPV). Results 42 patients had 54 different biliary complications (Anastomotic stenosis (AS) n = 33, ischemic type biliary lesions (ITBL) n = 18 and leakage n = 3). US detected n = 22/42 (52%) patients with biliary complications. The sensitivity, specificity, PPV and NPV of US were: 61%, 100%, 100%, 79% (95CI, 36-86%) for ITBL and 24%, 100, 100%, 31% (95CI, 9-46 %) for AS, respectively. Conclusions US examination had no false positive rate. Therefore, it may be helpful as a first screening modality. But for the direct diagnosis of the biliary complication US is not sensitive enough.

    The effects of a high cholesterol/cholate diet on the biliary secretion of bile acids, cholesterol, phospholipid and inorganic electrolytes in the rat were examined. Wistar rats were fed a hypercholesterolaemia-inducing diet (HID) for 20 days prior to the biliary experiments. Rats fed a standard laboratory diet were used as controls. The HID diet increased plasma cholesterol concentrations and the hepatic content of total, free and esterified cholesterol, without changes in ALP*, ALT and AST plasma activities. Bile flow and biliary secretion of bile acids and inorganic electrolytes were markedly increased in the hypercholesterolaemic animals. The stimulated biliary secretion was due to an increase in both the bile acid-dependent and bile acid-independent fractions of bile flow. An increase in the bile acid pool induced by the administration of exogenous cholic acid/cholesterol would account for these changes in bile flow and inorganic electrolyte secretion. Nevertheless, the increase in the bile acid-independent bile flow could be also related, at least to some extent, to a higher efficiency of bicarbonate transport into bile. The HID diet also increased both cholesterol and phospholipid biliary outputs, whereas it did not modify the relationship between lipid and bile acid secretion. The lithogenic index of bile was reduced in the rats after the HID regimen due to a relatively higher increase in the biliary outputs of phospholipids and bile acids than of cholesterol.

    Biliary excretion is an important route of elimination for many drugs, yet measuring the extent of biliary elimination is difficult, invasive, and variable. Biliary elimination has been quantified for few drugs with a limited number of subjects, who are often diseased patients. An accurate prediction of which drugs or new molecular entities are significantly eliminated in the bile may predict potential drug-drug interactions, pharmacokinetics, and toxicities. The Biopharmaceutics Drug Disposition Classification System (BDDCS) characterizes significant routes of drug elimination, identifies potential transporter effects, and is useful in understanding drug-drug interactions. Class 1 and 2 drugs are primarily eliminated in humans via metabolism and will not exhibit significant biliary excretion of parent compound. In contrast, class 3 and 4 drugs are primarily excreted unchanged in the urine or bile. Here, we characterize the significant elimination route of 105 orally administered class 3 and 4 drugs. We introduce and validate a novel model, predicting significant biliary elimination using a simple classification scheme. The model is accurate for 83% of 30 drugs collected after model development. The model corroborates the observation that biliarily eliminated drugs have high molecular weights, while demonstrating the necessity of considering route of administration and extent of metabolism when predicting biliary excretion. Interestingly, a predictor of potential metabolism significantly improves predictions of major elimination routes of poorly metabolized drugs. This model successfully predicts the major elimination route for poorly permeable/poorly metabolized drugs and may be applied prior to human dosing.

    Purpose. Previous clinical studies have shown the safety and efficacy of this novel radiofrequency ablation catheter when used for endoscopic palliative procedures. We report a retrospective study with the results of first in man percutaneous intraductal radiofrequency ablation in patients with malignant biliary obstruction. Methods. Thirty-nine patients with inoperable malignant biliary obstruction were included. These patients underwent intraductal biliary radiofrequency ablation of their malignant biliary strictures following external biliary decompression with an internal-external biliary drainage. Following ablation, they had a metal stent inserted. Results. Following this intervention, there were no 30-day mortality, hemorrhage, bile duct perforation, bile leak, or pancreatitis. Of the 39 patients, 28 are alive and 10 patients are dead with a median survival of 89.5 (range 14-260) days and median stent patency of 84.5 (range 14-260) days. One patient was lost to follow-up. All but one patient had their stent patent at the time of last follow-up or death. One patient with stent blockage at 42 days postprocedure underwent percutaneous transhepatic drain insertion and restenting. Among the patients who are alive (n = 28) the median stent patency was 92 (range 14-260) days, whereas the patients who died (n = 10) had a median stent patency of 62.5 (range 38-210) days. Conclusions. In this group of patients, it appears that this new approach is feasible and safe. Efficacy remains to be proven in future, randomized, prospective studies.

    Pain is a burdensome symptom that can commonly exist chronically along the cancer trajectory. Uncontrolled pain will impact on cancer patients' quality of life, even further negatively affect cancer survivors' employment. Based on systemic reviews of studies for past 10 years, the paper reported that although there is enormous advancement on the knowledge of cancer pain and pain management, studies still documented undertreatment of cancer pain globally. Additionally, pain distress a significant portion of cancer survivors. The pain in cancer survivors distinct from the pain related with cancer, instead emphasize on pain related with cancer treatment, such as neuropathic pain, muscular syndrome. Evidence-based pain management with common pain problems in cancer survivors is lacking. Further studies are needed to understand the pain in cancer survivors and to develop effective strategies in helping cancer survivors to manage their pain.

    Abstract Patient concerns: A 63-year-old man was hospitalized with history of abdominal pain since more than 1 year, and that of fever with chills since 2 weeks. Diagnoses: Based on the laboratory investigations and radiologic findings, a preliminary diagnosis of pancreatic intraductal papillary mucinous neoplasm (IPMN) with recurrent cholangitis and severe jaundice was made. Interventions: An initial attempt at endoscopic and image-guided drainage proved unsuccessful. Due to cholangitis, liver dysfunction, and hypoalbuminemia, the patient was deemed to be medically unfit for radical surgery. Therefore we considered a novel strategy of associating pancreaticostomy and biliary-irrigation for staged pancreaticoduodenectomy (APBSP). In the first stage, biliary tract double irrigation (endoscopic nasobiliary drainage and T-tube) in combination with pancreaticostomy was performed, which alleviated the symptoms and helped improve the general condition of the patient. In the second stage, radical pancreaticoduodenectomy was performed. Outcomes: Over a follow-up period of 23 months, no recurrence occurred. Lessons: In this report, we present a previously unreported treatment strategy for pancreatic IPMN with recurrent cholangitis and jaundice. The innovative treatment approach may help advance the understanding and management of this condition. PMID:27902614

    A 42 year-old African-American woman was admitted for severe acute right upper quadrant pain. Her liver function tests showed a cholestatic pattern of hepatitis. She had no known history of liver disease or sarcoidosis. Imaging of her liver and biliary tree did not reveal any apparent cause for her right upper quadrant pain. A liver biopsy was performed which showed granulomatous disease. This prompted a CT chest that showed mediastinal lymphadenopathy. Biopsy of the mediastinal lymphnode revealed non-caseating granulomas. Despite having no pulmonary symptoms or history of pulmonary sarcoidosis, she was diagnosed with systemic pulmonary sarcoidosis. She was treated with corticosteroids and had complete resolution of symptoms over the next several weeks.

    Chronic pain is common in patients with neurologic complications of a central nervous system insult such as stroke. The pain is most commonly musculoskeletal or related to obligatory overuse of neurologically unaffected limbs. However, neuropathic pain can result directly from the central nervous system injury. Impaired sensory discrimination can make it challenging to differentiate central neuropathic pain from other pain types or spasticity. Central neuropathic pain may also begin months to years after the injury, further obscuring recognition of its association with a past neurologic injury. This review focuses on unique clinical features that help distinguish central neuropathic pain. The most common clinical central pain syndromes-central poststroke pain, multiple sclerosis-related pain, and spinal cord injury-related pain-are reviewed in detail. Recent progress in understanding of the pathogenesis of central neuropathic pain is reviewed, and pharmacological, surgical, and neuromodulatory treatments of this notoriously difficult to treat pain syndrome are discussed.

    Background and Aim. A successful endoscopic ultrasound guided rendezvous (EUS-RV) biliary drainage is dependent on accurate puncture of the bile duct and precise guide wire manipulation across the ampulla of Vater. We aim to study the feasibility of using a flexible 19-gauge fine aspiration needle in the performance of EUS-RV biliary drainage. Method. This is a retrospective case series of EUS-RV biliary drainage procedures at a single center. Patients who failed ERCP during the same session for benign or malignant biliary obstruction underwent EUS-RV using a flexible, nitinol covered, 19-gauge needle for biliary access and guide wire manipulation. Result. 24 patients underwent EUS-RV biliary drainage via extrahepatic access while 1 attempt was via intrahepatic access. The technical success rate was 80%, including 83.3% of cases via extrahepatic access. There was no significant difference in success rate of inpatient and outpatient procedures, benign or malignant indications, or type of guide wire used. Adverse events included mild pancreatitis (3 patients) and cholangitis (1 patient). Conclusion. A flexible 19-gauge needle for biliary access can be safe and effective when used to perform EUS-RV biliary drainage. Direct comparison between the nitinol needle and conventional metal needles in the performance of EUS guided biliary drainage is needed. PMID:27822005

    Joint pain is common in haemophilia and may be acute or chronic. Effective pain management in haemophilia is essential to reduce the burden that pain imposes on patients. However, the choice of appropriate pain-relieving measures is challenging, as there is a complex interplay of factors affecting pain perception. This can manifest as differences in patients’ experiences and response to pain, which require an individualized approach to pain management. Prophylaxis with factor replacement reduces the likelihood of bleeds and bleed-related pain, whereas on-demand therapy ensures rapid bleed resolution and pain relief. Although use of replacement or bypassing therapy is often the first intervention for pain, additional pain relief strategies may be required. There is an array of analgesic options, but consideration should be paid to the adverse effects of each class. Nevertheless, a combination of medications that act at different points in the pain pathway may be beneficial. Nonpharmacological measures may also help patients and include active coping strategies; rest, ice, compression, and elevation; complementary therapies; and physiotherapy. Joint aspiration may also reduce acute joint pain, and joint steroid injections may alleviate chronic pain. In the longer term, increasing use of prophylaxis or performing surgery may be necessary to reduce the burden of pain caused by the degenerative effects of repeated bleeds. Whichever treatment option is chosen, it is important to monitor pain and adjust patient management accordingly. Beyond specific pain management approaches, ongoing collaboration between multidisciplinary teams, which should include physiotherapists and pain specialists, may improve outcomes for patients.

    Severe liver diseases are characterized by expansion of liver progenitor cells (LPC), which correlates with disease severity. However, the origin and role of LPC in liver physiology and in hepatic injury remains a contentious topic. We found that ductular reaction cells in human cirrhotic livers express hepatocyte nuclear factor 1 homeobox B (HNF1β). However, HNF1β expression was not present in newly generated epithelial cell adhesion molecule (EpCAM)-positive hepatocytes. In order to investigate the role of HNF1β- expressing cells we used a tamoxifen-inducible Hnf1βCreER/R26RYfp/LacZ mouse to lineage-trace Hnf1β+ biliary duct cells and to assess their contribution to LPC expansion and hepatocyte generation. Lineage tracing demonstrated no contribution of HNF1β+ cells to hepatocytes during liver homeostasis in healthy mice or after loss of liver mass. After acute acetaminophen or carbon tetrachloride injury no contribution of HNF1β+ cells to hepatocyte was detected. We next assessed the contribution of Hnf1β+ -derived cells following two liver injury models with LPC expansion, a diethoxycarbonyl-1,4-dihydrocollidin (DDC)-diet and a choline-deficient ethionine-supplemented (CDE)-diet. The contribution of Hnf1β+ cells to liver regeneration was dependent on the liver injury model. While no contribution was observed after DDC-diet treatment, mice fed with a CDE-diet showed a small population of hepatocytes derived from Hnf1β+ cells that were expanded to 1.86% of total hepatocytes after injury recovery. Genome-wide expression profile of Hnf1β+ -derived cells from the DDC and CDE models indicated that no contribution of LPC to hepatocytes was associated with LPC expression of genes related to telomere maintenance, inflammation, and chemokine signaling pathways. Conclusion HNF1β+ biliary duct cells are the origin of LPC. HNF1β+ cells do not contribute to hepatocyte turnover in the healthy liver, but after certain liver injury, they can differentiate to

    Purpose: To assess the information obtained by bile culture and susceptibility testing for malignant biliary obstruction by a retrospective one-center study. Methods: A total of 694 patients with malignant biliary obstruction received percutaneous transhepatic biliary drainage during the period July 2003 to September 2010, and subsequently, bile specimens were collected during the procedure. Among the 694 patients, 485 were men and 209 were women, ranging in age from 38 to 78 years (mean age 62 years). Results: A total of 42.9% patients had a positive bile culture (298 of 694). Further, 57 species of microorganisms and 342 strains were identified; gram-positive bacteria accounted for 50.9% (174 of 342) and gram-negative bacteria accounted for 41.5% (142 of 342) of these strains. No anaerobes were obtained by culture during this study. The most common microorganisms were Enterococcus faecalis (41 of 342, 11.9%), Escherichia coli (34 of 342, 9.9%), Klebsiella pneumoniae (28 of 342, 8.2%), Staphylococcus epidermidis (19 of 342, 5.5%), Enterococcus (18 of 342, 5.3%), and Enterobacter cloacae (16 of 342, 4.7%). The percentage of {beta}-lactamase-producing gram-positive bacteria was 27.6% (48 of 174), and the percentage of gram-negative bacteria was 19.7% (28 of 142). The percentage of enzyme-producing Escherichia coli was 61.7% (21 of 34). Conclusion: The bile cultures in malignant biliary obstruction are different from those in the Tokyo Guidelines and other benign biliary obstruction researches, which indicates that a different antibacterial therapy should be applied. Thus, knowledge of the antimicrobial susceptibility data could aid in the better use of antibiotics for the empirical therapy of biliary infection combined with malignant biliary obstruction.

