    BACKGROUND: Intrahepatic biliary cystadenocarcinoma (IBC) is a low-incidence disease which is often mis-diagnosed because of insufifcient recognition. This study aimed to investigate the clinical features, diagnosis and treatment of the disease. METHOD: The clinical data of 4 IBC patients treated in the Second Afifliated Hospital of Sun Yat-Sen University were retrospectively analyzed. RESULTS: The 4 patients complained of right upper abdominal pain and mass or masses. One patient presented with moderate fever and chills, and two had moderately impaired liver function. The levels of carbohydrate antigens (CA125 and CA19-9) were signiifcantly elevated and the level of carcinoembryonic antigen was slightly elevated in 3 patients. The level of serum transaminase was elevated in 2 patients, and the level of serum total bilirubin elevated in 2. Intrahepatic cystic masses ranging from 5.0 to 20.5 cm in diameter were found in all patients by ultrasound and CT/MR scan. Three of the 4 patients were misdiagnosed on admission as having hepatic cyst and one as having hepatic abscess. Radical removal of masses was performed in three patients after pathological diagnosis. One patient died from tumor recurrence 7 years after operation, 2 were followed up for 12 and 17 months without evidence of recurrence. The high risk patients who received palliative therapy were closely followed up. CONCLUSIONS: The diagnosis of IBC without speciifc clinical features mainly depends on imaging and pathological examination. Increased levels of serum CA125 and CA19-9 might contribute to the diagnosis and prognosis of some IBC patients. Radical excision is the only effective treatment.

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

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

    This study describes the first case of biliary peritonitis after radiofrequency ablation diagnosed by magnetic resonance (MR) imaging with gadolinium ethoxybenzyl diethylenetriaminepentaacetic acid (Gd-EOB-DTPA), a hepatocyte-specific MR imaging contrast agent. The image acquired 300 minutes after the administration of Gd-EOB-DTPA was useful to make a definite diagnosis and to identify the pathway of bile leakage. It is important to decide on the acquisition timing with consideration of the predicted location of bile duct injury.

    A pulmonary mucinous cystadenocarcinoma is an extremely rare tumor that is considered to be a cystic variant of mucin-producing lung adenocarcinoma. We present a case of pulmonary mucinous cystadenocarcinoma in a 54-year-old woman. Chest CT scans showed a 4.3-cm-sized, lobulated, well-defined, and homogeneous mass in the right middle lobe with peripheral stippled calcifications that demonstrated low-attenuation with no enhancement after contrast administration; 18F-fluorodeoxyglucose (FDG) PET/CT demonstrated mild heterogeneous FDG uptake. The mass was diagnosed as adenocarcinoma with mucin production by transbronchial lung biopsy. Right middle lobectomy was performed, and the pathologic examination disclosed a pulmonary mucinous cystadenocarcinoma.

  9. Scintigraphic hepatobiliary function studies in newborn infants to diagnose biliary hypoplasia or atresia

    International Nuclear Information System (INIS)

    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)

    AIM: To determine the impact (morbidity/mortality) of biliary stent-related events (SRE) (cholangitis or stent obstruction) in chemotherapy-treated pancreatico-biliary patients. METHODS: All consecutive patients with advanced pancreatobiliary cancer and a biliary stent in-situ prior to starting palliative chemotherapy were identified retrospectively from local electronic case-note records (Jan 13 to Jan 15). The primary end-point was SRE rate and the time-to-SRE (defined as time from first stenting before chemotherapy to date of SRE). Progression-free survival and overall survival were measured from the time of starting chemotherapy. Kaplan-Meier, Cox and Fine-Gray regression (univariate and multivariable) analyses were employed, as appropriate. For the analysis of time-to-SRE, death was considered as a competing event. RESULTS: Ninety-six out of 693 screened patients were eligible; 89% had a metal stent (the remainder were plastic). The median time of follow-up was 9.6 mo (range 2.2 to 26.4). Forty-one patients (43%) developed a SRE during follow-up [cholangitis (39%), stent obstruction (29%), both (32%)]. There were no significant differences in baseline characteristics between the SRE group and no-SRE groups. Recorded SRE-consequences were: none (37%), chemotherapy delay (24%), discontinuation (17%) and death (22%). The median time-to-SRE was 4.4 mo (95%CI: 3.6-5.5). Patients with severe comorbidities (P < 0.001) and patients with ≥ 2 baseline stents/biliary procedures [HR = 2.3 (95%CI: 1.2-4.44), P = 0.010] had a shorter time-to-SRE on multivariable analysis. Stage was an independent prognostic factor for overall survival (P = 0.029) in the multivariable analysis adjusted for primary tumour site, performance status and development of SRE (SRE group vs no-SRE group). CONCLUSION: SREs are common and impact on patient’s morbidity. Our results highlight the need for prospective studies exploring the role of prophylactic strategies to prevent/delay SREs. PMID

    BACKGROUND:Cystadenocarcinoma of the pancreas is insensitive to radiotherapy and chemotherapy, and surgery is at present the deifnitive treatment. Early and accurate diagnosis of cystadenocarcinoma is crucial for increasing the ifve-year survival rate and the resectable rate. There is no deifnitive and effective method of early diagnosis of cystadenocarcinoma of the pancreas in China and other countries. METHODS: We compared endoscopic ultrasonography-guided (EUS-guided) ifne needle aspiration biopsy combined with cyst lfuid carcinoembryonic antigen (CEA), CA19-9 examination with computed tomography (CT), B-ultrasonography (B-US) and serum CEA and CA19-9, to explore methods of early diagnosis of cystadenocarcinoma of the pancreas. Retrospective analysis was made on the clinical data of 126 cases of benign pancreatic lesion (90 cases) and cystadenocarcinoma (36). RESULTS: The sensitivity of B-US and CT for cystadeno-carcinoma was 52.8%and 77.8%, while the speciifcity was 78.9%and 86.7%, respectively. When measurement of CEA and CA19-9 of cyst lfuid was combined with EUS-guided ifne needle aspiration biopsy, the sensitivity was 94.4%, higher than that of B-US and CT (P CONCLUSIONS: EUS-guided ifne needle aspiration biopsy combined with examination of cyst lfuid CEA, CA19-9 is a credible means for early diagnosis of cystadenocarcinoma of the pancreas. B-US, CT and serum CEA, CA19-9 measurements are in common use, their ifndings are also very important.

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

    Hepatobiliary cystadenomas (HBC) and cystadenocarcinomas are rare cystic lesions. Most patients with these lesions are asymptomatic, but presentation with obstructive jaundice may occur. The first patient presented with intermittent colicky pain andrecurrent obstructive jaundice. Imaging studies revealed a polypoid lesion in the left hepatic duct. The second patient had recurrent jaundice and cholangitis. Endoscopic retrograde cholangiopancreatography (ERCP) showed a cystic lesion at the confluence of the hepatic duct. In the third patient with intermittent jaundice and cholangitis, cholangioscopy revealed a papillomatous structure protruding into the left bile duct system. In the fourth patient with obstructive jaundice, CT-scan showed slight dilatation of the intrahepatic bile ducts and dilatation of the common bile duct of 3 cm. ERCP showed filling of a cystic lesion. All patients underwent partial liver resection, revealing HBC in the specimen. In the fifth patient presenting with obstructive jaundice, ultrasound examination showed a hyperechogenic cystic lesion centrally in the liver. The resection specimen revealed a hepatobiliary cystadenocarcinoma.HBC and cystadenocarcinoma may give rise to obstructive jaundice. Evaluation with cross-sectional imaging techniques is useful. ERCP is a useful tool to differentiate extraductal from intraductal obstruction.

    The presenting clinical features of a series of cases of biliary tract ascariasis are described, in particular the characteristic colicky pain which occurs. The term 'ascaritic biliary pain' is introduced for the symptom diagnostic of live Ascaris adult worms inside the biliary passages. Methods of diagnosis before, and in the course of, operation are discussed and seem adequate. The management of worms discovered in the bile ducts, and those in the proximal small bowel, is described.

    Endoscopic management of biliary obstruction has evolved tremendously since the introduction of flexible fiberoptic endoscopes over 50 years ago. For the last several decades, endoscopic retrograde cholangiopancreatography(ERCP) has become established as the mainstay for definitively diagnosing and relieving biliary obstruction. In addition, and more recently, endoscopic ultrasonography(EUS) has gained increasing favor as an auxiliary diagnostic and therapeutic modality in facilitating decompression of the biliary tree. Here, we provide a review of the current and continually evolving role of gastrointestinal endoscopy, including both ERCP and EUS, in the management of biliary obstruction with a focus on benign biliary strictures.

    Full Text Available A rare case of mucinous adenocarcinoma of the cecum in a pregnant woman is described. A 32-year-old Korean woman was diagnosed as having an abdominal tumor immediately after giving birth. Abdominal computed tomography demonstrated a smooth mass measuring 10 cm in diameter on the right side of the abdomen. Acute abdomen developed 3 days after birth. At emergency surgery, volvulus of a polypoid tumor was detected at the cecum apart from the normal appendix. We successfully performed a tumorectomy; however, histopathological examination demonstrated mucinous adenocarcinoma with a massive blood clot.

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

    2013-01-01

    Objective To discuss the clinical value of serum procalcitonin level in diagnosing biliary tract infection. Methods A total of 53 patients with obstructive jaundice were enrolled in this study. The serum procalcitonin level was determined in all patients by immunolofluoreseence sandwich method. Percutanous biliary drainage was performed in all patients. Based on the bile culture result and the clinical manifestations, the patients were divided into the bacterial infection group (n = 33) and the non-bacterial infection group (n = 20). The serum procalcitonin level, white blood cell (WBC) count and the percentage of neutrophilic granulocyte were determined, and the results were compared between the two groups. Results Taking 0.25 ng/ml as the positive threshold of serum procalcitonin level, the sensitivity and the specificity for the diagnosis of biliary tract bacterial infection were 91.9% and 87.5% respectively. When WBC of 8.89 × 109/L was taken as the positive threshold, the sensitivity and the specificity for the diagnosis of biliary tract bacterial infection were 54.8% and 83.3% respectively. If neutrophilic granulocyte of 74.25% was regarded as the positive threshold, the sensitivity and the specificity for the diagnosis of biliary tract bacterial infection were 66.1% and 70.8% respectively. The serum procalcitonin level in the bacterial infection group was significantly higher than that in the non-bacterial infection group (P < 0.05). Conclusion Determination of serum procalcitonin level is very helpful for the diagnosis of biliary tract bacterial infection with much higher sensitivity and specificity. Therefore, serum procalcitonin level can be used as an effective index for biliary tract bacterial infection.%目的 探讨血清降钙素原(PCT)浓度在胆道感染中的诊断价值.方法 采用荧光免疫夹心法检测53例梗阻性黄疸患者血清PCT浓度,所有患者均行经皮经肝穿刺胆管引流术,根据胆汁培养结果及临床症状

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

  3. Cytomorphological findings and histological correlation of papillary cystadenocarcinoma of the parotid: Not always a low-grade tumor

    Directory of Open Access Journals (Sweden)

    Yasmeen Khatib

    2016-01-01

    Full Text Available Papillary cystadenocarcinoma (PCAC is a rare salivary gland tumor characterized by a predominantly cystic growth that often exhibits intraluminal papillary growth without specific histologic features of other cystic salivary gland tumors. The preoperative cytological diagnosis can pose a diagnostic challenge as it has to be differentiated from other cystic papillary tumors such as mucoepidermoid carcinoma, papillary cystic variant of acinic cell carcinoma, and low-grade cribriform CAC. It is considered to be a low-grade malignant salivary gland tumor with an indolent biological behavior. We report a case of PCAC of the parotid in a 55-year-old male diagnosed on fine needle aspiration cytology. Although it showed mild atypia cytologically, on excision tumor showed vascular and perineural invasion with regional node metastasis indicating a wider morphologic spectrum than what is described. This prompted us to write a case report describing the cytological and histological features of this rare tumor and also discuss the diagnostic challenges.

    The diagnosis of cystadenoma is rare, even more so when located in the extrahepatic bile duct. Unspecific clinical signs may lead this pathology to be misdiagnosed. The need for pathological anatomy in order to distinguish cystadenomas from simple biliary cysts is crucial. The most usual treatment nowadays is resection of the bile duct, together with cholecystectomy and Roux-en-Y reconstruction.

    BACKGROUND: Currently adopted diagnostic methods for duodenal-biliary and pancreaticobiliary relfuxes carry many lfaws, so the incidence of the two relfuxes demands further larger sample size studies. This study aimed to evaluate Western blotting for the diagnosis of relfuxes in biliary diseases. METHODS: An oral radionuclide 99mTc-DTPA test (radio-nuclide, RN) was conducted for the observation of duodenal-biliary relfux prior to measuring bile radioactivity and Western blotting for detecting bile enterokinase (EK). Pancreaticobiliary relfux was assessed by biochemical and Western blotting tests for biliary amylase activity and trypsin-1, respectively. In accordance with bile sample origin, our samples were classiifed into ductal bile and gall bile groups;based on each individual biliary disease, we further classiifed the ductal bile group into ifve sub-groups, and the gall bile group into four sub-groups. Western blotting was conducted to assess the two relfuxes in biliary diseases. RESULTS: Consistencies were noted between EK and RN tests when diagnosing duodenal-biliary relfux (P0.05); in the common bile duct cyst group, the EK positive rate was signiifcantly lower than the trypsin-1 positive rate (P CONCLUSIONS: Western blotting can accurately relfect duodenal-biliary and pancreaticobiliary relfuxes. EK has greater sensitivity than RN for duodenal-biliary relfux. The majority of biliary amylase and lipase comes from the pancreas in all biliary diseases;pancreaticobiliary relfux is the predominant source in the common bile duct cyst group and duodenal-biliary relfux is responsible for the ductal pigment stone group.

    For the purpose of the precise diagnosis and proper treatment planning of obstructive jaundice, various techniques to obtain tissues from biliary stricture sites have been proposed. We performed percutaneous transcatheter biopsy of biliary strictures with a biotome in six patients with obstructive jaundice. The site of biliary stricture were distal common bile ducts (n=1), and confluence of both intrahepatic ducts (n=2). Their histologic diagnose were adenocarcinoma (n=2), chronic choleochitis (n=3), and atypical cell suspicious of malignancy (n=1). False positive or false negative results were not documented by other means (including laparotomy), when regarding atypical cell suspicious of malignancy as true positive for malignancy. Percutaneous transcatheter biliary biopsy with a biotome is easy to perform in conjunction with percutaneous transhepatic biliary drainage procedure, and can be able to obtain specific tissue for correct diagnosis.

    Full Text Available Cystadenocarcinoma is regarded as a rare adenocarcinoma variant in animals. This work reports the case of an 8-year-old female Poodle dog with salivary gland cystadenocarcinoma with morphological characteristics similar to a hemangiosarcoma. Histopathological analysis showed a tumor mass with cystic formations containing a large amount of red blood cells. In order to distinguish these two entities, periodic acid Schiff (PAS staining and immunohistochemical analysis were carried out with the use of cytokeratin AE1/AE3 (CK and CD31-specific antibodies. Neoplastic cells were PAS-negative, CK-positive and CD31-negative confirming their epithelial origin. Based on the findings, the diagnosis of high grade cystadenocarcinoma was established.

    AIM: To investigate the eligible management of the cystic neplasms of the liver.METHODS: The charts of 9 patients who underwent surgery for intrahepatic biliary cystic liver neoplasms between 2003 and 2008 were reviewed retrospectively. Informed consent was obtained from the patients and approval was obtained from the designated review board of the institution.RESULTS: All patients were female with a median(range) age of 49 (27-60 years). The most frequent symptom was abdominal pain in 6 of the patients. Four patients had undergone previous laparotomy (with otherdiagnoses) which resulted in incomplete surgery or recurrences. Liver resection (n=6) or enucleation (n=3) was performed. The final diagnosis was intrahepatic biliary cystadenoma in 8 patients and cystadenocarcinoma in 1 patient. All symptoms resolved after surgery.There has been no recurrence during a median (range)31 (7-72) mo of follow up.CONCLUSION: In spite of the improvement in imagingmodalities and increasing recognition of biliary cystadenoma and cystadenocarcinoma, accurate preoperative diagnosis may be difficult. Complete surgical removal(liver resection or enucleation) of these lesions yields satisfying long-term results.

    Full Text Available Abstract Background Primary adenocarcinomas of the appendix are uncommon. Mucoceles that result from mucinous adenocarcinomas of the appendix may be incidentally detected on imaging. Case presentation A case of a mucocele of the appendix, due to cystadenocarcinoma, is presented as an incidental imaging finding in a female, 86-year-old patient. The patient was admitted due to rectal hemorrhage and underwent colonoscopy, x-ray, US and CT. Adenocarcinoma of the ascending colon, adenomatous polyp of the sigmoid colon and a cystic lesion in the right iliac fossa were diagnosed. The cystic lesion was characterized as mucocele. The patient underwent right hemicolectomy, excision of the mucocele and sigmoidectomy. She recovered well and in two-year follow-up is free from cancer. Conclusions Preoperative diagnosis of an underlying malignancy in a mucocele is important for patient management, but it is difficult on imaging studies. Small lymph nodes or soft tissue stranding in the surrounding fat on computed tomography examination may suggest the possibility of malignancy.

    A 64 year-old male, was diagnosed with obstructive jaundice due to a well-differentiated pancreatic neuroendocrine tumor with liver metastases. The patient underwent endoscopic placement of covered self-expanding biliary stent (10x60 mm, Hanaro) by ERCP. He was admitted with cholangitis one year later. The following ERCP revealed a fractured stent with loss of the distal end (duodenal) and partial migration of the remaining stent to the common bile duct. The fragmented stent was removed from the common bile duct and a new, similar one was inserted. Four months later the patient was admitted with cholangitis. A new ERCP was done and biliary stent was also fragmented. It was removed and an uncovered stent (Wallflex) was inserted. PMID:27065248

    Epithelial ovarian tumors are the most common malignant ovarian neoplasms and, in most cases, eventual rupture of such tumors is associated with a surgical procedure. The authors report the case of a 54-year-old woman who presented with spontaneous rupture of ovarian cystadenocarcinoma documented by computed tomography, both before and after the event. In such cases, a post-rupture staging tends to be less favorable, compromising the prognosis. (author)

  14. Biliary cystadenoma with bile duct communication depicted on liver-specific contrast agent-enhanced MRI in a child

    International Nuclear Information System (INIS)

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

    The role of preoperative biliary drainage (PBD) in patients with distal or proximal biliary obstruction secondary to resectable tumors has been a matter for debate. A review of the literature using Medline, Embase and Cochrane databases was undertaken for studies evaluating routes of drainage (endoscopic or percutaneous) and stent types (plastic or metal) in patients with resectable disease. Preoperative biliary drainage is indicated for relief of symptomatic jaundice, cholangitis, patients undergoing neoadjuvant therapy or those patients where surgery may be delayed. Endoscopic methods are preferred over percutaneous methods because of lower complication rates. In patients with proximal biliary obstruction, PBD should be guided by imaging studies to aid in selective biliary cannulation for unilateral drainage in order to reduce the risk of cholangitis in undrained liver segments.

    2003-01-01

    AIM: To summarize the characteristics of patients suffered from primary biliary cirrhosis associated with ulcerative colitis.METHODS: To report a new case and review the literature.RESULTS: There were 18 cases (including our case) of primary biliary cirrhosis complicated with ulcerative colitis reported in the literature. Compared with classical primary biliary cirrhosis, the patients were more often males and younger similar. The bowel lesions were usually mild with proctitis predominated. While ulcerative colitis was diagnosed before primary biliary cirrhosis in 13 cases, the presentation of primary biliary cirrhosis was earlier than that of ulcerative colitis in our new case reported here. The prevalence of primary biliary cirrhosis among patients of ulcerative colitis was almost 30 times higher than in general population.CONCLUSION: Association of primary biliary cirrhosis with ulcerative colitis is rare. It should be considered in the differential diagnosis of hepatobiliary disease in patients with ulcerative colitis, and vice versa.

    Decompression of the biliary system in patients with malignant biliary obstruction has been widely accepted and implemented as part of the care. Despite a wealth of literature, there remains a significant amount of uncertainty as to which approach would be most appropriate in different clinical settings. This review covers stenting of the biliary system in cases of resectable or palliative malignant biliary obstruction, potential candidates for biliary drainage, technical aspects of the procedure, as well as management of biliary stent dysfunction. Furthermore, periprocedural considerations including proper mapping of the location of obstruction and the use of antibiotics are addressed. PMID:26431598

    The aim of this paper was to describe functional biliary syndromes and methods for evaluation of the biliary tract in these patients. Functional biliary symptoms can be defined as biliary symptoms without demonstrable organic substrate. Two main syndromes exist: Gallbladder dysfunction and sphincter of Oddi dysfunction. The most important investigative tools are cholescintigraphy and endoscopic sphincter of Oddi manometry. In gallbladder dysfunction a scintigraphic gallbladder ejection fraction below 35% can select patients who will benefit from cholecystectomy. Endoscopic sphincter of Oddi manometry is considered the gold standard in sphincter of Oddi dysfunction but recent development in scintigraphic methods is about to change this. Thus,calculation of hilum-to-duodenum transit time and duodenal appearance time on cholescintigraphy have proven useful in these patients. In conclusion, ambient methods can diagnose functional biliary syndromes.However, there are still a number of issues where further knowledge is needed. Probably the next step forward will be in the area of sensory testing and impedance planimetric methods.

    Pancreatic cancer and cholangiocarcinoma are the most common causes of malignant biliary obstruction. They are diseases of increasing incidence and unfavorable prognosis. Only patients with localized disease indicated for surgery have a chance of long-term survival. These patients represent less than 20 % of all patients, despite the progress in our diagnostic abilities.Locally advanced and metastatic tumors are treated with palliative chemotherapy or chemoradiotherapy; the results of such treatments are unsatisfactory. The average survival of patients with unresectable disease is 6 months and only 5-10 % of patients survive 5 years.Biliary drainage is an integral part of palliative treatment. Endoscopically or percutaneosly placed stents improve quality of life, decrease cholestasis and pruritus, but do not significantly improve survival. Biliary stents get occluded over time, possibly resulting in acute cholangitis and require repeated replacement.Photodynamic therapy and radiofrequency ablation, locally active endoscopic methods, have been increasingly used in recent years in palliative treatment of patients with malignant biliary obstruction. In photodynamic therapy, photosensitizer accumulates in tumor tissue and is activated 48 hours later by light of a specific wave length. Application of low voltage high frequency current during radiofrequency ablation results in tissue destruction by heat. Local ablation techniques can have a significant impact in a large group of patients with malignant biliary obstruction, leading to improved prognosis, quality of life and stent patency.

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

  4. Percutaneous biliary drainage in acute suppurative cholangitis with biliary sepsis

    International Nuclear Information System (INIS)

    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

    Ascaris lumbricoides is a worldwide intestinal infestation that may cause various complications. Biliary ascariasis, however, is a rare condition. We describe a child with biliary ascariasis. The patient's clinical symptoms were pain, vomiting and abdominal tenderness, and she was thought to have acute appendicitis. However, laboratory examination revealed high serum alkaline phosphatase and amylase levels, and ultrasonography and percutaneous cholangiography demonstrated biliary ascariasis. The patient was successfully treated with mebendazole and antispasmolytic drugs.

  9. Ultrasonographic findings of type IIIa biliary atresia

    International Nuclear Information System (INIS)

    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.

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.Keywords: plastic stents, self-expandable metal stents, drug eluting stents, bioabsorbable stents, malignant biliary strictures, benign biliary strictures

    2006-01-01

    Tuberculosis (TB) is a very rare cause of biliary stricture that is difficult to diagnose and usually requires surgical intervention in order to rule out underlying malignant etiology. We report a 56-year-old man presented with jaundice, weight loss and poor appetite. Initial work up showed the dilated biliary system secondary to distal common bile duct stricture. Investigations to define the etiology of this stricture showed inconclusive brush cytology with absent abdominal masses and lymph nodes but enlarged mediastinal lymph nodes. Biopsy from these lymph nodes showed a non-caseating epitheliod granuloma with negative acid fast bacilli (AFB) stain.The patient had a dramatic response to empirical antituberculosis therapy. Six weeks later, culture from lymph nodes was positive for Mycobacterium tuberculosis.Three months later, follow-up cholangiogram showed complete resolution of the stricture with normalization of liver enzymes 6 mo after starting anti-tuberculosis therapy. Treatment was continued for 12 mo and the patient had a normal life with normal liver enzymes and regression of the mediastinal lymph nodes at the time when he was reported in this paper.Although 16 cases of tuberculous biliary stricture are available in the English literature, up to our knowledge,this is the second published report of tuberculous biliary stricture, which resolved completely after medical therapy alone and the second reported case from the Middle East. This report emphasizes the importance of keeping TB as a possibility of biliary stricture in this part of the world.

    2010-01-01

    BACKGROUND: Biliary leak is an uncommon but signiifcant complication following cholecystectomy. Endotherapy is an established method of treatment. However, the optimal intervention is not known. METHOD: Eighty-ifve patients with postcholecystectomy biliary leaks from July 2000 to March 2009 were retrospectively evaluated. RESULTS: The study population was 20 males and 65 females with a mean age of 42.47 years. Patients presented with abdominal pain (46), jaundice (23), fever (23), abdominal distension (42), or bilious abdominal drain (67). Endoscopic retrograde cholangiopancreatography detected a leak at the cystic duct stump in 45 patients, stricture with middle common bile duct leak in 4, leak from the right hepatic duct in 3, and a ligated common bile duct in 32. Twelve also had bile duct stones. One had a broken T-tube with stones. Endotherapy was possible in 53 patients. Three patients with stones, one with a broken T-tube with stones, and 4 with stricture of the common bile duct with a leak were managed with sphincterotomy and stenting. Eight patients with a cystic duct stump leak with stones were managed with sphincterotomy and stone extraction. Three outpatients and 12 inpatients with a cystic duct stump leak were managed with sphincterotomy and stent and sphincterotomy and nasobiliary drain, respectively. Five patients with a cystic duct stump leak were managed with stenting. Sixteen with coagulopathy were managed with only nasobiliary drain (9) or stent (7). Leak closure was achieved in 100%patients. Four developed mild pancreatitis which improved with conservative treatment. CONCLUSIONS: Endoscopic intervention is a safe and effective method of treatment of postcholecystectomy biliary leaks. However, management should be individualized based on factors such as outpatients or inpatients, presence of stone, stricture, ligature, or coagulopathy.

    Full Text Available Context Biliary atresia is a progressive, idiopathic, fibro-obliterative disease of the extrahepatic biliary tree that pre­sents with biliary obstruction exclusively in the neonatal period. Objectives To assess the differences regarding age at referral, age at surgery, duration of propaedeutics and waiting time for surgery between two groups of infants in different periods. Methods Retrospective study of infants diagnosed with biliary atresia on two periods: 1983-1993 and 1998-2011. Results Biliary atresia was diagnosed in 129 infants, being 48 in casuistic I and 81 in casuistic II. The median age at admission was 94 and 60 days, respectively (P = 0.0001. On evaluating patients who had undergone portoenterostomy before 120 days of age, no difference was observed regarding the duration of propaedeutics or waiting time for surgery (P = 0.15, but difference was found when comparing the age at surgery (P = 0.002. Among those infants with no biliary flow and without liver transplantation or death after 18 post-operative months, the estimated probability of survival was 44.6% and 38.7% in casuistics I and II, respectively. In casuistic I, all infants who showed biliary flow were alive during the observation period and, in casuistic II, 80.3% were alive after 7 years of follow-up. Conclusions Even though patients were admitted and treated earlier, it is clear that surgery could be done sooner. Delay in referral and timely propaedeutics were the main contributors.

    Extrahepatic cholangiocarcinoma, including hilar cholangiocarcinoma, is a relatively rare diagnosis. However, it frequently has been associated with major problems in diagnostics and clinical management from its first comprehensive description by Klatskin up until today. In this article, cholangiocarcinoma, representing the most common biliary tumor, as well as the differential diagnoses of benign and malignant biliary obstruction, will be discussed. The latest improvements of cross-sectional imaging modalities (sonography, CT, MRI and PET) and their diagnostic values for detection and staging will be displayed. A practical imaging-based diagnostic approach to obstructive biliary disease will be proposed. (orig.)

