    Extrahepatic biliary cystadenoma is a rare benign lesion with malignant potential. Fewer than 100 cases have been reported in the literature. The most common clinical presentation is obstructive jaundice. Frank cholangitis is extremely rare. The authors report a case of extrahepatic biliary cystadenoma in a 55-year-old woman who presented with recurrent episodes of cholangitis.

    The technique of non-surgical percutaneous transhepatic biliary drainage has been improved recently. Combined internal and external drainage of bile was enabled by manipulation of a guide wire and a drainage catheter through the stenosed or obstructed section of the extrahepatic biliary ducts. Experience have been gained concerning internal drainage of bile by percutaneous transhepatic insertion of an endoprosthesis for some years now.

    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.

    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.

    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...

    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.

    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

    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.

    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.

    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.

    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.

    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

    Discussion: 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.

    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.

    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.

    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.

    2012-12-15

    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.

    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.

    Surgical resection of extrahepatic biliary malignancies has been increasingly centralized at high-volume tertiary care centers. While this has improved outcomes overall, increased travel burden has been associated with worse survival for many other malignancies. We hypothesized that longer travel distances are associated with worse outcomes for these patients as well. Data was analyzed from the US Extrahepatic Biliary Consortium database, which retrospectively reviewed patients who received resection of extrahepatic biliary malignancies at 10 high-volume centers. Driving distance to the patient's treatment center was measured for 1025 patients. These were divided into four quartiles for analysis: < 24.5, 24.5-57.2, 57.2-117, and < 117 mi. Cox proportional hazard models were then used to measure differences in overall survival. No difference was found between the groups in severity of disease or post-operative complications. The median overall survival in each quartile was as follows: 1st = 1.91, 2nd = 1.60, 3rd = 1.30, and 4th = 1.39 years. Patients in the 3rd and 4th quartile had a significantly lower median household income (p = 0.0001) and a greater proportion Caucasian race (p = 0.0001). However, neither of these was independently associated with overall survival. The two furthest quartiles were found to have decreased overall survival (HR = 1.39, CI = 1.12-1.73 and HR = 1.3, CI = 1.04-1.62), with quartile 3 remaining significant after multivariate analysis (HR = 1.45, CI = 1.04-2.0, p = 0.028). Longer travel distances were associated with decreased overall survival, especially in the 3rd quartile of our study. Patients traveling longer distances also had a lower household income, suggesting that these patients have significant barriers to care.

    Extrahepatic portal vein obstruction (EHPVO) is characterized by features of recent thrombosis or portal hypertension with portal cavernoma as a sequel of portal vein obstruction. Imaging of spleno-portal axis is the mainstay for the diagnosis of EHPVO. The aim of this study is to analyze the role of imaging in the preoperative assessment of the portal venous system in children with EHPVO. A hospital-based cross-sectional study was conducted on twenty children with EHPVO aged between 1 and 18 years over a period of 1 year. The children were evaluated clinically, followed by upper gastrointestinal endoscopy. Radiological assessment included imaging of the main portal vein, its right and left branches, splenic vein, and superior mesenteric vein using color Doppler ultrasonography (CDUSG) and magnetic resonance portovenogram (MRP). Evidence of portal biliopathy, status of collaterals, and possible sites for portosystemic shunt surgery were also examined. All the patients presented in chronic stage with portal cavernoma and only one patient (5%) had bland thrombus associated with cavernoma. The CDUSG and MRPs had a sensitivity of 66.6-90% and 96.7% and specificity of 91.5% and 98.3% respectively with regard to the assessment of the extent of thrombus formation and flow in the portal venous system. Both the modalities were found to be complementary to each other in preoperative assessment of EHPVO. However, the sensitivity of MRP was slightly superior to CDUSG in detecting occlusion and identifying portosystemic collaterals and dilated intrahepatic biliary radicals. Results of the present study indicate that MRP is well suited and superior to CDUSG in the preoperative imaging of patients with EHPVO.

    Bile duct injury is a rare but serious complication of minimally invasive cholecystectomy. Traditionally, intraoperative cholangiogram has been used in difficult cases to help delineate anatomical structures, however, new imaging modalities are currently available to aid in the identification of extrahepatic biliary anatomy, including near-infrared fluorescent cholangiography (NIFC) using indocyanine green (ICG).1-5 The objective of the study was to evaluate if this technique may aid in safe dissection to obtain the critical view. Thirty-five consecutive multiport robotic cholecystectomies using NIFC with ICG were performed using the da Vinci Firefly Fluorescence Imaging System. All patients received 2.5 mg ICG intravenously at the time of intubation, followed by patient positioning, draping, and establishment of pneumoperitoneum. No structures were divided until the critical view of safety was achieved. Real-time toggling between NIFC and bright-light illumination was utilized throughout the case to define the extrahepatic biliary anatomy. ICG was successfully administered to all patients without complication, and in all cases the extrahepatic biliary anatomy was able to be identified in real-time 3D. All procedures were completed without biliary injury, conversion to an open procedure, or need for traditional cholangiography to obtain the critical view. Specific examples of cases where x-ray cholangiography or conversion to open was avoided and NIFC aided in safe dissection leading to the critical view are demonstrated, including (1) evaluation for aberrant biliary anatomy, (2) confirmation of non-biliary structures, and (3) use in cases where the infundibulum is fused to the common bile duct. NIFC using ICG is demonstrated as a useful technique to rapidly identify and aid in the visualization of extrahepatic biliary anatomy. Techniques that selectively utilize this technology specifically in difficult cases where the anatomy is unclear are demonstrated in order

    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.

    Extrahepatic biliary tract and pancreatic cancer are relatively rare malignant tumors. Prognosis is usually poor and surgical treatment gives a chance of cure in nonadvanced cases only. Evaluation of efficacy and toxicity of PEF regimen (cisplatin + epirubicin + 5 fluorouracil) in advanced extrahepatic biliary tract and pancreatic cancer. Chemotherapy regimen: cisplatin 20 mg/m2 i.v, epirubicin 25 mg/m2 i.v., 5 fluorouracil was given in 28 patients with advanced extrahepatic biliary tract and pancreatic cancer at the Clinic of Oncology of the Collegium Medicum of the Jagiellonian University in Krakow in years 1997 to 2004. The treatment was repeated every 4 weeks up to 6 cycles. 12 patients with extrahepatic biliary tract cancer and 16 patients with pancreatic cancer were treated. Median time from the diagnosis to death was 8.8 months in patients with extrahepatic biliary tract and 8.7 months in patients with pancreatic cancer. 1-year survival was 25% and 16.7%, respectively. Hematological toxicity G 3 and G 4 occured in 5 patients (17.9% treated). Chemotherapy PEF seems to be an active and well tolerated regimen of palliative chemotherapy for advanced extrahepatic biliary tract carcinomas and pancreas carcinomas. Overall survival in the pancreatic cancer group is comparable to results obtained with gemcitabine monotherapy.

    Extrahepatic portal vein obstruction is a vascular disorder of liver, which results in obstruction and cavernomatous transformation of portal vein with or without the involvement of intrahepatic portal vein, splenic vein, or superior mesenteric vein. Portal vein obstruction due to chronic liver disease, neoplasm, or postsurgery is a separate entity and is not the same as extrahepatic portal vein obstruction. Patients with extrahepatic portal vein obstruction are generally young and belong mostly to Asian countries. It is therefore very important to define portal vein thrombosis as acute or chronic from management point of view. Portal vein thrombosis in certain situations such as liver transplant and postsurgical/liver transplant period is an evolving area and needs extensive research. There is a need for a new classification, which includes all areas of the entity. In the current review, the most recent literature of extrahepatic portal vein obstruction is reviewed and summarized.

    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.

    Biliary bipolar radiofrequency ablation (RFA) is a new treatment for extrahepatic cholangiocarcinoma (CCA) currently under evaluation. The purpose of this study was to evaluate the safety, particularly biliary fistula occurrence, and the feasibility of biliary RFA in a homogeneous group of patients treated using the same RFA protocol. Twelve patients with inoperable or unresectable CCA were included in a bicentric case series study. After removal of biliary plastic stents, a radiofrequency treatment with a new bipolar probe (Habib™ EndoHBP) was applied. The energy was delivered by a RFA generator (VIO 200 D), supplying electrical energy at 350 kHz and 10 W for 90 s. At the end of the procedure, one or more biliary stents were left in place. Adverse events were assessed per-procedure and during follow-up visits. CCA was confirmed in all patients by histology (66%), locoregional evolution or metastatic evolution. The types of CCA were Bismuth I stage (N = 4), Bismuth II stage (N = 3), Bismuth III stage (N = 2) and Bismuth IV stage (N = 3). No serious adverse events occurred within 30 days following endoscopic treatment: One patient had a sepsis due to bacterial translocation on day 1 and another had an acute cholangitis on day 12 due to early stent migration. No immediate or delayed biliary fistula was reported. The ergonomics of the probe made treatment easy in 100 % of cases. Mean survival was 12.3 months. Endoscopic radiofrequency treatment of inoperable CCA appears without major risks and is feasible. No major adverse events or biliary fistula were identified.

    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 INTRODUCTION Basic liver function test is a part of preoperative evaluation of biliary lithiasis. It is seen in many worldwide reports about significant alterations of liver function both in pre and post-operative period. As a unique geographical placement and different dietary habit adopted by North East Indian population, this present study will stress upon the significance of alteration of liver function in biliary lithiasis cases. MATERIALS AND METHODS A total of 400 patients of extrahepatic biliary lithiasis, subjected to either open or laparoscopic procedure, are prospectively analysed by examining LFTs pre-operatively, the 1 st day after surgery and on completion of 4 weeks in a tertiary teaching hospital of North East India. RESULTS Alteration in AST, ALT, GGT were seen with minor changes in serum bilirubin and proteins on 1 st post-operative day noticed in two-third of the patients. After 4 weeks, these tests came down to almost their normal values. CONCLUSION Though mild-to-moderate alterations of LFTs are seen during initial period, after 4 weeks, values came to their base level.

    Minimal hepatic encephalopathy (MHE) is associated with poor quality of life and increased work disability in cirrhotic patients. Its prevalence in extrahepatic portal vein obstruction (EHPVO) is not known. We studied the prevalence of MHE in EHPVO patients and utility of critical flicker frequency (CFF) for diagnosing MHE. Thirty-four EHPVO patients with a history of variceal bleed (age 23.2 +/- 11.2 yr, M:F 22:12) diagnosed by either Doppler US or MR angiography, which demonstrated portal vein obstruction and/or portal vein cavernoma, were evaluated by psychometry (number connection tests A, B or figure connection tests A, B) and P300 auditory event-related potential (P300ERP). CFF was also evaluated. MHE was diagnosed by abnormal psychometry (>2 standard deviation [SD]) and/or P300ERP (>2.5 SD). Prevalence of MHE (N = 12) was 35.3%. Of 34 patients, P300ERP was abnormal (380.0 +/- 28.9 msec) in 11 (32%), psychometry in 9 (26.4%), both P300ERP and psychometry in 8 (23.5%), and CFF psychometry and 7 (64%) with abnormal P300ERP had CFF below 38 Hz. CFF had sensitivity (75%), specificity (96%), positive predictive value (86%), negative predictive value (93%), and diagnosis accuracy of 91% when compared to patients with both abnormal psychometry and P300ERP. The venous ammonia level was higher in patients with MHE (83.1 +/- 29.7 vs 44.7 +/- 16.1 micromol/L, P psychometry and P300ERP. However, in view of the relatively low number of patients with MHE, the usefulness of CFF in this setting awaits confirmatory studies.

    To assess the prevalence of concurrent extrahepatic autoimmune diseases in patients with autoimmune hepatitis (AIH)/primary biliary cirrhosis (PBC) overlap syndrome and applicability of the 'mosaic of autoimmunity' in these patients. The medical data of 71 AIH/PBC overlap patients were evaluated for associated autoimmune diseases. In the study population, 31 (43.6%) patients had extrahepatic autoimmune diseases, including autoimmune thyroid diseases (13 patients, 18.3%), Sjögren syndrome (six patients, 8.4%), celiac disease (three patients, 4.2%), psoriasis (three patients, 4.2%), rheumatoid arthritis (three patients, 4.2%), vitiligo (two patients, 2.8%), and systemic lupus erythematosus (two patients, 2.8%). Autoimmune hemolytic anemia, antiphospholipid syndrome, multiple sclerosis, membranous glomerulonephritis, sarcoidosis, systemic sclerosis, and temporal arteritis were identified in one patient each (1.4%). A total of 181 autoimmune disease diagnoses were found in our patients. Among them, 40 patients (56.4%) had two, 23 (32.3%) had three, and eight (11.3%) had four diagnosed autoimmune diseases. A large number of autoimmune diseases were associated with AIH/PBC overlap patients. Therefore, extended screening for existing autoimmune diseases during the routine assessment of these patients is recommended. Our study suggests that the concept of 'mosaic of autoimmunity' is a valid clinical entity that is applicable to patients with AIH/PBC overlap syndrome.

    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.

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.

    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.

    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.

    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.)

    Full Text Available Renal biopsy in patients with nephrotic syndrome helps to establish the pathological diagnosis and subsequent treatment. In certain circumstances, biopsies are difficult to obtain because of the risk of bleeding. We report a case where renal biopsy was obtained through the transjugular route in a patient who had nephrotic syndrome with extrahepatic portal venous obstruction.

    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.

    Basing on a patient material consisting of 28 patients with tumours in the region of the extrahepatic bile ducts, the following criteria are examined which govern the demonstration of tumour obstructions by means of the computer tomogram: Extent of widening of the bile ducts, assessment of stenosis or complete obstruction of the bile ducts and demonstration of the structure of the tumorous tissue and of the tumorous infiltration into the adjacent tissues. Computerized tomography of this region can achieve a narrowing-down of the indications for an endoscopic or percutaneous visualization of the bile ducts, these being more severely invasive methods.

    Magnetic resonance cholangiopancreatography (MRCP) is often used for imaging of the biliary tree and is required by surgeons before liver transplantation. Advanced liver cirrhosis and ascites in patients however present diagnostic problems for MRCP. The aim of this study was to find out if the use of our negative per-oral contrast agent containing superparamagnetic iron oxide nanoparticles (SPIO) in MRCP is helpful for imaging of hepatobiliary tree in patients with liver cirrhosis. Forty patients with liver cirrhosis were examined on a 1.5 T MR unit using standard MRCP protocol. Twenty patients (group A) underwent MRCP after administration of per-oral SPIO contrast agent 30 min before examination. In group B, twenty patients were examined without per-oral bowel preparation. Ascites was present in eleven patients from group A and in thirteen patients in group B. Four radiologists analyzed MR images for visibility and delineation of the biliary tree. χ2 tests were used for comparison of the visibility of intrahepatic and extrahepatic biliary ducts in patients with and without ascites. Better extrahepatic biliary duct visualization and visibility of extraluminal pathologies in patients with ascites was proved after administration of SPIO contrast agent. No statistically significant difference between group A and B was found for visualization of extrahepatic biliary ducts in patients without ascites. Delineation of intrahepatic biliary ducts was independent on bowel preparation. Application of our negative per-oral SPIO contrast agent before MRCP improves the visualization of extrahepatic biliary ducts in patients with ascites which is helpful during the liver surgery, mainly in liver transplantation.

    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).

    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.

    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.

    We describe a patient with extrahepatic portal venous obstruction due to a giant hepatic hemangioma associated with Kasabach-Merritt syndrome. A 67-year-old woman presented with upper abdominal distension and appetite loss. The medical history was not relevant to the current disorder. Initial laboratory tests revealed the following: serum platelet count, 9.9 × 10⁴/µL; serum fibrinogen degradation products, 12 µg/mL; prothrombin time, 1.26; and serum fibrinogen, 111 mg/dL. Computed tomography demonstrated homogenous low-density areas, 15 cm in diameter, in the left lobe of the liver. Common hepatic arteriography revealed a hypervascular tumor with pooling of contrast medium in the delayed phase. The portal venous phase of supramesenteric arteriography revealed obstruction and cavernous transformation of the portal vein. We diagnosed extrahepatic portal venous obstruction due to a giant hepatic hemangioma associated with Kasabach-Merritt syndrome. Laparotomy was performed, and the liver was found to be markedly enlarged. After mobilization of the left lobe, left hepatectomy was performed with intermittent clamping. After resection, Doppler ultrasonography revealed recovery of the portal venous flow. The cavernous transformation shrank. Pathologic examination of the surgical specimen confirmed the presence of a giant benign hepatic cavernous hemangioma. The patient was discharged 16 days after operation. Laboratory data and complications improved after 2 months.

    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 Abstract Introduction Extra-hepatic biliary atresia (EHBA is an important cause of neonatal cholestasis. Several infectious agents have been proposed as etiologic factors such as Rotavirus and Reovirus. There is limited data on the role of Epstein Barr virus (EBV infection in EHBA, so we decided to study the presence of EBV virus in a series of 16 proven EHBA cases by Chromogenic in situ hybridization (CISH technique. Methods In the current study a total of 16 liver wedge biopsies of proven cases of EHBA were selected in a period of 4 years. CISH staining for EBV-encoded RNA (EBER transcript was performed. Results The review of H&E-stained slides of liver biopsies revealed fibrosis and marked ductular proliferation. In CISH-stained slides, EBV trace was observed in hepatocytes in two cases and in biliary epithelium in one case of EHBA. Discussion Considering the association of hepatitis with the Epstein-Barr virus in later life, it is likely that EBV hepatitis and its complications occur in the neonatal/perinatal period. Since EHBA is a relatively rare disease, a similar study on wedge biopsies of this number of proven cases of EHBA has not been performed to date. Current observation proposes the need for a study of larger series and employing other methods for confirming the etiologic role of EBV in EHBA cases.

    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 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.

    The clinicopathological significance of HER-1- and HER-2-overexpressions (OE) (HercepTest score 2+ or 3+) in biliary cancer and their relationship to the efficacy of adjuvant chemotherapy (ACT) were assessed. In 72 biliary cancer (28 gallbladder and 44 bile duct cancer), HER-1 and HER-2 were stained immunohistochemically in formalin-fixed, paraffin-embedded specimens. The ACT included uracil and tegafur (UFT)-based chemotherapies. Out of the 72 cancer, OE was observed in 31 specimens (43%) for HER-1 and 47 (65%) for HER-2. However, their OEs were not correlated with each other. HER-2-OE was inversely correlated with the clinical stage (p=0.0482). HER-1-OE was correlated with distant metastasis (p=0.0263), but not with the clinical stage. Neither the OE of HER-1 or HER-2, nor their co-expression, showed any significant effect in term of patient survival. In the HER-1-OE (-) patients, the survival rate of the ACT group was significantly higher than that of the surgery-alone (SA) group (p=0.0423), but in the HER-1-OE (+) patients, there was no statistical difference in survival rate between the ACT and the SA group. In contrast, HER-2-OE had no significant effect on the efficacy of ACT. Multivariate analysis also demonstrated that the histological grade and ACT were significant variables, but T, N, M and HER-1 and HER-2 were not significant variables. In conclusion, neither HER-1-OE or HER-2-OE were prognostic factors of the biliary cancer. However, HER-1-OE may be a useful marker for the indication of ACT.

  10. Early diagnosis of extrahepatic biliary atresia in an open-access medical system.

    Directory of Open Access Journals (Sweden)

    Justin Hollon

    Full Text Available INTRODUCTION: Biliary atresia (BA is the most common cause of cholestatic jaundice in infancy. Early diagnosis and surgical management, ideally before 60 days of age, result in improved outcomes. We aimed to determine the age at diagnosis of BA in the Military Health System (MHS and to compare the age at diagnosis by access to care models. We hypothesized that children with BA receiving primary care in military facilities have an earlier age at diagnosis due to decreased economic and access barriers. METHODS: Data for all Tricare enrollees born in fiscal years 2004-2008 with a diagnosis of BA were extracted from MHS databases. Non-parametric tests, Kaplan-Meier curves and log rank tests compared differences in age at diagnosis by type of primary care facility, gender, prematurity and presence of additional anomalies. RESULTS: 64 subjects were identified within the five year period. Median age at diagnosis was 40 days [range 1-189], with 67% diagnosed by 60 days and 80% by 90 days. 45 (70% received civilian primary care within the MHS. There was no difference in the median age at diagnosis between subjects in the MHS with civilian primary care vs. military primary care (37 days [1-188] vs. 46 days [1-189]; p=0.58. CONCLUSION: In the MHS, two-thirds of infants with biliary atresia are diagnosed prior to 60 days of life. Gender, prematurity or presence of additional anomalies do not affect the timing of diagnosis. Civilian and military primary care models within the MHS make timely diagnoses of biliary atresia at equivalent rates.

    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.

    Chronic liver disease causes a disruption of procoagulant and anticoagulant factors, resulting in a fragile state, prone to increased rates of both bleeding and thrombosis. Currently, there is limited literature describing the changes observed in pediatric liver disease and extrahepatic portal vein obstruction or shunt. This study aimed to describe the changes that occur in children with chronic liver disease and extrahepatic portal vein obstruction or shunt. We measured the concentration and activity of key procoagulant and anticoagulant factors in children with liver disease, children with extrahepatic portal vein obstruction or shunt, and healthy children. Children with severe liver disease had coagulopathic changes, including either decreased concentration or activity of factor II, factor V, and factor VII. Nineteen percent (8/42) of the cohort had significant bleeding. Thrombophilic changes were also observed, including decreased concentration or activity of protein C, protein S, and antithrombin and increased concentration and activity of factor VIII and Von Willebrand factor. Similar coagulation factor changes were observed in children with extrahepatic portal vein obstruction or shunt. There was a trend toward greater changes in coagulation factor activity compared to concentration. This study provides a detailed description of the changes in both the concentration and activity of coagulation factors in pediatric liver disease and extrahepatic portal vein obstruction or shunt. Interestingly, procoagulant and anticoagulant factors were deranged in portal vein obstruction or shunt to a similar degree as in liver disease. An improved understanding of the coagulation profile in the pediatric setting will contribute to the improved management of liver disease and extrahepatic portal obstruction or shunt.

