    OBJECTIVE: Newborns routinely receive vitamin K to prevent vitamin K deficiency bleeding. The efficacy of oral vitamin K administration may be compromised in infants with unrecognized cholestasis. We aimed to compare the risk of vitamin K deficiency bleeding under different prophylactic regimens...... in infants with biliary atresia. PATIENTS AND METHODS: From Dutch and Danish national biliary atresia registries, we retrieved infants who were either breastfed and received 1 mg of oral vitamin K at birth followed by 25 microg of daily oral vitamin K prophylaxis (Netherlands, 1991-2003), 2 mg of oral...... vitamin K at birth followed by 1 mg of weekly oral prophylaxis (Denmark, 1994 to May 2000), or 2 mg of intramuscular prophylaxis at birth (Denmark, June 2000-2005) or were fed by formula. We determined the absolute and relative risk of severe vitamin K deficiency and vitamin K deficiency bleeding...

    To determine the outcomes of Canadian children with biliary atresia. Health records of infants born in Canada between January 1, 1985 and December 31, 1995 (ERA I) and between January 1, 1996 and December 31, 2002 (ERA II) who were diagnosed with biliary atresia at a university center were reviewed. 349 patients were identified. Median patient age at time of the Kasai operation was 55 days. Median age at last follow-up was 70 months. The 4-year patient survival rate was 81% (ERA I = 74%; ERA II = 82%; P = not significant [NS]). Kaplan-Meier survival curves for patients undergoing the Kasai operation at age 90 days showed 49%, 36%, and 23%, respectively, were alive with their native liver at 4 years (P < .0001). This difference continued through 10 years. The 2- and 4-year post-Kasai operation native liver survival rates were 47% and 35% for ERA I and 46% and 39% for ERA II (P = NS). A total of 210 patients (60%) underwent liver transplantation; the 4-year transplantation survival rate was 82% (ERA I = 83%, ERA II = 82%; P = NS). This is the largest outcome series of North American children with biliary atresia at a time when liver transplantation was available. Results in each era were similar. Late referral remains problematic; policies to ensure timely diagnosis are required. Nevertheless, outcomes in Canada are comparable to those reported elsewhere.

    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.

    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.

    To describe the ultrasonographic (US) findings of type IIIa biliary atresia. We retrospectively reviewed a medical database of patients pathologically confirmed to have biliary atresia, Kasai type IIIa, between January 2002 and May 2013 (n=18). We evaluated US findings including the visible common bile duct (CBD), triangular cord thickness, gallbladder size and shape, and subcapsular flow on color Doppler US; laboratory data; and pathological hepatic fibrosis grades. We divided them into two groups-those with visible (group A) and invisible (group B) CBD on US-and compared all parameters between the two groups. CBD was visible on US in five cases (27.8%; group A) and invisible in 13 cases (72.2%; group B). US was performed at an earlier age in group A than in group B (median, 27 days vs. 60 days; P=0.027) with the maximal age of 51 days. A comparison of the US findings revealed that the triangular cord thickness was smaller (4.1 mm vs. 4.9 mm; P=0.004) and the gallbladder length was larger (20.0 mm vs. 11.7 mm; P=0.021) in group A. The gallbladder shape did not differ between the two groups, and the subcapsular flow was positive in all cases of both groups. There was no significant difference in the laboratory data between the two groups. Upon pathological analysis, group A showed low-grade and group B showed low- to high-grade hepatic fibrosis. When CBD is visible on US in patients diagnosed with type IIIa biliary atresia, other US features could have a false negative status. A subcapsular flow on the color Doppler US would be noted in the type IIIa biliary atresia patients.

    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.

    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.

    A retrospective review of the abdominal CT scans of 26 children with extrahepatic biliary atresia was performed, and the results were correlated with available surgical and pathologic data. Associated congenital anomalies or acquired abnormalities were identified in these patients. Congenital anomalies included polysplenia, venous anomalies and bowel stenosis. Acquired abnormalities developed secondary to cirrhosis, portal hypertension, intrahepatic biliary duct dilatation, and hepatic ischemia. Despite frequent episodes of ascending cholangitis in these children, no hepatic abscesses were identified by CT or by pathologic examination. In conclusion, abdominal CT scanning of children with extrahepatic biliary atresia can define congenital and acquired abnormalities and provide important anatomic data for the surgeons before liver transplantation.

    Biliary atresia (BA) is the most frequent indication for paediatric liver transplantation. We tested the hypothesis of a viral aetiology of this disease by screening liver samples of a large number of BA patients for the common human hepatotropic viruses. Moreover, we correlated our findings to the expression of Mx protein, which has been shown to be significantly up-regulated during viral infections. Seventy-four liver biopsies (taken during Kasai portoenterostomy) were tested by polymerase chain reaction (PCR) for DNA viruses (herpes simplex virus [HSV], Epstein-Barr virus [EBV], varicella zoster virus [VZV], cytomegalovirus [CMV], adenovirus, parvovirus B19 and polyoma BK) and RNA viruses (enteroviruses, rotavirus and reovirus 3). Mx protein expression was assessed by immunohistochemistry. Virus DNA/RNA was found in less than half of the biopsies (8/74 CMV, 1/74 adenovirus; 21/64 reovirus, 1/64 enterovirus). A limited number presented with double infection. Patients that had detectable viral RNA/DNA in their liver biopsies were significantly older than virus-free patients (P = 0.037). The majority (54/59) of the liver biopsies showed expression of Mx proteins in hepatocytes, bile ducts and epithelium. Our data suggest that the known hepatotropic viruses do not play a major role in the aetiology and progression of BA. Their incidence appears to be, rather, a secondary phenomenon. Nonetheless, the inflammatory response in the livers of BA patients mimics that observed during viral infections.

    Extrahepatic biliary atresia (EHBA), the etiology of which still remains unclear, occurs exclusively in newborns and has recently been simulated in an animal model. It is possible to trigger an EHBA corresponding to the human disease by means of intraperitoneal infection of newborn Balb/c mice with rhesus rotavirus (RRV). The aim of the present study was to determine the conditions and circumstances for inducing biliary atresia in this model focusing on first-line immunological aspects. Newborn as well as pregnant Balb/c mice were intraperitoneally infected with RRV. The highest incidence of cholestasis (86%) was achieved by infection with 10(6) PFU/ml RRV within the first 12 h postpartum, resulting in EHBA with a lethality of 100%. However, the later the newborn mouse is infected, the less likelihood there is that EHBA is triggered. Additionally, the incidence of biliary atresia in this model depends on the quantity of the virus that is given intraperitoneally. However, the development of biliary atresia is not correlated to the virus in the liver. The antepartum infection of pregnant mice does not induce EHBA in the offspring. Female mice that are immunized against RRV protect their newborns from developing RRV-induced cholestasis and EHBA. This protection is transmitted transplacentally and not by breast milk. It is obvious that a temporary immunological gap is essential for virally induced EHBA. Further studies should focus on specific parameters of the immune system of newborn mice in this biliary atresia model. Copyright 2001 Academic Press.

    We report a 3.5-month-old boy with polysplenia syndrome who demonstrated hemiazygos continuation of the inferior vena cava, extrahepatic biliary atresia, multiple splenunculi, bowel malrotation, and the rare finding of brainstem and cerebellar hypoplasia. A possible pathogenesis for cerebellar hypoplasia in this syndrome is suggested after review of the literature. The importance of seeking associated anomalies in biliary atresia, which may be possible indicators of polysplenia syndrome, is stressed since these patients need appropriate management when surgery is considered.

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

    The infantile cholangiopathies are a group of conditions associated with neonatal jaundice, which include extrahepatic biliary atresia, paucity of intra-hepatic bile ducts and disorders associated with persistence of fetal biliary structures, the so-called ductal plate malformations. Although previously regarded as distinct entities, it has recently been suggested that they may represent parts of a disease spectrum in which the principal process is one of bile duct destruction, the morphological manifestations in individual cases being influenced by the stage of intra-uterine development at which such injury occurs and by the site within the biliary system at which there is maximum damage. To further examine this concept, we have studied liver biopsy specimens from 37 neonates with extrahepatic biliary atresia, with particular reference to abnormalities of the intrahepatic bile ducts. Paucity of intrahepatic ducts, defined as a bile duct: portal tract ratio of less than 0.9, was identified in six cases (16.2%). In eight cases (21.6%) we found concentric tubular ductal structures similar to those observed in ductal plate malformations. In one case, both abnormalities could be demonstrated. Our findings support the concept that there is overlap between the various types of infantile cholangiopathy.

    2008-01-01

    Kasai's operation has proved its value in surgical treatment of biliary atresia (BA). Its laparoscopic approach is a new challenge for pediatric surgeons, with all the potential advantages of minimally invasive surgery. The aim of the present study has been to report our experience in laparoscopic management of five patients with biliary atresia. The average of age of five patients with biliary atresia, three boys and two girls was 58 days (range 40-64). Pre and postoperative management included antibiotic prophylaxis and choleretic treatment. Laparoscopic procedure was accomplished using one umbilical 10-mm trocar and two additional 5-mm trocars. We carried out the same technique in all the patients except in one of them with a total situs inversus and who compelled us to modify the original procedure. All five patients underwent a laparoscopic procedure, conversion was not necessary. The mean surgical time was 3 hours and 40 minutes (range: 5:30 y 3:10). There were not intra operative complications and all of them had a satisfactory recovery, except for the patient with situs inversus, who suffered a small bowel volvulus 9 days after the operation, leading us to perform an extensive bowel resection. All the patients, except this one, showed signs of adequate bile flow, with disappearance of clinical cholestasis. Biochemistry test became normal. Besides the certain advantages compared with conventional surgical procedures (lower surgical damage, diminished post-operative recovery), laparoscopic management of BA, allows a better exposure of the porta hepatis without hepatic mobilization so it shows similar or better preliminary results than conventional techniques. The advantages of laparoscopic portoenterostomy are yet to be proved whenever liver transplantation is indicated.

    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

    The features of Goldenhar complex have been well-described and classically include branchial arch abnormalities, epibulbar dermoid and vertebral abnormalities. We have identified an infant with these features in association with complex congenital heart disease and intrahepatic biliary atresia. Although Lambert described an autosomal recessive disorder with an association of biliary atresia and branchial arch abnormalities, none of those cases had epibulbar dermoid. Diagnostic considerations in this case include inclusion of biliary atresia as a new feature in the expanding spectrum of the Goldenhar complex, versus Lambert syndrome with epibulbar dermoid.

Pathway analysis of the 1000 top-ranked SNPs in CHP cases revealed enrichment of genes for EGF regulators (p<1 x10-7, ERK/MAPK and CREB canonical pathways (p<1 x10-34, and functional networks for cellular development and proliferation (p<1 x10-45, further supporting the role of EGFR-ARF6 signaling in BA. In zebrafish embryos, Mo-arf6 injection resulted in a sparse intrahepatic biliary network, several biliary epithelial cell defects, and poor bile excretion to the gall bladder compared with uninjected embryos. Biliary defects were reproduced with the EGFR-blocker AG1478 alone or with Mo-arf6 at lower doses of each agent and rescued with arf6 mRNA.The BA-associated SNPs identify a chromosome 14q21.3 susceptibility locus encompassing the ARF6 gene. arf6 knockdown in zebrafish implicates early biliary dysgenesis as a basis for BA, and also

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

    To reestablish the size criterion of the gallbladder on ultrasonography (US) for the differentiation diagnosis of biliary atresia from neonatal hepatitis. Abdominal US ws performed in 201 patients with jaundice and 40 patients without evidence of jaundice or hepatobiliary illness (all with the age less than 4 months). US was performed in fasting (fasting for at least 4 hours) to measure the length of the gallbladder and calculated the area of the gallbladder lumen. The morphology of the gallbladder was classified into three types: normal, elongated and atretic. To evaluate the contractibility of the gallbladder, the length of the gallbladder and area of the gallbladder lumen was again measured 1 hour after feeding. The final diagnosis included biliary atresia in 79 patients and neonatal hepatitis in 83 patients. Differences in the length, area, and morphology of the gallbladder were statistically significant among three groups, the normal group, neonatal hepatitis group and biliary atresia group (length and area of gallbladder; normal group>neonatal hepatitis>biliary atresia). The differences in the length and area of gallbladder between pre- and postmeal state were statistically significant in the normal and neonatal hepatitis groups whereas those of biliary atresia were not significant (p=0.85). When the empirical size criterion of the gallbladder (<15 mm in length) was applied, the sensitivity, specificity and diagnostic accuracy for the differential diagnosis of biliary atresia from hepatitis were 52%, 82%, and 67%, respectively. Meanwhile, if the area criterion(<30 mm{sup 2} in area) was applied, the sensitivity, the specificity and diagnostic accuracy were 67%, 85%, and 75%, respectively. Ultrasonographic evaluation of the morphology as well as size of the gallbladder are helpful in the differential diagnosis of biliary atresia from neonatal hepatitis. Therefore, since the measurement of the area of gallbladder lumen on US reflect both size and morphology of

    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.

    Hepatic portoenterostomy (Kasai operation) for the patient with biliary atresia (BA) can restore the bile flow in approximately 80% of children operated on before 60 days of life [1]. However, in terms of long-term survival, according to a recent nationwide survey among the major pediatric centers in Japan, only 325 of 2013 patients had more than 10 years' survival, and only 157 patients (7.8%) remained jaundice-free with normal liver function [2]. About 20% of BA cases without jaundice are generally able to survive for long periods; and most of those patients have portal hypertension or abnormal liver function [3-5]. As the results of liver transplantation have improved, controversy has arisen over the optimal care of these children [4, 6, 7]. Some investigators have claimed that transplantation is the favored primary therapy for most patients with BA [8]. We are thus at a turning point concerning the primary therapy of BA, which makes it necessary to determine the exact indications for the Kasai portoenterostomy and the timing of liver transplantation. This paper describes our strategy for the optimal treatment of BA patients based on our 117 patients who have had various form of portoenterostomy.

    Biliary atresia (BA) is a rare neonatal cholestatic disorder caused by obstruction of extra- and intra-hepatic bile ducts. If untreated, progressive liver cirrhosis will lead to death within 2 years. Early diagnosis and operation improve the outcome significantly. Infants with neonatal hepatitis syndrome (NHS) present similar symptoms, confounding the early diagnosis of BA. The lack of noninvasive diagnostic methods to differentiate BA from NHS greatly delays the surgery of BA infants, thus deteriorating the outcome. Here we performed a metabolomics study in plasma of BA, NHS, and healthy infants using gas chromatography-time-of-flight mass spectrometry. Scores plots of orthogonal partial least-squares discriminant analysis clearly separated BA from NHS and healthy infants. Eighteen metabolites were found to be differentially expressed between BA and NHS, among which seven (l-glutamic acid, l-ornithine, l-isoleucine, l-lysine, l-valine, l-tryptophan, and l-serine) were amino acids. The altered amino acids were quantitatively verified using ultraperformance liquid chromatography-tandem mass spectrometry. Ingenuity pathway analysis revealed the network of "Cellular Function and Maintenance, Hepatic System Development and Function, Neurological Disease" was altered most significantly. This study suggests that plasma metabolic profiling has great potential in differentiating BA from NHS, and amino acid metabolism is significantly different between the two diseases.

    Purpose: We retrospectively evaluated the technical and long-term clinical results of transjugularintrahepatic portosystemic shunts (TIPS) in children with portal hypertension and biliary atresia (BA). Methods: Nine children with BA and recurrent bleeding from esophagogastric and/or intestinal varices were treated by TIPS at the age of 34-156 months and followed-up in two centers. Different types of stents were used. Results: Shunt insertion succeeded in all patients, but in two a second procedure was necessary. Seven procedures lasted more than 3 hr, mainly due to difficult portal vein puncture.Variceal bleeding ceased in all patients; however, 16 reinterventions were performed in eight patients for clinical reasons (n =11) and sonographically suspected restenosis (n =5). Four patients underwent successful liver transplantation 4-51 months after TIPS and five are in good clinical conditions 64-75 months after TIPS. Conclusions: TIPS in children with BA is technically difficult, mainly due to periportal fibrosis and small portal veins. Frequency of reinterventions seems to be higher compared with adults

    Full Text Available A case of monozygotic twins, one of whom suffered from biliary atresia and the other one was apparently healthy, is described herein. Children with biliary atresia appear to be vulnerable to developmental lags in the physical and cognitive performance, due to malnutrition and deteriorated liver function. In our case where the child with biliary atresia, who underwent a successful kasai operation, has achieved comparable growth development and cognitive performance in comparision with her sister, which suggest that the early diagnosis and timly kasai operation could allow children with biliary artesia to grow well in the short-term following time.

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

    Diagnosing biliary atresia (BA) quickly is critical, because earlier treatment correlates with delayed or reduced need for liver transplantation. However, diagnosing BA quickly is also difficult, with infants usually treated after 60 days of life. In this study, we aim to accelerate BA diagnosis and treatment, by better understanding factors influencing the diagnostic timeline. Infants born between 2007 and 2014 and diagnosed with BA at our institution were included (n = 65). Two periods were examined retrospectively: P1, the time from birth to specialist referral, and P2, the time from specialist referral to treatment. How sociodemographic factors associate with P1 and P2 were analyzed with Kaplan-Meier curves and Cox proportional hazard models. In addition, to better characterize P2, laboratory results and early tissue histology were studied. P1 associated with race/ethnicity, with shorter times in non-Hispanic white infants compared to non-Hispanic black and Hispanic infants (P = 0.007 and P = 0.004, respectively). P2 associated with referral age, with shorter times in infants referred after 30, 45, or 60 days of life (P P2 in infants referred ≤30 days is that aminotransferase levels were normal or near-normal. However, despite reassuring laboratory values, tissue histology in early cases showed key features of BA. Our findings suggest 2 opportunities to accelerate BA diagnosis and treatment. First, to achieve prompt referrals for all races/ethnicities, universal screening strategies should be considered. Second, to ensure efficient evaluations independent of age, algorithms designed to detect early features of BA can be developed.

  20. Endotoxin and CD14 in the progression of biliary atresia

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

    Bile duct atresia (BVA) is a condition that causes obstruction to biliary flow, not corrected surgically, causes cirrhosis and death before 2 years of age. In Mexico from 2013 the visual colorimetric card (VVC) was incorporated for the timely detection of BVA to the National Health Card (NHC). The aim of this study was to evaluate the impact of VCT for the detection of BVA before and after the use of NHC incorporation. Ambispective, analytical observational study. We included patients with AVB treated in two pediatric hospitals of third level care. We compared the age of reference, diagnosis and surgery before and after incorporation of the TCV. In addition, a questionnaire was made to the parents to know their perception about the TCV. In 59 children, there were no differences in age at diagnosis (75 vs 70 days) and age at surgery (84 vs 90 days) between the pre and post-implementation period of the VVC. The questionnaire showed that 10 (30%) of the parents received information about the use of the VVC and 13 (38%) identified the abnormal evacuations. This study did not show changes in time for the timely detection of BVA by using VVC. Therefore, it is necessary to reinforce the program in the three levels of care in our country. La atresia de vías biliares (AVB) es una condición que provoca obstrucción al flujo biliar, y de no corregirse quirúrgicamente, provoca cirrosis y la muerte antes de los 2 años de edad.

    Introduction: At least 40% of survivors of biliary atresia have progressive cirrhosis even after undergoing Kasai operation. The values of hepatic apparent diffusion coefficient and apparent-diffusion-coefficient-related indices were applied to biliary atresia patients and correlated with cirrhotic severity scores of model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte, and Child-Pugh systems. Materials and methods: Thirty-three biliary atresia patents (mean = 1140, 61–4314 days of age) received magnetic resonance image examinations due to complications of biliary atresia from April 2008 to August 2009. Two non-breath-hold diffusion weighted imaging sequences were performed with motion-probing gradients in three directions with two b values: 0/100 and 0/500 s/mm 2 ; 1000 ms/61.1 ms, time to repeat/time to echo; number of excitation, 1.0; 8 mm section thickness; 40 cm × 40 cm field of view; 128 × 256 matrix in all biliary atresia patients and 18 control subjects. We used the Spearman rank correlation test to analyze the relationship among the scores of model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte and Child-Pugh scores and right hepatic apparent diffusion coefficients, apparent diffusion coefficient using b factor of 500-albumin product and alanine transaminase/apparent diffusion coefficient with b factor of 500 ratio. Results: The right hepatic apparent diffusion coefficient using b factor of 100, apparent diffusion coefficient with b factor of 500 and product of apparent diffusion coefficient with b factor of 500-albumin level were significantly negatively correlated (p ≤ 0.0125) with model for end-stage liver disease or pediatric end-stage liver disease model, Child-Turcotte, and Child-Pugh scores of biliary atresia patients. The ratio of alanine transaminase level/right hepatic apparent diffusion coefficient with b factor of 500 was also significantly (p ≤ 0

    The results obtained from scintigraphic hepatobiliary function studies, intraoperative cholangiography and histological examinations in a total of 17 infants suspected of having biliary atresia were compared and analysed with reference to the clinical signs and symptoms observed. In most cases, the individual diagnostic procedures led to consistent findings, even though there were some variations in the clinical picture. Patient outcome is largely determined by the site of atresia, due to which fact surgical correction should be carried out as soon as possible, in any case before the 8th week post partum. (TRV) [de

    With reference to three cases, the value of cholescintigraphy for the diagnosis of biliary atresia is underscored. With this procedure, surgical indications can be determined in neonates with jaundice persisting beyond the physiologic period. Clolescintigraphy can be repeated as it is easy to perform, safe and well tolerated. sup(99m)Tc-diethyl-IDA (technetium 99m labelled N-(2,6 diethyl-acetanilide)-iminodiacetic acid) scintigraphy was carried out in eight neonates. This procedure helped to outrule the diagnosis of biliary atresia in 5 cases (1 choledochal cyst, 1 alpha-1-antitrypsin deficiency and 3 neonatal hepatitis'). Scintigraphic images and time/activity curves generated simultaneously from equal surfaces over the heart and liver were analyzed separately. A good uptake by the liver (rapid decrease in the cardiac curve) with subsequent retention (no decrease in the hepatic curve) is suggestive of biliary atresia. No activity is detected in the biliary ducts or intestinal tract. Post-operatively, cholescintigraphy is a useful tool for controling the efficiency of the surgical procedure.