    This study studied the use of ERCP and nasobiliary tube in the diagnosis of fungal infection of biliary tract and the efficacy of combined use of local administration via nasobiliary tube and intravenous antifungal treatment for severe biliary tract fungal infection. 5 patients in our series,with age ranging from 47 to 68 y (mean 55.8), were diagnosed as having mixed bacterial and fungal infection of biliary tract as confirmed by smear or/and culture of bile obtained by ERCP and nasobiliary drainage. Besides routine anti-bacteria therapy, all patients received local application of fluconazole through nasobiliary tube and intravenous administration of fluconazole or itraconazole in terms of the results of in vitro sensitivity test. The mean duration of intravenous fluconazole or itraconazole was 30 days (24-40 days), and that of local application of fluconazole through nasobiliary drainage tube was 19 days (8-24 days). During a follow-up period of 3-42 months, all patient's fungal infection of biliary tract was cured. It is concluded that on the basis of typical clinical features of biliary tract infection, fungal detection of smear/culture of bile obtained by ERCP was the key for the diagnosis of fungal infection of biliary tract. Local application antifungal drug combined with intravenous anti-fungal drugs might be an effective and safe treatment for fungal infection of biliary tract.

    Bates, M D; Bucuvalas, J C; Alonso, M H; Ryckman, F C

    1998-01-01

    Biliary atresia is a disorder of infants in which there is obliteration or discontinuity of the extrahepatic biliary system, resulting in obstruction of bile flow. Untreated, the resulting cholestasis leads to progressive conjugated hyperbilirubinemia, cirrhosis, and hepatic failure. Biliary atresia has an incidence of approximately one in 10,000 live births worldwide. Evidence to date supports a number of pathogenic mechanisms for the development of biliary atresia. An infectious cause, such as by a virus, would seem most pausible in many cases. The clinical observation that biliary atresia is rarely encountered in premature infants would support an agent acting late in gestation. However, no infectious or toxic agent has been conclusively implicated in biliary atresia. Genetic mechanisms likely play important roles, even regarding susceptibility to other specific causes, but no gene whose altered function would result in obstruction or atresia of the biliary tree has been identified. The variety of clinical presentations support the notion that the proposed mechanisms are not mutually exclusive but may play roles individually or in combination in certain patients. Biliary atresia, when untreated, is fatal within 2 years, with a median survival of 8 months. The natural history of biliary atresia has been favorably altered by the Kasai portoenterostomy. Approximately 25 to 35% of patients who undergo a Kasai portoenterostomy will survive more than 10 years without liver transplantation. One third of the patients drain bile but develop complications of cirrhosis and require liver transplantation before age 10. For the remaining one third of patients, bile flow is inadequate following portoenterostomy and the children develop progressive fibrosis and cirrhosis. The portoenterostomy should be done before there is irreversible sclerosis of the intrahepatic bile ducts. Consequently, a prompt evaluation is indicated for any infant older than 14 days with jaundice to

    Full Text Available Background: Biliary cast syndrome (BCS was a postoperative complication of orthotopic liver transplantation (OLT, and the reason for BSC was considered to relate with ischemic type biliary lesions. This study aimed to evaluate the relationship between BCS following OLT and the hepatic artery resistance index (HARI, and to observe pathological changes and morphology of biliary casts. Methods: Totally, 18 patients were diagnosed with BCS by cholangiography following OLT using choledochoscope or endoscopic retrograde cholangiopancreatography. In addition, 36 patients who did not present with BCS in the corresponding period had detectable postoperative HARI on weeks 1, 2, 3 shown by color Doppler flow imaging. The compositions of biliary casts were analyzed by pathological examination and scanning electron microscopy. Results: HARI values of the BCS group were significantly decreased as compared with the non-BCS group on postoperative weeks 2 and 3 (P 1 (OR = 1.300; 1.223; and 1.889, respectively. The OR of HARI 3 was statistically significant (OR = 1.889; 95% confidence interval = 1.166-7.490; P = 0.024. The compositions of biliary casts were different when bile duct stones were present. Furthermore, vascular epithelial cells were found by pathological examination in biliary casts. Conclusions: HARI may possibly serve as an independent risk factor and early predictive factor of BCS. Components and formation of biliary casts and bile duct stones are different.

    Primary mucinous cystadenocarcinoma (MCA) of the breast is a rare but pathologically distinct breast tumor. There have been some case reports on primary MCA of the breast; however, they have all focused on pathologic findings. Here, we report the radiologic findings of two cases of MCA along with a review of the literature. Breast MCA shows a circumscribed mass with some calcifications on mammography, an intracystic solid mass without increased vascularity or a vascular stalk on ultrasound, and a heterogeneously enhancing mass within a rim-enhancing cyst with intermediate signal intensity on T2-weighted magnetic resonance imaging. These radiologic findings and the presence of mucin in the percutaneous biopsy specimen should suggest the possibility of MCA in the differential diagnosis of a breast tumor. PMID:27721884

    Primary mucinous cystic neoplasms are rare tumours of the kidney, with a very few case reports in the literature. They arise from metaplasia of renal pelvic urothelium. We describe here a 45-year-old male who presented with pain in the abdomen and a lump in the left iliac fossa for two months. Ultrasound and CT scan showed a large, complex, heterogenous mass in the central abdomen and left iliac fossa, suggesting the possibility of dermoid cyst. Excision of the mass showed an enlarged multicystic kidney filled with mucin, destruction of renal parenchyma and a small viable area of grey white tumour. Histopathology revealed a peripherally located mucinous cystadenocarcinoma arising in the background of chronic pyelonephritis and mucinous metaplasia. We report this case for the rarity of the lesion and the associated clinical and radiological diagnostic dilemma.

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

  10. The role of ultrasound and magnetic resonance cholangiopancreatography for the diagnosis of biliary stricture after liver transplantation

    International Nuclear Information System (INIS)

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

  12. Primary biliary cirrhosis

    2008-01-01

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

  13. Percutaneous biliary drainage and stenting

    International Nuclear Information System (INIS)

    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

    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.

    Biliary pain without obvious biliary obstruction is common in postcholecystectomy patients. We studied 20 symptomatic patients with episodes of biliary-type pain after cholecystectomy (all having undergone endoscopic retrograde cholangiography), and in 18 asymptomatic postcholecystectomy controls. We performed quantitative hepatobiliary radionuclide analysis with dimethyl-imidodiacetic acid. From a series of 90 dynamic images at 1-min intervals using a gamma camera coupled to a computer, time-activity curves were produced in regions of interest in the liver, intrahepatic biliary tree, common duct, and heart, from which quantitative biliary excretion indexes were obtained. The results demonstrate a biliary kinetic dysfunction in patients with postcholecystectomy pain without morphological abnormalities. PMID:1995268

  1. 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.

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

    Full Text Available Abstract Low-grade cribriform cystadenocarcinoma (LGCCA is a rare tumor of the salivary gland that exhibits clinically indolent behavior. In this paper, we present a case of invasive adenocarcinoma of the accessory parotid gland in a young male that exhibited histology suggestive of an association of LGCCA. A 27-year-old man presented with a subcutaneous tumor in his left cheek. The tumor was separated from the parotid gland and located on the masseter muscle. The tumor was resected, and the postoperative histological diagnosis was adenocarcinoma, not otherwise specified (ANOS. The tumor exhibited papillary-cystic and cribriform proliferation of the duct epithelium and obvious stromal infiltration. Some tumor nests were rimmed by myoepithelium positive for smooth muscle actin, p63, and cytokeratin 14, indicating the presence of intraductal components of the tumor. Tumor cells exhibited mild nuclear atypia, and some of them presented an apocrine-like appearance and had cytoplasmic PAS-positive/diastase-resistant granules and hemosiderin. Other cells had foamy cytoplasm with microvacuoles. Immunohistochemistry revealed that the almost all of the tumor cells were strongly positive for S-100. These histological findings suggest the possibility that ANOS might arise secondarily from LGCCA. This is an interesting case regarding the association between ANOS and LGCCA in oncogenesis.

    Many advances have been achieved in biliary stenting over the past 30 years. Endoscopic stent placement has become the primary management therapy to relieve obstruction in patients with benign or malignant biliary tract diseases. Compared with plastic stents, a self-expandable metallic stent (SEMS) has been used for management in patients with malignant strictures because of a larger lumen and longer stent patency. Recently, SEMS has been used for various benign biliary strictures and leaks. ...

    The role of urgent endoscopic retrograde cholangiopancreatography (ERCP) in acute biliary pancreatitis is for many years a subject for disagreement among physicians. Although the evidence seemed to be in favor of performing ERCP, endoscopists usually hesitate to conform to the guidelines. ERCP is an invasive procedure, with complications which can affect patients’ outcome. Recent evidence suggests that we should probably modify our policy, recruiting less invasive procedures, like magnetic re...

    The records of 22 patients with cancers of extrahepatic biliary passages (EHBP) were analyzed to understand their natural histories and patterns of failure and to evaluate the effectiveness of various treatments. None of the preoperative investigations consistently defined the entire extent of tumor. Percutaneous transhepatic cholangiography (PTHC) was the most helpful (100%) in accurately defining the site of ductal obstruction. Computed tomography was helpful in diagnosing liver metastases in 53% and primary tumor mass in 23% of patients. The most common sites of tumor failure or persistence were: liver (67%), tumor bed (56%), peritoneum (22%), porta hepatis and lymph nodes (17%). The median survival for the entire group was 6.8 months. Surgery plays an important role in managing these tumors and in defining tumor extent for subsequent adjuvant irradiation. Patients receiving radiation doses greater than or equal to 70 TDF had a longer median survival (11 months) than patients receiving less than 70 TDF (4.4 months). All three patients, who were alive and free of disease greater than 1 year, received radiation doses greater than or equal to 70 TDF. From the data, it is difficult to comment on the effectiveness of chemotherapy. The authors have made suggestions regarding radiation volume and doses to various structures. The need for entering these patients into multi-institutional clinical trials is stressed.

  11. Endoscopic management of biliary complications after liver transplantation: An evidence-based review.

    2015-06-10

    Biliary tract diseases are the most common complications following liver transplantation (LT) and usually include biliary leaks, strictures, and stone disease. Compared to deceased donor liver transplantation in adults, living donor liver transplantation is plagued by a higher rate of biliary complications. These may be promoted by multiple risk factors related to recipient, graft, operative factors and post-operative course. Magnetic resonance cholangiopancreatography is the first-choice examination when a biliary complication is suspected following LT, in order to diagnose and to plan the optimal therapy; its limitations include a low sensitivity for the detection of biliary sludge. For treating anastomotic strictures, balloon dilatation complemented with the temporary placement of multiple simultaneous plastic stents has become the standard of care and results in stricture resolution with no relapse in > 90% of cases. Temporary placement of fully covered self-expanding metal stents (FCSEMSs) has not been demonstrated to be superior (except in a pilot randomized controlled trial that used a special design of FCSEMSs), mostly because of the high migration rate of current FCSEMSs models. The endoscopic approach of non-anastomotic strictures is technically more difficult than that of anastomotic strictures due to the intrahepatic and/or hilar location of strictures, and the results are less satisfactory. For treating biliary leaks, biliary sphincterotomy and transpapillary stenting is the standard approach and results in leak resolution in more than 85% of patients. Deep enteroscopy is a rapidly evolving technique that has allowed successful treatment of patients who were not previously amenable to endoscopic therapy. As a result, the percutaneous and surgical approaches are currently required in a minority of patients. PMID:26078829

    AIM: To clarify the pathogenesis of biliary dilatation associated with anomalous union of the pancreatic and biliary ducts (AUPBD).METHODS: Direct cholangiopancreatograms of 350 adult patients with or with suspicion of hepatobiliary or pancreatic disorders were reviewed. AUPBD was diagnosed cholangiopancreatographically, when the pancreaticobiliary ductal union was located above the narrow distal segment of the bile duct, which represents the action of the sphincter of Oddi. The narrow portion of the terminal choledochus was defined as symmetrical stricture of the common bile duct just above the pancreaticobiliary ductal union.RESULTS: AUPBD was found in 36 patients. Among cholangiopancreatographic features, the narrow portion of the terminal choledochus was the most pathognomonic for AUPBD (accuracy, 98%); it was present in 29 (81%)patients with AUPBD, but was not found in any patients without AUPBD. Among patients with AUPBD, biliary dilatation (>10 mm) was more frequent in those with the narrow portion of the terminal choledochus (23/29)than in those without (2/7; P = 0.018) AUPBD. Among the patients with both AUPBD and the narrow portion of the terminal choledochus, there was a strong negative correlation between the minimum diameter of the narrow portion and the maximum diameter of the choledochus (r = -0.78, P<0.001), suggesting that the degree of biliary narrowing at the narrow portion correlates with that of upstream biliary dilatation.CONCLUSION: The narrow portion of the terminal choledochus, a pathognomonic radiologic feature of AUPBD, may be a cause of biliary dilatation in patients with AUPBD.

    2015-11-01

    Primary sclerosing cholangitis (PSC) is a premalignant biliary tract disease that confers a significant risk for the development of cholangiocarcinoma (CCA). The chronic biliary tract inflammation of PSC promotes pro-oncogenic processes such as cellular proliferation, induction of DNA damage, alterations of the extracellular matrix, and cholestasis. The diagnosis of malignancy in PSC can be challenging because inflammation-related changes in PSC may produce dominant biliary tract strictures mimicking CCA. Biomarkers such as detection of methylated genes in biliary specimens represent noninvasive techniques that may discriminate malignant biliary ductal changes from PSC strictures. However, conventional cytology and advanced cytologic techniques such as fluorescence in situ hybridization for polysomy remain the practice standard for diagnosing CCA in PSC. Curative treatment options of malignancy arising in PSC are limited. For a subset of patients selected by using stringent criteria, liver transplantation after neoadjuvant chemoradiation is a potential curative therapy. However, most patients have advanced malignancy at the time of diagnosis. Advances directed at identifying high-risk patients, early cancer detection, and development of chemopreventive strategies will be essential to better manage the cancer risk in this premalignant disease. A better understanding of dysplasia definition and especially its natural history is also needed in this disease. Herein, we review recent developments in our understanding of the risk factors, pathogenic mechanisms of PSC associated with CCA, as well as advances in early detection and therapies.

    AIA:To correlate the significance of liver biochemical tests in diagnosing post orthotopic liver transplantation (OLT) biliary complications and to study their profile before and after endoscopic therapy.METHODS: Patients who developed biliary complications were analysed in detail for the clinical information,laboratory tests, treatment offered, response to it,follow up and outcomes. The profile of liver enzymes was determined. The safety, efficacy and outcomes of endoscopic retrograde cholangiography (ERC) were also analysed.RESULTS: 40 patients required ERC for 70 biliary complications. GGT was found to be > 3 times (388.1± 70.9 U/mL vs 168.5 ± 34.2 U/L, P = 0.007) and SAP > 2 times (345.1 ± 59.1 U/L vs152.7 ± 21.4 U/L, P =0.003) the immediate post OLT values. Most frequent complication was isolated anastomotic strictures in 28 (40%).Sustained success was achieved in 26 (81%) patients.CONCLUSION: Biliary complications still remain an important problem post OLT. SAP and GGT can be used as early, non-invasive markers for diagnosis and also to assess the adequacy of therapy. Endoscopic management is usually effective in treating the majority of these biliary complications.

    @@INTRODUCTION It is axiomatic that the most effective and soundly based plan of treatment of any disorder is one aimed at the mechanism or mechanisms responsible for its development[1]. This basic notion, coupled with recent reports[2- 11] in which, surprisingly there is a total lack of reference to the probable involvement of autonomic-arc-reflexes in the physiopathogenesis of biliary acute pancreatitis have prompted this presentation. Undoubtedly, this disease entity has numerous causes, an obscure physiopathology, few effective remedies, and, often, an unpredictable outcome. At the turn of the century, Opie[12,13] brought to light the association between gallstone migration and acute pancreatitis.

    Caroli's disease, which is a rare condition with congenital dilatation if the intrahepatic bile ducts, is usually diagnosed postoperatively. The clinical suspicion in a patient with gallstones and choledocholithiasis presenting with dilated intrahepatic biliary radicles and jaundice is usually an obstructive etiology. However, scintigraphic evaluation of this entity, as in this case, gives additional information on liver function, biliary drainage and predisposing conditions like Caroli's disease, which could be missed otherwise

    Multiplanar reconstruction (MPR) of helical computed tomography (HCT) was performed on 54 patients, including 27 patients with obstructive jaundice, and its usefulness in diagnosing biliary tract disease was evaluated. Ultrasonography (US) was also performed in all patients. HCT-MPR was able to delineated the upper, middle and lower bile duct in 100%, 100% and 98.1% of the cases, respectively. Biliary stenosis was diagnosed by HCT-MPR with an accuracy of 96.3%. The differential diagnosis of biliary stenosis was established correctly with an accuracy of 63.0% using US, compared with 83.3% using axial images of HCT (HCT-Axial). However, the diagnostic accuracy for rate of choledocholithiasis was 87.5% with HCT-MPR, 95.8% with HCT-Axial, and 76% with US. The overall accuracy of HCT-MPR was 88.9% in case of obstructive jaundice. The result was superior to that obtained with HCT-Axial (81.5%). In conclusion, HCT-MPR is useful for follow-up examination after ultrasonography in patients suspected of having biliary tract diseases. (author)

    AIM: To evaluate the imaging findings of biliary hamartomas (von Meyenburg complexes, VMCs) and discuss the differential diagnosis with other related diseases.METHODS: Imaging findings of biliary hamartomas on ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), MR cholangiopancreatography (MRCP)and hepatobiliary scintigraphy were retrospectively analyzed in six patients.RESULTS: On ultrasound images, five of the six cases showed multiple small hyper- and hypo-echoic lesions with comet-tail echoes, especially when magnified by US with the usage of zoom function. In all the six cases,multiple tiny hypodense lesions less than 10 mm in diameter were revealed as scattered throughout the liver with no enhancement on CT. These tiny lesions were demonstrated to be hyper- and hypo-intensity on T2- and TI-weighed images, respectively, in three patients who underwent MRI examinations. MRCP was performed in two patients, and clearly showed multiple tiny irregular- and round-shaped hyper-intensity lesions.MRCP and hepatobiliary scintigraphy showed normal appearances of intra- and extra-hepatic bile ducts in two and one patients, respectively.CONCLUSION: Imaging modalities are useful in the diagnosis and differential diagnosis of VMCs. A correct diagnosis might be obtained when typical imaging findings are present even without a histological confirmation.

    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.

    The objectives of this review are to outline the recent findings related to the morphological heterogeneity of the biliary epithelium and the heterogeneous pathophysiological responses of different sized bile ducts to liver gastrointestinal hormones and peptides and liver injury/toxins with changes in apoptotic, proliferative and secretory activities. The knowledge of biliary function is rapidly increasing because of the recognition that biliary epithelial cells (cholangiocytes) are the targets of human cholangiopathies, which are characterized by proliferation/damage of bile ducts within a small range of sizes. The unique anatomy, morphology, innervation and vascularization of the biliary epithelium are consistent with function of cholangiocytes within different regions of the biliary tree. The in vivo models [e.g., bile duct ligation (BDL), partial hepatectomy, feeding of bile acids,carbon tetrachloride (CCl4) or α-naphthylisothiocyanate (ANIT)] and the in vivo experimental tools [e.g., freshly isolated small and large cholangiocytes or intrahepatic bile duct units (IBDU) and primary cultures of small and large murine cholangiocytes] have allowed us to demonstrate the morphological and functional heterogeneity of the intrahepatic biliary epithelium.These models demonstrated the differential secretory activities and the heterogeneous apoptotic and proliferative responses of different sized ducts. Similar to animal models of cholangiocyte proliferation/injury restricted to specific sized ducts, in human liver diseases bile duct damage predominates specific sized bile ducts.Future studies related to the functional heterogeneity of the intrahepatic biliary epithelium may disclose new pathophysiological treatments for patients with cholangiopathies.

    Biliary drainage with biliary stent placement is the treatment of choice for palliation in patients with malignant biliary obstruction caused by unresectable neoplasms. In such patients, the endoscopic approach can be initially used with percutaneous radiological intervention.

    AIM: CT virtual endoscopy has been used in the study of various organs of body including the biliary tract, however,CT virtual endoseopy in diagnosis of gallbladder polyps has not yet been reported. This study was to evaluate the diagnostic value of CT virtual endoscopy in polyps of the gallbladder.METHODS: Thirty-two cases of gallbladder polyps were examined by CT virtual endoscopy, ultrasound, CT scan with oral biliary contrast separately and confirmed by operation and pathology. CT biliary cystoscopic findings were analyzed and compared with those of ultrasound and CT scan with oral biliary contrast, and evaluated in comparison with operative and pathologic findings in all cases.RESULTS: The detection rate of gallbladder polyps was 93.8%(90/96), 96.9%(93/96) and 79.2%(76/96) for CT cystoscopy, ultrasound and CT scan with oral contrast,respectively. CT biliary cystoscopy corresponded well with ultrasound as well as pathology in demonstrating the location, size and configuration of polyps. CT endoscopy was superior to ultrasound in viewing the polyps in a more precise way, 3 dimensionally from any angle in space, and showing the surface in details. CT biliary cystoscopy was also superior to CT scan with oral biliary contrast in terms of observation of the base of polyps for the presence of a pedicle, detection rates as well as image quality. The smallest polyp detected by CT biliary cystoscopy was measured 1.5 mmx2.2 mmx2.5 mm.CONCLUSION: CT biliary cystoscopy is a non-invasive and accurate technique for diagnosis and management of gallbladder polyps.

    Introduction: Recently, multidetector computed tomography (MDCT) has been introduced into clinical practice. MDCT has become the noninvasive diagnostic test of choice for detailed evaluation of biliary obstruction. Aim: the main objective of the present study was to evaluate the diagnostic value of MDCT compared to invasive procedures for detecting biliary obstruction causes. Material and Methods: Since February 2009 until May 2011 fifty biliary obstruction patients based on clinical, laboratory or ultrasonographic findings, were evaluated by Multidetector-row computed tomography. The causes of biliary obstruction, which was identified using. MDCT were classified into three categories: calculus, benign stricture, and malignancy. Final diagnosis was conducted based on percutaneous transhepatic cholangiography (PTC), endoscopic retrograde cholangiopancreatography, biopsy, or surgery. The MDCT diagnosis and were compared with the final diagnosis. Results: A correct diagnosis of causes of biliaryobstruction was made on the basis of MDCT findings for 44 of the total 50 patients. Two patients with chronic pancreatitis were incorrectly diagnosed with a pancreatic head adenocarcinoma on the basis of MDCT findings. One patient with biliary stone was incorrectly diagnosed with a periampullary adenocarcinoma on the basis of MDCT findings. The Sensitivity, specificity and accuracy of MDCT in the diagnosis of causes of biliary obstruction were 94.12% and87.87% and94.6% respectively. Conclusion: Based on the findings of this study MDCT has an excellent image quality, providing valuable information about the biliary tree and other abdominal organs. The use of advanced image processing, including maximum intensity projection and multiplanar reconstruction (especially coronal or sagittal reformatted images), allows superior visualization of the biliary tree and vascular structures. Three-dimensional reconstruction images complement axial images by providing a more anatomically

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

    Background There is increasing interest in the microbiome of the hepatobiliary system. This study investigated the influence of infection with the fish-borne liver fluke, Opisthorchis felineus on the biliary microbiome of residents of the Tomsk region of western Siberia. Methodology/Principal Findings Samples of bile were provided by 56 study participants, half of who were infected with O. felineus, and all of who were diagnosed with gallstone disease. The microbiota of the bile was investigated using high throughput, Illumina-based sequencing targeting the prokaryotic 16S rRNA gene. About 2,797, discrete phylotypes of prokaryotes were detected. At the level of phylum, bile from participants with opisthorchiasis showed greater numbers of Synergistetes, Spirochaetes, Planctomycetes, TM7 and Verrucomicrobia. Numbers of > 20 phylotypes differed in bile of the O. felineus-infected compared to non-infected participants, including presence of species of the genera Mycoplana, Cellulosimicrobium, Microlunatus and Phycicoccus, and the Archaeans genus, Halogeometricum, and increased numbers of Selenomonas, Bacteroides, Rothia, Leptotrichia, Lactobacillus, Treponema and Klebsiella. Conclusions/Significance Overall, infection with the liver fluke O. felineus modified the biliary microbiome, increasing abundance of bacterial and archaeal phylotypes. PMID:27447938

    Full Text Available Purpose: The use of laparoscopy in the treatment of biliary atresia (BA is still debated. We report our strategy using laparoscopy in type I cystic BA. Materials and Methods: We reviewed the records of patients treated for BA from 2002-2013. When the diagnosis was suspected, an ultrasound was performed. If it showed a cyst > 5 mm in the hilum with no patent gallbladder, we performed an initial explorative laparoscopy. In the case of a patent biliary tree above the cyst, a laparoscopic cystojejunostomy was performed. In cases of absent communication (type III, conversion and portoenterostomy were performed. Pre and postoperative data and overall survival rate with the native liver were reviewed. Results: Forty-four children were treated for BA. Six presented with a cystic form diagnosed by US. Three children had type I BA; three had type III BA. No postoperative complications were noted. Median follow-up was 62.2 months (22.7-93.5. One patient died of a cardiac malformation. The five remaining patients are alive with their native liver. Of the 38 treated for noncystic BA, 16 were transplanted. Conclusion: We confirmed the prognosis of cystic BA, which is less severe than noncystic BA. Our strategy using laparoscopy allowed for the confirmation and qualification of the type of BA. In type I, complete treatment by laparoscopy has been performed safely.

    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.

    Summary: Simulating physiological neuronal and hormonal conditions during digestive and interdigestive periods, the study identified the changes of the motility of biliary system including bile duct and sphincter of Oddi (SO) before and after cholecystojejunostomy. Thirty-five rabbits were divided into five groups randomly. The experimental groups received the venous injection of CCK 10 ng/kg, ery thromycin 10 mg/kg, atropine 3 μg/kg and L-NAME 10 mg/kg respectively. Each rabbit under went manometry through introducing a three-lumen catheter via the papilla retrogradely, using the low-compliance papillary infusion system. Then the gallbladder and the upper segment of the jejunum was anastomosed and the manometric procedures repeated after one week. SO basal pressure was in creased, contraction amplitude decreased, contraction time shortened after cholecystojejunostomy. L-NAME, CCK and erythromycin could all excite SO. L-NAME could increase basal pressure and con traction amplitude, CCK increase basal pressure contraction amplitude and frequency, and ery-thromycin increase contraction amplitude, respectively. But comparing with that before cholecystoje junostomy, the increasing extent was decreased. The tensional and spontaneous contractions of the SO were under the control of the neural and hormonal mechanism. The anastomosis of gallbladder and jejunum and the drainage of bile made the tensional contraction stronger, but the spontaneous contraction weakened after the operation due to the decreases of the sensitivity of SO to hormonal fac tors. The clinical symptoms may not be relieved when the patients with SO dysfunction accepted cholecystojejunostomy.

  8. THE ACTUALLY PRINCIPLES IN THE TREATMENT OF BILIARY OBSTRUCTION FROM EXTRAHEPATIC BILE DUCTS CANCER

    Full Text Available The most common type of extrahepatic bile ducts cancer is the proximal segment which include the bifurcation of common hepatic duct (Klatskin’s tumors. The diagnosis of these kinds of tumors is always challenging. Magnetic resonance cholangiopancreatography (MRCP is the best imagistic procedure also for diagnosis and for staging. Surgical resection provides the best chance for cure in patients with biliary malignancy; unfortunately only 30% from patients with Klatskin’s tumors are diagnosed in resectable stages. The type and extension of the resection depends of the tumor stage and site. Resection of the biliary duct associated with hepatectomy and/or pancreaticoduodenectomy (performed especially for limphadenectomy has good results, from point of view of disease-free survival. In selected cases, the extrahepatic bile duct resection alone and hepatico-jejunal anastomosis is also considered as curative resection. Portal vein resection may be performed and can improve the prognosis. Palliative procedures of nonresectable bile ducts cancer consist in surgical by-pass, percutaneous biliary drainage and endoscopic endoprosthesis. Because long-term relief of jaundice is difficult without using biliary stenting, a combination of radiation therapy and stent placement is commonly used. As radiation therapy, external-beam radiotherapy is usually performed, but combined use of intraluminal brachytherapy with external beam radiation therapy is more useful for making the treatment more effective. Radiation therapy can be associated with chemotherapy (gemcitabine in unresectable bile duct cancer to extend survival and improve quality of life.

