    The primary biliary carcinoma is usually unresectable at presentation, because of early lymphatic spread. To determine the incidence and the spread pattern of lymph node metastases according to the location of the primary tumor, we analyzed the CT scans of the patients with primary biliary adenocarcinoma. We reviewed the CT scans of 92 patients with pathologically proven primary biliary adenocacinima, including 45 peripheral cholangiocarcinomas, 22 hilar cholangiocarcinomas, 18 gallbladder carcinomas, and 7 common bile duct carcinomas. Positive adenopathy was diagnosed when the node exceeded 10 mm in short axis. The overall incidence of nodal metastases was 59.8% (55/92); 66.7% in peripheral cholangiocarcinoma, 54.5% in hilar cholangiocarcinoma, 55.6% in gallbladder carcinoma, and 42.9% in common bile duct carcinoma. The most commonly involved nodal group was the lesser omentum, followed by the celiac, periaortic, and peripancreatic group. The phrenic node group was only involved in the cases with the peripheral or hilar cholangiocarcinoma. The primary biliary carcinoma has a high incidence of lymph node metastases at the time of diagnosis, and shows different nodal spread pattern according to the location of the primary tumor. Involvement of the phrenic node was limited to the peripheral and hilar cholangiocarcinoma

    A retrospective study is reported, carried out on 45 patients with primary carcinoma of biliary tree. The purpose of the study was to test the effectiveness of US in accurately demonstrating the kind of jaundice (diagnostic level I), the site (diagnostic level II) and etiology of the biliary obstruction (diagnostic level III). A carcinoma of the gallbladder with common bile duct infiltration was found in 23 patients, while 22 were affected by primary bile carcinoma. In the 23 patients with carcinoma of the gallbladder, the kind of jaundice was correctly diagnosed in 100% of cases while the site and cause of obstruction were detected in 18 (78%) and 10 (43%) cases respectively. In the 22 cases of primary bile duct carcinoma, the kind of jaundice was accurately demonstrated in 21 cases (95%); the site and etiology of obstruction in 19 (86%) and 11 (50%) patients respectively. Therefore, in a total number of 45 patients examined, success rate was 98% in diagnostic level I, 80% in diagnostic level II, and 47% in diagnostic level III. Ultrasonography proves thus to be almost completely reliable in diagnostic level I, and very reliable in diagnostic in diagnostic level II; so much so that it can, alone, direct the surgeon in case of an emergency. Results are less satisfactory in diagnostic level III. Therefore, if details of the obstuctive lesion and the biliary tree are required for the planning of definite treatment, either PTC, ERCP, or CT should be performed

    Primary carcinoma of the duodenum represents about 0.35% of all gastrointestinal carcinomas and is thus a rare disease. The radiological diagnosis of a duodenal origin is made more difficult by the close proximity of the pancreas, biliary system, right kidney and transverse colon. Histologically, duodenal malignant tumours are usually adenocarcinomas. Between 1973 and 1983, eight patients with primary duodenal carcinomas were diagnosed at the University of Tuebingen. Average age of the patients was 67 years. There was no sex difference. Average survival was 3.3 years. (orig.) [de

    AIM: To compare the difference of expression of Bcl-2 and Bax in extrahepatic biliary tract carcinoma and dysplasia, and to analyze the role of Bcl-2 and Bax proteins in the progression from dysplasia to carcinoma and to evaluate the correlation of Bcl-2/Bax protein expression with the biological behaviors. METHODS: Expressions of Bcl-2 and Bax were examined immunohistochemically in 27 cases of extrahepatic biliary tract carcinomas (bile duct carcinoma: n = 21, carcinoma of ampulla of Vater: n = 6), and 10 cases of atypical dysplasia. Five cases of normal biliary epithelial tissues were used as controls. A semiquantitative scoring system was used to assess the Bcl-2 and Bax reactivity. RESULTS: The expression of Bcl-2 was observed in 10 out of 27 (37.0%) invasive carcinomas, 1 out of 10 dysplasias, none out of 5 normal epithelial tissues. Bax expression rate was 74.1% (20/27) in invasive carcinoma, 30% (3/10) in dysplasia, and 40% (2/5) in normal biliary epithelium. Bcl-2 and Bax activities were more intense in carcinoma than in dysplasia, with no significant difference in Bcl-2 expression (P = 0.110), and significant difference in Bax expression (P = 0.038). Level of Bax expression was higher in invasive carcinoma than in dysplasia and normal tissue (P = 0.012). Bcl-2 expression was correlated to Bax expression (P = 0.0059). However, Bcl-2/Bax expression had no correlation with histological subtype, grade of differentiation, or level of invasion. CONCLUSION: Increased Bcl-2/Bax expression from dysplasia to invasive tumors supports the view that this is the usual route for the development of extrahepatic biliary tract carcinoma. Bcl-2/Bax may be involved, at least in part, in the apoptotic activity in extrahepatic biliary carcinoma. PMID:14606101

    Fourteen patients with carcinomas of the gallbladder and eight patients with biliary duct carcinomas were examined by CT, sonography, percutaneous transhepatic cholangiography (PTC), endoscopic retrograde cholangiography (ERC) and angiography. The results were compared retrospectively. Sonography proved suitable as a screening method. For accurate demonstration, this should be supplemented by C.T.. PTC and ERC demonstrate intraductal extension of biliary carcinomas and of gallbladder carcinomas infiltrating the bile ducts. The value of angiography consists merely in the pre-operative demonstration of the vascular anatomy. (orig.) [de

    Full Text Available Background. The study aims to analyze in detail the incidence, mortality using the standardized incidence ratio (SIR, and standardized mortality ratio (SMR of hepatocellular carcinoma (HCC in primary biliary cirrhosis (PBC, because no large case studies have focused on the detailed statistical analysis of them in Asia. Methods. The study cohorts were consecutively diagnosed at Gunma University and its affiliated hospitals. Age- or sex-specific annual cancer incidence and deaths were obtained from Japanese Cancer Registry and Death Registry as a reference for the comparison of SIR or SMR of HCC. Moreover, univariate analyses and multivariate analyses were performed to clarify predictive factors for the incidence of HCC. Results. The overall 179 patients were followed up for a median of 97 months. HCC had developed in 13 cases. SIR for HCC was 11.6 (95% confidence interval (CI, 6.2–19.8 and SMR for HCC was 11.2 (95% CI, 5.4–20.6 in overall patients. The serum albumin levels were a predictive factor for the incidence of HCC in overall patients. Conclusions. The incidence and mortality of HCC in PBC patients were significantly higher than those in Japanese general population. PBC patients with low serum albumin levels were populations at high risk for HCC.

    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.

    Full Text Available We report a rare case of hepatocellular carcinoma in native liver in a case of biliary atresia. The patient was a 38-year-old female with three children who had an aggressive tumor, resulting in her subsequent death. We also review 14 reports, published previously in the English language medical literature, concerning hepatocellular carcinoma originating from native liver in biliary atresia cases and discuss the possible etiology, and propose more careful follow up for the patients with biliary atresia who suffer from repetitive cholangitis and/or experience the child delivery.

    Full Text Available Manan A Jhaveri, Kris V Kowdley Liver Care Network, Swedish Medical Center, Seattle, WA, USA Abstract: Primary biliary cholangitis (PBC is a chronic autoimmune cholestatic liver disease that predominantly affects women in early to middle age. It is typically associated with autoantibodies to mitochondrial antigens and results in immune-mediated destruction of small and medium-sized intrahepatic bile ducts leading to cholestasis, hepatic fibrosis and may progress to cirrhosis or hepatic failure and, in some cases, hepatocellular carcinoma. The clinical presentation and the natural history of PBC have improved over the years due to recognition of earlier widespread use of ursodeoxycholic acid (UDCA; about one-third of patients show suboptimal biochemical response to UDCA with poor prognosis. Until recently, UDCA was the only US Food and Drug Administration approved agent for this disease for more than two decades; obeticholic acid was approved in 2016 for treatment of patients with PBC with a suboptimal response or intolerance to UDCA. Currently, liver transplantation is the most effective treatment modality for PBC patients with end-stage liver disease. This review will focus on the recent advances in therapy of primary biliary cholangitis, with emphasis on obeticholic acid.

    From February 1980 through September 1990, 92 patients with obstructive jaundice resulting from biliary tract cancer were registered at Shikoku Cancer Center Hospital or Ehime University Hospital. Radiation therapy (RT) was used to treat 38 of these patients (30 with carcinoma of the extrahepatic bile duct, excluding ampulla of Vater, and eight patients with carcinoma of the gallbladder). Of 38 patients, 11 underwent intraoperative radiation therapy (IORT), and 27 were treated by external radiation therapy (ERT) alone. In contrast, 54 patients (39 with carcinoma of the extrahepatic bile duct and eight with carcinoma of the gallbladder) were not treated by RT. All jaundiced patients received external and/or internal biliary drainage of some kind. Among patients undergoing biliary drainage with a catheter, 21 patients who underwent RT (four with IORT) survived significantly longer than 19 patients who did not (generalized Wilcoxon test: p<0.05). There were no significant differences in survival between 7 patients with recanalization and 11 patients with no recanalization. Concerning the survival of laparotomized patients, excluding those with complete resection or perioperative death, eight patients treated with postoperative ERT survived longer than 12 patients who did not have postoperative ERT (not significant). Eleven patients underwent IORT. A patient with unresectable carcinoma of the hilar bile duct survived 2 years and 3 months after a combination treatment of ERT and IOTR. In four of eight autopsied patients, radiation effects of Grade II were observed (Oboshi and Shimosato's evaluation system for the histological effects of radiation therapy). Our experience suggests that RT is effective in patients with obstructive jaundice caused by carcinoma of the biliary system. (author)

    Endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy is a well-established procedure for the treatment of bile duct strictures. However, the procedure is difficult to perform in patients with intradiverticular papillae or tumor infiltration of the major papilla. Percutaneous transhepatic biliary stenting (PTBS) is commonly used in the management of malignant biliary stricture. The current study reports two cases of PTBS performed to treat malignant obstructive jaundice caused by ampullary carcinoma complicated with intradiverticular papillae. PTBS is potentially a safe technique for this relatively rare condition.

    BACKGROUND: Several case reports, but only a few studies, have examined the coexistence of coeliac disease and primary biliary cirrhosis. AIM: To estimate the risk of primary biliary cirrhosis in two national cohorts of patients with coeliac disease in Denmark and Sweden. METHODS: Through record...... linkage all Danish patients hospitalised with coeliac disease were followed for possible occurrence of primary biliary cirrhosis from 1 January 1977 until 31 December 1992. All patients hospitalised with coeliac disease in Sweden from 1987 to 1996 were also followed in a separate analysis. RESULTS......: A total of 896 patients with coeliac disease were identified in Denmark with a median follow up period of 9.1 years for a total of 8040 person-years at risk. Two cases of primary biliary cirrhosis were observed where 0.07 were expected, giving a standardised incidence ratio of 27.6 (95% confidence...

    {sup 99m}Tc-Sulfur Colloid is concentrated in Kupffer cells of the liver, whereas the new biliary agents such as {sup 99m}Tc-HIDA are processed by hepatic parenchymal cells. The distant metastatic lesions in skull and lung of the primary hepatocellular carcinoma in 38-year old Korean male were detected with {sup 99m}Tc-HIDA scintigraphy. The chest PA, skull bone X-ray and radionuclide scintigraphic studies are illustrated. This observation suggests that {sup 99m}Tc-HIDA scintigraphy is useful for detection of distant metastases of primary hepatocellular carcinoma.

    Ursodeoxycholic acid is administered to patients with primary biliary cirrhosis, a chronic progressive inflammatory autoimmune-mediated liver disease with unknown aetiology. Despite its controversial effects, the U.S. Food and Drug Administration has approved its usage for primary biliary cirrhosis. To assess the beneficial and harmful effects of ursodeoxycholic acid in patients with primary biliary cirrhosis. We searched for eligible randomised trials in The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, Science Citation Index Expanded, LILACS, Clinicaltrials.gov, and the WHO International Clinical Trials Registry Platform. The literature search was performed until January 2012. Randomised clinical trials assessing the beneficial and harmful effects of ursodeoxycholic acid versus placebo or 'no intervention' in patients with primary biliary cirrhosis. Two authors independently extracted data. Continuous data were analysed using mean difference (MD) and standardised mean difference (SMD). Dichotomous data were analysed using risk ratio (RR). Meta-analyses were conducted using both a random-effects model and a fixed-effect model, with 95% confidence intervals (CI). Random-effects model meta-regression was used to assess the effects of covariates across the trials. Trial sequential analysis was used to assess risk of random errors (play of chance). Risks of bias (systematic error) in the included trials were assessed according to Cochrane methodology bias domains. Sixteen randomised clinical trials with 1447 patients with primary biliary cirrhosis were included. One trial had low risk of bias, and the remaining fifteen had high risk of bias. Fourteen trials compared ursodeoxycholic acid with placebo and two trials compared ursodeoxycholic acid with 'no intervention'. The percentage of patients with advanced primary biliary cirrhosis at baseline varied

    Primary biliary cirrhosis is associated with other autoimmune diseases including Sjögren's syndrome, and scleroderma. Esophageal dysmotility is well known in scleroderma, and Sjögren's syndrome. The aim of this study is to investigate whether any esophageal motor dysfunction exists in patients with primary biliary cirrhosis. The study was performed in 37 patients (36 women, mean age: 56.29 ± 10.01 years) who met diagnostic criteria for primary biliary cirrhosis. Thirty-seven functional dyspepsia patients, were also included as a control group. Patients entering the study were asked to complete a symptom questionnaire. Distal esophageal contraction amplitude, and lower esophageal sphincter resting pressure were assessed. Manometric findings in primary biliary cirrhosis patients vs. controls were as follows: Median lower esophageal sphincter resting pressure (mmHg): (24 vs 20, p=0.033); median esophageal contraction amplitude (mmHg): (71 vs 56, p=0.050); mean lower esophageal sphincter relaxation duration (sc, x ± SD): (6.10 ± 1.18 vs 8.29 ± 1.92, pesophageal sphincter relaxation (%) (96 vs 98, p=0.019); respectively. No significant differences were evident in median peak velocity (sc) (3.20 vs 3.02, p=0.778) between patients with primary biliary cirrhosis and the functional dyspepsia patients. Esophageal dysmotility was found in 17 (45.9%) primary biliary cirrhosis patients (non-specific esophageal motor disorder in ten patients, hypomotility of esophagus in five patients, nutcracker esophagus in one patient and hypertensive lower esophageal sphincter in one patient). Esophageal dysmotility was detected in 45.9% of patients. The study suggests that subclinic esophageal dysmotility is frequent in patients with primary biliary cirrhosis. Crown Copyright © 2014.

    The patient is a previously healthy 52-year-old woman who presented with dyspepsia for two months. Multiple imaging modalities including ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) showed diffuse bile duct dilatation with an obstructive lesion of the distal extrahepatic biliary duct (EHD) as well as two masses in the peripancreatic area. The peripancreatic masses appeared cystic with posterior acoustic enhancement on ultrasound, low density on CT imaging, and high signal intensity on T2-weighted MRI. The lesion in the distal EHD exhibited similar characteristics on CT and MRI. A Whipple procedure was performed and histological specimens showed malignant cells with large mucin pools that was consistent with a diagnosis of colloid carcinoma of the EHD with metastatic lymphadenopathies. Colloid carcinoma, also called mucinous carcinoma, is classified as a histologic variant of adenocarcinoma. Because the colloid carcinoma of the biliary tree is exceedingly rare, the imaging characteristics and the clinical features of colloid carcinoma remain relatively unknown. We report a case of colloid carcinoma of the common bile duct and its accompanied metastatic lymphadenopathies with characteristic imaging findings reflecting abundant intratumoral mucin pools

    We present a case that suggests a relationship between primary biliary cirrhosis and myasthenia gravis. A 43-year-old Japanese woman was admitted to the Nagoya City University Medical School, First Department of Internal Medicine with abnormal liver function in August 1991. She had had ptosis of the right eye since 1990. She had not been treated for liver disease. Ptosis of the right eye and hepatomegaly were present. Serum laboratory examinations revealed elevated biliary enzymes and IgM levels; tests were positive for antimitochondrial antibody and antiacetylcholine antibody. Liver histology revealed chronic non-suppurative destructive cholangitis and led to a diagnosis of primary biliary cirrhosis. The tensilon test was positive. Electromyography with repetitive motor nerve stimulation revealed a neuromuscular junction defect; i.e., the primary characteristic of myasthenia gravis. The patient was diagnosed with myasthenia gravis. Although the development of myasthenia gravis has previously been reported in patients with primary biliary cirrhosis during D-penicillamine administration, this is a very rare case of the coexistence of both diseases before such treatment.

    Background Primary Biliary Cirrhosis is a cholestatic liver disease characterized by immune-mediated destruction of bile ducts. Its pathogenesis is largely unknown, although complex interactions between environment and genetic predisposition are proposed. Aims Identify disease risk factors using a detailed patient questionnaire and compare study findings to 3 published reports. Methods Questionnaire data were prospectively collected from 522 cases and 616 controls of the Mayo Clinic Primary Biliary Cirrhosis Genetic Epidemiology Registry. Case and control responses were compared using logistic regression, adjusting for recruitment age, sex, and education level. Results Cases reported ever regularly smoking cigarettes more frequently than controls (P < 0.001). History of urinary tract infection (UTI) was similar between groups; however, cases reported multiple UTIs more commonly than controls (P < 0.001). Frequency of other autoimmune disease was higher in cases than controls (P < 0.001). As well, prevalence of primary biliary cirrhosis among first-degree relatives was higher in case families than control families (P < 0.001). Conclusions Our study confirms prior reported risk factors associated with disease risk. Given the potential importance of gene and environment interactions, further examination of environmental risk factors considering genetic background may provide new insight into primary biliary cirrhosis pathogenesis.

    Objective: To analyze the method and short term efficacy of interventional therapy for hilar biliary obstructive jaundice. Methods: 100 consecutive patients with perihilar biliary obstruction admitted before May 2004 were treated with percutaneous transhepatic biliary drainage (PTBD) or placement of metallic stents. Among them, 39 patients were found with bile duct cancer, 6 with adenocarcinoma of gallbladder, 22 with metastatic carcinoma, 15 with primary liver carcinoma and 18 with bile duct strait after liver transplantation. Serum total bilirubin before operation and 3-7 days, 8-14 days after procedure were analysed by t test. Results: 79 patients with PTBD (including simple external drainage and combined internal and external drainage), and 21 patients with stents placement (including 31 stents of 4 different kinds) were all carried out successfully. There were significant differences in serum total bilirubin before and 3-7 days, 8-14 days after the procedure, P<0.05 vs P<0.01. Conclusion: Interventional therapy is simple, safe, and effective for hilar biliary obstruction, the latter showed more significance than the former with short term satisfaction. (authors)

    Purpose: To evaluate the therapeutic effect of percutaneous transhepatic biliary drainage (PTBD) in patients with obstructive jaundice caused by biliary involvement of hepatocellular carcinomas (HCC) and to determine the prognostic factors. Methods: We retrospectively analyzed the data of 22 consecutive patients (M:F = 20:2, mean age 52.8 years).Inclusion criteria were the patient having obstructive jaundice caused by HCC that invaded the bile ducts and having at least 4 weeks of follow-up data after the PTBD. We defined 'good response' and 'poor response' as whether the level of total bilirubin decreased more than 50% in 4 weeks or not. Total bilirubin level (T-bil),Child-Pugh score and the location of biliary obstruction for the two groups were compared. In addition, the interval between clinical onset of jaundice and PTBD, the degree of parenchymal atrophy and the size of the primary tumor were compared. Results: Of the 22 patients, 13 (59.1%) showed good response. T-bil was significantly lower in the good response group than in the poor (14.2 ± 6 mg/dlvs 25.9 ± 13.8 mg/dl, p = .017). In the five patients with T-bil 20 mg/dl, only three (33%)showed good response. Although statistically not significant, patients with Child score <10 showed better results [good response rate of 66.7% (12/18)] than patients with Child score ?10 [good response rate of 25% (1/4)]. Involvement of secondary confluence of the bile duct also served as a poor prognostic factor (p =0.235). The interval between clinical onset of jaundice and PTBD, the presence of parenchymal atrophy and the size of the tumor did not show significant effect. Conclusion: Early and effective biliary drainage might be necessary in this group of patients with limited hepatic function

    All patients seen with primary biliary cirrhosis during this decade were reviewed. Sixty per cent were diagnosed during the earliest asymptomatic stage of this illness and only 20% progressed symptomatically during a mean follow-up period of 52 months. Those patients presenting with persistent jaundice followed a classic downhill course. These data establish the previously predicted trend toward earlier diagnosis and raise questions about the concept of universal progression of this disease and its time course.

    Patients with advanced hepatocellular carcinoma (HCC) with jaundice have an extremely poor prognosis. Although biliary drainage can resolve obstructive jaundice, signs of obstruction may not be evident. This study evaluated the role of endoscopic biliary drainage in patients with advanced HCC and obstructive jaundice. From 2010 to 2015, 74 patients underwent endoscopic biliary drainage for obstructive jaundice due to advanced HCC. Jaundice resolution was defined as complete response and total bilirubin concentration below 3 mg/dl. The technical success rate in the 74 patients was 92.1% (70/76). Of the 70 patients who underwent successful biliary drainage, 48 (68.6%) and 22 (31.4%) were Child-Pugh classes B and C, respectively, and 10 (14.3%) and 60 (85.7%) were BCLC stages B and C, respectively. Intrahepatic bile duct (IHD) dilatation was observed in 35 patients (50%). After drainage, the complete response rate was 35.7% (25/70). The mean time to resolution was 17.4 ±8.5 days. However, jaundice was re-aggravated in 74.3% (15/25) after a mean 103.5 ±96.4 days. Multivariate analysis showed that the absence of ascites, presence of IHD dilatation, normal range of prothrombin time, and lower MELD score were significantly associated with complete response. The overall survival rate was 15.7% (11/70) and the median survival time is 28 days (95% confidence interval 2.6-563 days). Complete response and HCC treatment after drainage were significantly associated with survival. Effective endoscopic biliary drainage is an important palliative treatment in patients with advanced HCC and obstructive jaundice, especially those with IHD dilatation and preserved liver function, as determined by ascites, prothrombin time, and MELD score.

    Secreted protein acidic and rich in cysteine (SPARC) is a matricellular protein that influences chemotherapy effectiveness and prognosis. The aim of this study was to investigate whether SPARC expression correlates with the postoperative survival of patients treated with surgical resection for biliary carcinoma. SPARC expression in resected biliary carcinoma specimens was investigated immunohistochemically in 175 patients. The relationship between SPARC expression and prognosis after surgery was evaluated using univariate and multivariate analyses. High SPARC expression in peritumoral stroma was found in 61 (35%) patients. In all patients, stromal SPARC expression was significantly associated with overall survival (OS) (P = 0.006). Multivariate analysis revealed that high stromal SPARC expression was an independent risk factor for poor OS (HR 1.81, P = 0.006). Moreover, high stromal SPARC expression was independently associated with poor prognosis in a subset of 118 patients treated with gemcitabine-based adjuvant chemotherapy (HR 2.04, P = 0.010) but not in the 57 patients who did not receive adjuvant chemotherapy (P = 0.21). Stromal SPARC expression correlated with the prognosis of patients with resectable biliary carcinoma, and its significance was enhanced in patients treated with adjuvant gemcitabine-based chemotherapy.

    Full Text Available The association between celiac disease and primary biliary cirrhosis has been described in several case reports and small screening studies, with varying prevalence rates. Stored sera from 378 patients with primary biliary cirrhosis were tested for immunoglobulin (Ig A endomysium and tissue transglutaminase antibodies. Ten patients were positive for both antibodies (2.6%; five of these patients had had small bowel biopsies confirming celiac disease. A further 44 patients (11.6% had raised titres of IgA tissue transglutaminase antibody but were negative for IgA endomysium antibody. The increased prevalence of celiac-related antibodies in patients with primary biliary cirrhosis suggests that the two conditions are associated, although the reason for the association remains unclear. Patients with primary biliary cirrhosis should be considered to be at high risk for celiac disease. Although liver biochemistry does not improve when these patients are fed a gluten-free diet, the complications of untreated celiac disease warrant the identification and treatment of the condition in this population.

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

    Serum antinuclear antibodies giving the 'multiple nuclear dots' or the 'rim-like/membranous' patterns are frequently detected by indirect immunofluorescence on HEp-2 cells in patients with primary biliary cirrhosis. To assess the accuracy of multiple nuclear dot and rim-like/membranous antinuclear antibodies for the diagnosis of primary biliary cirrhosis. Sera from 4371 consecutive patients referred to our laboratory were analysed under code for antinuclear antibodies testing by indirect immunofluorescence on HEp-2 cells. Review of the clinical records of the 4371 patients allowed identification of 101 patients with antimitochondrial antibody-positive primary biliary cirrhosis and 22 with antimitochondrial antibody-negative variant. Multiple nuclear dot and/or rim-like/membranous patterns were found in 59 (1.3%) of the 4371 patients: 31 antimitochondrial antibody-positive primary biliary cirrhosis, 17 antimitochondrial antibody-negative primary biliary cirrhosis and 11 non-primary biliary cirrhosis. The specificity for primary biliary cirrhosis of both the antinuclear antibodies pattern was 99%. Positive predictive value and likelihood ratio for a positive test were 86% (95% CI: 72.7-94) and 221 (95% CI: 91.7-544) for multiple nuclear dot, 79% (95% CI: 62.2-90.1) and 132 (95% CI: 56.8-312.7) for rim-like/membranous, respectively. Multiple nuclear dot and rim-like/membranous antinuclear antibodies are rare findings. Their positivity strongly suggests the diagnosis of primary biliary cirrhosis, irrespective of antimitochondrial antibody status. The high specificity for primary biliary cirrhosis makes them a useful diagnostic tool especially in antimitochondrial antibody-negative patients.

    Liver cirrhosis and primary carcinoma of the liver were investigated in 1699 autopsies of atomic bomb survivors carried out in Hiroshima from 1956 to 1980. Liver cirrhosis, hepatocellular carcinoma and intrahepatic biliary carcinoma were observed in 116, 111, and 17 cases respectively, the ratios of man to woman and were 2.3, 3.9, and 1.8 with a mean age of 56, 60, and 67 years respectively. There was no evidence that exposure to a-bomb increased the risk of these diseases significantly. About 90% of the hepatocellular carcinomas was combined with liver cirrhosis. Weight of liver and spleen, amount of ascites, hemorrhage from the digestive canals, esophageal varix, combination with other diseases, and histologic correlation with the activities of HBs antigen and ..cap alpha..-fetoprotein were discussed with the relation to the exposure.

    Candidiasis is commonly observed in patients with primary sclerosing cholangitis (PSC), but the clinical risk factors associated with its presence have not been fully investigated. In this study, we aimed to analyse the incidence, risk factors, and transplantation-free survival in primary sclerosing cholangitis (PSC) patients with persistent biliary candidiasis. We retrospectively analysed patients diagnosed with PSC who were admitted to our department during 2002 to 2012. One-hundred fifty patients whose bile cultures were tested for fungal species were selected, and their clinical and laboratory parameters were investigated. The results of endoscopic retrograde cholangiography (ERC) and bile cultures were analysed using chart reviews. The cases of biliary candidiasis were sub-classified as transient or persistent. Thirty out of 150 (20.0%) patients had biliary candidiasis. Although all patients demonstrated comparable baseline characteristics, those with biliary candidiasis showed significantly reduced transplantation-free survival (p candidiasis. A subgroup analysis showed reduced survival with a greater necessity for orthotopic liver transplantation (OLT) only in patients with persistence of Candida (p = 0.007). The survival in the patients with transient biliary candidiasis was comparable to that in candidiasis-free patients. In a multivariate regression analysis that included Mayo risk score (MRS), sex, age, dominant stenosis, inflammatory bowel disease, autoimmune hepatitis overlap syndrome, and number of times ERC was performed, biliary candidiasis was an independent risk factor for reduced survival (p = 0.008). Risk factors associated with acquisition of biliary candidiasis were age at PSC diagnosis and number of ERCs. The persistence of biliary candidiasis is associated with markedly reduced transplantation-free survival in PSC patients. By contrast, actuarial survival in patients with transient biliary candidiasis approaches that for patients without any

    The patency of self-expandable metallic stents (SEMS) is known to be better than plastic stents in the palliation of malignant biliary obstruction. However, data are scarce for obstructive jaundice caused by hepatocellular carcinoma (HCC). This study aimed to compare SEMSs and plastic stents for the palliation of obstructive jaundice in unresectable HCC. A total of 96 patients who underwent endoscopic retrograde biliary drainage with SEMSs or plastic stents were included in this retrospective analysis. The rate of successful biliary drainage, adverse events, stent patency duration, and patient survival were compared between the SEMS (n = 36) and plastic stent (n = 60) groups. The rate of successful biliary drainage was similar between the SEMS and plastic stent groups (25/36 [69.4 %] vs. 39/60 [65.0 %]; P = 0.655). Adverse events occurred in 6 patients (16.7 %) in the SEMS group and 13 patients (21.7 %) in the plastic stent group (P = 0.552). The median patency duration was also similar between the two groups (60 vs. 68 days; P = 0.396). The median patient survival was longer in the plastic stent group than in the SEMS group (123 vs. 48 days; P = 0.005). SEMSs were not superior to plastic stents for the palliation of malignant biliary obstruction in HCC with regard to successful drainage, stent patency, and adverse events. Patient survival was better in the plastic stent group. Given the lower cost, plastic stents could be a favorable option for malignant biliary obstruction caused by HCC. © Georg Thieme Verlag KG Stuttgart · New York.

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

    The treatment of biliary stricture is crucially important for continuing stable chemotherapy for unresectable biliary carcinoma; however, there is no consensus regarding the use of hilar biliary drainage. In this study, we examined the efficacy of endoscopic over 3-branched biliary drainage using self-expandable metallic stents (SEMSs) in patients with unresectable malignant hilar biliary stricture (HBS). A total of 77 patients with unresectable HBS treated with a SEMS and chemotherapy were retrospectively reviewed. There were 59 patients with cholangiocarcinoma and 18 patients with gallbladder carcinoma. The patients were divided into 2 groups (4- or 3-branched group and 2- or 1-branched group) and compared with respect to the duration of stent patency and overall survival. A comparison of the patients' baseline characteristics showed no significant differences between the 4- or 3-branched group and the 2- or 1-branched group. Neither the duration of patency nor survival time exhibited significant differences between the 2 groups, although, among the patients achieving disease control , the duration of patency period and survival time of the 4- or 3-branched group were significantly higher than those observed in the 2- or 1-branched group (P=0.0231 and 0.0466). The use of endoscopic over 3-branched biliary drainage with a SEMS may improve the duration of patency in patients with HBS.

    Primary biliary cirrhosis is a chronic, destructive autoimmune liver disease of humans. Patient sera are characterized by a high frequency of autoantibodies to a M r 70,000 mitochondrial antigen a component of the M2 antigen complex. The authors have identified a human cDNA clone encoding the complete amino acid sequence of this autoantigen. The predicted structure has significant similarity with the dihydrolipoamide acetyltransferase of the Escherichia coli pyruvate dehydrogenase multienzyme complex. The human sequence preserves the Glu-Thr-Asp-Lys-Ala motif of the lipoyl-binding site and has two potential binding sites. Expressed fragments of the cDNA react strongly with sera from patients with primary biliary cirrhosis but not with sera from patients with autoimmune chronic active hepatitis or sera from healthy subjects

  7. Primary Biliary Cirrhosis Is a Generalized Autoimmune Epithelitis

    Directory of Open Access Journals (Sweden)

    Jun Gao

    2015-03-01

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

    The etiopathogenesis of bile duct lesion in primary biliary cirrhosis is unknown, though the participation of bacteria and/or their components and products is suspected. In this study, we tried to detect and identify bacteria in the bile of patients with primary biliary cirrhosis by polymerase chain reaction using universal bacterial primers of the 16S ribosomal RNA gene. Gallbladder bile samples from 15 patients with primary biliary cirrhosis, 5 with primary sclerosing cholangitis, 5 with hepatitis C virus-related liver cirrhosis, 11 with cholecystolithiasis, and from 12 normal adult gallbladders were used. In addition to the culture study, partial bacterial 16S ribosomal RNA gene was amplified by polymerase chain reaction (PCR) taking advantage of universal primers that can amplify the gene of almost all bacterial species, and the amplicons were cloned and sequenced. Sequence homology with specific bacterial species was analyzed by database research. Bacterial contamination at every step of the bile sampling, DNA extraction and PCR study was avoided. Furthermore, to confirm whether bacterial DNA is detectable in liver explants, the same analysis was performed using 10 liver explants of patients with primary biliary cirrhosis. In primary biliary cirrhosis, 75% (p<0.0001) of 100 clones were identified as so-called gram-positive cocci while these cocci were positive in only 5% in cholecystolithiasis (p<0.0001). In cholecystolithiasis gram-negative rods were predominant instead. One bacterial species detected in a normal adult was not related to those detected in primary biliary cirrhosis and cholecystolithiasis patients. No bacterial DNA was detected by PCR amplification in 10 liver explants of patients with primary biliary cirrhosis. The present results raise several possible roles of gram-positive bacteria in bile in the etiopathogenesis of primary biliary cirrhosis. However, these results could also reflect an epiphenomenon due to decreased bile flow in the

    Patients with advanced gallbladder and biliary tract carcinoma face a dismal prognosis, as no effective palliative chemotherapy exists. The antitumor effect of gemcitabine is schedule-dependent rather than dose-dependent. We evaluated the activity of a prolonged infusion of gemcitabine in advanced gallbladder and biliary tract carcinomas. Nineteen consecutive eligible patients were enrolled. All patients were required to have histologically confirmed diagnosis and measurable disease. Gemcitabine was infused over 24 hours at a dose of 100 mg/m 2 on days 1, 8, and 15. Treatment was repeated every 28 days until progression of disease or limiting toxicity. Tumor response was evaluated every second course by computed tomography (CT) scans. Eighteen patients were evaluable for response. A total of 89 cycles of therapy were administered. One partial response was observed (6%; 95% confidence interval (CI): 0–27%) and ten additional patients had stable disease for at least two months (disease control rate 61%; 95% CI: 36–83%). The therapy was well tolerated, with moderate myelosuppression as the main toxicity. The median time to tumor progression and median overall survival was 3.6 months (95% CI 2.6–4.6 months) and 7.5 months (95% CI 6.5–8.5 months), respectively. Weekly 24-hour gemcitabine at a dose of 100 mg/m 2 is well tolerated. There was a relatively high rate of disease control for a median duration of 5.3 months (range 2.8–18.8 months). However, the objective response rate of this regimen in gallbladder and biliary tract carcinomas was limited

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

    To compare transarterial chemoembolization (TACE)-related hepatic toxicities of conventional TACE (cTACE) and drug-eluting beads TACE (DEB-TACE) in patients with intermediate-stage hepatocellular carcinoma. In this retrospective study, 151 consecutive patients undergoing cTACE or DEB-TACE and MRI 3-6 weeks before and after therapy were included. Toxicity was assessed on imaging (global hepatic damages (GHD), overall biliary injuries, biliary cast, bile duct dilatation, intrahepatic biloma, portal thrombosis), and clinico-biological follow-ups. Tumour response, time to progression (TTP), and overall survival were assessed. Factors influencing complication rate were identified by generalized equation logistic regression model. Biliary injuries and intrahepatic biloma incidence were significantly higher following DEB-TACE (p < 0.001). DEB-TACE showed a significant increased risk of GHD (OR: 3.13 [1.74-5.63], p < 0.001) and biliary injuries (OR: 4.53 [2.37-8.67], p < 0.001). A significant relationship was found between baseline prothrombin value and GHD, biliary injuries and intrahepatic biloma (all p < 0.01), and between the dose of chemotherapy and intrahepatic biloma (p = 0.001). Only TTP was significantly shorter following DEB-TACE compared to cTACE (p = 0.025). DEB-TACE was associated with increased hepatic toxicities compared to cTACE. GHD, biliary injuries, and intrahepatic biloma were more frequently observed with high baseline prothrombin value, suggesting that cTACE might be more appropriate than DEB-TACE in patients with less advanced cirrhosis.

    Full Text Available Transverse myelitis is an acute inflammatory process, affecting one or more segments of the spinal cord. Its association with primary biliary cirrhosis has been documented in only four cases - all along with Sjögren's syndrome. Herein, we report for the first time, a patient who developed recurrent acute transverse myelitis in association with primary biliary cirrhosis without any clinical or histological indication of Sjögren's syndrome. A 42-year-old woman with primary biliary cirrhosis developed acute onset quadriparesis and urinary retention. Diagnostic evaluation excluded the presence of Sjögren's syndrome, other autoimmune syndromes, infections and multiple sclerosis. Magnetic resonance imaging of the spinal cord disclosed signal intensity abnormalities from C1 to T2 after gadolinium enhancement. As diagnosis of acute transverse myelitis was prominent, the patient was treated with intravenous methylprednisolone. The patient had a fair outcome despite an early recurrence of the symptoms after treatment withdrawal.

    Full Text Available Nadya Al-Harthy,1 Teru Kumagi21Gastroenterology and Hepatology, Royal Hospital, Muscat, Oman; 2Gastroenterology and Metabology, Ehime University Graduate School of Medicine, Ehime, JapanAbstract: Primary biliary cirrhosis (PBC is a chronic inflammatory autoimmune disease that mainly targets the cholangiocytes of the interlobular bile ducts in the liver. It is a rare disease with prevalence of less than one in 2000. Its prevalence in developing countries is increasing presumably because of growth in recognition and knowledge of the disease. PBC is thought to result from a combination of multiple genetic factors and superimposed environmental triggers. The contribution of the genetic predisposition is evidenced by familial clustering. Several risk factors, including exposure to infectious agents and chemical xenobiotics, have been suggested. Common symptoms of the disease are fatigue and pruritus, but most patients are asymptomatic at first presentation. The prognosis of PBC has improved because of early diagnosis and use of ursodeoxycholic acid, the only established medical treatment for this disorder. When administered at adequate doses of 13–15 mg/kg/day, up to two out of three patients with PBC may have a normal life expectancy without additional therapeutic measures. However, some patients do not respond adequately to ursodeoxycholic acid and might need alternative therapeutic approaches.Keywords: primary biliary cirrhosis, natural history, long-term outcome, ursodeoxycholic acid, biochemical response, target therapy

    Sixty-five patients with squamous carcinoma of the esophagus (32 patients), carcinoma of the stomach (18 patients) and carcinoma of the biliary tract (15 patients) received from 6000 to 7000 equivalent rad (60-70 Gray equivalents) of helium radiotherapy at 2.0 GyE per fraction, four fractions per day, using multiportal, spread-out Bragg peak therapy. All patients had locally advanced disease without evidence of distant metastases. Partial compensation for tissue inhomogeneities was accomplished. Although palliation of symptoms and regression of tumor was commonly seen, local failure occurred in most patients (77%). The median survival was 8 months. It does not appear that an increase in tumor dose relative to normal tissues can be achieved that would be high enough to increase locoregional control rates over historical control rates with low-LET irradiation. Further studies will be carried out with heavier particles such as neon or silicon in hopes of achieving greater biological effect on these difficult-to-control tumors. 22 references, 6 figures, 1 table

    2017-01-01

    Primary biliary cholangitis (PBC) is a rare autoimmune liver disease characterized by chronic cholestasis. Treatment with the accepted primary therapy ursodeoxycholic acid (UDCA) has been shown to be associated with delayed disease progression probably through reduced impact of cholestatic injury on the target biliary epithelial cells. Patients with inadequate response to UDCA (which can be identified through validated biochemical criteria) are at increased risk of disease progression, need for liver transplantation, and death. Obeticholic acid (OCA) is a farnesoid X receptor (FXR) agonist which has been evaluated as a second-line therapy in PBC and has been recently licensed by the Food and Drug Administration and European Medicines Agency for use in patients showing an inadequate response to UDCA or who are unable to tolerate it. Although evidence for biochemical improvement by OCA is compelling, there is, as yet, no evidence that OCA improves hard clinical outcomes or quality of life. In addition, OCA may not be suitable for PBC patients with pruritus as it can worsen the symptom. Other novel agents currently in clinical development may have better side-effect profile. Fibrates have the potential but currently lack high quality evidence to support their routine clinical use in PBC. Symptom management of PBC is challenging and ASBT inhibitors and rituximab are being evaluated for pruritus and fatigue, respectively. © 2017 S. Karger AG, Basel.

    To evaluate the effectiveness of percutaneous biliary stone removal as a primary treatment in cases with difficulties to use an endoscopy. From March 2004 to May 2011, 17 patients who underwent primary percutaneous biliary stone removal (Group 1) and 34 case-matched patients who underwent primary endoscopic biliary stone removal were selected (Group 2). The inclusion criteria were as follows: patients who had 1) ≥ 15 mm bile duct stones, 2) intrahepatic bile duct stones, 3) bile duct stones with a history of previous gastrointestinal bypass surgery. In the present study were analyzed the success rates, the length of postprocedural hospital stay, the change of Amylase/Lipase values and complications post procedure. Statistical analysis was performed using paired t-test and unpaired t-test. The success rate was higher in Group 1 (94.1%) than in Group 2 (85.3%). Length of post procedural hospital stay and the post procedural amylase level were significantly increased in Group 2 (p = 0.036 and p = 0.017, respectively). In cases of bile duct stones with difficulties in the use of an endoscopy a percutaneous biliary stone removal can be efficient as a primary treatment.

    Background and study aims: Biliary stricture after radiofrequency ablation (RFA) for nodules of hepatocellular carcinoma (HCC) close to major bile ducts sometimes causes septic complications and liver failure. Therefore, it may require interventional drainage for decompression during the follow-up period. The purpose of this study is to clarify the feasibility and safety of bile duct cooling using an endoscopic nasobiliary drainage (ENBD) tube in RFA for HCC close to major bile ducts. Patients and methods: Between August 2003 and July 2007, 14 consecutive patients (14 nodules) undergoing RFA with cooling by an ENBD tube for HCCs close to major bile ducts were enrolled in this study. We infused chilled saline solution via the ENBD tube at 1 ml/s to prevent heat damage during RFA. As controls, 11 patients (13 nodules) undergoing RFA without cooling close to major bile ducts between April 2001 and August 2003 were reviewed. The major outcomes for evaluation were biliary complications and the secondary outcome was local tumor recurrence. Results: There were no significant differences in tumor recurrence between the two groups. However, the rate of biliary complications was significantly lower in the cooling group than in the non-cooling group (0% vs. 39%, P = 0.02). Conclusions: Cooling of bile ducts via an ENBD tube can prevent biliary complications induced by RFA of HCC close to major bile ducts without increasing local recurrence. This technique increases indication of RFA in difficult cases.

