    To evaluate predictive factors for false-negative diagnosis of percutaneous forceps biopsies in patients suspected of having a malignant biliary obstruction Two hundred seventy one consecutive patients with obstructive jaundice underwent percutaneous forceps biopsy. In each patient, three to five specimens (mean, 3.5 specimens) were collected from the lesion. The final diagnosis for each patient was confirmed with pathologic findings at surgery, additional histocytologic data, or clinical and radiologic follow-up. Univariate and multivariate logistic regression analysis was used to identify risk factors associated with false-negative diagnosis. One hundred ninety four of 271 biopsies resulted in correct diagnoses of malignancy, while 20 biopsy diagnoses were proved to be true-negative. There were 57 false-negative diagnoses and no false-positive diagnoses. The diagnostic performance of transluminal forceps biopsy in malignant biliary obstructions was as follows: sensitivity, 77.2%; specificity, 100%; and accuracy, 78.9%; positive predictive value, 100%, negative predictive value; 25.9%. Periampullary segment of common bile duct, intrahepatic bile duct and metastatic disease were the significant risk factors of false-negative diagnosis. Percutaneous forceps biopsy provides relatively high accuracy in the diagnosis of malignant biliary obstructions. The predictive factors of false-negative biopsy were determined to be biopsy site and origin of primary tumour. (orig.)

    The optimal management of patients with suspected biliary obstruction remains unclear, and includes the possible performance of magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP). To complete a cost analysis based on a medical effectiveness randomized trial comparing an ERCP-first approach with an MRCP-first approach in patients with suspected bile duct obstruction. The management strategies were based on a medical effectiveness trial of 257 patients over a 12-month follow-up period. Direct and indirect costs were included, adopting a societal perspective. The cost values are expressed in 2012 Canadian dollars. Total per-patient direct costs were Can$3547 for ERCP-first patients and Can$4013 for MRCP-first patients. Corresponding indirect costs were Can$732 and Can$694, respectively. Causes for differences in direct costs included a more frequent second procedure and a greater mean number of hospital days over the year in patients of the MRCP-first group. In contrast, it is the ERCP-first patients whose indirect costs were greater, principally due to more time away from activities of daily living. Choosing an ERCP-first strategy rather than an MRCP-first strategy saved on average Can$428 per patient over the 12-month follow-up duration; however, there existed a large amount of overlap when varying total cost estimates across a sensitivity analysis range based on observed resources utilization. This cost analysis suggests only a small difference in total costs, favoring the ERCP-first group, and is principally attributable to procedures and hospitalizations with little impact from indirect cost measurements.

    The preferred initial investigation with either magnetic resonance (MRCP) or endoscopic retrograde cholangiopancreatography (ERCP) in patients with suspected biliary obstruction remains controversial in many clinical settings. To assess the effectiveness of an initial MRCP vs. ERCP in the work-up of patients at moderate likelihood of a suspected biliary obstruction. Patients with an unconfirmed benign biliary obstruction, based on laboratory and ultrasound findings, were randomised to an ERCP-first or MRCP-first strategy, stratified by level of obstruction. The primary outcome was the occurrence of a disease or procedure-related bilio-pancreatic adverse events within the next 12 months. Secondary outcomes were the number of subsequent bilio-pancreatic procedures, duration of hospitalisation, days away from activities of daily living (ADL), quality of life (SF-36) and mortality. We randomised 126 patients to ERCP-first and 131 to MRCP-first (age 54 ± 18 years, 62% female, 39% post-cholecystectomy). In follow-up, 18/126 (14.3%) ERCP-first and 25/131 (19.1%) MRCP-first patients experienced a procedure- or disease-related complication (P = 0.30) (disease-related in 13 and 18 patients, and procedure-related in 5 and 7 patients respectively). A cause of biliary obstruction was found in 39.7% vs. 49.6% of patients (P = 0.11). Sixty-six (50%) patients in the MRCP-first group ended up avoiding an ERCP in follow-up. ERCP-first and MRCP-first patients were away from usual activities for 3.4 ± 7.7 days and 2.0 ± 4.8 days respectively (P < 0.001). A strategy of MRCP-first decreased the need for subsequent MRCPs, but not complications. Further study is required to define factors influencing the eventual use of MRCP vs. ERCP in appropriately selected patients (ClinicalTrial.gov: NCT01424657). © 2013 John Wiley & Sons Ltd.

    Our purpose was to report the use of percutaneous catheter drainage as a therapeutic option in the management of three patients with biliary-pleural fistulas without biliary obstructions. In the proper clinical setting, the CT findings of liver dome laceration or abscess, diaphragm disruption, and pleural effusion should suggest biliary-pleural fistula. Percutaneous catheter management can be curative or serve a temporizing function before surgery.

    A 63-year-old man with extrahepatic portal vein thrombosis presented with biliary obstruction and hemobilia after a liver biopsy. Balloon sweep of the common bile duct removed clotted blood, and cholangiogram showed a common bile duct narrowing, treated with biliary stenting. A percutaneous biliary catheter was later required for recurrent biliary obstruction and hemobilia, and repeat cholangiogram confirmed portal biliopathy-a large peri-biliary varix was compressing the common bile duct, causing biliary obstruction and intermittent portal hypertensive hemobilia. A transjugular intrahepatic portosystemic shunt was inserted, followed by embolization of the peri-biliary varix. Delayed diagnosis of portal biliopathy may lead to significant patient morbidity.

    Metallic stents have been widely used relieve biliary obstructions as an alternative to plastic endoprostheses. In this study, we evaluate the efficacy of the metallic stents in the management of malignant biliary obstruction. If cancerous tissue was present in the bile duct, the stents embedded in the tumor and caliber of the bile duct was smaller than that of the stents. Metallic stents are indicated in case with less tumor in the bile duct. If bulky tumor exists in the bile duct, adequate combination therapy to reduce the volume of the tumor should be required. In the case of inefficient therapy, plastic endoprosthesis or covered stents should be chosen for long-term patency. (author)

    Full Text Available The biliary ileum is an infrequent complication of cholelithiasis, that is manifested as an intestinal obstruction, is more prevalent in aged people. The clinical square of the biliary ileum is diffuse and the Triad of Rigler is observed in less than 30% of the patient one. The surgical treatment goes from enterotomía and litotricia to the colecistectomía with treatment of the water-pipe. The case of a female, 86-year-old patient is presented that after a week of symptoms and of medical treatment it was detected the presence of a mechanical intestinal obstruction for which the patient underwent emergency surgery. As the cause of occlusion it was found a thick gallstone in a jejunal loop.

    Biliary obstruction is usually caused by choledocholithiasis. However, in some circumstances, alternative or concurring unusual ethiologies such as portal hypertensive biliopathy (PHB) must be considered. We present the case of a 36-year-old female complaining of jaundice and pruritus. Liver function tests were compatible with biliary obstruction and the ultrasound scan of the abdomen showed dilatation of the intrahepatic biliary ducts, a dilated common bile duct (CBD) and biliary calculi. The computed tomography of the abdomen revealed a portal cavernoma encasing the CBD. Portal cavernoma, the hallmark of extrahepatic portal venous obstruction, can cause PHB. When symptomatic, chronic cholestasis is present if a dominant stricture exists whereas biliary pain and acute cholangitis occur when choledocholithiasis prevails. Management must be individualized and usually includes endoscopic therapy to address choledocholithiasis and shunt surgery for definitive treatment.

    Objectives: The aimed of this study was to investigate the value of intra-biliary contrast-enhanced ultrasound (IB-CEUS) for evaluating biliary obstruction during percutaneous transhepatic biliary drainage (PTBD). Materials and methods: 80 patients with obstructive jaundice who underwent IB-CEUS during PTBD were enrolled. The diluted ultrasound contrast agent was injected via the drainage catheter to perform IB-CEUS. Both conventional ultrasound and IB-CEUS were used to detect the tips of the drainage catheters and to compare the detection rates of the tips. The obstructive level and degree of biliary tract were evaluated by IB-CEUS. Fluoroscopic cholangiography (FC) and computer tomography cholangiography (CTC) were taken as standard reference for comparison. Results: Conventional ultrasound displayed only 43 tips (43/80, 53.8%) of the drainage catheters within the bile ducts while IB-CEUS identified all 80 tips (80/80, 100%) of the drainage catheters including 4 of them out of the bile duct (P < 0.001). IB-CEUS made correct diagnosis in 44 patients with intrahepatic and 36 patients with extrahepatic biliary obstructions. IB-CEUS accurately demonstrated complete obstruction in 56 patients and incomplete obstruction in 21 patients. There were 3 patients with incomplete obstruction misdiagnosed to be complete obstruction by IB-CEUS. The diagnostic accuracy of biliary obstruction degree was 96.3% (77/80). Conclusion: IB-CEUS could improve the visualization of the drainage catheters and evaluate the biliary obstructive level and degree during PTBD. IB-CEUS may be the potential substitute to FC in the PTBD procedure.

    As recent advances in chemotherapy and surgical treatment have improved outcomes in patients with biliary cancers, the search for an optimal strategy for relief of their obstructive jaundice has become even more important. Without satisfactory relief of biliary obstruction, many patients would be ineligible for treatment. We review all prospective randomized trials and recent retrospective non-randomized studies for evidence that would support such a strategy. For distal malignant biliary obstruction, an optimal strategy would be insertion of metallic stents either endoscopically or percutaneously. Evidence shows that a metallic stent inserted percutaneously has better outcomes than plastic stents inserted endoscopically. For malignant hilar obstruction, percutaneous biliary drainage with or without metallic stents is preferred.

    There is limited experience of percutaneous biliary interventions in children although they are safe and effective procedures. To evaluate the efficacy and safety of percutaneous management of tumoral biliary obstruction in children. Percutaneous biliary interventions were performed in eight children (six boys, two girls) with a mean age of 10.5 years (range 4-17 years). The interventions included percutaneous biliary drainage (five patients), percutaneous biliary drainage and placement of a self-expanding metallic stent (two patients), and percutaneous cholecystostomy (one patient). All patients had signs of obstructive jaundice and two had cholangitis. All procedures were successful. No procedure-related mortality was observed. Bilirubin levels returned to normal in four of the eight patients. Findings of cholangitis resolved in the two affected patients after the procedure and antibiotic treatment. Two patients underwent surgery after percutaneous biliary drainage procedures. A self-expanding metallic stent was placed in two patients with malignancy and the stents remained patent until death. Percutaneous biliary interventions can be performed safely for the management of tumoral biliary obstruction in children. (orig.)

    Background Patients with obstructive jaundice have various pathophysiological changes that affect the liver, kidney, heart, and the immune system. There is considerable controversy as to whether temporary relief of biliary obstruction prior to major definitive surgery (pre-operative biliary drainage) is of any benefit to the patient. Objectives To assess the benefits and harms of pre-operative biliary drainage versus no pre-operative biliary drainage (direct surgery) in patients with obstructive jaundice (irrespective of a benign or malignant cause). Search methods We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, Cochrane Central Register of Controlled Clinical Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until February 2012. Selection criteria We included all randomised clinical trials comparing biliary drainage followed by surgery versus direct surgery, performed for obstructive jaundice, irrespective of the sample size, language, and publication status. Data collection and analysis Two authors independently assessed trials for inclusion and extracted data. We calculated the risk ratio (RR), rate ratio (RaR), or mean difference (MD) with 95% confidence intervals (CI) based on the available patient analyses. We assessed the risk of bias (systematic overestimation of benefit or systematic underestimation of harm) with components of the Cochrane risk of bias tool. We assessed the risk of play of chance (random errors) with trial sequential analysis. Main results We included six trials with 520 patients comparing pre-operative biliary drainage (265 patients) versus no pre-operative biliary drainage (255 patients). Four trials used percutaneous transhepatic biliary drainage and two trials used endoscopic sphincterotomy and stenting as the method of pre-operative biliary drainage. The risk of bias was high in all trials. The proportion of patients with malignant obstruction varied between 60

    To evaluate the long-term patency of the Hanaro spiral stent (Solco Intermed, Seoul, Korea) when used as a palliative in patients with inoperable malignant biliary obstruction. Between April 1996 and July 1998, 39 patients with malignant biliary obstruction underwent percutaneous placement of 48 Hanaro spiral stents. The causes of obstruction were bile duct carcinoma (n=18), pancreatic carcinoma (n=8), metastatic lymphadenopathy (n=5), gallbladder carcinoma (n=5), hepatocellular carcinoma (n=1) and other tumors (n=2). Using the kaplan-Meier method, patient survival and stet patency rates were estimated with regard to level of obstruction. As regards stent insertion, there was no technical failure. Overall 25- and 50-week survival rates for the entire patient group were 50 % and 11 %, respectively, while overall stent patency rates at 25 and 50 weeks were 42 % and 11 %, respectively. Twenty-five-week stent patency rates in patients with common bile duct (CBD) and hilar obstruction were 51 % and 18 %, respectively. The stent patency rates in the CBD obstruction group was significantly higher than that in the hilar obstruction group (p<0.05). In patients with CBD obstruction, the clinical efficacy of Hanaro spiral stent was superior to that in patients with hilar obstruction. However, Hanaro spiral stents showed a lower patency rate with regard to patient survival, and further investigation is required.

    To evaluate the feasibility, safety and the effectiveness of the complex assembly of open cell nitinol stents for biliary hilar malignancy. During the 10 month period between January and October 2007, 26 consecutive patients with malignant biliary hilar obstruction underwent percutaneous insertion of open cell design nitinol stents. Four types of stent placement methods were used according to the patients' ductal anatomy of the hilum. We evaluated the technical feasibility of stent placement, complications, patient survival, and the duration of stent patency. Bilobar biliary stent placement was conducted in 26 patients with malignant biliary obstruction-T (n = 9), Y (n 7), crisscross (n = 6) and multiple intersecting types (n = 4). Primary technical success was obtained in 24 of 26 (93%) patients. The crushing of the 1st stent during insertion of the 2nd stent occurred in two cases. Major complications occurred in 2 of 26 patients (7.7%). One case of active bleeding from hepatic segmental artery and one case of sepsis after procedure occurred. Clinical success was achieved in 21 of 24 (87.5%) patients, who were followed for a mean of 141.5 days (range 25-354 days). The mean primary stent patency period was 191.8 days and the mean patient survival period was 299 days. Applying an open cell stent in the biliary system is feasible, and can be effective, especially in multiple intersecting stent insertions in the hepatic hilum.

    A double lumen catheter was developed as an applicator for the remote afterloading system (RALS) of {sup 60}Co for the intracavitary irradiation of an obstructed common bile duct due to gallbladder cancer in 1 case and by cholangiocarcinoma in 7 cases. This was followed by the biliary endoprosthesis with expandable metallic stents to maintain patency. The mean survival period after treatment was not long (14 weeks). However, removal of the external drainage tube was possible in 7 of the 8 cases, and none of the 8 cases showed dislodgement or deformity of the stent, or obstruction of the bile duct in the stent-inserted area. This combination effectively provided palliation, and has considerable potential for malignant biliary obstruction. (author).

    Full Text Available Ceftriaxone (CTRX is known to cause reversible biliary stones/sludge, which is called biliary pseudolithiasis. We report two rare cases of biliary obstruction by pseudolithiasis shortly after completing CTRX treatment. Stones and sludge, which had not been detected before CTRX administration, appeared in the gallbladder and common bile duct and led to biliary obstruction and acute cholangitis. The obstructions were successfully treated with endoscopic retrograde biliary drainage and endoscopic sphincterotomy. CTRX-induced biliary pseudolithiasis has been reported mainly in children and adolescents but is also seen in adults with similar incidence rate. Although CTRX-induced biliary pseudolithiasis is usually asymptomatic and disappears spontaneously after discontinuing the drug, some patients develop biliary obstruction. Endoscopic managements should be considered in such cases.

    Ceftriaxone, a third-generation cephalosporin, has been associated with the development of sludge or stones in the gallbladders of some patients treated with this medication. Such precipitates, which are usually reversible upon discontinuation of the drug, sometimes cause symptoms, have simulated acute cholecystitis, and have even led to cholecystectomy in some cases. We report the first known instance of biliary obstruction and secondary pancreatitis in association with reversible ceftriaxone-induced pseudolithiasis.

    Currently, diagnosis of obstructive jaundice has become easier with CT and USEG, and percutaneous transhepatic cholangialdrainage (PTCD) for obstructive jaundice has also become much safer using USEG control. We have performed PTCD in 277 cases, from December 1976 to May 1989 at Saitama Cancer Center with specially designed thin needle. And using a PTCD fistula, we have been attempted radiotherapy for 7 cases of the bile duct cancer using Remoto After Loading System (RALS), and hyperthermia for 5 cases of bile duct cancer using antenna of microwaves. From autopsy cases, we evaluated treated lesion pathologically, and we obtained the following results. Dosage of biliary RALS need up to 50 Gy at the point of 1 cm from {sup 60}Co sourse. Biliary hyperthermia using microwave seem to be unsuccessful, and further improvement to the antenna of microwave were necessary. Furthermore, we have attempted biliary endoprosthesis 27 cases, for better quality of life to the patients with malignant obstructive jaundice. These methods seem to be effective in prolonging patient's lives, comparing of cases in which PTCD of an external fistula has been performed. (author).

    Full Text Available Percutaneous management of unresectable malignant biliary obstruction remains challenging. Biliary radiofrequency ablation (RFA using the Habib EndoHBP catheter is a new palliation therapy for malignant biliary obstruction. We report our initial experience of RFA for the management of malignant biliary obstruction. A 58-year-old male was diagnosed with gallbladder cancer. Intraductal bipolar RFA was delivered at power of 10 W for 120 s, followed by stent placement. The patient had immediate stricture improvements after RFA. No severe adverse event occurred. Percutaneous RFA seems to be safe and feasible for the treatment of malignant biliary obstruction. Further studies are warranted.

    Full Text Available ObjectiveTo investigate the safety and feasibility of percutaneous intraductal radiofrequency ablation (palliative therapy in the treatment of malignant obstructive jaundice. MethodsThis study included 20 patients with unresectable malignant obstructive jaundice, who were treated in the First Affiliated Hospital of Zhengzhou University from January 2013 to March 2014. Nine of them (test group underwent percutaneous intraductal radiofrequency ablation plus metallic biliary stent placement. The other 11 similar cases (control group underwent metallic biliary stent placement alone after successful percutaneous transhepatic cholangiography. Operative complications and remission of jaundice were observed, and the stent patency after at 3 and 6 months after operation was evaluated and compared between the two groups. ResultsAll patients were followed completely by outpatient or telephone. The stent patency rate at 3 months after operation was 9/9 in the test group and 8/11 in the control group (χ2=2.888, P=0.218, and the stent patency rates at 6 months were 7/8 and 3/11, respectively (χ2=6.739, P=0.02. During follow-up, one case in the test group died of gastrointestinal bleeding at 113 d after operation; one case in the control group died of liver failure at 57 d after operation and one case died of disseminated intravascular coagulation at 142 d. ConclusionPercutaneous intraductal radiofrequency ablation is safe and feasible in the treatment of malignant biliary obstruction, and the preliminary efficacy in prolonging the patency of self-expanding metallic stent is satisfactory. However, this therapy needs to be further verified via large-sample randomized controlled studies.

    A 59-year-old man with a known central hepatocellular carcinoma (HCC) underwent a trans-arterial-chemo-embolization (TACE) and a post-TACE percutaneous radiofrequency ablation (PRFA). Two months after the PRFA, the patient presented jaundice and an abdominal computed tomography was obtained. An arterial enhancing mass adjacent to the ablated necrotic lesion with a continuously coexisting mass inside the right hepatic duct, suggestive of a HCC recurrence with a direct extension to the biliary tract was found. Finally a biliary tumor obstruction has been developed and a percutaneous transhepatic biliary drainage was performed. This case of biliary obstruction caused by directly invaded recurred HCC after PRFA will be reported because of its rare occurrence.

    Biliary obstruction in chronic calcific pancreatitis (CCP) is often caused by inflammatory or fibrotic strictures of the bile duct, carcinoma of head of pancreas or less commonly by compression from pseudocysts. Pancreatic calculi causing ampullary obstruction and leading to obstructive jaundice is extremely rare. The medical records of all patients with CCP or biliary obstruction who underwent endoscopic retrograde cholangiopancreatography (ERCP) over 4 years between 2010-2014 at Kasturba Medical College, Manipal were analyzed. Five patients of CCP with impacted pancreatic calculi at the ampulla demonstrated during ERCP were identified. All 5 presented with biliary obstruction and were incidentally detected to have CCP when evaluated for the same; 3 patients had features of cholangitis. All the patients were managed successfully by endoscopic papillotomy and extraction of pancreatic calculi from the ampulla with resolution of biliary obstruction. Pancreatic calculus causing ampullary obstruction, though very rare, should be considered as a possibility in patients with CCP complicated by biliary obstruction. Endoscopic therapy is affective in the resolution of biliary obstruction in such patients.

    Here, we present a case of malignant biliary tract obstruction with severe obesity, which was successfully treated by endoscopic ultrasonography-guided biliary drainage (EUS-BD). A female patient in her sixties who had been undergoing chemotherapy for unresectable pancreatic head cancer was admitted to our institution for obstructive jaundice. She had diabetes mellitus, and her body mass index was 35.1 kg/m2. Initially, endoscopic retrograde cholangiopancreatography (ERCP) was performed, but bile duct cannulation was unsuccessful. Percutaneous transhepatic biliary drainage (PTBD) from the left hepatic biliary tree also failed. Although a second PTBD attempt from the right hepatic lobe was accomplished, biliary tract bleeding followed, and the catheter was dislodged. Consequently, EUS-BD (choledochoduodenostomy), followed by direct metallic stent placement, was performed as a third drainage method. Her postprocedural course was uneventful. Following discharge, she spent the rest of her life at home without recurrent jaundice or readmission. In cases of severe obesity, we consider EUS-BD, rather than PTBD, as the second drainage method of choice for distal malignant biliary obstruction when ERCP fails. PMID:27698669

    For four years up to December 1987, 190 patients (median age 73 years) with proximal malignant biliary obstruction were treated by endoscopic endoprosthesis insertion. Altogether 101 had cholangiocarcinoma, 21 gall bladder carcinoma, 20 local spread of pancreatic carcinoma, and 48 metastatic malignancy. Fifty eight patients had type I, 54 type II, and 78 type III proximal biliary strictures (Bismuth classification). All patients were either unfit or unsuitable for an attempt at curative surgical resection. A single endoprosthesis was placed initially, with a further stent being placed only if relief of cholestasis was insufficient or sepsis developed in undrained segments. The combined percutaneous-endoscopic technique was used to place the endoprosthesis when appropriate, after failed endoscopic endoprosthesis insertion or for second endoprosthesis placement. Full follow up was available in 97%.Thirteen patients were still alive at the time of review and all but one had been treated within the past six months. Initial endoprosthesis insertion succeeded technically at the first attempt in 127 patients, at the second in 30, and at a combined procedure in a further 13 (cumulative total success rate 89% - type I: 93%; type II: 94%; and type III: 84%). There was adequate biliary drainage after single endoprosthesis insertion in 152 of the 170 successful placements, giving an overall successful drainage rate of 80%. Three patients had a second stent placed by combined procedure because of insufficient drainage, giving an overall successful drainage rate of 82% (155 of 190). The final overall drainage success rates were type I: 91%; type II: 83%; and type III: 73%. The early complication rates were type I: 7%; type II: 14%; and type III: 31%. The principle early complication was clinical cholangitis, which occurred in 13 patients (7%) and required second stent placement in five. The 30 day mortality was 22% overall (type I: 14%; type II: 15%; and type III: 32%) but the

    The purpose of this study was to evaluate the patency, procedure related complications and effectiveness of Wallstent application to the malignant biliary obstruction as a palliative treatment. We retrospectively reviewed the clinical results, duration of survival, patency rate and complication of the Wallstent application on 33 patients who had had obstructive jaundice by the malignant lesion in recent 3 years. One or two step procedures were mainly taken with 10 mm diameter Wallstents. Grouping according to place the stent at the hilum or not, and grouping according to place the stent through the ampulla or not were done to evaluate the difference of the patency and survival rate between the groups. Biliary endoprosthesis with Wallstent were successfully placed in all patients without difficulty. Procedure related short-term complication rate was about 18.1% (n = 6/33). Complications were fever (n = 4), cholecystitis (n = 1) and sepsis (n = 1). Long-term complications were mainly obstruction (n = 9/31) of the Wallstent during the follow-up period. Also cholecystitis occurred in one patient 3 months later. Mean survival duration was 139.72 (46-237) days among those who expired. Mean patency duration of stents was 139.67 (26-310) days. Survival rates were 93.5% at the second month, 68.8% at the third month, 61.2% at the 4th month, 53.5% at the 5th month, 49.1% at the 7th month and 35.7% at the 9th month. Patency rates were 93.7% at the second month, 84.2% at the 4th month, 66.9% at the 5th month, 59.5% at the 7th month and 39.6% at the 10th month. The application was repeated in the 6 patients with stent occlusion. Significant statistical difference could not be found between the groups according to placing the stent at the hilum and according to placing the stent through the ampulla. Patency rates were higher than survival rates in the follow-up period. Wallstent application provides good palliation with little discomfort and few complications in the patients with

    Biliary decompression in cases of central tumorous biliary obstruction requires surgical or internal/external catheter bypass techniques. The development of a 14-F Y-shaped-polyurethane endoprosthesis stent provides the possibility to drain the left and right biliary system simultaneously. The endoprosthesis is placed by a combination of external transhepatic and endoscopic approach. The tip of the singular choledochal stent segment is placed within the choledochus or duodenum.

    Ultrasonography (US) cannot demonstrate all the etiologies of biliary tract dilatation in patients with jaundice. Thus, we evaluated the etiologic yield of endosonography (EUS) for suspected obstructive jaundice when no definite pathology was found on US. Additionally, we sought to identify the predictors of the most common etiologies. We performed a retrospective review of 123 consecutive patients who had undergone EUS for suspected obstructive jaundice when no definite pathology was identified on US. The most common diagnoses included no pathological obstruction (n = 43), pancreatobiliary malignancy (n = 41), and choledocholithiasis (n = 28). Pancreatobiliary malignancy was associated with common bile duct (CBD) dilatation, and fever and elevated alanine aminotransferase were predictors of choledocholithiasis (p jaundice, 100% (40/40) for no pathological finding, 100% (23/23) for ampullary cancer, 100% (13/13) for pancreatic cancer, 75% (3/4) for CBD cancer, and 92.9% (26/28) for choledocholithiasis, respectively. Besides the two patients with focal chronic pancreatitis misdiagnosed as with pancreatic cancer, EUS missed the lesions in one CBD cancer patient and two patients with choledocholithiasis. The overall accuracy of EUS in ascertaining pancreatobiliary malignancy and choledocholithiasis was comparable (97.6%, 40/41 vs. 92.9%, 26/28; p > 0.05). Marked CBD dilatation (≥12 mm) should remind us of the high risk of malignancy, and the presence of CBD dilatation and fever is suggestive of choledocholithiasis. Negative EUS findings cannot assure any pathological obstruction in patients with clinically suspected obstructive jaundice. Copyright © 2013. Published by Elsevier B.V.

    To evaluate the usefulness of the percutaneous transluminal biopsy using 7-F forceps for diagnosing malignant biliary obstruction. One hundred and seven consecutive patients with obstructive jaundice underwent transluminal forceps biopsy. The lesions involved the common bile duct (n = 33), common hepatic duct (n = 13), hilum (n = 17), right or left intrahepatic bile duct (n = 32), multiple sites (extra and intrahepatic ducts, n = 7), or anastomotic sites (n = 5). In each patient, an average of three specimens was taken with 7F biopsy forceps through a transhepatic biliary drainage tract. The final diagnosis was confirmed with pathologic findings, or a clinical and radiologic follow up. The final diagnoses showed malignancies in 75 patients and benign biliary obstructions in 32 patients. Pathologic classifications of malignancies established by forceps biopsy included 67 adenocarcinomas, 1 adenosquamous cell carcinoma, and 1 hepatocelluar carcinoma. There were 6 false-negative diagnoses. The diagnostic performance of transluminal forceps biopsy in malignant biliary obstruction had a sensitivity of 92%, specificity of 100%, positive predictive value of 100%, a negative predictive value of 84.2%, and an accuracy of 94.2%. Percutaneous transluminal forceps biopsy is a safe procedure that is easy to perform through a transhepatic biliary drainage tract. It is a highly accurate technique for diagnosing malignant biliary obstructions.

    Magnetic compression anastomosis (MCA) is a revolutionary, minimally invasive method of performing choledochoenterostomy or choledochocholedochostomy without using surgical techniques in patients with biliary stricture or obstruction. Herein, we describe a case series of MCA for severe biliary stricture or obstruction, which could not be treated with conventional therapies. Two patients with biliary obstruction were treated using MCA for choledochocholedochostomy and choledochoenterostomy at Tokyo Medical University Hospital and Tokyo Medical University Hachioji Medical Center. Endoscopically, a samarium-cobalt (Sm-Co) rare-earth magnet was placed at the superior site of obstruction through the percutaneous transhepatic biliary drainage route and another Sm-Co magnet was placed at the inferior site of obstruction. A comprehensive computer-aided literature search for MCA was performed up to September 2009 by using MEDLINE and EMBASE. MCA techniques enabled complete anastomosis in both cases without procedure-related complications. The MCA technique is a revolutionary method of performing choledochocholedochostomy and choledochoenterostomy interventionally in patients with biliary obstruction, for whom the conventional endoscopic procedure is not available, or in candidates who are deemed unsuitable for surgery.

    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.

    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. 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.

    PurposeVarious methods have been used to sample biliary strictures, including percutaneous fine-needle aspiration biopsy, intraluminal biliary washings, and cytological analysis of drained bile. However, none of these methods has proven to be particularly sensitive in the diagnosis of biliary tract malignancy. We report improved diagnostic accuracy using a modified technique for percutaneous transluminal biopsy in patients with this disease.Materials and MethodsFifty-two patients with obstructive jaundice due to a biliary stricture underwent transluminal forceps biopsy with a modified “cross and push” technique with the use of a flexible biopsy forceps kit commonly used for cardiac biopsies. The modification entailed crossing the stricture with a 0.038-in. wire leading all the way down into the duodenum. A standard or long sheath was subsequently advanced up to the stricture over the wire. A Cook 5.2-Fr biopsy forceps was introduced alongside the wire and the cup was opened upon exiting the sheath. With the biopsy forceps open, within the stricture the sheath was used to push and advance the biopsy cup into the stricture before the cup was closed and the sample obtained. The data were analysed retrospectively.ResultsWe report the outcomes of this modified technique used on 52 consecutive patients with obstructive jaundice secondary to a biliary stricture. The sensitivity and accuracy were 93.3 and 94.2 %, respectively. There was one procedure-related late complication.ConclusionWe propose that the modified “cross and push” technique is a feasible, safe, and more accurate option over the standard technique for sampling strictures of the biliary tree.

    Autoimmune pancreatitis (AIP) responds dramatically to corticosteroids treatment. We reviewed our experience to determine the safety and effectiveness of treating obstructive jaundice in definitive AIP with corticosteroids alone without biliary stenting. From our AIP database, we retrospectively identified type 1 AIP subjects whose jaundice was treated with corticosteroids alone without biliary stenting. Their medical records were reviewed and clinical data were evaluated to determine the outcomes. Fifteen AIP subjects (87% male, mean age 68.4 years) were treated with corticosteroids at initial presentation (n = 8), first (n = 5) or subsequent (n = 2) relapse. Mean values (upper limit of normal, ULN) of liver tests prior to corticosteroids were aspartate aminotransferase (AST) 203.5u/l (4 × ULN), alanine aminotransferase (ALT) 325.8u/l (6 × ULN), alkaline phosphatase (ALP) 567.4u/l (5 × ULN), and total bilirubin (TB) 5.9 mg/dl (5.9 × ULN). At first follow-up (mean 4 days) the decrease was 54.9% for AST, 51.6% for ALT, 33% for ALP and 47.2% for TB (all p  1.5 × ULN, 1/15 had ALP > 1.5 × ULN, 1/15 had TB > 1.5 × ULN. No patient required biliary stent placement, or developed cholangitis or other infectious complications during steroid treatment. Under the supervision of an experienced pancreatologist and with close monitoring of patients, obstructive jaundice secondary to definitive AIP can be safely and effectively managed with corticosteroids alone, without the need for biliary stenting.

  4. Role of glucuronidation for hepatic detoxification and urinary elimination of toxic bile acids during biliary obstruction.

    Directory of Open Access Journals (Sweden)

    Martin Perreault

    Full Text Available Biliary obstruction, a severe cholestatic condition, results in a huge accumulation of toxic bile acids (BA in the liver. Glucuronidation, a conjugation reaction, is thought to protect the liver by both reducing hepatic BA toxicity and increasing their urinary elimination. The present study evaluates the contribution of each process in the overall BA detoxification by glucuronidation. Glucuronide (G, glycine, taurine conjugates, and unconjugated BAs were quantified in pre- and post-biliary stenting urine samples from 12 patients with biliary obstruction, using liquid chromatography-tandem mass spectrometry (LC-MS/MS. The same LC-MS/MS procedure was used to quantify intra- and extracellular BA-G in Hepatoma HepG2 cells. Bile acid-induced toxicity in HepG2 cells was evaluated using MTS reduction, caspase-3 and flow cytometry assays. When compared to post-treatment samples, pre-stenting urines were enriched in glucuronide-, taurine- and glycine-conjugated BAs. Biliary stenting increased the relative BA-G abundance in the urinary BA pool, and reduced the proportion of taurine- and glycine-conjugates. Lithocholic, deoxycholic and chenodeoxycholic acids were the most cytotoxic and pro-apoptotic/necrotic BAs for HepG2 cells. Other species, such as the cholic, hyocholic and hyodeoxycholic acids were nontoxic. All BA-G assayed were less toxic and displayed lower pro-apoptotic/necrotic effects than their unconjugated precursors, even if they were able to penetrate into HepG2 cells. Under severe cholestatic conditions, urinary excretion favors the elimination of amidated BAs, while glucuronidation allows the conversion of cytotoxic BAs into nontoxic derivatives.

The factors prognostic the early mortality after surgical derivation are: hemoglobin 10 mg/dL and serum albumin ictericia, pain and prurito. 61 cases of distal obstruction and 36 with proximal obstruction. Twenty deaths (25.9%) happened within the 30 later days to the treatment. The bilirubin > 14 mg/dL and the proximal location were like predicting of early mortality. The obstruction biliary more frequent is located in choledocho distal and is of pancreatic origin. The main factors associated to early mortality are: the bilirubin > of 14 mg/dL and the proximal location reason why is important the suitable selection of patient candidates to endoscopic derivation. The survival is better in the distal obstruction.

Technical and clinical success with metallic stents is obtained in over 90% and 80% of cases, respectively. There are self-expandable metallic stents designed to increase permeability. The aim of this study was to describe the results obtained with totally covered self-expandable and uncovered self-expandable metallic stents in the palliative treatment of malignant biliary obstruction. Patients and methods: Sixty eight patients with malignant obstructive jaundice secondary to pancreatobiliary or metastatic disease not amenable to surgery were retrospectively included. Two groups were created: group A (covered self-expandable metallic stents (n = 22 and group B (uncovered self-expandable metallic stents (n = 46. Results: Serum total bilirubin, direct bilirubin, alkaline phosphatase and gamma glutamyl transferase levels decreased in both groups and no statistically significant difference was detected (p = 0.800, p = 0.190, p = 0.743, p = 0.521. Migration was greater with covered stents but it was not statistically significant either (p = 0.101. Obstruction was greater in the group with uncovered stents but it was not statistically significant either (p = 0.476. Conclusion: There are no differences when using covered self-expandable stents or uncovered self-expandable stents in terms of technical and clinical success or complications in the palliative treatment of malignant obstructive jaundice.

     Recent literature suggests that chemo(radio)therapy might reduce the patency of plastic stents in patients with malignant biliary obstruction. Whether this might also be valid for other types of stents is unknown. The aim of this study was to determine the influence of chemo(radio)therapy on the patency of fully-covered self-expandable metal stents (FCSEMSs) and plastic stents.  We retrospectively reviewed the electronic medical records of patients with distal malignant biliary obstruction who underwent biliary stent placement between April 2001 and July 2015. Primary outcome was duration of stent patency. Secondary outcome was stent patency at 3 and 6 months. We used Kaplan-Meier survival analyses to compare stent patency rates between patients who received chemo(radio)therapy and patients who did not.  A total of 291 biliary stents (151 metal and 140 plastic) were identified. The median cumulative stent patency of FCSEMSs did not differ between patients receiving chemo(radio)therapy (n = 51) and those (n = 100) who did not ( P  = 0.70, log-rank test). The estimated cumulative stent patency of plastic stents was also comparable in 99 patients without and 41 patients with chemo(radio)therapy ( P  = 0.73, log-rank test). At 3 and 6 months, FCSEMS patency rates were 87 % and 83 % in patients without chemo(radio)therapy and 96 % and 83 % in patients with therapy, respectively. Plastic patency rates were 69 % and 55 % in patients without and 85 % and 39 % in patients with therapy, respectively. After 1 year, 78 % of the FCSEMSs were still patent in patients without chemo(radio)therapy and 69 % of the FCSEMSs were still patent in patients with therapy.  Our data indicate that chemo(radio)therapy does not reduce the patency of biliary fully-covered metal and plastic stents.

    To review the usefulness of endoscopic biliary stenting for obstructive jaundice caused by hepatocellular carcinoma and identify problems that may need to be addressed. The study population consisted of 36 patients with obstructive jaundice caused by hepatocellular carcinoma (HCC) who underwent endoscopic biliary stenting (EBS) as the initial drainage procedure at our hospital. The EBS technical success rate and drainage success rate were assessed. Drainage was considered effective when the serum total bilirubin level decreased by 50% or more following the procedure compared to the pre-drainage value. Survival time after the procedure and patient background characteristics were assessed comparatively between the successful drainage group (group A) and the non-successful drainage group (group B). The EBS stent patency duration in the successful drainage group (group A) was also assessed. The technical success rate was 100% for both the initial endoscopic nasobiliary drainage and EBS in all patients. Single stenting was placed in 21 patients and multiple stenting in the remaining 15 patients. The drainage successful rate was 75% and the median interval to successful drainage was 40 d (2-295 d). The median survival time was 150 d in group A and 22 d in group B, with the difference between the two groups being statistically significant (P jaundice caused by HCC, as it appears to contribute to prolongation of survival time.

    PurposeThe major complication occurring with biliary stents is stent occlusion, frequently seen because of tumour in-growth, epithelial hyperplasia, and sludge deposits, resulting in recurrent jaundice and cholangitis. We report a prospective study with the results of first in man percutaneous intraductal radiofrequency (RF) ablation to clear the blocked metal stents in patients with malignant biliary obstruction using a novel bipolar RF catheter.MethodsNine patients with malignant biliary obstruction and blocked metal stents were included. These patients underwent intraductal biliary RF ablation through the blocked metal stent following external biliary decompression with an internal–external biliary drainage.ResultsAll nine patients had their stent patency restored successfully without the use of secondary stents. Following this intervention, there was no 30-day mortality, haemorrhage, bile duct perforation, bile leak, or pancreatitis. Of the nine patients, six are alive and three patients are dead with a median follow-up of 122 (range 50–488) days and a median stent patency of 102.5 (range 50–321) days. Six patients had their stent patent at the time of last follow-up or death. Three patients with stent blockage at 321, 290, and 65 days postprocedure underwent percutaneous transhepatic drain insertion and repeat ablation.ConclusionsIn this selective group of patients, it appears that this new approach is safe and feasible. Efficacy remains to be proven in future, randomized, prospective studies.

    Fifty consecutive matched patients with benign or malignant biliary tract obstruction were compared to determine the efficacy of preoperative percutaneous biliary drainage (PBD). Twenty-five patients underwent PBD for an average of nine days before operation; 25 patients underwent percutaneous transhepatic cholangiography ( PTHC ) followed immediately by operation. Serum bilirubin levels before PTHC were 16.5 +/- 7.6 mg/dL and 14.9 +/- 7.6 mg/dL in PBD and non-PBD groups, respectively. Serum bilirubin levels decreased to 6.5 +/- 6.2 mg/dL preoperatively in patients having PBD. One week after operation, bilirubin levels were 4.2 +/- 4.3 mg/dL and 9.0 +/- 5.2 mg/dL in the PBD and non-PBD groups, respectively. Major morbidity (sepsis, abscess, renal failure, or bleeding) occurred in two patients (8%) having PBD and in 13 patients (52%) without PBD. One patient (4%) with PBD, and five patients (20%) without PBD, died. The mean hospital stay was shorter for the PBD group. Preoperative PBD reduces operative mortality and morbidity and results in a more rapid resolution of hyperbilirubinemia during the postoperative period.

    To study the feasibility and therapeutic effect of the application of (125)I seeds combined with biliary stent implantation on the treatment of malignant obstructive jaundice. Fifty patients with malignant obstructive jaundice treated from September 2010 to February 2013 in Yantai Yuhuangding Hospital were included in this study. Among them, 24 patients received biliary stent implantation combined with (125)I seeds intraluminal brachytherapy as experimental group, and 26 were treated by biliary stent implantation as control group.The total bilirubin, direct bilirubin and tumor markers (CA-199, CA-242, CEA) before and after surgery, the biliary stent patency status was assessed, and the survival time was evaluated. The 24 patients in experimental group were implanted with 30 (125)I seeds successfully in a total of 450 seeds. Jaundice was improved greatly in both groups. The CA-199 and CA-242 after treatment in the experimental group were significantly decreased than that before treatment (P=0.003 and P=0.004). CEA was also decreased, but showed no statistical significance (P>0.05). There were no significant improvement comparing the CA-199, CA-242 and CEA before and 2 months after surgery in the control group (P>0.05). The rate of biliary stent patency was 83.3% (20/24) in the experimental group and 57.7% (15/26) in the control group (P=0.048). The mean biliary stent patency time in the experimental group was 9.84 months (range 1-15.5 months). The mean biliary stent patency time in the control group was 5.57 months (range 0.8-9 months). There was a significant difference between the two groups (P=0.018). The median survival time was 10.2 months in the experimental group and 5.4 months in the control group (Pjaundice, therefore, is a safe and effective treatment in this malignancy.