  9. Treatment of malignant stenosis of biliary tract with introduction of percutaneous selfexpandible metallic stent

    International Nuclear Information System (INIS)

    On a case of a female patients with malignant biliary stenosis the author presents his first experiences with selfexpandible metallic stent. The main indications of percutaneous insertion of stents are inoperable malignant biliary stenoses. In this case, there was an inoperable ventricular carcinoma with metastatic involvement of porta hepatitis and left lobe of the liver with extrahepatic bile duct stenosis, diagnosed by ERCP (endoscopic retrograde cholangio-pancreaticography) USG (ultrasonography) and PTC (percutaneous transhepatic cholangiography). Despite of repeated attempts the endoscopic internal drainage has failed. Because of malignant jaundice - PTC had been performed and just then, PTBD (percutaneous transhepatic biliary drainage) without direst communication between the biliary tree and duodenum. Twelve days after the procedure we performed an external-internal (combinated) drainage by pushing the catheter to duodenum and thus - outflow of bile to the duodenum was secured even throughout the extrahepatic portion of the bile duct. Ten days later, after these initial drainage procedures a selfexpendible metallic stent has been inserted into the extrahepatic bile duct and sufficient drainage to duodenum has been reached.

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

  11. Malignant biliary obstruction treated with metallic stents

    International Nuclear Information System (INIS)

    Purpose: The outcome of 33 patients with malignant biliary obstruction treated with metallic stents is presented. Materials and methods: Thirty-eight biliary metallic stents were placed in 33 patients with malignant biliary obstruction. They were 52-71 years old (mean = 61.7); 23 were male and 10 were female. The biliary obstruction was caused by biliary carcinoma (n = 16), pancreatic carcinoma (n = 2), hepatoma (n = 2), metastasis in liver (n = 3) and lymph node metastasis (n = 10). Six types and 38 metallic stents were used. After stentering, 3 cases were treated with intrastent brachytherapy, 7 cases treated with external radiotherapy and 2 patients treated with interventional radiology. Patients were followed for 6-28 months, mean 11 months. Results: Stent placement was successful in all 33 cases. The same time, 4 patients were treated with plastic tube for external drainage only. The successful rate was 90%. Twenty-nine patients were placed in one time, 4 cases began with plastic tube which was replaced with metallic stents after 1-2 weeks. Nine had metallic stents and plastic tube, because of complicated obstruction. The external drainage catheters were removed after 15-200 days. Three patients had stents crossing the ampulla. In 28 cases (84.85%), jaundice was reduced satisfactorily while in 5 cases with complicated biliary obstruction, the result was unsatisfactory. The median survival was 7 months. After stentering, 12 cases were treated with locat chemotherapy, brachytherapy or radiotherapy. The median survival period was 10 months. Conclusion: The metallic stent provides good palliative drainage and is well tolerated by patients. It improves the survival rate when combined with radiotherapy, brachytherapy and chemotherapy in patients with malignant biliary obstruction

    AIM: To evaluate the serum concentration of antimitochondrial antibodies (AMAs) as a prognostic indicator of progressive primary biliary cirrhosis (pPBC).METHODS: Serum concentrations of AMA subtypes (anti-M2, anti-M4, and anti-M9), biochemical indices of liver function and Mayo risk factor (MRF) were determined in 30 women with diagnosed primary biliary cirrhosis (PBC) selected among 348 females with elevated alkaline phosphatase but without signs of hepatic decompensation.They were followed up for 5 years for possible development of hepatic decompensation.RESULTS: Anti-M2 concentration was significantly correlated with bilirubin and albumin levels as well as MRF, whereas anti-M4 was significantly correlated with albumin level, prothrombin time and MRF. During the 5-year follow-up, progressive PBC (pPBC) was diagnosed in 3 among 23 patients available for evaluation. These 3patients were positive for both anti-M2 and anti-M4.Anti-M2 serum concentration exceeded 1 300 RU/mL in patients with pPBC and only in 1 among 20 non-progressive PBC persons (5%). Anti-M4 serum concentration exceeded 400 RU/mL in 2 of the progressive patients and none in the non-progressive group. In contrast, anti-M9 serum concentration was below 100 RU/mL in all patients with pPBC, and higher than 100 RU/mL in 11 women (55%)among the non-progressive group.CONCLUSION: Females with elevated alkaline phosphatase and high anti-M2 and anti-M4 concentrations are at a high risk for developing pPBC. Quantitative AMA detection should be considered as a method for early diagnosis of pPBC.

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

This method was used to evaluate 31 patients with suspected biliary obstruction over a one-year period and the findings were compared with those of direct cholangiography and/or surgery. Biliary opacification was sufficient to allow three-dimensional reconstructions in 90,3% of cases. Sensitivity was 81% for the diagnosis of choledochoolithiasis and 100% for ascariasis, choledochal cysts and anatomic variants of the biliary tree. Our results indicate that HCTC is a valuable alternative as a diagnostic method prior to direct cholangiography. Direct cholangiography should be reserved for those patients who require it as part of a therapeutic procedure

    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.

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

    Abstract The significance of hepatobiliary scintigraphy (HBS) for hepatic graft function assessment was established mostly on retrospective studies and was not widely recognized due to the lack of quantitative data and variation in accuracy. This prospective study was performed to investigate the effectiveness of quantitative HBS for assessing hepatocyte dysfunction and biliary complication in liver transplant recipients. In 57 recipients who had undergone orthotopic liver transplantation, a total of 67 dynamic 99mTc-EHIDA scans were performed and quantitative parameters including the hepatocyte extraction fraction (HEF), time to maximum hepatic radioactivity (Tmax), and time for peak activity to decrease by 50% (T1/2) were calculated. The scintigraphic results based on the 3 parameters were compared against the final diagnosis. A ROC curve analysis was carried out to identify the cutoff value of Tmax for diagnosis of biliary stricture. Correlation between the parameters of postoperative HBS and conventional biochemical liver function indices were also analyzed. Quantitative 99mTc-EHIDA HBS had an overall sensitivity of 94.12% (16/17), specificity of 93.33% (42/45), and diagnostic accuracy of 93.55% (58/62) for detecting hepatocyte dysfunction and biliary complication in liver transplant recipients. The recommended cutoff value of Tmax for diagnosis of post-transplant biliary stricture was set at 15.75 min with a sensitivity of 100.0% and a specificity of 94.0%. The scintigraphic parameters (HEF, Tmax) were statistically significantly associated with the conventional liver function parameters. Quantitative 99mTc-EHIDA HBS offers a noninvasive imaging modality with high sensitivity and specificity to diagnose hepatocyte dysfunction as well as distinguish between patients with or without biliary stricture following liver transplantation. Furthermore, HEF and Tmax values obtained from dynamic HBS show good correlation with conventional liver function parameters

    Full Text Available Gallstones are the commonest cause of acute pancreatitis (AP, a potentially life-threatening condition, worldwide. The pathogenesis of acute pancreatitis has not been fully understood. Laboratory and radiological investigations are critical for diagnosis as well prognosis prediction. Scoring systems based on radiological findings and serologic inflammatory markers have been proposed as better predictors of disease severity. Early endoscopic retrograde cholangiopancreatography (ERCP is beneficial in a group of patients with gallstone pancreatitis. Laparoscopic cholecystectomy with preoperative endoscopic common bile duct clearance is recommended as a treatment of choice for acute biliary pancreatitis. The timing of cholecystectomy, following ERCP, for biliary pancreatitis can vary markedly depending on the severity of pancreatitis

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

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

    International Nuclear Information System (INIS)

    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)

    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.

    2014-02-01

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

  10. ETIOLOGY, PATHOGENESIS AND MORPHOLOGY OF BILIARY ATRESIA

    Directory of Open Access Journals (Sweden)

    O. E. Iryshkin

    2012-01-01

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

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

    Haim Pinkas; Patrick G. Brady

    2008-01-01

    BACKGROUND: Endoscopic retrograde cholangiopan-creatography (ERCP) with placement of a biliary stent or nasobiliary (NB) drain is the procedure of choice for treatment of post-cholecystectomy bile duct leaks. The aim of this study was to compare the effect of NB drainage versus internal biliary stenting on rates of leak closure, time elapsed until drain or stent removal, length of hospital stay and number of required endoscopic procedures. METHODS: Charts were reviewed on 20 patients who underwent laparoscopic cholecystectomy complicated by Luschka or cystic duct leak. Ten patients were treated with NB drains connected to low intermittent suction and repeat NB cholangiograms were performed until leak closure was observed. Ten patients were treated with internal biliary stents. Biliary sphincterotomies were performed for stone extraction or a presumed papillary stenosis. Large bilomas were drained percutaneously prior to stenting. RESULTS: In all 20 patients, a cholangiogram and successful placement of a NB drain or internal stent was achieved. Four patients (20%) were found to have bile duct stones, which were extracted following a sphincterotomy. Sixteen patients required percutaneous drains to evacuate large bilomas prior to biliary instrumentation. Fifteen cystic duct leaks and 5 Luschka duct leaks were reviewed. There were no complications related to ERCP. Closure of the leak was documented within 2 to 11 days (mean 4.7±0.9 days) in patients receiving a NB drain. The drains were removed non-endoscopically following leak closure. The internal stent group required stenting for 14 to 53 days (mean 29.1±4.4 days). The stent was then removed endoscopically after documentation of leak closure. Bile leaks following laparoscopic cholecystectomy closed rapidly after NB drainage and did not require repeat endoscopy for removal of the NB drain, resulting in fewer ERCPs required for treatment of biliary leaks. Internal biliary stents were in place longer owing

    Objective: To evaluate the therapeutic efficacy of linear 125I seeds strand implantation combined with biliary stenting in treating malignant biliary obstruction. Methods: Linear 125I seeds strand implantation combined with biliary stenting was carried out in 28 patients with malignant biliary obstruction. The technical success rate, the clinical efficacy, the postoperative complications and the survival rate were analyzed. Results: Both biliary stenting and 125I seeds strand implantation were successfully accomplished in all patients. No serious complications occurred. After the procedure the biliary obstruction symptoms were markedly improved and the bilirubin level was significantly reduced (P125I seeds strand implantation together with biliary stenting is safe and effective although its long-term efficacy needs to be further studied.

    A 68-year-old man underwent cholecystectomy and choledochoduodenostomy for biliary obstruction and nephrectomy for a renal tumor. Based on clinical and histopathologic findings, autoimmune pancreatitis (AIP) was diagnosed. The renal tumor was diagnosed as a renal cell cancer. Steroid therapy was started and thereafter pancreatic inflammation improved. Five years after surgery, the patient was readmitted because of pyrexia in a preshock state. A Klebsiella pneumoniae liver abscess complicated by sepsis was diagnosed. The patient recovered with percutaneous abscess drainage and administration of intravenous antibiotics. Liver abscess recurred 1 mo later but was successfully treated with antibiotics. There has been little information on long-term outcomes of patients with AIP treated with surgery. To our knowledge, this is the second case of liver abscess after surgical treatment of AIP.

    A 46-year-old woman was diagnosed with palmoplantar pustulosis (PPP) at the Department of Dermatology,Fukushima Medical University Hospital in 2000, and was treated with ointment. However, because liver dysfunction developed in 2003, she was referred to our department, where primary biliary cirrhosis (PBC)was also diagnosed on the basis of clinical findings.One year later, at the age of 49, she developed manifestations of Behcet's disease (BD), including erythema nodosum in the lower extremities. Because she had a history of uveitis, recurrent oral ulceration was present, and the HLA typing was positive for B51, BD was additionally diagnosed. Liver function normalized within three months of the start of treatment with ursodesoxycholic acid (UDCA). This is the first case of PBC associated with BD and PPP.

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

    One hundred patients with suspected biliary tract disease underwent gray scale cholecystosonography (GSCS) and had diagnostic confirmation by oral cholecystogram (OCG) and/or operation. Ultrasonography demonstrated the gallbladder in 94 of the 100 patients; 2 patients had had previous cholecystectomy and 3 of the 4 remaining patients had documented stones with no confirmation of a nonvisualizing OCG in the other patient. Among the 88 patients with OCG, GSCS findings correlated in 91 per cent (2 per cent false-positive; 7 per cent false-negative). Among the 43 operative patients, GSCS was proven correct in 91 per cent (no false positive; 9 per cent false-negative). Of 12 patients with jaundice GSCS correlated with operative findings in 75 per cent (no false-positive; 25 per cent false-negative). Diagnostic errors occurred in patients with very small biliary calculi, particularly when a single stone was impacted in the cystic duct. Failure to identify the gallbladder with ultrasound signifies probable cholelithiasis in the patient without previous cholecystectomy. On the basis of this experience, we conclude that (1) GSCS is most useful when jaundice or acute illness precludes conventional studies; (2) GSCS provides an inexpensive, quick, accurate means of diagnosing cholelithiasis with a very high specificity (97 per cent) and moderate sensitivity (88 per cent); and (3) GSCS is the optimal diagnostic procedure for evaluating the biliary tract in the acutely ill, jaundiced, vomiting, allergic, and/or pregnant patient.

    AIM: To determine the role of circulating tumor cells (CTCs) in prediction of the overall survival of patients with advanced malignant biliary tract obstruction. METHODS: We investigated the prognostic value of CTCs by examining two markers, cytokeratin (CK) 19 and human telomerase reverse transcriptase (hTERT) mRNA, in 40 patients diagnosed with advanced malignant biliary tract diseases. Quantitative real-time reverse transcription polymerase chain reaction was used to detect CK19 and hTERT mRNA in the peripheral blood of these patients. Overall survival was analyzed using the Kaplan-Meier method and Cox regression modeling. RESULTS: Positive CK19 and hTERT mRNA expression was detected in 45% and 60%, respectively, of the 40 patients. Univariable analysis indicated that positive CK19 mRNA expression was significantly associated with worse overall survival (P = 0.009). Multivariable analysis determined that positive CK19 mRNA expression, patient's age and serum bilirubin were each independently associated with overall survival. CONCLUSION: CK19 mRNA expression levels in peripheral blood appear to provide a valuable marker to predict the overall survival of patients with advanced malignant biliary tract obstruction.

    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.

  3. Endoscopic management of benign biliary strictures.

    2015-01-01

    Benign biliary strictures are a common indication for endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic management has evolved over the last 2 decades as the current standard of care. The most common etiologies of strictures encountered are following surgery and those related to chronic pancreatitis. High-quality cross-sectional imaging provides a road map for endoscopic management. Currently, sequential placement of multiple plastic biliary stents represents the preferred approach. There is an increasing role for the treatment of these strictures using covered metal stents, but due to conflicting reports of efficacies as well as cost and complications, this approach should only be entertained following careful consideration. Optimal management of strictures is best achieved using a team approach with the surgeon and interventional radiologist playing an important role.

    New technological developments in endoscopic retrograde cholangiopancreatography and endoscopic ultrasound, both for diagnosis and treatment of biliary and pancreatic diseases, have opened up new scenarios in the recent years. For instance, removal of large bile duct stones with endoscopic sphincterotomy followed by large balloon dilation has been proven to be a safe and effective technique. Also cholangioscopy evolved in terms of better imaging, tissue acquisition and stones management. Self-expandable metal stents are used mostly for malignant diseases, but their role in benign diseases has also been deeply investigated in the last years. The rapid evolution in the field of radiofrequency brought new devices for safer ablation and palliation of biliary tumours. Self-expandable metal stents are also used for ultrasound-guided drainage of walled off pancreatic necrosis and for choledocoduodenostomy and cholecystogastrostomy. PMID:27362720

  6. Hemobilia after percutaneous transhepatic biliary drainage

    International Nuclear Information System (INIS)

    Objective: To retrospectively analyze the occurance and management for patients with hemobilia after percutaneous transhepatic biliary drainage (PTBD). Methods: Consecutive 139 patients with inoperable obstructive jaundice were treated by PTBD. After taking percutaneous transhepatic cholangiography, procedure of puncturing the dilated biliary duct with metallic stent or plastic catheter placement was undertaken. Follow up was carded out with clinical, radiographic and laboratory evaluation. Procedure-and device-related complications were also recorded. Results: All patients went though PTBD successfully with total serum bilirnbin reducing from 360 μmol/l to 158.2 μmol/l, postoperatively. 43 cases received hemostatic. Transient hemobilia occurred in 11 cases, and severe hemobilia in other 5 cases requiring further management. Other 4 cases needed arterial embolization with another one failure. Conclusion: Hemobilia is a complication after PTBD, which can be promptly controlled with improving skillful maneuver. (authors)

  7. Recent Advances of Biliary Stent Management

    International Nuclear Information System (INIS)

    Recent progress in chemotherapy has prolonged the survival of patients with malignant biliary strictures, leading to increased rates of stent occlusion. Even we employed metallic stents which contributed to higher rates and longer durations of patency, and occlusion of covered metallic stents now occurs in about half of all patients during their survival. We investigated the complication and patency rate for the removal of covered metallic stents, and found that the durations were similar for initial stent placement and re-intervention. In order to preserve patient quality of life, we currently recommend the use of covered metallic stents for patients with malignant biliary obstruction because of their removability and longest patency duration, even though uncovered metallic stents have similar patency durations.

    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

    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.

    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.

  1. Excretion of biliary compounds during intrauterine life

    In adults, the hepatobiliary system, together with the kidney, constitute the main routes for the elimination of several endogenous and xenobiotic compounds into bile and urine, respectively. However, during intrauterine life the biliary route of excretion for cholephilic compounds, such as bile acids and biliary pigments, is very poor. Although very early in pregnancy the fetal liver produces bile acids, bilirubin and biliverdin, these compounds cannot be efficiently eliminated by the fetal hepatobiliary system, owing to the immaturity of the excretory machinery in the fetal liver. Therefore, the potentially harmful accumulation of cholephilic compounds in the fetus is prevented by their elimination across the placenta. Owing to the presence of detoxifying enzymes and specific transport systems at different locations of the placental barrier, such as the endothelial cells of chorionic vessels and trophoblast cells, this organ plays an important role in the hepatobiliary-like function during intrauterine life. The relevance of this excretory function in normal fetal physiology is evident in situations where high concentrations of biliary compounds are accumulated in the mother. This may result in oxidative stress and apoptosis, mainly in the placenta and fetal liver, which might affect normal fetal development and challenge the fate of the pregnancy. The present article reviews current knowledge of the mechanisms underlying the hepatobiliary function of the fetal-placental unit and the repercussions of several pathological conditions on this tandem.

    Endoscopic ultrasound(EUS) is used for diagnosis and evaluation of many diseases of the gastrointestinal (GI) tract. In the past, it was used to guide a cholangio-graphy, but nowadays it emerges as a powerful thera-peutic tool in biliary drainage. The aims of this review are: outline the rationale for endoscopic ultrasound-guided biliary drainage(EGBD); detail the procedural technique; evaluate the clinical outcomes and limitations of the method; and provide recommendations for the practicing clinician. In cases of failed endoscopic retro-grade cholangiopancreatography(ERCP), patients are usually referred for either percutaneous transhepatic biliary drainage(PTBD) or surgical bypass. Both these procedures have high rates of undesirable complications. EGBD is an attractive alternative to PTBD or surgery when ERCP fails. EGBD can be performed at two locations: transhepatic or extrahepatic, and the stent can be inserted in an antegrade or retrograde fashion. The drainage route can be transluminal, duodenal or trans-papillary, which, again, can be antegrade or retrograde [rendezvous(EUS-RV)]. Complications of all techniques combined include pneumoperitoneum, bleeding, bile leak/peritonitis and cholangitis. We recommend EGBD when bile duct access is not possible because of failed cannulation, altered upper GI tract anatomy, gastric outlet obstruction, a distorted ampulla or a periampullary diverticulum, as a minimally invasive alternative to surgery or radiology.

    We report two cases of bilothorax that occurred as a complication of percutaneous transhepatic biliary drainage. In an 86-year-old woman who had undergone percutaneous transhepatic biliary drainage for obstructive jaundice, bilothorax occurred after accidental removal of the tube. She recovered with chest drainage only. An 83-year-old man who had undergone percutaneous transhepatic biliary drainage for cholecystitis developed bilothorax with infection. He recovered with thoracoscopic curettage. Although bilothorax is a rare complication of percutaneous transhepatic biliary drainage, appropriate diagnosis and prompt treatment is important, especially when bilothorax is accompanied by infection.

    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. PMID:22566787

    Background Biliary injury after radiofrequency ablation can cause serious consequences including death. However, there are limited data regarding bile duct changes with or without complications associated with radiofrequency ablation of hepatic malignancies. This study aimed to assess the incidence, prognosis and risk factors of intrahepatic biliary injury associated with radiofrequency ablation.Methods Between June 2001 and January 2009, 638 patients with hepatic malignancies (405 with hepatocellular carcinoma, and 233 with liver metastasis) who had 955 treatment sessions were enrolled in this study. Imaging and laboratory data, the course of treatment, and patient outcomes were reviewed retrospectively. The risk factors of biliary injury and the impact on overall survival of patients were analyzed. The chi-square test, Fisher's exact test, Kaplan-Meier curves and stepwise Logistic regression model were used for statistical analysis where appropriate.Results Biliary injury was observed in 17 patients after 17 ablation sessions based on imaging findings. The overall incidence of biliary injury was 1.8% (17/955) with an average onset time of 12 weeks (2-36 weeks). Mild, moderate and severe complications of biliary injury were identified in 9, 6 and 2 cases, respectively. The median survival time after detection of biliary injury was 40 months. There seemed no notable difference in overall survival between patients with and those without biliary injuries. By multivariate analysis, vessel infiltration (P=0.034) and treatment session ≥4 times (P=0.025) were independent risk factors for biliary injury of hepatocellular carcinoma; while tumor located centrally was the only independent risk factor in the metastasis group (P=0.043).Conclusions The incidence of biliary injury was not frequent (1.8%). Through appropriate treatment, intrahepatic bile duct injuries seemed not affect the patients' long-term survival. Additionally, risk factors may be helpful for selecting

    BACKGROUND:The process of microcrystallization, its sequel and the assessment of nucleation time is ignored. This systematic review aimed to highlight the importance of biliary microlithiasis, sludge, and crystals, and their association with gallstones, unexplained biliary pain, idiopathic pancreatitis, and sphincter of Oddi dysfunction. DATA SOURCES:Three reviewers performed a literature search of the PubMed database. Key words used were"biliary microlithiasis","biliary sludge","bile crystals","cholesterol crystallisation","bile microscopy","microcrystal formation of bile", "cholesterol monohydrate crystals", "nucleation time of cholesterol", "gallstone formation", "sphincter of Oddi dysfunction"and"idiopathic pancreatitis". Additional articles were sourced from references within the studies from the PubMed search. RESULTS:We found that biliary microcrystals account for almost all patients with gallstone disease, 7% to 79% with idiopathic pancreatitis, 83% with unexplained biliary pain, and 25%to 60%with altered biliary and pancreatic sphincter function. Overall, the detection of biliary microcrystals in gallstone disease has a sensitivity ranging from 55%to 87%and a speciifcity of 100%. In idiopathic pancreatitis, the presence of microcrystals ranges from 47%to 90%. A nucleation time less than 10 days in hepatic bile or ultra-ifltered gallbladder bile has a speciifcity of 100%for cholesterol gallstone disease. CONCLUSIONS:Biliary crystals are associated with gallstone disease, idiopathic pancreatitis, sphincter of Oddi dysfunction, unexplained biliary pain, and post-cholecystectomy biliary pain. Pathways of cholesterol super-saturation, crystallisation, and gallstone formation have been described with scientiifc support. Bile microscopy is a useful method to detect microcrystals and the assessment of nucleation time is a good method of predicting the risk of cholesterol crystallisation.

    AIM To evaluate the role of intraoperative cholangiogram (IOC) in preventing biliary duct injury duringlaparoscopic cholecystectomy.METHODS Injury location, mechanism, time of detection, treatment outcome, and whether anintraoperative cholangiogram was performed were evaluated in 31 cases of bile duct injuries.RESULTS Cholangiograms were done in 22 cases, but they were misinterpreted in 3 of them. In 12 of 19misidentified cases, the cholangiogram was interpreted correctly, and the injury detected intraoperatively.Primary laparoscopic repair or open repair and T-tube drainage solved the problem. No long-termcomplications occurred. However, in 3 of the 19 cases the cholangiogram was misinterpreted and in 4 of the19 cases no cholangiogram was performed. Three of the seven patients required a cholangioentericanastomosis. In 2 cases the diagnosis was delayed and one of these required a two-stage procedure. Morbiditywas increased. Three cases of clim impingement of the common duct had delayed diagnoses, and two of themhad injuries. Thermal injury developed in 4 cases who had cholangiograms.CONCLUSION Routine IOC plays no role in inducing, preventing, detecting, or minimizing any of theinjuries due to clips, lacerations, or electrocautery, IOC does not prevent injuries due to ductmisidentification either. Careful interpretation of IOC would prevent injuries and avoid an open operation.

    The first-choice therapy for biliary atresia (BA) is Kasai hepatoportoenterostomy, which has been shown to greatly improve outcome. Various long-term complications, however, such as portal hypertension and hepatopulmonary syndrome (HPS), can occur in patients with native liver. A rare case of brain abscess in an 11-year-old girl with HPS associated with BA is reported. The patient underwent hepatoportoenterostomy for BA at 53 days of age, with resolution of hyperbilirubinemia. At 10 years of age, she was diagnosed with severe HPS with right-to-left shunting, and preparations for liver transplantation proceeded. Three months after the diagnosis, she had a right parietal brain abscess. Given that the brain abscess enlarged in size, surgical drainage of the brain abscess was performed. The postoperative course was uneventful, but a slight left hemiplegia remained at discharge. The presumed mechanism of abscess formation in HPS may be right-to-left bacterial transit through intrapulmonary vascular dilatations and/or arteriovenous fistulae. PMID:26711920

    Full Text Available Background/Purpose: This study aims to analyze the incidence and type of various associated anomalies among infants with extrahepatic biliary atresia (EHBA, compare their frequency with those quoted in the existing literature and assess their role in the overall management. Materials and Methods: A retrospective study was performed on 137 infants who underwent the Kasai procedure for EHBA during the past 12 years. The medical records were reviewed for the incidence and type of associated anomalies in addition to the details of the management of the EHBA. Results: Of the137 infants, 40 (29.2% were diagnosed as having 58 anomalies. The majority of patients had presented in the 3 rd month of life; mean age was 81 ± 33 days (range = 20-150 days. There were 32 males and 8 females; boys with EHBA had a higher incidence of associated anomalies. Of these 40 patients, 22 (37.9% had vascular anomalies, 13 patients (22.4% had hernias (umbilical-10, inguinal-3, 7 patients (12.1% had intestinal malrotation, 4 patients (6.8% had choledochal cyst, 1 patient (1.7% had Meckel′s diverticulum, 3 patients (5% had undergone prior treatment for jejunoileal atresias (jejunal-2, ileal-1, 2 patients (3.4% had undergone prior treatment for esophageal atresia and tracheoesophageal fistula, 2 patients (3.4% had spleniculi, and 2 patients (3.4% were diagnosed as having situs inversus. Conclusions: The most common associated anomalies in our study were related to the vascular variation at the porta hepatis and the digestive system. The existence of anomalies in distantly developing anatomic regions in patients with EHBA supports the possibility of a "generalized" insult during embryogenesis rather than a "localized" defect. In addition, male infants were observed to have significantly more associated anomalies as compared with the female infants in contrast to earlier reports.

The survival and stent patency rate were calculated by Kaplan-Meier survival analysis.RESULTS: Twenty-two patients underwent chemotherapy (11 cases of hepatic carcinoma, 7 cases of pancreatic carcinoma, 4 cases of metastatic lymphadenopathy), and 14 patients received radiotherapy (10 cases of cholangiocarcinoma, 4 cases of pancreatic carcinoma), and 13patients Accepted: brachytherapy (7 cases of cholangiocarcinoma, 3 cases of pancreatic carcinoma, 4 cases of metastatic lymphadenopathy). The survival rate of the local tumor treatment group at 1, 3, 6, and 12 months was 97.96%, 95.92%, 89.80%, and 32.59% respectively,longer than that of the non treatment group. The patency rate at 1, 3, 6, and 12 months was 97.96%, 93.86%,80.93%, and 56.52% respectively. The difference of patency rate was not significant between treatment group and non treatment group.CONCLUSION: Our results suggest that local tumor therapy could prolong the survival time of patients with malignant biliary obstruction, and may improve stent patency.

