    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.

    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.

    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.

    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

    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...

    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.

    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

    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

    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.

    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.

    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.

    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 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.

    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.

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

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

    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.

    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.

    Full Text Available Primary involvement of liver in tuberculosis is a rare entity. It is difficult to diagnose in absence of previous history of tuberculosis or concurrent pulmonary involvement. It is usually misdiagnosed as neoplastic liver lesion, which misdirects the treatment protocol and delays proper treatment. Here we are presenting a case of 36-year-old male patient with vague right upper quadrant abdominal pain. All the laboratory values were within normal limits. Radiological investigations were in favor of biliary cystadenoma but final diagnosis was primary focal involvement of liver in tuberculosis which was histopathologically proven to be tuberculous granulomas on biopsy of the resected mass.

    Biliary cystadenoma is a benign, but potentially malignant, cystic neoplasm of the biliary ducts occurring most commonly in middle-aged females and very rarely in children. We present a 9-year-old boy with biliary cystadenoma, diagnosed by MRI using a new liver-specific contrast agent (gadoxetic acid) that is eliminated by the biliary system. The images clearly demonstrate the communication between the multiloculated cystic mass and the biliary tree, suggesting the possibility of biliary cystadenoma. Due to the malignant potential of a cystadenoma, the lesion was resected. The resection was complete and the postoperative course was uneventful. (orig.)

    Biliary cystadenomas are rare, cystic neoplasms of the biliary ductal system that usually occur in middle-aged women. They cannot be safely differentiated from cystadenocarcinomas before operation and should always be considered for resection. Cystadenomas have a strong tendency to recur, particularly following incomplete excision, and a potential of malignant transformation. Therefore, complete resection is the therapy of choice and thorough histopathologic evaluation is imperative. A case of benign biliary cystadenoma with mesenchymal stroma is presented along with a review of the relative literature addressing the clinical presentation, histology, histogenesis, differential diagnosis, imaging features, treatment and prognosis of this interesting and rare entity.

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

    Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC) are rare biliary duct neoplasms. This study investigated reasonable management strategies of cystic neoplasms in the liver. Charts of 39 BCA/BCAC patients (9 males, 30 female; median age 53.74 ± 14.50 years) who underwent surgery from January 1999 to December 2009 were reviewed retrospectively. Cyst fluid samples of 32 BCA/BCAC patients and 40 simple hepatic cyst patients were examined for the tumor markers carbohydrate associated antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA). The most frequent symptoms were abdominal pain (N = 10), abdominal mass (N = 7), abdominal distension (N = 4), jaundice (N = 2), and fever (N = 3); the remaining patients showed no clinical symptoms. Liver resection (N = 17) or enucleation (N = 22) was performed in the 39 patients. Ultimately, 35 patients were diagnosed with intrahepatic BCA and four patients were diagnosed with BCAC. The median CA19-9 level was significantly higher in BCA/BCAC patients than in simple hepatic cyst patients. The median CEA levels in BCA/BCAC patients and controls were 6.83 ± 2.43 and 4.21 ± 2.91 mg/L, respectively. All symptoms were resolved after surgery, and only one BCAC patient showed recurrence. The incidence of intrahepatic cystic lesions was 1.7%. Increased CA19-9 levels in the cyst fluid is a helpful marker for distinguishing BCA/BCAC from common simple cysts. The presence of coarse calcifications is suggestive of BCAC. Complete surgical removal of these lesions yielded satisfying long-term outcomes with a very low recurrence rate.

    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.

    Biliary cystadenoma and cystadenocarcinoma constitute less than 5% of intrahepatic cysts originating from the bile duct. The aims of this study were to characterize the clinical and pathologic aspects of these lesions, and also to discuss the treatment and prognosis of them. We reviewed the clinical records of six patients with intrahepatic biliary cystadenoma and four patients with cystadenocarcinoma who had undergone operation from January, 1990 to January, 2006 at Hanyang University Medical Center. Biliary cystadenoma mainly affected women compared to biliary cystadenocarcinoma. Both tumor have nonspecific symptom and were usually diagnosed by computed tomography and ultrasonography. These tumors were usually large, multilocular, and cystic in appearance. The pathologic findings revealed multiple cystic masses lined with cuboidal to columnar epithelium. The nature of cystic fluid was mostly mucous type. Of 10 patients in whom the lesions were completely excised, 8 patients are alive. Surgical resection of the tumor, including a margin of surrounding normal liver parenchyma, was the only curative method. Any therapy short of complete excision leads to local recurrence and risk of malignant transformation. Complete resection of a biliary cystadenoma and radical resection of a biliary cystadenocarcinoma seems to offer a chance for long-term survival.

    AIM: To investigate preoperative differential diagnoses made between intrahepatic biliary cystadenoma and intrahepatic biliary cystadenocarcinoma. METHODS: A retrospective analysis of patient data was performed, which included 21 cases of intrahepatic biliary cystadenoma and 25 cases of intrahepatic biliary cystadenocarcinoma diagnosed between April 2003 and April 2013 at the General Hospital of PLA. Potential patients were excluded whose diagnoses were not confirmed pathologically. Basic information (including patient age and gender), clinical manifestation, duration of symptoms, serum assay results (including tumor markers and the results of liver function tests), radiological features and pathological results were collected. All patients were followed up. RESULTS: Preoperative levels of cancer antigen 125 (12.51 ± 9.31 vs 23.20 ± 21.86, P cystadenoma subgroup. There were no statistically significant differences in age or gender between the two groups, or in pre- or post-operative levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin (TBIL), and direct bilirubin (DBIL) between the two groups. However, eight of the 21 patients with cystadenoma and six of the 25 patients with cystadenocarcinoma had elevated levels of TBIL and DBIL. There were three cases in the cystadenoma subgroup and six cases in the cystadenocarcinoma subgroup with postoperative complications. CONCLUSION: Preoperative differential diagnosis relies on the integration of information, including clinical symptoms, laboratory findings and imaging results. PMID:25253963

    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.

    Liver cystadenomas are rare conditions accounting to approximately 5% of all cystic lesions. The aim of our study was to establish a new diagnostic and complex therapeutic approach. In all, 12 female patients primarily diagnosed with cystadenoma of the liver were evaluated. Enucleation of the cystadenoma was performed in six (54.5%) and liver resection in four (33.3%) patients. Due to the localization, complete enucleation or radical liver resection could not be performed in two patients. In three patients, grade III-a complications were recorded after surgery. The 30-day mortality was 0%. The length of hospitalization was 27 (7-52) days. Malignant transformation occurred in two patients with incomplete removal of the cystadenoma. In both cases, carbohydrate antigen 19-9 serum levels were elevated during the follow-up period. The first patient died 28 months after primary surgery. The second patient failed to attend any further appointments. The remaining patients are in the good conditions, with no signs of recurrence. The only possible treatment of cystadenomas is their radical surgical removal. Any other incomplete surgical treatment is insufficient and associated with a high risk of malignant transformation. For patients in whom R0 resection or complete enucleation cannot be performed for technical reasons, liver transplantation should be considered.

    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.

    To investigate the imaging features of intrahepatic biliary cystadenoma and cystadenocarcinoma on B-mode and contrast-enhanced ultrasound. The B-mode and contrast-enhanced ultrasound features of 6 intrahepatic biliary cystadenomas and 7 intrahepatic biliary cystadenocarcinomas were retrospectively analyzed, and the differences between cystadenomas and cystadenocarcinomas were compared. There were no significant differences between cystadenomas and cystadenocarcinomas in terms of patient gender, age, lesion location, size, and shape (all p > 0.05). On conventional ultrasound, biliary cystadenomas were more likely to be multilocular (6/6 for cystadenoma vs. 2/7 for cystadenocarcinoma) and cystadenocarcinomas more likely presented the features of a mural or septal nodule and a nodule diameter > 1.0 cm (0/6 for cystadenoma vs. 5/7 for cystadenocarcinoma). On contrast-enhanced ultrasound, hyper-enhancement (n = 4) or iso-enhancement (n = 2) was present in the cystic wall, septations or mural nodules of the cystadenomas during the arterial phase and the enhancement washed out to hypo-enhancement (n = 6) during the late phase. Cystadenocarcinomas also showed hyper-enhancement (n = 4) or iso-enhancement (n = 3) in the cystic wall, septations or mural nodules during the arterial phase and iso-enhancement (n = 1) or hypo-enhancement (n = 6) during the late phase. Intrahepatic biliary cystadenomas are more typically multilocular cystic lesions. A mural or septal nodule and a nodule diameter greater than 1.0 cm on conventional ultrasound are suggestive of cystadenocarcinomas. Contrast-enhanced ultrasound is helpful for depicting the vascularity of the lesions but there was no significant difference between cystadenomas and cystadenocarcinomas. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Background. Biliary cystadenomas (BCAs are rare, benign, potentially malignant cystic lesions of the liver, accounting for less than 5% of cystic liver tumours. We report the outcome following resection of biliary cystadenoma from a single tertiary centre. Methods. Data of patients who had resection of BCA between January 1993 and July 2014 were obtained from liver surgical database. Patient demographics, clinicopathological characteristics, operative data, and postoperative outcome were analysed. Results. 29 patients had surgery for BCA. Male : female ratio was 1 : 28. Clinical presentation was abdominal pain (74%, jaundice (20%, abdominal mass (14%, and deranged liver function tests (3%. Cyst characteristics included septations (48%, wall thickening (31%, wall irregularity (38%, papillary projections (10%, and mural nodule (3%. Surgical procedures included atypical liver resection (52%, left hemihepatectomy (34%, right hemihepatectomy (10%, and left lateral segmentectomy (3%. Median length of stay was 7 (IQ 6.5–8.5 days. Two patients developed postoperative bile leak. No patients had malignancy on final histology. Median follow-up was 13 (IQ 6.5–15.7 years. One patient developed delayed biliary stricture and one died of cholangiocarcinoma 11 years later. Conclusion. Biliary cystadenomas can be resected safely with significantly low morbidity. Malignant transformation and recurrence are rare. Complete surgical resection provides a cure.

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

    Intrahepatic biliary cystadenoma (IHBCA) is a rare type of liver tumor. There are no specific diagnostic methods for IHBCA, so its preoperative diagnostic rate is still fairly low. The aims of this study were to evaluate the clinical manifestations, diagnosis, and treatment of IHBCA. We retrospectively analyzed data from 14 patients treated in our hospital from January 2004 to April 2014. Eleven patients (78.6 %) were female, and the average age was 48.0 years (range 16-77 years). The most common clinical symptoms were abdominal discomfort (i.e., abdominal pain), reported in seven cases (50 %), and fullness after eating, reported in two cases (14.3 %). Jaundice was a less common symptom reported in one case (7.1 %). Four patients (28.6 %) were asymptomatic. Enhanced computed tomography (CT) scan showed multilocular or internal septations in 11 cases (78.6 %) and papillary projections or mural nodules on the cyst wall in one case (7.1 %). After injection of a contrast agent, the cyst walls or septations were slightly enhanced in nine cases (64.3 %). All 14 patients underwent surgical resection. Only one case showed recurrence (2 years postoperatively); the remaining 13 patients were recurrence-free. Intrahepatic biliary cystadenoma often occurs in middle-aged women. The main clinical symptoms are abdominal fullness with a sense of pain and jaundice. Enhanced CT is the main preoperative diagnostic method. Radical resection is the best treatment for IHBCA and can effectively prevent recurrence.

    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

    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

    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.

    Magnetic resonance imaging (MRI) and magnetic resonance cholangio-pancreatography (MRCP) features were analyzed in the diagnosis of seven surgically resected hepatobiliary cystic tumors with reference to histopathological data. Homogeneity, size, location, signal intensity, presence or absence of septa and/or nodules and MRCP features of the lesions were studied. Histological evidence demonstrated six biliary cystadenoma (BCA) including four pseudo-ovarian stroma (POS) and one biliary cystadenocarcinoma (BCAC). Cystic lesions (3-15 cm in diameter) were homogeneous in the six BCA, heterogeneous in the one BCAC, and were located in the left and right liver, respectively. On T2-weighted images all lesions were hyperintense. On T1-weighted images hypointensity was found in three BCA (all serous fluid, including one POS), isointensity was found in the three others (two mucinous and one hemorrhagic fluid, including three POS) and in the one BCAC (containing mucinous fluid). Septas were present in all cases and nodules only in the one BCAC. On MRCP a hyperintense cystic lesion was found in all cases and a bile ducts dilatation in two BCA and the one BCAC. Gadolinium-enhanced MRI in combination with MRCP is a valuable tool for the diagnosis of BCA or BCAC. However, no specific information is gained for POS detection. (orig.)

    We report two cases of biliary cystadenoma with mesenchymal stroma, in which we reached a preoperative diagnosis. There are three characteristics in imaging. First, there is no communication between the tumors and biliary ducts. Second, the wall of the tumor is smooth and septa inside the tumor result in a 'cysts-in-cyst' appearance. Third, papillary projections that are characteristic of the intraductal papillary mucinous neoplasm of the bile duct are rarely seen. We provide characteristic figures that are remarkably helpful for the preoperative diagnosis.

    To summarize the clinical experience with diagnosis and treatment of intrahepatic biliary cystadenoma (IBCA). We retrospectively analyzed the data of 10 consecutive IBCA cases treated in our department in light of the characteristics of the epidemiology, radiology, lab tests, pathology and prognostic. The patients are all female with an average age of 48.9 (16-73) years. The number of asymptomatic, slightly symptomatic and severe symptomatic patients was 4, 4 and 2, respectively. Radiological examination showed segmented cystic lesions in all the cases with an average diameter is 13.3∓4.9 cm. The incidence of segmentation, papillary or nodular hyperplasia, and calcification within the lesions was 90%, 60% and 20%, respectively. Macroscopic examination of the specimen showed compartmentation in the lesions, and microscopically, the lesions all showed lining of cubic or columnar epithelium on the inner wall with ovary-like or fibrous stroma. Complete resection of the tumor was achieved in 8 cases and partial resection was performed in 2 cases. The patients were followed up for a mean of 55.3 (12-164) months, and none of the patients with complete tumor resection showed recurrence, while both of the two patients with partial resection had postoperative recurrence. IBCA is a rare cystic lesion occurring primarily in middle-aged women. The preoperative diagnosis of this disease relies primarily on radiological evidences, and a complete resection of IBCA may prolong the patient survival.

    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.

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.