    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.

    Mild cognitive and psychomotor deficit has been reported in patients with extra-hepatic portal vein obstruction. This prospective study was done to ascertain the presence of minimal hepatic encephalopathy by neuropsychological testing and its correlation with diffusion tensor imaging derived metrics, T1 signal intensity, brain metabolites in (1)H magnetic resonance spectroscopy, blood ammonia and critical flicker frequency in patients with extra-hepatic portal vein obstruction. Neuropsychological tests, critical flicker frequency, blood ammonia, diffusion tensor imaging, T1 signal intensity and (1)H magnetic resonance spectroscopy were determined in 22 extra-hepatic portal vein obstruction and 17 healthy children. Bonferroni multiple comparison post hoc analysis was done to compare controls with patient groups. Based on neuropsychological tests, 7/22 patients had minimal hepatic encephalopathy, and significantly increased Glx/Cr ratio, blood ammonia, mean diffusivity and globus pallidus T1 signal intensity with decreased critical flicker frequency in comparison to controls and in those without minimal hepatic encephalopathy. Cho/Cr, mI/Cr ratio and fractional anisotropy were unchanged in patient groups compared to controls. A significant inverse correlation of neuropsychological test with mean diffusivity, Glx/Cr ratio and blood ammonia and a positive correlation among mean diffusivity, blood ammonia and Glx/Cr ratio was seen. Extra-hepatic portal vein obstruction is a true hyperammonia model with porto-systemic shunting and normal liver functions that results in minimal hepatic encephalopathy in one-third of these children. Hyperammonia results in generalized low grade cerebral edema and cognitive decline as evidenced by increased Glx/Cr ratio, mean diffusivity values and abnormal neuropsychological tests.

    Minimal hepatic encephalopathy (MHE) leads to deterioration in patient quality of life and could be a marker for future episodes of clinical hepatic encephalopathy (HE) in liver cirrhosis. Whether MHE predicts HE in extrahepatic portal vein obstruction (EHPVO) is not known. We studied the incidence of overt HE in EHPVO patients with MHE. Consecutive patients (from October 2006 to July 2007) with a diagnosis of EHPVO were followed up at 3-month intervals. MHE was diagnosed by abnormal psychometry (>2 s.d.) and/or P300 auditory event-related potential (P300 ERP) (>2.5 s.d.), and HE was diagnosed as per West-Heaven criteria. Critical flicker frequency (CFF) was also measured at baseline and after 1 year. Thirty-two EHPVO patients (age, 23.2+/-10.8 years; M/F 22:10) were followed up for 1 year. Of 32 patients, P300 ERP was prolonged in 8 (25%) (371.8+/-13.9 ms), 9 (28%) had abnormal psychometric tests, and CFF was <38 Hz in 8 (25%) patients after a follow-up of 13.5+/-2.4 months. Of 12 patients who had MHE at baseline, 9 (75%) patients continued to have MHE, and in 3 (25%) patients it disappeared. One (5%) of the remaining 20 patients developed MHE during the follow-up. Venous ammonia level was higher in patients with MHE (79.7+/-17.0 micromol/l; range 33-124) compared with patients without MHE (46.6+/-19.8 micromol/l; range 24-78, P<0.001) on follow-up. Similarly, patients who had spontaneous shunts (n=10) had significantly higher venous ammonia levels (82.4+/-20.3 vs. 47.1+/-16.7 micromol/l; P=0.001) than those who had no shunt (n=22). Neither patients who had MHE nor those who did not have MHE at baseline developed HE. Seventy-five percent of extrahepatic portal vein obstruction patients with MHE continued to have MHE, and new-onset MHE developed in 5% over 1 year. In this small sample, patients with EHPVO and MHE did not progress to overt encephalopathy within the relatively short time frame studied.

    Full Text Available OBJETIVO: enfatizar a importância do diagnóstico precoce da atresia biliar extra-hepática e sua relação direta com o restabelecimento cirúrgico do fluxo biliar antes do segundo mês de vida, discutindo os diversos métodos complementares utilizados, objetivando selecionar os de maior evidência, evitando retardo diagnóstico e, conseqüentemente, piora do prognóstico. MÉTODO: pesquisa bibliográfica referente ao período de 1985 a 2001, no Medline e MdConsult, através das palavras-chaves: colestase neonatal, atresia biliar extra-hepática e hepatite neonatal. Também foram selecionados artigos nacionais e estrangeiros a partir da bibliografia das publicações consultadas e, quando necessário, para melhor entendimento do tema, opiniões emitidas em teses e livros-textos foram referidas. RESULTADOS: a revisão da bibliografia consultada permite afirmar que o diagnóstico precoce das AVBEH e tratamento cirúrgico para restabelecer o fluxo biliar até 60 dias de vida são fundamentais na obtenção de bons resultados. Entre os diversos métodos complementares de diagnóstico, a colangiografia por RM, US e a biópsia hepática são os que proporcionam os maiores índices de acerto. CONCLUSÕES: o encaminhamento de pacientes portadores de AVBEH para centros de referências no Brasil ainda é efetuado tardiamente, provavelmente pela falta de esclarecimento dos médicos de atenção primária, aliada às dificuldades burocráticas e tecnológicas. A experiência da Inglaterra em relação ao programa "Alerta Amarelo", permitiu que o número de crianças encaminhadas para tratamento cirúrgico antes dos 60 dias de vida aumentasse significativamente. Entre os métodos complementares, a colangiografia por RM, a US e a biópsia hepática deverão ser utilizados, dependendo dos recursos tecnológicos das unidades de diagnóstico.OBJECTIVE: to emphasize the importance of precocious diagnosis of extrahepatic biliary atresia and its direct

    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.

    Full Text Available Extrahepatic portal vein obstruction, although rare in children, is a significant cause of portal hypertension (PHT leading to life-threatening gastrointestinal bleeding in the pediatric age group. PHT may also lead to other complications such as hyperesplenism, cholangyopathy, ascites, and even hepatopulmonary syndrome and portopulmonary hypertension that may require organ transplantation. Herein we report the case of an asymptomatic 11-month-old infant wherein a hepatomegaly and cavernous transformation of the portal vein was detected by liver ultrasound. Neither signs of thrombosis in arteriovenous system, nor affectation of biliary tract were identified in the magnetic resonance imaging study. A significant enlargement of the caudate lobe of the liver was reported. No risk factors were detected. The differential diagnosis performed was extensive. Inherited thrombophilia and storage disorders were especially considered. Liver biopsy was normal. Upper gastrointestinal esophagogastroduodenoscopy detected two small varicose cords on the distal third of the esophagus. Finding a cavernous transformation of the portal vein with evidence of collateral circulation in such an early age is a challenging condition for professionals, since PHT may lead to severe complications during childhood and can compromise growth and development. Evidence-based guidelines for the management of PHT in adults have been published. However, follow-up and treatment of pediatric patients have not yet been standardized. Moreover, management of PHT in infants faces particular difficulties such as technical restrictions that could hinder their treatment.

    Extrahepatic biliary atresia (EHBA) is the most important cause of neonatal cholestasis. The validity of different diagnostic methods in the diagnosis of EHBA in developed countries has been presented elsewhere, but data from developing countries with low national incomes are scarce. The aim of this study was to investigate the relative accuracy and roles of abdominal ultrasonography, duodenal tube test (DTT), and liver biopsy in the diagnosis of EHBA in Serbia. The study included 156 infants with cholestasis admitted at the Mother and Child Health Care Institute. Data were collected according to the medical records observation technique. Extrahepatic biliary atresia was diagnosed in 72 of 156 infants with cholestasis. The frequency was insignificantly higher in females than in males (1.25:1). Most patients were diagnosed prior to 60 days of life (median 58, range 30-67). In a group of 156 infants with cholestasis, 109 had ultrasound, liver biopsy, duodenal tube test, and intraoperative cholangiography done. Liver biopsy confirmed surgical disease in 71/109 patients and denied it in 38/109 patients (sensitivity- Sn 98%, specificity- Sp 100%, diagnostic efficiency of test- DgEf 99.08%). Duodenal tube test had Sn 97%, Sp 72%, and DgEf 88.99%, and the ultrasound findings showed Sn 78%, Sp 81%, and DgEf 77.92%. Five-year survival rate after Kasai operation was 76%. A well-coordinated multidisciplinary approach is required in the assessment of suspected cases of biliary atresia. Histology examination of biopsy specimens is an integral part of the diagnostic algorithm and, therefore, plays a pivotal role in the diagnostic evaluation of this disease.

    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.

    The two cornerstones of management for Extrahepatic portal vein obstruction (EHPVO) are endotherapy and surgery [Porto-systemic shunts (PSS)/Mesorex bypass (MRB)]. Endotherapy is the mainstay of treatment for acute variceal bleed control and has also been used extensively for secondary prophylaxis till variceal eradication is achieved. However, long-term follow-up beyond endoscopic eradication of esophageal varices (EEEV) indicates that there are numerous delayed bleed and non bleed sequelae of EHPVO, which merit surgery as a definitive procedure to decompress the hypertensive portal venous system. While endotherapy obliterates natural porto-systemic collaterals in the gastroesophageal region, persistently raised portal pressures manifest as an increase in secondary isolated gastric varices, ectopic varices, portal hypertensive vasculopathy, issues related to massive splenomegaly, portal biliopathy, growth retardation and hence impaired quality of life (QOL). An ideal management strategy should address both bleed and non-bleed consequences of EHPVO and translate into a near normal QOL. Further, MRB has opened up new dimensions to the management philosophy of EHPVO. This review article critically evaluates the role of surgery and endotherapy based on available literature and authors' own experience.Surgery and endotherapy are complementary. However, with increasing duration of follow-up post EEEV, it is evident that there is resurgence in the role of surgery (PSS/MRB) as a single one time definitive procedure for alleviating all bleed and delayed non bleed sequelae of EHPVO.Surgery for EHPVO (PSS/MRB) should not be allowed to become a dying art and future generations of surgeons should continue to receive training in this specialized area of surgery.

    Background/Aims: Minimal hepatic encephalopathy (MHE) is common in patients with extrahepatic portal vein obstruction (EHPVO). There is no study on the treatment of MHE using lactulose in patients with EHPVO. Patients and Methods: Consecutive EHPVO patients were assessed by psychometric (number connection test (NCT-A and B), digit symbol test (DST), serial dot test (SDT), line tracing test (LTT)), and critical flicker frequency (CFF) at inclusion. Patients diagnosed as MHE were treated with lactulose and psychometric tests, CFF, and were reassessed after 3 months. Results: Of the 70 patients screened, the prevalence of abnormal psychometric test was as follows: NCT-A (41%), NCT-B (53%), DST (38%), SDT (40%), and LTT (44%). Thirty patients (43%) had two or more than two abnormal (>2 SD) psychometry tests. Lactulose improved MHE in 16/30 (53%) of patients after 3 months of treatment. Arterial ammonia decreased after lactulose treatment compared to baseline (83.7±19.1 vs. 65.1±19.3 μmol/l, P=0.001). A total of 9 (75%) of 12 patients with large spontaneous shunt and 7 (39%) of 18 patients without spontaneous shunt improved with lactulose (P=0.07). CFF in patients with MHE (n=30) was significantly lower than those without MHE (n=40) (38.1±2.4 vs. 41.5±3.1 Hz, P=0.01). CFF was less than 38 Hz in 21 (70%) of 30 patients before treatment and in 10 (33%) patients after lactulose therapy in MHE patients. All patients could tolerate lactulose without any significant side effects. Four patients (13%) developed transient diarrhea in whom dose needed reduction, 3 (10%) did not like its taste but have continued, and 2 (6%) developed abdominal bloating sensation. Conclusions: Lactulose is effective in the treatment of MHE in patients with EHPVO. PMID:22626795

    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.

    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

    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.

    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

    Full Text Available Abstract Background The clinico-surgical implication and successful management of a rare case of factor five (V deficiency with portal hypertension and hypersplenism due to idiopathic extra-hepatic portal venous obstruction is presented. Case presentation A 16-year old boy had gastro-esophageal variceal bleeding, splenomegaly and hypersplenism. During preoperative workup prolonged prothrombin time and activated partial thromboplastin time were detected, which on further evaluation turned out to be due to factor V deficiency. Proximal lieno-renal shunt and splenectomy were successfully performed with transfusion of fresh frozen plasma during and after the surgical procedure. At surgery there was no excessive bleeding. The perioperative course was uneventful and the patient is doing well on follow up. Conclusion Surgical portal decompressive procedures can be safely undertaken in clotting factor deficient patients with portal hypertension if meticulous surgical hemostasis is achieved at operation and the deficient factor is adequately replaced in the perioperative period.

    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 reson...

    Presence of retro-aortic left renal vein poses special challenge in creating spleno-renal shunt potentially increasing the chance of shunt failure. The technical feasibility and successful outcome of splenectomy with proximal spleno-renal shunt (PSRS) with retro-aortic left renal vein is presented for the first time. The patient was treated for portal hypertension and hypersplenism due to idiopathic extra-hepatic portal vein obstruction. A twenty year old male suffering from idiopathic extra-hepatic portal vein obstruction presented with bleeding esophageal varices, portal hypertensive gastropathy, asymptomatic portal biliopathy and symptomatic hypersplenism. As variceal bleeding did not respond to endoscopic and medical treatment, surgical portal decompression was planned. On preoperative contrast enhanced computed tomography retro-aortic left renal vein was detected. Splenectomy with proximal splenorenal shunt with retro-aortic left renal vein was successfully performed by using specific technical steps including adequate mobilisation of retro-aortic left renal vein and per-operative pressure studies. Perioperative course was uneventful and patient is doing well after 3 years of follow up. PSRS is feasible, safe and effective procedure when done with retro-aortic left renal vein for the treatment of portal hypertension related to extra-hepatic portal vein obstruction provided that attention is given to key technical considerations including pressure studies necessary to ensure effective shunt. Present case provides the first evidence that retro-aortic left renal vein can withstand the extra volume of blood flow through the proximal shunt with effective portal decompression so as to treat all the components of extra-hepatic portal vein obstruction without causing renal venous hypertension.

    To evaluate the clinical presentation, possible etiological factors, management and outcome of patients in our hospital with extrahepatic portal vein obstruction (EHPVO). This study included patients with EHPVO followed up in our department during last 10 years. Patients of cirrhosis with EHPVO were excluded. Patients' clinical presentation, etiology of EHPVO, management and outcome results were analyzed. Of 30 patients, 19 (67.9%) were males. Median age was 12 years. Of 14 patients who underwent liver biopsy 9 had histological activity index stage of 1/6. History of omphalitis and pulmonary tuberculosis was present in one case each. Of 22 patients with the available thrombophilia profile, nine patients had a deficiency of protein C, five patients had a deficiency of protein S, one each had reduced level S of anti-thrombin III and factor V mutation. The predominant presenting symptom was hematemesis (15 patients, 53.6%). Seven patients (25%) had splenomegaly. Three patients (10.7%) had no esophageal varices on endoscopy. Three patients underwent splenectomy due to severe pancytopenia. Endoscopic retrograde cholangipancreatography was performed in four patients (14.3%) due to portal biliopathy. Common bile duct stenting was performed in all four patients. Of them, one patient underwent splenorenal shunt operation for indication of hemobilia. One patient died at the age of 40 years, due to cholangitis and sepsis. Results from this study show that the anticoagulant deficiency is a common cause of EHPVO in our setup. Hematemesis is a common presenting symptom. Some of these patients have symptomatic portal biliopathy.

    Primary biliary cirrhosis (PBC) is associated to any systemic autoimmune disease (SAD), in particular systemic sclerosis (SSc). To investigate the prevalence of SAD in a cohort of patients with PBC, specifically the prevalence of SSc and its clinical subtypes, and determining the clinical and biological profile of patients with associated PBC and SSc. Observational study of 62 patients with PBC following a protocol that included an anamnesis and physical examination to detect the presence of SAD as well as a nailfold capillaroscopy and an immunological study with specific SSc autoantibodies. A comparative analysis was conducted between patients with isolated PBC and patients with PBC and an associated SAD. SAD was associated to PBC in 22 patients (35,4%), and SSc was the most frequent illness, identified in 13 cases (21%). Five patients (8%) without previous diagnosis of SAD fulfilled pre-scleroderma criteria, according to LeRoy and Medsger criteria. The presence of anticentromere antibodies (54,5% vs. 5%, P<.001) was the unique immunological determination identified more frequently in patients with PBC-SAD. The SSc suggestive capillary pattern was visualized in 11 patients (20,4%), mainly the slow pattern. No factors associated with greater morbi-mortality were identified in the PBC-SAD group. It does exist a subgroup of patients with PBC and clinical-biological features suggestive of an SAD, which advise a protocolized study to detect early the association to an SAD.

    2012-01-01

    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.

    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 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

    To determine the factors prognostics of early mortality in the malignant billary estenosis after the endoscopic derivation. The surgical, percutaneous or endoscopic derivation is the alternative of palliative treatment in the biliary obstruction unresectable. 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.

    Full Text Available Abnormal high signal in the globus pallidus on T1 weighted magnetic resonance imaging (MRI of the brain has been well described in patients with chronic liver disease. It may be related to liver dysfunction or portal-systemic shunting. We report a case of extra hepatic portal vein obstruction with portal hypertension and esophageal varices that presented with extra pyramidal features. T1 weighted MRI brain scans showed increased symmetrical signal intensities in the basal ganglia. Normal hepatic function in this patient emphasizes the role of portal- systemic communications in the development of these hyperintensities, which may be due to deposition of paramagnetic substances like manganese in the basal ganglia.

    Hyposplenism has been described in patients with alcoholic cirrhosis (AC). However, no data are available regarding hyposplenism in patients with non-alcoholic cirrhosis (NAC) and other forms of portal hypertension such as extrahepatic portal venous obstruction (EHPVO). The aim is to study the splenic functions in patients with AC, NAC, and EHPVO. Splenic functions were assessed consecutively in 22 patients with AC, 21 with NAC, and 23 with EHPVO. The tests included pitted red blood cells (RBC; %) and Howell-Jolly bodies in the peripheral smear. Pitted RBCs > 2% with or without the presence of Howell-Jolly bodies were taken as indicators of hyposplenism. The splenic function in each group was compared with age-matched controls. Hyposplenism was found in 10 (45.45%) patients with AC, six (28.57%) with NAC and one (4.34%) with EHPVO. The mean pitted RBCs were significantly increased in patients with AC (mean 4.93 +/- 1.36% vs control 1.22 +/- 0.17%, P 0.05). Howell-Jolly bodies were seen in only four patients. The mean pitted RBCs were significantly higher among patients who were actively consuming alcohol (9.14 +/- 3.35%) compared to those who abstained at least for more than 24 weeks (2.0 +/- 1.3%, P < 0.05). Hyposplenism is more common in AC patients, particularly those who are actively consuming alcohol compared with those who abstain. Patients with NAC have a lower incidence of hyposplenism, while in EHPVO patients, it is uncommon.

  10. Comparison of covered and uncovered self-expandable stents in the treatment of malignant biliary obstruction

    Full Text Available Background and objective: Drainage with metallic stents is the treatment of choice in malignant obstructive jaundice. 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.

    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.

    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.

    The aim of this study was to evaluate the effect of surgical portosystemic shunt (PSS) on the prevalence of minimal hepatic encephalopathy (MHE) in patients with extrahepatic portal venous obstruction. Forty-two children with extrahepatic portal venous obstruction (17 with surgical PSS, 25 without surgical shunt) and 20 healthy children were evaluated with blood ammonia (BA), psychometry, H magnetic resonance spectroscopy, critical flicker frequency (CFF), and diffusion tensor imaging. Serum tumor necrosis factor-α and interleukin-6 were measured in 10 patients and 8 controls. Patients with surgical PSS had significantly higher BA and glutamine/creatine on H-MR spectroscopy than those without surgical shunt. Both groups of patients had significantly higher BA and glutamate/creatine than controls. Myoinositol was reduced in patients with surgical PSS. MHE was present in 41% cases with and 32% cases without surgical PSS (p-ns). Raised mean diffusivity on diffusion tensor imaging signifying low-grade cerebral edema was seen only in MHE cases. Patients had significantly higher serum tumor necrosis factor-α and interleukin-6 levels than controls. CFF was abnormal in 5 of 15 patients with MHE. Patients with surgical PSS have significantly higher BA and Glx/creatine than those without surgical PSS. MHE prevalence was higher in surgically shunted than in the nonshunted patients, but the difference was not significant. Cerebral edema is present in patients with MHE. CFF has limited diagnostic utility for MHE in children.

    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.

    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.)

    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).

    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

    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.

    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.

    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

    Gastroenteropancreatic neuroendocrine tumors are known for their aggressiveness. Diagnosis of various bile duct pathologies, like biliar intraepithelial neoplasm, mixed adenoneuroendocrine carcinomas or small cell carcinomas, is challenging. This case report focuses on a rare case of a focal primary minute small cell carcinoma in the vicinity of the extrahepatic bile duct, presenting itself next to an extensive biliar intraepithelial neoplasm. This finding led to adjuvant chemotherapy, followed by major surgery. Therapeutic approach was based on CT and MRI scans but most importantly on immunohistochemistry and histological evaluation. Initially CR seemed achievable, but metastases were to be found rapidly. The authors want to underline the fact that major clinical decisions are based on sometimes tiny specimens; as literature shows it is absolutely advisable to use markers to differentiate the dignity of investigated areas. The authors call for keeping collision of tumors in mind and adding KOC staining and using it in a routine manner examining biliary duct lesions.