    Objective: To evaluate the methodology and effectiveness of interventional biliary drainage for patients with multiple biliary tract obstruction (MBO). Methods: Twenty-one patients with MBO caused by cholangiocarcinoma in 13 cases, primary hepatocellular carcinoma in 5 cases and porta hepatic metastases in 3 cases were included. According to types of biliary tract occlusion, the authors performed different combined interventional draining procedures. That is, thirteen cases were performed with right and left bile duct stent implantation respectively; three cases with stent insertion between left and right bile ducts and catheter for external draining in right bile duct; three cases with right bile duct stent placement and catheter for external draining in left bile duct; two cases with anterior right bile tract stent placement and posterior right bile tract for external draining while left bile duct for internal (one case) or external (one case) draining. Results: All together 36 stents were implanted in 21 patients. 35 stents have obtained satisfactory internal draining function and one stent has not shown function due to malposition. Jaundice disappeared completed in 19 of 21 cases, and disappeared incompletely in 2 cases. Conclusions: Multiform biliary internal and/or external drainage is effective for most patients with MBO

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

Grave's disease can cause asymptomatic elevation of liver enzymes, jaundice and rarely acute liver failure. It is associated with other autoimmune diseases like autoimmune hepatitis, or primary biliary cirrhosis. The cause of jaundice in Grave's disease is multifactorial.

    AIM: To evaluate the myoelectric manifestations of peripheral fatigability in patients with primary biliary cirrhosis in comparison to healthy subjects. METHODS: Sixteen women with primary biliary cirrhosis without comorbidity and 13 healthy women matched for age and body mass index (BMI) completed the self-reported questionnaire fatigue impact scale. All subjects underwent surface electromyography assessment of peripheral fatigability. Anterior tibial muscle isometric voluntary contraction was executed for 20 s at 80% of maximal voluntary isometric contraction. During the exercise electromyographic signal series were recorded and root mean square (expression of central drive) as well as mean and median of electromyographic signal frequency spectrum (estimates of muscle fatigability) were computed. Each subject executed the trial two times. EMG parameters were normalized, then linear regression was applied and slopes were calculated. RESULTS: Seven patients were fatigued (median fatigue impact scale score: 38, range: 26-66) and 9 were not fatigued (median fatigue impact scale score: 7, range: 0-17). The maximal voluntary isometric contraction was similar in patients (82, 54-115 N) and controls (87, 74-101 N), and in patients with high (81, 54-115 N) and low fatigue impact scale scores (86, 65-106 N). Root mean square as well as mean and median of frequency spectrum slopes were compared with the Mann-Whitney U test, and no significant difference was found between fatigued and non-fatigued patients and controls. CONCLUSION: No instrumental evidence of peripheral fatigability can be found in women with primary biliary cirrhosis but no comorbidity, suggesting that fatigue in such patients may be of central origin.

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

    Full Text Available A 52-year-old man visited our hospital complaining of anorexia and fatigue two months after receiving orthotopic liver transplantation for hepatocellular carcinoma. A laboratory investigation demonstrated a clinical picture of obstructive jaundice. T-tube cholangiography showed biliary stricture over the anastomotic site. Percutaneous transluminal balloon dilatation and stenting was attempted but failed. Magnetic resonance cholangiography showed possible tumor recurrence over the site of the anastomotic biliary stricture. A biopsy sample was obtained via ultrasound-guided aspiration and histopathological study revealed inflammatory and fibrotic changes. With high suspicion of recurrence of the hepatocellular carcinoma, surgical exploration was performed and an intraoperative frozen section proved the recurrence. We thus diagnosed this case as a recurrence of hepatocellular carcinoma after liver transplantation. To our knowledge, there have been no previous reports of early tumor recurrence after liver transplantation being the cause of an anastomotic biliary stricture.Un varón de 52 años visitó nuestro hospital quejándose de anorexia y fatiga a los dos meses de haber recibido un trasplante hepático ortotópico a causa de un carcinoma hepatocelular.

    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.

    1983-01-01

    Instead of the widely recommended approach of treating hilar carcinoma of the bile ducts by simple palliative biliary drainage, step by step a policy of primarily aiming at resection for cure has been adopted. So far in 11 out of 22 patients excision of the tumor was possible by resection of the hepatic duct confluence; in 4 cases a left hemihepatectomy had to be added because of carcinomatous infiltration of the left liver lobe or the left hepatic artery. The multiple bile duct openings remaining after resection of such tumors were reconstructed to one or two orifices and a bi- or unilateral Roux-en-Y cholangiojejunal anastomosis performed. In further 3 cases orthotopic liver transplantation was necessary to remove all visibly infiltrated tissue. In the remaining 8 patients because of documented extrahepatic carcinomatous spread palliative biliary drainage by a percutaneous U-tube or an endoprothesis was indeed considered the only reasonable measure. Despite the relatively high resectional rate of 60% and the extensive operations performed early mortality was confined to one patient who succumbed to septic endocarditis 6 weeks after the operation. At present the longest postoperative interval without recurrence amounts to 3 1/2 years. Nine patients free of recurrent disease are in perfect health; in 3 patients in whom a recurrence was observed after 1/2, 1 1/2 and 2 years meanwhile palliation was perfect. In contrast all patients with unresected tumors but carrying draining stents suffered from cholangitis and after 1 1/2 years all but one had died. In conclusion resectional therapy for hilar carcinoma seems possible with acceptable risk. Since only resection can provide potential cure and also palliation was better than that achieved by draining tubes a more aggressive attitude to the treatment of these lesions is advocated from our experience.

    Full Text Available Simultaneous double cancers in the biliary system are rare. Most are associated with pancreaticobiliary maljunction (PBM. However, it can occur in patients without PBM. Differentiation between these events is important since these two mechanistic origins imply different stages of disease, as well as different subsequent treatments and prognoses. Herein, we report a case of ampullary carcinoma associated with gall bladder carcinoma diagnosed nonoperatively and palliated with biliary metal stenting.

    Primary biliary cholangitis is a chronic, cholestatic liver disease characterized by a heterogeneous presentation, symptomatology, disease progression and response to therapy. In contrast, clinical management and treatment of PBC is homogeneous with a 'one size fits all' approach. The evolving research landscape, with the emergence of the -omics field and the availability of large patient cohorts are creating a unique opportunity of translational epidemiology. Furthermore, several novel disease and symptom-modifying agents for PBC are currently in development. The time is therefore ripe for precision medicine in PBC. In this manuscript we describe the concept of precision medicine; review current approaches to risk-stratification in PBC, and speculate how precision medicine in PBC might develop in the near future.

    Cholangiograms and clinical histories of 82 patients with biopsy-proved bile duct carcinoma were reviewed. The carcinomas were classified according to morphologic findings and clinical outcome. Ulcerative colitis and antecedent inflammatory disease of the biliary tree, particularly primary sclerosing cholangitis, seem to predispose to the development of bile duct carcinoma. Focal stenotic lesions were the most common morphologic type (62/82). Polypoid carcinomas and diffuse sclerosing carcinomas were less common and of about equal frequency. Prognosis was best for patients with polypoid carcinomas and worst for those with diffuse sclerosing carcinomas. In 69 cases (84%), the tumors involved the intrahepatic or proximal extrahepatic ducts, makin curative resection difficult or impossible. Patients with carcinomas limited to the more distal extrahepatic bile ducts had a longer average survival and a higher probability of surgical cure. Proper management of patients with bile duct carcinoma requires a complete and accurate cholangiographic evaluation of the morphology, location, and extent of the disease

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

  16. A phenomenological study of fatigue in patients with primary biliary cirrhosis.

    This paper reports the findings of research on the lived experience of fatigue in patients with primary biliary cirrhosis - a type of chronic liver disease. Fatigue is a universal phenomenon, commonly associated with both acute and chronic illness, but also seen in healthy individuals. However, it is not often addressed in healthcare encounters despite its disabling nature, perhaps because of the multitude of contributing factors and the lack of effective treatments. It is a common and debilitating symptom in patients with primary biliary cirrhosis. Despite the prevalence of fatigue in this condition, patients' experiences of this symptom have not been researched. An interpretive-phenomenological approach developed by van Manen was chosen and this combines features of descriptive and interpretive phenomenology. Eight participants were interviewed during 2005 about their fatigue experience. Thematic analysis was conducted. Five themes were identified: an unreliable body, fatigue as always present yet insidious, planning a life to conserve energy, struggling to maintain normality and emotional consequences. These themes reflected the unrelenting, intrusive nature of fatigue into the lives of those affected. This research will provide empathic insight into the fatigue experience in this condition and generate communication about coping strategies. It will add to the body of research on fatigue in chronic conditions and may generate ideas for intervention research.

    Purpose : To evaluate the effectiveness and tolerance of patients of external beam radiotherapy of carcinoma of the extrahepatic biliary system (EHBS) including gall bladder (GB) and extrahepatic bile ducts (EHBD) and to define the role of radiotherapy for these tumors. Methods and Materials : We retrospectively analyzed the records of 43 patients with carcinoma of the EHBS treated with external beam radiotherapy at our institution between April, 1986 and July, 1994. Twenty three patients had GB cancers and remaining 20 patients did EHBD cancers. Of those 23 GB cancers, 2 had Stage II, 12 did Stage III and 9 did Stage IV disease, respectively. Male to female ratio was 11 to 12. Fifteen patients underwent radical surgery with curative intent and 8 patients did biopsy and bypass surgery alone. Postoperatively 16 patients were irradiated with 4500 cGy or higher doses and 4 patients with 3180 to 4140 cGy. Follow up periods ranged from 8 to 34 months. Results : overall median survival time of patients with GB cancer was 11 months. Median survival time for patients with Stage III and IV disease were 14 months and 5 months, respectively. Corresponding two year survival rates were 36%(4/11) and 13%(1/8), respectively. Those who underwent surgery with curative intent showed significantly better survival at 12 months than those who underwent bypass surgery alone(67% vs 13%). None of the patients died of treatment related complications. Median survival time for entire group of 20 EHBD patients was 10 months. Median survivals of 10 Stage III and 7 Stage IV disease were 10 and 8 months, respectively. Two patients who underwent Whipple's procedure had 11 and 14 month survival and those treated with resection and drainage showed median survival of 10 month. Conclusion : Postoperative external beam radiotherapy for carcinoma of the extrahepatic billary system is well tolerated and might improve survival of patients. especially those with respectable lesions with microscopic or

    A reliable liver autoimmune serology for the diagnosis of primary biliary cholangitis (PBC) is of particular importance. Recognition of patients at early stages and prompt treatment initiation may alter the outcome, slow progression, delays liver failure, and improves survival. In this review, we summarize and discuss the published data obtained from literature searches from PubMed and The National Library of Medicine (USA) and our own experience on the current and potential molecular based approaches to the diagnosis of PBC. Expert commentary: Standardization of liver diagnostic serology and clinical governance are two major points as antimitochondrial antibodies are the diagnostic hallmark of the disease and PBC-specific antinuclear antibodies could assist in the diagnosis and estimation of prognosis. New biomarkers such as novel autoantibodies, genetic polymorphisms, metabolomic profiling, micro-RNA and epigenetics may assist to the understanding, diagnosis and management of the disease.

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

    Fascioliasis is a zoonotic infestation caused by Fasciola hepatica that usually attacks mammals, such as goats, sheep and cattle. The parasites can infect humans via freshwater plants contaminated with encysted metacercariae. In the acute phase, which involves hepatic invasion, the disease may present with abdominal pain, mild fever and hepatomegaly. In the chronic phase, the parasites settle into the biliary tracts, and then cause cholangitis and cholestasis. Sometimes, the disease may mimic malignancies, creating a mass appearance. Endoscopic retrograde cholangiopancreatography (ERCP) is an important diagnostic and treatment method because it allows simultaneous diagnosis and treatment. Here, we present a 44-year-old female patient who presented to our hospital with complaints of abdominal pain, nausea, vomiting, anorexia and weight loss. After diagnostic investigations with laboratory and imaging methods, she was initially hospitalized with a preliminary diagnosis of cholangiocellular carcinoma (CCC). However, after a full work-up, the patient was diagnosed with Fasciola hepatica via ERCP and parasites were extracted with ERCP at the same time and then treated with a single dose of triclabendazole 10 mg/kg. Two months later, the clinical status of the patient had improved markedly, with resolution of all symptoms and all laboratory and imaging tests returning to within normal limits.

    Full Text Available Primary orbital squamous cell carcinoma is a rare entity. There is little published literature. We report a case of primary squamous cell carcinoma of the orbital soft tissues. Surgical resection offered the best treatment for the patient. Complete resection of the lesion was achieved. The patient received adjuvant radiotherapy due to the proximity of the lesion to the surgical margins. Surgical treatment is feasible and should be considered as part of the surgeon's arsenal. However, therapeutic decisions must be made on a case-by-case basis

    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.

    Multidisciplinary treatment is a useful approach to unresectable non-metastatic bile duct carcinoma with invasion of the hepatic artery and portal vein. The authors developed a multidisciplinary treatment consisting of chemoradiation therapy combined with intraluminal bile duct irradiation plus external irradiation and systemic or local chemotherapy. The aim of this regimen was to improve the ability to locally control bile duct carcinoma by intraluminal irradiation and to shorten the treatment period compared to external irradiation therapy alone. According to the treatment schedule whole-body irradiation is performed first and followed by systemic administration of 5-fluorouracil (5-FU, 600 mg/m 2 /day) and cisplatin (CDDP, 10 mg/m 2 /day) after biliary stenting plus simultaneously intraluminal irradiation (8 Gy/week x 3, total 24 Gy) administered with 192 Ir-RALS (Remote After Loading System). Two novel types of applicators specifically designed by the authors for intraluminal radiation of the bile duct were improved. The authors have used this multidisciplinary approach to treat 3 patients with bile duct carcinoma. Its application has shortened the course of multidisciplinary therapy to about 6 weeks, and the patients have surviveed more than 6-8 months without recurrence. (K.H.)

    Osteomalacia, a metabolic bone disease characterized by the inability to mineralize new osteoid, can be caused by vitamin D deficiency. We report a patient with symptomatic, biochemical, and imaging evidence of osteomalacia due to vitamin D deficiency, who as a result of work up for bone disease was diagnosed with early primary biliary cirrhosis. Osteomalacia was treated with high-dose vitamin D and serial bone density scans showed evidence of increasing bone mineral density suggesting osteoid mineralization in response to treatment. The diagnosis of cholestatic liver disease should be considered in all patients presenting with osteomalacia due to vitamin D deficiency, particularly if other cholestatic liver enzymes are elevated in addition to alkaline phosphatase.

    In recent years, primary biliary cirrhosis is mostly diagnosed in patients who are asymptomatic; however, a proportion of cases still present with typical complaints such as fatigue and/or pruritus. We compared biochemical, histological and immunological features of patients with or without fatigue and/or pruritus at onset to see whether the different clinical presentation may eventually impact on disease progression. We analysed the Bologna cohort of 216 patients with primary biliary cirrhosis referred to our Centre between 1997 and 2007, according to symptomatic (fatigue and/or pruritus) or asymptomatic presentation. Clinical, biochemical, histological and immunological feature at diagnosis, response to ursodeoxycholic acid and progression of the disorder were compared after a mean follow-up of 81 ± 75 months. At diagnosis, symptomatic patients were significantly more often women (98.6% vs. 87.2%, P = 0.004), younger (mean age 49 ± 12 vs. 55 ± 12 years, P = 0.003) and with more pronounced biochemical activity, as indicated by higher alkaline phosphatase (mean 2.93 ± 2 vs. 2.12, P = 0.002) and aminotransferase (mean 1.92 ± 1 vs. 1.47 ± 1.27, P = 0.014) levels, whereas histological stage and autoantibody profile were similar. Symptomatic patients were less likely to respond to ursodeoxycholic acid therapy (63% vs. 81%, P = 0.006) and developed more often cirrhosis and its complications (31% vs. 13%, P = 0.004). Fatigue and/or pruritus at onset identify a subset of patients with primary biliary cirrhosis who preferentially are women, younger, with a particularly active disease, less responsive to ursodeoxycholic acid treatment, and more inclined to evolve to cirrhosis and its complications. © 2014 John Wiley & Sons A/S.

    Parasitic infections of the biliary tract are a common cause of biliary obstruction in endemic areas. This article focuses on primary biliary parasites: Ascaris lumbricoides, Clonorchis sinensis, Opisthorchis viverrini, Opisthorchis felineus, Dicrocoelium dendriticum, Fasciola hepatica, and Fasciola gigantica. Tropical and subtropical countries have the highest incidence and prevalence of these infections. Diagnosis is made primarily through direct microscopic examination of eggs in the stool, duodenal, or bile contents. Radiologic imaging may show intrahepatic ductal dilatation, whereas endoscopic retrograde cholangiopancreatography can be used diagnostically and therapeutically. However, oral treatment is inexpensive and effective for most of these parasites and can prevent untoward consequences. Primary and alternative treatments are available and are reviewed in this article.

    Ursodeoxycholic acid (UDCA) exerts anticholestatic, antifibrotic and antiproliferative effects in primary biliary cirrhosis (PBC) via mechanisms not yet fully understood. Its adequate biliary enrichment is considered mandatory for therapeutic efficacy. However, precise determination of biliary enrichment of UDCA is not possible in clinical practice. Therefore, we investigated (i) the relationship between biliary enrichment and plasma pharmacokinetics of UDCA, (ii) the effect of UDCA on plasma and biliary bile acid composition and conjugation patterns, and (iii) on the intestinal detoxification machinery in patients with PBC and healthy controls. In 11 PBC patients and 11 matched healthy subjects, cystic bile and duodenal tissue were collected before and after 3 weeks of administration of UDCA (15 mg/kg/day). Extensive pharmacokinetic profiling of bile acids was performed. The effect of UDCA on the intestinal detoxification machinery was studied by quantitative PCR and Western blotting. The relative fraction of UDCA and its conjugates in plasma at trough level[x] correlated with their biliary enrichment[y] (r=0.73, p=0.0001, y=3.65+0.49x). Taurine conjugates of the major hydrophobic bile acid, chenodeoxycholic acid, were more prominent in bile of PBC patients than in that of healthy controls. Biliary bile acid conjugation patterns normalized after treatment with UDCA. UDCA induced duodenal expression of key export pumps, BCRP and P-glycoprotein. Biliary and trough plasma enrichment of UDCA are closely correlated in PBC and health. Taurine conjugation may represent an adaptive mechanism in PBC against chenodeoxycholic acid-mediated bile duct damage. UDCA may stabilize small intestinal detoxification by upregulation of efflux pumps. Copyright © 2012. Published by Elsevier B.V.

    Peritoneum is a site for both primary and secondary tumors. Primary peritoneal tumors are fairly rare. The most common primary tumors of the peritoneum are malignant mesothelioma and serous papillary adenocarcinoma. Clear cell carcinoma of the peritoneum is extremely rare and often misdiagnosed as mesothelioma, serous carcinoma, or metastatic adenocarcinoma, so it represents a diagnostic challenge for both clinicians and pathologists. Up to date, to the best of our knowledge, only 11 cases of primary peritoneal clear cell carcinoma have been reported in the English literature. Distinguishing this tumor of the peritoneum versus ovarian carcinoma can be problematic. Herein, we report a rare case of primary peritoneal clear cell carcinoma occurring in a 49-year-old woman, along with a review of the literature. © The Author(s) 2015.

    Endoscopic ultrasound-guided rendezvous technique (EUS-RV) has emerged as an effective salvage method for unsuccessful biliary cannulation. However, its application for benign and resectable malignant biliary disorders has not been fully evaluated. To assess the efficacy and safety of EUS-RV for benign and resectable malignant biliary disorders. This was a multicenter prospective study from 12 Japanese referral centers. Patients who underwent EUS-RV after failed biliary cannulation for biliary disorder were candidates for this study. Inclusion criteria were unsuccessful biliary cannulation for therapeutic endoscopic retrograde cholangiopancreatography with benign and potentially resectable malignant biliary obstruction. Exclusion criteria included unresectable malignant biliary obstruction, inaccessible papillae due to surgically altered upper gastrointestinal anatomy or duodenal stricture, and previous sphincterotomy and/or biliary stent placement. The primary outcome was the technical success rate of biliary cannulation; procedure time, adverse events, and clinical outcomes were secondary outcomes. Twenty patients were prospectively enrolled. The overall technical success rate and median procedure time were 85% and 33 min, respectively. Guidewire manipulation using a 4-Fr tapered tip catheter contributed to the success in advancing the guidewire into the duodenum. Adverse events were identified in 15% patients, including 2 with biliary peritonitis and 1 mild pancreatitis. EUS-RV did not affect surgical maneuvers or complications associated with surgery, or postoperative course. EUS-RV may be a safe and feasible salvage method for unsuccessful biliary cannulation for benign or resectable malignant biliary disorders. Use of a 4-Fr tapered tip catheter may improve the overall EUS-RV success rate.

    Full Text Available Primary Fallopian Tube Carcinoma (PFTC is rare and accounts for about 0.3% of all gynecologic cancers. Less than 1500 cases have been reported in the literature. It arises in postmenopausal women and typically presents with abdominal pelvic pain, vaginal bleeding and watery discharge. However, a correct diagnosis is rarely achieved preoperative, and in many cases, the diagnosis is made after incidental surgery for unrelated conditions commonly being ovarian carcinoma . Compared with ovarian carcinoma, PFTC more often presents at early stages, but it has a worse prognosis. PFTC is usually managed in the same manner as ovarian cancer. We report a case of Left PFTC that presented as Left ovarian mass, and we briefly review the literature.

    We genotyped individuals with primary biliary cirrhosis and unaffected controls for suggestive risk loci (genome-wide association P < 1 × 10−4) identified in a previous genome-wide association study. Combined analysis of the genome-wide association and replication datasets identified IRF5-TNPO3 (combined P = 8.66 × 10−13), 7q12-21 (combined P = 3.50 × 10−13) and MMEL1 (combined P = 3.15 × 10−8) as new primary biliary cirrhosis susceptibility loci. Fine-mapping studies showed that a single variant accounts for the IRF5-TNPO3 association. As these loci are implicated in other autoimmune conditions, these findings confirm genetic overlap among such diseases. PMID:20639879

  18. Biliary Innate Immunity: Function and Modulation

    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.

    Several hepatobiliary disorders have been reported in ulcerative colitis (UC) patients with primary sclerosing cholangitis (PSC) being the most specific. Primary biliary cholangitis (PBC), previously known as primary biliary cirrhosis, rarely occurs in UC. We present two PBC cases of 67 and 71 years who suffered from long-standing UC. Both patients were asymptomatic but they had increased cholestatic enzymes and high titres of antimitochondrial antibodies (AMA)-the laboratory hallmark of PBC. After careful exclusion of other causes of cholestasis by MRI/magnetic resonance cholangiopancreatography (MRCP), virological and microbiological investigations, a diagnosis of PBC associated with UC was established. The patients started ursodeoxycholic acid (13 mg/kg/day) with complete response. During follow-up, both patients remained asymptomatic with normal blood biochemistry. Although PSC is the most common hepatobiliary manifestation among patients with UC, physicians must keep also PBC in mind in those with unexplained cholestasis and repeatedly normal MRCP. In these cases, a reliable AMA testing can help for an accurate diagnosis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    2011-01-01

    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

    Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease characterized by inflammatory destruction of median size intrahepatic bile ducts. The characteristic histological process is described as chronic nonsuppurative destractive cholangitis (CNSDC). Our knowledge for the pathogenesis of PBC remains incomplete. However, immunological mechanisms seems to play one of the most important role. The immunohistochemical examination represents accumulation of stimmulated T lymphocytes in the portal area. Attachment of CD8 positive T cells to bile duct epithelial cells is observed. The animal model of PBC indicates autoreactive CD4 positive T cells seems to be important at the early stage of PBC and CD8 positive cytotoxic T cells are essential for the progression of the disease. PBC is histologically classified into four overlapping stages by Scheuer. Clinically, PBC is classified into asymptomatic PBC (aPBC), PBC with itching alone (s1PBC) and with jaundice (s2PBC).

    Objective: To investigate the expression and clinical significance of KIAA1199 in primary hepatocellular carcinoma. Methods: A total of 136 cases of primary hepatocellular carcinoma tissues and paired adjacent tissues were collected. Immunohistochemistry and Western blot were used to detect the expression of KIAA1199 in primary hepatocellular carcinoma tissues and paired adjacent tissues. The relationship between KIAA1199 and clinicopathological parameter of primary hepatocellular carcinoma was analyzed. Results: The positive rate of KIAA1199 in primary hepatocellular carcinoma was 82.3% (112/136), which was higher than that in paired para-cancerous tissues (14.7%, 20/136). High expression of KIAA1199 was significantly correlated with age, cirrhosis history, tumor size, tumor number, degree of differentiation, TNM staging and microvenous invasion (MVI) ( P 0.05). The Kaplan-Meier survival curves indicated that high KIAA1199 expression was associated with poor survival ( P hepatocellular carcinoma, which is significantly correlated with the clinicopathological features and prognosis, high expression of KIAA1199 increased the risk of death in patients with primary hepatocellular carcinoma.

    Since the introduction of MR cholangiography (MRC) diagnostic imaging of the biliary tract has been significantly improved. While percutaneous ultrasonography is still the primary examination, computed tomography (CT), conventional magnetic resonance imaging (MRI), as well as the direct imaging modalities of the biliary tract - iv cholangiography, endoscopic-retrograde-cholangiography (ERC), and percutaneous-transhepatic-cholangiography (PTC) are in use. This article discusses the clinical value of the different diagnostic techniques for the various biliary pathologies with special attention to recent developments in MRC techniques. An algorithm is presented offering a rational approach to biliary disorders. With further technical improvement shifts from ERC(P) to MRC(P) for biliary imaging could be envisioned, ERCP further concentrating on its role as a minimal invasive treatment option. (orig.) [de

    Full Text Available Christopher L Bowlus Division of Gastroenterology and Hepatology, University of California Davis, Davis, CA, USA Abstract: Primary biliary cholangitis (PBC, previously known as primary biliary “cirrhosis”, is a rare autoimmune liver disease characterized by the hallmark autoantibodies to mitochondrial antigens and immune-mediated destruction of small bile duct epithelial cells leading to cholestasis and cirrhosis. Surprisingly, while immune modulators have not been effective in the treatment of PBC, supplementation with the hydrophilic bile acid (BA ursodeoxycholic acid (UDCA has been demonstrated to slow the disease progression. However, a significant minority of PBC patients do not have a complete response to UDCA and remain at risk of continued disease progression. Although the mechanisms of action are not well understood, UDCA provided proof of concept for BA therapy in PBC. Obeticholic acid (OCA, a novel derivative of the human BA chenodeoxycholic acid, is a potent agonist of the nuclear hormone receptor farnesoid X receptor, which regulates BA synthesis and transport. A series of clinical trials of OCA in PBC, primarily in combination with UDCA, have established that OCA leads to significant reductions in serum alkaline phosphatase that are predicted to lead to improved clinical outcomes, while dose-dependent pruritus has been the most common adverse effect. On the basis of these studies, OCA was given conditional approval by the US Food and Drug Administration with plans to establish the long-term clinical efficacy of OCA in patients with advanced PBC.

    2014-04-01

    This review is to summarize the current knowledge about preoperative biliary drainage (PBD) in patients with biliary obstruction caused by pancreatic cancer. Most patients with pancreatic carcinoma (85%) will present with obstructive jaundice. The presence of toxic substances as bilirubin and bile salts, impaired liver function and altered nutritional status due to obstructive jaundice have been characterized as factors for development of complications after surgery. Whereas PBD was to yield beneficial effects in the experimental setting, conflicting results have been observed in clinical studies. The meta-analysis from relative older studies as well as more importantly a recent clinical trial showed that PBD should not be performed routinely. PBD for patients with a distal biliary obstruction is leading to more serious complications compared with early surgery. Arguments for PBD have shifted from a potential therapeutic benefit towards a logistic problem such as patients suffering from cholangitis and severe jaundice at admission or patients who need extra diagnostic tests, or delay in surgery due to a referral pattern or waiting list for surgery as well as candidates for neoadjuvant chemo(radio)therapy. If drainage is indicated in these patients it should be performed with a metal stent to reduce complications after the drainage procedure such as stent occlusion and cholangitis. Considering a change towards more neoadjuvant therapy regimes improvement of the quality of the biliary drainage concept is still important.

    We evaluated the efficacy and safety of obeticholic acid (OCA, α-ethylchenodeoxycholic acid) in a randomized controlled trial of patients with primary biliary cirrhosis who had an inadequate response to ursodeoxycholic acid therapy. We performed a double-blind study of 165 patients with primary biliary cirrhosis (95% women) and levels of alkaline phosphatase (ALP) 1.5- to 10-fold the upper limit of normal. Patients were randomly assigned to groups given 10 mg, 25 mg, or 50 mg doses of OCA or placebo, once daily for 3 months. Patients maintained their existing dose of ursodeoxycholic acid throughout the study. The primary outcome was change in level of ALP from baseline (day 0) until the end of the study (day 85 or early termination). We also performed an open-label extension of the trial in which 78 patients were enrolled and 61 completed the first year. OCA was superior to placebo in achieving the primary end point. Subjects given OCA had statistically significant relative reductions in mean ALP from baseline to the end of the study (P ursodeoxycholic acid. The incidence and severity of pruritus were lowest among patients who received 10 mg/d OCA. Biochemical responses to OCA were maintained in a 12-month open-label extension trial.

  10. Update on Primary Biliary Cirrhosis

    Directory of Open Access Journals (Sweden)

    Jenny Heathcote

    2000-01-01

    Full Text Available The diagnosis of primary biliary cirrhosis (PBC is most often made in the asymptomatic phase, sometimes before the development of abnormal liver biochemistry. The antimitochondrial antibody remains the predominant hallmark, although not all patients test positive, even when the most sensitive techniques are used. The etiology of PBC remains elusive; studies suggest that the interlobular bile duct destruction is immune based, and associated autoimmune diseases are common. There are no surrogate markers that predict outcome in asymptomatic patients, whose chance of survival is less than that of age- and sex-matched populations but much better than the median survival of eight years in patients with symptomatic PBC. Symptoms common in this disease are fatigue, pruritus and xanthelasma, as well as complications of portal hypertension and osteoporosis. Treatment includes symptomatic and preventive measures, as well as specific therapeutic measures. Immunosuppressive therapy has yielded disappointing results in the long term management of PBC, and the only therapy shown to improve survival is the hydrophobic dihydroxy bile acid ursodeoxycholic acid. Treatment at a dose of 13 to 15 mg/kg/day is optimal, given in separate doses or as a single dose at least 4 h from giving the oral anion exchange resin cholestyramine, which may be used to control pruritus. However, liver transplantation remains the only cure for this disease, and the best postoperative survival is seen in patients whose serum bilirubin does not exceed 180 µmol/L at the time of liver transplantation. Recurrence takes place but is rarely symptomatic and does not deter from the benefits of transplantation.

    2014-08-01

    Full Text Available Primary biliary cirrhosis (PBC is a chronic progressive autoimmune disease characterized by portal inflammation and immune-mediated destruction of the intrahepatic bile ducts. Primary Sjögren's syndrome is an autoimmune disease characterized by lymphocytic infiltration of exocrine glands, mainly the lachrymal and salivary glands, in the absence of other definitively diagnosed rheumatologic disease. We report a diagnosed case of primary Sjögren's syndrome associated with PBC. A 59-year-old Caucasian woman went to oral evaluation reporting dry mouth, difficulty in eating associated with burning mouth syndrome, dysgeusia and dysphagia. Intraoral examination revealed extensive cervical caries, gingivitis, gingival retraction, angular cheilitis and atrophic tongue. Hyposalivation was detected by salivary flow and Schirmer's test was positive. Antinuclear and antimitochondrial antibodies were both positive. Anti-Ro/SSA and anti-La/SSB antibodies were negative. A minor salivary gland biopsy of the lower lip was performed. Histopathologic analysis revealed lymphocytic infiltrate with destruction of salivary gland architecture in some areas and replacement of glandular tissues by mononuclear cells. Optimal management of PBC associated with Sjögren's syndrome requires a multidisciplinary approach as the key to optimal patient care. Dental practitioners should be able to recognize the clinical features of this associated condition. Appropriate dental care may prevent tooth decay, periodontal disease and oral infections as well as improve the patient's quality of life.

    Despite the clinical significance of liver metastases, the difference between molecular and cellular changes in primary colorectal cancers (CRC) and matched liver metastases is poorly understood. In order to compare gene expression patterns and identify fusion genes in these two types of tumors, we performed high-throughput transcriptome sequencing of five sets of quadruple-matched tissues (primary CRC, liver metastases, normal colon, and liver). The gene expression patterns in normal colon and liver were successfully distinguished from those in CRCs; however, RNA sequencing revealed that the gene expression between primary CRCs and their matched liver metastases is highly similar. We identified 1895 genes that were differentially expressed in the primary carcinoma and liver metastases, than that in the normal colon tissues. A major proportion of the transcripts, identified by gene expression profiling as significantly enriched in the primary carcinoma and metastases, belonged to gene ontology categories involved in the cell cycle, mitosis, and cell division. Furthermore, we identified gene fusion events in primary carcinoma and metastases, and the fusion transcripts were experimentally confirmed. Among these, a chimeric transcript resulting from the fusion of RNF43 and SUPT4H1 was found to occur frequently in primary colorectal carcinoma. In addition, knockdown of the expression of this RNF43-SUPT4H1 chimeric transcript was found to have a growth-inhibitory effect in colorectal cancer cells. The present study reports a high concordance of gene expression in the primary carcinoma and liver metastases, and reveals potential new targets, such as fusion genes, against primary and metastatic colorectal carcinoma.

    In order to study the patency, restenosis, efficacy, and complication of the metallic stent in the course of treatment of malignant biliary obstruction, the results of follow up of the dead patients after stent insertion were reviewed. Self-expandable Gianturco metallic stent with 10-mm diameter was successfully inserted in 33 patients: 10 with Klatskin tumor, 7 with common bile duct cancer, 7 with gallbladder cancer, 5 with pancreatic cancer, 2 with recurred stomach cancer, one with periampullary cancer, one with hepatocellular carcinoma. The overall duration of survival and patency of the stents in 33 patients were 5.2 months(1-12 months) and 4.9 months(1-14 months), respectively. Restenosis of metallic stents was found in 9 cases(27%), after 6.1 months in average. Causes of stent occlusion were overgrowing of tumor in 5, overgrowing and ingrowing of tumor in 3, extraductal dislodgement in one case. Two cases of symptomatic cholangitis after stent placement were successfully treated with percutaneous cholecystostomy. Three cases of destruction and migration of metallic stents were found after 6 months. On the basis of our experience, insertion of Gianturco metallic biliary stent is an acceptable treatment method in the malignant biliary obstruction, especially for whom short term survival is expected.

    1984-11-01

    Tumor debris, free-floating in the major biliary ductal system, is a cause of intermittent biliary obstruction that has previously not been recognized. Six patients had hepatic neoplasms with episodic jaundice and/or cholangitis due to floating tumor debris. Diagnosis included metastatic adenocarcinoma of the colon (n = 3), cholangiocarcinoma (n = 1), hepatocellular carcinoma (n = 1), and cavernous hemangioma (n = 1). All patients underwent biliary exploration, with hepatic resection and transhepatic intubation in two and T-tube placement in four. One patient died in the early postoperative period, and the major complication rate in the five survivors was 0%. Four of the five survivors had no further episodes suggestive of major bile duct obstruction. Our experience emphasizes the importance of distinguishing extrahepatic obstruction secondary to tumor debris from the more common causes of jaundice in patients with tumors and suggests that safe and effective palliation can be achieved in these patients.

    Biliary enhanced MRI (BEMRI) by Gd-DTPA via PTCD and/or PTGBD tube for obstructive jaundice was performed in 8 patients. In all cases, biliary tract was clearly visualised as high signal intensity on T1 weighted images. On same images, primary lesion such as common bile duct cancer was also visualised as well as portal system. In addition, MR angiography (MRA) by 2D-time of flight method was performed. MRA with BEMRI shows portal encasement on the same image as biliary tract obstruction. This suggests MRA with BEMRI may replace the other modality for obstructive jaundice. (author)

    Invasive lobular carcinoma of the breast is the second most common type of primary breast cancer, accounting for 8-14% of cases, but is often difficult to diagnose early. It typically shows a diffuse pattern of infiltration within the breast, resulting in a variety of often subtle radiological appearances. A similar infiltrative pattern is seen in its metastatic form, with involvement of the gastrointestinal tract, peritoneum, retroperitoneum, bone marrow, meninges and uterus occurring more frequently than with the more common infiltrating ductal carcinoma of the breast. This pictorial essay illustrates the spectrum of radiological appearances which may be encountered with both primary and secondary lobular carcinoma. Harake, M.D.J., Maxwell, A.J. and Sukumar, S.A.

    Full Text Available The association between microscopic polyangiitis (MPA and primary biliary cirrhosis (PBC has seldom been reported. We describe here a patient who presented with sensorimotor neuropathy along with hypothyroidism, renal failure and liver dysfunction. Detection of antinuclear antibodies at a titer of 1/800, anti-SSA, anti-SSB, anti-GP210, anti-microsomial and p-ANCA anti-myeloperoxydase antibodies along with renal, salivary and liver biopsy led to a diagnosis of MPA associated with PBC, Sjogren′s syndrome and Hashimoto′s thyroiditis.

    Aberrant expression of E-cadherin has been associated with the development of metastases in patients with breast cancer. Even though the expression of E-cadherin has been studied in primary breast tumors, little is known about its expression at the distant metastatic sites. We investigate the relationship between E-cadherin expression in primary breast carcinoma and their distant, non-nodal metastases. Immunohistochemical analysis of E-cadherin was performed in tissues from 30 patients with primary invasive breast carcinoma and their distant metastases. E-cadherin expression was evaluated as normal or aberrant (decreased when compared with normal internal positive controls, or absent). Twenty-two (73%) invasive carcinomas were ductal, and eight (27%) were lobular. Of the primary invasive ductal carcinomas, 55% (12/22) had normal E-cadherin expression and 45% (10/22) had aberrant expression. All of the metastases expressed E-cadherin with the same intensity as (12 tumors) or with stronger intensity than (10 tumors) the corresponding primaries. Of the invasive lobular carcinomas, one of eight (12%) primary carcinomas and none of the metastases expressed E-cadherin in the cell membranes, but they accumulated the protein in the cytoplasm. Aberrant E-cadherin expression is frequent in invasive ductal carcinomas that progress to develop distant metastases. Distant metastases consistently express E-cadherin, often more strongly than the primary tumor. Invasive lobular carcinomas have a different pattern of E-cadherin expression, suggesting a different role for E-cadherin in this form of breast carcinoma

    Urethral carcinoma in women is uncommon. This study was undertaken to evaluate the role of radiotherapy in the treatment of these tumors. The hospital records of 34 women with primary urethral carcinoma were retrospectively reviewed. There were 15 squamous cell carcinomas, 13 transitional cell carcinomas, and six adenocarcinomas. The primary tumor was >4 cm in size in eight patients, involved the proximal urethra in 19 and extended to adjacent organs in 22. Inguinal or iliac lymphadenopathy was present in nine patients. There were eight TNM stage I/II tumors, 11 stage III tumors and 15 stage IV tumors. Radiotherapy was administered only to the primary tumor in 15 patients, and to the primary tumor and regional lymph nodes in the remaining 19 patients. Brachytherapy with or without external radiation was used to treat the primary tumor in 20 patients. Tumor recurred in 21 patients. The 7-year actuarial overall and cause-specific survivals were 41 and 45%, respectively. Large primary tumor bulk and treatment with external beam radiation alone (no brachytherapy) were independent adverse prognostic factors for local tumor recurrence. Brachytherapy reduced the risk of local recurrence by a factor of 4.2. The beneficial effect of brachytherapy was most prominently seen in patients with bulky primary disease. Large tumor size was the only independent adverse predictor of overall disease recurrence and death from cancer. Radiotherapy is an effective treatment for carcinoma of the female urethra and preserves normal anatomy and function. Brachytherapy improves local tumor control, possibly as a result of the higher radiation dose that can safely be delivered. (author)

    Primary neuroendocrine carcinoma of the breast is a very rare malignant tumor. There are not many cases reported in the English literature since it was first documented in 1983. Reports on the imaging features, in particular the ultrasonographic features of this rare tumor are scarce. Herein, we report a case of aggressive primary infiltrating neuroendocrine carcinoma of the breast, masquerading as an inflammatory breast condition in a 22-year-old young lady, perhaps the youngest case ever reported in the English literature. We discuss the imaging features and highlight the Doppler ultrasonographic findings of this rare breast carcinoma. This is the first documentation on Doppler ultrasonographic findings of primary neuroendocrine carcinoma of the breast in the literature

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

    Primary signet-ring carcinoma is a very aggressive and rare variant of a primary urinary bladder cancer, accounting for less than 1% of cases. We reported on a 76-year-old patient with primary signet-ring carcinoma who occurred metastatic lymphadenopathy with extranodal invasion causing intraluminal tumor thrombi in the adjacent vein, and pulmonary metastasis over the course of three months. We demonstrated the computed tomography findings of primary signet-ring carcinoma of the bladder and correlated the imaging findings with the pathologic features. We reviewed the distinguishing imaging findings of the primary signet-ring carcinoma compared with urothelial cell carcinoma, the most common subtype of the bladder cancer.

    Full Text Available Ahmad H Ali,1 Thomas J Byrne,1 Keith D Lindor1,21Division of Gastroenterology and Hepatology, Mayo Clinic, 2College of Health Solutions, Arizona State University, Phoenix, AZ, USAAbstract: Primary biliary cirrhosis (PBC is a chronic progressive liver disease that often leads to fibrosis, cirrhosis, and end-stage liver disease. The diagnosis is made when there is evidence of cholestasis and reactivity to the antimitochondrial antibody. The etiology of PBC is poorly understood; however, several lines of evidence suggest an environmental factor that triggers a series of immune-mediated inflammatory reactions in the bile ducts in a genetically susceptible individual. Fatigue and pruritus are the most common symptoms of PBC; however, many patients are diagnosed with PBC only based on laboratory abnormalities. The only pharmacological treatment approved for PBC is ursodeoxycholic acid (UDCA. Several controlled studies have shown that UDCA improves liver biochemistries and prolongs transplant-free survival in PBC patients. Nearly 40% of PBC patients do not respond to UDCA, and those patients are at high risk of serious adverse events, such as the development of liver failure. Therefore, newer alternative therapeutic options for PBC are needed. Obeticholic acid is a first-in-class farnesoid X receptor agonist that has been recently evaluated in PBC patients with inadequate response to UDCA, and demonstrated beneficial results in improving liver biochemistries. Several other agents (fibrates and glucocorticoids have been previously examined in PBC patients with inadequate response to UDCA, and preliminary results showed biochemical improvement. However, large-scale controlled clinical trials are needed to determine the long-term effects of fibrates and glucocorticoids on the clinical outcomes of PBC.

    The major causes of benign biliary strictures include surgery, chronic pancreatitis, primary sclerosing cholangitis, and autoimmune cholangitis. Biliary leaks mainly occur after surgery and, rarely, abdominal trauma. These conditions may benefit from a nonsurgical approach in which endoscopic retrograde cholangiopancreatography (ERCP) plays a pivotal role in association with other minimally invasive approaches. This approach should be evaluated for any injury before deciding about the method for repair. ERCP, associated with peroral cholangioscopy, plays a growing role in characterizing undeterminate strictures, avoiding both unuseful major surgeries and palliative options that might compromise any further management.