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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

    Full Text Available OBJETIVOS: Apresentar uma revisão atualizada sobre atresia das vias biliares extra-hepáticas, com ênfase em etiopatogenia, abordagens diagnósticas e terapêuticas e prognóstico. FONTES DOS DADOS: Foram selecionadas pelos sites de busca médica (MEDLINE e PubMed pesquisas relacionadas à atresia biliar, utilizando as seguintes palavras-chave: biliary atresia,etiopathogenesis, diagnosis, treatment, prognosis, children. SÍNTESE DOS DADOS A atresia das vias biliares extra-hepáticas é a principal indicação de transplante hepático na faixa etária pediátrica. Quanto à etiologia, o citomegalovírus, o reovírus e o rotavírus têm sido os agentes mais estudados como possíveis desencadeadores da obstrução imunomediada da árvore biliar. A resposta imune, especialmente o predomínio da resposta TH1 e do interferon gama, a susceptibilidade genética e as alterações do desenvolvimento embrionário da árvore biliar são aspectos que podem participar na etiopatogênese da obliteração das vias biliares extra-hepáticas. Ainda hoje, o único tratamento disponível é a portoenterostomia, cujos resultados são melhores quando realizada nos primeiros 2 meses de vida. Em relação ao prognóstico, as crianças não tratadas vão a óbito na totalidade, por complicações relacionadas à hipertensão portal e à cirrose hepática, e mesmo os casos tratados necessitam, em sua maioria, do transplante hepático. CONCLUSÃO: A atresia das vias biliares extra-hepáticas continua sendo a principal indicação de transplante hepático em crianças, e a mudança deste panorama depende de um melhor entendimento da etiopatogenia da obstrução biliar nos diferentes fenótipos da doença. Investigações futuras a respeito do papel do interferon gama e de outras citocinas são necessárias para avaliar se esses aspectos seriam potenciais alvos de intervenção terapêutica.OBJECTIVE: To provide an updated review on extrahepatic biliary atresia, focusing

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

    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.

    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.

    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.

    Full Text Available Introduction. Hepatobiliary cystadenomas are rare benign cystic tumors and have a potential for recurrence and malignant transformation. The diagnosis may be very difficult because of absence of typical imaging feature in some cases. Case Presentation. In this paper, the authors discuss a 57-year-old woman who presented a jaundice related to hepatobiliary cystadenoma. Biological and radiological examinations have led to surgery, and the diagnosis is made after a histological examination of surgical specimens. Conclusion. This observation illustrates a hepatobiliary cystadenoma revealed by jaundice. Histology examination contributed to diagnosis. The authors discussed the mechanisms of biliary obstruction and differential diagnoses through a review of the literature.

    Macrocystic serous cystadenoma is an unusual and essentially benign pancreatic tumor. Herein, we report on a 40-year-old woman diagnosed with macrocystic serous cystadenoma who presented with obstructive jaundice. A cystic lesion in the head and body of the pancreas was revealed by abdominal computed tomography. Intraoperative pancreatic cyst aspiration ruled out mucinous cystic neoplasm which has a malignant potential. The pancreatic cyst fluid cytology was basophilic amorph materials concluded as benign cystic lesion. Internal drainage was performed instead of pancreatic resection which showed good outcome. Biliary obstruction is a rare complication of serous cystadenoma. This case describes an unusual clinical presentation of macrocystic serous cystadenoma.

    The ultrasonographic findings of 49 ovarian cystadenomas were analyzed. The results were as follows. 1. The most common age group was 3rd decade and most patients (83%) belong to active reproductive period. 2. In 80% of serous cystadenoma the size of the tumor was ranged in 6-10 cm in diameter. The large tumors of 16-20 cm in diameter were mostly mucinous cystadenomas. 3. Purely cystic appearance was the most common finding (40%) of serous cystadenoma and thick linear septation with and without solid component was the most common finding (38%) of mucious cystadenoma. 4. Thick linear septation with solid component was not found in serous cystadenoma. 5. Well defined nodular projection was found in 3 cases of serous cystadenoma but not identified in mucinous cystadenoma.

    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.

    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.

    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.

    In this report, we describe a case of hitherto unreported primary retroperitoneal acinar cell cystadenoma that morphologically and immunophenotypically resembled pancreatic acinar cell cystadenoma. Pancreatic acinar cell cystadenoma is a very uncommon benign lesion characterized by acinar cell differentiation, the evidence of pancreatic exocrine enzyme production, and the absence of cellular atypia. Our case occurred in a 55-year-old woman presenting a 10-cm multilocular cystic lesion in the retroperitoneum thought to be a mucinous cystic neoplasm. At laparotomy, the cystic mass, which showed no connection with any organ, was completely resected with a clinical diagnosis of cystic lymphangioma. The diagnosis of retroperitoneal acinar cell cystadenoma was based on the recognition of morphological acinar differentiation, the immunohistochemical demonstration of the acinar marker trypsin, and the absence of cellular atypia. These peculiar features can be used in the differential diagnosis with all the other cystic lesions of the retroperitoneum. Copyright © 2012 Elsevier Inc. All rights reserved.

    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

    We report a rare case of pancreatic serous cystadenoma, which shrank remarkably from 6 to 1.5 cm in diameter, with cystic degeneration, over a period of only 3 weeks. A 29-year-old woman who presented with epigastric pain and jaundice underwent computed tomography, which showed a 6-cm monolocular cystic tumor in the pancreatic head. Endoscopic retrograde cholangiopancreatography showed stenosis and deviation of the inferior part of the extrahepatic bile duct. We performed surgery 3 weeks later for suspected mucinous cystadenoma or macroscopic serous cystadenoma of the pancreas. At laparotomy, the tumor in the pancreatic head was found to have shrunk remarkably. We excised the tumor completely by performing the Whipple procedure. Macroscopically, the mass was a 1.5-cm monolocular cyst. Microscopically, the cystic tumor was composed of a thick fibrous wall with granulation tissue and hemorrhage. Although epithelial cells were not found inside the cystic wall, numerous grossly invisible microcysts with glycogen-containing epithelial cells were seen at its periphery. Based on these findings, the tumor was diagnosed as a serous cystadenoma with cystic degeneration.

    Full Text Available Primary tumors of the seminal vesicle are extremely rare. Among them, there is a spectrum of tumors derived from both epithelium and stroma and so classified as epithelial-stromal tumors. Herein, we report a case of a cystadenoma in a 49-year-old asymptomatic man, detected in a routine ultrasonography for liver disease follow-up. The digital rectal examination detected a large mass anterior to rectum and posterior to bladder. Computed tomography scan and magnetic resonance imaging showed a normal prostate and a 9.0 cm cystic tumor, replacing the left seminal vesicle. The gross appearance and microscopic aspect was compatible with cystadenoma of seminal vesicle. Patient's postoperative recovery was uneventful. He is currently alive, 3 years after the diagnosis, with no signs of recurrence.

    Hepatic (biliary) cystic tumor (HBCT) is a rare focal cystic liver lesion, which has been rarely described in the literature. In our current multicenter, retrospective study, we aimed to analyze contrast enhanced ultrasound (CEUS) features and its diagnostic performance in histologically proved HBCT. Twenty-three patients with single HBCT were retrospectively analyzed. Histologically, 17 (73.9%) were benign hepatic (biliary) cystadenoma (HBCA), 6 (26.1%) were hepatic (biliary) cystadenocarcinoma (HBCAC). All CEUS examinations were assessed by two independent radiologists in consensus. Criteria of CEUS imaging evaluation included the contrast enhancement pattern of lesion (hypoenhancing, hyperenhancing, isoenhancing in comparison to the surrounding liver parenchyma) during the arterial, portal venous and late phases. After injection of ultrasound contrast agents, most of the HBCTs (78.3%, 18/23) had typical honeycomb enhancement pattern of the cystic wall, septa or mural nodules. Comparing between HBCA and HBCAC, hyperenhancement of the honeycomb septa during the arterial phase was more common in HBCA (p = .047). However, hypoenhancement during the portal venous and late phases was the characteristic of HBCAC (p = .041). The EFSUMB algorithm for CEUS for characterization of solid focal liver lesions is also applicable to HBCT. CEUS evaluation can avoid further diagnostic investigations or invasive biopsy procedure.

    Hepatobiliary cystadenoma is a rare hepatic neoplasm that has been reported only 10 times in the pediatric population. Although considered a benign cystic tumor of the liver, hepatobiliary cystadenoma has a high risk of recurrence with incomplete excision and a potential risk for malignant degeneration. Complete tumor excision with negative margins is the mainstay in treatment. Unfortunately, due to the paucity of cases and its vague presentation, hepatobiliary cystadenoma is rarely diagnosed preoperatively. Therefore, in patients with hepatic cystic masses without a clear diagnosis, total resection of the lesion with negative margins is indicated to adequately evaluate for malignant potential and limit the risk of recurrence. We describe a 2-year-old girl with an asymptomatic abdominal mass that was found to be hepatobiliary cystadenoma. In addition, the pathogenic, histopathologic and clinical features of hepatobiliary cystadenoma are reviewed.

    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.

    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.

    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...

    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.

    Primary tumors of the seminal vesicles are extremely rare. There have been 25 reports of this tumor from overseas and most cases are cystadenoma. We report a case of seminal vesicle cystadenoma in a 70-year-old man who presented with lower abdominal pain and urinary frequency. A digital rectal examination detected a projecting and hard mass in the right side of the prostate. Magnetic resonance imaging (MRI) showed a 15 cm multiple cystic mass continuous with the right seminal vesicle. A transrectal needle biopsy revealed benign tissue. The tumor was resected using an open transvesical approach that enabled full exposure of the seminal vesicle without damaging the nerves and blood supply of the bladder. Pathology was consistent with a benign seminal vesicle cystadenoma. We describe the natural history, pathology,and surgical approach in this case.

    Primary retroperitoneal mucinous cystic tumors are extremely rare. These tumors can be classified as a primary retroperitoneal mucinous cystadenoma with or without borderline malignancy or primary retroperitoneal mucinous cystadenocarcinoma. The most common of these is primary retroperitoneal mucinous cystadenoma, which almost always occurs in female patients; only ten cases have been reported in males. The most common clinical findings for this tumor type include nonspecific abdominal pain and a palpable abdominal mass. A definitive diagnosis is usually obtained from histopathology after surgical excision. Here, we report the case of a 60-year-old female patient who complained of abdominal pain that had been present for 3 mo and presented with a palpable abdominal mass. Multidetector computed tomography scanning revealed a large, unilocular cystic mass in the left retroperitoneal space. Surgical intervention was performed and the tumor was completely removed. Histopathologic examination confirmed that the tumor was a primary retroperitoneal mucinous cystadenoma. Two years after surgery, the patient remains disease free.

    Tumors of the appendix are extremely rare and constitute about 0.4% of all tumors of the gastrointestinal tract. The most common benign neoplasm is mucinous cystadenoma, which can be found in 0.6% of all excised appendices and it rarely produces any symptoms. We present the case of a female patient who underwent surgery in the Department of Surgery due to suspicion of an appendicular abscess. On the postoperative pathology study, the diagnosis of a tumor of the appendix (mucinous cystadenoma) was made. Mucinous cystadenoma is rarely included in the differential diagnosis of a non-specific abdominal pain accompanied by non-characteristic laboratory test results and imaging studies. There are no unequivocal guidelines and algorithms of managing this disease. Long-term prognosis is good in the case of a benign tumor.

    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.

    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.

    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.

    1999-02-16

    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.

    2017-06-01

    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.

Most patients with portal biliopathy remain asymptomatic, but approximately 10% of them advance to symptomatic abdominal pain, jaundice, and fever. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography are currently used as diagnostic tools because they are noninvasive and can be used to assess the regularity, length, and degree of bile duct narrowing. Management of portal biliopathy is aimed at biliary decompression and reducing the portal pressure. Portal biliopathy has rarely been reported in Korea. We present a symptomatic case of portal biliopathy that was complicated by cholangitis and successfully treated with biliary endoscopic procedures.

    Biliary 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.

    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.

    2008-02-01

    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.

    Mixed mucinous cystadenoma with serous cystadenoma of the pancreas is rare. There have been only two previous case reports in the English-language literature. We present a case of a 46-year-old woman who was diagnosed with mixed mucinous cystadenoma with serous cystadenoma of the pancreas. Computed tomography and magnetic resonance imaging showed a cystic neoplasm in the dorsal/proximal body of the pancreas with a clear-margin multilocular cavity and enhanced internal septum. The patient underwent laparoscopic central pancreatectomy. The diagnosis of mixed mucinous cystadenoma with serous cystadenoma of the pancreas was confirmed by pathological examination. The patient was followed up for 3 months and there were no signs of recurrence, or pancreatic exocrine or endocrine insufficiency. To the best of our knowledge, this is the first reported case treated by laparoscopic central pancreatectomy.

    Hepatobiliary cystadenoma is an uncommon lesion that is most often found in middle-aged women and difficult to diagnose preoperatively. Here, we report a case of giant hepatobiliary cystadenoma in a male patient with obvious convex papillate. On the basis of imaging examinations, the patient was diagnosed as hepatobiliary cystadenoma prior to operation. Left hepatectomy was performed and the patient was symptom-free during a 6-mo follow-up period, suggesting that imaging examination is the major diagnostic method of hepatobiliary cystadenoma, and operation is its best treatment modality.

    Freezing strips of ovarian cortex before chemotherapy followed by transplantation is an experimental method to preserve fertility for reproductive-aged women with cancer. We report a case of a cancer patient who developed a mucinous cystadenoma in a grafted piece of ovarian cortex. A 32-year-old woman with a Ewing sarcoma had ovarian cryopreservation using cortical strip freezing before receiving chemotherapy. Five years later she had no ovarian function, and the strips were thawed and grafted back onto the ovary. She spontaneously became pregnant 1 year after this procedure and delivered a healthy neonate near term. During the cesarean delivery, a 5×3-cm cyst was removed from the graft. On pathologic evaluation, it was determined to be a mucinous cystadenoma. Ovarian pathology can develop in previously frozen ovarian cortex tissue after transplantation back onto the ovary. This suggests that routine gynecologic surveillance remains important for these women.

    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.

  6. Influence of distal ileum exclusion on hepatic and renal functions in presence of extrahepatic cholestasis

    Evandro Luis de Oliveira Costa

    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.

    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.

    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.

    Multilocular prostatic cystadenoma is a rare benign neoplasm located between the bladder and the rectum. These are prostatic tissue and have been shown to harbor high-grade intraepithelial neoplasia and likely susceptible to the same disease processes seen in the prostate gland. We report the first case of conventional prostatic adenocarcinoma involving a multilocular cystadenoma. Distinction from cystadenocarcinoma is also made.

    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.

    Ten cases of cystadenoma or cystadenocarcinoma of the pancreas were examined by computed tomography (CT). All but one showed characteristic findings consisting of both cystic and solid components. Innumerable small cysts producing a honeycomb appearance were noticed in serous cystadenomas. A well-defined multilocular cystic mass containing thin, straight, and/or curvilinear septa or a unilocular cystic tumor with a papillary projection and locally thickened wall was present in mucinous cystadenomas. The CT findings in cystadenocarcinomas varied depending on the relative size of the cystic and solid portions and the grade of malignancy. CT was useful in detecting and diagnosing cystic neoplasms of the pancreas and differentiating benign serous cystadenomas from potentially malignant cystadenomas in typical cases. However, aspiration biopsy is recommended when findings are equivocal.

    We describe a 13-year-old girl who underwent insertion of a Flexima biliary stent for obstructive jaundice due to compression of the extrahepatic bile duct by an enlarged lymph node secondary to neuroblastoma. This novel endoscopic internal biliary drainage procedure was safe and effective even for a child, and improved her quality of life. We further review other treatment options available for malignant obstructive jaundice in children. (orig.)

    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.

    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.

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.

    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

    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.)