    Aim: To study the feasibility and curative effect of(125)I seeds articles combined with biliary stent implantation in the treatment of malignant obstructive jaundice. Patients and Methods: Fifty patients with malignant obstructive jaundice were included. Twenty-four were treated by biliary stent implantation combined with intraluminal brachytherapy by (125)I seeds articles as the experimental group, while the remaining 26 were treated by biliary stent implantation only as the control group. The goal of this study was to evaluate total bilirubin, direct bilirubin and tumor markers (cancer antigen (CA)-199, CA-242 and carcinoembryonic antigen (CEA)), as well as biliary stent patency status and survival time before and after surgery. Results: Jaundice improved greatly in both groups. The decreases of CA-199 and CA-242 had statistical significance (p=0.003 and p=0.004) in the experimental group. The ratio of biliary stent patency was 83.3% (20/24) in the experimental group and 57.7% (15/26) in the control group (p=0.048). The biliary stent patency time in the experimental group was 1~15.5 (mean=9.84) months. The biliary stent patency time in the control group was 0.8~9 (mean=5.57) months, which was statistically significant (p=0.018).

    To evaluate the feasibility of CT fluoroscopy (CTF)-guided percutaneous transhepatic biliary drainage (PTBD) in emergency patients with acute obstructive cholangitis. The study included 28 patients admitted to the emergency center due to obstructive jaundice and found to require urgent biliary drainage, as well as judged to have a suitable peripheral bile duct for a CTF-guided puncture (at least 4 mm in width). Prior to the CTF-guided puncture, a CT scan was performed to evaluate bile duct dilatation and the underlying causes of biliary obstruction. If the patient was judged to be a suitable candidate, a CTF-guided PTBD was performed in the same CT unit without additional fluoroscopic guidance. Technical feasibility of the procedure was investigated with the evaluation of overall success rate and causes of failure. A hepatic puncture was attempted at the left lobe in 23 patients and right lobe in five patients. The procedure was successful in 24 of 28 patients (86%) Successful biliary puncture was achieved on the first attempt in 16 patients, the second attempt in five patients, and the third attempt in three patients. The causes of failure included guide wire twisting in one patient, biliary puncture failure in two patients, and poor visualization of the guide wire in one patient. There were no significant procedure-related complication. The CTF-guided PTBD is technically feasible and highly successful in patients judged to have a suitable indication. Moreover, although the procedure is unfamiliar and inconvenient to interventionalists, it has economical advantages in that it saves time and manpower. We believe this method can be used in the emergency patients requiring urgent biliary drainage as an alternative for the fluoroscopy-guided PTBD.

    In this experimental study, we investigated the role of ozone therapy in hepatic fibrosis caused by biliary obstruction. In this study, 21 male Sprague-Dawley rats were divided equally into three groups. In the control group, only laparotomy was performed and intraperitoneal cavity is washed with 1 mL of saline. In the sham group (SG), common bile duct is binded with laparotomy and no treatment is given afterward. In the experimental group (EG) after the binding of common bile duct with laparotomy, 1 mg/kg dose and 50 mg/mL concentration of ozone were applied rectally for 21 days. Hepatic tissue sample and intracardiac blood samples were collected from all animals at postoperative 21st day with relaparatomy. When we compared the experiment to SG, we detected a decrease in aspartate aminotransferase, alkaline phosphate (ALP), total bilirubin, and direct bilirubin levels in the EG, however, only the decrease in total bilirubin levels were statistically significant (p = 0.025). Histopathological examination of livers of rats in the EG showed lower level of hepatic fibrosis and inflammation. In the SG, incomplete cirrhosis was detected in 57.1% of the rats, whereas in the EG, no cirrhosis was detected. Immunohistochemically, periportal inflammation was 100% in the SG, whereas it was seen (3/7) 42.9% in the EG. A significant decrease in positive α-smooth muscle actin reaction was observed in ozone-treated group compared with SG. We suggest that ozone can decrease the hepatic destruction levels in experimental model of biliary obstruction. Georg Thieme Verlag KG Stuttgart · New York.

    We wanted to determine the technical and clinical efficacy of placing a self-expandable PTFE-covered nitinol stent for the management of inoperable malignant biliary obstruction. Thirty six patients with inoperable malignant biliary obstructions were treated by placement of self-expandable PTFE-covered nitinol stents (S and G Biotech Corporation, Seongnam, Korea). Clinical evaluation was done with assessment of the serum bilirubin and alkaline phosphatase levels, which were measured before and after stent placement within 1 week, at 1 month and at 3 months. The patient survival rate and stent patency rate were calculated with performing Kaplan-Meier survival analysis. Successful stent placement was achieved in all the patients without procedure-related complication. Pancreatitis as an early complication occurred in two cases. The serum bilirubin and alkaline phosphatase levels were significantly decreased after the procedure. During the follow-up, recurrent obstructive jaundice occurred in six cases; stent migration occurred in four cases and tumor overgrowth occurred in two cases. The survival rates were 97%, 80%, 67% and 59% at 1, 3, 6 and 9 months, respectively. The stent patency rates were 96%, 92%, 86% and 86% at 1, 3, 6 and 9 months, respectively. Self-expandable PTFE-covered nitinol stent placement seems to be technically feasible and effective for the palliative treatment of malignant biliary obstruction.

    The abdomen, in particular the ileocecal region, appendix and colon, is the most common primary site for Burkitt non Hodgkin's lymphoma (NHL). Involvement of the bile duct is rare. The authors describe a patient with abdominal NHL in which jaundice due to bile duct obstruction was the first clinical sign. Case report: a 3 year old white boy presented with one month of progressive jaundice, clay-colored stools, tea colored urine and increase of abdominal volume. Physical examination showed jaundice 3+/4+ and pale mucosa. The abdomen was moderately distended and timpanous and the liver was enlarged. Laboratory examinations confirmed cholestasis with total bilirubin of 8.2 mg/dl (direct bilirubin of 7.8 mg/dl), and microcytic and hypochromic anemia. Ultrasonography (US) and abdominal CT showed two solid tumors in hepatic hilar topography, and dilated intrahepatic biliary tree. The Doppler US showed hepatic artery and portal vein dislocation by the nodules. Comment: although jaundice occurs frequently as a late manifestation of NHL, it is rarely seen as the presenting sign. When jaundice is the first clinical sign and image studies show hepatic hilar tumor and bile duct obstruction, NHL should be considered in the differential diagnosis. (author)

    Obstructive jaundice due to advance malignancy is a fatal problem. It most commonly occurs at the distal common bile duct or at the hilum of liver. Magnetic Resonance Cholangio Pancreatography (MRCP) and Computed Tomography (CT) are most useful in identifying the underlying cause as well as localize the position of the stricture. For those patients with unresectable disease, progressive jaundice constitutes an immediate threat to their survival, in addition to significant loss to their quality of life secondary to pruritus, malaise and cholangitis. Effective and lasting decompression of the biliary tree is a priority and consists of positioning of a biliary endoprosthesis (stent). To observe the improvement of liver function, quality of life and survival after successful insertion of endoprosthesis (stenting) in malignant biliary obstruction, a study was performed in the department of surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from September 2013 to August 2014, in 50 patients with clinically visible jaundice and unresectable disease. There were significant (p<0.001) reductions in the levels of serum bilirubin, serum alkaline phosphatase, serum SGPT and Prothrombin time from the time of admission to 2 weeks and 3 weeks after stenting. Physical and functional quality of life was greatly improved 2-4 weeks after stenting, where emotional quality remained the same throughout the study period. Successful palliation by stenting of malignant biliary obstruction is a priority to achieve improvements in liver function, quality of life and prolong survival. Endoscopic stent placement appears to be safe, well tolerated and can be offered without delay as a primary treatment option for all patients with unresectable malignant biliary lesion.

    Obstructive jaundice has been reported to influence liver elasticity, independent of liver fibrosis. The aim of our prospective study was to evaluate the changes in liver elasticity, before and after biliary drainage, in patients with obstructive jaundice, and to evaluate the correlation between elasticity measures and serum markers of liver fibrosis. This is a prospective cohort study of 20 patients with obstructive jaundice. Liver elasticity was assessed by Transient Elastography (TE) and Virtual Touch™ Quantification (VTQ). Serum total bilirubin (T-Bil) level was measured before biliary drainage (Day 0), with measures repeated at 2 days (Day 2) and 7 days (Day 7) after biliary drainage. Serum levels of the following markers of liver fibrosis were also obtained on Day 0 and Day 7: hyaluronic acid (HA), procollagen-III-peptide (P-III-P). T-Bil, TE, and VTQ for the left (VTQ-L) and right (VTQ-R) lobes of the liver were all elevated before biliary drainage, with respective levels, measured at Day 0, of 11.9 ± 1.5 mg/dl, 12.1 ± 0.9 kPa, 2.23 ± 0.10 m/s, and 1.85 ± 0.10 m/s. All values decreased on Day 7 after drainage: T-Bil, 4.7 ± 1.0 mg/dl (P elasticity measures correlated with serum levels of T-Bil, P-III-P, and HA (r = 0.35-0.67, P elasticity, measured by TE and VTQ, after biliary drainage. Measures of liver elasticity correlated to levels of T-Bil and serum markers of liver fibrosis. (UMIN ID: UMIN00001284313).

    In 69 patients with extrahepatic biliary obstruction a specially designed teflon tube, the endoprosthesis, was inserted across the ductal stenosis either by percutaneous or by endoscopic route to reduce jaundice. After gaining experience our success rate of stent placement was more than 90%. Compared with catheter drainage the endoprosthesis worked faster and more efficiently, while in palliative treatment the quality of life of the patient improved and secondary cholangitis was prevented. The rate of significant long-term stent obstruction can be tolerated in view of the expected life span of four months as an average in our material.

    To compare the Y type (side-by-side) and T type (stent-in-stent) bilateral biliary metal stenting in malignant hilar obstruction in terms of treatment outcomes, including post-stenting serum bilirubin level and stent patency. 41 consecutive patients with advanced hilar malignancies who underwent percutaneous placement of bilateral metallic stents - Y (n = 23) and T types (n = 18) - were retrospectively reviewed. We evaluated stent patency after the procedure by cholangiogram and abdominal CT. Pre- and post-stenting serum bilirubin level (total, direct bilirubin) at 1 week and at 1 month were compared. Student t-test and Kaplan-Meier method were used in the statistical analysis. After comparing the median stent patency according to both types, they did not differ significantly (Y: 38 days, T: 61 days; p 0.141). There was a more decrease in the total and direct bilirubin of the T type compared to the Y type after 1 week (p = 0.013, 0.025). However, no significant difference existed between the decreasing bilirubin rates of both types after 1 month (p = 0.923, 0.742). In patients with malignant hilar obstruction, both Y and T type bilateral metallic biliary stents are effective methods. Stent patency and bilirubin decrease rates were not significantly different.

    Full Text Available Background and Aims. For distal malignant biliary obstruction in cases with short life expectancy, occlusion of plastic stents (PSs does not usually occur before death, and the application of such a procedure is considered adequate from the viewpoint of cost-effectiveness. Methods and Setting. A new commercially available DLS with side holes, a conventional DLS, and, uncovered self-expanding metal stents (SEMSs were retrospectively evaluated in patients with jaundice due to unresectable distal malignant biliary obstruction. Results. A total of 64 patients received endoscopic biliary stenting (23 patients with the new DLS, 24 patients with conventional DLS, and 17 patients with uncovered SEMS from December 2002 to August 2009. Median patency time was found to be 198 days for the new DLS group and 99 days for the conventional DLS group, revealing a significant difference between devices. There was, however, no significant difference in median patency time between the new DLS and the uncovered SEMS (198 days versus 344 days. Conclusion. The new DLS is efficient and safe and may be considered the first choice for unresectable distal malignant obstruction in cases with short life expectancy.

    This paper gives an overview of experience and success of percutaneous transhepatic interventions in malignant biliary obstruction. Even after exhaustion of surgical and endoscopic therapy options, the percutaneously inserted stents provide effective palliation. The palliative treatment of malignant jaundice using a stent is an established procedure in clinical practice, particularly whenever the endoscopic, transpapillary approach is not possible due to high obstructions or previous surgery. The technical success rate is very high (about 95-100%), and the complication rate is about 10-30%. Since the patency rate of stents is higher than that of plastic endoprostheses, their primary use is justified despite higher costs, provided the patients are adequately selected. (orig.) [German] Vorgelegt wird eine Uebersicht ueber den gegenwaertigen Stellenwert radiologischer Interventionen bei malignen Gallenwegstenosen, die nur bei 10-20% der Patienten heilbar sind. Wenn ein endoskopisch transpapillaerer Zugang nicht moeglich ist, z. B. bei hohen Obstruktionen oder nach frueheren Eingriffen, ermoeglichen die perkutane transhepatische Punktion und Implantation von Metallendoprothesen eine gute Palliation. Die perkutane Gallengangdrainage und Stentplatzierung sind fuer den erfahrenen, interventionell taetigen Radiologen wenig kompliziert und mit einer Erfolgsrate von 95-100% dem endoskopischen Vorgehen deutlich ueberlegen. Morbiditaet und Mortalitaet der endoskopischen Verfahren waren in aelteren Arbeiten noch geringer als die der perkutanen Methoden. Aktuellen Studien zufolge sind beide Verfahren gleichwertig, wahrscheinlich aufgrund technischer Verbesserungen der perkutanen Interventionen. Die technische Erfolgsrate bei der Stentapplikation liegt ueber 95%. Mittels perkutaner transhepatischer biliaerer Drainageneinlage (PTCD) eingelegte Metallstents bleiben haeufiger und laenger offen als Plastikstents. Bei entsprechender Lebenserwartung des Patienten ist ihr Einsatz daher

    This study was designed to investigate retrospectively the feasibility of transjugular insertion of biliary stent (TIBS) for the treatment of distal malignant obstructive jaundice complicated by coagulopathy. Between April 2005 and May 2010, six patients with distal malignant obstructive jaundice associated with coagulopathy that was unable to be corrected underwent TIBS at our institution for the palliation of jaundice. Patients' medical record and imaging results were reviewed to obtain information about demographics, procedure details, complications, and clinical outcomes. The intrahepatic biliary tract was successfully accessed in all six patients via transjugular approach. The procedure was technically successfully in five of six patients, with a bare-metal stent implanted after traversing the biliary strictures. One procedure failed, because the guidewire could not traverse the biliary occlusion. One week after TIBS, the mean serum bilirubin in the five successful cases had decreased from 313 {mu}mol/L (range 203.4-369.3) to 146.2 {mu}mol/L (range 95.8-223.3) and had further decreased to 103.6 {mu}mol/L (range 29.5-240.9) at 1 month after the procedure. No bleeding, sepsis, or other major complications were observed after the procedure. The mean survival of these five patients was 4.5 months (range 1.9-5.8). On imaging follow-up, there was no evidence of stent stenosis or migration, with 100 % primary patency. When the risks of hemorrhage from percutaneous transhepatic cholangiodrainage are high, TIBS may be an effective alternative for the treatment of distal malignant obstructive jaundice.

    PurposeTo evaluate the technical feasibility and clinical efficacy of placement of a newly designed Y-shaped branched covered stent for palliative treatment of malignant hilar biliary obstruction.MethodsFrom June 2011 to September 2014, 34 consecutive patients with malignant hilar biliary obstruction underwent percutaneous placement of a Y-shaped branched covered stent for palliative treatment. Technical and clinical success, complications, cumulative patient survival, and stent patency were evaluated.ResultsStent placement was technically successful in all patients. All patients showed adequate biliary drainage on the follow-up cholangiogram. Mean serum bilirubin level (10.9 mg/dl) decreased significantly 1 week (5.7 mg/dl) and 1 month (2.6 mg/dl) after stent placement (p < 0.01). Complications associated with the procedure included hemobilia (n = 3) and biloma (n = 1). During the mean follow-up period of 225 (range 12–820) days, nine patients (26.5 %) developed stent occlusion caused by tumor overgrowth (n = 8) and sludge (n = 1). Two of them underwent coaxial placement of a second stent with good results. The median survival time was 281 days and median primary stent patency was 337 days. There were no significant differences in the patient survival and stent patency rates in relation to age, sex, or Bismuth type.ConclusionPercutaneous placement of the Y-shaped branched covered stent seems to be technically feasible and clinically effective for palliative treatment of malignant hilar biliary obstruction.

    Full Text Available Background and Study Aims. Endoscopic placement of self-expanding metal stents (SEMSs is indicated for palliation of inoperable malignant biliary obstruction. A fully covered biliary SEMS (WallFlex Biliary RX Boston Scientific, Natick, USA was assessed for palliation of extrahepatic malignant biliary obstruction. Patients and Methods. 58 patients were included in this prospective, multicenter series conducted under an FDA-approved IDE. Main outcome measurements included (1 absence of stent occlusion within six months or until death, whichever occurred first and (2 technical success, need for reintervention, bilirubin levels, stent patency, time to stent occlusion, and adverse events. Results. Technical success was achieved in 98% (57/58, with demonstrated acute removability in two patients. Adequate clinical palliation until completion of followup was achievedin 98% (54/55 of evaluable patients, with 1 reintervention due to stent obstruction after 142 days. Mean total bilirubin decreased from 8.9 mg/dL to 1.2 mg/dL at 1 month. Device-related adverse events were limited and included 2 cases of cholecystitis. One stent migrated following radiation therapy. Conclusions. The WallFlex Biliary fully covered stent yielded technically successful placement with uncomplicated acute removal where required, appropriate reduction in bilirubin levels, and low rates of stent migration and occlusion. This SEMS allows successful palliation of malignant extrahepatic biliary obstruction.

    To investigate the outcomes of percutaneous unilateral metallic stent placement in patients with a malignant obstruction of the biliary hila and a contralateral portal vein steno-occlusion. Sixty patients with a malignant hilar obstruction and unilobar portal vein steno-occlusion caused by tumor invasion or preoperative portal vein embolization were enrolled in this retrospective study from October 2010 to October 2013. All patients were treated with percutaneous placement of a biliary metallic stent, including expanded polytetrafluoroethylene (ePTFE)-covered stents in 27 patients and uncovered stents in 33 patients. A total of 70 stents were successfully placed in 60 patients. Procedural-related minor complications, including self-limiting hemobilia (n = 2) and cholangitis (n = 4) occurred in six (10%) patients. Acute cholecystitis occurred in two patients. Successful internal drainage was achieved in 54 (90%) of the 60 patients. According to a Kaplan-Meier analysis, median survival time was 210 days (95% confidence interval [CI], 135-284 days), and median stent patency time was 133 days (95% CI, 94-171 days). No significant difference in stent patency was observed between covered and uncovered stents (p = 0.646). Stent dysfunction occurred in 16 (29.6%) of 54 patients after a mean of 159 days (range, 65-321 days). Unilateral placement of ePTFE-covered and uncovered stents in the hepatic lobe with a patent portal vein is a safe and effective method for palliative treatment of patients with a contralateral portal vein steno-occlusion caused by an advanced hilar malignancy or portal vein embolization. No significant difference in stent patency was detected between covered and uncovered metallic stents.

    Endoscopic ultrasound-guided biliary drainage (EUS-BD) has emerged as an alternative to traditional radiologic and surgical drainage procedures after failed endoscopic retrograde cholangiopancreatography (ERCP). However, prospective multicenter data are lacking. The aims of this study were to prospectively assess the short- and long-term efficacy and safety of EUS-BD in patients with malignant distal biliary obstruction. Consecutive patients at 12 tertiary centers (5 US, 5 European, 1 Asian, 1 South American) with malignant distal biliary obstruction and failed ERCP underwent EUS-BD. Technical success was defined as successful stent placement in the desired position. Clinical success was defined as a reduction in bilirubin by 50 % at 2 weeks or to below 3 mg/dL at 4 weeks. Adverse events were prospectively tracked and graded according to the American Society for Gastrointestinal Endoscopy (ASGE) lexicon's severity grading system. Overall survival and duration of stent patency were calculated using Kaplan-Meier analysis. A total of 96 patients (mean age 66 years, female 45 %, pancreatic cancer 55 %) underwent EUS-BD. Stent placement (technical success) was achieved in 92 (95.8 %) patients (metallic stent 84, plastic stent 8). Mean procedure time was 40 minutes. Clinical success was achieved in 86 (89.5 %) patients. A total of 10 (10.5 %) adverse events occurred: pneumoperitoneum (n = 2), sheared wire (n = 1), bleeding (n = 1), bile leak (n = 3), cholangitis (n = 2), and unintentional perforation (n = 1); 4 graded as mild, 4 moderate, 1 severe, and 1 fatal (due to perforation). A total of 38 (44 %) patients died of disease progression during the study period. The median patient survival was 167 days (95 %CI 112 - 221) days. The 6-month stent patency rate was 95 % (95 %CI 94.94 - 95.06 %) and the 1-year stent patency was 86 % (95 %CI 85.74 - 86.26 %). This study on EUS-BD demonstrates excellent efficacy

    The study was conducted to find out the association of various naso-oro-pharyngeal structures with sleep macro-architecture in suspected obstructive sleep apnea subjects. Study included 51 subjects with suspected obstructive sleep apnea. Subjects with possible central apnea and those consuming any substance that can affect sleep architecture were excluded. Level I polysomnography was performed after thorough physical examination. Overnight study was scored in 30 s epochs to find out the polysomnographic variables. Surgical treatment was offered wherever indicated. Subjects with moderate to severe obstructive sleep apnea were manually titrated on CPAP with the polysomnogram. SPSS v 17.0 was used for statistical analysis. We did not find any difference in the sleep architecture between genders. Sleep Efficiency was better in subjects with dental overjet, dental attrition, high tongue base, macroglossia, lesser oral cavity volume, edematous uvula, increased submental fat, hypertrophied facial muscles and Mallampatti grade III-IV. Shorter Sleep Latency was seen in subjects with tender TMJ and Mallampatti Gr III-IV. REM latency was shorter in subjects with high tongue base, macroglossia and hypertrophied muscles of mastication. Increased REM was observed in subjects with high tongue base, edematous uvula and tender TMJ. Enlarged tonsils had reversed effect with poor sleep efficiency, increased REM latency and decreased REM. CPAP therapy (N = 20) lessened awake time, decreased N2 and increased REM. Oro-pharyngeal structures affect the sleep architecture in suspected OSA subjects. Nasal structures do not affect the sleep architecture in these subjects and enlarged tonsils have opposite effect. Sleep architecture changes on the titration night with CPAP.

    Covered nitinol alloy self-expandable metal stents (SEMSs) have been developed to overcome the shortcomings of steel SEMS in patients with malignant biliary obstruction. In a randomized, multicenter trial, we compared stent patency, patient survival, and adverse events in patients with partly covered stents made from steel or nitinol. A total of 400 patients with unresectable distal malignant biliary obstruction were randomized at endoscopic retrograde cholangiopancreatography (ERCP) to insertion of a steel or nitinol partially covered SEMS, with 200 patients in each group. The primary outcome was confirmed stent failure during 300 days of follow-up.  At 300 days, the proportion of patients with patent stents was 77 % in the steel group, compared with 89 % in the nitinol group (P = 0.01). Confirmed stent failure occurred more often in the steel SEMS group compared with the nitinol SEMS group, in 30 versus 14 patients (P = 0.02). Stent migration occurred in 13 patients in the steel group and in 3 patients in the nitinol group (P = 0.01). Median patient survival (secondary outcome) was 137 days and 120 days in the steel SEMS and nitinol SEMS groups, respectively (P = 0.59). The nitinol SEMS showed longer patency time, and the nitinol group had fewer patients with stent failure, compared with the steel SEMS group. We could not detect any differences between the two groups regarding survival time, and regarding adverse event rate.Clinical trial registration : NCT 00980889. © Georg Thieme Verlag KG Stuttgart · New York.

    Background and study aims: How enteroscopy-assisted ERCP (e-ERCP) and endoscopic ultrasound-guided biliary drainage (EUS-BD) compare in patients with surgically altered upper gastrointestinal anatomy is currently unknown. The aims of this study were to compare efficacy and safety of both techniques and study predictors of these outcomes. Patients and methods: This was an international, multicenter comparative cohort study at 10 tertiary centers. Outcomes data included technical success (biliary access with cholangiography and stent placement [when indicated]), clinical success (resolution of biliary obstruction) and adverse events (AEs) (graded according to the ASGE lexicon). Results: A total of 98 patients underwent EUS-BD (n = 49) or e-ERCP (n = 49). Technical success was achieved in 48 (98 %) patients in the EUS-BD group as compared to 32 (65.3 %) patients in the e-ERCP group (OR 12.48, P = 0.001). Clinical success was attained in 88 % of patients in EUS-BD group as compared to 59.1 % in the e-ERCP group (OR 2.83, P = 0.03). Procedural time was significantly shorter in the EUS-BD group (55 min vs 95 min, P < 0.0001). AEs occurred more commonly in the EUS-BD group (20 % vs. 4 %, P = 0.01). However, the majority (90 %) of AEs were mild/moderate. Length of stay was significantly longer in the EUS-BD group (6.6 d vs. 2.4 d, P < 0.0001). Conclusions: EUS-BD can be performed with a higher degree of clinical efficacy and shorter procedure time than e-ERCP in patients with surgically-altered upper gastrointestinal anatomy. Whether or not this approach should be first-line therapy in this patient population is highly dependent on the indication for the procedure, the patient's anatomy, and local practice and expertise.

    Proliferation of bile duct-like structures is a hepatic cellular reaction observed in most forms of human liver disease and in a variety of experimental conditions associated with liver injury. Yet the origin, means of initiation, and significance of this hyperplasia are unknown. To clarify these issues we induced bile duct proliferation in rats by ligating the common bile duct and studied (a) hepatic incorporation of [3H]thymidine by histoautoradiography, (b) hepatic morphometry, (c) biliary tree volume using [3H]taurocholate as a marker of biliary transit time, (d) immunohistochemical expression of cytokeratin no. 19, (e) the effect of indomethacin, and (f) the role of increased biliary pressure, in the absence of physiological and biochemical evidence of cholestasis, on [3H]thymidine incorporation by the bile-duct cells. The results have demonstrated that (a) the proliferating bile duct-like cells are products of the extant biliary epithelium and retain its characteristics; (b) bile duct cells divide irrespective of the size of the duct in which they are located and form a system with a lumen continuous with the preexisting one; (c) bile duct proliferation results mainly in elongation, not in circumferential enlargement or sprouting of side branches; (d) portal macrophage infiltration does not play a role in the hyperplastic reaction, and (e) increased biliary pressure is the initiating factor in bile duct cell division. Our results provide evidence that under the present conditions, ductular metaplasia of hepatocytes does not occur and there is no functioning stem cell for biliary epithelial growth segregated in any particular duct size or within the portal connective tissue.

    Identifying patients with obstructive coronary artery disease can be challenging for primary care physicians. Advances in precision medicine may help augment clinical tools and redefine the paradigm for evaluating coronary artery disease in the outpatient setting. A blood-based age/sex/gene expression score (ASGES) incorporating key features of precision medicine has shown clinical validity with a 96% negative predictive value and 89% sensitivity in estimating a symptomatic patient's current likelihood of obstructive coronary artery disease. To better characterize the clinical utility of the ASGES and measure its impact on clinician decision-making, a community-based registry was established. The prospective PRESET Registry (NCT01677156) enrolled stable, nonacute adult patients presenting with typical or atypical symptoms suggestive of obstructive coronary artery disease from 21 US primary care practices from August 2012 to August 2014. Demographics, clinical characteristics, and ASGES results (predefined as low [ASGES ≤15] or elevated [ASGES >15]) were collected, as were referrals to Cardiology or further functional/anatomic cardiac testing after ASGES testing. Patients were followed for 1 year post ASGES testing. Among the 566-patient cohort (median age 56 years), clinicians referred 26/252 (10%) of patients with low scores vs 137/314 (44%) of patients with elevated scores to Cardiology or advanced cardiac testing for further evaluation (unadjusted odds ratio 0.15, P clinical covariates = 0.18, P advanced cardiac testing showed abnormal findings in 0 of 13 (0%) low ASGES and 10 of 71 (14%) elevated ASGES patients.

    Liver injury due to bile duct ligation (BDL) is histologically characterized by cholestasis, bile ductular proliferation, hepatocellular damage, portal fibrosis, and ultimately biliary cirrhosis. Stem cells within the liver may act as progenitor cells for small epithelial cells termed oval cells that can differentiate into bile duct cells or hepatocytes, whereas myofibroblasts are the principal source of collagen production in fibrosis. The aims of this study were to determine 1) whether BDL ...

    The natural history of portal cavernoma cholangiopathy (PCC) in patients with significant biliary obstruction (SBO) who cannot undergo shunt surgery, is not known. We therefore, analyzed data of patients of extra-hepatic portal venous obstruction (EHPVO) with PCC. Prospectively recorded details of 620 (age 21.2 [11.4] years; 400 [65%] males) patients with primary EHPVO were reviewed. Outcomes (hepatic decompensation/mortality) of patients with PCC and SBO without shuntable veins were noted at follow up of 7 [4-11] years. Ninety-seven of 620 (15.6% [60 men]) EHPVO patients had PCC-SBO. Of these 57 did not have shuntable veins. The median duration from any index symptom to symptomatic PCC was 7 (0-24) years and from index bleed to symptomatic PCC was and 12 (5-24) years, respectively. Thirteen patients underwent endoscopic retrograde cholangiography; nine repeatedly over 7 (4-10) years. Decompensation was seen in 5 patients. Presentation other than variceal bleed was associated with hepatic decompensation (5/19 versus 0/38, P = 0.003). Majority of patients with PCC-SBO do not have shuntable veins, and may have good long-term outcomes. Patients presenting with variceal bleed have low chance of decompensation. Symptomatic PCC appears to be a late event in EHPVO.

    Biliary endoprosthesis could provide permanent internal biliary drainage in patient with obstructive jaundice with advantages of absence of troublesome external catheter and no loss of fluid, bile and electrolytes over external drainage. Incidence of sepsis and cholangitis be lowered. Endoprosthesis was performed in 18 patients of obstructive jaundice from January, 1985 to December, 1985 at Department of Radiology, Kyungpook National University Hospital. The results are as follows 2. The cases of obstructive jaundice included bile duct cancer in 11, stomach ca. metastasis in 3, ca. of ampulla of Vater in 1, ca. of head of pancreas in 1, CBD cancer with postop. recurrence in 1, and impacted CBD stone in 1 case. 2. The levels of obstruction were at the trifurcation in 8, CHD in 5, proximal CBD in 3, and distal CBD in 2 cases. 3. Decline of serum bilirubin level was noted in 15 cases with the most rapid decline within 1 week after the procedure. 4. The complication occurred in 5 cases. The three cases were recovered spontaneously, but one died of bile peritonitis, another experienced obstruction of endoprosthesis. 5. The endoprosthesis is beneficial in treatment of obstructive jaundice for which surgery is not indicated, and saving expensive abdominal surgery and less advantageous percutaneous external drainage, hence enhancing life quality.

    AIM: To investigate the effect of biliary drainage on inducible nitric oxide synthase (iNOS), CD14 and TGR5 expression in rats with obstructive jaundice (OJ). METHODS: Male adult Sprague-Dawley rats were randomly assigned to four groups: OJ, sham operation (SH), internal biliary drainage (ID) and external biliary drainage (ED). Rat models were successfully established by two operations and succumbed for extraction of Kupffer cells (KCs) and liver tissue collection on the 8th and 15th day. KCs were isolated by in situ hepatic perfusion and digested with collagen IV, density gradient centrifuged by percoll reagent and purified by cell culture attachment. The isolated KCs were cultured with the endotoxin lipopolysaccharide (LPS) with and without the addition of ursodeoxycholic acid (UDCA). The expression of iNOS, CD14 and bile acid receptor-TGR5 protein in rat liver tissues was determined by immunohistochemistry. The expression of iNOS and CD14 messenger RNA (mRNA) on the isolated KCs was detected by reverse transcription polymerase chain reaction (PCR) and the TGR5 mRNA level in KCs was measured by real-time quantitative PCR. RESULTS: The iNOS protein was markedly expressed in the liver of OJ rats, but rare expressed in SH rats. After relief of OJ, the iNOS expression was decidedly suppressed in the ID group (ID vs OJ, P < 0.01), but obviously increased in rats of ED (ED vs OJ, P = 0.004). When interfered only with LPS, the expression of iNOS mRNA by KCs was increased in the OJ group compared with the SH group (P = 0.004). After relief of biliary obstruction, the iNOS mRNA expression showed slight changes in the ED group (ED vs OJ, P = 0.71), but dropped in the ID group (ID vs OJ, P = 0.001). Compared with the simple intervention with LPS, the expressions of iNOS mRNA were significantly inhibited in all four groups after interfered with both LPS and UDCA (P < 0.01, respectively). After bile duct ligation, the CD14 protein expression in rat liver was significantly

    OBJECTIVE To evaluate the usefulness of noncontrast abdominal CT and abdominal ultrasonography for the detection of mechanical gastrointestinal obstruction in dogs and compare intestinal diameter ratios between dogs with and without obstruction. DESIGN Controlled trial. ANIMALS 16 client-owned dogs with physical and radiographic findings consistent with mechanical gastrointestinal obstruction. PROCEDURES Abdominal ultrasonography and CT were performed for all dogs, followed by laparoscopy and exploratory laparotomy. Time required for image acquisition and presence and location of gastrointestinal obstruction were assessed with both imaging modalities. Findings were compared with those of exploratory surgery. Maximum and minimum intestinal diameters were recorded on CT scans; values were converted to a ratio and compared between dogs with and without obstruction. RESULTS Results of abdominal CT and exploratory surgery for the diagnosis of mechanical obstruction agreed for all 16 dogs; 10 dogs had complete obstruction, 3 had partial obstruction, and 3 had no obstruction. In 1 dog with functional ileus, abdominal ultrasonography resulted in an incorrect diagnosis of mechanical obstruction. Median (interquartile range) image acquisition time for abdominal CT (2.5 minutes [2.0 to 3.8 minutes]) was markedly and significantly shorter than that for ultrasonography (26.0 minutes [22.0 to 35.8 minutes]). In both dorsal and transverse CT planes, dogs with gastrointestinal obstruction (partial or complete) had significantly larger intestinal diameter ratios than dogs without obstruction. CONCLUSIONS AND CLINICAL RELEVANCE Abdominal CT was feasible, rapid, and accurate for the diagnosis of mechanical obstruction in dogs with clinical signs and physical examination findings consistent with partial or complete gastrointestinal obstruction.

    To characterize in vitro coagulation status in a cohort of dogs with extrahepatic biliary tract obstruction (EHBO) and to evaluate these patients for hypercoagulability by means of thromboelastography. Prospective cohort study. Animals-10 dogs with EHBO and 19 healthy control dogs. Partial or complete EHBO was confirmed via exploratory celiotomy. Venous blood samples were collected for evaluation of prothrombin time (PT) and activated partial thromboplastin time (APTT); fibrinogen and D-dimer concentrations; protein C and antithrombin activities; and factor VII, VIII, and XI coagulant activities in plasma as well as thromboelastography in whole blood. Thromboelastography variables were measured from the thromboelastography tracing, and a coagulation index was calculated. Thromboelastography results were compared with those of healthy control dogs previously evaluated by the same laboratory. Hypercoagulability was diagnosed in all dogs with EHBO on the basis of a high coagulation index. Thromboelastography variables, including maximal amplitude, α-angle, and coagulation index, were significantly higher, and K (clot formation time) and R (reaction time) were significantly lower in these dogs than in control dogs. All dogs with EHBO had PT and APTT within respective reference ranges. Plasma D-dimer and fibrinogen concentrations were above reference ranges in 8 and 7 dogs, respectively, and protein C and antithrombin activities were below reference ranges in 3 and 1 dogs, respectively. In vitro hypercoagulability was commonly detected in dogs with naturally occurring EHBO. The traditional view of EHBO as a disease that causes hypocoagulability may need to be reconsidered.

    Controversy exists over the need for unilateral versus bilateral stent placement in patients with malignant obstruction at the biliary hilum. Placement of bilateral uncovered self-expanding metal stent (UCSEMS) at this location is technically challenging, and generally associated with lower rates of procedural success. Serial insertion of side-by-side UCSEMS may be especially difficult when simultaneous deployment is not possible using larger stent delivery catheters. In this single-center, retrospective case series of all patients who underwent bilateral placement of uncovered Wallflex(TM) biliary stents between July 2008 and July 2014, we evaluate the feasibility, technical success, and safety of patients undergoing serial insertion of bilateral UCSEMS using the 8 Fr Wallflex(TM) biliary system for malignant hilar obstruction. A total of 17 patients were included. Primary cholangiocarcinoma, Bismuth IV, was the most common diagnosis. Mean procedure time was 54.4 minutes. Overall procedural technical success was achieved in 17/17 patients. Stricture dilation was necessary prior to Wallflex(TM) insertion in 8/17 patients (47.1%). Transpapillary extension of two stents was performed in all patients. There were no cases of stent deployment malfunction, or inability to insert or deploy the 2(nd) stent. Nine of 17 patients (52.9%) required inpatient hospitalization following ERCP; the most common indications were abdominal pain and need for IV antibiotics. There was one case of ERCP-related cholangitis otherwise; there were no other major complications. Bilateral, serial insertion of UCSEMS using the 8 Fr Wallflex(TM) biliary system in malignant hilar obstruction is feasible with an excellent technical success profile. Using this device for side-by-side deployment of UCSEMS appears to be safe in the majority of patients.

    The excellent results of new devices like the new bipolar feedback-controlled sealing system (LigaSure) for closure of blood vessels encouraged surgeons to use these instruments for other structures like bile ducts. The aim of this study was to evaluate the feasibility of closure of cystic duct in case of biliary obstruction. Ten domestic pigs underwent laparoscopic cholecystectomy sealing the cystic duct with LigaSure. The common bile duct was closed with an endoclip to create a biliary hypertension. On the 12th postoperative day blood samples were taken for liver enzymes. At autopsy on day 15 the pigs were investigated for bile leaks or biliary peritonitis. The cystic duct was resected for histological examination. Seven pigs survived, one pig died during introduction of anesthesia, one on the 1st and one on the 2nd postoperative day without any findings at the autopsy. One pig out of 7 had a bile leak; the other 6 were without any sign of leakage. Histologically 3 pigs had a regular coagulation zone at the cystic duct, 3 had a total necrosis, one a partial necrosis of the mucosa only. Though there was only one insufficiency, the feedback-controlled bipolar vessel sealer cannot be recommended for biliary surgery with regard to the high rate of necrosis stated in our experiment.

    Common bile duct stenosis owing to extrahepatic portal varices is termed "portal hypertensive biliopathy" (PHB) and is a rare occurrence. We report a case of PHB owing to portal vein thrombosis with cavernous transformation successfully managed by mesocaval shunt and endoscopic retrograde cholangiopancreatography (ERCP) biliary stent placement. A 44-year-old male, who presented with hematemesis, melena, jaundice, and abdominal pain, underwent gastroscopy, which revealed bleeding gastric varices. Computed tomography with arterial and venous imaging demonstrated portal vein thrombosis with cavernous transformation and extensive extrahepatic varices within the porta hepatis causing common bile duct obstruction from extrinsic compression. Biliary decompression was achieved with ERCP, and a small common bile duct stone was retrieved. A mesocaval shunt with a 16 mm Dacron graft successfully treated the portal hypertension. PHB is rare. We report a case successfully treated by mesocaval shunt and ERCP.

    Assays that measure the serum level of carbohydrate antigen 19-9 (CA19-9) are used to screen patients with primary sclerosing cholangitis (PSC) for malignancies. However, in patients with PSC, cholestasis, and bacterial cholangitis, the CA19-9 level can be affected by variants in the fucosyltransferases 2 and 3 genes (FUT2 and FUT3), which regulate the production of CA19-9. We investigated how these genotypes affect cancer screening in these patients. We performed a retrospective analysis of data from 209 patients with PSC (19 patients with biliary malignancy, 23 patients with cholestasis and bacterial cholangitis) treated at the University Hospital Heidelberg from 1987 through 2014. We collected data on the maximum serum level of CA19-9; laboratory measures of cholestasis or inflammation; the presence of dominant stenosis, cholestasis, and bacterial cholangitis; and FUT2 and FUT3 genotypes. Patients were assigned to intermediate (n = 161) or high (n = 48) CA19-9 biosynthesis groups, based on FUT2 and FUT3 genotypes. Patients incapable of CA19-9 biosynthesis, based on genetic features, were excluded. The median level of CA19-9 was 31.1 U/mL in cancer-free patients. The CA19-9 level correlated with the level of C-reactive protein (P cholangitis (7.8 U/mL), followed by patients with only obstruction (28.0 U/mL), and then patients with cholestasis and bacterial cholangitis (77.0 U/mL and 205.4 U/mL in patients without or with concomitant obstruction, respectively). The greatest increase in CA19-9 as a result of cholestasis and bacterial cholangitis was observed in patients in the high CA19-9 biosynthesis group. In patients with PSC, cholestasis has little effect on the level of CA19-9, but cholestasis and bacterial cholangitis increase the level. Their effects on CA19-9 level depend on the FUT2 and FUT3 genotype. These findings support the analysis of FUT2 and FUT3 genotype during follow-up evaluation of patients with PSC.