    Adenosquamous carcinoma, a rare malignant tumor of the stomach, is characterized by the presence of two different cell components, one adenomatous and the other squamous. Adenosquamous carcinoma of the stomach tends to more aggressive clinicopathologic features than common adenocarcinoma. There are few reports about radiologic features of adenosquamous carcinoma of the stomach. We experienced a case of a primary adenosquamous carcinoma of the stomach in a 67-year-old man, and report here the ultrasonographic and computed tomographic (CT) findings

    Background & Aims Coffee consumption has been associated with decreased risk of liver disease and related outcomes. However, coffee drinking has not been investigated among patients with cholestatic autoimmune liver diseases, primary biliary cirrhosis (PBC), or primary sclerosing cholangitis (PSC). We investigated the relationship between coffee consumption and risk of PBC and PSC in a large North American cohort. Methods Lifetime coffee drinking habits were determined from responses to questionnaires from 606 patients with PBC, 480 with PSC, and 564 healthy volunteers (controls). Patients (those with PBC or PSC) were compared to controls utilizing the Wilcoxon rank sum test for continuous variables and c2 method for discrete variables. Logistic regression was used to analyze the estimate the effects of different coffee parameters (time, frequency, and type of coffee consumption) after adjusting for age, sex, smoking status, and education level. Results Patients with PBC and controls did not differ in coffee parameters. However, 24% of patients with PSC had never drank coffee compared to 16% of controls (Pcoffee drinking coffee (46.6% vs 66.7% for controls, Pcoffee protected against proctocolectomy (hazard ratio=0.34, PCoffee consumption is lower among patients with PSC, but not PBC, compared to controls.

    International guidelines for managing osteoporosis in cirrhosis or severe cholestasis indicate a m. disodium clodronate 100mg every 10 days for 4 years. Ninety-six patients completed the study: 30 had a normal bone mineral density (group 1), 37 had osteopenia (group 2), 29 had osteoporosis (group 3). No significant differences in biochemical parameters of bone metabolism were observed between the three groups. A total of 288 bone mineral density measurements were taken. Linear regression analysis failed to reveal significant changes in t-score over the follow-up in all groups. A 4-year treatment with clodronate+calcium/vitamin D3 supplements does not significantly improve osteoporosis or osteopenia in primary biliary cirrhosis women in menopause, but prevents the natural bone loss in these patients. Extensive international trials are warranted to optimize the prevention and treatment of bone loss in primary biliary cirrhosis.

    Conventional plastic stents with a lumen typically have limited patency. The lumenless wing stent was engineered to overcome this problem. The objective of this study was to compare the incidence of early stent occlusion (symptomatic occlusion/cholangitis necessitating re-insertion within 90 days) for wing stents and conventional plastic stents. Patients with biliary pathology treated with plastic biliary stenting during the period 2003-2009 comprised the study cohort. Patients who had at least one biliary wing stent placed comprised the wing stent group, whereas patients who underwent only conventional stent plastic placement comprised the conventional stent group. Patients were stratified by indication: benign biliary strictures (group 1), malignant biliary strictures (group 2), or benign biliary non-stricture pathology (group 3). The association of stent type with the occurrence of primary outcome by indication was analyzed by use of multivariable logistic regression. Three-hundred and forty-six patients underwent 612 ERCP procedures with placement of plastic biliary stent(s). On multivariate analysis, early stent occlusion did not differ between the wing and conventional groups in groups 1, 2, and 3. Among patients who achieved primary outcome in group 2, significantly fewer patients in the wing group had cholangitis (6.7% vs. 39.1%, P = 0.03). Among patients who achieved primary outcome in group 3, significantly fewer patients in the wing group had cholangitis (10% vs. 50%, P = 0.03). Early stent occlusion was similar for wing stents and conventional plastic stents. Wing stents, however, were associated with a lower incidence of cholangitis in patients with malignant biliary obstruction and benign non-stricturing biliary pathology.

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

    Antimitochondrial antibodies (AMA) are the serologic cornerstone in the diagnosis of primary biliary cirrhosis (PBC), even if they are not detectable in a proportion of patients, notwithstanding the most sensitive and sophisticated technologies used. To fill in the serologic gap in AMA-negative PBC, there is sound evidence to consider antinuclear antibody (ANA) patterns, such as anti-multiple nuclear dots and anti-membranous/rim-like, as PBC-specific surrogate hallmarks of the disease, and their detection can be considered virtually diagnostic. Furthermore, particular ANA specificities, such as anti-gp210, anti-p62, anticentromere antibodies, and anti-dsDNA, may provide additional diagnostic and prognostic information.

    Acute suppurative cholangitis is a severe inflammatory process of the bile duct occurred as result of partial or complete obstruction of the bile duct, and may manifest clinically severe form of disease, rapidly deteriorating to life-threatening condition. We analyzed emergency percutaneous transhepatic biliary drainage in 20 patients of acute suppurative cholangitis with biliary sepsis to evaluate the therapeutic effect and complication of the procedure. The underlying cause were 12 benign disease(stones) and eight malignant tumors and among eight malignant tumors, bile duct stones(n=4) and clonorchiasis(n=1) were combined. Percutaneous transhepatic biliary drainage was performed successfully in 17 of 20 patients resulting in improvement of general condition and failed in three patients. The procedure were preterminated due to the patient's condition in two and biliary-proto fistula was developed in one. After biliary decompression by percutaneous transhepatic biliary drainage, effective and successful elective surgery was performed in nine cases, which were seven biliary stones and two biliary cancer with stones. Our experience suggest that emergency percutaneous transhepatic biliary drainage is an initial and effective treatment of choice for acute suppurative cholangitis with sepsis and a safe alternative for nonsurgical treatment

    To evaluate the surgical diagnosis and treatment of primary hyperthyroidism complicated with occult thyroid carcinoma. Data of 51 cases of primary hyperthyroidism complicated with occult thyroid carcinoma admitted during January 2004 to November 2014 were analyzed retrospectively. The incidence of occult thyroid carcinoma was 5.03% in hyperthyroidism,and 47 cases (92.16%) were female. The preoperative diagnosis of all these 51 cases was primary hyperthyroidism and 11 cases were diagnosed thyroid carcinoma at the same time;25 cases were diagnosed thyroid carcinoma by frozen section and the remaining 26 cases were diagnosed by postoperative pathology. Finally,26 cases underwent subtotal thyroidectomy,4 cases underwent total thyroidectomy, and 21 cases underwent total thyroidectomy with lymphadenectomy. The tumor size ranged from 0.1 to 1.0 cm [mean:(0.63 ± 0.35) cm]. The lesions were less than or equal to 0.5 cm in 28 cases (54.9%). The follow-up lasted from 1 to 121 months [mean:(28.6 ± 22.7)months] in 43 patients,and all of them survived. Primary hyperthyroidism complicated with occult thyroid carcinoma is commonly found in female patients. Preoperative diagnosis is difficult. Ultrasound is the major examining method. Frozen section can increase the detection rate. The postoperative prognosis of hyperthyroidism complicated with occult thyroid carcinoma is satisfactory.

    2001-05-01

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

    Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease leading to bile duct strictures and fibrosis, and predisposing to cholangiocarcinoma (CCA). Biliary dysplasia is a known precursor of CCA. In our unit, PSC patients undergo regular surveillance with ERC and brush cytology (BC), and liver transplantation is an option in case with biliary dysplasia. We evaluated the risk factors for biliary dysplasia and CCA based on ERC imaging, BC and liver function tests. Seven hundred and eighty-eight ERCs were performed with BC for 447 PSC patients. ERC images were evaluated using the modified Amsterdam score, neutrophilic inflammation was assessed in BC, and liver function tests were collected. Ploidy analysis with DNA flow cytometry was performed in cases with advanced PSC or previous suspicious BC/aneuploidy. The endpoint was either a benign disease course (follow-up for ≥2.4 years after the latest ERC), benign histology, biliary dysplasia or CCA. Benign disease course was seen in 424/447 (including 23 cases with biliary dysplasia), and CCA in 17 (3.8%) patients. Gallbladder carcinoma/carcinoma in situ was diagnosed in three patients. Advanced ERC findings, male gender, suspicious BC, aneuploidy in flow cytometry, inflammation, and elevation of ALP, bilirubin, ALT, AST, GGT, CEA and CA19-9 represented significant risk factors for CCA in univariate analysis. PSC patients with advanced bile duct disease and elevated liver enzymes, CEA or CA19-9, inflammation or suspicious BC are most likely to develop CCA. These patients may benefit from surveillance with BC if early liver transplantation is possible.

    Biliary epithelial cells preferentially respond to various insults under chronic pathological conditions leading to reactively atypical changes, hyperplasia, or the development of biliary neoplasms (such as biliary intraepithelial neoplasia, intraductal papillary neoplasm of the bile duct, and cholangiocarcinoma). Moreover, benign biliary strictures can be caused by a variety of disorders (such as IgG4-related sclerosing cholangitis, eosinophilic cholangitis, and follicular cholangitis) and often mimic malignancies, despite their benign nature. In addition, primary sclerosing cholangitis is a well-characterized precursor lesion of cholangiocarcinoma and many other chronic inflammatory disorders increase the risk of malignancies. Because of these factors and the changes in biliary epithelial cells, biliary strictures frequently pose a diagnostic challenge. Although the ability to differentiate neoplastic from non-neoplastic biliary strictures has markedly progressed with the advance in radiological modalities, brush cytology and bile duct biopsy examination remains effective. However, no single modality is adequate to diagnose benign biliary strictures because of the low sensitivity. Therefore, understanding the underlying causes by compiling the entire clinical, laboratory, and imaging data; considering the under-recognized causes; and collaborating between experts in various fields including cytopathologists with multiple approaches is necessary to achieve an accurate diagnosis.

    2010-07-01

    Although cholesterol levels are elevated in patients with primary biliary cirrhosis (PBC), most PBC patients are not at increased risk of dying from atherosclerotic heart disease. There is, however, a subgroup, approximately 10%, who have additional disorders of lipid metabolism. They might benefit from a cholesterol-lowering agent. However, there is concern about using statins in patients with pre-existing liver disease. We therefore reviewed our experience with statins in a large cohort of PBC patients who were seen at Tufts Medical Center during the past decade. From January 1, 1996, until June 30, 2006, 603 patients with PBC were seen by one of us (M.M.K.). Fifty-eight were on statins and five were on ezetimibe. The mean duration of usage was 41 months (range 3-125 months). Alanine aminotransferase (ALT) levels were measured at 3-month intervals. Statins were well tolerated. No patient complained of muscle pain or weakness. There was no increase in ALT levels. ALT levels were slightly elevated at the time that statins were begun (41.7 +/- 25.1 U/l), and were normal at the last time these patients were seen (39.0 +/- 21.0 U/l) (P Statins are safe in PBC patients who might benefit from their use.

  6. Influence of the Biliary System on Biliary Bacteria Revealed by Bacterial Communities of the Human Biliary and Upper Digestive Tracts.

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

    Parathyroid carcinoma is a rare clinical entity, which represents one of the main reasons, why surgery should be performed in specialized centres. Preoperatively, it is very difficult to distinguish between benign and malignant hyperparathyroidism. During the years 1996-2016, we performed 2,220 operations in 2,075 patients with a diagnosis of primary hyperparathyroidism. Among these 2,220 operations, there were 16 operations for parathyroid carcinoma. These 16 operations, including reoperations, were performed in four patients. Two patients had no reoperation, but another 2 patients required 14 reoperations in total. Parathyroid carcinoma was described in 0.2% of all patients with a diagnosis of primary hyperparathyroidism. The number of operations was 0.73% of all operations of primary hyperparathyroidism in years 1996-2016. Prognosis of parathyroid carcinoma is quite favourable, patients evidence a long-term survival rate after the primary operation. However, every reoperation increases the number of possible complications, including recurrent laryngeal nerve injury. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

    2015-01-01

    Squamous cell carcinoma (SCC) arising from the wall of an odontogenic cyst (also known as primary intraosseous carcinoma) is a rare tumor which occurs only in jaw bones. This tumor was first described by Loos in 1913 as a central epidermoid carcinoma of the jaw. Primary intraosseous carcinomas (PIOC) may theoretically arise from the lining of an odontogenic cyst or de novo from presumed odontogenic cell rests. According to the new histological classification of tumors of the World Health Organization, odontogenic keratocyst is nowadays considered a specific odontogenic tumor and the PIOC derived from it is considered as a specific entity which is different from other PIOCs derived from the odontogenic cysts. The following report describes a case of such extremely rare entity that is primary intraosseous SCC of the mandible derived from an OKC in a 60-year-old male patient with brief review of literature.

    Full Text Available We report a case of primary small-cell carcinoma of the stomach in a 75-year-old man. The patient was admitted to our hospital with a 1-week history of intermittent tarry stool. An upper gastrointestinal examination revealed a large stage A2 ulcer in the greater curvature of the body of the stomach, and pathological findings from biopsy specimens revealed small-cell carcinoma. The tumor cells were small-sized, composed of hyperchromatic nuclei with scant cytoplasm, and stained positive for cytokeratin, synaptophysin, and chromogranin A. The patient was diagnosed with primary small-cell carcinoma of the stomach. He declined further evaluation and received palliative management. This is a rare carcinoma of the stomach, with aggressive manifestations and a poor prognosis. The mean survival of patients with primary gastric small-cell carcinoma is reported to be 7 months. The choice of treatment for this disease is still controversial. This rare gastric tumor should be listed in the differential diagnosis of gastric carcinoma in the elderly.

    Full Text Available Background and objective The aim of this study is to investigate the clinical characteristics of patients with primary bronchopulmonary carcinoma complicated with chronic obstructive pulmonary disease (COPD, and to optimize the early diagnoses in the coexistence of COPD and primary bronchopulmonary carcinoma. Methods The clinical data of 118 patients with COPD complicated with primary bronchopulmonary carcinoma were analyzed retrospectively, including age, sex, smoking history, smoking index, clinical symptoms and signs, pathological type, staging, metastasis site and lung function index. 120 patients with simple COPD were selected as control. Results The smoking rate (55.1% and smoking index ≥400 branch /year (90.8% of the patients with COPD complicated with primary bronchopulmonary carcinoma were higher than the simple COPD group (20.8%, 48.0%. The difference between the two groups was statistically significant (P0.05, while the incidence of hemoptysis, weight loss, chest pain, hoarseness, pleural effusion and atelectasis were significantly higher than those in simple COPD group (P0.05, but the diffusing capacity of carbon monoxide (DLCO of COPD patients complicated with primary bronchopulmonary carcinoma was lower than that of simple COPD patients (P<0.05 . In the COPD patients with primary bronchopulmonary carcinoma, squamous cell carcinoma was the most common pathological type (51.7%. Male patients were mainly squamous cell carcinoma (60.7%, while female patients with adenocarcinoma (69.0%. Conclusion COPD combined with primary bronchopulmonary carcinoma occurs in male smokers more. There is higher incidence of squamous cell carcinoma. When they are first diagnosed, most of them are advanced or located late, due to no specific clinical symptoms at the early stages. Periodic chest CT examination for COPD patients can help early diagnoses of primary bronchopulmonary carcinoma.

    To summarize the experience in diagnosis and treatment of congenital biliary duct cyst. Clinical data from 108 patients treated from 1980 to 2000 were analyzed retrospectively. Abdominal pain, jaundice and abdominal mass were presented in most pediatric patients. Clinical symptoms in adult patients were non-specific, resulting in delayed diagnosis frequently. Fifty-seven patients (52.7%) had coexistent pancreatic biliary disease. Carcinoma of the biliary duct occurred in 18 patients (16.6%). Ultrasonic examination was performed in 94 patients, ERCP in 46, and CT in 71. All of the patients were correctly diagnosed before operation. Abnormal pancreatobiliary duct junction was found in 39 patients. Before 1985, the diagnosis and classification of congenital biliary duct cyst were established by ultrasonography preoperatively and confirmed during operation. The main procedure was internal drainage by cyst-enterostomy. After 1985, the diagnosis was decided with ERCP and CT, the procedure was cyst excision with Roux-en-Y hepaticojejunostomy. In 1994, we used a new and simplified operative procedure to reduce the risk of malignancy of choledochal cyst. Retrograde infection of the biliary tract the major postoperative complication, could be controlled by the administration of antibiotics. The concept in diagnosis and treatment of congenital choledochal cyst has been changed greatly. CT and ERCP are of great help in the classification of the disease. Currently, cyst excision with Roux-en-Y hepaticojejunostomy is strongly recommended as the treatment of choice for patients with type I and IV cysts. Piggyback orthotopic liver transplantation is indicated for type V cysts (Caroli's disease) with frequently recurrent cholangitis, resulting in biliary cirrhosis.

    Full Text Available ObjectiveTo systematically evaluate the association between smoking and the risk of primary biliary cirrhosis (PBC from the perspective of evidence-based medicine. MethodsA literature search was performed in PubMed, EMBASE, CBM, CNKI, Wanfang Data, and VIP database to collect the case-control studies on the association between smoking and the risk of PBC published in the last two decades. Chinese search words were “吸烟”, “香烟”, “原发性胆汁性肝硬化”, “危险因素”, “队列研究”, and “病例对照研究”, and English search words were “smoking”, “cigarette”, “tobacco”, “risk factors”, “primary biliary cirrhosis”, “cohort studies”, and “case-control studies”. And then a meta-analysis was performed using Review Manager 5.2. The pooled odds ratio (OR and 95% confidence interval (CI were calculated, and the publication bias was analyzed by funnel plots. ResultsA total of 7 case-control studies involving 5459 subjects (2652 patients with PBC vs 2807 controls were included in the meta-analysis. The analysis results showed that smokers had a significantly higher risk of PBC compared with non-smokers (OR=1.49, 95% CI: 1.11-2.00, P=0.009. The geographical subgroup analysis results showed that there was a significant difference in the risk of PBC between non-smokers and smokers in North America (OR=1.57, 95% CI: 1.20-2.04, P=0.0008. However, there was no significant difference in the risk of PBC between non-smokers and smokers in Europe (OR=1.41, 95% CI: 0.73-2.73, P=0.31. ConclusionSmoking can increase the risk of PBC. However, it needs to be confirmed in high-quality prospective studies with larger samples because of the heterogeneity of current included studies.

    The role of RI imaging in the diagnosis of lesions of the liver, biliary tracts and gastrointestinal tracts are reviewed, and representative cases are shown. Liver scintigraphy was of value for the diagnosis of lesions limitted to the liver such as primary and metastatic liver cancer and inflammatory liver diseases. However, RI methods were less useful in the diagnosis of lesions of the biliary tracts and stomach. RI scintigraphy was more sensitive than angiography in the detection of Meckel's deverticulum, Ballet's esophagus, and gastrointestinal hemorrhage. (Tsunoda, M.)

  14. Celiac Disease Assocaited with Primary Biliary Cirrhosis in a Coast Salish Native

    1994-01-01

    Full Text Available A 41-year-old Coast Salish female was initially diagnosed with typical features of classical adult celiac disease. Clinical and pathological features of primary biliary cirrhosis were also present, along with a familial history of insulin-dependent diabetes. Later, childhood celiac disease was detected in a male first-degree relative with diabetes. These patients are the first reported natives in Canada with celiac disease, a disorder believed to be genetically based but dependent on environmental factors for its clinical expression. The recognition of a ‘new’ disease in the setting of an aboriginal population may reflect geographical and climatic factors that permitted subsistence of this culturally complex food-gathering society up until most recent historical times, followed by adaptation of this society to European-based agricultural methods, particularly wheat cultivation.

    1984-11-01

    To determine the computed tomographic (CT) characteristics of nonfunctioning islet cell carcinoma of the pancreas, the CT scans of 27 patients with that disease were reviewed. The pancreatic tumor was identified as a mass in 26 patients (96%) Of the 25 tumors evaluated with contrast enhancement, 20 became partially diffusely hyperdense relative to nearby normal pancreatic tissue. Hepatic metastases were identified in 15 patients (56%), regional lymphadenopathy in 10 (37%), atrophy of the gland proximal to the tumor in six (22%), dilatation of the biliary ducts in five (19%), and dilatation of the pancreatic duct in four (15%). The CT appearances of the nonfunctioning islet cell tumors were compared with those of 100 ordinary (ductal) pancreatic adenocarcinomas. Although the two types of tumors were sometimes indistinguishable, features found to be more characteristic of islet cell carcinoma included a pancreatic mass of unusually large size, calcification within the tumor, and contrast enhancement of either the primary tumor or hepatic metastases. Involvement of the celiac axis or proximal superior mesenteric artery was limited to ductal carcinoma.

    Primary biliary cirrhosis (PBC), which predominantly affects women, has been associated with various autoimmune diseases. Although hypothyroidism accompanying PBC is well documented, the concomitance of PBC and hyperthyroidism is rare. Herein, we report the case of a 62-year-old man who was diagnosed with PBC several years after the development of Graves' disease. This is the first case of a male patient developing PBC with Graves' disease. Both serum alanine aminotransferase levels and serum thyroid hormone levels were normalized after the administration of thiamazole for Graves' disease. However, the cholestatic liver enzyme abnormalities continued, indicating that the PBC was actualized by the administration of thiamazole. After starting ursodeoxycholic acid treatment, cholestatic liver enzyme abnormalities improved. Taken together, when a cholestatic pattern of liver enzymes is observed during follow-up for Graves' disease, an association between Graves' disease and PBC should be considered as a differential diagnosis.

    Full Text Available Primary peritoneal serous carcinoma (PPSC is a rare primary malignancy that diffusely involves the peritoneum, indistinguishable clinically and histopathologically from primary serous ovarian carcinoma. The origin of PPSC has not been well characterized. Here we present a case of PPSC diagnosed in ultrasonography-guided fine needle aspiration cytology (FNAC in a 76- old female presenting with ascites, abdominal pain, distension and constipation. PPSC is an unusual tumour but cytomorphology is distinctive enough to diagnose preoperatively. In the case report hereby described PPSC is an inoperable malignancy, hence chemotherapy and palliative care are the only offered treatment.

    To assess the presence of primary biliary cirrhosis, 15 patients at various histopathologic stages were studied by Tc-99m IDA hepatobiliary and/or Tc-99m colloid hepatic imaging. In the earlier stages (I and II), seven of eight patients (88%) showed uniform hepatic retention of Tc-99m IDA. Of seven patients in the same stage, however, four (57%) showed no abnormality on Tc-99m colliod imaging. In three of these four negative patients (75%), uniform hepatic retention of Tc-99m IDA was noted. In the later stages (III and IV), all seven patients showed decreased clearance with or without delayed tracer appearance in the intestine and prominent hepatic retention on Tc-99m IDA imaging; with Tc-99m colloid imaging there was enlargement of the spleen and increased activity in the spleen and bone marrow. Thus, Tc-99m IDA imaging is considered to be more useful in revealing this functional disorder at the earlier stage of primary biliary cirrhosis and in evaluating progression from an earlier to a later stage of disease. Tc-99m colloid imaging also effectively evaluated progression

    2015-01-01

    Full Text Available The SP100 family members comprise a set of closely related genes on chromosome 2q37.1. The widely expressed SP100 and the leukocyte-specific proteins SP110 and SP140 have been associated with transcriptional regulation and various human diseases. Here, we have characterized the SP100 family member SP140L. The genome sequence analysis showed the formation of SP140L gene through rearrangements of the two neighboring genes, SP100 and SP140, during the evolution of higher primates. The SP140L expression is interferon-inducible with high transcript levels in B cells and other peripheral blood mononuclear cells. Subcellularly, SP140L colocalizes with SP100 and SP140 in nuclear structures that are devoid of SP110, PML, or p300 proteins. Similarly to SP100 and SP140 protein, we detected serum autoantibodies to SP140L in patients with primary biliary cirrhosis using luciferase immunoprecipitation system and immunoblotting assays. In conclusion, our results show that SP140L is phylogenetically recent member of SP100 proteins and acts as an autoantigen in primary biliary cirrhosis patients.

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

    Biliary scintigraphy was used to examine 21 patients who had suspected non-iatrogenic biliary trauma. Seven patients (33%) had scintigraphic evidence of biliary leakage. Ultimately, surgical biliary repair was required for only three of these patients. Visualization of the gallbladder did not occur in eight trauma patients, but only one patient was shown to have cholecystitis. In this series, 16 patients had Tc-99m sulfur colloid scans that offered no significant advantage over cholescintigraphy in the detection of hepatic parenchymal defects. Biliary scintigraphy provides clinically useful information in cases both of blunt and penetrating trauma

    Full Text Available Prognostic evaluation of patients with primary biliary cirrhosis (PBC and how to improve the prognosis have attracted much attention. Further therapeutic regimens for PBC patients with poor prognosis has become the direction of clinical and scientific studies. This article summarizes the association between baseline indices and prognosis and prognostic evaluation of patients undergoing ursodeoxycholic acid (UDCA treatment, introduces the current status of UDCA combined with budesonide, fibrates, and obeticholic acid for patients with poor response to UDCA and the drugs being developed, and analyzes the influencing factors for prognosis and efficacy of UDCA. It is pointed out that prognosis and efficacy should be evaluated before and during UDCA treatment, and that therapeutic regimens should be adjusted in time to improve prognosis.

    Full Text Available Hepatoid carcinoma is a rare malignancy defined as extrahepatic primary alpha-fetoprotein-producing carcinoma morphologically resembling hepatocellular carcinoma. It is extremely rare in the lungs, with ambiguous pathological descriptions and variable prognosis. Herein, we present the case of a 66-year-old man with a primary pulmonary hepatoid carcinoma in his right upper lung who received complete curative surgical resection and adjuvant chemotherapy. No signs of recurrence or distant metastasis have been observed for 57 months postoperation. In addition, the literature is reviewed and the pathological diagnostic pitfalls are discussed.

    Full Text Available Abstract Background Carcinoma of the gallbladder (GBC clinically mimics benign gallbladder diseases and often escapes detection until advanced stage. Despite the frequency of cholecystectomy, diagnosis of GBC remains problematic in many situations. We sought to identify pathologic features that contribute to the difficulty in recognition of GBC. Methods We identified 23 patients (ranged from 45 to 86 years, male to female ratio 1:4.5 with carcinoma involving the gallbladder referred to an academic medical center over a period of 10 years for study. This includes 10 cases of primary GBC, 6 cases of metastatic tumor to gallbladder, 6 cases of directly invasive adenocarcinoma arising elsewhere in the biliary tree, and one case of unidentified origin adenocarcinoma. Primary tumors include adenocarcinoma not otherwise specified (NOS in 6 cases, papillary adenocarcinoma in 2 cases, and single cases of undifferentiated carcinoma and combined adenocarcinoma and neuroendocrine carcinoma (NEC. Metastatic tumors to gallbladder were from a wide range of primary sites, predominantly the gastrointestinal tract. Results These cases illustrate seven potential pitfalls which can be encountered. These include: 1 mistakenly making a diagnosis of adenocarcinoma of gallbladder when only benign lesions such as deeply penetrating Rokitansky-Aschoff sinuses are present (overdiagnosis, 2 misdiagnosing well-differentiated invasive carcinoma with minimal disease as benign disease (underdiagnosis, 3 differentiating between primary NEC of gallbladder and metastasis, 4 confusing primary mucinous adenocarcinoma of gallbladder with pseudomyxoma peritonei from a low grade appendiceal neoplasm disseminated to gallbladder, 5 confusing gangrenous necrosis related to cholecystitis with geographic tumoral necrosis, 6 undersampling early, grossly occult disease, and 7 misinterpreting extracellular mucin pools.

    Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease. It has a varied course of progression ranging from being completely asymptomatic to aggressive disease leading to cirrhosis and resulting in liver transplantation. In addition, symptoms can be debilitating and can have a major impact on quality of life. For decades, there was only one anti-cholestatic agent available to target this disease and that was only effective in around half of patients, with little or no effect on symptoms. With increasing understanding of the pathogenic mechanisms of PBC and potential targets for drug treatment, pharmaceutical companies have shown a greater interest in this rare disease. A large number of novel therapeutic molecules have been developed and are currently being evaluated. In this review article all the novel molecules in use and in trials targeting cholestasis and symptoms in PBC are discussed.

    Primary intraosseous carcinoma (PIOC) is a rare odontogenic carcinoma defined as a squamous cell carcinoma arising within a jaw having no initial connection with the oral mucosa, and presumably developing from residues of the odontogenic epithelium. A 56-year-old patient who complained of delayed healing after extraction of upper left central incisor visited our department. The conventional radiographs showed a bony destructive lesion with ill-defined margin and moth-eaten appearance. On the computed tomographic images, the lesion perforated the labial cortex of alveolar bone, elevated the left nasal floor superiorly, and perforated partially both nasal floor. The magnetic resonance images showed low signal intensity at T2 and T1 weighted images at the area and adjacent soft tissue. Histologically, there were irregular epithelial islands with cell atypia, nuclear hyperchromatism, pleomorphism, atypical mitosis. The final diagnosis was PIOC.

  9. Hepcidin is an antibacterial, stress-inducible peptide of the biliary system.

    Directory of Open Access Journals (Sweden)

    Pavel Strnad

    Full Text Available BACKGROUND/AIMS: Hepcidin (gene name HAMP, an IL-6-inducible acute phase peptide with antimicrobial properties, is the key negative regulator of iron metabolism. Liver is the primary source of HAMP synthesis, but it is also produced by other tissues such as kidney or heart and is found in body fluids such as urine or cerebrospinal fluid. While the role of hepcidin in biliary system is unknown, a recent study demonstrated that conditional gp130-knockout mice display diminished hepcidin levels and increased rate of biliary infections. METHODS: Expression and localization of HAMP in biliary system was analyzed by real time RT-PCR, in-situ hybridization, immunostaining and -blotting, while prohepcidin levels in human bile were determined by ELISA. RESULTS: Hepcidin was detected in mouse/human gallbladder and bile duct epithelia. Biliary HAMP is stress-inducible, in that it is increased in biliary cell lines upon IL-6 stimulation and in gallbladder mucosa of patients with acute cholecystitis. Hepcidin is also present in the bile and elevated prohepcidin levels were observed in bile of primary sclerosing cholangitis (PSC patients with concurrent bacterial cholangitis compared to PSC subjects without bacterial infection (median values 22.3 vs. 8.9; p = 0.03. In PSC-cholangitis subjects, bile prohepcidin levels positively correlated with C-reactive protein and bilirubin levels (r = 0.48 and r = 0.71, respectively. In vitro, hepcidin enhanced the antimicrobial capacity of human bile (p<0.05. CONCLUSION: Hepcidin is a stress-inducible peptide of the biliary epithelia and a potential marker of biliary stress. In the bile, hepcidin may serve local functions such as protection from bacterial infections.

    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. (orig.) [de

    2014-01-01

    Bile acid composition in fasting duodenal bile was assessed at entry and at 2 years in patients with primary biliary cirrhosis (PBC) enrolled in a randomized, double-blind, placebo-controlled trial of ursodeoxycholic acid (UDCA) (10–12 mg/kg/d) taken as a single bedtime dose. Specimens were analyzed by a high-pressure liquid chromatography method that had been validated against gas chromatography. Percent composition in bile (mean ± SD) for 98 patients at entry for cholic (CA), chenodeoxycholic (CDCA), deoxycholic (DCA), lithocholic (LCA), and ursodeoxycholic (UDCA) acids, respectively, were 57.4 ± 18.6, 31.5 ± 15.5, 8.0 ± 9.3, 0.3 ± 1.0, and 0.6 ± 0.9. Values for CA were increased, whereas those for CDCA, DCA, LCA, and UDCA were decreased when compared with values in normal persons. Bile acid composition of the major bile acids did not change after 2 years on placebo medication. By contrast, in patients receiving UDCA for 2 years, bile became enriched with UDCA on average to 40.1%, and significant decreases were noted for CA (to 32.2%) and CDCA (to 19.5%). No change in percent composition was observed for DCA and LCA. Percent composition at entry and changes in composition after 2 years on UDCA were similar in patients with varying severity of PBC. In patients whose bile was not enriched in UDCA (entry and placebo-treated specimens), CA, CDCA, DCA, and the small amount of UDCA found in some of these specimens were conjugated to a greater extent with glycine (52%–64%) than with taurine (36%–48%). Treatment with UDCA caused the proportion of all endogenous bile acids conjugated with glycine to increase to 69% to 78%, while the proportion conjugated with taurine (22%–31%) fell (P < .05). Administered UDCA was also conjugated predominantly with glycine (87%). PMID:10347103

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

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

    Purpose: To retrospectively evaluate the outcome after radical radiotherapy (RT) and surgical salvage and assess the risk of late toxicity for patients with primary subglottic squamous cell carcinoma treated at our center. Methods and Materials: Between 1971 and 1996, 43 patients with primary squamous cell carcinoma of the subglottis (35 men, 8 women) were treated with radical RT. All received megavoltage irradiation, most commonly to a dose of 50-52 Gy in 20 fractions during 4 weeks (39 patients). The median follow-up was 4.2 years. Results: Local control was achieved with RT alone in 24 (56%) of the 43 patients: 7 of 11 with T1, 8 of 12 with T2, 4 of 8 with T3, and 5 of 12 with T4. The 5-year actuarial local relapse-free rate was 52%. Subsequent local control was achieved in 11 of the 13 patients with failed RT and attempted surgical salvage, for an ultimate local control rate of 81.4% (35 of 43). The 5-year overall and cause-specific actuarial survival rate was 50.3% and 66.9%, respectively. No patients developed Grade 3 or 4 late radiation morbidity. Conclusion: These data support the use of primary RT in the treatment of patients with primary squamous cell carcinoma of the subglottis as an appropriate treatment approach providing an option for laryngeal conservation

    Primary intraosseous squamous cell carcinoma is an odontogenic tumour with aggressive behaviour usually noticed in 6th to 7th decades of life. The tumour is characterized by progressive swelling of the jaw, pain and loosening of teeth. Microscopically, the lesion is showing foci of keratinising cells separated by collagenous connective tissue stroma. A case of primary intraosseous squamous cell carcinoma of mandible arising de novo in a 40-year-old man is reported.

    Multiple malignant esophageal tumors of the same cell type are described. In the esophageal mucosa, widespread carcinomatous transformation may be observed and multicentric invasive squamous cell carcinomas may develop. The concomitance of two independent esophageal malignant neoplasms of different epithelial histogenesis is uncommon. Synchronous adenocarcinoma and squamous cell carcinoma of the esophagus is reported. Adenosquamous carcinoma of the esophagus is a rare tumor. Adenocarcinoma of the esophagus represents 10% of esophageal cancer. We report a case of a synchronous primary invasive adenosquamous carcinoma and adenocarcinoma of the esophagus. Both tumors were demonstrated radiographically. The peculiarity of this neoplastic association and the importance of complete radiographic esophageal evaluation in patients with one obvious obstructing tumor of the esophagus are emphasized.

    2002-07-01

    To investigate the problems of the Hanaro stent (Solco Intermed, Seoul, Korea) when used in the palliative treatment of patients with inoperable malignant biliary obstruction. Between January 2000 and May 2001, the treatment of 46 patients with malignant biliary obstruction involved percutaneous placement of the Hanaro stent. Five patients encountered problems during removal of the stent's introduction system. The causes of obstruction were pancreatic carcinoma (n=2), cholangiocarcinoma (n=2), and gastric carcinoma with biliary invasion (n=1). In one patient, percutaneous transhepatic cholangiography and stent insertion were performed as a one-step procedure, while the others underwent conventional percutaneous transhepatic biliary drainage for at least two days prior to stent insertion. A self-expandable Hanaro stent, 8-10 mm in deameter and 50-100 mm in lengh, and made from a strand of nitinol wire, was used in all cases. Among the five patients who encountered problems, breakage of the olive tip occourred in three, upward displacement of the stent in two, and improper expansion of the distal portion of the stent, unrelated with the obstruction site, in one. The broken olive tip was pushed to the duodenum in two cases and to the peripheral intrahepatic duct in one. Where the stent migrated during withdrawal of its introduction system, an additional stent was inserted. In one case, the migrated stent was positioned near the liver capsule and the drainage catheter could not be removed. Although the number of patients in this study was limited, some difficulties were encountered in withdrawing the stent's introduction system. To prevent the occurrence of this unusual complication, the stent should be appropriately expansile, and shape in the olive tip should be considered.

    In spite of the acquired experience with laparoscopic common bile duct exploration (LCBDE) for choledocholithiasis management, there is still a risk of biliary leakage of 5% to 15% following choledochotomy closure. We evaluate the usefulness of fibrin-collagen sealants to reduce the incidence of biliary fistula after laparoscopic choledochorrhaphy. We report a retrospective analysis of 96 patients undergoing LCBDE from March 2009 to March 2017, whose closure of the bile duct was completed by antegrade stenting and choledochorraphy or by performing a primary suture. The study population was divided into two groups according to whether they received a collagen-fibrin sealant covering the choledochorrhaphy or not, analyzing the incidence of postoperative biliary fistula in each group. Thirty-nine patients (41%) received a fibrin-collagen sponge while the bile duct closure was not covered in the remaining 57 patients (59%). The incidence of biliary fistula was 7.7% (3 patients) in the first group and 14% (8 patients) in the second group (P=.338). In patients who underwent primary choledochorraphy, the fibrin-collagen sealant reduced the incidence of biliary leakage significantly (4.5% vs. 33%, P=.020), which was a protective factor with an odds ratio of 10.5. Fibrin-collagen sealants may decrease the incidence of biliary fistula in patients who have undergone primary bile duct closure following LCBDE. Copyright © 2018 AEC.

    Purpose: To evaluate the clinical efficacy of the polyure-thane-covered Nitinol Strecker stent in the treatment of patients with malignant biliary obstruction.Methods: Twenty-three covered stents produced by us were placed in 18 patients with malignant biliary obstruction. Jaundice was caused by cholangiocarcinoma (n=5), pancreatic Cancer (n=6), gallbladder Cancer (n=4), metastatic lymph nodes (n=2), and tumor of the papilla (n=1).Resulrs: The mean patency period of the Stents was 37.5 weeks (5-106 weeks). Recurrent obstructive jaundice occurred in two patients (11%). Adequate biliary drainage over 50 weeks or until death was achieved in 17 of 18 patients (94.4%). Late cholangitis was observed in two patients whose stents bridged the ampulla of Vater. Other late severe complications were not encountered.Conclusion: Although more study is necessary, our results suggest the clinical efficacy of our covered Nitinol Strecker stent in the management of obstructive jaundice caused by malignant diseases.

    Biliary scintigraphy was used to examine 21 patients who had suspected non-iatrogenic biliary trauma. Seven patients (33%) had scintigraphic evidence of biliary leakage. Ultimately, surgical biliary repair was required for only three of these patients. Visualization of the gallbladder did not occur in eight trauma patients, but only one patient was shown to have cholecystitis. In this series, 16 patients had Tc-99m sulfur colloid scans that offered no significant advantage over cholescintigraphy in the detection of hepatic parenchymal defects. Biliary scintigraphy provides clinically useful information in cases both of blunt and penetrating trauma

    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.

    At present, although imaging diagnosis has been developed, most hilar bile duct cancer is still diagnosed at an advanced stage and its prognosis is generally poor. In hilar bile duct cancer, radiotherapy and other several therapies, for example-chemotherapy, arterial-infusion chemotherapy, photodynamic therapy, etc-are being performed for non-operative cases. But standard therapies for this cancer has not been established yet. On the other hand, metallic stents (MS) have been widely used to relieve biliary obstructions as an alternative to plastic prostheses and conventional drainage. The use of MS offers good palliation in hilar bile duct cancer, but patients selection is a key to obtain good results. In this article we reviewed previous studies and clinical trials regarding the anti-cancer therapy and biliary stenting for unresectable hilar bile duct cancer. And optimal therapeutic strategy for hilar bile duct cancer is proposed, primarily based on present views. (author)

    To evaluate risk factors for the recurrence of biliary stones after a percutaneous transhepatic biliary stone extraction. The procedures were performed on 339 patients between July 2004 and December 2008 (54 months). Medical records and images were retrospectively reviewed for 135 patients (mean age, 66.4 years; 83 men and 52 women) who had undergone follow-up for a mean of 13.2 months (range, 3-37 months). To evaluate risk factors for the recurrence of biliary stones, variables were evaluated with univariate and multivariate analyses. Variables included sex, age, stone location, number of stones, stone size, presence of a peripapillary diverticulum, application of antegrade sphincteroplasty, presence of a biliary stricture, largest biliary diameter before the procedure, and gallbladder status. Thirty-three of the 135 patients (24%) had recurrent symptomatic biliary stones and underwent an additional extraction. The mean time to recurrence was 17.2 months +/- 8.7. Univariate analysis of risk factors for recurrence of biliary stones demonstrated that location, number of stones, stone size, application of antegrade sphincteroplasty, presence of a biliary stricture, and biliary diameter were significant factors (P or =6; relative risk, 64.8; 95% confidence interval: 5.8, 717.6) and stone size (> or =14 mm; relative risk, 3.8; 95% confidence interval: 1.138, 13.231) were determined to be significant risk factors. The independent risk factors for recurrence of symptomatic biliary stones after percutaneous transhepatic biliary stone extraction were a stone size of at least 14 mm and the presence of at least six stones.

    Full Text Available Primary urethral carcinoma is a rare cancer, comprising <1% of all malignancies. The location of this lesion presents a certain dilemma of treatment between efficacy and quality of life. We report an 84-year-old male patient, with a history of chronic hepatitis C, hypertension, and transient ischemic accident, who presented with dysuria and acute urinary retention. The intravenous urography showed mild prostatic enlargement, but no stone or filling defect was noted in the upper urinary tract. On urethrocystoscopy, multiple papillary tumors were found at the pendulous urethra, and the pathology of biopsy confirmed urothelial carcinoma. The patient was admitted, and electroresection with fulguration of urethral tumors was performed owing to the patient's old age and poor performance status. Intraurethral and intravesical chemotherapy with mitomycin C was regularly given at the outpatient clinic. Recurrent urothelial carcinomas were noted twice in the first 2 years of follow up, and repeated transurethral resections were done. Unfortunately, liver cirrhosis with hepatocellular carcinoma was diagnosed last June, for which he received transcatheter arterial chemoembolization. No recurrence of urethral cancer has been found on semiannual cystoscopy in the past 3 years. Penile-preserving surgery is a reasonable surgical option for elderly primary urethral carcinoma patients with acceptable oncological outcome and good quality of life.

    Purpose: The aim of this retrospective study is to evaluate the role of T2-weighted MR imaging (MRI) and MR cholangiopancreatography (MRCP) findings in the diagnosis of primary biliary cirrhosis (PBC). Materials and methods: The following T2-weighted MRI and MRCP findings: segmental hepatic atrophy/hypertrophy, irregular liver surface, parenchymal lace-like fibrosis, rounded low signal intensity lesions centering portal vein branches (periportal halo sign), periportal hyperintensity (cuffing), splenomegaly, ascites, lymphadenopathy, venous collaterals, and the configuration of intrahepatic biliary ducts were reviewed for their diagnostic significance by two observers in 13 female patients (mean age: 49 years) with PBC. Discordant readings of the observers were resolved at consensus. Results: When parenchymal lace-like fibrosis and periportal halo sign were seen together the sensitivity of T2-weighted MR images was 69%. In six cases periportal hyperintensity (cuffing) and periportal halo sign were seen together. Segmental hypertrophy was present in nine patients and hepatic surface irregularity due to regenerative nodules were present in 10 patients. Lymphadenopathy was seen in 10, splenomegaly was seen in 5, collateral vascular structures were seen in 2 and minimal perihepatic free fluid was seen in 2 patients. MRCP images revealed various mild irregularity in the intrahepatic bile ducts in 8 patients and focal narrowing at the common bile duct level in 1 patient. Conclusion: MRI and MRCP may support the clinical and laboratory findings of PBC even in the early stages of the disease. MRI can also be a choice of method for the recommended prolonged follow up.