    Pancreatic heterotopias (HP) are rare. They can occur at any age with a slight male predominance. These lesions are usually asymptomatic and they are often found incidentally during upper or lower GI endoscopy or during the anatomo-pathological examination of an organ which was resected for other reasons; they can be isolated or associated with a digestive pathology. We report, through observation, the association of HP with serous cystadenoma of the pancreas discovered during examinations to identify the etiology of isolated abdominal pain. The aim of this study is to analyse clinical and histological features of this rare pathology.

    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 recently experienced a 43-year-old man with a large, multiloculated, cystic tumor that appeared on the pelvis. The tumor was composed of glands and cysts lined by prostatic-type epithelium and attached microscopically to the prostate by a pedicle. The prostatic nature of the lesions was confirmed by immunohistochemical staining of epithelium for prostate specific antigen (PSA). Our review of literature disclosed nine similar cases in men of various ages, originated from the prostate and grew to massive proportions. The lesions in these reported cases did not invade contiguous structures but they can adhere to viscera in their proximity. The multilocular prostatic cystadenoma is a pathologically benign entity, and they can be definitively treated by a carefully planned complete surgical excision. This lesion should be included in the differential diagnosis of retroperitoneal cystic tumors in man. We report a rare case of multilocular prostatic cystadenoma that did not invade adjacent organs and showed no evidence of recurrence after complete surgical excision. PMID:9811190

    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.

  8. ETIOLOGY, PATHOGENESIS AND MORPHOLOGY OF BILIARY ATRESIA

    Directory of Open Access Journals (Sweden)

    O. E. Iryshkin

    2012-01-01

    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.

    During a 4-year period 17 patients with pancreatic apudoma and 3 patients with cystadenoma of the pancreas were admitted to this hospital. Computed tomography correctly located 3 of 4 insulinomas examined, while angiography revealed 4 of 8, which indicates that CT may replace angiography as the primary examination of these tumors, and possibly also other types of apudomas. When CT fails angiography may demonstrate a pancreatic tumor, suggesting angiography as a supplementary examination. In cystadenoma sufficient information was obtained at CT.

    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.

    A 52-yr-old man presented with severe obstructive urinary symptoms. Ten years earlier, a digital rectal examination disclosed a small mass above the prostate, and a computed tomography (CT) scan showed a 3.5-cm cystic tumor of the right seminal vesicle. He had been followed conservatively elsewhere. Reevaluation of the mass with a CT scan and magnetic resonance imaging showed that the mass had grown to a maximal diameter of 14 cm. A transabdominal needle biopsy revealed benign fibromuscular tissue. The tumor was then resected by an open transvesical approach. Pathology was consistent with a benign seminal vesicle cystadenoma. The natural history, pathology, and surgical approach are described. Copyright © 2009 European Association of Urology. Published by Elsevier B.V. All rights reserved.

    Solitary pancreatic involvement of tuberculosis is rare, especially in an immunocompetent individual, and it may be misdiagnosed as pancreatic cystic neoplasms. Pancreatic cystic neoplasms are being identified in increasing numbers, probably because of the frequent use of radiology and advances in endoscopic techniques. However, they are composed of a variety of neoplasms with a wide range of malignant potential, and it is often difficult to differentiate pancreatic tuberculosis mimicking cystic neoplasms from benign or malignant pancreatic cystic neoplasms. Non-surgical diagnosis of pancreatic tuberculosis is inconclusive and continues to be a challenge in many cases. If so, then laparotomy should be employed to establish the diagnosis. Therefore, pancreatic tuberculosis should be kept in mind during the differential diagnosis of solitary cystic masses in the pancreas. We report a patient who had solitary pancreatic tuberculosis masquerading as pancreatic serous cystadenoma. PMID:19248204

    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.

    Hepatobiliary cystadenoma and cystadenocarcinoma are rare cystic lesions of the liver. The aim of the study was to discuss the clinical features, diagnostic methods and surgical treatment of hepatobiliary cystadenoma and cystadenocarcinoma in our hospital. Six patients with hepatobiliary cystadenomas and four with hepatobiliary cystadenocarcinomas were evaluated. We collected detailed clinical data, and all patients were followed. Three patients of the 6 with cystadenomas and 2 patients of the 4 with cystadenocarcinomas had marked elevation of CA19-9 (average, 707.0 U/ml and 1078.5 U/ml, respectively). CT scan with contrast revealed typical lesions in all 10 cases, i.e., cyst-occupying lesions with separations in the liver. All patients with hepatobiliary cystadenoma were treated by partial hepatectomy. None of them recurred at a mean follow-up of 40 months. Three patients with hepatobiliary cystadenocarcinoma underwent hepatectomy, without recurrence or metastasis at a mean follow-up of 32 months. Tumor markers (CA19-9) and imaging findings may be helpful for an early diagnosis. Complete resection is still the best choice. Even for hepatobiliary cystadenocarcinoma, considering the low malignant grade, we suggest that for the best prognosis radical excision should be attempted.

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

    The topic of child sex trafficking is receiving increased attention both in the lay press and in research articles. Recently, a number of physician organizations have issued policy statements calling for the education and involvement of physicians in combating this form of "modern-day slavery." Primary care and emergency medicine physicians have led these efforts, but a number of these victims may present to surgeons. Surgeons are in a unique position to identify trafficked patients; during the process of undraping, intubation, and surgical preparation, signs of trafficking such as tattoos, scars, dental injuries, and bruising may be evident. In addition, these patients may have specific needs in terms of anesthesia and postoperative care due to substance abuse. Here, we report the case of an 18-year-old girl with a history of sexual exploitation who presents for cystadenoma excision. To our knowledge, this is the first report of a sex-trafficked pediatric patient presenting for surgery. Copyright © 2016 by the American Academy of Pediatrics.

    Testicular mucinous cystadenomas are rare in urological practice, and their histogenesis, course and management are debated. We report a primary testicular mucinous cystadenoma in a 54-year old male who presented with left testicular swelling and pain. He denied having a history of cryptorchidism, testicular trauma, infections, urinary complaints, or febrile illnesses. He did not have diabetes, but was on treatment for hypertension. The patient underwent a left inguinal radical orchiectomy, and histological examination of the resected tumour confirmed a primary testicular mucinous cystadenoma. The patient had an uneventful recovery, and is being followed up. Conclusively, urologists need to maintain a high index of suspicion of these tumours and their differentiation from metastatic tumours to ensure optimal therapeutic outcomes.

    Abstract Background: Appendiceal mucinous cystadenoma can present in various ways, and it is most commonly encountered incidentally during appendectomy, but mechanical intestinal obstruction secondary to an appendiceal mucocele has been rarely reported. Methods: We report a case of mechanical intestinal obstruction secondary to appendiceal mucinous cystadenoma. After nasogastric decompression and initial aggressive intravenous fluid resuscitation, an emergency operation was performed under the diagnosis of acute mechanical intestinal obstruction. Results: We performed an appendectomy and intraoperative enteral decompression without anastomoses. The pathologic examination (PE) revealed appendiceal mucinous cystadenoma. After the operation, the patient's recovery went smoothly, and the patient was discharged on the fifth postoperative day. No tumor recurrence was recorded over an 8 month follow-up period. Conclusion: Early operative intervention should be recommended to the patient with acute mechanical complete intestinal obstruction, especially the patient who had no previous abdominal surgery. And it is vital to discriminate benign and malignantappendiceal mucocel in determining the extent of surgery. PMID:28151903

    We report what to our knowledge is the first case of a giant multicystic cystadenoma of the Cowper's glands. An otherwise healthy 41-year-old man presented with acute urinary retention. Physical examination showed a perineal mass. Different imaging techniques demonstrated a multicystic tumor and en bloc excision was performed. Histological evaluation showed that the tumor arised from the bulbourethral glands; immunohistochemistry proved positive staining for high molecular weight cytokeratin. CASE HYPOTHESIS: Cystic tumors in the pelvis can arise from different structures. Malignancy should be ruled out. Surgical excision can be diagnostic and curative. Future implications: When evaluating a pelvic cystic tumor, Cowper's glands cystadenoma may be a differential diagnosis and must be considered. Similar to prostate cystadenomas, en bloc excision is the optimal treatment.

    1978-06-01

    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.

    Mucinous cystadenomas (MCAs) are benign epithelial ovarian tumors that occur rarely in children and adolescents. Because children and adolescents typically have their childbearing years ahead of them, conservative therapy is indicated. However, there is concern that ovarian cystectomy might be associated with significant recurrence risk in patients with MCA. Furthermore, guanine nucleotide binding protein, alpha stimulating (GNAS) gene mutations are associated with McCune-Albright syndrome, which is associated with cystic ovaries. We sought to evaluate the outcomes of children and adolescents with MCA treated conservatively. A subset of patients underwent GNAS gene testing. After institutional board review approval, the pathology database of a large urban children's hospital was queried to identify adolescents with MCA between the years 2008 and 2014. Fourteen patients, aged 8-18 years (median, 14), were identified. A buccal swab for genetic testing was obtained from a subset of consenting patients. MCA recurrence; ovarian return to normal size; GNAS gene variants. Two patients underwent oophorectomies, and the remaining 12 underwent cystectomies. Follow-up ultrasound examination revealed slow return of ovary to normal size. Of the 10 patients with available follow-up data, there were no recurrences at a median of 225 days from surgery. Four patients consented to a buccal swab for genetic testing, and the GNAS gene was noted to have rare variants in 2 patients. This series supports the use of ovary-sparing surgery in the treatment of MCA. Further research exploring possible genetic variants such as the GNAS gene in children and adolescents diagnosed with MCA is warranted.

    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

    Mucinous cystadenoma is a rare benign neoplasm and is usually discovered incidentally. Pleuritis and pericarditis, inflammation of the pleura and pericardium, may represent manifestations of autoimmune disorders especially in female subjects. We report a patient with polyserositis that was resolved after removal of the mucinous cystadenoma. To the best of our knowledge, this is a first report describing pleuritis and pericarditis as an initial presentation of mucinous cystadenoma of an appendix. A forty-year-old Caucasian female patient with a history of pleuritis and recurrent pericarditis was admitted to the hospital due to acute abdomen. At that time she was taking indomethacin and colchicine due to pericarditis that was controlled only with the combination of these two drugs. The patient had elevated erythrocyte sedimentation rate (ESR), increased C-reactive protein (CRP) and normocytic anemia. Immunological tests, including antinuclear antibody, anti-neutrophil cytoplasmic antibody, rheumatoid factor, and anti-cyclic citrullinated peptide antibodies, were repeatedly negative. Emergency surgery revealed acute appendicitis with perforation and subsequent diffuse peritonitis. Histopathological examination showed acute appendicitis and mucinous cystadenoma. Following the surgery the patient did not take any drugs. Fourteen months later the patient was symptom free. Pleuritis and pericarditis in female patients are most often associated with autoimmune diseases. We assume that increased ESR and CRP with anemia detected in the patient may reflect the altered immunity that is due to mucinous cystadenoma. We believe that this report has a broader clinical impact, implying that benign tumor could alter immunity, which can lead to unusual presentation such as polyserositis.

    Full Text Available Abstract Introduction While biliary cystadenoma and biliary cystadenocarcinoma involving the liver are not uncommon, biliary cystadenocarcinoma of the gall bladder is an extremely rare lesion and can be very difficult to diagnose. Case presentation A 50-year-old Indian woman presented with pain and swelling in the right hypochondrium. An ultrasonography revealed a cystic lesion arising from the gallbladder fossa. This lesion was initially managed with aspiration and antibiotics by the treating physician. The patient was referred for surgical management because the abscess was not resolved through conservative treatment. A diagnosis of an infected nonparasitic cyst was made and deroofing of the cyst was performed. A histopathological examination of the excised cyst wall showed cystadenocarcinoma. The patient subsequently underwent a successful surgical excision of the lesion. Conclusion Infective lesions of the liver are common in developing countries and are usually managed through aspiration and antibiotics. Cystadenocarcinoma of the gallbladder needs to be considered in the differential diagnosis of cystic lesions arising from the gallbladder fossa. A high index of suspicion and cytological examination from the wall of such complex lesions will help in the timely management of such lesions.

    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.

    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.

    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.

    Cystic lesions of the pancreas are relatively rare entities but have been increasingly diagnosed in recent years due to advanced imaging techniques. This category encompasses pancreatic pseudocyst as well as a wide range of pancreatic tumors with benign behavior, borderline or primary malignant. Serous cystadenoma of the pancreas represents the most common benign pancreatic tumor, with a very low but well recognized malignant potential. The clinical presentation varies according to its size; small tumors may be asymptomatic and discovered incidentally, while large tumors are more likely symptomatic. We report the case of a female patient presenting with non-specific left abdominal pain, who was diagnosed through a CT scan with a caudal pancreatic tumor. The patient underwent spleen-preserving distal pancreatectomy. The result of the histopathological examination revealed a serous cystadenoma.

    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.

    A 53-year-old woman presented with an apocrine cystadenoma of the right upper eyelid. Histologic examination revealed proliferating epithelial cells with apocrine snouts and occasional mitotic figures. Immunohistochemical analysis revealed a Ki-67 index of 15% and positive staining for synaptophysin, chromogranin, estrogen receptor, progesterone receptor, gross cystic disease fluid protein (GCDFP)-15, and mammoglobin. The complement of positive immunomarkers in this case reinforces the importance of total excision and careful histologic assessment.

    Tumors of the seminal vesicle are rare. Malignant tumors are more common than benign tumors. A seminal vesicle cystadenoma is a rarity. We report on a 41-year-old man with the incidental finding of an asymptomatic retrovesical tumor. The tumor, the seminal vesicle, and the abdominal part of the ductus deferens were surgically removed. The operative access is variable and surgical treatment is the method of choice. The patient's prognosis is good and there are no signs of recurrence.

    Cystadenoma, a common benign tumor derived from glandular tissue, generally occurs in the appendix, ovaries, kidney, or pancreas. While rare in the oral and maxillofacial region, they do sometimes occur in the parotid or minor salivary glands. We report a case of cystadenoma arising in the upper lip region. The patient was a 37-year-old woman referred to our hospital with a painless mass on the left upper lip initially found during treatment at a local dental clinic. The medical history was non-contributory. The 7×5-mm mass was well-defined, elastic, and flexible. The surface of the mucosa appeared healthy. The mass was clinically diagnosed as a benign tumor of the left upper lip. Because the tumor was painless and slow-growing, and magnetic resonance imaging suggested that it was benign, resection was performed under local anesthesia without biopsy. Histopathologically, cystadenoma was diagnosed. No signs of recurrence or metastasis have been seen as of 24 months postoperatively and the progress of the patient has been satisfactory.

    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.

    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.

    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.

    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.

    Serous cystadenomas of the pancreas are generally considered to be microcystic adenomas. Typical serous cystadenomas of the pancreas are encapsulated tumors composed of tiny cysts less than 2 cm in size showing sponge-like appearance with a central stellate scar or calcification on the cross-section. It has been recently reported, however, that serous cystadenomas may have macrocystic variants (major cysts more than 2 cm in size) that are radiologically indistinguishable from mucinous cystadenomas of the pancreas. We report the CT and MR imagings findings in a patient with mixed microcystic and macrocystic serous cystadenoma of the pancreas, indicating the histopathologic correlation. The mass was composed of two different types of cyst: multiple, small (< 2 cm) with central calcification; and large ( > 2cm) with peripheral calcification.