    Full Text Available Abstract Background There is currently no standard adjuvant therapy for patients with curatively resected extrahepatic biliary tract cancer (EHBTC. The aim of this study was to analyze the clinical features and outcomes between patients undergoing adjuvant concurrent chemoradiation therapy (CCRT alone and those undergoing CCRT followed by adjuvant chemotherapy after curative resection. Methods We included 120 patients with EHBTC who underwent radical resection and then received adjuvant CCRT with or without further adjuvant chemotherapy between 2000 and 2006 at Seoul National University Hospital. Results Out of 120 patients, 30 received CCRT alone, and 90 received CCRT followed by adjuvant chemotherapy. Baseline characteristics were comparable between the two groups. Three-year disease-free survival (DFS rates for CCRT alone and CCRT followed by adjuvant chemotherapy were 26.6% and 45.2% (p = 0.04, respectively, and 3-year overall survival (OS rates were 30.8% and 62.6% (p Conclusion Adjuvant CCRT followed by adjuvant chemotherapy prolonged DFS and OS, compared with CCRT alone in patients with curatively resected EHBTC. Adjuvant chemotherapy deserves to consider after adjuvant CCRT. In the future, a randomized prospective study will be needed, with the objective of investigating the role of adjuvant chemotherapy.

    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

    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.

    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.

    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.

    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.

    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

    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.

    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.

    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.

    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

    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.

    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.

    Biliary anatomy and its common and uncommon variations are of considerable clinical significance when performing living donor transplantation, radiological interventions in hepatobiliary system, laparoscopic cholecystectomy, and liver resection (hepatectomy, segmentectomy). Because of increasing trend found in the number of liver transplant surgeries being performed, magnetic resonance cholangiopancreatography (MRCP) has become the modality of choice for noninvasive evaluation of abnormalities of the biliary tract. The purpose of this study is to describe the anatomic variations of the intrahepatic and extrahepatic biliary tree. PMID:27081220

    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.

    One of the best known side effects of using opium is spasm of the sphincter of Oddi, which may increase the diameter of the extrahepatic bile ducts. Ultrasound is the first imaging modality used for evaluating the biliary system because it is commonly available and noninvasive. The principal objective of this study was to measure the common bile duct (CBD) diameter via ultrasonography in opium addicts and to evaluate the relation between the CBD diameter and the period of addiction. This research was an analytical-cross sectional study that was done on 110 opium addicts that were admitted to a drug treatment center. The diameter of the CBD in these cases was measured by ultrasonography and the results were analyzed with other factors like age, the period of addiction and the laboratory findings. According to the findings, there is a significant increase in the range of the CBD diameter in comparison with normal bile ducts. Also, the mean diameter of the CBD in the different age groups showed a significant difference (p < 0.0001) and there was a significant relation between the CBD diameter and the period of addiction (p < 0.001, r = 0.74); so, with the increased length of the addiction period, the mean CBD diameter increases. Opium addiction is one of the factors that causes extrahepatic bile duct dilatation, so in these cases, if no obstructing lesion was found on ultrasound examination and the serum bilirobine and alkaline phosphatase levels are normal, then further evaluation is not needed.

    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.

    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

    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.

    No study on mutations in the K-ras oncogene and cancer of the exocrine pancreas or cancer of the biliary system has analyzed the reliability of clinical and epidemiological information. Agreement between patient and surrogate on factors potentially related to both tumours was evaluated within a multicentre prospective study. Interviews were personally administered to both patient and surrogate (N = 110 pairs). Agreement was examined via the simple kappa index (k), the weighted kappa index (kw), the percentage of simple agreement, and the percentages of positive and negative agreement. Agreement for medical history was excellent (k between 0.89 and 0.76), as it was for tobacco consumption (k = 0.98). Agreement was moderate for coffee consumption (k = 0.68), frequencies of food groups (kw from 0.66 to 0.38), and consumption of alcoholic drinks (k from 0.66 to 0.32). Surrogates indicated a higher consumption of alcohol than patients. Surrogates can be an alternative source of information when patients cannot be interviewed, but information on alcohol consumption should be treated with caution.

    Full Text Available To evaluate the long-term results of surgery for choledohal cyst in adulthood, a series of 13 patients over the age of 16 operated on for choledochal cyst during a period of six years and followed-up for a minimum of 3 years was analyzed. Patients with type I and IVa cysts underwent extrahepatic cyst resection and Roux-en-Y hepatico-jejunostomy. Choledochoceles (type III were managed endoscopically. No operative mortality or morbidity occurred. Type I and III cysts showed almost ideal follow-up with no sign of stricture on HIDA scan. One type IVa cyst patients developed recurrent cholangitis due to anastomotic stricture, managed percutaneously. Whenever possible, complete cyst resection and Roux-en-Y reconstruction is the treatment of choice for all extrahepatic biliary cysts. Intra- and extrahepatic dilatations are adequately treated by extrahepatic resection and careful endoscopic or radiologic surveillance. Small choledochoceles can be safely managed by endoscopic sphincterotomy.

    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.

    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

    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.

    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.

    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.

    Cholangiocarcinoma (CCA) is a rare cancer of the biliary epithelium comprising only about 3% of all gastrointestinal malignancies. It is a highly aggressive malignancy and confers a dismal prognosis with majority of patients presenting with metastatic disease. Metastatic CCA to the colon is extremely rare with only few cases reported in the literature. We present a 61-year-old patient with incidental synchronous metastatic colonic adenocarcinoma from extra-hepatic CCA. Laboratory data revealed significant indirect hyperbilirubinemia and transaminitis. Imaging study showed intrahepatic bile ducts prominence without mass lesions. Incidentally, there was diffuse colonic thickening without mass lesions or obstruction. Endoscopic retrograde cholangiopancreatography (ERCP) showed a common bile duct stricture. Brushings were consistent with CCA. Screening colonoscopy identified nodularity and biopsy and immunostaining were consistent with CCA metastasis to colon. The patient elected for palliative and comfort care. Metastatic CCA to the colon is a rare pattern of distant spread that may pose a diagnostic challenge. Some salient characteristics may assist in the differentiation of primary colon cancer and metastatic colon cancer from CCA. Little remains known about the pathogenic behavior of metastatic secondary colorectal cancer. And more so, the management approach to such metastatic cancer still remains to be defined. Screening colonoscopy in patients presenting with resectable CCA may alter management. Furthermore, whether patients with history of resected CCA may benefit from a more frequent screening colonoscopy remains to be validated.

    The purpose of the study was to evaluate the respiratory variation of the extrahepatic bile duct in morphology including shape, length and duct diameter on the breath-hold magnetic resonance cholangiopancreatography (MRCP) obtained during deep inspiration and deep expiration in patients with or without biliary diseases. This study included 102 patients with or without biliary diseases. Breath-hold MRCP was obtained twice during the end-inspiration and the end-expiration. MRCP images were evaluated for the length, maximal diameter and "bowing" of the extrahepatic bile duct. In the normal group, the mean maximal diameter of the extrahepatic bile duct was significantly larger on the end-inspiratory MRCP (8.0 ± 2.0 mm) than on the end-expiratory MRCP (7.3 ± 1.8 mm) (P<.0001), while it was not significantly different in the dilated group. In the normal group, 25 (39%) of 65 patients had an increase in the mean maximal diameter of more than 1 mm at the end-inspiration, whereas 4 (11%) of 37 patients in the dilated group had it. The bowing of the extrahepatic bile duct on the end-inspiratory MRCP was observed in 60 (92%) of 65 normal patients, while it was seen in 22 (60%) of 37 patients with biliary dilatation (P<.0001). Deep inspiratory and expiratory MRCP demonstrated the respiratory variations of the extrahepatic bile duct in the shape (bowing), length and maximal duct diameter in patients with nondilated bile ducts. Awareness of this normal phenomenon will be important for the correct interpretation of MRCP in patients with or without biliary diseases. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available Over-the-Scope Clip system, also called “Bear Claw,” is a novel endoscopic modality used for closure of gastrointestinal defect with high efficacy and safety. We present a patient with history of eosinophilic gastroenteritis and multiple abdominal surgeries including Billroth II gastrectomy complicated by a large chronic duodenocutaneous fistula from a Billroth II afferent limb to the abdominal wall. Bear Claw clip was used for closure of this fistula. The patient developed acute cholangitis one day after placement of the Bear Claw clip. Acute cholangitis due to papillary obstruction is a potential complication of Bear Claw placement at the dome of the duodenal stump (afferent limb in patient with Billroth II surgery due to its close proximity to the major papilla.

    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.

    PurposeThe clinical efficacy of intraductal radiofrequency ablation (RFA) with Habib™ EndoHPB catheter, a newly developed intervention for malignant extrahepatic biliary obstruction, remains uncertain. The aim of this study was to investigate the clinical efficacy of intraductal RFA.MethodsData from 71 patients with extrahepatic distal cholangiocarcinoma were retrospectively analyzed. The study patients were divided into RFA and control groups. The RFA group had undergone percutaneous transhepatic intraductal RFA with a Habib™ EndoHPB catheter, followed by placement of covered or uncovered biliary self-expandable metallic stents (SEMs) whereas the control group had undergone percutaneous transhepatic covered or uncovered SEMs placement. Procedure-related complications, stent patency, patient survival, and postoperative serum bilirubin concentrations were compared between the two groups. The Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaire was administered to evaluate functional status, improvement in clinical manifestations, and quality of life.ResultsThe RFA group had a longer median stent patency than the control group (p = 0.001 for uncovered SEMs placement). Higher functional well-being, hepatobiliary-specific cancer subscale, Trial Outcome Index, and total FACT-Hep scores were observed during post-procedure follow-up in the RFA group. However, median survival did not differ significantly between the two groups (p > 0.05).ConclusionsProlongation of stent patency and better functional status and quality of life, which are all important clinical endpoints, were observed in patients treated with intraductal RFA. Prospective randomized controlled clinical trials are necessary to further investigate the clinical efficacy and long-term benefits of intraductal RFA.

    Orłowska, Ewa; Czubkowski, Piotr; Socha, Piotr

    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.

    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.

    Portal biliopathy (PB) refers to the biliary abnormalities of the biliary ducts observed in patients with extrahepatic portal hypertension. Although majority of patients are asymptomatic, approximately 20% of these patients present with biliary symptoms (pain, pruritus, jaundice, cholangitis). The pathogenesis of PB is uncertain but compression by dilated veins into or around common bile duct may play the main role. CT-scan, MR cholangiopancreatography with MR portography should be the initial investigations in the evaluation of PB. Treatment is limited to symptomatic cases and is dictated by clinical manifestations and complications of the disease. Treatment of PB could be done by endoscopy (sphincterotomy, stone extraction or biliary stenting of the common bile duct) or surgery (definitive decompression by porto-systemic shunt followed by bilioenteric anastomosis, if necessary). This review describes pathogenesis, clinical features, investigation and management of portal biliopathy. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Traumatic neuromas (TN) of the biliary tree causing strictures have only occasionally been described after liver transplantation. Herein, we have reported 15 cases of TN that were detected between 1 and 17 months after transplantation (median: 4 months) during surgery for obstructive jaundice (12 cases), after alterations of liver function tests (two cases), or incidentally discovered after retransplantation (n = 1) we resected the lesion and the biliary anastomosis. Pathological examination and immunostaining for S-100 protein were performed to study the nerve fascicles. After a median follow-up time of 64 months (range = 0-127), 10 patients are alive without any complication related to the previous biliary TN. We propose the following classification: type I: TN originating from and located in the main biliary tract wall, and type II: TN arising from the surrounding tissues next to the main biliary tract. We conclude that TN are not uncommon after liver transplantation and that they are sometimes symptomatic, causing a biliary stricture that requires surgical treatment. We propose a classification to help patient selection for surgery. In our opinion, resection of the TN is the operation of choice, together with resection of the involved biliary tract in type I TN.

    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.

    Full Text Available Portal biliopathy (PB can involve the whole biliary system and this article mainly introduces extrahepatic PB that involves the extrahepatic bile duct, the cystic duct, and the gallbladder. This disease is relatively rare in clinical practice, and most doctors do not have enough knowledge of this disease. Since this disease involves the rich vascular systems and the fine biliary system, its therapeutic regimens should be selected carefully; improper therapeutic regimens may easily cause massive hemorrhage and bile duct injury, make patients' conditions worse, and even threaten their lives. At present, there is still no standard flow chart for the treatment of PB around the world. Endoscopic therapy and surgical interventional treatment are commonly used minimally invasive therapies in clinical practice. This article reviews the pathogenesis of PB and minimally invasive therapies currently used in clinical practice, in order to provide a basis for scientific diagnosis and treatment of this disease.

    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.

    To describe the technical feasibility and usefulness of extrahepatic biliary stone removal by balloon sphincteroplasty and occlusion balloon pushing. Fifteen patients with extrahepatic bile duct stones were included in this study. Endoscopic stone removal was not successful in 13 patients, and two patients refused the procedure due to endoscopy phobia. At first, all patients underwent percutaneous transhepatic biliary drainage (PTBD). A few days later, through the PTBD route, balloon assisted dilatation for common bile duct (CBD) sphincter was performed, and then the stones were pushed into the duodenum using an 11.5 mm occlusion balloon. Success rate, reason for failure, and complications associated with the procedure were evaluated. Eight patients had one stone, five patients had two stones, and two patients had more than five stones. The procedure was successful in 13 patients (13/15). In 12 of the patients, all stones were removed in the first trial. In one patients, residual stones were discovered on follow-up cholangiography, and were subsequently removed in the second trial. Technical failure occurred in two patients. Both of these patients had severely dilated CBD and multiple stones with various sizes. Ten patients complained of pain in the right upper quadrant and epigastrium of the abdomen immediately following the procedure, but there were no significant procedure-related complications such as bleeding or pancreatitis. Percutaneous extrahepatic biliary stone removal by balloon sphincteroplasty and subsequent stone pushing with occlusion balloon is an effective, safe, and technically feasible procedure which can be used as an alternative method in patients when endoscopic extrahepatic biliary stone removal was not successful.

    Full Text Available Abstract Introduction The variations in the morphological characteristics of the extra-hepatic biliary system are interesting. Case presentation During the dissection of cadavers to study the morphological characteristics of the extra-hepatic biliary system, a 46-year-old male cadaver was found to have drainage of the common hepatic duct drains directly into the gall bladder neck. The right and left hepatic ducts were not seen extra-hepatically. Further drainage of the bile away from the gallbladder and into the duodenum was provided by the cystic duct. Formation of the common bile duct by the union of the common hepatic duct and cystic duct was absent. Further more the right hepatic artery was found to be communicating with the left hepatic artery by a "bridging artery" after giving rise to the cystic artery. An accessory hepatic artery originated from the "bridging artery" forming a "cruciate" hepatic arterial anastomosis. Conclusion Combination of a Hepaticocystic duct and an aberrant variation in the extra-hepatic arterial system is extremely rare.

    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.

    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

    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.

    Full Text Available OBJECTIVE: To verify whether the ileal exclusion interferes with liver and kidney functional changes secondary to extrahepatic cholestasis.METHODS: We studied 24 rats, divided into three groups with eight individuals each: Group 1 (control, Group 2 (ligation of the hepatic duct combined with internal biliary drainage, and Group 3 (bile duct ligation combined with internal biliary drainage and exclusion of the terminal ileum. Animals in Group 1 (control underwent sham laparotomy. The animals of groups 2 and 3 underwent ligation and section of the hepatic duct and were kept in cholestasis for four weeks. Next, they underwent an internal biliary bypass. In Group 3, besides the biliary-enteric bypass, we associated the exclusion of the last ten centimeters of the terminal ileum and carried out an ileocolic anastomosis. After four weeks of monitoring, blood was collected from all animals of the three groups for liver and kidney biochemical evaluation (albumin, ALT, AST, direct and indirect bilirubin, alkaline phosphatase, cGT, creatinine and urea.RESULTS: there were increased values of ALT, AST, direct bilirubin, cGT, creatinine and urea in rats from Group 3 (p < 0.05.CONCLUSION: ileal exclusion worsened liver and kidney functions in the murine model of extrahepatic cholestasis, being disadvantageous as therapeutic procedure for cholestatic disorders.

    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.

    To characterize extrahepatic pseudoaneurysm regarding incidence and etiology and determine the effectiveness of endovascular management. A retrospective audit of 1,857 liver transplants in two institutions was performed (1996-2009). Recipients' demographics, clinical presentation, transplant type, biliary anastomosis, and presence of biliary endoprostheses were noted. Pseudoaneurysms were classified into iatrogenic (associated with biliary endoprosthesis or angioplasty) or spontaneous extrahepatic pseudoaneurysms. Spontaneous and iatrogenic pseudoaneurysms were compared for time from transplant, presenting symptoms, location in the arterial anatomy, and 3-month graft survival. Arterial patency and 6-month graft survival were calculated. Twenty pseudoaneurysms were found (1.1 %, 20/1,857): 9 (0.5 % of transplants, 9/1,857) were spontaneous and 11 (0.6 % of transplants, 11/1,857) were 'iatrogenic' (due to minimally invasive procedures: 4 angioplasty and 7 biliary endoprostheses). Sixty percent (12/20) underwent endovascular management (4 coil embolization and 8 stent-grafts). Technical success was 83 % (10/12) with a mean arterial patency of 70 % (follow-up mean, 4.9; range, 0-18 months). The 1-, 3-, and 6-month graft survival was 70, 40, and 35 %, respectively. Due to minimally invasive procedures, posttransplant extrahepatic pseudoaneurysms are no longer an exclusive complication of the transplant surgery itself. Endovascular management is effective to stabilize patients but has not improved historic postsurgical graft survival.

    Few investigations of biliary tract (gallbladder, extrahepatic bile duct, ampulla of Vater) cancers have been conducted because of the relative rarity of these malignancies. The objective of this analysis was to compare the demographic, pathological, and clinical features of biliary tract cancers among men and women. Biliary tract cancers among 11,261 men and 15,722 women were identified through 33 US population-based registries during the period 1997-2002. These registries were estimated to represent 61% of the US population. Age-adjusted incidence rates (AAIR) were calculated per 100,000 population using counts derived from the 2000 US census. The AAIR for gallbladder cancer among men (0.82 per 100,000) was significantly lower than the AAIR among women (1.45 per 100,000). By contrast, rates for extrahepatic bile duct and ampullary cancers were significantly higher among men (0.93 per 100,000 and 0.70 per 100,000, respectively) than among women (0.61 per 100,000 and 0.45 per 100,000, respectively). White men and women had significantly lower AAIRs for gallbladder cancer compared with other racial-ethnic groups, with the highest rates among Hispanics, American Indian-Alaska Natives, and Asian-Pacific Islanders. Asian-Pacific Islanders and Hispanics of both sexes had the highest AAIRs for extrahepatic bile duct and ampullary cancers. Ampullary tumors were more likely to be diagnosed at a localized or regional stage than were cancers of the gallbladder and extrahepatic bile duct. Asian-Pacific Islander men and women tended to have more unstaged cancers than other groups. This population-based study suggests distinct etiologies of anatomic subsites of biliary tract cancer and caution against analytic investigations of all biliary tract cancers combined.

    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.

    Full Text Available BACKGROUND: Several studies carried out to examine the growth of children with extra-hepatic portal vein obstruction and portal hypertension have reported a variety of findings. AIM: To assess anthropometric indices in children with portal hypertension due to extra-hepatic portal vein obstruction and who were treated by endoscopic variceal sclerotherapy. METHODS: Anthropometric data were obtained retrospectively from the medical records of 24 patients who had been followed for 3.8 ± 2.5 years at the Pediatric Gastroenterology Outpatient Clinic of the University Hospital, Campinas, SP, Brazil. The mean Z scores of weight for age, height for age and body mass index at diagnosis and at the last consultation were compared to reference data of the National Center for Health Statistics. The two recordings were compared to assess the long-term effect of the condition. RESULTS: The mean Z scores at diagnosis and at the last follow-up visit were all within normal ranges when compared to the reference population, with the following respective values: weight for age, 0.042 ± 1.09 and 0.132 ± 1.29; height for age, 0.200 ± 1.04 and 0.466 ± 1.24, and body mass index, -0.223 ± 0.98 and -0.198 ± 0.98. In addition, there were no significant differences between the Z score values obtained in the two recordings. CONCLUSION: Portal hypertension due to extra-hepatic portal vein obstruction was not associated with growth impairment in the group of children studied.RACIONAL: Dados referentes às repercussões da obstrução extra-hepática da veia porta sobre o crescimento de crianças são escassos.

    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.

    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.

    To assess the frequency and clinical impact of associated extrahepatic autoimmune diseases (EAD) on autoimmune liver diseases (ALD). We investigated 608 patients with ALD (327 autoimmune hepatitis - AIH and 281 primary biliary cirrhosis - PBC) for concomitant EAD. In both AIH and PBC, we observed a high prevalence of EAD (29.9 and 42.3%, respectively); both diseases showed a significant association with autoimmune thyroid disease, followed by autoimmune skin disease, celiac disease, and vasculitis in AIH patients and sicca syndrome, CREST syndrome, and celiac disease in PBC patients. At diagnosis, AIH patients with concurrent EAD were more often asymptomatic than patients with isolated AIH (Pautoimmune thyroid disease. In the light of our results, all patients with an EAD should be assessed for the concomitant presence of an asymptomatic ALD.

    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.