    Patients with biliary obstruction are at high risk to develop septic complications after endoscopic retrograde cholangiography (ERC). We evaluated the benefits of local application of antimicrobial agents into ERC contrast media in preventing post-ERC infectious complications in a high-risk study population. Patients undergoing ERC at our tertiary referral center were retrospectively included. Addition of vancomycin, gentamicin and fluconazol into ERC contrast media was evaluated in a case-control design. Outcomes comprised infectious complications within 3 days after ERC. In total, 84 ERC cases were analyzed. Primarily indications for ERC were sclerosing cholangitis (75%) and malignant stenosis (9.5%). Microbial testing of collected bile fluid in the treatment group was positive in 91.4%. Detected organisms were sensitive to the administered antimicrobials in 93%. The use of antimicrobials in contrast media was associated with a significant decrease in post-ERC infectious complications compared to non-use (14.3% vs. 33.3%; odds ratio [OR]: 0.33, 95% confidence interval [CI]: 0.114-0.978). After adjusting for the variables acute cholangitis prior to ERC and incomplete biliary drainage, the beneficial effect of intraductal antibiotic prophylaxis was even more evident (OR = 0.153; 95% CI: 0.039-0.598, p = 0.007). Patients profiting most obviously from intraductal antimicrobials were those with secondary sclerosing cholangitis. Local application of a combination of antibiotic and antimycotic agents to ERC contrast media efficiently reduced post-ERC infectious events in patients with biliary obstruction. This is the first study that evaluates ERC-related infectious complications in patients with secondary sclerosing cholangitis. Our first clinical results should now be prospectively evaluated in a larger patient cohort to improve the safety of ERC, especially in patients with secondary sclerosing cholangitis.

    To evaluate the usefulness and safety of percutaneous transluminal forceps biopsy in patients suspected of having a malignant biliary obstruction. Forty consecutive patients (21 men and 19 women; mean age, 71.9 years) underwent forceps biopsy through percutaneous transhepatic biliary access performed to drain bile. Lesions involved the common bile duct (n 8), common hepatic duct (n 18), hilum (n 6), ampullary segment of the common bile duct (n 8) and were biopsied with 7-F biopsy forceps. Final diagnosis was confirmed with pathologic findings at surgery, or clinical and radiologic follow-up. Twenty-one of 40 biopsies resulted in correct diagnosis of malignancy. Thirteen biopsy diagnosis were proved to be true-negative. There were six false-negative and no false-positive diagnoses. Sensitivity, specificity and accuracy in aspecific biliary obstructions were 85%, 100% and 88,7% respectively. Sensitivity of biopsy in malignancies was higher than in benign obstructions (100% vs 68,4%, CI = 95%). Sensitivity was lower in the hilum tract and in the common bile duct than in other sites (CI = 95%). No major complications related to biopsy procedures occurred. Percutaneous transluminal forceps biopsy is a safe procedure, easy to perform through a transhepatic biliary drainage tract, providing high accuracy in the diagnosis of malignant biliary obstructions.

    To characterize biliary abnormalities seen in portal cavernoma cholangiopathy (PCC) on MR cholangiopancreaticography (MRCP) and elucidate certain salient features of the disease by collaborating our findings with those of previous studies. We prospectively enrolled 52 patients with portal cavernoma secondary to idiopathic extrahepatic portal vein obstruction, who underwent a standard MRCP protocol. Images were analyzed for abnormalities involving the entire biliary tree. Terms used were those proposed by the Indian National Association for Study of the Liver. Angulation of the common bile duct (CBD) was measured in all patients with cholangiopathy. Cholangiopathy was seen in 80.7% of patients on MRCP. Extrahepatic ducts were involved in 95% of patients either alone (26%) or in combination with the intrahepatic ducts (69%). Isolated involvement of the intrahepatic ducts was seen in 4.8% of patients. Abnormalities of the extrahepatic ducts included angulation (90%), scalloping (76.2%), extrinsic impression/indentation (45.2%), stricture (14.3%) and smooth dilatation (4.8%). The mean CBD angle was 113.2 ± 19.8°. Abnormalities of the intrahepatic ducts included smooth dilatation (40%), irregularity (28%) and narrowing (9%). Cholelithiasis, choledocholithiasis and hepatolithiasis were seen in 28.6% (12) patients, 14.3% (6) patients and 11.9% (5) patients, respectively. There was a significant association between choledocholithiasis and CBD stricture, with no significant association between choledocholithiasis and cholelithiasis. A significant association was also seen between hepatolithiasis and choledocholithiasis. The spectrum of biliary abnormalities in PCC has been explored and some salient features of the disease have been elucidated, which allow a confident diagnosis of this entity. Advances in knowledge: PCC preferentially involves the extrahepatic biliary tree. Changes in the intrahepatic ducts generally occur as sequelae of involvement of the extrahepatic

    OBJECTIVE The purpose of this study was to compare the decisions regarding the need for furosemide made by two independent renal decision support systems, RENEX and CARTAN, with the need for furosemide determined in clinical practice and by expert reviewers using the baseline plus furosemide protocol. SUBJECTS AND METHODS RENEX and CARTAN are independent decision support systems that reach their conclusions without operator input. RENEX is a knowledge-based system and CARTAN is a statistical decision support system. Both were trained using the same pilot group of 31 adult patients (61 kidneys) referred for suspected obstruction. Subsequently, both systems were prospectively applied to 102 patients (200 kidneys) of whom 70 received furosemide; decisions regarding the need for furosemide were compared with the clinical decisions and the decisions of three experts who independently scored each kidney on the need for furosemide. Differences were resolved by consensus. RESULTS RENEX agreed with the clinical and experts’ decisions to give furosemide in 97% (68/70) and 98% (65/66) of patients, respectively, whereas CARTAN agreed in 90% (63/70) and 89% (59/66), respectively, p furosemide in 78% of kidneys (87/111), whereas RENEX agreed in only 69% of kidneys (77/111), p = 0.008. CONCLUSION Use of RENEX or CARTAN as decision support tools in the baseline plus furosemide protocol has the potential to help the radiologist avoid unnecessary imaging and reduce the technologist, computer, camera, and physician time required to perform the procedure.

    Mirizzi's syndrome is a rare complication of chronic vesicular lithiasis with prevalence ranging from 0.7% to 1.4% among patients who have undergone cholecystectomy. It is characterized by cholestatic icterus associated with compression of the common bile duct due to lodged calculus in the vesicular neck or in the cystic duct. The disease can evolve toward the erosion through the common hepatic duct wall and, therefore, it can cause the formation of a gallbladder-biliary fistula. We here report a case of Mirizzi's syndrome type I in order to highlight the role of preoperative diagnosis which is made easier by endoscopic retrograde cholangiography or by cholangio-MRI, allowing to avoid iatrogenic bile duct injuries. We conducted a review of the available literature on various aspects of this syndrome, including its pathogenesis, diagnosis and management.

    Ultrasonic devices with rapid image build-up and high power of resolution enable detailed assessment of the vascular and biliary structures. Visualisation of the biliary tract of normal lumen in the extrahepatic region enables identification of a biliary obstruction at a time where dilatation of the intrahepatic biliary tract has not yet taken place. The identification of small visceral branches of the aorta abdominalis as well as of portal and systemic veins yields sonographically reliable vascular points of reference which enable, apart from the exact localisation of the biliary tract and of the pancreas, accurate topographic identification of abdominal mass lesions.

    Full Text Available Increased amounts of intestinal endotoxin are absorbed in obstructive jaundice. The precise mechanism is not known but the increased absorption may arise from alterations in the luminal contents, in the intestinal flora, in the gut wall or in interactions between all three. To examine the effects of the intestinal flora we have compared the morphological changes in the small intestine in obstructive jaundice in germ free and conventional rats while the effects of bile constituents have been examined by addition of bile constituents to the diet of bile duct ligated rats. Changes in the intestine were examined, histologically, by enzyme histochemistry, and by transmission and scanning electron microscopy. The results showed no differences in response between germ free and conventional rats. Feeding of diets containing bile salts exacerbated the lesion. Feeding of diets containing cholesterol, however, reduced the degree of intestinal changes produced by cholestasis and completely antagonised the increase in damage caused by feeding of bile salts.

    Biliary MRI is a relatively new diagnostic test in the arsenal of exploration techniques in biliopancreatic pathology. This is a reproducible and reliable non invasive technique for direct visualization of biliary and pancreatic ducts. This study aims to evaluate the morphological features of major abnormalities and the role of biliary MRI in the etiological diagnosis of cholestatic icteruses. This is a retrospective study of 17 patients conducted in the Imaging Unit of the University Hospital of Fann and of the Principal hospital of Dakar over a period of 4 years and six months (January 2008 at July 2012). All patients underwent MRI (1.5T) according to the standardized protocols for the explored pathology. Only medical records of patients whose diagnosis was established based on laboratory tests and who underwent biliary MRI and surgical exploration were retained. The study involved 5 women and 12 men with a sex ratio of 2.4. The average age of patients was 58 years, ranging between 35 and 81 years. Klatskin tumors were found in 7 patients with infiltrative form in 71% of cases and exophytic form was found in 28% of cases. Cancers of the gallbladder were found in 28% of cases. Cancers in the head of the pancreas accounted for 28% of cases. Major bile duct lithiasis was detected in 5 patients, choledocholithiasis in 60% of cases and a single lithiasis in 40% of cases. All these lesions were responsible for an expansion of intrahepatic bile duct (IHBD). One case of intra and extrahepatic bile ducts dilatation was found without biliopancreatic cause. Biliary MRI is the test of choice for the exploration of cholestatic icteruses. It should be recommended as first-line examination when residual lithiasis is suspected and as second-line examination after ultrasound, when the latter shows a suspected bile ducts tumoral obstruction. Its association with CT scan is the best combination of screening tests for etiologic diagnosis and pre-operative assessment of tumoral

    Iridium 192 seeds contained in a ribbon were preloaded into a new double lumen 11 Fr endoprosthesis which was then inserted into malignant strictures of the bile duct and ampulla and left in place for 48 hours until 5000 rads were delivered to the tumor. The procedure was carried out in 14 patients (7 women, 7 men; mean age, 63.2 years; range, 46 to 86 years). Six patients were treated for cholangiocarcinomas, four with pancreatic carcinomas, and four with ampullary carcinomas. No complications occurred. The mean survival of the group was 7 months (range, 3 days to 27 months). This new technique provides both intraluminal brachytherapy and biliary drainage and is inserted intraduodenally across the papilla of Vater avoiding puncture of the liver and external hardware required by the percutaneous technique and hardware necessitated with a nasobiliary tube. Following removal of the iridium prosthesis, a large caliber endoprosthesis is inserted for continued decompression. Because of proven efficacy of endoprostheses, this new technique should be considered when intraluminal irradiation is indicated.

    AimTo investigate and compare the efficacy and safety of percutaneous transhepatic biliary stenting (PTBS) using a one- or two-stage procedure and determine the predictive factors for the efficacious treatment of malignant hilar obstruction (MHO).Methods159 consecutive patients with MHO who underwent PTBS were enrolled between January 2010 and June 2013. Patients were classified into one- or two-stage groups. Independent predictors of therapeutic success were evaluated using a logistic regression model.Results108 patients were treated with one-stage PTBS and 51 patients were treated with two-stage PTBS. The stents were technically successful in all patients. Successful drainage was achieved in 114 patients (71.4 %). A total of 42 early major complications were observed. Re-interventions were attempted in 23 patients during follow-up. The cumulative primary patency rates at 3, 6, and 12 months were 88, 71, and 48 %, respectively. Stent placement using a one- or two-stage procedure did not significantly affect therapeutic success, early major complications, median stent patency, or survival. A stent placed across the duodenal papilla was an independent predictor of therapeutic success (odds ratio = 0.262, 95 % confidence interval [0.107–0.642]). Patients with stents across papilla had a lower rate of cholangitis compared with patients who had a stent above papilla (7.1 vs. 20.3 %, respectively, p = 0.03).ConclusionsThe majority of patients with MHO who underwent one-stage PTBS showed similar efficacy and safety outcomes compared with those who underwent two-stage PTBS. Stent placement across the duodenal papilla was associated with a higher therapeutic success rate.

    Objective: to determine the usefulness of magnetic resonance cholangiopancreatography (MRCP) in the diagnoses of bile duct injuries following cholecystectomy. Material and method: MRCP was retrospectively evaluated in 40 patients with suspected bile duct injury after laparoscopic or conventional cholecystectomy. Eight of these patients had been submitted to biliary reconstruction. All patients were symptomatic (jaundice, fever and chills, weight loss and abdominal pain). The scans were independently reviewed by two radiologists. The results were confirmed by surgery, percutaneous drainage, endoscopic retrograde cholangiopancreatography and clinical follow-up. The level and severity of bile duct injury were rated according to the Bismuth classification. Results: in a total of 40 symptomatic patients, 10 (25%) had normal findings on MRCP; Postoperative complications were seen in 29 (72.5%) patients, seven of them with more than one finding. Pancreatic head neoplasia was diagnoses in one patient. The most frequent finding was sclerosing (41.4%) followed by biliary duct stenosis (34.5%), residual or recurrent biliary stones (31.0%) and fluid collections (17.2%). The images obtained by MRCP were considered of good quality. Conclusion: MRCP is an effective method for the evaluation of patients with suspected postcholecystectomy biliary tract complications.

    Biliary sludge was first described with the advent of ultrasonography in the 1970s. It is defined as a mixture of particulate matter and bile that occurs when solutes in bile precipitate. Its composition varies, but cholesterol monohydrate crystals, calcium bilirubinate, and other calcium salts are the most common components. The clinical course of biliary sludge varies, and complete resolution, a waxing and waning course, and progression to gallstones are all possible outcomes. Biliary sludge may cause complications, including biliary colic, acute pancreatitis, and acute cholecystitis. Clinical conditions and events associated with the formation of biliary sludge include rapid weight loss, pregnancy, ceftriaxone therapy, octreotide therapy, and bone marrow or solid organ transplantation. Sludge may be diagnosed on ultrasonography or bile microscopy, and the optimal diagnostic method depends on the clinical setting. This paper proposes a protocol for the microscopic diagnosis of sludge. There are no proven methods for the prevention of sludge formation, even in high-risk patients, and patients should not be routinely monitored for the development of sludge. Asymptomatic patients with sludge can be managed expectantly. If patients with sludge develop symptoms or complications, cholecystectomy should be considered as the definitive therapy. Further studies of the pathogenesis, natural history, and clinical associations of biliary sludge will be essential to our understanding of gallstones and other biliary tract abnormalities.

    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 intestinum, so that control examinations can even be negative.

    Full Text Available Pediatric Spontaneous Bile duct perforation is a rare clinical condition with only around 150 cases reported worldwide. Early management gives excellent prognosis but the condition often presents a diagnostic dilemma. Hepato-biliary Technetium-99m-iminodiacetic acid scintiscan is the diagnostic investigation of choice but its availability in third world countries is limited. We present two cases of spontaneous biliary peritonitis in children, which were diagnosed without scintiscanning. The first case was a one-and -a half-year-old child, who was diagnosed with biliary peritonitis without pneumoperitoneum by a combination of Ultrasound (USG, Contrast enhanced computed tomography (CECT, and Magnetic Resonance Imaging (MRI. The child underwent USG-guided drainage and subsequent cholecystectomy with hepatico-jejunostomy. The second child also had biliary peritonitis without pneumoperitoneum, which was initially suspected on USG. CECT revealed dilated gall bladder and fluid collection in sub-hepatic space and pelvis. Abdominal paracentesis revealed presence of bile. The child responded to conservative therapy. Both are doing well on two-year follow-up. In a patient with jaundice, biliary tract abnormalities and/or free fluid, either generalized or localized to peri-cholecystic/sub-hepatic space on USG/CT/MRI, in the absence of pneumoperitoneum, suggest a diagnosis of biliary perforation even in the absence of scintiscanning.

    Full Text Available Introduction. Sharp, retained foreign bodies in the oesophagus are associated with severe complications. Developmentally delayed patients are especially subject to foreign objects. We describe a 37-year-old, developmentally delayed male with a mincer blade obstructing the oesophagus. Six months prior to surgical intervention, the patient was hospitalized in a condition of sepsis and pneumonia where the thoracic X-ray reveals a foreign body in the proximal oesophagus. When rehospitalized 6 months later, a mincer blade of the type used in immersion blenders was surgically removed. During these 6 months the patient’s main symptoms were dysphagia, weight loss, and diarrhoea. When developmentally delayed patients present with dysphagia, we strongly encourage the awareness of the possible presence of foreign bodies. To our knowledge this is the first reported case of a mincer blade in the oesophagus.

    Full Text Available Ascaris lumbricoides, or the common roundworms, has a worldwide distribution but is mainly seen in Asian and Latin American countries. In humans the usual habitat is in the small intestine, mainly in the jejunum. But if the worm load is high, which may go up to a thousand worms, the worms tend to migrate away from the usual site of habitat. This brief paper aims at highlighting the condition of biliary ascariasis through the authors′ experience in managing three such cases over a period of 1 year. The clinical features which arouse suspicion of biliary ascariasis, as well as diagnostic modalities and management, are described. Initially the cases were managed conservatively, but we conclude that if worms are retained in biliary tree for more than 10 days, surgery should be performed; since retention of degraded and calcified dead worm can occur, and this can lead to complications which are difficult to manage.

  12. Percutaneous transhepatic biliary endoprostheses

    1985-03-01

    Eighty biliary endoprostheses were introduced by the transhepatic route in sixty patients with obstructive jaundice. Complication rate was 21% (no mortality). Average survival time is sixteen weeks (maximum 53 weeks). In most patients, a 12 F teflon endoprosthesis was introduced four to five days after the initial catheter drainage. Patients in poor condition had a primary implant of a 9 F endoprosthesis. A combined transhepatic/transoral implantation was carried out five times. Results have shown that implantation of a prosthesis is as effective as a surgical bypass operation for palliation of obstructive jaundice and that it is better than catheter drainage. In-vitro experiments have indicated that failure of a 12 F prosthesis due to encrustation may be expected in about 23 weeks. This is in line with the survival time of patients with carcinomas.

    2011-01-01

    Biliary cystadenoma is a very rare benign cystic tumour of the liver. Fewer than 150 cases have been described in the literature so far. The authors present a case of a 29-year-old female with a giant intrahepatic biliary cystadenoma who presented with abdominal pain and obstructive jaundice. The patient was treated with left hepatectomy and now 12 months after the surgery she is in good condition with no signs of recurrence of the disease. Clinical presentation of biliary cystadenoma is not specific. Diagnosis is based on imaging methods, mainly ultrasound and CT scan. However, it is often misdiagnosed. For treatment, radical resection is advocated because a biliary cystadenoma is considered to be a premalignant lesion. The prognosis of biliary cystadenoma after complete resection is excellent. Nevertheless, there is a risk of recurrence or malignant transformation after incomplete resection.

    Even in the presence of intrahepatic metastases or previous failure of biliary enteric anastomosis, patients suffering from malignant obstructive jaundice can bve given relief by biliary endoprosthesis. Mean survival time is four months. Other than with a catheter drain, spetic cholangitis is rarely observed after the insertion of an endoprosthesis. The intervention's risk will hardly be augmented by drainage of both lobes as often necessary.

    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. The most usual treatment nowadays is resection of the bile duct, together with cholecystectomy and Roux-en-Y reconstruction. PMID:19630118

    2008-01-01

    Full Text Available Biliary atresia (BA is a cholangiodestructive disease affecting biliary tract, which ultimately leads to cirrhosis, liver failure and death if not treated. The incidence is higher in Asian countries than in Europe. Up to 10% of cases have other congenital anomalies, such as polysplenia, asplenia, situs inversus, absence of inferior vena cava and pre-duodenal portal vein, for which we have coined the term Biliary Atresia Splenic Malformation (BASM syndrome. For these infants the aetiology lies within the first trimester of gestation. For others affected with BA, aetiology is more obscure and perinatal destruction of fully-formed ducts perhaps by the action of hepatotropic viruses has been suggested. Whatever the cause, the lumen of the extrahepatic duct is obliterated at a variable level and this forms the basis for the commonest classification (Types I, II, III. All patients with BA present with varying degree of conjugated jaundice, pale non-pigmented stools and dark urine. Key diagnostic tests include ultrasonography, biochemical liver function tests, viral serology, and (in our centre a percutaneous liver biopsy. In some centres, duodenal intubation and measurement of intralumenal bile is the norm. Currently BA is being managed in two stages. The first stage involves the Kasai operation, which essentially excises all extrahepatic biliary remnants leaving a transected portal plate, followed by biliary reconstruction using a Roux loop onto that plate as a portoenterostomy. If bile flow is not restored by Kasai procedure or life-threatening complications of cirrhosis ensue then consideration should be given to liver transplantation as a second stage. The outcome following the Kasai operation can be assessed in two ways: clearance of jaundice to normal values and the proportion who survive with their native liver. Clearance of jaundice (< 2 mg/dL or < 34 µmol/L after Kasai has been reported to be around 60%, whereas five years survival with

    Purpose: To assess the accuracy of cytological sampling and forceps biopsy in obstructing biliary lesions and to identify factors predictive of success. Methods: Consecutive patients (n = 119) with suspected malignant inoperable obstructive jaundice treated with percutaneous transhepatic biliary drainage during 7 years were included (60 male; mean age 72.5 years). All patients underwent forceps biopsy plus cytological sampling by washing the forceps device in cytological solution. Patient history, procedural and pathological records, and clinical follow-up were reviewed. Statistical analysis included chi-square test and multivariate regression analysis. Results: Histological diagnosis after forceps biopsy was more successful than cytology: Sensitivity was 78 versus 61%, and negative predictive value was 30 versus 19%. Cytology results were never positive when the forceps biopsy was negative. The cytological sample was negative and forceps sample positive in 2 cases of cholangiocarcinoma, 16 cases of pancreatic carcinoma, and 1 case of benign disease. Diagnostic accuracy was predicted by low bilirubin (p < 0.001), aspartate transaminase (p < 0.05), and white cell count (p {<=} 0.05). Conclusions: This technique is safe and effective and is recommended for histological diagnosis during PTBD in patients with inoperable malignant biliary strictures. Diagnostic yield is greater when bilirubin levels are low and there is no sepsis; histological diagnosis by way of forceps biopsy renders cytological sampling unnecessary.

    Percutaneous Transhepatic Biliary Catheterization is commonly employed in the diagnosis and management of obstructive jaundice associated with malignant lesions. Tumor manipulation as an effort to obtain a histological diagnosis or to establish short or long-term internal-external biliary drainage is liable to disseminate the malignancy along the catheter tract. Two cases of malignant seeding of the catheter tract after biliary drainage have been observed.

    Full Text Available Objective. To assess the screening tools in snoring patients. Material and Methods. A retrospective review of data was conducted from children between 2 and 15 years old who were referred on suspicion of obstructive sleep apnea-hypopnea (OSAH between June 2008 and June 2011. We excluded patients with significant comorbidities. Pediatric Sleep Questionnaire (PSQ, physical exam (PE, and pulse-oximetry data were collected and correlated with the results of the nightly polygraph at home. Results. We selected 98 patients. The 22-item version of the PSQ had sensitivity of 96% and specificity of 36.8%. The overall value of the clinic predictor of OSAH (PSQ and PE together exhibited an increased specificity 57.6% with 94.6% of sensitivity. The nocturnal home oximetry method used alone was very specific, 92.1%, but had a lower sensitivity, 77.1%. The set of clinical assessment tools used together with pulse-oximetry screening provided excellent specificity 98.1% and a positive predictive value 94.1% globally. The performance of this screening tool is related with the severity of OSAH and accuracy is better in moderate and severe cases. Conclusion. The combination of clinical assessment and pulse-oximetry screening can provide a sufficient diagnostic approach for pediatric patients with suspected OSAH at least in moderate and severe cases.

    We report a 71-year-old man who had undergone pylorus-preserving pancreatoduodenectomy (PPPD) using PPPD-IV reconstruction for cholangiocarcinoma. For 6 years thereafter, he had suffered recurrent cholangitis, and also a right liver abscess (S5/8), which required percutaneous drainage at 9 years after PPPD. At 16 years after PPPD, he had been admitted to the other hospital because of acute purulent cholangitis. Although medical treatment resolved the cholangitis, the patient was referred to our hospital because of dilatation of the intrahepatic biliary duct (B2). Peroral double-balloon enteroscopy revealed that the diameter of the hepaticojejunostomy anastomosis was 12 mm, and cholangiography detected intrahepatic stones. Lithotripsy was performed using a basket catheter. At 1 year after lithotripsy procedure, the patient is doing well. Hepatobiliary scintigraphy at 60 minutes after intravenous injection demonstrated that deposit of the tracer still remained in the upper afferent loop jejunum. Therefore, we considered that the recurrent cholangitis, liver abscess, and intrahepatic lithiasis have been caused by biliary stasis due to nonobstructive afferent loop syndrome. Biliary retention due to nonobstructive afferent loop syndrome may cause recurrent cholangitis or liver abscess after hepaticojejunostomy, and double-balloon enteroscopy and hepatobiliary scintigraphy are useful for the diagnosis of nonobstructive afferent loop syndrome.

    No treatment is recommended for silent gallstones. The diagnosis of acute cholecystitis is based on clinical and biological signs and on abdominal sonography. Early laparoscopic cholecystectomy is the treatment of choice, except in case of severe (grade III) cholecystitis where a percutaneous cholecystostomy associated with antibiotic therapy is recommended. The diagnostic accuracy of abdominal sonography for the diagnosis of common bile duct stones is poor. A second-line MR cholangiopancreatography or an endoscopic sonography is often needed to confirm the diagnosis. The treatment of acute cholangitis is based on both antibiotic therapy and biliary drainage. Results of the treatment of common bile duct stone with either laparoscopic surgery or with the combined endoscopic sphincterotomy plus laparoscopic cholecystectomy are comparable when performed by well-trained practitionners. The choice of the method should be based on the locally available treatment. Copyright © 2011. Published by Elsevier Masson SAS.

    Although biliary lithiasis has been considered a less common pathology in the pediatric population than in adults, in recent years, it has increasingly been diagnosed in children, with a prevalence of between 0.13 to 0.22. The elective treatment of symptomatic biliary lithiasis is cholecystectomy, the laparoscopic approach being considered the œgold standard. We present 3 cases referred to our clinic with biliary lithiasis, in which we performed laparoscopic cholecystectomy. We performed intraoperative cholangiography with a 4 Fr transcystic catheter. In the first case, the cholangiography showed a dilated CBD, without obstruction. Considering the patient'™s history, with recurrent episodes of choledocal lithiasis, we decided to perform a transcystic drainage. In the second case, cholangiography showed a normal CBD and no obstruction. In the third case cholangiography could not be performed due to technical issues. In all cases we performed retrograde laparoscopic cholecystectomy. The postoperative evolution in all cases was favorable. Studies conducted in the last years showed that laparoscopic cholecystectomy is a safe and efficient approach in the management of symptomatic biliary lithiasis in the paediatric age group. The management of choledocolithiasis is still not well defined: perioperative ERCP with ES, intraoperative cholangiography or intraoperative ultrasound were proposed as options in exploring the biliary tree.

    Since December 1989, 9 patients with inoperable malignant biliary tract obstruction were treated palliatively by a combined modality treatment consisting of placement of a permanent biliary endoprosthesis followed by intraluminal high dose-rate [sup 192]Ir brachytherapy. A dose of 10 Gy was delivered in a hyperfractionated schedule at the point of reference in a distance of 7.5 mm of centre of the source. External small field radiotherapy (50.4 Gy, 1.8 Gy per day, 5 fractions per week) was also given in six cases (M/O, Karnofsky >60%). In 9/9 cases an unrestrained bile flow and an interruption of pruritus was achieved, in 78% (7/9) of cases the duration of palliation was as long as the survival time (median survival time 7.5 months).

    A novel lumen-apposing, self-expanding metal stent to perform EUS-guided drainage procedures has been recently developed. The aim of this study was to analyze the safety, technical and clinical effectiveness of this device for EUS-guided choledochoduodenostomy (EUS-CD) with palliative intent. Retrospective analysis of all consecutive patients with unresectable malignant distal bile duct obstruction who, between March 2012 and September 2014, underwent EUS-CD using the study devices (AXIOS™ and Hot AXIOS™, Xlumena Inc., Mountain View, CA, USA) after unsuccessful ERCP in seven European centers was carried out. Fifty-seven patients (M/F 31/26; median age 73) underwent EUS-CD using the AXIOS™ stent or the Hot AXIOS™ delivery system. ERCP failure was due to duodenal obstruction in 41 patients (71.9 %) and to inability to cannulate the papilla in the remaining 16 patients (28.1 %). The procedure was technically successful in 56/57 patients (98.2 %), with a mean procedural time of 22.4 min (range 11-65). Clinical success was achieved in 54 of these 56 patients (96.4 %; 94.7 % of the entire cohort). Overall major procedural complication rate was 7 % (two duodenal perforations, one bleeding and one transient cholangitis). During follow-up, 5 out of 54 (9.3 %) patients with clinica success required re-intervention for stent migration in one case and a sump syndrome with transient increase in serum bilirubin concentrations with sludge in the distal duct reservoir in the remaining four patients. Our study shows that EUS-CD using the AXIOS™ and the Hot AXIOS™ devices is a safe procedure, with high technical and clinical success rates.

    We report a rare cause of biliary cast secondary to cholangitis and pancreatitis, in a 60 year old female patient with pancreas divisum. She was admitted in our hospital with an acute pancreatitis (alcoholic etiology was excluded) complicated with pancreatic abscess and obstructive jaundice. The patient had undergone a complex surgical intervention: cholecystectomy,choledocotomy with extraction of the biliary thrombus,external biliary drainage through a T tube, evacuation of the pancreatic abscess, sequestrectomy, peritoneal lavage and multipledrainages. In spite of the surgical and intensive care support,the biliary drainage through the T tube had ceased and the obstructive jaundice had reappeared in a more accentuated fashion. Endoscopic retrograde cholangiography showed complete pancreas divisum and diffuse multiple stenosis alternating with dilatation of the intrahepatic biliary tree (a pattern of sclerosing cholangitis). An endoscopic prosthesis was placed inside the right hepatic bile duct. Despite the use of the combined endoscopic plus UDCA (ursodeoxycholic acid) treatment for the management of the biliary cast syndrome, the evolution was unfavorable with hepatic coma,septic shock and finally death. The necropsy revealed an extensive biliary cast in the entire biliary tree and pyogeniccholangitis. The patient had a fatal outcome despite all the surgical, endoscopic and conservative efforts, with development of intraductal biliary obstruction and secondary pyogenic cholangitis. Biliary cast syndrome is a rare but very aggressive entity and its management is often difficult despite the advances in surgery and endoscopy treatments. Celsius.

    Full Text Available 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.

    Percutaneous transhepatic biliary drainage is a safe, effective and palliative means of treatment in biliary obstruction, especially in cases with malignant obstruction which are inoperable. 175 cases of transhepatic biliary drainage were performed on 119 patients with biliary obstruction from January 1985 to June 1989 at Kyung-pook National University Hospital. The causes of obstructive jaundice were 110 malignant diseases and 9 benign diseases. The most common indication for drainage was palliative intervention of obstruction secondary to malignant tumor in 89 cases. 86 cases of external drainage were performed including 3 cases of left duct approach, 29 cases of external-internal drainage and 60 cases of endoprosthesis. In external and external-internal drainages, immediate major complications (11.9%) occurred, including not restricted to, but sepsis, bile peritonitis and hemobilia. Delayed major complications (42.9%) were mainly catheter related. The delayed major complication of endoprosthesis resulted from obstruction of the internal stent. The mean time period to reobstruction of the internal stent was about 12 weeks. To improve management status, regular follow-up is required, as is education of both patients and their families as to when immediate clinical attention is mandated. Close communication amongst the varying medical specialities involved will be necessary to provide optional treatment for each patient.

    Metastasis of colon adenocarcinoma is commonly found in the lung, liver, or peritoneum. Common bile duct (CBD) tumors related to adenomas from familial adenomatous polyposis metastasizing from outside of the gastrointestinal tract have been reported. We report a case of biliary colic due to metastatic colon adenocarcinoma to the CBD. Obstructive jaundice with signs of acalculous cholecystitis on imaging in a patient with a history of colon cancer should raise suspicion for metastasis to CBD.

    Endoscopic biliary drainage is an established mode of treatment for acute cholangitis. We compared the safety and efficacy of nasobiliary drain (NBD) placement and stent placement for biliary drainage in patients with acute cholangitis. We recruited a total of 150 patients with severe cholangitis who required endoscopic biliary drainage. Patients were randomized to have either a 7-Fr NBD or a 7-Fr straight flap stent placed during endoscopy. Outcome measures included complications related to endoscopic retrograde cholangiopancreatography (ERCP) and the clinical outcome. Of the 150 patients, 75 were randomized to the NBD group and 75 to the stent group. The most common causes of biliary obstruction were common bile duct stones (n = 102) and biliopancreatic malignancies (n = 37). The site of the biliary obstruction was predominantly found to be the lower part of common bile duct in both the NBD group (n = 58) and the stent group (n = 59). Indications for biliary drainage were: a fever of > 100.4 degrees F (n = 140), hypotension (n = 23), peritonism (n = 40), impaired consciousness (n = 29), and failure to improve with conservative management (n = 45). Biliary drainage was achieved in 147 patients. Abdominal pain, fever, jaundice, hypotension, peritonism and altered sensorium improved after a median period of 2 days in both groups. Leukocyte counts became normal after a median time of 7 days in the NBD group and 6 days in the stent group. There were no ERCP-related complications. There were no instances of displacement or kinking of an NBD, occlusion of an NBD or stent, or of stent migration. Four patients died (two in the NBD group and two in the stent group) as a result of uncontrolled cholangitis after 1, 2, 4, and 6 days of biliary drainage. The success rates of biliary drainage in cholangitis were not affected by the type of endoprosthesis used (72/74 for NBD patients vs. 71/73 for stent patients), the etiology of the biliary obstruction (110/112 for benign

    To define the role of harmonic imaging in the study of biliary lithiasis. We included 50 consecutive patients with suspected biliary lithiasis. Three independent observers compared results of harmonic imaging and conventional ultrasonography. This study showed a better interobserver agreement with harmonic imaging for acoustic shadow (kappa=0.87 vs 0.68) and intra-hepatic biliary stones (kappa=0.79 vs 0.49). More stones and more lithiasic gallbladders were seen with harmonic imaging (27 vs 24) and visualization of gallbladder sludge and the acoustic shadow from stones (P=0.01) was better. Ultrasound examination appears to be easier and faster and the diagnosis is more certain with harmonic imaging than with conventional ultrasonography (P=0.005). Harmonic imaging provides more information on biliary lithiasis and a more certain diagnosis.

    Full Text Available Chronic non-suppurative destructive cholangitis, the so-called primary biliary cirrhosis, is characterised by changes, which occur in intrahepatic bile ducts in early stages and in hepatic parenchyma as the disease progresses. The disease gradually evolves into the full-blown picture of biliary cirrhosis. Primary biliary cirrhosis predominantly affects women between 35 and 60 years of age in all social classes and in all races. Our patient was a woman, old 78 years old who admitted for treatment of hypertrophie cardiomyopathy. During the routine laboratory exploration signs of cholestasis were noted: higher values of alkaline phosphatase and gamma glutamyl transferase, combined with low level of platelets, probably of autoimmune origin. Hypercholesterolaemia (7.8 mmol/L associated with normal values of triglycerides was observed. The main criterion for establishing the diagnosis of primary biliary cirrhosis was the titer of antimito-chondrial antibodies in the serum, which was 1:640. At the same time, she had a urinary infection, caused by Escherichia coli, which confirmed possible relationship between primary biliary cirrhosis and occurence of some Gramm negative bacteria, reported elsewhere. On the other hand, biopsy of the liver was just an auxiliary method, serving for the confirmation of diagnosis. Ursodeoxycholic acid was used as the main drug in the therapy of primary biliary cirrhosis. This case of primary biliary cirrhosis is a worth report because of the comorbidity with cardiac symptoms, which were covering symptoms of hepatic disorder.

    Introduction: The Epworth Sleepiness Scale (ESS) is often used in the evaluation of obstructive sleep apnea (OSA), though questions remain about the influence gender, ethnicity, and body morphometry have in the responses to this questionnaire. The aim of this study was to examine differences in ESS scores between various demographic groups of patients referred for polysomnography, and the relationship of these score to sleep-disordered breathing Methods: Nineteen hundred consecutive patients referred for polysomnographic diagnosis of OSA completed questionnaires, including demographic data and ESS. OSA was determined based on a respiratory disturbance index (RDI) ≥15 by polysomnography. Results: In this high risk population for OSA, the ESS was 10.7 ± 5.6. The highest ESS scores were seen in obese males; non-obese females and non-obese Caucasian males scored the lowest. ESS was weakly correlated with RDI (r = 0.17, P < 0.0001). The sensitivity of ESS for the diagnosis of OSA was 54% and the specificity was 57%. The positive (PPV) and negative (NPV) predictive values were 64% and 47%, respectively. In obese subjects, the sensitivity and specificity were 55% and 53%, compared with 47% and 63% in non-obese subjects. In obese, Hispanic males, the sensitivity, specificity, and PPV were 59%, 54%, and 84%, respectively. In non-obese, Caucasian females, the sensitivity, specificity, and NPV were 43%, 59%, and 72%. Conclusions: The ESS appears to be affected by many factors, including gender, ethnicity, and body morphometry. The ability of the ESS to predict OSA is modest, despite a significant correlation with the severity of OSA. The test characteristics improve significantly when applied to select populations, especially those at risk for OSA. PMID:22670164

    Purpose: To evaluate biliary toxicity after stereotactic body radiation therapy (SBRT) for liver tumors. Methods and Materials: Among 297 consecutive patients with liver tumors treated with SBRT of 35 to 50 Gy in 5 fractions, patients who were irradiated with >20 Gy to the central biliary system (CBS), including the gallbladder, and had follow-up times >6 months were retrospectively analyzed. Toxicity profiles, such as clinical symptoms and laboratory and radiologic data especially for obstructive jaundice and biliary infection, were investigated in relation to the dose volume and length relationship for each biliary organ. Results: Fifty patients with 55 tumors were irradiated with >20 Gy to the CBS. The median follow-up period was 18.2 months (range, 6.0-80.5 months). In the dose length analysis, 39, 34, 14, and 2 patients were irradiated with >20 Gy, >30 Gy, >40 Gy, and >50 Gy, respectively, to >1 cm of the biliary tract. Seven patients were irradiated with >20 Gy to >20% of the gallbladder. Only 2 patients experienced asymptomatic bile duct stenosis. One patient, metachronously treated twice with SBRT for tumors adjacent to each other, had a transient increase in hepatic and biliary enzymes 12 months after the second treatment. The high-dose area >80 Gy corresponded to the biliary stenosis region. The other patient experienced biliary stenosis 5 months after SBRT and had no laboratory changes. The biliary tract irradiated with >20 Gy was 7 mm and did not correspond to the bile duct stenosis region. No obstructive jaundice or biliary infection was found in any patient. Conclusions: SBRT for liver tumors adjacent to the CBS was feasible with minimal biliary toxicity. Only 1 patient had exceptional radiation-induced bile duct stenosis. For liver tumors adjacent to the CBS without other effective treatment options, SBRT at a dose of 40 Gy in 5 fractions is a safe treatment with regard to biliary toxicity.

  10. Primary biliary cirrhosis.

    Carey, Elizabeth J; Ali, Ahmad H; Lindor, Keith D

    2015-10-17

    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.

  11. A "nondislodgeable" endoprosthesis for nonsurgical drainage of the biliary tract.

    Silander, T; Thor, K

    1985-01-01

    In patients with obstructive jaundice, biliary decompression can be achieved by an endoprosthesis inserted by a percutaneous transhepatic approach. The prosthesis sometimes becomes dislodged and thus additional percutaneous transhepatic procedures may be required. To avoid this problem, a nondislodgeable endoprosthesis has been developed. The prosthesis is constructed with a layer of biocompatible material (hydrogel) on its surface. The hydrogel is located in grooves around the endoprosthesis and has the ability to absorb liquid, which increases its size. By placing the rings of hydrogel on either side of the obstruction, dislodgement of the prosthesis can be prevented. The nondislodgeable endoprosthesis has been inserted into 11 patients with biliary obstructions due to malignant strictures. No dislodgement has occurred and the established internal drainage reduced serum bilirubin levels without any major complications. Images FIG. 1. FIG. 2. FIG. 4. FIG. 5. FIG. 6. FIG. 7. FIG. 8.

We report a case of BPF following portal vein embolization (PVE in a 79-year-old woman with obstructive jaundice secondary to perihilar cholangiocarcinoma. The patient successfully underwent right-sided PVE; however, the patient developed a symptomatic right-sided bilious pleural effusion the following day. Despite aggressive drainage of the pleural effusion with a large-bore chest tube and maximal medical management, the patient died from respiratory failure and pneumonia. Although rare, knowledge of this complication is important when performing PVE in patients with biliary obstruction because it can be life-threatening. Early recognition and management of this complication are crucial to avoid a poor outcome.

    Full Text Available The scope of this article precludes an ′in depth′ description of all liver problems and I will limit this review to anaesthesia for biliary atresia - a common hepatic problem in the very young - and partial hepatectomy in older children. I will not be discussing the problems of anaesthetising children with hepatitis, cirrhosis, congenital storage diseases or liver failure. Extrahepatic biliary obstruction is an obliterative cholangiopathy of infancy which is fatal if untreated. Diagnosis involves exclusion of other causes of neonatal jaundice and treatment involves a hepatico portoenterostomy carried out at the earliest. This is a review of current concepts in anaesthesia and postoperative management of neonates with extrahepatic biliary atresia. Anaesthesia for hepatic resection has seen great changes in recent times with the improvement in surgical techniques, technology and a better understanding of the underlying physiology. These are reviewed along with the problems of postoperative pain management.

    Gallstones affect about 15% of adults in Europe. Cholesterol gallstone is the common form of the disease. Pigment stones, resulting from bilirubin precipitation feature particular clinical settings such as chronic hemolysis, intestinal malabsorption and various biliary tract diseases. Supersaturation of bile with cholesterol, increased formation of deoxycholic acid and gallbladder hypomotility are the main factors involved in gallstones pathogenesis.