    Among 31 benign cystic neoplasms of the pancreas diagnosed as mucinous cystadenomas, we identified 9 (29%) cases of nonmucinous cystadenomas with a pancreatobiliary phenotype and an ovarian-like stroma. Although both cystic tumors belong to the same family, they should be separated because their epithelial lining and cyst fluid are different. The lining cells of the nonmucinous cystadenomas consisted of a single layer of cuboidal cells, similar to the epithelial cells of the normal pancreatic ducts, and were not dysplastic (90%-100% of the lining cells). The cyst fluid was described as serous or clear. The remaining 22 classical mucinous cystadenomas, lined predominantly by mucinous and foveolar epithelium, revealed focal pancreatobiliary epithelium in 86% of the cases, and 6 pancreatic invasive mucinous cystadenocarcinomas failed to show pancreatobiliary differentiation. We believe that these nonmucinous cystadenomas of the pancreas represent a distinctive subset of cystic neoplasms of the pancreas that probably have no malignant potential.

    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.

    Full Text Available Torsion of the vermiform appendix is a rare disorder, which causes abdominal symptoms indistinguishable from acute appendicitis. We report a case (a 34-year-old male of secondary torsion of the vermiform appendix with mucinous cystadenoma. This case was characterized by mild inflammatory responses, pentazocine-resistant abdominal pain, and appendiceal tumor, which was not enhanced by the contrast medium on computed tomography presumably because of reduced blood flow by the torsion. These findings may be helpful for the preoperative diagnosis of secondary appendiceal torsion.

    Full Text Available Mucocele of appendix is uncommon cystic lesion characterized by distension of the appendiceal lumen with mucus. Most of them are caused by mucinous cystadenomas and rarely cystadenocarcinomas. Clinical presentation is varied with more than half being asymptomatic. We report such a case where initial clinical findings and investigations suggested an ovarian cyst, and the diagnosis was only made at the time of surgery. In women presenting with a right iliac fossa mass and clinical features not indicative of gynaecological pathology, an appendiceal origin should be considered in the differential diagnosis.

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

    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.

  18. A case of suboccipital lump with a rare and unexpected diagnosis of apocrine cystadenoma.

    2016-01-01

    Cystadenoma of apocrine origin is a tumour of the sweat gland that is benign in nature. Classification of this pathology is based upon histological characteristics plus histochemical analysis. Prevalence of cystadenoma has been suggested to be quite rare, in the region of 1 in 1000 of subcutaneous biopsies observed. We present a case of a 40 year old man referred by his GP with a suboccipital lump, present for some years. On examination the lump was approximately 4-5cm in diameter and an unusual punctum was present. The patient proceeded to an excision of the lesion and the gross specimen showed characteristics of a multiloculated cyst, measuring some 5cm×3.5cm. Histopathology of the tumour revealed an apocrine cystadenoma; there were no features suggestive of malignancy. Previous classification of cystadenoma via histological and immunohistochemical method; has revealed only two distinct entities and the term hydrocystoma was often used in place of cystadenoma. More recent studies have suggested that a third type can be identified via immunohistochemical analysis. This third type; apocrine hydrocystoma, reveals that those previously defined as eccrine in origin may also be related to the apocrine ducts. Apocrine cystadenoma remains a benign pathology and treatment should be focussed on excision, without need for further intervention. Apocrine cystadenoma remains a relatively rare pathology, though one which should not recur if adequate treatment is given. Crown Copyright © 2015. Published by Elsevier Ltd. All rights reserved.

    The aim of this study was to compare the immunoexpression of epithelial mucins (MUCs) in salivary duct cysts, papillary cystadenomas, and mucoepidermoid carcinomas and to evaluate if any of these markers could be useful for differentiating between mucoepidermoid carcinoma and papillary cystadenoma. We also sought to validate the p63 expression pattern found to differentiate between mucoepidermoid carcinoma and papillary cystadenoma. Immunoexpression of MUC1, MUC2, MUC4, MUC7, and p63 was studied and quantified in 22 mucoepidermoid carcinomas, 12 papillary cystadenomas, and 3 salivary duct cysts. The immunohistochemical evaluation was collectively performed by 3 oral pathologists. Scores and trends in proportions were assessed using the nonparametric Wilcoxon-Mann-Whitney rank sum test. Mucoepidermoid carcinomas, papillary cystadenomas, and salivary duct cysts demonstrated variable MUC expression patterns. All tumors were positive for p63 immunoexpression with p63 labeling in salivary duct cysts and papillary cystadenomas (15/15) limited to the basal layers of the cystic spaces, whereas in mucoepidermoid carcinomas (22/22) the p63 labeling extended throughout the suprabasal layers (p cystadenoma and low-grade mucoepidermoid carcinoma. Although positive reactivity in a tumor with MUC1 and MUC4 was inconclusive, negative reactivity suggests the diagnosis of a benign PC or SDC.

    Full Text Available Mucinous cystadenoma of the testis is a very rare tumor. Herein, we report a case of mucinous cystadenoma arising in the testis of a 61-year-old man, along with a literature review. Computed tomography showed a 2.5-cm-sized poorly enhancing cystic mass. Grossly, the tumor was a unilocular cystic mass filled with mucinous material and confined to the testicular parenchyma. Histologically, the cyst had a fibrotic wall lined by mucinous columnar epithelium without atypia. Immunohistochemical staining was positive for cytokeratin 20 and CDX2, as well as focally positive for cytokeratin 7. The pathologic diagnosis was mucinous cystadenoma.

    2015-01-01

    Abstract Hepatobiliary cystadenoma complication with congenital choledochal cyst is extremely rare and has never been reported in literatures so far. The aim of the study was to investigate the disease arrangements by analyzing the case and performing a systematic review of the literature. This case report documents the details and clear patterns of the patient. A 65-year-old woman with fever (39.2°C), nausea, vomiting, and chronic hepatitis B imaging demonstrated a left hepatic multilocular cystic mass and cystic dilated common bile duct. A regular left hemihepatectomy was performed with resection of the entire tumor and choledochal cyst. The surgical margins were negative and a final diagnosis of hepatobiliary cystadenoma complicated with congenital choledochal cyst was established. The patient had an uneventful postoperative recovery and liver function returned to normal levels. Main lessons learned from this case are: the awareness should be raised about the disease to avoid misdiagnosis; preoperative ultrasonography, computed tomography, magnetic resonance imaging, and magnetic resonance cholangiopancreatography play an important role in detecting the lesion; the scope and timing of the surgery should be determined, which provide the chance of cure to complete resection of the tumor.

    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.

    Both mucinous cystadenoma of the appendix and intestinal schistosomiasis are rare lesions. We report a rare case of simultaneous giant mucinous cystadenoma of the appendix and intestinal schistosomiasis. A 64-year-old man from China presented with a one-year history of pain in the right lower quadrant of the abdomen. There were no other pertinent historical findings, other than schistosomiasis. Imaging showed a large, tubular, mesenteric cystic structure extending downwards from the inferior wall of the cecum. Right hemicolectomy was performed for the appendiceal tumor. The final pathological diagnosis was mucinous cystadenoma with calcified Schistosome eggs within the mucosa and submucosa of the appendix, small intestine, colon, and lymph nodes. We deduced that the pathogenesis of appendiceal mucinous cystadenoma in our case was Schistosome eggs causing luminal obstruction, finally resulting in intraluminal accumulation of mucoid material. Postoperatively, the patient recovered well.

    Primary retroperitoneal mucinous cystadenoma is an extremely uncommon tumor, even though mucinous cystadenoma often develops in the ovary and less frequently in the pancreas. A 21-year-old female was admitted to our hospital due to severe abdominal pain. A well-demarcated, oval shaped cystic tumor at the retropancreatic area with displacement of the pancreas and surrounding major vessels was observed on CT and MRI. Exploratory laparotomy was performed, and complete excision of the entire cyst was performed without complication. The pathologic finding was consistent with primary retropancreatic mucinous cystadenoma. To the best of our knowledge, this report is the first to describe a case of retropancreatic mucinous cystadenoma arising from the retropancreatic area in Korea.

    Full Text Available Serous cystadenoma is a common benign neoplasm that can be managed without surgery in asymptomatic patients provided that the diagnosis is certain. We describe a patient, whose pancreatic cyst exhibited a radiological appearance distinct from that of typical serous cystadenoma, resulting in diagnostic difficulties. CT and MRI showed a 10 cm-polycystic tumor with upstream dilatation of the main pancreatic duct (MPD, suggestive of intraductal papillary mucinous tumor (IPMT. Ultrasonographic aspect and EUS-guided fine-needle aspiration gave arguments for serous cystadenoma. ERCP showed a communication between cysts and the dilated MPD, compatible with IPMT. The patient underwent left pancreatectomy with splenectomy. Pathological examination concluded in a serous cystadenoma, with only a ductal obstruction causing proximal dilatation.

    Full Text Available Two cases of mucinous cystadenoma of the appendix successfully treated by laparoscopy are reported. An 81-year-old woman with lower right back pain was diagnosed with mucinous cystadenoma of the appendix or appendiceal carcinoma and underwent elective laparoscopic surgery. The other case involved a 70-year-old man with hematochezia who was diagnosed with mucinous cystadenoma. He also underwent elective laparoscopic surgery. In these two cases, gauze was folded around the tumors rather than grasping them directly. The postoperative courses were uneventful, and these patients had no recurrent disease at 2-year follow-up. In such cases, surgical excision of the tumor without rupture is of paramount importance because rupture of the lesion can cause pseudomyxoma peritonei. Though appendiceal mucinous cystadenoma has been considered a contraindication of laparoscopic resection, it was possible to achieve this by using a laparoscopic procedure with a gauze technique.

    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

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

    Cystic tumours of the pancreas are heterogeneous lesions with a spectrum of morphology and biological behaviour in people. These are poorly characterized in animals. A multicystic tumour of the pancreas was identified in an 11-year-old, female, mixed breed cat. The tumour was 5.5 cm in diameter and the largest cysts were 1.5 cm in diameter. Microscopically, the cysts were lined by single layered or pseudostratified, flat, cuboidal or columnar epithelial cells that occasionally formed papillary structures with a thin fibrous core. The tumour cells had eosinophilic granules in the apical cytoplasm, similar to zymogen granules, and the nuclei were uniform in size and shape. Mitotic figures were not observed. Immunohistochemically, the tumour cells expressed trypsin, but not cytokeratin 7. A diagnosis of acinar cell cystadenoma of the pancreas was made and this is the first report of this tumour in a cat.

    Endometriosis is a relatively common gynecologic disease affecting women during their reproductive years. For its diagnosis, magnetic resonance imaging has been shown to have greater specificity than other modalities. Although lesions may show variable signal intensity due to numerous stages of bleeding, the characteristic finding of endometrioma which distinguishes it from other ovarian cystic masses is relatively high signal intensity on T1-weighted images and heterogeneous signal intensity with prominent shading on 72-weighted images. We report an atypical case involving a huge endometrioma. Because of varying signal intensity on T1- and T2-weighted images and scanty shading on T2-weighted images, the findings were misinterpreted and mucinous cystadenoma was diagnosed.

    2014-06-01

    A 59-yr-old, captive female African elephant (Loxodonta africana) died of a cardiovascular collapse. Necropsy revealed bilateral replacement of the ovarian tissue by multiple cystic formations of up to 10 cm in diameter. The cysts were thin walled and filled with clear watery fluid. Smaller solid masses with an irregular surface projected from the wall of a few of the cysts. Histologically, the cystic structures were characterized by a single layer of well-differentiated cuboidal epithelial cells resting on a basement membrane. Occasionally the cysts contained nodular proliferations of single-layered, well-differentiated cuboidal epithelial cells forming anastomosing tubules and occasional papillary projections. The ovarian neoplasia was diagnosed as a bilateral multilocular serous ovarian cystadenoma. The nulliparous status and the advanced age may have contributed to the ovarian pathology.

    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.

    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.

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

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

    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

    The most common causes of chronic cholestatic liver disease are primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC). 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.

  2. Evolving Role of Endoscopic Retrograde Cholangiopancreatography in Management of Extrahepatic Hepatic Ductal Injuries due to Blunt Trauma: Diagnostic and Treatment Algorithms

    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.

    The literature is highly conflicting on hepatobiliary mucinous cystic neoplasms (MCNs), aka "hepatobiliary cystadenoma/cystadenocarcinoma," largely because ovarian stroma (OS) was not a requirement until WHO-2010 and is not widely applied even today. In this study, MCNs (with OS) accounted for 24 of 229 (11%) resected hepatic cysts in one institution. Eight of the 32 (25%) cysts that had been originally designated as hepatobiliary cystadenoma/cystadenocarcinoma at the time of diagnosis proved not to have an OS during this review and were thus re-classified as non-MCN. In total, 36 MCNs (with OS) were analyzed-24 from the institutional files and 12 consultation cases. All were women. Mean age was 51 (28 to 76 y). Mean size was 11 cm (5 to 23 cm). Most (91%) were intrahepatic and in the left lobe (72%). Preoperative imaging mentioned "neoplasm" in 14 (47%) and carcinoma was a differential in 6 (19%) but only 2 proved to have carcinoma. Microscopically, only 47% demonstrated diffuse OS (>75% of the cyst wall/lining); OS was often focal. The cyst lining was often composed of non-mucinous biliary epithelium, and this was predominant in 50% of the cases. Degenerative changes of variable amount were seen in most cases. In situ and invasive carcinoma was seen in only 2 cases (6%), both with small invasion (7 and 8 mm). Five cases had persistence/recurrence, 2 confirmed operatively (at 7 mo and 15 y). Of the 2 cases with carcinoma, one had "residual cyst or hematoma" by radiology at 4 months, and the other was without disease at 3 years. In conclusion, many cysts (25%) previously reported as hepatobiliary cystadenoma/cystadenocarcinoma are not MCNs. True MCNs are uncommon among resected hepatic cysts (11%), occur exclusively in females, are large, mostly intrahepatic and in the left lobe (72%). Invasive carcinomas are small and uncommon (6%) compared with their pancreatic counterpart (16%). Recurrences are not uncommon following incomplete excision.

    2015-01-01

    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.

    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.

    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.

    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.

    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

    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.

    Sertoliform cystadenoma of the rete testis represents an uncommon benign tumour. They appear in patients from 26 to 62 years of age. We describe a case of a 66-year-old man with a tumour in the area of the epididymal head. The tumour markers were not increased. Under the assumption of a malignant testicular tumour an inguinal orchiectomy was performed. The cut surface of this tumour was of grey/white color and showed small cysts. The tumour consisted of two compartments. The epithelial like tumour cells showed a sertoliform growth pattern and cystic dilatations. In between the tumour cells repeatedly actin expressing sclerotic areas could be recognized as the second tumour component. Proliferative activity was not increased. Immunohistochemically the tumour cells were positiv for inhibin, S-100, and CD 99. Alpha feto protein (AFP), human chorionic gonadotropin (ß-HCG) and placental alkaline phosphatase (PLAP) as well as synaptophysin, epithelial membrane antigene (EMA), and BCL-2 were not expressed. As far as we know this is the sixth reported case of this tumour. Because of the benign nature of this tumour the correct diagnosis is important for the intra- and postoperative management. Here we present a case of this rare tumour and discuss potential differential diagnosis.