We used the World Health Organization classification criteria for EHBC.Materials and methods: This was a retrospective study using 88 tissue samples, including 45 samples from non-neoplastic biliary tissue (NNB and 43 samples of extrahepatic cholangiocarcinoma (EHBC. A tissue microarray including NNB and EHBC was constructed and analyzed by immunohistochemistry (IHC and dual in situ hybridization for Her-2/neu protein expression and amplification, respectively. The Her-2/neu expression was scored following the guidelines used for the ToGA study.Results: All NNB samples and all but one EHBC samples showed no expression of Her-2/neu by IHC. The one EHBC case immunohistochemically positive for Her-2/neu had an IHC score of 3+. Her-2/neu gene amplification was present in two EHBC samples only and included the case found to be positive by IHC.Conclusion: Our findings are similar to those reported in the literature. Although Her-2/neu overexpression has been documented in many types of cancer, Her-2/neu protein overexpression tends to have no role in the development and/or progression of EHBC.

    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.

    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.

    Magnetic resonance cholangiopancreatography (MRCP) could aid in the diagnosis of biliary atresia, a hepatic pathology with thin, irregular or interrupted biliary ducts. There is little published evidence of MRCP appearances in normal neonates and young infants. To assess the use of MR cholangiopancreatography in visualizing the biliary tree in neonates and infants younger than 3 months with no hepatobiliary disorder, and to assess this visibility in relationship to the child's age, weight, and sedation and fasting states. Between December 2008 and October 2010 our department performed MRI of the brain, orbits and face on 16 full-term neonates and infants. Each child was younger than 3 months (90 days) and without any hepatobiliary disorders. The children were scanned with a respiratory-gated 0.54 x 0.51 x 0.4-mm{sup 3} 3-D MRCP sequence. We used a reading grid to assess subjectively the visibility of the extrahepatic bile ducts along with extrahepatic bile duct confluence. The visibility of the extrahepatic bile duct confluence was assessed against age, weight, and sedation and fasting states. The extrahepatic bile duct confluence was seen in 10 children out of 16 (62.5%). In the neonate sub-group (corrected age younger than 30 days), the MRCP was technically workable and the extrahepatic bile duct confluence was seen in four cases out of eight (50%). This visualization was up to 75% in the subgroup older than 30 days. However, statistically there was no significant difference in visibility of the extrahepatic bile duct confluence in relationship to age, weight or MRCP performance conditions (feeding, fasting or sedation). The complete normal biliary system (extrahepatic bile duct confluence included) is not consistently visualized in infants younger than 3 months old on non-enhanced MRCP. Thus the use of MRCP to exclude a diagnosis of biliary atresia is compromised at optimal time of surgery. (orig.)

    Full Text Available Abstract Background Metastatic hernia sac tumor from biliary malignancy is extremely rare with only one such case previously reported. We herein report an additional case of extrahepatic cholangiocarcinoma presenting as a hernia sac tumor. Case presentation A 78-year-old man presented with an irreducible right inguinal hernia associated with a firm tumor, 2.0 cm in diameter. A computed tomography scan demonstrated a soft tissue density mass with heterogeneous enhancement within the right inguinal canal. The patient underwent a hernia repair and the hernia sac tumor was resected. Histological examination of the tumor revealed a metastatic adenocarcinoma suggesting the tumor was of pancreato-biliary origin. Further investigation using imaging studies disclosed a primary tumor in the upper bile duct. The patient died of the disease nine months after the resection. Conclusion Hernia sac tumors should be considered when an irreducible, growing mass appears within an inguinal hernia. Computed tomography may be useful for the early detection of hernia sac tumors from undiagnosed intra-abdominal malignancies.

    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.

    Full Text Available Biliary atresia is an inflammatory fibrosing process, which invades both extrahepatic and intrahepatic bile ducts. 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.

    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.

    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.

    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.

    Recurrent hepatocellular carcinoma (HCC) in the extrahepatic bile duct is rare with most cases diagnosed after manifesting sudden obstructive jaundice. Here, we report an extremely rare case of recurrent HCC in the common bile duct due to hematogenous metastasis. A 66-year-old man underwent an extended left hepatectomy for HCC in the medial segment of the liver. Fifty months later, he presented with sudden obstructive jaundice. Endoscopic retrograde cholangiography showed a space-occupying lesion in the common bile duct, which was suspected as cholangiocarcinoma. Therefore, he underwent extrahepatic bile duct resection and choledochojejunostomy with lymph node dissection. Macroscopically, a polypoid tumor and several nodular tumors were found in the common bile duct, which was obstructed by a tumor thrombus. Histopathologically, the tumors were diagnosed as metastases from the HCC resected 50 months before. Several distinct, nodular tumors were observed in the subepithelium of the common bile duct and had invaded some blood vessels. These findings support the conclusion that the HCC metastasized hematogenously to the extrahepatic bile duct. Recurrent HCC in the extrahepatic bile duct due to hematogenous metastasis is rare, and it is difficult to diagnose. Further similar cases should be accumulated for clarifying the pathological mechanism.

    A 73-year-old woman was admitted because of obstructive jaundice. Computed tomography revealed a stricture in the lower bile duct with enhanced bile duct wall. Endoscopic retrograde cholangiopancreatography (ERCP) revealed a tapering stenosis at the lower bile duct. Transpapillary histological biopsy using biopsy forceps through ERCP was performed; the diagnosis of signet ring cell carcinoma (SRCC) of the bile duct was established. Regional lymph node enlargement and distant metastases were not detected on diagnostic imaging. Pancreaticoduodenectomy with pylorus preservation was performed. Histological examination of the resected specimen confirmed SRCC of the extrahepatic bile duct coexisting with adenocarcinoma (ADC) of the extrahepatic bile duct with negative resection margins. However, tumor cells directly invaded the pancreatic parenchyma and the muscle layer of the duodenum, prompting us to administer adjuvant chemotherapy to the patient, with no sign of tumor recurrence at 1-year follow-up. Almost all tumors originating from the extrahepatic bile duct are ADC and other histological variants are rare. Of these, SRCC is extremely rare and only four cases have been reported. Furthermore, to the best of our knowledge, this is the first case report regarding the preoperative diagnosis of SRCC of the bile duct. Current reports indicate that younger age and Asian ethnicity are the clinical features of SRCC of the extrahepatic bile duct. Immunohistochemical staining of CK7, CK20 and MUC2 may be useful for predicting prognosis. Chemotherapy has not resulted in increased survival rates and only surgical resection currently serves as a curative treatment.

    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.

    The authors consider the tactics of the treatment of mechanical jaundice in 9 patients suffering from an extrahepatic form of portal hypertension. The analysis of the results of the treatment proved that in case of pronounced bilirubinemia with colangitis manifestations and hepatic insufficiency it is indicated to use external controlled drainage of the thoracic lymphatic duct and transhepatic external drainage of the intrahepatic duct. The applied tactics allows to avoid carrying out emergent surgical interventions on extrahepatic bile passages, which is extremely dangerous, and to perform such operations when necessary only, under more favourable conditions after an adequate preparation of patients.

    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.

    2016-01-01

    Biliary Atresia is a progressive, fibro-obliterative disorder of the intra and extrahepatic bile ducts in infancy. The majority of affected children will eventually develop end-stage liver disease and require liver transplantation. Indications for liver transplant in biliary atresia include failed Kasai portoenterostomy, significant and recalcitrant malnutrition, recurrent cholangitis, and the progressive manifestations of portal hypertension. Extra-hepatic complications of this disease, such as hepatopulmonary syndrome and portopulmonary hypertension, are also indications for liver transplantation. Optimal pre-transplant management of these potentially life threatening complications and maximizing nutrition and growth require the expertise of a multi-disciplinary team with experience caring for biliary atresia. The timing of transplant for biliary atresia requires careful consideration of the potential risk of transplant versus the survival benefit at any given stage of disease. Children with biliary atresia often experience long wait times for transplant unless exception points are granted to reflect severity of disease. Family preparedness for this arduous process is therefore critical. PMID:27650268

    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.

    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.

    44 clinical cases, histologically diagnosed as suffering from extrahepatic bile duct neoplasia, admitted at the "Hospital Foral de Navarra" during the years 1976 to 1985 and at the "Hospital Clinico Universitario de Salamanca" during the period from 1981 to 1987, were analysed. Our results showed a higher incidence in the female sex. The most important antecedent was biliary stone lithiasis (45.45%). Jaundice and abdominal pain were the most frequent symptoms and liver enlargement accompanied by jaundice were the most frequent clinical signs on physical examination. The data obtained did not show specificity at the diagnosis. The ERCP showed a high rate of diagnosis (71.43%) followed by CT scanning (70%) and percutaneous transhepatic cholangiography (52.63%). The types of surgery most frequently performed were cholecystectomy and choledochoduodenostomy, and the diagnosis of well-differentiated carcinoma was found in 63.64% of the cases. Any therapy performed (surgery, radiotherapy and/or chemotherapy) improved the survival rate.

    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

    Full Text Available Abstract Background Biliary atresia (BA is the most severe hepatic disorder in newborns and its etiopathogenesis remains unknown. Viral involvement has been proposed, including the human cytomegalovirus (HCMV. The aims of the study were to use the polymerase chain reaction (PCR to screen the liver tissue of infants with extrahepatic cholestasis for HCMV and to correlate the results with serological antibodies against HCMV and histological findings. Methods A retrospective study in a tertiary care setting included 35 patients (31 BA, 1 BA associated with a choledochal cyst, 2 congenital stenosis of the distal common bile duct and 1 hepatic cyst. HCMV serology was determined by ELISA. Liver and porta hepatis were examined histologically. Liver samples from infants and a control group were screened for HCMV DNA. Results Twelve patients had HCMV negative serology, 9 were positive for IgG antibodies and 14 were positive for IgG and IgM. Nine liver and seven porta hepatis samples were positive for HCMV DNA but none of the control group were positive (general frequency of positivity was 34.3% – 12/35. There was no correlation between HCMV positivity by PCR and the histological findings. The accuracy of serology for detecting HCMV antibodies was low. Conclusion These results indicate an elevated frequency of HCMV in pediatric patients with extrahepatic neonatal cholestasis. They also show the low accuracy of serological tests for detecting active HCMV infection and the lack of correlation between HCMV positivity by PCR and the histopathological changes.

    The hagfish liver was histochemically examined with special attention to biliary structures around the portal veins. Hepatocytes were organized into tubular structures surrounded by sinusoids. Biliary ductule structures, which resemble the ductal plates transiently appearing in mammalian liver development, were observed around the portal veins, but they did not appear around central veins. Thus, the hagfish liver demonstrates the same basic structure as the mammalian liver; that is, a vascular system from portal to central veins via sinusoids, and portal triad structures consisting of portal veins, hepatic arteries, and intrahepatic bile ducts. The epithelial cells of the ductal platelike structures strongly expressed cytokeratin, had some lectin-binding sites, and were delineated by the basal lamina, which was reactive for periodic acid-Schiff (PAS) staining and Iectin histochemistry. The lumina of the ductal plate-like structures were comparatively small and heterogeneous in diameter around the portal veins, suggesting that the biliary structures may not be efficient for bile secretion. The epithelial cells of the gall bladder had a simple columnar shape and were a PAS-positive cytoplasm. Those of bile ducts near the hilus, including extrahepatic and hepatic ducts, were simple columnar or cuboidal cells, and had large lumina. The cytoplasm in these cells was PAS-positive. These phenotypes with the expression of lectin-binding sites were clearly different from those of the ductal plate-like structures in the liver proper, suggesting that the extrahepatic and intrahepatic biliary structures may have different developmental origins.

  20. Primary biliary cirrhosis: Report

    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.

    Extrahepatic portal venous obstruction can be associated with bile duct abnormalities, the entity being called portal biliopathy. Three cases are reported of extrahepatic bile duct strictures in patients with portal biliopathy who developed haemobilia during endotherapy. Although endoscopic therapy with stent placement can be successful in patients with portal biliopathy and could also lead to permanent stricture resolution, procedure-related haemobilia is not as uncommon as previously held. Shunt surgery could be a better option in fit patients, since it could provide definitive treatment in a young patient with an otherwise normal life expectancy.

    INTRODUCTION: Biliary atresia is the leading cause of liver transplantation in children. It affects 1:15,000 in Denmark. With a national birth rate of 60,000, four children are born every year with biliary atresia. Early correction of biliary obstruction is essential to prevent fatal biliary...... cirrhosis. The Danish Health and Medicines Authority (DHMA) demands diagnostic evaluation of children with elevated level of serum bilirubin after two weeks of age. Biliary atresia has to be excluded if conjugated bilirubin level is above than 20 μmol/l, and/or more than 20% of total bilirubin....... This percentage value has caused diagnostic trouble over the years. The objective of the present study was to investigate the possibility of changing the recommendations. METHODS: This was a retrospective analysis of the medical records of children operated for biliary atresia in the 1993-2012 period. RESULTS...

    Sepsis of the biliary tract is a severe disease, due to its course and its significant association with relevant diseases, either benign or malignant, of the biliary tract, pancreas, hepatic hilus. In many cases it remains difficult to set the limit between medical therapy, percutaneous or endoscopic therapy and surgical treatment. Through a thorough review of the last 20 years' literature, we have studied this topic and classified cholangitis according to its etiology: Iithiasis, benign stenosis or Klatskin tumor as malignant diseases. The sequential approach, endoscopy-surgery, seems to provide the best results in lithiasic cholangitis. In patients with benign stenosis of the biliary tract, a percutaneous drainage is indicated as a first choice, meanwhile surgery is limited to unsuccessful bilioplasty and to segmental extrahepatic localization of sclerosing cholangitis. On the contrary, in Klatskin tumours preoperative percutaneous drainages are useful to obtain an accurate map, which is indispensable to perform an aggressive radical hepatic resection.

    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.

    The aim of this study is to determine the feasibility and effectiveness of performing an ultrasound-guided percutaneous cholecysto-cholangiogram (PCC) for excluding biliary atresia as the cause of neonatal jaundice. Between Oct. 2003 and Feb. 2005, six ultrasound-guided PCC procedures were performed to five jaundiced infants (4 females and 1 male; mean age: 60 days old) for whom possibility of biliary atresia could not be ruled out by the DISIDA scan as the cause of their neonatal jaundice. Gallbladder puncture was performed under ultrasound guidance with a 23-gauge needle. Contrast material injection during fluoroscopic examination was performed after dilatation of the gallbladder lumen with normal saline under ultrasound guidance. The criteria used for excluding biliary atresia were complete visualization of the extrahepatic biliary trees and/or contrast excretion into the duodenum. The complications and final diagnosis was assessed according to the clinical and laboratory findings. The procedures were successful in all the patients without any complication. Biliary atresia could be ruled out in all the patients. The final diagnosis was neonatal cytomegalovirus hepatitis in two patients, total parenteral nutrition-associated cholestasis in two patients, and combined cytomegalovirus hepatitis and total parenteral nutrition-associated cholestasis in one patient. Ultrasound-guided PCC is a feasible and effective method for the early definitive exclusion of biliary atresia as the cause of neonatal jaundice. By the technique of injecting normal saline before contrast injection, PCC can be done even in a totally collapsed or very small gallbladder.

    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.

  7. 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.

    The biliary tract cancer or cholangiocarcinoma (CCA) represents the sixth leading cause of gastrointestinal tumors in the Western world, and mortality varies across the world, with regions such as Chile, Thailand, Japan, and northeastern India presenting the highest rates. CCA may develop in the bile duct, gallbladder, or ampulla of Vater; and risk factors include obesity, parity, genetic background, geographical and environmental factors. Inflammation induced by bacterial infections might play a role in the pathogenesis of CCA. In this work, we investigated whether there is an association between extrahepatic cholangiocarcinoma (ECCA) and infection with S. typhi, H. hepaticus, or H. bilis in a Mexican population. A total of 194 patients were included and divided into 91 patients with benign biliary pathology (controls) and 103 with ECCA (cases). Tumor samples were taken during endoscopic retrograde cholangiopancreatography by biliary brushing, followed by DNA extraction and PCR testing for infections. We found that 44/103 cases were positive for H. bilis, compared with 19/91 controls (p = 0.002; OR 2.83, 95% CI 1.49-5.32), and when analyzed by sub-site, H. bilis infection was significantly more associated with cancer in the common bile duct (p = 0.0005; OR 3.56, 95% CI 1.77-7.17). In contrast, H. hepaticus infection was not different between cases (17/103) and controls (13/91) (p = 0.82; OR 1.19, 95% CI 0.54-2.60). None of the samples were positive for S. typhi infection. In conclusion, infection with H. bilis but neither H. Hepaticus nor S. typhi was significantly associated with ECCA, particularly with tumors located in the common bile duct. © 2015 John Wiley & Sons Ltd.

    2017-05-01

    Full Text Available Biliary-pleural fistula (BPF, an abnormal communication between the biliary tract and pleural space, is a rare but potentially life-threatening complication following percutaneous biliary intervention. 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.

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.

    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.

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

    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.

    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

Both disease processes are characterized by a destruction of intrahepatic and/or extrahepatic biliary ducts. The etiology is not entirely clear; however, there is an underlying autoimmune component contributing to both disease processes. Although PBC and PSC are often diagnosed and managed in the outpatient setting, in some instances, a patient may have jaundice, fatigue, and pruritus requiring evaluation and determination of the cholestatic cause. Patients with PSC should be monitored for evidence of cholangiocarcinoma, colon cancer, and gallbladder polyps as they are at an increased risk of malignant neoplasms. Liver transplant has the potential for improving quality of life, although disease recurrence is a risk. ©2016 American Association of Critical-Care Nurses.

    Biliary cystadenoma is a rare cystic hepatic neoplasm. We herein present a 44 year-old female patient with biliary cystadenoma focusing on difficulties in diagnosis because of lack of specific findings with imaging, and the need for surgery. As biliary cystadenomas have high recurrence risks and malignant transformation potential, careful follow-up should not be underestimated. Proper surgical resection of the lesion may be considered the most suitable diagnostic and therapeutic procedure, an...

    Full Text Available Extrahepatic hepatic ductal injuries (EHDIs due to blunt abdominal trauma are rare. Given the rarity of these injuries and the insidious onset of symptoms, EHDI are commonly missed during the initial trauma evaluation, making their diagnosis difficult and frequently delayed. Diagnostic modalities useful in the setting of EHDI include computed tomography (CT, abdominal ultrasonography (AUS, nuclear imaging (HIDA scan, and cholangiography. Traditional options in management of EHDI include primary ductal repair with or without a T-tube, biliary-enteric anastomosis, ductal ligation, stenting, and drainage. Simple drainage and biliary decompression is often the most appropriate treatment in unstable patients. More recently, endoscopic retrograde cholangiopancreatography (ERCP allowed for diagnosis and potential treatment of these injuries via stenting and/or papillotomy. Our review of 53 cases of EHDI reported in the English-language literature has focused on the evolving role of ERCP in diagnosis and treatment of these injuries. Diagnostic and treatment algorithms incorporating ERCP have been designed to help systematize and simplify the management of EHDI. An illustrative case is reported of blunt traumatic injury involving both the extrahepatic portion of the left hepatic duct and its confluence with the right hepatic duct. This injury was successfully diagnosed and treated using ERCP.

    Fluorescence intraoperative cholangiography (IOC) is a potential alternative for identifying anatomical variation and preventing iatrogenic bile duct injuries by using the near-infrared probe indocyanine green (ICG). However, the dynamic process and mechanism of fluorescence IOC have not been elucidated in previous publications. Herein, the optical properties of the complex of ICG and bile, dynamic fluorescence cholangiography and iatrogenic bile duct injuries were investigated. The emission spectrum of ICG in bile peaked at 844 nm and ICG had higher tissue penetration. Extrahepatic bile ducts could fluoresce 2 min after intravenous injection, and the fluorescence intensity reached a peak at 8 min. In addition, biliary dynamics were observed owing to ICG excretion from the bile ducts into the duodenum. Quantitative analysis indicated that ICG-guided fluorescence IOC possessed a high signal to noise ratio compared to the surrounding peripheral tissue and the portal vein. Fluorescence IOC was based on rapid uptake of circulating ICG in plasma by hepatic cells, excretion of ICG into the bile and then its interaction with protein molecules in the bile. Moreover, fluorescence IOC was sensitive to detect bile duct ligation and acute bile duct perforation using ICG in rat models. All of the results indicated that fluorescence IOC using ICG is a valid alternative for the cholangiography of extrahepatic bile ducts and has potential for measurement of biliary dynamics.

    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

    Hepatitis C virus (HCV) affects millions of people worldwide, and an estimated 3.2 million people in the United States. HCV is a hepatotropic and lymphotropic virus that causes not only liver disease, but also a significant number of extrahepatic manifestations (EHMs). Up to 74% of patients affected by HCV will have HCV-related EHMs of some severity in their lifetime. The EHMs vary from simple cutaneous palpable purpura to complex lymphoproliferative disorders, including lymphomas and immune-complex deposit diseases causing local and/or systemic complications. Mixed cryoglobulinemia (MC) is manifested by multiple systemic organ involvement, mainly skin, kidney, peripheral nerves, and salivary glands, and less frequently causes widespread vasculitis and malignant lymphoma. MC affects up to 3% of HCV-infected patients with cryoglobulinemia of clinical significance, i.e. >6%. Severe disease requires immunosuppressive or plasma exchange therapy. HCV prevalence in the United States in patients with porphyria cutanea tarda (PCT) was reported to be 66%, much higher than that in general population. Therefore, all patients with PCT should be screened for HCV. The skin rash of PCT varies from large blisters to small vesicles and/or milia on the hands. Skin manifestations due to PCT usually respond to anti‐HCV treatment together with reducing skin sun exposure, avoiding triggers, having routine phlebotomy (especially for people with chronic iron overload states), and using chloroquine. Lichen planus (LP), which typically affects both the skin and oral mucosa is a chronic inflammatory disease of squamous cell origin affecting about 1% of the worldwide population. The prevalence of HCV in patients with LP varies based on geographic location. We review here the basic pathophysiology, clinical features, and management of dermatologic manifestations of HCV.