    The human ovarian mucinous cystadenocarcinoma (hOMC) cells were co-cultured with antisense oligodeoxynucleotide (antisense ODN), nonsense ODN, and follicle-stimulating hormone (FSH) at different concentrations for the purpose of observing the effects of antisense ODN to FSH receptor (FSHR) on the proliferation and apoptosis of cultured hOMC cells in vitro. The inhibitory rates of growth were measured by using MTT method on the 2nd, 4th, 6th, 8th and 10th days after the interference of antisense ODN, nonsense ODN, and FSH, respectively. The apoptotic rates and the cell cycles were determined by means of flow cytometry, the apoptosis indexes were detected by using TUNEL, and the expression of caspase-3 was measured by using SP immunohistochemistry. Compared with that in the control group, the proliferative activity of hOMC cells was increased obviously in FSH groups (P<0.05 or P<0.01), decreased distinctly in antisense ODN groups (P<0.05 or P<0.01), and unchanged in nonsense ODN groups, respectively. Meanwhile, antisense ODN could significantly antagonize the FSH-promoted cell proliferative activity (P<0.01). Compared with those in the control group, the apoptotic rates and the expression of caspase-3 were dramatically increased in the mid- and high-dose antisense ODN groups (P<0.05 or P<0.01), while the number of cells in G1/G0 phase was significantly decreased and that in S phase distinctly increased (P<0.01). There was no change in nonsense ODN groups (P>0.05). It was suggested that FSH may improve the development of hOMC cells. However, antisense ODN could inhibit proliferative activity and the FSH-promoted proliferative activity in hOMC cells, at the same time, antisense ODN could inhibit hOMC cell growth by inducing apoptosis.

    We encapsulate indocyanine green (ICG) in poly[(D,L-lactide-co-glycolide)-co-PEG] diblock (PLGA-PEG) microballoons for real-time fluorescence and hyperspectral imaging of biliary anatomy. ICG-loaded microballoons show superior fluorescence characteristics and slower degradation in comparison with pure ICG. The use of ICG-loaded microballoons in biliary imaging is demonstrated in both biliary-simulating phantoms and an ex vivo tissue model. The biliary-simulating phantoms are prepared by embedding ICG-loaded microballoons in agar gel and imaged by a fluorescence imaging module in a Da Vinci surgical robot. The ex vivo model consists of liver, gallbladder, common bile duct, and part of the duodenum freshly dissected from a domestic swine. After ICG-loaded microballoons are injected into the gallbladder, the biliary structure is imaged by both hyperspectral and fluorescence imaging modalities. Advanced spectral analysis and image processing algorithms are developed to classify the tissue types and identify the biliary anatomy. While fluorescence imaging provides dynamic information of movement and flow in the surgical region of interest, data from hyperspectral imaging allow for rapid identification of the bile duct and safe exclusion of any contaminant fluorescence from tissue not part of the biliary anatomy. Our experiments demonstrate the technical feasibility of using ICG-loaded microballoons for biliary imaging in cholecystectomy.

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

  1. The role of sonography in imaging of the biliary tract.

    Science.gov (United States)

    Foley, W Dennis; Quiroz, Francisco A

    2007-06-01

    Sonography is the recommended initial imaging test in the evaluation of patients presenting with right upper quadrant pain or jaundice. Dependent upon clinical circumstances, the differential diagnosis includes choledocholithiasis, biliary stricture, or tumor. Sonography is very sensitive in detection of mechanical biliary obstruction and stone disease, although less sensitive for detection of obstructing tumors, including pancreatic carcinoma and cholangiocarcinoma. In patients with sonographically documented cholelithiasis and choledocholithiasis, laparoscopic cholecystectomy with operative clearance of the biliary stone disease is usually performed. In patients with clinically suspected biliary stone disease, without initial sonographic documentation of choledocholithiasis, endoscopic ultrasound or magnetic resonance cholangiopancreatography is the next logical imaging step. Endoscopic ultrasound documentation of choledocholithiasis in a postcholecystectomy patient should lead to retrograde cholangiography, sphincterotomy, and clearance of the ductal calculi by endoscopic catheter techniques. In patients with clinical and sonographic findings suggestive of malignant biliary obstruction, a multipass contrast-enhanced computed tomography (CT) examination to detect and stage possible pancreatic carcinoma, cholangiocarcinoma, or periductal neoplasm is usually recommended. Assessment of tumor resectability and staging can be performed by CT or a combination of CT and endoscopic ultrasound, the latter often combined with fine needle aspiration biopsy of suspected periductal tumor. In patients whose CT scan suggests hepatic hilar or central intrahepatic biliary tumor, percutaneous cholangiography and transhepatic biliary stent placement is usually followed by brushing or fluoroscopically directed fine needle aspiration biopsy for tissue diagnosis. Sonography is the imaging procedure of choice for biliary tract intervention, including cholecystostomy, guidance for

    Full Text Available Background. Accurate diagnosis and clinical management of indeterminate biliary strictures are often a challenge. Tissue confirmation modalities during Endoscopic Retrograde Cholangiopancreatography (ERCP suffer from low sensitivity and poor diagnostic accuracy. Probe-based confocal laser endomicroscopy (pCLE has been shown to be sensitive for malignant strictures characterization (98% but lacks specificity (67% due to inflammatory conditions inducing false positives. Methods. Six pCLE experts validated the Paris Classification, designed for diagnosing inflammatory biliary strictures, using a set of 40 pCLE sequences obtained during the prospective registry (19 inflammatory, 6 benign, and 15 malignant. The 4 criteria used included (1 multiple thin white bands, (2 dark granular pattern with scales, (3 increased space between scales, and (4 thickened reticular structures. Interobserver agreement was further calculated on a separate set of 18 pCLE sequences. Results. Overall accuracy was 82.5% (n=40 retrospectively diagnosed versus 81% (n=89 prospectively collected for the registry, resulting in a sensitivity of 81.2% (versus 98% for the prospective study and a specificity of 83.3% (versus 67% for the prospective study. The corresponding interobserver agreement for 18 pCLE clips was fair (k=0.37. Conclusion. Specificity of pCLE using the Paris Classification for the characterization of indeterminate bile duct stricture was increased, without impacting the overall accuracy.

    AIM: To investigate the role of preoperative biliary drainage (PBD) in the outcome of classical pancreaticodu odenectomy.METHODS: A 10-year retrospective data analysis was performed on patients (n = 48) undergoing pancreaticoduodenectomy from March 1994 to March 2004 in department of surgery at SMS medical college, Jaipur, India. Demographic variables, details of preoperative stenting, operative procedure and post operative complications were noted.RESULTS: Preoperative biliary drainage was performed in 21 patients (43.5%). The incidence of septic complications was significantly higher in patients with biliary stent placement (P < 0.05, 0 vs 4). This group of patients also had a significantly higher minor biliary leak rate. Mortality and hospital stay in each group was comparable.CONCLUSION: Within this study population the use of PBD by endoscopic stenting was associated with a high incidence of infective complications. These findings do not support the routine use of biliary stenting in patients prior to pancreatico-duodenectomy.

    AIM:To demonstrate the imaging findings of biliopancreatic and pancreatico-biliary reflux in patients with anomalous union of the pancreatico-biliary duct (AUPBD)on gadoxetic acid-enhanced functional magnetic resonance cholangiography (fMRC).METHODS:This study included six consecutive patients (two men and four women; mean age 47.5 years) with AUPBD.All subjects underwent endoscopic retrograde cholangiopancreatography (ERCP); one subject also underwent bile sampling of the common bile duct (CBD) to measure the amylase level because his gadoxetic acidenhanced fMRC images showed evidence of pancreatico-biliary reflux of pancreatic secretions.Of the five patients with choledochal cysts,four underwent pyloruspreserving pancreaticoduodenectomy.RESULTS:The five cases of choledochal cysts were classified as Todani classification I.In three of the six patients with AUPBD,injected contrast media reached the distal CBD and pancreatic duct on delay images,suggesting biliopancreatic reflux.In two of these six patients,a band-like filling defect was noted in the CBD on pre-fatty meal images,which decreased in size on delayed post-fatty meal images,suggesting pancreatico-biliary reflux of pancreatic secretions,and the bile sampled from the CBD in one patient had an amylase level of 113 000 IU/L.In one of the six patients with AUPBD,contrast media did not reach the distal CBD due to multiple CBD stones.CONCLUSION:Gadoxetic acid-enhanced fMRC successfully demonstrated biliopancreatic reflux of bile and pancreatico-biliary reflux of pancreatic secretions in patients with AUPBD with and without choledochal cysts.

  6. Percutaneous cholangioscopy in obstructed biliary metal stents

    International Nuclear Information System (INIS)

    Purpose. To reevaluate the reasons for the occlusion of self-expanding biliary metal stents, on the basis of cholangioscopic findings. Methods. Percutaneous transhepatic cholangioscopy (PTCS) was performed in 15 patients with obstructed biliary Wallstents. The reason for stent insertion was a malignant obstruction in 14 patients; 1 had a benign biliary stricture. Conventional noncovered stents had been inserted in 12 patients; in 3 cases a polyurethane-covered prototype Wallstent had been used. Stent occlusions occurred after 1-55 months. PTCS was performed with a 2.3-mm endoscope through an 11 Fr sheath. Biopsies were taken via the working channel of the endoscope. Results. In all patients with noncovered stents the inner surface of the stent was highly irregular with seaweed-like protrusions (biopsy-proven granulation tissue). Stent incorporation varied from absent (n=1) to subtotal (n=8), but was always incomplete, no matter how long the stent had been in place. Tumor ingrowth was histologically proven in 2 patients. One patient had a large occluding concrement at the proximal end of the stent. In patients with covered stents, the inner surface appeared more regular; however, viable granulation tissue was found inside two stents and tumor ingrowth in one of them. Conclusion. PTCS showed that incorporation of the stent is virtually always incomplete. The factors contributing most to stent occlusion are the buildup of granulation tissue, bile sludge, and tumor overgrowth. Stone formation and tumor ingrowth can also be important, although less common causes of occlusion. A polyurethane stent covering could not prevent tumor ingrowth in one patient and the buildup of viable granulation tissue inside the stent in two further patients; mean stent patency in the three patients with such a stent was 3 months

    The amylase creatinine clearance ratio (ACCR) is considered to be a more sensitive index of acute pancreatitis than the serum amylase level. Serial ACCR estimations were undertaken in 25 patients undergoing an elective cholecystectomy. Using accepted criteria, 28% of these patients developed, in the postoperative period, biochemical evidence of pancreatic gland damage, although the serum amylase level remained normal. This raised ACCR was particularly noted in patients who had undergone an exploration of the common bile duct. The ACCR would appear to be a more sensitive index of pancreatic gland disruption secondary to biliary surgery than the serum amylase level.

    BACKGROUND: Ischemia-related biliary tract complications remain high after orthotopic liver transplantation. Severe ischemic biliary complications often involve the hepatic duct bifurcation and left hepatic duct, resulting finally in obstructive jaundice. Prevention and management of such complications remain a challenge for transplant surgeons. METHODS: All 160 patients were followed up for at least 180 days after transplantation. One-way analysis of variance (ANOVA) and comparative univariate analysis were made using 3 groups (no complications; mild complications;severe complications), to analyze risk factors associated with biliary complications. Multiple logistic regression and linear regression analysis were used to analyze independent risk factors for severe ischemic biliary complications, after excluding other confounding factors. RESULTS: By ANOVA and comparative univariate analysis, the risk factors associated with biliary complications were preoperative bilirubin level (P=0.007) and T-tube stenting of the anastomosis (P=0.016). Multiple logistic regression analysis showed that the use of T-tube and preoperative serum bilirubin were not independent risk factors for severe ischemic biliary complications after orthotopic liver transplantation. Chi-square analysis indicated that in the incidence of severe ischemic biliary lesions, bile duct second warm ischemic time longer than 60 minutes was a significant risk factor. Linear regression demonstrated a negative correlation between cold preservation time and warm ischemia time. CONCLUSIONS: Preoperative serum bilirubin level and the use of T-tube stenting of the anastomosis were independent risk factors for biliary complications after liver transplantation, but not for severe ischemic biliary complications. The second warm ischemia time of bile duct longer than 60 minutes and prolonged bile duct second warm ischemia time combined with cold preservation time were significant risk factors for severe

    Biliary endoscopic drainage using metallic self-expanded stents has become a well-established method for palliative treatment of malignant biliary obstruction. However, its occlusion, mainly by tumor overgrowth, is still the main complication without a standard treatment. We here describe a new method of treatment for biliary metallic stent occlusion, through the echo guided biliary drainage. We present a 68-year-old patient with metastatic pancreatic cancer previously treated for jaundice with ERCP and self-expandable metallic stent insertion. Four weeks later, the patient developed jaundice and symptoms of gastric outlet obstruction. A new ERCP confirmed obstruction of the second portion of the duodenum, due to diffuse tumor growth. EUS was performed, and the previous metal biliary stent was seen occluded at the distal portion in the common bile duct. A EUS-guided choledocododenostomy was performed and then, an overlapping self-expanding metal enteral stent was placed through the malignant obstruction. There were no early complications and the procedure was also clinically effective in relieving jaundice and gastric outlet obstruction symptoms. If ERCP fails in the management of occluded biliary metallic stents, EUS biliary drain can provide effective biliary decompression and should be considered an alternative to other endoscopic techniques.

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

  13. Elevated serum levels of a biliary glycoprotein (BGP I) in patients with liver or biliary tract disease

    International Nuclear Information System (INIS)

    Human hepatic bile contains a glycoprotein (Biliary glycoprotein I BGP I) which cross-reacts with the carcinoembryonic antigen (CEA). A radioimmunoassay for BGP I was developed. The interference of CEA or 'non-specific cross-reacting antigen' (NCA) was small. The serum levels of BGP I were determined in healthy subjects, in patients with hepato-biliary diseases and in patients with various infections or inflammatory disorders. Healthy individuals, including pregnant women, had a serum BGP I concentration of about 0.5 - 1 mg/l. Diseases of the liver or biliary tract (e.g. hepatitis A or B, cytomegalovirus Hepatitis, obstructive jaundice or primary biliary cirrhosis) were associated with elevated serum levels of BGP I, as opposed to infectious diseases not affecting the liver mostly showing values within the normal range. Raised levels of serum BGP I activity may reflect biliary obstruction as a results of interference with normal BGP I secretion in the bile. (author)

    Ostomies are placed in children for different indications than in the older population. Many ostomies of childhood are placed because of congenital or neonatal problems that require temporary or long-term diversion to stabilize the neonatal patient. Necrotizing enterocolitis, the most common reason for placement of neonatal colostomies and ileostomies, is increasing in frequency as more prematurely born infants survive. Recently, there has been an increase in treatment of various biliary hypoplasia syndromes with biliary cutaneous diversion. Children with biliary hypoplasia syndromes are a challenging group of patients who frequently can be helped by ostomies. This article reviews current information on biliary cutaneous diversion for the biliary hypoplasia syndromes and intestinal diversion for necrotizing enterocolitis.

    Endoscopic ultrasonography-guided biliary drainage (EUS-BD) has been developed as an alternative drainage technique in patients with obstructive jaundice where endoscopic retrograde cholangiopancreatography (ERCP) has failed. Between July 2008 and December 2009, 16 patients (9 men; median age 79 years) with biliopancreatic malignancy, who were candidates for alternative techniques of biliary decompression because ERCP had been unsuccessful, underwent EUS-BD with placement of a transmural or transpapillary partially covered nitinol self-expandable metal stent (SEMS). EUS-assisted cholangiography was successful in all patients, with definition of the relevant anatomy, but biliary drainage was successfully performed in only 12 (75 %) of the 16 patients (9 choledochoduodenostomies with SEMS placement and 3 biliary rendezvous procedures with papillary SEMS placement), with regression of the cholestasis. No major complications and no procedure-related deaths occurred. There was one case of pneumoperitoneum which was managed conservatively. The median follow-up was 170 days. During the follow-up, eight patients of the 12 patients in whom biliary draining was successful died; four are currently alive. None of the patients required endoscopic reintervention. This series demonstrated that EUS-BD with a partially covered SEMS has a high rate of clinical success and low complication rates, and could represent an alternative choice for biliary decompression.

  16. Cholangiocyte anion exchange and biliary bicarbonate excretion

    Primary canalicular bile undergoes a process of fluidization and alkalinization along the biliary tract that is influenced by several factors including hormones, innervation/neuropeptides, and biliary constituents. Theexcretion of bicarbonate at both the canaliculi and the bile ducts is an important contributor to the generation of the so-called bile-salt independent flow. Bicarbonate is secreted from hepatocytes and cholangiocytes through parallel mechanisms which involve chloride efflux through activation of Cl- channels, and further bicarbonate secretion via AE2/SLC4A2-mediated Cl-/HCO3-exchange. Glucagon and secretin are two relevant hormones which seem to act very similarly in their target cells (hepatocytes for the former and cholangiocytes for the latter). These hormones interact with their specific G protein-coupled receptors, causing increases in intracellular levels of cAMP and activation of cAMP-dependent Cl- and HCO3- secretory mechanisms. Both hepatocytes and cholangiocytes appear to have cAMP-responsive intracellular vesicles in which AE2/SLC4A2 colocalizes with cell specific Cl- channels (CFTR in cholangiocytes and not yet determined in hepatocytes) and aquaporins (AQP8 in hepatocytes and AQP1 in cholangiocytes). cAMP-induced coordinated trafficking of these vesicles to either canalicular or cholangiocyte lumenal membranes and further exocytosis results in increased osmotic forces and passive movement of water with net bicarbonate-rich hydrocholeresis.

  17. Endoscopic treatment of malignant biliary strictures.

    2015-01-01

    Endoscopic stenting is a widely accepted strategy for providing effective drainage in both extrahepatic and intrahepatic malignant strictures. In patients with extrahepatic malignancies, uncovered self-expanding metal stents (SEMS) provide excellent palliation. Hilar malignancies are probably best palliated by placement of uncovered SEMS although some disagreement exists among experts regarding the type and number of stents for optimal palliation. Preoperative biliary drainage (PBD) is commonly performed although a higher risk of complications and the lack of clear benefit raise questions about this practice. Certain groups of patients such as those with markedly elevated bilirubin levels, and in those in whom neoadjuvant therapy is planned, are good candidates for PBD. Considerable controversy exists regarding the optimal method as well as type of stent for PBD in patients with hilar malignancies. Novel endoscopic therapies, including photodynamic therapy and radiofrequency ablation, have emerged as potential adjuvant therapies in the management of malignant bile duct strictures but need further long-term evaluation to establish survival benefit. This review focuses on the current status of endoscopic therapies for malignant biliary obstructions.

    Malignant obstruction of the bile duct from cholangiocarcinoma, pancreatic adenocarcinoma, or other tumors is a common problem which may cause debilitating symptoms and increase the risk of subsequent surgery. The optimal treatment - including the decision whether to treat prior to resection - depends on the type of malignancy, as well as the stage of disease. Preoperative biliary drainage is generally discouraged due to the risk of infectious complications, though some situations may benefit. Patients who require neoadjuvant therapy will require decompression for the prolonged period until attempted surgical cure. For pancreatic cancer patients, self-expanding metallic stents are superior to plastic stents for achieving lasting decompression without stent occlusion. For cholangiocarcinoma patients, treatment with percutaneous methods or nasobiliary drainage may be superior to endoscopic stent placement, with less risk of infectious complications or failure. For patients of either malignancy who have advanced disease with palliative goals only, the choice of stent for endoscopic decompression depends on estimated survival, with plastic stents favored for survival of stent patency and patient survival for these patients by achieving local control of the obstructing tumor. Both photodynamic therapy and radiofrequency ablation may play a role in extending survival of patients with malignant biliary obstruction. PMID:27326319

    We investigated the efficacy of different biliary drainage methods for the treatment of unresectable cholangiocarcinomas. We performed a retrospective study of 28 patients with unresectable cholangiocarcinomas who underwent biliary drainage at our hospital between January 2008 and June 2014 to compare the incidence of post-drainage stent dysfunction (SD) and reintervention (RI) for SD according to primary drainage method, lesion site, and complication status (the presence or absence of cholangitis). The duration of stent patency was compared between the different stent types. No significant differences in the incidence of SD and RI were found according to primary drainage methods, lesion site, or the presence or absence of cholangitis. The mean durations of stent patency for plastic and metal stents were 2.7 months and 7.4 months, respectively, suggesting that metal stents should be selected when the estimated prognosis is ≥2 months. Furthermore, metal stent placement, rather than the additional placement of plastic stents, should be considered a feasible option in cases of SD. PMID:26805093

  20. Metallic stents in malignant biliary obstruction

    International Nuclear Information System (INIS)

    Purpose. Retrospective analysis of our results with metallic stent placement for malignant biliary strictures. We sought to determine parameters that influence stent patency. Methods. A total of 95 Wallstents were implanted in 65 patients (38 men, 27 women; mean age, 65.1 years) with malignant biliary obstruction. Serum bilirubin levels were assessed in 48 patients; the mean value prior to intervention was 15.0 mg/dl. Results. In 12 patients (21%) complications occurred as a result of percutaneous transhepatic drainage. Stent implantation was complicated in 13 patients, but was possible in all patients. A significant decrease in bilirubin level was seen in 83.3% of patients following stent implantation. Approximately 30% of patients developed recurrent jaundice after a mean 97.1 days. In 9 patients (15%) the recurrent jaundice was caused by stent occlusion due to tumor growth. The mean follow-up was 141.8 days, the mean survival 118.7 days. Patients with cholangiocarcinomas and gallbladder carcinomas had the best results. Worse results were seen in patients with pancreatic tumors and with lymph node metastases of colon and gastric cancers. Conclusions. The main predictive factors for occlusion rate and survival are the type of primary tumor, tumor stage, the decrease in bilirubin level, and the general condition of the patient

    Biliary atresia (BA) is a rare and severe inflammatory and obliterative cholangiopathy that affects both extra- and intrahepatic bile ducts. BA symptoms occur shortly after birth with jaundice, pale stools and dark urines. The prognosis of BA has dramatically changed in the last decades: before the Kasai operation most BA patients died, while nowadays with the sequential treatment with Kasai operation±liver transplantation BA patient survival is close to 90%. Early diagnosis is very important since the chances of success of the Kasai procedure decrease with time. The causes of BA remain actually unknown but several mechanisms including genetic and immune dysregulation may probably lead to the obliterative cholangiopathy. Current research focuses on the identification of blood or liver factors linked to the pathogenesis of BA that could become therapeutic targets and avoid the need for liver transplantation. No similar disease leading to total obstruction of the biliary tree exists in older children or adults. But understanding the physiopathology of BA may highlight the mechanisms of other destructive cholangiopathies, such as sclerosing cholangitis. PMID:26775892

    Context When ERCP fails in the setting of combined biliary and duodenal obstruction, EUS-guided biliary drainage has emerged as an alternate method of biliary decompression. Case report We present a case of a 40-year-old man with advanced pancreatic cancer and a pre-existing duodenal wall stent who subsequently develops jaundice due to biliary obstruction. An ERCP was technically unsuccessful as the papilla was inaccessible despite probing within the duodenal stent. Transduodenal biliary drai...

    Biliary duct injuries are frequently iatrogenic, being associated with surgery for gallbladder stones. However,blunt abdominal trauma such as a motor vehicle crash is a rare cause of extrahepatic biliary stricture. A few reports have been published on biliary strictures treated with endoscopic therapy. In the present study, we describe a suprapancreatic biliary stricture associated with mesenteric tear following road traffic accident.We performed endoscopic stent placement, which was successful in relieving the biliary stricture.

  6. High-dose-rate afterloading intracavitary irradiation and expandable metallic biliary endoprosthesis for malignant biliary obstruction

    International Nuclear Information System (INIS)

    A double lumen catheter was developed as an applicator for the remote afterloading system (RALS) of 60Co 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)

    Liver transplantation is the optimal treatment formany patients with advanced liver disease, includingdecompensated cirrhosis, hepatocellular carcinomaand acute liver failure. Organ shortage is the maindeterminant of death on the waiting list and hence livingdonor liver transplantation (LDLT) assumes importance.Biliary complications are the most common post operativemorbidity after LDLT and occur due to anatomical andtechnical reasons. They include biliary leaks, stricturesand cast formation and occur in the recipient as well asthe donor. The types of biliary complications after LDLTalong with their etiology, presenting features, diagnosisand endoscopic and surgical management are discussed.

    Benign biliary strictures are common and occur either from hepato-biliary surgery or from diseases including chronic pancreatitis and primary sclerosing cholangitis, among others. The treatment of many such strictures is endoscopic with evolving new approaches especially with fully covered metal stents. The only classification system available is for postoperative strictures with the intention to guide surgical correction. There is no useful classification system to guide both assessment and management of benign biliary strictures. This proposed classification is relevant to patient care in assisting diagnosis and endoscopic management. PMID:26147976

  9. Metallic stents for management of malignant biliary obstruction

    International Nuclear Information System (INIS)

    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

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

    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).

    Ninety patients aged 21 to 56 years who had chronic non-calculous cholecystitis (CNCC) concurrent with hyperkinetic dyskinesia (HKD) detectable by a stepwise duodenal probing and sonography, by using a choleretic breakfast and by determining the relaxation coefficient (RC) that was equal to the ratio of the volume of the gallbladder (GB) after the use of a spasmolytic to the baseline GB volume. The patients were divided into 3 groups. The authors used as a spasmolytic agent pinaverium bromide (dicetel) in a dose of 50 mg (1 tablet) in Group 1), octylonium bromide (spasmomen) in a dose of 40 mg (1 dragee) in Group 2, and drotaverine (no-spa) in a dose of 40 mg (1 tablet). There was a more significant sonographic increase in the size of GB in Groups 1 and 2 as compared with Group 3. In the acute drug test and during long-term treatment as well, the highest spasmolytic effect was noted in patients receiving dicetel (Group 1) and spasmomen (Group 2) as compared with that in Group 3 patients taking drotaverine. With this, RC was 1.25 +/- 0.2, 1.6 +/- 0.15, and 1.08 +/- 0.1, respectively. No adverse reactions occurred in the patients having selective calcium blockers (SCBs) whereas the patients receiving no-spa were found to have the following side effects: dry mouth (n = 3), transient constipation (n = 1), and numb tongue (n = 1). Thus, the study has provided evidence for the fact that SCBs have some advantage over myotropic spasmolytic agents in the treatment of CNCC with the signs of HKD. PMID:15540426

    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.