    We report a case of appendiceal mucinous cystadenoma that was successfully diagnosed preoperatively and treated by laparoscopic resection. We could find volcano sign on colonoscopy and cystic lesion without any nodules at the appendix on computed tomography (CT). Without any malignant factors in preoperative examinations, we performed laparoscopic appendectomy including the cecal wall. We could avoid performing excessive operation for cystadenoma with accurate preoperative diagnosis and intraoperative finding and pathological diagnosis during surgery. Appendiceal mucocele is a rare disease that is divided into 3 pathological types: hyperplasia, cystadenoma, and cystadenocarcinoma. The surgical approaches for it remain controversial and oversurgery is sometimes done for benign tumor, because preoperative diagnosis is difficult and rupturing an appendiceal tumor results in dissemination. Based on our study, volcano sign on colonoscopy and CT findings were important for the preoperative diagnosis of appendiceal mucocele. Furthermore, we think that laparoscopic resection will become a surgical option for the treatment of appendiceal mucocele.

    Oncocytic cystadenoma is a benign tumor of salivary glands, histologically characterized by multicystic growth of the oncocytic epithelial lining. Crystals in different shapes and nature associate oncocytic type of salivary gland neoplasms. An 82 year-old woman with right parotideal mass had an operation of superficial parotidectomy. Histological examination revealed multiple unilocular or multilocular cystic lesions with incomplete fibrous capsule, papillary foldings, and 1 or 2 layers of oncocytic epithelium lines. The epithelium lining the cysts were positive for CK8, CK14, CK18, CK19, and negative for SMA, S-100, and p63 immunohistochemically. Cystadenomas were described as mostly multilocular and we presented a multifocal cystic neoplastic lesion lined by oncocytic type epithelial cells with intraluminal crystalloids. Multiple cysts forming morphology, incomplete fibrous capsule of most cysts and immunohistocemical findings were considered as multiple oncocytic cystadenoma with intraluminal crystalloids in the parotid gland.

    2017-02-01

    Appendiceal mucinous cystadenoma can present in various ways, and it is most commonly encountered incidentally during appendectomy, but mechanical intestinal obstruction secondary to an appendiceal mucocele has been rarely reported. We report a case of mechanical intestinal obstruction secondary to appendiceal mucinous cystadenoma. After nasogastric decompression and initial aggressive intravenous fluid resuscitation, an emergency operation was performed under the diagnosis of acute mechanical intestinal obstruction. We performed an appendectomy and intraoperative enteral decompression without anastomoses. The pathologic examination (PE) revealed appendiceal mucinous cystadenoma. After the operation, the patient's recovery went smoothly, and the patient was discharged on the fifth postoperative day. No tumor recurrence was recorded over an 8 month follow-up period. Early operative intervention should be recommended to the patient with acute mechanical complete intestinal obstruction, especially the patient who had no previous abdominal surgery. And it is vital to discriminate benign and malignantappendiceal mucocel in determining the extent of surgery.

    Oncocytic cystadenoma is a rare benign tumor of major salivary glands that in rare occasions may present histologically with intraluminal crystalloids. We report a case of 53-year-old man with a progressively enlarging lump in the left submandibular region. Ultrasound examination revealed a cystic mass with an intraluminal fluid collection. The tumor was surgically removed. Histologic examination yielded a diagnosis of oncocytic cystadenoma with a high concentration of intraluminal crystalloids. The microscopic features of the crystalloids were compatible with nontyrosine (alpha-amylase) crystalloids. When compared with previously published cases in the literature, this is the first report of oncocytic cystadenoma with intraluminal crystalloids arising in the submandibular gland, and the second reported case of the nontyrosine type of crystalloids occurring in association with this tumor. The nontyrosine crystalloids may be highly characteristic to salivary gland tumors with oncocytic differentiation.

    Hydatid disease (HD) is a commonly occurring zoonotic disease caused by tapeworms of the genus Echinococcus. It is endemic in many parts of the world and can involve almost any organ of the body. Although HD of the liver and lungs is quite common, ovarian involvement is rare. We present a case of a 24-year-old female patient who was diagnosed with multifocal hydatidosis involving the liver and bilateral ovaries on imaging. Postoperative histopathology confirmed the hydatid disease in the liver and one ovary. However, the cystic lesion in the other ovary turned out to be a borderline serous cystadenoma. This case highlights the limitation of imaging in differentiating between simple hydatid cysts and serous cystadenomas of the ovaries. Another point we learnt is that even in the presence of multifocal hydatidosis in endemic regions, serous cystadenoma needs to be considered in imaging differential diagnosis.

    Full Text Available Serous cystadenomas are the most common cystic neoplasms of the pancreas. They may occur solely or coexist with other neoplasms. A 10 cm mass involving the body of the pancreas was observed in the computed tomography of a 61-year-old man with a previous history of bladder and prostate carcinoma. Ultrasonography and computed tomography of the mass demonstrated multiple small cysts associated with a central calcified scar. A distal pancreatectomy was performed. Pathological examination confirmed the diagnosis of serous microcystic adenoma. This is the first report of a serous cystadenoma of the pancreas with two metachronous neoplasms. This feature should be kept in mind during the diagnosis and evaluation of patients with serous cystadenoma.

  6. 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 Surface epithelial tumors are most common, which comprise 58% of all ovarian tumors. Serous and mucinous cystadenoma are the most common epithelial tumors which accounts for about 35% of ovarian tumors. Different combinations of epithelial tumors can occur in ovary most common among them is Mucinous cystadenoma and Brenner tumor. We report a case of an ovarian tumor with rare combination Brenner tumor with serous cyst adenoma of ovary in 56 year old female patient. Only a few cases with this combination are very rarely reported in the literature.

    Summary A 2-year-old captive-born male moustached tamarin was subjected to necropsy examination after a fatal head trauma. A solitary, circumscribed, subpleural mass (0.6 cm diameter) was found in the right caudal lung lobe. The mass was diagnosed as a mucinous cystadenoma. Histochemical and immunohistochemical tests were performed to further characterize the tumour. Surfactant proteins A, B, C and D were not found in the neoplastic cells, suggesting that the tumour arose from a non-surfactant producing alveolar lining cell. Pulmonary mucinous cystadenomas are uncommon benign tumours in man and have not been reported previously in animals. PMID:23356933

    Giant ovarian adenomas are rarely observed today because of early diagnosis and treatment. Mucinous cystadenomas is a kind of tumor that mostly causes the ovary to enlarge. Theu can present with various and non-specific clinical manifestations such as deep vein thrombosis. The primary symptoms of giant ovarian tumors are abdominal enlargement and distension. Therefore, making the correct preoperative diagnosis is sometimes difficult. The appropriate treatment must include oncologic procedures and a multidisciplinary approach to minimalize complications and save the patient's life. Herein, we report a woman aged 53 years with a 27-kg ovarian mucinous cystadenoma that presented as a left popliteal vein thrombosis.

    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.

    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.

    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.

    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 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.

    Patients with von Hippel-Lindau (VHL) disease develop tumors in a range of tissues, but existing mouse models of Vhlh mutation have failed to reproduce these lesions. Epididymal cystadenomas arise frequently in VHL patients, but VHL mutation alone is believed to be insufficient for tumor formation, implying a requirement for cooperating mutations in epididymal pathogenesis. Here we show that epididymal cystadenomas from VHL patients frequently also lack expression of the PTEN tumor suppressor and display activation of phosphatidylinositol 3-kinase (PI3K) pathway signaling. Strikingly, while conditional inactivation of either Vhlh or Pten in epithelia of the mouse genital tract fails to produce a tumor phenotype, their combined deletion causes benign genital tract tumors with regions of squamous metaplasia and cystadenoma. The latter are histologically identical to lesions found in VHL patients. Importantly, these lesions are characterized by expansion of basal stem cells, high levels of expression and activity of HIF1α and HIF2α, and dysregulation of PI3K signaling. Our studies suggest a model for cooperative tumor suppression in which inactivation of PTEN facilitates epididymal cystadenoma genesis initiated by loss of VHL. PMID:18474617

    Background: Primary retroperitoneal mucinous cystadenoma is a rare neoplasm, with benign biological behavior. Delay in diagnosis and treatment of this tumor may be fatal for the patient, because of complications, such as rupture, infection and malignant transformation. Case presentation: We present a 23-year-old woman, who was admitted to the hospital because of a palpable abdominal mass and discomfort since 4 months. Computed Tomography and Magnetic Resonance Imaging scans were performed and showed two retroperitoneal cystic masses, which were excised by laparoscopy. Histological and immunohistochemical examination revealed that the inner surfaces of the cysts were lined by epithelium with features of mesothelial cells, in addition to ovarian mucinous cystadenoma. This is the 29th case and the second reported case with two contemporary cysts. Conclusion: The origin of retroperitoneal mucinous cystadenomas is still unclear. Pathological and immunohistochemical findings proved that these tumors resemble ovarian mucinous cystadenomas but are unattached to the ovary and can arise at any location in the retroperitoneum. Surgical excision of the aforementioned tumors is the treatment of choice. Hippokratia 2014; 18 (3): 278-281. PMID:25694766

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

    Mucinous cystadenoma is the most common of benign neoplasms of the appendix and carcinoid is the most common type of primary malignant lesions of the appendix.We report a rare case of a 57-year-old female with combined mucinous cystadenoma and carcinoid tumor of the appendix.Dual carcinoid and epithelial neoplasia is a rare occurrence in the appendix. A 57-year-old Caucasian woman presented after incidentally palpating a mass on her right iliac fossa. Imaging modalities revealed a cystic tumor in the right iliac fossa with a diameter of about 8 cm, originating either from the right ovary or the appendix. She underwent laparoscopic surgical exploration, which revealed appendiceal mucocele and appendicectomy was finally performed as well as excision of a right ovarian cyst. Pathological examination showed acollision tumor consisting of mucinous cystadenoma and carcinoid tumor of the appendix. Because of the size and extension of the carcinoid tumor, which the pathology report revealed, she underwent re-exploration and laparoscopic right colectomy. Mucinous cystadenoma is rare, but it is the commonest of benign appendiceal tumours accounting for 0.6% of appendectomy specimens. It can present as appendicitis,mucocele or if the tumour ruptures, as pseudomyxomaperitonei. On the other hand, carcinoid is the most common type of primary malignant lesion of the appendix and 0.3-0.9%of appendectomy specimens, with small predominance in female patients. Rare cases of mucinous cystadenomas of the appendix coexisting with carcinoid tumors were reported before, but in our case it was a collision tumor with no transitional zone between them. Also, the clinical presentation of our patient and the differential diagnosis of ovarian lesions from appendiceal tumors is worth being mentioned. Celsius.

    A long-term follow up case of hepatobiliary cystadenoma originating from simple hepatic cyst is rare. We report a case of progressive morphologic changes from simple hepatic cyst to hepatobiliary cystadenoma by 11 - year follow up imaging. A 25-year-old man visited our hospital in 1993 for a simple hepatic cyst. The cyst was located in the left lobe of the liver, was 6 cm in diameter, and did not exhibit calcification, septa or papillary projections. No surgical treatment was performed, although the cyst was observed to gradually enlarge upon subsequent examination. The patient was admitted to our hospital in 2004 due to epigastralgia. Re-examination of the simple hepatic cyst revealed mounting calcification and septa. Abdominal CT on admission revealed a hepatic cyst over 10 cm in diameter and a high-density area within the thickened wall. MRI revealed a mass of low intensity and partly high intensity on a T1-weighted image. Abdominal angiography revealed hypovascular tumor. The serum levels of AST and ALT were elevated slightly, but tumor markers were within normal ranges. Left lobectomy of the liver was performed with diagnosis of hepatobiliary cystadenoma or hepatobiliary cystadenocarcinoma. The resected specimen had a solid component with papillary projections and the cyst was filled with liquid-like muddy bile. Histologically, the inner layer of the cyst was lined with columnar epithelium showing mild grade dysplasia. On the basis of these findings, hepatobiliary cystadenoma was diagnosed. We believe this case provides evidence of a simple hepatic cyst gradually changing into hepatobiliary cystadenoma.

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

    Directory of Open Access Journals (Sweden)

    Tomoki Yagai

    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.

    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.

  10. Hepatic and biliary ascariasis

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

    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.

    At one time it was thought that biliary epithelial cells simply formed the lining to the tubular conduits which constitute the biliary tract. 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...

    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.

  16. 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.

  17. Primary biliary cirrhosis

    Kumagi, Teru; Heathcote, E Jenny

    2008-01-01

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

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

    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.

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.

The purpose of our study was to examine and compare detailed contrast-enhanced ultrasonography (CEUS images of SCAs and MCAs and to determine whether there are significant findings that can contribute to the discrimination between these two diseases. Methods: From April 2015 to June 2016, 61 patients (35 patients with SCAs and 26 patients with MCAs were enrolled in this study. Forty-three cases were confirmed by surgical pathology and 18 by comprehensive clinical diagnoses. All of the CEUS characteristics of these lesions were recorded: size, location, echogenicity, shape, wall characteristics, septa characteristics, and the presence of a honeycomb pattern or nodules. CEUS examinations were performed by two ultrasound physicians. Results: Location (P=0.003, shape (P=0.000, thickness of the wall (P=0.005, the number of septa (P=0.001, and the honeycomb pattern (P=0.001 were statistically significantly different. A head–neck location, a lobulated shape, an inner regular honeycomb pattern, and a thin wall (<3 mm thick were significant in diagnosing patients with SCAs. When two of these four findings were combined, we could achieve a sensitivity of 71.4% and a specificity of 80.8% to diagnose SCA; when three of these four findings were combined, the specificity was 100%. A body–tail location, a round/oval shape, 0–2 septa, and a thick wall (≥3 mm thick were most often detected in patients with MCAs. When two of these four findings were combined, we could achieve a

    Full Text Available A 22-year-old patient with 9 months of amenorrhea and a huge abdominal swelling was admitted to our institution with an ultrasonography report of a multiloculated cystic space-occupying lesion, almost taking up the whole abdomen (probably of ovarian origin, along with a single live intrauterine fetus. She delivered vaginally a boy baby within 4 hours of admission without any maternal complication, but the baby had features of intrauterine growth restriction along with low birth weight. On the 8th postpartum day, the multiloculated cystic mass, which arose from the right ovary and weighed about 11 kg, was removed via laparotomy. A mucinous cystadenoma with no malignant cells in peritoneal washing was detected in histopathology examination. This report describes a rare case of a successful vaginal delivery despite a huge cystadenoma of the right ovary complicating the pregnancy.