    Introduction: Chronic liver disease increases portal vein pressure and modifies splanchnic circulation. This is particularly significant in infants with biliary atresia. Large collaterals steal portal flow and increase the risk of post transplant portal vein thrombosis. Objective: to describe different types of portosystemic collaterals prior to liver transplantation with low-dose multidetector CT (MDCT) in patients with biliary atresia. Material and methods: 13 patients with severe liver dysfunction due to biliary atresia underwent low-dose 64-MDCT before liver transplantation (effective tube current ranged from 20 to 120 mAs according to weight, with a kilo voltage of 80-120 for all CT). Hepatic arterial and portal venous phases were performed after IV contrast administration [1.5-2 ml/kg]. The mean age of the study group was1 year (range, 4 months to 3.6 years). Two radiologists reviewed the CT images to determine the grade and types of the portosystemic collaterals. Results: A total of 16 CT scans were obtained.the most common portosystemic collaterals found were esophageal (11), gastric submucosal (8), gastric adventitial (7, splenic (7), hemorrhoidal (10), mesenteric [dilated or tortuous branches of the inferior mesenteric vein (8)], retroperitoneal varices [gastro renal shunt (10), splenorenal shunt (4)] and dilated or tortuous left gastric vein (13). Conclusion: MDCT provides important information on venous system patency, presence of varices, and location of venous shunts in pediatric patients with biliary atresia going to liver transplant. in addition, it is critical to detect collaterals that are not evident on ultrasound in order to avoid the steal phenomenon that may lead to portal vein thrombosis and graft failure.

    To evaluate MRI findings and to generate a decision tree model for diagnosis of biliary atresia (BA) in infants with jaundice. We retrospectively reviewed features of MRI and ultrasonography (US) performed in infants with jaundice between January 2009 and June 2016 under approval of the institutional review board, including the maximum diameter of periportal signal change on MRI (MR triangular cord thickness, MR-TCT) or US (US-TCT), visibility of common bile duct (CBD) and abnormality of gallbladder (GB). Hepatic subcapsular flow was reviewed on Doppler US. We performed conditional inference tree analysis using MRI findings to generate a decision tree model. A total of 208 infants were included, 112 in the BA group and 96 in the non-BA group. Mean age at the time of MRI was 58.7 ± 36.6 days. Visibility of CBD, abnormality of GB and MR-TCT were good discriminators for the diagnosis of BA and the MRI-based decision tree using these findings with MR-TCT cut-off 5.1 mm showed 97.3 % sensitivity, 94.8 % specificity and 96.2 % accuracy. MRI-based decision tree model reliably differentiates BA in infants with jaundice. MRI can be an objective imaging modality for the diagnosis of BA. • MRI-based decision tree model reliably differentiates biliary atresia in neonatal cholestasis. • Common bile duct, gallbladder and periportal signal changes are the discriminators. • MRI has comparable performance to ultrasonography for diagnosis of biliary atresia.

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

    -note review for infants with definite BA who underwent laparotomy within first week of life. RESULTS: Three infants were identified who had occlusive BA evident on the first day of life. In all cases, their liver was grossly normal, and histologic changes were trivial. CONCLUSION: This suggests...... that the detrimental cholestatic liver injury, later characteristic of BA, only begins from the time of birth despite a prenatal occlusive biliary pathology. It may be that tissue injury only occurs with the onset of the perinatal bile surge initiating periductal bile leakage and the triggering of an inflammatory...

  13. 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.

    Full Text Available Extrahepatic biliary atresia (EHBA is an uncommon cause of neonatal jaundice. Antenatal Magnetic Resonance Imaging (MRI diagnosis of EHBA has not been published to the best of our knowledge till date. EHBA with cystic component is likely to be mistaken for choledochal cyst. A case that was antenatally predicted and postnatally confirmed by surgery and histopathology is being reported. All imaging signs are analyzed herewith. Imaging helps in the prediction of EHBA and also helps in early postnatal surgical referral which in turn improves the results of Kasai′s portoenterostomy.

    RI hepatgram with sup(99m)TcO/sub 4/ was developed for the evaluation of the changes in hepatic circulation in liver cirrhosis in 41 cases of pediatric liver diseases including 25 cases of biliary atresia. After bolus intravenous injection of 1-5 mCi of sup(99m)TcO/sub 4/ radioactive count over the abdomen was measured by a scinticamera for ten minutes. Time activity curve of a ROI on the liver right lobe was drawn for ten minutes. The count reached to plateau about one minute after injection and gradually decreased thereafter. The ratio of the counts of eight minutes to the plateau was calculated. It ranged from 49% to 98%, and this ratio correlated well with the physical and laboratory findings of liver cirrhosis. There is a significant correlation between the ratio and liver fibrosis. Most of the cases (4/5) that showed over 80% were accompanied by gastrointestinal bleeding due to portal hypertension. This method can be used for postoperative follow-up of liver cirrhosis of biliary atresia to predict G-I bleeding as it is easily performed, almost noninvasive and easily repeated. (author).

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

    The objective of the present study is to evaluate whether IL-6, TNF-α, IL-10 are associated with nutritional status in patients with cirrhosis secondary to biliary atresia and compare to healthy controls. The parameters used for nutritional assessment were the standard deviation scores of height-for-age and of triceps skinfold thickness-for-age. The severity of cirrhosis was evaluated using the Child-Pugh score and PELD/MELD. Serum cytokines were measured using Cytometric Bead Array flow cytometry. IL-6, TNF-α, and IL-10 were significantly higher in the cirrhosis group when compared with the control group (2.4 vs. 0.24 (patresia, IL-6 could be used as a possible supporting biomarker of deficient nutritional status and elevated IL-10 levels could be used as a possible early-stage supporting biomarker of deteriorating nutritional status.

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

    ós-portoenterostomia.Objective: this study considered the presence of congenital anomalies, ductal plate malformation, area of fibrosis and, mainly, the patient's age in cases of biliary atresia submitted to surgery. The present study verified the influence of these factors on the follow-up of a biliary atresia sample. Methods: a sample of 47 patients with biliary atresia was evaluated in a cross-sectional study. Their histologic specimens were stained for antibody anticytokeratin 19 and CAM 5.2 through immunohistochemistry in order to study biliary structures, and for picrosirius red to evaluate the area of fibrosis. The study of biliary structures was performed by two pathologists and the first author of the study. They were "blind" with regard to the clinical follow-up. The area of fibrosis was quantitatively evaluated. Data on the patients with regard to age, death and occurrence of liver transplantation were searched on the patients records. Results: age at portoenterostomy varied between 24 and 251 days of life (90.4 ±44.8 days and follow-up was available in 32 cases (72%. The nine cases (19% with extrahepatic congenital anomalies associated to biliary atresia did not present different prognosis from the remaining patients. Age at portoenterostomy influenced the prognosis (p=0.016. The area of fibrosis was different on patients aged less than 60 days and those aged more than 90 days at portoenterostomy (p=0.023, but did not influence the prognosis. The presence of ductal plate malformation, as well, did not influence the follow-up. Conclusions: age at portoenterostomy was the only factor that influenced prognosis on this sample of biliary atresia. It is necessary to increase the biliary atresia sample to check the influence of congenital extrahepatic anomalies on the follow-up post-portoenterostomy.

    A proposed etiopathogenesis of biliary atresia (BA) involves T-cell-mediated inflammatory bile duct damage and progressive hepatic fibrosis. Pediatric surgeons often observe swelling of the hepatic hilar lymph nodes during the Kasai procedure. Given the importance of regulatory mechanisms in immune responses, the present study was designed to analyze the quantitative changes of regulatory T cells (T reg cells) in the hepatic hilar lymph nodes (hepatic hilar LNs) and peripheral blood (PB) in BA. The hepatic hilar LNs and PB obtained during the Kasai procedure were analyzed by flow cytometry. The ratios of total and active Tregs to the total CD4 + cells in the PB and the hepatic hilar LNs were compared. In patients with BA, the ratios of both the total and active T reg cells in the hepatic hilar LNs were higher than those in the PB (total T reg cells: PB vs. LN; P hilar lymph nodes of BA patients. This finding could shed light on the pathogenesis of BA.

    To evaluate the outcome of Scottish children with extra hepatic biliary atresia (EHBA) since rationalisation of Kasai services to three English centres in 2002 (The 'Group A' centres). All Scottish children with EHBA diagnosed between 2002 and 2009 were identified via the Scottish Society of Paediatric Gastroenterology, Hepatology and Nutrition (SSPGHAN) clinicians. A case-note review was conducted with demographics, presentation and outcome data recorded. These data were compared with historical Scottish data and data published previously by the supraregional liver units. 25 patients were identified, of whom 22 were referred for Kasai in the group A centres, and of whom 19 had a Kasai. 2 year transplant-free survival (TFS) was significantly lower in the SSPGHAN 2002-2009 group than the group A centres in (1) (6/18 (33%) vs 36/57 (63%), p=0.023). These postrationalisation data are disappointing. The emphasis for care will now focus on improved communication between, primary care, general paediatricians and surgical centres through regional and national managed clinical networks, aiming to improve future outcomes for Scottish children with BA.

    Full Text Available Objectives. To assess bone health in a cohort of nonjaundiced children with biliary atresia (BA and the effect of growth and development on bone outcomes. Methods. Children ages one to eighteen years receiving care from Children's Hospital of Philadelphia were recruited. Each child was seen once and assessed for growth, pubertal development, concurrent medications, bilirubin, ALT, albumin, vitamin D status, bone mineral density (BMD, and bone mineral content (BMC of the lumbar spine and whole body. Results. BMD declined significantly with age, and upon further analysis with a well-phenotyped control cohort, it was found that BMC was significantly decreased for both lumbar spine and whole body, even after adjustment for confounding variables. An age interaction was identified, with older subjects having a significantly greater impairment in BMC. Conclusions. These preliminary results demonstrate that children with BA, including those without jaundice, are likely to have compromised bone health even when accounting for height and puberty, which are common confounding factors in chronic disease. Further investigation is needed to identify the determinants of poor bone mineral status and to develop strategies to prevent osteoporosis later in life.

    Biliary atresia (BA) occurs in 0.54 of 10.000 of overall live births in the Netherlands. BA has an unfavorable prognosis: Netherlands. Retrospective study including Dutch preterm infants treated for BA. Parameters included gestational age, congenital anomalies, age at KPE, days between first symptoms, and KPE and referral interval (first hospital to KPE). Outcome parameters were clearance of jaundice (COJ) and (transplant-free) survival. Data are presented as medians (ranges). Included 28 preterm infants (13 boys/15 girls) between March 1988 and December 2015. The incidence of BA was 1.06 of 10.000 preterm live births. Gestational age was 34.8 (27.3-36.9) weeks. Congenital anomalies were present in 11 of 28 (39%) infants. Time between first symptoms and KPE was 57 (9-138) days. Referral interval was 28 (8-86) days. Age at KPE was 70 (35-145) days. COJ was achieved in 23% of cases. Four-year transplant-free survival rate was 21%. Four-year overall survival was 61%. BA has a higher incidence in the preterm population compared to the overall BA population. The outcome of BA in preterm infants is poor, regarding COJ and (transplant-free) survival. We speculate that timely recognition of BA-related signs and symptoms in preterm infants will improve prognosis.

    Bacterial cholangitis (BC) is a common complication in patients with biliary atresia (BA) and is characterized by fever, acholic stools and positive blood cultures. The diagnosis is often empirical because the yield of blood cultures is low. It is difficult to differentiate BC from other febrile episodes. In order to characterize the clinical and laboratory features of BC in patients with BA, identify risk factors, and correlate cholangitis with outcome, 37 patients with BA from 1993 to 1998 who underwent a Kasai operation in our hospital were studied. The follow-up period ranged from 6 to 59 months. A total of 107 febrile episodes were documented in these patients. The diagnostic criteria for cholangitis were fever, increased jaundice, or acholic stools. The clinical features, laboratory data, results of bacterial cultures, and outcomes were analyzed retrospectively. A total of 107 febrile episodes, including 78 bouts of cholangitis and 29 non-cholangitis infections, were found in 34 patients. Patients with BC had higher postoperative bilirubin levels (P = 0.02) and less frequent use of prophylactic antibiotics (P = 0.05) than those with non-cholangitis infections. Abnormal white blood cell counts (> 12,000 or Acinetobacter baumanni, and Salmonella typhi. The sensitivity tests justified empirical therapy with ceftriaxone. The effectiveness of prophylactic trimethoprim-sulfamethoxazole or neomycin warrants further studies. BC was a highly prevalent postoperative complication in patients with BA, especially those with inadequate bile drainage. It significantly affected early mortality. Aggressive and complete treatment with empirical ceftriaxone was appropriate.

    There is currently no unified view regarding whether liver transplantation or splenectomy should be performed for hypersplenism before liver transplantation in biliary atresia (BA) patients. We herein describe the efficacy of splenectomy before liver transplantation. Splenectomy was performed in ten patients with hypersplenism associated with BA. We retrospectively reviewed their perioperative and postoperative courses, the number of leukocytes and thrombocytes, and the MELD score. The mean age was 17.5±7.0years (range 11-31years), and the male-to-female ratio was 1:1. The platelet and leukocyte levels increased after splenectomy and returned to normal levels one month postoperatively. The mean MELD score after splenectomy was significantly decreased after splenectomy: 10±2.1 vs 7.6±1.8. In particular, PT-INR improved. Five patients underwent liver transplantation because of hepatopulmonary syndrome and repeated bouts of cholangitis, whereas the remaining five patients did not undergo liver transplantation because of improvements in the liver function (the mean follow-up period was 56months). The postoperative complications included portal vein thrombosis and intestinal perforation, but the patient survival rates remained at 100%. After splenectomy, both pancytopenia and the liver function clearly improved. Splenectomy should therefore be a treatment option for patients with hypersplenism before liver transplantation.

    Full Text Available The purpose of this study was to investigate the association of telomere length in peripheral blood leukocytes with the severity of biliary atresia (BA.One hundred and fourteen BA patients and 114 age-matched healthy controls were enrolled. Relative telomere length (RTL was assessed using a quantitative real-time polymerase chain reaction. Multivariate regression analysis was used to estimate RTL as an independent risk factor of BA. Receiver operating characteristic curve analysis was used to calculate the accuracy of biomarkers in the prediction of liver cirrhosis.BA patients had significantly shorter telomeres than healthy controls (p < 0.0001. The RTL in BA patients with jaundice was considerably lower than that of patients without jaundice (p = 0.005. Moreover, RTL was markedly shorter in patients with cirrhosis (F4, as compared to patients with mild fibrosis (F2 and non-fibrosis (F0-F1, p < 0.0001. Logistic regression analysis indicated that short RTL was associated with a higher risk of liver cirrhosis in BA. Tertile analysis showed a dose-response effect for this association (p trend < 0.0001. Additionally, RTL in BA children revealed a negative correlation with age (r = -0.50, p < 0.001. We noted an association between reduction of RTL and liver stiffness scores, adjusted for age and gender (b = -0.01, p < 0.0001. Short RTL can be employed to distinguish cirrhosis patients from non-cirrhosis patients (AUC = 0.78. Further analysis showed a linear correlation between leukocyte RTL and liver RTL in BA patients (r = 0.83, p < 0.001.The findings of this study provide evidence that telomere shortening is associated with an elevated risk of liver cirrhosis in BA.

  13. Association between Promoter Hypomethylation and Overexpression of Autotaxin with Outcome Parameters in Biliary Atresia.

    Wanvisa Udomsinprasert

    Full Text Available Biliary atresia (BA is a progressive fibroinflammatory liver disease. Autotaxin (ATX has a profibrotic effect resulting from lysophosphatidic acid activity. The purpose of this study was to examine ATX expression and ATX promoter methylation in peripheral blood leukocytes and liver tissues from BA patients and controls and investigate their associations with outcome parameters in BA patients.A total of 130 subjects (65 BA patients and 65 age-matched controls were enrolled. DNA was extracted from circulating leukocytes and liver tissues of BA patients and from and age-matched controls. ATX promoter methylation status was determined by bisulfite pyrosequencing. ATX expression was analyzed using quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay.Decreased methylation of specific CpGs were observed at the ATX promoter in BA patients. Subsequent analysis revealed that BA patients with advanced stage had lower methylation levels of ATX promoter than those with early stage. ATX promoter methylation levels were found to be associated with hepatic dysfunction in BA. In addition, ATX expression was significantly elevated and correlated with a decrease in ATX promoter methylation in BA patients compared to the controls. Furthermore, promoter hypomethylation and overexpression of ATX were inversely associated with jaundice status, hepatic dysfunction, and liver stiffness in BA patients.Accordingly, it has been hypothesized that ATX promoter methylation and ATX expression in peripheral blood may serve as possible biomarkers reflecting the progression of liver fibrosis in postoperative BA. These findings suggest that the promoter hypomethylation and overexpression of ATX might play a contributory role in the pathogenesis of liver fibrosis in BA.

    To assess the diagnostic value of various ultrasound (US) findings and to make a decision-tree model for US diagnosis of biliary atresia (BA). From March 2008 to January 2014, the following US findings were retrospectively evaluated in 100 infants with cholestatic jaundice (BA, n = 46; non-BA, n = 54): length and morphology of the gallbladder, triangular cord thickness, hepatic artery and portal vein diameters, and visualization of the common bile duct. Logistic regression analyses were performed to determine the features that would be useful in predicting BA. Conditional inference tree analysis was used to generate a decision-making tree for classifying patients into the BA or non-BA groups. Multivariate logistic regression analysis showed that abnormal gallbladder morphology and greater triangular cord thickness were significant predictors of BA (p = 0.003 and 0.001; adjusted odds ratio: 345.6 and 65.6, respectively). In the decision-making tree using conditional inference tree analysis, gallbladder morphology and triangular cord thickness (optimal cutoff value of triangular cord thickness, 3.4 mm) were also selected as significant discriminators for differential diagnosis of BA, and gallbladder morphology was the first discriminator. The diagnostic performance of the decision-making tree was excellent, with sensitivity of 100% (46/46), specificity of 94.4% (51/54), and overall accuracy of 97% (97/100). Abnormal gallbladder morphology and greater triangular cord thickness (> 3.4 mm) were the most useful predictors of BA on US. We suggest that the gallbladder morphology should be evaluated first and that triangular cord thickness should be evaluated subsequently in cases with normal gallbladder morphology

    To compare hepatic gene expression during the development of experimental biliary atresia (BA) in two different mouse strains. Balb/c mice and C57Black/6 (Black/6) mice were infected with rhesus rotavirus (RRV) postpartum, clinical signs of BA and survival were noted. Liver sections were assessed for cluster of differentiation antigen (CD) 3, CD4 and CD8 expression, and the hepatic virus load was determined. Second, mice of both strains were sacrificed three days after infection. Isolated hepatic RNA was subjected to gene expression analysis using Affymetrix Gene Chip MOE 430 2.0. The incidence of BA was significantly lower in Black/6 mice compared to Balb/c mice (13.5% vs. 67%, P < 0.05). The mean virus titers were higher in mice with BA compared to mice without BA. Different gene profiles three days after virus infection were noted, with differential expression of 201 genes, including those regulating apoptosis, nucleic acid binding, transport function and particularly the immune response (chemokine C-C motif ligand 2, toll-like receptor 3, CD antigen 14, chemokine (C-X-C motif) ligands 10 and 11). This correlated with a significant increase of CD4 positive cells only in Balb/c mice with BA compared to healthy mice (13.5 vs. 5.0; P < 0.05). Black/6 mice did not exhibit any significant increase of CD3 or CD4 leukocytes despite cholestasis. The different susceptibility to experimental BA was associated with an increase of CD4 T-cells in the liver of Balb/c mice, which is linked to different gene profiles at the onset of bile duct obstruction.

    Full Text Available Background: Biliary atresia (BA has been a challenge to surgeons worldwide. Beyond the revolutionary surgical technique popularised by Kasai, liver transplantation has added renewed hope in the long-term outcome. In Nigeria, where late presentation is very common, there is need to assess the long-term results of the treatment options available to us. Aim: We aimed to evaluate the presentation and management outcome of BA and the long-term survival of BA patients seen in our practice. Materials and Methods: Cases of BA seen between January 2007 and December 2011 in three tertiary health facilities in South East Nigeria were included. Data obtained included age at presentation, clinical features, treatment offered and age at the time of death. Analysis was with the SPSS 17.0. Results: Twenty four patients comprising 10 (41.7% males and 14 (58.3% females were included in the study. The mean age of presentation was 4.02 (±214 months; range 1.75-11.0 months. Fifteen (62.5% patients had surgery while 9 (37.5% received medical treatment only. The mean age at death was 14.2 (±8.1 months; range 2.5-30 months. Conclusion: BA poses a daunting challenge in our practice. Outcome of treatment is still discouraging. We identified late presentation, lack of facilities to make early diagnosis, lack of adequately trained manpower to manage these children and lack of post-operative care and support for patients as the major challenges in the management of BA children in our region.

    Recurrent cholangitis may aggravate cholestatic liver cirrhosis in biliary atresia (BA) after the Kasai operation. This pilot study aimed to investigate whether Lactobacillus casei rhamnosus has the prophylactic efficacy for recurrent cholangitis in comparison with the conventional neomycin prophylaxis. Twenty jaundice-free patients with BA ages 0 to 3 years who underwent a Kasai operation were enrolled and randomized into 2 groups with 10 patients each: neomycin (25 mg · kg · day for 4 days/wk) and L casei rhamnosus (8 × 10 colony-forming unit per day) groups. The treatment duration was 6 months. Bacterial stool cultures were performed before treatment and 1, 3, and 6 months after starting treatment. In addition, 10 patients with BA with similar status but without prophylaxis served as the historical control group. In the Lactobacillus group, 2 patients (20%, mean 0.03 ± 0.07 episodes per month) developed cholangitis during the study period, with the same frequency as in the neomycin group and significantly lower than that in the control group (80%, P = 0.005, mean 0.22 ± 0.16 episodes per month). The mean change in body weight z score during the 6 months in the Lactobacillus group was 0.97 ± 0.59, which was significantly better than that in the control group (-0.01 ± 0.79, P = 0.006). In bacterial stool cultures, the Lactobacillus and Escherichia coli populations significantly increased and decreased, respectively, in the Lactobacillus group. The use of L casei rhamnosus was as effective as neomycin in preventing cholangitis in patients with BA who underwent Kasai operation, and therefore could be considered as a potential alternative prophylactic regimen.