  17. MRCP compared to diagnostic ERCP for diagnosis when biliary obstruction is suspected: a systematic review

    International Nuclear Information System (INIS)

    Magnetic resonance cholangiopancreatography (MRCP) is an alternative to diagnostic endoscopic retrograde cholangiopancreatography (ERCP) for investigating biliary obstruction. The use of MRCP, a non-invasive procedure, may prevent the use of unnecessary invasive procedures. The aim of the study was to compare the findings of MRCP with those of ERCP by the computation of accuracy statistics. Thirteen electronic bibliographic databases, covering biomedical, science, health economics and grey literature were searched. A systematic review of studies comparing MRCP to diagnostic ERCP in patients with suspected biliary obstruction was conducted. Sensitivity, specificity, likelihood ratios, acceptability and adverse events were reported. 25 studies were identified reporting several conditions including choledocholithiasis (18 studies), malignancy (four studies), obstruction (three studies), stricture (two studies) and dilatation (five studies). Three of the 18 studies reporting choledocholithiasis were excluded from the analysis due to lack of data, or differences in study design. The sensitivity for the 15 studies of choledocholithiasis ranged from 0.50 to 1.00 while specificity ranged from 0.83 to 1.00. The positive likelihood ratio ranged: from 5.44–47.72 and the negative likelihood ratio for the 15 studies ranged from 0.00–0.51. Significant heterogeneity was found across the 15 studies so the sensitivities and specificities were summarised by a Receiver Operating Characteristic (ROC) curve. For malignancy, sensitivity ranged from 0.81 to 0.94 and specificity from 0.92 to 1.00. Positive likelihood ratios ranged from 10.12 to 43 and negative likelihood ratios ranged from 0.15 to 0.21, although these estimates were less reliable. MRCP is a comparable diagnostic investigation in comparison to ERCP for diagnosing biliary obstruction

    Abstract The relationship between biliary tract inflammation (BTI) and digestive system cancers is unclear. This study aimed to evaluate the association between BTI and the risks of digestive system cancers. Using the Taiwan National Health Insurance claims data, information on a cohort of patients diagnosed with BTI (n = 4398) between 2000 and 2009 was collected. A comparison cohort of sex-, age-, and index year-matched persons without BTI (n = 17,592) was selected from the same database. The disease was defined by the ICD-9-CM. Both cohorts were followed until the end of 2010 and incidences of digestive system cancers were calculated. The results revealed an increase in adjusted hazard ratio (aHR) of biliary tract cancer (24.45; 95% confidence interval [CI]: 9.20–65.02), primary liver cancer (1.53; 95% CI: 1.07–2.18), and pancreatic cancer (3.10; 95% CI: 1.20–8.03) in patients with both gallbladder and BTI. The aHR of stomach cancer was also found to be increased (2.73; 95% CI: 1.28–5.81) in patients with gallbladder inflammation only. There were no differences in esophageal cancer (aHR: 0.82; 95% CI: 0.23–2.87) and colorectal cancer (aHR: 0.92; 95% CI: 0.59–1.45). The aHR for digestive system cancers increased by 3.66 times (95% CI: 2.50–5.35) and 12.20 times (95% CI: 8.66–17.17) in BTI visits frequency averaged 2 to 4 visits per year and frequency averaged ≥5 visits per year, respectively. Patients with BTI have significantly higher risk of digestive system cancers, particularly biliary tract, pancreatic, and primary liver cancers, compared with those who are without it. PMID:27495065

    AIM: To analyze the pathogenetic role and potential clinical usefulness of the epidermal growth factor receptor (EGFR) and the human epidermal growth factor receptor 2 (HER2) in patients with advanced biliary tract cancer (BTC). METHODS: EGFR and HER2 expression was studied in biopsy samples from 124 patients (51% women;median age 64.8 years), with advanced BTC diagnosed between 1997 and 2004. Five micrometers sections of paraffin embedded tissue were examined by standard, FDA approved immunohistochemistry. Tumors with scores of 2+ or 3+ for HER2 expression on immunochemistry were additionally tested for HER2 gene amplification by fluorescence in situ hybridisation (FISH).RESULTS: 34/124 patients (27.4%) had gallbladder cancer, 47 (37.9%) had intrahepatic BTC and 43 (34.7%) had extrahepatic or perihilar BTC. EGFR expression was examined in a subset of 56 samples. EGFR expression was absent in 22/56 tumors (39.3%).Of the remaining samples expression was scored as 1+ in 12 (21.5%), 2+ in 13 (23.2%) and 3+ in 9 (16%), respectively. HER2 expression was as follows: score 0 73/124 (58.8%), score 1+ 27/124 (21.8%), score 2+ 21/124 (17%) and score 3+ 4/124 (3.2%). HER2 gene amplification was present in 6/124, resulting in an overall amplification rate of 5%.CONCLUSION: Our data suggest that routine testing and therapeutic targeting of HER2 does not seem to be useful in patients with BTC, while targeting EGFR may be promising.

    Full Text Available Primary biliary cirrhosis (PBC is an autoimmune disease of unclear etiology. It is a chronic, progressive condition that causes intrahepatic ductal destruction ultimately leading to symptoms of cholestasis, cirrhosis and liver failure. The disease predominantly affects middle aged Caucasian women. It has a predilection to certain regions and is found in higher incidences in North America and Northern Europe. It also has a genetic predisposition with a concordance rate of 60% among monozygotic twins. Combinations of genetic and environmental factors are proposed in the pathogenesis of this disease with a compelling body of evidence that suggests a role for both these factors. This review will elucidate data on the proposed environmental agents involved the disease's pathogenesis including xenobiotic and microbial exposure and present some of the supporting epidemiologic data.

    2015-01-01

    Hilar biliary strictures are caused by various benign andmalignant conditions. It is difficult to differentiate benignand malignant strictures. Postcholecystectomy benignbiliary strictures are frequently encountered. Endoscopicmanagement of these strictures is challenging.Anendoscopic method has been advocated that involvesplacement of increasing number of stents at regularintervals to resolve the stricture. Malignanthilar stricturesare mostly unresectable at the time of diagnosis and onlypalliation is possible.Endoscopic palliation is preferredover surgery or radiological intervention. Magneticresonance cholangiopancreaticographyis quite importantin the managementof these strictures. Metal stents aresuperior to plastic stents. The opinion is divided over theissue of unilateral or bilateral stenting.Minimal contrastor no contrast technique has been advocated duringendoscopicretrograde cholangiopancreatography ofthese patients. The role of intraluminal brachytherapy,intraductal ablation devices, photodynamic therapy, andendoscopic ultrasound still remains to be defined.

    Benign biliary strictures are being increasingly treated with endoscopic techniques. The benign nature of the stricture should be first confirmed in order to ensure appropriate therapy. Surgery has been the traditional treatment, but there is increasing desire for minimally invasive endoscopic therapy. At present, endoscopy has become the first line approach for the therapy of postliver transplant anastomotic strictures and distal (Bismuth Ⅰ and Ⅱ) post-operative strictures. Strictures related to chronic pancreatitis have proven more difficult to treat,and endoscopic therapy is reserved for patients who are not surgical candidates. The preferred endoscopic approach is aggressive treatment with gradual dilation of the stricture and insertion of multiple plastic stents. The use of uncovered self expandable metal stents should be discouraged due to poor long-term results. Treatment with covered metal stents or bioabsorbable stents warrants further evaluation. This area of therapeutic endoscopy provides an ongoing opportunity for fresh research and innovation.

    Full Text Available Development of mini-invasive surgery determinates a rapid improvement in laparoscopic regional anatomy. As laparoscopy is becoming common in most surgical departments, basic laparoscopic anatomy is mandatory for all residents in general surgery. Successful general surgery starts in the anatomy laboratory. Successfully minim invasive surgery starts in the operative theatre with laparoscopic exploration. The initial laparoscopic view of the right upper quadrant demonstrates primarily the subphrenic spaces, abdominal surface of the diaphragm and diaphragmatic surface of the liver. The falciform ligament is a prominent dividing point between the left subphrenic space and the right subphrenic space. The ligamentum teres hepatis is seen in the free edge of the falciform. Upward traction on the gallbladder exposes the structures of Calot’s triangle and the hepatoduodenal ligament. The liver is divided into anatomic segments based on internal anatomy that is invisible to the laparoscopist. Surface landmarks include the falciform ligament and the gallbladder fossa. The surgical procedures performed laparoscopically currently include liver biopsy, wedge resection, fenestration of hepatic cysts, laparoscopic approach of the hidatid hepatic cyst, and atypical hepatectomy. We present the laparoscopic anatomy of extrahepatic biliary tract. Once the gallbladder is elevated, inspection reveals Hartmann’s pouch and the cystic duct. The typical angular junction of the cystic duct on the common duct actually occurs in a minority of patients and the length and course of the cystic duct are highly variable. The boundaries of Calot’s triangle are often not well seen. The cystic artery is often visible under the peritoneum as it runs along the surface of the gallbladder. The variations of the structures of the hepatoduodenal ligament may occur to injuries during laparoscopic cholecystectomy. Cholangiography increases the safety of dissection of biliary tract by

    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.

  6. Evidence-Based Decompression in Malignant Biliary Obstruction

    International Nuclear Information System (INIS)

    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.

    Mucin-hypersecreting biliary neoplasm excretes excessive mucin that fills the biliary tree and results in marked dilatation of the bile ducts and obstructive jaundice. In these neoplasm, the much produced by the tumor rather than the tumor itself plays an important role in clinical course and radiologic patterns. The purpose of this paper is to report characteristic radiologic patterns of mucin-hypersecreting biliary neoplasms in two cases. These neoplasms were characterized by not only multilocular cystic hepatic mass or extra-hepatic bile duct mass resulting in marked biliary dilatation distal to the mass on US or CT, but also change of shape and extent of amorphous filling defects in the markedly dilated bile duct on serial cholangiograms.

    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.

    Surgery of the biliary tract is demanding and is associated with several potentially life-threatening complications. Veterinarians face challenges in obtaining accurate diagnosis of biliary disease, surgical decision-making, surgical hemostasis and bile peritonitis. Intensive perioperative monitoring is required to achieve early recognition of common postoperative complications. Proper treatment and ideally, avoidance of surgical complications can be achieved by gaining a clear understanding physiology, anatomy, and the indications for hepatobiliary surgery.

    Biliary stenting via endoscopic retrograde cholangiopancreatography has greatly improved the quality of patient care over the last 30 years. Plastic stent occlusion limits the life span of such stents. Attempts to improve plastic stent patency duration have mostly failed. Metal stents (self-expandable metal stents [SEMSs]) have therefore replaced plastic stents, especially for malignant biliary strictures. SEMS are at least 10 times more expensive than plastic stents.

  2. Biliary excretion of iron and ferritin in idiopathic hemochromatosis

    International Nuclear Information System (INIS)

    The role of biliary excretion of iron and ferritin in iron overload was studied and evaluated. Ten patients with idiopathic hemochromatosis and two groups of controls (14 gallstone patients and 16 healthy subjects) were included. Liver tissue (obtained by percutaneous or operative biopsy) was investigated with light microscopy and transmission electron microscopy in combination with x-ray microanalysis. Fasting bile samples were obtained through duodenal aspiration or at cholecystectomy. Iron was determined in liver tissue and bile using atomic absorption spectroscopy, and ferritin was determined in serum and bile with a radioimmunoassay technique. All patients with hemochromatosis had iron-positive staining as seen in light microscopy. Electron microscopy showed iron-containing proteins in the lysosomes and cytosol of liver parenchymal cells, and this observation was supported by x-ray microanalysis. Hepatic iron concentration was increased about eightfold in the patients with hemochromatosis (p less than 0.001). Biliary iron concentration, expressed per millimole of bile acid, was increased about twofold (p less than 0.05) and biliary ferritin concentration about fivefold (p less than 0.001) in hemochromatosis. Four of the patients with hemochromatosis were reexamined after completed treatment with venesection; this resulted in normalized biliary concentrations of iron and ferritin. We conclude that biliary secretion of ferritin occurs in humans and that both iron and ferritin excretion are enhanced in hepatic iron overload. The apparently limited capacity of biliary iron excretion may be of importance for the hepatic iron accumulation in hemochromatosis

  3. Interventional treatment on vascular and biliary complications after liver transplantation

    International Nuclear Information System (INIS)

    Objective: To evaluate the value of angiography and cholangiography on the diagnosis and interventional treatment on vascular and biliary complications after liver transplantation. Methods: Sixteen of 46 patients (15 males, 1 female, 17-60 years old) after orthotopic liver transplantation received angiography due to abnormal ultrasonography or edema of lower limbs, or cholangiography due to progressing jaundice. 15 cases received angiography and proved vascular complications and 4 cases received cholangiography and biliary complications were found. 3 of them appeared both vascular and biliary complications. Results: Hepatic artery complication was the most common complication (seen in 9/16 patients), including hepatic artery thrombosis or stenosis (6/9), bleeding (2/9) and hepatic artery-dissecting aneurysm (1/9). One case with hepatic artery thrombosis received transcatheter thrombolysis and two cases with bleeding received coil embolization. Stenosis of inferior vena cava and portal vein were observed in 6 and 2 patients respectively. After balloon angioplasty or stent placement, clinical symptom of all cases alleviated. Biliary complications including biliary stricture and anastomotic bile leak occurred in 4 patients. Jaundice decreased after percutaneous transhepatic cholangiography and drainage. Conclusion: Interventional methods offered both diagnosis and mini-invasive treatment for patients after liver transplantation with vascular and biliary complications. Balloon angiography and stent placement of venous stenosis is an useful procedure for the treatment of these problems

    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.

    AIM To study the physico-chemical properties of biliary calculus and the relationship between the calculusformation and the phase change of liquid crystal, providing the best evidence for the biliary calculusprevention and treatment.METHODS The cholesterol contents in thirty one cases of biliary calculus in Kunming were determined bydouble-wave-length TLC scanning with high efficiency silica gel films.RESULTS Under magnifiers, the granular biliary calculus from 31 patients were classified according totheir section structures and colours, as cholesterol cholelith, 25 cases; bilirubin cholelith, 4 cases andcompound cholelith, 2 cases. By TLC scanning, it was found that the content of cholesterol in human biliarycalculus was 71%- 100%, about 80% cholesterol bilestones whose cholesterol content was more than 90%being pure cholesterol bilestones.CONCLUSION Cholesterol bilestone is the main human biliary calculus in Kunming, which was inaccordance with X-ray analysis. Compared with the related reports, it is proved that the proportion ofcholesterol bilestones to biliary calculus is increasing because of the improved life standard and the decreaseof bilirubin bilestones resulted from bile duct ascariasis or bacteria infection in China since 90s, and that theincrease of cholesterol in-take leads to the increase of cholesterol metabolism disorder

    Despite advances in patient and graft management,biliary complications(BC)still represent a challenge both in the early and delayed period after orthotopic liver transplantation(OLT).Because of unspecific clinical presentation,imaging is often mandatory in order to diagnose BC.Among imaging modalities,magnetic resonance cholangiography(MRC)has gained widespread acceptance as a tool to represent the reconstructed biliary tree noninvasively,using both the conventional technique(based on heavily T2-weighted sequences)and contrast-enhanced MRC(based on the acquisition of T1-weighted sequences after the administration of hepatobiliary contrast agents).On this basis,MRC is generally indicated to:(1)avoid unnecessary procedures of direct cholangiography in patients with a negative examination and/or identify alternative complications;and(2)provide a road map for interventional procedures or surgery.As illustrated in the review,MRC is accurate in the diagnosis of different types of biliarycomplications,including anastomotic strictures,nonanastomotic strictures,leakage and stones.

    Full Text Available Arun JeevaganGeneral Medicine, Ipswich NHS Hospital, Ipswich, UKBackground: Overlap syndrome has been introduced to the field of hepatology to describe the coexistence of two or more autoimmune hepatic conditions in the same individual. This is a rare clinical case of a patient diagnosed with primary biliary cirrhosis (PBC who later developed primary sclerosing cholangitis (PSC. This is a unique case as no other cases with a similar pattern have been reported. Overlap syndrome does not include the coexistence of PBC and PSC as a distinctive syndrome so far.Case report: A middle-aged woman suffering from PBC for 17 years got admitted with clinical and biochemical features of cholestatic syndrome. A provisional diagnosis of worsening PBC was proved wrong by magnetic resonance cholangiopancreatography, which revealed typical benign stricture and dilatation of common bile duct with typical beading appearance suggestive of PSC. The patient was stented and treated with an increased dose of ursodeoxycholic acid (UDCA which improved the symptoms and the biochemical picture.Conclusion: This is a clear overlap of PBC–PSC. It is very difficult to say whether it is a rare coincidence or a new overlap syndrome, but there are no clear guidelines for management of these patients. Currently, the treatment involves endoscopic duct dilatation, UDCA, and regular follow-ups to rule out hepato-biliary tumor occurrence.Keywords: primary biliary cirrhosis, primary sclerosing cholangitis, hepatic overlap syndrome

  9. Prognostic impact of hepatobiliary scintigraphy in diagnosis and postoperative follow-up of newborns with biliary atresia

    International Nuclear Information System (INIS)

    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.)

    Biliary-pancreatic-duodenal junction is a special region in the human body.It is difficult to diagnose and treat diseases in this region because of the complicated anatomy,the limitation of diagnosing methods,the variety of disease,the high risks of operation and the severity of complications. We should pay more attention to the pathophysiology aspects and the laboratory researches of diseases in this region.Proper diagnosis and combination of different diagnosing methods could improve the rate of early diagnosis and identify the characteristics of the disease. Individualized operation should be considered to deal with iatrogenic injury of biliary-pancreatic-duodenal junction according to different patients' condition.The principle of operation is to control damage firstly and to preserve the function of biliary-pancreatic-duodenal junction and the physiological passway of bile and pancreatic juice to the greatest extent.

    Specific markers for pancreatic or biliary cancer have been developed in the past few years. Ca 19-9 has a good sensitivity but it is also increased in benign cholestasis. Mutations in the p53 gene are commonly reported in pancreatic cancer and can be detected by a serological analysis. The aim of this work was to find out the sensitivity and specificity of this new assay in diagnosing cancer of the pancreas or of the bile ducts. The presence of antibodies against p53 was determined by an enz...

    2016-01-01

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

    AIM: To investigate the relationship between pancreatic amylase in bile duct and the clinico-pathological features in adult patients with choledochal cyst and anomalous pancreatico-biliary ductal union (APBDU).METHODS: From 39 patients who underwent surgery for choledochal cyst between March 1995 and March 2003,we selected 15 adult patients who had some symptoms and were radiologically diagnosed as APBDU, and their clinico-pathological features were subsequently evaluated retrospectively. However, we could not obtain biliary amylase in all the patients because of the surgeon's slip.Therefore, we measured the amylase level in gall bladder of 10 patients and in common bile duct of 11 patients.RESULTS: Levels of amylase in common bile duct and gall bladder ranged from 11 500 to 212 000 IU/L, and the younger the patients, the higher the biliary amylase level (r= -0.982, P<0.01). Pathologically, significant correlation was found between the size of choledochal cyst and the grade of inflammation (r= 0.798,P<0.01). And, significant correlation was found between the level of amylase in gall bladder and the grade of hyperplasia. On the other hand, there was no correlation to the age of symptomatic onset or inflammatory grade (r = 0.743, P<0.05). Level of lipase was elevated from 6 000 to 159 000 IU/L in bile duct and from 14 400 to 117 000 IU/L in the gall bladder;however, there was no significant correlation with age or clinico-pathological features.CONCLUSION: The results support the notion that amylase has a particular role in the onset of symptoms, and suggest that a large amount of biliary amylase induces early onset of symptom, thereby making early diagnosis possible.

    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.

    Objective To evaluate the method of palliative drainage by means of metallic indwelling stents or plastic tubes for patients with malignant biliary obstruction. Methods From January 1995 to Febuary 2001, 243 consecutive patients (161 men and 82 women; aged 26-91 years, mean of 61.3 years) with malignant biliary obstruction were treated with transhepatic placement of metallic stents and/or plastic tubes. Among them, 47 patients had pancreatic carcinoma, 98 cholangiocarcinoma, 28 metastatic carcinoma and 60 hepatic carcinoma. 169 stents of nine types were used in this series. After stenting, 47 patients were treated for local tumors. Procedure- and device-related complications were recorded. Patient survival and stent patency rates were calculated with Kaplan-Meier survival analysis.Results One hundred and three patients underwent successfully stent placement for the first time. Others had their stents installed 1-2 weeks after catheterization. Stents were used in 132 patients. Ninety-five patients were treated with a single stent. Seventeen patients had two stents installed for bilateral drainage,20 patients had two stents installed from top to bottom to create stenting of adequate ength, and 12 patients had stents placed across the ampulla. The 2-month mortality rate was 8.64% (21/243). Major complications occurred in two patients (0.8%, 2/243). Minor complications included self-limited bleeding into the drainage tubes and fever. The average patency of the initial stent was 7.5 months and average survival was 9 months. Thirteen patients received brachytherapy in their stents, 15 extra radiation therapy, and 19 intra-arterial infusion chemotherapy. The 47 patients treated for local tumors had an average survival of 11.3 months (log rank 32.8,P<0.001) with an average patency of 9.7 months(log rank 4.7,P<0.05).Conclusion Percutaneous transhepatic bile drainage as a palliative procedure is well tolerated by patients. After stenting, treatment for local tumor may

    Ectopic pancreas is a rare congenital malformation with pancreatic tissue in an aberrant location and not contiguous with the main gland. Patients suffering from ectopic pancreas usually have lesions in the stomach or duodenum[1,2]. Ectopic pancreatic tissue in the gallbladder is very rare, and only several cases have been reported[3-6]. We report one case of a 33-year-old man with ectopic pancreas presenting as repeatedly colic pain in the right upper quadrant of abdomen. He was first diagnosed as recurrent cholecys titis accompanied by biliary pancreatitis, but surgical pathology proved he suffered from cholecystitis and ectopic pancreas in the gallbladder wall, and the laparoscopic cholecystectomy led to relief.

    Autotaxin (ATX) is a 125-kD type II ectonucleotide pyrophosphatase/phosphodiesterase (ENPP2 or NPP2) originally discovered as an unknown "autocrine motility factor" in human melanoma cells. In addition to its pyrophosphatase/phosphodiesterase activities ATX has lysophospholipase D (lysoPLD) activity, catalyzing the conversion of lysophosphatidylcholine (LPC) into lysophosphatidic acid (LPA). ATX is the only ENPP family member with lysoPLD activity and it produces most of the LPA in circulation. In support of this, ATX heterozygous mice have 50% of normal LPA plasma levels. The ATX-LPA signaling axis plays an important role in both normal physiology and disease pathogenesis and recently has been linked to pruritus in chronic cholestatic liver diseases, including primary biliary cholangitis (PBC). Several lines of evidence have suggested that a circulating puritogen is responsible, but the identification of the molecule has yet to be definitively identified. In contrast, plasma ATX activity is strongly associated with pruritus in PBC, suggesting a targetable molecule for treatment. We review herein the biochemistry of ATX and the rationale for its role in pruritus.

  8. Biliary tract obstruction secondary to Burkitt lymphoma

    International Nuclear Information System (INIS)

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

    Primary biliary cirrhosis(PBC) is a chronic non-suppurative destructive intrahepatic cholangitis leading to cirrhosis after a protractive non cirrhotic stage. The etiology and pathogenesis are largely unknown and autoimmne mechanisms have been implicated to explain the pathological lesions. Many epitopes and autoantigens have been reported as crucial in the pathophysiology of the disease and T and B cells abnormalities have been described, the exact pathways leading to the destruction of small intrahepatic ductules are mostly speculative. In this review we examined the various epidemiologal and geoepidemiological data as well as the complex pathogenetic aspects of this disease, focusing on recent in vivo and in vitro studies in this field. Initiation and progression of PBC is believed to be a multifactorial process with strong infuences from the patient’s genetic background and by various environmental factors. The role of innate and adaptive immunity, including cytokines, chemokines, macrophages and the involvement of apoptosis and reactive oxygen species are outlined in detailed. The current pathogenetic aspects are presented and a novel pathogenetic theory unifying the accumulated clinical information with in vitro and in vivo data is formulated. A review of clinical manifestations and immunological and pathological diagnosis was presented. Treatment modalities, including the multiple mechanisms of action of ursodeoxycholate were finally discussed.

  10. Successful Endoscopic Ultrasound-Guided Transduodenal Biliary Drainage Through a Pre-Existing Duodenal Stent

    2010-05-01

    Full Text Available Context When ERCP fails in the setting of combined biliary and duodenal obstruction, EUS-guided biliary drainage has emerged as an alternate method of biliary decompression. Case report We present a case of a 40-year-old man with advanced pancreatic cancer and a pre-existing duodenal wall stent who subsequently develops jaundice due to biliary obstruction. An ERCP was technically unsuccessful as the papilla was inaccessible despite probing within the duodenal stent. Transduodenal biliary drainage was achieved using EUS guidance to create a choledochoduodenostomy tract. A fully covered metal biliary stent was then deployed through the mesh of the duodenal wall stent. The patient’s jaundice and pruritus subsequently resolved. Conclusion This is the first report of successful transduodenal EUS-guided biliary drainage performed through an existing enteral wall stent and can still be considered as an alternate mode of biliary drainage in this setting.

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

    1993-01-01

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

  13. Management of complications during percutaneous implementation of biliary stents

    International Nuclear Information System (INIS)

    Objective: To retrospectively analyze the complications and management of complications during percutaneous implementation of biliary stents in 17 patients. Methods: Percutaneous biliary drainage and implementation of biliary stents for malignant biliary obstruction under fluoroscopic guidance was performed in 64 patients. 17 cases developed complications. Bradycardia and hypotension was seen in 5 cases, slipping of the stent into the duodenum in 1, bile duct perforation in 2, the fine guidewire broken in the hepatic parenchyma in 2, malposition of the stent in 3, hepato-renal failure leading to hemorrhage in 2, exchanging guidewire broken in the duodenum in 1, and balloon broken leading to stent dislocation in 1, respectively. Results: Bradycardia and hypotension in the 5 cases was treated medically and the procedure was interrupted. Slipping of the stent into the duodenum was passed off spontaneously. Broken of the fine guidewire in the liver did not present any complaints until the death of the patients. Perforation of bile duct was treated conservatively with a clinical successful outcome. Malposition of the stent was treated by reimplementation of shorter stents. The broken exchanging guidewire in the duodenum during implementation was removed with the gastroscope. The hepato-renal failure leading to hemorrhage had poor prognosis. The broken balloon caused stent dislocation was treated by reimplementation of stent. Conclusion: Percutaneous implementation of stent is effective and safe for elderly patients with proximal stenosis of the biliary tract. However, one must be very careful to avoid the complications

  14. The clinical application of domestic biliary metallic stents

    International Nuclear Information System (INIS)

    Objective: To determine the clinical efficacy and safety of domestic biliary metallic stents in the management of biliary obstruction. Methods: 75 domestic biliary metallic stents were implanted in 66 of 72 patients with obstructive jaundice due to malignant (n=70) and benign stenoses (n=2). Results: The technical successful rate was 92.7% (64/66). Palliation with rid of jaundice was achieved in 96.9% (64/66) within 1 month. The 30-day mortality rate was 3% (2/66). Early complications occurred in 7.6% (5/66). 44 patients were followed from 2 to 24 months after treatment. 33 (33/42) of 42 patients with malignancy died after a median survival of 5.3 months (range 2-23 months). The remaining 9 patients (9/42) remained alive with a mean follow-up of 11.6 months. The stent patency rates were 92.8%, 89.9% and 79.4 % at 3, 6, 12 months respectively. 6 patients (6/42) presented stent occlusion within a median period of 3 months. One of two patients with benign stenoses sustained a patency duration time of 24 months. One patient died 3 months after treatment. Conclusions: The domestic biliary metallic stent implantation is efficacy and safety in the management of biliary obstruction. (authors)

  15. Contrast-free endoscopic stent insertion in malignant biliary obstruction

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    AIM: To present a case series of MRCP-guided endoscopic biliary stent placement, performed entirely without contrast injection.METHODS: Contrast-free endoscopic biliary drainage was attempted in 20 patients with malignant obstruction,unsuitable for resection on the basis of tumor extent or medical illness. MRCP images were used to confirm the diagnosis of tumor, to exclude other biliary diseases and to demonstrate the stenoses as well as dilation of proximal liver segments. The procedure was carried out under conscious sedation. Patients were placed in the left lateral decubitus position. The endoscope was inserted, the papilla identified and cannulated by a papillotome. A guide wire was inserted and guided deeply into the biliary tree, above the stenosis, by fluoroscopy. A papillotomy approximately 1 cm. long was performed and the papillotome was exchanged with a guiding-catheter. A 10 Fr, Amsterdam-type plastic stent,7 to 15 cm long, was finally inserted over the guide wire/guiding catheter by a pusher tube system.RESULTS: Successful stent insertion was achieved in all patients. There were no major complications. Successful drainage, with substantial reduction in bilirubin levels,was achieved in all patients.CONCLUSION: This new method of contrast-free endoscopic stenting in malignant biliary obstruction is a safe and effective method of palliation. However, a larger, randomized study comparing this new approach with the standard procedure is needed to confirm the findings of the present study.

    Endoscopic biliary stent insertion is a well-established procedure. It is especially successful in treating postoperative biliary leaks, and may prevent surgical intervention. A routine change of endoprostheses after 3 mo is a common practice but this can be prolonged to 6 mo. We reported a colonic perforation due to biliary stent dislocation and migration to the rectosigmoid colon, and reviewed the literature.