    Antibodies to caseinolytic protease P(177-194) (ClpP(177-194)) of the proteolytic subunit of the Clp complex of Escherichia coli (E. coli) are uniquely present in primary biliary cirrhosis (PBC). Molecular mimicry between the regulatory subunit ClpX and the principal T-cell epitope of pyruvate dehydrogenase complex (PDC-E2) in PBC, has been proposed to account for this. Since ClpP is highly conserved among bacteria we investigated whether the micro-organisms triggering these antibodies may be other than E. coli. E. coli ClpP(177-194) is homologous with ClpP peptides of Yersinia enterocolitica (YEREN) and Haemophilus influenzae (HAEIN). Enzyme linked immunosorbent assay (ELISA) reactivity to these peptides was tested in 45 patients with PBC, 44 pathological and 32 healthy controls. Reactivity to at least one of the ClpP peptides was observed in 21 (47%) PBC patients, 5.8% pathological and 3.1% healthy controls (PECOLI ClpP(177-194), alone or in association with YEREN and/or HAEIN peptides, compared to three (14.2%) reactive with YEREN, two (9.5%) with YEREN/HAEIN and one (4.7%) with HAEIN peptide. Simultaneous reactivity to homologous sequences was due to cross-reactivity as confirmed by competition ELISAs. The PBC-specificity of anti-microbial ClpP reactivity is confirmed: the questions as to primary trigger(s) and relevance to PBC pathogenesis remain open.

    2012-12-15

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

    In this study, 310 patients with benign biliary diseases, 20 with gallbladder cancer, and 8 with biliary tract carcinoma underwent spiral CT (SCT) scanning at cholangiography. Depiction rate of the shape of the conjunction site of the gallbladder and biliary tract was 27.5% by conventional intravenous cholangiography (DIC), 92.5% by ERC, and 90.0% by DIC-SCT. Abnormal cystic duct course was admitted in 14.1%. Multiplanar reconstruction by DIC-SCT enabled identification of the common bile duct and intrahepatic bile duct stone. Three-dimensional reconstruction of DIC-SCT was effective in evaluating obstruction of the anastomosis or passing condition of after hepatico-jejunostomy. Two-dimensional SCT images through PTCD tube enabled degree of hepatic invasion in bile duct cancer, and three-dimensional images were useful in grasping the morphology of the bile duct branches near the obstruction site. DIC-SCT is therefore considered a useful procedure as non-invasive examination of bile duct lesions. (S.Y.)

    2016-01-01

    We present here a case of a 42-year-old woman diagnosed with primary neuroendocrine carcinoma of the breast (NECB). We discuss the importance of histological criteria for primary neuroendocrine mammary carcinoma, established by WHO in 2003 and 2012. After an overview of different cases of primary neuroendocrine carcinoma of the breast published in the literature, we present information about differential diagnosis, prognostic factors, and surgical and adjuvant treatment. Prognosis of NECB is not different from that of other invasive breast carcinomas and the most important prognostic factor is tumor grade (G). There is no standard treatment and patients should be treated similarly to patients with invasive ductal carcinoma, NOS (not otherwise specified), whose choice of therapy depends on tumor's size, degree of differentiation, clinical stage, and hormonal status.

    Full Text Available Primary signet ring cell carcinoma of the appendix is a very rare neoplasm that usually presents with signs and symptoms of acute appendicitis and in particular with a right lower abdominal pain. Preoperative imaging detection of appendiceal adenocarcinoma has an important value because it may result in an appropriate surgical procedure. We report a rare case of primary signet ring cell carcinoma of the vermiform appendix in an 80-year-old man who was misdiagnosed on computed tomography (CT scan as acute appendicitis.

    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 candidiasis is rare and often confused with a pre-cancerous lesion, squamous cell carcinoma, or verrucous carcinoma. We report an extremely rare case of squamous cell carcinoma of the vocal cord following primary candidiasis. A 62-year-old man presented to our department reporting a 1-month history of hoarseness. He underwent laryngeal microscopic surgery for a presumptive diagnosis of glottic carcinoma. Histopathologic examination revealed candidiasis and scattered moderate dysplasia. He was treated with itraconazole for 4 weeks, and followed up without any recurrence of candidiasis. However, the 42-month follow-up examination revealed a focal whitish lesion on the right true vocal cord, and a repeat biopsy of this area revealed squamous cell carcinoma without evidence of candidiasis. The patient was treated with radiotherapy and remains well with no signs of tumor recurrence or candidiasis.

    Objectives To analyze the epidemiology and describe the prognostic indicators of patients with primary squamous cell carcinoma of the thyroid. Study Design and Setting Retrospective cohort study based on a national database. Methods The US National Cancer Institute's SEER registry (Surveillance, Epidemiology, and End Results) was reviewed for patients with primary squamous cell carcinoma of the thyroid from 1973 to 2012. Study variables included age, sex, race, tumor size, tumor grade, regional and distant metastases, and treatment modality. Survival measures included overall survival (OS) and disease-specific survival (DSS). Results A total of 199 cases of primary squamous cell carcinoma of the thyroid were identified. Mean age at diagnosis was 68.1 years; 58.3% were female; and 79.4% were white. Following diagnosis, 46.3% of patients underwent surgery; 55.7%, radiation therapy; and 45.8%, surgery with radiation therapy. Kaplan-Meier analysis demonstrated OS and DSS of 16% and 21% at 5 years, respectively. Median survival after diagnosis was 9.1 months. Multivariate Cox regression analysis showed that predictors of OS and DSS included age ( P Squamous cell carcinoma of the thyroid is a rare malignancy with a very poor prognosis. Surgical resection confers an overall survival benefit. Age, tumor grade, and tumor size are predictors of OS and DSS.

    We investigated the usefulness of hepatobiliary scintigraphy (HBS) for diagnosing biliary obstruction after curative hepatic resection with biliary-enteric anastomosis. The study population consisted of 54 patients who underwent surgery for benign (n=18) or malignant (n=36) biliary disease. We analysed 68 technetium-99m DISIDA scintigrams which were performed at least 1 month after the surgery (median: 9 months). Final diagnosis was made by operative exploration, other invasive radiological studies or clinical and radiological follow-up for at least 6 months after the surgery. Diagnostic accuracy was analysed according to the pretest likelihood of biliary obstruction. There were two total and 15 segmental biliary obstructions. In patients with symptoms of biliary obstruction and abnormal liver function, HBS always allowed correct diagnosis (two instances of total obstruction, seven of segmental obstruction and seven of non-obstruction). Among the patients with non-specific symptoms or isolated elevation of serum alkaline phosphatase, HBS diagnosed segmental biliary obstruction in seven of the eight instances, and non-obstruction in 22 of 23 instances. There were no cases of biliary obstruction and no false-positive results of HBS in 21 instances with no clinical signs or symptoms of biliary obstruction. The diagnostic sensitivity and specificity of HBS for biliary obstruction were 94% (16/17) and 97% (50/51), respectively. In conclusion, HBS is a highly accurate modality for the diagnosis of segmental biliary obstruction during long-term follow-up after hepatic resection with biliary-enteric anastomosis. (orig.)

    Full Text Available Small cell carcinoma of the bladder is a rare, aggressive, poorly differentiated neuroendocrine neoplasm accounting for only 0.3-0.7% of all bladder tumors. Since the tumor is very rare, pathogenesis is uncertain. Small cell carcinomas of the urinary bladder are mixed with classic urothelial carcinomas or adenocarcinomas of the bladder in 68% cases, making pure primary small cell carcinoma even a rarer entity. The unknown etiology and natural history of small cell carcinoma of the urinary bladder represent a challenge both to the pathologist and urologists for its diagnosis and treatment, respectively.

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

    Background and Purpose: In a retrospective study the role of radiation therapy for the treatment of primary tracheal carcinoma was investigated. Patients and Methods: Between 1984 and 1997, 25 patients with primary tracheal carcinoma were treated with external beam radiotherapy (17 squamous-cell carcinoma [SCC], 8 adenoid cystic carcinoma [ACC], median dose SCC 60 Gy, ACC 55 Gy). An additional brachytherapy boost was carried out in 10/25 patients (median dose SCC 18 Gy, ACC 15 Gy). Ten patients underwent operative treatment. Results: The median survival (Kaplan-Meier) for patients with SCC was 33 months (ACC 94.2). The 1-, 2- and 5-year survival rates (Kaplan-Meier) for patients with SCC were 64.7% (ACC 85.7%), 64.7% (ACC 85.7%), and 26% (ACC 85.7%). Patients with ACC and patients with a complete remission after treatment had a significantly better survival probability (log rank test, p [de

    Full Text Available Abstract Background The number of cases of tuberculosis as a complication in people with immunodeficiency, people on immunosuppressive therapy and among the immigrant population is increasing in Germany. However, tuberculous peritonitis rarely occurs without these risks, particularly in Germans. The incidence of tuberculous peritonitis in Germany is very low; tuberculosis of the intestinal tract was found in approximately 0.8 % of tuberculosis cases in 2004. The diagnosis of tuberculous peritonitis is often delayed on account of non-specific clinical symptoms. The absence of specific biological markers, long incubation times for cultures and non-specific radiographic or ultrasonographic signs increase the morbidity associated with this treatable condition. Case presentation We report a case of tuberculous peritonitis in a 73-year-old female German patient. Her medical history revealed primary biliary cirrhosis (PBC since 1992. On admission, she complained of abdominal pain, vomiting, ascites and peripheral edema. The patient has been in a seriously reduced general condition and had fever up to 39.6°C. A few weeks earlier, the patient was in another hospital with the same complaint. Inflammatory parameters were elevated, but the procalcitonin level was normal. Blood culture was always negative, as was the tuberculin test. Ultrasonography of the abdomen showed massive ascites with multiple septa. The patient underwent a computed tomography (CT scan of the abdomen which showed a thickened intestinal wall in the sigmoid colon and a pronounced enhancement of the peritoneum. Computed tomography scans of the lung showed only slight bilateral pleural effusion. Because of the anaesthetic and bleeding risk due to thrombocytopenia, laparoscopy was not immediately undertaken. The culture from ascites was positive for M.tuberculosis after three weeks. Conclusion In primary biliary cirrhosis patients with non-specific clinical symptoms, such as vomiting

    Thymic carcinoma is a rare, highly aggressive type of tumor that typically occurs in the anterior mediastinum. We describe the case of a 73-year-old man who presented with weakness, cough, dyspnea, anorexia, and weight loss. An echocardiogram showed an intrapericardial mass that occupied the space around the lateral walls of the left ventricle and distally compressed the right ventricle. Magnetic resonance imaging and a biopsy confirmed the presence of intrapericardial primary thymic carcinoma. The patient underwent surgical excision of the tumor and died of right ventricular rupture during the procedure. This case highlights the importance of considering thymic carcinoma whenever an otherwise unexplained intrapericardial mass is encountered.

    Full Text Available Primary infiltrating ductal carcinoma of the axillary breast is rare and has a high frequency of lymph node (LN involvement. We report a woman with primary infiltrating ductal carcinoma arising from the right axillary breast with metastasis to the contralateral chest wall. Excisional biopsy of the left chest wall nodule and the right axillary mass was carried out and both showed invasive ductal carcinomas histologically. The lesion of the right axillary mass arose from the breast tissue, rather than the LN. Further surgery proved the right axillary LN metastasis. After further review, a primary infiltrating ductal carcinoma of the right axillary breast with metastasis to axillary LNs and contralateral chest wall was diagnosed. The patient also received chemotherapy and radiation and there was no evidence of tumor recurrence after treatment. The present report demonstrated a rare case with uncommon manifestation. Lesions of uncertain origin around the periphery of the breast should be suspected for breast carcinoma.

    Biliary parasitosis is one of the important causes of biliary obstruction in endemic areas, however due to migration and travel the disease is known to occur in non endemic zones as well. The spectrum of biliary fascioliasis ranges from recurrent biliary colics to acute cholangitis. The long term complications are gall stones, sclerosing cholangitis and biliary cirrhosis. We describe fascioliasis as a cause of recurrent biliary colics in a young male necessitating multiple hospitalizations over a period of four years. Investigative profile had been non-contributory every time he was hospitalized for his abdominal pain prior to the current presentation. He never had cholangitis due to the worm in the common bile duct. It was only at endoscopic retrograde cholangiopancreatography (ERCP) biliary fascioliasis was discovered to be the cause of his recurrent biliary colics. After removal of the live Fasciola hepatica from the common bile duct he became symptom free and is attending our clinic for last 11 months now. Clinical spectrum of biliary fascioliasis is discussed in this report.

    Objective: To evaluate imaging features and clinical value of CT biliary virtual endoscopy in the detection of biliary calculus. Methods: Eighteen patients with biliary calculi underwent volume scanning using spiral CT (Hispeed Advantage CT/i GE ). All data were transferred to computer workstation, and CT biliary virtual endoscopy images with pseudocolor encoding were generated from the volumetric data using the Navigator Smooth soft-ware. All cases were proved by ultrasound, axial CT or operation. Results: Among 18 cases, gallstones were found 8 in cases, common bile duct stones in 2 cases, gallstones and bile duct stones in 6 cases. The stones were 0.3-3.2 cm in size. CT biliary virtual endoscopy correctly demonstrated the surface details of stones which were viewed from extra- or intraluminal orientation in a 3D fashion. The findings were consistent with those of US, CT or operation. Conclusion: The CT virtual biliary endoscopy is a further development of virtual endoscopy for observing biliary calculus from intra- and extra-luminal views and providing three dimensional information of stone

    Operative treatment offers the best chance for long term survival in lung cancer of early stage. In the same way surgery may be the most efficient treatment of lung metastases from tumors of extrapulmonary site. The preoperative investigations have to prove that in case of lung cancer this is restricted to one hemithorax and in lung metastases that these are restricted to the lungs exclusively. They also have to prove that the lung function allows adequate resection. This is mainly lobectomy and pneumonectomy, sometimes sleeve resection and rarely segmentectomy for primary lung cancers. Resection of metastases preferably is by wedge excision or enucleation. In bilateral lesions median sternotomy is the favoured approach to both lungs in a single session. Long term results in primary lung cancer depend on the tumor stage. As a rule of thumb by each step of tumor stage the 5-year-survival rate is cut to half. In regard to histology small cell undifferentiated carcinomas are considered surgical indications only in the very early stage and need to be treated by adjuvant chemotherapy. The operative mortality is correlated to the extent of resection and by average is higher for primary carcinoma of the lung because of the usually higher age level and additional pulmonary damage. Patients operated for pulmonary metastases, however, are in lower age range and due to less functional risks, the operative mortality in most series is between 0 and 3%. Early detection of lung cancer, i.e., immediate and expert exploration of suspicious X-ray findings or respiratory symptoms particularly in smokers and with asbestos exposed individuals will contribute to an increasing efficacy of surgical treatment.

    2009-10-01

    Full Text Available Carcinomatous meningitis (CM occurs in 3 to 8% of cancer patients. Patients present with a focal symptom, and multifocal signs are often found following neurological examination. The gold standard for diagnosis remains the demonstration of carcinomatous cells in the cerebrospinal fluid on cytopathological examination. Despite the poor prognosis, palliative treatment could improve quality of life and, in some cases, overall survival. We report on a patient who presented with vertigo, tinnitus and left-sided hearing loss followed by progressive diffuse facial nerve paralysis. Lumbar cerebrospinal fluid confirmed the diagnosis of CM. However, no primary tumor was discovered, even after multiple invasive investigations. This is the first reported case in the English-language medical literature of CM resulting from a carcinoma of unknown primary origin.

    In a series of 22 patients with primary invasive squamous cell carcinoma of the vagina (stage I through IVa), a radical irradiation was planned in 18 and a palliative in the remaining 4 patients. The 5-year survival rate, in the radically irradiated patients, was 10/18 for all stages, and 8/13 for patients of stage I. A vaginal boost irradiation did not seem to improve the results of external irradiation in patients of stage I. Severe adverse effects did not occur.

    This study aims to compare the clinical outcomes and costs between endoscopic biliary stenting (EBS) and percutaneous transhepatic biliary stenting (PTBS). We randomly assigned 112 patients with unresectable malignant biliary obstruction 2006 and 2011 to receive EBS or PTBS with self-expandable metal stent (SEMS) as palliative treatment. PTBS was successfully performed in 55 patients who formed the PTBS group (failed in 2 patients). EBS was successfully performed in 52 patients who formed the EBS group (failed in 3 patients). The effectiveness of biliary drainage, hospital stay, complications, cost, survival time and mortality were compared. Patients in PTBS group had shorter hospital stay and lower initial and overall expense than the BBS group (P PTBS group was significantly lower than in EBS group (3/55 vs 11/52, P = 0.0343). Late complications in the EBS group did not differ significantly from PTBS group (7/55 vs 9/52, P = 0.6922). The survival curves in the two groups showed no significant difference (P = 0.5294).

    Background and purpose: Surgical excision remains the standard and most reliable curative treatment for eyelid carcinoma, but frequently causes functional and cosmetic impairment of the eyelid. We therefore investigated the efficacy and safety of radiation therapy in eyelid carcinoma. Patients and methods: Twenty-three patients with primary carcinoma of the eyelid underwent radiation therapy. Sebaceous carcinoma was histologically confirmed in 16 patients, squamous cell carcinoma in 6, and basal cell carcinoma in 1. A total dose of 50-66.6 Gy (median, 60 Gy) was delivered to tumor sites in 18-37 fractions (median, 30 fractions). Results: All but 3 of the 23 patients had survived at a median follow-up period of 49 months. The overall survival and local progression-free rates were 87% and 93% at 2 years, and 80% and 93% at 5 years, respectively. Although radiation-induced cataracts developed in 3 patients, visual acuity in the other patients was relatively well preserved. There were no other therapy-related toxicities of grade 3 or greater. Conclusion: Radiation therapy is safe and effective for patients with primary carcinoma of the eyelid. It appears to contribute to prolonged survival as a result of good tumor control, and it also facilitates functional and cosmetic preservation of the eyelid. (orig.)

    Full Text Available Squamous cell carcinoma (SCC arising from odontogenic cyst lining is rare. The exact incidence of carcinoma arising in odontogenic cyst is unknown, but it is estimated to vary between 1 and 2/1000. The pathogenesis is unknown, but a long-standing inflammation and continuous intracystic pressure have been suggested as possible causative factors. Metastasis from these lesions is not common (< 20%, and most of the carcinomas are moderately to well differentiated. To qualify as a primary intraosseous carcinoma, there must be no initial connection with the oral mucosa, overlying skin, or antral or nasal mucosa. This paper presents a case of primary intraosseous carcinoma arising from odontogenic keratocyst in the anterior mandible with metastasis to left parotid lymph nodes.

    Biochemical response to ursodeoxycholic acid among patients with primary biliary cirrhosis remains variable, and there is no agreement of an ideal model. Novel assessment of response coupled to histologic progression was recently defined by the Toronto criteria. We retrospectively assessed transplant-free survival and clinical outcomes associated with ursodeoxycholic acid response to evaluate the Toronto criteria using a large North American cohort of PBC patients. Three hundred and ninety-eight PBC patients from the Mayo Clinic PBC Genetic Epidemiology Registry were assessed for ursodeoxycholic acid treatment and biochemical response per the Toronto criteria. Responders were defined by reduction in alkaline phosphatase to less than or equal to 1.67 times the upper normal limit by 2 years of treatment, whereas non-responders had alkaline phosphatase values greater than 1.67 times the upper normal limit. Probability of survival was estimated using the Kaplan-Meier method. Three hundred and two (76 %) patients were responders and 96 (24 %) were non-responders. Significantly more non-responders developed adverse events related to chronic liver disease compared to responders (hazard ratio (HR) 2.77, P = 0.001). Biochemical responders and early-stage disease at treatment start was associated with improved overall transplant-free survival compared to non-responders (HR 1.9) and patients with late-stage disease (HR 2.7) after age and sex adjustment. The Toronto criteria are capable of identifying ursodeoxycholic acid-treated primary biliary cirrhosis patients at risk of poor transplant-free survival and adverse clinical outcomes. Our data reveal that despite advanced disease at diagnosis, biochemical response per the Toronto criteria associates with improved overall transplant-free survival.

    To evaluate the role of palliative surgical treatment in patients with advanced pancreatic carcinoma. Study Design: Case series. Place and Duration of Study: Surgical Ward of Khyber Teaching Hospital, Peshawar, from January 2005 to January 2009. Methodology: The study included patients with pancreatic carcinoma admitted with advanced, unresectable carcinoma of the pancreas. Patients with resectable tumours and with previous history of gastric or biliary surgery were excluded. Palliative procedures were performed after assessment of the tumour and its confirmation as unresectable on ultrasound and CT scan + ERCP. Postoperatively all patients were referred to oncologist. Complications and mortality were noted. Results: There were 40 patients, including 24 males and 16 females with mean age 58.72 +- 6.42 years. The most common procedure performed was triple bypass in 21 (52.50%) patients followed by choledocho-, cholecysto-, hepaticoand gastro-jejunostomy in various combinations. Wound infection occurred in 7 patients and was more common in patients with co-morbidities. Biliary leakage occurred in 03 patients. Postoperative cholangitis occurred in 3 patients while 7 patients had minor leak from the drain site. Four patients developed UTI, while 5 patients had signs of delayed gastric emptying. Two patients had upper gastrointestinal bleeding. Three patients died due to septicemia and multiple organs failure. Rest of the patients were discharged in stable state. The mean hospital stay was 8.40 +- 3.48 days and median survival was 7.72 +- 2.39 months. Conclusion: Surgical palliation for the advanced carcinoma pancreas can improve the quality of life of patients and is associated with minimum morbidity and mortality. (author)

    Full Text Available Abstract Background Despite the fact that metastases are the leading cause of colorectal cancer deaths, little is known about the underlying molecular changes in these advanced disease stages. Few have studied the overall gene expression levels in metastases from colorectal carcinomas, and so far, none has investigated the peritoneal carcinomatoses by use of DNA microarrays. Therefore, the aim of the present study is to investigate and compare the gene expression patterns of primary carcinomas (n = 18, liver metastases (n = 4, and carcinomatoses (n = 4, relative to normal samples from the large bowel. Results Transcriptome profiles of colorectal cancer metastases independent of tumor site, as well as separate profiles associated with primary carcinomas, liver metastases, or peritoneal carcinomatoses, were assessed by use of Bayesian statistics. Gains of chromosome arm 5p are common in peritoneal carcinomatoses and several candidate genes (including PTGER4, SKP2, and ZNF622 mapping to this region were overexpressed in the tumors. Expression signatures stratified on TP53 mutation status were identified across all tumors regardless of stage. Furthermore, the gene expression levels for the in vivo tumors were compared with an in vitro model consisting of cell lines representing all three tumor stages established from one patient. Conclusion By statistical analysis of gene expression data from primary colorectal carcinomas, liver metastases, and carcinomatoses, we are able to identify genetic patterns associated with the different stages of tumorigenesis.

    Objective: To investigate MRI examination methods and imaging manifestations of primary ureteral carcinoma, and to evaluate its clinical values when comparing with other diagnostic imaging facilities. Methods: Eighty-seven cases of primary ureteral carcinoma who were operated within recent 8 years came into the study, among which, 35 cases had MRI examinations. For MRI examination, coronal heavy T 2 WI (water imaging) was performed to show the dilated ureter, then axial T 2 WI and T 1 WI were scanned at the obstruction level. 11 cases underwent additional Gd-DTPA dynamic contrast enhanced scans. The original pre-operative diagnostic reports of various imaging facilities were analyzed comparing with the results of operation and pathology. Results: MRI showed ureteral dilatation in 33 of 35 cases, no abnormal appearance in 1 case, and only primary kidney atrophy post renal transplantation in 1 case. Among the 33 cases with ureteral obstruction, soft mass at the obstruction level was detected on axial scans in 32 cases. The lesions showed gradual and homogeneous mild to moderate enhancement on contrast MRI. The overall employment rate of imaging facilities was as follows: ultrasound (94.3%), IVU (59.8%), CT (52.9%), MRI (40.2%), and RUP (35.6%). The accurate diagnostic rate was as follows :MRI (91.4%), RUP (80.6%), CT (63.0%), ultrasound (47.6%), and IVU (11.5%). Conclusion: Combination of MR water imaging and conventional sequences can demonstrate most primary ureteral carcinoma lesions and has a highest diagnostic accuracy among the current diagnostic imaging facilities. It should be taken as the first diagnostic imaging method of choice when primary ureteral carcinoma is suspected after ultrasound screening

    Backgrounds and aims: Accurate assessment of graft bile duct is important to plan surgical procedure. Magnetic resonance cholangiopancreatography (MRCP) has become an important diagnostic procedure in evaluation of pancreaticobiliary ductal abnormalities and has been reported as highly accurate. We aim to estimate the efficacy of preoperative MRCP on depicting biliary anatomy in living donor liver transplantation (LDLT), and to determine whether inaccurate preoperative imaging assessment would increase the biliary complications after LDLT. Methods: The data of 118 cases LDLT were recorded. Information from preoperative MRCP was assessed using intraoperative cholangiography (IOC) as the gold standard. The possible risk factors of recipient biliary complications were analyzed. Results: Of 118 donors, 84 had normal anatomy (type A) and 34 had anatomic variants (19 cases of type B, 9 cases of type C, 1 case of type E, 2 cases of type F and 3 cases of type I) confirmed by IOC. MRCP correctly predicted all 84 normal cases and 17 of 34 variant cases, and showed an accuracy of 85.6% (101/118). The incidence of biliary complications was comparable between cases with accurate and inaccurate classification of biliary tree from MRCP, and between cases with normal and variant anatomy of bile duct. While cases with graft duct opening ≤5 mm showed a significant higher incidence of total biliary complications (21.1% vs. 6.6%, P = 0.028) and biliary stricture (10.5% vs. 1.6%, P = 0.041) compared with cases with large duct opening >5 mm. Conclusion: MRCP could correctly predict normal but not variant biliary anatomy. Inaccurate assessment of biliary anatomy from MRCP not increases the rate of biliary complications, while small-sized graft duct may cause an increase in biliary complications particularly biliary stricture after LDLT.

  4. Membranoproliferative glomerulonephritis in a carcinoma with unknown primary: An autopsy study

    Full Text Available Kidney disease frequently complicates malignancy and its treatment. Although many solid and hematologic cancers may involve the renal parenchyma, clinical sequelae are usually not prominent. Published reports cite membranous nephropathy as the most common malignancy-associated glomerulopathy, occurring with many carcinomas and occasionally with leukemia and lymphoma followed by minimal change disease. Rarely membranoproliferative glomerulonephritis (MPGN has been reported in patients with malignancy. The mechanism by which malignancy induces disease remains unproved, but may involve deposition of tumor antigen in the subepithelial space with in situ immune complex formation and subsequent complement activation. Treatment of the underlying malignancy may lead to resolution of nephrotic syndrome, lending indirect support to this theory. We report a rare autopsy case of a patient with metastatic carcinoma (with unknown primary associated with MPGN. The association between MPGN and metastatic carcinoma with unknown primary is uncommon and has not been previously reported in the literature.

    Full Text Available The detection of breast carcinoma cells in effusions is associated with rapidly fatal outcome, but these cells are poorly characterized at the molecular level. This study compared the gene array signatures of breast carcinoma cells in primary carcinomas and effusions. The genetic signature of 10 primary tumors and 10 effusions was analyzed using the Array-Ready Oligo set for the Human Genome platform. Results for selected genes were validated using PCR, Western blotting, and immunohistochemistry. Array analysis identified 255 significantly downregulated and 96 upregulated genes in the effusion samples. The majority of differentially expressed genes were part of pathways involved in focal adhesion, extracellular matrix-cell interaction, and the regulation of the actin cytoskeleton. Genes that were upregulated in effusions included KRT8, BCAR1, CLDN4, VIL2, while DCN, CLDN19, ITGA7, and ITGA5 were downregulated at this anatomic site. PCR, Western blotting, and immunohistochemistry confirmed the array findings for BCAR1, CLDN4, VIL2, and DCN. Our data show that breast carcinoma cells in primary carcinomas and effusions have different gene expression signatures, and differentially express a large number of molecules related to adhesion, motility, and metastasis. These differences may have a critical role in designing therapy and in prognostication for patients with metastatic disease localized to the serosal cavities.

    A 64-year-old man was transferred to our hospital because of indigestion and jaundice. The initial abdominal CT and MRI revealed a 2.0 cm enhancing mass in the proximal common bile duct (CBD) with several enlarged lymph nodes. The mass was presumed to be a cholangiocarcinoma, and a CBD segmental resection and choledochojejunostomy was performed. However, the final diagnosis was that of a mixed endocrine-exocrine carcinoma, a high-grade neuroendocrine neoplasm. Seven months after the operation, a follow-up abdominal CT study revealed multiple small arterial enhancing nodules in both hepatic lobes. A sono-guided liver biopsy confirmed these as metastastic mixed endocrine-exocrine carcinoma. This case is unique in that the imaging study regarding the neuroendocrine neoplasm of biliary duct has not been previously reported.

    Eight patients with undifferentiated carcinoma of the esophagus were treated by radiation therapy. Loco-regional control was easily achieved by radiation therapy alone and no loco-regional recurrence was observed for six patients treated with total dose of more than 30 Gy. However four patients developed distant metastases and died of tumor. Median survival was 3.5 months with a range of 0 to 48 months. Only one patient is alive with no evidence of tumor for 48 months. Combination chemotherapy should be recommended for primary undifferentiated carcinoma of the esophagus because of having a high incidence of distant metastases. (author)

  8. Metastatic Carcinoma Occurring in a Gastric Hyperplastic Polyp Mimicking Primary Gastric Cancer: The First Reported Case

    Full Text Available Hyperplastic polyps of the stomach are regarded as benign. However, in rare cases they may contain incipient primary carcinomas. To our knowledge, breast carcinoma metastatic to a gastric hyperplastic polyp has not yet been reported. We describe the case of a 69-year-old woman to whom a gastric polyp was endoscopically excised. The patient had previously undergone a right mastectomy for mixed, invasive ductal and lobular carcinoma 5 years earlier. Histological sections from the gastric lesion showed typical features of hyperplastic polyp with foci of poorly differentiated adenocarcinoma including signet ring cells infiltrating the lamina propria. The histologic findings were consistent with a primary gastric cancer. However, the carcinoma cells were immunopositive for estrogen and progesterone receptors and GATA3 and negative for CDX2, Hep Par 1, and MUC5AC. E-cadherin showed membranous reactivity in some of the carcinoma cells while in others it was negative. Accordingly, metastatic mixed, lobular and ductal breast carcinoma was diagnosed. We conclude that metastatic adenocarcinoma mimicking primary gastric cancer can be rarely encountered in hyperplastic gastric polyps.

    This investigation was undertaken to evaluate the relationship between Ga-67 uptake and radiotherapeutic response of primary lung cancer (squamous cell carcinoma), Ga-67 uptake of tumor was estimated on 16 patients with untreated primary lung cancer (squamous cell carcinoma). Ga-67 uptake was then compared with the response to radiation therapy (tumor reduction ratio). There was statistically significant inverse correlation between Ga-67 uptake and response to radiation therapy (r=-0.701, p<0.01). The fewer the Ga-67 accumulation in the tumor, the more effective radiotherapy in reducing tumor size. In conclusion, Ga-67 scintigraphy appears to be able to predict the response of primary lung cancer (squamous cell carcinoma) to radiation therapy. (author)

    Progressive lameness and leg pain were the predominant clinical signs in a 17-week-old male border collie presented for examination. On clinical investigation, extrahepatic cholestasis in association with rickets due to inadequate vitamin D resorption was diagnosed. The dog was treated parenterally with vitamin D and a cholecystoduodenostomy was performed. At 25 days postsurgery the lameness had resolved and bone structure was radiographically normal. However, at six weeks postsurgery, the dog's condition deteriorated rapidly and euthanasia was finally performed at eight weeks postsurgery. At postmortem examination, Toxocara canis nematodes were found to have invaded the biliary system via the anastomosis between the gallbladder and duodenum, causing biliary and hepatic toxocariasis. The cause of the primary extrahepatic cholestasis was atresia of the common bile duct at the hepatic end. The liver tissue showed microscopic lesions of chronic extrahepatic cholestasis as well as acute inflammation associated with the nematode invasion. There was no postmortem evidence of bone lesions. Extrahepatic biliary atresia is extremely rare in animals and has not been described before in dogs. In contrast, it represents the most common cause of congenital cholestasis in children, occurring in approximately one per 10,000 to 15,000 live births.

    Objective: To discuss the prevention and treatment of biliary complications occurred after CT-guided percutaneous radiofrequency ablation (RFA) for hepatic neoplasms. Methods: A total of 1136 patients, including 920 males and 216 females, with hepatic neoplasms were enrolled in this study. The hepatic tumors consisted of primary hepatocellular carcinoma (n=1037), hepatic metastasis (n=83) and hepatic cavernous hemangioma (n=16). The diameters of the tumors ranged from 0.5 to 16 cm. A total of 1944 RFA procedures were carried out in all patients. Results: Thirty-five patients developed biliary complication (35/1944, 1.80%). Twelve patients developed asymptomatic bile duct dilatation and no special treatment was given. Obstructive jaundice occurred in two patients and percutaneous transhepatic cholangiocholecystic drainage (PTCD) together with subsequent inner stent implantation had to be carried out. Eighteen patients developed biloma, and liver abscess formation secondary to biloma infection occurred in seven of them. Percutaneous transhepatic biloma drainage (PTBD) was adopted in all these patients. One patient suffered from obstructive jaundice complicated by biloma, and both PTCD and PTBD combined with inner stent implantation were simultaneously performed. One patient had the biloma secondary to obstructive jaundice, and PTCD followed by PTBD was conducted in turn. One patient developed obstructive jaundice secondary to biloma, and PTBD followed by PTCD was employed in turn. Conclusion: Obstructive jaundice and biloma are severe biliary complications occurred after CT-guided percutaneous radiofrequency ablation for hepatic tumors, and PTCD and/or PTBD should be carried out without delay to treat these complications. The clinical symptoms can be relieved, or even completely disappear, after treatment. (authors)

  12. An incidental primary papillary carcinoma arising in a thyroglossal duct cyst: Report of a rare finding

    2016-01-01

    Full Text Available The thyroglossal duct cysts (TGDCs are the most common congenital anomaly of the thyroid, usually manifested as painless midline neck mass. Malignancy is very rare and is reported in around 1% of cases as an incidental finding after histopathological evaluation of resected cyst. Papillary carcinoma is the most common carcinoma reported in TGDC. Here, we report a case of 17-year-old-female, who presented with a gradually increasing midline neck mass which moves with swallowing. On imaging a diagnosis of infected TGDC was made. The Sistrunk operation was done and a diagnosis of primary papillary carcinoma arising in a TGDC was rendered histopathologically. The contemporary appearance of papillary carcinoma thyroid was reported in about 20% cases of TGDC carcinoma, thus it is essential to differentiate primary papillary carcinoma arising in a TGDC from those of metastatic papillary carcinoma thyroid by strict diagnostic criteria.

    In order to detect and to evaluate the frequency, the distribution, and the radiological findings of skeletal metastases from hepatocellular carcinoma, the authors retrospectively analyzed radiographic, scintigraphic, and CT findings of 257 patients with hepatocellular carcinoma. The results were as follows: 1. Skeletal metastases were demonstrated in 21 patients (8.2%). 2. Frequent symptoms were pain, limitation of motion, paralysis, and mass. In nine of them the initial symptoms were due to skeletal metastases. 3. The common sites of metastases were spine (13 cases), ribs (8 cases), pelvis (8 cases) and femur (6 cases). Humerus, skull and sternum were also frequently involved. 4. Plain film findings were purely osteolytic in all cases and pathologic fractures were noted in 5 cases. 5. The lesions appear expansible in 7 cases, and 4 of them showed associated soft tissue masses on CT scans. 6. Bone scans were performed in 13 cases of them and showed increased radiotracer uptake in all. 7. Angiographic studies of 3 cases showed hypervascularity of the metastatic lesions as well as the primary hepatic tumor.

    We retrospectively evaluated 41 patients with metastatic cervical tumors from unknown primary sites at the Hyogo College of Medicine between 1997 and 2007. The N stage classification of cervical lymph nodes was: N1 in 3 cases, N2a in 10 cases, N2b in 10 cases, N2c in 4 cases, and N3 in 14 cases. The histopathological diagnoses of cervical lymph node were: squamous cell carcinoma in 33 cases, adenocarcinoma in 5 cases, undifferentiated carcinoma in 2 cases, and papillary carcinoma in 1 cases. Primary tumor sites were: tonsil in 5 cases, esophaguses in 2 cases, hypopharynxies in 2 cases, and thyroid, oral floor, submandibular gland, lung, gastric and colon in 1 case each. The useful tests were gastric endoscope, positron emission tomography-computed tomography (PET-CT), and blind biopsy of tonsil. We treated 24 of the 41 patients. Therapies were: neck dissection with postoperative radiation therapy in 11 cases, neck dissection alone in 1 case, only radiation or chemoradiation therapy alone in 8 cases, and chemotherapy alone in 4 cases. The 5-year survival rate was 40.1% in all cases and 81.5% in cases who underwent neck dissection. (author)

    Signet ring cell carcinoma, a subtype of adenocarcinoma, is a rare cause of primary lung cancer. The authors report a case of primary lung signet ring cell carcinoma presenting as a cavitary Pancoast tumor in a 32-year-old male smoker. Beyond the rarity of primary lung signet ring cell carcinoma itself, the youth of the patient, his smoking status, the presence of cavitation, and the location of the tumor in the superior sulcus make it especially atypical.

    Tumor-infiltrating lymphocytes and immune checkpoint proteins such as PD-L1 are potential prognostic factors and therapeutic targets in breast cancer. Most studies characterizing the breast tumor immune microenvironment have focused on ductal carcinomas. Here we investigate the tumor microenvironment of primary invasive lobular carcinomas. Previously constructed tissue microarrays of 47 lobular carcinomas were labeled by immunohistochemistry for PD-L1, CD8, CD20, and FoxP3. The stromal immune infiltrate density was qualitatively scored as a percentage of tumor area: 1+ (50%). The average immune cell subtype per high-power field was quantitatively scored. The percentage PD-L1 labeling on tumor-infiltrating lymphocytes was scored as none, focal (lobular carcinomas contained PD-L1 + tumor-infiltrating lymphocytes with the majority showing 1+ immune infiltrates with focal-moderate PD-L1 labeling. PD-L1 was expressed by tumor cells in 17% of lobular carcinomas. In contrast to ductal carcinomas, there was no correlation between the immune infiltrate density, the PD-L1 expression by lobular carcinoma cells, tumor grade, or the expression of estrogen receptor or human epidermal growth factor receptor-2. However, both the tumor-infiltrating lymphocyte density and the average CD8 + T-cell counts correlated with immune cell PD-L1 status (P=0.004 and 0.03, respectively). Similar to breast ductal carcinomas, PD-L1 + lobular breast carcinomas had higher numbers of PD-L1 + tumor-infiltrating lymphocytes (63%) than PD-L1 - lobular carcinomas (23%; P=0.04). These data show that a subset of primary breast lobular carcinomas both express PD-L1 on tumor cells and contain PD-L1 + tumor-infiltrating lymphocytes, suggesting the possibility of both constitutive and adaptive PD-L1 expression. Together, these results support immunotherapy as a potential treatment for a subset of patients with primary invasive lobular breast carcinomas.

    The differential diagnosis of facial anesthesia is vast. This may be secondary to trauma, neoplasm, both intracranial and extracranial, infection, and neurologic disease. When evaluating a patient with isolated facial anesthesia, the head and neck surgeon often thinks of adenoid cystic carcinoma, which has a propensity for perineural invasion and spread. When one thinks of head and neck squamous cell carcinoma with or without unknown primary, the typical presentation involves dysphagia, odynophagia, weight loss, hoarseness, or more commonly, a neck mass. Squamous cell carcinoma presenting as facial anesthesia and perineural spread, with no primary site is quite rare. Case presentations and review of the literature. Trigeminal anesthesia is an uncommon presentation of head and neck squamous cell carcinoma with unknown primary. We present two interesting cases of invasive squamous cell carcinoma of the trigeminal nerve, with no primary site identified. We will also review the literature of head and neck malignancies with perineural spread and the management techniques for the two different cases presented. Copyright © 2016 Elsevier Inc.

    To evaluate feasibility, safety, and outcome of patients treated with biodegradable biliary stents for benign biliary stenosis refractory to other treatments. Between March 2011 and September 2012, ten patients (seven men, three women; age 59 ± 7 years) with recurrent cholangitis due to postsurgical biliary stricture, previous multiple unsuccessful (two to five) bilioplasties, and unsuitability for surgical/endoscopic repair underwent percutaneous implantation of a biodegradable biliary stent. Patients were followed-up clinically and with ultrasound at 1, 3 and 6 months, and then at 6-month intervals. Stent implantation was always feasible. No immediate major or minor complications occurred. In all patients, 48-h cholangiographic control demonstrated optimal stent positioning and stenosis resolution. In a median follow-up time of 16.5 months (25th-75th percentiles = 11-20.25 months) no further invasive treatment was needed. Three patients experienced transient episodes of cholangitis. Neither re-stenosis nor dilatation of the biliary tree was documented during follow-up. No stent was visible at the 6-month follow-up. Percutaneous placement of biodegradable biliary stents represents a new option in treating benign biliary stenoses refractory to treatment with bilioplasty. This technique seems to be feasible, effective and free from major complications. Further investigations are warranted to confirm our preliminary results.

    Full Text Available Metastasis to the breast from an extra-mammary primary is a rare phenomenon; metastasis from gastric carcinoma to the breast is extremely so. We report a case who initially presented as mucin-secreting and signet-ring cell tumor of the ovary, and after an interval of 8 months with breast and chest wall metastatic nodules. The covert gastric primary eluded the oncologists at both presentations.

    Pancreaticobiliary maljunction (PBM) is a congenital malformation in which the pancreatic and bile ducts join anatomically outside the duodenal wall. Japanese clinical practice guidelines on how to deal with PBM were made in 2012, representing a world first. According to the 2013 revision to the diagnostic criteria for PBM, in addition to direct cholangiography, diagnosis can be made by magnetic resonance cholangiopancreatography (MRCP), 3-dimensional drip infusion cholangiography computed tomography, endoscopic ultrasonography (US), or multiplanar reconstruction images by multidetector row computed tomography. In PBM, the common channel is so long that sphincter action does not affect the pancreaticobiliary junction, and pancreatic juice frequently refluxes into the biliary tract. Persistence of refluxed pancreatic juice injures epithelium of the biliary tract and promotes cancer development, resulting in higher rates of carcinogenesis in the biliary tract. In a nationwide survey, biliary cancer was detected in 21.6% of adult patients with congenital biliary dilatation (bile duct cancer, 32.1% vs. gallbladder cancer, 62.3%) and in 42.4% of PBM patients without biliary dilatation (bile duct cancer, 7.3% vs. gallbladder cancer, 88.1%). Pathophysiological conditions due to pancreatobiliary reflux occur in patients with high confluence of pancreaticobiliary ducts, a common channel ≥6 mm long, and occlusion of communication during contraction of the sphincter. Once the diagnosis of PBM is established, immediate prophylactic surgery is recommended. However, the surgical strategy for PBM without biliary dilatation remains controversial. To detect PBM without biliary dilatation early, MRCP is recommended for patients showing gallbladder wall thickening on screening US under suspicion of PBM.