    Synchronous double cancers of the bile duct are exceptionally rare. We here report a case of synchronous squamous cell carcinoma and adenocarcinoma of the extrahepatic bile duct. A 67-year-old Asian man visited our clinic complaining of jaundice and dark urine. Direct hyperbilirubinemia and an elevated cancer antigen 19-9 level were detected. Preoperative abdominal computed tomography and positron emission tomography showed two masses at the bifurcation of the common hepatic duct and at the distal common bile duct. After biliary drainage, we performed radical pylorus-preserving pancreaticoduodenectomy, without resection margin involvement. Pathological findings revealed that the proximal lesion was a squamous cell carcinoma and that the distal lesion was an adenocarcinoma. Both cholangiocarcinomas were confined to the fibromuscular layer, and there was no communication between the two tumors. Multiple conglomerated metastatic tumors were detected in his liver 3 months after surgery. He died 8 months after diagnosis. The disease displayed very aggressive behavior and a very poor prognosis. The only chance for long-term survival is treatment with radical resection. Preoperative positron emission tomography-computed tomography is useful in detecting occult cancer.

    The epidemiology of biliary tract cancers (BTC) varies between geographical regions and has changed over time globally. We investigated the incidence and mortality trends of patients diagnosed with BTC over a 20-year period in Austria. Patients diagnosed with intrahepatic (iCCC)/extrahepatic cholangiocarcinoma (eCCC), ampullary carcinoma, gall bladder carcinoma (GBC), overlapping lesions or unspecified carcinomas of the biliary tract and liver were included. Data on age-adjusted incidence were obtained from the Austrian National Cancer Registry which compiles data on all newly diagnosed cancers. Data on age-adjusted mortality were obtained from the national death registry (Statistics Austria). Between 1990 and 2009, 15201 patients were diagnosed with BTC (m/f=42/58%; mean age, 73 years). The median survival of all patients with BTC was 4.8 months with a 1-/5-year survival rate of 31%/10%. In iCCC, the incidence and mortality rates increased from 1990 to 2009 in both men and women while in eCCC, the incidence and mortality rates decreased over time in both sexes. In ampullary carcinoma, the incidence slightly decreased in men and remained stable in women. The mortality rate remained stable in both sexes. In GBC, the age-adjusted incidence and mortality rates dramatically decreased in both sexes. GBC and iCCC were the most common entities amongst BTC. While incidence and mortality rates of iCCC increased in men and women over time, incidence and mortality rates of eCCC and GBC decreased in both sexes. Other carcinomas of the biliary tract i.e. ampullary carcinoma were rarely diagnosed. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Mixed adenoneuroendocrine carcinomas, spindle cell carcinomas, and clear cell carcinomas are all rare tumors in the biliary tract. We present the first case, to our knowledge, of an extrahepatic bile duct carcinoma composed of all three types. A 65-year-old man with prior cholecystectomy presented with painless jaundice, vomiting, and weight loss. CA19-9 and alpha-fetoprotein (AFP were elevated. Cholangioscopy revealed a friable mass extending from the middle of the common bile duct to the common hepatic duct. A bile duct excision was performed. Gross examination revealed a 3.6 cm intraluminal polypoid tumor. Microscopically, the tumor had foci of conventional adenocarcinoma (CK7-positive and CA19-9-postive surrounded by malignant-appearing spindle cells that were positive for cytokeratins and vimentin. Additionally, there were separate areas of large cell neuroendocrine carcinoma (LCNEC. Foci of clear cell carcinoma merged into both the LCNEC and the adenocarcinoma. Tumor invaded through the bile duct wall with extensive perineural and vascular invasion. Circumferential margins were positive. The patient’s poor performance status precluded adjuvant therapy and he died with recurrent and metastatic disease 5 months after surgery. This is consistent with the reported poor survival rates of biliary mixed adenoneuroendocrine carcinomas.

    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

    The aim of this study was to establish the role played by jejunal veins in hepatopetal flow after biliary-enteric anastomosis and to evaluate the helical CT features of hepatopetal flow through the anastomosis. We retrospectively analyzed helical CT images of the liver in 31 patients with biliary-enteric anastomosis who underwent hepatic angiography with (n=13) or without (n=18) CT arterial portography within 2 weeks of the CT examination during the last 4 years. Arterial portography showed hepatopetal flow through small vessels located (communicating veins) between the elevated jejunal veins and the intrahepatic portal branches in two (9%) of 22 patients with a normal portal system. Helical CT showed focal parenchymal enhancement around the anastomosis in these two patients. All nine patients with extrahepatic portal vein occlusion (100%) had hepatopetal flow through the anastomosis, and four of the nine had decreased portal flow. CT revealed small communicating veins in two of these four patients. In five patients with normal portal perfusion despite extrahepatic portal vein occlusion, CT detected dilated communicating veins and elevated jejunal veins. The presence of communicating veins and/or focal parenchymal enhancement around the anastomosis indicates hepatopetal flow through the elevated jejunal veins.

    The term portal biliopathy (PB) is used to describe the biliary abnormalities associated with portal hypertension. Between 5% and 30% of patients with PB develop biliary obstruction. We report on a patient with extrahepatic biliary obstruction caused by PB that was successfully managed with an intrahepatic segment 3 bypass. The traditional surgical approach for a patient with extrahepatic biliary obstruction caused by PB would be a portosystemic shunt followed by a hepaticojejenostomy if the jaundice persited. An intrahepatic segment 3 bypass provides definitive treatment ensuring biliary decompression and stone removal in a single procedure in appropriately selected patients.

    Acute obstructive suppurative cholangitis (AOSC) due to biliary lithiasis is a life-threatening condition that requires urgent biliary decompression. 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.

  3. Cholangiopathy with Respect to Biliary Innate Immunity

    Directory of Open Access Journals (Sweden)

    2012-01-01

    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 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.

    Full Text Available Chronic obstructive pulmonary disease (COPD is a preventable, treatable disease with significant extrapulmonary manifestations that could affect negatively its course in some patients. Hepatitis C virus infection (HCV, on the other hand, is associated with a number of extrahepatic manifestations. COPD patients have increased prevalence of HCV and patients with HCV, especially older ones, have increased prevalence and faster progression of COPD. HCV infection exerts long-term effects on lung tissue and is an additional risk factor for the development of COPD. The presence of HCV is associated with an accelerated loss of lung function in COPD patients, especially in current smokers. COPD could represent extrahepatic manifestation associated with HCV infection. The aim of this article was to review the literature on prevalence of HCV in COPD and vice versa, pathogenetic link and the consequences of their mutual existence.

    Full Text Available Background: Biliary tract cancers (BTCs are rare and heterogeneous group of tumors classified anatomically into intrahepatic and extrahepatic bile ducts and gallbladder adenocarcinomas. Patient-derived tumor cell (PDC models with genome analysis can be a valuable platform to develop a method to overcome the clinical barrier on BTCs. Material and Methods: Between January 2012 and June 2015, 40 BTC patients’ samples were collected. PDCs were isolated and cultured from surgical specimens, biopsy tissues, or malignant effusions including ascites and pleural fluid. Genome analysis using targeted panel sequencing as well as digital multiplexed gene analysis was applied to PDCs as well as primary tumors. Results: Extrahepatic cholangiocarcinoma (N = 15, 37.5%, intrahepatic cholangiocarcinoma (N = 10, 25.0%, gallbladder cancer (N = 14, 35.0%, and ampulla of Vater cancer (N = 1, 2.5% were included. We identified 15 mutations with diverse genetic alterations in 19 cases of BTC from primary tumor specimens. The most common molecular alterations were in TP53 (8/19, 42.1%, including missense mutations such as C242Y, E285K, G112S, P19T, R148T, R248Q, and R273L. We also detected two NRAS mutations (G12C and Q61L, two KRAS mutations (G12A and G12S, two ERBB2 mutations (V777L and pM774delinsMA and amplification, and three PIK3CA mutations (N345K, E545K, and E521K. PDC models were successfully established in 27 of 40 samples (67.5%, including 22/24 from body fluids (91.7% and 5/16 from tissue specimens (31.3%. Conclusions: PDC models are promising tools for uncovering driver mutations and identifying rational therapeutic strategies in BTC. Application of this model is expected to inform clinical trials of drugs for molecular-based targeted therapy.

    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.

    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

    Prophylactic combined extrahepatic bile duct resection remains controversial for locally advanced gallbladder carcinoma without extrahepatic bile duct invasion. The aim of this study is to resolve this issue and establish an appropriate surgery for locally advanced gallbladder carcinoma. A total of 52 patients underwent surgical resection combined with extrahepatic bile duct resection for locally advanced gallbladder carcinoma without extrahepatic bile duct invasion, and their medical records were retrospectively reviewed for microvessel invasion (MVI), including lymphatic, venous, and/or perineural invasions, around the extrahepatic bile duct. Of the 52 patients, 8 (15 %) had MVI around the extrahepatic bile duct. All of the 8 patients had Stage IV disease. According to a survival analysis of the 50 patients who tolerated surgery, MVIs around the extrahepatic bile duct and distant metastasis were identified as independent prognostic factors. Survival for patients with MVI around the extrahepatic bile duct was dismal, with a lack of 2-year survivors. MVI around the extrahepatic bile duct is a sign of extremely locally advanced gallbladder carcinoma; therefore, prophylactic combined bile duct resection has no survival impact for patients without extrahepatic bile duct invasion.

  15. Expression and localization of sterile alpha motif domain containing 5 is associated with cell type and malignancy of biliary tree.

    Full Text Available Cholangiocarcinoma (CC is a type of relatively rare neoplasm in adenocarcinoma. The characteristics of CCs as well as biliary epithelial cells are heterogeneous at the different portion of the biliary tree. There are two candidate stem/progenitor cells of the biliary tree, i.e., biliary tree stem/progenitor cell (BTSC at the peribiliary gland (PBG of large bile ducts and liver stem/progenitor cell (LPC at the canals of Hering of peripheral small bile duct. Although previous reports suggest that intrahepatic CC (ICC can arise from such stem/progenitor cells, the characteristic difference between BTSC and LPC in pathological process needs further investigation, and the etiology of CC remains poorly understood. Here we show that Sterile alpha motif domain containing 5 (SAMD5 is exclusively expressed in PBGs of large bile ducts in normal mice. Using a mouse model of cholestatic liver disease, we demonstrated that SAMD5 expression was upregulated in the large bile duct at the hepatic hilum, the extrahepatic bile duct and PBGs, but not in proliferating intrahepatic ductules, suggesting that SAMD5 is expressed in BTSC but not LPC. Intriguingly, human ICCs and extrahepatic CCs exhibited striking nuclear localization of SAMD5 while the normal hilar large bile duct displayed slight-to-moderate expression in cytoplasm. In vitro experiments using siRNA for SAMD5 revealed that SAMD5 expression was associated with the cell cycle regulation of CC cell lines.SAMD5 is a novel marker for PBG but not LPC in mice. In humans, the expression and location of SAMD5 could become a promising diagnostic marker for the cell type as well as malignancy of bile ducts and CCs.

    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.

    Biliary intraepithelial neoplasia (BilIN) is a precursor lesion of hilar/perihilar and extrahepatic cholangiocarcinoma. BilIN represents the process of multistep cholangiocarcinogenesis and is the biliary counterpart of pancreatic intraepithelial neoplasia (PanIN). This study was performed to clarify the histological characteristics of BilIN in relation to PanIN. Using paraffin-embedded tissue sections of surgically resected specimens of cholangiocarcinoma associated with BilIN and pancreatic ductal adenocarcinoma associated with PanIN, immunohistochemical staining was performed using primary antibodies against MUC1, MUC2, MUC5AC, cyclin D1, p21, p53, and S100P. For mucin staining, Alcian blue pH 2.5 was used. Most of the molecules examined here showed similar expression patterns in BilIN and PanIN, in which their expression tended to increase along with the increase in atypia of the epithelial lesions. Significant differences were observed in the increase in mucin production and the expression of S100P in PanIN-1 and the expression of p53 in PanIN-3, when compared with those in BilIN of a corresponding grade. These results suggest that cholangiocarcinoma and pancreatic ductal adenocarcinoma share, at least in part, a common carcinogenic process and further confirm that BilIN can be regarded as the biliary counterpart of PanIN.

    Hydatid disease (HD) is a parasitic infection caused by the larvae of a tapeworm that is endemic to many regions around the world-South America, Africa, and Asia, in particular. Humans are infected as intermediate hosts in the parasite's life cycle; thus, HD can be seen in persons living in areas where animal husbandry is practiced. However, owing to the varied patterns of migration and immigration during the past several decades, HD can be diagnosed in individuals living anywhere. The liver is the most common organ involved, with hepatic HD accounting for the majority of published cases. However, HD can affect multiple organs and tissues other than the liver, including the spleen, kidneys, lungs, heart, peritoneum, muscles, and brain. Knowledge of the route of spread, clinical findings at presentation, and possible complications involving each extrahepatic location can be useful for the radiologist when evaluating imaging findings in patients suspected of having HD. The ultrasonographic, computed tomographic, and magnetic resonance imaging findings of extrahepatic hydatid lesions frequently simulate those of hepatic HD, as long as rupture, bleeding, and/or superimposed bacterial infection has not occurred. Specific features of HD seen at different extrahepatic sites can help tailor the diagnosis. The differential diagnoses that can mimic HD at every nonhepatic location should be considered, as many of these entities are common, especially in nonendemic areas. © RSNA, 2017.

    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.

Development of in vitro systems for culturing biliary epithelial cells has enabled functional studies which increasingly show that this is far from true, and that biliary epithelial cells do have important functional roles. Disruption of these functions may be involved in the generation of pathology. Most functional studies to date have utilised cells i...

    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.

  10. 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.

    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

    To investigate the association between preoperative fecal organic acid concentrations and the incidence of postoperative infectious complications in patients undergoing major hepatectomy with extrahepatic bile duct resection for biliary malignancies. The fecal samples of 44 patients were collected before undergoing hepatectomy with bile duct resection for biliary malignancies. The concentrations of fecal organic acids, including acetic acid, butyric acid, and lactic acid, and representative fecal bacteria were measured. The perioperative clinical characteristics and the concentrations of fecal organic acids were compared between patients with and without postoperative infectious complications. Among 44 patients, 13 (30%) developed postoperative infectious complications. Patient age and intraoperative bleeding were significantly greater in patients with postoperative infectious complications compared with those without postoperative infectious complications. The concentrations of fecal acetic acid and butyric acid were significantly less, whereas the concentration of fecal lactic acid tended to be greater in the patients with postoperative infectious complications. The calculated gap between the concentrations of fecal acetic acid plus butyric acid minus lactic acid gap was less in the patients with postoperative infectious complications (median 43.5 vs 76.1 μmol/g of feces, P = .011). Multivariate analysis revealed that an acetic acid plus butyric acid minus lactic acid gap acid profile (especially low acetic acid, low butyric acid, and high lactic acid) had a clinically important impact on the incidence of postoperative infectious complications in patients undergoing major hepatectomy with extrahepatic bile duct resection.

    Full Text Available Background and Aim. Neonatal hemochromatosis (NH is characterised by severe liver injury and extrahepatic siderosis sparing the reticuloendothelial system. Its aetiology is obscure, although it has been proposed as an alloimmune disease, resulting from immunological reaction to self-antigens (alloantigens which the body recognizes as foreign. We studied an infant with NH and his mother whose sera contained antimitochondrial antibody (AMA, the hallmark of primary biliary cirrhosis (PBC. Material and Methods. To investigate the origin of AMA in the infant, we studied isotype distributions in serum from the mother and infant. Serum samples were obtained at diagnosis of NH, after liver transplantation (LT; age 1 month, and over the ensuing 17 months. Results. At NH diagnosis, infant and maternal serum contained AMA of the IgG isotype, predominantly of the G3 and G1 subclasses. AMA strongly reacted against the pyruvate dehydrogenase complex E2 subunit (PDC-E2, the major PBC-specific AMA autoantigen. Anti-PDC-E2 responses in both infant and mother declined over time, being present 2 months after LT (mother and child and absent 10 months later (mother and 17 months later (child. Conclusion. The association of maternally transferred IgG1 and IgG3 subclass AMA with the appearance of liver damage in an infant with NH may suggest a causal link between antibody and liver damage.

    Green tea and coffee consumption may decrease the risk of some types of cancers. However, their effects on biliary tract cancer (BTC) have been poorly understood. In this population-based prospective cohort study in Japan, we investigated the association of green tea (total green tea, Sencha, and Bancha/Genmaicha) and coffee consumption with the risk for BTC and its subtypes, gallbladder cancer, and extrahepatic bile duct cancer. The hazard ratios and 95% confidence intervals were calculated using the Cox proportional hazard model. A total of 89 555 people aged 45-74 years were enrolled between 1995 and 1999 and followed up for 1 138 623 person-years until 2010, during which 284 cases of BTC were identified. Consumption of >720 mL/day green tea was significantly associated with decreased risk compared with consumption of ≤120 mL/day (hazard ratio = 0.67 [95% confidence interval, 0.46-0.97]), and a non-significant trend of decreased risk associated with increased consumption was observed (P-trend = 0.095). In the analysis according to the location of the primary tumor, consuming >120 mL green tea tended to be associated with decreased risk of gallbladder cancer and extrahepatic bile duct cancer. When Sencha and Bancha/Genmaicha were analyzed separately, we observed a non-significant trend of decreased risk of BTC associated with Sencha but no association with Bancha/Genmaicha. For coffee, there was no clear association with biliary tract, gallbladder, or extrahepatic bile duct cancer. Our findings suggest that high green tea consumption may lower the risk of BTC, and the effect may be attributable to Sencha consumption. © 2015 The Authors.

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Ischemia-reperfusion (I-R injury after liver transplantation (LT induces intra- and/or extrahepatic nonanastomotic ischemic-type biliary lesions (ITBLs. Subsequent bile duct stricture is a significant cause of morbidity and even mortality in patients who underwent LT. Although the pathogenesis of ITBLs is multifactorial, there are three main interconnected mechanisms responsible for their formation: cold and warm I-R injury, injury induced by cytotoxic bile salts, and immunological-mediated injury. Cold and warm ischemic insult can induce direct injury to the cholangiocytes and/or damage to the arterioles of the peribiliary vascular plexus, which in turn leads to apoptosis and necrosis of the cholangiocytes. Liver grafts from suboptimal or extended-criteria donors are more susceptible to cold and warm I-R injury and develop more easily ITBLs than normal livers. This paper, focusing on liver I-R injury, reviews the risk factors and mechanisms leading to ITBLs following LT.

    Autochthonous (locally acquired) hepatitis E is increasingly recognised in developed countries, and is thought to be a porcine zoonosis. A range of extra-hepatic manifestations of hepatitis E infection have been described, but have never been systematically studied. To report the extra-hepatic manifestations of hepatitis E virus. Retrospective review of data of 106 cases of autochthonous hepatitis E (acute n = 105, chronic n = 1). Eight (7.5%) cases presented with neurological syndromes, which included brachial neuritis, Guillain-Barré syndrome, peripheral neuropathy, neuromyopathy and vestibular neuritis. Patients with neurological syndromes were younger (median age 40 years, range 34-92 years, P = 0.048) and had a more modest transaminitis (median ALT 471 IU/L, P = 0.015) compared to cases without neurological symptoms [median age 64 years (range 18-88 years), median ALT 1135 IU/L]. One patient presented with a cardiac arrhythmia,twelve patients (11.3%) presented with thrombocytopenia, fourteen (13.2%) with lymphocytosis and eight (7.5%) with a lymphopenia, none of which had any clinical consequence. Serum electrophoresis was performed in 65 patients at presentation, of whom 17 (26%) had a monoclonal gammopathy of uncertain significance. Two cases developed haematological malignancies, acute myeloid leukaemia and duodenal plasmacytoma, 18 and 36 months after presenting with acute hepatitis E infection. A range of extra-hepatic manifestations can occur with hepatitis E. Neurological and haematological features of hepatitis E infection are relatively frequent in this UK cohort, and result in significant morbidity which warrants further study. © 2014 John Wiley & Sons Ltd.

    We report an extremely rare case of a diffuse hepatic hemangiomatosis without extrahepatic involvement in an adult. The imaging findings of this tumor were similar to those of a hepatic hemangioma and included contrast enhancement with a centripetal filling pattern of the entire hepatic tumor on the delayed phase of a dynamic CT and inhomogeneous diffuse uptake of the entire tumor on blood-pool images obtained five hours later on a 99mTc-labeled red blood cell scan. Despite its rarity, diffuse hepatic hemangiomatosis can be suggested in adult patients with diffusely involved hepatic tumors showing the radiological findings of a hepatic hemangioma.