    Purpose Biliary cancer is a highly malignant neoplasm with poor prognosis and most patients need to undergo palliative chemotherapy, however major clinical problem associated with the use of chemotherapy is chemoresistance. So far, we aimed at investigating clinical implications of apurinic/apyrimidinic endodeoxyribonuclease 1 (APEX1) and Jagged1 as chemoresistance factors in biliary tract cancer. Methods We used 5 human biliary tract cancer cell lines (SNU-245, SNU-308, SNU-478, SNU-1079, and SNU-1196), and investigated the chemosensitivity of APEX1 and Jagged1 through 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay and Western blot. Alternately, the 10 patients of advanced biliary cancer consist of 2 group according to the chemotherapy response examined by immunohistochemistry using APEX1 and Jagged1 antibody, and protein expression level was scored for staining intensity and percent positive cell. Results The result of MTT assay after APEX1 knockdown showed that strong coexpression of APEX1 and Jagged1 cell line (SNU-245, SNU-1079, and SNU-1196) showed a greater decrease in IC50 of chemotherapeutic agent (5-fluorouracil, gemcitabine and cisplatin). The Western blot analysis of APEX1 and Jagged1 expression in biliary cancer cell lines after APEX1 knockdown definitively demonstrated decreased Jagged1 expression. The APEX1 and Jagged1expression level of immunohistochemistry represented that chemorefractory patients had higher than chemoresponsive patients. Conclusion These results demonstrate that simultaneous high expression of APEX1 and Jagged1 is associated with chemoresistance in biliary cancer and suggest that is a potential therapeutic target for chemoresistance in advanced biliary cancer.

    We developed methods to isolate biliary epithelial cells (BECs) from the gallbladder (GB), common bile duct (CBD), intrahepatic large bile duct (ILBD) and small bile duct (ISBD) of a mouse, simultaneously. ILBD and ISBD were cut from the biliary tree after collagenase perfusion of the liver. BECs from all of these biliary segments were cultured as explants on collagen gel. BECs spread from the explants and formed cellular sheets. Areas of these sheets composed entirely of BECs were cut and placed on other gels as subculture, and this continued for 10 passages. Primary and passage cultured BECs on gel were composed of a monolayer of epithelial cells. Passaged cultured BECs in gel formed a spherical cyst lined by a single epithelial layer. Ultrastructurally, microvilli were dense on the luminal surface, and junctional complex and interdigitation was identifiable on the lateral surfaces. These features were similar in both primary and passaged cultured BECs, irrespective of their anatomical origin. Major histocompatibility complex antigens and intercellular adhesion molecule-1 were induced on the basolateral cell membranes of primary and passaged cultured BECs, by interferon-gamma. Although several phenotypic, structural and probable biological features of BECs inherent to each anatomical level may be lost after culture on gel, a combination of this method, several immunological modifications in experimental animals, and addition of immunologically active substances to the culture medium will make the immunopathologic analysis of biliary diseases possible.

    90 percent of symptomatic patients undergoing cholecystectomy have cholelithiasis with 10% categorized as asymptomatic cholecystitis. In both instances, the gallbladder is evident on ultrasonography. In children with symptomatic biliary dyspepsia, the decision to proceed to cholecystectomy is made difficult if choleliths are not seen on ultrasonography. This decision is made even more difficult if the gallbladder itself is not seen on repeated imaging. In a cohort of 54 cholecystectomies, 3 cases, with recurrent right upper quadrant pain and undetectable gallbladders on repeat ultrasonography, were identified. After prolonged observation all underwent successful cholecystectomy. Histology demonstrated a markedly fibrotic and thickened gallbladder in all. Given this experience, we suggest that nonvisibility of the gallbladder, in fact, maybe be a feature of a chronic acalculous cholecystitis. We advise consideration of cholecystectomy for chronic biliary dyspepsia where repeat ultrasonography fails to demonstrate a gallbladder. PMID:23401761

    Thirty patients with chronic upper abdominal pain and no evidence of cholelithiasis were entered into this study. All had negative ultrasonography of the gallbladder, and most had a host of other negative investigations. These patients were referred to a surgeon to evaluate the possibility of atypical biliary colic associated with chronic acalculous cholecystitis. All patients underwent cholecystokinin-stimulated cholescintigraphy and were offered cholecystectomy if the ejection fraction was less than 35 per cent. Of the 30 patients, 27 (90%) had pathologically abnormal gallbladders. Follow-up averaged over 1 year (13.2 mo), and relief of symptoms occurred in 28 (94%). The authors conclude that in appropriately selected patients with symptoms of biliary colic (typical or atypical) and no evidence of cholelithiasis, a cholecystokinin-stimulated cholescintigram is a significant help in predicting not only which patients have gallbladder disease, but also how likely cholecystectomy is to result in an improvement in their symptoms.

    2014-09-01

    Diagnosis of biliary atresia (BA) in infants presenting with cholestatic jaundice (CJ) requires exploratory surgery with cholangiography. However, the lack of a standardized approach to preoperative evaluation of infants with CJ can lead to a high number of negative surgical explorations. We reviewed our experience with CJ and BA to determine preoperative variables that might reliably identify BA. Infants explored for possible BA over a 5-year period were retrospectively reviewed. Preoperative clinical indices and liver biopsy results were reviewed. Statistical analysis was conducted by Student's t test and Fisher's exact test (P < 0.05). Twenty patients were identified, 10 with BA and 10 without (50% negative exploration rate). Nuclear cholescintigraphy (HIDA) excretion into the gastrointestinal tract was absent in all BA and in 8 of 10 without BA. Hepatomegaly was more common in the BA group (OR = 9.3, P = 0.07). BA had higher mean (± standard error) serum gamma-glutamyl transpeptidase levels (542 ± 130 vs 139 ± 25.8 U/L in non-BA, P = 0.03). There were insignificant differences in sex, type of feeding, TPN exposure and sepsis between the two groups. Although our small sample size limits conclusions, we suggest screening infants with CJ by measuring GGT levels, absence of hepatomegaly, presence of cholic stools and/or excretion on HIDA scan to undergo pecutaneous liver biopsy given the lower likelihood of BA necessary.

    Liver granulomas and elevated serum IgM are commonly observed in patients with primary biliary cirrhosis (PBC) but their pathogenetic significance remains largely unknown. To address this issue we performed an extensive immunostaining and colocalization study of markers associated with dendritic cells and IgM in a large cohort of tissue samples from PBC and control livers as well as from non-hepatic granulomatous diseases. First, the classical dendritic cell CD11c marker is highly expressed and more sensitive than classical hematoxylin-eosin staining in detecting granulomas associated with PBC and other conditions. Second, PBC cases with CD11c-positive granulomas have significantly higher serum IgM levels and earlier disease stages. Third, granulomas from PBC and other diseases demonstrate markers of dendritic cell immaturity, i.e. CD11b, reduced MHC II, IL-23, CCR7 and CD83 expression, and elevated C1q expression. Lastly, B cells and IgM-positive plasma cells are largely represented around PBC granulomas along with macrophages. In conclusion, our comprehensive immunohistochemical study suggests that dendritic cells are key to the pathogenesis of granulomas, regardless of their origin. More specifically, PBC liver granulomas may result from the interaction between immature dendritic cells and IgM.

    2015-07-07

    Primary biliary cirrhosis (PBC) is a chronic progressive cholestatic granulomatous, and destructive inflammatory lesion of small intralobular and septal bile ducts, which is likely to be caused by an autoimmune mechanism with a the presence of serum antimitochondrial antibodies and a potential tendency to progress to cirrhosis. Despite the fact that the etiology of this disease has been unknown so far, there has been a considerable body of scientific evidence that can reveal the clinical and laboratory signs of PBC and the individual components of its pathogenesis and elaborate diagnostic criteria for the disease and its symptomatic therapy. Deficiencies in autoimmune tolerance are critical factors for the initiation and perpetuation of the disease. The purpose of this review is to summarize the data available in the literature and the author's findings on clinical and laboratory criteria for the diagnosis of PBC. This review describes the major clinical manifestations of the disease and the mechanisms of its development. It presents the immunological, biochemical, and morphological signs of PBC and their significance for its diagnosis. A great deal of novel scientific evidence for the problem of PBC has been accumulated. However, the inadequate efficiency of therapy for the disease lends impetus to the quest for its etiological factors and to further investigations of its pathogenetic mechanisms and, on this basis, to searches for new methods for its early diagnosis.

    2016-01-01

    Data from genome wide association studies and geoepidemiological studies established that a combination of genetic predisposition and environmental stimulation is required for the loss of tolerance in primary biliary cholangitis (PBC). The serologic hallmark of PBC are the presence of high titer anti-mitochondrial autoantibodies (AMA) that recognize the lipoyl domain of the mitochondrial pyruvate dehydrogenase E2 (PDC-E2) subunit. Extensive efforts have been directed to investigate the molecular basis of AMA. Recently, experimental data has pointed to the thesis that the breaking of tolerance to PDC-E2 is a pivotal event in the initial etiology of PBC, including environmental xenobiotics including those commonly found in cosmetics and food additives, suggesting that chemical modification of the PDC-E2 epitope may render its vulnerable to become a neo-antigen and trigger an immune response in genetically susceptible hosts. Here, we will discuss the natural history, genetics and immunobiology of PBC and structural constraints of PDC-E2 in AMA recognition which makes it vulnerable to chemical modification. PMID:26755880

    2013-01-01

    Primary biliary cirrhosis (PBC) has been often coined a model autoimmune disease based on the homogeneity amongst patients, the frequency and similarity of antimitochondrial antibodies, including the highly directed immune response to pyruvate dehydrogenase (PDC-E2). A significant number of patients with PBC suffer from sicca and amongst these, there are patients who also have classic Sjogren's syndrome. Indeed, both PBC and Sjogren's syndrome are characterized by inflammation of target epithelial elements. Both diseases can be considered on the basis of a number of other related clinical aspects, including proposed unique apoptotic features of the target tissue, the role of secretory IgA, and the frequency with which both diseases overlap with each other. Indeed, PBC may be considered a Sjogren's syndrome of the liver, whereas Sjogren's syndrome can be equally discussed as PBC of the salivary glands. Dissection of the genetic predispositions for both diseases and especially the molecular basis of effector mechanisms, will become critical elements in developing new therapies. PMID:22178199

    Antimitochondrial antibodies are the serological hallmark of primary biliary cirrhosis (PBC). Besides antimitochondrial antibodies, the autoantibody profile of PBC includes antinuclear antibodies (ANA) which are detectable by indirect immunofluorescence in up to 50% of PBC patients. Two immunofluorescence patterns are considered 'PBC-specific': the multiple nuclear dots and rim-like/membranous patterns. The target antigens of the multiple nuclear dots pattern have been identified as Sp100 and promyelocytic leukemia protein, whereas the rim-like/membranous pattern is given by autoantibodies recognizing multiple proteins such as gp210, nucleoporin p62 and the lamin B receptor. Other ANA, especially those already known in the rheumatological setting, such as anticentromere, anti-SSA/Ro and anti-dsDNA antibodies, can be frequently found in PBC, often coexisting in the same patient. In this article, we will report on recent progress in the antigenic characterization of ANA in PBC, their detection with both traditional assays and Western blot/ELISA with molecularly defined nuclear antigens, and we will discuss their clinical significance.