    Full Text Available Cancer of unknown primary (CUP is the finding of a metastatic cancerous lesion without an established primary source localized within the body. CUP can be of any cancer cell type, however, adenocarcinoma is most often identified by histology. Up to 5% of all malignant diagnoses are classified as CUP. PET is an imaging modality often utilized to distinguish a primary source in the setting of CUP, yet often a primary is never identified. CUP can be further stratified using specific qualifiers as favorable and unfavorable, indicating the potential therapeutic response to treatment regimens. Treatment approach to CUP relies heavily on the cell type identified by histology, the location of the lesion, and the amount of spread within the body. In the typical setting and presentation, per current literature, CUP arises in the 7th decade of life in patients with multiple comorbidities, and often has a poor prognostic value. This case report identifies an atypical presentation of CUP, a 38-year-old Caucasian female with an axillary mobile mass, and no associated systemic symptoms. Biopsy of the node and immunohistochemical staining showed histology consistent with metastatic carcinoma. Mammography, MRI, and PET scan found no evidence of tumor primary or distant metastasis. Further staining confirmed metastatic carcinoma consistent with breast origin, without an established breast primary. As in this case, CUP may present in an atypical manner, warranting a thorough investigation aiming to identify the tumor primary to aid in identification of a proper treatment regimen and approach.

    Gallbladder carcinoma is the most common biliary tract tumor and the fifth most common gastrointestinal tract cancer .The prognosis of gallbladder carcinoma is poor and less than 5% of the patients are still alive five years postoperatively. Gallbladder specimens were obtained during surgical operations performed in eleven patients for resection of a gallbladder carcinoma, and during five autopsies (control cases selected among patients who died from for other causes, excluding those suffering from biliary or hepatic diseases). Immunohistochemical characterization and distribution of neurotrophins, with their respective receptors, were analyzed. The actual role played by these neurotrophic factors in the general regulation, vascular permeability, algic responsiveness, release of locally active substances and potential tumorigenesis in the gallbladder and biliary ducts compartment remains controversial. Our study revealed an increased immunohistochemical expression of NGF and TrKA in the epithelium and in the epithelial glands of the gallbladder carcinoma together with an evident immunoreactivity for BDNF in the same neoplastic areas. An evident immunoreactivity for NGF, TrKA and BDNF was observed in control specimens of gallbladder obtained during autopsies, whereas a weak or quite absent immunoreactivity was observed in the same specimens for NT4, TrKC and p75. On the contrary an appreciable immunoreactivity for p75 was observed in the specimens harvested from patients with gallbladder carcinoma. We also investigated the expression of some known tumor markers such as MIB-1 (anti Ki-67), CD34 and CA15-3, to identify a possible correlation between the expression of these molecular factors and the prognosis of gallbladder carcinoma. They resulted highly expressed in the stroma (CD34 and CA 15-3) and in the epithelium/epithelial glands (MIB-1) of the neoplastic areas and appeared to be almost absent in the control cases, suggesting that these markers, taken together

    Full Text Available Gallbladder carcinoma is the most common biliary tract tumor and the fifth most common gastrointestinal tract cancer .The prognosis of gallbladder carcinoma is poor and less than 5% of the patients are still alive five years postoperatively.1 Gallbladder specimens were obtained during surgical operations performed in eleven patients for resection of a gallbladder carcinoma, and during five autopsies (control cases selected among patients who died from for other causes, excluding those suffering from biliary or hepatic diseases. Immunohistochemical characterization and distribution of neurotrophins, with their respective receptors, were analyzed. The actual role played by these neurotrophic factors in the general regulation, vascular permeability, algic responsiveness, release of locally active substances and potential tumorigenesis in the gallbladder and biliary ducts compartment remains controversial. Our study revealed an increased immunohistochemical expression of NGF and TrKA in the epithelium and in the epithelial glands of the gallbladder carcinoma together with an evident immunoreactivity for BDNF in the same neoplastic areas. An evident immunoreactivity for NGF, TrKA and BDNF was observed in control specimens of gallbladder obtained during autopsies, whereas a weak or quite absent immunoreactivity was observed in the same specimens for NT4, TrKC and p75. On the contrary an appreciable immunoreactivity for p75 was observed in the specimens harvested from patients with gallbladder carcinoma. We also investigated the expression of some known tumor markers such as MIB-1 (anti Ki-67, CD34 and CA15-3, to identify a possible correlation between the expression of these molecular factors and the prognosis of gallbladder carcinoma. They resulted highly expressed in the stroma (CD34 and CA 15-3 and in the epithelium/epithelial glands (MIB-1 of the neoplastic areas and appeared to be almost absent in the control cases, suggesting that these markers

    Full Text Available Squamous cell ovarian and sigmoid colon carcinomas are extremely rare malignancies. Because of their rarity, it is difficult to investigate the clinical characteristics and prognosis of patients with theses malignancies, and therefore, the increased interest in each clinical case report is highly relevant. Multiple primary squamous cell ovarian and sigmoid colon carcinomas are the subject of discussion and differential diagnosis of sigmoid colon cancer with secondary ovarian cancer. Histopathological and clinical characteristics of the tumors were present and evidences in favor of the multiple primary malignancies were given. The association of squamous cell ovarian and sigmoid colon carcinomas with human papilloma virus type 16 was shown.

Evidence has shown that combination therapy of UDCA with bezafibrate significantly improved liver function. A meta-analysis was performed to assess the efficacy and safety of UDCA and bezafibrate combination therapy in the treatment of PBC.Results: Nine trials, with a total of 269 patients, were included in the analysis. The bias risk of these trials was high.

    Between January 1 1974 and October 31 1987, 98 patients with biopsy proven unresectable adenocarcinoma of the pancreas were treated with I-125 implants during laparotomy. Presenting symptoms were pain, jaundice, and weight loss. All patients underwent laparotomy and surgical staging. Thirty patients had T1NoMo disease, 47 patients had T2-3NoMo disease, and 21 patients had significant regional lymph node involvement (T1-3N1Mo). The surgical procedure performed was biopsy only (16 patients), gastric bypass, biliary bypass, and partial or total pancreatectomy with incomplete resection. The total activity and the number of seeds used were determined from the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram. Stereoshift localization X ray films were taken 3-6 days after operation. The mean activity, minimal peripheral dose (MPD), and volume of the implants were 35 mCi, 13,660 cGy, and 53 cm3, respectively. In addition, 27 patients received postoperative external irradiation and 27 patients received chemotherapy. Postoperative complications were observed in 19 patients. These included post-operative death (1 patient), biliary fistula (4), intraabdominal abscess (4), GI bleeding (3), gastric or small bowel obstruction (6), sepsis (5), and deep vein thrombophlebitis (4). Pain relief was obtained in 37/57 patients (65%) presenting with pain. A multivariate analysis showed that four factors significantly affected survival: T stage, N stage, administration of chemotherapy, and more than 30% reduction in the size of the implant on follow-up films. The median survival for the entire group was 7 months. A subgroup of patients with T1No stage disease who received chemotherapy survived 18.5 months. The indications for I-125 seed implantation in unresectable carcinoma of the pancreas are discussed.

    Postoperative benign biliary stricture in the anastomotic site is one of the most common complications of biliary-enteric anastomosis, with a rate of 6.87% after 2-13 years of follow-up. If untreated, biliary strictures can induce other complications such as recurrent cholangitis, intrahepatic stones, pancreatitis and secondary biliary cirrhosis. We report our experience with extracorporeal shock wave lithotripsy (ESWL) in a patient with a massive symptomatic stone proximal to an anastomotic biliary stricture.

    Primary vaginal carcinoma is a rare malignancy. There is little information regarding the optimal treatment. Management has primarily been with external-beam radiation therapy and brachytherapy. This paper examines the importance of brachytherapy and the significance of its techniques in the treatment of this disease. Brachytherapy plays an important part in the management of primary vaginal carcinoma. External-beam radiation therapy alone is not an adequate treatment for this disease. For stages II and III disease, there is a trend toward improved disease-free survival with the use of a temporary interstitial implant compared to an intracavitary application

    Full Text Available We report a unique case of combined primary neuroendocrine carcinoma (NEC and hepatocellular carcinoma (HCC of the liver in a 65-year-old male patient. The patient underwent segmental resection of the liver and regional lymph node dissection for a tumor mass that measured 7.5 cm in diameter in the right lobe, with regional lymphadenopathy. Histologically, the hepatic tumor was composed of predominantly small-cell NEC, but admixed with a small island of moderately differentiated HCC. We speculate that the NEC originated from a poorly differentiated tumor clone of an HCC that underwent neuroendocrine differentiation, and that this tumor was now at the end stage of the transitional period from HCC to NEC, based on the small amount of disappearing HCC. Ki-67 and p53 expression were higher in the NEC than in the HCC, and the lymph nodes showed only metastatic NEC. Therefore, this kind of tumor had a more aggressive clinical course in accordance with being an NEC rather than a conventional HCC. Three months after operation, the patient had multiple recurrent tumor nodules within the liver, spreading the metastasis to the adrenal glands and para-aortic lymph nodes. The patient died 1 year after operation.

    Full Text Available Abstract Background The incidence of multiple primary malignant neoplasms increases with age and they are encountered more frequently nowadays than before, the phenomenon is still considered to be rare. Case presentation We report a case of a man in whom urinary bladder transitional cell carcinoma, metachronous prostate adenocarcinoma and small cell lung carcinoma were diagnosed within an eighteen-month period. The only known predisposing factor was that he was heavy smoker (90–100 packets per year. The literature on the phenomenon of multiple primary malignancies in a single patient is reviewed and the data is summarized. Conclusion It is important for the clinicians to keep in mind the possibility of a metachronous (successive or a synchronous (simultaneous malignancy in a cancer patient. It is worthy mentioning this case because clustering of three primary malignancies (synchronous and metachronous is of rare occurrence in a single patient, and, to our knowledge, this is the first report this combination of three carcinomas appearing in the same patient.

    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

    Mesenchymal origin of ureter tumors account for less than 3 percent of all primary ureteral tumors. Among mesenchymal tumors, primary leiomyoma of ureter is extremely rare. Here, we present a case of primary leiomyoma of ureter coexisting with renal cell carcinoma. When encountering well-defined homogeneously enhanced mass of ureter on computed tomography, radiologist should keep in mind that ureteral leiomyoma should be considered as differential diagnosis.

    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.

    To evaluate magnetic resonance imaging (MRI) findings in patients with primary biliary cirrhosis (PBC) and to determine the value of diffusion-weighted imaging (DWI) in the assessment of liver fibrosis. The following MRI findings were reviewed in 44 patients: periportal T2-weighted hyperintensity, periportal halo sign (T1- and T2-weighted periportal hypointensity), lymphadenopathy, signs of portal hypertension and morphological liver changes. Apparent diffusion coefficient (ADC) was calculated for six locations in the liver for b = 800 s/mm 2 . Periportal hyperintensity and periportal halo sign were observed in 72.7% and 66.7% of patients, respectively. Lymphadenopathy was noted in 28 patients (63.6%) and diffuse hepatomegaly in 18 (40.9%). Significant positive correlation was observed between histological stage and periportal halo sign (p = 0.613), hepatomegaly (p = 0.443), and portosystemic collaterals (p = 0.391). The mean ADCs (x 10 -3 mm 2 /s) were significantly different at stage I versus III and IV, and stage II versus IV. No significant difference was found between stages II and III. For prediction of stage ≥ II and stage ≥ III areas under receiver operating characteristic curves were 0.879 and 0.906, respectively. MRI with DWI could be used as a part of diagnostic protocol in the further evaluation of PBC patients providing noninvasive assessment of liver fibrosis progression. (orig.)

    The goal of this study was to evaluate the anti-tumour activity and toxicoses of vinorelbine as a palliative rescue therapy for dogs with primary urinary bladder carcinoma. Thirteen dogs refractory to prior chemotherapeutics and one dog naïve to chemotherapeutic treatment were enrolled. Vinorelbine (15 mg m(-2) IV) was administered intravenously along with concurrent oral anti-inflammatory drugs, if tolerated. A median of six doses of vinorelbine (range: 1-16) was administered. Two dogs (14%) had partial responses, and eight (57%) experienced stable disease. Subjective improvement in clinical signs was noted in 11 dogs (78%). Adverse events were mild and primarily haematological in nature. Median time to progression was 93 days (range: 20-239 days). Median survival time for all dogs was 187 days; median survival for 13 pre-treated dogs was 207 days. Vinorelbine may have utility in the management of canine primary urinary bladder carcinoma and should be evaluated in a prospective study. © 2013 John Wiley & Sons Ltd.

    Percutaneous transhepatic biliary drainage was successfully made 20 times on 17 patients of obstructive jaundice for recent 1 year since June 1981 at Department of Radiology in Seoul National University Hospital. The causes of obstructive jaundice was CBD Ca in 13 cases, metastasis in 2 cases, pancreatic cancer in 1 case and CBD stone in 1 case. Percutaneous transhepatic biliary drainage is a relatively ease, safe and effective method which can be done after PTC by radiologist. It is expected that percutaneous transhepatic biliary drainage should be done as an essential procedure for transient permanent palliation of obstructive jaundice

    2012-02-01

    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.

    A rat monoclonal antibody, YPC2/38.8, was selected from a panel of antibodies derived by immunising rats with fresh human colorectal carcinoma. It was found to bind to a 30,000 dalton protein present on the cell surface of normal colon and liver. This protein was increased 10-fold on primary hepatocellular carcinoma (PHC) cells. After labelling with /sup 131/I, YPC2/38.8 was shown to localise human PHCs grown as xenografts in immunosuppressed mice. The authors conclude that YPC2/38.8 may have potential for diagnostic localisation and possibly thence for the selective targeting of drugs or toxins in patients with PHC arising in a liver unaffected by significant parenchymal disease. 16 refs.; 4 figs.; 1 table.

    A 62-year-old man with a 20-year history of chronic ulcerative colitis and a 9-year history of primary sclerosing cholangitis (PSC) underwent orthotopic liver transplantation because of symptoms related to PSC and cholangiographic features compatible with a biliary neoplasm. Study of the excised liver revealed papillary mucosal lesions in the common hepatic duct and the right and left hepatic ducts as well as cholangiectases and other features typically associated with PSC. The papillary lesions consisted of abundant fibrovascular stroma covered by biliary epithelium with low-grade and high-grade dysplasia. Some periductal glands were also dysplastic. These features distinguished papillary dysplasia from classic biliary papillomatosis. Only one focus of microinvasion was found; there were no metastases. Among 60 cases of PSC in whom the entire liver could be studied after orthotopic liver transplantation, this was the only instance of unequivocal dysplasia. However, in one specimen, papillary hyperplasia was found. Detailed macroscopic and microscopic rereview of 23 livers from our patients with the longest history of PSC (range, 5-24 years) failed to reveal any additional cases with dysplasia. It is concluded that (a) papillary mucosal lesions in PSC may represent papillary dysplasia without invasion; (b) these lesions may evolve from papillary hyperplasia; (c) the process may be largely, if not entirely, in situ; and (d) the prevalence of dysplasia and carcinoma of bile ducts may be less than the 7%-9% reported in the literature for malignancies associated with PSC.

    To evaluate the effect of temporary stent graft placement in the treatment of benign anastomotic biliary strictures. Nine patients, five women and four men, 22-64 years old (mean, 47.5 years), with chronic benign biliary anastomotic strictures, refractory to repeated balloon dilations, were treated by prolonged, temporary placement of stent-grafts. Four patients had strictures following a liver transplantation; three of them in bilio-enteric anastomoses and one in a choledocho-choledochostomy. Four of the other five patients had strictures at bilio-enteric anastomoses, which developed after complications following laparoscopic cholecystectomies and in one after a Whipple procedure for duodenal carcinoma. In eight patients, balloon-expandable stent-grafts were placed and one patient was treated by insertion of a self-expanding stent-graft. In the transplant group, treatment of patients with bilio-enteric anastomoses was unsuccessful (mean stent duration, 30 days). The patient treated for stenosis in the choledocho-choledochostomy responded well to consecutive self-expanding stent-graft placement (total placement duration, 112 days). All patients with bilio-enteric anastomoses in the non-transplant group were treated successfully with stent-grafts (mean placement duration, 37 days). Treatment of benign biliary strictures with temporary placement of stent-grafts has a positive effect, but is less successful in patients with strictures developed following a liver transplant.

Nine patients, five women and four men, 22-64 years old (mean, 47.5 years), with chronic benign biliary anastomotic strictures, refractory to repeated balloon dilations, were treated by prolonged, temporary placement of stent-grafts. Four patients had strictures following a liver transplantation; three of them in bilio-enteric anastomoses and one in a choledocho-choledochostomy. Four of the other five patients had strictures at bilio-enteric anastomoses, which developed after complications following laparoscopic cholecystectomies and in one after a Whipple procedure for duodenal carcinoma. In eight patients, balloon-expandable stent-grafts were placed and one patient was treated by insertion of a self-expanding stent-graft. In the transplant group, treatment of patients with bilio-enteric anastomoses was unsuccessful (mean stent duration, 30 days). The patient treated for stenosis in the choledocho-choledochostomy responded well to consecutive self-expanding stent-graft placement (total placement duration, 112 days). All patients with bilio-enteric anastomoses in the non-transplant group were treated successfully with stent-grafts (mean placement duration, 37 days). Treatment of benign biliary strictures with temporary placement of stent-grafts has a positive effect, but is less successful in patients with strictures developed following a liver transplant.

    Primary biliary cirrhosis (PBC) is an immune-mediated chronic cholestatic liver disease, characterized by increased concentrations of serum IgM and the presence of circulating anti-mitochondrial antibodies. Although bone diseases such as osteoporosis or osteodystrophy are commonly associated with PBC, osteomalacia which is caused by abnormal vitamin D metabolism, mineralization defects, and phosphate deficiency has not been recognized as a complication of PBC. We report the case of a 49-year-old Japanese woman who complained of multiple fractures. Hypophosphatemic osteomalacia was diagnosed from a low serum phosphorus level, 1,25-dihydroxyvitamin D3 level, high levels of bone specific alkaline phosphatase and the findings of bone scintigraphy, although a bone biopsy was not performed. Twenty four hour urine demonstrated a low renal fractional tubular reabsorption of phosphate, increased fractional excretion of uric acid and generalized aminoaciduria. An intravenous bicarbonate loading test suggested the presence of proximal renal tubular acidosis (RTA). These biochemical data indicated Fanconi syndrome with proximal RTA. A kidney biopsy demonstrated the features of tubulointerstitial nephritis (TIN). The patient was also suspected as having primary biliary cirrhosis (PBC) because of high levels of alkaline phosphatase, IgM and the presence of anti-mitochondrial M2 antibody, though biochemical liver function was normal. Sequential liver biopsy was compatible with PBC and the diagnosis of PBC was definite. After administration of 1,25 dihydroxyvitamin D3, neutral potassium phosphate, sodium bicarbonate for osteomalacia and subsequent predonizolone for TIN, symptoms of fractures were relieved and renal function including Fanconi syndrome was ameliorated. In this case, asymptomatic PBC was shown to induce TIN with Fanconi syndrome with dysregulation of electrolytes and vitamin D metabolism, which in turn led to osteomalacia with multiple fractures. Osteomalacia has not

    Full text: Percutaneous transhepatic cholangiography (PTC) is an X-ray or US guided procedure that involves the injection of a contrast material directly into the bile ducts inside the liver to produce pictures of them. If a blockage or narrowing is found, additional procedures may be performed: 1. insertion of a catheter to drain excess bile out of the body or both - internal and external; 2. plastic endoprothesis placement; 3. self-expandable metal stents placement to help open bile ducts or to bypass an obstruction and allow fluids to drain. Current percutaneous biliary interventions include percutaneous transhepatic cholangiography (PTC) and biliary drainage to manage benign and malignant obstructions. Internal biliary stents are either plastic or metallic, and various types of each kind are available. Internal biliary stents have several advantages. An external tube can be uncomfortable and have a psychological disadvantage. An internal stent prevents the problems related to external catheters, for example, pericatheter leakage of bile and the need for daily flushing. The disadvantages include having to perform endoscopic retrograde cholangiopancreatography (ERCP) or new PTC procedures to obtain access in case of stent obstruction. Better patency rates are reported with metallic than with plastic stents in cases of malignant obstruction, though no effect on survival is noted. Plastic internal stents are the cheapest but reportedly prone to migration. Metallic stents are generally not used in the treatment of benign disease because studies have shown poor long-term patency rates. Limited applications may include the treatment of patients who are poor surgical candidates or of those in whom surgical treatment fails. Most postoperative strictures are treated surgically, though endoscopic and (less commonly) percutaneous placement of nonmetallic stents has increasingly been used in the past few years. Now there are some reports about use of biodegradable biliary

    Objective: To investigate the effect of cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma. Methods: 124 cases with primary liver carcinoma were randomly divided into two groups: 60 cases were treated by TACE and cryotherapy; the other 64 cases were simply done by TACE as control. In general, TACE was undertaken once a month and altogether three times for a course. Cryotherapy was undergone 1-3 times for a course. Results: The total effective rates (CR + PR) were 45.3% for the control group and 68.3% for the combined therapy group, with an obvious difference between the two groups, 0.5, 1, 1.5 years survival rate were 81.3%, 62.5%, 43.8% respectively in the control group; 93.3%, 83.3%, 63.3% respectively for the combined group. There was an obvious difference between the two groups of 1, 1.5 years of survival rates. Conclusions: Cryotherapy of employing Argon/Helium assisted with TACE for the unresectable primary liver carcinoma is feasible with raising the effective rate and prolonging survival time. (authors)

    Full Text Available Abstract Primary mesenchymal chondrosarcoma of the kidney is rare, and it shows distinct undifferentiated tumor cells and well differentiated cartilagenous components. Also assident infiltrating urothelial carcinoma of the ureter is an extremely rare cancer. We report a case of primary mesenchymal chondrosarcoma occurring in the left kidney with an ipsilateral and distinct distal ureteric implant, and a coexisting infiltrating urothelial carcinoma of the ureter in a 64-year-old man. Histopathological examination and immunohistochemical studuies showed the classic features of mesenchymal chondrosarcoma in kidney, as well as a few infiltrating urothelial in ureter. Multitarget fluorescence in situ hybridization (FISH suggested that the development of the urothelial carcinoma in the ureter may be triggered or induced by the chondrosarcoma component. The patient died 2 month after left nephro-ureterectomy. This is the first reported case of a primary mesenchymal chondrosarcoma of the kidney with coexisting infiltrating urothelial carcinoma of the ureter.

    2014-01-01

    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.

    This study aims to compare the clinical outcomes and costs between percutaneous transhepatic biliary stenting (PTBS) and surgical bypass. We randomly assigned 142 patients with unresectable malignant biliary obstruction between 2005 and 2010 to receive PTBS or surgical bypass as palliative treatment. PTBS was successfully performed in 70 patients who formed the PTBS group (failed in 7 patients). Sixty five patients underwent surgical bypass treatment. Additional gastrojejunostomy was performed in five patients. The effectiveness of biliary drainage, hospital stay, complications, cost, survival time and mortality were compared. Patients in PTBS group had shorter hospital stay and lower initial and overall expense than the surgical group (pPTBS group was significantly lower than surgical group (3/75 vs. 11/65, p=0.0342). Late complication in PTBS group did not differ significantly from surgical group (9/70 vs. 6/65, p=0.6823). The survival curves in the two groups showed no significant difference (p=0.1032). PTBD is a better palliative treatment than surgical bypass for unresectable malignant biliary obstruction for its high effectiveness of biliary drainage and acceptable expense and complication.

It accounts for less than 1% of all urinary bladder carcinomas. The purpose of this study is to review the clinical features, the treatment modalities, and the overall survival of these patients. We also compare the clinical outcomes between patients of bladder small cell carcinoma (SCC and bladder urothelial carcinoma (UC. Materials and methods: We reviewed the charts of patients with bladder tumors from January 1995 to December 2012 in the Chang Gung Memorial Hospital. A total of 2421 malignant bladder tumor patients were reviewed and there were 18 patients who were diagnosed with primary bladder SCC. The patients' characteristics, including age, gender, smoking history, presented symptoms, tumor size, locations, clinical stages, treatment modalities, pathology appearance, recurrence conditions, and survival conditions were all recorded. We also compared the clinical outcomes and the overall survival rates between patients with bladder SCC and those with UC. Results: Bladder SCC accounted for about 0.74% of all bladder malignancies in our institution. The mean age at diagnosis was 70.67 years, and the male-to-female ratio was 2.6:1. Thirteen patients had a history of cigarette smoking. All patients presented with symptoms of gross hematuria, and three of them had bladder tamponade requiring blood clot evacuation by cystoscopy. Only one patient had T1 disease, ten patients had stage III disease, and seven patients had lymph node or distant metastasis (stage IV disease. The mean tumor size was 4.29 cm in diameter. For the majority (61.11% of patients, SCC coexisted with UC components. The average survival time

EUS-guided hepaticogastrostomy, coledochoduodenostomy and choledoantrostomy are advanced biliary and pancreatic endoscopy procedures, and together make up the echo-guided biliary drainage. Hepaticogastrostomy is indicated in cases of hilar obstruction, while the procedure of choice is the coledochoduodenostomy or choledochoantrostomy in distal lesions. Both procedures must be performed only after unsuccessful ERCPs. The indication of these procedures must be made under a multidisciplinary view while sharing information with the patient or legal guardian. Hepaticogastrostomy and coledochoduodenostomy or choledochoantrostomy are feasible when performed by endoscopists with expertise in biliopancreatic endoscopy. Advanced echo-endoscopy should currently be performed under a rigorous protocol in educational institutions.

    The aim of this study was to assess short- and long-term outcomes of malignant biliary obstruction (MBO) treatment by percutaneous transhepatic biliary stenting (PTBS) with uncovered selfexpandable metallic stents (SEMS), and to identify predictors of survival. A nine-year, single-centre study from a prospectively collected database included 222 patients with inoperable MBO treated by PTBS with uncovered nitinol SEMS. Technical and clinical success rates were 95.9% and 82.4%, respectively. The total rate of postprocedural complications was 14.4%. The mean durations of the primary and secondary stent patency were 114.7±15.1 and 146.4±21.2 days, respectively. The 30-day mortality rate was 15.3% with no procedure-related deaths. The mean estimated length of survival was 143.3±20.6 days. Independent predictors increasing the risk of death included higher than 115 μmol/L serum bilirubin 2-5 days after biliary stenting (HR 3.274, P =0.019), distal (non-hilar) obstruction of the bile ducts (HR 3.711, P =0.008), Bismuth-Corlette type IV stricture (HR 2.082, P =0.008), obstruction due to gallbladder cancer (HR 31.029, P =0.012) and only partial drainage of liver parenchyma (HR 4.158, P =0.040). PTBS with uncovered SEMS is an effective and safe method for palliative treatment of MBO. Serum bilirubin higher than 115 μmol/L 2-5 days after the procedure has a significant negative impact on patients' survival. Lower survival is also determined by distal bile duct obstruction, Bismuth- Corlette type IV stricture, biliary obstruction caused by gallbladder cancer and when only partial liver drainage is applied.

    Primary fallopian tube carcinoma (PFTC) is a rare tumour of the female genital tract with an incidence of 0.1-1.8% of all genital malignancies, and it is very difficult to diagnose preoperatively, because of its non-specific symptomatology. In most cases, it is an intraoperative finding or a histopathological diagnosis. It is a tumour that histologically and clinically resembles epithelial ovarian cancer. We are reporting a case of a 62-year-old, postmenopausal women with primary fallopian tube carcinoma of the right fallopian tube in stage IA. The patient has lower abdominal pain, watery vaginal discharge and repeated episodes of bleeding from the vagina. The clinical and radiological findings suggested a right adnexal tumour with elevated CA-125 levels. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy and peritoneal washing were performed. Pathologic confirmation of primary serous cystadenocarcinoma of the right fallopian tube was made. Peritoneal washings were negative for malignancy. FIGO stage was considered as IA, and the patient received no courses of chemotherapy and postoperative radiation because she refused it. Ten months after initial surgery, the patient is alive and in good condition. Cytoreduction surgery followed by adequate cycles of chemotherapy is an important strategy to improve patients' prognosis.

    Full Text Available Hydatic cyst is an illness that appears in consequence of the cystic form of small strap-shaped worm Echinococcus granulosis. Frequently, cysts exist in the lungs and liver. Peritoneal involvement is rare, and generally occurs as a result of second inoculation from rupture of a liver-located hydatic cyst. Primary ovarian hydatic cyst is very rare. A 56-year-old female patient was admitted to Emergency Service with the complaint of stomachache and swollen abdomen. From ultrasonographic examination, a right ovarian 52 × 45-mm heterogeneous semi-solid cystic mass and right hydronephrosis were detected. As a result of the tomographic examination, the right ovarian growth was judged to be a 60 × 45-mm lobule contoured, septal, heterogeneously cystic mass (ovarian carcinoma. Depending on these indicators and with the diagnosis of ovarian carcinoma, laparotomy was planned. During the observation, a mass that compressed on the right ureter and dilatation in the right ureter were determined. The mass was approximately 6 cm long and smoothly contoured, including widespread adhesions, and also obliteration of the pouch of Douglas. The mass was excised and total abdominal hysterectomy and bilateral salpingo-oopherectomy performed. After a pathological examination, hydatid cyst was diagnosed. Although pointing at the issue of the distinctive diagnosis of pelvic and peritoneal mass, it should be realized that the existence of primary peritoneal and pelvic involvement of the hydatic cyst is generally a result of the second inoculation, and is also more common in regions in which Echinococcus granulosa is endemic and livestock production is prevalent.

    Several studies showed that gain-of-function somatic mutations affecting the catalytic domain of EGFR in non-small cell lung carcinomas were associated with response to gefitinib and erlotinib, both EGFR-tyrosine kinase inhibitors. In addition, 4% of non-small cell lung carcinomas were shown to have ERBB2 mutations in the kinase domain. In our study, we sought to determine if similar respective gain-of-function EGFR and ERBB2 mutations were present in hepatoma and/or biliary cancers. We extracted genomic DNA from 40 hepatoma (18) and biliary cancers (22) samples, and 44 adenocarcinomas of the lung, this latter as a positive control for mutation detection. We subjected those samples to PCR-based semi-automated double stranded nucleotide sequencing targeting exons 18–21 of EGFR and ERBB2. All samples were tested against matched normal DNA. We found 11% of hepatoma, but no biliary cancers, harbored a novel ERBB2 H878Y mutation in the activating domain. These newly described mutations may play a role in predicting response to EGFR-targeted therapy in hepatoma and their role should be explored in prospective studies

    Full Text Available We report a 44-year-old man with primary gastric small cell carcinoma who showed a remarkable response to chemotherapy specific for pulmonary small cell carcinoma. The patient had been admitted to another local hospital because of intermittent epigastralgia. An upper gastrointestinal examination there revealed an ulcerative tumor, 5 cm in diameter, on the lesser curvature side of the cardia, and endoscopic biopsy reported adenocarcinoma. Computed tomography revealed a mass over the lesser curvature of the stomach and some enlarged regional lymph nodes. Radical total gastrectomy, lymph node dissection, Roux-en-Y esophagojejunostomy and splenectomy were performed at our hospital. Pathology revealed gastric mucosa infiltrated by small-sized tumor cells with scanty cytoplasm and hyperchromatic nuclei. Immunohisto- chemically, the tumor cells were positive for synaptophysin, chromogranin A, and CD56. Primary gastric small cell carcinoma was diagnosed. The postoperative course, complicated by shock due to bleeding, wound infection and intra-abdominal abscess, took more than 2 months to resolve. Follow-up computed tomography showed tumor recurrence with multiple enlarged lymph nodes in the aortocaval region and hepatic hilum. The patient received palliative chemotherapy consisting of cisplatin 80 mg/m2 on day 1 and etoposide 80 mg/m2 on days 1–3 every 28 days, and had partial response to the chemotherapy, with a progression-free survival of 10 months. Chemotherapy with cisplatin and etoposide used for small cell carcinoma of the lung is a good treatment for gastric small cell carcinoma.

    Full Text Available Abstract Background Extramedullary plasmacytomas are seldom solitary and usually progress to diffuse myelomatosis. Plasmacytomas of the breast are rare, especially when not associated multiple myeloma. Synchronous infiltrating ductal carcinoma and primary extramedullary plasmacytoma of the breast have not previously reported. Case presentation A 27-years-old woman with an untreated upper outer quadrant breast mass for 1-year was referred to our cancer hospital for surgical evaluation of increasing breast pain. Postoperatively, microscopic examination revealed an infiltrating ductal carcinoma complicated by an extramedullary plasmacytoma divided by fibrous tissue in one section. Following surgery, the patient received chemotherapy for the carcinoma and radiotherapy for the plasmacytoma. Conclusion In this case, careful histopathology examination was essential to make the correct diagnosis and therapy for these synchronous lesions. The patient finished chemotherapy and radiotherapy without significant adverse effects.

    Penetrating or blunt injury to the biliary tree remains a rare complication of trauma occurring in 0.1% of trauma admissions. Because of the different presentations, sites of biliary tract injury, and associated organ injury, there are many possible management pathways to be considered. A retrospective analysis of prospectively gathered data was performed for all gallbladder and biliary tract injuries presenting to the trauma service or hepatobiliary unit of the Royal Melbourne Hospital between January 1, 1999, and March 30, 2011. There were 33 biliary injuries in 30 patients (0.1%) among 26,014 trauma admissions. Three of the 30 patients (10%) died. Of 10 gallbladder injuries, 8 were managed with cholecystectomy. There were 23 injuries to the biliary tree. Fourteen patients had injuries to the intrahepatic biliary tree of which seven involved segmental ducts. Of these, four segmental duct injuries required hepatic resection or debridement. Nine patients had injury to the extrahepatic biliary tree of which five required T-tube placement ± bilioenteric anastomosis and one a pancreaticoduodenectomy. Biliary injury is a rare but important consequence of abdominal trauma, and good outcomes are possible when a major trauma center and hepatopancreaticobiliary service coexist. Cholecystectomy remains the gold standard for gallbladder injury. Drainage with or without endoscopic stenting will resolve the majority of intrahepatic and partial biliary injuries. Hepaticojejunostomy remains the gold standard for complete extrahepatic biliary disruption. Hepatic and pancreatic resection are only required in the circumstances of unreconstructable biliary injury. Therapeutic study, level V. Copyright © 2012 by Lippincott Williams & Wilkins.

    The purpose was to retrospectively compare two-dimensional (2D) magnetic resonance cholangiography (MRC) including breath-hold single-shot rapid acquisition with relaxation enhancement (RARE) and multislice half-Fourier RARE versus navigator-triggered 3D-RARE MRC in the evaluation of biliary malignancy. MRC findings were evaluated in 31 patients with malignant biliary obstruction, including biliary malignancy, gallbladder carcinoma, and ampullary cancer. Two observers independently reviewed the images to assess the overall image quality, artifacts, ductal conspicuity, extent of disease, diagnostic confidence of tumor extent, and origin of tumor. The results were compared with surgical and histopathologic findings. Studies obtained with 3D-MRC were of significantly higher technical quality than those obtained with 2D-MRC. However, the accuracy between two sequences for classification of tumor showed no statistical significance. There was no significant difference between the Az values of 2D- and 3D-MRC for overall tumor extent in bilateral second order branch, intrapancreatic common bile duct (CBD) involvement (Az = 0.889, 0.881 for 2D and Az = 0.903, 0.864 for 3D). Nor was there a significant difference between two sequences in the assessment of the origin of tumor. Although 3D-MRC has superior image quality over 2D-MRC, 3D-MRC showed no statistically significant difference in accuracy compared with 2D-MRC for evaluating the extent of disease in malignant biliary obstructions.

    It is difficult to carry out meta-analyses or to compare the results of different studies of biliary stents because there is no uniform evaluation method. Therefore, a standardized reporting system is required. We propose a new standardized system for reporting on biliary stents, the 'TOKYO criteria 2014', based on a consensus among Japanese pancreatobiliary endoscopists. Instead of stent occlusion, we use recurrent biliary obstruction, which includes occlusion and migration. The time to recurrent biliary obstruction was estimated using Kaplan-Meier analysis with the log-rank test. We can evaluate both plastic and self-expandable metallic stents (uncovered and covered). We also propose specification of the cause of recurrent biliary obstruction, identification of complications other than recurrent biliary obstruction, indication of severity, measures of technical and clinical success, and a standard for clinical care. Most importantly, the TOKYO criteria 2014 allow comparison of biliary stent quality across studies. Because blocked stents can be drained not only using transpapillary techniques but also by an endoscopic ultrasonography-guided transmural procedure, we should devise an evaluation method that includes transmural stenting in the near future. © 2014 The Authors.

    Full Text Available Late recurrent primary biliary cirrhosis (PBC following orthotopic liver transplant remains a controversial topic. The first documented case of recurrence occurring in 16 patients transplanted for PBC and followed at the authors' institution for longer than one year is presented. A 54-year-old man transplanted for PBC developed a cholestatic pattern of enzyme elevation on post-transplant day (PTD 1305. Repeat antimitochondrial antibody was strongly positive (1:300 to 1:400. A liver biopsy revealed severe bile duct damage, lymphocytic cholangitis, focal periductal noncaseating granuloma and minimal endotheliitis. Recurrent PBC was diagnosed. At the time of orthotopic liver transplant this patient received induction immunosuppression with OKT3 crossed over to cyclosporine (CsA, azathioprine (AZA and prednisone. AZA was discontinued early and maintenance CsA tapered to a target trough level of 150 to 200 ng/mL by PTD 365. Prednisone was withdrawn by PTD 664. CsA levels during PTDs 1225 to 1305 (before elevation of hepatobiliary enzymes were below target at 114 to 166 ng/mL. Of the 16 patients, all but three were maintained on CsA, AZA and prednisone. One was on CsA (trough levels on target and AZA; the other two, including the patient with recurrent PBC, were on CsA only. The trough CsA level of the patient without recurrent PBC has been within the target range. The authors speculate that the underlying defect in immunoregulation in PBC persists post-transplant and that in the patient without recurrent PBC this defect was unmasked by lowered maintenance immunosuppression - allowing recurrence of PBC in a previously stable liver allograft.

    Biliary atresia is a severe and progressive inflammatory process of unknown cause, which initially involves the extrahepatic bile ducts but which quickly proceeds towards the intrahepatic bile tree leading rapidly to biliary cirrhosis. Biliary atresia is the major reason for liver transplantation during childhood. The extrahepatic bile ducts in biliary atresia become connective fibrotic cords which is irreversibly damaged.

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

    The carcinoma of unknown primary occupied 5 - 10 % of all malignancies. It is heterogenous in origin and has poor prognosis. The indentification of primary site and definition of involved area are more helpful in the management. The efficacy of positron emission tomography (PET) with fluorine-18- fluorodeoxyglucose (F18-FDG) positron emission tomography (PET) with fluorine-18-fluorodeoxyglucose (F18-FDG) was evaluated in several tumors such as breast, pancreas and head and neck cancers. In carcinoma of unknown primary, it was reported that the concentration of FDG was increased in tumor tissues, and that PET with F18-FDG may be much helpful in identifying primary site and defining involved area. The authors evaluated the usefulness of PET with F18-FDG in initial work-up and in evaluation after radical therapy for the patients with carcinoma of unknown primary. The visual analysis of FDG-PET would be helpful in identifying primary site and defining involved area. In detecting recurrent of residual lesions, FDG-PET seemed to be less helpful than conventional diagnostic work-up. But more studies with larger number of cases and longer follow-up were required. The results of this study can be bases for the direction of future studies for the usefulness of PET in carcinoma of unknown primary.

    CDC73 mutations frequently underlie the hyperparathyroidism-jaw tumor syndrome, familial isolated hyperparathyroidism (FIHP), and parathyroid carcinoma. It has also been suggested that CDC73 deletion analysis should be performed in those patients without CDC73 mutations. To investigate for CDC73 deletion in a family with FIHP previously reported not to have CDC73 mutations. Eleven members (six affected with primary hyperparathyroidism and five unaffected) were ascertained from the family, and multiplex ligation-dependent probe amplification was performed to detect CDC73 deletion using leukocyte DNA. A previously unreported deletion of CDC73 involving exons 1-10 was detected in five affected members and two unaffected members who were 26 and 39 years of age. Two affected members had parathyroid carcinomas at the ages of 18 and 32 years, and they had Ki-67 proliferation indices of 5 and 14.5% and did not express parafibromin, encoded by CDC73. Primary hyperparathyroidism in the other affected members was due to adenomas and atypical adenomas, and none had jaw tumors. Two affected members had thoracic aortic aneurysms, which in one member occurred with parathyroid carcinoma and renal cysts. A previously unreported intragenic deletion of exons 1 to 10 of CDC73 was detected in a three-generation family with FIHP, due to adenomas, atypical adenomas, and parathyroid carcinomas. In addition, two affected males had thoracic aortic aneurysms, which may represent another associated clinical feature of this disorder.

    Clear cell carcinoma (CCC) is a rare low-grade carcinoma that represents only 1% to 2% of all salivary glands tumors. The finding of a clear cell tumor in a parotid gland involves the necessity of differential diagnosis between primary clear cell parotid tumors and metastases, mainly from kidney. The biological behavior is not very aggressive and development, which is very slow, is usually asymptomatic and indeed, the tumor often reaches considerable dimensions before being diagnosed. The treatment of choice is the surgical excision. There are rare cases of local recurrence and distant metastases. The aim of this article is to report a primary CCC in the parotid gland that microscopically closely resembled a metastatic CCC of renal origin, making microscopic differentiation difficult.

    Full Text Available We herein report a rare case of squamous cell carcinoma of the hilar bile duct. A 66-year-old Japanese male patient was admitted to our hospital because of appetite loss and jaundice. Abdominal computed tomography revealed an enhanced mass measuring 10 × 30 mm in the hilar bile duct region. After undergoing biliary drainage, the patient underwent extended right hepatic lobectomy with regional lymph nodes dissection. The tumor had invaded the right portal vein. Therefore, we also performed resection and reconstruction of the portal vein. Histopathologically, the carcinoma cells exhibited a solid structure with differentiation to squamous cell carcinoma with keratinization and intercellular bridges. Immunohistochemical staining of the tumor cells revealed positive cytokeratin staining and negative CAM 5.2 staining. Based on these findings, a definitive diagnosis of well-differentiated squamous cell carcinoma of the hilar bile duct was made.