    This study aimed to investigate post-recurrence overall survival (PROS) in patients with recurrent extrahepatic cholangiocarcinoma (EHC) and to indicate which groups of patients need active salvage treatments. We retrospectively reviewed the records of 251 consecutive patients who underwent curative surgery followed by adjuvant chemoradiotherapy for EHC. Among these, 144 patients experienced a recurrence and were included for further analysis. The median PROS was 7 months (range, 1-130). In multivariate analysis, poorly differentiated histology, short disease-free survival, poor performance status, and elevated CA 19-9 were identified as significant prognosticators for poor PROS. Based on this, we stratified study patients into three categories by the number of risk factors: group 1 (0 or 1 factors), group 2 (2 factors) and group 3 (3-4 factors). Median PROS for groups 1, 2, and 3 were 13, 7, and 5 months, respectively (p < 0.001). Group 1 patients showed a significant benefit from salvage treatment, but groups 2 and 3 did not demonstrate clear benefit. In addition, we developed a nomogram to specifically identify individual patient's prognosis. Our simple risk stratification as well as proposed nomogram can classify patients into subgroups with different prognosis and will help facilitate personalized strategies after recurrence.

    To evaluate thread sign of biliary intraductal papillary mucinous neoplasm (B-IPMN) on magnetic resonance imaging (MRI). Thread sign was defined as intraductal linear or curvilinear hypointense striations. Two radiologists independently evaluated the presence and location of thread sign on MR cholangiography (thin-slice, thick-slab and 3D MRC) and axial MR images (T2 TSE, T2 HASTE and DWI) in patients with B-IPMN (n = 38) and in matched control groups with benign (n = 36) or malignant (n = 35) biliary diseases. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of thread sign for diagnosing B-IPMN were evaluated. Thread sign was observed only in patients with B-IPMN on MRC (44.7-52.6 % [17/38-20/38], P < 0.001) and axial MR images (31.6 % [12/38], P < 0.001), except in one patient with recurrent pyogenic cholangitis on MRC (2.8 %, 1/36). The sensitivity, specificity, accuracy, PPV and NPV of thread sign for diagnosing B-IPMN on MRC were 0.53, 0.99, 0.83, 0.95 and 0.80, respectively (reader 1) and 0.45, 1.0, 0.81, 1.0 and 0.77, respectively (reader 2). Thread sign was detected mainly at the extrahepatic bile duct (52.6 %, 20/38). B-IPMN can manifest thread sign, a novel specific MR finding, mainly at the extrahepatic bile duct on MRI, especially on MRC. • Some B-IPMNs manifest thread sign within the bile ducts on MRI. • Thread sign is a highly specific finding for B-IPMN on MRI. • MRC is superior to axial T2WI and DWI for detecting thread sign.

    Extrahepatic biliary atresia (EHBA) is a rare disease characterized by progressive and obliterative cholangiopathy in infants and is one of the major causes of secondary vitamin K deficiency bleeding (VKDB) due to cholestasis-induced fat malabsorption. Breast feeding increases the tendency of bleeding in EHBA patients because breast milk contains low amounts of vitamin K. A 2-month-old female infant unexpectedly died, with symptoms of vomiting and jaundice prior to death. She had been born by uncomplicated vaginal delivery and exhibited normal growth and development with breastfeeding. There was no history of trauma. She received vitamin K prophylaxis orally. In an emergency hospital, a CT scan showed a right intracranial hematoma and mass effect with midline shift to the left. In the postmortem examination, severe atresia was observed in the whole extrahepatic bile duct. Histologically, cholestasis, periductal fibrosis, and distorted bile ductules were noted. The gallbladder was not identified. A subdural hematoma and cerebellar tonsillar herniation were found; however, no traumatic injury in any part of the body was observed. Together, these findings suggest that the subdural hemorrhage was caused by secondary vitamin K deficiency resulting from a combination of cholestasis-induced fat malabsorption and breastfeeding. Subdural hemorrhage by secondary VKDB sometimes occurs even when vitamin K prophylaxis is continued. This case demonstrated that intrinsic factors, such as secondary VKDB (e.g., EHBA, neonatal hepatitis, chronic diarrhea), should also be considered in infant autopsy cases presenting with subdural hemorrhage.

  4. Biliary Innate Immunity: Function and Modulation

    Directory of Open Access Journals (Sweden)

    Kenichi Harada

    2010-01-01

    Full Text Available Biliary innate immunity is involved in the pathogenesis of cholangiopathies in patients with primary biliary cirrhosis (PBC and biliary atresia. 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.

    Although chemotherapy is widely recommended for patients with metastatic biliary tract cancer, the natural course of these patients, especially those with good performance status who are indicated for chemotherapy, is not known. We retrospectively reviewed patients with metastatic or locally advanced biliary cancer who were diagnosed at six cancer centers. Patients were eligible if they had good performance (ECOG 0-2) and no history of any treatment for cancer. The primary objective was to evaluate the survival time of patients with advanced biliary cancer with good performance who were untreated. Of the 1677 patients, 204 met the inclusion criteria. The median age and overall survival were 72.0 years and 7.1 months. Overall survival (months) by location was 4.7 for intrahepatic, 9.7 for extrahepatic, 4.4 for gallbladder and 11.2 for ampulla of vater cancer. In subgroup analysis, overall survival of locally advanced biliary cancer was 13.8 months and that of patients with normal carcinoembryonic antigen/carbohydrate antigen 19-9 was 10.6 months. In multivariate analysis, variables that were associated with poor prognosis were metastatic biliary cancer [hazard ratio 2.19 (P = 0.001)], high baseline carcinoembryonic antigen level (defined as >4.0 ng/ml) [hazard ratio 1.51 (P = 0.024)] and high baseline carbohydrate antigen 19-9 level (defined as >100 U/ml) [hazard ratio 1.93 (P = 0.001)]. Advanced biliary tract cancer with good performance status showed modest survival without any treatment. Furthermore, subgroup analysis showed that patients with normal carbohydrate antigen 19-9 or carcinoembryonic antigen level or locally advanced status had favorable survival. Further studies comparing the outcome of chemotherapy with that of best supportive care in patients with unresectable biliary tract cancer are warranted. © The Author 2015.

  9. Microwell scaffolds for the extrahepatic transplantation of islets of Langerhans.

    Mijke Buitinga

    Full Text Available Allogeneic islet transplantation into the liver has the potential to restore normoglycemia in patients with type 1 diabetes. However, the suboptimal microenvironment for islets in the liver is likely to be involved in the progressive islet dysfunction that is often observed post-transplantation. This study validates a novel microwell scaffold platform to be used for the extrahepatic transplantation of islet of Langerhans. Scaffolds were fabricated from either a thin polymer film or an electrospun mesh of poly(ethylene oxide terephthalate-poly(butylene terephthalate (PEOT/PBT block copolymer (composition: 4000PEOT30PBT70 and were imprinted with microwells, ∼400 µm in diameter and ∼350 µm in depth. The water contact angle and water uptake were 39±2° and 52.1±4.0 wt%, respectively. The glucose flux through electrospun scaffolds was three times higher than for thin film scaffolds, indicating enhanced nutrient diffusion. Human islets cultured in microwell scaffolds for seven days showed insulin release and insulin content comparable to those of free-floating control islets. Islet morphology and insulin and glucagon expression were maintained during culture in the microwell scaffolds. Our results indicate that the microwell scaffold platform prevents islet aggregation by confinement of individual islets in separate microwells, preserves the islet's native rounded morphology, and provides a protective environment without impairing islet functionality, making it a promising platform for use in extrahepatic islet transplantation.

  10. Extrahepatic manifestations associated with Chronic Hepatitis C Virus Infection

    Directory of Open Access Journals (Sweden)

    A. Flores-Chávez

    Full Text Available Summary Chronic hepatitis C virus (HCV infection has been associated with both organ-specific and systemic autoimmune diseases, with cryoglobulinemia being the most frequent associated disease. Experimental, virologic, and clinical evidence have demon-strated a close association between HCV infection and some systemic autoimmune diseases, especially Sjögren’s syndrome, but also rheumatoid arthritis and lupus. A higher prevalence of hematological processes has also been described in patients with HCV infection, including cytopenias and lymphoproliferative disorders (B-cell lymphoma. In addition, patients with chronic HCV infection have a higher frequency of other extrahepatic manifestations including endocrine, metabolic and cardiovascular disorders that may worse the prognosis of patients, along with neuropsychiatric manifestations and general symptoms that have a significant influence on the quality of life of the patient. Direct-acting antiviral therapies (DAAs that have recently begun to be used are providing the opportunity to effectively cure chronic HCV infection and reduce the burden of both hepatic and extrahepatic complications.

  11. Biliary Epithelial Apoptosis, Autophagy, and Senescence in Primary Biliary Cirrhosis

    Directory of Open Access Journals (Sweden)

    Motoko Sasaki

    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.

    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

    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.

  17. Percutaneous stenting of the portal vein prior to biliary bypass in a patient with chronic pancreatitis and portal biliopathy.

    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 Peribiliary glands (PBGs are located in the large intrahepatic and extrahepatic bile ducts. Although they were described many years ago, their functions have been elucidated only in the last couple of years when our group demonstrated that PBGs are niches of multipotent stem/progenitor cells of endodermal origin. These cells express genes of multipotency and can be rapidly differentiated in vitro into hepatocytes, cholangiocytes, and endocrine pancreatic cells. PBGs share common features, in terms of stem/progenitor cell niches, with pancreatic duct glands and colon crypts, glandular structures representing in the adult life the endodermal remnants of fetal life. PBG stem/progenitor cells participate in the renewal of surface biliary epithelium and are active players in chronic pathologies of the biliary tree as well as in cholangiocarcinomas (CCA. Specifically, a large amount of recent evidence indicates that the pure mucin-CCA originates from PBGs; this could explain the similarities with pancreatic ductal adenocarcinoma and colorectal cancer, which also originate from transformed gland cells. In this paper, we summarized our recent findings concerning structure and functions of PBGs with the implications for liver pathophysiology and, specifically, for cancers of the biliary tree.

    Rex shunt (mesenteric-to-left portal vein bypass) is considered a more physiologically rational treatment for EHPVO than other portosystemic systemic shunts in children. However, about 13.6% of children with EHPVO do not have usable left portal veins and up to 28.1%. Rex operations in children are not successful. Hence, a Rex shunt in these children was impossible. This study reports a novel approach by portal-to-right portal vein bypass for treatment of children with failed Rex shunts. Eight children (age 6.1years, range 3.5-8.9years) who underwent Rex shunts developed recurrent gastrointestinal bleeding and hypersplenism 13months (11-30months) postoperatively. After ultrasound confirmation of blocked shunt, they underwent exploration. Three patients were found to have right portal vein agenesis. Five patients (62.5%) were found to have the patent right portal vein, with the diameter of 3-6mm. Four patients underwent bypass between the main portal vein in the hepatoduodenal ligament and the right portal vein by interposing an inferior mesenteric vein autograft, whereas the remaining patient underwent a bypass using ileal mesenteric vein autograft. The operations took 2.3h (1.9-3.5h). The estimated blood loss was 50ml (30-80ml), with no complication. The portal venous pressure dropped from 34.6cmH2O (28-45 cmH2O) before the bypass to 19.6cmH2O (14-24cmH2O) after the bypass. The 5 patients were followed up for 10.2months (4-17months) and the post-operative ultrasound and CT angiography confirmed the patency of all the grafts and disappearance of the portal venous cavernova in all five patients. The portal-to-right portal vein bypass technique is feasible and safe for treatment of children with EHPVO who have had failed Rex shunts. Our preliminary result indicates that this technique extends the success of Rex shunt from left portal vein to right portal vein and open a new indication of physiological shunt for some of the children who not only have had failed Rex shunts or but also are not suitable for the Rex shunts.

    Portal biliopathy producing intrahepatic and extrahepatic biliary ductal abnormalities from portal hypertension, particularly with extrahepatic portal vein obstruction (EHPVO) is common. A majority of these patients are asymptomatic, but occasionally there is symptomatic biliary obstruction, and cholangitis and choledocholithiasis. To explore the principles of diagnosis and treatment of portal biliopathy. To review the literature of portal biliopathy. Endoscopic sphincterotomy, stone extraction and supportive drainage could effectively relieve cholangitis when jaundice is associated with common bile duct stones. Definitive decompressive portal-system vein shunting operation and choledocho-jejunostomy are sometimes required when biliary obstruction is recurrent and progressive.

    Full Text Available Introduction: the problem of the iatrogenic lesions of the main biliary pathways is far from being completely clarified and still represents a serious surgical situation, during both open and laparoscopic surgeries. The outcome of these situations is closely linked with the actual moment of discovery of the lesion and the surgical methods for repairing such defects and implies a great number of options, such as reconstructive, derivative and substitutive techniques. Objectives: the goal of this paper is to present an algorithm of choices and their consequences for clinical conduit in the case of iatrogenic biliary lesions discovered in the course of open or laparoscopic procedures of the main biliary pathways, based on our experience. Material and method: We present a multicentric retrospective study of 53 cases of lesions following open and laparoscopic procedures, from a larger lot of 10.015 surgeries on extrahepatic biliary ducts recorded during a 40 years period of time, in 2 clinical hospitals. Out of these, 2127 interventions were strictly focused on the common bile duct, for various pathology. Conclusion: The choice of the optimum method is strictly correlated with the morphological nature of the lesion, which is different from one stage to the other, depending upon the moment of detection, and therefore have different surgical implications.

    Background Nonanastomotic biliary strictures (NAS) remain a frequent complication after orthotopic liver transplantation (OLT). The aim of this study was to evaluate whether magnetic resonance cholangiopancreatography (MRCP) could be used to detect NAS and to grade the severity of biliary strictures. Methods In total, 58 patients after OLT from 2 Dutch transplantation centers in whom endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography and MRCP were performed within less than 6 months apart were included in the study. Of these patients, 41 had NAS and 17 were without NAS based on endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography and follow-up. Four radiologists—2 from each center—used an adapted validated classification—termed “Leiden Biliary Stricture Classification” “(LBSC)—to evaluate the MRCP examinations independently. In this classification, NAS severity is assessed in 4 hepatobiliary regions. Interobserver agreement of the severity score for each region was calculated with the κ statistics. Results Optimal cutoff value of the LBSC to detect the presence of NAS with MRCP was calculated at 3 points or greater for all readers. Applying this cutoff sensitivity for each reader was greater than 90%, with a specificity of 50% to 82%, positive predictive value of 86% to 91%, and negative predictive value of 80% to 100%. The MRCP performance was better in evaluation of the intrahepatic than of the extrahepatic bile ducts. The additional value of MRCP for grading severity of NAS was limited. Conclusions The MRCP with the LBSC is a reliable tool to detect or exclude NAS after OLT. Currently, MRCP cannot be used to reliably grade the severity of these strictures. PMID:27500210

    Full Text Available Abstract Background Biliary atresia (BA is a typical cholestatic neonatal disease, characterized by obliteration of intra- and/or extra-hepatic bile ducts. However, the mechanisms contributing to the pathogenesis of BA remain uncertain. Because of decreased bile flow, infectious complications and damaging endotoxemia occur frequently in patients with BA. The aim of this study was to investigate endotoxin levels in patients with BA and the relation of these levels with the expression of the endotoxin receptor, CD14. Methods The plasma levels of endotoxin and soluble CD14 were measured with a pyrochrome Limulus amebocyte lysate assay and enzyme-linked immunosorbent assay in patients with early-stage BA when they received the Kasai procedure (KP, in patients who were jaundice-free post-KP and followed-up at the outpatient department, in patients with late-stage BA when they received liver transplantation, and in patients with choledochal cysts. The correlation of CD14 expression with endotoxin levels in rats following common bile duct ligation was investigated. Results The results demonstrated a significantly higher hepatic CD14 mRNA and soluble CD14 plasma levels in patients with early-stage BA relative to those with late-stage BA. However, plasma endotoxin levels were significantly higher in both the early and late stages of BA relative to controls. In rat model, the results demonstrated that both endotoxin and CD14 levels were significantly increased in liver tissues of rats following bile duct ligation. Conclusions The significant increase in plasma endotoxin and soluble CD14 levels during BA implies a possible involvement of endotoxin stimulated CD14 production by hepatocytes in the early stage of BA for removal of endotoxin; whereas, endotoxin signaling likely induced liver injury and impaired soluble CD14 synthesis in the late stages of BA.

    Full Text Available Patients with chronic hepatitis C virus (HCV infection frequently have many extrahepatic manifestations, as persistent HCV infection often triggers lymphoproliferative disorders and metabolic abnormalities. These manifestations primarily include autoimmune disorders such as cryoglobulinemia, Sjögren’s syndrome, and autoimmune thyroid disorders. It has been well established that chronic HCV infection plays important roles in the production of non-organ-specific autoantibodies, including antinuclear antibodies and smooth muscle antibodies, and organ-specific autoantibodies such as thyroid autoantibodies. However, the clinical significance of autoantibodies associated with the extrahepatic manifestations caused by HCV infection has not been fully recognized. In this paper, we mainly focus on the relationship between extrahepatic manifestations and the emergence of autoantibodies in patients with HCV infection and discuss the clinical relevance of the autoantibodies in the extrahepatic disorders.

  7. Determining the optimal portal blood volume in a shunt before surgery in extrahepatic portal hypertension

    2016-04-01

    Full Text Available The aim of the study: To determine the necessary shunt diameter and assess the optimal portal blood volume in a shunt in children with extrahepatic portal hypertension before the portosystemic shunt surgery. Changes in the liver hemodynamics were studied in 81 children aged from 4 to 7 years with extrahepatic portal hypertension. We established that it is necessary to calculate the shunt diameter and the blood volume in a shunt in patients with extrahepatic portal hypertension before the portosystemic shunt surgery. It allows us to preserve the hepatic portal blood flow and effectively decrease the pressure in the portal system. Portosystemic shunt surgery in patients with extrahepatic portal hypertension performed in accordance with the individualized shunt volume significantly decreases portal pressure, preserves stable hepatic hemodynamics and prevents gastro-esophageal hemorrhage.

    Laparoscopic cholecystectomy due to cholelithiasis is associated with a higher risk of intraoperative lesions of biliary duct in comparison to classic surgery. Technical difficulties, a limited access to operating area, the presence of cholecystic adhesions and inflammatory lesions, as well as possible anomalies or anatomical variations of the extrahepatic biliary ducts pose the risk of damaging the biliary tract. At times, laparoscopic procedures are performed by surgeons with insufficient operator skills and qualifications. The medico-legal evaluation of intraoperative damage to the biliary tract with resulting complications--the so-called "biliary damage"--is very difficult. The presented analysis included six cases of intraoperative biliary ducts lesions evaluated by the Forensic Medicine Department, Medical University, Katowice. Three instances were associated with investigations carried out by public prosecutors in medical error cases, and in three others, civil cases were brought in the court, with the plaintiffs advancing a claim. While defining the scope of the management--both diagnostic, therapeutic and decision-making--in the pre-, intra- and postoperative period, attention was drawn to the prescriptive character of patient management in such cases, including indications for laparoscopic surgery, an increased potential therapeutic risk that also included a possibility of the patient developing "normal, typical" complications, referring the above factors to the scope and limits of the physician's professional and criminal liability and analyzing them to assess whether a medical error had been committed, or else the events had represented a therapeutic failure within the limits of the accepted therapeutic risk. A separate problem emphasized by the authors focused on difficulties in objective evaluation of health-associated consequences that might be defined in a tabular manner as long-term or permanent detriment to health.

    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.

    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.

  12. 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.

    2012-06-15

    Ultrasonography (US) is as an important tool for differentiation of obstructive and non-obstructive causes of jaundice in infants and children. Beyond two weeks of age, extrahepatic biliary atresia and neonatal hepatitis are the two most common causes of persistent neonatal jaundice: differentiation of extrahepatic biliary atresia, which requires early surgical intervention, is very important. Meticulous analysis should focus on size and configuration of the gallbladder and anatomical changes of the portahepatis. In order to narrow the differential diagnosis, combined approaches using hepatic scintigraphy, MR cholangiography, and, at times, percutaneous liver biopsy are necessary. US is useful for demonstrating choledochal cyst, bile plug syndrome, and spontaneous perforation of the extrahepatic bile duct

    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.

    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.

    We conducted this prospective nested case-control study for the hepatic artery and portal vein hemodynamic changes after orthotopic liver transplantation. A total 128 cases of orthotropic liver transplantation were analyzed, including 25 cases of ischemic type biliary lesions (ITBL). The portal vein and hepatic artery flow velocities were detected by ultrasound on days 28, 42, and 84 after liver transplantation.

    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.

    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.

    Diets that induce a high glycemic response might increase the risk of biliary tract cancer (BTC). We evaluated the hypothesis that diets with high glycemic load (GL) and high glycemic index (GI), which are measures of the glycemic effect of foods, are associated with an increased incidence of BTC. We used data from a population-based prospective study of 76,014 Swedish adults (age 45-83 years; 57% men) who were free of cancer and had completed a food-frequency questionnaire in the autumn of 1997. Incident cancer cases were ascertained by linkage with the Swedish Cancer Registry. Data were analyzed using Cox proportional hazards regression models. During a mean follow-up of 13.3 years (1,010,777 person-years), we identified 140 extrahepatic BTC cases (including 77 gallbladder cancers) and 23 intrahepatic BTC cases. A high dietary GL was associated with an increased risk of BTC. The multivariable relative risks for the highest versus lowest quartile of dietary GL were 1.63 (95% confidence interval (95% CI), 1.01-2.63) for extrahepatic BTC, 2.14 (95% CI, 1.06-4.33) for gallbladder cancer, and 3.46 (95% CI, 1.22-9.84) for intrahepatic BTC. Dietary GI was statistically significantly positively associated with risk of extrahepatic BTC and gallbladder cancer. We observed no statistically significant association between carbohydrate intake and BTC risk, although all associations were positive. Although these data do not prove a causal relationship, they are consistent with the hypothesis that high-GL and high-GI diets are associated with an increased risk of BTC.