  1. Novel Approach to Bile Duct Damage in Primary Biliary Cirrhosis: Participation of Cellular Senescence and Autophagy

    2012-01-01

    Full Text Available Primary biliary cirrhosis (PBC is characterized by antimitochondrial autoantibodies (AMAs in patients' sera and histologically by chronic nonsuppurative destructive cholangitis in small bile ducts, eventually followed by extensive bile duct loss and biliary cirrhosis. The autoimmune-mediated pathogenesis of bile duct lesions, including the significance of AMAs, triggers of the autoimmune process, and so on remain unclear. We have reported that cellular senescence in biliary epithelial cells (BECs may be involved in bile duct lesions and that autophagy may precede the process of biliary epithelial senescence in PBC. Interestingly, BECs in damaged bile ducts show characteristicsof cellular senescence and autophagy in PBC. A suspected causative factor of biliary epithelial senescence is oxidative stress. Furthermore, senescent BECs may modulate the microenvironment around bile ducts by expressing various chemokines and cytokines called senescence-associated secretory phenotypes and contribute to the pathogenesis in PBC.

    Objective: To evaluate the sensitivity and specificity of magnetic resonance imaging (MR imaging) including MR cholangiography for the identification of cysto-biliary fistulas in patients with hepatic hydatid disease. Patients and methods: Retrospective analysis of 3 groups of patients (20 patients with 51 echinococcal cysts) in a cohort of 103 patients with cystic echinococcosis with different pretest probabilities for cysto-biliary fistulas. Patients who had MR imaging/MR cholangiography with symptoms and signs of biliary obstruction (5 patients with 16 cysts, group I), before surgery for other reasons than biliary obstruction (9 patients with 14 cysts, group II) and for cyst staging (6 patients with 21 cysts, group III). All MR images were evaluated before surgery for the presence of cyst wall defects and hydatid debris in bile ducts. In groups I and II MR results were compared with surgical, parasitological, and biochemical findings of each individual cyst. Results: Based on direct (i.e. defects in the cyst wall and continuity of dilated biliary ducts into adjacent cysts), and indirect MR imaging/MR cholangiography imaging signs (i.e. intraluminal debris) our best estimate of sensitivity and specificity (stage-specific, WHO type CE3 and CE4) for cysto-biliary fistulas was 75% and 95%, respectively. Conclusions: MR imaging with MR cholangiography is a valuable non-invasive imaging technique to assess the risk of cysto-biliary fistula-related complications and for planning of surgery.

  3. Sclerosing Cholangitis and Primary Biliary Cirrhosis—a Disease Spectrum?

    1977-01-01

    Sclerosing diseases of the biliary system encompass a spectrum ranging from primary sclerosing cholangitis (usually of the extrahepatic biliary tree) to primary biliary cirrhosis of the intrahepatic bile canaliculi. In a study of 35 patients with primary intra- and extrahepatic biliary sclerosis, age of onset, sex distribution, symptomatology, associated diseases, radiographic abnormalities and chemical profile were considered. The difficulty of differentiating sclerosing cholangitis and biliary cirrhosis from other causes of obstructive jaundice preoperatively was stressed, in addition to points of differential clinical and laboratory findings. The etiology of these entities as well as the possibility that they represent variant clinical manifestations of the same disease process were also considered. Mechanical and pharmacological treatment alternatives that were attempted included drainage procedures, the easiest and most widely used of which was the T-tube. However, this could prove to be a source of infection and should therefore be removed early, inasmuch as cholangitis represents a major cause of morbidity. Steroids have been used with varying effectiveness; subjective improvement was generally attained, although objective improvement has been difficult to document. When choleuretics and cholestyramine were administered, we noted significant palliation. Antibiotics were reserved for treatment of cholangitis. Until the underlying etiology of this rare malignant sclerosing process is found, only symptomatic treatment can be offered. PMID:921353

    Full Text Available PURPOSE: To study the influence of glutamine on functional and morphological changes of liver in the extrahepatic biliary obstruction through an experimental model in rats. METHODS: Seventy Wistar rats were divided into four groups: control (group C fictitious operation, (group FO, submitted to laparotomy with handling of bile ducts, but without hepatic duct ligation, (group EBO submitted to laparotomy and hepatic duct ligation, one of them submitted to supplementation with glutamine 2% (group G. The control group consisted of 6 animals. The animals from groups FO, EBO and G were divided into three groups consisting of 6 animals each, being sacrificed at 7, 14 and 21 days after operation, respectively. Blood samples were collected for biochemical analysis and a fragment of liver tissue was collected from the middle lobe for histological analysis. RESULTS: Both for biochemical analysis (BT, aspartate and alanine aminotransferase AST, ALT and alkaline phosphatase FAL and for histopathological changes (fibrosis, portal inflammation, parenchymal inflammation, hepatocytic changes and duct proliferation, no statistical difference between groups submitted to extrahepatic biliary obstruction (EBO with and without treatment with glutamine (G was observed. CONCLUSION: Glutamine supplementation did not alter the prognosis of liver enzymes and histopathological changes in animals submitted to extrahepatic biliary obstruction.OBJETIVO: Estudar a influência da glutamina em alterações funcionais e morfológicas do fígado na obstrução biliar extra-hepática por meio de um modelo experimental desenvolvido em ratos.

    The term, portal biliopathy, denotes various biliary abnormalities, such as stenosis and/or dilatation of the bile duct, in patients with portal hypertension. These vascular abnormalities sometimes bring on an obstructive jaundice, but they are not clear which vessels participated in obstructive jaundice. The aim of present study was clear the bile ductal changes in patients with portal hypertension in hopes of establishing a therapeutic strategy for obstructive jaundice caused by biliary varices. Three hundred and thirty-seven patients who underwent intraductal ultrasound (IDUS) during endoscopic retrograde cholangiography for biliary abnormalities were enrolled. Portal biliopathy was analyzed using IDUS. Biliary varices were identified in 11 (2.7%) patients. IDUS revealed biliary varices as multiple, hypoechoic features surrounding the bile duct wall. These varices could be categorized into one of two groups according to their location in the sectional image of bile duct: epicholedochal and paracholedochal. Epicholedochal varices were identified in all patients, but paracholedochal varices were observed only in patients with extrahepatic portal obstruction. IDUS was useful to characterize the anatomy of portal biliopathy in detail.

    Hepatobiliary ultrasound was carried out on 2224 consecutive patients at the Center for Nuclear Medicine and Ultrasound and at one private diagnostic center in Mymensingh for ultrasound examination of different systems. The purpose of this study was to investigate the prevalence of biliary ascariasis and its association with other biliary diseases, specially biliary lithiasis. Data regarding the presence of stone, worm or other diseases were recorded accordingly in this prospective study. There were 952 male and 1272 female patients with an age range of 5-90 years. Biliary diseases were detected in 305 patients (13.71%), of whom 97 were male (10.19%) and 208 were female (16.35%). The most common biliary disease in both sexes was cholelithiasis (11.87%), which was found in 84 male patients (8.82%) and in 180 female patients (14.15%). Other diseases found were choledocholithiasis in 14 patients (3 males, 11 females), gall bladder mass in 9 patients (3 males, 6 females), common bile duct mass in 7 patients (4 male, 3 female) and biliary ascariasis in 10 patients (3 male, 7 female). Overall prevalence of biliary ascariasis was 0.45% (0.31% in male patients and 0.55% in female patients), and age range of patients with the condition was 6-50 years. No case of biliary ascariasis was associated with cholelithiasis or choledocholithiasis. Acute cholecystitis was associated with 8 cases (80%) of biliary ascariasis. Common sonographic findings in patients with biliary ascariasis were a single long, linear or curved echogenic structure within the bile duct, without acoustic shadowing. Other findings were gall bladder distention with sludge inside, an edematous wall and mildly dilated biliary tree. Prevalence of biliary ascariasis in the study was 0.45%, with incidence being higher in female subjects (0.55%). No correlation was found between biliary ascariasis and biliary lithiasis. Most of the cases of biliary ascariasis were associated with acute cholecystitis. We concluded

    Percutaneous biliary drainage is an important technique for palliative therapy of obstructive biliary disease and diagnostic information. The purpose of this study is to review and evaluate the experiences of ultrasound-guided percutaneous transhepatic biliary drainage. Ultrasound-guided percutaneous transhepatic biliary drainage was performed on 146 occasions in 134 patients. The causes of biliary obstruction were: benign diseases (19 cases, 14.2%) such as bile duct stones or stricture, cholangiocarcinoma (37 cases, 27.6%), pancreatic carcinoma (35 cases, 26.1%), metastasis (22 cases, 16.5%), gall bladder cancer (14 cases, 10.4%), ampulla of Vater cancer (4 cases, 3.0%), hepatocellular carcinoma (3 cases, 2.2%). Retrospectively reviewing medical records, we found out frequency of external or external/internal biliary drainages, puncture of left or right hepatic duct, and presence of bileinfection. Ultrasound-guided percutaneous transhepatic biliary drainage was compared with conventional biliary drainage of previous reports on the basis of frequency of complications. External (124 procedures, 84.9%) and external/internal biliary drainage (22 procedures, 15.1%) were carried out by puncture of dilated right (59.6%) or left (40.4%) intrahepatic duct. Sixty-nine complications occurred in 47 patients. Catheter related complications (33/69, 47.8%) were most common: catheter dislodgement (17/69, 24.6%), malfunction (9/69, 13.1%), leakage (7/69, 10.1%). Other minor complications such as simple fever (16/69, 23.2%), cholangitis (7/69, 10.1%), hemobilia (4/69, 5.8%), biloma (2/69, 2.9%) and wound infection (1/69, 1.5%) occurred. Major complications including sepsis (4/69, 5.8%) and bile peritonitis (2/69, 2.9%) were also noted. Puncture-related complications such as hemobilia, biloma and bile peritonitis occurred in 8 cases (5.5%). Comparing with conventional X-ray guided drainage, ultrasound-guided percutaneous transhepatic biliary drainage is a safe procedure for

    Patients suspected of having acute cholecystitis can present a difficult diagnostic problem. Cholescintigraphy using {sup 99m}Tc-labeled analogues of imino-diacetic acid (IDA) is a sensitive and specific test for the early diagnosis of acute cholecystitis. The radiopharmaceutical enters the bilirubin metabolic pathway and follows the hepatic bile flow. A cystic duct obstruction is suspected if the gall-bladder does not take up the tracer 40 to 60 min after the injection, provided that the radiotracer is seen the small intestine. At that moment, morphine sulfate can be given intravenously. Acute cholecystitis is deemed present if the gall-bladder is still unseen 30 min after morphine injection or 4 hours after the radiotracer administration if morphine is contraindicated. Cholescintigraphy proves also useful in diagnosing post-surgical or post-traumatic biliary injuries. This test conveys complementary information to ultrasonography and computed tomography in cases of bile leakage, collected or free in the peritoneal cavity, in confirming the biliary origin of the collection.

    Background: Endoscopic evaluation is critical in assessing the cause of obstructive jaundice. Cytological techniques including bile aspiration and biliary brushings have become the initial diagnostic modality. Aim: The aim of this study is to evaluate the role of endoscopic biliary tract cytology as a diagnostic tool in the evaluation of extrahepatic cholestatic jaundice. Materials and Methods: A total of 56 biliary tract specimens including 34 bile aspirations and 22 biliary brushings from 41 consecutive patients who had presented with obstructive jaundice and underwent endoscopic retrograde cholangiopancreatography (ERCP) were assessed by cytological examination. The smears prepared were analyzed for standard cytological features. Results: Cytologic diagnosis was adenocarcinoma in 13 (31.7%) cases, atypical in 2 (4.9%), reactive in 3 (7.3%) and benign changes in 19 (46.3%) cases. 4 (9.8%) cases were non-diagnostic. Serum bilirubin was significantly elevated in the malignant group. Biliary stricture was the most common finding on ERCP (68.3%). On cytological examination, presence of solitary, intact atypical cells, enlarged nuclei, irregular nuclear membrane, coarse chromatin and nucleoli were important cytologic criteria for differentiating malignant from benign biliary specimens. Conclusions: Regular use of bile cytology and brushings during ERCP evaluation of extrahepatic cholestatic jaundice is invaluable in obtaining a morphologic diagnosis. A systematic approach, use of strict cytomorphologic criteria and inclusion of significant atypia as malignant diagnosis may improve the sensitivity. PMID:24130407

    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.

    Abstract This report describes the novel sampling of bile from the biliary endoscopic intervention for the molecular identification of parasite infection. A 63-year-old Vietnamese man underwent travel health examination in our hospital. Physical examination showed that his height was 159 cm and weight was 41 kg. He had a 15-year history of intermittent abdominal pain and frequent episodes of diarrhea. Laboratory tests revealed raised eosinophil count (23%, normal range [NR] 0–5), absolute eosinophil count (1899/μL, NR 50–350), and levels of serum immunoglobulin E (3770 IU/mL, NR Isospora belli (IB) infection was identified by a polymerase chain reaction. Trimethoprim–sulfamethoxazole 800 mg q6h was administered for 1 month. Liver enzyme levels normalized and negative for concentration method of ova study. The patient was doing well and weighed 51 kg at the outpatient clinic visit 3 months later. This bile sampling with molecular identification has not been described in the literature. We believe that an acute IB infection through fecal-oral transmission may progress to chronic infection of the hepatobiliary system, leading to biliary obstruction and jaundice. PMID:26962840

Although endoscopic retrograde cholangiopancreatography (ERCP) with stent placement is the current gold standard for biliary decompression, it can sometimes be difficult because of failed biliary cannulation. In this retrospective case series, we describe three cases of successful biliary drainage with recovery from septic shock after urgent endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) was performed for AOSC due to biliary lithiasis. In all three cases, technical success in inserting the stents was achieved and the patients completely recovered from AOSC with sepsis in a few days after EUS-CDS. There were no procedure-related complications. When initial ERCP fails, EUS-CDS can be an effective life-saving endoscopic biliary decompression procedure that shortens the procedure time and prevents post-ERCP pancreatitis, particularly in patients with AOSC-induced sepsis.

    Full Text Available Biliary innate immunity is involved in the pathogenesis of cholangiopathies in cases of biliary disease. Cholangiocytes possess Toll-like receptors (TLRs which recognize pathogen-associated molecular patterns (PAMPs and play a pivotal role in the innate immune response. Tolerance to bacterial PAMPs such as lipopolysaccharides is also important to maintain homeostasis in the biliary tree, but tolerance to double-stranded RNA (dsRNA is not found. Moreover, in primary biliary cirrhosis (PBC and biliary atresia, biliary innate immunity is closely associated with the dysregulation of the periductal cytokine milieu and the induction of biliary apoptosis and epithelial-mesenchymal transition (EMT, forming in disease-specific cholangiopathy. Biliary innate immunity is associated with the pathogenesis of various cholangiopathies in biliary diseases as well as biliary defense systems.

    Full Text Available PURPOSE: To evaluate liver alterations caused by biliary obstruction and drainage. METHODS: Thirty-nine male Wistar rats were randomly distributed in 4 groups: BO (n=18 bile duct ligation for 20 days, with a periodic evaluation of liver histological alterations, Doppler echography portal flow and measurements of NO and malondialdehyde (MDA; BO/DB (n=13 bile duct occlusion for 20 days followed by biliary drainage by choledochoduodenal anastomosis, 5 days follow-up, same BO group parameters evaluations; group CED (n=4 sham operation and portal flow evaluation trough 20 days; CHB (n=4 sham operation, with hepatic biopsy on 25th day and followed-up trough 25 days, by the same parameters of group BO, with exception of portal flow. Direct bilirubin (DB and alkaline phosphatase (AP were evaluated in the group BO, BO/DB and CHB. RESULTS: The bile duct ligation led to an increase of DB and AP, development of liver histological alterations, reduction of portal flow and increase of plasmatic NO and of MDA levels. The bile duct clearing resulted in a reduction of DB, AP, NO, MDA histological alterations and increase of portal flow. CONCLUSION: The biliary occlusion resulted in cholestasis and portal flow reduction, besides the increase of plasmatic NO and of hepatic MDA levels, and histological liver alterations, with a tendency of normalization after the bile duct clearing.OBJETIVO: Avaliar alterações hepáticas resultantes do processo de obstrução/desobstrução biliar.

    Laparoscopic techniques are evolving for a wide range of surgical procedures although they were initially confined to cholecystectomy and exploratory laparoscopy. Recently, surgical procedures performed with a laparoscope include splenectomy, adrenalectomy, gastrectomy, and myomectomy. In this article, we review the spectrum of complications and illustrate imaging features of biliary and nonbiliary complications after various laparoscopic surgeries. Biliary complications following laparoscopic cholecystectomy include bile ductal obstruction, bile leak with bile duct injury, dropped stones in the peritoneal cavity, retained CBD stone, and port-site metastasis. Nonbiliary complications are anastomotic leakage after partial gastrectomy, gangrenous cholecystitis after gastrectomy, hematoma at the anastomotic site following gastrectomy, gastric infarction after gastrectomy, port-site metastasis after gastrectomy, hematoma after splenectomy, renal infarction after adrenalectomy, and active bleeding after myomectomy of the uterus.

    The value of biliary endoscopy was determined in 100 consecutive patients undergoing choledochotomy. Using a compact, rigid, right-angled choledochoscope with a rod-lens optical system the biliary tract was inspected for residual stomes following conventional exploration. Completion operative cholangiography and postoperative T-tube cholangiography were performed in all patients. Of 52 patients undergoing primary choledocholithotomy, the duct was cleared of all calculi in 51. A small residual stone was found by postoperative cholangiography in one patient. Exploration revealed no calculi in the ducts of the remaining 30 patients. Biliary endoscopy was of benefit to the surgeon in the majority of patients. In 17 patients, calculi missed by standard exploration were detected; in five of these, the calculi could be retrieved only under endoscopic control. In 11 patients, interpretation of operative cholangiograms was aided, while in three the endoscopic findings clarified operative strategy. The use of biliary endoscopy did not increase the postoperative morbidity or mortality rates beyond those oridinarily encountered in choledocholithotomy. Current experience indicates that the new choledhchoscope overcomes limitations of previous endoscopes and should serve as the definitive diagnostic tool for operative biliary endoscopy. The addition of this technique to the armamentarium of the biliary surgeon will play a significant role in overcoming the age-old problem of the retained common duct stone.

    Full Text Available Abstract 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

    Objective: Evaluate experience over 15 years with treatment of this lesion. Summary Background Data: Biliary cystadenoma, a benign hepatic tumor arising from Von Meyenberg complexes, usually present as septated intrahepatic cystic lesions. Methods: Data were collected concurrently and retrospectively on patients identified from hospital medical records reviewed for pertinent International Classification of Diseases, Ninth Revision, Clinical Modification and CPT codes, pathology logs, and from operative case logs. Pathology specimens were rereviewed to confirm the diagnosis of biliary cystadenoma or biliary cystadenocarcinoma by 2 GI pathologists. Results: From October 1989 to April 2004 at our institution, 19 (18F:1M) patients had pathologically confirmed biliary cystadenomas, including one with a biliary cystadenocarcinoma. The mean age was 48 ± 15 years at initial evaluation. Complaints included abdominal pain in 74%, abdominal distension in 26%, and nausea/vomiting in 11%. Only 1 patient presented with an incidental finding. Symptoms had been present for 3 ± 5 years, with 1 to 4 different surgeons and many other physicians involved in the diagnosis or treatment prior to definitive ablation. Eight patients had undergone 20 previous treatments, including multiple percutaneous aspirations in 4 and 11 operative procedures. CT or US was diagnostic in 95%, with internal septations present in the hepatic cysts. Definitive operative intervention consisted of hepatic resection in 12 patients, enucleation in 6 patients, and fenestration and complete fulguration in 1 patient. There were no perioperative deaths. No recurrences were observed after definitive therapy, with follow-up of 4 ± 4 years. Conclusions: Biliary cystadenoma must be recognized and treated differently than most hepatic cysts. There remains a need for education about the imaging findings for biliary cystadenoma to reduce the demonstrated delay in appropriate treatment. Traditional treatment of simple

    Endoscopic retrograde cholangiopancreatography had been a treatment modality of choice for both benign and malignant biliary tract obstruction for more than half century, with a very high clinical success rate and low complications. But in certain circumstances, such as advanced and locally advanced pancreatobiliary malignancies (pancreatic cancer, cholangiocarcinoma, ampullary tumor) and tight benign strictures, endoscopic retrograde cholangiopancreatography (ERCP) fails. Up to this point, the only alternative interventions for these conditions were percutaneous transhepatic biliary drainage or surgery. Endoscopic ultrasound guided interventions was introduced for a couple decades with the better visualization and achievement of the pancreatobiliary tract. And it's still in the process of ongoing development. The inventions of new techniques and accessories lead to more feasibility of high-ended procedures. Endoscopic ultrasound guided biliary drainage was a novel treatment modality for the patient who failed ERCP with the less invasive technique comparing to surgical bypass. The technical and clinical success was high with acceptable complications. Regarded the ability to drain the biliary tract internally without an exploratory laparotomy, this treatment modality became a very interesting procedures for many endosonographers, worldwide, in a short period. We have reviewed the literature and suggest that endoscopic ultrasound-guided biliary drainage is also an option, and one with a high probability of success, for biliary drainage in the patients who failed conventional endoscopic drainage.

  11. Hepatic and biliary ascariasis

    Full Text Available Ascariasis mainly contributes to the global helminthic burden by infesting a large number of children in the tropical countries. Hepato-biliary ascariasis (HBA is becoming a common entity now than in the past owing to the frequent usage of ultrasonograms and endoscopic diagnostic procedures in the clinical practice. There are a variety of manifestations in HBA and diagnosis depends on a high index of suspicion in endemic areas coupled with subsequent confirmation by sonographic or endoscopic demonstration of the worm. Most of them present with acute abdomen and jaundice. Oriental or recurrent pyogenic cholangiopathy is possibly the result of HBA, commonly encountered in South-East Asian countries. Conservative treatment with anthelminthic agents is used in the majority. Failure to respond to medical therapy usually indicates the need for endoscopic or surgical interventions. Overall, mortality is low and prognosis is good, but many epidemiological and immunological aspects of Ascaris infection are unclear, meaning our understanding the disease and infection still remains incomplete. Therefore, it is difficult to definitely put down a fixed modality of treatment for HBA. This underscores the need for further studies as ascariasis has the potential to adversely affect the national socio-economy by compromising the health of children and adults alike with its sheer number.

    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.

    Langerhans' cell histiocytosis (LCH) is a disease of unknown pathogenesis, caused by clonal proliferation of Langerhans' cells. Liver involvement results in a cholangiopathy, which has the radiologic appearance of sclerosing cholangitis. Only 1 case of obstructive jaundice due to common bile duct stone in a patient with LCH has been described. We present a case of a 31-month-old child with LCH and liver involvement on the waiting list for liver transplantation. During the follow-up, there was a rapid onset of jaundice due to sludge and lithiasis. The patient was treated first with an endoscopic biliary plastic stent and then with percutaneous biliary drainage and bilioenteric anastomosis.

    The advantages of endoscopic retrograde cholangiopancreatography over open surgery have made it the predominant method of treating patients with choledocholithiasis. After sphincterotomy, however, 10%-15% of common bile duct stones cannot be removed with a basket or balloon. The methods for managing "irretrievable stones" include surgery, mechanical lithotripsy, intraductal or extracorporeal shock wave lithotripsy and biliary stenting. The case presented was a referred 82-year-old Caucasian woman with a 7-year-old plastic biliary endoprosthesis in situ. To the best of our knowledge the examined endoprosthesis is the oldest endoprosthesis in situ reported in the literature. Endoscopic biliary endoprosthesis placement remains a simple and safe procedure for patients with stones that are difficult to manage by conventional endoscopic methods and for patients who are unfit for surgery or who are high surgical risks. To date no consensus has been reached regarding how long a biliary prosthesis should remain in situ. Long-term biliary stenting may have a role in selected elderly patients if stones extraction has failed because the procedure may prevent stones impaction and cholangitis.

    Full Text Available Mechanic intestinal obstruction, caused by the passage of biliary calculus from vesicle to intestine, through fistulization, although not frequent, deserve study due to the morbi-mortality rates. Incidence in elder people explains the association with chronic degenerative diseases, increasing complexity in terms of therapy decision. Literature discusses the need and opportunity for the one or two-phase surgical attack of the cholecystenteric fistule, in front of the resolution on the obstructive urgency and makes reference to Gallstone Ileus as an exception for strong intestinal obstruction. The more frequent intestinal obstruction observed is when it occurs a Gallstone Ileus impacting in terms of ileocecal valve. The authors submit a Gallstone Ileus manifestation as causing strong intestinal obstruction, discussing aspects regarding diagnostic and treatment.

  19. Biliary Stricture Following Hepatic Resection

    Directory of Open Access Journals (Sweden)

    Jeffrey B. Matthews

    1991-01-01

    Full Text Available Anatomic distortion and displacement of hilar structures due to liver lobe atrophy and hypertrophy occasionally complicates the surgical approach for biliary stricture repair. Benign biliary stricture following hepatic resection deserves special consideration in this regard because the inevitable hypertrophy of the residual liver causes marked rotation and displacement of the hepatic hilum that if not anticipated may render exposure for repair difficult and dangerous. Three patients with biliary stricture after hepatectomy illustrate the influence of hepatic regeneration on attempts at subsequent stricture repair. Following left hepatectomy, hypertrophy of the right and caudate lobes causes an anteromedial rotation and displacement of the portal structures. After right hepatectomy, the rotation is posterolateral, and a thoracoabdominal approach may be necessary for adequate exposure. Radiographs obtained in the standard anteroposterior projection may be deceptive, and lateral views are recommended to aid in operative planning.

    Kumagi, Teru; Heathcote, E Jenny

    2008-01-01

    Primary biliary cirrhosis (PBC) is a chronic and slowly progressive cholestatic liver disease of autoimmune etiology characterized by injury of the intrahepatic bile ducts that may eventually lead to liver failure. Affected individuals are usually in their fifth to seventh decades of life at time of diagnosis, and 90% are women. Annual incidence is estimated between 0.7 and 49 cases per million-population and prevalence between 6.7 and 940 cases per million-population (depending on age and sex). The majority of patients are asymptomatic at diagnosis, however, some patients present with symptoms of fatigue and/or pruritus. Patients may even present with ascites, hepatic encephalopathy and/or esophageal variceal hemorrhage. PBC is associated with other autoimmune diseases such as Sjogren's syndrome, scleroderma, Raynaud's phenomenon and CREST syndrome and is regarded as an organ specific autoimmune disease. Genetic susceptibility as a predisposing factor for PBC has been suggested. Environmental factors may have potential causative role (infection, chemicals, smoking). Diagnosis is based on a combination of clinical features, abnormal liver biochemical pattern in a cholestatic picture persisting for more than six months and presence of detectable antimitochondrial antibodies (AMA) in serum. All AMA negative patients with cholestatic liver disease should be carefully evaluated with cholangiography and liver biopsy. Ursodeoxycholic acid (UDCA) is the only currently known medication that can slow the disease progression. Patients, particularly those who start UDCA treatment at early-stage disease and who respond in terms of improvement of the liver biochemistry, have a good prognosis. Liver transplantation is usually an option for patients with liver failure and the outcome is 70% survival at 7 years. Recently, animal models have been discovered that may provide a new insight into the pathogenesis of this disease and facilitate appreciation for novel treatment in PBC

    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.

Biliary epithelial cells possess an innate immune system consisting of the Toll-like receptor (TLR family and recognize pathogen-associated molecular patterns (PAMPs. Tolerance to bacterial PAMPs such as lipopolysaccharides is also important to maintain homeostasis in the biliary tree, but tolerance to double-stranded RNA (dsRNA is not found. In PBC, CD4-positive Th17 cells characterized by the secretion of IL-17 are implicated in the chronic inflammation of bile ducts and the presence of Th17 cells around bile ducts is causally associated with the biliary innate immune responses to PAMPs. Moreover, a negative regulator of intracellular TLR signaling, peroxisome proliferator-activated receptor-γ (PPARγ, is involved in the pathogenesis of cholangitis. Immunosuppression using PPARγ ligands may help to attenuate the bile duct damage in PBC patients. In biliary atresia characterized by a progressive, inflammatory, and sclerosing cholangiopathy, dsRNA viruses are speculated to be an etiological agent and to directly induce enhanced biliary apoptosis via the expression of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL. Moreover, the epithelial-mesenchymal transition (EMT of biliary epithelial cells is also evoked by the biliary innate immune response to dsRNA.

    Obstructive azoospermia represents approximately 10 % of cases of male hypofertility. It is classified according to the volume of ejaculate. When the latter is normal a proximal obstruction is suspected. Scrotal sonography can help to detect dilation of the epididymal head when clinical findings are equivocal. Ejaculatory duct obstruction (EDO) is suspected when the volume of ejaculate is low. The use of transrectal ultrasonography (TRUS) plays a major role in the investigation of these patients, and endorectal MRI is a very useful adjunct in selected cases. The most common cause of EDO is congenital bilateral absence of vas deferens, which is now thought to be a genital form of cystic fibrosis in 80 % of cases. Consequently, a definitive diagnosis must be made before any attempt at in vitro fertilization. TRUS accurately visualizes abnormalities of the caudal junction of the vas deferens and seminal vesicles, yielding a definitive diagnosis without scrototomy. Other causes of EDO are congenital cysts compressing the distal part of the ejaculatory ducts and inflammatory distal stenosis. The former are accurately identified by TRUS, but the latter give more or less marked signs of obstruction which are only of value in azoospermic patients with a low-volume ejaculate. More invasive imaging is required to diagnose partial obstruction of the ED. Surgical vasography is still the reference, but puncture of the seminal vesicles under TRUS guidance is an attractive alternative, as it permits aspiration of seminal fluid (to seek motile sperm) and vasography without scrototomy. Lastly, endorectal MRI well assesses the relationships between the proximal prostatic urethra and the posterior wall of the ejaculatory ducts, which need to be precisely known when endoscopic resection of the ejaculatory ducts is planned.

    2010-01-01

    Full Text Available Primary biliary cirrhosis (PBC is a chronic cholestatic liver disease characterized serologically by the high prevalence of anti-mitochondrial autoantibodies (AMAs and histologically by the cholangitis of small bile ducts, eventually followed by extensive loss of the small bile duct. An autoimmune pathogenesis is suggested by clinical and experimental studies, but there remain issues regarding the etiology, the significance of AMAs in the pathogenesis of bile duct lesions, and so on. The unique properties of apoptosis in biliary epithelial cells (BECs, in which there is exposure of autoantigen to the effectors of the immune system, are proposed to be a cause of bile duct lesions in PBC. Recent progress disclosed that cellular senescence and autophagy are involved in bile duct lesions in PBC. Senescent BECs may modulate the periductal microenvironment by expressing senescence-associated secretory phenotypes, including various chemokines, and contribute to the pathogenesis of bile duct lesions in PBC.

  11. Postoperative biliary adverse events following orthotopic liver transplantation: assessment with magnetic resonance cholangiography.

    Biliary adverse events following orthotopic liver transplantation (OLT) are relatively common and continue to be serious causes of morbidity, mortality, and transplant dysfunction or failure. The development of these adverse events is heavily influenced by the type of anastomosis during surgery. The low specificity of clinical and biologic findings makes the diagnosis challenging. Moreover, direct cholangiographic procedures such as endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography present an inadmissible rate of adverse events to be utilized in clinically low suspected patients. Magnetic resonance (MR) maging with MR cholangiopancreatography is crucial in assessing abnormalities in the biliary system after liver surgery, including liver transplant. MR cholangiopancreatography is a safe, rapid, non-invasive, and effective diagnostic procedure for the evaluation of biliary adverse events after liver transplantation, since it plays an increasingly important role in the diagnosis and management of these events. On the basis of a recent systematic review of the literature the summary estimates of sensitivity and specificity of MR cholangiopancreatography for diagnosis of biliary adverse events following OLT were 0.95 and 0.92, respectively. It can provide a non-invasive method of imaging surgical reconstruction of the biliary anastomoses as well as adverse events including anastomotic and non-anastomotic strictures, biliary lithiasis and sphincter of Oddi dysfunction in liver transplant recipients. Nevertheless, conventional T2-weighted MR cholangiography can be implemented with T1-weighted contrast-enhanced MR cholangiography using hepatobiliary contrast agents (in particular using Gd-EOB-DTPA) in order to improve the diagnostic accuracy in the adverse events' detection such as bile leakage and strictures, especially in selected patients with biliary-enteric anastomosis.

    The functional lifetime for biliary endoprostheses has typically been 7 months. When combined with sphincterotomy for common bile duct stones, it affords an alternative to surgery in high risk patients. Biliary endoprostheses often require replacement in these patients, though recent reports suggest they are functioning longer. We present an 85-year-old asymptomatic woman with a 6-year-old biliary endoprosthesis, believed to be the longest functioning stent reported in the literature. PMID:18493351

    To emphasize the importance of precocious diagnosis of extrahepatic biliary atresia and its direct relationship with the surgical re-establishment of the biliary flow before the second month of life. To discuss several complementary methods with the aim of selecting the ones that present better evidence, and avoiding delays in diagnosis and worse prognostic. Bibliographical researching regarding the period of 1985-2001, in Medline and MdConsult, using the following key words: neo-natal cholestasis; extrahepatic biliary atresia; neo-natal hepatitis. National and foreign articles were also elected based on the bibliography of consulted publications, and when necessary, for better understanding of the theme, opinions emitted in theses and textbooks were referred. The revision of the consulted bibliography led to the assumption that early diagnosis of EHBA and surgical treatment to reestablish the biliary flow up to 60 days of life are fundamental in order to achieve good results. Among several complementary methods of diagnosis, cholangiography by MR, US and the hepatic biopsy are the ones that provide the largest success indexes. The referring of patients bearers of EHBA to centers of references in Brazil, is still made tardily, probably due to lack of enlightenment of the doctors of primary attention, allied to bureaucratic and technological difficulties. The experience in England in relation to the "Yellow Alert" program, allowed that the number of children referred to surgical treatment before the 60 days of life increased significantly. Among the complementary methods, the MR cholangiography, ultrasonography and hepatic biopsy should be used, depending on the technological resources of the diagnosis units.

  16. Biliary atresia. A surgical perspective.

    The combination of portoenterostomy with subsequent liver transplantation is the treatment of choice for patients with biliary atresia. It is important, however, to attempt to keep the patient's own organ by continuing efforts to achieve the best possible results with portoenterostomy. Additional basic research, perhaps concerning on the role of cytokines and apoptosis in the control of biliary atresia, may provide insight into possible new medical strategies for treating patients with biliary atresia. For example, in addition to portoenterostomy, control of apoptosis at various cellular levels and of bile duct cell proliferation and maturation by manipulation of the growth factors and cytokines may become part of future treatment modalities. Another direction of research should be the control of fibrogenesis, which might be accomplished by blocking TGF-beta 1 and platelet-derived growth factor and by HGF gene therapy. The author's current strategy for surgical treatment for patients with biliary atresia include (1) early diagnosis, including prenatal diagnosis and broader use of mass screening programs, (2) hepatic portoenterostomy, without stoma formation; (3) close postoperative care, especially for prevention of postoperative cholangitis; (4) revision of portoenterostomy only in selected cases; (5) early liver transplantation in patients with absolutely failed portoenterostomy; (6) avoidance of laparotomy for the treatment of esophageal varices and hypersplenism; (7) consideration of exploratory laparotomy or primary liver transplantation for patients with advanced liver disease at the time of referral. The development of new treatment modalities based on the understanding of the pathogenesis of the disease, and especially on the biology of intrahepatic bile ducts and hepatic fibrosis, is essential.

    Chronic pancreatitis (CP) often leads to obstruction of one or all the components of the spleno-mesenterico-portal (SMP) axis. This is often due to the ongoing inflammatory process which may lead to thrombosis of the surrounding veins. However, the inflammation also leads to progressive fibrosis and occlusion of the veins without thrombosis. This fibrosis is also responsible for the duodenal obstruction and biliary strictures associated with CP. These patients, with simple occlusion or encasement of one or a combination of components of the SMP axis, can be treated with venous stenting. Here, we present the case of a 58-year-old gentleman with portal vein occlusion and portal biliopathy secondary to CP. This patient was successfully treated with percutaneous transhepatic portal vein stenting and a subsequent surgical biliary bypass. In conclusion, portal venous obstruction in CP may be just due to local fibrosis and is amenable to treatment with a percutaneously placed portal venous stent.

    There have been biliary complications since the beginning of liver transplants, and is a topic of great interest due to its high incidence, as well as their influence on morbidity and mortality. The biliary fistula is currently uncommon and its management is straightforward. Anastomotic stenosis continues to have an incidence of 10-15%. Although the current treatment of choice is endoscopic retrograde cholangiopancreatography (ERCP), surgical treatment (hepatico-jejunostomy) continues to have an important role. Non-anastomotic stenosis has an incidence of 5-10%, and is associated with ischaemic or immunological factors, and usually involves a re-transplant. Choledocholithiasis has an incidence of 5-10%, with the treatment of choice being ERCP. However the treatment of biliary complications should be individualised. We must take into account, liver function, the general health status of the patient, and the availability and experience of the team in the different therapeutic options. Copyright © 2011 AEC.

    Full Text Available Extrahepatic bile duct cancer is an uncommon disease, and few cases are curable by surgery. We report a case of extrahepatic biliary cystadenocarcinoma (BCAC associated with atrophy of the left hepatic lobe. A 54-year old male was admitted with painless obstructive jaundice and a hepatic palpable mass noticed one month before presentation. Liver functions tests were consistent with cholestatic damage and serum carbohydrate antigen 19.9 (CA 19-9 was increased before treatment. Magnetic resonance imaging (MRI disclosed dilatation of the left hepatic bile duct with irregular wall thickening close to the hepatic confluence, and atrophy of left hepatic lobe. The patient was submitted to en bloc extended left hepatectomy with resection of caudate lobe, hilar lymphadenectomy, and suprapancreatic biliary tree resection. All surgical margins were grossly negative, and postoperative course was uneventful, except for a minor bile leak. The patient was discharged on the 15th postoperative day; he is alive without tumor recurrence one year after primary therapy. Although technically challenging, extended en bloc resection is feasible in adults with extrahepatic BCAC and can improve survival with acceptable and manageable morbidity.

    Full Text Available 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.

    Here, we report the case of a 43-year-old man who was diagnosed with sigmoid colon cancer with synchronous multiple liver metastases following resection of a primary lesion. Subsequent mFOLFOX+BV therapy elicited a marked response in the liver metastases, which led to the patient undergoing hepatic (S7) radiofrequency ablation (RFA), hepatic resection (lateral segmentectomy and partial [S5] resection), and cholecystectomy. Six months later, transluminal RFA was repeated because liver (S7) metastasis recurred, and 8 courses of XELOX plus BV therapy were administered. As obstructive jaundice due to recurrence of the liver metastases developed after a 6 months hiatus in chemotherapy, we endoscopically inserted a biliary stent. Despite reducing IRIS plus BV therapy, obstructive jaundice developed again, and 3 intrahepatic biliary stents were inserted with percutaneous transhepatic biliary drainage. To date, the patient has been alive for 4 years since the initial resection of the primary lesion after undergoing consecutive systemic chemotherapy with different regimens. Some studies have shown that in cases of obstructive jaundice caused by advanced gastrointestinal cancer, longer survival could be expected by reducing the severity of jaundice, suggesting that resuming chemotherapy as well as improving the severity of jaundice could contribute to better outcomes. The patient in the present case was successfully treated twice with biliary drainage for occlusive jaundice and chemotherapy, suggesting that a combination of multidisciplinary therapy and adequate local therapy such as biliary drainage could be important for the treatment of metastatic liver cancer.

    Biliary cystadenoma (BCA) is a rare hepatic neoplasm. Although considered a benign cystic tumor of the liver, BCA has a high risk of recurrence with incomplete excision and a potential risk for malignant degeneration. Correct diagnosis and complete tumor excision with negative margins are the mainstay of treatment. Unfortunately, due to the lack of presenting symptoms, and normal laboratory results in most patients, BCA is hard to distinguish from other cystic lesions of the liver such as biliary cystadenocarcinoma, hepatic cyst, hydatid cyst, Caroli disease, undifferentiated sarcoma, intraductal papillary mucinous tumor, and hepatocellular carcinoma. Ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) may be necessary. They demonstrate intrahepatic cystic lesions with features such as mural nodules, varying wall thickness, papillary projections, and internal septations. Nevertheless, surgery is still the only means of accurate diagnosis. Definitive diagnosis requires histological examination following formal resection. We describe a 57-year-old woman initially diagnosed with polycystic liver who was subsequently diagnosed with giant intrahepatic BCA in the left hepatic lobe. This indicates that both US physicians and hepatobiliary specialists should attach importance to hepatic cysts, and CT or MRI should be performed for further examination when a diagnosis of BCA is suspected.

    Although the price of biliary metal stents is manyfold higher when compared to plastic stents, the lower frequency of recurrent obstructions makes metal stents superior to plastic stents for endoscopic palliation of malignant biliary stricture in most patients. Is this the case in extremely elderly patients as well? A retrospective data review comprising prospective data collection and double-entry bookkeeping of therapeutic endoscopic retrograde cholangiopancreatographies (ERCP) with biliary strictures referring to malignancy in 14 patients aged 90 years or older at our institution in 1997-2007. Plastic stents were successfully inserted in 11 out of 14 patients, yielding a technical success rate of 79 %. In the remaining three patients, high biliary obstruction was relieved percutaneously in two cases while the general condition of one patient was so poor that terminal care decision was made in that case. There was no recurrent biliary obstruction in any of the patients with plastic stents prior to death which occurred after a mean of 2.8 months, giving a clinical success rate of 100 %. To be concluded, in extremely elderly patients with malignant obstructive jaundice, palliation with plastic stent is effective enough.

    An acute obstruction of blood flow in central vessels of the systemic or pulmonary circulation causes the clinical symptoms of shock accompanied by disturbances of consciousness, centralization, oliguria, hypotension and tachycardia. In the case of an acute pulmonary embolism an intravascular occlusion results in an acute increase of the right ventricular afterload. In the case of a tension pneumothorax, an obstruction of the blood vessels supplying the heart is caused by an increase in extravascular pressure. From a hemodynamic viewpoint circulatory shock caused by obstruction is closely followed by cardiac deterioration; however, etiological and therapeutic options necessitate demarcation of cardiac from non-cardiac obstructive causes. The high dynamics of this potentially life-threatening condition is a hallmark of all types of obstructive shock. This requires an expeditious and purposeful diagnosis and a rapid and well-aimed therapy.