  3. Acute Duodenal Obstruction After Percutaneous Placement of Metallic Biliary Stents: Peroral Treatment with Enteral Stents

    International Nuclear Information System (INIS)

    Three patients with malignant biliary obstruction were treated with placement of metallic biliary stents. Two patients had known partial duodenal stenosis but had no symptoms of gastrointestinal obstruction. The patients developed symptomatic duodenal obstruction early after biliary metallic stent placement. The symptomatic duodenal obstructions were successfully treated with peroral placement of duodenal stents, which obviated the need for surgical intervention

  5. The application of biliary catheter folding technique in the treatment of hilar nonanastomotic biliary strictures after orthotopic liver transplantation

    International Nuclear Information System (INIS)

    Objective: To introduce a newly-designed percutaneous single catheter folding technique, by which bilateral biliary drainage and stenting can be completed through single access, and to assess the effectiveness and safety of this technique in treating hilar nonanastomotic strictures occurred after orthotopic liver transplantation. Methods: A total of 10 patients with nonanastomotic strictures, who were encountered during the period from July 2000 to July 2010 in authors' hospital, were enrolled in this study. Balloon dilatation was used for the biliary tract stenosis. After the placement of biliary drainage tube, the catheter was folded into 'Y' shape within the biliary duct at hepatic portal region, and triaxial supporting drainage, i.e. the left hepatic duct, the right hepatic duct and the common hepatic duct, was established. The technical success rate, the clinical efficacy, the complications and the recurrence were documented and analyzed. Results: Technical success rate was 100% (10/10). In 9 patients, the clinical symptoms were obviously relieved, the biochemical indexes were gradually restored to normal and the imaging findings were markedly improved. During the follow-up lasting 26 months (median), no recurrence was seen. Minor complications occurred in two cases. One patient died after he received second orthotopic liver transplantation because of failure to respond to initial treatment. Conclusion: Percutaneous transhepatic biliary catheter folding technique is technically feasible. The results of this study indicate that this technique carries satisfactory success rate and is very effective and safe for the treatment of hilar nonanastomotic strictures occurred after orthotopic liver transplantation.

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

    When endoscopic retrograde cholangio-pancreatog-raphy fails to decompress the pancreatic or biliary system, alternative interventions are required. In this situation, endosonography guided cholangio-pancrea-tography(ESCP), percutaneous radiological therapy or surgery can be considered. Small case series reporting the initial experience with ESCP have been superseded by comprehensive reports of large cohorts. Although these reports are predominantly retrospective, they demonstrate that endoscopic ultrasound(EUS) guided biliary and pancreatic interventions are associated with high levels of technical and clinical success. The proce-dural complication rates are lower than those seen with percutaneous therapy or surgery. This article describes and discusses data published in the last five years relat-ing to EUS-guided biliary and pancreatic intervention.

    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.

    Objective: To study the techniques of placement of memory alloy plating gold biliary stent and plastic stent for palliation of malignant and benign biliary obstruction, and to assess its clinical effectiveness. Methods: The patients in plastic stent group included paplilla of duodenum inflamational strictures (n=24), common bile duct inflammational inferior segment strictures (n=4), choledocholithiasis (n=5), bile leak (n=11), bile duct surgery injurey (n=7) and pancreatic carcinoma (n=1). The patients in plating gold stent group included common bile duct carcinoma (n=5) and pancreatic carcinoma (n=6). Under fluoroscopic guidance the stent was inserted into biliary obstruction sites from oral cavity in all cases. Complications, liver function and blood serum amylase were investigated during the study period. Results: Successful stent placement was achieved in all cases. After operation of 7 days, in gold biliary stent groups, the rates of decrease of blood serum total bilirubin, glutamic-pyruvic transaminase, r-glutamyl transpeptidase and alkaline phosphatase were 67.16%, 58.37%, 40.63% and 41.54% respectively. In plastic stent group, the rates of decrease of STB, ALT, r-GT and AKP were 53.24%, 55.03%, 37.15%, 34.12% respectively. Early complication included post-ERCP pancreatitis and cholangititis. Occlusion of stent was the major late complication. Conclusion: Memory alloy plating gold biliary stent and plastic stent were safe and efficacious methods for malignant and benign biliary obstruction, and could improve patient's living quality. Plastic stent was an efficient complement for therapy of bile leak and bile duct injury.

    Self-expandable metal stents (SEMS) are the current standard of care for the palliative management of malignant biliary strictures. Recently, endoscopic ablative techniques with direct affect to local tumor have been developed to improve SEMS patency. Several reports have demonstrated the technical feasibility and safety of intraductal radiofrequency ablation (RFA), by both endoscopic and percutaneous approaches, in palliation of malignant strictures of the bile duct. Intraductal RFA has also been used in the treatment of occlusion of both covered and uncovered SEMS occlusion from tumor ingrowth or overgrowth. This article provides a comprehensive review of intraductal RFA in the management of malignant biliary obstruction.

    Gallstones represent the most frequent aetiology of acute pancreatitis in many statistics all over the world, estimated between 40%-60%. Accurate diagnosis of acute biliary pancreatitis (ABP) is of outmost importance because clearance of lithiasis [gallbladder and common bile duct (CBD)] rules out...... for the intraoperative diagnosis of choledocholithiasis. Routine exploration of the CBD in cases of patients scheduled for cholecystectomy after an attack of ABP was not proven useful. A significant rate of the so-called idiopathic pancreatitis is actually caused by microlithiasis and/or biliary sludge. In conclusion...

    2016-03-01

    Biliary stenting via endoscopic retrograde cholangiopancreatography has greatly improved the quality of patient care over the last 30 years. Plastic stent occlusion limits the life span of such stents. Attempts to improve plastic stent patency duration have mostly failed. Metal stents (self-expandable metal stents [SEMSs]) have therefore replaced plastic stents, especially for malignant biliary strictures. SEMS are at least 10 times more expensive than plastic stents. In this focused review, we will discuss basic mechanisms of plastic stent occlusion, along with a systematic summary of previous efforts and related studies to improve stent patency and potential new techniques to overcome existing limitations.

    Primary biliary cirrhosis is an uncommon disease amongst Malaysians. Over a 12-year period, between 1979 and 1991, only seven patients with clinical, biochemical and histologic evidence of primary biliary cirrhosis were identified in University Hospital Kuala Lumpur. All were Chinese females between the ages of 30 to 55 years. The presenting complaint was pruritus in 5 patients. All except one patient was jaundiced when the diagnosis was made. These patients were followed up from 1 to 11 years. Three deaths were reported, one from massive hemetemesis and two from liver failure.

  16. Interventional treatment of biliary stent restenosis: recent progress in clinical management

    International Nuclear Information System (INIS)

    Malignant obstructive jaundice is biliary obstruction disorders which are caused by various malignant tumors. Usually the disease is at its advanced stage and is inoperable when the diagnosis is confirmed. At present, percutaneous transhepatic biliary drainage (PTCD) and endoscopic or interventional implantation of plastic or self-expanding metal stent (SEMS) are the main managements in clinical practice. Due to the improved survival time, biliary stent restenosis has become a quite common clinical problem. Photodynamic therapy (PDT) and biliary tract radiofrequency ablation (RFA) have provided new therapeutic means for clinical use. Especially, with its development in technology and equipment, RFA has played more and more important role in treating biliary stent restenosis. (authors)

  17. The observation and nursing of patients receiving interventional management for biliary complications occurred after liver transplantation

    International Nuclear Information System (INIS)

    Objective: To discuss the perioperative nursing norm for patients who are suffering from biliary complications occurred after liver transplantation and who will receive interventional management to treat the complications. Methods: Interventional therapies were performed in 20 patients with biliary complications due to liver transplantation. The interventional procedures performed in 20 cases included percutaneous biliary drainage (n = 13), percutaneous biliary balloon dilatation (n = 5) and biliary stent implantation (n = 7). The clinical results were observed and analyzed. Results: Biliary tract complications occurred after liver transplantation were seen frequently. Proper interventional management could markedly improve the successful rate of liver transplantation and increase the survival rate of the patients. In accordance with the individual condition, proper nursing measures should be taken promptly and effectively. Conclusion: Conscientious and effective nursing can contribute to the early detection of biliary complications and, therefore, to improve the survival rate of both the transplanted liver and the patients.

    International Nuclear Information System (INIS)

    Objective: To evaluate the effect of PTBD in treating malignant biliary obstruction caused by hilar cholangiocarcinoma. Methods: We retrospectively analyzed the data of 103 patients(M:62,F:41)with malignant obstructive jaundice caused by hilar cholangiocarcinoma. After taking percutaneous transhepatic cholangiography, metallic stent or plastic external catheter or external-internal catheter for drainage was deployed and then followed up was undertaken with clinical and radiographic evaluation and laboratory. examination. Results: All patients went though PTBD successfully (100%). According to Bismuth classification, all 103 cases consisted of I type(N=30), II type (N=30), III type (N=26) and IV type (N=17). Thirty-nine cases were placed with 47 stents and 64 eases with drainage tubes. 4 cases installed two stems for bilateral drainage, 2 cases installed two stents because of long segmental strictures with stent in stent, 1 case was placed with three stents, and 3 cases installed stent and plastic catheter together. Sixty-four cases received plastic catheters in this series, 35 cases installed two or more catheters for bilateral drainage, 28 cases installed external and internal drainage catheters, 12 eases installed external drainage catheters, and 24 eases installed both of them. There were 17 patients involving incorporative infection before procedure, 13 cases cured after procedure, and 15 new patients got inflammation after procedure. 13 cases showed increase of amylase (from May, 2004), 8 eases had bloody bile drainage and 1 case with pyloric obstruction. Total serum bilirubin reduced from (386 ± 162) μmol/L to (161 ± 117) μmol/L, (P<0.01) short term curative effect was related with the type of hilar cholangiocarcinoma. The survival time was 186 days(median), and 1, 3, 6, 12 month survival rate were 89.9%, 75.3%, 59.6%, 16.9%, respectively. Conclusion: Percutaneous transhepatic bile drainage is a safe and effective palliative therapy of malignant

    This study assessed the effect of pancreatico-biliary reflux (PBR) as co-factor in the process of chronic cholecystitis by measurement of the levels of active pancreatic enzyme amylase in gallbladder bile and serum of patients undergoing cholecystectomy. Pancreatic Amylase levels in bile from the gallbladder and serum were measured during surgery in 68 patients with chronic calcular cholecystitis subjected to elective open or laparoscopic cholecystectomy in the National Hepatology and Tropical Medicine Research Institution and Theodore Bilharz Research Institute. Bile amylase was detected in 64 patients (94.1%) indicating pancreatico-biliary reflux. Biliary amylase level ranged from 20-50 IU/L in 42 patients (61.76%), below 20 IU/l in 14 patients (20.59%), over 50 IU/L in 8 patients (11.76%) and undetectable in two patients. According to gallbladder bile amylase, the incidence of Occult PBR in patients operated upon for chronic calcular cholecystitis was 94.1%. The reason should be clarified by further research and wider scale study. Routinely investigating biliary amylase in every patient having cholecystitis can be a method for early detection of precancerous lesions.

    Intraoperative manometry of the biliary tract and measurement of amylase levels in choledochal cysts were performed in seven patients, aged 14 months to 5 years, with choledochal cysts, in an investigation of the pathophysiology of the biliary tract. An abnormal choledochopancreatico ductal junction was observed in these seven patients by preoperative endoscopic retrograde cholangiopancreaticography (ERCP) or intraoperative cholangiograms. All six patients examined showed a high amylase level in the choledochal cyst (5,450 to 46,500 Somogyi Units). The intraoperative manometry of the biliary tract showed that a remarkable high pressure zone as was found in the area of sphincter of Oddi was not found in the area of abnormal choledochopancreatico ductal junction. The pressure recordings also demonstrated that the sphincter of Oddi pressure in the patient with choledochal cyst was increased by gastrin stimulation. On the contrary, no pressure reaction to gastrin or secretin was found in the area of abnormal choledochopancreatic ductal junction. From these results it seems that free reflux of pancreatic juice into the biliary system occurs, and the reflux stream depends upon the pressure gradient between pancreatic ductal pressure and common bile duct pressure because of the lack of a sphincter function at the choledochopancreatico ductal junction.

    Five hundred patients with acute right-upper-quadrant pain underwent biliary scintigraphy with /sup 99m/Tc paraisopropyliminodiacetic acid. One hundred and thirty-four studies were reported normal (both gallbladder and activity in bowel are noted in 1 hr). Of the 134 studies reported as normal, 32 showed intestinal activity before gallbladder visualization during the first hour of the study. Sonography and/or oral cholecystography revealed that 24 patients had gallstones, and eight patients had no demonstrable pathology in the biliary system. Of the 134 studies, 102 showed visualization of the gallbladder before intestinal activity during the first hour of the study. Sonography and/or oral cholecystography showed that 73 patients had normal biliary system. The remaining 29 patients had gallstones. The overall sensitivity of this finding is 45%, the specificity is 90%, and the accuracy is 73%. In this group of symptomatic patients, the appearance of intestinal activity before gallbladder activity on biliary scintigraphy warrants further evaluation of these patients by sonography and/or oral cholecystography.

  5. Percutaneous transhepatic biliary drainage: analysis of 175 cases

    International Nuclear Information System (INIS)

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

    Cholelithiasis is the most common cause of acute pancreatitis, accounting 35%-60% of cases. Around 15%-20% of patients suffer a severe attack with high morbidity and mortality rates. As far as treatment is concerned, the optimum method of late management of patients with severe acute biliary pancreatitis is still contentious and the main question is over the correct timing of every intervention. Patients after recovering from an acute episode of severe biliary pancreatitis can be offered alternative options in their management, including cholecystectomy, endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy, or no definitive treatment. Delaying cholecystectomy until after resolution of the inflammatory process, usually not earlier than 6 wk after onset of acute pancreatitis, seems to be a safe policy. ERCP and sphincterotomy on index admission prevent recurrent episodes of pancreatitis until cholecystectomy is performed, but if used for definitive treatment, they can be a valuable tool for patients unfit for surgery. Some patients who survive severe biliary pancreatitis may develop pseudocysts or walled-off necrosis. Management of pseudocysts with minimally invasive techniques, if not therapeutic, can be used as a bridge to definitive operative treatment, which includes delayed cholecystectomy and concurrent pseudocyst drainage in some patients. A management algorithm has been developed for patients surviving severe biliary pancreatitis according to the currently published data in the literature. PMID:27678352

    Preoperative biliary drainage(PBD) was developed to improve obstructive jaundice, which affects a number of organs and physiological mechanisms in patients waiting for surgery. However, its role in patients who will undergo pancreaticoduodenectomy for biliary obstruction remains controversial. This article aims to review the current status of the use of preoperative drainage for distal biliary obstruction. Relevant articles published from 1980 to 2015 were identified by searching MEDLINE and Pub Med using the keywords "PBD", "pancreaticoduodenectomy", and "obstructive jaundice". Additional papers were identified by a manual search of the references from key articles. Current studies have demonstrated that PBD should not be routinely performed because of the postoperative complications. PBD should only be considered in carefully selected patients, particularly in cases where surgery had to be delayed. PBD may be needed in patients with severe jaundice, concomitant cholangitis, or severe malnutrition. The optimal method of biliary drainage has yet to be confirmed. PBD should be performed by endoscopic routes rather than by percutaneous routes to avoid metastatic tumor seeding. Endoscopic stenting or nasobiliary drainage can be selected. Although more expensive, the use of metallic stents remains a viable option to achieve effective drainage without cholangitis and reintervention.

    AIM: To evaluate the influence of preoperative biliary drainage on morbidity and mortality after surgical resection for ampullary carcinoma. METHODS: We analyzed retrospectively data for 82 patients who underwent potentially curative surgery for ampullary carcinoma between September 1993 and July 2007 at the Singapore General Hospital, a tertiary referral hospital. Diagnosis of ampullary carcinoma was confirmed histologically. Thirty-five patients underwent preoperative biliary drainage (PBD group), and 47 were not drained (non-PBD group). The mode of biliary drainage was endoscopic retrograde cholangiopancreatography ( n = 33) or percutaneous biliary drainage ( n = 2). The following parameters were analyzed: wound infection, intra-abdominal abscess, intra-abdominal or gastrointestinal bleeding, septicemia, biliary or pancreatic leakage, pancreatitis, gastroparesis, and re-operation rate. Mortality was assessed at 30 d (hospital mortality) and also longterm. The statistical endpoint of this study was patient survival after surgery. RESULTS: The groups were wel l matched for demographic criteria, clinical presentation and operative characteristics, except for lower hemoglobin in the non- PBD group (10.9 ± 1.6 vs 11.8 ± 1.6 in the PBD group). group (10.9 ± 1.6 vs 11.8 ± 1.6 in the PBD group). Of the parameters assessing postoperative morbidity, incidence of wound infection was significantly less in the PBD than the non-PBD group [1 (2.9%) vs 12 (25.5%)]. However, the rest of the parameters did not differ significantly between the groups, i.e. sepsis [10 (28.6%) vs 14 (29.8%)], intra-abdominal bleeding [1 (2.9%) vs 5 (10.6%)], intra-abdominal abscess [1 (2.9%) vs 8 (17%)], gastrointestinal bleeding [3 (8.6%) vs 5 (10.6%)], pancreatic leakage [2 (5.7%) vs 3 (6.4%)], biliary leakage [2 (5.7%) vs 3 (6.4%)], pancreatitis [2 (5.7%) vs 2 (4.3%)], gastroparesis [6 (17.1%) vs 10 (21.3%)], need for blood transfusion [10 (28.6%) vs 17 (36.2%)] and re-operation rate [1 (2

    Full Text Available Pulmonary embolism (PE is a common, treatable, highly lethal emergency, which despite advances in diagnostic testing, remains an under diagnosed killer. The mortality rate of diagnosed and treated pulmonary embolism ranges from 3-8%, but increases to about 30% in untreated pulmonary embolism. PE is a part of the spectrum of venousthromboembolic disease and most pulmonary emboli have their origin from clots in the iliac, deep femoral, or popliteal veins. Nonspecific clinical signs and symptoms with low sensitivity and specificity of routine tests such as arterial blood gas, chest roentgenogram and electrocardiogram make the diagnosis of PE very challenging for the clinician. Pulmonary angiography is the gold standard diagnostic test, but this technique is invasive, expensive, not readily available and labor intensive. Diagnostic strategies have revolved around establishing clinical probabilities based on predictive models, then ruling in or ruling out the diagnosis of PE with various tests. The aim of this article was to review the literature and present an evidence- based medicine approach to diagnosis of pulmonary embolism.

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

    AIM: To discuss about the perioperative problems encountered in patients with internal biliary fistula (IBF)caused by cholelithiasis.METHODS: In our hospital, 4130 cholecystectomies were carried out for symptomatic cholelithiasis from January 2000 to March 2004 and only 12 patients were diagnosed with IBF. The perioperative data of these 12IBF patients were analyzed retrospectively.RESULTS: The incidence of IBF due to cholelithiasis was nearly 0.3%. The mean age was 57 years.Most of the patients presented with non-specific complaints. Only two patients were considered to have IBF when gallstone ileus was observed during the investigations. Nine patients underwent emergency laparotomy with a pre-operative diagnosis of acute abdomen. In the remaining three patients, elective laparoscopic cholecystectomy was converted to open surgery after identification of IBF. Ten patients had cholecystoduodenal fistula and two patients had cholecystocholedochal fistula. The mean hospital stay was 13 d. Two wound infections, three bile leakages and three mortalities were observed.CONCLUSION: Cholecystectomy has to be performed in early stage in the patients who were diagnosed as cholelithiasis to prevent the complications like IBF which is seen rarely. Suspicion of IBF should be kept in mind, especially in the case of difficult dissection during cholecystectomy and attention should be paid in order to prevent iatrogenic injuries.

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

    We report a case of postoperative refractory bile leakage managed successfully by intrahepatic biliary ablation with ethanol. A 75-year-old man diagnosed with hepatocellular carcinoma underwent extended posterior segmentectomy including the caudate lobe and a part of the anterior segment. The hepatic tumor attached to the anterior branch of the bile duct was detached carefully and resected. Fluid drained from the liver surface postoperatively contained high concentrations of total bilirubin, at a constant volume of 150 mL per day. On d 32 after surgery, a fistulogram of the drainage tube demonstrated an enhancement of the anterior bile duct.Endoscopic retrograde cholangiography demonstrated complete obstruction of the proximal anterior bile duct and no enhancement of the peripheral anterior bile duct.On d 46 after surgery, a retrograde transhepatic biliary drainage (RTBD) tube was inserted into the anterior bile duct under open surgery. However, a contrast study of RTBD taken 7 mo post-surgery revealed that the fistula remained patent despite prolonged conservative management, so we decided to perform ethanol ablation of the isolated bile duct. Four mL pure ethanol was injected into the isolated anterior bile duct for ten minutes, the procedure being repeated five times a week. Following 23 attempts, the volume of bile juice reached less than 10 mL per day. The RTBD was clamped and removed two days later. After RTBD removal, the patient had no complaints or symptoms. Follow-up magnetic resonance imaging demonstrated atrophy of the ethanol-injected anterior segment without liver abscess formation.

However when the bilirubin exceed 10.5 mg/dl the time of visualization between protected reaching a flat curve or plateau around 10.5 mg/dl . The biliary tract could not be visualized when the bilirubin was higher than 10.5 mg/dl. The biliary tract could not be visualized demonstration and serum alkaline phosphatase was less strong and between scintigraphic demonstration and SGOT and SGPT was rather poor. The present clinical study confirmed the usefulness and limitation of {sup 99m}Tc-EHIDA hepatobiliary scintigraphy in visualizing and diagnosing the biliary system and duodenum when radiography and ultrasonography failed to provide useful information. Scintigraphy wa very helpful in the diagnosis of neonatal hepatitis, biliary atresia, cholecystitis and extrahepatic biliary obstruction. The hepatobiliary system and duodenum were visualized when serum bilirubin level was less than 10.5 mg/dl, SGOT 135 units, SGPT 114 units and alkaline phosphatase 52.2 KAU.

  5. Interval Biliary Stent Placement Via Percutaneous Ultrasound Guided Cholecystostomy: Another Approach to Palliative Treatment in Malignant Biliary Tract Obstruction

    International Nuclear Information System (INIS)

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

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

  8. Early diagnosis of intrahepatic biliary injury by DIC-CT, complicating the non-operative management of blunt liver trauma

    International Nuclear Information System (INIS)

    Of the patients with a blunt liver injury who were admitted to our hospital over a period of 2 years and 5 months, the subjects enrolled in the present study were 15 patients diagnosed with CT as having liver injury, and who underwent drip infusion cholangiography (DIC)-CT intended to diagnose intrahepatic biliary injury (IHBI) in its early stages. These 15 patients included 11 with a type IIIb injury and 4 with a type Ib injury. All of 5 patients with the type IIIb injury who underwent transcatheter arterial embolization (TAE) were found to have some signs of IHBI on DIC-CT. Of these patients, 2 were found to have extrahepatic leakage and underwent local drainage; 1 also underwent ENBD and was discharged. Three patients were not found to have extrahepatic leakage even though they were found to have signs of HIBI; the 3 underwent conservative therapy with no other care and had a satisfactory course. In 6 patients with a type IIIb injury and without TAE, only 1 patient was found to have IHBI, but without extrahepatic leakage. Comparison of two groups, with or without TAE, in type IIIb injury, the former had a higher Injury Severity Score (ISS) and higher incidence of IHBI on DIC-CT. No TAE was needed and no sign of IHBI was found in type Ib injury patients. DIC-CT may, in cases of severe liver injury that might require TAE, help to diagnose IHBI in its early stages. Our strategy, namely performing an early examination and drainage when the extrahepatic biliary leakage is found, seemed to be adequate. (author)

    AIM: To investigate the presence of Helicobacter species by nested PCR of 16S rRNA genes followed by the presence of Helicobacter pylori (H pylori) 16S rRNA, ureA, cagA genes in bile obtained at endoscopic retrograde cholangio-pancreatography (ERCP) from 60Indian subjects.METHODS: Sixty bile samples were obtained from patients diagnosed with various hepato-biliary diseases and control subjects at ERCP. PCR analysis was carried out using primers for Helicobacter genus 16S rRNA gene and H pylori(16S rRNA, ureA and caaA) genes. Gastric Hpyloristatus was also assessed from biopsies obtained at endoscopy from patients with various hepato-biliary diseases and controls. The control group mainly consisted of subjects with gastric disorders. Sequencing analysis was performed to confirm that PCR products with 16S rRNA and cagA primers were derived from H pylori.RESULTS No Helicobacters were grown in culture from the bile samples. Helicobacter DNA was detected in bile of 96.7% and 6.6% of groups Ⅰ and Ⅱ respectively. Ten from group Ⅰ were positive for 16S rRNA and ureA and 9were positive for cagA gene. In contrast of the 2 from the control, 1 amplified with 16S rRNA, ureA and cagA primers used. The sequences of the 16S rRNA genes and cagA were 99% similar to Helicobacter pylori.CONCLUSION: Helicobacters are associated with the pathogenesis of various hepato-biliary disorders.

    Biliary obstruction is a common clinical manifestation of various conditions, including extrahepatic cholangiocarcinoma. However, a screening test for diagnosis of extrahepatic cholangiocarcinoma in patients with biliary obstruction is not yet available. According to the rationale that the biliary system plays a major role in lipid metabolism, biliary obstruction may interfere with lipid profiles in the body. Therefore, plasma lipidomics may help indicate the presence or status of disease in biliary obstruction suspected extrahepatic cholangiocarcinoma. This study aimed to use plasma lipidomics for diagnosis of extrahepatic cholangiocarcinoma in patients with biliary obstruction. Plasma from healthy volunteers, patients with benign biliary obstruction extrahepatic cholangiocarcinoma, and other related cancers were used in this study. Plasma lipids were extracted and lipidomic analysis was performed using matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Lipid profiles from extrahepatic cholangiocarcinoma patients showed significant differences from both normal and benign biliary obstruction conditions, with no distinction between the latter two. Relative intensity of the selected lipid mass was able to successfully differentiate all extrahepatic cholangiocarcinoma samples from patient samples taken from healthy volunteers, patients with benign biliary obstruction, and patients with other related cancers. In conclusion, lipidomics is a non-invasive method with high sensitivity and specificity for identification of extrahepatic cholangiocarcinoma in patients with biliary obstruction. PMID:27644677

    The management of jaundice and cholangitis is important for improving the prognosis and quality of life of patients with unresectable malignant hilar biliary strictures(UMHBS). In addition, effective chemotherapy, such as a combination of gemcitabine and cisplatin, requires the successful control of jaundice and cholangitis. However, endoscopic drainage for UMHBS is technical demanding, and continuing controversies exist in the selection of the most appropriate devices and techniques for stent deployment. Although metallic stents(MS) are superior to the usual plastic stents in terms of patency, an extensive comparison between MS and "inside stents", which are deployed above the sphincter of Oddi, is necessary. Which techniques are preferred remains as yet unresolved: for instance, whether to use a unilateral or bilateral drainage, or a stent-in-stent or side-by-side method for the deployment of bilateral MS, although a new cell design and thin delivery system for MS allowed us to accomplish successful deployments of bilateral MS. The development of techniques and devices for re-intervention after stent occlusion is also imperative. Further critical investigations of more effective devices and techniques, and increased randomized controlled trials are warranted to resolve these important issues.

    The patient was a 69 year old man who had been diagnosed with alcoholic chronic pancreatitis and lower common bile duct (CBD) stricture. He subsequently developed cholangitis 2-3 times a year, and we replaced the endoscopic biliary stent (EBS) each time. In April 2010, he was admitted because of complication by a liver abscess and acute cholangitis. We performed percutaneous transhepatic liver abscess drainage. The inflammatory findings then rapidly improved, but the patient developed acute cholangitis due to the sludge and the stones. Then, we placed a partially covered self-expandable metallic stent (C-SEMS) in the lower CBD and performed endoscopic lithotripsy through the C-SEMS, and the cholangitis subsequently improved. Two weeks after, we removed the C-SEMS endoscopically and replaced it with a 10 Fr plastic stent; since then there have been no recurrences of cholangitis. Our experience in this case suggested that when a plastic stent is placed long-term to treat a biliary stricture associated with chronic pancreatitis, it might be useful to also control biliary sludge and stones using a C-SEMS.

    Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is an autosomal recessive lysosomal storage disorder resulting from a deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS) activity. Diagnosis can be challenging and requires agreement of clinical, radiographic, and laboratory findings. A group of biochemical genetics laboratory directors and clinicians involved in the diagnosis of MPS IVA, convened by BioMarin Pharmaceutical Inc., met to develop recommendations for diagnosis. The following conclusions were reached. Due to the wide variation and subtleties of radiographic findings, imaging of multiple body regions is recommended. Urinary glycosaminoglycan analysis is particularly problematic for MPS IVA and it is strongly recommended to proceed to enzyme activity testing even if urine appears normal when there is clinical suspicion of MPS IVA. Enzyme activity testing of GALNS is essential in diagnosing MPS IVA. Additional analyses to confirm sample integrity and rule out MPS IVB, multiple sulfatase deficiency, and mucolipidoses types II/III are critical as part of enzyme activity testing. Leukocytes or cultured dermal fibroblasts are strongly recommended for enzyme activity testing to confirm screening results. Molecular testing may also be used to confirm the diagnosis in many patients. However, two known or probable causative mutations may not be identified in all cases of MPS IVA. A diagnostic testing algorithm is presented which attempts to streamline this complex testing process.