    Primary biliary cirrhosis (PBC) is an organ-specific autoimmune disease that predominantly affects women and is characterized by chronic progressive destruction of small intrahepatic bile ducts with portal inflammation and ultimately fibrosis. The serologic hallmark of PBC is the presence of antibodies to mitochondria, especially to the E2 component of the pyruvate dehydrogenase complex. The mechanisms by which (and if) such antibodies produce liver tissue injury are unknown. However, the presence of these antibodies has allowed detailed immunological definition of the antigenic epitopes, the nature of reactive autoantibodies and the characterization of T-cell responses. Several mechanisms may now be proposed regarding the immune-mediated bile duct damage in PBC, including the possible role of T-cell-mediated cytotoxicity and intracellular interaction between the IgA class of antimitochondrial antibodies and mitochondrial autoantigens. There are major questions which remain unanswered, including, of course, etiology, but also the reasons for female predominance, the absence of PBC in children, the relative ineffectiveness of immunosuppressive drugs, and the specific role of mitochondrial antigens. The data so far provide suggestive evidence that PBC is a mucosal disease; this thesis provides a basis for discussion of etiology via the enterohepatic circulation of toxins and/or infection.

    Currently, there is no validated therapeutic target for biliary tract cancer (BTC). This study aimed to investigate the pre-clinical and clinical implication of HER2 as a therapeutic target in BTC. We established two novel HER2-amplified BTC cell lines, SNU-2670 and SNU-2773, from gallbladder cancer patients. SNU-2670 and SNU-2773 cells were sensitive to trastuzumab, dacomitinib, and afatinib compared with nine HER2-negative BTC cell lines. Dacomitinib and afatinib led to G1 cell cycle arrest in SNU-2773 cells and apoptosis in SNU-2670 cells. Furthermore, dacomitinib, afatinib, and trastuzumab showed synergistic cytotoxicity when combined with some cytotoxic drugs including gemcitabine, cisplatin, paclitaxel, and 5-fluorouracil. In a SNU-2670 mouse xenograft model, trastuzumab demonstrated a good anti-tumor effect as a monotherapy and in combination with gemcitabine increasing apoptosis. In our clinical data, 13.0% of patients with advanced BTC were defined as HER2-positive. Of these, three patients completed HER2-targeted chemotherapy. Two of them demonstrated a partial response, and the other one showed stable disease for 18 weeks. In summary, these pre-clinical and clinical data suggest that HER2 could be a therapeutic target, and that a HER2-targeting strategy should be developed further in patients with HER2-positive advanced BTC.

    Biliary tract cancers (BTCs) are relatively uncommon orphan tumors that have an aggressive disease course and a poor clinical outcome. Surgery is the only curative treatment, but most patients present with advanced disease and therefore have a limited survival. Gemcitabine and cisplatin based chemotherapy has been the only widely accepted standard systemic therapy regimen in these patients but these tumors can be chemoresistant, further complicating their management. In recent times, there has been considerable research in the genetics of BTC and with the advent of new, advanced technologies like next-generation sequencing (NGS) we are achieving a greater understanding of its disease biology. With the help of NGS, we have now been able to identify actionable mutations such as in the isocitrate dehydrogenase 1 (IDH1), FGFR2, BRAF and HER2/neu genes for targeted therapeutics and correlate the genetic variations with distinct clinical prognoses. This recent genetic information has the potential to make precision medicine a part of routine clinical practice for the management of BTC patients. PMID:27747093

  2. Pancreatitis of biliary origin, optimal timing of cholecystectomy (PONCHO trial): study protocol for a randomized controlled trial

    PubMed Central

    2012-01-01

    Background After an initial attack of biliary pancreatitis, cholecystectomy minimizes the risk of recurrent biliary pancreatitis and other gallstone-related complications. Guidelines advocate performing cholecystectomy within 2 to 4 weeks after discharge for mild biliary pancreatitis. During this waiting period, the patient is at risk of recurrent biliary events. In current clinical practice, surgeons usually postpone cholecystectomy for 6 weeks due to a perceived risk of a more difficult dissection in the early days following pancreatitis and for logistical reasons. We hypothesize that early laparoscopic cholecystectomy minimizes the risk of recurrent biliary pancreatitis or other complications of gallstone disease in patients with mild biliary pancreatitis without increasing the difficulty of dissection and the surgical complication rate compared with interval laparoscopic cholecystectomy. Methods/Design PONCHO is a randomized controlled, parallel-group, assessor-blinded, superiority multicenter trial. Patients are randomly allocated to undergo early laparoscopic cholecystectomy, within 72 hours after randomization, or interval laparoscopic cholecystectomy, 25 to 30 days after randomization. During a 30-month period, 266 patients will be enrolled from 18 hospitals of the Dutch Pancreatitis Study Group. The primary endpoint is a composite endpoint of mortality and acute re-admissions for biliary events (that is, recurrent biliary pancreatitis, acute cholecystitis, symptomatic/obstructive choledocholithiasis requiring endoscopic retrograde cholangiopancreaticography including cholangitis (with/without endoscopic sphincterotomy), and uncomplicated biliary colics) occurring within 6 months following randomization. Secondary endpoints include the individual endpoints of the composite endpoint, surgical and other complications, technical difficulty of cholecystectomy and costs. Discussion The PONCHO trial is designed to show that early laparoscopic cholecystectomy

    Biliary reconstruction continues to be a major source of morbidity following liver transplantation. The spectrum of biliary complications is evolving due to the increasing number of split-liver and living-donor liver transplantation, which are even associated with a higher incidence of biliary complications. Bile duct strictures are the most common cause of late biliary complications and account for up to 40% of all biliary complications. Optimal therapy for posttransplantation anastomotic biliary strictures remains uncertain and requires a multidisciplinary approach. We report the case of a 54-year-old Caucasian male affected by hepatocarcinoma and hepatitis C-related cirrhosis who underwent right-lobe living-donor liver transplantation from his son complicated by double anastomotic stenosis of the main right hepatic duct and of an accessory biliary duct draining segments 6 and 7 of the graft that was successfully treated by percutaneous transhepatic cholangiography with long-term subcutaneous placement of two internal Ruesch-type biliary stents.

    Chronic postoperative pain remains a frequent pathology whose global impact approximates 20 and 30% and accounts for 20% of the consultations in a pain center. Risk factors consider firstly each patient's feature and comorbidity and also different surgical procedures with their technical approach. Neuropathic pain compared to nociceptive pain is a great component in the postoperative period and needs to be recognized by specific tests (DN4). Pain prevention involves risk factors' detection, appropriate anesthetic support and effective postoperative pain management. Treatment is based on the type of pain and includes a multimodal analgesia with interventional pain therapy.

    It is difficult to detect pancreatic cancer or biliary-tract cancer at an early stage using current diagnostic technology. Utilizing microRNA (miRNA) markers that are stably present in peripheral blood, we aimed to identify pancreatic and biliary-tract cancers in patients. With "3D-Gene", a highly sensitive microarray, we examined comprehensive miRNA expression profiles in 571 serum samples obtained from healthy patients, patients with pancreatic, biliary-tract, or other digestive cancers, and patients with non-malignant abnormalities in the pancreas or biliary tract. The samples were randomly divided into training and test cohorts, and candidate miRNA markers were independently evaluated. We found 81 miRNAs for pancreatic cancer and 66 miRNAs for biliary-tract cancer that showed statistically different expression compared with healthy controls. Among those markers, 55 miRNAs were common in both the pancreatic and biliary-tract cancer samples. The previously reported miR-125a-3p was one of the common markers; however, it was also expressed in other types of digestive-tract cancers, suggesting that it is not specific to cancer types. In order to discriminate the pancreato-biliary cancers from all other clinical conditions including the healthy controls, non-malignant abnormalities, and other types of cancers, we developed a diagnostic index using expression profiles of the 10 most significant miRNAs. A combination of eight miRNAs (miR-6075, miR-4294, miR-6880-5p, miR-6799-5p, miR-125a-3p, miR-4530, miR-6836-3p, and miR-4476) achieved a sensitivity, specificity, accuracy and AUC of 80.3%, 97.6%, 91.6% and 0.953, respectively. In contrast, CA19-9 and CEA gave sensitivities of 65.6% and 40.0%, specificities of 92.9% and 88.6%, and accuracies of 82.1% and 71.8%, respectively, in the same test cohort. This diagnostic index identified 18/21 operable pancreatic cancers and 38/48 operable biliary-tract cancers in the entire cohort. Our results suggest that the assessment of

    Organ-specific and systemic autoimmune diseases share numerous features and often coexist in the same patient. Autoimmune cholangitis/primary biliary cirrhosis and Sjogren syndrome represent paradigmatic examples of the common grounds of different autoimmunity phenotypes based on similarities in clinical manifestations and immunopathogenesis. In fact, primary biliary cirrhosis and Sjogren's syndrome have both been coined as an autoimmune epithelitis in which apoptosis may be in both cases the key element to explain the organ-specific immune-mediated injury against the biliary and exocrine gland epithelia, respectively. Further, growing evidence supports in both diseases the view that B cells, T cytotoxic cells, and T helper cells are involved in chronic inflammation, likely via the altered expression of pro-inflammatory cytokines. The presence of estrogen receptors on the biliary and exocrine gland epithelia has been advocated as a key to the female predominance encountered in primary biliary cirrhosis and Sjogren's syndrome. Sadly, despite available data, therapeutic approaches remain largely unsatisfactory and recent studies with mechanistic approaches (as in the case of B cell depletion with rituximab) have been of partial benefit only. Future studies should focus on new molecular tools (single-cell transcriptomics, microRNA, epigenetics) to provide unique insights into common mechanisms.

    Twenty-two patients with malignant biliary obstruction and 21 patients with suspected obstruction of biliary-enteric anastomoses were evaluated over a 12-month period with magnetic resonance (MR) cholangiography and cross-sectional MR imaging. In patients with malignant obstruction, MR cholangiography helped accurately determine the status of the biliary ductal system by identifying the exact location and extent of the obstruction and the severity of duct dilatation. In so doing, MR cholangiography helped determine whether percutaneous transhepatic cholangiography with antegrade stent placement or retrograde cholangiography with stent placement constituted the more suitable treatment. Cross-sectional MR imaging was necessary to identify the organ of tumor origin, define the tumor margins, and determine the stage of disease. This information helped evaluate the appropriateness of curative surgical therapy versus palliative drainage procedures. In patients with biliary-enteric anastomoses, MR cholangiography clearly depicted the site of the anastomosis and demonstrated the status of the intrahepatic ducts, thereby helping determine which patients would benefit from undergoing antegrade duct cannulation with a drainage procedure or perhaps balloon dilation. In some of these patients, MR cholangiography was sufficient to help plan therapeutic intervention. MR cholangiography also demonstrates the presence and size of biliary stones and associated findings such as intraductal tumor growth. In addition, MR cholangiography may obviate retrograde cholangiography, which can be technically difficult to perform.

    Dynamic remodeling of the intrahepatic biliary epithelial tissue plays key roles in liver regeneration, yet the cellular basis for this process remains unclear. We took an unbiased approach based on in vivo clonal labeling and tracking of biliary epithelial cells in the three-dimensional landscape, in combination with mathematical simulation, to understand their mode of proliferation in a mouse liver injury model where the nascent biliary structure formed in a tissue-intrinsic manner. An apparent heterogeneity among biliary epithelial cells was observed: whereas most of the responders that entered the cell cycle upon injury exhibited a limited and tapering growth potential, a select population continued to proliferate, making a major contribution in sustaining the biliary expansion. Our study has highlighted a unique mode of epithelial tissue dynamics, which depends not on a hierarchical system driven by fixated stem cells, but rather, on a stochastically maintained progenitor population with persistent proliferative activity.

    Biliary atresia is the most common cause of end-stage liver disease in the infant and is the leading pediatric indication for liver transplantation in the United States. Earlier diagnosis (<30-45 days of life) is associated with improved outcomes following the Kasai portoenterostomy and longer survival with the native liver. However, establishing this diagnosis is problematic because of its rarity, the much more common indirect hyperbilirubinemia that occurs in the newborn period, and the schedule for routine infant health care visits in the United States. The pathogenesis of biliary atresia appears to involve immune-mediated fibro-obliteration of the extrahepatic and intrahepatic biliary tree in most patients and defective morphogenesis of the biliary system in the remainder. The determinants of the outcome of portoenterostomy include the age at surgery, the center's experience, the presence of associated congenital anomalies, and the postoperative occurrence of cholangitis. A number of screening strategies in infants have been studied. The most promising are early measurements of serum conjugated bilirubin and a stool color card given to new parents that alerts them and their primary care provider to acholic stools. This report summarizes a National Institutes of Health workshop held on September 12 and 13, 2006, in Bethesda, MD, that addressed the issues of outcomes, screening, and pathogenesis of biliary atresia.