    Full Text Available Mucinous cystadenomas of the pancreas are rare tumors appearing usually within the body and the tail of the pancreas in a young and middle-aged women. They rarely communicate with the pancreatic duct and occasionally may become malignant. The authors present a patient with a number of rare features. In a 52 year-old male, we did a radical pylorus-preserving cephalic duodenopancreatectomy for a mucinous cystadenoma within the head of the pancreas, which perforated into the main pancreatic duct causing chronic obstructive pancreatitis having few foci of malignant alteration. The postoperative recovery was uneventful, but three months later the patient died due to exacerbation of the underlying serious heart disease. .

    We Describe a case of ovarian serous cystadenoma having Sertoli-Leydig cell tumor, well differentiated, in the cystic septum. Well differentiated Sertoli-Leydig cell tumor coexisting with other tumor, including serous tumor, has not yet been described. In all cases of Sertoli-Leydig cell tumor with heterologous components or other tumors, the androblastomatous components are intermediately or poorly differentiated. The present case revealed a well differentiated Sertoli-Leydig cell tumor arising in a septum of serous cystadenoma, as a circumscribed nodule. With these findings, we discuss the possibility of this Sertoli-Leydig cell tumor, considered a mural nodule, which is well established in cystic common epithelial tumors of the ovary. PMID:8703377

    An 85-year-old male experienced a painless swelling along the left lateral orbit for one year. A computed tomography scan demonstrated a cystic mass in the orbit adjacent to the lacrimal gland. There was a concern for malignancy considering the large size and the patient's age, so the tumour was excised. Histopathology of the tumour showed nests with basaloid patterns, but a definitive diagnosis was not rendered. The uncertainty of tissue diagnosis coupled with the basaloid pattern, which carries a grim prognosis in some salivary gland tumours, led us to refer this case to an authority on lacrimal gland pathology, who suggested that this tumour be called a basal cell cystadenoma. To the best of our knowledge, a basal cell cystadenoma of the lacrimal gland has not been reported in the literature. We present histopathological features that distinguish this tumour from malignant tumours with a basaloid pattern. We also discuss the management differences associated with basaloid patterns in lacrimal tumours.

Patient was admitted in our hospital with abdominal pain of one-month duration. On abdominal ultrasound, a huge heterogeneous mass was found to encompass the whole abdomen. At laparotomy, a giant, right heterogeneous mass was encountered and removed intact by right salpingo-oophorectomy. On the seventh postoperative day, she was discharged without any problem. Her pathology report disclosed a 52 x 41 x 36 cm, partially solid, partially cystic mass diagnosed as benign Brenner's tumor with mucinous cystadenoma weighing 20.7 kg. This is the largest ovarian mass that is ever reported in our hospital and one of the largest among the reported cases in the literature.

    Serous tumors can occur on the surface of the ovaries and-rarely-as primary tumors on the peritoneal surface. However, the origin of extraovarian serous tumors is unknown. An unusual case of a serous tumor is presented here. A 34-year-old nulligravid woman presented for evaluation of her primary infertility, with acute abdominal pain. At laparoscopy, a paratubal cyst, independent of the ovaries, was found to be associated with bilateral hydrosalpinges. The final pathology diagnosis was of a benign paratubal serous cystadenoma. We present an unusual case of a paratubal serous cystadenoma with bilateral hydrosalpinges in an infertile woman, which was resected laparoscopically.. Copyright © 2014. Published by Elsevier B.V.

    Ovarian teratoma has various presentations. We present a 28-year female diagnosed with a tumour after a fainting episode. Medical history was non-contributory except for mild intermittent pelvic pain. Cardiologic and neurological evaluation found no cause of syncope. Abdominal ultrasound revealed a right ovarian tumour that was laparoscopically removed. The menses continued to be normal. The pathological exam showed an encapsulated tumour of 8 cm with hair and small bone parts (mature teratoma with a cystadenoma). Immunohistochemistry was positive for CK34beta E12 in stratified squamous epithelium of skin glands; positive CK7 in kidney tubular parts; positive actin in smooth muscle. The endocrine profile was normal and the patient remained asymptomatic. The challenging in the pathological report was to differentiate a cystic part of a solid tumour to a teratoma associated cystadenoma. No apparent cause of syncope was found so a possible tumour related local pain and inflammation mechanism might be involved.

    Objective: Laparoscopic reduction of appendicocecal intussusception due to mucinous cystadenoma is herein described. Methods: A 32-year-old female had intermittent abdominal pain and nonbloody diarrhea. The preoperative diagnosis was intussusception of the colon with a benign tumor by CT-scan findings. Results: Laparoscopic reduction of intussusception and ileocecal resection were successfully performed. Gauze sponge sticks were used to provide compression from the distal colon. This maneuver was very effective to reduce the intussusception. Conclusion: Laparoscopic reduction of intussusception due to a benign tumor is feasible and safe even in adults. Mucinous cystadenoma is one of the causes of intussusception in adults and a good indication for the laparoscopic approach. PMID:15347119

    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.

    Full Text Available Mucinous cystadenoma of the urinary bladder is a very rare tumor and only a handful of cases have been described in the literature. It can easily be missed on cystoscopic examination as the lesion is not intramucosal. In addition, extensive workup is required to rule out borderline or frank malignant neoplasm elsewhere in the body. Due to its scarcity and diagnostic challenges, we report a mucinous benign cystic lesion arising in the dome of the urinary bladder.

    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.

    2010-09-01

    An unusual case of ovarian adenosarcoma arising from a smooth-walled serous cystadenoma is described. The ovary was replaced by a multiloculated, fluid-filled cyst without any solid or papillary areas. The malignant component was underdiagnosed during frozen section examination as benign cystadenoma because of the deceptively benign gross appearance of the tumor. On the permanent sections, a phyllodes-like pattern of stromal proliferation and periglandular condensation of atypical stromal cells with a mitotic count of 3 per 10 high-power fields was more apparent and led to the diagnosis of adenosarcoma. The malignant component could not be distinguished from the benign component using immunohistochemical analysis. To our knowledge, this is the first reported case of an adenosarcoma arising from a grossly benign cystadenoma and the third case in the literature of an adenosarcoma associated with a cystadeno(fibro)ma. This case also shows the challenges in differentiating adenosarcoma from a benign counterpart on both frozen and permanent sections.

    We report a hitherto not documented case of primary mucinous cystadenoma arising in the spermatic cord within the right inguinal canal of a78-year-old man. The tumor was painless, hard and mobile. A computed tomography scan on the pelvis revealed an oval shaped, low attenuation mass, measuring 5.0x2.5x2.1 cm, that was present adjacent to the vas deferens. Grossly, the excised mass was multicystic mucinous tumor, filled with thick mucoid materials. Microscopically, the cystic wall was irregularly thickened. The cystic epithelium commonly showed short papillae lined by a single layer of columnar to cuboidal mucinous epithelial cells without significant stratification or cytologic atypia. Goblet cells were also frequently present. Immunohistochemically, the neoplastic cells showed positive reaction to carcinoembryonic antigen, cytokeratin 20, CDX2, epithelial membrane antigen, and CD15. However, they were negative for PAX8 and Wilms' tumor 1 protein. Pathological diagnosis was a papillary mucinous cystadenoma of the spermatic cord. Although mucinous cystadenoma in this area is extremely rare, it is important that these lesions be recognized clinically and pathologically in order to avoid unnecessary radical surgery.

    1998-01-01

    Full Text Available A 38-year-old female with systemic lupus erythematosus presented with abdominal pain, diarrhea and iron-deficient anemia. Computed tomogram showed a 2x4 cm inhomogeneous lesion of the right adnexa. An unusual mass was identified extending from the appendiceal orifice at colonoscopy, and an 8 cm tubular appendix, apparently prolapsed into the cecum, was identified at celiotomy. An appendectomy with cecectomy was performed. On cut section, mucin was extruded from the lumen of the appendix. A mucinous neoplasm of the appendix with mucinous dissection to the serosal surface was reported at the time of frozen section. No gross ovarian pathology or peritoneal implants were noted. Cystadenoma with associated mucocele formation was verified by permanent histology. Mucocele of the vermiform appendix is a rare condition associated with neoplastic transformation in approximately 75% of all cases. Benign mucinous cystadenoma of the appendix should be differentiated from cystadenocarcinoma by frozen section at the time of celiotomy to ensure appropriate treatment. While systemic lupus erythematosus can lead to cutaneous mucinosis, an association with mucinous cystadenoma of the appendix has not been previously reported. Surveillance for metachronous colonic neoplasms is warranted in patients diagnosed with a mucinous neoplasm of the appendix.

    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.

    To determine whether or not detailed cystic feature analysis on CT scans can assist in the differential diagnosis of pancreatic ductal adenocarcinoma (PDAC) from serous cystadenoma (SCN), mucinous cystadenoma (MCN), and a pseudocyst. This study received Institutional Review Board approval and informed patient consent was waived. Electronic radiology and pathology databases were searched to identify patients with PDAC (n = 19), SCN (n = 26), MCN (n = 20) and a pseudocyst (n = 23) who underwent pancreatic CT imaging. The number, size, location, and contents of cysts, and the contour of the lesions were reviewed, in addition to the wall thickness, enhancement patterns, and other signs of pancreatic and peripancreatic involvement. Diagnosis was based on lesion resection (n = 82) or on a combination of cytological findings, biochemical markers, and tumor markers (n = 6). Fisher's exact test was used to analyze the results. A combination of the CT findings including irregular contour, multiple cysts, mural nodes, and localized thickening, had a relatively high sensitivity (74%) and specificity (75%) for differentiating PDAC from SCN, MCN, and pseudocysts (p < 0.05). Other CT findings such as location, greatest dimension, or the presence of calcification were not significantly different. The CT findings for PDAC are non-specific, but perhaps helpful for differentiation. PDAC should be included in the general differential diagnosis of pancreatic cystic neoplasms

    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.

    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.

  7. 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.

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

    Directory of Open Access Journals (Sweden)

    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.

    1994-01-01

    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 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.

  12. Biliary atresia. A surgical perspective.

    Science.gov (United States)

    Ohi, R

    2000-11-01

    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.

    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.

    2014-01-01

    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.

    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.

    Laminopathies are a group of rare genetic disorders characterized by multiple-tissue degeneration. We describe a new laminopathy with ovarian cystadenoma and explore its molecular etiology. The case is a 15-year-old girl who presents the prominent progeroid disorders, multiple system degeneration and early-onset cystadenoma of the ovary. Candidate genes including LMNA, ZMPSTE24, PPAR G, INSR and WRN were sequenced to screen for DNA variants. The mRNA and protein expression levels of LMNA were examined in primary fibroblasts. The pathophysiological events such as morphologic alterations, cell senescence, cell proliferation, apoptosis and pRb as well as p53 protein expressions were also investigated in primary fibroblasts. No mutation was identified in the candidate genes screened. Nuclear abnormalities including nuclear blebs, mislocalization of lamin A/C were evident in the patient fibroblasts. Ultrastructurally, nucleus exhibited nuclear herniation and almost complete loss of peripheral heterochromatin. In addition, lamin C protein expression was markedly reduced whereas lamin A protein level was normal and no prelamin A was detected in the primary fibroblasts. Although the senescence-associated beta-galactosidase staining of patient' cells was negative, cells in S phase increased in accompany with a decrease in pRb protein expression. Furthermore, increases in apoptotic cell death and p53 expression were observed. Our data suggest that selective deficiency of lamin C protein is associated with a case of laminopathy with ovarian cystadenoma. The abnormalities in nuclear structure and alterations in gene expression such as the decrease in pRb and increase in p53 may be responsible for the multiple tissue degeneration.

    A 19-year-old man presented with a right testicular swelling. Testicular ultrasound demonstrated areas suspicious for malignancy and so it was decided to proceed for a right radical inguinal orchiectomy. Initial histological examination revealed a multiloculated cystic lesion at the area of the rete testis yet normal testicular parenchyma elsewhere. Specialist histological opinion was sought from the regional teratoma multi-disciplinary team which confirmed the diagnosis of a sertoliform cystadenoma, an extremely rare benign testicular neoplasm. The recognition of the benign nature of the mass enabled complete reassurance to be offered to the patient and avoided further oncological treatment.

    Appendiceal diverticulosis is a rare condition with a frequency of 0.004% to 2.1%, and is sometimes an occasional finding during anatomopathologic study of the surgical specimen. It may be presented acutely as a right lower quadrant pain, similar to acute appendicitis for which differential diagnosis must be carried out, and it is associated with appendicular tumors. We report a case of diverticulitis of the appendix as debut of appendicular cystadenoma and carcinoid tumor with representative iconography, being unusual the association of both diseases and even more its preoperative diagnosis.

    Cosmin Alec Moldovan

    2016-10-01

    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.

    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.

    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.

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

    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.

    Full Text Available Abstract Background Mucinous cystic neoplasm (MCN of the pancreas is basically cystic epithelial neoplasm, unilocular or multilocular, occurring almost exclusively in women. Case presentation A 51-year-old female presented with a pancreatic mass incidentally found on the abdominal computed tomography. She underwent distal pancreatectomy. The sectioned surface of the pancreas revealed a circumscribed, whitish gray ovoid firm mass with some cystic spaces. Microscopically, glandular or small cystic structures were scattered in the predominant stroma creating a solid appearance. The subepithelial stromal component was composed of cytologically bland looking spindle cells, which resembled ovarian stroma. The stromal cells were reactive to CD 34, vimentin, progesterone receptor and calretinin. The microscopy was consistent with mucinous cystadenoma of the pancreas. Conclusion This case of mucinous cystadenoma of the pancreas showed very interesting pathology: It was solid rather than cystic, and accompanied by abundant benign transitional epithelia, which was a very unusual and novel finding in the mucinous cystic neoplasm of the pancreas.

    Hepatobiliary cystadenoma complication with congenital choledochal cyst is extremely rare and has never been reported in literatures so far.The aim of the study was to investigate the disease arrangements by analyzing the case and performing a systematic review of the literature.This case report documents the details and clear patterns of the patient. A 65-year-old woman with fever (39.2°C), nausea, vomiting, and chronic hepatitis B imaging demonstrated a left hepatic multilocular cystic mass and cystic dilated common bile duct.A regular left hemihepatectomy was performed with resection of the entire tumor and choledochal cyst.The surgical margins were negative and a final diagnosis of hepatobiliary cystadenoma complicated with congenital choledochal cyst was established. The patient had an uneventful postoperative recovery and liver function returned to normal levels.Main lessons learned from this case are: the awareness should be raised about the disease to avoid misdiagnosis; preoperative ultrasonography, computed tomography, magnetic resonance imaging, and magnetic resonance cholangiopancreatography play an important role in detecting the lesion; the scope and timing of the surgery should be determined, which provide the chance of cure to complete resection of the tumor.