    Biliary atresia (BA), a cholangiopathy of unknown etiology is associated with intrahepatic mononuclear cell infiltrate. An abnormal reaction to viral exposure has been hypothesized in some cases. We aimed to investigate the nature of the CD4+ hepatic infiltrate in defined clinical variants of BA by quantification of inflammatory cell components. Liver biopsies of infants obtained at Kasai portoenterostomy (KPE) were stained immunohistochemically using monoclonal antibodies to Tbet, GATA-3, FOXP3 and interleukin (IL) 17, identifying Th-1, Th-2, Tregs and Th-17 cells respectively. T cells were counted with the aid of a graticule. Data are reported as median (range) of cells per high-power-field (×400) and compared using nonparametric statistical tests with P≤0.05 regarded as significant. Liver biopsies from BA (n=37) and age-matched cholestatic controls (e.g. alpha-1-anti trypsin deficiency, Alagilles syndrome, n=12) were investigated. BA infants were divided into three groups: cytomegalovirus IgM +ve (CMV; n=9); BA splenic malformation (BASM; n=9) and isolated BA (IBA; n=19). All T-cell subsets were present in the portal tracts, with an overrepresentation of Th-1 (PTh-17 (PTh-2 (P=0.94) or Tregs (P=0.15), compared to controls. Th-1 cells predominated in the CMV group; (18 [7-37] vs. 3 [0-14] [BASM] and vs. 5 [3-23] [IBA]; PTh-17 cells. The degree of Th-1 cell infiltrate inversely correlated with platelet count (rS=-0.49; PTh-17 cells were fewer (6 [2-11] vs. 11 [8-20]; P=0.02) in infants who cleared their jaundice (n=15, Th-17 cells infiltrate the liver in BA and are associated with a worse surgical outcome; a Th-1 profile predominates in CMV-associated BA.

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

    We report an 8-month-old girl with portal hypertension secondary to biliary atresia. The decision to treat with TIPS was made at the age of 8 months due to recurrent variceal bleeding. The procedure was carried out with a 6-mm bare stent due to her small size. Radiological follow-up with Doppler US showed gradual stenosis and finally occlusion of the stent 80 days after implantation. Revision was performed with placement of an additional 6-mm expanded polytetrafluoroethylene (e-PTFE) stent-graft that had remained patent for 9 months, proving that in small children with a portal vein diameter less than 8 mm, the combination of a bare stent and stent-graft can provide excellent results.

    To assess neurodevelopmental outcomes among participants with biliary atresia with their native liver at ages 12 months (group 1) and 24 months (group 2), and to evaluate variables predictive of neurodevelopmental impairment. Participants enrolled in a prospective, longitudinal, multicenter study underwent neurodevelopmental testing with either the Bayley Scales of Infant Development, 2nd edition, or Bayley Scales of Infant and Toddler Development, 3rd edition. Scores (normative mean = 100 ± 15) were categorized as ≥100, 85-99, and Development, 2nd edition, or Bayley Scales of Infant and Toddler Development, 3rd edition, scales) was analyzed using logistic regression. There were 148 children who completed 217 Bayley Scales of Infant and Toddler Development, 3rd edition, examinations (group 1, n = 132; group 2, n = 85). Neurodevelopmental score distributions significantly shifted downward compared with test norms at 1 and 2 years of age. Multivariate analysis identified ascites (OR, 3.17; P = .01) and low length z-scores at time of testing (OR, 0.70; P cognitive/language impairment at 1 year of age. An unsuccessful hepatoportoenterostomy was predictive of both physical/motor (OR, 4.88; P cognitive/language impairment (OR, 4.76; P = .02) at 2 years of age. Participants with biliary atresia surviving with native livers after hepatoportoenterostomy are at increased risk for neurodevelopmental delays at 12 and 24 months of age. Those with unsuccessful hepatoportoenterostomy are >4 times more likely to have neurodevelopmental impairment compared with those with successful hepatoportoenterostomy. Growth delays and/or complications indicating advanced liver disease should alert clinicians to the risk for neurodevelopmental delays, and expedite appropriate interventions.

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

    Aim: To investigate the prognostic relevance of hepatobiliary scintigraphy (HBS) in newborns suffering from biliary atresia (BA) for establishing the primary diagnosis and in the postoperative follow-up after portoenterostomy (Kasai). Methods: Twenty newborns with direct hyperbilirubinemia and 6 children after operative treatment of BA (Kasai) underwent HBS with Tc-99m-DEIDA. In patients without intestinal drainage, hepatocellular extraction was estimated visually and calculated semiquantitatively by means of liver/heart-ratio 5 min p.i. Results: 10/20 patients with hyperbilirubinemia did not display biliary drainage; 6 had BA, 3 intrahepatic hypoplasia, and one showed a bile plug syndrom. 4/6 with BA but none of the 4 children with diagnoses other than BA presented with a good extraction. All of the 4 children with BA, who had either pre- or postoperatively a bad extraction, needed liver transplantation due to liver failure. Both of the two newborns with BA and favourable outcome after Kasai had a good extraction in the preoperative HBS and demonstrated good intestinal drainage in the postoperative scan. Conclusion: HBS rules out BA with high accuracy by demonstrating drainage of bile into the intestine. In newborns without drainage a good extraction favours the diagnosis of BA. In newborns with BA a bad extraction seems to indicate a poor postoperative prognosis after Kasai operation. HBS might therefore help to select those children who will not benefit from portoenterostomy. Postoperatively, HBS can easily and quickly confirm the successful hepatobiliary anastomosis by demonstrating biliary drainage into the intestine. (orig.) [de

    Rotavirus infection is one of the most common causes of diarrheal illness in humans. In neonatal mice, rhesus rotavirus (RRV) can induce biliary atresia (BA), a disease resulting in inflammatory obstruction of the extrahepatic biliary tract and intrahepatic bile ducts. We previously showed that the amino acid arginine (R) within the sequence SRL (amino acids 445 to 447) in the RRV VP4 protein is required for viral binding and entry into biliary epithelial cells. To determine if this single amino acid (R) influences the pathogenicity of the virus, we generated a recombinant virus with a single amino acid mutation at this site through a reverse genetics system. We demonstrated that the RRV mutant (RRV VP4-R446G ) produced less symptomatology and replicated to lower titers both in vivo and in vitro than those seen with wild-type RRV, with reduced binding in cholangiocytes. Our results demonstrate that a single amino acid change in the RRV VP4 gene influences cholangiocyte tropism and reduces pathogenicity in mice. IMPORTANCE Rotavirus is the leading cause of diarrhea in humans. Rhesus rotavirus (RRV) can also lead to biliary atresia (a neonatal human disease) in mice. We developed a reverse genetics system to create a mutant of RRV (RRV VP4-R446G ) with a single amino acid change in the VP4 protein compared to that of wild-type RRV. In vitro , the mutant virus had reduced binding and infectivity in cholangiocytes. In vivo , it produced fewer symptoms and lower mortality in neonatal mice, resulting in an attenuated form of biliary atresia. Copyright © 2017 American Society for Microbiology.

    Biliary atresia (BA) is a pediatric cholangiopathy with unknown etiology occurring in isolated and syndromic forms. Laterality defects affecting the cardiovascular and gastrointestinal systems are the most common features present in syndromic BA. Most cases are sporadic, although reports of familial cases have led to the hypothesis of genetic susceptibility in some patients. We identified a child with BA, malrotation, and interrupted inferior vena cava whose father presented with situs inversus, polysplenia, panhypopituitarism, and mildly dysmorphic facial features. Chromosomal microarray analysis demonstrated a 277 kb heterozygous deletion on chromosome 20, which included a single gene, FOXA2, in the proband and her father. This deletion was confirmed to be de novo in the father. The proband and her father share a common diagnosis of heterotaxy, but they also each presented with a variety of other issues. Further genetic screening revealed that the proband carried an additional protein-altering polymorphism (rs1904589; p.His165Arg) in the NODAL gene that is not present in the father, and this variant has been shown to decrease expression of the gene. As FOXA2 can be a regulator of NODAL expression, we propose that haploinsufficiency for FOXA2 combined with a decreased expression of NODAL is the likely cause for syndromic BA in this proband. © 2015 WILEY PERIODICALS, INC.

    Mac-2 Binding Protein Glycosylation Isomer (M2BPGi) is a novel fibrosis marker. We examined the ability of M2BPGi to predict liver fibrosis in patients with biliary atresia. Sixty-four patients who underwent living donor liver transplantation (LDLT) were included [median age, 1.1 years (range 0.4-16.0), male 16 patients (25.0 %)]. We examined M2BPGi levels in serum obtained the day before LDLT, and we compared the value of the preoperative M2BPGi levels with the histological evaluation of fibrosis using the METAVIR fibrosis score. Subsequently, we assessed the ability of M2BPGi levels to predict fibrosis. The median M2BPGi level in patients with BA was 6.02 (range, 0.36-20.0), and 0, 1, 1, 11, and 51 patients had METAVIR fibrosis scores of F0, F1, F2, F3, and F4, respectively. In patients with F4 fibrosis, the median M2BPGi level was 6.88 (quartile; 5.235, 12.10), significantly higher than that in patients with F3 fibrosis who had a median level of 2.42 (quartile; 1.93, 2.895, p F4 fibrosis. M2BPGi is a novel fibrosis marker for evaluating the status of the liver in patients with BA, especially when predicting grade F4 fibrosis.

    Full Text Available Hepatopulmonary syndrome (HPS is a serious complication of end-stage liver disease, which is characterized by hypoxia, intrapulmonary vascular dilatation, and liver cirrhosis. Liver transplantation (LT is the only curative treatment modality for patients with HPS. However, morbidity and mortality after LT, especially in cases of severe HPS, remain high. This case report describes a patient with typical findings of an extracardiac pulmonary arteriovenous shunt on contrast-enhanced transesophageal echocardiography (TEE, and clubbing fingers, who had complete correction of HPS by deceased donor LT. The patient was a 16-year-old female who was born with biliary atresia and underwent porto-enterostomy on the 55th day after birth. She had been suffered from progressive liver failure with dyspnea, clubbing fingers, and cyanosis. Preoperative arterial blood gas analysis revealed severe hypoxia (arterial O2 tension of 54.5 mmHg and O2 saturation of 84.2%. Contrast-enhanced TEE revealed an extracardiac right-to-left shunt, which suggested an intrapulmonary arteriovenous shunt. The patient recovered successfully after LT, not only with respect to physical parameters but also for pychosocial activity, including school performance, during the 30-month follow-up period.

    Aim: To establish the risks of developing of hepatic tumours and to investigate their clinical and imaging findings in children with biliary atresia (BA) after Kasai portoenterostomy (Kasai). Materials and methods: Among 157 children who had undergone Kasai for BA over an 18 year period, patients who had newly developed hepatic tumours were identified. Patient demographics, clinical features, and imaging findings were retrospectively reviewed. Results: Three male and 10 female patients (mean age 3.9 years) all (8%, of 157) had single hepatic tumours, which were confirmed in 10 explanted and three non-explanted livers. Ten (77%) were benign and three (23%) were malignant. Of the benign hepatic tumours, focal nodular hyperplasia (FNH; n = 6) was the most common, followed by regenerative nodules (n = 3) and adenoma (n = 1). All FNH appeared in young children <1 year of age and showed a subcapsular location, bulging contour, and lack of central scar. Malignant tumours included two hepatocellular carcinomas and one cholangiocarcinoma. Conclusion: Hepatic tumours developed in approximately 8% of children with BA after Kasai. Although benign tumours, including FNHs and regenerative nodules, were more common than malignant tumours, screening with alpha-foetoprotein (AFP) levels and regular imaging studies are the mainstay of malignant tumour detection

    Full Text Available BACKGROUND: The progression of hepatic fibrosis may result in decompensated hepatic failure with cirrhosis, liver related events (LRE such as ascites, variceal bleeding, and death after successful and timely Kasai hepatoportoenterostomy (HPE in biliary atresia. The aim of this study is to suggest clinical benefit of the liver stiffness measurement (LSM using transient elastography at 3 months after the Kasai operation to predict LRE. METHODS: Between January 2007 and December 2011, 69 eligible biliary atresia patients who underwent Kasai HPE and performed transient elastography before and 3 months after HPE were included. The occurrences of LRE were analyzed for all patients. All patients were divided into 2 groups (with and without LRE for comparison. Multivariate analysis was used to detect the independent risk factors of LRE. The area under the receiver operation characteristics curve (AUROC was used to establish the LSM optimal cutoff value of 3 months after Kasai operation in predicting LRE. RESULTS: LSM value, aminotransferase, albumin, bilirubin, and PT-INR significantly differed among the two groups. Multivariate analysis demonstrated LSM value as the most powerful independent factor of the development of LRE. The cut-off value of 19.9 kPa was calculated to be optimal for predicting LRE development with total sensitivity and specificity of 1.804. AUROC resulted in 0.943, with sensitivity of 85.3% and specificity of 95.2%. CONCLUSIONS: The LSM value of 3 months after Kasai HPE can be a useful predictor of LRE development.

    Hepatic apparent diffusion coefficient (ADC) values and ADC-related indices were correlated with the Mayo risk score for primary biliary cirrhosis (MRSPBC) and METAVIR scores of liver specimens to determine the clinical and pathological significance of diffusion-weighted magnetic resonance imaging (DWMRI). Thirty-two patients with biliary atresia (BA; mean age 461 days, range 11-4616 days) received magnetic resonance examinations from March 2009 to August 2013. A free-breathing DWMRI sequence was performed with the single-shot echo-planar imaging technique with b = 0 and 500 s/mm 2 in all 32 BA patients and 24 controls. We used the ordinal logistic regression test and Spearman rank correlation test to analyse the relationships between the MRSPBC and METAVIR fibrosis scores and right liver-to-psoas ADC ratios (LTPARs). BA patients had significantly lower LTPARs in both hepatic lobes than controls (p < 0.01). Right LTPARs, showing moderate intraobserver agreement (intraclass correlation coefficient = 0.736) and interobserver reliability (intraclass correlation coefficient = 0.659), were negatively correlated with MRSPBC and METAVIR fibrosis scores (R 2 = 0.398, p = 0.024 and R 2 = 0.628, p < 0.001, respectively). Right LTPARs may be used for long-term follow-up of cirrhosis severity in BA patients. (orig.)

    histopathology, in isolation or in combination, for diagnostic differentiation between biliary atresia and intrahepatic cholestasis. METHODS: This was a retrospective study carried out between January 1990 and December 2004. Fifty-one cases of biliary atresia and 45 of intrahepatic cholestasis were analyzed. Histopathology was performed blind by a pathologist. The triangular cord sign was identified in ultrasound reports as the only diagnostic sign of biliary atresia. Sensitivity, specificity and accuracy were calculated for the triangular cord sign and histology both in isolation and in combination. The gold standard for diagnosis of biliary atresia was the appearance of the extrahepatic biliary tree via laparotomy. RESULTS: The triangular cord sign alone had sensitivity of 49%, specificity of 100% and accuracy of 72.5%. Histopathology compatible with extrahepatic biliary obstruction alone had 90.2% sensitivity, 84.6% specificity and 87.8% accuracy. The triangular cord sign and histopathology in isolation or combination resulted in sensitivity of 93.2%, specificity of 85.7% and accuracy of 90.3%. CONCLUSIONS: Finding the triangular cord sign on ultrasound is an indication for laparotomy. If the triangular cord sign is negative, liver biopsy is indicated; if histopathology reveals signs of biliary atresia, explorative laparotomy is indicated. In cases where the triangular cord sign is absent and histopathology indicates neonatal hepatitis or other intrahepatic cholestasis, clinical treatment or observation are recommended in accordance with the diagnosis.

    Full Text Available ObjectiveTo compared the prognosis between infants with biliary atresia (BA who underwent living donor liver transplantation (LDLT during 2006-2009 and 2010-2012 in the Department of Liver Surgery, Renji Hospital, Shanghai Jiaotong University School of Medicine and to evaluate the prognos is of LDLT performed during different periods. MethodsA retrospective analysis was performed on the clinical data of 101 infants with BA who underwent LDLT from October 2006 to December 2012. These patients were divided into 2006-2009 group and 2010-2012 group according to the year the procedure was performed. The two groups were compared in terms of preoperative general data, intraoperative status, and treatment outcome. The Kaplan-Meier method was used for survival analysis; measurement data were analyzed by t test, and enumeration data were analyzed by Fisher exact probability test and chi-square test. ResultsThe preoperative general data showed no significant difference between the two groups. Compared with the 2006-2009 group, the 2010-2012 group had significantly less intraoperative blood loss (t=2.05, P=0.04, a significantly shorter cold ischemia time of donor liver (t=3.25, P<0.01, and significantly lower incidence of postoperative biliary complications (χ2=4.27, P=0.04, pulmonary infection (χ2=4.47, P=0.03, and acute rejection (P=0.03. The 2010-2012 group had significantly improved survival compared with the 2006-2009 group; the 1 and 2 year cumulative survival rates for the 2010-2012 group were 884% and 88.4%, respectively, versus 84.4% and 75% for the 2006-2009 group. ConclusionThe development of surgical techniques, improvement in perioperative management, and standardized follow-up can significantly increase the success rate of surgery and survival rate and reduce postoperative complications in BA patients.

    Hepatoportoenterostomy (HPE) with the Kasai procedure is the treatment of choice for biliary atresia (BA) as the initial surgery. However, the appropriate level of dissection level of the fibrous cone (FC) of the porta hepatis (PH) is frequently unclear, and the procedure sometimes results in unsuccessful outcomes. Recently, indocyanine green near-infrared fluorescence imaging (ICG-FCG) has been developed as a form of real-time cholangiography. We applied this technique in five patients with BA to visualize the biliary flow at the PH intraoperatively. ICG was injected intravenously the day before surgery as the liver function test, and the liver was observed with a near-infrared camera system during the operation while the patient's feces was also observed. In all patients, the whole liver fluoresced diffusely with ICG-containing stagnant bile, whereas no extrahepatic structures fluoresced. The findings of the ICG fluorescence pattern of the PH after dissection of the FC were classified into three types: spotty fluorescence, one patient; diffuse weak fluorescence, three patients; and diffuse strong fluorescence, one patient. In all five patients, the feces evacuated after HPE showed distinct fluorescent spots, although that obtained before surgery showed no fluorescence. One patient with diffuse strong fluorescence who did not achieve JF underwent living related liver transplantation six months after the initial HPE procedure. Four patients, including three cases involving diffuse weak fluorescence and one case involving spotty fluorescence showed weak fluorescence compared to that of the surrounding liver surface. We were able to detect the presence of bile excretion at the time of HPE intraoperatively and successfully evaluated the extent of bile excretion using this new technique. Furthermore, the ICG-FCG findings may provide information leading to a new classification and potentially function as an indicator predicting the clinical outcomes after HPE.

    Two polymorphisms, rs755622 and rs5844572, in the promoter region of the macrophage migration inhibitory factor (MIF) gene influence the basal and/or induced transcriptional activity and have been linked to several inflammatory and autoimmune diseases. The aim of this study was to investigate the association between these two polymorphisms and disease susceptibility in patients with biliary atresia (BA). Allele frequencies of rs755622 and rs5844572 were assessed in 60 Egyptian infants with a confirmed diagnosis of BA. DNA was extracted from archival material. For the rs755622, samples were tested using Taqman real-time PCR, and for the rs5844572, samples were tested using fluorescence-based genotyping. The allele frequency in the general population was assessed in 141 healthy adults from the same geographical location. No statistical differences were observed in the allele frequencies of either rs755622 or rs5844572 between BA patients and controls. The homozygous and heterozygous short repeats (5/5, or 5/X) of rs5844572 were observed more frequently (16/28, 57.1%) in BA patients with mild to moderate fibrosis compared with those with marked fibrosis (10/32, 31.3%). The difference was statistically significant (P  =  0.032). In conclusion, we observed no association between MIF rs755622 and rs5844572 polymorphisms and susceptibility to BA; however, the rs5844572 could be linked to the rate of progression of the disease and extent of fibrosis. © 2017 John Wiley & Sons Ltd/University College London.