    Aberrant transcriptional regulation contributes to the pathogenesis of both congenital and adult forms of liver disease. Although the transcription factor RBPJ is essential for liver morphogenesis and biliary development, its specific function in the differentiation of hepatic progenitor cells (HPC) has not been investigated, and little is known about its role in adult liver regeneration. HPCs are bipotent liver stem cells that can self-replicate and differentiate into hepatocytes or cholangiocytes in vitro. HPCs are thought to play an important role in liver regeneration and repair responses. While the coordinated repopulation of both hepatocyte and cholangiocyte compartment is pivotal to the structure and function of the liver after regeneration, the mechanisms coordinating biliary regeneration remain vastly understudied. Here, we utilized complex genetic manipulations to drive liver-specific deletion of the Rbpj gene in conjunction with lineage tracing techniques to delineate the precise functions of RBPJ during biliary development and HPC-associated biliary regeneration after hepatectomy. Furthermore, we demonstrate that RBPJ promotes HPC differentiation toward cholangiocytes in vitro and blocks hepatocyte differentiation through mechanisms involving Hippo-Notch crosstalk. Overall, this study demonstrates that the Notch-RBPJ signaling axis critically regulates biliary regeneration by coordinating the fate decision of HPC and clarifies the molecular mechanisms involved.

    The results of treatment of 56 patients, in whom in 1984-2010 yrs, while performing cholecystectomy, a biliary duct injury have occurred, were analyzed, including 26 (main group)--with combined injury of biliary ducts and brunches of common hepatic artery, 30 (control group)--with isolated complete biliary ducts. High hepaticojejunostomy have constituted the main method of operation in a control group. In the main group in 2 patients there were attempts made to restore the arterial blood flow with subsequent performance of reconstructive intervention on biliary ducts. In 16 (61.5%) patients, due to adequate collateral blood supply presence, the bile outflow was restored using hepaticojejunostomy formation, and in 8 (30.8%)--hepatic resection of various volume was needed, because of hepatic abscesses formation. The results of treatment of patients in these groups have differed not essentially, while applying differentiated approach (positive results were achieved in 93.3 and 84.6% of patients, accordingly). So, in patients with combined injury of biliary ducts and branches of hepatic artery, while performance of cholecystectomy, it is necessary to apply multimodal tactics of treatment, taking into account the peculiarities of clinical course.

    The effect of normothermic machine perfusion (NMP) on post-reperfusion hemodynamics and extrahepatic biliary duct histology of donors after cardiac death (DCD) livers after transplantation has not been addressed thoroughly and represented the object of this study. Ten livers (n=5/group) with 60’ of warm ischemia were preserved by cold storage (CS) or sanguineous NMP for 10 hours, and then reperfused for 24 hours with whole blood in an isolated perfusion system to simulate transplantation. In our experiment, arterial and portal venous flows were stable in NMP group during the entire simulated reperfusion, while decreased dramatically in CS group after 16 hours post-reperfusion (P<.05), findings consistent with severe parenchymal injury. Similarly, significant differences existed between CS and NMP group on hepatocellular enzyme release, bile volume produced, and enzyme released into bile (P<.05). On histology CS livers presented with diffuse hepatocyte congestion, necrosis, intraparenchymal hemorrhage, denudated biliary epithelium and submucosal bile duct necrosis, while NMP liver showed very mild injury in liver parenchyma and biliary architecture. Most importantly, Ki67 staining in extrahepatic bile duct showed biliary epithelial regeneration. Our findings advance the knowledge of post-reperfusion events that characterize DCD livers and propose NMP as a beneficial preservation modality able to improve biliary regeneration after a major ischemic event, which may prevent in clinical transplantation the development of ischemic cholangiopathy.

    Endoscopic manometry was used to measure pancreatic duct, common bile duct, pancreatic duct sphincter and bile duct sphincter pressures in 43 healthy volunteers and 162 patients with a variety of papillary, pancreatic and biliary disorders. Common bile duct pressure was significantly raised after cholecystectomy, with common bile duct stones and papillary stenosis but pancreatic duct pressure only in papillary stenosis. After endoscopic sphincterotomy mean common bile duct pressure fell from 11.2 to 1.1 mmHg and pancreatic duct pressure from 18.0 to 11.2 mmHg. Distinct pancreatic duct sphincter and bile duct sphincter zones were identified as phasic pressures of 3-12 waves/minute on pull-through from pancreatic duct and common bile duct to duodenum. Pancreatic duct sphincter pressures were higher with common bile duct stones and stenosis whereas bile duct sphincter pressures were higher in pancreatitis and stenosis. Bile duct sphincter activity was present in 60% of patients after surgical sphincteroplasty but 21% of patients after endoscopic sphincterotomy. Endoscopic manometry facilitated the diagnosis of papillary stenosis, has allowed study of papillary pathophysiology and has shown a functional inter-relationship between the two sphincteric zones.

    In the postoperative period, 47% to 75% of the patients report some degree of pain. This study aimed to evaluate pain in the pre and postoperative period of patients submitted to craniotomy. This prospective research was carried out at the neurosurgery unit of a large Brazilian hospital. For a quantitative evaluation of pain, the verbal numeric 0-10 rating scale was used. Forty patients with a mean age of 36 years were evaluated. In the preoperative period, 34 (85%) patients indicated headache as the main cause of pain. In the postoperative period, 37 (93%) patients complained of pain while three (7%) reported absence of pain. Pain peaks were observed on the 2nd postoperative day, when 12 (32%) of the patients reported severe pain and 10 (27%) moderate pain. Absence of severe pain occurred after the 8th postoperative day. It was concluded that protocols of analgesia in craniotomy are needed, such as training nurses to better evaluate and handle pain.

    Multiple lines of evidence suggest an increased sensitivity to pain in neonates. Repeated and prolonged pain exposure may affect the subsequent development of pain systems, as well as potentially contribute to alterations in long-term development and behavior. Despite impressive gains in the knowledge of neonatal pain mechanisms and strategies to treat neonatal pain acquired during the last 15 years, a large gap still exists between routine clinical practice and research results. Accurate assessment of pain is crucial for effective pain management in neonates. Neonatal pain management should rely on current scientific evidence more than the attitudes and beliefs of care-givers. Parents should be informed of pain relief strategies and their participation in the health care plan to alleviate pain should be encouraged. The need for systemic analgesia for both moderate and severe pain, in conjunction with behavioral/environmental approaches to pain management, is emphasized. A main sources of pain in the neonate is procedural pain which should always be prevented and treated. Nonpharmacological approaches constitute important treatment options for managing procedural pain. Nonpharmacological interventions (environmental and preventive measures, non-nutritive sucking, sweet solutions, skin-skin contact, and breastfeeding analgesia) can reduce neonatal pain indirectly by reducing the total amount of noxious stimuli to which infants are exposed, and directly, by blocking nociceptive transduction or transmission or by activation of descending inhibitory pathways or by activating attention and arousal systems that modulate pain. Opioids are the mainstay of pharmacological pain treatment but there are other useful medications and techniques that may be used for pain relief. National guidelines are necessary to improve neonatal pain management at the institutional level, individual neonatal intensive care units need to develop specific practice guidelines regarding pain

    Background In 2013, an unusually high incidence of biliary tract cancer among current or former workers of the offset color proof printing department of a printing company in Osaka, Japan, was reported. The purpose of this study was to examine whether distance from the printing factory was associated with incidence of biliary tract cancer and whether incident biliary tract cancer cases clustered around the printing factory in Osaka using population-based cancer registry data. Methods We estimated the age-standardized incidence ratio of biliary tract cancer according to distance from this printing factory. We also searched for clusters of biliary tract cancer incidence using spatial scan statistics. Results We did not observe statistically significantly high or low standardized incidence ratios for residents in each area categorized by distance from the printing factory for the entire sample or for either sex. The scan statistics did not show any statistically significant clustering of biliary tract cancer incidence anywhere in Osaka prefecture in 2004–2007. Conclusions There was no statistically significant clustering of biliary tract cancer incidence around the printing factory or in any other areas in Osaka, Japan, between 2004 and 2007. To date, even if some substances have diffused outside this source factory, they do not appear to have influenced the incidence of biliary tract cancer in neighboring residents. PMID:26902168

    A 32-year-old woman presented with epigastric pain. She was a patient with chronic pain syndrome and had visited the emergency department several times over the past year. She did not drink alcohol. She had a laparoscopic cholecystectomy for gallstone pancreatitis 4 years ago. Her lipase was 2020 with normal bilirubin. MR cholangiopancreatography revealed a cystic structure resembling a gallbladder in the gallbladder fossa. This was in connection with the biliary system. The structure also contained stones. A review of the histology did confirm the gallbladder had been removed. She proceeded to have a laparoscopic re-cholecystectomy and made an unremarkable recovery.

  3. Gut-liver axis: an immune link between celiac disease and primary biliary cirrhosis.

    PubMed

    2013-03-01

    The association between celiac disease and primary biliary cirrhosis is well established. The breakdown of gut-liver axis equilibrium plays a central role in the development of immune disorders involving the small bowel and liver. In celiac disease, immunologically active molecules generated from the cross-linking between tissue transglutaminase and food/bacterial antigens reach the liver through the portal circulation owing to the increased intestinal permeability. A molecular mimicry between bacterial antigens and the pyruvate dehydrogenase E2 component, recognized by antimitochondrial autoantibodies, may have a role in primary biliary cirrhosis pathogenesis. An aberrant intestinal T lymphocyte homing to the liver may contribute to trigger immune hepatic damage. Both celiac disease and primary biliary cirrhosis share several features, including a higher prevalence in females, autoimmune comorbidities and specific autoantibodies. Reciprocal screening for both diseases is recommended, as an early diagnosis with the appropriate treatment can improve the outcome of these patients.

    Hepatobiliary cystadenomas (HBC) is a rare neoplasm which comprising less than one percent of liver cystic neoplasms. Although it’s known as a benign tumor, but they have a potential for neoplastic transformation. Making a proper diagnosis and ruling out of other differential diagnosis is important because of different treatment. In the present study, we described a case of HBC manifested as idiopathic dominant biliary stricture in common hepatic duct (CHD), on the basis of spiral CT scan and MRI, and elevated CA19-9. With a probable diagnosis of malignant biliary stricture, she underwent ERCP and cholangioscopy that were non-diagnostic and final diagnosis was made surgically. HBCs usually found incicentally as a cystic lesion and biliary stricture without visible cyst in imaging like that seen in cholangiocarcinoma is very unlikely. In truth, this patient is an unusual manifestation of one rare disease. PMID:28224034

    Most biliary stone diseases need to be treated surgically. However, in special cases that traditional biliary tract endoscopic access is not allowed, a multidisciplinary approach using hybrid technique with urologic instrumental constitute a treatment option. We report a case of a patient with complex intrahepatic stones who previously underwent unsuccessful conventional approaches, and who symptoms resolved after treatment with hybrid technique using an endourologic technology. We conducted an extensive literature review until October 2012 of manuscripts indexed in PubMed on the treatment of complex gallstones with hybrid technique. The multidisciplinary approach with hybrid technique using endourologic instrumental represents a safe and effective treatment option for patients with complex biliary stone who cannot conduct treatment with conventional methods.

    Biliary stenosis is a common complication after liver transplantation, and has an incidence rate ranging from 4.7% to 12.5% based on our previous study. Three types of biliary stenosis (anastomotic stenosis, non-anastomotic peripheral stenosis and non-anastomotic central hilar stenosis) have been identified. We report the outcome of two patients with anastomotic stricture after liver transplantation who underwent successful cutting balloon treatment. Case 1 was a 40-year-old male transplanted due to subacute fulminant hepatitis C. Case 2 was a 57-year-old male transplanted due to hepatitis B virus-related end-stage cirrhosis associated with hepatocellular carcinoma. Both patients had similar clinical scenarios: refractory anastomotic stenosis after orthotopic liver transplantation and failure of balloon dilation of the common bile duct to alleviate biliary stricture.

  7. Chlordecone impaired biliary excretion: In vivo and in vitro correlates

    SciTech Connect

    Rochelle, L.G.