  5. Biliary Ascariasis: A difficult extraction

    Full Text Available Hepatobiliary ascariasis (HBA is a common complication of Ascaris infestation. It is reported mostly from developing countries. It is a common cause of biliary colic and cholangitis in some parts of India. It is also proposed as an etiology of a subset of patients with recurrent pyogenic cholangitis (RPC. Conservative management, endoscopic removal of the worm wherever needed and deworming is the accepted treatment approach. We herewith present a unique challenge that we encountered during worm removal. The patient was a 35-year-old female with 3 days history of epigastric pain, fever with rigors and vomiting. Her biochemical evaluation showed mild neutrophilic leukocytosis, mild elevation of aminotransferases and alkaline phosphatase. Ultrasound abdomen showed a tubular filling defect in the common bile duct extending in to the left hepatic duct. On endoscopic retrograde cholangiopancreatography (ERCP, the extraction was difficult because of left ductal stricture and a knot at the end of the worm. Such a worm conformation is rarely reported in the literature. In addition to presenting a challenge during removal it may act as a nidus for further infections and damage to the biliary tree particularly if the worm is dead or decaying. RPC is a disease with high morbidity and mortality. HBA is argued as an inciting event in significant number of cases. Recognition of such worm conformations emphasizes the need of meticulous ductal clearance at the time of ERCP, subsequent deworming and improved sanitation to protect such case from subsequent dreaded complications.

    To present the results of the biliary endoscopic approach (ERCP) followed by laparoscopic cholecystectomy (LC) in the management of biliary lithiasis (gallbladder and common bile duct--CBD). From 1997 to March 2003 37 patients with biliary lithiasis were treated by endoscopic sphincterotomy (ES) with stone extraction, followed after 24-48 hours by LC. The indications for ERCP were presence of an obstructive jaundice (n=32) and a dilated CBD at the ultrasound examination (n=5). Selective biliary cannulation was obtained in 35 (94.6%) cases, in all of them with successful papillotomy. Stones were found in all patients. CBD clearances for calculi (from 1 to 8) was obtained in 33 of 35 patients (94.3%), the rest of 2 being managed by open laparotomy. Antibiotics were administrated in all patients. Laparoscopic cholecystectomy was performed after 24-48 hours, with one conversion (3%). Postoperative morbidity was 12.1%: 2 transitory pancreatic reactions and 2 wound infections. Endo-Lap method is a useful management alternative for combined gallbladder and CBD lithiasis. It has all the advantages of the two mini-invasive procedures (fast recovery, short hospitalization, low costs) and a less postoperative morbidity in patients with high risk.

    Full Text Available Background: To study the aetiology, management and outcome of biliary perforations in paediatric age group. Patients and Methods: In a retrospective study, the records of patients presented with biliary peritonitis due to biliary perforations, managed from March 2006 to July 2009, are reviewed. Results: Eight male patients with biliary peritonitis due to biliary perforation were managed. These patients were divided in two groups, A and B. Group A, (n = 3 patients, had common bile duct (CBD perforation, and Group B (n=5 patients had gallbladder perforation. The presenting features were abdominal pain, fever, abdominal distension, vomiting, constipation, jaundice and signs of peritonism. The management of CBD perforations in Group A was by draining the site of perforation and biliary diversion (tube cholecystostomy. In Group B, the gallbladder perforations were managed by tube cholecystostomy in four patients and cholecystectomy in one patient, however, one patient had to be re-explored and cholecystectomy performed due to complete necrosis of gall bladder. There was no mortality in our series. All patients were asymptomatic on regular follow-up. Conclusion: Early optimal management of biliary perforations remarkably improved the very high mortality and morbidity that characterised this condition in the past.

    Chronic diseases of the biliary tree (cholangiopathies) represent one of the major unmet needs in clinical hepatology and a significant knowledge gap in liver pathophysiology. The common theme in cholangiopathies is that the target of the disease is the biliary tree. After damage to the biliary epithelium, inflammatory changes stimulate a reparative response with proliferation of cholangiocytes and restoration of the biliary architecture, owing to the reactivation of a variety of morphogenetic signals. Chronic damage and inflammation will ultimately result in pathological repair with generation of biliary fibrosis and clinical progression of the disease. The hallmark of pathological biliary repair is the appearance of reactive ductular cells, a population of cholangiocyte-like epithelial cells of unclear and likely mixed origin that are able to orchestrate a complex process that involves a number of different cell types, under joint control of inflammatory and morphogenetic signals. Several questions remain open concerning the histogenesis of reactive ductular cells, their role in liver repair, their mechanism of activation, and the signals exchanged with the other cellular elements cooperating in the reparative process. This review contributes to the current debate by highlighting a number of new concepts derived from the study of the pathophysiology of chronic cholangiopathies, such as congenital hepatic fibrosis, biliary atresia, and Alagille syndrome.

    Successful control of massive hemobilia by combined peripheral and proximal transcatheter embolization of the liver is described. Our patient had adenocarcinoma of the gallbladder with extension to the liver and invasion of intrahepatic and extrahepatic bile ducts. This caused hemobilia which became uncontrollable after percutaneous exchange of biliary drainage catheter that had been placed previously for relief of obstructive jaundice.

    Primary biliary cirrhosis (PBC) is characterized by antimitochondrial antibodies (AMA), directed to the E2 component of the pyruvate dehydrogenase complex (PDC-E2). Notwithstanding the presence of mitochondria in virtually all nucleated cells, the destruction in PBC is limited to small intrahepatic bile ducts. The reasons for this tissue specificity remain unknown, although biliary epithelial cells (BEC) uniquely preserve the PDC-E2 epitope following apoptosis. Notably, PBC recurs in an allogeneic transplanted liver, suggesting generic rather than host-PBC-specific susceptibility of BEC. We used cultured human intrahepatic BEC (HIBEC) and other well-characterized cell lines, including, HeLa, CaCo-2 cells, and non transformed human keratinocytes and bronchial epithelial cells (BrEpC), to determine the integrity and specific localization of PDC-E2 during induced apoptosis. All cell lines, both before and after apoptosis, were tested with sera from patients with PBC (n=30), other autoimmune liver and rheumatic diseases (n=20), and healthy individuals (n=20), a mouse monoclonal antibody against PDC-E2, and AMA with an IgA isotype. PDC-E2 was found to localize unmodified within apoptotic blebs of HIBEC, but not within blebs of various other cell lineages studied. The fact that AMA- containing sera reacted with PDC-E2 on apoptotic BEC without a requirement for permeabilization suggests that the autoantigen is accessible to the immune system during apoptosis. In conclusion, our data indicate that the tissue (cholangiocyte) specificity of the autoimmune injury in PBC is a consequence of the unique characteristics of HIBEC during apoptosis and can be explained by exposure to the immune system of intact immunoreactive PDC-E2 within apoptotic blebs.

    Biliary pseudolithiasis has been reported in patients who received ceftriaxone therapy. In addition to biliary sludge formation occasional reports of ceftriaxone-induced nephrolithiasis have been published. In general, these adverse effects will develop after seven to ten days of treatment. We report on a seven-year-old boy with ceftriaxone-associated biliary pseudolithiasis and nephrolithiasis four days after initiation of treatment. Patients receiving a high dose of ceftriaxone and developing colicky abdominal pain should be considered for ultrasound and a change in antibiotic therapy if appropriate.

    A total of 72 cases of internal biliary drainage procedure has been done percutaneously at Department of Radiology, Seoul National University Hospital for recent 4 and half years since August 1981. Five different types of internal drainage including endoprosthesis were applied to various conditions with different obstruction levels. The different method of procedure in each type of internal drainage was described and the results were analysed. 1. Among the clinical diagnosis in 72 cases, carcinoma of bile duct was in 37 cases as the most frequent one. The next was pancreas head carcinoma in 16 cases, followed by metastatic carcinoma and other diseases. 2. Type I internal drainage, classical internal and external type with distal end in duodenum, was applied in 43 cases as the most common one. Type II, modification of type I with distal end in CBD, was applied in 17 cases. Tyep III, endoprosthesis distal end into duodenum, was applied in 7 cases. Type IV, endoprosthesis just across the obstruction on bile duct, was applied in 2 cases, Type V, combined type of any internal drainage with external drainage, was applied in 3 cases. 3. According to various obstruction level, preferred type could be selected. For proximal obstruction type II and IV were preferred and for distal obstruction type III was chosen. However, type I could be applied in any situation. 4. Early complication occurred in 9 cases (12.5%). Clinical improvement with decrease in bilirubin level was observed in 17 of 21 cases in which follow-up data was available over 2 months. 5. Through the experience with those 72 cases it is recommended that appropriate type of internal biliary drainage should be selected according to prognosis, obstruction level and clinical findings of each patient.

    Rhinoliths are rare, intranasal, mineralized masses formed via the precipitation of mineral salts around an intranasal nidus. Clinical signs are typically consistent with inflammatory rhinitis and nasal obstruction, but asymptomatic cases are possible. Rhinoliths may be classified as exogenous or endogenous depending on the origin of the nidus, with endogenous rhinoliths reportedly being less common. This case report describes a suspected case of endogenous rhinolithiasis in a cat which was detected as an incidental finding during radiographic assessment of a maxillary canine tooth with endodontic disease. Treatment consisted of removal of the suspected rhinolith via a transalveolar approach after surgical extraction of the maxillary canine tooth.

    Andrew Y Lee

    Full Text Available PURPOSE: To evaluate the efficacy of percutaneous balloon dilation of biliary-enteric anastomotic strictures resulting from surgical repair of laparoscopic cholecystectomy-related bile duct injuries. MATERIAL AND METHODS: A total of 61 patients were referred to our institution from 1995 to 2010 for treatment of obstruction at the biliary-enteric anastomosis following surgical repair of laparoscopic cholecystectomy-related bile duct injuries. Of these 61 patients, 27 underwent surgical revision upon stricture diagnosis, and 34 patients were managed using balloon dilation. Of these 34 patients, 2 were lost to follow up, leaving 32 patients for analysis. The primary study objective was to determine the clinical success rate of balloon dilation of biliary-enteric anastomotic strictures. Secondary study objectives included determining anastomosis patency, rates of stricture recurrence following treatment, and morbidity. RESULTS: Balloon dilation of biliary-enteric anastomotic strictures was clinically successful in 21 of 32 patients (66%. Anastomotic stricture recurred in one of 21 patients (5% after an average of 13.1 years of follow-up. Patients who were unsuccessfully managed with balloon dilation required significantly more invasive procedures (6.8 v. 3.4; p = 0.02 and were left with an indwelling biliary catheter for a significantly longer period of time (8.8 v. 2.0 months; p = 0.02 than patients whose strictures could be resolved by balloon dilation. No significant differences in the number of balloon dilations performed (p = 0.17 or in the maximum balloon diameter used (p = 0.99 were demonstrated for patients with successful or unsuccessful balloon dilation outcomes. CONCLUSION: Percutaneous balloon dilation of anastomotic biliary strictures following surgical repair of laparoscopic cholecystectomy-related injuries may result in lasting patency of the biliary-enteric anastomosis.

  18. Primary Biliary Cirrhosis: Family Stories

    Directory of Open Access Journals (Sweden)

    Daniel Smyk

    2011-01-01

    Full Text Available Primary biliary cirrhosis (PBC is a chronic immune-mediated cholestatic liver disease of unknown aetiology which affects mostly women in middle age. Familial PBC is when PBC affects more than one member of the same family, and data suggest that first-degree relatives of PBC patients have an increased risk of developing the disease. Most often, these familial clusters involve mother-daughter pairs, which is consistent with the female preponderance of the disease. These clusters provide evidence towards a genetic basis underlying PBC. However, clusters of nonrelated individuals have also been reported, giving strength to an environmental component. Twin studies have demonstrated a high concordance for PBC in monozygotic twins and a low concordance among dizygotic twins. In conclusion, studies of PBC in families clearly demonstrate that genetic, epigenetic, and environmental factors play a role in the development of the disease.

    Primary biliary cirrhosis (PBC) is an autoimmune disease of the liver characterized by progressive bile duct destruction eventually leading to cirrhosis and liver failure. The serological hallmark of the disease is the presence of circulating antimitochondrial antibodies (AMA). These reflect the presence of autoreactive T and B cells to the culprit antigens, the E2 subunits of mitochondrial 2-oxo-acid dehydrogenase enzymes, chiefly pyruvate dehydrogenase (PDC-E2). The disease results from a combination of genetic and environmental risk factors. Genetic predisposition is indicated by the higher familial incidence of the disease particularly among siblings and the high concordance rate among monozygotic twins. Environmental triggering events appear crucial to disrupt a pre-existing unstable immune tolerance of genetic origin allowing, after a long latency, the emergence of clinical disease. Initiating mimotopes of the vulnerable epitope of the PDC-E2 autoantigen can be derived from microbes that utilize the PDC enzyme or, alternatively, environmental xenobiotics/chemical compounds that modify the structure of native proteins to make them immunogenic. A further alternative as a source of antigen is PDC-E2 derived from apoptotic cells. In the effector phase the biliary ductular cell, by reason of its proclivity to express the antigen PDC-E2 in the course of apoptosis, undergoes a multilineage immune attack comprised of CD4+ and CD8+ T cells and antibody. In this article, we critically review the available evidence on etiopathogenesis of PBC and present interpretations of complex data, new developments and theories, and nominate directions for future research.

    Biliary cystadenoma is a rare benign cystic tumor of the liver. The mainstay of treatment is complete resection, either by enucleation or by formal hepatectomy, since incomplete removal entails not only constant recurrence but also the risk of malignant transformation to cystadenocarcinoma. A case of symptomatic centrohepatic biliary cystadenoma involving the main vasculobiliary structures of the liver is reported. After an unsuccessful attempt at resection resulting in an intrahepatic biliary injury, relief of jaundice and radical excision were achieved by total hepatectomy and liver transplantation. The patient is now alive and well 4 years after transplant, disease-free, with normal liver and renal function while receiving everolimus monotherapy. This is the first report of liver transplantation performed for the treatment of this tumor. With the case on the background, diagnostic aspects and available therapeutic strategies for biliary cystadenoma are reviewed and discussed. Copyright © 2011. Published by Elsevier Masson SAS.

    Purpose: To identify the diagnostic value of ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) in diagnosing biliary strictures after liver transplantation. Materials and methods: Sixty patients with clinically suspected biliary strictures after liver transplantation were retrospectively evaluated. All patients underwent US and MRCP before the standard of reference (SOR) procedure: endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography. Radiological images were analyzed for biliary dilatation and strictures. Results: By SOR, biliary dilatation was present in 55 patients, stricture in 53 (44 anastomotic, 4 intrahepatic, 5 both), and dilatation and/or stricture in 58. Dilatation was diagnosed by US and MRCP in 39 and 45, respectively (sensitivity 71% vs. 82%, p = 0.18). Stricture was diagnosed by US and MRCP in 0 and 42, respectively (sensitivity 0% vs. 79%, p < 0.0001). False positive stricture was diagnosed by MRCP in 2. Dilatation and/or stricture was diagnosed by US in 39 and MRCP in 50 (sensitivity 67% vs. 86%, p = 0.01); however, using both techniques, sensitivity increased to 95%. Conclusions: MRCP is superior to US for diagnosing biliary strictures after liver transplantation primarily because MRCP can detect stricture. The combination of US and MRCP seems superior to either method alone. Our data suggest that in patients with normal US and MRCP, direct cholangiography could be avoided.

    1991-12-01

    Endoscopic retrograde cholangiopancreatography (ERCP) was successfully performed in 49/50 consecutive patients with acute pancreatitis and suspected biliary aetiology in the early phases of the disease (24-72 hours from admission). ERCP showed common bile duct lithiasis and/or stenosis (25 cholecystectomized patients) in 41/49 cases (83.7%). In 38 patients endoscopic sphincterotomy (ES) was performed: stone removal was possible in lithiasic patients (36 cases, 13 previously cholecystectomized); 3 further patients showed a main pancreatic duct stenosis (2 of these underwent pancreatic ES). The patients treated with ES showed a quick improvement in symptomatology and clinical outcome; no adverse effect of ERCP was found; no mortality was registered. Comparison with a previous series of 130 cases of acute biliary pancreatitis (ABP) showed a reduction in mortality, complications and length of hospitalization. These findings suggest that, from a diagnostic and therapeutic point of view, early ERCP is safe and useful in ABP.

    The authors present 17 cases of patients with internal biliary fistulae of lithiasic origin. Nine of these were of the cholecystoduodenal type, 2 of the cholecysto-gastric type, 2 had developed between the cholecyst and the colon, and 4 were of the bilio-biliary type, between the cholecyst and the choledochus. These cases represented 1.1% of the 1,500 interventions carried out on the extra-hepatic biliary pathways over a period of 10 years, between 1971 and 1980, and 13% of the total number of interventions performed for biliary lithiasis. The advanced age of the patients, the background disease and the complications that accompanied it, as well as the associated deficiencies have given rise to diagnostic and therapeutic difficulties. A correct diagnosis before surgery was made in only two of the patients. The postoperative evolution was good in 13 of the cases (representing 76% of the total), and this confirmed the correct surgical attitude which aimed at restoration of the physiological conditions and a normal digestive and biliary transit. In cases with biliary ileus the first therapeutic measure was to secure intestinal transit.

    Biliary cysts (BC) are rare dilatations of different parts of a biliary tract. They account for approximately 1% of all benign biliary diseases. BC occur the most frequently in Asian and female populations. They are an important problem for pediatricians, gastroenterologists, radiologists and surgeons. Clinical presentation and management depend on the BC type. Cholangiocarcinoma is the most serious and dangerous BC complication. The other complications associated with BC involve cholelithiasis and hepatolithiasis, cholangitis, acute and chronic pancreatitis, portal hypertension, liver fibrosis and secondary liver cirrhosis and spontaneous cyst perforation. Different BC classifications have been described in the literature. Todani classification dividing BC into five types is the most useful in clinical practice. The early diagnosis and proper treatment are very important, because BC are associated with a risk of carcinogenesis. A malignancy risk increases with the age. Radiological investigations (ultrasonography, computed tomography, endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography) play an important role in BC diagnostics. Currently, prenatal diagnosis using ultrasonography is possible. It allows to differentiate biliary disorders in fetals and to perform the early surgical treatment that improves results. In most patients, total cyst excision with Roux-Y hepaticojejunostomy is the treatment of choice. Surgical treatment of BC is associated with high success rate and low morbidity and mortality. The early treatment is associated with a lower number of complications. Patients following BC surgery require permanent and careful postoperative observation using laboratory and imaging investigations because of possibility of biliary anastomosis stricture and biliary cancer in tissue remnant.

  8. Silencing of the rotavirus NSP4 protein decreases the incidence of biliary atresia in murine model.

    Directory of Open Access Journals (Sweden)

    Jiexiong Feng

    Full Text Available Biliary atresia is a common disease in neonates which causes obstructive jaundice and progressive hepatic fibrosis. Our previous studies indicate that rotavirus infection is an initiator in the pathogenesis of experimental biliary atresia (BA through the induction of increased nuclear factor-kappaB and abnormal activation of the osteopontin inflammation pathway. In the setting of rotavirus infection, rotavirus nonstructural protein 4 (NSP4 serves as an important immunogen, viral protein 7 (VP7 is necessary in rotavirus maturity and viral protein 4 (VP4 is a virulence determiner. The purpose of the current study is to clarify the roles of NSP4, VP7 and VP4 in the pathogenesis of experimental BA. Primary cultured extrahepatic biliary epithelia were infected with Rotavirus (mmu18006. Small interfering RNA targeting NSP4, VP7 or VP4 was transfected before rotavirus infection both in vitro and in vivo. We analyzed the incidence of BA, morphological change, morphogenesis of viral particles and viral mRNA and protein expression. The in vitro experiments showed NSP4 silencing decreased the levels of VP7 and VP4, reduced viral particles and decreased cytopathic effect. NSP4-positive cells had strongly positive expression of integrin subunit α2. Silencing of VP7 or VP4 partially decreased epithelial injury. Animal experiments indicated after NSP4 silencing, mouse pups had lower incidence of BA than after VP7 or VP4 silencing. However, 33.3% of VP4-silenced pups (N = 6 suffered BA and 50% of pups (N = 6 suffered biliary injury after VP7 silencing. Hepatic injury was decreased after NSP4 or VP4 silencing. Neither VP4 nor VP7 were detected in the biliary ducts after NSP4. All together, NSP4 silencing down-regulates VP7 and VP4, resulting in decreased incidence of BA.

    Recently, with improvements in surgical techniques there has been a substantial reduction in the incidence of biliary complications of hepatobiliary surgery. Nevertheless, bile duct injuries and other post-cholecystectomy complications are a serious problem and a major cause of morbidity and mortality. Early complications may include bile duct injury caused by mistakenly placed clips, erroneous cutting of bile ducts based on misinterpretation of biliary anatomy, periductal bile leakage that causes edema, fibrosis and secondary stricturing, and ischemia due to injury to the right hepatic artery. Bile duct strictures are the most common of the late complications and can develop a few months or many years after surgery. Early detection and accurate diagnosis have a fundamental importance for the successful treatment of these complications. Therefore, early and meaningful application of the imaging methods immediately after detection of the first symptoms is essential. Peroperative ultrasound and direct iodine contrast application into the biliary tree (operative cholangiography) are highly important for immediate visualization of the complications during surgery. Ultrasound can be used to aid in identification of ductal structures and the cholangiogram should be obtained to document the anatomy. Plain abdominal film could be made in the patients in poor clinical conditions after biliary surgery. Oral cholecystography has largely been replaced by ultrasonography (US) for evaluation of cholelithiasis and complications like post-cholecystectomy fluid collections. The same methodology replaced the conventional intravenous cholangiography. Nowadays computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), magnetic resonance cholangiography (MRCP) and ultrasound (US) have essential roles as primary imaging modalities after biliary tree and gallbladder surgery in the evaluation of associated complications and residual biliary stones. We review the role

    Full Text Available Sarah M Desoky,1 Ranjit I Kylat,2 Unni Udayasankar,1 Dorothy Gilbertson-Dahdal1 1Department of Medical Imaging, University of Arizona College of Medicine, Tucson, AZ, USA; 2Division of Neonatal-Perinatal Medicine, Department of Pediatrics, University of Arizona College of Medicine, Tucson, AZ, USA Abstract: Neonatal intestinal obstruction is a common surgical emergency and occurs in approximately 1 in 2,000 live births. The causes of obstruction are diverse with varied embryological origins, and some underlying etiologies are not yet well described. Some findings of neonatal bowel obstruction can be detected prenatally on ultrasound imaging. The obstruction is classified as “high” when the level of obstruction is proximal to the ileum, and “low” when the level of obstruction is at the ileum or colon. Early diagnosis of the type of intestinal obstruction and localization of the obstructive bowel segment guides timely and appropriate management of the underlying pathologic entity. Neonatal bowel obstructions are ideally managed at specialized centers with a large volume of neonatal surgery and dedicated pediatric surgical and anesthesia expertise. Although surgical intervention is necessary in most cases, initial management strategies often target underlying metabolic, cardiac, or respiratory abnormalities. Imaging plays a key role in early and accurate diagnosis of the abnormalities. When bowel obstruction is suspected clinically, initial imaging workup usually involves abdominal radiography, which may direct further evaluation with fluoroscopic examination such as upper gastrointestinal (UGI contrast study or contrast enema. This article provides a comprehensive review of clinical and radiological features of common and less common causes of intestinal obstruction in the neonatal age group, including esophageal atresia, enteric duplication cysts, gastric volvulus, congenital microgastria, hypertrophic pyloric stenosis, duodenal atresia

    Obstructive jaundice related to stricture and stone in cystic duct was found in a patient 6 years after liver transplantation and cholecystojejunostomy. Complications with biliary drainage following liver transplantation are discussed. In the presence of dilated ducts seen by ultrasound, percutaneous transhepatic cholangiography performed immediately can lead to surgical correction, thus preventing failure of the liver transplant.

    Portal biliopathy is a rare complication of extrahepatic portal vein obstruction. Jaundice occurs in symptomatic patients with fibrotic strictures. Short-term improvement in such patients can be achieved with endoscopic retrograde cholangio-pancreatography with balloon dilatation and stent placement. Surgery in these patients is traditionally two staged. We report the results of a one-stage procedure combining non-selective portal-systemic shunt surgery with biliary bypass, performed successfully on a 24-year-old man with a tight biliary stricture resulting from portal biliopathy. At 18-month follow up, the patient shows he is doing well, with normal liver function tests.

    A 54-year-old woman suffering from pruritus for five years was diagnosed to have Graves' disease and immune thrombocytopenia (ITP) associated with primary biliary cirrhosis (PBC)-autoimmune hepatitis (AIH) overlap syndrome, which was confirmed histologically after a prompt recovery in the platelet count number following steroid therapy. The association between PBC-AIH overlap syndrome and ITP has been rarely reported and the additional association with Graves' disease has not yet been reported. An underlying global derangement of autoimmunity or shared genetic susceptibility was suspected.

    The aetiological role of biliary lithiasis for chronic pancreatitis remains controversial. Previous studies based on pancreatographic studies reported changes in the pancreatic duct system caused by biliary lithiasis. This study analysed retrospectively the endoscopic retrograde cholangiopancreatography of 165 patients presenting with biliary lithiasis and of 53 controls. Among the 165 patients, 113 had choledochal stones (53 with gall bladder stones, 50 had had a cholecystectomy, 10 with a normal gall bladder), 35 had gall bladder stones without choledochal stones, 17 had cholecystectomy for gall bladder stones. Pancreatograms were analysed by measuring the diameter of the pancreatic duct in the head, the body, and the tail of the pancreas, and evaluating the regularity of the main pancreatic duct and the presence of stenosis, the regularity or the dilatation of secondary ducts, and the presence of cysts. In addition, we established a score, based on the above parameters, by which pancreatograms were classified as normal or with mild, intermediate, moderate or severe abnormalities. A multivariate analysis (stepwise multiple discriminant analysis) was performed for age, sex, presence of gall stones, presence of choledochal stones. Patients were comparable with controls for sex, alcohol consumption but were younger (55 v 68 years, p biliary lithiasis in itself is not an aetiological factor for chronic pancreatitis, older age being responsible for the abnormalities seen by pancreatography of patients with biliary lithiasis.

    Chronic lythiasic cholecystitis is a disease distinguished by the pathologic changes because of the chronic inflammation of the biliary extrahepatic tree. Sometimes these morphological changes are associated with internal biliary fistulas arising spontaneously in patients with advanced calculus cholecystitis. The vast majority of fistulas result from the adherence of the inflamed gallbladder or common bile duct to an adjacent viscus and erosion of the gallstones into the adherent organ. The authors analyze an amount of 43 patients with bilio-biliary and bilio-digestive lythiasic fistulas, caused by the long evolution of chronic lythiasic atrophic cholecystitis, for 126 cases which were operated in the Surgery Department of the Caritas Clinic Hospital along 20 years. In these 126 cases the surgical strategy was determinated by the method of dealing with the pericolecystitis sclerotic blocks, by the identification methods of the biliary elements and by the approach of the main billiary way and digestive loops injuries occurred after suppressing the fistulae. The surgical solutions adapted for each separate case and the advantages of the axial drainage of prostheting the surgical reconstructions of the main biliary way as well as the results obtained along this project, are in fact the aims of this presentation.

    The pathway from clinical suspicion to establishing the diagnosis of biliary atresia in a child with jaundice is a daunting task. However, investigations available help to point towards the correct diagnosis in reasonable time frame. 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. The place of surgical management in biliary atresia is undisputed, although Kasai procedure and primary liver transplantation have been pitted against each other. This article functions as a platform to bring forth the various dimensions of biliary atresia.

    Retrograde cholangiography was conducted in 310 patients early or late after biliary system surgery. Principal indications for the investigation were angiocholitis (37% of cases), isolated jaundice (30%) or acute hepatic colic (17%). Biliary tract lesions were excluded in 7% of patients while in the remaining 93% it was possible to determine the precise cause of the disorder. In 30% of cases the disorder was unrelated to the previous operation or the lithiasic disease, whereas in 63% it was related to the latter (remaining or reformed stone, odditis) or to the surgical procedure (stenosis, common bile duct ligature or injury to main bile duct). These results, and those reported in the ligature, suggest that retrograde cholangiography can provide a precise diagnosis and ensure adapted therapy after biliary surgery.

    Biliary strictures are considered indeterminate when basic work-up, including transabdominal imaging and endoscopic retrograde cholangiopancreatography with routine cytologic brushing, are non-diagnostic. Indeterminate biliary strictures can easily be mischaracterized which may dramatically affect patient’s outcome. Early and accurate diagnosis of malignancy impacts not only a patient’s candidacy for surgery, but also potential timely targeted chemotherapies. A significant portion of patients with indeterminate biliary strictures have benign disease and accurate diagnosis is, thus, paramount to avoid unnecessary surgery. Current sampling strategies have suboptimal accuracy for the diagnosis of malignancy. Emerging data on other diagnostic modalities, such as ancillary cytology techniques, single operator cholangioscopy, and endoscopic ultrasonography-guided fine needle aspiration, revealed promising results with much improved sensitivity.

    Biliary atresia (BA) is an infantile obstructive cholangiopathy of unknown etiology with suboptimal therapy, which is responsible for 40 to 50% of all pediatric liver transplants. Although the etiology of bile duct injury in BA in unknown, it is postulated that a pre- or perinatal viral infection initiates cholangiocyte apoptosis and release of antigens that trigger a Th1 immune response that leads to further bile duct injury, inflammation, and obstructive fibrosis. Humoral immunity and activation of the innate immune system may also play key roles in this process. Moreover, recent investigations from the murine BA model and human data suggest that regulatory T cells and genetic susceptibility factors may orchestrate autoimmune mechanisms. What controls the coordination of these events, why the disease only occurs in the first few months of life, and why a minority of infants with perinatal viral infections develop BA are remaining questions to be answered.

    We present a case of a biliary cystadenoma, a rare benign cystic tumor arising in most cases of the intrahepatic bile ducts. A 30-year old woman presented with abdominal pain in the right upper quadrant for about 10 days with increasing severity. Radiological evaluation by means of abdominal ultrasound and CT-scan revealed a multilocular cystic lesion in the right liver lobe, not present on abdominal ultrasound performed 10 years before. The diagnosis of a biliary cystadenoma was proposed and complete surgical resection of the mass was performed.

    The possibilities are discussed offered by computed tomography in the diagnosis of biliary tract diseases. Attention is paid to difficulties associated with the diagnosis of pathological changes in the biliary tract, and to the detection of isodense concrements where diagnostic problems are reliably resolved by PTHC and ERCP. It is therefore useful to supplement CT with other examination methods. A suitable combination is cholescintigraphy and CT with the possibility of a final diagnosis or selection of further examination, as a rule of an invasive nature.

    Magnetic compression anastomosis (MCA) has been developed as a non-surgical alternative treatment for biliary obstruction without serious complications. A 70-year-old woman who had undergone pancreaticoduodenectomy with modified Child reconstruction for pancreatic head cancer suffered from obstructed choledochojejunostomy with no recurrent findings 4 months after the operation. Cholangiography using the percutaneous transhepatic cholangiographic drainage (PTCD) and fluoroscopy revealed complete obstruction of the upper common bile duct, and the length of the obstruction was 7 mm. Intraductal ultrasonography (IDUS) showed fibrous heterogenous hyperechoic appearance without fluid collection, vessels or foreign bodies at the site of the obstruction. We performed choledochojejunostomy using the MCA technique. One magnet was inserted into the obstruction of the hepatic side through the PTCD fistula. Another was delivered endoscopically to the obstruction of the jejunal side. The two magnets were immediately attracted towards each other transmurally, and reanastomosis was confirmed 7 days after starting the compression. The magnets were easily retrieved endoscopically. A 16-Fr indwelling drainage tube was placed in the jejunum through the PTCD. The internal tube is still in place 6 months after reanastomosis, and no MCA-related complications have been observed. In conclusion, MCA is a safe, effective, low-invasive treatment for biliary obstruction, and IDUS is useful for the pretreatment assessment of feasibility and safety.

    Full Text Available Introduction. Hepatic peribiliary cysts (HPCs usually originate due to the cystic dilatation of the intrahepatic extramural peribiliary glands. We describe our rare experience of pure laparoscopic left hemihepatectomy (PLLH in a patient with HPCs accompanied by a component of biliary intraepithelial neoplasia (BilIN. Case Presentation. A 65-year-old man was referred for further investigation of mild hepatic dysfunction. Contrast-enhanced computed tomography showed dilatation of the left-sided intrahepatic bile duct, and biliary cytology showed class III cells. The patient was highly suspected of having left side-dominated cholangiocarcinoma and underwent PLLH. Microscopic findings revealed multiple cystic dilatations of the extramural peribiliary glands; hence, this lesion was diagnosed as HPCs. The resected intrahepatic bile duct showed that the normal ductal lumen comprised low columnar epithelia; however, front formation on the BilIN was observed in some parts of the intrahepatic bile duct, indicating that the BilIN coexisted with HPCs. Conclusion. We chose surgical therapy for this patient owing to the presence of some features of biliary malignancy. We employed noble PLLH as a minimally invasive procedure for this patient.

    The paper shows the role of biliary dysfunction in the formation of biliary sludge. Found that among all motor dysfunction themost common is reduction of contractile function of the gallbladder (in 63.3% of cases), which is combined with 73.2% Oddi's sphincter hypertonus. T The combination of ursodeoxycholic acid (UDCA) with mebeverine has a better effect than monotherapy with UDCA, as increases the frequency of relief of biliary dyspepsia symptoms, normalizes the biliary tract functional status and 95% of cases leads to the elimination of biliary sludge.

    Eleven patients with an obstructed, fluid-filled uterus, due to carcinoma of the uterus or to its treatment by radiation therapy, were examined with computed tomography (CT) and/or ultrasound. It is important to recognize this abnormality to differentiate it from other causes of pelvic mass and to ensure prompt treatment of pyometra, should it develop. Both CT and ultrasound reliably identified this condition and differentiated it from other pelvic masses.

    Biliary cystadenomas are benign but potentially malignant cystic neoplasms, which classically contain mesenchymal stroma similar to ovarian tissue. We report a case of an extra-hepatic biliary cystadenoma with mesenchymal stroma along with a discussion of current pathological opinion. CASE PRESENTATION: A 54-year-old female presented with abdominal pain, abnormal liver function tests and a mass on ultrasound. Computerized Tomography identified a complex multi-locular cyst in the common hepatic duct. Radical excision of the lesion and a Roux-en-Y loop bilio-enteric anastomosis was performed. Histology confirmed the presence of a benign biliary cystadenoma with ovarian type stroma. CONCLUSION: Biliary cystadenomas classically contain mesenchymal stroma similar to ovarian tissue. It now appears that cystadenomas without mesenchymal stroma appear to be more akin to similar cystic lesions of the pancreas, and may represent a dissimilar neoplasm. Therefore, malignant transformation can occur, so complete excision is recommended.

    Endoscopic retrograde cholangiopancreatography (ERCP), with or without sphincterotomy, has been widely used in patients with severe biliary acute pancreatitis (BAP) or those with cholangitis and/or obstruction of the biliary tree. Its use in subjects with mild BAP is more controversial. To optimize use of ERCP in patients with mild pancreatitis due to gallstones by identifying clinical and biochemical predictors of choledocholithiasis. The clinical and biochemical data, images, and outcomes of 83 patients with mild BAP hospitalized at the Instituto Nacional de Ciencias Medicas y Nutricion "Salvador Zubiran" from January 1, 1988 to May 30, 2000 were retrospectively analyzed. All patients received elective cholecystectomy at hospital admission. In 35 cases, ERCP was performed before cholecystectomy (group A). The remaining 48 were operated on without ERCP (group B). In 30, transcystic-cholangiography was done. Forty-seven (57%) were female. Mean age was 47 years (19-90). Mean time between onset of AP and hospital admission was 2.2 days (1-15), and between clinical onset and cholecystectomy, eight days (1-26). Statistical differences were evaluated by non-parametric methods. An univariated and multivariated analysis was performed looking for data to identify choledocholithiasis. Choledocholithiasis was found in 27 cases (32%), 18 from group A (51%), and nine for group B (19%) (RR = 4.58, IC 95% = 1.7-12.25, p = 0.004). ERCP was performed in all cases because of clinical suspicion of choledocholithiasis (jaundice, bilirubin, and alkaline phosphatase alteration and/or choledochal dilation); however, none of the patients of group B in whom choledocholithiasis was operatively diagnosed showed biochemical or radiologic alterations. Subjects with choledocolithiasis presented more frequently a history of biliary pain (RR = 5.75, IC 95% = 1.76-18.7), jaundice (RR = 3.07, IC 95% = 1.15-8.16) and/or alkaline phosphatase elevation (RR = 4.11, IC 95% = 1.3-12.7).

    Biliary dyskinesia is a functional gastrointestinal disorder of the gallbladder and sphincter of Oddi. Diagnosis is made on the basis of symptoms of biliary colic in the absence of cholelithiasis and gallbladder inflammation. Palpatory findings of tissue texture changes at midthoracic levels (T6-T9) may correspond to visceral dysfunction related to the biliary system. Osteopathic manipulative treatment (OMT) of the T6-T9 segments can remove the feedback related to the somatic component, thereby affecting nociceptive facilitation at the spinal level and allowing the body to restore autonomic balance. Few reports in the current literature provide examples of treatment for patients with biliary dyskinesia using OMT. The author describes the case of a 51-year-old woman who presented with symptoms consistent with biliary dyskinesia. Her biliary colic completely resolved after OMT. Osteopathic evaluation and OMT should be considered a safe and effective option for conservative management of biliary dyskinesia.

    To evaluate the difference in each procedure time and complication rates related to percutaneous transhepatic biliary drainage(PTBD) via the right and the left hepatic lobe. We performed PTBD in 120 patients with biliary obstruction below both main hepatic ducts. Of the 120 catheters, 54 were introduced via a left lobe approach and 66 through the right lobe. All procedures were performed under fluoroscopic guidance by the same operator. For each patient, procedure time was recorded prospectively. PTBD related complications were classified as either early(up to 30 days after procedure) or late(after 30 days), and each complication graded as major, or minor according to its intensity. The difference in the mean procedure time(28.8 min, versus 36.2 min, left versus right approach group) and that in complication rates (37% versus 58%) were statistically significant({rho} < 0.05). Concerning major complication(bile peritonitis, sepsis, massive hemobilia, liver abscess, pyothorax), the percentages related to left and right lobe approach were 1.8% and 10.6%, and concerning minor complications(catheter obstruction or dislodgement, transient hemobilia, persistent fever or pain), the percentages were 36% and 51% respectively. PTBD via the left lobe approach was superior with short procedure time and low complication rates than the right approach.

    Biliary cystadenomas are predominately benign tumours that have a low malignant potential. We present a case of a 30-year-old female with a histopathological confirmation of a biliary cystadenoma following resection. The diagnosis was made pre-operatively by MRI using the hepatocyte-specific contrast agent gadobenate dimeglumine (Gd-BOPTA) (MultiHance; Bracco Diagnostics Inc., Princeton, NJ). At the biliary excretory phase, delayed phase images demonstrated communication between the multilocular cystic mass and the biliary tree, which helped to confirm the diagnosis of biliary cystadenoma. This highlights the beneficial use of hepatocyte-specific agents for their dual function as an extracellular agent and a hepatobiliary agent.

    To identify the diagnostic value of ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) in diagnosing biliary strictures after liver transplantation. Sixty patients with clinically suspected biliary strictures after liver transplantation were retrospectively evaluated. All patients underwent US and MRCP before the standard of reference (SOR) procedure: endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography. Radiological images were analyzed for biliary dilatation and strictures. By SOR, biliary dilatation was present in 55 patients, stricture in 53 (44 anastomotic, 4 intrahepatic, 5 both), and dilatation and/or stricture in 58. Dilatation was diagnosed by US and MRCP in 39 and 45, respectively (sensitivity 71% vs. 82%, p=0.18). Stricture was diagnosed by US and MRCP in 0 and 42, respectively (sensitivity 0% vs. 79%, pliver transplantation primarily because MRCP can detect stricture. The combination of US and MRCP seems superior to either method alone. Our data suggest that in patients with normal US and MRCP, direct cholangiography could be avoided.

    It is necessary to establish effective chemotherapy to improve the survival of patients with biliary tract cancer, because most of these patients are unsuitable candidates for surgery, and even patients undergoing curative surgery often have recurrence. Recently, the combination of cisplatin plus gemcitabine was reported to show survival benefits over gemcitabine alone in randomized clinical trials conducted in the United Kingdom and Japan. Thus, the combination of cisplatin plus gemcitabine is now recognized as the standard therapy for unresectable biliary tract cancer. One of the next issues that need to be addressed is whether molecular targeted agents might also be effective against biliary tract cancer. Although some targeted agents have been investigated as monotherapy for first-line chemotherapy, none were found to exert satisfactory efficacy. On the other hand, monoclonal antibodies such as bevacizumab and cetuximab have also been investigated in combination with a gemcitabine-based regimen and have been demonstrated to show promising activity. Furthermore, clinical trials using new targeted agents for biliary tract cancer are also proposed. This cancer is a relatively rare and heterogeneous tumor consisting of cholangiocarcinoma and gallbladder carcinoma. Therefore, a large randomized clinical trial is necessary to confirm the efficacy of chemotherapy, and international collaboration is important.

    Full Text Available Abstract Background It is acknowledged that total cyst excision is a safe and ideal surgical treatment for congenital biliary duct cyst, compared to simple internal drainage. The aim of this study was to determine the optimal operation occasion and the effect of laparoscopy on congenital biliary duct cyst based upon total cyst excision. Methods From January 2002 to January 2011, 217 patients were admitted to Southwest Hospital for congenital biliary duct cyst. To determine the optimal surgery occasion, we divided these subjects into three groups, the infant group (age ≤ 3 years, the immaturity group (3 18 years, and then evaluated the feasibility, risk and long-term outcome after surgery in the three groups. To analyze the effect of laparoscopic technique on congenital biliary duct cyst, we divided the patients into the laparoscopy and the open surgery groups. Results Among the three groups, the morbidity from cholangiolithiasis before surgical treatment had obvious discrepancy (p 0.05. Similarly, no significant discrepancy was observed in the morbidity from postoperative complications or long-term postoperative complications (p > 0.05 between the laparoscopic and the open surgery groups. Conclusions We conclude that total cyst excision should be performed as early as possible. The optimal treatment occasion is the infant period, and laparoscopic resection may be a new safe and feasible minimally invasive surgery for this disease.