    Biliary atresia (BA) is a rare disease in infants, with unknown mechanisms of pathogenesis. It is characterized by hepatobiliary inflammatory, progressive destruction of the biliary system leading to liver fibrosis, and deterioration of liver function. Interleukin (IL) 17A promotes inflammatory and autoimmune processes. We studied the role of IL17A and cells that produce this cytokine in a mouse model of BA and in hepatic biopsy samples from infants with BA. We obtained peripheral blood and liver tissue specimens from 20 patients with BA, collected at the time of Kasai portoenterostomy, along with liver biopsies from infants without BA (controls). The tissue samples were analyzed by reverse transcription quantitative polymerase chain reaction (PCR), in situ PCR, and flow cytometry analyses. BA was induced in balb/cAnNCrl mice by rhesus rotavirus infection; uninfected mice were used as controls. Liver tissues were collected from mice and analyzed histologically and by reverse transcriptase PCR; leukocytes were isolated, stimulated, and analyzed by flow cytometry and PCR analyses. Some mice were given 3 intraperitoneal injections of a monoclonal antibody against IL17 or an isotype antibody (control). Livers from rhesus rota virus-infected mice with BA had 7-fold more Il17a messenger RNA than control mice (P = .02). γδ T cells were the exclusive source of IL17; no T-helper 17 cells were detected in livers of mice with BA. The increased number of IL17a-positive γδ T cells liver tissues of mice with BA was associated with increased levels of IL17A, IL17F, retinoid-orphan-receptor C, C-C chemokine receptor 6, and the IL23 receptor. Mice that were developing BA and given antibodies against IL17 had lower levels of liver inflammation and mean serum levels of bilirubin than mice receiving control antibodies (191 μmol/L vs 78 μmol/L, P = .002). Liver tissues from patients with BA had 4.6-fold higher levels of IL17 messenger RNA than control liver tissues (P = .02

    Regulatory T cells (Tregs) and CD4 + T helper (Th) cells have important roles in bile duct injury of biliary atresia (BA). However, their impacts on liver fibrosis are undefined. Between 2013 and 2016, 146 patients with various stages of BA were enrolled in this study. Peripheral blood, liver biopsy and lymph node samples were collected. Flow cytometry, magnetic cell sorting and immunostaining were used to characterize lymphocytes from BA patients. Deficiency of Tregs was observed along with increased Th1, Th2 and Th17 frequencies in the peripheral blood and livers of BA patients. The levels of peripheral and intrahepatic Th1 cells positively correlated with the stage of liver fibrosis. Furthermore, Th1 cells were located in close proximity to activated hepatic stellate cells (HSCs) and areas of fibrosis in BA livers. In culture, Th1 cells accelerated the proliferation and secretion of profibrogenic markers of HSCs through the IFN-γ/STAT1 pathway. Of note, Tregs blocked the Th1-stimulated effects on HSCs by inhibiting Th1-induced activation of STAT1. Consistent with the results of in vitro study, intrahepatic IFN-γ/STAT1 levels increased in relation to the severity of liver fibrosis in BA patients, and the altered balance between MMP2 and TIMP1 expressions in livers may contribute to increased deposition of extracellular matrix and fibrosis. Finally, to identify the effects of Th1 cells on Tregs, we demonstrated that Th1 cells upregulated the proportion of aTreg cells by secreting IFN-γ cytokine. Thus, aberrant Th1 immune responses in BA promote the proliferation and secretion of HSCs through the IFN-γ/STAT1 pathway. The regulation of HSCs by the interactions between Tregs and Th1 cells might be part of the mechanism underlying progressive liver fibrosis and may be a suitable target for therapy.

    Aim: To investigate the prognostic relevance of hepatobiliary scintigraphy (HBS) in newborns suffering from biliary atresia (BA) for establishing the primary diagnosis and in the postoperative follow-up after portoenterostomy (Kasai). Methods: Twenty newborns with direct hyperbilirubinemia and 6 children after operative treatment of BA (Kasai) underwent HBS with Tc-99m-DEIDA. In patients without intestinal drainage, hepatocellular extraction was estimated visually and calculated semiquantitatively by means of liver/heart-ratio 5 min p.i. Results: 10/20 patients with hyperbilirubinemia did not display biliary drainage; 6 had BA, 3 intrahepatic hypoplasia, and one showed a bile plug syndrom. 4/6 with BA but none of the 4 children with diagnoses other than BA presented with a good extraction. All of the 4 children with BA, who had either pre- or postoperatively a bad extraction, needed liver transplantation due to liver failure. Both of the two newborns with BA and favourable outcome after Kasai had a good extraction in the preoperative HBS and demonstrated good intestinal drainage in the postoperative scan. Conclusion: HBS rules out BA with high accuracy by demonstrating drainage of bile into the intestine. In newborns without drainage a good extraction favours the diagnosis of BA. In newborns with BA a bad extraction seems to indicate a poor postoperative prognosis after Kasai operation. HBS might therefore help to select those children who will not benefit from portoenterostomy. Postoperatively, HBS can easily and quickly confirm the successful hepatobiliary anastomosis by demonstrating biliary drainage into the intestine. (orig.)

    Progressive hepatic fibrosis (HF) is a prominent feature of biliary atresia (BA), the most common indication for liver transplantation (LT) in children. Despite its importance in BA, HF is not evaluated in routine patient care because the invasiveness of liver biopsy makes histologic monitoring of fibrosis unfeasible. Therefore, the identification of noninvasive markers to assess HF is desirable especially in children. The main goal of this pilot project was to establish an investigational framework correlating hepatic expression of fibrogenic markers with routine blood tests in BA. Using liver explants from patients with BA (n = 26), immune-expression of connective tissue growth factor (CTGF), a key fibrogenic cytokine was determined using horseradish-labeled antibodies. Expression intensities of lobular (L-CTGF) and portal (P-CTGF) CTGF were determined by using ImageJ software. These CTGF intensities were correlated with blood tests performed at the time of LT. Correlation coefficients were determined for each blood test variable versus mean L-CTGF and P-CTGF expression intensities. A P-value of less than 0.05 was considered statistically significant. All patients had end-stage liver disease and persistent cholestasis at the time of LT. Kendall tau (τ) rank correlation coefficient for L-CTGF and white blood cell (WBC) was inversed (-0.52; P ≤ 0.02). Similar but statistically nonsignificant inverse relationships were noted between L-CTGF and prothrombin time (PT) (-0.15; P ≤ 0.4), international normalized ratio (INR) (-0.14; P ≤ 0.5), and platelet count (-0.36; P ≤ 0.09). Inversed (τ) rank correlation coefficients were also evident between P-CTGF expression and gamma-glutamyl transpeptidase (GGT), PT, INR, and platelet count. Pearson correlation coefficients for combinational analysis of standardized total bilirubin (TB), alkaline phosphatase, GGT, and platelet count with L-CTGF (0.33; P = 0.3) and P-CTGF (0.06; P = 0.8), were not significant.

  9. Biliary Innate Immunity: Function and Modulation

    Directory of Open Access Journals (Sweden)

    Kenichi Harada

    2010-01-01

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

    Biliary atresia continues to be a serious and relatively rare disease (1/50,000 newborns) and whose long-term prognosis has changed drastically since the appearance of liver transplant (LT) as a therapeutic weapon. The combination of two factors, early diagnosis and correct application of Kasai's surgical technique, is essential to obtain acceptable results and sufficient biliary drainage allowing the children to overcome the critical 7 kg barrier and place them in the lesser morbi-mortality range in relation to a possible LT. But we must keep in mind that despite its critics, Kasai's technique can guarantee, both in our own experience and in the literature, ten years survival percentages over 50% with correct hepatic function, as well as clinical normality and a quality of life clearly superior to first years post-LT. We present the evolution of a group of 20 patients affected with biliary atresia, diagnosed in our center since 1985, the year when pediatric LT began to be used as a therapeutic procedure in this country. We valued the age of intervention, technique, immediate and long-term results and the evolution and necessity of LT. All 20 patients were analyzed individually, and they currently have an age range from 2-14 years and were all operated by Kasai's technique. We classified the patients as having good, regular or poor results with regards to biliary flow, normalization of billirubin levels and clinical evolution. Sixteen patients presented biliary flow of such an extent that 14 of them, classified as good, completely normalized the billirubin levels. Two others, presently aged 14 and 8 years respectively, present average levels of 2.5-5.5 mg/100 ml and are classified as regular in a situation of advisable transplant, although with an acceptable hepatic function. Only one case, the first in the poor group, did not initially present biliary elimination and died at age six months while on the waiting list. Three other cases in the same group presented

    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)

    Bypass of the atretic duodenal segment through an anomalous pancreatic ductal system is a rare anomaly described in the literature in only a handful of cases. This case report highlights the importance of considering duodenal atresia and pancreaticobiliary enteric bypass in the differential diagnosis of neonates presenting with partial duodenal obstruction. On ultrasound, the presence of gas in the biliary tree or pancreatic duct should alert the physician to the possibility of duodenal atresia with congenital pancreaticobiliary duct anomalies that allow for bypass of enteric contents, including air, into more distal bowel, thereby creating a gas pattern aptly described as double bubble with distal gas.

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

    Congenital choanal atresia is a rare abnormality characterized by unilateral or bilateral lack of patency of the posterior end of the nasal cavity. With an incidence of 1:5000 to 1:8000 births, it is twice as prevalent in females as it is in males. Surgical procedures aim to provide adequate functional choanal patency and a low rate of restenosis, avoid harm to any structure in development, enable shorter surgery and hospitalization times, and minimize morbidity and mortality. To evaluate the effectiveness and safety of the available surgical techniques for the treatment of congenital choanal atresia in patients with unilateral and bilateral atresia. We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ISRCTN and additional sources for published and unpublished trials. The date of the search was 31 January 2011. We planned to include parallel randomized or quasi-randomized controlled trials testing surgical approaches for the treatment of congenital atresia (irrespective of gender and age) that evaluated normal/adequate respiratory function (self reported or preserved nasal airway) and restenosis as the main primary outcomes. We did not consider reoperation and non-congenital atresia (e.g. traumatic, iatrogenic atresias) for inclusion. Three review authors independently assessed the titles and abstracts of the identified articles to determine potential relevance. For dichotomous and continuous variables, we planned to calculate risk ratios (relative risks; RR) and mean differences (MD) with 95% confidence intervals (CI), respectively. We planned to use the random-effects model since we were expecting substantial clinical and methodological heterogeneity. No randomized controlled trials were identified. From the 120 reports retrieved using our search strategy, 46 primary studies had the

    Full Text Available We encountered a rare case of gastroschisis associated with jejunal atresia and colonic atresia. In our case, the jejunal atresia was not discovered for 27 days after the initial abdominal wall closure. The colonic atresia was not discovered for 48 days after initial repair of the gastroschisis secondary to the rarity of the disorder. Both types of atresia were repaired with primary hand-sewn anastomoses. Other than the prolonged parenteral nutrition and hyperbilirubinemia, our patient did very well throughout his hospital course. Based on our case presentation, small bowel atresia and colonic atresia must be considered in patients who undergo abdominal wall closure for gastroschisis with prolonged symptoms suggestive of bowel obstruction. Our case report also demonstrates primary enteric anastomosis as a safe, well-tolerated surgical option for patients with types of intestinal atresia.

    Biliary atresia (BA) is the most common cause of liver transplantation in children. The earlier the treatment is done, the better the prognosis. The aim is to evaluate the impact of late diagnosis in children with BA, including the histopathological findings and success rate of biliary drainage in patients submitted to hepatic portoenterostomy (HPE). A retrospective study of cases of BA in the Department of Pediatric Surgery, Federal University of São Paulo (UNIFESP) between 1998-2011. We found 63 cases of BA; of these, 42 underwent HPE and 21 were referred for liver transplantation. Clinic and pathologic data were evaluated. The HPE was performed with a mean age of 86.5 days, with 16.6% having the operation at 60 days or earlier; 59.2% between 61 and 90 days; and 23.8% after 90 days. Successful biliary drainage occurred in 31% of surgeries, Mean days when HPE drained was 69.1 days, and 94.3 days when the surgery did not drain (P = .05). All patients who were successfully drained, did not have grade IV fibrosis on histology. In cases in which surgery was performed after 60 days that had not drained, 25% had grade IV fibrosis on biopsy (P = .0469). The age of HPE relates to better prognosis of the disease. It was found that the rate of grade IV fibrosis is higher in no drainage patients. All patients with grade IV fibrosis had no biliary drainage. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Background/Purpose. Kimura's diamond-shaped-duodenoduodenostomy (DSD is a known technique for the correction of congenital intrinsic duodenal obstruction. We present a modification of the technique and review the advantages of this new technique. Methods. From 1992 to 2006, 14 newborns were treated for duodenal atresia. We inverted the direction of the duodenal incisions: a longitudinal incision was made in the proximal duodenum while the distal was opened by transverse incision. Results. Our “inverted-diamond-shaped-duodenoduodenostomy” (i-DSD allowed postoperative oral feeding to start on days 2 to 3, peripheral intravenous fluids discontinuity on days 3 to 8 (median values 3.6; time to achieve full oral feeds on days 8 to 12 (median values 9.4; the length of hospitalisation ranged from 10 and 14 days (median value 11.2. No complications related to the anastomosis, by Viz leakage, dehiscence, biliary stasis, or stenosis were observed. Conclusions. The i-DSD provides a safe procedure to protect the ampulla of Vater from injury and avoids any formation of a blind loop. The results show that patients who have i-DSD achieve full oral feeds in a very short time period and, consequently, the length of hospitalisation is also significantly reduced.

Windsock deformity has not been reported in rectal atresia especially, having been missed for 2 years. A 2-year-old girl reported only a severe constipation despite having a 1.5-cm anal canal in rectal examination with scanty discharge. She underwent loop colostomy and loopogram, which showed a wind sock deformity of rectum with mega colon. The patient underwent abdominoperineal pull-through with good result and follow-up. This is the first case of the wind sock deformity in rectal atresia being reported after 2 years of age. (author)

    Full Text Available Aortic atresia with an associated ventricular septal defect and adequate sized left ventricle is extremely rare. We present two cases in which an alternate diagnosis was suggested on echocardiography because the hypoplastic aortic trunk was missed due to its small caliber. The final diagnosis was, however, clinched on dual source computed tomography, which not only showed the thin aortic trunk but also clearly depicted the coronary artery origins from the hypoplastic aortic root. To the best of our knowledge, use of multi-detector computed tomography in aortic atresia with well developed left ventricle has not been reported in literature till date.

    Full Text Available We describe herein a case of unilateral pulmonary agenesis (PA with oesophageal atresia (EA/tracheoesophageal fistula (TEF that was diagnosed prenatally and repaired by esophagoesophagostomy with stable postoperative course. The patient was born at 34 weeks gestation, after ultrasonography at 22 weeks gestation showed possible right-sided diaphragmatic eventration or PA and EA was subsequently suspected due to hydramnios. The initial X-ray showed mediastinal shift to the right, and coil up sign of the nasogastric tube, without intracardiac anomaly. Immediately after the diagnosis of EA/TEF and unilateral PA on day 0, the patient was intubated in the operating room, and a gastrostomy tube was placed. After pulmonary status stabilized, at 4 days old, EA/TEF was repaired through a thoracotomy in the right 4 th intercostal space. The right main bronchus was noted to continue into the distal oesophagus; this fistula was ligated and divided, and a single-layer esophagoesophagostomy was performed under mild tension with one vertebral gap. The neonate was maintained on mechanical ventilation and gradually weaned to extubation at 7 days old. The postoperative course was uneventful, with the exception of prolonged jaundice that emerged at 3 months old. Laparoscopic cholangiography at that time excluded biliary atresia, and jaundice resolved spontaneously. The patient has not shown any respiratory symptoms or feeding difficulties as of the 12-month follow-up.

    Hereditary multiple intestinal atresia (HMIA) is an extremely uncommon cause of congenital bowel obstruction. The morbidity and mortality of this disease differ significantly from those of isolated intestinal atresias and non-hereditary forms of multiple intestinal atresia. Most notably, despite successful operative repairs of the atresias found in this disease, HMIA maintains a 100% lethality rate from continued post-operative intestinal failure and an associated severe immunodeficiency. We present a case of HMIA evaluated with fetal MRI and subsequently diagnosed by a combination of corroborative postnatal imaging with surgical exploration and pathological examination. (orig.)

    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

    2014-01-01

    Full Text Available Bronchial atresia is a rare pulmonary developmental anomaly characterized by the presence of a focal obliteration of a segmental or lobar bronchial lumen. The lung distal to the atretic bronchus is typically emphysematous along with the presence of mucus filled ectatic bronchi (mucoceles. BA is usually asymptomatic but pulmonary infections can rarely develop in the emphysematous lung distal to the atretic bronchus. We present a unique case of chronic pulmonary aspergillosis (CPA in a patient with BA with no evidence of immune dysfunction. The patient was treated initially with voriconazole and subsequently underwent surgical excision of the involved area. On follow-up, she has done extremely well with no evidence for recurrence. In summary, we describe the first case of chronic pulmonary aspergillosis in an immunocompetent patient with bronchial atresia.

    1985-01-01

    A study group of 160 index patients with isolated esophageal atresia, a control group of 160 matched healthy controls, and the first-degree relatives of patients and controls were examined; epidemiological, family planning, teratological, and genetic data were obtained by personal interview in the study and control groups. One half of the index patients were male. Intrauterine growth retardation, a higher proportion of mothers under 19 or over 30 years of age, and less skilled professions of the parents were found in the study group. There were more extramarital conceptions, more pregnancies in spite of the use of contraceptive pills, and more delayed conceptions in index patients mothers. The teratogens studied did not have an obvious pathological effect here. The sib occurrence of isolated esophageal atresia was 0.43%, which did not correspond well to the expected figure of 1.34% based on the polygenic model.

    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

Using a conceptual framework developed...... by Axel Honneth, I suggest in this article that the cartoon crisis is part of an ongoing struggle for recognition in Denmark, through which the terms by which Muslims residing in Denmark are recognized as legitimate citizens/residents of Danish society are negotiated—and on which Muslims may recognize...... the demands of Danish majority society as legitimate. As much as the cartoon affair was an event that, as Palle Weis (2006) writes, “suddenly” ruptured Danish society in 2005, it was therefore also part of a process that continues to shape social actors and their relationships....

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

  2. Feeding Difficulties in Children with Esophageal Atresia.

    Mahoney, Lisa; Rosen, Rachel

    2016-06-01

    The current available literature evaluating feeding difficulties in children with esophageal atresia was reviewed. The published literature was searched through PubMed using a pre-defined search strategy. Feeding difficulties are commonly encountered in children and adults with repaired esophageal atresia [EA]. The mechanism for abnormal feeding includes both esophageal and oropharyngeal dysphagia. Esophageal dysphagia is commonly reported in patients with EA and causes include dysmotility, anatomic lesions, esophageal outlet obstruction and esophageal inflammation. Endoscopic evaluation, esophageal manometry and esophograms can be useful studies to evaluate for causes of esophageal dysphagia. Oropharyngeal dysfunction and aspiration are also important mechanisms for feeding difficulties in patients with EA. These patients often present with respiratory symptoms. Videofluoroscopic swallow study, salivagram, fiberoptic endoscopic evaluation of swallowing and high-resolution manometry can all be helpful tools to identify aspiration. Once diagnosed, management goals include reduction of aspiration during swallowing, reducing full column reflux into the oropharynx and continuation of oral feeding to maintain skills. We review specific strategies which can be used to reduce aspiration of gastric contents, including thickening feeds, changing feeding schedule, switching formula, trialing transpyloric feeds and fundoplication.

    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.

    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.

The most common diagnostic tools to evaluate esophageal dysphagia, such as upper barium study and manometry, aim to characterize anatomy and function of the esophageal body and the esophagogastric junction (EGJ). Using these technologies, a variety of pathological motor patterns have been identified in children with esophageal atresia. However, t...

  7. 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.

    Full Text Available OBJETIVO: Avaliar as características epidemiológicas, clínicas e prognósticas de crianças com atresia biliar. MÉTODOS: Dados sobre portoenterostomia, transplante hepático (TxH, idade no último seguimento e sobrevida foram coletados dos prontuários de pacientes acompanhados em seis centros no Brasil (1982-2008 e comparados em relação às décadas do procedimento cirúrgico. RESULTADOS: Dos 513 pacientes, 76,4% foram submetidos a portoenterostomia [idade: 60,0-94,7 (82,6±32,8 dias] e 46,6% foram submetidos a TxH. Em 69% dos casos, o TxH foi realizado após a portoenterostomia, enquanto em 31% dos casos o TxH foi realizado como cirurgia primária. Os pacientes da região Nordeste foram submetidos a portoenterostomia mais tardiamente do que as crianças das regiões Sul (p = 0,008 e Sudeste (p = 0,0012, embora, mesmo nas duas últimas regiões, a idade no momento da portoenterostomia tenha sido superior ao desejável. Ao longo das décadas, houve aumento progressivo do número de TxH realizados. A sobrevida global foi de 67,6%. A sobrevida aumentou nas últimas décadas (anos 1980 versus 1990, p = 0,002; anos 1980 versus 2000, p 90 dias, respectivamente. Os pacientes transplantados apresentaram taxas de sobrevida mais elevadas (88,3%. A sobrevida de 4 anos com fígado nativo foi de 36,8%, inversamente correlacionada à idade no momento da portoenterostomia (54, 33,3, 26,6% para 90 dias, respectivamente. CONCLUSÕES: Este estudo multicêntrico demonstrou que o encaminhamento tardio das crianças portadoras de atresia biliar ainda é um problema no Brasil, influenciando a sobrevida destes pacientes. Estratégias que proporcionam o encaminhamento precoce estão sendo desenvolvidas com o objetivo de reduzir a necessidade de transplante hepático nos primeiros anos de vida.

  9. Benign Biliary Strictures and Leaks.

    Devière, Jacques

    2015-10-01

    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.

    Conclusion: In very proximal high atresia, the extent of tapering is limited by the proximity of the ligament of Treitz. Duodenal derotation provides better access to the high atresia. The results of this limited experience suggest that the DDETJ procedure could provide an alternative therapy in patients with high jejunal atresia.

  12. Intestinal smooth muscle response to chronic obstruction : possible applications in jejunoileal atresia.

    Hyperplasia is the main change occurring in intestinal smooth muscle above a chronic obstruction and explains the functional obstruction seen in the proximal bowel of a jejunoileal atresia. With an experimental model in dogs, this hyperplasia has been shown to be reversible. However, changes are extreme in atresia, and experiments in animals with induced atresia will best evaluate various kinds of treatment.

  13. Percutaneous biliary drainage and stenting

    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

  14. Esophageal heterotopic gastric mucosa in esophageal atresia

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available Heterotopic gastric mucosa (HGM is occasionally found at endoscopy in the proximal esophagus of adults and children, when it manifests as an asymptomatic small island of reddish pink mucosa just below the upper esophageal sphincter. There are few reports of esophageal HGM detected by endoscopy after repair of esophageal atresia (EA with tracheo-esophageal fistula (TEF. We report a child with multiple patches of HGM in the proximal and distal esophagus seen at endoscopy after EA/TEF repair. No obvious symptoms were related to the HGM and she remains under endoscopic surveillance. The incidence of esophageal HGM may be increased in patients with EA and its distribution can be more extensive than a simple “inlet patch”. There is evidence to suggest that esophageal HGM increases the risk of developing Barrett's esophagus and has a malignant potential. Heterotopic gastric mucosa extends the spectrum of potential pathologies affecting the esophagus in patients with EA/TEF and supports current international guidelines for endoscopic surveillance of these patients.