    1989-01-01

    The focus of this research was to investigate mechanisms of impaired biliary excretion localized to the bile canaliculus. Two modes of chlordecone (CD) action were investigated: (1) direct effects on organic anion transport at the bile canaliculus; and/or (2) general membrane perturbation, indirectly affecting anion transport proteins. Bile canaliculi-enriched fractions (BCEF) were isolated from rat livers in order to characterize effects of CD on this domain of the plasma membranes. CD inhibited the initial rate leading to a peak Na{sup +}-stimulated ({sup 3}H)L-glutamate uptake in BCEF CD inhibition of the initial or Na{sup +}-gradient driven phase of ({sup 3}H)L-glutamate uptake suggested that CD was affecting maintenance of the Na{sup +}-gradient by the BCEF membrane vesicles. In vivo PG anion excretion was inhibited as well as in vitro ({sup 3}H)L-glutamate transport at 24 hr following in vivo CD treatment of rats. Seventy-two hr following CD treatment, rats recovered to control PG excretion levels. PG excretory performance was regained in 72 hr pretreated rats despite an increase in liver CD concentration. Liver CD concentrations in 24 hr pretreated rats were approximately 50% of the concentrations in 72 hr pretreated rats. At low CD concentrations, there was no evidence of general membrane perturbation in terms of immobilization of the lipid electron spin resonance probe, 16-doxyl stearate, in BCEF. Mobility of 16-doxyl stearate in BCEF was reduced at in vitro CD concentrations of 0.20 {mu}mol/mg protein or greater. CD did reduce hepatobiliary permeability to ({sup 14}C)mannitol in 24 and 72 hr pretreated rats; perhaps restricting movement through membrane aqueous pores.

    Background/Purpose: This study aims to analyze the incidence and type of various associated anomalies among infants with extrahepatic biliary atresia (EHBA), compare their frequency with those quoted in the existing literature and assess their role in the overall management. Materials and Methods: A retrospective study was performed on 137 infants who underwent the Kasai procedure for EHBA during the past 12 years. The medical records were reviewed for the incidence and type of associated anomalies in addition to the details of the management of the EHBA. Results: Of the137 infants, 40 (29.2%) were diagnosed as having 58 anomalies. The majority of patients had presented in the 3rd month of life; mean age was 81 ± 33 days (range = 20-150 days). There were 32 males and 8 females; boys with EHBA had a higher incidence of associated anomalies. Of these 40 patients, 22 (37.9%) had vascular anomalies, 13 patients (22.4%) had hernias (umbilical-10, inguinal-3), 7 patients (12.1%) had intestinal malrotation, 4 patients (6.8%) had choledochal cyst, 1 patient (1.7%) had Meckel's diverticulum, 3 patients (5%) had undergone prior treatment for jejunoileal atresias (jejunal-2, ileal-1), 2 patients (3.4%) had undergone prior treatment for esophageal atresia and tracheoesophageal fistula, 2 patients (3.4%) had spleniculi, and 2 patients (3.4%) were diagnosed as having situs inversus. Conclusions: The most common associated anomalies in our study were related to the vascular variation at the porta hepatis and the digestive system. The existence of anomalies in distantly developing anatomic regions in patients with EHBA supports the possibility of a “generalized” insult during embryogenesis rather than a “localized” defect. In addition, male infants were observed to have significantly more associated anomalies as compared with the female infants in contrast to earlier reports. PMID:26862288

  9. Primary biliary cirrhosis: Pathophysiology, clinical presentation and therapy

    PubMed Central

    Purohit, Treta; Cappell, Mitchell S

    2015-01-01

    Primary biliary cirrhosis (PBC) is an autoimmune, slowly progressive, cholestatic, liver disease characterized by a triad of chronic cholestasis, circulating anti-mitochondrial antibodies (AMA), and characteristic liver biopsy findings of nonsuppurative destructive cholangitis and interlobular bile duct destruction. About 10% of PBC patients, however, lack AMA. A variant, called PBC-autoimmune hepatitis (AIH) overlap, is characterized by the above findings of PBC together with findings of elevated serum alanine aminotransferase, elevated serum immunoglobulin G, and circulating anti-smooth muscle antibodies, with liver biopsy demonstrating periportal or periseptal, lymphocytic, piecemeal necrosis. PBC is hypothesized to be related to environmental exposure in genetically vulnerable individuals. It typically occurs in middle-aged females. Prominent clinical features include fatigue, pruritis, jaundice, xanthomas, osteoporosis, and dyslipidemia. The Mayo Risk score is the most widely used and best prognostic system. Ursodeoxycholic acid is the primary therapy. It works partly by reducing the concentration and injury from relatively toxic bile acids. PBC-AIH overlap syndrome is treated with ursodeoxycholic acid and corticosteroids, especially budesonide. Obeticholic acid and fibrate are promising new, but incompletely tested, therapies. Liver transplantation is the definitive therapy for advanced disease, with about 70% 10-year survival after transplantation. Management of pruritis includes local skin care, dermatologist referral, avoiding potential pruritogens, cholestyramine, and possibly opioid antagonists, sertraline, or rifaximin. Management of osteoporosis includes life-style modifications, administration of calcium and vitamin D, and alendronate. Statins are relatively safe to treat the osteopenia associated with PBC. Associated Sjogren’s syndrome is treated by artificial tears, cyclosporine ophthalmic emulsion to stimulate tear production; and saliva

    Biliary obstructive jaundice (OJ) is an important clinical consideration concerning high bacteremic risk. Hepatocyte apoptosis is one of the causes of cholestatic liver injury. The aim of the current study was to examine the precise pathway and time course of hepatocyte apoptosis during OJ with LPS administration and to determine if OJ sensitizes the liver to endotoxemia. Male C57BL/6 mice were subjected to bile duct ligation and division and were administered with LPS at 3 (OJ3) or 14 (OJ14) days after surgery. Fas ligand expression, poly (adenosine diphosphate-ribose) polymerase p85 fragment immunohistochemistry, activation of caspases 3, 8, and 9, serum alanine aminotransferase levels, and hepatic adenosine triphosphate (ATP) contents were examined. Survival after LPS administration in male C57BL/6 or gld/gld (Fas ligand-deficient) mice was determined. The expression of Fas ligand increased during OJ. After LPS administration, the expression of cleaved caspases 3 and 8 increased in Sham3, Sham14, OJ3, and OJ14 mice, and it significantly increased in OJ14 compared with other mice. Poly (adenosine diphosphate-ribose) polymerase p85 immunohistochemistry showed significant hepatocyte apoptosis after LPS administration in OJ14 mice relative to OJ3. In OJ14 with LPS administration, ATP contents significantly decreased and alanine aminotransferase levels increased. Hepatocyte apoptosis was decreased in gld/gld OJ14 mice compared with C57BL/6 OJ14. All C57BL/6 OJ14 mice with LPS died, but survival in gld/gld OJ14 significantly ameliorated. In prolonged OJ with LPS administration, hepatocyte apoptosis depending on Fas ligand expression significantly increased in association with a decrease in ATP contents, thus resulting in liver necrapoptosis.

    1. Prediction of biliary excretion is a challenge due to the lack of in vitro assays. Our laboratory previously demonstrated a highly significant correlation between in vitro IC50 values against mrp2 using rat canalicular liver plasma membrane vesicles and in vivo biliary excretion (Colombo et al., 2012). This study explores the possibility of predicting in vivo biliary excretion in human using membrane vesicles prepared from MDCKII cells transfected with human ABCC2. 2. In vitro MRP2 activity was determined by measuring the ATP-dependent uptake of 5(6)-carboxy-2',7'-dichlorofluorescein (CDCF) in inside-out membrane vesicles isolated from MDCK-ABCC2 cells. CDCF uptake was time- and concentration-dependent (Km of 4.0 ± 1.2 µM and a Vmax of 7.8 ± 0.9 pmol/mg/min) and inhibited by benzbromarone and MK-571 with IC50 values of 1.2 and 7.6 µM, respectively. 3. A significant linear correlation (r(2 )= 0.790) between the in vitro IC50 values from the described MRP2 assay and in vivo biliary excretion in humans was observed using 11 well-documented drugs covering low to high biliary excretions. 4. This study demonstrates, for the first time, that inhibition of CDCF uptake in MDCKII-ABCC2 vesicles not only provides a screening assay to assess MRP2 drug-drug interaction potential, but is also predictive of human MRP2-mediated biliary excretion.

    Highlights: • The RRV infected group showed cholestasis, retardation and extrahepatic biliary atresia. • miR-222 was highly expressed, and PPP2R2A was inhibited in the murine biliary atresia model. • miR-222 profoundly modulated the process of fibrosis in the murine biliary atresia model. • miR-222 might represent a potential target for improving biliary atresia prognosis. - Abstract: microRNA-222 (miR-222) has been shown to initiate the activation of hepatic stellate cells, which plays an important role in the pathogenesis of liver fibrosis. The aim of our study was to evaluate the role of miR-22 in a mouse model of biliary atresia (BA) induced by Rhesus Rotavirus (RRV) infection. New-born Balb/c mice were randomized into control and RRV infected groups. The extrahepatic bile ducts were evaluated. The experimental group was divided into BA group and negative group based on histology. The expression of miR-222, protein phosphatase 2 regulatory subunit B alpha (PPP2R2A), proliferating cell nuclear antigen (PCNA) and phospho-Akt were detected. We found that the experimental group showed signs of cholestasis, retardation and extrahepatic biliary atresia. No abnormalities were found in the control group. In the BA group, miR-222, PCNA and Akt were highly expressed, and PPP2R2A expression was significantly inhibited. Our findings suggest that miR-222 profoundly modulated the process of fibrosis in the murine BA model, which might represent a potential target for improving BA prognosis.

    Disruption of the murine mdr2 gene leads to the complete absence of biliary phospholipids. We tested the hypothesis that the increase in biliary phospholipid output induced by fibrates is mediated via induction of the hepatic mdr2 gene and its encoded product, the P-glucoprotein canalicular flippase. Increased levels of mdr2 mRNA were observed in the liver of mice treated with different fibrates: ciprofibrate, 660+/-155% (as compared with control group); clofibrate, 611+/-77%; bezafibrate, 410+/-47%; fenofibrate, 310+/-52%; gemfibrozil, 190+/-25% (P <0.05 compared with control group). Induction of expression of the mdr gene family was specific to the mdr2 gene. Two- to three-fold increases in P-glycoprotein immunodetection were evident on the canalicular plasma-membrane domain of clofibrate- and ciprofibrate-treated mice. Biliary phospholipid output increased from 4.2+/-1.2 nmol/min per g of liver in the control group to 8.5+/-0.6, 7.1+/-2.9 and 5.8+/-2.5 in ciprofibrate-, clofibrate- and bezafibrate-treated mice respectively (P <0.05 compared with control group). Moreover, a significant correlation between biliary phospholipid output and the relative levels of mdr2 mRNA was found (r=0.86; P <0.05). In treated animals, bile flow as well as cholesterol and bile acid outputs remained unchanged. Our findings constitute the first evidence that pharmacological modulation of biliary lipid secretion mediated by fibrates can be related to the overexpression of a specific liver gene product, the mdr2 P-glycoprotein, and are consistent with the hypothesis that the mdr2 P-glycoprotein isoform plays a crucial role in the secretion of biliary phospholipid.

    OBJECTIVE. The recent experience with U tubes at Rush-Presbyterian-St. Lukes Medical Center was reviewed in order to assess their current role in hepatobiliary surgery. SUMMARY BACKGROUND DATA. Transhepatic intubation by a variety of methods has been used routinely for biliary decompression and inhibition of anastomotic stricture since the 1960s. U tubes were popularized in the early 1970s. However, little has been written about their use and efficacy in recent years. Because of the apparent benefits associated with the use of U tubes versus other stenting techniques, the authors performed this study. METHODS. The hospital and office charts of all patients who had U tubes placed between 1980 and 1992 were reviewed retrospectively. Between 1980 and 1992, U tubes were placed intraoperatively in 54 patients for biliary decompression and/or stenting. Twelve patients were operated on for benign causes of obstruction. Forty-two patients with malignant tumors underwent surgery for U tube placement in conjunction with or without tumor resection and anastomotic bypass. RESULTS. There was a 0% operative mortality rate in the benign group. In six patients, the U tube played a major role in the long-term management of their disease processes. None of these patients has had restricture since removal of the tube. In the malignant group, the 30-day operative mortality rate was 12%. After 3 months, marked clinical improvement and complete biliary decompression were achieved, with mean bilirubin levels dropping from 14.0 mg/dL to 1.3 mg/dL. No patients in the malignant group required reoperation for recurrent biliary obstruction after U tube placement. CONCLUSIONS. The use of U tubes is advocated for biliary decompression and/or anastomotic stenting in patients with benign stricture or resectable malignancy and in patients with nonresectable, malignant biliary obstruction for adequate palliation of intractable jaundice.