There are two forms of biliary atresia: embryonic form, associated with another visceral malformations, and perinatal form, which is an isolated disease. Biliary atresia is a heterogeinc disease which may appear as a result of different etiological factors, the most important of them are genetics, viral infection, vascular factors, toxins and disregulation of immune system. The characteristic morphological features of biliaryatresia are: intracellular and ductular cholestasis, ductular proliferation, giant cell transformation, portal and perilobular oedema and/or fibrosis. As the patalogical process progresses, ductopenia appears, and fibrosis turns to cirrhosis. Embryonic form mophologically manifests with ductal plate malformation is, what is an important diagnostic criterion. Pro- gnosis of biliary atresia depends on form of disease, age of patient and type of surgical operation. Today surgical treatment includes two steps: palliative portoenterostomia, performed in neonatal period and further liver trans- plantation. However liver transplantation is more preferable as first and single-step treatment.

    Previous work has shown that in humans the dose-limiting toxicity for fluorodeoxyuridine [2-fluoro-5'-deoxyuridine (FdUrd)] when administered by hepatic arterial infusion is biliary sclerosis. The current study was undertaken to attempt to modify this toxicity in a canine model that has been demonstrated to closely mimic the clinical situation. Unlike previous studies using this model, in which animals were sacrificed after extensive fibrosis had already occurred, the current experiments were designed so that observations of pathology were made at an earlier time, when the initial inflammatory injury underlying the fibrotic process was still taking place. Implantable pumps were used to deliver FdUrd into the hepatic artery of animals at a rate of 0.3 mg/kg/day in the presence or absence of 10 mg/week dexamethasone or 100 mg/day of celecoxib for 35 days, at which time the animals were beginning to show signs of toxicity. After evaluation for radiological evidence of biliary obstruction, the animals were sacrificed and portions of their livers were processed for examination of microscopic pathology and 2-bromo-5'deoxyuridine labeling index. Dexamethasone treatment protected the animals from biliary sclerosis determined radiologically, further validating this model as being representative of the response in humans. Similarly the Cox-2 inhibitor, celecoxib, appeared to provide protection against radiological changes of biliary stricture, although possibly to a lesser degree than the resultant from dexamethasone. In addition, FdUrd treatment caused elevation of the DNA 2-bromo-5'deoxyuridine labeling index above control levels in biliary epithelial cells. Dexamethasone and celecoxib each significantly attenuated the FdUrd-induced elevation of DNA labeling index in biliary epithelium. These findings demonstrate the usefulness of this canine model for studying the mechanisms of drug-induced biliary sclerosis and reinforce the hypothesis that blocking inflammation may

    Objective: to study risk factors and options for clinical course of acute intestinal obstruction in pregnancy. Materials and methods. A detailed study of history, clinical course, diagnosis and treatment characteristics of acute intestinal obstruction in 79 pregnant women was undertaken. Results: It was determined that a combination of intestinal obstruction, and pregnancy is more common for II and III trimester of gestation (88,5%, with more likely to develop mechanical obstruction caused by the adhesive process (77,2%. Risk factors for intestinal obstruction in pregnancy are: chronic diseases of gastrointestinal tract, surgery of abdominal cavity and pelvis, burdened obstetric and gynecological history and long-term use of progestogens during pregnancy. Difficulties in diagnosis are associated with absence of classical symptoms of disease that is caused by changes in topographical relations of abdominal cavity, increasing size of uterus, as well as lack of immune response to the emergence of a pathological process. Conclusion. Formation of pregnant women at risk for development of intestinal obstruction and preventive measures to address violations of intestinal motor function can reduce the risk of disease. Algorithm of medical tactics for suspected acute intestinal obstruction in pregnancy, allowing to reduce time of diagnosis and provision of medical care.

    Full Text Available Aim: Clinical case of successful two-stage surgical treatment of a 1-year-old child with congenital heart disease and biliary cirrhosis is represented in this article. At the first day of life laparotomy was performed because of high intestinal obstruction. Kasai procedure and Roux-en-Y choledochojejunostomy were per- formed on 12th day and at the end of second month of life, respectively. Liver biopsy showed the signs of biliary cirrhosis. At the same time ventricular septal defect and atrial septal defect with pulmonary hyper- tension were diagnosed. The first step of treatment was the surgical septal defects closure. No complications during procedure, cardiopulmonary bypass and post-operative period were registered. There were no nega- tive effects on liver function after cardiac surgery. 11 months later living-donor liver transplantation was performed without any complications. Patient was discharged at 35th post-transplant day with stable graft function.

    Full Text Available Roux-en-Y hepaticojejunostomy (RYHJ is currently considered as the definitive treatment for iatrogenic bile duct injuries and the principal representative of biliary diversion procedures. This technique has met many milestones of extensive evolution, particularly the last years of concomitant technological evolution (laparoscopic/robotic approach. Anastomotic strictures and leaks, which may have deleterious effects on the survival and quality of life of a patient with biliary obstruction of any cause, made the need of the development of a safe and efficient RYHJ compulsory. The aim of this technical analysis and the juxtaposed discussions is to elucidate with the most important milestones and technical tips and tricks all aspects of a feasible and reliable RYHJ technique that is performed in our center for the last 25 years in around 400 patients.

    Painless obstructive jaundice is often associated with a malignant disease of the common bile duct or head of the pancreas. The authors present a unique case of a 62-year-old woman affected by an intrahepatic cystadenoma that extended into the common biliary duct. To our knowledge no previous case reports have been published on similar cases. After undergoing an en-block hepatic and bile duct resection, this patient is doing well without signs of recurrent disease. PMID:22604197

    To evaluate the feasibility and clinical effectiveness of using a polyurethane-covered expandable nitinol stent in the palliative treatment of malignant duodenal obstruction. Under fluoroscopic guidance, a polyurethane-covered expandable nitinol stent was placed in 12 consecutive patients with malignant duodenal obstructions. All presented with severe nausea and recurrent vomiting. The underlying causes of obstruction were duodenal carcinoma (n=4), pancreatic carcinoma (n=4), gall bladder carcinoma (n=2), distal CBD carcinoma (n=1), and uterine cervical carcinoma (n=1). The sites of obstruction were part I (n=1), part II (n=8), and III (n=3). Due to pre-existing jaundice, eight patients with part II obstructions underwent biliary decompression prior to stent placement. An introducer sheath with a 6-mm outer diameter and stents 16 mm in diameter were employed, and to place the stent, and after-loading technique was used. Stent placement was technically successful in ten patients, and no procedural complications occuured. In one of two patients in whom there was technical failure, and in whom the obstructions were located in part III, the stent was placed transgastrically. Stent migration occurred in one patient four days after the procedure, and treatment involved the palcement of a second, uncovered, nitinol stent. After stent placement, symptoms improved in all patients. During follow-up, obstructive symptoms due to stent stenosis (n=1), colonic obstruction (n=1), and multiple small bowel obstruction (n=1) recurred in three patients. Two of these were treated by placing additional stents in the duodenum and colon, respectively. One of the eight patients in whom a stent was placed in the second portion of the duodenum developed jaundice. The patients died a mean 14 (median, 9) weeks after stent placement. The placement of a polyurethane-covered expandable nitinol stent seems to be technically feasible, safe and effective for the palliative treatment of malignant

    We describe the surgical treatment of a patient with diaphragmatic invasion by a ruptured hepatocellular carcinoma (HCC) associated with biliary and portal venous tumor thrombi. A 67-year-old man was admitted because of jaundice (total serum bilirubin, 6.6 mg/dL). The serum concentration of alpha-fetoprotein was 236.1 ng/mL. The anti-hepatitis C virus antibodies were present in the serum. Computed tomography showed a large hypervascular mass in the right subphrenic region, surrounded by local effusion. Endoscopic retrograde cholangiography revealed dilatation of the left intrahepatic bile duct caused by biliary tumor thrombi extending from the right hepatic duct to the common bile duct. Endoscopic nasobiliary drainage was performed, and the total serum bilirubin level returned to the normal range. Angiography revealed a hypervascular tumor without extravasation of contrast medium in the right lobe and obstruction of the right anterior branch of the portal vein. Right hepatectomy was attempted 15 days after drainage. Severe invasion of the diaphragm by the ruptured HCC was detected. Bleeding of the ruptured HCC stopped spontaneously. Partial resection of the diaphragm was performed, followed by primary suture, without an artificial patch. Tumor thrombectomy was performed from the common bile duct. Macroscopic examination revealed that the ruptured HCC had invaded the diaphragm. Biliary and portal venous tumor thrombi were present. Histopathological examination showed a moderately differentiated HCC with biliary and portal venous tumor thrombi. The postoperative course was uneventful. The patient was discharged on postoperative day 14. Five months after the operation, local and intrahepatic recurrences of HCC were detected. Six months after operation, the patient died of liver failure. In conclusion, the outcome of a patient with diaphragmatic invasion by a ruptured HCC with biliary tumor thrombi was poor, even after curative hepatic resection.

    We report a case of a 56-year-old woman with intrahepatic biliary cystadenoma (IBC) accompanying a tumor embolus in the extrahepatic bile duct, who was admitted to our department on October 13, 2008. Imaging showed an asymmetry dilation of the biliary tree, different bile signals in the biliary tree, a multiloculated lesion and an extrahepatic bile duct lesion with internal septation. A regular left hemihepatectomy en bloc was performed with resection of the entire tumor, during which a tumor embolus protruding into the extrahepatic bile duct and originating from biliary duct of segment 4 was revealed. Microscopically, the multiloculated tumor was confirmed to be a biliary cystadenoma with an epithelial lining composed of biliary-type cuboidal cells and surrounded by an ovarian-like stroma. An aggressive en bloc resection was recommended for the multiloculated lesion. Imaging workup, clinicians and surgeons need to be aware of this different presentation.

    1985-11-01

    Technical problems are repeatedly encountered during percutaneous transhepatic drainage by catheter or endo-prosthesis which are caused by the position, extent and tightness of the stenosis in the biliary ducts. All means of overcoming these problems must be used, otherwise technical failure or complications become inevitable. The methods to be adopted if catheters break and endo-prostheses become displaced or occluded, and for haemorrhage, are described, as well as methods for draining multiple, proximal or intrahepatic stenoses. This is based on an experience with 74 patients on whom 130 drainage procedures have been perforemd (80 catheters, 50 endo-prostheses). All complications and mortality (five patients, 3.8%) were due to problems which could not be solved. Internal biliary drainage by means of an endoprosthesis is markedly superior to catheter drainage. (orig.).

    Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by progressive destruction of the intrahepatic bile ducts, leading to cholestasis. PBC is known to have both hepatic and extrahepatic manifestations. Extrahepatic manifestations are seen in up to 73% of patients with PBC, with the most common being Sjogren’s syndrome, thyroid dysfunction and systemic sclerosis. It is thought that patients with PBC are at increased risk of developing these extrahepatic manifestation...

    2016-04-01

    Full Text Available Background. Functional disorders of the biliary tract (FDBT remain a topical problem of pediatric gastroenterology due to the high incidence and progressive course with formation of chronic cholecystitis and cholelithiasis in patients. Iron deficiency (ID has a well-known effect on the course of the gastrointestinal tract pathology. With the aim of evaluating the state of the biliary system and clinical features of FDBT associated with ID, a case-control study was conducted in 160 children aged 9 to 17 years, who underwent in-patient treatment for exacerbation of biliary tract pathology. According to the iron metabolism tests, children were divided into 3 groups: I — 29 children with FDBT and I degree anemia; II — 91 children with FDBT and latent ID; III — 40 children with FDBT and normal iron metabolism parameters. Research methods included: the study of anamnesis, clinical examination, complete blood count, serum iron level, total iron-binding capacity, calculation of percent transferrin saturation, ultrasound of the abdominal organs and dynamic ultrasound cholecystography with choleretic breakfast. Results. The study found that children with FDBT and ID have a higher incidence of FDBT exacerbations, increased intensity of dyspeptic and asthenovegetative symptoms in case of FDBT exacerbation, increase in size, reduced contractile function of gallbladder (GB and hypotonic-hypokinetic FDBT type. Conclusions. Children with FDBT and ID have burdened course of FDBT due to the high incidence of exacerbations, severe dyspeptic and asthenovegetative symptoms in the acute phase, as well as reduced contractile function of GB and hypotonic-hypokinetic FDBT type, which is clinically unfavorable because of the risk of biliary sludge and cholelithiasis.

    Full Text Available Background. One of the side effects of the third generation cephalosporins is the formation of cephalosporin-induced biliary pseudolithiasis (CIBPL. The purpose of the study was to establish the peculiarities of the formation of biliary sludge during the application of the third generation cephalosporins in the treatment of acute respiratory infections in children. Materials and methods. We examined 46 children aged 2 to 15 years with acute respiratory infections. Сephalosporins were administered intravenously in age doses. We evaluated the biochemical blood test and the echosonography (ultrasound of the biliary tract before the treatment and after the end of antibiotic therapy of all children. Results. According to ultrasound data, in 10 patients (21.7 % with acute respiratory infections, after a course of therapy with the third generation cephalosporins, heterogeneous contents were detected in the gallbladder lumen in the form of a hyperechoic suspension, which indicated the formation of CIBPL. The average age of patients with CIBPL was 9.05 ± 1.44 years and was within the range of 4 to 15 years. We found that in 60 % of the examined children, the formation of CIBPL proceeded subclinically. The results of a biochemical study of blood serum showed that in children with CIBPL, an increase in the activity of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase was observed. It was found that CIBPL is detected in 22.9 % of children against the background of ceftriaxone therapy, in 9 % of patients — ceftazidime. Biliary sludge was formed in 54.5 % of patients receiving ceftriaxone in high doses (100 mg/kg/day, and in 75 % of cases after 10 days of using this antibiotic. Conclusions. The obtained results showed that against the background of using third generation cephalosporins in the treatment of acute respiratory infections, 21.7 % of children had CIBPL. A particularly high risk of developing CIBPL is observed when

    Alternative explanations are common in suspected drug-induced liver injury (DILI) and account for up to 47.1% of analyzed cases. This raised the question of whether a similar frequency may prevail in cases of assumed herb-induced liver injury (HILI). We searched the Medline database for the following terms: herbs, herbal drugs, herbal dietary supplements, hepatotoxic herbs, herbal hepatotoxicity, and herb-induced liver injury. Additional terms specifically addressed single herbs and herbal products: black cohosh, Greater Celandine, green tea, Herbalife products, Hydroxycut, kava, and Pelargonium sidoides. We retrieved 23 published case series and regulatory assessments related to hepatotoxicity by herbs and herbal dietary supplements with alternative causes. The 23 publications comprised 573 cases of initially suspected HILI; alternative causes were evident in 278/573 cases (48.5%). Among them were hepatitis by various viruses (9.7%), autoimmune diseases (10.4%), nonalcoholic and alcoholic liver diseases (5.4%), liver injury by comedication (DILI and other HILI) (43.9%), and liver involvement in infectious diseases (4.7%). Biliary and pancreatic diseases were frequent alternative diagnoses (11.5%), raising therapeutic problems if specific treatment is withheld; pre-existing liver diseases including cirrhosis (9.7%) were additional confounding variables. Other diagnoses were rare, but possibly relevant for the individual patient. In 573 cases of initially assumed HILI, 48.5% showed alternative causes unrelated to the initially incriminated herb, herbal drug, or herbal dietary supplement, calling for thorough clinical evaluations and appropriate causality assessments in future cases of suspected HILI.

    Intrahepatic biliary cystadenoma and biliary cystadenocarcinoma are extremely rare neoplasms of the liver. They share similar radiological characteristics, and the clinicopathological features are poorly defined. We aim to provide an algorithm for preoperative differentiation of the two diseases. Patients who underwent liver resection between May 2001 and May 2011 at Peking Union Medical College Hospital with biliary cystadenoma (20 cases) and biliary cystadenocarcinoma (10 cases) were reviewed. Significant differences were shown in age (P=0.030), gender (P=0.002) and symptom duration (P=0.012). Most biliary cystadenomas occurred in women ≤60 years old (85%), whilst most biliary cystadenocarcinomas occurred in older males (50%). Shorter symptom duration indicated a higher risk of biliary cystadenocarcinoma. Arterial blood flow and wall/nodule enhancement tended to be more common in biliary cystadenocarcinoma, but the difference was not significant (P=0.348). A score system was developed. The case-by-case validation and leave-one-out cross-validation showed an accuracy of 95.5% and 90.9%, respectively. The discriminative accuracy for cases from another hospital during the same period was 90.9%. Older age, male gender, and shorter symptom duration are associated with higher possibility of biliary cystadenocarcinoma. Location and blood supply by radiology might be instrumental but still need further verification. Copyright © 2011 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

  7. Obstructive sleep apnea

    2011-11-01

    Full Text Available Obstructive sleep apnea (OSA affects millions of Americans and is estimated to be as prevalent as asthma and diabetes. Given the fact that obesity is a major risk factor for OSA, and given the current global rise in obesity, the prevalence of OSA will increase in the future. Individuals with sleep apnea are often unaware of their sleep disorder. It is usually first recognized as a problem by family members who witness the apneic episodes or is suspected by their primary care doctor because of the individual’s risk factors and symptoms. The vast majority remain undiagnosed and untreated, despite the fact that this serious disorder can have significant consequences. Individuals with untreated OSA can stop breathing hundreds of times a night during their sleep. These apneic events can lead to fragmented sleep that is of poor quality, as the brain arouses briefly in order for the body to resume breathing. Untreated, sleep apnea can have dire health consequences and can increase the risk of hypertension, diabetes, heart disease, and heart failure. OSA management has also become important in a number of comorbid neurological conditions, including epilepsy, stroke, multiple sclerosis, and headache. Diagnosis typically involves use of screening questionnaires, physical exam, and an overnight polysomnography or a portable home study. Treatment options include changes in lifestyle, positive airway pressure, surgery, and dental appliances.

    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.

    Little is known about risk factors for biliary pancreatitis in children. Objectives We characterized cases of pediatric biliary pancreatitis, compared biliary with non-biliary cases, examined differences in presentation between younger and older children, and studied features distinguishing gallstone- from sludge-induced pancreatitis. Methods We evaluated 76 episodes of biliary pancreatitis from 271 cases of acute pancreatitis in children admitted to a tertiary care hospital from 1994 to 2007. Results Of the 76 cases, 55% had gallstones, 21% had sludge, and 24% had structural defects. Hispanic children had a 2.85 (p=0.01) and 5.59 (p=0.003) higher probability for biliary pancreatitis than white and black children, respectively. Median serum amylase and lipase in children with biliary pancreatitis were 64% and 49% higher, respectively, compared to other etiologies (ppancreatitis (OR=6.69, p=0.001). When comparing gallstone- with sludge-induced etiologies, obesity was an independent predictor (38% more prevalent, ppancreatitis over other etiologies. Furthermore, obesity can distinguish gallstone- from sludge-induced pancreatitis. These findings may spur prospective studies to determine the optimal evaluation and management of children with biliary pancreatitis. PMID:22002481

    The purpose of this study was to assess the value of adding a T1-weighted image to MR cholangiopancreatography (MRCP) to detect bile duct stones. During a 30-month period, 148 patients suspected of having biliary stones and who underwent MRI including MRCP, a fat-suppressed T1-weighted fast low-angle shot (FLASH) sequence, and an axial HASTE sequence were enrolled in this study. The biliary stones were confirmed by ERCP, surgery, and percutaneous transhepatic cholangiography. Of these 148 patients, 73 had extrahepatic stones, 45 had intrahepatic stones, 20 had both extrahepatic and intrahepatic stones, and 10 had no biliary stones. Two separate sets of images, the MRCP set (composed of MRCP and axial HASTE) and the combined interpretion of the MRCP set and the T1-weighted image, were analyzed independently and separately by two observers. The diagnostic accuracy was evaluated using the receiver operating characteristic method. The sensitivity and specificity were also calculated. For common duct stones, the diagnostic accuracy and the sensitivity of both image sets showed similar values without any significant difference (0.998 [97.8%] for the combined interpretation; 0.988 [97.8%] for observer 1 and 0.995 [96.8%] for observer 2 for the MRCP set). However, for the intrahepatic stones, the diagnostic accuracy (0.993) and the sensitivity (98.5%) of the combined interpretation were significantly higher than those of the MRCP set for the two observers (0.926 [83.8%] for observer 1 and 0.922 [85.3%] for observer 2) (p axial T1-weighted image with MRCP is valuable for detecting intrahepatic stones.

    Biliary atresia (BA) causes biliary obstruction in neonates. Although the Kasai operation can successfully treat certain BA cases, many patients exhibit recurrent jaundice and secondary biliary cirrhosis requiring liver transplantation. Consequently, studies of the prognostic factors of the Kasai operation are needed. Accordingly, sonic hedgehog (SHH) pathway expression at the extrahepatic bile duct (EHBD), an important bile duct repair mechanism, will be investigated via immunohistochemistry in patients with BA to examine the association with post-Kasai operation prognosis. Fifty-seven EHBD specimens were obtained during Kasai operations from 1992 to 2009. The SHH, patched (PTCH), and glioblastoma-2 (Gli-2) immunohistochemical staining results were analyzed quantitatively. Overall, 57.9% of patients had bile flow normalization after the Kasai operation; 43.1% did not. High preoperative serum total bilirubin, direct bilirubin, and aspartate aminotransferase levels were associated with sustained jaundice post-Kasai operation, as was an age ≥65days at the time of surgery (all pjaundice relapse. Strong Gli-2 and SHH expression in the EHBD might be a poor prognostic factor in Kasai operation-treated patients with BA. Copyright © 2015 Elsevier Inc. All rights reserved.

    2008-06-01

    There is a subset of patients who have biochemical and histologic features consistent with primary biliary cirrhosis (PBC) who lack antimitochondrial antibodies (AMA). This entity is usually referred to as AMA-negative PBC or alternatively autoimmune cholangitis. Patients who have AMA-negative PBC are believed to have a similar clinical course, response to treatment, and prognosis as their AMA-positive counterparts. As more sensitive and specific serologic tests are developed to detect serum AMA, it is possible we may find that these patients initially believed to be AMA-negative are indeed AMA-positive, suggesting a single disease process.

    CREST syndrome, a relatively benign, slowly progressive variant of systemic scleroderma consists of calcinosis, Raynaud's phenomenon, esophageal dysfunction, sclerodactyly, and telangiectasia. Although the association of this syndrome with primary biliary cirrhosis (PBC) is recognized in women, it has never been described in a man. We report the rare case of a male patient with CREST syndrome accompanied by PBC, manifested by acute cholecystitis and mild jaundice. The association of the two conditions is clinically and etiologically important. Clinicians must be aware of this association, sincethe clinical features of CREST syndrome may be mild and may be thought to be complications of the underlying liver disease.

    Full Text Available Ascariasis is a common infection in many developing countries. The prevalence of ascariasis is related to poverty, poor hygienic and sanitary conditions. The adult form of Ascaris lumbricoides usually resides in the human intestinal lumen (more frequently in the jejunum and middle ileum and does not cause symptoms. However, it can occasionally cause severe complications such as intestinal obstruction or perforation peritonitis. Its migration into the biliary tract is not uncommon but gallbladder involvement is very rare. Abdominal ultrasonography is essential to detect the presence of this parasite. In this article, we describe the radiologic findings, clinical manifestations and successful medical treatment of a patient with gallbladder ascariasis diagnosed in an emergency setting.

    The origin of bile duct-like cells (oval cells) proliferating during chemical hepatocarcinogenesis is highly controversial. To illuminate this issue, we induced oval cell proliferation by feeding rats a choline-devoid diet containing 0.1% ethionine (CDE), a hepatocarcinogenic diet, for up to 60 days. At various times we studied 1) oval cell morphology by light and electron microscopy, 2) the immunohistochemical expression of albumin and intermediate filament proteins by the various hepatic cells, 3) hepatic incorporation of [3H]thymidine by histoautoradiography, 4) the fractional area occupied by duct-like structures in liver cross sections, 5) the biliary tree volume in vivo to establish the possible continuity of the proliferated structures to the existing biliary lumina, and 6) spontaneous bile flow rate and the choleretic responsiveness to the hormone secretin, which stimulates ductular secretory activity. The results demonstrated the following: 1) oval cells resemble bile duct cells with respect to their histologic and ultrastructural appearance and their formation of duct-like structures; 2) as normal and hyperplastic bile duct cells induced by bile duct ligation, oval cells are positive for cytokeratins 7 and 19 (markers of glandular epithelia) and 8 and 18 (markers of simple epithelia) and are negative for vimentin and desmin, markers of mesenchymal and muscular differentiation, respectively; 3) in general, oval cells are negative for albumin, which is expressive of hepatocyte lineage, even though a few are positive for this protein, particularly those morphologically resembling small hepatocytes; 4) after initiation of the CDE diet, DNA synthesis begins in biliary epithelial cells; and 5) the degree of oval cell proliferation parallels the increase in biliary tree volume, spontaneous bile flow rate, and responsiveness to secretin choleresis, as in bile duct cell hyperplasia induced by biliary obstruction.

    Until recently, biliary lithiasis was considered infrequent in childhood. According to their composition, gallstones can be classified into cholesterol stones and pigment stones. The latter are mainly composed of calcium salts of unconjugated bilirubin and are divided into hard black and soft brown stones. In children, up to 75 % of gallstones are pigment stones. Their etiology is often unknown. Biliary lithiasis in children differs from that in adults and there is very little scientific evidence on the most suitable therapeutic procedures. Symptom-free stones usually have a benign course and do not require medical or surgical treatment. Symptoms are often nonspecific and include dyspepsia and chronic abdominal pain. These symptoms are an indication for ultrasonographic scan to rule out the presence of gallstones. Cholecystectomy is the definitive treatment for gallstones but is not always indicated. Medical treatment with ursodeoxycholic acid is indicated in oligosymptomatic and asymptomatic lithiasis with transparent, soft, cholesterol-rich stones and a functional bladder and in patients with a high surgical risk.

    Biliary atresia is an idiopathic, neonatal liver disease of the bile ducts. The natural evolution of biliary atresia is known in developed countries. This study describes the clinical course of biliary atresia in Vietnam, a developing country. Chart reviews were undertaken of patients treated with or without the Kasai procedure between January 2010 and July 2013 at a children's hospital in Vietnam. Of 287 children with biliary atresia, 149 (52%) were treated without the Kasai procedure and 138 (48%) were treated with the Kasai procedure. Median age at diagnosis was 2.4 months for children treated without the Kasai procedure vs 2.3 months for those treated with the procedure. The percentages of patients in the group treated without the Kasai procedure presenting at 6 months of age were 31%, 35%, 15%, 10%, and 9%, respectively, compared to those treated with the Kasai procedure at 36% (P = .38), 44% (P = .12), 16% (P = 1.0), 4% (P = .037), and 0% (P Vietnam. The majority of biliary atresia in Vietnam remains untreated despite early presentation and reasonable outcomes after a Kasai procedure relative to Western countries. These data illustrate the high health care burden for biliary atresia in Vietnam and the need to improve education about biliary atresia and its treatment. Copyright © 2016 Elsevier Inc.

    Yttrium-90 (90Y) radioembolization has emerged as a promising and safe therapeutic modality for patients with hepatocellular carcinoma (HCC) or metastatic liver cancer. The present report describes biliary sequelae following intraarterial 90Y therapy in patients with HCC or liver metastases. All patients were treated with 90Y therapy according to standard lobar treatment protocol. Pre- and posttreatment imaging, liver function tests, and serum total bilirubin measurements were performed. Three to 6 months after treatment, biliary sequelae were evaluated with computed tomography and magnetic resonance imaging, and any liver-related laboratory adverse events were noted. A total of 327 patients (HCC, n=190; liver metastases, n=137) received 569 infusions of 90Y. At follow-up imaging, 33 patients (10.1%; liver metastases, n=26; HCC, n=7) had 40 imaging findings related to the biliary tree, including biliary necrosis (n=17), biloma (n=3), cholecystitis (n=2), gallbladder wall enhancement (n=6), gallbladder wall rent (n=3), abscess (n=1), and stricture (n=8). A total of 31 patients exhibited grade 3/4 bilirubin toxicities (13 [6.8%] with HCC, 18 [13.1%] with liver metastases). Unplanned interventions prompted by biliary sequelae were necessary in six of 327 patients (1.8%). 90Y therapy in patients with HCC or metastatic disease to the liver is associated with an acceptable rate of biliary toxicities. Further studies assessing long-term biliary sequelae are warranted.

    Biliary strictures are the most common biliary tract complication after liver transplantation. There are scarce data on the results of hepaticojejunostomy (HJ) in the management of biliary complications after orthotopic liver transplantation (OLT). Thus, the role of surgery in this setting remains to be established. The aim of this study was to evaluate the results of surgical treatment of patients with biliary complications at our institution. We reviewed 1000 consecutive liver transplantations performed at our institution from 1984 to 2007. We used a prospectively recorded database to identify patients who underwent HJ to treat any biliary tract complication. Overall, 62 patients (6.2%) underwent HJ, 40 for an anastomotic and 7 for a non-anastomotic stricture as well as 15 for biliary leaks. Postoperative morbidity was 16%, and postoperative mortality 1.6%. There were 7 cases of anastomotic stenosis (11.3%). Four patients (5%) required retransplantation. HJ is a safe procedure to manage biliary complications after OLT. It may be the first treatment choice especially for cases with anastomotic strictures. Copyright © 2012 Elsevier Inc.

    To present the findings of intestinal obstruction and evaluate the value of CT in the diagnosis of intestinal obstruction. We prospectively analyzed CT scans of twenty-two patients who were suspected to have intestinal obstruction. All 22 patients were confirmed with surgery: 10 patients with adhesion, four with primary tumor, one with metastatic intestinal tumor, two with inflammatory bowel disease, two with intussusception, two with extrinsic compression by ovarian tumor, and one with inguinal hernia. The CT scans were evaluated with special attention to their causes, locations, and CT findings and intestinal obstruction. CT diagnosis and findings were compared with surgical results. Their causes were diagnosed correctly on CT scans in seventeen of 22 cases(77.3%). Locations of the intestinal obstruction were diagnosis correctly in 16 cases(72.7%). The CT findings intestinal obstruction were categorized into dilated proximal bowel loops with normal distal loops, thickening of the affected bowel wall, presence of the transitional zone, and no detectable abnormalities. The associated extraluminal findings were fat infiltration around the dilated bowel loops, ascites, and mesenteric lymph nodes enlargement. There were two limitations of CT in our study: first, no detectable difference between jejunum and ileum on CT scans, and second, difficulty in differential diagnosis between thickened bowel wall mimicking normal non-dilated segment and mechanical obstruction from tumors or inflammatory bowel diseases. We conclude that CT is useful method in the evaluation of causes and locations of intestinal obstruction and the demonstration of the associated extraluminal abnormalities.

    We have studied the biliary excretion of (/sup 14/C) omeprazole in humans. The study was performed in eight healthy subjects and the technique used was based on multiple marker dilution principles with double-lumen tubes placed in both the stomach and intestine. The results obtained show a 16% biliary excretion of (/sup 14/C) omeprazole. These data suggest a minimal spillover of omeprazole from the gastric mucosa into the gastric lumen in humans. The results also agree with previous data of the fecal recovery of radiolabeled omeprazole that suggest that the fecal excretion of intravenous omeprazole in humans is entirely accounted for by biliary excretion.

    Interventional endoscopic ultrasonography (EUS) based on EUS-guided fine-needle aspiration has rapidly spread as a minimally invasive procedure. Especially in patients with failed endoscopic retrograde cholangiopancreatography, EUS-guided biliary intervention is reported to be useful as salvage therapy. EUS-guided biliary interventions are carried out using three techniques: EUS-guided bilioenteric anastomosis, EUS-guided rendezvous procedure, and EUS-guided antegrade treatment. Although interventional EUS is not yet a standardized procedure, there have been recent advances in this field that address various biliary diseases. Here, we summarize the indications, techniques, clinical results of previous studies, and future perspectives. PMID:26327757

    Full Text Available 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.

    Biliary atresia is a chronic cholangiopathy leading to progressive fibrosis of both intra- and extrahepatic bile ducts. The cause of the condition is unknown. Fundamental management of biliary atresia is surgical intervention and the outcomes of the treatment depend on the child's age with best results when performed within the first 2 months of life. Thus, the main role of pediatric healthcare is an urgent differential diagnosis and prompt qualification for the surgery, optimal postoperative management and early qualification for the liver transplantation in patients with persistent cholestasis. The authors discuss the clinical presentation, diagnosis and management of biliary atresia.

    We evaluated the efficacy of ureteroscopic therapy (electrohydraulic lithotripsy [EHL] and intraductal laser lithotripsy [ILL]) in patients with challenging biliary stones secondary to anatomic variations resulting from a previous surgical procedure, including liver transplantation. A retrospective chart review was performed for all patients with previous surgical alteration of the gastrointestinal (GI) tract who underwent EHL or ILL via peroral or percutaneous access for choledocholithiasis by a single surgeon at our institution from 2000 to 2012. A database containing clinical and surgical variables was created, and long-term follow-up was conducted (3-138 months; median, 99 months). Thirteen patients (51.7±20.0 years; M:F, 10:3) in whom endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTHC), or both failed were identified. Failure of ERCP/PTHC was because of inaccessibility of the calculi in all cases. Stone clearance was achieved in 12/13 (93%) patients; 8/12 (62%) after one procedure, and 4/12 (31%) after two procedures. One patient with biliary cast syndrome needed four interventions over 9 years. Major complications were low, with only one patient with hypotension and cholangitis that resolved with 24 hours of administration of intravenous fluids and antibiotics. Both endoscopic and percutaneous lithotripsies are effective treatments for refractory biliary calculi resulting from the post-surgical GI tract. Although a staged second procedure may be necessary in patients with significant stone burden, this is significantly better than extensive open surgery.

Neonates and patients with duodenal obstruction were excluded from the study. The CT findings were analyzed for the location of obstruction site, abnormalities of the mesentery and mesenteric vessels, bowel wall thickening, closed loop obstruction, and strangulation. The obstruction site was divided into five parts. The preoperative CT diagnosis was compared with the final diagnosis. Causes of small bowel obstruction were intussusception (n = 6), appendiceal perforation (n = 4), transmesenteric internal hernia (n = 2), postoperative bands (n = 1), idiopathic multiple bands (n = 1), a foreign body (n = 1), a small bowel adenocarcinoma (n = 1), Meckel's diverticulitis (n = 1), tuberculous peritonitis (n = 1) and Salmonella enteritis with bowel perforation (n = 1). The CT findings showed mesenteric vascular prominence (n = 13), omental or mesenteric infiltration (n = 10), localized bowel wall thickening (n = 7) closed loops obstruction (n = 3) and strangulation (n = 1). The obstruction site was identified in all cases. The causes of obstruction could be diagnosed preoperatively in 14 cases, but a preoperative diagnosis was difficult in 5 cases. The causes of small bowel obstruction in children are variable, and CT is useful for evaluating the cause and localization of small bowel obstruction.

    Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by progressive destruction of the intrahepatic bile ducts, leading to cholestasis. PBC is known to have both hepatic and extrahepatic manifestations. Extrahepatic manifestations are seen in up to 73% of patients with PBC, with the most common being Sjogren's syndrome, thyroid dysfunction and systemic sclerosis. It is thought that patients with PBC are at increased risk of developing these extrahepatic manifestations, almost all of which are autoimmune, because patients with autoimmune disease are at higher risk of developing another autoimmune condition. Due to the high prevalence of extrahepatic diseases in patients with PBC, it is important to complete a thorough medical history at the time of diagnosis. Prompt recognition of extrahepatic disease can lead to improved patient outcomes and quality of life. The following review summarizes the most common extrahepatic conditions associated with PBC.

  1. Novel therapeutic targets for primary biliary cholangitis

    Full Text Available Primary biliary cholangitis (PBC is a chronic autoimmune-mediated liver disease manifesting as progressive cholestasis and non-purulent inflammation in small- and medium-sized intrahepatic bile ducts. It finally progresses to liver cirrhosis and liver cancer and greatly threatens patient's life. Studies have found that ursodeoxycholic acid (UDCA can treat PBC effectively. There is a constant increase in the proportion of patients with poor response to UDCA who have undergone transplantation or died, and therefore, new therapeutic regimens should be developed as soon as possible. It is necessary to develop new drugs which act on the key processes of disease progression, such as the "upstream" immune response, the "midstream" bile duct injury, and the "downstream" fibrotic process. Combination treatment with drugs targeting different pathways is a trend for future development. This article summarizes current potential therapeutic regimens for PBC and assesses the challenges in the treatment of PBC.

    Pruritus is a major symptom of primary biliary cirrhosis, cholestatic autoimmune disease which affects mostly middle-age women. Often, it can be severe and refractory to multiple treatments, and mostly affecting the patient’s health-related quality of life. Intense pruritus can be itself an indication to liver transplantation, in extreme cases leading to suicide. Its physiopathology has not yet been fully elucidated, but recent studies added the elevation of autotaxin and lysophosphatidic acid to the group of classic mechanisms already linked to cholestatic pruritus. In this case report we illustrate how ultraviolet B phototherapy appears to successfully control severe pruritus and contribute to the healing of pruritic skin lesions caused by intense scratching. There is limited medical literature concerning this therapeutic approach on cholestatic pruritus, but we hope that further randomised controlled trials will successfully establish it as an effective treatment in the near future.

    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.

    1979-01-01

    The Authors report 180 cases of transdudenal papillosphincterotomy. Medium follow-up at 5 years revealed a complete recovery in 87 of 100 controlled patients. Nine cases revealed persistence of some degree of dyspepsia, while a second operation was necessary for the remaining patients to remove recurrent calculi in 2 cases and because of Oddi's stenosis in other two cases. A 4,4% mortality operative was observed, following postoperative pancreatitis in 1,1%, duodenal fistula or haemorrhage in 1,6%, and 1,6% from other causes. On the basis of their results the Authors conclude that transduodenal papillosphincterotomy is an effective procedure in treating complicated lithiasic biliary disease when respecting the reported indications.

    Aim: To evaluate the 3 T MR cholangiopancreatography (MRCP) appearances of biliary ascariasis. Materials and methods: Nine patients with a MRCP diagnosis of biliary ascariasis were reviewed. All patients had endoscopic retrograde cholangiopancreatography (ERCP) or surgical confirmation of the disease. Results: On thin-slab MRCP imaging, Ascaris worms are clearly demarcated within the biliary tree. All the identified worms demonstrated a characteristic three-parallel-lines appearance. The middle high-signal intensity line is sandwiched between two low-signal intensity lines and they are in turn surrounded by high signal bile. On thick-slab MRCP the worms also show the three-line sign but with less clarity. However, thick-slab MRCP has the advantage of providing three-dimensional ERCP-like images of the pancreaticobiliary system. Conclusion: The 'three-line' sign appears to be a characteristic sign of biliary ascariasis on 3 T MRCP.

  12. Functional diagnosis of biliary drainage endoprosthesis by hepatobiliary scintigraphy

    Ranner, G.; Lammer, J.; Fueger, G.F.; Posch, E.; Hausegger, K.A.

    1988-11-01

    In 11 patients with biliary endoprosthesis, hepatobiliary scintigraphy with dimethyliminodiacetic acid (HIDA) was performed 16 times because of an increased in the serum bilirubin level. For the demonstration of dysfunction of the endoprosthesis, this method proved to have the same sensitivity as transhepatic cholangiography, which was performed as control examination. Therefore, hepatobiliary scintigraphy, a noninvasive and well-tolerated examination, can be recommended as a primary diagnostic tool in addition to ultrasonography for assessment of the drainage function of the biliary endoprosthesis.

    M. Crespi

    2016-01-01

    Full Text Available 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.

    Biliary complications after liver transplantation (LT) are common. This study aimed to ascertain the value of gadoxetic acid-enhanced T1-weighted (T1w) magnetic resonance cholangiography (MRC) to evaluate anastomotic strictures (AS), non-anastomotic strictures (NAS) and biliary casts (BC). Sixty liver-transplanted patients with suspicion of biliary complications and T2w-MRCP and T1w-MRC followed by endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography (PTC) were analysed. Two readers reviewed the MRCs and rated image quality (IQ) and likelihood for AS/NAS/BC on Likert scales. Sensitivity, specificity and predictive values were calculated, ROC curve analysis performed, and inter-reader variability assessed. The subjective added value of T1w-MRC was rated. IQ was high for all sequences without significant differences (2.83-2.88). In 39 patients ERCP/PTC detected a complication. Sensitivity and specificity for AS were 64-96 using T2w-MRCP, increasing to 79-100 using all sequences. Use of all sequences increased the sensitivity of detecting NAS/BC from 72-92% to 88-100% and 67-89% to 72-94%, respectively. Kappa values were substantial (0.45-0.62). T1w-MRC was found to be helpful in 75-83.3%. Combining T1w-MRC and T2w-MRCP increased sensitivity and specificity and diagnostic confidence in patients after LT with suspected biliary complications. T1w-MRC is a valuable tool for evaluating post-transplant biliary complications. (orig.)