    Though rosmarinic acid possesses nutritional, pharmaceutical, and toxic properties and shows therapeutic potential on liver diseases, its therapeutic effects against cholestatic liver diseases have not been proven. Using an extrahepatic cholestasis rat model by bile-duct ligation (BDL), daily oral administration of rosmarinic acid showed improvement effects on liver histology, serum biochemicals, ductular reaction, oxidative stress, inflammation, and fibrosis. Rosmarinic acid alleviated BDL-induced transforming growth factor beta-1 (TGF-β1) production and hepatic collagen deposition, and the anti-fibrotic effects were accompanied by reductions in matrix-producing cells and Smad2/3. BDL rats showed increased hepatic NF-κB/AP-1 activities, inflammatory cell infiltration/accumulation, and cytokine production, and these signs of hepatic inflammation were ameliorated by rosmarinic acid. Mechanistic study revealed an inhibitory effect of rosmarinic acid on the axis of the high mobility group box-1 (HMGB1)/toll-like receptor-4 (TLR4) in BDL rats. Results of cultured hepatic stellate cells further showed the impacts of rosmarinic acid which attenuated TGF-β1-induced stellate cell mitogenic and fibrogenic activation. Our findings support the concept that rosmarinic acid could serve as a hepatoprotective agent, and dietary rosmarinic acid supplementation may be beneficial in terms of improving cholestasis-related liver injury via mechanisms involving resolution of oxidative burden and down-regulation of HMGB1/TLR4, NF-κB, AP-1, and TGF-β1/Smad signaling.

    Full Text Available Cirrhosis and hepatocellular carcinoma are the prototypic complications of chronic hepatitis C virus infection in the liver. However, hepatitis C virus also affects a variety of other organs that may lead to significant morbidity and mortality. Extrahepatic manifestations of hepatitis C infection include a multitude of disease processes affecting the small vessels, skin, kidneys, salivary gland, eyes, thyroid, and immunologic system. The majority of these conditions are thought to be immune mediated. The most documented of these entities is mixed cryoglobulinemia. Morphologically, immune complex depositions can be identified in small vessels and glomerular capillary walls, leading to leukoclastic vasculitis in the skin and membranoproliferative glomerulonephritis in the kidney. Other HCV-associated entities include porphyria cutanea tarda, lichen planus, necrolytic acral erythema, membranous glomerulonephritis, diabetic nephropathy, B-cell non-Hodgkin lymphomas, insulin resistance, sialadenitis, sicca syndrome, and autoimmune thyroiditis. This paper highlights the histomorphologic features of these processes, which are typically characterized by chronic inflammation, immune complex deposition, and immunoproliferative disease in the affected organ.

    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.

    To study the differences in outcome and predictors of mortality in acute-on-chronic liver failure (ACLF) precipitated by hepatic or extrahepatic insults. Consecutive patients of cirrhosis with acute decompensation were prospectively included and followed up for 90 days from admission. ACLF was defined based on chronic liver failure (CLIF) acute-on-chronic liver failure in cirrhosis (CANONIC study) criteria. Acute worsening due to acute viral hepatitis A and E, hepatitis B flare, alcoholic hepatitis, autoimmune hepatitis flare, or drug-induced liver injury were categorized as hepatic ACLF and that due to bacterial infection, upper gastrointestinal bleed or surgery as extrahepatic ACLF. Patients with both hepatic and extrahepatic insults were included in combined insult group. Of 179 patients of acute decompensation, 122 had ACLF (hepatic insults 47 and extrahepatic insults 51). Alcohol (64.8%) was the most common etiology of cirrhosis while infection (36%) was the most common acute insult followed by alcoholic hepatitis (24.6%). Higher proportion of extrahepatic ACLF patients had history of prior decompensation than hepatic ACLF patients (62.7% vs. 27.7%, P liver failure-sequential organ failure assessment (CLIF-SOFA), model for end stage liver disease (MELD), integrated MELD score (iMELD), acute physiology and chronic health evaluation score (APACHE-II), and Child-Turcotte-Pugh score scores, respectively. There is no difference in mortality among hepatic and extrahepatic ACLF groups at 28 and 90 days. iMELD and CLIF-SOFA have highest AUROC to predict 28-day mortality in hepatic and extrahepatic ACLF groups, respectively.

    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.

  9. 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.

    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.

    Perioperative CA19-9 value in pancreato-biliary cancers has been recognized as a prognostic factor. Herein, we investigated survival differences and recurrence patterns after adjuvant chemoradiotherapy by perioperative CA19-9 change in surgically resected extrahepatic cholangiocarcinoma. Patients were divided into those with preoperative normal CA19-9 (Group 1, n = 52), those with high preoperative and normalized postoperative CA19-9 (Group 2, n = 80), and those with both high pre- and postoperative CA19-9 (Group 3, n = 21). Depending on the group defined above, the 5-year overall survival (OS) (59.6%, 38.7%, and 9.5%, P < 0.001) and disease-free survival (55.8%, 31.2%, and 9.5%, P < 0.001) between the three groups differed. On multivariable analysis in patients other than group 1, poor prognosticators for OS were high postoperative CA19-9 (HR 2.26, P = 0.008) and N1 disease (HR 2.33, P = 0.001). Group 3, compared with group 2, showed higher distant metastasis rate, shorter disease-free interval, and higher CA19-9 at the time of recurrence. Survival and recurrence patterns after adjuvant chemoradiotherapy are significantly affected by perioperative CA19-9 change. This may have important implications in patient selection for adjuvant chemoradiotherapy and clinical trial design. © 2017 Wiley Periodicals, Inc.

    The economic impact of extrahepatic manifestations of hepatitis C virus (HCV) infection remains unknown for France. To estimate the prevalence of extrahepatic manifestations of HCV and the direct medical costs associated with them. Estimates of 13 extrahepatic manifestations prevalence were obtained from (1) a retrospective data analysis of HCV-infected patients in a specialised centre and the baseline prevalence in the general French population and (2) an international systematic review. Per-patient-per-year costs to treat these manifestations were obtained from the literature, national databases or expert opinion. The impact of achieving HCV cure after anti-viral therapy was applied to the French healthcare costs. Using approach (1), increased prevalence rates in HCV patients compared to the general population were observed for most extrahepatic manifestations. The mean per-patient-per-year cost of these manifestations in the tertiary centre was 3296 € [95% CI 1829; 5540]. In France, HCV-extrahepatic manifestations amounted to a total cost of 215 million (M) € per year [144; 299]. Using approach (2), the mean per-patient-per-year cost was estimated to be 1117 €. The estimated total cost reduction in France associated with HCV cure was 13.9 M€ for diabetes, 8.6 M€ for cryoglobulinemia vasculitis, 6.7 M€ for myocardial infarction, 2.4 M€ for end-stage renal disease and 1.4 M€ for stroke. Extrahepatic manifestations of HCV infection substantially add to the overall economic burden of the disease in France. HCV cure after anti-viral therapy is expected to significantly reduce the total costs of managing these manifestations in France. © 2017 John Wiley & Sons Ltd.

    Background and Aims: Primary liver cancer remains still the common cause of cancer-related deaths globally and the prognosis for patients with extrahepatic metastasis is poor. The aim of our study was to assess extrahepatic metastatic pattern of different histological subtypes and evaluate prognostic effects of extrahepatic metastasis in patients with advanced disease. Methods: Based on the Surveillance, Epidemiology and End Results (SEER) database, eligible patients diagnosed with primary liver cancer was identified between 2010 to 2012. We adopted Chi-square test to compared metastasis distribution among different histological types. We compared survival difference of patients with different extrahepatic metastasises by Kaplan-Meier analysis. Cox proportional hazard models were performed to identify other prognostic factors of overall survival. Results: We finally identified 8677 patients who were diagnosed with primary liver cancer from 2010 to 2012 and 1775 patients were in distant metastasis stages. Intrahepatic cholangiocarcinoma was more invasive and had a higher percentage of metastasis compared with hepatocellular carcinoma. Lung was the most common metastasis and brain was the least common site for both hepatocellular carcinoma and intrahepatic cholangiocarcinoma. Extrahepatic metastasis could consider as an independent prognostic factor for patients with liver cancer. Patients with brain metastasis had the worst prognosis, compared with other metastasis in overall survival (OS) and cancer-specific survival (CSS) analysis. Conclusions: Different histological subtypes of liver cancer had different metastasis patterns. There were profound differences in risk of mortality among distant extrahepatic metastatic sites. Results from our studies would provide some information for follow-up strategies and future studies.

    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

    Portal biliopathy is a rare condition that is usually not diagnosed and only in few cases causes symptoms. Those symptoms are caused by vascular obstruction of the biliary tree in patients with portal hypertension. We report a case of a 29 years man who presented with history of intermittent jaundice, persistent elevation of hepatic function test and hematemesis as a manifestation of portal hypertension without liver damage. We present the clinical, radiological and pathological characteristics and literature review of the cases that had been reported, their diagnoses, treatment and clinical implication.

    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.

    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.

    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.

    The present study investigated the pathogenesis of desmoplastic stroma formation, which is characteristic of most bile duct carcinomas and other scirrhous carcinomas. Using immunohistochemical analysis, the expression of collagen types I and IV, laminin and TGF-beta1 was examined in human extrahepatic bile duct carcinoma and compared with gastric and colon carcinoma. In addition to delineating the basement membranes of carcinoma nests and blood vessels, collagen type IV was present along the thick bundles of collagenous fibers in the stroma of extrahepatic bile duct carcinoma and scirrhous gastric carcinoma. The immunoreactivity of collagen type IV was strong in the adjacent or surrounding interstitium of tumor cell nests, but was absent or weak in older, more central portions of the tumor that contained sclerotic collagen. In situ hybridization demonstrated active expression of collagen alpha1(IV) mRNA in extrahepatic bile duct carcinoma and scirrhous gastric carcinoma cells. These results suggest that, although collagen type IV is typically a component of the basement membrane, it is expressed in the interstitial stroma of extrahepatic bile duct carcinoma and scirrhous gastric carcinoma where it may play a role in desmoplastic stroma formation.

    Surgical resection is the only curative treatment for extrahepatic bile duct cancer. Additionally, the recurrence rate after curative surgery is relatively high, requiring adjuvant therapy. However, the efficacy of adjuvant chemotherapy compared with surgery alone has not yet been clarified. This study aimed to evaluate the efficacy of adjuvant chemotherapy and identify prognostic factors influencing survival in extrahepatic bile duct cancer patients who underwent curative surgical resection. Ninety-seven patients with extrahepatic bile duct cancer who underwent curative resection between January 2005 and December 2010 were retrospectively analyzed. Among the 97 patients, 31 underwent adjuvant chemotherapy and 66 did not. The 5-year overall survival rate was 34% for patients who underwent adjuvant chemotherapy. There was no significant difference for overall survival between patients who underwent adjuvant chemotherapy and those who did not (p = 0.228). On multivariate analysis, postoperative carbohydrate antigen 19-9 levels and histologic grade were independent prognostic factors related to long-term survival (p chemotherapy did not improve survival after surgical resection for extrahepatic bile duct cancer. © 2016 S.

  11. Clues to the Etiology of Bile Duct Injury in Biliary Atresia

    Science.gov (United States)

    Mack, Cara L.; Feldman, Amy G.; Sokol, Ronald J.

    2013-01-01

    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.

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

    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.

    Full Text Available Biliary atresia (BA is an orphan medical condition of the newborn, resulting in end-stage liver cirrhosis due to obliterative cholangiopathy of the extrahepatic bile duct. Although Kasai’s hepatoportoenterostomy (KPE is the well-established first-line therapy, little is known about its surgical complications. 153 patients receiving open KPE treated at a single center between 1994 and 2014 were analysed retrospectively regarding short-term complications and survival with the native liver. In brief, 40.5% of patients suffered from 1–3 surgical complications, inguinal hernias (IH being most prevalent (40.0%. In BA patients, incidence of IH was associated with male gender (p=0.002, the syndromic form of BA (p=0.038, and percutaneous drainage for ascites (p=0.002. No association was found with prematurity (p=0.074 or birth weight (p=0.912 in our study. In conclusion, IH frequently develops after open KPE of BA patients, but this complication does not negatively affect the patient’s outcome. Nevertheless, inspection of the internal inguinal ring and prophylactic closure of inapparent hernias should be discussed in order to prevent secondary surgical procedures.

    Primary biliary cholangitis (PBC) is a rare autoimmune cholestatic liver disease. It is often associated with extrahepatic autoimmune diseases. Skin disorders are sporadically reported in association with PBC. We report an unusual case of PBC associated with acquired reactive perforating dermatosis (ARPD) and present a review of the literature on skin disorders associated with PBC. Our patient presented to the dermatology department with generalized pruritus associated with nodular perforating skin lesions on the trunk, and cholestatic liver disease of unknown origin. After having established both diagnosis of ARPD and PBC, she was managed in an interdisciplinary manner, and both her skin and liver conditions improved gradually. Only one similar case is reported in the literature, in that case, the liver disease was not treated. By reviewing the literature, we found that lichen planus, vitiligo, and psoriasis are the most frequent skin disorders associated with PBC. However, there is only limited data about specific skin disorders associated with PBC. This case report of a patient with PBC associated with ARPD underlines the importance of interdisciplinary management of patients with rare liver diseases combined with rare skin disorders. The present review of the literature shows that probably, immune-mediated skin conditions are not more frequent in PBC patients than in the general population. However, the available data are scant; there is a need for high-quality data on skin conditions associated with PBC.

    Autoimmune liver diseases may be associated with extrahepatic autoimmune pathology. We report the case of a 52-year old woman who initially presented to the gastroenterology department for extreme fatigue, pale stools, dark urine and pruritus. Laboratory tests showed significant cholestasis and elevation of aminotransferase levels. Immunological tests revealed positive antinuclear (ANA=1:320) and antimitochondrial antibodies (AMA=1:40) with negative anti-smooth muscle and liver kidney microsomal type 1 antibodies. The biopsy was compatible with overlap syndrome type 1. The patient was commenced on immunosuppressive therapy according to standard of care (azathioprine 50mg, ursodeoxycholic acid and prednisone 0.5mg/kg), with moderate biochemical improvement. She subsequently developed proximal symmetrical weakness and cutaneous involvement and was diagnosed with biopsy-proven dermatomyositis. The immunosuppressive regimen was intensified to 150 mg azathioprine. At the three-month follow-up, her symptoms subsided and aminotransferases and muscle enzymes normalized. Upon further investigation the patient was diagnosed with autoimmune thyroiditis and antiphospholipid syndrome. To our knowledge, this is the first case of primary biliary cirrhosis - autoimmune hepatitis overlap syndrome associated with dermatomyositis, autoimmune thyroiditis and antiphospholipid syndrome.

    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.

    This study evaluated the outcome of salvage radiotherapy for locoregionally recurrent extrahepatic bile duct cancer. We performed a retrospective review of 23 extrahepatic bile duct cancer patients who underwent radiotherapy with or without concomitant chemotherapy for isolated locoregional recurrence after radical surgery between August 2001 and September 2013. The median disease-free interval was 11.8 months. Salvage radiotherapy was delivered to the recurrent tumour with or without initial operation bed up to a median dose of 54 Gy (range, 45-60). 18 patients received concomitant chemotherapy. The median follow-up period was 14.2 months for all patients, and 48.8 months for survivors. The median overall survival and progression-free survival (PFS) were 18.4 (range, 4.4-114.6) and 15.5 months (range, 1.6-114.6), respectively. On multivariate analysis, the use of concomitant chemotherapy was a favourable prognostic factor for PFS (p = 0.027), and prolonged disease-free interval (≥1 year) was associated with a significantly poor overall survival (p = 0.047). Grade 3 or higher toxicities did not occur in follow-up period. Salvage radiotherapy showed promising survival outcomes in locoregional recurrence of extrahepatic bile duct cancer. Our results indicated that concomitant chemotherapy was associated with improved PFS. Concurrent chemoradiotherapy can be a viable salvage treatment option in selected patients. Advances in knowledge: Locoregional recurrence is the most common pattern of failure after radical resection in extrahepatic bile duct cancer. In this study, salvage radiotherapy showed favourable survival outcomes without severe complications in locoregionally recurrent extrahepatic bile duct cancer patients.

    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.

    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).

    Full Text Available Objective To investigate the re-operation timing and surgical modality for non-anastomotic biliary stricture (NABS after orthotopic liver transplantation (OLT. Methods The clinical data of 14 NABS patients hospitalized in our center from August 2003 to April 2014 were analyzed retrospectively. The patients were treated with different modalities of re-operation according to cholangiographic results, and the outcomes of re-operation were noted by postoperative follow-up. Results Among 421 OLT patients, NABS was seen in 14 (3.3%, 14/421, and it was accompanied by stenosis of hepatic artery in 4. Their total bilirubin, ALP and r-GGT levels were significantly higher in NABS patients than in non-NABS patients (P<0.01. According to cholangiographic findings, NABS was divided into 3 types: hepatic bile duct strictures (4 patients, type Ⅰ, multiple extrahepatic and intrahepatic biliary strictures (8 patients, type Ⅱ, intrahepatic biliary stricture (2 patients, type Ⅲ. The cure rate of interventional treatment in this study was 57.1% (8/14, and 6 patients eventually required surgical treatment again. The type Ⅰ patient was treated with Roux-en-Y anastomosis, and re-transplantation for other 5 patients (type Ⅱ in 4 and type Ⅲ in 1. Among these 5 patients receiving liver re-transplantation, 1 patient died of perioperative fungal infection. The blood loss (2570±851ml and operation time (492±173min in those re-transplantation patients were almost the same as their previous-transplantation (P> 0.05. More than half of type Ⅱ and Ⅲ patients needed re-transplantation, but the probability of re-transplantation was especially higher for those with hepatic artery stenosis (75%, 3/4. Cholangitis disappeared and the total bilirubin significantly reduced from 123.4µmol/L to 31.6µmol/L after resurgery. Conclusions For those NABS patients who may fail to be improved after a minimally invasive treatment, especially when it was combined with

    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.

    Granular cell tumour of the extrahepatic biliary tract is a rare benign lesion likely of neurogenic origin. Review of the previously reported cases indicates that almost all patients are female, and the majority is Black. Symptoms usually are those of biliary obstruction or cholecystitis. Surgical resection of the tumour is curative. Intrahepatic bile duct adenoma is another rare benign biliary neoplasm that does not manifest clinically but can be confused with metastatic carcinoma, cholangio...

    Chemoradiotherapy (CHRT) is often advocated for locally-advanced biliary tract cancer (LABTC). However there was not comparative study with chemotherapy alone (CH). Patients with hilar or extrahepatic non-metastatic, LABTC could be included in this phase II trial. The inclusion criteria required World Health Organisation (WHO) performance status ⩽ 2, bilirubinemia ⩽ 50 μM/L after biliary drainage if necessary, and possibility of external radiotherapy. Fluorouracil (5 FU) infusion and cisplatin, were given in association to radiotherapy (50 Gy) in the CHRT arm. Gemcitabine+oxaliplatin (GEMOX) was planned for 6 months in the CH arm. End-points were progression-free survival (PFS), overall survival (OS), toxicity and rate of biliary complications. The trial was closed before completion due to slow recruitment. Eighteen and 16 patients were included in the CHRT and CH arms, respectively. Median follow up was 27.9 months (± 2.8). Grade III-IV toxicities were mostly haematological (23% and 25%), and gastrointestinal (11% and 6%), in the CHRT and CH arm, respectively. Biliary complications occurred in 28% of patients in the CHRT arm and 44% of patients in the CH arm (risk ratio (RR): 1.60 [0.65-3.92]). Median PFS was 5.8 months in the CHRT group and 11.0 months in the CH group (hazard ratio (HR): 0.65 [0.32-1.33]). Median OS was 13.5 months in the CHRT group and 19.9 months in the CH group (HR: 0.69 [0.31-1.55]). Combination of gemcitabine plus cisplatin seems to be at least as efficient as chemoradiotherapy (50 Gy plus 5 FU and cisplatin) in LABTC. Copyright © 2014 Elsevier Ltd. All rights reserved.

    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.

    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

    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.

    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

  20. Dexamethasone alters the hepatic inflammatory cellular profile without changes in matrix degradation during liver repair following biliary decompression.

    Biliary atresia is characterized by extrahepatic bile duct obliteration along with persistent intrahepatic portal inflammation. Steroids are standard in the treatment of cholangitis following the Kasai portoenterostomy, and were advocated for continued suppression of the ongoing immunologic attack against intrahepatic ducts. Recent reports, however, have failed to demonstrate an improved patient outcome or difference in the need for liver transplant in postoperative patients treated with a variety of steroid regimes compared with historic controls. In the wake of progressive liver disease despite biliary decompression, steroids are hypothesized to suppress inflammation and promote bile flow without any supporting data regarding their effect on the emerging cellular and molecular mechanisms of liver repair. We have previously shown in a reversible model of cholestatic injury that repair is mediated by macrophages, neutrophils, and specific matrix metalloproteinase activity (MMP8); we questioned whether steroids would alter these intrinsic mechanisms. Rats underwent biliary ductal suspension for 7 d, followed by decompression. Rats were treated with IV dexamethasone or saline at the time of decompression. Liver tissue obtained at the time of decompression or after 2 d of repair was processed for morphometric analysis, immunohistochemistry, and quantitative RT-PCR. There was a dramatic effect of dexamethasone on the inflammatory component with the initiation of repair. Immunohistochemistry revealed a reduction of both ED1+ hepatic macrophages and ED2+Kupffer cells in repair compared with saline controls. Dexamethasone treatment also reduced infiltrating neutrophils by day 2. TNF-alpha expression, increased during injury in both saline and dexamethasone groups, was markedly reduced by dexamethasone during repair (day 2) whereas IL-6, IL-10, and CINC-1 remained unchanged compared with saline controls. Dexamethasone reduced both MMP8 and TIMP1 expression by day 2

    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.