    Liver transplantation (LT) is the only definitive treatment for patients with end-stage liver disease due to primary sclerosing cholangitis (PSC), but a high rate of biliary strictures (BSs) and of recurrent primary sclerosing cholangitis (recPSC) has been reported. In this multicenter study, we analyzed a large patient cohort with a long follow-up in order to evaluate the incidence of BS and recPSC, to assess the impact on survival after LT, and to identify risk factors. We collected clinical, surgical, and laboratory data and records on inflammatory bowel disease (IBD), immunosuppression, recipient and graft outcome, and biliary complications (based on cholangiography and histology) of all patients who underwent LT for PSC in 10 German transplant centers between January 1990 and December 2006; 335 patients (68.4% men; mean age, 38.9 years; 73.5% with IBD) underwent transplantation 8.8 years after PSC diagnosis with follow-up for 98.8 months. The 1-, 5-, and 10-year recipient and graft survival was 90.7%, 84.8%, 79.4% and 79.1%, 69.0%, 62.4%, respectively. BS was diagnosed in 36.1% after a mean time of 3.9 years, and recPSC was diagnosed in 20.3% after 4.6 years. Both entities had a significant impact on longterm graft and recipient survival. Independent risk factors for BS were donor age, ulcerative colitis, chronic ductopenic rejection, bilirubin, and international normalized ratio (INR) at LT. Independent risk factors for recPSC were donor age, IBD, and INR at LT. These variables were able to categorize patients into risk groups for BS and recPSC. In conclusion, BS and recPSC affect longterm graft and patient survival after LT for PSC. Donor age, IBD, and INR at LT are independent risk factors for BS and recPSC and allow for risk estimation depending on the recipient-donor constellation.

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

    1985-05-01

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

  20. Primary Biliary Cirrhosis Is a Generalized Autoimmune Epithelitis

    Directory of Open Access Journals (Sweden)

    Jun Gao

    2015-03-01

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

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

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

    The bile was collected from fro patients with biliary infections, with the bacterium isolated to study the sensitivity of each kind of the bacterium to several antibiotics in common use. Except G- bacterium, we also found some kinds of G+ bacterium in infection bile. G- bacterium were not sensitive to Clindamycin, G+ bacterium were sensitive to Ciprofloxacin. Escherichia coli,Xanthomonas maltophilia, Enterobacter cloacae, Pseudomonas aeruginosa were sensitive to Ampicillin. G+ bacterium were not sensitive to Azactam. Enterococcus faecalis, Enterococcus faecium,Enterobacter cloacae were not sensitive to Ceftazidime. Enterococcus faecalis, Staphylococcus coagulase negative, Staphylococcus epidermidis, Pseudomonas aeruginosa were not sensitive to Ceftriaxone Sodium. We didn't found any bacterium resistance Imipenem. The possibility of the existence of G+ bacterium as well as drug resistance should be considered n patients with biliary infections.The value of susceptibility test should be respected to avoid drug abuse of antibiotics.

  5. Interventional radiology of malignant biliary obstruction complication and treatment

    International Nuclear Information System (INIS)

    Intervetional therapy as an important therapeutic method for malignant biliary obstruction has been used extensively, but there still remain some problems worthy for our emphasis and research. We retrospectively reviewed more than 800 patients with malignant obstructive jaundice during 12 years. Indications, contraindications, complications and corresponding treatment methods were studied. Furthermore, discussion including methods of biliary drainage, proper time of stent implantation, methods of anesthesia, usage of antibiotics and haemostat were also carded out. Use of analgesics (pain-suppressal) pre- and post procedure, development of acute pancreatitis and its management, and peri-operative mortality were further investigated in detail. We hope our experiences and lessons would give interventional doctors some help in their career. (authors)

    1979-08-01

    Forty patients who underwent biliary surgery were investigated for postoperative pancreatic disturbance as measured by the amylase creatinine clearance ration (ACCR). Its relevance to preoperative pancreatitis, exploration of the common bile duct, and operative cholangiography were examined. The results suggested that a recent clinically proven episode of pancreatitis did not predispose to a postoperative recurrence following biliary surgery. Similarly, cholecystectomy alone did not produce a postoperative pancreatic disturbance. However, exploration of the common bile duct did frequently cause a postoperative elevated ACCR, and hence we recommend that duct exploration should be performed as carefully and as atraumatically as possible. The small number of patients who did not have operative cholangiograms prevented statistical evaluation of the effect of this procedure on the pancreas. However, information from elsewhere suggests that the plasma amylase level is not likely to be raised by cholangiography. PMID:291412

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

    1985-03-01

    The evaluation of symptomatic patients who have undergone biliary enteric anastomoses, particularly when the diversion was into the jejunum, is difficult. Conventional techniques for evaluation, such as oral cholecystography (OCG), intravenous cholangiography (IVC), ultrasonography (US), computer-assisted tomography scanning (CT scanning), or endoscopy are not adequate to provide definitive information on the patency of the anastomoses. Hepatobiliary scintiscanning using /sup 99m/Tc-HIDA and BIDA (iminodiacetic acid derivatives) was performed on 12 patients. The patients were from 11 to 72 years of age and included ten men and two women. The scan results were correlated with US, CT scan, percutaneous transhepatic cholangiography (PTC), operative findings, and final diagnosis. Scanning was highly accurate in this group and could be performed successfully even in jaundiced patients (total serum bilirubin level up to 20.0 mg/dl). In patients in whom dilated bile ducts were demonstrated (by US, CT scan, or scintiscan), only the scintiscan revealed the true patency of the anastomoses. The advantages of the technique are that it is simple and noninvasive. Delayed transit of bile (scanning agent) to bowel is a very reliable indication of partial or complete obstruction. Scintiscanning is the only technique that demonstrated the functional state of biliary secretion and excretion into bowel in patients with previous biliary enteric anastomoses.

    International Nuclear Information System (INIS)

    Objective: To investigate the role of interventional procedures in the management of biliary tract complications following liver transplantation, and so as the effect of t-tube indwelling. Methods: A review was made of data collected from 55 patients in two groups designated according to t-tube indwelling (28)or not (27). Data were retrospectively analyzed in terms of interventional procedures performed, and outcomes. Results: A total of 55 liver transplantation patients survived more than 1 month after interventional treatment for biliary tract complications, including 11 only with a drainage T-tube, the other 44 (80.0%) with one or more interventional procedures such as PTBD, balloon dilation to cure obstructive jaundice. Additionally 8 cases undertook stenting for hepatic artery, hepatic vein or portal vein stenosis. Conclusions: Interventional procedures are safe and effective for most patients with biliary tract complications following liver transplantation, with easy repetition in performance, including T-tube indwelling to provide a route for further diagnosis and treatment. Yet it is necessary to have other various interventional managements for the whole intact satisfaction of patients. (authors)

  4. Photodynamic therapy for pancreatic and biliary tract carcinoma

    Pereira, Stephen P.

    2009-02-01

    Patients with non-resectable pancreatic and biliary tract cancer (cholangiocarcinoma and gallbladder cancer) have a dismal outlook with conventional palliative therapies, with a median survival of 3-9 months and a 5 year survival of less than 3%. Surgery is the only curative treatment but is appropriate in less than 20% of cases, and even then is associated with a 5-year survival of less than 30%. Although most applications of photodynamic therapy (PDT) in gastroenterology have been on lesions of the luminal gut, there is increasing experimental and clinical evidence for its efficacy in cancers of the pancreas and biliary tract. Our group has carried out the only clinical study of PDT in pancreatic carcinoma reported to date, and showed that PDT is feasible for local debulking of pancreatic cancer. PDT has also been used with palliative intent in patients with unresectable cholangiocarcinoma, with patients treated with stenting plus PDT reporting improvements in cholestasis, quality of life and survival compared with historical or randomized controls treated with stenting alone. Further controlled studies are needed to establish the influence of PDT and chemotherapy on the survival and quality of life of patients with pancreatic and biliary tract carcinoma.

  5. Intraluminal radiation therapy in the management of malignant biliary obstruction

    International Nuclear Information System (INIS)

    Fifteen patients with malignant biliary obstruction from carcinoma of the bile ducts, gallbladder, and pancreas (Group I) or metastatic disease (Group II) were treated with intraluminal radiation therapy (ILRT) at Memorial Sloan-Kettering Cancer Center. In 11 cases ILRT was used as a central boost in combination with 3000 cGy external beam radiation therapy (ERT). No significant treatment toxicity was observed. Cholangiographic response was observed in 2 of 12 evaluable patients. In no patient was long-term relief of jaundice without indwelling biliary stent achieved. Survival from treatment in eight Group I patients treated with ILRT +/- ERT was 3 to 13 months (median, 4.5). Survival in seven similarly treated Group II patients was 0.5 to 8 months (median, 4.0). Additional data for ten similar patients referred for ILRT but treated with ERT alone are presented. Analysis of this and other reports indicate the need for prospective controlled trials of the role of this regimen in the management of malignant biliary obstruction before wider application can be recommended

    AIM: To study the correlation between liver fibrosis severity and biliary drainage in patients with choledocholith.METHODS: A follow-up study on seven patients with liver fibrosis due to choledocholith was made. The data, including biochemical tests (aspartate aminotransferase, alanine aminotransferase) and liver histological features before and after biliary drainage, were collected and studied. The fibrosis severity was scored on a scale from 0 to 3, with 0 denoting none, 1 portal and periportal fibrosis, 2 the presence of numerous fiber septa, and 3 cirrhosis. The average liver fibrosis severity scores of the first and second biopsy were compared with statistical method.RESULTS: The first, second liver fibrosis severity scores of these seven patients were 2,1; 2,1; 1,0; 1,1; 2,1; 2,1;1,0 respectively. The results showed that the average liver fibrosis severity score of the second liver biopsy decreased significantly compared with the first liver biopsy (n = 7, t = 4.25, P<0.05).CONCLUSION: Liver fibrosis due to choledocholith may regress after biliary drainage.

    Primary biliary cirrhosis (PBC) is a disease of unknown etiology leading to progressive destruction of small intrahepatic bile ducts and eventually to liver cirrhosis and failure. It is characterised by female predominance and serum auto-antibodies to mitochondrial antigens targeting the E2 components of the 2-oxoacid dehydrogenase complex. Although they are associated with disease pathogenesis, no concrete evidence has been presented so far. Epidemiological data indicate that a geographical clustering of cases and possible environmental factors are implicated in pathogenesis. A number of genetic factors play a role in determining disease susceptibility or progression, although no definitive conclusion has been reached so far. A key factor to immune pathogenesis is considered to be the breakdown of immune tolerance, either through molecular mimicry or through the so called determinant density model. Tn this review, the available data regarding the pathogenesis of primary biliary cirrhosis are described and discussed. A new unifying hypothesis based on early endothelin overproduction in primary biliary cirrhosis (PBC) is presented and discussed.

    Full Text Available Complications of the biliary tract like bile leaks, strictures are an important cause of morbidity and mortality after liver transplantation. The frequency of such complications ranges from 5 to 25%. In most cases, biliary complications can be treated by endoscopy and/or methods of interventional radiology. This article is about the clinical case of liver transplantation with duct-to-duct biliary reconstruction, complicated by bile leaks, biliary tract stricture. Surgical correction of complications was ineffective. We used miniinvasive methods and got po- sitive clinical outcome after radiology intervention for prosthetics of the common bile duct.

    Biliary complications are significant causes of morbidity and mortality after orthotopic liver transplantation (OLT). The estimated incidence of biliary complications after OLT ranges between 10%-25%, however, these numbers continue to decline due to improvement in surgical techniques. The most common biliary complications are strictures (both anastomotic and non-anastomotic) and bile leaks. Most of these problems can be appropriately managed with endoscopic retrograde colangiography (ERC). Other complications such as bile duct stones, bile casts, sphincter of Oddi dysfunction, and hemobilia, are less frequent and also can be managed with ERC. This article will review the risk factors, diagnosis, and endoscopic management of the most common biliary complications after OLT.

    Endoscopic stenting has become a widely method for the management of various malignant and benign pancreatico-biliary disorders. Biliary and pancreatic stents are devices made of plastic or metal used primarily to establish patency of an obstructed bile or pancreatic duct and may also be used to treat biliary or pancreatic leaks, pancreatic fluid collections and to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis. In this review, relevant literature search and expert opinions have been used to evaluate the outcome of stenting in biliary and pancreatic benign and malignant diseases. PMID:26290631

  11. Treatment of biliary stricture by percutaneous transhepatic insertion of metallic stent

    International Nuclear Information System (INIS)

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

    AIM To assess potential contributions of biliary IgA for crystal agglomeration into gallstones, we visualized cholesterol crystal binding of biliary IgA.METHODS Crystal-binding biliary proteins were extracted from human gallbladder bile using lectin affinity chromatography. Biliary IgA was isolated from the bound protein fraction by immunoaffinity chromatography. Pure cholesterol monohydrate crystals were incubated with biliary IgA and fluoresceine isothiocyanate (FITC)-conjugated anti-lgA at 37C. Samples were examined under polarizing and fluorescence light microscopy with digital image processing.RESULTS Binding of biliary IgA to cholesterol monohydrate crystals could be visualized with FITC-conjugated anti-lgA antibodies. Peak fluorescence occurred at crystal edges and dislocations. Controls without biliary IgA or with biliary IgG showed no significant fluorescence.CONCLUSION Fluorescence light microscopy provided evidence for cholesterol crystal binding of biliary IgA. Cholesterol crystalbinding proteins like IgA might be important mediators of crystal agglomeration and growth of cholesterol gallstones by modifying the evolving crystal structures in vivo.

  15. B cell deficient mice are protected from biliary obstruction in the rotavirus-induced mouse model of biliary atresia.

    Directory of Open Access Journals (Sweden)

    Amy G Feldman

    Full Text Available A leading theory regarding the pathogenesis of biliary atresia (BA is that bile duct injury is initiated by a virus infection, followed by an autoimmune response targeting bile ducts. In experimental models of autoimmune diseases, B cells have been shown to play an important role. The aim of this study was to determine the role of B cells in the development of biliary obstruction in the Rhesus rotavirus (RRV-induced mouse model of BA. Wild-type (WT and B cell-deficient (Ig-α(-/- mice received RRV shortly after birth. Ig-α(-/- RRV-infected mice had significantly increased disease-free survival rate compared to WT RRV-infected BA mice (76.8% vs. 17.5%. In stark contrast to the RRV-infected BA mice, the RRV-infected Ig-α(-/- mice did not have hyperbilirubinemia or bile duct obstruction. The RRV-infected Ig-α(-/- mice had significantly less liver inflammation and Th1 cytokine production compared to RRV-infected WT mice. In addition, Ig-α(-/- mice had significantly increased numbers of regulatory T cells (Tregs at baseline and after RRV infection compared to WT mice. However, depletion of Tregs in Ig-α(-/- mice did not induce biliary obstruction, indicating that the expanded Tregs in the Ig-α(-/- mice were not the sole reason for protection from disease. Conclusion : B cell deficient Ig-α(-/- mice are protected from biliary obstruction in the RRV-induced mouse model of BA, indicating a primary role of B cells in mediating disease pathology. The mechanism of protection may involve lack of B cell antigen presentation, which impairs T-cell activation and Th1 inflammation. Immune modulators that inhibit B cell function may be a new strategy for treatment of BA.

    We investigated the ability of curcumin, which can be extracted from different Curcuma species, to prevent cyclosporin-induced reduction of biliary bilirubin and cholesterol excretion, and its influence on biliary excretion of cyclosporin (CS) and its metabolites in the bile fistula model in rats. I.v. injection of curcumin (25 and 50 mg/kg) after 30 min increased dose-dependently basal bile flow (30 microliters/kg/min) up to 200%, biliary bilirubin excretion (3000 pmol/kg/min) up to 150%, and biliary cholesterol excretion (22 nmol/kg/min) up to 113%. CS (30 mg/kg) reduced bile flow to 66% and biliary excretion of bilirubin and of cholesterol to 33% of the basal value 30 min after i.v. injection. I.v. administration of curcumin (25 and 50 mg/kg) 30 min after CS increased bile flow dose dependently again to 130% for 1 hour and biliary excretion of cholesterol and of bilirubin to 100% of the basal value for 30 and 150 min, respectively. Injection of curcumin 15 min before CS prevented the CS-induced drop of bile flow at 50 mg/kg and reduction of biliary bilirubin excretion already at 25 mg/kg until the end of the experiment (180 min). The CS-induced reduction of biliary cholesterol excretion, however, was not prevented by curcumin. Finally, the biliary excretions of CS (1200 ng/kg/min) and its metabolites (1200 ng/kg/min) were slightly reduced by curcumin at a dose of 50 mg/kg (to 83% of the initial values). The clinical importance of these controversial effects remains to be shown.

    Transplantation of rat hepatocytes into the syngeneic rat spleen results in the appearance of cytokeration (CK)-19-positive biliary cells that form ductules. The exact origin of CK-19-positive cells is not known and the possibility that they are derived from biliary cells or precursors of oval cells in transplanted hepatocyte preparations has been raised. In the present study, we found that the number of CK-19-positive biliary cells increased rapidly after transplantation of hepatocytes, reached the maximum at 4 weeks, and then gradually decreased. However, a Ki-67 labeling index of CK-19-positive biliary cells was low and showed no significant changes throughout the experimental period. In addition, no or few CK-19-positive cells appeared in the spleen after transplantation of nonparenchymal liver cells enriched with biliary cells. These results showed that biliary cells were not the source of CK-19-positive cells in the spleen. Impairment of precursors of oval cells in the liver by administration of 4,4'-diaminodiphenylmethane 24 h before transplantation of hepatocytes did not prevent the appearance of CK-19-positive biliary cells in the spleen. Moreover, transplantation of nonparenchymal cells carrying an increased number of oval cells by means of treatment with 2-acetylaminofluorene and partial hepatectomy resulted in no appearance of CK-19-positive biliary cells in the spleen. These results ruled out oval cells as the origin of CK-19-positive biliary cells in the spleen. Because CK-19-positive biliary cells appeared in the spleen only when hepatocyte fractions were transplanted, we suggest transdifferentiation of heptocytes may be the mechanism by which CK-19-positive biliary cells are generated.

    Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by elevated serum anti-mitochondrial Ab and lymphocyte-mediated bile duct damage. This study was designed to reveal the clonal characteristics of B lymphocyte repertoire in patients with PBC to facilitate better understanding of its pathogenesis and better management of these patients. Using high-throughput sequencing of Ig genes, we analyzed the repertoire of circulating B lymphocytes in 43 patients with PBC, and 34 age- and gender-matched healthy controls. Compared with healthy controls, PBC patients showed 1) a gain of 14 new clones and a loss of 8 clones; 2) a significant clonal expansion and increased relative IgM abundance, which corresponded with the elevated serum IgM level; 3) a significant reduction of clonal diversity and somatic hypermutations in class-switched sequences, which suggested a general immunocompromised status; 4) the reduction of clonal diversity and enhancement of clonal expansion were more obvious at the cirrhotic stage; and 5) treatment with ursodeoxycholic acid could increase the clonal diversity and reduce clonal expansion of the IgM repertoire, with no obvious effect on the somatic hypermutation level. Our data suggest that PBC is a complex autoimmune disease process with evidence of B lymphocyte clonal gains and losses, Ag-dependent ogligoclonal expansion, and a generally compromised immune reserve. This new insight into the pathogenesis of PBC opens up the prospect of studying disease-relevant B cells to better diagnose and treat this devastating disease. PMID:27430717

    Primary biliary cirrhosis (PBC) is usually diagnosed by the presence of characteristic histopathological features of the liver and/or antimitochondrial antibodies (AMA) in the serum traditionally detected by immunofluorescence.Recently, new and more accurate serological assays for the detection of AMA, such as enzyme-linked immunosorbent assay (ELISA), immunoblotting, and enzyme inhibition assay, have been developed. Of these,the enzyme inhibition assay for the detection of antipyruvate dehydrogenase complex (PDC) antibodies offers certain advantages such as objectivity, rapidity,simplicity, and low cost. Since this assay has almost 100% specificity, it may have particular applicability in screening the at-risk segment of the population in developing countries. Moreover, this assay could be also used for monitoring the disease course in PBC. Almost all sera of PBC-suspected patients can be confirmed for PBC or non-PBC by the combination results of immunoblotting and enzyme inhibition assay without histopathological examination. For the development of a "complete" or "gold standard" diagnostic assay for PBC, similar assays of the enzyme inhibition for anti2-oxoglutarate dehydrogenase complex (OGDC) and anti-branched chain oxo-acid dehydrogenase complex (BCOADC) antibodies will be needed in future.

    Full Text Available ABSTRACT : BACKGROUND : Congenital absence of GB is a rare anomaly occurrin g in less than 1 in 1000 population. These patients’ complaints of tho se of more common biliary conditions and routine radiological and biochemical investigat ion makes difficult to diagnose preoperatively and patients undergo unnecessary operat ive intervention. MATERIALS AND METHODS : A 18 years old female with clinical features of Ch olecystitis diagnosed by USG as Contracted GB with Cholelithiasis was operated for O pen Cholecystectomy. Intra-operatively, the GB could not be seen even after thorough dissec tion. Post operative MRCP confirmed the diagnosis of absence of GB. RESULTS: The patient having the classical features of Gall St one disease with the routine investigative reports, had undergone Operation .As the gall bladder was not found , the procedure was terminated and post operative MRCP confirmed the diagnosis of absence of GB. CONCLUSION: The rare congenital anomaly of absence of GB may have common biliary conditions, and so patients may undergo unnecessary operative procedures. With the newer minimally invasive radiol ogic techniques, this situation can largely be avoided if awareness of this condition is improve d.

    This article is part of a combined publication that expresses the current view of the European Society of Gastrointestinal Endoscopy about endoscopic biliary stenting. The present Clinical Guideline describes short-term and long-term results of biliary stenting depending on indications and stent models; it makes recommendations on when, how, and with which stent to perform biliary drainage in most common clinical settings, including in patients with a potentially resectable malignant biliary obstruction and in those who require palliative drainage of common bile duct or hilar strictures. Treatment of benign conditions (strictures related to chronic pancreatitis, liver transplantation, or cholecystectomy, and leaks and failed biliary stone extraction) and management of complications (including stent revision) are also discussed. A two-page executive summary of evidence statements and recommendations is provided. A separate Technology Review describes the models of biliary stents available and the stenting techniques, including advanced techniques such as insertion of multiple plastic stents, drainage of hilar strictures, retrieval of migrated stents and combined stenting in malignant biliary and duodenal obstructions.The target readership for the Clinical Guideline mostly includes digestive endoscopists, gastroenterologists, oncologists, radiologists, internists, and surgeons while the Technology Review should be most useful to endoscopists who perform biliary drainage.

    Everson LA Artifon

    2010-11-01

    Full Text Available Context Endoscopic retrograde cholangiopancreatography (ERCP is the procedure of choice for biliary decompression in patients with unresectable pancreatic cancer. However, it may be unsuccessful in 3 to 10% of cases. When ERCP is unsuccessful, the usual alternatives are percutaneous transhepatic biliary drainage or surgery. Recently, several authors have reported the use of EUS-guided biliary drainage in patients with malignant biliary obstructions, with acceptable success and complication rates. We describe three cases of unresectable pancreatic cancer associated with obstructive jaundice, treated by EUS-guided biliary drainage. Case report Three patients with unresectable pancreatic cancer, associated with obstructive jaundice, were included. ERCP was unsuccessful because of complete tumor obstruction of the distal common bile duct and papilla invasion. An EUS-guided rendezvous maneuver was attempted, without success. Then, EUS-guided choledochoduodenostomy, with a partially covered self-expanding metal stent, was performed in the same procedure. There were no early complications and the procedure was also clinically effective in relieving jaundice in all cases. Conclusions EUS-guided biliary drainage is a feasible alternative to percutaneous transhepatic biliary drainage or surgery in unresectable pancreatic cancer with obstructive jaundice when ERCP fails. However, the development of new specific instruments and studies comparing this procedure with percutaneous transhepatic biliary drainage and surgery are needed.

    Transpapillary stents are increasingly being used for biliary strictures, whether benign or malignant. However, there are different stent types and available data is controversial. Recently, completely covered self-expandable metal stents (CSEMSs) have been proposed as an alternative therapeutic option in different biliary indications, including strictures of the distal bile duct, anastomotic stenosis after orthotopic liver transplantation, bile duct leaks, periampullary perforation following...

  9. Percutaneous placement of biliary stent for treatment of malignant obstructive jaundice

    International Nuclear Information System (INIS)

    Objective: To introduce the techniques of percutaneous biliary stenting and intraarterial embolization for treatment in patients with hepatocellular carcinoma and biliary obstruction accompanying the evaluation of the therapeutic effect. Methods: Percutaneous biliary metallic stent placement and intraarterial embolization were performed in 12 patients with hepatocellular carcinoma and obstructive jaundice, with mean age of 52.3 years old. Results: Fourteen stents and 3 external biliary drainage catheters were placed in 12 patients. One stent for each was inserted in 7 patients with communication between right and left hepatic ducts; right and left biliary drainages were separately performed with stents or external biliary drainage catheters in 5 with no communication. The serum total bilirubin decreased from 405.3 ± 175.4 μmol/L before the procedure to 188.3 ± 101.5 μmol/L one week after the procedure (P<0.01), and both alkaline phosphatase and transaminase decreased significantly (P<0.05). Percutaneous transarterial chemoembolization for treatment of hepatocellular carcinoma was done one to four time with average of 2.1 times after biliary drainage. There were no severe complications related to the interventional procedure. All patients were followed up with an average of 9.5 months, including 5 patients alive. Conclusions: The percutaneous biliary stenting and intraarterial embolization are safe and effective palliative therapies in patients with hepatocellular carcinoma and obstructive jaundice. It can alleviate jaundice and improve the liver function with longer survival rate

    Full Text Available Introduction: Preoperative biliary drainage pre DPC is a very controversial subject; the indication for this endoscopic procedure is not yet unanimous accepted. Material and methods: The aim of this study is to find out if preoperative biliary drainage is bringing benefits to the perioperatory evolution of the patient. This is a prospective study from 2008 till 2010, done in Surgery Clinic no III of Cluj-Napoca. 201 patients with pancreatic cancer on which surgery with biliary anastomosis was performed were included in the study; 41 of them were preoperative biliary drained. Results: Patients who had preoperative biliary drainage had a higher percentage of postoperatory complications (p=0,049. Preoperative biliary drainage determined a non significant longer intraoperative time, blood lost and a not much harder intraoperative conditions. Septic complications were twice more frequent in patients with preoperative biliary drainage; the data were statistically validated (p=0,036. Conclusions: Preoperative biliary drainage must be done in carefully selected cases; the intervention that follows this endoscopic procedure should be performed by specialized surgical teams that can cope with harder intraoperative conditions.

    Symptomatic biliary stricture causes life-threatening complications, such as jaundice, recurrent cholangitis and secondary biliary cirrhosis. Fully covered self-expanding metal stents (FCSEMSs) are gaining acceptance for treatments of benign biliary stricture and palliative management of malignant biliary obstructions. However, the high rate of FCSEMS obstruction limits their clinic use. In this study, we developed a novel biliary stent coated with silver nanoparticles (AgNPs) and investigated its efficacy both in vitro and in vivo. We first identified properties of the AgNP complex using ultraviolet detection. The AgNP complex was stable without AgNP agglomeration, and Ag abundance was correspondingly increased with an increased bilayer number. The AgNP biliary stent demonstrated good performance in the spin-assembly method based on topographic observation. The AgNP biliary stent also exhibited a long-term anti-coagulation effect and a slow process of Ag(+) release. In vitro anti-bacteria experiments indicated that the AgNP biliary stent exhibited high-efficiency anti-bacterial activity for both short- and long-term periods. Importantly, application of the AgNP biliary stent significantly prolonged the unobstructed period of the biliary system and improved survival in preclinical studies as a result of its anti-microbial activity and decreased granular tissue formation on the surface of the anastomotic biliary, providing a novel and effective treatment strategy for symptomatic biliary strictures.