    Pain has been considered as part of a defensive strategy whose specific role is to signal an immediate active danger to the organism. This definition fits well for acute pain. It does not work well, however, for chronic pain that is maintained even in absence of an ongoing, active threat. Currently, acute and chronic pain are considered to be separate conditions. What follows is a review of the different theories about pain and its history. Different hypotheses regarding pain mechanisms are illustrated. New data emerging from scientific research on chronic pain (migraine in particular) involving innovative imaging techniques are reported and discussed.

    Hispanic adults experience significant pain, but little is known about their pain during hospitalization. The purpose of this research was to describe Hispanic inpatients' pain intensity and compare their pain intensity with that of non-Hispanic patients. A post hoc descriptive design was used to examine 1,466 Hispanic inpatients' medical records (63.2% English speakers) and 12,977 non-Hispanic inpatients' medical records from one hospital for 2012. Mean documented pain intensity was mild for both Hispanic and non-Hispanic inpatients. Pain intensity was greater for English-speaking Hispanic patients than Spanish speakers. The odds of being documented with moderate or greater pain intensity decreased 30% for Spanish-speaking patients. Greater pain intensity documented for English-speaking Hispanic inpatients suggests underreporting of pain intensity by Spanish-speaking patients. Practitioners should use interpreter services when assessing and treating pain with patients who speak languages different from the practitioners' language(s).

    Primary sclerosing cholangitis (PSC) is a chronic inflammatory disease of the bile ducts with limited therapeutic options except liver transplantation. Reliable biomarkers to predict the disease course are unavailable, and currently employed disease activity scores such as the Mayo risk score (MRS) have limitations. The present study aims to evaluate biliary calprotectin as a marker of disease activity and prognosis in PSC.This is a monocentric retrospective observational study. Calprotectin concentrations were measured by an enzyme-linked immunosorbent assay in bile samples collected by endoscopic retrograde cholangiography from 106 PSC patients and 20 controls. Biliary calprotectin concentrations were compared between the 2 groups. In PSC patients, results were evaluated with regard to the presence of dominant bile duct stenoses, bile microbiology, MRS, survival free of liver transplantation, and necessity for bile duct interventions in the further disease course.Median (interquartile ranges) biliary calprotectin concentrations were higher in PSC patients than in controls (3646 ng/mL, 249-9748 vs 116 ng/mL, 104-655; P < 0.001). In the PSC cohort, higher biliary calprotectin concentrations were associated with the presence of microbes in bile (P = 0.02), the occurrence of dominant bile duct stenosis at any time in the disease course (P = 0.005), and the necessity for future bile duct interventions (P = 0.02). Patients with biliary calprotectin concentrations above a cut-off of 11,610 ng/mL displayed significantly shorter transplantation-free survival than those with biliary calprotectin concentrations ≤11,610 ng/mL (P < 0.001). Univariate Cox regression analysis revealed high biliary calprotectin concentration (>11,610 ng/mL) as a risk factor of shorter transplantation-free survival of PSC patients (P < 0.001) beside high plasma alkaline phosphatase (ALP) concentration (>142.5 U/L) (P = 0.006), high MRS (≥2) (P < 0

    Biliary cirrhosis produced by Campula spp. is described in 1 striped dolphin Stenella coeruleoalba and 4 harbour porpoises Phocoena phocoena. The hepatic lesions consisted of severe proliferation of fibrous connective tissue with loss of the lobular pattern, nodular regeneration of the hepatic tissue, bile duct hyperplasia and severe inflammatory infiltrate composed of eosinophils, macrophages, lymphocytes and plasma cells. These lesions were associated with severe infestation by Campula spp. Although inflammatory and degenerative hepatic lesions are frequently found in stranded dolphins, biliary cirrhosis has not been previously reported in cetaceans. Massive infestation by these parasites should be included as a cause of hepatic failure resulting in stranding of marine mammals.

    We review the discrepancies and the reasons for them, to conclude that clinical findings hold the key to selection of the proper imaging test in biliary obstruction. Cholescintigraphy is a more rewarding approach in detecting low grade obstruction, as by common duct stones, whereas in the patient with prolonged painless jaundice, and the high likelihood of a malignancy, computed tomography or ultrasound will yield the best results. Because of the potential for noninvasive imaging to miss choledocholithiasis and because of ever increasing therapeutic options, direct cholangiography will continue to be the mainstay in definition evaluation of the biliary tract. 12 references.

    A case report of biliary atresia associated with preduodenal portal vein is presented with a review of 27 similar cases previously reported. The occurrence of associated anomalies in these 28 cases has a much higher frequency (82%) than coincidental association. They were associated with cardiovascular anomalies in 71%, polysplenia in 68%, malrotation of the intestine in 61%, situs inversus in 22% and duodenal atresia in 9%. Developmental anomaly is considered to participate strongly in the aetiology of biliary atresia combined with preduodenal portal vein.

    Biliary atresia (BA) is a rare disease and the end result of a destructive, inflammatory cholangiopathy, leading to fibrosis and biliary cirrhosis. It is classified into syndromic variety with various congenital anomalies and non-syndromic (isolated anomaly). We present here a 1-month-old female child with the syndromic variety of BA associated with polysplenia syndrome, dextrocardia, situs inversus totalis and malrotation of intestines. She developed jaundice in the first week of life. Kasai operation was performed but she developed cholangitis and septicemia 2.5 months after surgery and succumbed later. PMID:26023480

    Three patients with postoperative external biliary fistula are described. In each, radionuclide /sup 99m/Tc HIDA was used to define the anatomy of the fistula. The extent of the fistula and the presence of distal obstruction to bile flow could also be determined. This information was used to predict the likelihood of spontaneous fistula closure. HIDA scanning is a useful noninvasive alternative to other investigations, such as fistulography and cholangiography, which do not always provide useful information. The results of HIDA scanning can aid the clinical decision on the need for surgical intervention to correct an external biliary fistula.

    We describe a 33-yr-old pregnant woman in whom a primary biliary cirrhosis-like syndrome developed after 2 wk of chlorpromazine therapy. The clinical course was characterized by severe jaundice lasting 22 mo, intense pruritus, fever, steatorrhea, high alkaline phosphatase levels and hypercholesterolemia. Jaundice resolved with initiation of ursodeoxycholic acid therapy, but subclinical cholestasis and low-level inflammatory activity persisted and ultimately evolved into biliary cirrhosis. The pathological substrate of this severe and prolonged cholestatic reaction was found to be the vanishing bile duct syndrome with a marked transient pseudoxanthomatosis.

    Over the last decade, the clinical applications of contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) have increased steadily. The development of second-generation ultrasound contrast agents has allowed superior visualization of the microvasculature and tissue perfusion of the target lesion. This methodology has proven useful in the differential diagnosis of solid pancreatic masses and lymph nodes. In addition, the applicability of CH-EUS has expanded to nonpancreas structures such as biliary, focal liver lesions, and vascular disease. This article focuses primarily on the novel applications of CH-EUS in biliary tract and visceral vascular diseases. PMID:28218196

    Background and study aims: The treatment success of benign biliary strictures with fully covered metal stents (CSEMS) is altered by high stent dislocation rates. We aimed to evaluate a new stent design to prevent dislocation. Patients and methods: Patients with benign biliary strictures were treated with a newly designed double-coned stent (dcSEMS). Mechanical analysis of the new stent was performed and it was compared with a cylindrical stent. Results: A total of 13 dcCSEMS were implanted in 11 patients (2 female, 9 male, median age 47, range 33 – 71). All patients had distal biliary strictures due to chronic pancreatitis. No stent migration occurred. In all but one patient the stents were removed. One patient refused stent extraction and was lost to follow up. Stent occlusion occurred twice leading to cholangitis in both cases. The duration of stent treatment was 170 days (range 61 – 254). After extraction only one patient had early recurrent stricture and received the same stent again. Three stents showed minimal tissue granulation at the papilla. One stent presented ingrowth at the proximal end and was removed after implantation of a second fully covered stent. Mechanical examination revealed significantly lower radial expansion force of the new stent as compared to the cylindrical stent. Conclusions: The new stent design has a low rate of migration. Biomechanical properties may explain this effect. PMID:26793789

    Understanding the relationships between spirituality and health has become increasingly important in health research, including nursing research. Very little of the research thus far has focused on spirituality, religion, and pain even though spiritual views have been intertwined with beliefs about pain and suffering throughout history. Spiritual views can have a substantial impact on patients' understanding of pain and decisions about pain management. The author reviews the research literature on spirituality and pain from a historical perspective. The analysis is concerned with how spirituality and religion have been used to construct a meaning of pain that shapes appraisal, coping, and pain management. The clinical implications include respectful communication with patients about spirituality and pain, inclusion of spirituality in education and support programs, integration of spiritual preferences in pain management where feasible and appropriate, consultation with pastoral care teams, and reflection by nurses about spirituality in their own lives. A discussion of research implications is included.

  11. Pain, objectivity and history: understanding pain stigma.

    PubMed

    Goldberg, Daniel S

    2017-02-21

    The primary claim of this paper is that understanding the stigma so commonly endured by chronic pain sufferers today in the USA and the UK is unlikely without proper appreciation of the history of pain. Ameliorating such stigma is an ethical imperative, and yet most approaches eschew even an attempt to trace connections between historical attitudes, practices and beliefs towards pain and the stigmatisation so many pain sufferers currently endure. The manuscript aims to help fill this gap by framing pain in the modern era in context of two crucial intellectual schemes that waxed in the 19th and 20th centuries: mechanical objectivity and somaticism. The analysis explains these frameworks and applies them to exploration of primary sources connected to contested pain conditions such as railway spine. By properly situating the historical roots of what it means to cite the 'subjectivity' of pain as a problem, the modern roots of stigmatising attitudes and practices towards chronic pain sufferers become much clearer. The manuscript concludes by suggesting that interventions expressly intended to target the root causes of such stigma are much more likely to be successful than approaches that proceed in ignorance of the historical forces shaping and driving pain stigma in the present.

    The painful events associated with the treatment of a severe burn can, because of their long-lasting and repetitive characteristics, be one of the most excruciating experiences in clinical practice. Moreover, burn pain has been shown to be detrimental to burn patients. Although nociception and peripheral hyperalgesia are considered the major causes of burn pain, the study of more hypothetical mechanisms like central hyperalgesia and neuropathic pain may lead to a better understanding of burn pain symptoms and to new therapeutic approaches. Continuous pain and intermittent pain due to therapeutic procedures are two distinct components of burn pain. They have to be evaluated and managed separately. Although continuous pain is by far less severe than intermittent pain, the treatment is, in both cases, essentially pharmacological relying basically on opioids. Because of wide intra- and inter-individual variations, protocols will have to leave large possibilities of adaptation for each case, systematic pain evaluation being mandatory to achieve the best risk/benefit ratio. Surprisingly, the dose of medication decreases only slowly with time, a burn often remaining painful for long periods after healing. Non pharmacological treatments are often useful and sometimes indispensable adjuncts; but their rationale and their feasibility depends entirely on previous optimal pharmacological control of burn pain. Several recent studies show that burn pain management is inadequate in most burn centres.

    Osteoporosis is a common complication of chronic liver disease, from cholestatic disorders to autoimmune, alcoholic, and posthepatitic cirrhosis. Osteoporosis appears more striking in patients with primary biliary cirrhosis (PBC) because the disease usually affects elderly women, who are naturally prone to osteoporosis. Our aims were (1) to compare the prevalence of osteoporosis (T-score <-2.5 SD) between PBC patients and a group of age-and sex-matched controls consisting of healthy subjects from the general population; and (2) to identify the main risk factors for the development of bone loss. Thirty-three women with PBC (mean age, 47.3 +/- 10.4 years) and 66 healthy subjects were enrolled in the study. Bone mineral density (BMD) was assessed at the lumbar spine by dual-photon X-ray absorptiometry. Bone metabolism was evaluated by measuring serum calcium corrected for serum albumin, 25-hydroxyvitamin D (25-OH vit D), parathyroid hormone, and osteocalcin. Vertebral fractures were analyzed using vertebral fracture assessment (VFA). The mean T-score was lower in the PBC group compared to healthy controls, with a significant statistical difference (-2.39 +/- 0.93 and -1.47 +/- 0.99 in lumbar spine and total hip, respectively, in the PBC group versus -0.99 +/- 0.51 and -0.56 +/- 1.14 in healthy controls (P < 0.001). The prevalence of osteoporosis was 51.5% in the PBC group versus 22.7% in healthy controls with a statistically significant difference (P = 0.004). BMD of the PBC group was significantly correlated positively with body mass index (BMI) and 25-OH vit D, and negatively with menopausal status, duration of disease, and parathyroid hormone (PTH) levels. Vertebral fractures were present in 9% of the patients. We found that osteoporosis is more prevalent in women with PBC than in the general population. BMI, menopausal status, duration of the disease, and vitamin D deficiency are the main risk factors for osteoporosis in this liver disease.