    Acute appendicitis is the most common acute surgical condition; making appendectomy the most commonly performed emergency surgical procedure in the world. Anomalies of the appendix are relatively uncommon. However, their presence may alter the course of pre-operative diagnosis and the surgical treatment provided, leading to medico-legal issues in certain cases as well. We hereby present the case of a 17 year-old female who had the suggestive signs, symptoms and investigations of appendicular lump. She was managed according to the Ochsner-Sherren regimen and then underwent interval open appendectomy 6 weeks later. During the procedure, the findings of a 5 cm long appendix were noted. The base of the appendix was attached to the caecum, however there was complete mucosal discontinuity between the base and the remaining portion of the appendix. A fibrous strand connected the two blind ending parts together. After thorough literature search, the authors concluded that this is only the fourth reported case of appendicular atresia ever to have been reported. Considering the rarity of this finding we feel this could be of valuable interest to surgeons and readers alike PMID:26090015

    The interventionism non-surgical biliary begins with the description of the drainage biliary percutaneous that has presented in the last 20 years a special development with the improvement of the techniques and materials for percutaneous and endoscopic use. At the present time the echographic technique allows a quick diagnosis of the possible causes of the obstructive jaundice and in most of the cases to approach the level of the obstruction; however, for a complete morphologic definition of the biliary tree; the cholangiography retrogrades endoscopic is used like first line of diagnosis and therapeutic leaving the transhepatic percutaneous cholangiography for some patients with bankrupt endoscopy or previous surgery with alteration of the anatomy and impossibility for the endoscopic canulation. Additionally, with the continuous improvement of the resonance images in the biliary duct and the new techniques of multiplanar reconstruction of the TAC have taken to that these techniques are of first diagnostic line and that the percutaneous boarding, is carried out with therapeutic and non diagnostic intention

    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

    Congenital lung malformations are increasingly detected before birth. However, bronchial atresia is rarely identified in utero and not always recognized in neonates. There are two types of atresia: (1) proximal, located at the level of the mainstem or the proximal lobar bronchi, which is extremely rare and usually lethal during pregnancy, causing a tremendous volume increase of the distal involved lung with secondary hypoplasia of the normal lung, and (2) peripheral, located at the segmental/subsegmental bronchial level, which may present as an isolated lesion or as part of a complex congenital malformation. Prenatal findings are mostly nonspecific. Postnatal exams show overinflated lung areas and focal bronchial dilations. The typical fluid-filled bronchoceles are not always observed in neonates but develop progressively in the first months of life. This pictorial essay describes the spectrum of imaging findings of bronchial atresia in fetuses, neonates and infants. (orig.)

  19. Mammalian follicular development and atresia: role of apoptosis.

    Science.gov (United States)

    Asselin, E; Xiao, C W; Wang, Y F; Tsang, B K

    2000-01-01

    The regulation of follicular development and atresia is a complex process and involves interactions between endocrine factors (gonadotropins) and intraovarian regulators (sex steroids, growth factors and cytokines) in the control of follicular cell fate (i.e. proliferation, differentiation and programmed cell death). Granulosa and theca cells are key players in this fascinating process. As atresia is the fate of most follicles, understanding of how these physiological regulators participate in determining the destiny of the follicle (to degenerate or to ovulate) at cellular and subcellular levels is fundamental. This short review summarizes the role of intraovarian modulators of programmed cell death in the induction of atresia during follicular development. Copyright 2000 S. Karger AG, Basel

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

    Directory of Open Access Journals (Sweden)

    Fuqiang Ye

    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.

    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.

    Full Text Available Apple-peel atresia or Type 3 jejuno-ileal atresia (JIA is an uncommon cause of foetal intestinal obstruction. Bowel obstruction in the foetus is diagnosed on the prenatal ultrasonography only in 50% cases. We report a case in which foetal intestinal obstruction was diagnosed on prenatal ultrasonography. The child showed signs of intestinal obstruction on day one after birth, for which an exploratory laparotomy was performed. Type 3 JIA was found for which resection of atretic segments with jejuno-ascending colon anastomosis was preformed.

  3. The "boomerang" malleus-incus complex in congenital aural atresia.

    2014-01-01

    "Boomerang" malleus-incus fusion deformity is identified on axial high-resolution CT in a subset of patients with congenital aural atresia, and it is associated with an absent incudostapedial joint and stapes capitulum and attachment of the incus to the tympanic segment of the facial nerve canal. Twelve patients with this deformity were identified on a retrospective review of imaging from a cohort of 673 patients with congenital aural atresia, with surgical confirmation in 9 of these patients. Eight of 9 patients underwent partial ossicular replacement prosthesis reconstruction with improvement in hearing outcome. We hypothesize that the boomerang anomaly represents a more severe ossicular anomaly than is normally seen in congenital aural atresia, arising from an arrest earlier in the embryonic development of the first and second branchial arch. This has potentially important implications for surgical planning because hearing outcomes with placement of prosthesis may not be as good as with conventional atresia surgery, in which reconstruction is performed with the patient's native ossicular chain. © 2014 by American Journal of Neuroradiology.

    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.

    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.

    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.

    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.)

    The occurrence of oval window atresia is a rare anomaly with conductive hearing loss. Traditional atresia surgeries involve challenging surgical techniques with risks of irreversible inner ear damage. Recent reports on Bonebridge (Medel, Innsbruck, Austria), a novel implantable bone conduction hearing aid system, assert that the device is safe and effective for conductive hearing loss. We present a case of Bonebridge implantation in an eight-year-old girl with bilateral oval window atresia.

    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

    In the liver and biliary system ultrasound has emerged as one of the most useful imaging techniques. It is usually the first radiological procedure selected and is often sufficient alone to enable a clinical decision to be made. Good result with ultrasound depend critically on expert scanning technique coupled with an understanding of tomographic anatomy and, of course, an appreciation of the clinical significance of any findings. In addition to we'd like to stress on the ultrasonical anatomy and for the technologist and also discuss about pathological part

    Full Text Available Congenital duodenal atresia complicated by gastric perforation (GP is a very rare and a very mortal condition. Only three newborns could be cured in the reported 13 cases. We report a successfully treated newborn with this complicated disease. A 2-day-old male was hospitalized with prediagnosis of duodenal obstruction. Twelve hours later, significant abdominal distention occurred promptly. At laparotomy, GP and preampullary duodenal atresia were detected. Gastrorrhaphy and duodenoduodenostomy were performed in the same operation. The patient was discharged on the 15th postoperative day. This complicated disease can be treated by early diagnosis and surgical intervention. We choose one-stage operation because of the clean peritoneal cavity. However, generalized peritonitis may require two-stage operation in delayed cases.

    Congenital pyloric atresia (CPA) is a very rare malformation that constitutes less than 1% of all gas upper gastrointestinal atresias. It is a unique malformation that is commonly seen as an isolated lesion, but can also occur in association with other genetically determined conditions such as hereditary multiple intestinal atresias (HMIA). This is a report of two cases of isolated isolated CPA, outlining aspects of diagnosis and management. A 2-day-old female, a product of 35-weeks gestation via a low cesarean delivery due to a transverse lie to a 25-year-old mother who had gestational insulin dependent diabetes and polyhydraminos was referred because of non-bile stained vomiting. Her abdominal x-ray showed dilated stomach with no gas distally. Gastrograffin meal confirmed the diagnosis of gastric outlet obstruction. She was found to have pyloric artesia. This was excised via longitudinal incision in the pylorus, which was then closed transversely. Subsequently she did well. A 1-year -old female was evaluated because of persistent non-bile stained vomiting. Abdominal x-ray showed dilated stomach with no gas distally and barium meal confirmed the diagnosis of gastric outlet obstruction. She was operated and on during surgery was found to have congenital pyloric atresia. This was excised via longitudinal incsion in the pylorus. She did well. CPA is divided in three types: 1) Pyloric membrane 2) Pyloric artesia without a gap 3) Pyloric artesia with a gap. Both our patients have pyloric diaphagrams. The treatment of CPA is surgical and depends on the type of arteseia. For those with pyloric diaphagram or pyloric artesia without a gap the treatment is excision of diphagaram. This is also of importance in case there is more than one diaphagram. For those with pyloric artesia with a gap, if the gap is short, they should be treated with a Finny or Heineke-Mickulicz pyloroplasty, but if the gap is long then a gastroduodenostomy becomes the treatment of choice

    We studied the angiographic findings in 65 patients with congenital pulmonary atresia, ages 4 days to 14 years (mean 3.3 yrs), from 1981 to 1986 at Severance Hospital Yonsei University. 1. 6 had pulmonary atresia with an intact interventricular septum, 38 had it with cardiac anomaly Renodynamically simulating TOF, and 21 associated with more complicated cardiac anomalies. 2. In the group with an intact ventricular septum, 5 showed confluent intrapericardial pulmonary artery, all segmental pulmonary arteries connected to intrapericardial artery. 3. In the group simulating TOF, aorta arose from RV with or without overriding in 35. In 27 patients with confluent intrapericardial pulmonary artery, 23 had more than 10 segmental pulmonary arteries connected to intrapericardial artery and 5 had severely hypoplastic hilar pulmonary arteries. In 11 with non confluent intrapericardial pulmonary artery, 4 had more than 10 segmental pulmonary arteries connected to central pulmonary artery and 9 had severely hypoplastic hilar pulmonary arteries. 4. In the group associated with more complicated cardiac anomaly, included 8 patients with atrioventricular discordance, 7 with univentricular heart and 6 with tricuspid atresia. In 17 patients with confluent intrapericardial artery, 16 had more than 10 segmental pulmonary arteries connected to intrapericardial artery, one showed severe hypoplasia of hilar pulmonary arteries. In another 4 with non confluence, no one showed more than 10 segmental arteries connected to intrapericardial or hilar pulmonary artery.

    Full Text Available Introduction Choanal atresia (CA is a challenging surgical problem defined as a failure in the development of communication between the nasal cavity and nasopharynx. Objective The objective of this study is to describe computed tomography (CT findings in cases with bilateral choanal atresia. Methods The study involved performing axial and coronal non-contrast CT scanning with 2–3 mm sections on14 neonates that had bilateral CA. We used fiberoptic nasal endoscopy to confirm the diagnosis. We evaluated coronal CT to study the skull base area in such neonates. Results This study included 14 neonates with bilateral CA; with mean age of 7 ± 3.5 days. Mixed atretic plates were found in 12 (85.7% cases while two (14.3% had pure bony atresia. Isolated CA was detected in 9 cases (64.3% and 5 (35.7% cases had associated anomalies. Coronal CT showed soft tissue density in the nasal cavity that appeared to extend through an apparent defect in the nasal roof (cribriform plate, falsely diagnosed by radiologists as associated encephalocele. At the time of surgical repair, all patients showed thick tenacious mucous secretions in both nasal cavities and revealed no encephalocele. Nasal roof remained intact in all cases. Conclusion The thick secretion of bilateral CA could give a false encephalocele appearance on the CT. It is highly recommended to perform proper suction of the nasal cavity of suspected CA cases just before CT scanning.

    2015-08-01

    Dysphagia or swallowing disorder is very common (range, 15-52%) in patients with esophageal atresia. Children present with a wide range of symptoms. The most common diagnostic tools to evaluate esophageal dysphagia, such as upper barium study and manometry, aim to characterize anatomy and function of the esophageal body and the esophagogastric junction (EGJ). Using these technologies, a variety of pathological motor patterns have been identified in children with esophageal atresia. However, the most challenging part of diagnosing patients with esophageal dysphagia lies in the fact that these methods fail to link functional symptoms such as dysphagia with the esophageal motor disorders observed. A recent method, called pressure-flow analysis (PFA), uses simultaneously acquired impedance and manometry measurements, and applies an integrated analysis of these recordings to derive quantitative pressure-flow metrics. These pressure-flow metrics allow detection of the interplay between bolus flow, motor patterns, and symptomatology by combining data on bolus transit and bolus flow resistance. Based on a dichotomous categorization, flow resistance at the EGJ and ineffective esophageal bolus transit can be determined. This method has the potential to guide therapeutic decisions for esophageal dysmotility in pediatric patients with esophageal atresia. Georg Thieme Verlag KG Stuttgart · New York.

    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 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.

    Full Text Available BACKGROUND/PURPOSE: The purpose of this prospective study was to review the operative findings, treatment strategies, as well as the results of management of 46 consecutive cases of jejunoileal and colonic atresia, managed over a 2-year period. MATERIALS AND METHODS: There were 42 patients with jejunoileal atresia (JIA and 4 with colonic atresia (CA. The 4 group types were: type I-membranous (n=20, type II- blind ends separated by a fibrous cord (n=6, type IIIa- blind ends with a V-shaped mesenteric defect (n=10, type IIIb- apple-peel atresia (n=4 and type IV- multiple atresias (n=6. Primary surgery for JIA consisted of resection with a single anastomosis (n=37, anastomosis after tapering jejunoplasty (n=3, multiple anastomosis (n=1 and a Bishop-Koop ileostomy (n=1. For CA, resection with primary anastomosis was performed. A single end-to-oblique anastomosis after adequate resection of dilated proximal bowel, was the preferred surgical procedure. In the absence of facilities for administering TPN, early oral/nasogastric (NG tube feeding was encouraged. In patients with anastomotic dysfunction, conservative treatment of the obstruction followed after its resolution by gradually increased NG feeds, was the preferred treatment protocol. RESULTS: Late presentation or diagnosis with hypovolemia, electrolyte imbalance, unconjugated hyperbilirubinemia (n=25 and sepsis (n=6, were significant preoperative findings. After resection and anastomosis, significant shortening of bowel length was seen in 16 patients (34.7%. Postoperative complications included an anastomotic leak (n=3, a perforation proximal to the anastomosis in 1 and anastomotic dysfunction in 5 patients. Full oral or NG tube feeding was possible only by the 13th to 31st postoperative day (POD, after the primary surgery in patients with anastomotic dysfunction and those undergoing reoperation. Overall, 38 patients survived (82.6%. Mortality was highest in patients with type IIIb or type IV

    Full Text Available Anastomotic stricture (AS and recurrent tracheoesophageal fistula (TEF are two complications of surgical repair of esophageal atresia (EA. Therapeutic endoscopic modalities include stenting, tissue glue, and clipping for TEF and endoscopic balloon dilation bougienage and stenting for esophageal strictures. We report herein a two-month infant with both EA and TEF who benefited from a surgical repair for EA, at the third day of life. Two months later he experienced deglutition disorders and recurrent chest infections. The esophagogram showed an AS and a TEF confirmed with blue methylene test at bronchoscopy. A partially covered self-expanding metal type biliary was endoscopically placed. Ten weeks later the stent was removed. This allows for easy passage of the endoscope in the gastric cavity but a persistent recurrent fistula was noted. Instillation of contrast demonstrated a fully dilated stricture but with a persistent TEF. Then we proceeded to placement of several endoclips at the fistula site. The esophagogram confirmed the TEF was obliterated. At 12 months of follow-up, he was asymptomatic. Stenting was effective to alleviate the stricture but failed to treat the TEF. At our knowledge this is the second case of successful use of endoclips placement to obliterate recurrent TEF after surgical repair of EA in children.

    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.

    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.

    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.

    Full Text Available Objective. To illustrate the role of multislice computed tomography and local contrast instillation in the diagnosis and characterization of choanal atresia. To review the common associated radiological findings. Methods. We analyzed 9 pediatric patients (5 males and 4 females with suspected choanal atresia by multislice computed tomography. We recorded the type of atresia plate and other congenital malformations of the skull. Results. Multislice computed tomography with local contrast installed delineated the posterior choanae. Three patients had unilateral mixed membranous and bony atresia. Three patients had unilateral pure bony atresia. Only 1 of 7 patients have bilateral bony atresia. It also showed other congenital anomalies in the head region. One patient is with an ear abnormality. One patient had congenital nasal pyriform aperture stenosis. One of these patients had several congenital abnormalities, including cardiac and renal deformities and a hypoplastic lateral semicircular canal. Of the 6 patients diagnosed to have choanal atresia, 1 patient had esophageal atresia and a tracheoesophageal fistula. The remaining patients had no other CHARGE syndrome lesions. Conclusions. Local Contrast medium with the application of the low-dose technique helps to delineate the cause of the nasal obstruction avoiding a high radiation dose to the child.

    There is an extensive menu for investigating the hepatobiliary area. From the simplicity of the plain film to the expense of magnetic resonance imaging to the invasiveness of percutaneous transhepatic cholangiography, all modalities can contribute to the goal of a correct diagnosis. Not all are needed in each patient; thus a careful evaluation of the clinical needs is required before proceeding. It is also apparent that changes are occurring rapidly. The current importance of gallbladder ultrasonography and computerized tomography and the decline of oral cholecystography and intravenous cholangiography in biliary tract diagnosis was impossible to anticipate a decade ago. Because not all modalities are available in all communities, it is important to tailor the diagnostic algorithm to local skills and equipment

    To demonstrate a comprehensive review of published articles regarding endoscopic ultrasound (EUS)-guided biliary drainage. Review of studies regarding EUS-guided biliary drainage including case reports, case series and previous reviews. 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.

  2. [Association of biliary calculosis and portal cavernomatosis].

    1992-08-01

    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.

Three newborns with bilateral pulmonary vein atresia were encountered at our institution during a period of 8 years. We evaluated prenatal echocardiographic findings, clinical presentations, postnatal echocardiographic findings, chest radiographic findings, cardiac CT findings and clinical outcomes. All newborns presented immediately after birth with severe cyanosis, respiratory distress and acidosis that were unresponsive to medical management. Prenatal and postnatal echocardiographic studies and chest radiography were misleading, inconclusive or nonspecific in making the diagnosis in these children; however cardiac CT clearly demonstrated atresia of the bilateral pulmonary veins with multiple small mediastinal collateral veins and pulmonary edema. Surgical treatments were not feasible for this anomaly. Their clinical outcomes were universally dismal and all infants died within 3 days. Cardiac CT provides an accurate diagnosis of bilateral pulmonary vein atresia and leads to prompt treatment decision in these children. (orig.)

  5. Endoscopic management of biliary injuries and leaks

    2012-01-01

    Full Text Available Bile duct injuries and subsequent leaks can occur following laparoscopic and open cholecystectomies and also during other hepatobiliary surgeries. 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.

    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 Background: Definitive treatment of isolated esophageal atresia (IEA is still controversial. A study was conducted to review cases of IEA in our department with a view to evaluate the long term results of definitive surgery in these patients. Materials and Methods: Nine consecutive patients with IEA were included in the study. All babies initially underwent cervical esophagostomy and feeding gastrostomy. One baby also had anorectal atresia and needed a colostomy. In 6 babies, end esophagostomy was performed while in 3 babies, lateral esophagostomy was performed. Of the 6 babies with end esophagostomy, two underwent jejunal Interpositioning, two had serial extra-thoracic lengthening and two reverse gastric tube interpositiong. Three babies with lateral esophagostomy were planned for delayed primary repair. Results: Both babies with jejunal interpositiong initially did well; serious gastro-esophageal reflux occurred in one baby who needed antireflux surgery. At 6 years follow-up both children had redundant Jejunum. Recurrent Respiratory tract infection remained a problem in one child while other is doing well. Of the two babies with extrathoracic lengthening it was possible to perform end to end anastomosis in one baby but in the other extrathoracic lengthening did not work and gastric transpositioning was performed. Of the two babies with reverse gastric tube interpositioning one developed esophageal stenosis at the site of anastomosis and is on serial dilatations. Other died due to anastomotic leak and mediastinitis. In all the three babies with lateral esophagostomy spontaneous lengthening of esophagus was noted. End to end anastomosis was possible in two of these babies who are doing well. One is waiting definitive surgery. Number of complications, hospital stay and cost of surgery was least in patients with lateral esophagostomy. Conclusion: Various methods of definitive treatment have been proposed for isolated esophageal atresia but each

    An unusual anatomic configuration of segmental tracheal agenesis/atresia with esophageal duplication on autopsy in a fetus that demised in utero at 29 weeks is reported. The mother was scanned initially for a cardiac anomaly at 20 weeks and on follow-up scan at 27 weeks had polyhydramnios and underwent amnioreduction. The final autopsy diagnosis was vertebral, ano-rectal, cardiac, tracheoesophageal, renal, and limb malformations (VACTERL). We discuss the autopsy findings along with the embryological mechanisms and compare the configuration with Floyd's classification for tracheal agenesis. The difficulties in prenatal diagnosis are discussed.

    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 a normal wind year, Danish wind turbines generate the equivalent of approx. 20 percent of the Danish electricity demand. This paper argues that only approx. 1 percent of the wind power production is exported. The rest is used to meet domestic Danish electricity demands. The cost of wind power...... misleading. The cost of CO2 reduction by use of wind power in the period 2004-2008 was only 20 EUR/ton. Furthermore, the Danish wind turbines are not paid for by energy taxes. Danish wind turbines are given a subsidy via the electricity price which is paid by the electricity consumers. In the recent years...... is paid solely by the electricity consumers and the net influence on consumer prices was as low as 1-3 percent on average in the period 2004-2008.