    Cholangitis arising from biliary infection dominates the prognosis in Caroli's disease. To clarify the influences of bacterial infection on the biliary cystogenesis, in vivo and in vitro studies were performed using the polycystic kidney (PCK) rat as an animal model of Caroli's disease. Cholangitis became a frequent histological finding in aged PCK rats, and neovascularization around the bile ducts also increased in aged PCK rats. Immunohistochemistry revealed that expression of vascular endothelial growth factor (VEGF) was increased in PCK rat biliary epithelium. In vitro, PCK cholangiocytes overexpressed VEGF, and the supernatant of cultured PCK cholangiocytes significantly increased the proliferative activity, migration, and tube formation of cultured rat vascular endothelial cells. Stimulation with lipopolysaccharide (LPS) further induced VEGF expression in PCK cholangiocytes, which might be mediated by signaling pathways involving phosphatidylinositol 3-kinase (PI3K)-Akt and c-Jun N-terminal kinase (JNK). Both LPS and VEGF increased cell proliferative activity in PCK cholangiocytes, and siRNA against VEGF significantly reduced LPS-induced cell proliferation. Thus, LPS-induced overexpression of VEGF in the biliary epithelium may lead to hypervascularity around the bile ducts; concurrently, LPS and VEGF act as cell proliferation factors for cholangiocytes. Biliary infection may thus exacerbate biliary cystogenesis in PCK rats. PMID:22015458

    A group of 32 Friesian and four Hereford calves, 3-4 months old with body weights between 100-120 kg, were purchased from a weaner sale. On arrival at the property the Hereford calves were treated with a combination anthelmintic containing 2 g/L abamectin and 80 g/L levamisole hydrochloride. Shortly afterwards they developed tremors and frothing from the mouth, and two died overnight. The Friesian calves were treated with the same anthelmintic on the following day, when some showed hypersalivation and frothing from the mouth. Examination of the three most severely affected Friesian calves revealed severe nicotinic-type symptoms including hypersalivation, frothing from the mouth, muscle tremors, recumbency, rapid respiration, hyperaesthesia, and central nervous system depression. Other calves showed mild to moderate signs of intoxication including restlessness, tail switching, salivation, tremors, frequent defaecation, mild colic and jaw chomping. Two calves died shortly afterwards. An adverse drug event investigation revealed that the formulation and quality of the anthelmintic was within the correct specification, and that the drench gun was functioning correctly. Suspected levamisole intoxication due to a combination of possible overdosing, dehydration, and stress caused by transportation and prolonged yarding. Susceptibility to levamisole toxicity in New Zealand calves can be increased if factors like dehydration or stress are present. Levamisole has a narrow margin of safety, and overdosing in calves can easily occur if the dose rate is not based on their actual weight or health status.

    Full Text Available Purpose. In the last 10 years in the treatment of acute jaundice, developed on a background of malignant tumors of the pancreatobiliary zone (PBZ, more preferred method is endoscopic retrograde biliary drainage.Material and methods. From January 2007 to July 2012 in the clinic of hospital surgery N. 2 PRNMU endoscopic biliary stenting was performed in 441 patients. Of these, 324 (73.5% stenting fell to 234 patients with a tumor of the extrahepatic bile ducts. The diagnostic program included ultrasonography, computed tomography, endoscopic ultrasonography and endoscopic retrograde cholangiopancreaticography.Results. Installing of bilioduodenal stent in 223 patients (95.3% was generated after the pre-endoscopic papillosphincterotomy (EPST. The adequacy of the biliary drainage after produced in the required amount of biliary stent placement was achieved in all patients. In 46 cases, execute the biliary tract prosthesis failed. Complications of endoscopic interventions presented with acute pancreatitis, cholangitis, bleeding from the area of EPST, perforated duodenal wall and migration of the stent were in 19 cases (5?9%. Postoperative mortality was 3?8%. 7 patients (3% died after the endoscopic decompression of the biliary tract. After stenting in all patients with jaundice it was resolved or significantly reduced. In 185 of them (79% was the definitive guide endoscopic treatment because of severity of tumor process. In cases of jaundice reccurence endoscopic stent recanalizing or replacement were performed. In the remaining cases (21% patients after the resolution of jaundice decompressive surgical intervention were done.Conclusion. The method of endoscopic retrograde biliary drainage allows you to prepare patients with obstructive jaundice for surgical intervention, including the radical. The frequency of complications after endoscopic retrograde operations on the major duodenal papilla for acute jaundice blastomatous origin did not differ from

    Twenty percent of cholecystectomies in the US are performed for a diagnosis of biliary dyskinesia. Diagnosis is made by measuring gallbladder ejection fraction (GbEF) using hepatobiliary scintigraphy. Our purpose was to evaluate the reproducibility of GbEF measurements. This is a retrospective review of patients referred for cholecystectomy, from 2010 to 2016, with a diagnosis of biliary dyskinesia based on a GbEF test, who then underwent a repeat GbEF test. Thirty consecutive patients were identified by hospital records. Re-testing of GbEF was performed at least 6 weeks after the initial test using Tc-99m and slow injection of sincalide at 0.02 mcg/kg. On re-testing, 16 of 30 patients (53%) patients had a normal GbEF of >35%, ie the initial test result was not reproducible in them. Age, sex, days between testing, and initial GbEF did not differ between groups. The 14 patients who re-tested positive for biliary dyskinesia with reduced GbEF were significantly more likely to have episodic pain than steady pain. Re-testing frequently resulted in change in management in that most patients who re-tested in the normal range were not offered cholecystectomy. Hepatobiliary scintigraphy with GbEF is a poorly reproducible test. Re-testing resulted in a change in management in many patients who then avoided cholecystectomy. Strong consideration should be given to repeating hepatobiliary scintigraphy with GbEF before cholecystectomy in patients with an initial positive test. Copyright © 2017 American College of Surgeons.

    Background Hepato-biliary tract lithiasis is common and present either as pain or as asymptomatic on abdominal ultrasonography for other causes. Although the DNA of Helicobacter species are identified in the gallbladder bile, tissue or stones analyzed from these cases, still a causal relationship could not be established due to different results from different geographical parts. Methods A detailed search of pubmed and pubmedcentral was carried out with key words Helicobacter and gallbladder, gallstones, hepaticolithiasis, cholelithiasis and choledocholithiasis, benign biliary diseases, liver diseases. The data was entered in a data base and meta analysis was carried out. The analysis was carried out using odds ratio and a fixed effect model, 95% confidence intervals for odds ratio was calculated. Chi square test for heterogeneity was employed. The overall effect was calculated using Z test. Results A total of 12 articles were identified. One study used IgG for diagnosis while others used the PCR for Ure A gene, 16 S RNA or Cag A genes. A couple of studies used culture or histopathology besides the PCR. The cumulative results show a higher association of Helicobacter with chronic liver diseases (30.48%), and stone diseases (42.96%)(OR 1.77 95% CI 1.2–2.58; Z = 2.94, p = 0.003), the effect of each could not be identified as it was difficult to isolate the effect of helicobacter due to mixing of cases in each study. Conclusion The results of present meta analysis shows that there is a slight higher risk of cholelithiasis and benign liver disease (OR 1.77), however due to inherent inability to isolate the effect of stone disease from that of other benign lesions it is not possible to say for sure that Helicobacter has a casual relationship with benign biliary disease or stone disease or both.

    Full Text Available Background: The aim of this study was to evaluate epidemiological relationship between chronic obstructive pulmonary disease and sleep apnea syndrome in a sample of Persian population. Methods: As a part of a population-based cross-sectional study, 3900 randomly selected individuals aged 15 years or older were invited to take part in the survey; 3770 individuals (96.6% agreed to fill out the respiratory and sleep questionnaire. Those subjects suspected to have either chronic obstructive pulmonary disease and/or obstructive sleep apnea underwent spirometry and polysomnography test if indicated. Spirometric measurements were performed on 420 invited responders. Polysomnography measurements were performed on 25 of the responders. Results: Prevalence rates for sleep apnea, chronic obstructive pulmonary disease and current asthma were 4.98%, 5.7% and 3.1%, respectively. Logistic regression showed independent associations between sleep apnea and chronic obstructive pulmonary disease. There was no significant independent association between sleep apnea symptoms and current asthma and wheeze ever. Conclusions: These observations indicated relationship between chronic obstructive pulmonary disease and obstructive sleep apnea. These observations indicated the necessity of further studies to explain the possible common pathogenic mechanisms involved in two disease entities.

    Extrahepatic portal vein obstruction (EHPVO) is a primary vascular condition characterized by chronic long standing blockage and cavernous transformation of portal vein with or without additional involvement of intrahepatic branches, splenic or superior mesenteric vein. Patients generally present in childhood with multiple episodes of variceal bleed and EHPVO is the predominant cause of paediatric portal hypertension (PHT) in developing countries. It is a pre-hepatic type of PHT in which liver functions and morphology are preserved till late. Characteristic imaging findings include multiple parabiliary venous collaterals which form to bypass the obstructed portal vein with resultant changes in biliary tree termed portal biliopathy or portal cavernoma cholangiopathy. Ultrasound with Doppler, computed tomography, magnetic resonance cholangiography and magnetic resonance portovenography are non-invasive techniques which can provide a comprehensive analysis of degree and extent of EHPVO, collaterals and bile duct abnormalities. These can also be used to assess in surgical planning as well screening for shunt patency in post-operative patients. The multitude of changes and complications seen in EHPVO can be addressed by various radiological interventional procedures. The myriad of symptoms arising secondary to vascular, biliary, visceral and neurocognitive changes in EHPVO can be managed by various radiological interventions like transjugular intra-hepatic portosystemic shunt, percutaneous transhepatic biliary drainage, partial splenic embolization, balloon occluded retrograde obliteration of portosystemic shunt (PSS) and revision of PSS.

    Introduction Patients with metastatic colorectal cancer can develop jaundice from intrahepatic or extrahepatic causes. Currently, there is little data on the underlying causes and overall survival after onset of jaundice. The purpose of this study was to characterize the causes of jaundice and determine outcomes. Methods Six hundred twenty-nine patients treated for metastatic colorectal cancer between 2004 and 2010 were retrospectively reviewed. Those developing jaundice were grouped as having intrahepatic or extrahepatic obstruction. Demographics, clinicopathologic, and outcome data were analyzed. Results Sixty-two patients with metastatic colorectal cancer developed jaundice. Intrahepatic biliary obstruction was most common, occurring in younger patients. Time from metastatic diagnosis to presentation of jaundice was similar between groups, as was the mean number of prior lines of chemotherapy. Biliary decompression was successful 41.7 % of the time and was attempted more commonly for extrahepatic causes. Median overall survival after onset of jaundice was 1.5 months and it was similar between groups, but improved to 9.6 months in patients who were able to receive further chemotherapy. Conclusions Jaundice due to metastatic colorectal cancer is an ominous finding, representing aggressive tumor biology or exhaustion of therapies. Biliary decompression is often difficult and should only be pursued when additional treatment options are available. PMID:25300799

  17. Biliary cystadenoma: short- and long-term outcome after radical hepatic resection.

    The intrahepatic biliary cystadenoma is a rare benign tumor of the liver, originating from an intrahepatic bile duct: it becomes symptomatic only when it causes obstruction of the bile duct itself. Regardless of the various diagnostic modalities available, it is difficult to distinguish preoperatively the cystadenoma both from a simple liver cyst, and from a cystic carcinoma of the bile duct. An incomplete surgical removal of the cyst often results in a higher risk of size increase and recurrence, even considering that the lesion may degenerate into a cystadenocarcinoma. Between January 2004 and May 2011, 1,173 liver resections were carried out at the Hepatobiliary Surgery Unit of San Raffaele Hospital: 12 of these were performed for cystadenoma. Forty-six patients underwent laparoscopic liver cysts deroofing: definitive histological examination in six of these patients revealed instead the diagnosis of cystadenoma. In 50% of cases, the diagnosis of cystadenoma was therefore acquired as a result of an incidental finding. The patients were all female, median age 45 years. The liver resection included six cases of left hepatectomy, three left lobectomies, and three of the right hepatectomy. The operations were performed by laparotomy, with the exception of two left lobectomies completed laparoscopically. In all cases, the postoperative course was without major complications. The resection was radical in all cases and the median hospital stay was 5 days. At a median follow-up of 16 months (range 7-30), all patients are alive and disease free. Biliary cystadenomas can easily be misunderstood and interpreted as simple hepatic cysts. Radical surgical resection is necessary and provides good short- and long-term outcomes.

    2012-01-01

    Full Text Available Primary biliary cirrhosis (PBC is a cholestatic liver disease of autoimmune origin, characterised by the destruction of small intrahepatic bile ducts. The disease has an unpredictable clinical course but may progress to fibrosis and cirrhosis. The diagnostic hallmark of PBC is the presence of disease-specific antimitochondrial antibodies (AMA, which are pathognomonic for the development of PBC. The disease overwhelmingly affects females, with some cases of male PBC being reported. The reasons underlying the low incidence of males with PBC are largely unknown. Epidemiological studies estimate that approximately 7–11% of PBC patients are males. There does not appear to be any histological, serological, or biochemical differences between male and female PBC, although the symptomatology may differ, with males being at higher risk of life-threatening complications such as gastrointestinal bleeding and hepatoma. Studies on X chromosome and sex hormones are of interest when studying the low preponderance of PBC in males; however, these studies are far from conclusive. This paper will critically analyze the literature surrounding PBC in males.

    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.

    Ceftriaxone is known to induce reversible precipitations, known as pseudolithiasis, in the gallbladder and urinary tract. The aim of this study was to investigate the incidence and predisposing factors that contribute to this side effect. A prospective study was conducted in 156 children admitted for the treatment of various infections with different daily ceftriaxone doses (50 mg/kg, 75 mg/kg, and 100 mg/kg). Sonographic examinations of the gallbladder and urinary tract were performed before treatment on the third and seventh day of therapy, and at the first and second month after the end of treatment. Patients with positive findings were followed with weekly sonographic examinations until the abnormality resolved. Abnormal gallbladder sonograms were demonstrated in 27 children (17%); 16 of them (10%) had gallbladder lithiasis, 11 had gallbladder sludge (7%) (n = 4 on the third day, n = 23 on the seventh day), and 1 developed urolithiasis (0.6%). Five children (19%) were symptomatic. The abnormalities resolved after a mean of 16 days (range 10-30 days). Patients with pseudolithiasis were older and treated with higher drug doses than those with normal sonographic findings (P Biliary pseudolithiasis (and infrequently nephrolithiasis) usually occurs in children receiving high doses of ceftriaxone. It is generally asymptomatic. When this reversible complication becomes symptomatic, unnecessary cholecystectomy should be avoided.

    Full Text Available Introduction: Isolated obstruction of the ureteropelvic junction and the vesico-ureteric junction are the two most common causes of hydronephrosis in a pediatric population. [1] They do not pose diagnostic difficulties when are present alone but when together can be difficult to diagnose. Here, we discuss the problems we faced when we encountered these two anomalies in the same ureter and the way in which we managed them. Aim: To assess the difficulties in diagnosis of pediatric patients who present with both ureteropelvic junction obstruction (UPJO and vesico-ureteric junction obstruction (VUJO in the ipsilateral ureter and their management protocol. Materials and Methods: This is a retrospective study. The study period is from 1 January 2004 to 31 December 2011. Out of 254 children who were diagnosed to have hydronephrosis due to UPJO in our institute, 5 patients (in the age range of 5 to 10 years had both UPJO and VUJO in the ipsilateral ureter. The problems we faced in diagnosing the two conditions are mentioned with a literature review. Results: Operative intervention was used in four out of five patients; none of the patients had an accurate diagnosis before surgery. All patients were suspected of having double obstruction during pyeloplasty when appropriate size double J stent could not be negotiated through the vesicoureteric junction into the bladder. Postoperative nephrostogram confirmed the diagnosis in all patients. Conclusion: Children with double obstruction of the ipsilateral ureter present as a diagnostic dilemma. Because of the rarity of this condition it can escape the eye of even an astute clinician. Early diagnosis can be made if this condition is kept in mind while treating any hydronephrosis due to UPJO or UVJO.

  10. Biliary Surgery Via Minilaparotomy — A Limited Procedure for Biliary Lithiasis

    Full Text Available Cholelithiasis until now has been treated using solvents, lithotripsy via a biliary endoscope, laser or shock wave lithotripsy, and laparoscopic cholecystectomy. have developed a new surgical treatment for cholelithiasis in which a cholecystectomy is performed through a minilaparotomy. This paper presents this new technique and discusses the principles of surgery for cholelithiasis using this technique. This procedure is performed by a 2 to 3 cm subcostal skin incision in the right hypochondrium. More than 400 patients were treated by this technique. This procedure is not different in terms of blood loss .or operation time from conventional methods, and no significant complications have occurred. Intraoperative X-ray examination is performed routinely because of easy insertion of a tube from the cystic duct into the bile duct. Reduction of the length of the incision greatly facilitates postoperative recovery, shortening the hospital length-of-stay to within 3 days. The surgical manipulation of only a limited area of the upper abdomen is unlikely to induce postoperative syndromes, such as adhesions or ileus. Following this experience, a biliary drainage procedure based on cholangionmanomery and primary closure of the choledochotomy was introduced. This approach allowed even patients with choledocholithiasis to undergo a minilaparotomy and be discharged within one week.

    In patients with obstructive jaundice caused by malignant stricture of the extrahepatic bile duct we compared survival time, complication rates, hospitalisation requirements, and quality of life after palliation by endoscopic endoprosthesis or bypass surgery. During diagnostic endoscopic cholangiography 50 patients were randomised to the two treatment alternatives. All 25 patients randomised to endoprosthesis were treated by this procedure, whereas only 19 of 25 patients randomised to bypass surgery underwent operative biliary-digestive anastomosis. Life table analysis revealed no difference in survival between treatment groups or randomisation groups. No differences were found when other variables were compared. We conclude, that palliation of obstructive jaundice in malignant bile duct obstruction with endoscopically introduced endoprosthesis is as effective as operative bypass. PMID:2475392

    Aims To develop a clinical cardiac risk algorithm for stable patients with suspected CAD based upon angina typicality and CAD risk factors. Methods and Results Between 2004 and 2011, 14,004 adults with suspected CAD referred for cardiac imaging were followed: 1) 9,093 patients for CCTA (CCTA-1) followed for 2.0 years; 2) 2,132 patients for CCTA (CCTA-2) followed for 1·6 years, and 3) 2,779 patients for exercise myocardial perfusion scintigraphy followed for 5.0 years. A best-fit model from CCTA-1 for prediction of death or myocardial infarction (MI) was developed, with integer values proportional to regression coefficients. Discrimination was assessed using C-statistic. The validated model was also tested for estimation of the likelihood of obstructive CAD, defined as ≥50% stenosis, as compared to method of Diamond and Forrester (D-F). Primary outcomes included all-cause mortality and non-fatal MI. Secondary outcomes included prevalence of angiographically obstructive CAD. In CCTA-1, best-fit model discriminated individuals at risk of death or MI (C-statistic 0·76). The integer model ranged from 3-13, and corresponded to 3-year death risk or MI of 0·25% to 53·8%. When applied to the CCTA-2 and MPS, the model demonstrated C-statistics of 0·71 and 0·77. Both best-fit (C=0·76, 95% CI 0·746-0·771) and integer model (C=0·71, 95% CI 0·693-0·719) performed better than D-F (C=0·64; 95% CI, 0·628-0·659) for estimating obstructive CAD. Conclusions For stable symptomatic patients with suspected CAD, we developed a history-based method for prediction of death and obstructive CAD. PMID:25865923

  13. Linking human beta retrovirus infection with primary biliary cirrhosis.

    2010-01-01

    Several environmental agents have been linked with primary biliary cirrhosis (PBC) that include bacteria, xenobiotics and viruses. A human beta retrovirus (HBRV) related to mouse mammary tumor virus has been cloned and characterized from patients with PBC. This agent can be detected in the majority of patients' perihepatic lymph nodes by immunochemistry and RT-PCR. The HBRV has recently been isolated in culture and integration sites have been identified in the genome of patients to provide convincing evidence of beta retrovirus infection in patients. Three lines of evidence support a role for the virus in PBC. First, the beta retrovirus is linked with aberrant expression of mitochondrial protein(s) on the biliary epithelium cell (BEC) surface, a disease specific phenotype. Second, the related agent, mouse mammary tumor virus has been linked with autoimmune biliary disease in the NOD.c3c4 mouse model for PBC. In this mouse model, the virus is localized to diseased biliary epithelium that also display aberrant expression of the mitochondrial autoantigens. In translational studies, both patients with PBC and NOD.c3c4 mice demonstrate significant improvement in biliary disease with combination antiviral therapy. An overview of the biological relevance of the beta retrovirus infection in PBC will be discussed in this review. Copyright 2010 Elsevier Masson SAS. All rights reserved.

    Endoscopic ultrasound (EUS) and Magnetic Endoscopic Cholangiopancreatography (MRCP) are important supplementary methods used for endoscopic extraction of common bile duct stones. The technical characteristics of both methods are excellent. If EUS is used for diagnostic purposes in diagnostic of biliary tree disorders there are almost no adverse consequences compared with other indication for this method. Nevertheless, the results are related to experience of physician. Advance of EUS compared to MRCP is its sensitivity and specificity even in cases where stones are small and dilation of biliary tract is minor. The role of EUS and ERCP in reveal of biliary tree stones and disorders is clearly defined. Comparasion of these two methods should be prospective and used in cases where definitive diagnosis is unclear. If EUS reveal stones in biliary tree then ERCP should be done in same session. Beside its role in excluding biliary pancreatitis, EUS can be used for examination of patient with acute and recurrent pancreatitis and is excellent for revealing ductal and parenchymal abnormalities of pancreas.

    Partial spontaneous rupture of the upper urinary tract is rare and usually associated with nephrolithiasis. Other reported causes, apart from instrumentation and trauma, involve obstructive ureteral tumor in the pelvic cavity, retroperitoneal fibrosis, fluid overload, and pregnancy. We report a case of spontaneous rupture of renal pelvis secondary to ureteral obstruction caused by urothelial tumor, clinically suspected and evaluated by CT scans and MRIs, discussing the relevant findings for diagnosis.(author)

    To compare the outcome of patients affected by biliary leak after major biliary surgery and treated with percutaneous transhepatic biliary drainage (PTBD) alone with that of similar patients treated with PTBD and concurrent positioning of an occlusion balloon (PTBD-OB). We retrospectively reviewed the results of the use of PTBD or PTBD-OB performed at our institution from 2004 to 2008 in patients with post-surgical biliary leak. Sixteen patients entered the evaluation. PTDB alone was performed in 9 men (age 59.7 {+-} 13.4 years [mean {+-} standard deviation]; median 60 years), while PTBD-OB was performed in 7 patients (5 men, 2 women, age 71.3 {+-} 9.3 years; median 68 years). No significant difference between groups was found regarding age (p = 0.064) and sex (p = 0.175) distribution, number of procedures (3.1 {+-} 1.62; 2 vs 1.7 {+-} 1.1; 1, p = 0.151), and days of disease before recovery, death or modification of treatment (51.6 {+-} 66.8; 23 vs 18.6 {+-} 15.1; 14, p = 0.266). The number of patients treated with PTBD-OB who fully recovered (7/7, 100%) was significantly higher than that of patients treated with PTBD alone (4/9, 44%, p = 0.034). This procedure appears to be clinically effective, being associated with a higher probability of recovery in patients treated for post-surgical biliary leak. Further studies are needed to confirm these preliminary results. (orig.)

    2013-10-01

    The aim of this study was to evaluate the possible protective effects of Urtica dioica (UD) against liver damage in the common bile duct-ligated rats. A total of 24 male Sprague Dawley rats were divided into three groups, namely, control, bile duct ligation (BDL) and BDL + received UD groups, containing eight animals in each group. The rats in UD-treated groups were given UD oils (2 ml/kg) once a day intraperitoneally for 2 weeks starting 3 days prior to BDL operation. The change demonstrating the bile duct proliferation and fibrosis in expanded portal tracts includes the extension of proliferated bile ducts into the lobules; inflammatory cell infiltration into the widened portal areas were observed in BDL group. Treatment of BDL with UD attenuated alterations in liver histology. The α-smooth muscle actin, cytokeratin-positive ductular proliferation and the activity of terminal deoxynucleotidyl transferase dUTP nick end labeling in the BDL were observed to be reduced with the UD treatment. The data indicate that UD attenuates BDL-induced cholestatic liver injury, bile duct proliferation and fibrosis.

    Cholestatic patients often present with clinical features suggestive of adrenal insufficiency. In the bile duct-ligated (BDL) model of cholestasis, the hypothalamic-pituitary-adrenal (HPA) axis is suppressed. The consequences of this suppression on cholangiocyte proliferation are unknown. We evaluated 1) HPA axis activity in various rat models of cholestasis and 2) effects of HPA axis modulation on cholangiocyte proliferation. Expression of regulatory molecules of the HPA axis was determined after BDL, partial BDL, and α-naphthylisothiocyanate (ANIT) intoxication. The HPA axis was suppressed by inhibition of hypothalamic corticotropin-releasing hormone (CRH) expression by central administration of CRH-specific Vivo-morpholinos or by adrenalectomy. After BDL, the HPA axis was reactivated by 1) central administration of CRH, 2) systemic ACTH treatment, or 3) treatment with cortisol or corticosterone for 7 days postsurgery. There was decreased expression of 1) hypothalamic CRH, 2) pituitary ACTH, and 3) key glucocorticoid synthesis enzymes in the adrenal glands. Serum corticosterone and cortisol remained low after BDL (but not partial BDL) compared with sham surgery and after 2 wk of ANIT feeding. Experimental suppression of the HPA axis increased cholangiocyte proliferation, shown by increased cytokeratin-19- and proliferating cell nuclear antigen-positive cholangiocytes. Conversely, restoration of HPA axis activity inhibited BDL-induced cholangiocyte proliferation. Suppression of the HPA axis is an early event following BDL and induces cholangiocyte proliferation. Knowledge of the role of the HPA axis during cholestasis may lead to development of innovative treatment paradigms for chronic liver disease. PMID:21979757

    Biliary cystadenoma and cystadenocarcinoma are rare neoplasms of the biliary ductal system. The authors present 2 cases of biliary cystadenoma and 3 cases of cystadenocarcinoma. The typical sonographic appearance of these tumors is a large intrahepatic globular or ovoid thick walled cystic mass which often contains multiple septations with papillary growth and solid portion. Low-level internal echoes may be seen within the cystic mass. The characteristic CT findings of these tumors are multiloculated cystic mass, thick septations with papillary projections and solid portion within the cystic mass. Angiographical characteristics of these tumors are hypovascular mass with frequent abnormal clusters of tumor vessels within the walls on arterial phase and accumulation of contrast material along the wall or internal septation on delayed film.

    Full Text Available Primary biliary cirrhosis (PBC is a slowly progressive cholestatic liver disease of autoimmune etiology. The initial presentation of PBC is varies from asymptomatic, abnormal liver biochemical tests to overt cirrhosis. Unlike other autoimmune liver diseases, PBC has rarely been reported in childhood. We report a case of primary biliary cirrhosis in a 12-year-old girl. In addition to characteristic histology features, strongly positive antimitochondrial antibodies, increased liver enzyme levels, increased serum quantitative immunoglobulin M levels, and cholestasis were discovered. She had been treated with ursodeoxycholic acid. In the world literature, we found only few pediatric patients of primary biliary cirrhosis. Aetiology, pathogenesis, the long-term natural history, and prognosis remain obscure. Due to increased awareness of early-onset PBC, rather than typical older ones, further pediatric cases may be discovered.

    Full Text Available Background. Acute biliary diseases during pregnancy have been classically managed conservatively. Advances in minimally invasive surgery and the high recurrence rate of symptoms observed changed this management. Methods. This is a prospective observational study. Initial management was medical. Unresponsive patients were treated with minimally invasive techniques including gallbladder percutaneous aspiration or cholecystostomy, endoscopic retrograde cholangiography, and laparoscopic cholecystectomy, depending on the pregnancy trimester and underlying diagnosis. Results. 122 patients were admitted. 69 (56.5% were unresponsive to medical treatment. Recurrent gallbladder colic was the most frequent indication for minimally invasive intervention, followed by acute cholecystitis, choledocholithiasis, and acute biliary pancreatitis. 8 patients were treated during the first trimester, 54 during the second, and 7 during the last trimester. There was no fetal morbidity or mortality. Maternal morbidity was minor with no mortality. Conclusion. Acute biliary tract diseases during pregnancy may be safely treated with minimally invasive procedures according to the underlying diagnosis and to the trimester of pregnancy.

    Real time gray scale ultrasonography of upper abdomen was carried out in 1237 cases for varied indications. Overall prevalence of biliary lithiasis was 11.56% with female to male ratio of 4:1. Fifty years and below, female to male ratio was 6.5:1. 88.8% cases of biliary lithiasis were 60 years and below. Gall bladder dyspepsia (61.5%) and right upper quadrant pain (41%) were the main presenting features of biliary lithiasis. 26 patients (18%) presented with acute abdomen. Asymptomatic gallstones were found in 25 (17.5%) cases. Solitary calculus was less common than multiple calculi with a ratio of 1:4. Amongst cases of multiple calculi the small sized (2-4 mm) variety was the maximum (49%) followed by medium sized (5-10mm) and large sized (>10mm) calculi respectively.

    Up to 40% of ceftriaxone is excreted unchanged into the bile and, due to its high calcium-binding affinity, it may form a salt that can provoke biliary lithiasis. Echography revealed that biliary lithiasis was present in 12-45% of patients treated with ceftriaxone as early as the second day of treatment. Lithiasis is usually asymptomatic and disappears in less than 2 months. Symptomatic cases and patients requiring cholecystectomy have been described in the literature. We present four children, evaluated in 1999, who presented asymptomatic cholelithiasis between the second and fourth day of ceftriaxone treatment. Biliary lithiasis was found after 2-4 days of treatment, with resolution of the lithiasis between 1-4 months after the end of therapy.

    M3 muscarinic acetylcholine receptor (M3R) is expressed in biliary tracts as well as in exocrine glands. It is reported that some patients with primary biliary cirrhosis (PBC) carry autoantibodies against M3R. The aim of this study is to clarify the presence, potential use as diagnostic marker and clinical roles of anti-M3R antibodies in PBC. We synthesized peptides encoding the extracellular domains of human-M3R, including the N-terminal region, the first, second and third extracellular loops. Antibodies against these regions were examined by peptide-based enzyme-linked immunoassay in sera of 90 patients with PBC and 40 with chronic hepatitis C (CHC), 21 with non-alcoholic steatohepatitis (NASH), 10 with primary sclerosing cholangitis (PSC), 14 with obstructive jaundice, 10 with drug-induced liver injury and 42 healthy controls. Antibodies to the N-terminal, first, second and third loop were detected in 90.0% (81/90), 73.3% (66/90), 76.7% (69/90) and 66.7% (60/90) of PBC, in 67.5% (27/40), 10.0% (4/40), 67.5% (27/40) and 27.5% (11/40) of CHC, in 85.7% (18/21), 9.5% (2/21), 4.8% (1/21) and 57.1% (12/21) of NASH, in 60.0% (6/10), 20.0% (2/10), 60.0% (6/10) and 60.0% (6/10) of PSC, in 100.0% (14/14), 0% (0/14), 64.3% (9/14) and 78.6% (11/14) of obstructive jaundice, in 100.0% (10/10), 0% (0/10), 30.0% (3/10) and 10.0% (1/10) of drug-induced liver injury, and in 4.8% (2/42), 7.1% (3/42), 2.4% (1/42) and 2.4% (1/42) of the controls, respectively. A high frequency of PBC carried anti-M3R antibodies. Anti-M3R antibodies against the first loop of M3R are a potentially useful diagnostic marker for PBC. © 2014 The Japan Society of Hepatology.

  9. Use of Methyl Tert-Butyl Ether for the Treatment of Refractory Intrahepatic Biliary Strictures and Bile Casts: A Modern Perspective

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Cholelithiasis is a prevalent problem in the United States with 14% or more adults affected. Definitive treatment of cholelithiasis is cholecystectomy. When cholecystectomy yields minimal resolution treatment options include expectant management of asymptomatic gallstones or endoscopic retrograde cholangiopancreatogram. We present a case of intrahepatic biliary casts where surgical option was not possible, interventional radiology was unsuccessful, and methyl tert-butyl ether was used to dissolve the biliary obstruction. Dissolution therapy of gallstones was first reported in 1722 when Vollisnieri used turpentine in vitro. While diethyl ether has excellent solubilizing capacity, its low boiling point limited its use surgically as it vaporizes immediately. Diethyl ether can expand 120-fold during warming to body temperature after injection into the biliary system making it impractical for routine use. The use of dissolution is out of favor due to the success of laparoscopic cholecystectomy. Epidemiological studies have shown the general population should have minimal concerns from passive exposure. Dissolution using MTBE remains a viable option if surgical or endoscopic options are not available. However, because of risks involved to both the patient and the staff, careful multidisciplinary team approach must be undertaken to minimize the risks and provide the best possible care to the patient.

    In extrahepatic biliary atresia (EHBA) obstruction of the biliary tree causes severe cholestasis leading to cirrhosis and death if left untreated in a timely manner. Infants with cholestasis may undergo many tests before EHBA diagnosis is reached. The role and place of preoperative liver biopsy in the diagnostic paradigm for EHBA have not been established. We conducted a systematic review of MEDLINE, Embase, and CENTRAL to obtain all publications describing the sensitivity/specificity/accuracy/positive predictive value (PPV)/negative predictive value (NPV) of preoperative liver biopsy in infants with cholestasis. Screening, data extraction, and quality assessment were done in duplicate. Extracted data are described narratively and analyzed using forest plots and receiver operating characteristic curves. A total of 22 articles were included. Overall, the pooled accuracy of preoperative liver biopsy was 91.7%, with a sensitivity of 91.2%, specificity of 93.0% (n=1231), PPV of 91.2%, NPV of 92.5% (n=1182), and accuracy of 91.6% (n=1106). In patients who were 60days or less at time of presentation or diagnosis, the pooled sensitivity, specificity, PPV, NPV, and accuracy were 96.4%, 96.3%, 95.8%, 96.3%, and 94.9%, respectively. Quantitative analysis demonstrated preoperative biopsy to be both highly specific and sensitive in diagnosing EHBA preoperatively. It is a highly reliable test that offers a means of arriving at an early definitive diagnosis of EHBA. Copyright © 2016 Elsevier Inc. All rights reserved.

    To compare the feasibility and safety of US-guided right and left percutaneous transhepatic biliary drainage (PTBD). Between March 1998 and May 1999, 32 patients underwent 36 US-guided right or left PTBD in referred order, alternatively. The causes of biliary obstruction were bile duct stone (n=2), bile duct carcinoma (n=10), carcinoma of the pancreas (n=9), GB carcinoma (n=7), metastasis to the porta hepatis (n=3), and carcinoma of the ampulla of vater (n=1). Technical success, procedure time, fluoroscopic time, and complications were evaluated. PTBD was successful in 94% of both right and left approach. The average procedure time was 9.7 {+-}3.8 min. in the right approach and 9.6 {+-}3.1 min. in the left approach, respectively (p=0.794). The average fluoroscopic time were 3.9{+-}2.4 min. in the right approach and 3.8{+-}2.2 min. in the left approach (p=0.892). A major complication, bile peritonitis, occurred in one of 16 patient with right-sided approach. Minor complications occurred in six right (2 hemobilia, 3 tube malfunction, 1 cholangitis) and three left (1 hemobilia, 1 fever, 1cholangitis) PTBD. There were no significant difference in the complication rates between right and left PTBD (p=0.729). There were no significant differences in feasibility and safety in US-guided right and left PTBD.

    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.

    Metaplasias often have characteristics of developmentally related tissues. Pancreatic metaplastic ducts are usually associated with pancreatitis and pancreatic ductal adenocarcinoma. The tuft cell is a chemosensory cell that responds to signals in the extracellular environment via effector molecules. Commonly found in the biliary tract, tuft cells are absent from normal murine pancreas. Using the aberrant appearance of tuft cells as an indicator, we tested if pancreatic metaplasia represents transdifferentiation to a biliary phenotype and what effect this has on pancreatic tumorigenesis. We analyzed pancreatic tissue and tumors that developed in mice that express an activated form of Kras (Kras(LSL-G12D/+);Ptf1a(Cre/+) mice). Normal bile duct, pancreatic duct, and tumor-associated metaplasias from the mice were analyzed for tuft cell and biliary progenitor markers, including SOX17, a transcription factor that regulates biliary development. We also analyzed pancreatic tissues from mice expressing transgenic SOX17 alone (ROSA(tTa/+);Ptf1(CreERTM/+);tetO-SOX17) or along with activated Kras (ROSAtT(a/+);Ptf1a(CreERTM/+);tetO-SOX17;Kras(LSL-G12D;+)). Tuft cells were frequently found in areas of pancreatic metaplasia, decreased throughout tumor progression, and absent from invasive tumors. Analysis of the pancreatobiliary ductal systems of mice revealed tuft cells in the biliary tract but not the normal pancreatic duct. Analysis for biliary markers revealed expression of SOX17 in pancreatic metaplasia and tumors. Pancreas-specific overexpression of SOX17 led to ductal metaplasia along with inflammation and collagen deposition. Mice that overexpressed SOX17 along with Kras(G12D) had a greater degree of transformed tissue compared with mice expressing only Kras(G12D). Immunofluorescence analysis of human pancreatic tissue arrays revealed the presence of tuft cells in metaplasia and early-stage tumors, along with SOX17 expression, consistent with a biliary phenotype

    We report here on a case of extrahepatic biliary cystadenoma arising from the common hepatic duct. A 42-year-old woman was evaluated by us to find the cause of her jaundice. Ultrasonography and CT showed a cystic dilatation of the common hepatic duct and also marked dilatation of the intrahepatic duct. Direct cholangiography demonstrated a large filling defect between the left hepatic duct and the common hepatic duct; dilatation of the intrahepatic duct was also demonstrated. Following excision of the cystic mass, it was pathologically confirmed as a unilocular biliary mucinous cystadenoma arising from the common hepatic duct.

    A 14-year-old Maltese dog presented for complete medical examination due to intermittent vomiting and diarrhea observed during the previous two days. A single, solitary, lobulated cystic mass was observed in the liver upon ultrasonographic and computed tomographic examination. After surgical hepatic resection to remove the mass, histological examination revealed a multilocular cyst lined by cuboidal to columnar epithelial cells, which is consistent with biliary cystadenoma. Here, we report the clinical, clinicopathological, histopathological, and diagnostic imaging findings of biliary cystadenoma in a dog.

    Full Text Available A female newborn was admitted to our department 15 days after birth for insufficient sucking and jaundice. The patient’s blood and urine cultures were both positive for group B streptococcal (GBS infection. A maternal vaginal sample at 35 weeks’ gestation was negative for GBS in culture-based microbiologic screening. The patient recovered shortly after receiving systemic antibiotic therapy. On the basis of clinical evidence of white stool and progressive jaundice, we suspected that the newborn had complications related to congenital biliary atresia (CBA; surgery was performed. Isolates from the mother’s vaginal sample obtained when the patient was 25 days old, along with neonatal blood, revealed identical patterns (serotype VIII and sequence type 1 of GBS capsular and multilocus sequence typing, suggestive of maternal transmission. Molecular epidemiologic examination may be useful to clarify the transmission route and etiology; culture-based microbiologic screening appears to have limitations for detecting the route of transmission.

    to obtain survival rate and mortality-related factors of malignant obstructive jaundice patients. all medical records of obstructive jaundice inpatient at Cipto Mangunkusumo Hospital, Jakarta from January 2010 to December 2013 were reviewed retrospectively. The following factors were analyzed in terms of mortality: age, gender, sepsis, hypoalbumin, serum bilirubin level, serum CA 19-9 level, billiary drainage, non-ampulla Vateri carcinoma, and comorbid factors. total 181 out of 402 patients were enrolled in this study with male proportion was 58.6%, and patients aged 50 years or above was 57.5%. Multivariate analysis showed that only sepsis, unsuccessful or no prior biliary drainage and Charlson comorbid score ≥4 were independent predictors of mortality. Patients with significant prognostic factors had median survival 14 days compared with overall median survival 26 days. Score ≥2 identified as the highest prognostic score threshold with sensitivity 68%, specificity 75%, and AUC on ROC curve 0.769. sepsis, unsuccessful or no prior bilirary drainage, and Charlson comorbid score ≥4 are factors significantly associated with shortened survival in malignant obstructive jaundice patients. Prognostic score  ≥2 was determined to classify patients into high risk mortality group. Mortality of patients with those significant prognostic factors can be predicted in 76.9%.

    Full Text Available Obstructive nephropathy is the functional and /or parenchymal renal damage secondary to the urinary tract occlusion at any part of it. The inducing urinary obstruction diseases can vary depending on the patient´s age and gender. There are many renal dysfunction inducing mechanisms involved in this entity: increase in the intra-luminal pressure, ureteral dilatation with ineffective ureteral peristalsis, glomerular ultrafiltration net pressure reduction, intra-renal glomerular blood flux reduction due to vasoconstriction, and local disease of chemotactic substances. Obstructive nephropathy can also lead to hypertension (vasoconstriction-hypervolemia, hyperkalemia, metabolic acidosis (aldosterone resistance, diabetes insipidus (vasopressine resistance. In conclusion, since obstructive nephropathy is a potentially reversible cause of renal dysfunction, it should always be taken into account among the differential diagnosis of renal failure inducing mechanisms.

    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.