  13. Biliary Ascariasis: A difficult extraction

    2015-01-01

    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 evaluate the radiologic findings of the serous cystadenomas of the pancreas with macrocystic or unilocular variants and to compare them with the pathologic findings. In eight patients (7 females and 1 male ranging in age from 26 to 49 (mean, 37) years) with surgically proven serous cystadenomas, the findings of abdominal CT (n=3D8), abdominal sonography (US, n=3D8), endoscopic retrograde pancreatography (ERCP, n=3D6), endoscopic sonography (EUS, n=3D3), and MRI (n=3D1) were evaluated. The location and size of tumors, lobulation, internal septa, solid component, calcification, communication with the pancreatic duct, dilatation of the proximal pancreatic duct, and contrast enhancement on CT were assessed and compared with the pathologic findings. Tumors were located in the head (n=3D3), body (n=3D3) and tail (n=3D2), and their mean size was 4 (range, 1-8)cm. Abdominal CT scanning revealed well-defined cystic masses composed of macrocyst(s) with calcification (n=3D3) and dilatation of the proximal duct (n=3D2). Three cases showed contrast enhancement of the cystic walls, the pathologic examination of which revealed fibrotic tissues. Four tumeurs were unilocular without septation or lobulation; these features, together with calcification, were depicted more clearly by US and EUS. ERCP revealed no communication between the cysts and pancreatic ducts. Imaging studies showed that macrocystic adenomas were superimposed on mucinous cystadenomas, and unilocular adenomas were indistinguishable from pseudocysts. Serous cystadenomas of the pancreas with macrocystic or unilocular variants are common in middle-aged women. Features present due to the existence of fibrotic tissues, and which may be reveled by contrast-enhanced CT, include internal septa, calcification, duct dilation, and prominent enhancement of the cystic wall. Serous cystadenoma should be included in the differential diagnosis of macrocystic or unilocular cystic lesions of the pancreas. (author)

    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. In the GLM analysis of Lg(S/D), the P values of Group Effect, Time Effect, and Time×Group were 0.014, 0.376, and 0.008, respectively. Our results show a relatively reduced hepatic artery S/D in ITBL, especially in extrahepatic ITBL. Copyright © 2016 Elsevier Inc. All rights reserved.

    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.

    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 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.

    Salivary gland tumors are uncommon and constitute 2-6.5 % of all head and neck neoplasms. Tumors of minor salivary gland origin account for less than 25 % of all salivary gland neoplasms. Papillary cystadenoma of salivary glands is a rare benign epithelial neoplasm characterized by multicystic growth in which the epithelium exhibits adenomatous proliferation. Papillary cystadenoma of minor salivary glands most frequently involves the lip, buccal mucosa, and palate. This tumor typically presents as a slow-growing, painless mass, usually with diameter of less than 1 cm and clinical resemblance to a mucocele. Although most papillary cystadenomas are predominantly of one cell type, a regional variability may be present. We present a case of papillary cystadenoma of the minor salivary glands in a 58-year-old patient exhibiting an upper respiratory tract epithelium, a profoundly atypical benign tumor. This type of minor salivary gland tumor epithelium in the lower lip may be the result of a metaplastic process or simply another neoplastic manifestation of papillary cystadenoma. As far as the differential diagnosis of this entity is concerned, it is important to distinguish it from papillary cystadenoma lymphomatosum (Warthin's tumor), low-grade mucoepidermoid carcinoma, the papillary-cystic variant of acinic cell carcinoma, and cystadenocarcinoma Recognition of this lesion is important for the clinician since the differential diagnosis includes lesions with similar clinical appearance and infiltrative behavior.

    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.

  13. Biliary cysts: Etiology, diagnosis and management

    2012-01-01

    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.

    2013-07-01

    Acinar cell cystadenoma (ACC) of the pancreas was first described as a distinct pancreatic cystic neoplasm in 2002. We have encountered three cases of ACC at our institution in addition to the 15 cases reported to date in the world literature. The gender distribution in the total cohort of patients with ACC slightly favored females (61 % female), and the median age was 49.5 years. Almost half (53 %) of the cases were identified incidentally, while the remainder presented with abdominal pain. The median tumor diameter was 5 cm in size, and no patients have had documented disease recurrence or progression, even in the setting of an incomplete resection. These findings suggest a relatively indolent biology, and that complete resections are curative. As we will show, surgical resection is warranted to treat symptoms and prevent local extension or malignant transformation.

    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.

    2016-07-01

    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.

    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

  1. Laparoscopic approach to mucocele of appendiceal mucinous cystadenoma: feasibility and short-term outcomes in 24 consecutive cases.

    Mucocele of the appendix is an uncommon condition where luminal distention by mucin is usually attributable to a mucinous cystadenoma. From a surgical standpoint, it is critical that the mucin-filled tumor remains intact during resection. Spillage of mucin into peritoneal cavity may otherwise lead to pseudomyxoma peritonei. Although acute appendicitis is managed successfully by laparoscopic appendectomy, the potential for rupture has fueled concerns over laparoscopic resection of appendiceal mucoceles. Our aim was to evaluate feasibility, safety, and short-term outcomes of laparoscopic resection in patients with a mucocele of appendix secondary to mucinous cystadenoma. Data collected prospectively at the Department of Surgery from October 2005 to December 2013 were reviewed, selecting all instances of preoperatively identified appendiceal mucoceles, which was confirmed as mucinous cystadenomas by histology after elective laparoscopic surgery. Patient demographics, surgical data (operative procedures and times, intraoperative complications), and short-term postoperative outcomes were analyzed retrospectively. Twenty-four consecutive patients (female 14) were studied. Mean age was 60.0 years (range 42-81 years). Surgical procedures included simple appendectomy (1/24, 4.2 %), partial cecectomy (15/24, 62.5 %), and ileocecal resection (8/24, 33.3 %). Mean operative time was 108.5 min (range 40-205 min). No intraoperative spillage of mucin occurred due to inadvertent rupture of tumor. Resection margins uniformly were negative for tumor. Mean maximal length and diameter of tumors were 7.9 cm (range 3.0-20.0 cm) and 3.2 cm (range 1.0-7.5 cm), respectively. One patient (4.2 %) suffered postoperative morbidity (wound infection). A laparoscopic approach proved feasible and safe for surgical management of appendiceal mucocele due to mucinous cystadenoma. However, long-term follow-up is warranted for more conclusive support.

    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.

    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.

    2012-01-01

    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.

    2000-11-01

    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.

    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.

    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.

    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.

    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.

    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.

    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 describe a unique apocrine cystadenoma of the superonasal eyelid and anterior orbit. Clinical evaluation with axial and coronal CT; histopathologic and immunohistochemical studies including sections stained with hematoxylin-eosin, periodic acid Schiff, alcian blue, mucicarmine, and Prussian blue for iron; and monoclonal antibodies against cytokeratin-7, epithelial membrane antigen, smooth muscle actin for myoepithelial cells, gross cystic disease fluid protein-15 for apocrine differentiation, and CD-68 and lysozyme for histiocytes. The cyst possessed a multilaminar lining composed of polygonal to low cuboidal cells. A stalk of solid tumor ingrowth from the wall was composed of adenomatous units of eosinophilic cells with apical snouts ("decapitation secretion"). No goblet cells were discovered. Both the cyst's lining cells and the adenoma expressed gross cystic disease fluid protein-15 indicative of apocrine differentiation. The adenoma displayed inner adlumenal cells that were CK-7 and epithelial membrane antigen positive, and outer myoepithelial cells that were smooth muscle actin positive. Simple local excision was curative. This unique lesion is the first example in the ophthalmic and dermatopathologic literatures of a solid adenoma encompassed by an apocrine cyst, which more typically features short or blunt papillae. It must be distinguished from other eyelid and/or anterior orbital cystic lesions including eccrine hydrocystomas; classical and extratarsal dermoid cysts; congenital and acquired conjunctival cysts and dermoids; dacryocystocoeles/mucoceles; canaliculops and lacrimal gland dacryops; and congenital cystic odontogenic choristomas.

    Full Text Available The papillary cystadenoma lymphomatosum (PCL, also called warthin's tumor, is a benign salivary gland tumor which primarily involves the parotid gland. These lesions are composed of a double layer of cuboidal or culmnar eosinophilic cells lining a cystic cavity which lymphoid tissue is present in the supporting stroma. The lesions shows a predilection for males, with peak incidence during the sixth decade of life. Bilateral lesions have been found to occur in 5 to 7.5 percent of the cases. Rarely, these lesions have been reported in the minor salivary glands and oropharynx. Case report: A 47-year-old woman presented with a red lesion on the hard palate between the midline and right maxillary side. The patient had awared of the lesion for one year. The clinical dignosis was a mucocele. An excisional biopsy was performed. Gross examination of the formaline-fixed specimen revealed three pieces of soft tissue measuring 1.0 x 0.3 x 0.3. Histologic examination revealed a nodular mass surfaced by keratinizied stratified squamous epithelium. The connective tissue stroma contained a papillary cystic area lined by a double layer of cuboidal cells with centrally placed nuclei

    Although cystic neoplasms of the pancreas are an uncommon disease, it occurs often enough that proper surgical management depends on accurate preoperative diagnosis. It is very different to diagnose accurate by conventional radiological methods alone. Angiographic findings are fairly characteristic for these tumors, but they are in no way specific. The imaging characteristics of ultrasonography and computed tomography are particularly useful in the diagnosis of this particular tumors. This report presents an analysis of 2 cases of cystadenoma and 3 cases cystadenocarcinoma examined by ultrasonography and computed tomography. Ultrasonographic findings are complex multicystic mass in the pancreas with thick irregular wall, daughter cyst,, septa and solid component. These septa and solid component are highly echogenic if the tumor is mucin producing. Computed tomographic findings are large cyst possessing irregular thick wall, solid component and septa which are enhanced by contrast infusion. Punctate or curvilinear calcification is seen occasionally. Tortuous or beaded vascular collaterals are seen around the cyst. On the other hand, pseudocyst is usually a single cyst possessing thin smooth wall, and solid component or septa are unusual in pseudocyst.

    The mucinous cystadenoma, a common benign neoplasm of the ovary, may sometime bring about a fatal outcome known as pseudomyxoma peritonei which is characterized by massive accumulation of mucinous substance in the peritoneal cavity, resulting in extensive adhesions, chronic progressive intestinal obstruction and finally death of the patient. Surgical approach to this condition proves to be a palliative procedure. Repeated operation can only remove part of the geletinous material and reaccumulation of mucus within 1-2 years after the initial surgery is almost a rule. In view of the benign histologic nature of the disease, chemotherapy, either systemic or intraperitoneal, and radiotherapy are generally ineffective in arresting the progression of the pathologic process and preventing the reaccumulation of mucus. Therefore, the only hope lies on the introduction into the peritoneal cavity some agents which may dissolve the accumulated mucin, relieve the intestinal obstruction, and consequently, prolong and even save the life f the patient. Based on this conception, sporadic articles by a few authors(1,2)ap-peared in the literature reporting their clinical experience with different mucolytic agents. However, some blindness would inevitably be involved in such investigations due to the lack of a comprehensive understanding of the chemical structures of the substance. The purpose of the present paper is to report our preliminary results of study of the secondary structures of mucin secreted by this special type of tumor.

    Pancreatic serous cystadenomas (SCAs) are benign tumors. Technological advances in imaging have led to increased recognition of asymptomatic pancreatic cysts, consequently increasing the demand for cytomorphologic evaluations of cyst fluid. A retrospective search through the pathology archives over an 11-year period was performed to identify SCAs from pancreatectomy specimens with a presurgical pancreatic EUS-guided fine-needle aspiration (FNA). Fifty-one FNAs were identified. The average patient age was 59.9 years and 34 (67%) were female. Thirty-five (69%) of the SCAs were located in the body or tail of the pancreas. SCAs ranged in size from 1.3 to 8.0 cm (mean 4.9). On imaging, features suggestive of SCA were seen in 7 (14%) cases. The cytologic diagnoses were as follows: SCA in 5 (10%) cases, suspicious for mucin-producing neoplastic cyst in 4 (8%), pseudocyst in 4 (8%), and benign ductal and/or acinar epithelium, not otherwise specified in 24 (47%). Additionally, 14 (27%) cases were deemed nondiagnostic. A cytopathologic diagnosis of SCA on FNA is extremely difficult. The salient cytomorphologic features for identifying SCAs included scant cellularity, a mostly clear background, absence of extracellular mucin, hemosiderin-laden macrophages, and loose fragments of cuboidal cells with a notable absence of necrosis, atypia, and mitoses. © 2016 S.

    Acinar cell cystadenoma (ACC) is a recently recognized cystic lesion of the pancreas that demonstrates acinar differentiation and is currently believed to behave in a benign fashion. ACC enters the differential diagnosis of pancreatic cystic lesions alongside better recognized entities such as mucinous cystic and intraductal papillary mucinous neoplasms. Although uncommon, patients with ACC can undergo fine needle aspiration (FNA) of the lesion. However, the diagnosis is rarely made on cytologic examination due to sparse cellularity. Furthermore, the eosinophilic amorphous material in the cyst lumen may be mistaken for mucin, resulting in an incorrect diagnosis of a mucinous cyst. To date, there is a paucity of literature on the cytomorphology of ACC, both in peer-reviewed publications and cytopathology texts. To our knowledge, we present the first detailed case report of FNA of ACC in a 22-year-old asymptomatic female. The FNA cytology specimen was hypocellular, and the presence of amorphous secretions led to the initial diagnosis of a mucinous-type neoplasm. Following surgical resection, the cytology specimen was reviewed. We discuss the cytomorphologic features of ACC along with the potential pitfalls and diagnostic implications. © 2014 S.

    Serous cystadenoma (SC) is a benign pancreatic cystic tumor. Surgical resection is recommended for symptomatic forms, but laparoscopic fenestration of large symptomatic macrocystic SC was not yet described in the literature. In this study, 3 female patients underwent laparoscopic fenestration for macrocystic SC (12-14 cm). Diagnosis was established via magnetic resonance imaging and endoscopic ultrasound, with intra-cystic dosage of tumors markers (ACE and CA19-9) in 2 patients. All patients were symptomatic and operated on 15-60 mo after diagnosis. Radiological evaluation showed constant cyst growth. Patients were informed about this new surgical modality that can avoid pancreatic resection. The mean operative time was 103 min (70-150 min) with one conversion. The post-operative course was marked by a grade A pancreatic fistula in one patient and was uneventful in the other two. The hospital stay was 3, 10, and 18 d, respectively. The diagnosis of macrocystic SC was histologically-confirmed in all cases. At the last follow-up (13-26 mo), all patients were symptom-free, and radiological evaluation showed complete disappearance of the cyst. Laparoscopic fenestration, as opposed to resection, should be considered for large symptomatic macrocystic SC, thereby avoiding pancreatic resection morbidity and mortality.

    Mucinous cystadenoma of the appendix is a rare condition and represents one of the three entities with the common name mucocele of the appendix. It is characterized by a cystic dilatation of the lumen with stasis of mucus inside it. Histopathologically mucocele is divided into three groups: focal or diffuse mucosal hyperplasia, mucinous cystadenoma and mucinous cystadenocarcinoma. This condition is often associated with other neoplasia, especially adenocarcinoma of the colon and ovaries. We here describe a 57 year old male patient who presented with abdominal discomfort, constipation, fresh blood in stool and frequent urination. He had a big cystadenoma of the appendix associated with adenocarcinoma of the colon and hepatocellular carcinoma of the liver. The patient underwent right haemicolectomy, sigmoid colon resection and segmental resection of the liver. Now 3 years later he has no evidence of disease relapse. According to this, we stress the need of accurate preoperative diagnosis and intraoperative exploration of the whole abdomen in these patients. PMID:16610012

    A 13-year-old domestic shorthair cat was presented with weight loss and azotemia. Abdominal ultrasound revealed a large cystic space- occupying lesion with multiple septae in the left kidney. A core needle biopsy yielded a renal cystadenoma originating from the epithelial cells. This report describes the clinical, ultrasonographic and computed tomographic features and the growth progression of a renal cystadenoma. We describe the first attempt to apply the human Bosniak classification to a cat with renal cystic neoplasia to differentiate between benign and malignant lesions. Cystadenoma should be a differential diagnosis in cases of renal cystic space-occupying lesions. Other differentials, imaging features to differentiate benign and malignant lesions and the risk of malignant transformation will be discussed.