    The binomial PTBD-cholangitis often stands under different and sometimes even opposite relations. Among its indications the procedure lists, the treatment of cholangitis which, on the other hand, may be itself a complication of biliary drainage. The present work proposes a critical review of cholangitis-PTBD correlations, from an ordinary clinical-radiological point of view. Different pathogenetic hypothesis of cholangitis (inflammation, cholestasis, surgical manipulation) are discussed together with risk factors (impaired macrophagic-phagocytic system, immunosuppresion, wide neoplastic liver involvement, multiple intrahepatic ductal obstructions, chronic liver diseases, aged patients, etc.). The authors also report about prevention and treatment of septic complications which must be carried out following technical and therapeutic strategies, such as chemoprophylaxis and focused antibiotic therapy according to coltural samples, slow injection of small amounts of contrast medium, peripheral branches approach, gentle handling of catheters and guidewires, flushing with saline solutions and brushing of the catheter itself, and finally use of large gauge catheters in the presence of bile sludge

    The aim was to evaluate surgical techniques and their relationship to postoperative success rate and hearing outcomes in acquired atresia of the external auditory canal. In this article, 24 patients with acquired atresia of the external auditory canal were retrospectively evaluated regarding their canal status, hearing, and postoperative success. Acquired stenosis occurs more commonly in males with a male: female ratio of 2-3:1; it seems to be a disorder affecting young adults. Previous ear surgery (13 patients, 54.2%) and external ear trauma (11 patients, 45.8%) were the main etiological factors of acquired ear canal stenosis. Mastoidectomy (12/13) and traffic accidents (8/11) comprise the majority of these etiological factors. Endaural incision is performed in 79.2% and postauricular incision for 20.8% of cases during the operation. As types of surgical approach, transcanal (70.8%), transmastoid (20.8%), and combined (8.4%) approaches are chosen. The atretic plate is generally located at the bony-cartilaginous junction (37.5%) and in the cartilaginous canal (33.3%); the bony canal is involved in a few cases only. Preserved healthy canal skin, split- or full-thickness skin grafts, or pre- or postauricular skin flaps are used to line the ear canal, but preserved healthy canal skin is preferred. The results of surgery are generally satisfactory, and complications are few if surgical principles are followed.

  6. Congenital aplasia of the optic chiasm and esophageal atresia: a case report

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available Abstract Introduction The complete absence of the chiasm (chiasmal aplasia is a rare clinical condition. Hypoplasia of the optic nerve and congenital nystagmus are almost invariably associated characteristics. Microphthalmos or anophthalmos are common features in chiasmal aplasia, while central nervous system abnormalities are less frequent. Esophageal atresia can be isolated or syndromic. In syndromic cases, it is frequently associated with cardiac, limb, renal or vertebral malformations and anal atresia. More rarely, esophageal atresia can be part of anophthalmia-esophageal-genital syndrome, which comprises anophthalmia or microphthalmia, genital abnormalities, vertebral defects and cerebral malformations. Here, a previously unreported case of chiasmal aplasia presenting without microphthalmos and associated with esophageal atresia is described. Case presentation Aplasia of the optic chiasm was identified in a Caucasian Italian 8-month-old boy with esophageal atresia. An ultrasound examination carried out at 21 weeks' gestation revealed polyhydramnios. Intrauterine growth retardation, esophageal atresia and a small atrial-septal defect were subsequently detected at 28 weeks' gestation. Repair of the esophageal atresia was carried out shortly after birth. A jejunostomy was carried out at four months to facilitate enteral feeding. The child was subsequently noted to be visually inattentive and to be neurodevelopmentally delayed. Magnetic resonance imaging revealed chiasmal aplasia. No other midline brain defects were found. His karyotype was normal. Conclusion If achiasmia is a spectrum, our patient seems to depict the most severe form, since he appears to have an extremely severe visual impairment. This is in contrast to most of the cases described in the literature, where patients maintain good--or at least useful-- visual function. To the best of our knowledge, the association of optic nerve hypoplasia, complete chiasmal aplasia, esophageal

    In our previous work, we identified a natural toxin, biliatresone, from Dysphania glomulifera and D. littoralis, endemic plants associated with outbreaks of biliary atresia in Australian neonatal livestock. Biliatresone is a very rare isoflavonoid with an α-methylene ketone between two phenyls, 1,2-diaryl-2-propenone, along with methylenedioxy, dimethoxyl, and hydroxyl functional groups, that causes extrahepatic biliary toxicity in zebrafish. The toxic core of biliatresone is a methylene in the α-position relative to the ketone of 1,2-diaryl-2-propenone that serves as an electrophilic Michael acceptor. The α-methylene of biliatresone spontaneously conjugated with water and methanol (MeOH), respectively, via Michael addition in a reverse phase high-performance liquid chromatography (RP-HPLC) analysis. We here report the reactivity of biliatresone toward glutathione (GSH), several amino acids, and other thiol- or imidazole-containing biomolecules. LC-MS and HPLC analysis of the conjugation reaction showed the reactivity of biliatresone to be in the order histidine > N-acetyl-d-cysteine (D-NAC) = N-acetyl-l-cysteine (L-NAC) > histamine > glutathione ≥ cysteine ≫ glycine > glutamate > phenylalanine, while serine and adenine had no reactivity due to intramolecular hydrogen bonding in the protic solvents. The reactivity of ethyl vinyl ketone (EVK, 1-penten-3-one), an example of a highly reactive α,ß-unsaturated ketone, toward GSH gave a 6.7-fold lower reaction rate constant than that of biliatresone. The reaction rate constant of synthetic 1,2-diaryl-2-propen-1-one (DP), a core structure of the toxic molecule, was 10-fold and 1.5-fold weaker in potency compared to the reaction rate constants of biliatresone and EVK, respectively. These results demostrated that the methylenedioxy, dimethoxyl, and hydroxyl functional groups of biliatresone contribute to the stronger reactivity of the Michael acceptor α-methylene ketone toward nucleophiles compared to that of DP

    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.

    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

  13. Biliary parasites: diagnostic and therapeutic strategies.

    Science.gov (United States)

    Khandelwal, Niraj; Shaw, Joanna; Jain, Mamta K

    2008-04-01

    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.

    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.

    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.

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.)

In import penetration tests, we find that its pricing and quantity decisions are independent of import price and quantity, implying that it can act to a considerable extent independently of its competitors. We also test whether it can act independently of its customers and find that its demand is inelastic with respect to its price. It thus holds a dominant posi...

    Full Text Available Duodenal obstruction due to duodenal atresia occurs in 1 in 10,000 live births and is the most common type of intestinal obstruction in neonates [1–3]. Gastric outlet obstruction in the newborn period from causes other than hypertrophic pyloric stenosis is very uncommon [3]. Potential etiologies include gastric volvulus, antral web, and duplication cysts. Gastric diverticula in the infant is even more rare, with only a few case reports published, and only one describes a gastric diverticulum in the presence of a duodenal atresia [4–8]. In this report, we describe the first case of a gastric outlet obstruction due to a gastric diverticulum in the presence of duodenal atresia.

    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).

    Full Text Available The distribution of healthy and atretic follicles on the ovarian surface of improved Valachian ewes 17, 24, and 32 days postpartum is reported in this study. The number of healthy follicles was higher on day 24 postpartum and their mean diameter tended to increase to day 32 (P<0.05 with the greatest diameter of 5 mm. 78–81% of atretic follicles ≥3 mm in diameter was observed where apoptosis began in the follicular cells situated at the follicular cavity. The early atretic follicles are characterized by the presence of mitotic pictures. In one ewe 24 days postpartum, small regressive follicular cysts were observed. Contracting atresia is characterized by thickening of the theca interna even to 190 μm. Progesterone and oestradiol-17β concentrations were maintained at relatively low levels, but with no significant difference between the days postpartum.

    Full Text Available Esophageal atresia (EA with tracheoesophageal fistula occurs in about 1:2,500 births. We report a case of persistent bronchography in a newborn with EA and distal tracheoesophageal fistula. A large amount of barium sulfate was injected for mistake by a tube directly in the right bronchus to evaluate the patency of the esophagus. The infant showed signs of respiratory distress; he was intubated and transported at children's Hospital Santobono Pausilipon. Here, it was performed a chest X-ray that confirmed the opacification of the right bronchial tree, and it was suspected an EA type 3b. The literature recommends that: evaluation of the patency of the esophagus, with an iodinate contrast medium, should be done in a pediatric specialized center for high risk of lung aspiration.

    2007-10-01

    The treatment of long gap esophageal atresia remains a major surgical challenge. The authors describe a modification of a lengthening technique based on tissue expansion to avoid sutures cutting through the esophagus. Between January 2004 and August 2006, 4 patients did not respond to stretching, and underwent this modified esophageal lengthening technique using silastic tubes. RESULTS AND FOLLOW-UP: All infants recovered and have an intact esophagus. All infants developed gastroesophageal reflux. Thal antireflux procedure was performed in the first infant. The other 3 patients were managed conservatively. Follow-up ranged between 6 and 34 months. The tissue expansion principle can be successfully applied in the esophagus through external traction. Silastic tube fixation at esophageal ends may help to apply even traction and avoid sutures cutting through the esophageal tissue.

  14. Dysmotility in Esophageal Atresia: Pathophysiology, Characterization, and Treatment

    Science.gov (United States)

    Faure, Christophe; Righini Grunder, Franziska

    2017-01-01

    Esophageal dysmotility is almost universal after esophageal atresia (EA) repair and is mainly related to the developmental anomaly of the esophagus. Esophageal dysmotility is involved in the pathophysiology of numerous symptoms and comorbidities associated with EA such as gastroesophageal reflux disease, aspiration and respiratory complications, and symptoms of dysphagia and feeding disorders. High-resolution esophageal manometry (HREM) has facilitated the characterization of the dysmotility, but there is an incomplete correlation between symptoms and manometrical patterns. Impedance coupled to HREM should help to predict the clinical outcome and therefore personalize patient management. Nowadays, the management of esophageal dysmotility in patients with EA is essentially based on treatment of associated inflammation related to peptic or eosinophilic esophagitis. PMID:28620599

    Full Text Available A rare case of neonatal Bartter syndrome presenting with severe hyperkalemia is reported in a preterm child born to consanguineous parents. This child also had ileal atresia, and meconium plugs were found at laparotomy. The diagnosis of cystic fibrosis was subsequently made on genetic testing. Despite full intensive care management and surgical interventions, he died of respiratory failure after 70 days. This is the first reported case of such conglomeration of pathologies in a newborn child. Second, in highlighting this case we want clinicians to be aware that a subtype of neonatal Bartter syndrome can present with initial hyperkalemia so that an erroneous diagnosis of pseudohypoaldosteronism is not made when this is seen in combination with hyperkalemia and hyperrenin hyperaldosteronism.

  20. Extrahepatic biliary cystadenoma with mesenchymal stroma: a true biliary cystadenoma? A case report.

    LENUS (Irish Health Repository)

    Hennessey, Derek B

    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.

  1. Atresia of large ovarian follicles of the rat

    2011-08-01

    Full Text Available In the rat, at the beginning of pregnancy a cohort of antral follicles develops until the preovulatory stage. However, these follicles, differentiating in the hyperprolactinemic milieu, produce only small amount of estradiol, do not ovulate and undergo rapid degeneration. They constitute an interesting physiological model of atresia. In the present study, we analysed the development and subsequent degeneration of such follicles. The study was performed on Wistar female rats killed in succession between days 1-9 of pregnancy. Excised ovaries were submitted to a routine histological procedure. Paraffin sections were subjected to hematoxylin and eosin staining or in situ DNA labelling. Histological and TUNEL staining revealed that the investigated group of follicles grew slower than that on the corresponding days of the estrous cycle and reached a preovulatory size and morphological appearance on day 5 of pregnancy. They did not ovulate and between days 6 and 9 of pregnancy an increasing number of apoptotic cells appeared within these follicles. They were localized predominantly in the antral granulosa layer, especially near the cumulus oophorus complex (COC and in the region linking the COC with the follicular wall. The COC and the theca layer were much less affected. In late stages of atresia, also cumulus cells became apoptotic but degenerating oocytes did not exhibit positive TUNEL staining. Only limited number of the theca cells have undergone apoptosis and generally they were not hypertrophied. Our findings indicate that much smaller than normal amount of intrafollicular estradiol was sufficient to support a normal, according to the morphological criteria, although slower development of antral follicles to the late preovulatory stage.

    2000-01-01

    Over the years from 1992 to 1997, 41 anorectal malformations (ARM) with histopathologic alterations were investigated to determine which morphologic abnormalities of the distal rectum accompany ARMs. Three other cases showed normal neuromuscular morphology; 9 further cases could not be evaluated owing to scanty biopsies. All resected specimens were caudocranially coiled and cryostat cut at -20 degrees C into serial sections, which were stained with a lactic dehydrogenase, succinic dehydrogenase, nitroxide synthase, and acetylcholinesterase reaction as well as hemalum and sirius red. Ten low, 15 intermediate, and 10 high forms of anal atresia (AA) were studied. In addition, six cloacal abnormalities were investigated. In 7 cases (17%) (5 intermediate, 2 low AAs), the characteristics of Hirschsprung's disease were observed. Oligoneuronal hypoganglionosis of the myenteric plexus proximal to the anal floor was diagnosed in 7 AAs (12%). In 10 children with high-type AA and resection of 1-5 cm distal rectum and in all cloacal anomalies (n = 6) defects of the muscularis propria were seen in the rectal-atresia sac. These defects were characterized by hypoplasia of the circular-muscle layer and/or the internal anal sphincter (IAS). Intestinal neuronal dysplasia of the submucous plexus was most frequently observed (12%) in high-type AA. A correlation between innervation anomalies or anomalies of the muscularis propria and the type of fistula could not be seen. In conclusion, all cases with high-type AA and cloacal anomalies were characterized by anomalies of the muscularis propria and/or IAS but this was not the case in intermediate and low-type AAs. Anomalies of the enteric nervous system were diagnosed in 60% of AAs.

    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.

    The objectives of this study are to evaluate the surgical management, both definitive and palliative, in selected patients with biliary obstruction and to find out the postoperative morbidity and mortality in these patients. Duration of the study is two years conducted from June 2002 to May 2004. The study was carried out at. the surgical. unit 4 of the Combined Military Hospital and surgical department of the Military Hospital. Thirty eight cases of biliary obstruction were included. A convenient sampling technique was followed. Data analyzed by using SPSS version 10.0 for windows on computer. Descriptive statistics like frequency, percentage, average etc were computed for data presentation. Any inferential test-was not found to be applicable for this descriptive type case series. We selected 38 patients with features of extrahepatic biliary obstruction. Out of these (n 38) 15 patients (39.5%) suffered from benign diseases while those having malignant diseases were 23 (60.5%). 19 (50%) patients died within two years of follow up while 19 (50%) were the survivors. Mortality was maximum for the malignant cases. In benign cases only one patient died. Maximum deaths 6 (31.6%) occurred in the period of up to one month of operation. 20 patients had one or another complication of operation and hence the morbidity came out to be 52%. According to our results the mortality and morbidity related to extrahepatic biliary obstruction in our patients was higher compared to other studies which can only be reduced by early detection and treatment.

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

    Full Text Available Functional pulmonary atresia is characterized by a structurally normal pulmonary valve that does not open during right ventricular ejection. It is usually associated with Ebstein′s anomaly, Uhl′s anomaly, neonatal Marfan syndrome and tricuspid valve dysplasia. However, functional pulmonary atresia is rarely reported in newborn with anatomically normal heart. We report a newborn with functional pulmonary atresia who had normal intracardiac anatomy, who responded to treatment with nitric oxide and other vasodilator therapy successfully.

    Full Text Available More than 99% of ovarian follicles undergo atresia in mammals, but the mechanism of follicular atresia remains to be elucidated. In this study, we explored microRNA (miRNA regulation of follicular atresia in porcine ovary. A miRNA expression profile was constructed for healthy, early atretic, and progressively atretic follicles, and the differentially expressed miRNAs were selected and analyzed. We found that miR-26b, which was upregulated during follicular atresia, increased the number of DNA breaks and promoted granulosa cell apoptosis by targeting the ataxia telangiectasia mutated gene directly in vitro.

    Full Text Available Background: Supra-Transumbilical Laparotomy (STL has been used in paediatric surgery for a broad spectrum of abdominal procedures. We report our experience with STL approach for small bowel atresia repair in newborns and review previous published series on the topic. Patients and Methods: Fourteen patients with small bowel atresia were treated via STL approach at our Institution over a 5-year period and their charts were retrospectively reviewed. Results: STL procedure was performed at mean age of 3.1 day. No malrotation disorders were detected with pre-operative contrast enema. Eight patients (54.1% presented jejunal atresia, five (35.7% ileal atresia, and one (7.1% multiple ileal and jejunal atresias. Standard repair with primary end-to-back anastomosis was performed in all but one patient. In the newborn with multiple atresia, STL incision was converted in supra-umbilical transverse incision due to difficulty of exposition. After surgery, one patient developed anastomotic stricture, and another developed occlusion due to adhesions: Both infants required second laparotomy. No infections of the umbilical site were recorded, and cosmetic results were excellent in all patients. Conclusions: Increasing evidence suggests that STL approach for small bowel atresia is feasible, safe and provides adequate exposure for small bowel atresia surgery. When malrotation and colonic/multiple atresia are pre-operatively ruled out, STL procedure can be choosen as first approach.

    2013-09-01

    This study evaluates the effect of unilateral conductive hearing loss secondary to aural atresia on elementary school children's academic performance. Case control survey and review of audiometric data. One hundred thirty-two surveys were mailed to families of children with aural atresia, and 48 surveys were sent to families of children with unilateral sensorineural hearing loss (SNHL) to identify rates of grade retention, use of any resource, and behavioral problems. Audiometric data of the cohort were tabulated. Of the 40 atresia patients, none repeated a grade, but 65% needed some resources: 12.5% currently use a hearing aid, 32.5% use(d) a frequency-modulated system in school, 47.5% had an Individualized Education Plan, and 45% utilized speech therapy. Compared to the unilateral SNHL group and a cohort of children with unilateral SNHL in an earlier study, children with unilateral atresia were less likely to repeat a grade. Children in both unilateral atresia and SNHL groups were more likely to utilize some resource in the academic setting compared to the unilateral SNHL children in the prior study. Unilateral conductive hearing loss due to aural atresia has an impact on academic performance in children, although not as profound when compared to children with unilateral SNHL. The majority of these children with unilateral atresia utilize resources in the school setting. Parents, educators, and health care professionals should be aware of the impact of unilateral conductive hearing loss and offer appropriate habilitative services.

    Since 1998 Denmark has been in a process of re-regulating its energy market introducing competition and incentive based economic regulation. The ''Danish model'' reflects specific Danish political priorities on energy, environment and the role of the energy consumers. The paper focuses on the electricity sector, tracing the reasons why Denmark re-regulates the way it does and what are the results. Denmark is a small country of 43000 2 kilometers and 5.3 million inhabitants. Denmark is a net-exporter of oil and gas produced in the North Sea. The hydro-resources are negligible. Renewable energy, however, covers 11 percent of gross energy consumption.(author)

    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.

    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.

    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.

    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.

    Singh, Rajiv Ranjan; Singh, Virendra

    2015-01-01

    Hilar biliary strictures are caused by various benign and malignant conditions. It is difficult to differentiate benign and malignant strictures. Postcholecystectomy benign biliary strictures are frequently encountered. Endoscopic management of these strictures is challenging. An endoscopic method has been advocated that involves placement of increasing number of stents at regular intervals to resolve the stricture. Malignant hilar strictures are mostly unresectable at the time of diagnosis and only palliation is possible.Endoscopic palliation is preferred over surgery or radiological intervention. Magnetic resonance cholangiopancreaticography is quite important in the management of these strictures. Metal stents are superior to plastic stents. The opinion is divided over the issue of unilateral or bilateral stenting.Minimal contrast or no contrast technique has been advocated during endoscopic retrograde cholangiopancreatography of these patients. The role of intraluminal brachytherapy, intraductal ablation devices, photodynamic therapy, and endoscopic ultrasound still remains to be defined. PMID:26191345

    Purpose: To report on the frequency and treatment of arterial complications due to percutaneous transhepatic biliary drainage (PTBD).Materials: Lesions of the intrahepatic artery were encountered in 10 of 525 patients treated by PTBD (2%). Hemobilia followed in 9 patients and subcapsular hematoma in 1. Seven patients had a benign biliary stenosis and 3 had a malignant stenosis.Results: The bleeding resolved spontaneously in 3 patients. In 7 it required arterial embolization, which was successfully achieved either through the percutaneous catheter (n= 3) or by arteriography (n= 4).Conclusion: Arterial bleeding is a relatively rare complication of PTBD that can easily be treated by selective arterial embolization when it does not resolve spontaneously. In this series its frequency was much higher (16%) when the stenosis was benign than when it was malignant (0.6%)

    Full Text Available Background: Isolated oesophageal atresia without tracheo-oesophageal fistula represents a major challenge for most paediatric surgeons. Here, we present our experience with six neonates with isolated oesophageal atresia who successfully underwent immediate primary anastomosis using multiple Livaditis circular myotomy. Materials and Methods: All six neonates were gross type A isolated oesophageal atresia (6%, from among 102 neonates with oesophageal atresia, treated between January 2009 and December 2013. Five neonates were female; one was male. The mean birth weight was 2300 (range 1700-3100 g. Results: All six neonates successfully underwent immediate primary anastomosis using multiple myotomies (mean 3; range 2-4 within 10 (median 3 days after birth. The gap under traction ranged from 6 to 7 cm. One neonate died of a major cardiac anomaly. Another neonate was lost to follow-up after being well for 3 months. Three anastomotic strictures were treated with balloon dilatation, and four anastomotic leaks were treated conservatively. The mean duration of follow-up was 33 months. Conclusions: To treat isolated oesophageal atresia, an immediate primary anastomosis can be achieved using multiple myotomies. Although, this approach is associated with high complication rates, as are other similar approaches, these complications can be overcome.

    Many parents and children utilize the Internet for health-related information, but the quality of these websites can vary. The objective of this study was to assess the quality and readability of microtia and aural atresia related websites. The search engine Google was queried with the terms 'microtia' and 'aural atresia.' The first 30 results were evaluated, and those websites containing original information written in English were reviewed. Quality of content was assessed with the DISCERN instrument, and readability was assessed with the Flesch-Kincaid Reading Grade Level (FKGL) and the Flesch Reading Ease Score (FRES) tests. Each website was also reviewed for ownership and the date of last update. Sixteen microtia and 14 aural atresia websites were included for full review. The mean DISCERN score for microtia websites was 54.4 (SD=8.3), and for aural atresia websites it was 47.6 (SD=10.7), which indicates 'good' and 'fair' quality of content, respectively. Readability assessments showed an average reading level requiring a grade 10 education on FKGL, and only one microtia (6.3%) and one aural atresia (7.1%) websites were deemed to be at 'reasonable' reading level on FRES. High-quality websites that are considered easily comprehensible to the general public were lacking. Since parents and children may use websites when making treatment decisions, physicians should be aware of the quality of health information pertaining to their area of expertise available on the Internet.