    Purpose: To investigate the ability of contrast-enhanced ultrasound (CEUS) to differentiate benign from malignant lesions causing biliary duct obstruction. Materials and Methods: Between November 2006 and December 2013, 59 patients with bile duct obstruction of undetermined cause in baseline ultrasound underwent CEUS study. The enhancement and posterior washout were analyzed in real time all along the study duration (5′). The final diagnosis suggested by CEUS was compared with histologic diagnosis (47.5%) or with radiologic follow-up with TC, RM or ERCP. Results: Final diagnoses included 42 malignant lesions (cholangiocarcinoma n=22, metastases n=6, pancreatic carcinoma n=6, hepatocarcinoma n=4, gallbladder carcinoma n=2, ampullary carcinoma n=1 and lymphoma n=1) and 17 benign lesions (lithiasis or biliary sludge n=15, xanthogranulomatous cholecystitis n=1 and indeterminate n=1). CEUS accuracy compared with final diagnoses based on combined reference standard was 86.4%. CEUS correctly identified 36 of 42 malignant lesions (sensibility 85.7%) and 15 of 17 benign lesions (specificity 88.2%). The positive predictive value of CEUS for malignancy was 94.7%, while the negative predictive value was 71.4%. Conclusion: CEUS is useful to differentiate between benign and malignant causes of obstructive jaundice. This technique improves the detection of bile duct invasion in hepatic neoplasms and permits better evaluation of intra- and extraductal extension of hilar hepatobiliary tumors. PMID:27689143

    To evaluate the outcomes of patients undergoing percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy. Fifty patients (mean age, 62.4 years; range, 27-86 years) who underwent percutaneous placements of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy were included. The technical success rate, clinical success rate, complication rate, stent patency, patient survival and factors associated with stent patency were being evaluated. The median interval between the gastrectomy and stent placement was 23.1 months (range, 3.9-94.6 months). The 50 patients received a total of 65 stents without any major procedure-related complications. Technical success was achieved in all patients. The mean total serum bilirubin level, which had been 7.19 mg/dL ± 6.8 before stent insertion, decreased to 4.58 mg/dL ± 5.4 during the first week of follow-up (p < 0.001). Clinical success was achieved in 42 patients (84%). Percutaneous transhepatic biliary drainage catheters were removed from 45 patients (90%). Infectious complications were noted in two patients (4%), and stent malfunction occurred in seven patients (14%). The median stent patency was 233 ± 99 days, and the median patient survival was 179 ± 83 days. Total serum bilirubin level after stenting was an independent factor for stent patency (p = 0.009). Percutaneous transhepatic placement of a biliary stent for obstructive jaundice secondary to metastatic gastric cancer after gastrectomy is a technically feasible and clinically effective palliative procedure.

    Full Text Available Plastic stents used for the treatment of biliary obstruction will become occluded over time due to microbial colonization and formation of biofilms. Treatment of stent-associated cholangitis is often not effective because of inappropriate use of antimicrobial agents or antimicrobial resistance. We aimed to assess the current bacterial and fungal etiology of stent-associated biofilms, with particular emphasis on antimicrobial resistance.Patients with biliary strictures requiring endoscopic stent placement were prospectively enrolled. After the retrieval of stents, biofilms were disrupted by sonication, microorganisms were cultured, and isolates were identified by matrix-associated laser desorption/ionization time-of-flight (MALDI-TOF mass spectrometry and/or biochemical typing. Finally, minimum inhibitory concentrations (MICs were determined for various antimicrobial agents. Selected stents were further analyzed by fluorescence in situ hybridization (FISH.Among 120 patients (62.5% males, median age 64 years with biliary strictures (35% malignant, 65% benign, 113 double pigtail polyurethane and 100 straight polyethylene stents were analyzed after a median indwelling time of 63 days (range, 1-1274 days. The stent occlusion rate was 11.5% and 13%, respectively, being associated with a significantly increased risk of cholangitis (38.5% vs. 9.1%, P<0.001. Ninety-five different bacterial and 13 fungal species were detected; polymicrobial colonization predominated (95.8% vs. 4.2%, P<0.001.

    The purpose of this study was to investigate the effect of probenecid, an inhibitor of the MRP2/ ABCC transporter, on the pharmacokinetics and transport of belotecan (7-[2-(N-isopropylamino)ethyl]-(20S)-camptothecin). The effect of probenecid on the pharmacokinetics of belotecan was studied in rats. When belotecan was injected as a bolus dose of 5 mg/kg after probenecid was infused at a rate of 42.8 mg/2 mL/h/kg, the cumulative biliary excretion amounts and biliary clearance (CL(b)) of belotecan decreased (28.29 +/- 2.83 versus 19.96 +/- 1.45% of dose and 161.01 +/- 26.95 versus 92.66 +/- 1.45 mL/min/kg), whereas the systemic pharmacokinetics did not change. This indicates that the MRP2 transporter is involved in the biliary excretion of belotecan. The involvement of MRP2 in the secretory transport was further characterized using Caco-2 cell monolayers expressing MRP2. The apparent permeability across Caco-2 cell monolayers from basolateral to apical was 2.3 times greater than that from the apical to the basolateral side at the 50 microM belotecan. In addition, probenecid significantly decreased the basolateral-to-apical transport of belotecan (52.9%). These results indicate that MRP2 is involved in the secretory transport of belotecan in biliary excretion.

    Intrahepatic biliary lithiasis is fairly rare in western countries. In the case described here, liver stones had developed as a late consequence of biliary derivative surgery, which is well known to lead to this complication. However, this case is unusual because people who have undergone radical surgery for cancer of the head of the pancreas seldom survive long enough for liver stones to develop. Treatment for this 65-year-old woman, previously submitted to duodeno-cephalopancreatectomy, involved percutaneous balloon bilioplasty, with several passages in order to open the anastomosis. We then positioned two inner-outer biliary drains, through which repeated lavages were done. Finally, the patient underwent laser lithotripsy of the intrahepatic calculi and the fragments were cleared using a Dormia basket. Repeated cholangiographic monitoring showed progressively fewer stones, until the intrahepatic biliary tree was finally completely clear 120 days after the initial diagnosis. At the last follow-up, the patient was healthy, with normal blood values, considering her overall condition.

    Acute pathologies of the biliary tract in geriatric patients were examined in this study taking into account the major causes, treatment used and results obtained. All patients aged over 65 who had been hospitalised during the past 17 years for acute pathologies of the biliary tract (564 cases, equivalent to 34.2% of all in-patients suffering from acute biliary pathologies) were included in the study. These patients were then subdivided into 3rd and 4th age groups (65-74 and lithiasic disease of the cholecystus (61.2%) and VBP (17.7%), whereas 45 patients, equivalent to 49.5%, presented tumours with jaundice. Out of a total of 179 cases in patients in the 4th age group, equivalent to 39.3%, 119 (66.5%) were suffering from lithiasic cholecystitis and 16 (8.9%) from calcolosis of the VBP with jaundice. Cancer of the pancreas head was diagnosed in 27 patients (58.7%), whereas 9 (19.6%) had obstruent cancer of the biliary tract. The Authors conclude that both the preoperative preparation, the choice of operation and postoperative treatment give satisfactory results with a very low early mortality (0.8% in non-tumour cases and 6.9% in tumour cases).

    To analyze phospholipid profiles in intrahepatic bile from patients with primary sclerosing cholangitis (PSC) and secondary sclerosing cholangitis (SSC). Intrahepatic bile specimens collected via endoscopic retrograde cholangiography from 41 patients were analyzed. Fourteen of these patients were diagnosed with PSC, 10 with SSC, 11 with choledocholithiasis or no identifiable biliary disease, and 6 with cholangiocellular carcinoma (CCC). Bile acid, cholesterol, protein, and bilirubin contents as well as pancreas lipase activity in bile were determined by biochemical methods. Phosphatidylcholine (PC) and lysophosphatidylcholine (LPC) species were quantified using nano-electrospray ionization tandem mass spectrometry. Bile from all the examined patient groups showed a remarkably similar PC and LPC species composition, with only minor statistical differences. Total biliary PC concentrations were highest in controls (8030 ± 1843 μmol/L) and lowest in patients with CCC (1969 ± 981 μmol/L) (P = 0.005, controls vs SSC and CCC, respectively, P < 0.05). LPC contents in bile were overall low (4.2% ± 1.8%). Biliary LPC/PC ratios and ratios of biliary PC to bilirubin, PC to cholesterol, PC to protein, and PC to bile acids showed no intergroup differences. PC and LPC profiles being similar in patients with or without sclerosing cholangitis, these phospholipids are likely not of major pathogenetic importance in this disease group.

    To understand the change of the main pathogenic microbes of biliary infection and their resistance rates to 12 antibiotics so as to instruct rational application of antibiotics clinically. All isolates were identified by analytic products incorporation (API) bioMerieux. The susceptibility of antibiotics to 470 pathogenic microbes was tested by minimal inhibition concentration (MIC). There were 470 pathogenic microbes with positive biliary culture. The percentage of Escherichia coli, intestinal cocci and Klebsiella pneumoniae was 129 (27.4%), 82 (17.4%) and 76 (16.2%), respectively. In the resistance rates of the gram negative bacilli to 12 antibiotics, the lowest was 4.0% for imipenem followed by. 14.1% Ceftazidime and 16.9% amikacin. In the resistant rates of the gram positive cocci to 12 antibiotics, and had the lowest rate was 6.0% for vancomycin and 16.4% for imipenem. The main pathogenic microbes of biliary infection were Escherichia coli, intestinal cocci and Klebsiella pneumoniae. Imipenem is the first used for biliary infection in dealing with multiresistant intestinal cocci.

    mainly on its etiopathogenesis, diagnosis, treatment and prognosis. SOURCES: MEDLINE and PubMed databases were searched using the following keywords: biliary atresia,etiopathogenesis, diagnosis, treatment, prognosis, children. SUMMARY OF THE FINDINGS: Extrahepatic biliary atresia is the main indication for liver transplantation among pediatric patients. As to its etiology, cytomegalovirus, reovirus and rotavirus have been widely investigated as possible triggers of the immunomediated obstruction of the biliary tree. The immune response, especially the predominant TH1 and interferon-gamma responses, genetic susceptibility and disorders related to the embryonic development of the biliary tree can play a role in the etiopathogenesis of extrahepatic biliary atresia. Yet today, portoenterostomy is the only available treatment, with better results when performed in the first 2 months of life. As to prognosis, all untreated children eventually die due to complications resulting from portal hypertension and liver cirrhosis, and most treated children have to undergo liver transplantation. CONCLUSIONS: Extrahepatic biliary atresia is still the major indication for pediatric liver transplantation, and to change this scenario some more light should be shed upon the etiopathogenesis of biliary atresia in different disease phenotypes. Future research into the role of interferon-gamma and of other cytokines is necessary in order to assess whether these aspects should be potential targets for therapeutic intervention.

    To study serum and bile cytokines dynamics in patients with non-tumoral obstructive jaundice and suppurative cholangitis. Comparative study of serum and bile cytokines in 49 operated patients with biliary pathology was performed. Patients were divided into 3 groups. The first group included 24 patients with acute calculous cholecystitis (ACCh), the second group consisted of 12 patients with chronic calculous cholecystitis (CCCh) and the third group included 13 patients with choledocholithiasis complicated by obstructive jaundice and suppurative cholangitis. All patients had increased level of TNF-α, IL-4 и IL-6. There was augmentation of biliary cytokines in patients with obstructive jaundice compared with those with acute and chronic calculous cholecystitis. In patients with obstructive jaundice and suppurative cholangitis the highest levels of cytokines were observed. Patients with obstructive jaundice (OJ), suppurative cholangitis (SCh) and chronic calculous cholecystitis had higher levels of cytokines in both blood and bile than in those with OJ, SCh and acute calculous cholecystitis that is explained by development of purulent inflammation on background of previous cytokines imbalance and chronic inflammation. In general, patients with acute calculous cholecystitis had higher levels of TNF-α and IL-6 in blood serum and IL-4 in bile. Patients with chronic calculous cholecystitis had higher concentration of TNF-α and IL-4 in bile and IL-6 - in blood serum. Both forms of cholecystitis and their complications are associated with increased cytokines in serum and bile. The level of augmentation depends on the type of inflammation and complications. Comparative study of cytokines can be the most informative criterion to monitor the postoperative period.

    Contrast-enhanced magnetic resonance imaging and magnetic resonance cholangiopancreatography (MRCP), due to their excellent soft tissue contrasts, have become first-line noninvasive tests in the characterization and detection of both hepatic and pancreaticobiliary pathologies. MRCP is also helpful in detecting the level and cause of obstruction in patients presenting with jaundice. Cholangiocarcinoma (CCA) is the most common primary malignant tumor arising from the bile duct epithelium, with extrahepatic tumors presenting more often than with intrahepatic ones. However, the diagnosis and management of CCA is made more complex by a variety of malignant and benign conditions that resemble CCA, including hepatocellular carcinoma variants such as the fibrolamellar variant of hepatocellular carcinoma, cholangiocellular carcinoma, biliary metastases, hepatic inflammatory pseudotumor, lymphoepithelioma-like carcinoma, confluent fibrosis, primary sclerosis cholangitis, and the secondary sclerosing cholangitis complex. Consequently, knowledge of the underlying risk factors and imaging characteristics of these conditions is important in differentiating between neoplastic and non-neoplastic conditions in order to reach a definite diagnosis. Endoscopic retrograde cholangiopancreatography should be reserved for those patients who require intervention or biopsy for histopathological diagnosis.

    Full Text Available AbstractBackground:Guidelines recommend that in suspected stable coronary artery disease (CAD, a clinical (non-invasive evaluation should be performed before coronary angiography.Objective:We assessed the efficacy of patient selection for coronary angiography in suspected stable CAD.Methods:We prospectively selected consecutive patients without known CAD, referred to a high-volume tertiary center. Demographic characteristics, risk factors, symptoms and non-invasive test results were correlated to the presence of obstructive CAD. We estimated the CAD probability based on available clinical data and the incremental diagnostic value of previous non-invasive tests.Results:A total of 830 patients were included; median age was 61 years, 49.3% were males, 81% had hypertension and 35.5% were diabetics. Non-invasive tests were performed in 64.8% of the patients. At coronary angiography, 23.8% of the patients had obstructive CAD. The independent predictors for obstructive CAD were: male gender (odds ratio [OR], 3.95; confidence interval [CI] 95%, 2.70 - 5.77, age (OR for 5 years increment, 1.15; CI 95%, 1.06 - 1.26, diabetes (OR, 2.01; CI 95%, 1.40 - 2.90, dyslipidemia (OR, 2.02; CI 95%, 1.32 - 3.07, typical angina (OR, 2.92; CI 95%, 1.77 - 4.83 and previous non-invasive test (OR 1.54; CI 95% 1.05 - 2.27.Conclusions:In this study, less than a quarter of the patients referred for coronary angiography with suspected CAD had the diagnosis confirmed. A better clinical and non-invasive assessment is necessary, to improve the efficacy of patient selection for coronary angiography.

  15. The phenomenology of specialization of criminal suspects.

    Directory of Open Access Journals (Sweden)

    Michele Tumminello

    Full Text Available A criminal career can be either general, with the criminal committing different types of crimes, or specialized, with the criminal committing a specific type of crime. A central problem in the study of crime specialization is to determine, from the perspective of the criminal, which crimes should be considered similar and which crimes should be considered distinct. We study a large set of Swedish suspects to empirically investigate generalist and specialist behavior in crime. We show that there is a large group of suspects who can be described as generalists. At the same time, we observe a non-trivial pattern of specialization across age and gender of suspects. Women are less prone to commit crimes of certain types, and, for instance, are more prone to specialize in crimes related to fraud. We also find evidence of temporal specialization of suspects. Older persons are more specialized than younger ones, and some crime types are preferentially committed by suspects of different ages.

    Bile acids stimulate intestinal epithelial proliferation in vitro. We sought to investigate the role of the bile acid receptor TGR5 in the protection of intestinal epithelial proliferation in obstructive jaundice. Intestinal tissues and serum samples were obtained from patients with malignant obstructive jaundice and from bile duct ligation (BDL) rats. Intestinal permeability and morphological changes in the intestinal mucosa were observed. The functions of TGR5 in cell proliferation in intestinal epithelial injury were determined by overexpression or knockdown studies in Caco-2 and FHs 74 Int cells pretreated with lipopolysaccharide (LPS). Internal biliary drainage was superior to external biliary drainage in recovering intestinal permeability and mucosal histology in patients with obstructive jaundice. In BDL rats, feeding of chenodeoxycholic acid (CDCA) decreased intestinal mucosa injury. The levels of PCNA, a marker of proliferation, increased in response to CDCA feeding and were paralleled by elevated TGR5 expression. CDCA upregulated TGR5 expression and promoted proliferation in Caco-2 and FHs 74 Int cells pretreated with LPS. Overexpression of TGR5 resulted in increased PCNA, cell viability, EdU incorporation, and the proportion of cells in S phase, whereas knockdown of TGR5 had the opposite effect. Our data indicate that bile acids promote intestinal epithelial cell proliferation and decrease mucosal injury by upregulating TGR5 expression in obstructive jaundice. Copyright © 2016 Elsevier Inc.

    To evaluate the feasibility and diagnostic accuracy of the balloon dilatation biopsy for the biliary stricture through the percutaneous transhepatic biliary drainage (PTBD) tract. The study included 35 patients who underwent balloon dilatation biopsy for the biliary stricture through the PTBD tract. Balloon dilatation was done with a balloon catheter of 10-mm or 12-mm diameter. Soft tissue adherent to the retrieved balloon catheter and soft tissue components separated by gauze filtration of evacuated bile were sampled for histopathologic examination. The results were compared with the final diagnosis which was made by clinical and imaging follow-up for mean 989 days (n = 34) and surgery with histopathologic examination (n = 1). Procedure-related complications and diagnostic accuracy were assessed. Tissues suitable for histopathologic examination were obtained in 31 out of 35 patients (88.6%). In 3 patients, self-limiting hemobilia was noted. No major complication was noted. The sensitivity, specificity, diagnostic accuracy, positive and negative predictive values for diagnosis of malignant stricture were 70.0%, 100%, 90.3%, 100%, and 87.5%, respectively. Balloon dilatation biopsy of the biliary stricture through the PTBD tract is a feasible and accurate diagnostic method. It can be a safe alternative to the endoscopic retrograde cholangiography biopsy or forceps biopsy through the PTBD tract.

  18. Primary Biliary Cirrhosis and Primary Sclerosing Cholangitis: an Update on MR Imaging Findings with Recent Developments.

    Kovač, Jelena Djokić; Weber, Marc-André

    2016-12-01

    Primary sclerosing cholangitis (PSC) and primary biliary cirrhosis (PBC) are the most common immune-mediated chronic cholestatic liver diseases leading to cirrhosis and liver failure. Although magnetic resonance imaging (MRI) is not a necessary procedure for the diagnosis of PBC, MRI is recommended for monitoring disease progression and early detection of complications. Even though liver cirrhosis subtypes have similar MR imaging features, there are some findings which could indicate PBC, such as the periportal halo sign. Additionally, MRI using diffusion-weighted imaging with apparent diffusion coefficient measurements provides non-invasive assessment of the stage of liver fibrosis. The role of cholangiography is crucial for the diagnosis of PSC. Since endoscopic retrograde cholangiography is an invasive procedure with occasional post-procedural complications, the latest guidelines suggest magnetic resonance cholangiography as a reference procedure for evaluation of patients suspected with PSC. Characteristic magnetic resonance cholangiography findings include multiple segmental strictures with slightly dilated ducts among them, usually on both intrahepatic and extrahepatic bile ducts. Furthermore, magnetic resonance cholangiography is useful in the follow-up of these patients, allowing for timely diagnosis of complications such as cholangiocellular carcinoma. With the exception of ursodeoxycholic acid, which slows the progression of PBC, the only curative treatment for both PSC and PBC is still liver transplantation. However, recurrent disease occurs in some patients indicating the need for development of new more effective therapies.

  19. Enzyme inhibition assay for pyruvate dehydrogenase complex: Clinical utility for the diagnosis of primary biliary cirrhosis

    2005-01-01

    Primary biliary cirrhosis (PBC) is usually diagnosed by the presence of characteristic histopathological features of the liver and/or antimitochondrial antibodies (AMA) in the serum traditionally detected by immunofluorescence. Recently, new and more accurate serological assays for the detection of AMA, such as enzyme-linked immunosorbent assay (ELISA), immunoblotting, and enzyme inhibition assay, have been developed. Of these, the enzyme inhibition assay for the detection of anti- pyruvate dehydrogenase complex (PDC) antibodies offers certain advantages such as objectivity, rapidity, simplicity, and low cost. Since this assay has almost 100% specificity, it may have particular applicability in screening the at-risk segment of the population in developing countries. Moreover, this assay could be also used for monitoring the disease course in PBC. Almost all sera of PBC-suspected patients can be confirmed for PBC or non-PBC by the combination results of immunoblotting and enzyme inhibition assay without histopathological examination. For the development of a “complete” or "gold standard" diagnostic assay for PBC, similar assays of the enzyme inhibition for anti-2-oxoglutarate dehydrogenase complex (OGDC) and anti-branched chain oxo-acid dehydrogenase complex (BCOADC) antibodies will be needed in future.

    Purpose: To evaluate the association between gadoxetic-acid-enhanced magnetic resonance (MR) imaging measurements and laboratory and clinical biomarkers of liver function and fibrosis. Materials and methods: One hundred thirty nine consecutive patients with suspected liver disease or liver tumor underwent gadoxetic-acid-enhanced MR imaging. MR imaging measurements during the hepatobiliary phase included biliary tract structure-to-muscle signal intensity ratio (SIR). These measurements were compared with Child-Pugh classification, end-stage liver disease (MELD) score, and aspartate aminotransferase-to-platelet ratio index (APRI). Results: The SIRs of cystic duct and common bile duct were significantly correlated with Child-Pugh classification (P = 0.012 for cystic duct and P < 0.0001 for common bile duct), MELD score (P = 0.0016 and P = 0.0033), and APRI (P = 0.0022 and P = 0.0015). The sensitivity, specificity, and area under the receiver-operating-characteristic curve were: (74%, 88%, 0.86) with the SIR of common bile duct for the detection of patients with Child-Pugh class B or C; (100%, 87%, 0.94) with the SIR of cystic duct for MELD score (>10); (65%, 76%, 0.70) with the SIR of common bile duct for APRI (>1.5). Conclusion: Gadoxetic-acid contrast enhancement of cystic duct and common bile duct could be used as biomarkers to assess liver function.

    Acute pancreatitis is mostly caused by gallstones or sludge. Early decompression of the biliary tree by endoscopic retrograde cholangiography (ERC) with sphincterotomy may improve outcome in these patients. Whereas current guidelines recommend early ERC in patients with concomitant cholangitis, early ERC is not recommended in patients with mild biliary pancreatitis. Evidence on the role of routine early ERC with endoscopic sphincterotomy in patients without cholangitis but with biliary pancreatitis at high risk for complications is lacking. We hypothesize that early ERC with sphincterotomy improves outcome in these patients. The APEC trial is a randomized controlled, parallel group, superiority multicenter trial. Within 24 hours after presentation to the emergency department, patients with biliary pancreatitis without cholangitis and at high risk for complications, based on an Acute Physiology and Chronic Health Evaluation (APACHE-II) score of 8 or greater, Modified Glasgow score of 3 or greater, or serum C-reactive protein above 150 mg/L, will be randomized. In 27 hospitals of the Dutch Pancreatitis Study Group, 232 patients will be allocated to early ERC with sphincterotomy or to conservative treatment. The primary endpoint is a composite of major complications (that is, organ failure, pancreatic necrosis, pneumonia, bacteremia, cholangitis, pancreatic endocrine, or exocrine insufficiency) or death within 180 days after randomization. Secondary endpoints include ERC-related complications, infected necrotizing pancreatitis, length of hospital stay and an economical evaluation. The APEC trial investigates whether an early ERC with sphincterotomy reduces the composite endpoint of major complications or death compared with conservative treatment in patients with biliary pancreatitis at high risk of complications.

    Full Text Available CLINICAL CASE A 70-year old woman was admitted to our hospital because of fever, asthenia and a suspected stroke. Her medical history showed a congenital cardiopathy (Patent Foramen Ovale, PFO. Skin and oral mucosa pigmentation, orthostatic hypotension, hypoglycemia and hyponatriemia arose the suspect of Addison’s disease. The diagnosis was confirmed by the evaluation of basal levels of plasma ACTH and serum cortisol, and serum cortisol levels after ACTH stimulation. Abdominal CT scan showed atrophy and calcification of adrenal glands. CONCLUSIONS In most cases, Addison’s disease is provoked by autoimmune destruction of the adrenal cortex; however, in our reported patient, tuberculosis could be a possible cause.

    Schistosomiasis is a disease caused by blood trematodes affecting man and animals that represents an important human health and veterinary problem. Main damages caused by this infection are a consequence of the host inflammatory reaction against the parasite eggs trapped inside the liver. Despite that the hepatic pathology of schistosomiasis is very well known, there are no specific studies dealing with the schistosome infection effects on the biliary function. The purpose of this work was to analyse the changes induced by Schistosoma bovis infection in the biliary proteome. For this, whole gallbladders from S. bovis-infected and non-infected mice were dissected, homogenized and fractionated by differential centrifugation. The resulting protein fractions were resolved by SDS-PAGE, the gels were sliced, and the gel pieces analysed by LC-MS/MS. Altogether, we identified 1937 proteins, which were classified according to their "protein class" and "molecular function", and then subjected to an "Enrichment analysis". The differences found in gallbladder proteomes between S. bovis-infected and non-infected mice are analysed. We show that chronic schistosome infections cause significant changes in the biliary proteome that may produce physiological alterations and affect the therapeutic actions of drugs when administered to human patients and animals with schistosomiasis. To identify the changes induced by the schistosome infection in bile protein composition, and therefore in bile function, we compared the proteome of the gallbladders collected from non-infected healthy mice and from mice infected with S. bovis during 4months. For this, gallbladders from both groups of mice were homogenized and these homogenates were fractionated by serial centrifugation and acrylamide gel electrophoresis. The proteins were in gel digested and analysed by LC-MS/MS for identification. The present work reports the first data on the proteome of the mouse gallbladder and provides a

    Full Text Available Altered extrahepatic bile ducts, gut, and cardiovascular anomalies constitute the variable phenotype of biliary atresia (BA.To identify potential susceptibility loci, Caucasian children, normal (controls and with BA (cases at two US centers were compared at >550000 SNP loci. Systems biology analysis was carried out on the data. In order to validate a key gene identified in the analysis, biliary morphogenesis was evaluated in 2-5-day post-fertilization zebrafish embryos after morpholino-antisense oligonucleotide knockdown of the candidate gene ADP ribosylation factor-6 (ARF6, Mo-arf6.Among 39 and 24 cases at centers 1 and 2, respectively, and 1907 controls, which clustered together on principal component analysis, the SNPs rs3126184 and rs10140366 in a 3' flanking enhancer region for ARF6 demonstrated higher minor allele frequencies (MAF in each cohort, and 63 combined cases, compared with controls (0.286 vs. 0.131, P = 5.94x10-7, OR 2.66; 0.286 vs. 0.13, P = 5.57x10-7, OR 2.66. Significance was enhanced in 77 total cases, which included 14 additional BA genotyped at rs3126184 only (p = 1.58x10-2, OR = 2.66. Pathway analysis of the 1000 top-ranked SNPs in CHP cases revealed enrichment of genes for EGF regulators (p<1 x10-7, ERK/MAPK and CREB canonical pathways (p<1 x10-34, and functional networks for cellular development and proliferation (p<1 x10-45, further supporting the role of EGFR-ARF6 signaling in BA. In zebrafish embryos, Mo-arf6 injection resulted in a sparse intrahepatic biliary network, several biliary epithelial cell defects, and poor bile excretion to the gall bladder compared with uninjected embryos. Biliary defects were reproduced with the EGFR-blocker AG1478 alone or with Mo-arf6 at lower doses of each agent and rescued with arf6 mRNA.The BA-associated SNPs identify a chromosome 14q21.3 susceptibility locus encompassing the ARF6 gene. arf6 knockdown in zebrafish implicates early biliary dysgenesis as a basis for BA, and also

    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.

    Purpose: To analyze outcome and predictive factors for patient survival and patency rates of unresectable malignant biliary obstruction treated with percutaneous transhepatic insertion of metal stents. Materials and Methods: This is a retroselective analysis of 130 patients treated in one interventional radiological center with data collected from patient records and by telephone interviews. The procedure-related data had been prospectively documented in a computer data base. The Kaplan-Meier analysis was performed for univariate and multivariate comparison of survival and patency rates with the log-rank test used for different tumor types. Predictive factors for survival and 30-day mortality were analyzed by a stepwise logistic regression. Results: Underlying causes of malignant biliary obstructions were cholangiocarcinoma in 50, pancreatic carcinoma in 29, liver metastases in 27, gallbladder carcinoma in 20, and other tumors in 4 patients. The technical success rate was 99%, the complication rate 27% and the 30-day mortality 11%. Primary patency rates (406 days with a median of 207 days) did not differ significantly for different tumor types. The survival rates were significantly (p = 0.03 by log-rank test) better for patients with cholangiocarcinoma than for patients with pancreatic carcinoma and liver metastases. Multiple regression analysis revealed no predictive factor for patient survival and 30-day mortality. Conclusion: Percutaneous transhepatic insertion of metal biliary endoprostheses offers a good initial and long-term relief of jaundice caused by malignant biliary obstruction. Although survival rates for patients with cholangiocarcinoma are better than for other causes of malignant biliary obstruction, a clear predictive factor is lacking for patients undergoing palliative biliary stent insertion.

    We report a case of intrahepatic cholangiocarcinoma with biliary lithiasis arising 47 years after surgery for a congenital biliary dilatation (CBD). A 62-year-old woman was admitted for the investigation of a liver tumor. She had undergone a choledochoduodenostomy at the age of 15 years for CBD and resection of an extrahepatic bile duct with choledochojejunostomy because of cholangitis at the age of 55 years. An enhanced computed tomography (CT) revealed a liver tumor 50 mm in diameter in the S6 region with surrounding lymph node swelling and intrahepatic metastatic lesions in the S8 region. A drip infusion cholangiographic CT showed biliary lithiases in the left liver. An extended right hepatectomy and lymph node dissection was considered but was abandoned because of suspicions of liver functional insufficiency as a result of biliary lithiasis. She underwent biliary lithotomy through a percutaneous transhepatic cholangioscopy and subsequent systemic chemotherapy.

    Measuring corneal biomechanical properties may help detect keratoconus suspect corneas and eliminate the risk of ectasia after LASIK. Data of 504 eyes separated into three groups were retrospectively reviewed: normal (n = 252), keratoconus suspect (n = 80), and keratoconus (n = 172). Corneal hysteresis (CH) and corneal resistance factor (CRF) were measured with an ocular biomechanics analyzer. Mean corneal hysteresis was 10.6 +/- 1.4 (SD) mm Hg in the normal group, compared with 10.0 +/- 1.6 mm Hg in the keratoconus suspect group and 8.1 +/- 1.4 mm Hg in the keratoconus group. The mean CRF was 10.6 +/- 1.6 mm Hg in the normal group compared with 9.7 +/- 1.7 in the keratoconus suspect group and 7.1 +/- 1.6 mm Hg in the keratoconus group. Mean CH and CRF were significantly different between the three groups (P corneas. Analyzing signal curves obtained with the biomechanics analyzer may provide additional valuable information for selecting qualified patients for refractive surgery.

    An important group of suspected illegal cosmetics consists of skin bleaching products, which are usually applied to the skin of the face, hands and décolleté for local depigmentation of hyper pigmented regions or more importantly, for a generalized reduction of the skin tone. These cosmetic products are suspected to contain illegal active substances that may provoke as well local as systemic toxic effects, being the reason for their banning from the EU market. In that respect, illegal and restricted substances in cosmetics, known to have bleaching properties, are in particular hydroquinone, tretinoin and corticosteroids. From a legislative point of view, all cosmetic products containing a prohibited whitening agent are illegal and must be taken off the EU market. A newly developed screening method using ultra high performance liquid chromatography-time off flight-mass spectrometry allows routine analysis of suspected products. 163 suspected skin whitening cosmetics, collected by Belgian inspectors at high risk sites such as airports and so-called ethnic cosmetic shops, were analyzed and 59% were classified as illegal. The whitening agents mostly detected were clobetasol propionate and hydroquinone, which represent a serious health risk when repeatedly and abundantly applied to the skin.

    Full Text Available In this paper we describe the causes, patterns of presentation, and management of obstructive uropathy in Sudanese patients in a retrospective multi-center audit. All patients who presented with obstructive uropathy during 2005 were included in this study. All of the patients were subjected to serial investigations including imaging and tests of renal function. Diversion, stenting, and/or definitive surgery were performed in order to relieve the obstruction. Five hundred twenty patients were diagnosed with obstructive uropathy during this period; 345 (66% patients presented with chronic obstruction and 175 (34% with acute obstruction. Of the study patients, 210 (40% presented with significant renal impairment; 50 (23% of them required emergent dialysis. The patterns of clinical presentation of the obstructed patients included pain at the site of obstruction in 48%, lower urinary tract symptoms in 42%, urine retention in 36.5%, mass effect in 22%, and anuria in 4%. Patients in the pediatric age group constituted 4% of the total. The common causative factors of obstruction included congenital urethral valves, pelvi-ureteral junction obstruction, urolithiasis, and iatrogenic trauma, especially in the obstetric practice. Renal function was completely recovered with early management in 100% of patients with acute obstruction and was stabilized in 90% of patients with chronic obstruction. Four patients were diagnosed with end-stage renal failure; two of them were transplanted. The mortality rate in this study was less than 0.3%.

    Full Text Available Severe injuries of biliary or pancreatic ducts are associated with significant morbidity and mortality. Severe bile duct injuries such as major biliary leaks, complete transection, or complete occlusion of bile ducts can be grouped under the term complex bile duct injuries (CBDI. In the spectrum of pancreatic duct injuries, disconnected pancreatic duct syndrome (DPDS represents the most severe form and most often occurs after a severe episode of acute pancreatitis. Treatment of these complex injuries is quite challenging and for many years surgical management has been considered the treatment of choice. However, in the past few years, some studies have reported the successful management of CBDI or DPDS using endoscopic procedures alone or in combination with a percutaneous approach. In this review, we detail the endoscopic or combined endoscopic/percutaneous treatment possibilities for CBDI and DPDS.

    Full Text Available Marcus S Noel, Aram F Hezel James P Wilmot Cancer Center, University of Rochester, Rochester, NY, USA Abstract: Biliary tract cancer (BTC is a group of relatively rare tumors with a poor prognosis. The current standard of care consists of doublet chemotherapy (platinum plus gemcitabine; however, even with cytotoxic therapy, the median overall survival is less than 1 year. The genetic basis of BTC is now more clearly understood, allowing for the investigation of targeted therapy. Combinations of doublet chemotherapy with antiepidermal growth factor receptor agents have provided modest results in Phase II and Phase III setting, and responses with small molecule inhibitors are limited. Moving forward as we continue to characterize the genetic hallmarks of BTC, a stepwise, strategic, and cooperative approach will allow us to make progress when developing new treatments.

    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. © 2014 Blackwell Verlag GmbH.

  3. Primary Biliary Cirrhosis Is a Generalized Autoimmune Epithelitis

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available 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.

    Full Text Available 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.

    2016-05-01

    Full Text Available Objectives: Several endoscopic techniques have been proposed for the management of post-sphincterotomy bleeding. Lately, self-expandable metal stents deployment has gained popularity especially as a rescue therapy when other endoscopic techniques fail. Methods-results: We report the case report of a massive post-sphincterotomy bleeding in a patient with a self-expandable metal stent in the biliary tree. Despite the presence of a correctly positioned self-expandable metal stent, a new endoscopic session was required to control the bleeding. Conclusions: Self-expandable metal stent may be useful to manage post-endoscopic sphincterotomy bleeding. However, up to now there is no specifically designed self-expandable metal stent for such complication. Large new designed self-expandable metal stent may be a useful tool for biliary endoscopist.

    The records of 242 patients, operated consecutively for biliary lithiasis, were analyzed to determine the reliability of oral cholecystography (OCG), ultrasonography (US), and HIDA in detecting biliary calculi. Preoperative interpretations were correlated to operative findings. OCG obtained in 138 patients was accurate in 92%. US obtained in 150 was correct in 89%. The accuracy of HIDA was 92% in acute and 78% in chronic cholecystitis. Intraoperative cholangiography (IOC) done in 173 patients indicated the need for exploratory choledochotomy in 24; 21 had choledocholithiasis. These observations suggest that OCG and US are very accurate, but not infallible, in detecting cholelithiasis. US should be done first; when doubt persists, the addition of OCG allows the preoperative diagnosis of gallstones in 97% of the cases. HIDA is highly accurate but not infallible in detecting acute calculous cholecystitis. IOC is very reliable in detecting choledocholithiasis; thus, its routine is justifiable.

    2008-01-01

    T-tube choledochotomy has been an established practice in common bile duct exploration for many years. Although bile leaks, biliary peritonitis, and long-term postoperative strictures have been reported and are directly associated with the placement or removal of the T-tube, the severity of these complications may often be underestimated by surgeons. We present the case of a 31-year-old male patient who developed biliary peritonitis and septic shock after removal of a T-tube and illustrate one of the catastrophic events that may follow such procedures. Literature shows that these complications may occur more frequently and have higher morbidity and mortality than other less invasive procedures. This article reviews the advances in laparoscopic and endoscopic techniques, which provide alternative therapeutic approaches to choledocholithiasis and allow the surgeon to avoid having to perform a choledochotomy with T-tube drainage.

    Hu, Bing; Horrow, Mindy M

    2016-09-01

    Biliary cast syndrome (BCS) consists of mass-like hardened collections of inspissated bile and sloughed biliary mucosa filling the intrahepatic and/or extrahepatic bile ducts, which show an alternating pattern of dilatation and stricture. It is a rare but serious complication of liver transplantation frequently necessitating repeated percutaneous, endoscopic or surgical stent placements, and cast retrieval. Although not typically considered as the modality of choice for BCS compared with magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography, ultrasound can be quite useful for this diagnosis. This article reviews the sonographic appearance of BCS in postliver transplant patients and correlates with other imaging modalities including computed tomography, MRCP, and endoscopic retrograde cholangiopancreatography. Also reviewed are other intrahepatic pathologies that mimic the appearance of BCS on ultrasound.

    2012-01-01

    Full Text Available Primary biliary cirrhosis (PBC is an autoimmune liver disease characterized by immune mediated biliary damage and frequent appearance of autoantibodies against mitochondrial enzymes. There is almost no useful animal model that is globally recognized and routinely used, however, several unique animal models manifested the characteristic clinical and pathological features of human PBC within the last 5 years. Herein, we compare the pathological features of previously reported and newly introduced novel animal models of PBC. Knowledge and understanding of the strengths and the limitations of each animal model have led to the development of promising therapies and novel tools to characterize these clinical conditions. Moreover, suitability of the model for the intended purpose should be confirmed by further research and analysis.

We present a 9-year-old boy with biliary cystadenoma, diagnosed by MRI using a new liver-specific contrast agent (gadoxetic acid) that is eliminated by the biliary system. The images clearly demonstrate the communication between the multiloculated cystic mass and the biliary tree, suggesting the possibility of biliary cystadenoma. Due to the malignant potential of a cystadenoma, the lesion was resected. The resection was complete and the postoperative course was uneventful. (orig.)

    Primary biliary cirrhosis is characterised by the presence of antimitochondrial antibodies which are directed against components of mitochondrial dehydrogenase complexes. The specificity of antimitochondrial antibodies for primary biliary cirrhosis as detected by immunoblotting was investigated. Commercially available preparations of pyruvate and oxo-glutarate dehydrogenases and beef-heart mitochondria were used as source of antigens. Sera from 47 primary biliary cirrhosis patients (46 of who...

    Biliary atresia is an inflammatory fibrosclerosing lesion of the bile ducts that leads to biliary cirrhosis and is the most frequent indication for liver transplantation in children. The pathogenesis of biliary atresia is not known; one theory is that of a virus-induced, subsequent autoimmune-mediated injury of bile ducts. The aim of this study was to determine whether autoreactive T cells and autoantibodies specific to bile duct epithelia are present in the rotavirus (RRV)- induced murine mo...

    Full Text Available Liver transplantation has become the effective therapeutic method for end-stage liver disease, but the incidence of biliary complications after liver transplantation remains high. With an increasing number of liver transplantation procedures from donation after cardiac death (DCD, it is necessary to investigate the risk factors for biliary complications after liver transplantation from DCD and enhance our understanding of such risk factors in order to reduce biliary complications after liver transplantation from DCD.

    Twenty four patients with malignant bile duct obstruction were treated with intraluminal radiotherapy using iridium-192 wire inserted through an endoscopically placed nasobiliary catheter. Biliary drainage after treatment was maintained by an endoprosthesis. The median dose of intraluminal radiotherapy was 6000 cGy; two patients with cholangiocarcinoma were given a second course because of disease extension; four patients with pancreatic carcinoma received additional external irradiation (3000 cGy). There was one early death from a cerebrovascular accident (30 day mortality, 4.2%). Cholangitis (30%) was the major early complication and stent blockage (40%) the major late complication; there were no complications directly attributable to radiotherapy. The median survival for patients with pancreatic carcinoma was 250 days and for cholangiocarcinoma, 300 days. This method is technically feasible and may prove safer than the transhepatic technique. The ability of intraluminal irradiation to improve palliation or lengthen survival in patients with malignant bile duct obstruction remains uncertain.

    Full Text Available Abstract Introduction Bouveret's syndrome is a clinically distinct form of gallstone ileus caused by the formation of a fistula between the biliary tract and duodenum. This case reinforces the need for early recognition and treatment of Bouveret's syndrome, as it is associated with high morbidity and mortality rates. Case presentation An 82-year-old Caucasian woman presented with signs and symptoms of small bowel obstruction. Her laboratory workup showed elevated alkaline phosphatase and amylase levels. Computed tomography of her abdomen revealed pneumobilia, a choledochoduodenal fistula and a gallstone obstructing her distal duodenum. The impacted gallstone could not be extracted endoscopically, so our patient underwent open enterolithotomy successfully. However, the postoperative course was complicated by myocardial infarction, respiratory failure and disseminated intravascular coagulation. She died 22 days after surgery, secondary to cardiopulmonary arrest. Conclusion This case clearly highlights the considerable morbidity and mortality associated with Bouveret's syndrome.

    Percutaneous biliary drainage and stenting (PTBD) for palliation of malignant obstructive jaundice has evolved to a safe and effective technique. PTBD is equally effective for treatment of distal and proximal bile obstruction. Metal self-expandable stents have proved superior to plastic stents and should therefore be used. Technical success is >90% en clinical success is >75% in all major series. There are a considerable number of complications, but most can be treated conservatively and procedure-related mortality is <2% in most series. Thirty-day mortality after PTBD is >10% in many series, but this is largely due to the underlying disease. About 10-30% of patients will have recurrent jaundice at some point in their disease after PTBD and require re-intervention. (orig.)