    The purpose of this study was to describe the types of pain information described by older adults with chronic osteoarthritis pain. Pain descriptions were obtained from older adults’ who participated in a posttest only double blind study testing how the phrasing of healthcare practitioners’ pain questions affected the amount of communicated pain information. The 207 community dwelling older adults were randomized to respond to either the open-ended or closed-ended pain question. They viewed and orally responded to a computer displayed videotape of a practitioner asking them the respective pain question. All then viewed and responded to the general follow up question, ““What else can you tell me?” and lastly, “What else can you tell me about your pain, aches, soreness or discomfort?” Audio-taped responses were transcribed and content analyzed by trained, independent raters using 16 a priori criteria from the American Pain Society (2002) Guidelines for the Management of Pain in Osteoarthritis, Rheumatoid Arthritis, and Juvenile Chronic Arthritis. Older adults described important but limited types of information primarily about pain location, timing, and intensity. Pain treatment information was elicited after repeated questioning. Therefore, practitioners need to follow up older adults’ initial pain descriptions with pain questions that promote a more complete pain management discussion. Routine use of a multidimensional pain assessment instrument that measures information such as functional interference, current pain treatments, treatment effects, and side effects would be one way of insuring a more complete pain management discussion with older adults.

    Background/Aims In distal malignant biliary obstruction, an antireflux metal stent (ARMS) with a funnel-shaped valve is effective as a reintervention for metal stent occlusion caused by reflux. This study sought to evaluate the feasibility of this ARMS as a first-line metal stent. Methods Patients with nonresectable distal malignant biliary obstruction were identified between April and December 2014 at three Japanese tertiary centers. We retrospectively evaluated recurrent biliary obstruction and adverse events after ARMS placement. Results In total, 20 consecutive patients were included. The most common cause of biliary obstruction was pancreatic cancer (75%). Overall, recurrent biliary obstruction was observed in seven patients (35%), with a median time to recurrent biliary obstruction of 246 days (range, 11 to 246 days). Stent occlusion occurred in five patients (25%), the causes of which were sludge and food impaction in three and two patients, respectively. Stent migration occurred in two patients (10%). The rate of adverse events associated with ARMS was 25%: pancreatitis occurred in three patients, cholecystitis in one and liver abscess in one. No patients experienced non-occlusion cholangitis. Conclusions The ARMS as a first-line biliary drainage procedure was feasible. Because the ARMS did not fully prevent stent dysfunction due to reflux, further investigation is warranted.

    It is now recognized that from the newborn period onwards, children are capable of experiencing pain. This includes the premature infant. The challenge for healthcare providers is to incorporate methods of pain assessment and treatment into their daily practices. The child's understanding of pain closely follows the cognitive and behavioral model developed by Jean Piaget. Based on these developmental stages, pain assessment measures have been developed. Pharmacologic advances have accompanied this improved understanding of infant, child, and adolescent psychology. While acute pain accounts for the majority of children's experiences, recurrent/chronic pain states do occur (e.g. sickle cell related and neuropathic) and can be effectively treated.

    It has long been appreciated that the experience of pain is highly variable between individuals. Pain results from activation of sensory receptors specialized to detect actual or impending tissue damage (i.e., nociceptors). However, a direct correlation between activation of nociceptors and the sensory experience of pain is not always apparent. Even in cases in which the severity of injury appears similar, individual pain experiences may vary dramatically. Emotional state, degree of anxiety, attention and distraction, past experiences, memories, and many other factors can either enhance or diminish the pain experience. Here, we review evidence for “top-down” modulatory circuits that profoundly change the sensory experience of pain. PMID:21041960

    Since its introduction, MRCP has been improved over the years due to the introduction of several technical advances and innovations. It consists of a noninvasive method for biliary tree representation, based on heavily T2-weighted images. Conventionally, its protocol includes two-dimensional single-shot fast spin-echo images, acquired with thin sections or with multiple thick slabs. In recent years, three-dimensional T2-weighted fast-recovery fast spin-echo images have been added to the conventional protocol, increasing the possibility of biliary anatomy demonstration and leading to a significant benefit over conventional 2D imaging. A significant innovation has been reached with the introduction of hepatobiliary contrasts, represented by gadoxetic acid and gadobenate dimeglumine: they are excreted into the bile canaliculi, allowing the opacification of the biliary tree. Recently, 3D interpolated T1-weighted spoiled gradient echo images have been proposed for the evaluation of the biliary tree, obtaining images after hepatobiliary contrast agent administration. Thus, the acquisition of these excretory phases improves the diagnostic capability of conventional MRCP-based on T2 acquisitions. In this paper, technical features of contrast-enhanced magnetic resonance cholangiography are briefly discussed; main diagnostic tips of hepatobiliary phase are showed, emphasizing the benefit of enhanced cholangiography in comparison with conventional MRCP.

    Biliary atresia is an obstructive cholangiopathy of infancy that progresses to end-stage cirrhosis. Although the pathogenesis of the disease is not completely understood, previous reports link TNFα to apoptosis of the bile duct epithelium in the presence of IFNγ. Here, we investigate if TNFα signaling regulates pathogenic mechanisms of biliary atresia. First, we quantified the expression of TNFA and its receptors TNFR1 and TNFR2 in human livers and found an increased expression of the receptors at the time of diagnosis. In mechanistic experiments using a neonatal mouse model of rhesus rotavirus–induced (RRV-induced) biliary atresia, the expression of the ligand and both receptors increased 6- to 8-fold in hepatic DCs and NK lymphocytes above controls. The activation of tissue NK cells by RRV-primed DCs was independent of TNFα-TNFR signaling. Once activated, the expression of TNFα by NK cells induced lysis of 55% ± 2% of bile duct epithelial cells, which was completely prevented by blocking TNFα or TNFR2, but not TNFR1. More notably, antibody-mediated or genetic disruption of TNFα-TNFR2 signaling in vivo decreased apoptosis and epithelial injury; suppressed the infiltration of livers by T cells, DCs, and NK cells; prevented extrahepatic bile duct obstruction; and promoted long-term survival. These findings point to a key role for the TNFα/TNFR2 axis on pathogenesis of experimental biliary atresia and identify new therapeutic targets to suppress the disease phenotype. PMID:28289704

    The proliferative-crypt compartment of the intestinal epithelium is enriched in phospholipids and accumulation of phospholipids has been described in colorectal tumors. Here we hypothesize that biliary phospholipid flow could directly contribute to the proliferative power of normal and dysplastic enterocytes. We used Abcb4−/− mice which lack biliary phospholipid secretion. We first show that Abcb4−/− mice are protected against intestinal tumorigenesis. At the molecular level, the transcriptional activity of the nuclear receptor Liver Receptor Homolog-1 (Lrh1) is reduced in Abcb4−/− mice and its re-activation re-establishes a tumor burden comparable to control mice. Feeding Abcb4−/− mice a diet supplemented with phospholipids completely overcomes the intestinal tumor protective phenotype, thus corroborating the hypothesis that the absence of biliary phospholipids and not lack of Abcb4 gene per se is responsible for the protection. In turn, phospholipids cannot re-establish intestinal tumorigenesis in Abcb4−/− mice crossed with mice with intestinal specific ablation of Lrh1, a nuclear hormone receptor that is activates by phospholipids. Our data identify the key role of biliary phospholipids in sustaining intestinal mucosa proliferation and tumor progression through the activation of nuclear receptor Lrh1. PMID:27995969

    Cholangiocarcinomas (CCAs) are heterogeneous tumors arising from the biliary tract with features of cholangiocyte differentiation. CCAs are aggressive tumors with limited treatment options and poor overall survival. Only a subset of CCA patients with early stage disease can avail potentially curative treatment options. For advanced biliary tract tumors, currently there are limited effective treatment modalities. Recent advances have provided greater insight into the genomic landscape of CCAs. The fibroblast growth factor receptor (FGFR) pathway is involved in key cellular processes essential to survival and differentiation. Accordingly, aberrant FGFR signaling has significant oncogenic potential. Recent discovery of FGFR2 gene fusions in CCA has heightened interest in FGFR inhibition in advanced biliary tract cancer. These findings have served as a catalyst for ongoing clinical investigation of FGFR inhibition in CCA patients with various FGFR signaling abnormalities. Herein, we review FGFR aberrations in CCA and their prognostic implications, FGFR targeting as a viable therapeutic option in advanced biliary tract malignancies, and future directions for development of combination approaches utilizing FGFR inhibition.

    Accurate preoperative assessment of the hepatic vascular and biliary anatomy is essential to ensure safe and successful hepatic surgery. Such surgical procedures range from the more complex, like tumor resection and partial hepatectomy for living donor liver transplantation, to others performed more routinely, like laparoscopic cholecystectomy. Modern noninvasive diagnostic imaging techniques, such as multidetector computed tomography (CT) and magnetic resonance (MR) imaging performed with liver-specific contrast agents with biliary excretion, have replaced conventional angiography and endoscopic cholangiography for evaluation of the hepatic vascular and biliary anatomy. These techniques help determine the best hepatectomy plane and help identify patients in whom additional surgical steps will be required. Preoperative knowledge of hepatic vascular and biliary anatomic variants is mandatory for surgical planning and to help reduce postoperative complications. Multidetector CT and MR imaging, with the added value of image postprocessing, allow accurate identification of areas at risk for venous congestion or devascularization. This information may influence surgical planning with regard to the extent of hepatic resection or the need for vascular reconstruction.

    Malignant biliary tract obstruction (MBTO) due to either primary biliary tract cancer or metastasis to the porta hepatis is a common clinical problem. The most common metastatic tumors causing MBTO in order of frequency are gastric, colon, breast, and lung cancers. Radiographic diagnostic procedures should proceed in a cost-effective sequence from ultrasonography, computerized tomography (CT), percutaneous transhepatic cholangiography (PTHC), and endoscopic retrograde pancreatography with the goal of establishing the site of the biliary tract obstruction. The identification of the site of obstruction could be established by ultrasound 70% to 80%, CT scan 80% to 90%, PTHC 100%, and endoscopic retrograde cholangiography (ERCP) 85%. Therapeutic intervention by radiographic decompression (PTHC or endoscopic prosthesis), surgical bypass, or radiation therapy with or without chemotherapy may be selectively used based on (1) the site of obstruction; (2) the type of primary tumor; and (3) the presence of specific symptoms related to the obstruction. ("Prophylactic" biliary tract decompression to prevent ascending cholangitis is not supported by the literature in that the frequency of sepsis in the face of malignant obstruction is small (in contrast to sepsis associated with stone disease). Furthermore, PTHC with drainage as a long-term procedure is associated with a substantial frequency of sepsis and is unnecessary and possibly problematic as a preoperative procedure simply to reduce the bilirubin level. The use of radiation therapy in conjunction with chemotherapy for patients not deemed suitable for a surgical bypass because of the presence of proximal obstruction is an important alternative to PTHC.

    Treatment of biliary ileus is still controversial in respect of surgical strategy. While some surgeons have agreed enterolithotomy as a simple and safe operation, others prefer to perform enterolithotomy, cholecystectomy and repair bilio-enteric fistula at the same time. The authors examine their experience and discuss various modalities of treatment to identify the rational method of therapy in these patients.

    Purpose: To evaluate the efficacy of covered stents for the treatment of transjugular intrahepatic portosystemic shunt (TIPS) obstruction in human subjects with identified or suspected biliary fistulae. Methods: Five patients were treated for early failure of TIPS revisions. All had mid-shunt thrombus, and four of these had demonstrable biliary fistulae. Three patients also propagated thrombus into the native portal venous system and required thrombolysis. TIPS were revised in four patients using a custom-made polytetrafluoroethylene (PTFE)-covered Wallstent, and in one patient using a custom-made PTFE-covered Gianturco Z-stent. Results: All identified biliary fistulae were successfully sealed. All five patients maintained patency and function of the TIPS during follow-up ranging from 2 days to 21 months (mean 8.4 months). No patient has required additional revision. Thrombosis of the native portal venous system was treated with partial success by mechanical thrombolysis. Conclusion: Early and recurrent failure of TIPS with mid-shunt thrombosis, which may be associated with biliary fistulae, can be successfully treated using covered stents. Stent-graft revision appears to be safe, effective, and potentially durable.