  5. Association of Nasal Nostril Stenosis with Bilateral Choanal Atresia: A Case Report

    Directory of Open Access Journals (Sweden)

    Shahin Abdollahifakhim

    2014-01-01

    Full Text Available Introduction: Neonatal nasal airway obstruction induces various degrees of respiratory distress. The management of this disease, including surgical repair, will depend on the severity and location of the obstruction. We describe here a case of congenital nasal nostril stenosis that required surgical repair for stenting of both nares after coanal atresia repair.   Case Report: A 2 days old female newborn referred to neonatal department of Tabriz Children’s Hospital affiliated to the University of Medical Sciences of Tabriz, Iran on the 3rd of December, 2011 immediately after birth with respiratory distress due to bilateral coanal atresia and nasal hypoplasia with very small nostrils. CT scan showed normal brain and bilateral choanal atresia with normal size Pyriform apertures.   Conclusion: Nasal obstruction can lead to airway compromise and respiratory distress. Congenital bony nasal deformities are being recognized as an important cause of newborn airway obstruction. Nasal hypoplasia is seen in many craniofacial syndromes. Although our patient had hypoplastic nostrils with respiratory distress due to bilateral coanal atresia, correction of hypoplastic nostrils was necessary for completing the operation of choanal atresia.

    To report the usual postoperative course and complications after pull-through vaginoplasty for isolated distal vaginal atresia. Retrospective chart review at Texas Children's Hospital of all patients who were diagnosed with isolated distal vaginal atresia and underwent pull-through vaginoplasty during the study time frame. None. Postoperative complications such as vaginal stenosis or infection and postoperative vaginal diameter. Sixteen patients were identified and charts were reviewed. Patients were initially evaluated by pelvic magnetic resonance imaging and found to have distended hematometrocolpos with distal vaginal atresia. All patients underwent pull-through vaginoplasty with similar operative techniques. The average distance from the perineum to the level of the obstruction was 1.84 ± 1.2 cm. Two patients, both with obstructions at greater than 3 cm, experienced stricture formation postoperatively. Four patients (25%) experienced postoperative vaginitis. One patient (6.25%) experienced a postoperative urinary tract infection. Two groups (3 cm or less versus greater than 3 cm) were compared, and the presence of stricture was statistically different based on mean centimeters from perineum prior to pull-through vaginoplasty (P = .038). Distal vaginal atresia is managed with pull-through vaginoplasty. Atresias that extend greater than 3 cm from the perineum are at increased risk for vaginal stricture formation and should be followed to monitor for their formation. Other complications are infrequent and minor. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology. Published by Elsevier Inc. All rights reserved.

    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)

    Findings of hepatic and gallbladder ultrasonography were analyzed in 12 dogs with gallbladder and/or extrahepatic biliary tract obstruction and compared with the results of exploratory laparotomy. Hepatic ultrasonography demonstrated normal liver in 2 dogs and hepatic abnormalities in 10 animals. The following ultrasonographic diagnoses were established compared to surgical findings: gallbladder obstruction caused by bile sludge (correct/incorrect: 1/2, surgical diagnosis: choleliths in one case), gallbladder obstruction caused by neoplasm (0/1, surgical diagnosis: mucocele), gallbladder and extrahepatic biliary tract obstruction due to choleliths (3/3), extrahepatic biliary tract obstruction caused by pancreatic mass (1/1) and small intestinal volvulus (1/1). Bile peritonitis caused by gallbladder rupture (4/4) was correctly diagnosed by ultrasound, aided with ultrasonographically-guided abdominocentesis and peritoneal fluid analysis. Rupture of the gallbladder should be suspected in the presence of a small, echogenic gallbladder or in the absence of the organ together with free abdominal fluid during ultrasonography. Laparotomy was correctly indicated by ultrasonography in all cases. However, the direct cause of obstruction could not be determined in 2 of the 12 dogs by ultrasonography alone.

  9. Malignant Biliary Obstruction: Evidence for Best Practice

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

    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.

    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

    2017-01-01

    Full Text Available Oesophageal atresia is a common malformation in which the survival rate in developed countries is around 90%, while its mortality remains very high in developing countries. Oesophageal stricture post-oesophageal atresia repair is traditionally treated by non-surgical approach. However, surgical resection of the oesophageal stricture may be necessary after the failure of dilations. We report one case of refractory oesophageal stricture post-EA repair in a 3-year-old girl, who underwent oesophageal atresia Type III repair at 11-day-old. We performed an end-to-end oesophageal anastomosis with tracheal oesophageal fistula closure by extra-pleural approach. The patient was lost to follow-up for 3 years. She was seen later for anastomotic oesophageal stricture with the failure of oesophageal dilatations. Surgical resection of oesophageal stricture was performed with end-to-end oesophageal anastomosis.

    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.

    To determine the computed tomographic (CT) findings of atresia and stenosis of the external auditory canal (EAC), and to describe associated abnormalities in surrounding structures. We retrospectively reviewed the axial and coronal CT images of the temporal bone in 15 patients (M:F=8:7;mean age, 15.8 years) with 16 cases of EAC atresia (unilateral n=11, bilateral n=1) and EAC stenosis (unilateral n=3). Associated abnormalities of the EAC, tympanic cavity, ossicles, mastoid air cells, eustachian tube, facial nerve course, mandibular condyle and condylar fossa, sigmoid sinus and jugular bulb, and the base of the middle cranial fossa were evaluated. Thirteen cases of bony EAC atresia (one bilateral), with an atretic bony plate, were noted, and one case of unilateral membranous atresia, in which a soft tissue the EAC. A unilateral lesion occurred more frequently on the right temporal bone (n=8, 73%). Associated abnormalities included a small tympanic cavity (n=8, 62%), decreased mastoid pneumatization (n=8, 62%), displacement of the mandibular condyle and the posterior wall of the condylar fossa (n=7, 54%), dilatation of the Eustachian tube (n=7, 54%), and inferior displacement of the temporal fossa base (n=8, 62%). Abnormalities of ossicles were noted in the malleolus (n=12, 92%), incus (n=10, 77%) and stapes (n=6, 46%). The course of the facial nerve was abnormal in four cases, and abnormality of the auditory canal was noted in one. Among three cases of EAC stenosis, ossicular aplasia was observed in one, and in another the location of the mandibular condyle and condylar fossa was abnormal. In the remaining case there was no associated abnormality. Atresia of the EAC is frequently accompanied by abnormalities of the middle ear cavity, ossicles, and adjacent structures other than the inner ear. For patients with atresia and stenosis of this canal, CT of the temporal bone is essentially helpful in evaluating these associated abnormalities.

    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.

    First branchial cleft abnormalities are rare. They may involve the external auditory canal and middle ear. We describe a 6-year-old girl with congenital external auditory canal atresia, microtia, and cholesteatoma of mastoid and middle ear in addition to the first branchial cleft abnormalities. Clinical features of the patient are briefly described and the embryological relationship between first branchial cleft anomaly and external auditory canal atresia is discussed. The surgical management of these lesions may be performed, both the complete excision of the sinus and reconstructive otologic surgery.

    Full Text Available The management of oesophageal atresia and tracheo-oesophageal atresia (OATOF is very challenging. While in developed countries survival of patients with this condition has improved, the outcome in many developing countries has been poor. Primary repair through a thoracotomy (or video-assisted thoracoscopic surgery where available is the gold standard treatment of OATOF. However, in our setting where patients typically present late and with minimum support resources such as Neonatal Intensive Care Unit and total parenteral nutrition; staged repair may be the only hope of survival of these patients and this communication highlights the essential steps of this mode of treatment.

    Danish Hip Arthroscopy Registry (DHAR) was initiated in 2012 as a web-based prospective registry. The purpose of this study was to evaluate and report the epidemiologic and perioperative data of the first 2000 procedures in a Danish hip arthroscopy population and to describe the development of DHAR...... was 0.65 and HAGOS sub-scores were 51 (pain), 49 (symptoms), 53 (ADL), 35 (sport), 20 (physical activity) and 29, respectively. We conclude that patients undergoing hip arthroscopy report considerable pain, loss of function, reduced level of activity and reduced quality-of-life prior to surgery....... The problems with development and maintaining a large clinical registry are described and further studies are needed to validate data completeness. We consider the development of a national clinical registry for hip arthroscopy as a successful way of developing and maintaining a valuable clinical...

    The Danish Adoption Register was established in 1963-1964 to explore the genetic and environmental contribution to familial aggregation of schizophrenia. The register encompass information on all 14,425 non-familial adoptions of Danish children legally granted in Denmark 1924-1947. It includes name and date of birth of each adoptee and his or her biological and adoptive parents, date of transfer to adoptive parents and date of formal adoption. The linkage to biological and adoptive parents is close to complete, even biological fathers are registered for 91.4% of the adoptees. Adoption registers are a unique source allowing disentangling of genetic and familial environmental influences on traits, risk of diseases, and mortality.

    2014-12-21

    Esophageal atresia (EA) is defined as a discontinuity of the lumen of the esophagus repaired soon after birth. Dysphagia is a common symptom in these patients, usually related to stricture, dysmotility or peptic esophagitis. We present 4 cases of patients with EA who complained of dysphagia and the diagnosis of Eosinophilic esophagitis (EoE) was made, ages ranging from 9 to 16 years. Although our patients were on acid suppression years after their EA repair, they presented with acute worsening of dysphagia. Esophogastroduodenoscopy and/or barium swallow did not show stricture and biopsies revealed elevated eosinophil counts consistent with EoE. Two of 4 patients improved symptomatically with the topical steroids. It is important to note that all our patients have asthma and 3 out of 4 have tested positive for food allergies. One of our patients developed recurrent anastomotic strictures that improved with the treatment of the EoE. A previous case report linked the recurrence of esophageal strictures in patients with EA repair with EoE. Once the EoE was treated the strictures resolved. On the other hand, based on our observation, EoE could be present in patients without recurrent anastomotic strictures. There appears to be a spectrum in the disease process. We are suggesting that EoE is a frequent concomitant problem in patients with history of congenital esophageal deformities, and for this reason any of these patients with refractory reflux symptoms or dysphagia (with or without anastomotic stricture) may benefit from an endoscopic evaluation with biopsies to rule out EoE.

    Children with congenital esophageal atresia (EA) and tracheoesophageal fistula (TEF) have chronic respiratory symptoms including recurrent pneumonia, wheezing and persistent cough. The aim of this study is to describe the clinical findings of a large group of children with EA and TEF surgically corrected and the instrumental investigation to which they have undergone in order to better understand the patient's needs and harmonize the care. A retrospective data collection was performed on 105 children with EA and TEF followed at Department of Pediatric Medicine of Bambino Gesù Children's Hospital (Rome, Italy) between 2010 and 2015. 69/105 (66%) children reported lower respiratory symptoms with a mean age onset of 2.2 ± 2.5 years and only 63/69 (91%) performed specialist assessment at Respiratory Unit. Recurrent pneumonia (33%) and wheezing (31%) were the most reported symptoms. The first respiratory evaluation was performed after surgically correction of gastroesophageal reflux (GER) at mean age of 3.9 ± 4.2 years. Twenty nine patients have undergone to chest CT with contrast enhancement detecting localized atelectasis (41%), residual tracheal diverticulum (34%), bronchiectasis (31%), tracheal vascular compression (21%), tracheomalacia (17%) and esophageal diverticulum (14%). Fifty three patients have undergone to airways endoscopy detecting tracheomalacia (66%), residual tracheal diverticulum (26%), recurrent tracheoesophageal fistula (19%) and vocal cord paralysis (11%). Our study confirms that respiratory symptoms often complicate EA and TEF; their persistence despite medical and surgical treatment of GER means that other etiological hypothesis must be examined and that a complete respiratory diagnostic work up must be considered.

  13. Aspiration Risk and Respiratory Complications in Patients with Esophageal Atresia.

    Science.gov (United States)

    Kovesi, Thomas

    2017-01-01

    Chronic, long-term respiratory morbidity (CRM) is common in patients with a history of repaired congenital esophageal atresia, typically associated with tracheoesophageal fistula (EA/TEF). EA/TEF patients are at high risk of having aspiration, and retrospective studies have associated CRM with both recurrent aspiration and atopy. However, studies evaluating the association between CRM in this population and either aspiration or atopy have reported conflicting results. Furthermore, CRM in this population may be due to other related conditions as well, such as tracheomalacia and/or recurrent infections. Aspiration is difficult to confirm, short of lung biopsy. Moreover, even within the largest evidence base assessing the association between CRM and aspiration, which has evaluated the potential relationship between gastroesophageal reflux and asthma, findings are contradictory. Studies attempting to relate CRM to prior aspiration events may inadequately estimate the frequency and severity of previous aspiration episodes. There is convincing evidence documenting that chronic, massive aspiration in patients with repaired EA/TEF is associated with the development of bronchiectasis. While chronic aspiration is likely associated with other CRM in patients with repaired EA/TEF, this does not appear to have been confirmed by the data currently available. Prospective studies that systematically evaluate aspiration risk and allergic disease in patients with repaired EA/TEF and document subsequent CRM will be needed to clarify the causes of CRM in this population. Given the prevalence of CRM, patients with repaired EA/TEF should ideally receive regular follow-up by multidisciplinary teams with expertise in this condition, throughout both childhood and adulthood.

    Because many aspects of the management of esophageal atresia (EA) are still controversial, we evaluated the practice patterns of this condition across Europe. A survey was completed by 178 delegates (from 45 [27 European] countries; 88% senior respondents) at the EUPSA-BAPS 2012. Approximately 66% of respondents work in centers where more than five EA repairs are performed per year. Preoperatively, 81% of respondents request an echocardiogram, and only 43% of respondents routinely perform preoperative bronchoscopy. Approximately 94% of respondents prefer an open approach, which is extrapleural in 71% of respondents. There were no differences in use of thoracoscopy between Europeans (10%) and non-Europeans (11%, p = nonsignificant). Approximately 60% of respondents measure the gap intraoperatively. A transanastomotic tube (90%) and chest drain (69%) are left in situ. Elective paralysis is adopted by 56% of respondents mainly for anastomosis tension (65%). About 72% of respondents routinely request a contrast study on postoperative day 7 (2-14). Approximately 54% of respondents use parenteral nutrition, 40% of respondents start transanastomotic feeds on postoperative day 1, and 89% of respondents start oral feeds after postoperative day 5. Pure EA: 46% of respondents work in centers that repair two or more than two pure EA a year. About 60% of respondents opt for delayed primary anastomosis at 3 months (1-12 months) with gastrostomy formation without esophagostomy. Anastomosis is achieved with open approach by 85% of respondents. About 47% of respondents attempt elongation of esophageal ends via Foker technique (43%) or with serial dilations with bougies (41%). Approximately 67% of respondents always attempt an anastomosis. Gastric interposition is the commonest esophageal substitution. Many aspects of EA management are lacking consensus. Minimally invasive repair is still sporadic. We recommend establishment of an EA registry. Georg Thieme Verlag KG Stuttgart · New

    2004-09-15

    To gain more knowledge about dioxin levels, sources and emissions in Denmark, the Danish government year 2001 initiated the Danish Dioxin Monitoring Program. The program is a series of investigations, comprising soil, compost, percolate, bio-ash, incineration of municipal and hazardous waste, deposition, air, lake and fjord sediment as well as cows milk and human milk. The present paper describes the preliminary results for the continued investigation of air. Deposition of dioxin over land or sea is of major importance for the human exposure, which takes place mainly from food intake. The dioxin are emitted mainly to the atmosphere, therefore air measurements are well suited for tracking the transport and fate of dioxin from sources to exposure. Whereas measurements from chimneys has been frequently used to estimate the industrial emission from point sources such as incinerators, air measurements also include emission from diffuse sources such as larger urban or industrial regions, residential quarters, and from evaporation. Furthermore, emission measurements must be done on known sources, whereas air measurements include contribution from unknown source. The major drawbacks of air measurements are the long duration required (years), and the results depends on meteorological conditions, such as temperature, rainfall, wind speed and direction. The purpose of the present study has been to measure dioxins in Danish air, emphasizing - background concentrations and annual variation - difference between urban, rural and residential zones - influence from local sources and long range transport - connection between dioxin in air and deposition.

  18. Adult bile duct strictures: differentiating benign biliary stenosis from cholangiocarcinoma.

    2016-12-01

    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.

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

    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.

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.

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

    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

    This paper determines whether radiation therapy (RT) is a risk factor for infectious complications (particularly hepatic abscess formation) related to percutaneous biliary drainage (PBD). The authors retrospectively reviewed the charts of 98 consecutive patients who had undergone PBD for obstruction. In 34 patients with benign obstruction, three infectious complications occurred, none of which were hepatic abscess or fatal sepsis. In 39 patients who had malignant obstruction but did not have cholangiocarcinoma, 13 infectious complications occurred, including two hepatic abscesses and three cases of fatal sepsis. Of the 25 patients with cholangiocarcinoma, 15 underwent RT; in these 15 patients, 14 infectious complications occurred, including six hepatic abscesses and two cases of fatal sepsis

    Cervicovaginal atresia is a rare Mullerian anomaly. The management of cervicovaginal atresia has evolved from historical recommendations of hysterectomy to various reconstructive procedures more recently. The latter carries a risk of significant morbidity and unknown fertility. We present our experience in the management of this complex anomaly. Twenty patients with cervicovaginal atresia were operated in our hospital from January 2004 through December 2013. The details of their anatomical variations and functional outcomes were analyzed. Eighteen out of twenty patients had cervical agenesis. Two patients had cervical hypoplasia. All patients underwent utero-coloneovaginoplasty. Post operatively, all patients have regular menstrual cycles. One patient is married, sexually active and has satisfactory coital function. One patient had a bowel anastomotic leak that required a diversion ileostomy. Two patients developed mild stenosis. One patient has mild neovaginal mucosal prolapse. No patient has developed pyometra. Patients with cervicovaginal atresia need to be counselled about the various reconstructive options available and the potential risks. Social and economic factor play a significant role in determining the plan of management. For patients from conservative societies, utero-coloneovaginoplasty provides a safe conduit for the passage of menstrual flow and coitus, at the cost of permanent infertility.

    Full Text Available Our understanding of the post-transcriptional mechanisms involved in follicular atresia is limited; however, an important development has been made in understanding the biological regulatory networks responsible for mediating follicular atresia. MicroRNAs have come to be seen as a key regulatory actor in determining cell fate in a wide range of tissues in normal and pathological processes. Profiling studies of miRNAs during follicular atresia and development have identified several putative miRNAs enriched in apoptosis signaling pathways. Subsequent in vitro and/or in vivo studies of granulosa cells have elucidated the functional role of some miRNAs along with their molecular pathways. In particular, the regulatory roles of some miRNAs have been consistently observed during studies of follicular cellular apoptosis. Continued work should gradually lead to better understanding of the role of miRNAs in this field. Ultimately, we expect this understanding will have substantial benefits for fertility management at both the in vivo or/and in vitro levels. The stable nature of miRNA holds remarkable promise in clinical use as a diagnostic tool and in reproductive medicine to solve the ever-increasing fertility problem. In this review, we summarize current knowledge of the involvement of miRNAs in follicular atresia, discuss the challenges for further work and pinpoint areas for future research.

    Percutaneous biliary dilation was done in 3 patients with benign strictures. The first case was 50-year-old male who had multiple intrahepatic stones with biliary stricture. The second 46-year-old female and the third 25-year-old male suffered from recurrent cholangitis with benign stricture of anastomotic site after choledocho-jejunostomy. In the first case, a 6mm diameter Grunzing dilatation balloon catheter was introduced through the T-tube tract. In the second case, the stricture was dilated with two balloons of 5mm and 8mm in each diameter sequentially through the U-loop tract formed by surgically made jejunostomy and percutaneous transhepatic puncture. In the third case, the dilatation catheter was introduced through the percutaneous transhepatic tract. Dilatation was made with a pressure of 5 to 10 atmospheres for 1 to 3 minutes duration for 3 times. In all 3 cases, the strictures were successfully dilated and in second and third cases internal stent was left across the lesion for prevention of restenosis.

    Equol is a non-steroidal estrogen metabolite produced by microbial conversion of daidzein, a major soy isoflavone, in the gut of some humans and many animal species. Isoflavones and their metabolites can affect endogenous estradiol production, action, and metabolism, potentially influencing ovarian follicle function. However, no studies have examined the effects of equol on intact ovarian antral follicles, which are responsible for sex steroid synthesis and further development into ovulatory follicles. Thus, the present study tested the hypothesis that equol inhibits antral follicle growth, increases follicle atresia, and inhibits steroidogenesis in the adult mouse ovary. To test this hypothesis, antral follicles isolated from adult CD-1 mice were cultured with vehicle control (dimethyl sulfoxide; DMSO) or equol (600 nM, 6 μM, 36 μM, and 100 μM) for 48 and 96 h. Every 24 h, follicle diameters were measured to monitor growth. At 48 and 96 h, the culture medium was subjected to measurement of hormone levels, and the cultured follicles were subjected to gene expression analysis. Additionally, follicles were histologically evaluated for signs of atresia after 96 h of culture. The results indicate that equol (100 μM) inhibited follicle growth, altered the mRNA levels of bcl2-associated X protein and B cell leukemia/lymphoma 2, and induced follicle atresia. Further, equol decreased the levels of estradiol, testosterone, androstenedione, and progesterone, and it decreased mRNA levels of cholesterol side-chain cleavage, steroid 17-α-hydroxalase, and aromatase. Collectively, these data indicate that equol inhibits growth, increases atresia, and inhibits steroidogenesis of cultured mouse antral follicles. - Highlights: • Equol exposure inhibits antral follicle growth. • Equol exposure increases follicle atresia. • Equol exposure inhibits sex steroid hormone levels. • Equol exposure inhibits mRNA levels of certain steroidogenic enzymes.

    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

    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.

    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.