    Multiple genome-wide association studies of primary biliary cirrhosis (PBC) in both European and Japanese ancestries have shown significant associations of many genetic loci contributing to the susceptibility to PBC. Major differences in susceptibility loci between these two population groups were observed. In this study, we examined whether the most significant loci observed in either European and/or Japanese cohorts are associated with PBC in a Han Chinese population. In 1070 PBC patients and 1198 controls, we observed highly significant associations at CD80 (rs2293370, P = 2.67 × 10(-8)) and TNFSF15 (rs4979462, P = 3.86 × 10(-8)) and significant associations at 17q12-21 (rs9303277), PDGFB (rs715505), NF-κB1 (rs7665090), IL12RB2 (rs11209050), and STAT4 (rs7574865; all corrected P values rs7574865) was strongly associated after additional control samples were analyzed. Our study is the first large-scale genetic analysis in a Han Chinese PBC cohort. These results do not only reflect that Han Chinese PBC patients share common genetic susceptibility genes with both their Japanese and European counterparts but also suggest a distinctly different genetic susceptibility profile.

    Primary squamous cell carcinoma of the breast is a very rare tumor accounting for less than 0.4% of all breast cancers. Fewer than 100 cases have been reported in the literature so far. The diagnosis requires strict pathologic criteria to be fulfilled. Due to the rarity of this tumor the optimal treatment and prognosis are both unclear. Breast abscess as the initial presentation of a primary squamous cell breast carcinoma is an extremely rare clinical entity. In this study, we describe a case of a 61-year-old postmenopausal woman who presented with typical manifestations of a breast abscess and was diagnosed with a pure primary squamous cell breast carcinoma. Diagnostic evaluation and management of the patient are discussed along with a review of the literature. Despite its rarity, the possibility of a primary pure squamous cell breast carcinoma should always be considered in the differential diagnosis in postmenopausal patients presenting with manifestations of a breast abscess, especially in those who respond poorly to the initial treatment. Physicians should be aware of this rare malignancy in order to avoid delays in diagnosis and treatment.

    Molecular heterogeneity within primary breast carcinomas and among axillary lymph node (LN) metastases may impact diagnosis and confound treatment. In this study, we used short tandem repeated sequences to assess genomic heterogeneity and to determine hereditary relationships among primary tumor areas and regional metastases from 30 breast cancer patients. We found that primary carcinomas were genetically heterogeneous and sampling multiple areas was necessary to adequately assess genomic variability. LN metastases appeared to originate at different time periods during disease progression from different sites of the primary tumor and the extent of genomic divergence among regional metastases was associated with a less favorable patient outcome (P = 0.009). In conclusion, metastasis is a complex process influenced by primary tumor heterogeneity and variability in the timing of dissemination. Genomic variation in primary breast tumors and regional metastases may negatively impact clinical diagnostics and contribute to therapeutic resistance. PMID:26279627

    A systems model was developed to describe the metabolism and disposition of ursodeoxycholic acid (UDCA) and its conjugates in healthy subjects based on pharmacokinetic (PK) data from published studies in order to study the distribution of oral UDCA and potential interactions influencing therapeutic effects upon interruption of its enterohepatic recirculation. The base model was empirically adapted to patients with primary biliary cirrhosis (PBC) based on current understanding of disease pathophysiology and clinical measurements. Simulations were performed for patients with PBC under two competing hypotheses: one for inhibition of ileal absorption of both UDCA and conjugates and the other only of conjugates. The simulations predicted distinctly different bile acid distribution patterns in plasma and bile. The UDCA model adapted to patients with PBC provides a platform to investigate a complex therapeutic drug interaction among UDCA, UDCA conjugates, and inhibition of ileal bile acid transport in this rare disease population. © 2016 The Authors CPT: Pharmacometrics & Systems Pharmacology published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

  13. Mesenchymal Stem Cells as New Therapeutic Agents for the Treatment of Primary Biliary Cholangitis

    Directory of Open Access Journals (Sweden)

    Aleksandar Arsenijevic

    2017-01-01

    Full Text Available Primary biliary cholangitis (PBC is a chronic autoimmune cholestatic liver disease characterized by the progressive destruction of small- and medium-sized intrahepatic bile ducts with resultant cholestasis and progressive fibrosis. Ursodeoxycholic acid and obethicholic acid are the only agents approved by the US Food and Drug Administration (FDA for the treatment of PBC. However, for patients with advanced, end-stage PBC, liver transplantation is still the most effective treatment. Accordingly, the alternative approaches, such as mesenchymal stem cell (MSC transplantation, have been suggested as an effective alternative therapy for these patients. Due to their immunomodulatory characteristics, MSCs are considered as promising therapeutic agents for the therapy of autoimmune liver diseases, including PBC. In this review, we have summarized the therapeutic potential of MSCs for the treatment of these diseases, emphasizing molecular and cellular mechanisms responsible for MSC-based effects in an animal model of PBC and therapeutic potential observed in recently conducted clinical trials. We have also presented several outstanding problems including safety issues regarding unwanted differentiation of transplanted MSCs which limit their therapeutic use. Efficient and safe MSC-based therapy for PBC remains a challenging issue that requires continuous cooperation between clinicians, researchers, and patients.

    Patients with autoimmune hepatitis (AIH) who have antibodies against mitochondrial proteins (AMA positive) are believed to have an autoimmune syndrome that should be managed as AIH. Of patients with AMA-positive AIH, we report on 3 individuals to demonstrate how autoimmune liver disease can progress over time. Specific features of primary biliary cirrhosis (PBC) overlapped in time in these patients. Our observations indicate the importance of careful follow up of patients with AMA-positive AIH; health care professionals that treat such patients should therefore be aware of longitudinal clinical changes that might indicate development of PBC in this setting.

    Foreign bodies in the biliary tree are rare causes of obstructive jaundice. Food bezoars are infrequent as well. They can cause biliary obstruction after biliary tract interventions, or in the presence of biliary-bowel fistula or duodenum diverticulum. Food bezoars usually pass the gastrointestinal tract without any symptoms, but they can cause abdominal pain and obstructive jaundice in the case of biliary tract obstruction.

    Summary Background The aim of this study was to assess short- and long-term outcomes of malignant biliary obstruction (MBO) treatment by percutaneous transhepatic biliary stenting (PTBS) with uncovered selfexpandable metallic stents (SEMS), and to identify predictors of survival. Material/Methods A nine-year, single-centre study from a prospectively collected database included 222 patients with inoperable MBO treated by PTBS with uncovered nitinol SEMS. Results Technical and clinical success rates were 95.9% and 82.4%, respectively. The total rate of postprocedural complications was 14.4%. The mean durations of the primary and secondary stent patency were 114.7±15.1 and 146.4±21.2 days, respectively. The 30-day mortality rate was 15.3% with no procedure-related deaths. The mean estimated length of survival was 143.3±20.6 days. Independent predictors increasing the risk of death included higher than 115 μmol/L serum bilirubin 2–5 days after biliary stenting (HR 3.274, P=0.019), distal (non-hilar) obstruction of the bile ducts (HR 3.711, P=0.008), Bismuth-Corlette type IV stricture (HR 2.082, P=0.008), obstruction due to gallbladder cancer (HR 31.029, P=0.012) and only partial drainage of liver parenchyma (HR 4.158, P=0.040). Conclusions PTBS with uncovered SEMS is an effective and safe method for palliative treatment of MBO. Serum bilirubin higher than 115 μmol/L 2–5 days after the procedure has a significant negative impact on patients’ survival. Lower survival is also determined by distal bile duct obstruction, Bismuth– Corlette type IV stricture, biliary obstruction caused by gallbladder cancer and when only partial liver drainage is applied.

    Full text: To determine the overall survival and gastrointestinal toxicity for patients treated with salvage definitive chemo-radiotherapy after primary surgery for locoregional relapse of oesophageal carcinoma. A retrospective review of 525 patients who had a resection for oesophageal or oesophagogastric carcinoma at Princess Alexandra Hospital identified 14 patients treated with salvage definitive radiotherapy or chemo-radiotherapy, following localized recurrence of their disease. We analysed the patient and treatment characteristics to determine the median overall survival as the primary end point. Gastrointestinal toxicity was examined to determine if increased toxicity occurred when the stomach was irradiated within the intrathoracic radiotherapy field. The median overall survival for patients treated with curative intent using salvage definitive chemo-radiotherapy was 16 months and the 2-year overall survival is 21%. One patient is in clinical remission more than 5 years after therapy. Age <60 years old and nodal recurrence were favourable prognostic factors. Treatment compliance was 93% with only one patient unable to complete the intended schedule. Fourteen per cent of patients experienced grade 3 or 4 gastrointestinal toxicity. Salvage definitive chemo-radiotherapy should be considered for good performance status patients with oesophageal carcinoma who have a locoregional relapse after primary surgery. The schedule is tolerable with low toxicity and an acceptable median survival

    Full Text Available Neuroendocrine carcinoma of the breast (NECB is a subtype of breast cancer. The diagnostic criteria of primary NECB were established in 2003 and updated in 2012. It is a rare entity, and few studies have reported the histogenesis, immunohistochemistry for a pathological diagnosis, clinical behavior, therapeutic strategies, and the prognostic factors. Because of the rarity of this disease, consistent diagnostic criteria will remind physicians of this disease when making a differential diagnosis to enable a timely diagnosis and prompt treatment. Herein, we report a case of primary NECB who presented with a history of right hip pain arising from an osteolytic lesion in the right acetabulum and ischium. The course of investigation started with metastasis in the right hip and concluded with a diagnosis of NECB. In addition to the case report, we also conducted a literature review.

    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.

    Some patients with primary biliary cirrhosis (PBC) have antinuclear antibodies (ANAs). These ANAs include the "multiple nuclear dots" (MND) staining pattern, targeting promyelocytic leukemia protein (PML) nuclear body (NB) components, such as "speckled 100-kD" protein (Sp100) and PML. A new PML NB protein, designated as Sp140, was identified using serum from a PBC patient. The aim of this study was to analyze the immune response against Sp140 protein in PBC patients. We studied 135 PBC patients and 157 pathological controls with type 1 autoimmune hepatitis, primary sclerosing cholangitis, and systemic lupus erythematosus. We used indirect immunofluorescence and a neuroblastoma cell line expressing Sp140 for detecting anti-Sp140 antibodies, and a commercially available immunoblot for detecting anti-Sp100 and anti-PML antibodies. Anti-Sp140 antibodies were present in 20 (15%) PBC patients but not in control samples, with a higher frequency in antimitochondrial antibody (AMA)-negative cases (53 vs. 9%, P<0.0001). Anti-Sp140 antibodies were found together with anti-Sp100 antibodies in all but one case (19 of 20, 90%) and with anti-PML antibodies in 12 (60%) cases. Anti-Sp140 positivity was not associated with a specific clinical feature of PBC. Our study identifies Sp140 as a new, highly specific autoantigen in PBC for the first time. The very frequent coexistence of anti-Sp140, anti-Sp100 and anti-PML antibodies suggests that the NB is a multiantigenic complex in PBC and enhances the diagnostic significance of these reactivities, which are particularly useful in AMA-negative cases.

    Objective: To investigate the diagnostic value of combined detection of four tumor markers in patients with possible malignant change in liver disorders. Methods: Serum AFP, CEA, CA199 and SF levels were determined with chemiluminescence immunoassay (CLIA) in 49 patients with primary liver carcinoma, 7 patients with metastatic liver carcinoma, 40 patients with hepatic cirrhosis, 47 patients with HBV hepatitis and 30 controls. Results: The serum levels of AFP, CEA, SF in patients with primary hepatic cancer and serum levels of AFP, SF in patients with hepatic cirrhosis were all significantly higher than those in controls (P 0.05). Moreover, positive rate of combined determination of AFP, CEA, CA199, SF in patients with primary hepatic cancer was significantly higher than that in patients with metastatic liver cancer. Conclusion: With combined determination of these four tumor markers, the detection rate of primary hepatic carcinoma could be enhanced to above 95%. Also, differential diagnosis between primary and metastatic hepatic cancers could be facilitated. (authors)

  4. Management of Benign Biliary Strictures

    2002-01-01

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

    The purpose of this study was to investigate the accuracy of hepatobiliary scintigraphy (HBS) in the diagnosis of segmental or total biliary obstruction during long-term follow-up period after curative radical surgery with biliary-enteric anastomosis. The study population included 80 patients who underwent biliary-enteric anastomoses for benign (n=33) or malignant (n=47) biliary disease. Fifty-six of these 80 patients also underwent curative hepatic resection. Ninety eight hepatobiliary scintigrams using {sup 99m}Tc-DISIDA were performed at least 1 month after surgery (median 9 month). The scintigraphic criteria of total biliary obstruction we used were intestinal excretion beyond one hour or delayed hepatobiliary washout despite the presence of intestinal excretion. Segmental biliary obstruction was defined as delayed segmental excretion. The accuracy for biliary obstruction was evaluated according to different clinical situations. There were 9 instances with total biliary obstruction and 23 with segmental bile duct obstruction. Diagnosis of biliary obstruction was confirmed by percutaneous transhepatic cholangiography or surgery in 13, and follow-up clinical data for at least 6 months in 19 instances. Among the 32 instances with biliary symptoms and abnormal liver function, HBS allowed correct diagnosis in all 32(9 total, 14 segmental obstruction and 9 non-obstruction). Of the 40 with nonspecific symptom or isolated elevation of serum alkaline phosphatase, HBS diagnosed 8 of the 9 segmental biliary obstruction and 30 of the 31 non-obstruction. There were no biliary obstruction and no false positive result of scintigraphy in 26 instances which had no clinical symptom or signs of biliary obstruction. Diagnostic sensitivity of HBS was 100% (9/9) for total biliary obstruction, and 96%(22/23) for segmental bile obstruction. Specificity was 98%(39/40) in patients who had abnormal symptom or sign. Hepatobiliary scintigraphy is a highly accurate modality in the

    Recent advances in chemoradiotherapy for esophageal carcinoma have resulted in improved survival rates. However, there are few options for recurrent dysphagia due to refractory carcinoma after failure of primary chemoradiotherapy. The aim of this study was to evaluate the safety and efficacy of self-expandable metallic stent placement for patients with recurrent esophageal carcinoma where definitive chemoradiotherapy has failed. Thirteen consecutive patients with recurrent squamous cell carcinoma of the esophagus, in whom self-expandable metallic stents were placed after failure of primary chemoradiotherapy, were studied retrospectively. All patients had esophageal obstruction or malignant fistula. The oral alimentation status of nine of 13 patients (69%) improved after successful placement of the stent. Following placement of the stent, fever (>38 deg C) and severe chest pain occurred in 85% (11/13) of the patients. In all patients examined, C-reactive protein was elevated within 1 week of the operation. Esophageal perforation occurred in three patients. Stent-related mediastinitis and pneumonia developed in six (46%) and three (23%) patients, respectively. Seven of the 13 patients (54%) died of stent-related pulmonary complications. Although the placement of a self-expandable metallic stent for patients with recurrent esophageal carcinoma after failure of chemoradiotherapy improved their oral alimentation status, we found that this treatment increases the risk of life-threatening pulmonary complications.

    Qaiser Jalal

    Full Text Available Background: Managing choledochotomy after bile duct clearance is an ongoing debate. T-tube insertion is not without complication and morbidity, requires significant post-operative care. Primary closure alone can result in a high pressure biliary system and bile leak. The placement of an ante-grade stent through the choledochotomy prior to primary closure is an option for ensuring biliary drainage after bile duct exploration. We reviewed our series of open bile duct explorations, where an ante-grade stent was placed when managing choledochotomy. Methods: Patients who had ante-grade stent placement, all performed by same senior hepatobiliary surgeon, were identified retrospectively. Case note review was used to gather demographic, complication, length of stay, post-operative clinic visits and readmission data. Results: 22 (M:F, 7:15 patients with a median age of 64 years (22–82. The indication for surgical stone clearance was failed ERCP in 20.2 patients were not suitable for ERCP. The median post-operative stay was 8 days (379 with the abdominal drain remaining for a median of 4 days (137. 16 (73% patients had no complications. 4 (18% had bile leaks, 5 (22% wound infections, 1 (5% cholangitis and 1 (5% pancreatitis. All complications were Clavien-Dindo grade 3 or less. Conclusion: In situations where primary CBD closure is not safe due to concern over high pressure in the biliary tree the placement of ante-grade stent may be preferred to T-tube placement.

    Objective: To evaluate multislice CT in the diagnosis of biliary complications after liver transplantation. Methods: Eighty-three consecutive patients who had undergone orthotopic liver transplantation (OLT) presented with clinical or biochemical signs of biliary complications and underwent contrast-enhancement CT examination. Three experienced radiologists, who were blinded to patient's clinical data, assessed CT images for the detection of biliary complications in consensus. Diagnostic confirmation of biliary complications was obtained with direct cholangiography in 69 patients, histologic study in 11 patients and hepaticojejunostomy in 3 patients. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CT for the detection of biliary complications were calculated. In addition, CT features of anastomotic biliary stricture (ABS) were compared with those of non-anastomotic biliary stricture (NABS) using χ 2 test. Results: A total of 62 biliary complications (74.7%) was eventually confirmed in the 83 patients, including ABS in 32 patients, NABS in 21 patients, biliary duct stones in 16 patients (of which 12 patients with biliary stricture) , anastomotic bile leakage in 5 patients, biloma in 4 patients with biliary stricture, and biliogenic abscess in 2 patients with biliary stricture. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of CT for the detection of biliary stricture were 90.6%, 86.7%, 89.2%, 92.3% and 83.9%, respectively. Other biliary complications, including biliary duct stones (16 cases), anastomotic bile leak (5 cases), biloma (4 cases), and biliogenic abscess (2 cases), were correctly diagnosed by CT; there was no false-positive or false-negative result. The incidence of irregular dilatation of bile duct was 71.4% (15/21), which was significantly higher in NABS cases than in ABS of 25.0% (8/32, P<0.01); whereas the incidence of extrahepatic biliary dilatation

    Full Text Available Renal cell carcinoma is known to cause metastasis to unusual sites, which can be both synchronous or metachronous. Thyroid gland is a rare site for metastasis, but when it occurs, renal cell carcinoma is the most common primary neoplasm. We report the case of a 81-year-old female patient who had a significant medical history of right clear cell renal carcinoma with adrenal metastasis. She underwent right radical nephrectomy and adrenalectomy followed by radiofrequency ablation of left adrenal metastasis and systemic chemotherapy with sunitinib. Eleven years later, she presented with dysphagia and was found to have distal esophageal adenocarcinoma. On imaging, there was incidental detection of a left renal mass lesion and a right thyroid nodule, which on histopathology and immunohistochemistry were confirmed to be clear cell carcinoma of renal origin.

    The hypothesis of this study is that fisetin and phase II conjugated forms of fisetin may partly undergo biliary excretion. To investigate this hypothesis, male Sprague-Dawley rats were used for the experiment, and their bile ducts were cannulated with polyethylene tubes for bile sampling. The pharmacokinetic results demonstrated that the average area-under-the-curve (AUC) ratios ( k (%) = AUC conjugate /AUC free-form ) of fisetin, its glucuronides, and its sulfates were 1:6:21 in plasma and 1:4:75 in bile, respectively. Particularly, the sulfated metabolites were the main forms that underwent biliary excretion. The biliary excretion rate ( k BE (%) = AUC bile /AUC plasma ) indicates the amount of fisetin eliminated by biliary excretion. The biliary excretion rates of fisetin, its glucuronide conjugates, and its sulfate conjugates were approximately 144, 109, and 823%, respectively, after fisetin administration (30 mg/kg, iv). Furthermore, biliary excretion of fisetin is mediated by P-glycoprotein.

    Full Text Available Squamous cell carcinoma (SCC of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year’s duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up.

    Cystic duplications of the biliary tract are rare anomalies, easily mistaken for choledochal cysts. Surgical drainage is the preferred therapy for choledochal cyst, but cystic duplication necessitates surgical excision as duplications may contain heterotopic gastric mucosa leading to peptic ulceration of the biliary tract. We report a case of biliary tract duplication cyst containing heterotopic alimentary mucosa which had initially been diagnosed and surgically treated as a choledochal cyst.

Various patient related and technical factors are implicated in the causation of biliary injuries. Over a period of twenty five years managing such patients of biliary injuries our team has found a practical approach to assess the cause of biliary injuries based on the symptoms, clinical examination and imaging. Bismuth classification is helpful in most of the cases. Immediate referral to a centre experienced in the management of bile duct injury and timely intervention is associated with improved outcomes. Resuscitation, correcting dyselectrolytemia, aspiration of undrained biloma and antibiotics take the priority in the management. The goal is to restore the bile conduit, and to prevent short and longterm complications such as biliary fistula, intra-abdominal abscess, biliary stricture, recurrent cholangitis and secondary biliary cirrhosis. Endoscopic therapy by reducing the transpapillary pressure gradient helps in reducing the leak. Endoscopic therapy with biliary sphincterotomy alone or with additional placement of a biliary stent/ nasobiliary drainage is advocated. In our tertiary care referral unit, we found endoscopic interventions are useful in situations where there is leak with associated CBD calculus or a foreign body, peripheral bile duct injury, cystic duct stump leak and partial bile duct injury with leak/ narrowing of the lumen. Endotherapy is not useful in case of complete transection (total cut off and complete stricture involving common hepatic or common bile ducts. In conclusion, endoscopic treatment can be considered a highly effective therapy and should be the first-line therapy in such patients. Though less successful, an endoscopic attempt is warranted in patients suffering from central bile duct leakages failing which surgical management is recommended.

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

    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.

    Merkel cell carcinoma (MCC) is a rare and highly aggressive neuroendocrine tumor of the skin which almost exclusively presents as a solitary tumor. It is most often seen on sun-exposed regions, historically almost exclusively on the head and neck, with only rare case reports on the extremities. Although recent studies have shown increased incidence with up to 20% on the extremities, here we present one of these rare emerging presentations, with the addition of a unique treatment option. Our patient is an 80-year-old male with a 3-month history of multiple raised, rapidly enlarging tumors on the right ankle. Two separate biopsies were performed and demonstrated sheets and clusters of small blue cells filling the dermis with scant cytoplasm, dusty chromatin, and nuclear molding. Subsequent immunohistochemical stains confirmed the diagnosis of multiple primary MCC. Despite the characteristic immunohistochemical profile of primary MCC, the possibility of a metastatic neuroendocrine carcinoma from an alternate primary site was entertained, given his unusual clinical presentation. A complete clinical workup including CT scans of the chest, abdomen, and pelvis showed no evidence of disease elsewhere. Instead of amputation, the patient opted for nonsurgical treatment with radiation therapy alone, resulting in a rapid and complete response. This case represents an unusual presentation of primary MCC and demonstrates further evidence that radiation as monotherapy is an effective local treatment option for inoperable MCC. PMID:26594171

    To examine diurnal variation in biliary excretion of flomoxef. Flomoxef (1 g) was injected intravenously in eight patients with percutaneous transhepatic cholangiography with drainage at 09.00 h and 21.00 h by a cross-over design with a 36 h washout period. Drained biliary fluid was collected for 6 h after each dosing. These patients still had mild to moderate hepatic dysfunction. Bile flow and bile acid excretion for 6 h after dosing did not differ significantly between the 09.00 h and 21.00 h treatments. The maximum concentration of biliary flomoxef was significantly greater and its total excretion for 6 h tended to be greater after the 21.00 h dose [maximum concentration (microg ml(-1)): 34.2 +/- 29.9 (09.00 h dose) vs 43.5 +/- 28.3 (21.00 h dose) (95% confidence interval for difference: 2.6 approximately 15.9, P = 0.013); total excretion (mg 6 h(-1)): 1.4 +/- 1.3 (09.00 h dose) vs 1.6 +/- 1.2 (21.00 h dose) (95% confidence interval for difference: -26.8, 313.7, P = 0.087)]. The period that biliary flomoxef remained above the minimal inhibitory concentration did not differ significantly between the two treatment times. These results suggest that biliary excretion of flomoxef shows diurnal variation. However, as the difference was relatively small, flomoxef could be given at any time of day without any dosage adjustments.

    Primary ectopic breast carcinoma is a rare disease and, at present, no specific guidelines on its diagnosis and treatment are available. The purpose of this article is to review the world literature in English on primary ectopic breast carcinoma located in the armpit and to offer guidelines for diagnosis and treatment. Data for this review were identified by searches of MEDLINE, PubMed, The Cochrane Library, ACNP (Italian catalogue of journals) and references from relevant articles using relevant search terms and data published in the previous reviews. Primary ectopic breast carcinoma of the axilla mostly affects women of over 40 (range 28-90 yrs) years of age. The most frequent histological diagnosis is invasive ductal carcinoma not otherwise specified (NOS) (72%). Because of its rareness, in most cases, the diagnosis is delayed for on average 40.5 months. This disease is rare, but a high level of suspicion for carcinoma is mandatory when confronted with a tumour in this area. Once diagnosed, patients should undergo staging, and prognostic and adjuvant treatment procedures identical to orthotopic breast carcinoma guidelines. There are some limitations for the staging. Loco-regional treatment, on indication, combined with endocrine therapy and/or chemotherapy seems the treatment of choice.

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

    Carcinoma of the biliary tract is a rare tumour. To date, there is no therapeutic measure with curative potential apart from surgical intervention. Thus, patients with advanced, i.e. unresectable or metastatic disease, face a dismal prognosis. They present a difficult problem to clinicians as to whether to choose a strictly supportive approach or to expose patients to the side-effects of a potentially ineffective treatment. The objective of this article is to review briefly the clinical trials available in the current literature utilising non-surgical oncological treatment (radiotherapy and chemotherapy) either in patients with advanced, i.e. locally inoperable or metastatic cancer of the biliary tract or as an adjunct to surgery. From 65 studies identified, there seems to be no standard therapy for advanced biliary cancer. Despite anecdotal reports of symptomatic palliation and survival advantages, most studies involved only a small number of patients and were performed in a phase II approach. In addition, the benefit of adjuvant treatment remains largely unproven. No clear trend in favour of radiation therapy could be seen when the studies included a control group. In addition, the only randomised chemotherapeutic series seemed to suggest a benefit of treatment in advanced disease, but due to the small number of patients included, definitive evidence from large, randomised series concerning the benefit of non-surgical oncological intervention as compared with supportive care is still lacking. Patients with advanced biliary tract cancer should be offered the opportunity to participate in clinical trials. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam. All rights reserved.)

    Biliary stents are widely used not only for palliative treatment of malignant biliary obstruction but also for benign biliary diseases. Each plastic stent or self-expandable metal stent (SEMS) has its own advantages, and a proper stent should be selected carefully for individual condition. To compensate and overcome several drawbacks of SEMS, functional self-expandable metal stent (FSEMS) has been developed with much progress so far. This article looks into the outcomes and defects of each stent type for benign biliary stricture and describes newly introduced FSEMSs according to their functional categories. PMID:24143314

  10. Liver stem/progenitor cells in the canals of Hering: cellular origin of hepatocellular carcinoma with bile duct tumor thrombi?

    It is generally believed that the invasion of hepatocellular carcinoma (HCC) into the biliary tree ultimately leads to the formation of bile duct tumor thrombi (BDTT). However, recent studies revealed that primary tumor might be small, even undetectable, and there was no histopathologic evidence of direct tumor invasion into bile duct wall in some patients. During the last decade, efforts on stem cell biology may shed light on the pathogenesis of BDTT. Presently, accumulating evidence supports the following notions: (1) the canals of Hering (CoH) are the most likely origin of liver stem/progenitor cells (LSPCs) in adult livers; (2) similar signalling pathways may regulate self-renewal in LSPCs and liver cancer cells, and a substantial proportion of liver tumors may often originate from the transformation of LSPCs; and (3) liver cancer contains rare cells with stem cell-like properties, which could derive from malignant transformation of LSPCs. Herein, we propose that HCC with BDTT, especially with small or undetectable primary lesion and/or no histopathologic evidence for bile duct invasion, might arise from LSPCs residing in the CoH and, possibly, some primary lesions are formed firstly within the intrahepatic biliary tree. When "tumor thrombi" extends mainly along bile duct, there might be "BDTT" alone; when it invades into surrounding parenchyma, there might often be small "primary tumor" with "BDTT". If this holds true, the putative type may be a particular subset of HCC, and most importantly it would facilitate our understanding of stem-cell origin of HCC.

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

    To examine the state of the biliary system, a study of properties of bile "case-control") 100 children and adolescents aged 8 to 18 years, held checkup in consultative and diagnostic center for chronic gastroduodenitis. BMI children were divided into 2 groups: group 1-60 children with obesity (BMI of 30 to 40) and group 2-40 children with normal anthropometric indices. Survey methods included clinical examination pediatrician, endocrinologist, biochemical parameters (ALT, AST, alkaline phosphatase level, total protein, bilirubin, lipidogram, glucose, insulin, HOMA-index), ultrasound of the abdomen and retroperitoneum, EGD with aspiration of gallbladder bile. Crystallography bile produced by crystallization of biological substrates micromethods modification Prima AV, 1992. Obese children with chronic gastroduodenita more likely than children of normal weight, had complaints and objective laboratory and instrumental evidence of insulin resistance and motor disorders of the upper gastrointestinal and biliary tract, liver enlargement and biliary "sludge". Biochemical parameters of obese children indicate initial metabolic changes in carbohydrate and fat metabolism and cholestasis, as compared to control children. Colloidal properties of bile in obese children with chronic gastroduodenita reduced, as indicated by the nature of the crystallographic pattern. Conclusions: Obese children with chronic gastroduodenitis often identified enlarged liver, cholestasis and biliary dysfunction, including with the presence of sludge in the gallbladder; most often--hypertonic bile dysfunction. Biochemical features of carbohydrate and fat metabolism reflect the features of the metabolic profile of obese children. Crystallography bile in obese children reveals the instability of the colloidal structure of bile, predisposing children to biliary sludge, which is a risk factor for gallstones.

    Endoscopic retrograde cholangiography (ERCP) is currently standard treatment for biliary drainage. Endoscopic ultrasound guided rendezvous (EUS-RV) is a novel method to overcome an unsuccessful biliary drainage procedure. Under endoscopic ultrasound guidance a guidewire is passed via a needle from the stomach or duodenum to the common bile duct and from there on to the duodenum enabling ERCP. With a relatively high rate of success EUS-RV should be considered as an alternative to biliary drainage and surgical intervention.

    Merkel cell carcinoma (MCC) is an aggressive poorly differentiated neuroendocrine cutaneous carcinoma associated with older age, immunodeficiency and Merkel cell polyomavirus (MCPyV) integrated within malignant cells. The presence of intra-tumoural CD8+ lymphocytes reportedly predicts better MCC-specific survival. In this study, the distribution of inflammatory cells and properties of CD8+ T lymphocytes within 20 primary MCC specimens were characterised using immunohistochemistry and multicolour immunofluorescent staining coupled to confocal microscopy. CD8+ cells and CD68+ macrophages were identified in 19/20 primary MCC. CD20+ B cells were present in 5/10, CD4+ cells in 10/10 and FoxP3+ cells in 7/10 specimens. Only two specimens had almost no inflammatory cells. Within specimens, inflammatory cells followed the same patchy distribution, focused at the edge of sheets and nodules and, in some cases, more intense in trabecular areas. CD8+ cells were outside vessels on the edge of tumour. Those few within malignant sheets typically lined up in fine septa not contacting MCC cells expressing MCPyV large T antigen. The homeostatic chemokine CXCL12 was expressed outside malignant nodules whereas its receptor CXCR4 was identified within tumour but not on CD8+ cells. CD8+ cells lacked CXCR3 and granzyme B expression irrespective of location within stroma versus malignant nodules or of the intensity of the intra-tumoural infiltrate. In summary, diverse inflammatory cells were organised around the margin of malignant deposits suggesting response to aberrant signaling, but were unable to penetrate the tumour microenvironment itself to enable an immune response against malignant cells or their polyomavirus.

    Primary biliary cirrhosis (PBC) is frequently associated with other autoimmune diseases, including systemic sclerosis (SSc). In the last years many efforts have been dedicated to the research of widely accepted criteria for the early diagnosis of SSc. Since studies on the prevalence of early SSc in PBC patients are lacking, our aim was to investigate its hitherto unknown prevalence in a large cohort of PBC patients. We studied 80 PBC patients and 72 patients with other chronic liver diseases. Diagnostic workup included research into signs of connective tissue disease, determination of autoantibody profile, and examination of capillary abnormalities through nailfold videocapillaroscopy. Ten PBC patients (12.5%) satisfied diagnostic criteria for early SSc and 5 (6.3%) had definite SSc. None of the patients in the control group were diagnosed either with early or definite SSc. No differences were observed in terms of aminotransferases, alkaline phosphatase, and liver function tests between PBC patients with and without associated SSc. Early SSc is significantly frequent in PBC patients. The detection of early SSc in PBC patients may lead to a prompt treatment of its complications, preventing inabilities and preserving the chance of liver transplantation.

    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.

    2015-04-01

    Merkel cell nodal carcinoma of unknown primary (MCCUP) is a rare neuroendocrine tumour with distinct clinical and biological behaviour. We conducted a review of retrospective data extracted from 90 patients focusing on the management and outcome of this disease. We also compared life expectancy of these patients with the outcome of patients with known Merkel primaries and with neuroendocrine cancers of unidentifiable primary. There is a limited body of data for this type of malignancy, however, patients with Merkel cell nodal carcinoma of unknown primary site, seem to have better survival when treated aggressively than patients with cutaneous Merkel tumours of the same stage and equal survival with patients with low-grade neuroendocrine tumour of unknown origin. The lack of prospective trials, and the inadequate data, hamper the management of these tumours. Establishment of treatment guidelines is urgently needed. Copyright © 2014 Elsevier Ireland Ltd.

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

    Primary gastric carcinoma is the most common cause of linitis plastica. Less frequently, metastatic gastric cancer from the breast, omental metastases and non-Hodgkin lymphoma involving the stomach have been reported to show similar radiographic findings as for linitis plastica. A metastatic gastric cancer from bladder cancer is extremely rare. We present an unusual case, the first to our knowledge, of gastric linitis plastica that resulted from a metastatic urothelial carcinoma of the bladder

    Full Text Available Primary carcinoma of the fallopian tube is rare and accounts for about 0.14-1.8% of all gynecological malignancies. Correct diagnosis is rarely made preoperatively as clinically tubal carcinoma closely resembles ovarian carcinoma. Here, we report two cases of bilateral primary fallopian tube carcinomas. Case 1: A 54-year-old female presented with postmenopausal bleeding, abdominal pain, and pervaginal watery discharge for 10 days. Ultrasonography (USG of pelvis showed endometrial thickening and multiple tiny echogenic foci in omentum suggestive of omental cake. With a provisional diagnosis of endometrial carcinoma, total abdominal hysterectomy with bilateral salpingo-oophorectomy and omentectomy was done. On gross examination, small and rudimentary right ovary was adherent to the fimbrial end of the tube. Left-sided tubo-ovarian mass was present, cut section of which showed yellowish solid area in tubal wall and encroaching on ovarian surface. On histological examination, sections from the fimbrial end of both fallopian tubes showed features of papillary serous adenocarcinoma. Case 2: 70-year-old lady, 15 years postmenopausal presented with gradual onset pain and swelling of abdomen, urinary incontinence since 4 days. USG showed bulky uterus, 5 cm × 2 cm fibroid, bilateral tubes, and ovaries were not visualized. Serum cancer antigen-125 was raised (159.7 U/ml. Total hysterectomy and bilateral salpingo-oophorectomy with infracolic omentectomy was done. On gross examination, ovaries were firmly attached to tubes and no apparent solid area was noted. On microscopy, papillary serous adenocarcinoma arising from tubal wall was seen infiltrating focally into ovarian stroma; tubal epithelium showed dysplastic change. Sections from omentum showed numerous psammoma bodies.

    Full Text Available Portal biliary ductopathy (PBD is a condition in which biliary and pancreatic ducts are extrinsically compressed by collateral branches of the portal venous system, which in turn have become dilated and varicosed due to portal hypertension. While the majority of patients with PBD are asymptomatic, a minority can present with symptoms of biliary obstruction and cholangitis with the potential of developing secondary chronic liver disease. This paper reports the case of a 29 year old male presenting with acute cholangitis, in whom PBD was diagnosed radiologically. A brief review of current literature regarding the diagnosis and management of this condition will also be presented.

    1984-01-01

    Sixty-two patients with primary carcinoma of the female urethra were treated with a combined radiation therapy (high-dose intracavitary vaginal radium and external beam). Treatment was strictly individualized, but an administered tumor dose of 5500-7000 rad (55-70 Gy) was always attempted. Forty-two patients (67.7%) had tumors of the anterior urethra, and in 20 women (32.3%) the posterior urethra was involved. In 19 patients (30.6%) the clinical diagnosis of lymph node involvement was made. The overall 5-year-survival rate was 64.5%. Patients with anterior urethral carcinoma had a higher 5-year-survival rate (71.4%) than patients with posterior carcinoma (50.0%). The favorable results underline the substantial role of radiation therapy for this malignancy.

    We report a trial of MR cholangiography in children with choledochal cyst. Recently, three-dimensional reconstruction using magnetic resolution imaging of biliary system (MR cholangiography) has been reported as the less-invasive diagnostic method for obstructive lesions of biliary system. Forty-eight cases of choledochal cyst were treated at Kagoshima University Hospital in the past ten years. In 22 of them, intrahepatic duct dilatation was revealed by preoperative or operative cholangiogram. We tried MR cholangiography in nine cases of 22 cases pre- and/or post-operatively. Five cases had MR cholangiography preoperatively. Intrahepatic biliary dilatation was revealed in all of them and intrahepatic biliary stenosis was revealed in two cases. These findings were almost the same as those by preoperative or operative cholangiogram. MR cholangiography was applied on seven cases postoperatively: 3 cases had fine construction of biliary system, because they still had intrahepatic biliary dilatation, and no dilatation was seen in 4 cases, because of good operative results. This method has advantages of less-invasive in children, no need of contrast dye, and fair delineation of biliary system as samely as endoscopic retrograde cholangiography (ERCP) and percutaneous transhepatic cholangiography (PTC). In cases of huge biliary dilatation, MR cholangiography provides more information concerning intrahepatic biliary than ERCP. (author)

    Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare carcinoma, which arises within the jaws without connection to the oral mucosa and presumably develops from a remnant of odontogenic epithelium. We present a case of solid type PIOSCC in a 52-year-old male patient complaining of dull pain on his left lower molar. In this case, early stage PIOSCC mimicking a periapical lesion might lead to a one-year delay in treatment due to the misdiagnosis of osteomyelitis after extraction of the third molar. The clinical, radiological, and histologic features are described. In this case, there was initial radiographic evidence for PIOSCC mimicking a periapical lesion. Incautious radiographic interpretation and treatment procedures had delayed the correct diagnosis and resulted in extensive bony destruction during the patient's disease progression.

    Full Text Available Primary squamous cell carcinoma of the breast (SCCB is a very rare malignancy of the breast and is generally aggressive. It is even rarer during the gestational period. Only few cases have been reported during pregnancy and lactation (Rokutanda et al., 2000. SCCB seen within the gestational period tends to be very aggressive and has a larger size than other breast carcinomas. Pure SCCB is derived from the epidermis of the breast, nipple, or metaplasia on chronic inflammatory background (Bige et al., 2007, such as complicated breast cyst, dermoid cyst, or abscess. We report a case of SCCB in a 30-year-old primigravida that had an aggressive propensity and fatal outcome.

    Full Text Available Merkel cell carcinoma (MCC is a rare and highly aggressive neuroendocrine tumor of the skin which almost exclusively presents as a solitary tumor. It is most often seen on sun-exposed regions, historically almost exclusively on the head and neck, with only rare case reports on the extremities. Although recent studies have shown increased incidence with up to 20% on the extremities, here we present one of these rare emerging presentations, with the addition of a unique treatment option. Our patient is an 80-year-old male with a 3-month history of multiple raised, rapidly enlarging tumors on the right ankle. Two separate biopsies were performed and demonstrated sheets and clusters of small blue cells filling the dermis with scant cytoplasm, dusty chromatin, and nuclear molding. Subsequent immunohistochemical stains confirmed the diagnosis of multiple primary MCC. Despite the characteristic immunohistochemical profile of primary MCC, the possibility of a metastatic neuroendocrine carcinoma from an alternate primary site was entertained, given his unusual clinical presentation. A complete clinical workup including CT scans of the chest, abdomen, and pelvis showed no evidence of disease elsewhere. Instead of amputation, the patient opted for nonsurgical treatment with radiation therapy alone, resulting in a rapid and complete response. This case represents an unusual presentation of primary MCC and demonstrates further evidence that radiation as monotherapy is an effective local treatment option for inoperable MCC.

    Techniques that preserve the right hepatic artery and the common bile duct in continuity during the dissection may be associated with lower rates of biliary complications in living-donor liver transplants. This study sought to determine whether en bloc hilar dissections were associated with fewer biliary complications in living-donor liver transplants. This was a retrospective review of 41 adult LDLTs performed in a single, liver transplant center between February 2007 and September 2014. The primary outcome of interest was the occurrence of at least one of the following biliary complications: anastomotic leak, stricture, or biloma. The primary predictor of interest was the hilar dissection technique: conventional hilar dissection vs. en bloc hilar dissection. A total of 41 LDLTs were identified, 24 had a conventional, and 17 an en bloc hilar biliary dissection. The occurrence of any biliary complication was significantly more common in the conventional hilar dissection group compared to the en bloc hilar dissection group (66.7 vs. 35.3%, respectively, p = 0.047). In particularly, anastomotic strictures were significantly more common in the conventional hilar dissection group compared to the en bloc hilar dissection group (54.2 vs. 23.5%., respectively, p = 0.049). En bloc hilar dissection technique may decrease biliary complication rates in living donor liver transplants.

    Male breast cancer is a rare entity accounting for Nipple skin/subcutaneous tumors in men are even rarer. Likewise, true neuroendocrine carcinoma of the breast, defined as > 50% of tumor cells staining for either chromogranin or synaptophysin, is not a common entity, usually occurring in older women. We present the case of a 70-year-old man with a slowly growing nipple mass that had enlarged over the previous 1.5 years. The histology consisted of nests, trabeculae and sheets of basaloid cells with rare abortive gland formation and a pushing edge. The case was originally misdiagnosed as a Merkel cell carcinoma, based largely on histologic morphology. Strong staining for synaptophysin (in greater than 50% of cells), CD56, keratins AE1 : AE3 and Cam 5.2, as well as estrogen receptor and progesterone receptor was noted. Myoepithelial cells within in situ areas were identified using stains for calponin and 4A4, supporting a primary mammary duct origin. Additionally, a substantial portion of cells stained for Gross Cystic Disease Fluid Protein-15 (GCDFP-15), confirming some overlap with sweat duct differentiation. To the best of our knowledge, although reported in the male breast, no case of primary nipple neuroendocrine carcinoma in a male patient has been reported in the literature. The gender of the patient and association with the skin of the chest wall probably contributed to the original misdiagnosis of Merkel cell carcinoma in this patient.

  14. 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.