    Since its introduction, MRCP has been improved over the years due to the introduction of several technical advances and innovations. It consists of a noninvasive method for biliary tree representation, based on heavily T2-weighted images. Conventionally, its protocol includes two-dimensional single-shot fast spin-echo images, acquired with thin sections or with multiple thick slabs. In recent years, three-dimensional T2-weighted fast-recovery fast spin-echo images have been added to the conventional protocol, increasing the possibility of biliary anatomy demonstration and leading to a significant benefit over conventional 2D imaging. A significant innovation has been reached with the introduction of hepatobiliary contrasts, represented by gadoxetic acid and gadobenate dimeglumine: they are excreted into the bile canaliculi, allowing the opacification of the biliary tree. Recently, 3D interpolated T1-weighted spoiled gradient echo images have been proposed for the evaluation of the biliary tree, obtaining images after hepatobiliary contrast agent administration. Thus, the acquisition of these excretory phases improves the diagnostic capability of conventional MRCP—based on T2 acquisitions. In this paper, technical features of contrast-enhanced magnetic resonance cholangiography are briefly discussed; main diagnostic tips of hepatobiliary phase are showed, emphasizing the benefit of enhanced cholangiography in comparison with conventional MRCP.

    The examination of 86 helicopter pilots has shown that their exposure to vibration leads to biliary and gallbladder damage which aggravates with longer service. As indicated by spectroscopy and gas-liquid chromatography, vibration affects colloid-osmotic properties of bile: molecules grow in size, bile acids retention becomes longer.

  11. New clues for the developing human biliary system at the porta hepatis.

    The human biliary system is formed from the hepatic diverticulum, a structure which develops from the embryonic foregut in the fourth week of gestation. The cephalic portion of the hepatic diverticulum lies within the septum transversum, and gives rise to entodermal cells which become the primitive hepatocytes. The caudal part of the hepatic diverticulum is molded by mesenchyme to form the gallbladder, cystic duct, and extrahepatic bile duct. The gallbladder is initially tubular in shape, and undergoes morphological changes to become saccular during the 11th week of gestation. The extrahepatic bile duct elongates and widens as gestation progresses, and intramural mucus glands develop. There is no solid stage during the development of the extrahepatic bile duct. The extrahepatic bile duct is a well-defined tubular structure by the 6th week of gestation, whereas the intrahepatic biliary system during this period of gestation is represented by the primitive ductal plate. The ductal plate undergoes structural changes from the 11th week of gestation, beginning at the porta hepatis and progressing through gestation to the periphery of the liver. This remodeling process shapes the ductal plate from a flat sheath of biliary epithelium surrounding the portal vein branches into a network of interconnecting tubular structures. Mesenchyme plays an important role in ductal plate remodeling. The intrahepatic biliary system is in luminal continuity with the extrahepatic bile duct throughout gestation at the porta hepatis. The major bile ducts at the porta hepatis are fully formed by the 16th week of gestation.

    Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) represent the major clinical entities of chronic cholestatic liver diseases. Both disorders are characterized by portal inflammation and slowly progress to obliterative fibrosis and eventually liver cirrhosis. Although immune-pathogenic mechanisms have been implicated in the pathogenesis of PBC and PSC, neither disorder is considered to be a classical autoimmune disease, as PSC and PBC patients do not respond to immune-suppressants. Furthermore, the decreased bile flow resulting from the immune-mediated tissue assault and the subsequent accumulation of toxic bile products in PBC and PSC not only perpetuates biliary epithelial damage, but also alters the composition of the intestinal and biliary microbiota and its mutual interactions with the host. Consistent with the close association of PSC and inflammatory bowel disease (IBD), the polyclonal hyper IgM response in PBC and (auto-)antibodies which cross-react to microbial antigens in both diseases, an expansion of individual microbes leads to shifts in the composition of the intestinal or biliary microbiota and a subsequent altered integrity of epithelial layers, promoting microbial translocation. These changes have been implicated in the pathogenesis of both devastating disorders. Thus, we will discuss here these recent findings in the context of novel and alternative therapeutic options.

    Infection of neonatal mice with some reovirus strains produces a disease similar to infantile biliary atresia, but previous attempts to correlate reovirus infection with this disease have yielded conflicting results. We used isogenic reovirus strains T3SA– and T3SA+, which differ solely in the capacity to bind sialic acid as a coreceptor, to define the role of sialic acid in reovirus encephalitis and biliary tract infection in mice. Growth in the intestine was equivalent for both strains following peroral inoculation. However, T3SA+ spread more rapidly from the intestine to distant sites and replicated to higher titers in spleen, liver, and brain. Strikingly, mice infected with T3SA+ but not T3SA– developed steatorrhea and bilirubinemia. Liver tissue from mice infected with T3SA+ demonstrated intense inflammation focused at intrahepatic bile ducts, pathology analogous to that found in biliary atresia in humans, and high levels of T3SA+ antigen in bile duct epithelial cells. T3SA+ bound 100-fold more efficiently than T3SA– to human cholangiocarcinoma cells. These observations suggest that the carbohydrate-binding specificity of a virus can dramatically alter disease in the host and highlight the need for epidemiologic studies focusing on infection by sialic acid–binding reovirus strains as a possible contributor to the pathogenesis of neonatal biliary atresia.

    The expanded indications of partial grafts in pediatric liver transplantation have reduced waiting list mortality. However, a higher morbidity is observed, including an increased rate of biliary complications (BCs). Factors such as the type of graft, the preservation methods applied, the donor characteristics, the type of biliary reconstruction, and the number of bile ducts in the liver graft influences the occurrence of these complications. Bile leaks and strictures comprise the majority of post-transplant BCs. Biliary strictures require a high grade of suspicion, and because most children have a bileo-enteric anastomosis, its diagnosis and management rely on percutaneous hepatic cholangiography and percutaneous biliary interventions (PBI). The success rates with PBI range from 70% to 90%. Surgery is reserved for patients who have failed PBI. BCs in children after liver transplantation have a prolonged treatment and are associated with a longer length of stay and higher hospital costs. However, with early diagnosis and aggressive treatment, patient and graft survival are not significantly compromised. PMID:26328028

    Objectives To describe the occurrence of pancreatic, biliary tract, and gallbladder cancers within the Alaska Native (AN) population. Study design Population-based analysis utilizing a tumor registry and comparative population data. Methods Pancreaticobiliary cancers rates for AN people during 1973–2007 were determined from the Surveillance, Epidemiology, and End Results (SEER) AN Tumor Registry. Cancer incidence rates were age-adjusted to the World Standard Million and compared over 2 time periods with US white and black rates. Results During 1973–2007, 213 AN people developed pancreatic cancer, 73 gallbladder cancer and 61 biliary tract cancer. Pancreatic cancer occurs at similar rates in AN men and women, but data for 1993–2007 indicate that the rates among AN men may be increasing. The incidence rate in AN women (9.5/100,000) was statistically higher than in US white women (5.8/100,000). The incidence for biliary tract cancer in AN men and gallbladder cancer in AN men and women is statistically higher than that for US whites and blacks. Conclusions Pancreaticobiliary cancers, particularly biliary tract and gallbladder cancers, in both AN men and women and pancreatic cancer in women occur at an increased rate in AN people. Risk factors relating to the elevated rate are discussed. Certain factors are potentially modifiable, such as the use of tobacco and obesity. PMID:22456038

    The authors point out the therapeutic properties of sulphate-bicarbonate mineral waters. After summarizing the general mechanism of action of mineral waters, the main indications of such waters in thermal treatment are examined including: biliary sand, biliary dyskinesia, functional dyspepsia, irritable colon, chronic primitive constipation. The dysfunctions of biliary and digestive tracts are growing, mainly in the affluent world, because of the increase for stress, dietary habits, modern life style. Now they affect from 2,4% of general population to 7% of men and 20% of women, according to different studies. Mineral waters can improve symptoms and care some physiopathological underlying mechanisms. Authors stress the efficacy of sulphate-bicarbonate mineral waters in the therapy of biliary dyskinesias, namely gallbladder hypokinesia and Oddi's sphincter spasm, caused by their content in SO4 = anion and Mg++ cation and related effects on paracrine-endocrine gastrointestinal system. In addition, they report the effects of sulphate-bicarbonate mineral waters in the lithogenic bile (sand bile), because of their diluting and washing activity. Among the sulphate-bicarbonate mineral waters, the Authors outline the well-documented therapeutic activity of Acqua Santa and Fucoli of Chianciano Terme. Acqua Santa has stimulating effect on cholecystis's motility, as proved by controlled clinical trials. Finally, the therapeutic use of sulphate-bicarbonate mineral water is discussed in functional dyspepsia, chronic primitive constipation and irritable bowel syndrome.

    OBJECTIVE To examine bile acid composition of gallbladder contents in dogs with gallbladder mucocele and biliary sludge. ANIMALS 18 dogs with gallbladder mucocele (GBM group), 8 dogs with immobile biliary sludge (i-BS group), 17 dogs with mobile biliary sludge (m-BS group), and 14 healthy dogs (control group). PROCEDURES Samples of gallbladder contents were obtained by use of percutaneous ultrasound-guided cholecystocentesis or during cholecystectomy or necropsy. Concentrations of 15 bile acids were determined by use of highperformance liquid chromatography, and a bile acid compositional ratio was calculated for each group. RESULTS Concentrations of most bile acids in the GBM group were significantly lower than those in the control and m-BS groups. Compositional ratio of taurodeoxycholic acid, which is 1 of 3 major bile acids in dogs, was significantly lower in the GBM and i-BS groups, compared with ratios for the control and m-BS groups. The compositional ratio of taurocholic acid was significantly higher and that of taurochenodeoxycholic acid significantly lower in the i-BS group than in the control group. CONCLUSIONS AND CLINICAL RELEVANCE In this study, concentrations and fractions of bile acids in gallbladder contents were significantly different in dogs with gallbladder mucocele or immobile biliary sludge, compared with results for healthy control dogs. Studies are needed to determine whether changes in bile acid composition are primary or secondary events of gallbladder abnormalities.

    A whole-organ regeneration approach, using a decellularised xenogeneic liver as a scaffold for the construction of a transplantable liver was recently reported. Deriving suitable scaffolds was the first step towards clinical application; however, effective recellularisation remains to be achieved. This report presents a strategy for the improvement of the recellularisation process, using novel cell-seeding technique and cell source. We evaluated recellularised liver grafts repopulated through the portal vein or the biliary duct with mice adult hepatocytes or E14.5 foetal hepatocytes. More than 80% of the cells seeded through the biliary tree entered the parenchyma beyond the ductule-lining matrix barrier and distributed throughout the liver lobule. In contrast, about 20% of the cells seeded through the portal tree entered the parenchyma. The gene expression levels of foetal hepatocyte albumin, glucose 6-phosphatase, transferrin, cytokeratin 19, and gamma-glutamyl transpeptidase were increased in three-dimensional cultures in the native liver-derived scaffolds, and the activation of liver detoxification enzymes and formation of biliary duct-like structures were supported. The metabolic functions of liver grafts recellularised with different cell types were similar. These results suggest that biliary tree cell-seeding approach is promising, and that liver progenitor cells represent a good cell source candidate. PMID:27767181

    The functional interrelationship between biliary cholesterol secretion, sinusoidal lipoprotein cholesterol secretion and bile salt synthesis was studied in the rat. Diosgenin, fructose, and colestipol in the diet were used to, respectively, influence biliary cholesterol output, VLDL production and bile salt synthesis. In the acute bile fistula rat, biliary cholesterol output was 700% increased by diosgenin and 50% decreased by fructose. In the rats fed both diosgenin and fructose, biliary cholesterol secretion was increased only by approximately 200%, whereas biliary bile salts and phospholipid outputs were unchanged. In the isolated perfused liver, VLDL-cholesterol output was 50% reduced by diosgenin alone, but was unchanged following feeding of diosgenin plus fructose. However, the livers of rats fed diosgenin plus fructose exhibited a 700% increase in VLDL-triglyceride production and a 200% increase in VLDL-cholesterol output. A significant reciprocal relationship between VLDL-cholesterol secretion and the coupling ratio of cholesterol to bile salts in bile was observed. Colestipol added to the diet maintained both sinusoidal and biliary cholesterol outputs within the normal range. In the chronic bile fistula rat, colestipol increased bile salt synthesis by 100% while diosgenin and fructose diets had no effect. Similarly, the addition of fructose to the colestipol diet did not decrease bile salt synthesis. These data suggest a reciprocal relationship between biliary cholesterol secretion and hepatic secretion of cholesterol as VLDL particles. The free cholesterol pool used for bile salt synthesis seems functionally unrelated to the pool from which VLDL-cholesterol and biliary cholesterol originate. These findings support the idea that metabolic compartmentalization of hepatic cholesterol is a major determinant of the quantity of cholesterol available for recruitment by the bile salt-dependent biliary cholesterol secretory mechanism.