    The vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome are rare conditions. We aimed to present two cases with the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser co-occurrence from our local surgical center and through a systematic literature search detect published cases. Furthermore, we aimed to collect existing knowledge in the embryopathogenesis and genetics in order to discuss a possible link between the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome. Our first case was a white girl delivered by caesarean section at 37 weeks of gestation; our second case was a white girl born at a gestational age of 40 weeks. A co-occurrence of vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal defect, and limb defect association and Mayer-Rokitansky-Küster-Hauser syndrome was diagnosed in both cases. We performed a systematic literature search in PubMed ((VACTERL) OR (VATER)) AND ((MRKH) OR (Mayer-Rokitansky-Küster-Hauser) OR (mullerian agenesis) OR (mullerian aplasia) OR (MURCS)) without limitations. A similar search was performed in Embase and the Cochrane library. We added two cases from our local center. All cases (n = 9) presented with anal atresia and renal defect. Vertebral defects were present in eight patients. Rectovestibular fistula was confirmed in seven patients. Along with the uterovaginal agenesis, fallopian tube aplasia appeared in five of nine cases and in two cases ovarian involvement also existed. The co-occurrence of the vertebral defect, anal atresia, cardiac defect, tracheoesophageal fistula/esophageal atresia, renal

    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).

    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)

    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

    Percutaneous transhepatic catheter decompression is performed increasingly as an adjunct or alternative to surgery in patients with benign or malignant biliary obstruction. The authors recently saw three patients with cholangiocarcinoma in whom metastatic seeding of the peritoneal serosa was identified some months after initial percutaneous transhepatic biliary drainage. Although no tumor was found along the hepatic tract of the biliary drainage catheters to implicate the drainage tubes as the direct source of peritoneal spread, the occurrence of this rare type of metastasis of cholangiocarcinoma in patients with potential access of tumor cells to the peritoneal cavity via the catheter tracts does suggest such a relation. The clinical history of one patient is presented

    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.

  11. The effect of morphine on biliary dynamics

    International Nuclear Information System (INIS)

    Pedersen, S.A.; Oester-Joergensen, E.; Kraglund, K.

    1987-01-01

    The effect of morphine on biliary dynamics was studied by cholescintigraphy with 99m Tc-HIDA. Among 30 normals without morphine injection 3 did not demonstrate intestinal radioactivity after 1 h, whereas all visualized the gallbladder. Eight normals with morphine injection did not demonstrate intestinal radioactivity after 2 h, but all had gallbladder visualization very early. Variables of the time-activity curves from liver areas did not point to impaired uptake or excretion. Morphine-induced increase in resistance to passage from the common duct to the intestines in normals is of a magnitude that forces the total amount of bile to accumulate in the gallbladder. Results from 11 patients after cholecystectomy indicate that the increase in pressure is less than the maximal secretory pressure of the liver. The resorptive capacity and the compliance of the gallbladder enable these events to take place without signs of secondary liver impairment

    2016-08-01

    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.

    Background. Annular pancreas is an uncommon congenital abnormality, consisting of a flat band of pancreatic tissue, which encircles duodenum or extrahepatic biliary duct. We present a case of obstructive jaundice, caused by annular pancreas. Case report. A 46 years old female was admitted because of a sudden onset of abdominal pain, vomiting and jaundice. For the last six years she occasionally noticed her skin was light yellow, in the last year she felt distension in the upper abdomen, especially after fatty meals. Conclusions. Two US examinations, the first one six months before the admission, showed dilated hepatic ducts. The reason of dilatation was unclear, even after the endoscopic US examination. At operation an almost complete obstruction of the common hepatic duct was found, caused by a narrow band of pancreatic tissue. (author)

    Three patients are described with hepatic involvement by Echinococcus granulosus, complicated by spontaneous rupture into the biliary tract. Abdominal computed tomography, showing the cystic wall, the presence of wall calcifications, daughter cysts and wall enhancement, provided a correct diagnosis of hepatic hydatidosis in all patients. Dilatation of the bile ducts with the presence of intraluminal material was clearly shown by sonography and endoscopic retrograde cholangiography. On sonography, the intraluminal material appeared as amorphous, sludge-like hydatid sand, and as daughter cysts. On ERCP, the intrabiliary parasitic material appeared as non-homogeneous, irregularly shaped and mobile filling defects. Other findings at ERCP were displacement and distortion of intrahepatic bile ducts by the hepatic cysts and a mild dilatation of the pancreatic duct. (Auth.)

    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.

  16. Thyroid storm precipitated by acute biliary pancreatitis

    Full Text Available Thyroid storm is an acute, life-threatening exacerbation and sudden releasing large amounts of thyroid hormone in a short period of time. Nevertheless, critical aggravation of hyperthyroidism typically resulted from concurrent disorder. Synchronous management of thyroid storm along with its precipitant, such as infection is recommended. We described the case of an acute biliary pancreatitis complicated with a thyroid storm. The patient was successfully managed with a quick surgical intervention and further critical care for thyroid storm. Although it is widely believed that pancreatitis is seldom concurrent with thyrotoxicosis, thyroid storm can be precipitated by a variety of factors, including intra-abdominal infections such as acute pancreatitis or perforated peptic ulcer. In conclusion, acute pancreatitis in patients with thyrotoxicosis seems to be extremely rare, but such patients should be managed intensively against underlying thyroid disorders as well as pancreatitis.

  17. The post-traumatic biliary cyst

    Stellamor, K.; Hruby, W.; Stelzer, P.

    1982-01-01

    The case report communicated here illustrates a late complication subsequent to an emergency operation for liver rupture. This complication may result from ligating a branch of the hepatic artery to stop bleeding. If the necessary second operation is omitted for any reason, the hepatic sequester can develop into an abscess or a biliary cyst. It is to be expected that these late complications will occur more frequently in future owing to a probable increase in the incidence of the so-called blunt abdominal traumas. The reason for this is, on the one hand, the growing number of traffic accidents and, on the other hand, the increasing use of safety seat belts which tend to promote the occurrence of ruptures of the liver as part of the blunt abdominal traumas. However, we must emphasize that it is the use of safety seat belts only which ensures the traffic victims' chance of survival. (orig.) [de

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

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

  3. Role of stents and laser therapy in biliary strictures

    Chennupati, Raja S.; Trowers, Eugene A.

    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.

    Purpose: Dyslexia is a long lasting problem in learning to decode written words accurately and fluently. This definition suggests that dyslexia remains sufficiently constant to be assessed reliably with just one wide-range test across all educational levels. The current study investigated...... this possibility by asking whether students who receive special support in reading differ from other students on the same scale of decoding across all educational levels. Method: Decoding and spelling measures from a newly developed, web-based Danish dyslexia test were taken from 1564 students from Grade 3...... 9. Measures of decoding difficulties were reliably associated with current practices for referral to special support at all educational levels. On average, students receiving special support performed at the 5th percentile of the unselected groups. The results suggest that a wide-range test...

    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

    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.

    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.

    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.

    Imperforate hymen or atresia hymenalis is a rare clinical presentation, the condition is estimated to be present in 0.5\\/1000 females1. It is the most common obstructive anomaly of the female genital tract, and results from failure of canalization of the vaginal plate in utero. Atresia hymenalis can present in neonates as bulging hymen due to accumulation of secretions by the uterovaginal mucosa2,3. Usually the imperforate hymen is asymptomatic until menarche, when haematometrocolpos results in symptoms such as abdominal pain, abdominal mass, urinary retention and constipation. Many cases are diagnosed in the evaluation of primary amenorrhoea or recurrent abdominal pain2,3. We present 4 cases diagnosed over a 7 month period in our ED.

    Total 32 cases of pulmonary atresia were diagnosed radiographically at Seoul National University Hospital from March, 1979 to August 1982. Some characteristic radiological findings were analyzed in chest PA and cineangiographies. The results were as follows: 1. In the evaluation of chest PA, cardiomegaly was noticed in 16 cases, dextrocardia in 8 cases, elevated cardiac apex in 7 cases and right-sided aortic arch in 6 cases. The pulmonary vascularties were mildly decreased in 20 cases, markedly decreased in 9 cases and decreased with reticular pattern in 3 cases. 2. As final diagnoses after cineangiography, pulmonary atresia was associated with Tetralogy of Fallot variant in 17 cases, transposition of great vessels in 7 cases, single ventricle in 5 cases, tricuspid atresia in 2 cases and intact ventricular septum in 1 case. 3. The classification according to the pattern of pulmonary artery is main pulmonary trunk with PDA(Type Ia) in 10 cases, pulmonary arterial confluence with PDA (Type Ib) in 10 cases, no pulmonary arterial confluence with PDA (Type Ic) in 5 cases, main pulmonary trunk without PDA (Type IIa) in 0 case, pulmonary arterial confluence without PDA (Type IIb) in 5 cases, and no pulmonary arterial confluence without PDA ( Type IIc) in 2 cases. 4. Pulmonary wedge venography was done and successful in 8 cases. Among them, confluence between right and left pulmonary arteries was noticed in 5 cases. 5. Biventricular cineangiograpy and/or pulmonary wedge venography, if necessary, is essential for the accurate diagnosis of pulmonary atresia to demonstrate detailed anatomy of pulmonary artery.

    To introduce a new technique that combines laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft in patients with congenital atresia of the cervix. Video article introducing a new surgical technique. University hospital. A 16-year-old patient with congenital cervical atresia, vaginal dysgenesis, and ovarian endometrial cyst. An original technique of combined laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft for cervicovaginal reconstruction. A midline incision at the vaginal introitus was made, and a 9-cm canal was made between the bladder and the rectum using sharp and blunt dissection along the anatomic vaginal route, with the aid of laparoscopy to ensure correct orientation. A 14 × 12 cm split thickness skin graft was harvested from the right lateral thigh. By laparoscopy, the level of the lowest pole of the uterine cavity was exposed and the cervix was incised by shape dissection. The proximal segment of the harvested skin to the lower uterine segment was secured, and the distal segment was sutured with the upper margin of vulva vaginally. Surgical technique reports in anonymous patients are exempted from ethical approval by the Institutional Review Board. The patient gave consent to use the video in the article. The procedure was successfully completed. Since February 2013, our experiences of combined laparoscopic and vaginal cervicovaginal reconstruction using split thickness skin graft in 10 patients with congenital atresia of cervix were positive, with successful results and without complications or cervical, or vaginal stenosis. Our technique is feasible and safe for congenital atresia of cervix, with successful results and without complications or cervical or vaginal stenosis.

    Full Text Available Aim: The present study was aimed to assess the contractile status of neonatal small intestinal smooth muscle of dilated pre-atretic part of intestinal atresia to resolve debatable issues related to mechanisms of persistent dysmotility after surgical repair. Materials and Methods: A total of 34 longitudinally sectioned strips were prepared from pre-atretic dilated part of freshly excised 8 jejunal atresia type III a cases. Spontaneous as well as acetylcholine- and histamine-induced contractions were recorded in vitro by using organ bath preparations. Chemically evoked contractions were further evaluated after application of atropine (muscarinic blocker, pheniramine (H1 blocker, and lignocaine (neuronal blocker to ascertain receptors and neuronal involvement. Histological examinations of strips were made by using Masson trichrome stain to assess the fibrotic changes. Results: All 34 strips, except four showed spontaneous contractions with mean frequency and amplitude of 5.49 ± 0.26/min and 24.41 ± 5.26 g/g wet tissue respectively. The response to ACh was nearly twice as compared to histamine for equimolar concentrations (100 μM. ACh (100 μM induced contractions were attenuated (by 60% by atropine. Histamine (100 μM-induced contractions was blocked by pheniramine (0.32 μM and lignocaine (4 μM by 74% and 78%, respectively. Histopathological examination showed varying degree of fibrotic changes in muscle layers. Conclusions: Pre-atretic dilated part of jejunal atresia retains functional activity but with definitive histopathologic abnormalities. It is suggested that excision of a length of pre-atretic part and early stimulation of peristalsis by locally acting cholinomimetic or H1 agonist may help in reducing postoperative motility problems in atresia patients.

    Full Text Available Infants and children with esophageal atresia commonly present with swallowing dysfunction or dysphagia. Dysphagia can lead to a range of significant consequences such as aspiration pneumonia, malnutrition, dehydration, and food impaction. To improve oral intake, the clinical diagnosis of dysphagia in patients with esophageal atresia should focus on both the pharynx and the esophagus. To characterize the complex interactions of bolus flow and motor function between mouth, pharynx, and esophagus, a detailed understanding of normal and abnormal deglutition is required through the use of adequate and objective assessment techniques. As clinical symptoms do not correlate well with conventional assessment methods of motor function such as radiology or manometry but do correlate with bolus flow, the current state-of-the-art diagnosis involves high-resolution manometry combined with impedance measurements to characterize the interplay between esophageal motor function and bolus clearance. Using a novel pressure flow analysis (PFA method as an integrated analysis method of manometric and impedance measurements, differentiation of patients with impaired esophago-gastric junction relaxation from patients with bolus outflow disorders is clinically relevant. In this, pressure flow matrix categorizing the quantitative PFA measures may be used to make rational therapeutic decisions in patients with esophageal atresia. Through more advanced diagnostics, improved understanding of pathophysiology may improve our patient care by directly targeting the failed biomechanics of both the pharynx and the esophagus.

To characterize the complex interactions of bolus flow and motor function between mouth, pharynx, and esophagus, a detailed understanding of normal and abnormal deglutition is required through the use of adequate and objective assessment techniques. As clinical symptoms do not correlate well with conventional assessment methods of motor function such as radiology or manometry but do correlate with bolus flow, the current state-of-the-art diagnosis involves high-resolution manometry combined with impedance measurements to characterize the interplay between esophageal motor function and bolus clearance. Using a novel pressure flow analysis (PFA) method as an integrated analysis method of manometric and impedance measurements, differentiation of patients with impaired esophago-gastric junction relaxation from patients with bolus outflow disorders is clinically relevant. In this, pressure flow matrix categorizing the quantitative PFA measures may be used to make rational therapeutic decisions in patients with esophageal atresia. Through more advanced diagnostics, improved understanding of pathophysiology may improve our patient care by directly targeting the failed biomechanics of both the pharynx and the esophagus.

    Full Text Available Abstract Background Congenital cholesteatoma may be expected in abnormally developed ear, it may cause bony erosion of the middle ear cleft and extend to the infratemporal fossa. We present the first case of congenital cholesteatoma of the infratemporal fossa in a patient with congenital aural atresia that has been complicated with acute mastoiditis. Case presentation A sixteen year old Egyptian male patient presented with congenital cholesteatoma of the infratemporal fossa with congenital aural atresia complicated with acute mastoiditis. Two weeks earlier, the patient suffered pain necessitating hospital admission, magnetic resonance imaging revealed a soft tissue mass in the right infratemporal fossa. On presentation to our institute, Computerized tomography was done as a routine, it proved the diagnosis of mastoiditis, pure tone audiometry showed an air-bone gap of 60 dB. Cortical mastoidectomy was done for treatment of mastoiditis, removal of congenital cholesteatoma was carried out with reconstruction of external auditory canal. Follow-up of the patient for 2 years and 3 months showed a patent, infection free external auditory canal with an air-bone gap has been reduced to 35db. One year after the operation; MRI was done and it showed no residual or recurrent cholesteatoma. Conclusions Congenital cholesteatoma of the infratemporal fossa in cases of congenital aural atresia can be managed safely even if it was associated with mastoiditis. It is an original case report of interest to the speciality of otolaryngology.

    The benefits of bone-anchored hearing devices (BAHD) in children with unilateral aural atresia are controversial. We sought to determine whether there is parental decisional conflict surrounding elective placement of BAHD for this indication. Caregivers of pediatric patients with unilateral aural atresia and normal contralateral ear undergoing percutaneous BAHD consultation were enrolled. All consultations were carried out by one pediatric otolaryngologist in a consistent manner. After consultation, the participants completed a demographics form and the Decisional Conflict Scale (DCS) questionnaire. Twenty-three caregivers of 15 male (65.2%) and 8 female (34.8%) children (mean age 5.65 years) participated. The overall median DCS score was 15.63 (standard error = 4.21). Significant decisional conflict (DCS score ≥ 25) was found in 10 participants (43.5%). The median DCS score in the group choosing surgery was 5.47, and it was 23.44 in those who did not choose surgery (Mann-Whitney U = 39, Z = -1.391, P = .164). The median DCS score for mothers and fathers was 25 and 3.91, respectively. Many parents experienced significant decisional conflict when considering percutaneous BAHD surgery in children with unilateral aural atresia in our study population. Future research should explore the impact of decisional conflict on health outcomes. © The Author(s) 2015.

    Down syndrome is an autosomal chromosome disorder, characterized by intellectual disability and muscle hypotonia. Muscle hypotonia is observed from neonates to adulthood in Down syndrome patients, but muscle hypertonicity is extremely unusual in this syndrome. During a study period of nine years, we found three patients with severe spastic quadriplegia among 20 cases with Down syndrome and congenital duodenal stenosis/atresia (3/20). However, we could find no patient with spastic quadriplegia among 644 cases with Down syndrome without congenital duodenal stenosis/atresia during the same period (0/644, P quadriplegia among 17 patients with congenital duodenal stenosis/atresia without Down syndrome admitted during the same period to use as a control group (0/17, P quadriplegia in patients with Down syndrome. Long-term survival is improving, and the large majority of people with Down syndrome are expected to live well into adult life. Management and further study for the various problems, representing a low prevalence but serious and specific to patients with Down syndrome, are required to improve their quality of life. © 2012 The Authors.

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

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

    AIM: To clarify the strategy for early diagnosis of pancreaticobiliary maljunction (PBM) without biliary dilatation and to pathologically examine gallbladder before cancer develops. METHODS: The anatomy of the union of the pancreatic and bile ducts was assessed by using endoscopic retrograde cholangiopancreatography (ERCP). Patients with a long common channel in which communication between the pancreatic and bile ducts was maintained even during sphincter contraction were diagnosed as having PBM. Of these, patients in which the maximal diameter of the bile duct was less than 10 mm were diagnosed with PBM without biliary dilatation. The process of diagnosing 54 patients with PBM without biliary dilatation was retrospectively investigated. Histopathological analysis of resected gallbladder specimens from 8 patients with PBM without biliary dilatation or cancer was conducted. RESULTS: Thirty-six PBM patients without biliary dilatation were diagnosed with gallbladder cancer after showing clinical symptoms such as abdominal or back pain (n = 16) or jaundice (n = 12). Radical surgery for gallbladder cancer was only possible in 11 patients (31%) and only 4 patients (11%) survived for 5 years. Eight patients were suspected as having PBM without biliary dilatation from the finding of gallbladder wall thickening on ultrasound and the diagnosis was confirmed by ERCP and/or magnetic resonance cholangiopancreatography (MRCP). The median age of these 8 patients was younger by a decade than PBM patients with gallbladder cancer. All 8 patients underwent prophylactic cholecystectomy and bile duct cancer has not occurred. Wall thickness and mucosal height of the 8 resected gallbladders were significantly greater than controls, and hyperplastic changes, hypertrophic muscular layer, subserosal fibrosis, and adenomyomatosis were detected in 7 (88%), 5 (63%), 7 (88%) and 5 (63%) patients, respectively. Ki-67 labeling index was high and K-ras mutation was detected in 3 of 6 patients

    The authors reviewed the clinical charts and the radiographic files of 93 patients with obsructive jaundice -in 86 cases due to neoplasms -treated with PTBD. The test of differences from survival curves was used to identify the clinical parameters predictive of short survival after PTBD. The difference in survival curves was significant relative to serum indirect bilirubin (cut point: 7.6 mg%), to serum cholinesterase (cut point: 1290 mU/ml), to white blood cells counts (cut point: 8600/mm 3 ), to blood urea nitrogen (BUN) levels (cut point: 60 mg%). Because of the market negative prognostic value of high BUN levels, our data seemto indicate that PTBD should not be performed when severe renal insufficiency is present. Other parameters correlated with a short survival after PTBD were the histotype of metastasis (in comparison with the other ones) and in large neoplastic volume (in comparison with a small and medium ones). Through pre-PTBD radiological and laboratory data analysis, a group of patients can be selected in whom the procedure will increase neither well-being nor survival, as plotted against those patients who are likely to benefit from biliary drainage

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

    In Denmark biogas is produced from several different types of facilities: Anaerobic industrial waste and waste water treatment plants, anaerobic sludge stabilization plants, landfill gas plants and single farm and centralized biogas plants. Centralized biogas plants account for approximately 40% of the total production of biogas. In the recent 5 years the single farm plant technology has been considerably improved. Standardized concepts has been developed, which have decreased the construction price of single farm plants, and the introduction of dual fuel gas engines has lowered the cost and increased the efficiency of the energy production unit. Dual fuel gas engines use 7-10% diesel oil together with the gas. They are based on diesel engine principles, often they are modified standard diesel engines, which are cheaper and more simple than ignition gas engines. The construction cost for a typical single farm plant with a 150-200 m{sup 3} reactor is 200,000 USD. As the farmer can obtain a 30% funding from the Danish Energy Agency, the net cost for the farmer is 134,000 USD. The annual income if manure and some industrial waste in co-digested is around 30,000-35,000 USD and the annual running costs is in the level of 5,000-6,000 USD. (EG)

    To evaluate usefulness of a manipulation catheter in percutaneous transhepatic biliary drainage (PTBD). A biliary manipulation catheter was used for the aspiration of retained bile and lesion crossing during an initial PTBD in 91 consecutive patients over a 6 month period. This catheter allowed for a 0.035 inch guide wire made of 5F short steel braided polyurethane. The terminal 1 cm segment was tapered and 45 degree angulated. Two side holes were made in the terminal segment to facilitate the aspiration of bile. The safety of this procedure was evaluated based on whether the catheters caused complications during insertion and manipulation, and whether cholangitis was aggravated after the procedure. Effectiveness of the procedure was evaluated based on the ability to aspirate retained bile and to cross the lesion. Both the insertion of a 0.035 inch hydrophilic guide wire and aspiration of sufficient retained bile were successful with the catheter. Crossing the common bile duct (CBD) lesion had a 98.1% success rate during the initial PTBD. Crossing the hilar obstruction lesion was had a 94.7% success rate to the CBD and 92.1% to the contralateral lobe. Cholangitis improved in 97% of cases, and aggravated transiently in only 3% of cases after PTBD.