    Forty-three cases of primary vaginal squamous cell cancer were treated at the University of Wisconsin Hospital between 1956 and 1971. These cases comprised of 1.2% of patients admitted to the University Hospital with female genital tract cancer. Evidence is presented to support a modification of the currently accepted FIGO staging system for vaginal carcinoma (Stage II disease). Radiation therapy using both external beam and brachyradium equivalents or interstitial implantation of suitable isotopes was an effective method for the treatment of patients having early and locally advanced invasive vaginal cancer. The 5-year absolute survival rate for the entire series was 37.2%. Absolute survival rate by modified FIGO clinical staging was 66% for Stages I and IIA, 31% for Stage IIB, 25% for Stage III, and 0% for Stage IV

    This paper reports the case of a woman, who underwent surgery because of cholelithiasis, with intraoperative finding of prehepatic portal hypertension from portal vein thrombosis ("portal cavernoma") with healthy liver, later confirmed by angiographic studies. This rare pathologic association carries a higher risk of major operative complications; therefore the Authors agree with the general belief that, for these cases, biliary tract surgery should be as simple and safe as possible. In the case of preoperative diagnosis of biliary disease associated with portal cavernoma, should a surgical approach on the biliary tract be required, we agree on the advisability of performing a shunting procedure before any kind of biliary surgery. In case of variceal bleeding endoscopic sclerotherapy will be the first choice; surgical procedures (shunting) should be seen as a second choice in case of rebleeding after sclerotherapy.

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

    It is well known that realtime ultrasonography is the primary diagnostic modality to evaluate gallbladder diseases. The authors studied ultrasonographic findings of 10 pathologically proven gallbladder carcinoma patients, and it was compared with the findings of 4 cases of ERCP and 2 cases of CT which were performed at the same period. The results were as follows: 1. They were 6 males and 4 females with over 50 years of age except a 41 year old female. 2. The ultrasonographic classifications of the cases were 4 of fungating mass types, 3 of mass filling gallbladder types, 2 wall thickening types and 1 of mixed type, wall thickening and fungating mass. 3. Seven cases of cholecystitis, 6 cases of intrahepatic biliary duct dilatation, 5 cases of gallstone, 4 cases of common bile duct dilatation, 4 cases of sludge bile, 2 cases of gallbladder dilatation, 1 case of right sub phrenic and pericholecystic abscess due to perforated gallbladder. 4. Five cases of mesenteric infiltrations, 3 cases of hepatic infiltration adjacent to gallbladder, 2 cases of lymphatic metastasis to right lobe of liver and 2 cases of pericholedochal and pericaval lymph node metastasis. 5. The indistinct margin between gallbladder and surrounding organ adjacent to gallbladder mass or gallbladder wall thickening suggest cancer infiltration to adjacent organ such as liver or omentum. 6. If gallstone is engulfed in thickened gallbladder wall, the wall thickening suggests gallbladder carcinoma. 7. The differentiation between fungating mass and sludge bile, and the determination of mass could be done by positional change. 8. The preoperative ultrasonic diagnositc accuracy was in 9 out of 10 cases (90%). 9. Because of the frequent cystic duct obstruction by associated inflammation, the diagnostic accuracy of ERCP for gallbladder carcinoma was low.

    BACKGROUND AND STUDY AIMS: EUS-guided rendezvous technique for biliary access requires expert manipulation of the guidewire across the downstream stricture or papilla. Published literature reports usage of the long-wire system to prevent loss of wire during scope exchange. We studied the efficacy of using a short hydrophilic guidewire in EUS-guided rendezvous. PATIENTS AND METHODS: This is a retrospective study conducted in a tertiary care referral centre. 15 patients underwent EUS-guided biliary rendezvous with short wire. EUS-guided transduodenal/transgastric puncture of the biliary system was performed, followed by anterograde placement of a hydrophilic short-wire (260 cm) across the downstream stricture and/or papilla. Retrograde access was then achieved by retrieving the trans-papillary wire, followed by standard ERCP intervention. Main outcome measurements were rates of procedural success and complications. RESULTS: EUS-guided biliary rendezvous was successful in 14 patients (93.3%). Failure was seen in one patient due to a tight malignant biliary stricture. One patient had peri-choledochal bile tracking which did not require any specific treatment. CONCLUSIONS: Short-wire system in EUS-guided biliary rendezvous is highly effective and safe. It is a useful salvage procedure for biliary cannulation in patients with accessible papilla.

    1997-01-01

    Purpose: Percutaneous transhepatic insertion of biliary stent (PTIBS) was adopted for treating malignant and benign biliary stricture. The therapeutic effect, technique and complications were investigated. Materials and methods: Twenty-five patients with biliary stricture were treated by PTIBS, including hilar biliary cancer 16 cases, pancreatic cancer 4 cases, hilar metastatic cancer 3 cases, and post-operative biliary stricture of bile duct 2 cases. Results: The technical success rate was 96.0% (24/25). Two stents were placed in the right and left hepatic ducts respectively in 2 cases. The survival rate of 6 and 12 months were 73.3% and 46.6%. Restenosis rate was 40.0% in 6 months. Mild hemobilia (44.0%) and retrograde infection (8.0%) were the main complications which could be managed by conservative treatment. Conclusion: It was suggested that PTIBS was a safe and effective method in the treatment of biliary stricture. There was higher success rate of PTIBS as compared to endoscopic retrograde biliary, approach especially in patients with hilar biliary stricture. If combined with chemotherapy, the survival rate of malignant biliary stricture could be further improved

    Full Text Available We describe the rare instance of concomitant biliary atresia and alpha-1-antitrypsin deficiency and the first documented successful portoenterostomy in this scenario. The potential for dual pathology must be recognized and underscores that prompt diagnosis of biliary atresia, despite concomitant alpha-1-antitrypsin deficiency, is essential to afford potential longstanding native liver function.

    Purpose. - Retrospective study of 23 patients treated with conformal radiotherapy for a locally advanced bile duct carcinoma. Patients and methods. - Eight cases were irradiated after a radical resection (RO), because they were N+; seven after microscopically incomplete resection (R1) ; seven were not resected (R2). A dose of 45 of 50 Gy was delivered, followed by a boost up to 60 Gy in R1 and R2 groups. Concomitant chemotherapy was given in 15 cases. Results.-Late toxicity included a stenosis of the duodenum, and one of the biliary anastomosis. Two patients died from cholangitis, the mechanism of which remains unclear. Five patients are in complete remission, six had a local relapse, four developed a peritoneal carcinosis, and six distant metastases. Actuarial survival rate is 75%, 28% and 7% at 1, 3 and 5 years, respectively (median: 16.5 months). Seven patients are still alive with a 4 to 70 months follow-up. Survival is similar in the 3 small subgroups. The poor local control among RON+ cases might be related to the absence of a boost to the 'tumor bed'. In R1 patients, relapses were mainly distant metastases, where'as local and peritoneal recurrences predominated in R2. Conclusion. - Conformal radio-chemotherapy delivering 60 Gy represents a valuable palliative approach in locally advanced biliary carcinoma. (authors)

    Full Text Available Os AA. chamam a attenção para a raridade deste typo histologico de tumor do estomago e descrevem um caso verificado pela autopsia, em individuo branco, brasileiro, de 67 annos de edade. O tumor localiza-se na pequena curvatura do estomago, sob o aspecto de uma formação crateriforme de 3,5 cms. de diametro e com adherencias ao pancreas. O esophago e o cardia não são de modo algum comprometidos pelo processo. Foram encontradas metastases no coração, no figado, na capsula do pancrea, no pulmão e glandulas suprarenaes. O exame histologico mostra tratar-se de um carcinoma epidermoide, não só no tumor primitivo, como tambem nos fócos metastaticos. As AA. são inclinados a acreditar que o tumor tenha se originado por intermedio de um processo d metaplasia epidermoide da mucosa gastrica.Attention is called by the AA. to the rarity of this histological feature of gastric tumor verified and described, on post mortem examination, in a white Brazilian male, 57 years old. The tumor is located on the lesser curvature of the stomach under the appearance of a crateriform formation, 3.5 cms. in diameter, fast adhering to the pancreas. The esophagus and cardia are not affected by this process. Metastases were found in the heart, liver, capsule of the pancreas, lungs and adrenal glands. The histological examination reveals in te primary tumor and in the metastatic foci a carcinoma of epidermoid type. The AA. are inclined to believe that the tumor might have arisen through an epidermoid-metaplastic process of the gastric mucosa.

    Background: The lung is the most common site of distant metastases from hepatocellular carcinoma. Correct differentiation between metastatic hepatocellular carcinoma of the lung and primary lung cancer is sometimes difficult without biopsy. Purpose: To evaluate the usefulness of measuring the attenuations of pulmonary nodules on early-phase contrast-enhanced computed tomography (CT) for the differentiation of pulmonary metastases from hepatocellular carcinoma and primary lung cancer. Material and Methods: Thirteen patients with pulmonary metastases from hepatocellular carcinoma (nine men, four women; age 53.9±14.2 years, range 16-70 years) and 25 patients with primary lung cancer (14 men, 11 women; age 62.2±9.4 years, range 43-72 years) were retrospectively evaluated. Contrast-enhanced scans were obtained 35 s after commencing intravenous injection of contrast medium. Attenuation values and the size of the pulmonary nodules were measured on contrast-enhanced CT scans. CT and clinical features were analyzed with regard to age, sex, body surface area of the patients, the attenuation values and size of the nodules, and CT machines using univariate analysis (Fisher's exact test for binary data sets and the Mann-Whitney U test for continuous data sets). Multiple linear regression analysis was used to eliminate confounding factors. Results: The mean attenuation value of metastatic pulmonary nodules from hepatocellular carcinoma (75.7±24.9 HU) was higher than that of primary lung cancer nodules (45.8±14.4 HU) (P<0.01). Other variables such as age, sex, body surface area of the patients, CT device, and nodule size were not significant variables on multiple regression analysis. When a cut-off value of 75 HU was applied, the positive predictive value for diagnosing metastatic nodules from hepatocellular carcinoma was 100%. Conclusion: Pending confirmation in a large study, our findings suggest that there is a difference in contrast enhancement between pulmonary

    Purpose: To determine whether findings on CT studies, done 6 weeks after radiotherapy (RT), can predict the likelihood of ultimate control at the primary site in oropharyngeal carcinoma. Methods and Materials: Forty-six patients with oropharyngeal squamous cell carcinoma underwent RT with curative intent. A minimal 2-year clinical follow-up after RT was required. The primary site CT findings were graded for risk of recurrence on a modified 3-point scale as follows: Grade 0, no detectable focal abnormalities; Grade 1, anatomic asymmetry or focal mass 10 mm (2a) or 10 mm at the primary site, the likelihood of local control is high (93%). The study results indicate that CT findings, based on this relatively small series, may not add incremental information beyond that of clinical examination for predicting local control but may be useful as a baseline if imaging surveillance is contemplated

    The biliary and pancreatic secretions have been determined in patients given pelvic or para-aortic irradiation, with a dose of 50 Gy in the former group and between 36 and 40 Gy in the latter. A test meal containing polyethylene glycol (PEG) as reference substance was used. Each sample of the duodenal content was assayed for volume, PEG content, amylase and trypsin activity, pH and biliary secretion. No significant modifications of biliary and pancreatic secretions were demonstrated after irradiation, suggesting that these functions are not involved in the pathogenesis of the malabsorption radiation syndrome.

    The aim of percutaneous transhepatic biliary drainage (PTBD) is to decrease serum bilirubin level and promote liver function in patient with biliary tract disease, especially obstruction by malignant disease. But some patients showed persistent high serum bilirubin level or higher than pre-PTBD level. Percutaneous transhepatic biliary drainage was performed in 341 patients of obstructive jaundice for 5 years form July, 1981 to July, 1986 at department of radiology, Seoul National University Hospital. Follow up check of the serum bilirubin level was possible in 188 patients. Among them the authors analysed 32 patients who showed persistent high serum bilirubin level after PTBD. The results were as follows: 1. The male to female ratio was 3.4:1 and the age ranged from 33 to 75. 2. The causes of obstructive jaundice included 30 malignant diseases and 2 benign diseases. Malignant disease were 16 cases of bile duct carcinoma, 7 cases of pancreatic cancer and 7 cases of metastasis from stomach, colon and uterine cervix. Benign disease were 1 case of common hepatic duct stone and 1 case of intrahepatic duct stones. 3. The most common level of obstruction was trifurcation in 17 cases. 4. The most common indication of PTBD was palliative drainage of obstruction secondary to malignant tumor in 28 cases. 5. Change of serum bilirubin level ratio (post-PTBD level/pre-PTBD level) was 1.28, 1.22, 1.38, 1.51 in serial period of 1-3 days, 4-6 days, 1-2 week 2-3 week after PTBD. 6. Causes of persistent high serum bilirubin level after PTBD were 12 cases of partial drainage of intrahepatic bile, 13 cases of hepatic dysfunction including 9 cases of metastatic nodule, 2 cases of biliary cirrhosis, 2 cases of multiple liver abscess, and 7 cases of poor function of catheter including 4 cases of hemobilia, 1 case of multiple intrahepatic stones, pyobilia and intrahepatic Clonorchis sinensis.

    Obeticholic acid (OCA), a potent farnesoid X receptor agonist, was studied as monotherapy in an international, randomized, double-blind, placebo-controlled phase 2 study in patients with primary biliary cholangitis who were then followed for up to 6 years. The goals of the study were to assess the benefit of OCA in the absence of ursodeoxycholic acid, which is relevant for patients who are intolerant of ursodeoxycholic acid and at higher risk of disease progression. Patients were randomized and dosed with placebo (n = 23), OCA 10 mg (n = 20), or OCA 50 mg (n = 16) given as monotherapy once daily for 3 months (1 randomized patient withdrew prior to dosing). The primary endpoint was the percent change in alkaline phosphatase from baseline to the end of the double-blind phase of the study. Secondary and exploratory endpoints included change from baseline to month 3/early termination in markers of cholestasis, hepatocellular injury, and farnesoid X receptor activation. Efficacy and safety continue to be monitored through an ongoing 6-year open-label extension (N = 28). Alkaline phosphatase was reduced in both OCA groups (median% [Q1, Q3], OCA 10 mg -53.9% [-62.5, -29.3], OCA 50 mg -37.2% [-54.8, -24.6]) compared to placebo (-0.8% [-6.4, 8.7]; P OCA improved many secondary and exploratory endpoints (including γ-glutamyl transpeptidase, alanine aminotransferase, conjugated bilirubin, and immunoglobulin M). Pruritus was the most common adverse event; 15% (OCA 10 mg) and 38% (OCA 50 mg) discontinued due to pruritus. OCA monotherapy significantly improved alkaline phosphatase and other biochemical markers predictive of improved long-term clinical outcomes. Pruritus increased dose-dependently with OCA treatment. Biochemical improvements were observed through 6 years of open-label extension treatment. (Hepatology 2018;67:1890-1902). © 2017 The Authors.

    Primary biliary cirrhosis (PBC) is a disease that affects liver with various severity and progression rates. It is important to diagnose advanced stage of the disease to lower liver-related morbidity and mortality. Since liver biopsy is an invasive method, liver biopsy tends to be replaced by noninvasive methods. In this study, we aim to show the role of aminotransferase to platelet ratio index (APRI) and fibrosis index on the basis of the four factors (FIB-4) scores, laboratory values, and their effectiveness in predicting advanced disease. PBC patients diagnosed pathologically at Numune Education and Research Hospital were included in the study between the years 1995 and 2013. Patients were grouped according to their fibrosis level: group 1 (early stage) included 18 patients with F1 and F2 fibrosis and group 2 (advanced stage) included 22 patients with F3 and F4 fibrosis. APRI and FIB-4 scores, routine laboratory values, and their proportions were compared. The effectiveness of parameters showing advanced stage was further compared. There were statistically significant differences in APRI, FIB-4 scores, and aspartate aminotransferase (AST) levels between the groups with early and advanced stages of disease. Receiver operating curve analysis was used to determine APRI, FIB-4 and AST levels. The most effective parameters for diagnosing an advanced stage were APRI, AST levels, and FIB-4 scores, respectively. In conclusion, APRI and FIB-4 scores can be calculated simply and easily by routine laboratory tests at low cost and also these scores may be a predictor of advanced stage of the disease in PBC. These tests may be reproducible and may be used to monitor disease progression.

    During the last decade patients with concomitant clinical, biochemical, immunoserological, and histological features of both autoimmune hepatitis (AIH) and primary biliary cirrhosis (PBC) were sporadically described, but definite diagnostic criteria and specific serological markers to support the diagnosis of AIH/PBC overlap syndrome (AIH/PBC OS) are still lacking. Clinical, biochemical, and histological features, autoantibody profile, and treatment response of 15 patients with coexistent hepatitic and cholestatic liver damage, all fulfilling strict diagnostic criteria for both AIH and PBC, were compared with those of 120 patients with pure PBC and 120 patients with pure AIH. At diagnosis, the AIH/PBC OS patients' median age was 51 years, similar to that of the PBC patients (52 years, P=NS), but significantly higher than that of the AIH patients (40 years, P=0.04). Anti-dsDNA antibodies were detected in 60% of AIH/PBC OS patients, but only in 4% of PBC patients and 26% of AIH patients (P<0.0001 and 0.01, respectively). Double positivity for antimitochondrial antibodies (AMA) and anti-dsDNA was present in 47% of those with AIH/PBC OS, but only in 2% of the pathological controls (P<0.0001; specificity: 98; 95% confidence interval (CI): 97-99.2; positive likelihood ratio: 28; 95% CI: 9.8-79.4). Combined therapy (ursodeoxycholic acid (UDCA) plus steroids) achieved biochemical response in 77% of AIH/PBC OS patients. Concomitant AMA/anti-dsDNA seropositivity can be considered the serological profile of AIH/PBC OS. The combination of UDCA and steroids is effective in achieving persistent biochemical amelioration in most AIH/PBC OS patients.

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

    Full Text Available The association between primary biliary cirrhosis (PBC and autoimmune hemolytic anemia (AIHA is uncommon; only fourteen such case reports have been described. In this report, three patients who developed AIHA on the basis of PBC underwent successful therapy with corticosteroids and ursodeoxycholic acid (UDCA. Patient 3 was more complicated, suffering from PBC, Evans syndrome, Sjögren syndrome and Klinefelter syndrome simultaneously. This has not previously been reported in the world literature. Review of all fifteen cases showed that there is a prominent occurrence sequence that AIHA might take place on the basis of PBC. With sufficient doses of corticosteroids or immunosuppressant therapy, besides hemolysis under effective control, liver function also improved. According to the criteria of secondary AIHA, we may call them PBC-related AIHA. Thus, patients with PBC with serum bilirubin levels rising suddenly should undergo screening for associated hemolysis. Recommended treatment for PBC-related AIHA includes sufficient doses of corticosteroids to control the hemolysis in the acute phase, and immunosuppressant or adequate dose of UDCA to maintain therapy. These case reports have been increasing in recent years, so further reserch is needed to illustrate the incidence and natural courses of these two organ-specific autoimmune diseases.

    Recent genome-wide association studies suggest that genetic factors contribute to primary biliary cirrhosis (PBC) susceptibility. Although several reports have demonstrated that the interleukin (IL) 12 signaling pathway is involved in PBC pathogenesis, its precise genetic factors have not been fully clarified. Here, we performed an association analysis between IL12A, IL12RB, and signal transducer and activator of transcription 4 (STAT4) genetic variations and susceptibility to PBC. Single nucleotide polymorphisms (SNPs) were genotyped in 395 PBC patients and 458 healthy subjects of Japanese ethnicity and evaluated for associations with PBC susceptibility, anti-nuclear antibody (ANA) status, and anti-mitochondrial antibody (AMA) status. We detected significant associations with PBC susceptibility for several STAT4 SNPs (rs10168266; P = 9.4 × 10(-3), rs11889341; P = 1.2 × 10(-3), rs7574865; P = 4.0 × 10(-4), rs8179673; P = 2.0 × 10(-4), and rs10181656; P = 4.2 × 10(-5)). Three risk alleles (rs7574865; P = 0.040, rs8179673; P = 0.032, and rs10181656; P = 0.031) were associated with ANA status, but not with AMA positivity. Our findings confirm that STAT4 is involved in PBC susceptibility and may play a role in ANA status in the Japanese population.

    Most references in the literature on interventional radiology of the biliary tract refer to the treatment of cancer; only occasionally are benign conditions mentioned. An updated list of radiosurgical instruments on the market in Italy is presented. The operating technique from the preparation of the patient to the performance of percutaneous transhepatic cholangiography (PTC), biliary drainage, transhepatic bilioplasty, percutaneous extraction and chemical cholelitholisis of biliary calculi and drainage of biliary collections is then described. A personal series is then presented. It consist of 93 patients in whom one or more of the following conditions were diagnosed: exclusively intrahepatic calculosis (3 cases), calculosis of the common bile duct (23 percutaneous treatments), empyema of the gallbladder (6 cases), suppurating cholangitis (46 cases), sclerotic or inflammatory stenosis (16 cases), biliary collections (14 cases). Results are reported and commented on

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

    Full Text Available Primary Squamous Cell Carcinoma in the kidney is a rare malignant neoplasm associated with nephrolithiasis, typically monobacterial pyonephrosis and rarely Xanthogranulomatous pyelonephritis. It is an aggressive disease with a poor prognosis mostly due to lack of presenting clinical features like a palpable mass, gross haematuria and pain. We report a case presenting with renal calculus and pyonephrosis managed initially with percutaneous nephrostomy followed by nephrectomy due to complete loss of renal function. Histopathological evaluation revealed poorly differentiated squamous cell carcinoma which is managed by chemotherapy, although initially beneficial, patients later develop disseminated metastatic disease which holds a poor prognosis.

    BACKGROUND: The precision of current prognostic models in primary biliary cirrhosis (PBC) is rather low, partly because they are based on data from just one time during the course of the disease. The aim of this study was to design a new, more precise prognostic model by incorporating follow......-up data in the development of the model. METHODS: We have performed Cox regression analyses with time-dependent variables in 237 PBC patients followed up regularly for up to 11 years. The validity of the obtained models was tested by comparing predicted and observed survival in 147 independent PBC...... patients followed for up to 6 years. RESULTS: In the obtained model the following time-dependent variables independently indicated a poor prognosis: high bilirubin, low albumin, ascites, gastrointestinal bleeding, and old age. When including histological variables, cirrhosis, central cholestasis, and low...

    Early diagnosis and accurate staging of carcinomas of the gallbladder and the bile ducts are helpful in improving the prognosis. Ultrasonography (US), a useful initial modality when exploring the background of jaundice or non-specific gastrointestinal complaints, sensitively reveals bile duct obstruction in particular. In unclear cases, or if US suggests a resectable biliary malignancy, computed tomography (CT), magnetic resonance imaging (MRI) with magnetic resonance cholangiography (MRC) and/or traditional cholangiography often provide additional information, and imaging-guided fine-needle biopsy or an endoscopic brush sample may verify the malignant nature of the tumor. Complementary modalities are usually needed for accurate staging, and traditional cholangiography is often performed for therapeutic purposes as well. Comparative studies of MRI with MRC and multidetector CT in biliary cancers would be welcome.

    Endoscopic retrograde biliary drainage by means of transtumoral endoprostheses is an effective technique for pallliative decompression of malignant biliary obstruction. However, serial follow-up is required for an early detection of eventual long-term complications. In the present study 37 patients with malignant biliary obstruction, trated by endoscopic insertion of one or more biliary stents, were prospectively evaluated by sonography, with serial clinical and US examinations up to 10 months. In this experience, sonography could correctly identify both the endoprostheses and their location in the biliary tract. Most important, sonography has proved to be a sensitive method to detect possible stent dysfunctions, besides providing with information about the prograssion of the underlying malignancy. 19 refs.

    Andrew Y Lee

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

    Merkel cell carcinoma is a rare and aggressive neuroendocrine tumor that commonly arises in the skin. It is rare for it to occur in the testes. There are only seven cases of testicular Merkel cell carcinoma reported in the literature. A 66-year-old Maori man presented to our hospital with left testicular swelling. His alpha-fetoprotein and beta-human chorionic gonadotrophin levels were within normal limits. His lactate dehydrogenase concentration was elevated to 267 U/L. Ultrasound imaging confirmed a large testicular mass, and he underwent left orchiectomy. His histological examination revealed a neuroendocrine tumor with an immunostaining pattern suggesting Merkel cell carcinoma. He presented to our hospital again 3 months later with right testicular swelling that was confirmed on ultrasound sonography to be a tumor. He underwent a right orchiectomy, and his histological examination revealed metastatic Merkel cell carcinoma. A primary lesion was not identified, and computed tomographic imaging did not reveal spread to other organs. He received six cycles of adjuvant carboplatin and etoposide chemotherapy and remained disease-free 18 months after completion of chemotherapy. Given the paucity of studies, standard adjuvant treatment for testicular Merkel cell carcinoma remains uncertain, although platinum-based chemotherapy seems to be an appropriate option.

    The results of treatment of 84 patients for chronic pancreatitis with the biliary hypertension signs were depicted. In 83 patients operative interventions were performed, and in 1--positive results were achieved after pancreatic cyst puncture under ultrasonographic control. In 51 patients the conduction of Frey operation have permitted to achieve a lower pressure inside biliary system, in 25--the additional procedures were applied for a biliary hypertension elimination. In 20 patients a method of pressure measurement in biliary system was used.

    Hilar cholangiocarcinoma is a tumor of the extrahepatic bile duct involving the left main hepatic duct, the right main hepatic duct, or their confluence. Biliary drainage in hilar cholangiocarcinoma is sometimes clinically challenging because of complexities associated with the level of biliary obstruction. This may result in some adverse events, especially acute cholangitis. Hence the decision on the indication and methods of biliary drainage in patients with hilar cholangiocarcinoma should be carefully evaluated. This review focuses on the optimal method and duration of preoperative biliary drainage (PBD) in resectable hilar cholangiocarcinoma. Under certain special indications such as right lobectomy for Bismuth type IIIA or IV hilar cholangiocarcinoma, or preoperative portal vein embolization with chemoradiation therapy, PBD should be strongly recommended. Generally, selective biliary drainage is enough before surgery, however, in the cases of development of cholangitis after unilateral drainage or slow resolving hyperbilirubinemia, total biliary drainage may be considered. Although the optimal preoperative bilirubin level is still a matter of debate, the shortest possible duration of PBD is recommended. Endoscopic nasobiliary drainage seems to be the most appropriate method of PBD in terms of minimizing the risks of tract seeding and inflammatory reactions. PMID:24634710

    Full Text Available Abstract Merkel cell carcinoma (MCC is a relatively rare, polyomavirus associated, primary neuroendocrine carcinoma of the skin which is usually arising from dermal skin layers. However, the origin of MCC in the subcutaneous tissue is debatable. We report a 58-yearold female patient with an oedematous mass on her left groin that was firm in consistency and had no discoloration or other visible abnormality of the overlying skin. On histology and immunohistology the tumour was consistent with the diagnosis of MCC showing a predominant subcutanous growth pattern. Pelvic magnetic resonance tomography revealed a tumour conglomerate reaching from the subcutis of the left groin to the left paraaortal and parailiacal region indicating widespread lymphogenic metastisation. Despite complete medical work-up no other MCC primary could be detected. In conclusion, predominant subcutaneous growth pattern as well as tumour localization in the groin are uncommon features of MCC. MCC showing the aforementioned features may be associated with significant delay of diagnosis and therefore represents an unfavourable prognostic factor.

    Full Text Available Unsatisfactory effects of treatment of laryngeal carcinoma patients stimulate the clinicians as well as researchers to develop new more effective treatment models and to find new reliable prognostic factors. The aim of the present study was the evaluation of the use of primary cell cultures of the laryngeal carcinoma and laser scanning cytometry (LSC in the assessment of tumor reactivity to cisplatinum. Nineteen primary cultures of laryngeal carcinoma cells established from fragments of laryngeal carcinoma infiltrations were cultured with or without cisplatin, stained with monoclonal antibodies against P53 and BCL-2 proteins and analyzed by LSC. Cisplatin added to the culture medium leads to the significant increase of P53 expression and decrease of BCL-2 expression. Moreover, changes of P53 and BCL-2 expressions were significantly correlated. Our findings of apoptosis regulatory mechanisms could be useful in patient qualification for the chemotherapeutic follow-up treatment.

He was found to have an elevated total bilirubin of 10 mg/dL, direct bilirubin of 7 mg/dL, alkaline phosphatase of 405 U/L, and lipase of 370 U/L. Imaging showed cholelithiasis with likely intra- and extrahepatic biliary duct dilatation. The patient underwent placement of a biliary drain with clinical improvement. Additional imaging was requested prior to endoscopic retrograde cholangiopancreatography (ERCP, but magnetic resonance cholangiopancreatography (MRCP was unavailable due to metallic implants. Interventional radiology performed a cholangiogram using the biliary drain which confirmed biliary obstruction. ERCP was then performed, with significant biliary sludge found and two stents placed.

    Primary surgery is the preferred treatment of T1-T4a sinonasal squamous cell carcinoma (SNSCC). Patients with SNSCC in the National Cancer Data Base (NCDB) were analyzed. Factors that contributed to selecting primary surgical treatment were examined. Overall survival (OS) in surgical patients was analyzed. Four-thousand seven hundred and seventy patients with SNSCC were included. In T1-T4a tumors, lymph node metastases, maxillary sinus location, and treatment at high-volume centers were associated with selecting primary surgery. When primary surgery was utilized, tumor factors and positive margin guided worse OS. Adjuvant therapy improved OS in positive margin resection and advanced T stage cases. Tumor and non-tumor factors are associated with selecting surgery for the treatment of SNSCC. When surgery is selected, tumor factors drive OS. Negative margin resection should be the goal of a primary surgical approach. When a positive margin resection ensues, adjuvant therapy may improve OS. © 2017 Wiley Periodicals, Inc.

    The Frey procedure has become the standard operative treatment in chronic painful pancreatitis. Biliary diversion could be combined when associated with common bile duct obstruction. The aim of the present study was to evaluate the impact of the type of biliary diversion combined with the Frey procedure on late morbidity. The data from consecutive patients undergoing the Frey procedure and having a minimum follow-up of 2 years were extracted from a maintained prospective database. The mean endpoint was the rate of secondary biliary stricture after the Frey procedure combined with biliary diversion (bilioenteric anastomosis or common bile duct reinsertion in the resection cavity). Between 2006 and 2013, 55 consecutive patients underwent the Frey procedure. Twenty-nine patients had common bile duct obstruction (52.7%). The technique of biliary diversion resulted in bilioenteric anastomosis in 19 patients (65.5%) and common bile duct reinsertion in 10 patients (34.5%). Preoperative characteristics and early surgical outcomes were comparable. Pain control was similar. There was significantly more secondary biliary stricture after common bile duct reinsertion than after bilioenteric anastomosis (60% vs 11%, P = .008). Combined bilioenteric anastomosis during the Frey procedure is an efficient technique for treating common bile duct obstruction that complicates chronic painful pancreatitis. Bilioenteric anastomosis was associated with less secondary biliary stricture than common bile duct reinsertion in the pancreatic resection cavity. Copyright © 2016 Elsevier Inc.

  16. The pathogenesis of primary biliary cirrhosis Patogénesis en cirrosis biliar primaria

    Directory of Open Access Journals (Sweden)

    J. A. Solís Herruzo

    2009-06-01

    Full Text Available Primary biliary cirrhosis (PBC would develop when the immune system comes across a microorganism with proteins similar to those in the piruvate dehydrogenase complex E2 (PDC-E2, or a neoantigen resulting from a xenobiotic-modified autoantigen. This would lead to an innate immune response where TLRs would play a pivotal mediating role, which would give rise to a local microenvironment favoring an adaptive immune response. Such response would be particularly strong in individuals with selected genetic characteristics. The genetic characteristics underlying this predisposition remain unknown, but they likely entail small numbers of scarcely-active regulatory T cells. The AE2 anion exchanger, which is deficient in patients with PBC, may reduce the number and activity of regulatory T cells. NK cells are also pivotal in the preparation of an adaptive response, as they release a number of cytokines and chemokines that favor and recruit antigen-presenting cells to activate B and T cells - CD4+ Th1 and CD8+. An activation of the former would increase the production of IgM and anti-mitochondrial IgG and IgA antibodies against PDC-E2. An activation of CD8+ cells, also sensitive to PDC-2 as aberrantly expressed on the surface of BECs and SECs, would result in apoptosis for these epithelial cells, and in small bile-duct destruction. Immune response is likely inadequately suppressed because of the small numbers of scarcely-active regulatory T cells, the latter resulting from low genetic expression and activity of the AE2 transporter.

  17. Innate immunity drives the initiation of a murine model of primary biliary cirrhosis.

    Directory of Open Access Journals (Sweden)

    Full Text Available Invariant natural killer T (iNKT cells play complex roles in bridging innate and adaptive immunity by engaging with glycolipid antigens presented by CD1d. Our earlier work suggested that iNKT cells were involved in the initiation of the original loss of tolerance in primary biliary cirrhosis (PBC. To address this issue in more detail and, in particular, to focus on whether iNKT cells activated by a Th2-biasing agonist (2s,3s,4r-1-O-(α-D-galactopyranosyl-N-tetracosanoyl-2-amino-1,3,4-nonanetriol (OCH, can influence the development of PBC in a xenobiotic-induced PBC murine model. Groups of mice were treated with either OCH or, as a control, α-galactosylceramide (α-GalCer and thence serially followed for cytokine production, markers of T cell activation, liver histopathology and anti-mitochondrial antibody responses. Further, additional groups of CD1d deleted mice were similarly studied. Our data indicate that administration of OCH has a dramatic influence with exacerbation of portal inflammation and hepatic fibrosis similar to mice treated with α-GalCer. Further, iNKT cell deficient CD1d knockout mice have decreased inflammatory portal cell infiltrates and reduced anti-mitochondrial antibody responses. We submit that activation of iNKT cells can occur via overlapping and/or promiscuous pathways and highlight the critical role of innate immunity in the natural history of autoimmune cholangitis. These data have implications for humans with PBC and emphasize that therapeutic strategies must focus not only on suppressing adaptive responses, but also innate immunity.

    Transitional cell carcinoma (TCC) of the female urethra is a rare urological malignancy, and intracranial metastasis of this cancer has not yet been reported in the literature. This review is intended to present a case of multiple intracranial metastasis in a female patient with a remote history of primary urethral TCC. A 49-year-old woman, presented with a prolapsed mass in urethral orifice that was diagnosed as primary urethral TCC with distant lung and multiple bone metastases. The patient subsequently underwent chemotherapy under various regimens. A year later, the patient developed headache and vomiting which as was found to be due to multiple intracranial metastasis. The patient underwent surgical resection of the largest lesion located on the cerebellum, and consecutively gamma knife radiosurgery was performed for other small-sized lesions. Pathological examination of the resected mass revealed a metastatic carcinoma from a known urethral TCC. Serial work-up of systemic metastasis revealed concomitant aggravation of lung, spleen, and liver metastasis. The patient died of lung complication 2 months after the diagnosis of brain metastasis. To the best of our knowledge, this is the first reported case of cerebral metastasis from primary urethral TCC, with pathological confirmation. As shown in intracranial metastasis of other urinary tract carcinoma, this case occurred in the setting of uncontrolled systemic disease and led to dismal prognosis in spite of aggressive interventional modalities

    The purpose of this study was to find out what clinicopathologic or immunohistochemical parameter that may affect FDG uptake of primary tumor in PET/CT scan of the gastric carcinoma patient. Eighty-nine patients with stomach cancer who underwent pre-operative FDG PET/CT scans were included. In cases with perceptible FDG uptake in primary tumor, the maximum standardized uptake value (SUVmax) was calculated. The clinicopathologic results such as depth of invasion (T stage), tumor size, lymph node metastasis, tumor differentiation and Lauren's classification and immunohistochemical markers such as Ki-67 index, expression of p53, EGFR, Cathepsin D, c-erb-B2 and COX-2 were reviewed. Nineteen out of 89 gastric carcinomas showed imperceptible FDG uptake on PET/CT images. In cases with perceptible FDG uptake in primary tumor, SUVmax was significantly higher in T2, T3 and T4 tumors than T1 tumors (5.8±3.1 vs. 3.7±2.1, p=0.002). SUVmax of large tumors (above or equal to 3 cm) was also significantly higher than SUVmax of small ones (less than 3 cm) (5.7±3.2 vs. 3.7±2.0, p=0.002). The intestinal types of gastric carcinomas according to Lauren showed higher FDG uptake compared to the non-intestinal types (5.4±2.8 vs. 3.7±1.3, p=0.003). SUVmax between p53 positive group and negative group was significantly different (6.0±2.8 vs. 4.4±3.0, p=0.035). No significant difference was found in presence of LN metastasis, tumor differentiation, Ki-67 index, and expression of EGFR, Cathepsin D, c-erb-B2 and COX-2. T stage of gastric carcinoma influenced the detectability of gastric cancer on FDG PET/CT scan. When gastric carcinoma was perceptible on PET/CT scan, T stage, size of primary tumor, Lauren's classification and p53 expression were related to degree of FDG uptake in primary tumor

    Virtually all primary peritoneal carcinomas (PPCs) are of serous papillary type. We report an unusual histologic type of PPC composed of anaplastic giant cells, which exhibited an aggressive clinical course. A 72-year-old woman presented with lower abdominal pain. Computed tomography showed a diffuse omental thickening. The patient underwent an exploratory laparotomy with omentectomy, total hysterectomy, bilateral salpingo-oophorectomy, and appendectomy. Pathologic examination revealed extensive omental replacement by tumor but only superficial surface cortical involvement of both ovaries, a disease distribution consistent with a typical müllerian-derived PPC. However, this neoplasm was composed of diffuse anaplastic tumor giant cells, rather than serous carcinoma, which is the usual histologic type encountered in PPC. The patient died within 1 month after surgery. We report this unusual histologic variant of PPC to raise awareness that anaplastic giant cell carcinoma may arise in the pelvic peritoneum as a primary tumor.

    Full Text Available We report a 24-year-old woman presenting with a relapsed soy-bean-size tender mass at the junction of the soft and hard palate and a history of palatine tumor of small cell carcinoma. Reexcision surgery was performed and histopathological features were consistent. The patient was treated with six cycles of chemotherapy consisting of etoposide and cisplatin. After one year, the patient developed bone metastases and Cushing's syndrome, and successfully recovered with subsequent chemotherapy with irinotecan and cisplatin plus radiotherapy. There was no evidence of recurrence or metastasis for more than three years. Small cell carcinoma originating in the head and neck region has been reported to be highly aggressive and has a poor prognosis. This is the first case report of a patient with relapsed primary small cell carcinoma of the palate and successfully treated with second-line chemotherapy and local radiotherapy.

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

    The development of accessory breast tissue, which is found anywhere along the milk line, is attributed to the failure of milk line remnants to regress during embryogenesis. Primary tumors may arise from any ectopic breast tissue. Accessory breast cancer occurring concurrently with primary invasive breast cancer is extremely rare. Two such cases were reported in this article. One was a 43-year-old Chinese female who exhibited bilateral breast cancer (invasive ductal carcinoma, not otherwise specified, IDC-NOS) and an accessory breast carcinoma (IDC-NOS) incidentally identified in her left axilla. The ectopic breast tissue in her right axilla presented with adenosis. The patient was surgically treated, followed by postoperative docetaxel epirubicin (TE) chemotherapy. The second case was a 53-year-old Chinese female with bilateral breast cancer (apocrine carcinoma) accompanied by an accessory breast carcinoma (IDC-NOS) in her right axilla that was also incidentally identified. The patient was surgically treated after three doses of cyclophosphamide epirubicin docetaxel (CET) neoadjuvant chemotherapy, followed by adjuvant chemotherapy of the same regimen

    Liver surgery in perihilar cholangiocarcinoma (PHC) is associated with high postoperative morbidity because the tumor typically causes biliary obstruction. Preoperative biliary drainage is used to create a safer environment prior to liver surgery, but biliary drainage may be harmful when severe drainage-related complications deteriorate the patients' condition or increase the risk of postoperative morbidity. Biliary drainage can cause cholangitis/cholecystitis, pancreatitis, hemorrhage, portal vein thrombosis, bowel wall perforation, or dehydration. Two methods of preoperative biliary drainage are mostly applied: endoscopic biliary drainage, which is currently used in most regional centers before referring patients for surgical treatment, and percutaneous transhepatic biliary drainage. Both methods are associated with severe drainage-related complications, but two small retrospective series found a lower incidence in the number of preoperative complications after percutaneous drainage compared to endoscopic drainage (18-25% versus 38-60%, respectively). The present study randomizes patients with potentially resectable PHC and biliary obstruction between preoperative endoscopic or percutaneous transhepatic biliary drainage. The study is a multi-center trial with an "all-comers" design, randomizing patients between endoscopic or percutaneous transhepatic biliary drainage. All patients selected to potentially undergo a major liver resection for presumed PHC are eligible for inclusion in the study provided that the biliary system in the future liver remnant is obstructed (even if they underwent previous inadequate endoscopic drainage). Primary outcome measure is the total number of severe preoperative complications between randomization and exploratory laparotomy. The study is designed to detect superiority of percutaneous drainage: a provisional sample size of 106 patients is required to detect a relative decrease of 50% in the number of severe preoperative

    Primary biliary cirrhosis (PBC) is generally a slowly progressive disease that may lead to cirrhosis and liver failure. However, patients with PBC often suffer from a variety of symptoms long before the development of cirrhosis that include issues of daily living that have an impact on their work environment and their individual quality of life. We therefore examined multiple parameters by taking advantage of the database of our cohort of 1032 patients with PBC and 1041 matched controls. The data were obtained from patients from 23 tertiary referral centers throughout the United States and from rigorously matched controls by age, sex, ethnicity, and random-digit dialing. The data showed that patients with PBC were more likely than controls to have significant articular symptoms, a reduced ability to perform household chores, and the need for help with routine activities. Patients with PBC rated their overall activity similar or superior to that of controls; however, more of them reported limitations in their ability to carry out activities at work or at home and difficulties in everyday activities. PBC cases also more frequently reported limitations in participating in certain sports or exercises and pursuing various hobbies; however, they did not report significant limitations in social activities. In a multivariable analysis, household income, a diagnosis of systemic lupus erythematosus, limitations in work activities, a reduction in work secondary to disability, and church attendance were independently increased in PBC cases with respect to controls. Conclusion Our data indicate that the quality of life of patients with PBC in the United States is generally well preserved. Nevertheless, patients with PBC suffer significantly more than controls from a variety of symptoms that are beyond the immediate impact of liver failure and affect their lifestyle, personal relationships, and work activities.

    Anti nuclear (ANA) immunomorphological patterns such as multiple nuclear dots (MND) and rim-like/membranous (RL/M) are considered highly specific but little sensitive for primary biliary cirrhosis (PBC) diagnosis. To evaluate frequency and clinical significance of MND and RL/M in PBC patients when investigated at the level of immunoglobulin G isotypes. MND and RL/M pattern have been tested in 141 PBC sera and 230 pathological controls using HEp-2 cells as substrate and anti- total IgG and individual IgG subclasses (IgG1, IgG2, IgG3, IgG4) as specific antisera. One hundred and fourteen of 141 (80%) PBC patients had RL/M or MND pattern when IgG subclasses were used as revealing reagents (vs. 34% when anti total IgG were used, p < 0.0001). The prevalent isotype was IgG1 for RL/M, and IgG2 for MND pattern. None of controls was positive. No clinical differences in terms of severity and outcome of disease have been observed in PBC patients positive for MND and RL/M when investigated with IgG isotypes. The research for RL/M and MND pattern at level of IgG isotype determines a wide gain in terms of sensitivity without a loss of specificity. In Italian PBC patients MND and RL/M pattern did not seem to characterize any subgroup of patients with a poorer prognosis.