    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.

    Full Text Available Abstract Introduction Mucinous cystadenoma is a type of mucocele of the appendix that is rarely encountered in clinical practice. Dogmatic consensus on the optimal surgical modus operandi of appendicular mucocele is lacking in the literature and this remains a subject of controversy. There is little agreement with regard to the best procedure (right hemicolectomy versus appendectomy or the best surgical approach (laparoscopic versus laparotomy. Case presentation We report the case of a 70-year-old Asian woman from Karachi who presented with pain in the right iliac fossa for 15 days. On physical examination, a mobile and firm mass was palpable in the right iliac fossa. A colonoscopy was performed which showed external compression of the cecum. A biopsy of the mucosa was normal. Computed tomography scan showed a mucocele of the appendix with minimal periappendiceal fat stranding. She underwent an initial diagnostic laparoscopy to evaluate any mucin spillage in the peritoneal cavity. Once no spillage was identified, an open appendectomy was then performed. Intra-operatively, a frozen section of the appendiceal sample was sent to ascertain the need for an extension of surgery to a right hemicolectomy. Absence of any malignancy on the frozen section obviated the need for a surgical extension. The final histopathological examination showed a mucinous cystadenoma of the appendix. The patient was symptom-free at one year after surgery. Conclusion It is important to distinguish between mucinous cystadenomas and mucinous cystadenocarcinomas. However, this distinction remains elusive in the pre-operative setting. A simple appendectomy using an intra-operative frozen section appears to be a reasonable surgical approach for selected cases with an intact mucocele of the appendix. However, long-term follow-up is warranted in such patients to evaluate the risks of using this approach.

    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

  3. Role of BRCA1 in Controlling Mitotic Arrest in Ovarian Cystadenoma Cells

    Cancers that develop in BRCA1 mutation carriers are usually near tetraploid/polyploid. This led us to hypothesize that BRCA1 controls the mitotic checkpoint complex, as loss of such control could lead to mitotic errors resulting in tetraploidy/polyploidy with subsequent aneuploidy. We used an in vitro system mimicking pre-malignant conditions, consisting of cell strains derived from the benign counterparts of serous ovarian carcinomas (cystadenomas) and expressing SV40 large T antigen, conferring the equivalent of a p53 mutation. We previously showed that such cells undergo one or several doublings of their DNA content as they age in culture and approach the phenomenon of in vitro crisis. Here we show that such increase in DNA content reflects a cell cycle arrest possibly at the anaphase promoting complex, as evidenced by decreased BrdU incorporation and increased expression of the mitotic checkpoint complex. Down-regulation of BRCA1 in cells undergoing crisis leads to activation of the anaphase promoting complex and resumption of growth kinetics similar to those seen in cells before they reach crisis. Cells recovering from crisis after BRCA1 down-regulation become multinucleated, suggesting that reduced BRCA1 expression may lead to initiation of a new cell cycle without completion of cytokinesis. This is the first demonstration that BRCA1 controls a physiological arrest at the M phase apart from its established role in DNA damage response, a role that could represent an important mechanism for acquisition of aneuploidy during tumor development. This may be particularly relevant to cancers that have a near tetraploid/polyploid number of chromosomes. PMID:21792894

    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.

    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.).

    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)

    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.

    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

    To evaluate the washout (WO) pattern of serous cystadenomas (SCAs) compared with endocrine tumors (ETs) and intraductal papillary mucinous neoplasm (IPMN). Patients with serous cystadenoma (n = 12), ET (n = 29), and IPMN (n = 35) underwent 4-phase computed tomography CT. Tumors were categorized as hyperdense or hypodense. Computed tomographic values measured were unenhanced attenuation (AU), pancreatic attenuation (A12, 12 seconds), portal attenuation (A35), and equilibrium (A158). Computed tomographic parameters calculated were wash-in (WI) = A12 - AU; WO = A12 - A35; and washout ratio (WOR) = WO/WI × 100/22. Hyperdense SCAs had significantly higher WOR than did hyperdense ETs (P = 0.001). Among the 3 hypodense tumors, SCAs had the significantly highest WOR (P < 0.05/3). Relative to the pancreas, the WOR of SCAs were equivalent, whereas the WOR of ETs and IPMNs were significantly lower. Hyperdense SCAs had significantly higher WOR than did hyperdense ETs, and hypodense SCAs had the significantly highest WOR among the three.

    Giant multilocular prostatic cystadenomas (GMPC) are very rare benign tumors that originate from the prostate with extensive spread into the pelvis. The lesion may present as large abdominal mass causing obstructive voiding dysfunction and usually not invading adjacent structures. All of the previously reported patients with GMPC underwent open surgery. Although the natural history of prostatic cystadenoma remains unknown, complete surgical excision may not always be necessary. We report the case of a 74-year-old male who presented a retrovesical recurrence of prostatic cystoadenoma after 16 years, treated with a laparoscopic approach. To our knowledge this is the first case of laparoscopic management of GMPC. In this article we review the current literature about this rare tumor and discuss the diagnostic and management dilemmas posed by this rare pathologic condition. We believe that physicians should at least be aware of the existence of this disease in the differential diagnosis of pelvic cavity tumours and, considering the benignity of GMPC, they should propose--as first--a minimally invasive approach.

    Purpose. To report the clinical features and CT manifestations of giant pancreatic serous cystadenoma (≥10 cm). Methods. We retrospectively reviewed the clinical features and CT findings of 6 cases of this entity. Results. All 6 patients were symptomatic. The tumors were 10.2 cm–16.5 cm (median value, 13.0 cm). CT imaging revealed that all 6 cases showed microcystic appearances (n = 5) or mixed microcystic and macrocystic appearances (n = 1). Five patients with tumors at the distal end of the pancreas received distal pancreatectomy. Among these 5 patients, 2 patients underwent partial transverse colon resection or omentum resection due to close adhesion. One patient whose tumor was located in the pancreatic head underwent pancreaticoduodenectomy; however, due to encasement of the portal and superior mesenteric veins, the tumor was incompletely resected. One patient had abundant draining veins on the tumor surface and suffered large blood loss (700 mL). After 6–49 months of follow-up the 6 patients showed no tumor recurrence or signs of malignant transformation. Conclusions. Giant pancreatic serous cystadenoma necessitates surgical resection due to large size, symptoms, uncertain diagnosis, and adjacent organ compression. The relationship between the tumors and the neighboring organs needs to be carefully assessed before operation on CT image. PMID:27610132

    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.

    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.)

    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.

    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.

    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.

    Full Text Available Abstract Introduction Ectopic ovarian tissue is an unusual entity, especially if it is an isolated finding thought to be of embryological origin. Case presentation An 11-year-old, morbidly obese female presented with left flank pain, nausea, and irregular menses. Various diagnostic procedures suggested a large ovarian cyst, and surgical resection was performed. Conclusion Histologically, the resected mass was not of tubal origin as suspected, but a serous cystadenoma arising from ovarian tissue. The patient's two normal, eutopic ovaries were completely uninvolved and unaffected. A tumor arising from ectopic ovarian tissue of embryological origin seems the most likely explanation. We suggest refining the descriptive nomenclature so as to more precisely characterize the various presentations of ovarian ectopia.

    Full Text Available This is the first report of a primary mucinous cystadenoma (MCA arising from behind the posterior peritoneum of the descending colon in a paediatric patient. A large intra-abdominal cystic lesion was found incidentally during renal ultrasonography in a 14-year-old girl. Imaging studies showed a 13 × 9 × 15 cm homogeneous cystic lesion with mild contrast enhancement of the wall. The cyst appeared to originate from the retroperitoneum, but was separated from the left kidney, ovary, and pancreas. At laparotomy, there was a cyst behind the posterior peritoneum of the descending colon. The cyst was successfully excised, and histopathology showed MCA. Although primary MCA in the retroperitoneum is extremely rare in children, it should be considered in the differential diagnosis of an intra-abdominal cyst, since it needs to be excised to eliminate the risk of infection, recurrence, and malignancy.

    Digital papillary carcinoma (DPC) is a rare, underreported, and often misdiagnosed malignant tumor of the sweat glands. It is often located on the digits and toes and most commonly occurs in male individuals in their fifties to seventies. Because of lack of pain, slow growth, and an inconspicuous appearance, clinical diagnosis is often missed or delayed. In contrast, apocrine hidrocystoma (AH) is a cystic adenoma that arises from the apocrine secretory coil, and it is extremely rare for AHs to develop on the digits. We report 7 cases of DPC, including clinical course, histopathologic and immunohistochemical findings, and therapeutic approach in which the initial histopathologic diagnosis in all cases was AH or cystadenoma. However, complete excision of the neoplasms led to a final diagnosis of DPC. After an adequate treatment, no recurrence or metastasis was found in any of the cases described. All the cases studied showed similar histopathologic and immunohistochemical findings. The initial incisional biopsy showed large unilocular or multilocular cystic spaces situated within the dermis, lined by a double layer of epithelial cells with tiny papillary structures. No cellular atypia, necrosis, or pleomorphism was observed. However, complete excision revealed neoplastic lesions involving the dermis and/or subcutis, with an infiltrative pattern and papillary projections into luminal spaces. Immunoperoxidase studies showed positivity for CK7, S-100 protein, CEA, p63, smooth muscle actin, and calponin. DPC is a rare but life-threatening malignancy, therefore it is important to be able to identify such a lesion both clinically and histopathologically, treat it, and monitor the patient for the tumor's potential recurrence and metastasis. Pathologists and dermatopathologists should be aware that a histopathologic diagnosis of AH or cystadenoma on the fingers and toes should be established with caution, because probably those lesions represent the superficial and cystic

    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

    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.

    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

    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.

    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.

    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.

    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).

    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.

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.

    Background Mucoceles resulting from cystadenomas of the appendix are uncommon. Although rare, rupture of the mucoceles can occur with or without causing any abdominal complaint. There are several reports associating colonic malignancy with cystadenomas of the appendix. Herein, we report an unusual and interesting case of right inguinal hernia associated with left colon cancer. Case presentation A case of ruptured mucocele resulting from cystadenoma of the appendix was presented as right inguinal hernia in a 70-year-old male. The patient underwent colonoscopy, x-ray, ultrasound and computed tomography. Localized pseudomyxoma peritonei associated with adenocarcinoma of the descending colon was diagnosed. The patient underwent segmental resection of the colon, appendectomy, debridement of pseudomyxoma and closure of the internal ring of right inguinal canal. He is free of symptoms in one year follow-up. Conclusion Synchronous colon cancer may occur in patients with appendiceal mucoceles. In such patients, the colon should be investigated and colonoscopy can be performed meticulously in cases of ruptured mucoceles and localized pseudomyxoma peritonei. Surgical intervention is the current choice of management. PMID:17074081

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

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

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

    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.

    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.

    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.

    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.

    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.

    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.

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

    2016-01-01

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

    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.

  16. Concurrent biliary drainage and portal vein embolization in preparation for extended hepatectomy in patients with biliary cancer

    BACKGROUND: Patients with perihilar cholangiocarcinoma and gallbladder cancer extending into the hilum often present with jaundice and a small future liver remnant (FLR). If resectable, preoperative biliary drainage and portal vein embolization (PVE) are indicated. Classically, these measures have...... been performed sequentially, separated by 4-6 weeks. PURPOSE: To report on a new regime where percutaneous transhepatic biliary drainage (PTBD) and PVE are performed simultaneously, shortening the preoperative process. MATERIAL AND METHODS: Six patients were treated with concurrent PTBD and PVE under...

    Full Text Available Abstract Introduction Hydatid disease of the soft tissue is an exceedingly uncommon site to be affected by the tapeworm Echinococcus. The presentation is often vague and misleading. The diagnostic armamentarium has to be supplemented by a meticulously taken history and clinical examination. Case presentation The present case report describes a 33-year-old Saudi male with a painless swelling in the right buttock which turned out to be a primary hydatid disease of the soft tissue. The lump was successfully excised surgically and the patient had an uneventful discharge. Conclusion Surgical excision of the extrahepatic hydatid disease remains the mainstay of treatment; although medical treatment is available for the recurrent and disseminated disease.

    Although hepatitis B virus (HBV) primarily affects hepatocytes, it has also been shown to cause complications in the skin, joints, muscles, and kidneys. Thyroid dysfunction is uncommon in cases of acute HBV infection. In this report, we describe a case of a 46-year-old woman with incipient acute hepatitis B virus (HBV) infection who presented clinically with Graves' hyperthyroidism. She showed typical symptoms of hyperthyroidism, and laboratory tests revealed high levels of HBV DNA and alanine transaminase (ALT). The patient was not administered with antithyroid medicine or radioiodine, but she was given antiviral therapy and symptomatic treatment with propranolol. Follow-up studies showed that as the HBV DNA levels decreased, the thyroid function recovered. Graves' disease maybe an extrahepatic manifestation of acute HBV infection. Antiviral therapy is likely to be beneficial for this condition as without severe thyrotoxicosis.

    An extrahepatic arterioportal fistula (APF) involving the gastroduodenal artery and superior mesenteric vein is rare and mostly results from iatrogenic injuries. The clinical symptoms associated with APFs may include abdominal pain, gastrointestinal bleeding, ascites, nausea, vomiting, diarrhea, or even congestive heart failure. We present the case of a 70-year-old man who presented with chronic abdominal pain and gastrointestinal bleeding secondary to APF and portal vein thrombosis. The endovascular embolization of APF was accomplished successfully, and symptoms of portal hypertension resolved immediately after intervention. Unfortunately, the patient did not respond well to anticoagulation therapy with warfarin. Therefore, the patient underwent implantation of a transjugular intrahepatic portosystemic shunt, and the complications of portal hypertension resolved. In conclusion, the embolization of APF is technically feasible and effective and can be considered the first-choice therapy in selected patients.

    The relative significance of local proliferation and extrahepatic recruitment of Kupffer cells was investigated by partial-body irradiation before the induction of macrophage hyperplasia by zymosan. There was no difference in growth of the Kupffer cells population between nonirradiated rats and rats irradiated with the liver shielded, whereas irradiation of the liver with the rest of the body (bone marrow) shielded resulted in strong inhibition of growth (-61%). Splenectomy combined with bone marrow irradiation inhibited growth to a lesser extent as compared to liver irradiation (-38%). Monocyte and other leukocyte numbers were strongly reduced in peripheral blood and their accumulation in the liver was completely prevented by bone marrow irradiation. Our results demonstrate that local proliferation of resident Kupffer cells represents the predominant source for their increased number during hyperplasia.