    Only a few studies have evaluated the clinicopathological significance of the p53 protein expression and s-p53-Abs level in patients with cholangiocarcinoma. We therefore analyzed the clinicopathological and prognostic significance of s-p53-Abs in patients with extrahepatic cholangiocarcinoma. We prospectively evaluated s-p53-Abs levels before and after surgery in 61 patients with extrahepatic cholangiocarcinoma to determine the relationship between clinicopathological factors and the prognostic significance of s-p53-Abs. Among a total of 61 primary extrahepatic cholangiocarcinoma cases, 23% were positive for s-p53-Abs. Combination of s-p53-Abs with the conventional serum markers carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) significantly increased the rate of positive extrahepatic cholangiocarcinoma cases (57% for CEA and/or CA19-9 vs. 75% for CEA and/or CA19-9 and/or s-p53-Abs, P = 0.035). There were no significant differences in clinicopathological factors between the p53-seropositive and p53-seronegative patients. An immunohistochemical analysis showed the presence of significant associations between the intensity (P = 0.003) and extent (P = 0.001) of p53 immunoreactivity and p53-seropositivitly. Although s-p53-Abs was not a significant prognostic factor for the survival in either univariate or multivariate analyses, p53 immunoreactivity was independently associated with a poor survival. Among patients positive for s-p53-Abs before surgery, the s-p53-Abs levels were reduced after surgery in most. These findings suggested that s-p53-Abs might be associated with p53 immunoreactivity. In addition, s-p53-Abs may be useful for a diagnosis, but was not useful for predicting tumor recurrence or the survival. This study was registered as UMIN000014530.

    To determine the heritability of extra-hepatic portosystemic shunts and elevated post-prandial serum bile acid concentrations in Maltese dogs. Maltese dogs were recruited and investigated by a variable combination of procedures including dynamic bile acid testing, rectal ammonia tolerance testing, ultrasonography, portal venography, surgical inspection or necropsy. In addition, nine test matings were carried out between affected and affected dogs, and affected and unaffected dogs. In 135 variably related Maltese, shunt status could be confirmed in 113, including 19 with an extra-hepatic portosystemic shunt (17 confirmed at surgery, 2 at necropsy). Rectal ammonia tolerance testing results and post-prandial serum bile acid concentrations were retrievable for 50 and 88 dogs, respectively. Pedigree information was available for these 135 and an additional 164 related dogs. Two consecutive test matings were carried out between two affected animals (whose shunts had been attenuated), with 2 of 8 (25%) of offspring having an extra-hepatic portosystemic shunt. Six test matings were carried out between an affected and an unaffected animal, with 2 of 22 (9%) offspring affected. Heritability of extra-hepatic portosystemic shunt was 0·61 calculated using variance components analysis [95% confidence interval (CI) 0·14 to 1·0, P=0·001]. The best fitting model from segregation analysis was a common, partially penetrant, recessive model (allele frequency 0·34, penetrance 0·99, CI 0·09 to 1·0). The heritability of elevated post-prandial serum bile acid (and thus likely portal vein hypoplasia) was 0·81 (CI 0·43 to 1·0, P=0·2) after logarithmic transformation of post-prandial serum bile acid concentrations. There is strong support for extra-hepatic portosystemic shunts and elevated post-prandial serum bile acid concentrations both being inherited conditions in Maltese. © 2013 British Small Animal Veterinary Association.

    An accurate diagnosis of the primary cancer in cases with metastatic lesions is quite important because misdiagnosis may lead to the selection of incorrect adjuvant therapy and worse long-term outcomes after surgery. The metastatic sites associated with the dissemination of colon cancer are well known and normally predictable, which includes the lymphatic, haematogenous, or peritoneal regions, while other locations are quite rare. In this report, we present a case of colon cancer with an unusual metastatic pattern mimicking an intraductal papillary neoplasm of the bile duct (IPNB) present in the extra-hepatic bile duct with a cytokeratin (CK)-7-negative and CK-20-positive profile (intestinal type). In the case of this patient who had a history of colon cancer, immunohistochemical staining for the CKs was useful for distinguishing between primary IPNB and colon cancer metastases. We suspect that the metastatic pattern of this case of colon cancer that mimicked IPNB at the extra-hepatic bile duct developed incidentally via the bile stream. This is a rare case of colon cancer metastasis mimicking IPNB at the extra-hepatic bile duct. Our findings also suggest that there may be an incidental 4th metastatic route via the bile stream.

    1998-01-01

    Full Text Available This study reports our experience of 8 cases of extrahepatic portal hypertension after 273 orthotopic liver transplantations in 244 adult patients over a 10- year period. The main clinical feature was ascites, and the life-threatening complication was variceal bleeding. Extrahepatic portal hypertension was caused by portal vein stenosis in 6 patients, and left-sided portal hypertension in 2 patients after inadventent ligation of portal venous tributaries or portasystemic shunts. All patients with portal vein stenosis had complete relief of portal hypertension after percutaneous transhepatic venoplasty (n=4 or surgical reconstruction (n=2, after a median follow-up of 33 (range: 6–62 months. Of the 2 patients with left-sided portal hypertension, one died after splenectomy and one rebled 6 months after left colectomy. This study suggests that extrahepatic portal hypertension is a series complication after liver transplantation that could be prevented by meticulous portal anastomosis and closure of portal tributaries or portasystemic shunts to improve the portal venous flow. However, any ligation has to be performed under ultrasound guidance to avoid inadventent venous ligations.

    The accurate diagnosis of extrahepatic bile duct carcinoma is difficult, even now. When ultrasonography (US) shows dilatation of the bile duct, magnetic resonance cholangiopancreatography followed by endoscopic US (EUS) is the next step. When US or EUS shows localized bile duct wall thickening, endoscopic retrograde cholangiopancreatography should be conducted with intraductal US (IDUS) and forceps biopsy. Fluorescence in situ hybridization increases the sensitivity of brush cytology with similar specificity. In patients with papillary type bile duct carcinoma, three biopsies are sufficient. In patients with nodular or infiltrating-type bile duct carcinoma, multiple biopsies are warranted, and IDUS can compensate for the limitations of biopsies. In preoperative staging, the combination of dynamic multi-detector low computed tomography (MDCT) and IDUS is useful for evaluating vascular invasion and cancer depth infiltration. However, assessment of lymph nodes metastases is difficult. In resectable cases, assessment of longitudinal cancer spread is important. The combination of IDUS and MDCT is useful for revealing submucosal cancer extension, which is common in hilar cholangiocarcinoma. To estimate the mucosal extension, which is common in extrahepatic bile duct carcinoma, the combination of IDUS and cholangioscopy is required. The utility of current peroral cholangioscopy is limited by the maneuverability of the “baby scope”. A new baby scope (10 Fr), called “SpyGlass” has potential, if the image quality can be improved. Since extrahepatic bile duct carcinoma is common in the Far East, many researchers in Japan and Korea contributed these studies, especially, in the evaluation of longitudinal cancer extension.

    Cholelithiasis is a kind of common and multiple diseases. In recent years, traditional laparotomy has been challenged by a minimally invasive surgery. Through literature review, the therapeutic method, effect, and complications of minimally invasive treatment of intrahepatic and extrahepatic bile duct stones by combining our practical experience were summarized as follows. (1) For intrahepatic bile duct stones, the operation may be selected by laparoscopic liver resection, laparoscopic common bile duct exploration (LCBDE), or percutaneous transhepatic cholangioscopy. (2) For concomitant gallstones and common bile duct stones, the surgical approach can be selected as follows: laparoscopic cholecystectomy (LC) combined with endoscopic sphincterotomy (EST) or endoscopic papillary balloon dilatation, LC plus laparoscopic transcystic common bile duct exploration, LC plus LCBDE, and T-tube drainage or primary suture. (3) For concomitant intrahepatic and extrahepatic bile duct stones, laparoscopic liver resection, choledochoscopy through the hepatic duct orifice on the hepatectomy cross section, LCBDE, EST, and percutaneous transhepatic cholangioscopic lithotripsy could be used. According to the abovementioned principle, the minimally invasive treatment approach combined with the surgical technique and equipment condition will be significant in improving the therapeutic effect and avoiding the postoperative complications or hidden dangers of intrahepatic and extrahepatic bile duct stones.

    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.).

    The liver is the solid organ most commonly injured as a result of blunt abdominal trauma. Complete avulsion of the common hepatic duct is a rare and devastating type of hepatobiliary trauma. Here the authors report the case of a 7-year-old child who had complete biliary disruption as a result of an abdominal crush injury that was not diagnosed correctly preoperatively. The intraoperative diagnosis and treatment of this injury is discussed.

    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 tr...

    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

    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.

    To evaluate the feasibility and reliability of endoscopic transpapillary bile duct biopsy for the diagnosis of biliary strictures. A total of 360 patients (241 men) who underwent endoscopic retrograde cholangiopancreatography for biliary strictures with biopsy from April 2012 to March 2016 at Tokyo Medical University Hospital were retrospectively reviewed. This study was approved by our Institutional Review Board (No. 3516). Informed consent was obtained from all individual participants included in this study. The biopsy specimens were obtained using a novel slim biopsy forceps (Radial Jaw 4P, Boston Scientific, Boston, MA, United States). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 69.6%, 100%, 100%, 59.1%, and 78.8%, respectively. The sensitivity was 75.6% in bile duct cancer, 64% in pancreatic cancer, 61.1% in gallbladder cancer, and 57.1% in metastasis. In bile duct cancer, a lower sensitivity was observed for perihilar bile duct stricture (68.7%) than for distal bile duct stricture (83.1%). In terms of the stricture lengths of pancreatic cancer, gallbladder cancer, and metastasis, a longer stenosis resulted in a better sensitivity. In particular, there was a significant difference between pancreatic cancer and gallbladder cancer (P < 0.05). One major complication was perforation of the extrahepatic bile duct with bile leakage. Endoscopic transpapillary biopsy alone using novel slim biopsy forceps is feasible and reliable, but restrictive. Biopsy should be performed in consideration of the stricture level, stricture length, and cancer type.

    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 prevalence, clinical characteristics, and outcomes of patients with antimitochondrial antibodies (AMAs), but no clinical evidence of primary biliary cholangitis (PBC), are largely unknown. A prospective study of AMA incidence was conducted through a nation-wide network of 63 French immunology laboratories. Clinical data from 720 of 1,318 AMA-positive patients identified in 1 year were collected. Patients were categorized as either newly diagnosed with PBC (n = 275), previously diagnosed with PBC (n = 216), or with nonestablished diagnosis of PBC (n = 229). The latter group was specifically evaluated. Follow-up data were collected for up to 7 years after detection of AMAs. Prevalence of AMA-positive patients without evidence of PBC was 16.1 per 100,000. These patients had the following characteristics: 78% female; median age 58 years; median AMA titer 1:160; extrahepatic autoimmune disorders 46%; normal serum alkaline phosphatases (ALP) 74%; ALP above 1.5 times the upper limit of normal 13%; and cirrhosis 6%. Compared to those newly diagnosed with PBC, the patients were slightly younger, had lower AMA titers, and lower sex-ratio imbalance. Among the patients with normal ALP and no evidence of cirrhosis, the 5-year incidence rate of PBC was 16%. Whereas no patients died from PBC, the 5-year survival rate was 75%, as compared to 90% in a control, standardized population matched for age and sex (P < 0.05). Nearly half of the newly detected AMAs in clinical practice does not lead to a diagnosis of PBC. PBC is unrecognized in 13% of those cases. Only 1 in 6 patients with AMAs and normal ALP will develop PBC after 5 years. The mortality of AMA-positive patients without PBC is increased irrespective of the risk of PBC development.

    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 GBV-C/HGV virus has clearly established transmission modes, mainly blood contamination, and occasionally sexual transmission. It is frequently found among transfused patients, intravenous drug abusers, and hemodialysis patients and often associated with HCV. Its hepatic pathogenicity is very weak, marked by a moderate and transitory cytolysis. Chronic carriage is possible, but does not lead to chronic hepatitis. Carriage can be maintained before the virus disappears. The authors report the case of a patient presenting with pleuropericarditis after a blood transfusion without any other etiology than infection by GBV-C/HGV virus. The possible extrahepatic pathogenicity of the virus is suggested. This hypothesis was rarely put forward.

    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. Although the involvement of a periductular

    Inflammation and oxidative stress are important pathways in the development of liver fibrosis following biliary obstruction. To evaluate the effects of low dose dexamethasone and chitosan, a natural compound with no side-effects, on liver damage caused by bile duct ligation in rats. Fifty female Wistar rats, randomly and equally divided in 5 groups: I (SHAM) underwent only laparotomy, II (BDL) with bile duct ligation, III (DEX) 0.125 mg/kg dexamethasone i.m. daily, IV (CS) 1 mg/kg chitosan by gavage and group V (DEX+CS), both substances. After six days, the following parameters were assessed from liver homogenates: malondialdehyde (MDA), protein carbonyls (PC), reduced glutathione (GSH), total SH groupings, nitric oxide (NO), and from plasma: MDA, γ-glutamyltranspeptidase (GGT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TB). A histopathological examination was performed using some of the elements of the Knodell Histological Activity Index. BDL significantly increases the levels of MDA, liver enzymes, and the necro-inflammatory score compared to the sham group and it decreases the antioxidant capacity. DEX protects against lipid peroxidation and improves the antioxidant capacity, but it is not able to protect the hepatocytes. Chitosan significantly decreases (pliver necrosis and inflammation (2.75±0.95 vs 1±0, p<0.05). Both CS and DEX reduce the level of NO significantly. BDL induces severe oxidative stress damage after six days already. Chitosan proved very efficient in protecting the hepatocytes against oxidative stress, a fact supported by the histological findings.

    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.

    BALB/c mice injected with seven 0.15-ml samples of whole rabbit serum over a 2-week period developed nonneoplastic proliferation of the extrahepatic bile duct epithelium and glandular components. Sera from other animals, including bovines, humans, pigs, goats, and chickens as well as non-serum-containing secretions such as human breast milk and bile also produced this effect. Partial purification utilizing gel filtration and affinity chromatography of the active 33-65% saturated ammonium sulfate precipitate of whole serum indicated that the distribution and characteristics of this glycoprotein showed some similarities with those of IgA. Chromatographically purified human IgA was administered to BALB/c mice and was found to induce bile duct proliferation identical to that seen with whole human serum. Purified human IgG and IgM had no activity. Since IgA-containing serum from BALB/c mice was inactive, it appears that heterologous IgA functions as a specific extrahepatic bile duct growth factor (BDGF) in BALB/c mice. Murine susceptibility to the growth-stimulating effect of serum was strain specific; genetic studies utilizing crosses of susceptible (BALB/c) and resistant (C57BL/10) strains of mice revealed that the ability to respond to the infusion of BDGF is inherited in a polygenic fashion.

    Full Text Available Partitioning defective 3 (Par-3, a crucial component of partitioning-defective complex proteins, controls cell polarity and contributes to cell migration and cancer cell epithelial-to-mesenchymal transition. However, the clinical relevance of Par-3 in tumor progression and metastasis has not been well elucidated. In this study, we investigated the impact and association of Par-3 expression and clinical outcomes with hepatocellular carcinoma (HCC. We first confirmed that Par-3 was abundantly expressed in HCC cell lines by Western blot analysis. We used immunohistochemistry to analyze the association of Par-3 expression and clinicopathological characteristics in primary and subsequent metastatic tumors of patients with HCC. Par-3 was overexpressed in 47 of 111 (42.3% primary tumors. Increased expression of Par-3 in primary tumors predicted an increased five-year cumulative incidence of extrahepatic metastasis. In addition, multivariate analysis revealed that Par-3 overexpression was an independent risk factor of extrahepatic metastasis. Increased Par-3 expression in primary tumors was associated with poor five-year overall survival rates and was an independent prognostic factor on Cox regression analysis. In conclusion, we show for the first time that increased Par-3 expression is associated with distant metastasis and poor survival rates in patients with HCC. Par-3 may be a novel prognostic biomarker and therapeutic target for HCC.

    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.

    We experienced ileal perforation caused by dislocated biliary endoprosthesis in 59 years old female patient. The endoprosthesis was implanted due to biliary fistula after laparoscopic cholecystectomy 2 years before the perforation. It seems that endoprosthesis dislocation and the perforation were the result of too long stay of endoprosthesis. After the surgical management and the removal of the prosthesis patient was cured. Although ileal perforation caused by dislocated biliary endoprosthesis is rare, clinicians should be aware of the possibility of its occurrence. © 2015 MEDPRESS.

    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.

    2012-01-01

    Portal biliopathy refers to biliary abnormalities secondary to extrahepatic portal vein obstruction and cavernous transformation and is caused by vascular compression from peribiliary collateral vessels, producing segmental stenoses of the common bile duct and abnormal liver function test (LFT) results. A review of imaging studies yielded 18 patients with abnormal LFT results, biliary tract dilatation, and extrahepatic portal vein obstruction with cavernous transformation. Multidetector computed tomography and magnetic resonance imaging showed biliary stenotic segments in 11 patients secondary to extrinsic compression from enlarged peribiliary collaterals. Clinical and imaging follow-up demonstrated improvement in LFT results with minimal decrease in bile duct dilatation, eliminating percutaneous or endoscopic biliary intervention.

    2017-05-01

    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.

    2013-01-01

    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.

    2014-08-01

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

    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.

    Full Text Available Extrahepatic portal vein aneurysm is a rare disorder. From 1956 to 2008, we found only 43 published English-language reports, including 67 cases, using Pub Med. We report a case of a 77-year-old woman who had complaints of lower abdominal fullness and residual urine. We performed ultrasonography (US, which demonstrated a congenital extrahepatic portal vein aneurysm. She had no obvious symptoms of the extrahepatic portal vein aneurysm. She had undergone gastrectomy without blood transfusion for gastric ulcer more than 20 years ago. Physical examination revealed no abnormal findings. US revealed a 2.2×1.8 cm, round shaped hypoechogenic lesion at the hepatic hilum. Color Doppler US showed bidirectional colors due to circular flow within this lesion. 3D-CT and CT angiography demonstrated that the saccular aneurysm at the hepatic hilum was 3.0 cm in diameter and was enhanced equal to that of portal vein.Twenty-six months after the diagnosis, the aneurysm had not grown in size. Since our patient had no serious complaints or liver disease, surgical procedures had not been employed. US and 3D-CT are noninvasive diagnostic techniques and are helpful in the diagnosis and follow-up of extrahepatic portal vein aneurysms.

    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.

    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.

    Full Text Available Abstract Background Clinicians often experience extrahepatic metastases associated with hepatocellular carcinoma (HCC, even if no evidence of intrahepatic recurrence after treatment is observed. We investigated the pretreatment predictors of extrahepatic metastases in HCC patients. Methods Patients diagnosed with HCC without evidence of extrahepatic metastases were prospectively enrolled. We evaluated the correlation between extrahepatic metastases and pretreatment clinical variables, including serum tumor markers. Results A total of 354 patients were included. Seventy-six patients (21% had extrahepatic metastases during the observation period (median, 25.3 months; range, 0.6-51.3 months. Cox regression multivariate analysis showed that serum protein induced by vitamin K absence or antagonist-II (PIVKA-II production levels, the intrahepatic tumor stage, platelet count, and portal vein thrombosis were independent risk factors for extrahepatic metastases. Patients with a PIVKA-II production ≥ 300 mAU/mL had a 2.7-fold (95% confidence interval; 1.5-4.8; P Conclusion PIVKA-II production levels might be a good candidate predictive marker for extrahepatic HCC metastases, especially in patients with smaller and/or fewer tumors in the liver with in stages regardless of serum alpha-fetoprotein.

  10. Functional diagnosis of biliary drainage endoprosthesis by hepatobiliary scintigraphy

    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.

    PurposeTo investigate the prevalence and site of origin of extrahepatic arteries originating from hepatic arteries on early phase CT during hepatic arteriography (CTHA) was accessed. Visualization of these elements on digital subtraction hepatic angiography (DSHA) was assessed using CTHA images as a gold standard.Materials and MethodsA total of 943 patients (mean age 66.9 ± 10.3 years; male/female, 619/324) underwent CTHA and DSHA. The prevalence and site of origin of extrahepatic arteries were accessed using CTHA and visualized using DSHA.ResultsIn 924 (98.0%) patients, a total of 1555 extrahepatic branches, representing eight types, were found to originate from hepatic arteries on CTHA. CTHA indicated the following extrahepatic branch prevalence rates: right gastric artery, 890 (94.4%); falciform artery, 386 (40.9%); accessory left gastric artery, 161 (17.1%); left inferior phrenic artery (IPA), 43 (4.6%); posterior superior pancreaticoduodenal artery, 33 (3.5%); dorsal pancreatic artery, 26 (2.8%); duodenal artery, 12 (1.3%); and right IPA, 4 (0.4%). In addition, 383 patients (40.6%) had at least one undetectable branch on DSHA. The sensitivity, specificity, and accuracy of visualization on DSHA were as follows: RGA, 80.0, 86.8, and 80.4%; falciform artery, 53.9, 97.7, and 80.0%; accessory LGA, 64.6, 98.6, and 92.3%; left IPA, 76.7, 99.8, and 98.7%; PSPDA, 100, 99.7, and 99.9%; dorsal pancreatic artery, 57.7, 100, and 98.8%; duodenal artery, 8.3, 99.9, and 98.7%; and right IPA, 0, 100, and 99.6%, respectively.ConclusionExtrahepatic arteries originating from hepatic arteries were frequently identified on CTHA images. These arteries were frequently overlooked on DSHA.

    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.