    Full Text Available Background. Breast carcinoma is the most common malignancy in women worldwide. It is most commonly associated with metastases to the liver, lung, bone, and the brain. Invasive lobular carcinoma is a less common pathology with slightly higher metastases to the upper gastrointestinal tract. Invasive lobular carcinoma metastasis to the gallbladder is extremely rare. Method. In this paper we are presenting a case of a 67-year-old female with metastases of invasive lobular breast cancer to the gallbladder six years after her therapy. Conclusion. This case clearly signifies the nature of the micrometastatic foci of the invasive lobular carcinoma even many years after a successful treatment.

    Full Text Available ObjectiveTo investigate the risk factors for non-anastomotic biliary stricture (NABS following liver transplantation. MethodsA retrospective analysis was performed on 175 patients who underwent liver transplantation from January 2004 to December 2010 to analyze the risk factors for NABS, which included sex, age, primary disease, blood type, T-tube placement, acute rejection, biliary tract infection, cytomegalovirus infection, Child-Pugh score, cold ischemia time, warm ischemia time, duration of anhepatic phase, and mean hepatic artery blood flow within one week after operation. These patients were divided into early group, who underwent operation from January 2004 to December 2006, and late group, who underwent operation from January 2007 to December 2010; each group was further divided into two subgroups according to whether they developed NABS. The risk factors for NABS were determined by univariate and multivariate logistic regression analyses. ResultsThe univariate logistic regression analysis showed that the risk factors for NABS were biliary tract infection, T-tube placement, and acute rejection in the early group (P<0.05 and that acute rejection was the risk factor in the late group (P=0003. The multivariate logistic regression analysis showed that acute rejection was significantly associated with NABS in the early group (P=0.014. ConclusionThe risk factors for NABS following liver transplantation from January 2004 to December 2006; biliary tract infection and T-tube placement could be prevented by perioperative interventions, thus reducing the incidence of NABS. The incidence of acute rejection was reduced from January 2007 to December 2010, but it was still significantly associated with NABS.

    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.

    Numerous clinical trials to improve the success rate of biliary access in difficult biliary cannulation (DBC) during ERCP have been reported. However, standard guidelines or sequential protocol analysis according to different methods are limited in place. We planned to investigate a sequential protocol to facilitate selective biliary access for DBC during ERCP. This prospective clinical study enrolled 711 patients with naïve papillae at a tertiary referral center. If wire-guided cannulation was deemed to have failed due to the DBC criteria, then according to the cannulation algorithm early precut fistulotomy (EPF; cannulation time > 5 min, papillary contacts > 5 times, or hook-nose-shaped papilla), double-guidewire cannulation (DGC; unintentional pancreatic duct cannulation ≥ 3 times), and precut after placement of a pancreatic stent (PPS; if DGC was difficult or failed) were performed sequentially. The main outcome measurements were the technical success, procedure outcomes, and complications. Initially, a total of 140 (19.7%) patients with DBC underwent EPF (n = 71) and DGC (n = 69). Then, in DGC group 36 patients switched to PPS due to difficulty criteria. The successful biliary cannulation rate was 97.1% (136/140; 94.4% [67/71] with EPF, 47.8% [33/69] with DGC, and 100% [36/36] with PPS; P EPF, 314.8 (65.2) seconds in DGC, and 706.0 (469.4) seconds in PPS (P EPF, DGC, and PPS may be safe and feasible for DBC. The use of EPF in selected DBC criteria, DGC in unintentional pancreatic duct cannulations, and PPS in failed or difficult DGC may facilitate successful biliary cannulation.

    In conclusion, primary non-urachal enteric-type adenocarcinoma of the urinary bladder is morphologically and immunophenotypically similar – if not identical – to colonic adenocarcinoma. The frequent association of enteric carcinomas of the urinary bladder with intestinal metaplasia and/or colonic-type adenomas with dysplasia suggests possible carcinogenetic pathways similar to that observed in colorectal carcinomas.

    Full Text Available Abstract: We present a rare case of extraovarian primary peritoneal carcinoma in 65-year-old female with a history of total abdominal hysterectomy and bilateral salpingo-oophorectomy for larger symptomatic leiomyoma 13 years ago. In October 2005 the patient had abdominal swelling, ascites with positive cytology peritonal adenocarcinoma and significantly elevated serum Ca-125 was 500 U/ml. Clinical examinations were performed, but could not identify a unique origin of disease. Background: Aproximatly 3.2 % to 21 % of extraovarian primary peritoneal carcinoma patients have a history bilateral oophorectomy for benign disease or prophylaxis – family history of ovar- ian carcinoma.1 Patients and methods: A 65-year old woman with a history of total abdominal hysterectomy and bileteral salpin- go-oophorectomy was operated for larger symptomatic leiomyoma 13 years ago. In Octobre 2005 the patient had abdominal swelling, ascites with positive cytology peritonal adeno- carcinoma and significantly elevated serum Ca-125 was 500 U/ml. Radiologic imaging, gastroscopy, colonoscopy, mammography were performed, but couldn`t identify a unique origin of disease. Patient was treated for two years at the Oncology Institute Ljubljana. Significantly elevated serum Ca-125 and citology with immunohistochemical analysis pre- sented correct diagnosis of extraovarian primary peritoneal carcinoma. The patient was treated with combination systemic chemotherapy (Paclitaxel and Carboplatin with initial good response. In year 2006 and 2007 because of the progression of disease, the treatment was repeated with adjuvant chemotherapy. Conclusions: Look like in other similar cases we have confirmed our disease with three cytologic punction procedures, with significant elevated valves of Ca-125 and with several other directed proce- dures.1–3 Our patient has survived the characteristic critical period for this form of cancer of 7 to 27.8 months because of well orientated

    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.

    In patients with inoperable malignant biliary obstruction, percutaneous transhepatic biliary drainage (PTBD) has been the method of choice for palliative treatment. All patients except three had undergone PTBD, and the stents were placed 5-7 days after the initial drainage procedure. Three patients underwent stent placement on the same day of PTBD. External drainage catheter is converted to various types of tube endoprostheses with associated physiologic and psychologic benefits. Tube stents, however, have some problems such as migration, occlusion, and traumatic implantation procedure. We report our experiences and clinical results of percutaneous placement of metallic stents in 40 patients with malignant biliary obstruction

    Endoscopic retrograde cholangiopancreatography (ERCP) is a diagnostic method and treatment approach for biliary diseases. However, biliary cannulation can be difficult in some cases. We performed ERCP in a 97-year-old woman with abdominal pain resulting from acute cholangitis caused by choledocholithiasis and observed difficult biliary cannulation. Eventually, the patient was successfully treated with the rendezvous technique. We could not cannulate the biliary duct during ERCP twice. Therefore, we placed a percutaneous transhepatic gallbladder drainage (PTGBD) tube without intrahepatic dilation. The rendezvous technique was performed using the PTGBD tube. The patient did not experience pancreatitis or perforation.

    The major histocompatibility complex class II alleles at the HLA-DPB1 locus were investigated in 32 German Caucasoid patients with primary biliary cirrhosis (PBC) and compared with those from 47 normal control patients using molecular genotyping techniques. The second exon of the HLA-DPB1 gene was amplified by polymerase chain reaction (PCR) and hybridized with 25 sequence-specific oligonucleotides (SSOs) to assign the HLA-DPB1 alleles on the basis of known sequence variations, according to the protocols of the Eleventh International Histocompatibility Workshop. A strong association of PBC was found with the allele HLA-DPB1*0301. The allele HLA DPB1*0301 was present in 50% (16 of 32) of the patients with PBC compared with 13% (6 of 47) of normal controls (P corrected < .015), whereas the other HLA-DPB1 alleles showed no significant differences in both groups. The relative risk (RR) estimate for the allele HLA-DPB1*0301 was 6.8 (95% confidence limits: 2.27 to 20.57). In summary, this study clearly demonstrates an association of PBC with the HLA-DPB1*0301 allele in German Caucasoids and may add new data to the immunogenetic background of PBC, suggesting a contribution of the HLA-DPB1 gene to the genetic susceptibility of the disease.

    Full Text Available Primary squamous cell carcinoma of the thyroid is an extremely rare neoplasm with aggressive behavior. Until date, only around 60 cases have been reported in the literature. Primary treatment of the patient is radical surgery. With optimum treatment survival is not more than 6 months in this aggressive malignancy. However in our patient surgery it was not possible because of unresectability of the mass due to encroachment of major vessels. Hence, we have delivered radiotherapy alone, with which effective palliation could be achieved and patient is leading a good quality-of-life for last 1 year.

  10. An Update on Endoscopic Management of Post-Liver Transplant Biliary Complications

    2017-09-01

    Full Text Available Biliary complications are the most common post-liver transplant (LT complications with an incidence of 15%–45%. Furthermore, such complications are reported more frequently in patients who undergo a living-donor LT compared to a deceased-donor LT. Most post-LT biliary complications involve biliary strictures, bile leakage, and biliary stones, although many rarer events, such as hemobilia and foreign bodies, contribute to a long list of related conditions. Endoscopic treatment of post-LT biliary complications has evolved rapidly, with new and effective tools improving both outcomes and success rates; in fact, the latter now consistently reach up to 80%. In this regard, conventional endoscopic retrograde cholangiopancreatography remains the preferred initial treatment. However, percutaneous transhepatic cholangioscopy is now central to the management of endoscopy-resistant cases involving complex hilar or multiple strictures with associated stones. Many additional endoscopic tools and techniques—such as the rendezvous method, magnetic compression anastomosis , and peroral cholangioscopy—combined with modified biliary stents have significantly improved the success rate of endoscopic management. Here, we review the current status of endoscopic treatment of post-LT biliary complications and discuss conventional as well as the aforementioned new tools and techniques.

    Background Primary mucinous carcinoma of the skin (PMCS) is a rare malignant tumor deriving from the sweat glands. It is typically located on the head and is often mistaken for a metastasis from a more common primary tumor of the breast or gastrointestinal tract. We present the first population......-based study of PMCS. Materials and methods Data on PMCS was obtained from the Danish Cancer Registry, which has recorded incident cases of cancer on a nationwide basis since 1943. We extracted all patients diagnosed 1978-2003 with PMCS. Results Fifteen cases of PMCS have been registered during the study...... or PMCS related deaths were reported. Conclusion PMCS is a rare, slow-growing tumor which rarely metastasizes and is associated with low mortality. The age-standardized incidence rate, based on data from a population-based cancer registry of high quality and validity, is less than 0.1 per million. However...

    Benign biliary strictures comprise a heterogeneous group of diseases. The most common strictures amenable to endoscopic treatment are post-cholecystectomy, post-liver transplantation, related to primary sclerosing cholangitis and to chronic pancreatitis. Endoscopic treatment of benign biliary strictures is widely used as first line therapy, since it is effective, safe, noninvasive and repeatable. Endoscopic techniques currently used are dilation, multiple plastic stents insertion and fully covered self-expandable metal stents. The main indication for dilation alone is primary sclerosing cholangitis related strictures. In the vast majority of the remaining cases, temporary placement of multiple plastic stents with/without dilation is considered the treatment of choice. Although this approach is effective, it requires multiple endoscopic sessions due to the short duration of stent patency. Fully covered self-expandable metal stents appear as a good alternative to plastic stents, since they have an increased radial diameter, longer stent patency, easier insertion technique and similar efficacy. Recent advances in endoscopic technique and various devices have allowed successful treatment in most cases. The development of novel endoscopic techniques and devices is still ongoing.

    2014-03-01

    Full Text Available Acute biliary pancreatitis is one of the major causes of acute pancreatitis.Gallstones, biliary sludge and microlithiasis, especially in pancreatitis without detectable reason, can be the cause of acute pancreatitis. Acute biliary pancreatitis has many controversions in the literature, and its classification and guidelines are being updated very frequently. Atlanta classifications which determine the definitions and guidelines about acute pancreatitis were renewed and published in 2013. It has various clinical aspects, ranging from a mild form which is easily treated, to a severe form that causes complications leading to mortality. The pathogenesis of this disease has not been fully elucidated and several theories have been suggested. New scoring systems and laboratory methods such as proteomics have been suggested for both diagnosis and to predict disease severity, and research on these topics is still in progress. Novel therapeutic approaches with technological developments such as ERCP, ES, MRCP, and EUS are also suggested.

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

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

    Treatment of unresectable malignant hilar biliary stricture (UMHBS) is challenging, especially after failure of repeated transpapillary endoscopic stenting. Endoscopic ultrasonography-guided intrahepatic biliary drainage (EUS-IBD) is a recent technique for intrahepatic biliary decompression, but indications for its use for complex hilar strictures have not been well studied. The aim of this study was to assess the feasibility and safety of EUS-IBD for UMHBS after failed transpapillary re-intervention. Retrospective analysis of all consecutive patients with UMHBS of Bismuth II grade or higher who, between December 2008 and May 2016, underwent EUS-IBD after failed repeated transpapillary interventions. The technical success, clinical success, and complication rates were evaluated. Factors associated with clinical ineffectiveness of EUS-IBD were explored. A total of 30 patients (19 women, median age 66 years [range 52-87]) underwent EUS-IBD for UMHBS during the study period. Hilar biliary stricture morphology was classified as Bismuth II, III, or IV in 5, 13, and 12 patients, respectively. The median number of preceding endoscopic interventions was 4 (range 2-14). EUS-IBD was required because the following procedures failed: duodenal scope insertion (n = 4), accessing the papilla after duodenal stent insertion (n = 5), or achieving desired intrahepatic biliary drainage (n = 21). Technical success with EUS-IBD was achieved in 29 of 30 patients (96.7%) and clinical success was attained in 22 of these 29 (75.9%). Mild peritonitis occurred in three of 30 (10%) and was managed conservatively. Stent dysfunction occurred in 23.3% (7/30). There was no procedure-related mortality. On multivariable analysis, Bismuth IV stricture predicted clinical ineffectiveness (odds ratio = 12.7, 95% CI 1.18-135.4, P = 0.035). EUS-IBD may be a feasible and effective rescue alternative with few major complications after failed transpapillary endoscopic re-intervention in patients

    Full Text Available Primary signet-ring cell carcinoma (SRCC of vermiform appendix is extremely rare; only three cases have been reported in the English literature. An 89-year-old man suddenly presented right lower abdominal pain, and transferred to a hospital, where he was diagnosed with acute appendicitis by physical data, blood data, and CT. He was further transferred to our hospital for emergency operation. Physical examination showed positive abdominal pain, Blunberg sign, and Rosenstein sign. Blood test showed leukocytosis and increased C-reactive protein. An appendectomy was performed. Gross examination during operation showed inflamed appendix, appendiceal adhesion, and acute peritonitis. Gross pathological examination showed no apparent tumor, but the proximal appendix showed wall thickening and luminal occlusion. The appendix was cut into three sections, and was observed under microscopically. Nests of carcinoma cells were seen in the proximal appendix. The carcinoma was composed of SRCC (70% and mucinous carcinoma (30%. The size of carcinoma was 6 × 7 mm. The carcinoma cells invaded into muscular layer. No lymphovascular permeation was seen. The cut margins were negative for carcinoma cells. Immunohistochemically, SRCC cells were positive for cytokeratin (CK AE1/3, CK CAM5.2, CK8, CK18, CK19, CK20, EMA, CEA, CA19-9, p53, Ki-67 (labeling = 30%, CDX2, MUC2, and MUC5AC. They were negative for CK34PE1, CK5/6, CK7, CK14, p63, vimentin, TTF-1, MUC1, MUC 5AC, NSE, synaptophysin, chromogranin, and CD56. No further treatments were performed, because the appendiceal carcinoma was small, the surgical margins were negative and the patient was very old. He was followed up by various imaging modalities. No recurrence or metastasis is found 17 months after the operation.

    To determine whether the relative metabolic activity of pelvic or para-aortic LN compared with that of primary tumor measured by preoperative [{sup 18}F]FDG PET/CT scan has prognostic value in patients with endometrioid endometrial carcinoma. We retrospectively reviewed patients with endometrioid endometrial carcinoma who underwent preoperative [{sup 18}F]FDG PET/CT scans. Prognostic values of PET/CT-derived metabolic variables such as maximum standardized uptake value (SUV) of the primary endometrial carcinoma (SUV{sub Tumor}) and LN (SUV{sub LN}), and the LN-to-endometrial carcinoma SUV ratio (SUV{sub LN} / SUV{sub Tumor}) were assessed. Clinico-pathological data, imaging data, and treatment results were reviewed for 107 eligible patients. Median post-surgical follow-up was 23 months (range, 6-60), and 7 (6.5%) patients experienced recurrence. Regression analysis showed that SUV{sub LN} / SUV{sub Tumor} (P < 0.001), SUV{sub LN} (P = 0.003), International Federation of Gynecology and Obstetrics (FIGO) stage (P = 0.006), and tumor grade (P = 0.011) were risk factors of recurrence. Multivariate regression analysis revealed that FIGO stage (P = 0.034) was the independent risk factor of recurrence. SUV{sub LN} / SUV{sub Tumor} showed significant correlation with FIGO stage (P < 0.001), LN metastasis (P < 0.001), lymphovascular space invasion (P < 0.001), recurrence (P = 0.001), tumor grade (P < 0.001), and deep myometrial invasion of tumor (P = 0.022). Patient groups categorized by SUV{sub LN} / SUV{sub Tumor} showed significant difference in progression-free survival (Log-rank test, P = 0.001). Preoperative SUV{sub LN} / SUV{sub Tumor} measured by [{sup 18}F]FDG PET/CT was significantly associated with recurrence, and may become a novel prognostic factor in patients with endometrioid endometrial carcinoma.

    Background and study aims  Recent literature suggests that chemo(radio)therapy might reduce the patency of plastic stents in patients with malignant biliary obstruction. Whether this might also be valid for other types of stents is unknown. The aim of this study was to determine the influence of chemo(radio)therapy on the patency of fully-covered self-expandable metal stents (FCSEMSs) and plastic stents. Patients and methods  We retrospectively reviewed the electronic medical records of patients with distal malignant biliary obstruction who underwent biliary stent placement between April 2001 and July 2015. Primary outcome was duration of stent patency. Secondary outcome was stent patency at 3 and 6 months. We used Kaplan–Meier survival analyses to compare stent patency rates between patients who received chemo(radio)therapy and patients who did not. Results  A total of 291 biliary stents (151 metal and 140 plastic) were identified. The median cumulative stent patency of FCSEMSs did not differ between patients receiving chemo(radio)therapy (n = 51) and those (n = 100) who did not ( P  = 0.70, log-rank test). The estimated cumulative stent patency of plastic stents was also comparable in 99 patients without and 41 patients with chemo(radio)therapy ( P  = 0.73, log-rank test). At 3 and 6 months, FCSEMS patency rates were 87 % and 83 % in patients without chemo(radio)therapy and 96 % and 83 % in patients with therapy, respectively. Plastic patency rates were 69 % and 55 % in patients without and 85 % and 39 % in patients with therapy, respectively. After 1 year, 78 % of the FCSEMSs were still patent in patients without chemo(radio)therapy and 69 % of the FCSEMSs were still patent in patients with therapy. Conclusion  Our data indicate that chemo(radio)therapy does not reduce the patency of biliary fully-covered metal and plastic stents. PMID:29090242

    Acute pancreatitis is a common diagnosis worldwide, with gallstone disease being the most prevalent cause (50%). The American College of Gastroenterology recommends urgent endoscopic retrograde cholangiopancreatography (ERCP) (within 24 h) for patients with biliary pancreatitis accompanied by cholangitis. Most international guidelines recommend that ERCP be performed within 72 h in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, but the optimal timing for endoscopy is controversial. We investigated the optimal timing for ERCP in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, and whether performing endoscopy within 24 h is superior to performing it after 24 h. We analyzed the clinical data of 505 patients with newly diagnosed acute pancreatitis, from January 1, 2005 to December 31, 2014. We divided the patients into two groups according to the timing of ERCP: pancreatitis and a bile duct obstruction without cholangitis. The mean age of the patients was 55 years (range: 26-90 years). Bile duct stones and biliary sludge were identified on endoscopy in 45 (61.6%) and 11 (15.0%) patients, respectively. The timing of ERCP within 72 h was not associated with ERCP-related complications (P = 0.113), and the total length of hospital stay was not different between urgent and early ERCP (5.9 vs. 5.7 days, P = 0.174). No significant differences were found in total length of hospitalization or procedural-related complications, in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, according to the timing of ERCP (< 24 h vs. 24-72 h).

    Primary Hodgkin's lymphoma of the colon is a rare phenomenon previously only reported in patients with chronic diverticulitis or inflammatory bowel disease. Herein we report a case of primary Hodgkin's lymphoma of the sigmoid colon in an HIV-positive patient without a history of inflammatory bowel disease or chronic diverticulitis that was later complicated by the discovery of concurrent papillary thyroid carcinoma.

    Hyperthyroidism due to thyroid carcinoma is rare, and most cases are caused by hyperfunctioning metastatic thyroid carcinoma rather than primary carcinoma. Among primary hyperfunctioning thyroid carcinoma, multifocal thyroid carcinoma is exceedingly rare, with the only one case being reported in the literature. Here, we describe the case of a 62-year-old woman with multifocal functioning thyroid carcinoma. Technetium-99m (99m Tc) scintigraphic imaging showed four hot areas in the thyroid gland. Histopathological examination of all four nodules revealed papillary carcinoma, corresponding to hot areas in the 99m Tc scintigram. DNA sequencing of the thyrotropin receptor (TSH-R) gene from all nodules revealed no mutation, indicating that activation of TSH-R was unlikely in the pathophysiogenesis of hyperfunctioning thyroid carcinoma in the present case.

    Full text: To explore the clinical value of PET/CT scanning in search of the primary carcinoma, we selected 4 patients who were subjected to PET/CT examination during Oct. 2002 to Dec. 2002. The primary lesion in all these patients was not detected. One of them had metastasis to liver, one had metastases in both lungs and the other two were having metastases to the bones. 18F-FDG in doses of 5.55MBq / kg body weight was injected to a fasting patient (at least 6 hours). PET/CT whole body examination was done using Discovery LS-PET/CT (GE Medical System, U.S.A.) 40-60 minutes later. In the first patient with metastasis to liver, primary lesion was localized in the transverse colon near the liver. The PET/CT showed multiple high radioactive uptake lesions of different sizes in the liver. No obvious change in position of the colon uptake was seen on the delayed images. After PET/CT, barium examination showed thinned cavity of the colon near the liver with coarse ankylosis of colon wall just like saw tooth. The mucous membrane was destroyed. Of the two patients with metastases in the bone, first - a 31 years old, was diagnosed to have primary lung cancer with multiple metastases to the liver and the bones. PET/CT showed high radioactive uptake in the inferior left lobe near the hilum with irregular shaped uneven distribution. A round high radioactive uptake area of 1.82 x 1.84 x 1.46cm size was also seen in the right lobe of the liver having clear edge and uneven distribution. The destroyed bones (L-10, L-11, L-12, T-1 and ala ossis i lii) showed high radioactive uptake. Second patient, 57-year male was diagnosed to have malignant lymphoma. PET/CT fusion showed high radioactive uptake in the marrow of whole body. Few destroyed parts of bones were also seen on CT images. Several cervical and the thoracic vertebrae as well as the ninth rib showed irregular radioactive accumulation with clear edges and well-distributed tracer raising the possibility of multiple myeloma or

    Diagnostic value of hepatobiliary scintigraphy using mebrofenin-Te-99m was assessed in three newborns with cytomegalovirus (CMV) hepatitis and one baby with hepatitis B jaundice. All cases were affected by persistent jaundice with predominately conjugated bilirubin, alcoholic stools, anemia. One of this newborns (case number 1) was suspected of having biliary atresia due to the absence of intestinal excretion of the tracer. After three weeks intestinal passage was seen in scintiscan late after 24 h. Hepatobiliary scintigraphy represents a non-invasive diagnostic procedure which enables the detection of permeability of the biliary tract. (Author)

    Serum antibody against carbonic anhydrase (CA) II has been described as a serological marker for distinguishing autoimmune cholangitis (AIC) from primary biliary cirrhosis (PBC). To validate this finding in a Japanese population, we evaluated sera from patients with PBC and AIC for antibody to human CA II. An enzyme-linked immunosorbent assay was employed to quantify serum antibody against CA II in patients with PBC (n = 40), AIC (n = 23), autoimmune hepatitis (n = 10), and extrahepatic obstructive jaundice (n = 10). Compared with the finding of a 4% prevalence of anti-CAII antibody in healthy subjects (n = 24), a significantly higher prevalence of anti-CA II antibody was detected in patients with PBC (35%) and AIC (30%) (P jaundice. No significant difference was observed between PBC and AIC patients. These results showed that AIC and PBC would be indistinguishable by anti-CA II antibody testing in Japanese patients. However, the finding of serum anti-CA II antibody in patients with PBC and AIC supports the disease concept of autoimmune exocrinopathy.

    This is a retrospective study of patients with advanced biliary tract carcinoma (BTC), who were treated with different regimens of chemotherapy. We studied patients with advanced BTC registered at the Department of Oncology at the Fundeni Clinical Institute between 2004 and 2008. The following data were analyzed: rate of response, progression free survival (PFS) to first and second line of chemotherapy, overall survival (OS) and drug toxicity. Ninety-six patients were eligible having either advanced intra or extrahepatic cholangiocarcinoma, or gallbladder cancer with no prior chemotherapy. Out of 96 patients, 57 (59.4%) received fluoropyrimidines (FP)+cisplatin and 39 (40.6%) gemcitabine (Gem)+/-cisplatin. The median PFS for FP+cisplatin was 5.9 months (95%CI 5-6.9) and for Gem+/-cisplatin 6.3 months (95%CI 5.4-7.1), p=0.661. Median OS for FP+cisplatin was 10.3 months (95%CI 7.5-13.1) and for Gem+/-cisplatin 9.1 months (95%CI 7.0-11.2), p=0.098. On disease progression, 46 patients received second line CT (Gem or FP+/-platinum compounds). Median OS for patients with FP based first line and Gem+/-cisplatin in second line was 19 months (95%CI 8.9-29) higher than for the reverse sequence: 13.2 months (95%CI 12-14.4), but not statistically significant (p=0.830). All patients were evaluated for toxicities. Most patients (75.5%) reported at least one adverse event. Our results through direct comparison of FP+cisplatin with Gem+/-cisplatin as first line treatment did not show any statistical differences in terms of rate of response, PFS and OS. However, our study showed that FP+cisplatin as first line and Gem based second line therapy gave a better OS rate.

    Objective: Carcinoma of unknown primary (CUP) is not uncommon in usual clinical settings. They are, by definition, those cases with clinically suspected primary malignancy but not revealed by conventional investigation. The aim of this study was to investigate the efficacy of whole-body 18 F-fluoro- deoxyglucose (FDG) PET/CT in detecting a primary neoplasm for these patients. Methods: A totle of 150 patients with retrievable records from 169 CUP patients were selected within a group of consecutive 2589 patients from Jan. 2006 to Jun. 2007. All cases underwent whole-body FDG PET/CT scan. The final diagnoses were confirmed by pathologic results, other imaging modalities or clinical follow-up. Results: Among 150 patients, primary tumor sites were successfully detected by whole-body 18 F-FDG PET/CT scan in 70 cases (46.7%), of which 52 were pathologically confirmed and 18 by clinical follow-up. And 38 cases (54.3%) were lung cancer, 8 (11.4%) were nasopharyngeal carcinoma, 13 (18.6%) in digestive sys- tem, and 11 (15.7%) in other systems. Three clinically suspected CUP cases with negative 18 F-FDG PET/ CT were subsequently confirmed of benign processes by clinical follow-up. Six patients were wrongly diagnosed by 18 F-FDG PET/CT, and 15 patients did not have a confirmed diagnosis by the end of research. The primary cause of malignancy after 18 F-FDG PET/CT remained obscure in 56 patients, only 3 of whom be- came known during the course of clinical follow-up (nasopharyngeal bladder and esophageal carcinoma). Conclusion: 18 F-FDG PET/CT whole-body imaging plays an important role in patients with metastatic CUP. (authors)

    Purpose: To evaluate the feasibility, safety, and clinical benefits of percutaneous laser ablation (PLA) in patients with unresectable primary and metastatic adrenocortical carcinoma (ACC). Patients and methods: Four patients with hepatic metastases from ACC and a Cushing's syndrome underwent ultrasound-guided PLA. In one case the procedure was performed also on the primary tumor. Results: After three sessions of PLA, the primary tumor of 15 cm was ablated by 75%. After 1-4 (median 1) sessions of PLA, five liver metastases ranging from 2 to 5 cm were completely ablated, while the sixth tumor of 12 cm was ablated by 75%. There were no major complications. Treatment resulted in an improvement of performance status and a reduction of the daily dosage of mitotane in all patients. The three patients with liver metastases presented a marked decrease of 24-h urine cortisol levels, an improved control of hypertension and a mean weight loss of 2.8 kg. After a median follow-up after PLA of 27.0 months (range, 9-48 months), two patients have died of tumor progression, while two other patients remain alive and free of disease. Conclusions: Percutaneous laser ablation is a feasible, safe and well tolerated procedure for the palliative treatment of unresectable primary and metastatic ACC. Further study is required to evaluate the impact of PLA on survival.

    With increasing numbers of long survival patients in biliary atresia, associated diseases such as liver cirrhosis and portal hypertension seem to be more important in their course. We use liver scintigraphy, hepatobiliary scintigraphy and transrectal portal scintigraphy as the follow-up study. Three studies generally correlate the present state of the patients, but there seems to be dissociation in the group of cirrhosis without icterus which are encountered most often in biliary atresia. That can be seen in hepatobiliary scintigraphy especially. So we emphasis that to choose several isotope studies are essential in determination of the postoperative state in biliary atresia.

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

    Trichloroethylene (TCE) is a persistent environmental contaminant proposed to contribute to autoimmune disease. Experimental studies in lupus-prone MRL+/+ mice have suggested that TCE exposure can trigger autoimmune hepatitis. The vast majority of studies examining the connection between TCE and autoimmunity utilize this model, and the impact of TCE exposure in other established models of autoimmune liver disease is not known. We tested the hypothesis that TCE exposure exacerbates experimental hepatic autoimmunity in dominant negative transforming growth factor beta receptor type II (dnTGFBRII) mice, which develop serological and histological features resembling human primary biliary cholangitis. Female 8-week-old wild-type and dnTGFBRII mice were exposed to TCE (0.5 mg/ml) or vehicle (1% ethoxylated castor oil) in the drinking water for 12 or 22 weeks. Liver histopathology in 20- and 30-week-old wild-type mice was unremarkable irrespective of treatment. Mild portal inflammation was observed in vehicle-exposed 20-week-old dnTGFBRII mice and was not exacerbated by TCE exposure. Vehicle-exposed 30-week-old dnTGFBRII mice developed anti-mitochondrial antibodies, marked hepatic inflammation with necrosis, and hepatic accumulation of both B and T lymphocytes. To our surprise, TCE exposure dramatically reduced hepatic parenchymal inflammation and injury in 30-week-old dnTGFBRII mice, reflected by changes in hepatic proinflammatory gene expression, serum chemistry, and histopathology. Interestingly, TCE did not affect hepatic B cell accumulation or induction of the anti-inflammatory cytokine IL10. These data indicate that TCE exposure reduces autoimmune liver injury in female dnTGFBRII mice and suggests that the precise effect of environmental chemicals in autoimmunity depends on the experimental model. © The Author 2017.

    2015-12-01

    Full Text Available INTRODUCTION Gall bladder cancer is 5th most common cancer of GIT. It is associated with cholelithiasis in significant number of patients. Cholelithiasis is cause or effect of gall bladder cancer is still uncertain. There are many risk factors which are common to both gall stones and cancer. Preoperative diagnosis of gall bladder cancer is increased with better and new investigation facilities. AIM The study was aimed to assess clinicopathological behaviour, sociodemography, diagnostic modalities and treatment of cancer gall bladder. MATERIAL AND METHODS It was a type of prospective study which included 75 patients with clinical features suggestive of biliary disease. Various diagnostic modalities and treatment options were assessed along with sociodemography and clinical picture. RESULT Common clinical features were pain abdomen, obstructive jaundice and lump. Nearly one third of the patients were having anaemia and abnormal liver function tests. Majority had gall bladder fossa mass with liver extension and gall stones. The most common histopathological variety of carcinoma Gallbladder was Adenocarcinoma. CONCLUSION Carcinoma Gallbladder was found to affect predominantly the older female patients after the age of 40 years. Cholelithiasis was found in 69.3% patients of carcinoma Gallbladder. The most common clinical presentation was pain abdomen (90.7%. The most common histopathological variety of carcinoma Gallbladder was Adenocarcinoma. Majority of patients were treated with palliative measures.

    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: 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.

    Full Text Available We are describing a 19-year-old white woman who presented with two synchronous primary cancers, namely glioblastoma multiforme and papillary thyroid cancer. The patient was admitted with dizziness, headache, and vomiting. CT head revealed acute intraparenchymal hematoma in the right cingulate gyrus and the splenium of the corpus callosum. Carotid and cerebral angiogram were unremarkable. MRI of the brain demonstrated a non-enhancing and non-hemorrhagic component of the lesion along the lateral margin of the hemorrhage just medial to the atrium of the right lateral ventricle that was suspicious for a tumor or metastasis. Brain biopsy confirmed it as glioblastoma mutiforme. CT chest was done to rule out primary cancer that revealed a 11 mm hypodense lesion in the left lobe of the thyroid and ultrasound-guided fine-needle aspiration biopsy confirmed it as papillary thyroid carcinoma. We should evaluate for multiple primary malignancies in young patients who are found to have primary index cancer.

    Full Text Available The present therapy for primary hepatocellular carcinoma (HCC consists of surgery as well as local radiotherapy and chemotherapy. However, the majority of patients are susceptible to recurrence after comprehensive treatment, and the overall treatment outcome is not ideal due to the lack of effective drugs and strategies. Increasing evidence has demonstrated that the immune system is closely related to the development, progression, metastasis, and recurrence of HCC. Thus, immune therapy, especially cellular immunotherapy, could regulate immune function and induce specific antitumor immunity to achieve the goal of controlling HCC and reducing its recurrence and metastasis, which has become an essential part in the comprehensive treatment of HCC. The findings in preclinical and clinical studies on cellular immunotherapy for HCC data are reviewed, and the current problems are discussed.

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

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

    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.

    While fibroblast growth factor receptor 3 (FGFR3) is frequently mutated or overexpressed in nonmuscle-invasive urothelial carcinoma (UC), the prevalence of FGFR3 protein expression and mutation remains unknown in muscle-invasive disease. FGFR3 protein and mRNA expression, mutational status, and copy number variation were retrospectively analyzed in 231 patients with formalin-fixed paraffin-embedded primary UCs, 33 metastases, and 14 paired primary and metastatic tumors using the following methods: immunohistochemistry, NanoString nCounterTM, OncoMap or Affymetrix OncoScanTM array, and Gain and Loss of Analysis of DNA and Genomic Identification of Significant Targets in Cancer software. FGFR3 immunohistochemistry staining was present in 29% of primary UCs and 49% of metastases and did not impact overall survival (P = 0.89, primary tumors; P = 0.78, metastases). FGFR3 mutations were observed in 2% of primary tumors and 9% of metastases. Mutant tumors expressed higher levels of FGFR3 mRNA than wild-type tumors (P < 0.001). FGFR3 copy number gain and loss were rare events in primary and metastatic tumors (0.8% each; 3.0% and 12.3%, respectively). FGFR3 immunohistochemistry staining is present in one third of primary muscle-invasive UCs and half of metastases, while FGFR3 mutations and copy number changes are relatively uncommon

    We evaluated the diagnostic accuracy of 99m Tc-DISIDA scintigraphy as a mean of differentiating biliary atresia from neonatal hepatitis. 99m Tc-DISIDA scintigraphy was visually interpreted by assessing the presence or absence of radioactivity in the intestine or gall bladder. In patients without intestinal radioactivity, we measured the hepatic retention index and the hepatic uptake index. The hepatic retention index was expressed as the amount of change of liver activity from 5 minutes to 30 minutes postinjection. The hepatic uptake index was graded visually with 5 minute images using the following scoring scheme :grade 0 (normal hepatic uptake), grade 1 (decreased hepatic up take), grade 2 (hepatic uptake equal to cardiac uptake), and grade 3 (hepatic uptake less than cardiac uptake). Age, total bilirubin, and hepatic uptake index were compared between the biliary atresia and the neonatal hepatitis group, between neonatal hepatitis patients with and without intestinal radioactivity, and between the biliary atresia and neonatal hepatitis patients with absent intestinal radioactivity. The results were as follows : l) None of the 30 biliary atresia patients showed intestinal radioactivity, while 31/40 neonatal hepatitis patients showed intestinal radioactivity. The sensitivity, specificity, and accuracy of the presence of intestinal radioactivity or the diagnosis of biliary atresia was 100%, 78%, and 87%, respectively. 2) In patients with absent intestinal radioactivity the mean hepatic retention index was 1.5 ± 0.6 in the 16 biliary atresia patient,s, and 1.1 ± 0.2 in the 7 neonatal hepatitis patients(p 99m Tc-DISIDA scintigraphy is accurate in the differential diagnosis of biliary atresia and neonatal hepatitis. In patients without intestinal radioactivity, the hepatic retention index and hepatic uptake index, along with the patients age and total bilirubin level may supplement diagnosis and improve diagnostic accuracy.

    A rare case of primary intraosseous squamous cell carcinoma arising in an odontogenic keratocyst (OKC) is presented here, with the clinical and histologic features of the first biopsy showing characteristics of OKC and the second biopsy disclosing a squamous cell carcinoma. Immunoprofile of this case was compared with five cases of classical OKC by using cytokeratins CK5, CK14, and CK19, CD138, p63, Ki-67, p53, and bcl-2. Classic OKCs showed expected positivity, mainly in the basal and/or suprabasal layers with most antibodies, except for p53, which was negative, whereas the present case showed irregular positivity in all layers, indicating that this can be useful for differential diagnosis and suggesting a possible role in malignant transformation into primary intraosseous squamous cell carcinoma. In conclusion, immunohistochemical differences between the first biopsy of the present case and classic OKC suggest that immunohistochemistry can be helpful in cases with areas of subtle initial malignant transformation.

    Merkel cell carcinoma is an aggressive skin malignancy. Primary Merkel cell carcinomas are treated by wide radical excision with or without adjuvant radiotherapy, while benefits of adjuvant chemotherapy remain doubtful. There are only several cases of gastrointestinal metastases of Merkel cell carcinoma reported so far. We report a case of recurrent Merkel cell carcinoma with metastases to the stomach and the small intestines after wide excision of primary Merkel cell carcinoma.

    2018-02-01

    Full Text Available Lenvatinib is an oral tyrosine kinase inhibitor of vascular endothelial growth factor receptors 1, 2, and 3, fibroblast growth factor receptors 1 through 4, as well as platelet-derived growth factor receptor α, RET, and KIT. At present, lenvatinib is used in the treatment of thyroid cancer and renal cell carcinoma. We herein report a case of a 67-year-old patient with squamous cell carcinoma of unknown primary who was effectively treated with lenvatinib. The patient was initially diagnosed as having undifferentiated thyroid cancer, and after total thyroidectomy and bilateral lymph node dissection, lenvatinib was administered for the treatment of residual lymph node metastasis. A computed tomography scan after 1 month of lenvatinib administration showed marked regression of the lymph nodes, but interstitial pneumonia was also detected. Because the drug lymphocyte stimulation test for lenvatinib was strongly positive, we concluded that the interstitial pneumonia was induced by lenvatinib. The interstitial pneumonia only improved by the withdrawal of lenvatinib. Finally, his thyroid tumor was diagnosed as a metastasis of squamous cell carcinoma; however, we were unable to identify the primary lesion. This is the first reported case of interstitial pneumonia induced by lenvatinib.

    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).

    AIMS: To report two cases of lymph node enhancement in primary hepatic carcinoma following the administration of Mangafodipir trisodium (MnDPDP, Teslascan[reg ], Nycomed Amersham U.K.), an hepatocyte specific magnetic resonance imaging (MRI) contrast agent. To review our experience with this contrast agent and the literature to establish if such enhancement occurs in normal lymph nodes or has been previously described in hepatocellular carcinoma (HCC) or other lesions. MATERIALS AND METHODS: The radiological reports of all MnDPDP enhanced abdominal MRI examinations were reviewed for lymph node enlargement. The MR images from examinations with reported nodal enlargement were re-evaluated for evidence of nodal enhancement and the hospital notes and histological reports were reviewed. Nodal enhancement was considered present if lymph node signal intensity was greater than that of the spleen following MnDPDP. Literature searches were performed on Medline and PubMed for previous descriptions of lymph node enhancement following MnDPDP. RESULTS: The reports of 90 MnDPDP abdominal MRI examinations were reviewed. Of 18 cases of lymph node enlargement, two had evidence of lymph node enhancement following MnDPDP. These two cases had hepatocellular carcinoma and fibrolamellar hepatocellular carcinoma, respectively, confirmed on liver biopsy. No reports of lymph node enhancement following MnDPDP were identified in the literature. CONCLUSION: Two cases of lymph node enhancement following MnDPDP have been presented. Although histological confirmation of the lymph nodes was not obtained, the authors propose that the lymph node enhancement was due to functioning hepatocytes in lymph node metastases from the patients' histologically confirmed hepatocellular carcinomas.

    Aim of the study was to carry out a 5-year survey of German patients with biliary atresia (BA) and to launch a discussion regarding the feasibility of voluntary registries in unregulated healthcare systems. A retrospective analysis of German BA patients born between 2001 and 2005, based on data collected from the voluntary European Biliary Atresia Registry (EBAR), was carried out and supplemented by data from all BA patients who underwent liver transplantation at the only 4 pediatric transplantation centers (pLTx) in Germany which are so far not registered at EBAR. Survival rates were calculated using Kaplan-Meier analysis and compared by Cox regression to determine the predictive value of age at surgery and the influence of the center size (fewer or more than 5 patients/study period) on overall survival and survival with native liver. A critical review of the 148 German EBAR charts revealed that 11 patients (7.4%) had no biliary atresia. The remaining 137 patients from EBAR together with 46 BA patients who underwent LTx without prior registration at EBAR were evaluated with a median follow-up of 39 months (range: 25-85 months). 29 hospitals performed a total of 159 Kasai procedures, but only 7 centers treated 5 or more patients (116 patients, range: 5-68), and 22 hospitals performed less than 5 KP (43 patients, range: 1-4). Primary LTx was performed in 21 patients (11.5%) and 3 patients died without surgical intervention. 16 patients were lost to follow-up (8.7%). Overall survival after 2 years was 83.3% (139 patients), including 105 patients (63%) who had undergone LTx and 34 patients (20.3%) with native liver. 28 patients died (16.7%), 8 after LTx (5.8%). The experience of the center was the only factor with a significant predictive value for jaundice-free survival with native liver (p=0.001). 25% of all German BA patients were not registered at EBAR, and 29 clinics were involved in the surgical management of BA patients. Therefore a new approach consisting of

    Biliary stricture in chronic pancreatitis (CP) is not uncommon. Previously, all cases were managed by surgery. Nowadays, three important modes of treatment in these patients are observation, endoscopic therapy, and surgery. In the modern era, surgery is recommended only in a subset of patients who develop biliary symptoms or tho