    International Nuclear Information System (INIS)

    Objective: To evaluate the percutaneous transhepatic drainage and biliary stent placement as the treatment of biliary obstruction. Methods: Twenty-three patients with biliary obstruction received percutaneous transhepatic cholangiography and drainage (PTCD). And among the 23, stent placement was performed in 12 patients. Results: All 23 patients jaundice was satisfactorily relieved, and total bilirubin value was decreased from 147.4 pmol/L-648.7 pmol/L, the pre-procedure data, to the post-procedure data at normal level or very close to normal level. In 22 case of malignant biliary obstruction, the survival rate of 3 and 6 months 70% and 60% respectively. the median survival was 6 months. Conclusion: The combination of metallic stent placement and local therapy are effective in the treatment of biliary obstruction which is unable to be cured by surgical procedure. (authors)

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

    Directory of Open Access Journals (Sweden)

    Motoko Sasaki

    2012-01-01

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

  17. Covered Self-Expanding Transhepatic Biliary Stents:Clinical Pilot Study

    International Nuclear Information System (INIS)

    Purpose: We report our preliminary results with a new type of self-expanding covered stent for treatment of malignant biliary obstruction. Methods: Wallstents, fully covered with high elasticity polyurethane, with an unconstrained diameter of 10 mm and a total length of 69 mm, were placed transhepatically under fluoroscopic guidance in five patients. The length of the biliary obstruction varied between 30-50 mm. At 1 and 3 months (82-98 days) clinical assessment, serum bilirubin measurement, and ultrasound examination of the biliary tree were performed. Results: Initial uncomplicated deployment of the stents and internal drainage was possible in all patients. Distal stent migration resulted in early biliary reobstruction in one patient. At 3-month follow-up, partial reobstruction, most probably due to sludge formation, was found in another patient. Conclusion: Our initial results indicate that the covered, self-expanding Wallstent endoprosthesis can be reliably and safely deployed transhepatically for malignant biliary obstruction

  18. Effect of diethyl ether on the biliary excretion of acetaminophen.

    Watkins, J B; Siegers, C P; Klaassen, C D

    1984-10-01

    The biliary and renal excretion of acetaminophen and its metabolites over 8 hr was determined in rats exposed to diethyl ether by inhalation for 1 hr. Additional rats were anesthetized with urethane (1 g/kg ip) while control animals were conscious throughout the experiment (surgery was performed under hexobarbital narcosis: 150 mg/kg ip; 30-min duration). The concentration of UDP-glucuronic acid was decreased 80% in livers from ether-anesthetized rats but was not reduced in urethane-treated animals when compared to that in control rats. The concentration of reduced glutathione was not affected by either urethane or diethyl ether. Basal bile flow was not altered by the anesthetic agents. Bile flow rate after acetaminophen injection (100 mg/kg iv) was increased slightly over basal levels for 2 hr in hexobarbital-treated control rats, was unaltered in urethane-anesthetized animals, and was decreased throughout the 8-hr experiment in rats exposed to diethyl ether for 1 hr. In control and urethane-anesthetized animals, approximately 30-35% of the total acetaminophen dose (100 mg/kg iv) was excreted into bile in 8 hr, while only 16% was excreted in rats anesthetized with diethyl ether. Urinary elimination (60-70% of the dose) was not altered by exposure to ether. Separation of metabolites by reverse-phase high-pressure liquid chromatography showed that ether decreased the biliary elimination of unchanged acetaminophen and its glucuronide, sulfate, and glutathione conjugates by 47, 40, 49, and 73%, respectively, as compared to control rats. Excretion of unchanged acetaminophen and the glutathione conjugate into bile was depressed in urethane-anesthetized animals by 45 and 66%, respectively, whereas elimination of the glucuronide and sulfate conjugates was increased by 27 and 50%, respectively. These results indicate that biliary excretion is influenced by the anesthetic agent and that diethyl ether depresses conjugation with sulfate and glutathione as well as glucuronic

    2016-06-01

    The etiology of primary biliary cirrhosis (PBC) remains unclear, and at present, this disease is considered to be caused by the combined effect of genetic factors, infection, autoimmunity, and environmental factors. Since infection is the major cause for PBC, scholars have been focusing on the association between chronic microbial infection. Studies have shown that Escherichia coli is the most common bacterium for urinary tract infection (UTI), and recurrent UTI has been confirmed to be a risk factor for the development and progression of autoimmune liver diseases and is closely associated with PBC. This article investigates the association between UTI and PBC and possible mechanisms. PMID:27465958

    Laparoscopic cholecystectomy has become the procedure of choice for management of symptomatic cholelithiasis. Although it has distinct advantages over open cholecystectomy, bile leak is more common. Endoscopic retrograde cholangiopancreatography is the diagnostic and therapeutic modality of choice for management of postcholecystectomy bile leaks and has a high success rate with the placement of plastic biliary stents. Repeat endoscopic retrograde cholangiopancreatography with placement of multiple plastic stents, a covered metal stent, or possibly cyanoacrylate therapy may be effective in refractory cases. This review will discuss the indications, efficacy, and complications of endoscopic therapy.

    This report describes the novel sampling of bile from the biliary endoscopic intervention for the molecular identification of parasite infection.A 63-year-old Vietnamese man underwent travel health examination in our hospital. Physical examination showed that his height was 159 cm and weight was 41 kg. He had a 15-year history of intermittent abdominal pain and frequent episodes of diarrhea. Laboratory tests revealed raised eosinophil count (23%, normal range [NR] 0-5), absolute eosinophil count (1899/μL, NR 50-350), and levels of serum immunoglobulin E (3770 IU/mL, NR < 100), aspartate transaminase (270 U/L, NR 0-37), alanine transaminase (210 U/L, NR 0-40), and total bilirubin (1.8 mg/dL, NR 0.2-1.4); however, the serum alkaline phosphatase level was normal (65 U/L, NR 28-94) and non-reactive result for serum human insufficiency virus antibody.Magnetic resonance cholangiopancreatography revealed diffuse dilatation of the biliary tree; the common hepatic and pancreatic duct diameters increased to 1.86 cm and 0.61 cm, respectively.Endoscopic retrograde cholangiopancreatography was performed and a 10-Fr model plastic biliary stent was inserted and flushed with 20 cc normal saline; thereafter, the bile was collected and sent for DNA sequencing. Isospora belli (IB) infection was identified by a polymerase chain reaction.Trimethoprim-sulfamethoxazole 800 mg q6h was administered for 1 month. Liver enzyme levels normalized and negative for concentration method of ova study. The patient was doing well and weighed 51 kg at the outpatient clinic visit 3 months later.This bile sampling with molecular identification has not been described in the literature. We believe that an acute IB infection through fecal-oral transmission may progress to chronic infection of the hepatobiliary system, leading to biliary obstruction and jaundice. PMID:26962840

    International Nuclear Information System (INIS)

    Biliary endoprosthesis, including plastic stents and metallic stents, have been widely used in the management of various benign or malignant bile duct stenosis. Although the short-term effect is most satisfactory, the long-term result is unsatisfactory because of the displacement and restenosis of the stent. Metallic stent is superior to plastic stent in keeping the stent open for long time and the technique has been improved gradually. This paper aims to make a review of the related literatures and to summarize the recent progress in the applied research. (authors)

    There are many studies about the biliary stents, however there is a little information about the long-term stayed forgotten biliary stents except a few case reports. We have reported the results of a number of cases with biliary stents that were forgotten or omitted by the patient and the endoscopist. During February 2010 to May 2013, five patients were referred to the general surgery clinic of Haydarpasa Numune Training and Research Hospital, Istanbul Turkey. Past history and medical documents submitted by the patient did not indicate a replacement of the biliary stent in 3 patients. Two patients knew that they had biliary stents. We also conducted a literature review via the PubMed and Google Scholar databases of English language studies published until March 2014 on forgotten biliary stent. There were 3 men and 2 women ranging in age from 22 to 68 years (mean age 41.6 years). Patients presented with pain in the upper abdomen, jaundice, fever, abnormal liver function tests or dilatation of the biliary tract alone or in combination. Patients’ demographic findings are presented in Table 1. A review of three cases reported in the English medical literature also discussed. The mean duration of the patency of the stent is about 12 months. The biliary stenting is performed either with plastic or metal stents, studies recommending their replacement after 3-6 months. Patients with long stayed forgotten biliary stents are inevitably treated with surgical intervention. We recommend for all endoscopic retrograde cholangiopancreatography units provide a stent registry system that the stents placed for various therapeutic procedures are not forgotten both by the patient as well as the physician. There should be a deadline for biliary stents in the registry system for each patient. PMID:25232385

    2016-01-28

    Despite advances in surgical techniques, benign biliary strictures after living donor liver transplantation (LDLT) remain a significant biliary complication and play an important role in graft and patient survival. Benign biliary strictures after transplantation are classified into anastomotic or non-anastomotic strictures. These two types differ in presentation, outcome, and response to therapy. The leading causes of biliary strictures include impaired blood supply, technical errors during surgery, and biliary anomalies. Because patients usually have non-specific symptoms, a high index of suspicion should be maintained. Magnetic resonance cholangiography has gained widespread acceptance as a reliable noninvasive tool for detecting biliary complications. Endoscopy has played an increasingly prominent role in the diagnosis and treatment of biliary strictures after LDLT. Endoscopic management in LDLT recipients may be more challenging than in deceased donor liver transplantation patients because of the complex nature of the duct-to-duct reconstruction. Repeated aggressive endoscopic treatment with dilation and the placement of multiple plastic stents is considered the first-line treatment for biliary strictures. Percutaneous and surgical treatments are now reserved for patients for whom endoscopic management fails and for those with multiple, inaccessible intrahepatic strictures or Roux-en-Y anastomoses. Recent advances in enteroscopy enable treatment, even in these latter cases. Direct cholangioscopy, another advanced form of endoscopy, allows direct visualization of the inner wall of the biliary tree and is expected to facilitate stenting or stone extraction. Rendezvous techniques can be a good option when the endoscopic approach to the biliary stricture is unfeasible. These developments have resulted in almost all patients being managed by the endoscopic approach. PMID:26819525

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

  16. Percutaneous Management of Biliary Strictures After Pediatric Liver Transplantation

    International Nuclear Information System (INIS)

    We analyze our experience with the management of biliary strictures (BSs) in 27 pediatric patients who underwent liver transplantation with the diagnosis of BS. Mean recipient age was 38 months (range, 2.5-182 months). In all patients percutaneous transhepatic cholangiography, biliary catheter placement, and bilioplasty were performed. In 20 patients the stenoses were judged resolved by percutaneous balloon dilatation and the catheters removed. Mean number of balloon dilatations performed was 4.1 (range, 3-6). No major complications occurred. All 20 patients are symptom-free with respect to BS at a mean follow-up of 13 months (range, 2-46 months). In 15 of 20 patients (75%) one course of percutaneous stenting and bilioplasty was performed, with no evidence of recurrence of BS at a mean follow-up of 15 months (range, 2-46 months). In 4 of 20 patients (20%) two courses of percutaneous stenting and bilioplasty were performed; the mean time to recurrence was 9.8 months (range, 2.4-24 months). There was no evidence of recurrence of BS at a mean follow-up of 12 months (range, 2-16 months). In 1 of 20 patients (5%) three courses of percutaneous stenting and bilioplasty were performed; there was no evidence of recurrence of BS at a mean follow-up of 10 months. In conclusion, BS is a major problem following pediatric liver transplantation. Radiological percutaneous treatment is safe and effective, avoiding, in most cases, surgical revision of the anastomosis.

    99mTc-diethyl-IDA is completely excreted into the bile. When cholecystokinin is given after priming of the biliary tract with this tracer, gallbladder contraction leads to expulsion of bile into the duodenum. At the same time cholecystokinin causes contraction of the pylorus, which should normally prevent substantial reflux of tracer into the stomach. We have applied these physiological characteristics in a method to quantify biliary gastric reflux. Fourteen controls had a median reflux of 4.3% of the intravenous dose (93% of controls had values less than 9%). In 18 patients with Billroth II gastrectomies the median reflux was 46% (p less than 0.001). Patients with chronic gastritis (no. = 18) had also increased reflux (median 18.1%, p less than 0.001). The same was found in gastric ulcer (no. = 18, median 11.8%, p less than 0.003). In duodenal ulcer (no. = 7) increased reflux existed in only two patients with pyloric deformation. Patients with hiatal hernia did not show increased reflux (no. = 10, median 2.2%). Bilirubin measurements tended to underestimate reflux in pathological cases, whereas bile acid measurements and reflux percentages of tracer showed a close relationship (r = 0.87, p less than 0.001).

    Biliary tract cancers (BTCs) are a group of highly aggressive malignant tumors with a poor prognosis. The current diagnosis is based mainly on imaging and intraoperative exploration due to brush cytology havinga low sensitivity and the standard markers, such as carcinoembryonic antigen (CEA) and carbohydrate 19-9 (CA19-9), not having enough sensitivity nor specificity to be used in a differential diagnosis and early stage detection. Thus, better non-invasive methods that can distinguish between normal and pathological tissue are needed. MicroRNAs (miRNAs) are small, single-stranded non-coding RNA molecules of ~20–22 nucleotides that regulate relevant physiological mechanisms and can also be involved in carcinogenesis. Recent studies have demonstrated that miRNAs are detectable in multiple body fluids, showing great stability, either free or trapped in circulating microvesicles, such as exosomes. miRNAs are ideal biomarkers that may be used in screening and prognosis in biliary tract cancers, aiding also in the clinical decisions at different stages of cancer treatment. This review highlights the progress in the analysis of circulating miRNAs in serum, plasma and bile as potential diagnostic and prognostic markers of BTCs. PMID:27223281

    The purpose of this study was to report the magnetic resonance imaging (MRI) features of multiple biliary hamartoma (MBH) and to correlate them with histopathology. MRI features of 11 patients with MBH proven by histology were retrospectively reviewed and correlated to histopathology. MBH presented as multiple, tiny, and uniformly distributed lesions in all cases. All were hypointense on T1-weighted images and hyperintense on T2-weighted images relative to the liver parenchyma. Mural nodules were identified in 10 of 11 (91%) cases. They were isosignal on T1-weighted images, intermediate signal on T2-weighted images. Gadolinium-enhanced images showed mural nodule enhancement in 9 of 10 patients (90%) or a peripheral rim-like enhancement of the whole lesion in one case (9%). MBH were present in all liver specimens. In the six patients examined at MR cholangiography, the lesions lacked communication with the biliary tree. At histopathology, the mural nodule corresponded to an endocystic polypoid projection made of conjunctive septa. Three (27%) patients had associated focal nodular hyperplasia, and 1 (9%) had concomitant cholangiocarcinoma. MRI features allowed diagnosis of MBH with accuracy. Their recognition, especially the mural nodule, may help avoid misdiagnosis. (orig.)

    A case of heterotopic gastric mucosa in the common bile duct, cystic duct and gallbladder is reported in a 3-year-old girl with abdominal pain and jaundice. Abdominal US and CT showed dilatation of the biliary tree and a well-defined mass in the common bile duct that narrowed its lumen. The gallbladder was contracted in both examinations. The common bile duct and the gallbladder were resected and a choledochojejunostomy was performed. Although gastric heterotopy has been described throughout the entire length of the gastrointestinal tract, it is a very uncommon finding in the gallbladder and extremely rare in the biliary tree. A firm diagnosis of gastric heterotopia is based on the presence of fundal mucosa replete with parietal and chief cells. To our knowledge, this is the fifth reported case of heterotopic gastric tissue within the common bile duct, and the first to describe the US and CT findings. A relevant literature review and brief outline of the histological and radiological features are included in the discussion. (orig.)

    AIM: To present our experience using intravenous sedoanalgesia for percutaneous biliary drainage. MATERIALS AND METHODS: This study comprised 100 patients, all of whom were continuously monitored [electrocardiogram (ECG), blood pressure, pulse oxymetry] and received an initial dose of 2 mg midazolam followed by 0.02 mg fentanyl. Before every anticipated painful procedure, a maintenance dose of 0.01 mg fentanyl was administered. If the procedure continued and the patient became aware, another 1 mg midazolam was given. This was repeated if patients felt pain. A total dose of 0.08 mg fentanyl and 7 mg midazolam was never exceeded. Immediately after the procedure, the nurse was asked to evaluate patients' pain score. The patients were asked 3 h later to complete a visual 10-degree pain score scale. RESULTS: The average dose of fentanyl and midazolam was 0.042 mg (0.03-0.08 mg) and 4.28 mg (2-7 mg), respectively. Only one patient recorded the procedure as painful. The scores given by the attending nurse (1-7 points, mean 2.9) correlated well with those given by the patients (1-6 points, mean 2.72). No complications were noted. CONCLUSION: According to our experience, interventional radiologists practising biliary procedures can administer low doses of midazolam and minimize the doses of fentanyl, without loss of adequate sedation and analgesia.

    2008-01-01

    AIM: To evaluate the efficacy of endoscopic treatment in patients who undergo OLTx or LRLTx and develop biliary complications. METHODS: This is a prospective, observational study of patients who developed biliary complications, after OLTx and LRLTx, with duct-to-duct anastomosis p erformed between June 2003 and June 2007. Endoscopic Retrograde Cholangiopancreatography (ERCP) was considered unsuccessful when there was evidence of continuous bile leakage despite endoscopic stent placement, or persistence of stenosis after 1 year, despite multiple dilatation and stent placement. When the ERCP failed, a percutaneous trans-hepatic approach (PTC) or surgery was adopted. RESULTS: From .lune 2003 to .lune 2007, 261 adult patients were transplanted in our institute, 68 from living donors and 193 from cadaveric donors. In the OLTx group the rate of complications was 37.3%, while in the LRLTx group was 64.7%. The rate of FRCP failure was 19.4% in the OLTx group and 38.6% in LRLTx group. In OLTx group, 1 patient was re- transplanted and 8 patients died. In the LRLTx group, 2 patients underwent OLTx and 8 patients died. The follow-up was 23.3 + 13.13 mo and 21.02:1:14.10 raG, respectively. CONCLUSION: Albhough ERCP is quite an effective mode of managing post-transplant bile duct complications, a significant number of patients need other types of approach. Further prospective studies are necessary in order to establish whether other endoscopic protocols or new devices, could improve the current results.

  3. Infectious Agents in the Pathogenesis of Primary Biliary Cirrhosis

    Directory of Open Access Journals (Sweden)

    Oscar-Danilo Ortega-Hernandez

    2010-01-01

    Full Text Available Primary biliary cirrhosis (PBC is a chronic progressive cholestatic liver disease which is characterized by the breakdown of self-tolerance to the highly conserved pyruvate dehydrogenase complex, specially the pyruvate dehydrogenase E2 complex (PDC-E2. The breakdown of the tolerance to such antigens leads to an autoimmune process characterized by portal inflammation and immune-mediated destruction of the intrahepatic bile ducts. Epidemiological studies have suggested that infections agents can trigger or even exacerbate the disease. Among other gram negative bacteria, Escherichia Coli, and Nosphingobium aromaticivorans are the most associated agents reported hitherto. Epidemiological and molecular evidence points towards molecular mimicry between some components of these microorganisms and specific amino-acid sequences that are present in proteins on normal cells of the biliary tract. In this review, we revisit all reports suggesting that infectious agents might be associated with the autoimmune pathogenesis of PBC. We also retrieve the immune molecular mimicry mechanisms that are likely involved with the autoimmune process in PBC.

    Self-expandable metal stents (SEMS) are widely used for the palliative treatment of unresectable malignant biliary obstruction. However, the long-term durability of SEMSs in biliary strictures is not clear. We describe a case of endoscopic removal of spontaneously fractured uncovered biliary SEMS. A 59-year-old woman presented to our institution with a 1-year history of recurrent cholangitis. Her medical history included a proctectomy for rectal cancer and right hemihepatectomy for liver metastasis 10 years earlier. Five years after these operations, she developed a benign hilar stricture and had an uncovered SEMS placed in another hospital. Endoscopic retrograde cholangiopancreatography demonstrated that the SEMS was torn in half and the distal part of the stent was floating in the dilated common bile duct. The papillary orifice was dilated by endoscopic papillary large balloon dilation (EPLBD) using a 15-mm wire-guided balloon catheter. Subsequently, we inserted biopsy forceps into the bile duct and grasped the distal end of the broken SEMS under fluoroscopy. We successfully removed the fragment of the SEMS from the bile duct, along with the endoscope. The patient was discharged without complications. Placement of an uncovered biliary SEMS is not the preferred treatment for benign biliary strictures. Spontaneous fracture of an uncovered biliary SEMS is an extremely rare complication. We should be aware that stent fracture can occur when placing uncovered biliary SEMSs in patients with a long life expectancy. EPLBD is very useful for retrieving the fractured fragment of SEMS.

    International Nuclear Information System (INIS)

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

    Background/Aims The covered self-expandable metal stent (CMS) was developed to prevent tumor ingrowth-induced stent occlusion during the treatment of malignant biliary obstruction. However, complications such as cholecystitis, pancreatitis, and stent migration can occur after the endoscopic insertion of CMSs. The aim of the present study was to assess the efficacy and safety of a double-layered CMS (DCMS) for the management of malignant bile duct obstruction. Methods DCMSs were endoscopically introduced into 59 patients with unresectable malignant extrahepatic biliary obstruction at four tertiary referral centers, and the patient medical records were retrospectively reviewed. Results Both the technical and functional success rates were 100%. Procedure-related complications including pancreatitis, cholangitis, stent migration, and liver abscess occurred in five patients (8.5%). The median follow-up period was 265 days (range, 31 to 752 days). Cumulative stent patency rates were 68.2% and 40.8% at 6 and 12 months, respectively. At the final follow-up, the rate of stent occlusion was 33.9% (20/59), and the median stent patency period was 276 days (range, 2 to 706 days). Conclusions The clinical outcomes of DCMSs were comparable to the outcomes previously reported for CMSs with respect to stent patency period and complication rates. PMID:27172927

    Full Text Available This study aimed to identify nursing diagnoses in overweight adolescents from public schools, according to the International Classification for Nursing Practice. A population-based cross-sectional study that investigated the socio-demographic, behavioural and psychological characteristics of adolescents aged from 10 to 14 years. 11 nursing diagnoses were identified: "Risk of overweight", "Risk of impaired adolescent development", "Risk of insecurity in parental role performance", "Risk of the family impaired ability to manage diet regime", "Risk of impaired ability to manage diet regime", "Risk of lack of knowledge of dietary regime", "Risk of excess food intake", "Risk of negative self-image", "Risk of low self-esteem", "Risk of impaired social well-being" and "Impaired exercise pattern". These diagnoses reflect the multifactorial nature of obesity, highlighting the need for interdisciplinary and intersectoral articulation of nursing interventions for prevention and control of overweight.

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

  11. Intimal hyperplasia within biliary Wallstents: failure of recanalisation by insertion of a second endoprosthesis

    International Nuclear Information System (INIS)

    We report two patients with benign biliary strictures in whom we attempted recanalisation of metallic biliary endoprostheses, occluded by intimal hyperplasia, by the insertion of further endoprostheses within the occluded stents. Initial technical success was achieved in deploying the stents and restoring patency with elimination of mural filling defects. However, we found the intimal hyperplasia to be restrained for less than 48 h. From our initial results it appears that biliary metallic stent occlusion by intimal hyperplasia is not effectively treated by insertion of a second endoprosthesis. (orig.)

  12. Fully Covered Self-Expandable Metal Stents for Treatment of Both Benign and Malignant Biliary Disorders

    Directory of Open Access Journals (Sweden)

    Ahmed Abdel Samie

    2012-01-01

    Full Text Available Transpapillary stents are increasingly being used for biliary strictures, whether benign or malignant. However, there are different stent types and available data is controversial. Recently, completely covered self-expandable metal stents (CSEMSs have been proposed as an alternative therapeutic option in different biliary indications, including strictures of the distal bile duct, anastomotic stenosis after orthotopic liver transplantation, bile duct leaks, periampullary perforation following endoscopic sphincterotomy (ES, and postsphincterotomy bleeding. Despite the higher costs of these devices, fully covered self-expanding metal stents seem to be a suitable therapeutic option to relief biliary obstruction due to bile duct stenosis, regardless of the underlying cause.

  13. Tuberculous biliary strictures: uncommon cause of obstructive jaundice

    International Nuclear Information System (INIS)

    Tuberculous biliary stricture is a very rare cause of obstructive jaundice. A case of a man who had had pulmonary tuberculosis 20 years ago is reported. He now presented with obstructive jaundice due to multiple strictures just below the confluence of the hepatic ducts and in the right hepatic duct. At surgery, these turned out to be tuberculous in origin. There was also tuberculous involvement of the gall bladder and cystic duct. The commonest differential diagnosis in such cases is cholangiocarcinoma (as in the present case). Imaging helps in defining the extent of bile duct obstruction. Suspicion of the disease and establishing a tissue diagnosis is very important in treating this potentially curable condition, especially with the worldwide resurgence of tuberculosis. Imaging modalities such as US and CT may be useful in demonstrating the dilated bile ducts. As there are no specific radiological features of tuberculous biliary strictures, the radiologist should search for any associated findings in abdominal imaging, especially focal hepatic lesions, abdominal lymphadenopathy and abdominal calcification. Tuberculous hepatic involvement can have miliary, nodular and solitary abscess forms. Solitary tuberculous abscesses may be readily detected by sectional imaging such as US, CT or MRI. Ultrasound appearances encountered include well-defined hypoechoic lesions, mixed hyper/hypoechoic masses or almost solid masses. On CT, tuberculous liver abscesses have been described as having a rosette appearance or being a hypodense mass. Magnetic resonance imaging of a tuberculous solitary mass has been described as hypointense on T1-weighted images and iso- or hypointense on T2-weighted images. However, none of these findings are specific or diagnostic of tuberculous origin and, therefore, the lesions have to be sampled percutaneously to arrive at the correct diagnosis. Abdominal lymphadenopathy (mainly periductal, hepatoduodenal ligament and at the porta hepatis) can be

    2012-01-01

    A 6-year-old female nulliparous Dutch Rabbit (Oryctolagus cuniculus) was presented in shock status with a history of abdominal distention, inappetance, lethargy, polydipsia, diarrhea and weight loss since 2 weeks ago. There was no breeding history. Radiographic survey showed increased soft tissue opacity dorsal to the urinary bladder and ventral to the colon on the lateral view consistent with uteromegaly and severe intestinal distention resembling intussusceptions. Conservative treatment was failed and the animal died. In necropsy, ileocecal intussusception was noted as the main death factor. Thickened uterine endometrium in both horns was observed and the uterus was filled with mucoid fluid. Both ovaries were multilobulated and distended. On the other hand, a small cyst sized 1.5 × 2.5 cm was diagnosed on the liver surface. Several samples were obtained from lesions for histopathological evaluation. Histopathologically, dilated cystic glands of variable size lined by densely packed epithelium and hyperplasia of the endometrium resulting in irregular folds or papillar projection into the lumen were evident and the sections of ovaries revealed ovarian luteoma that composed of polyhedral cells with pale stained vacuolated cytoplasm, centrally located nuclei with distinct cytoplasmic borders and the cytoplasm of cells contain lipid droplet. The occurrence of biliary cyst adenoma was confirmed by microscopic examination of the mass that composed of multicystic space in different sizes lined by flattened to cuboidal biliary epithelium with papillary projections. These cysts were seperated by variable amount of connective tissue. The lack of postmortem investigations in aged rabbits reduced the incidence of neoplastic disease diagnosis in this species. Whereas uterine adenecarcinoma and lymphosarcoma were commonly reported in rabbits, luteoma and biliary cyst adenoma that are well described in this case report were uncommon in rabbit medicine.

  18. Obeticholic acid for the treatment of primary biliary cirrhosis.

    2016-01-01

    Primary biliary cirrhosis (PBC) is characterized by progressive nonsuppurative destruction of small bile ducts, resulting in intrahepatic cholestasis, fibrosis and ultimately end-stage liver disease. Timely intervention with ursodeoxycholic acid is associated with excellent survival, although approximately one-third of all patients fail to achieve biochemical response, signifying a critical need for additional therapeutic strategies. Obeticholic acid (OCA) is a potent ligand of the nuclear hormone receptor farnesoid X receptor (FXR). Activation of FXR inhibits bile acid synthesis and protects against toxic accumulation in models of cholestasis and facilitates hepatic regeneration in preclinical studies. Data from recent Phase II and III controlled trials suggest a therapeutic impact of OCA in PBC biochemical nonresponders, as evidenced by change in proven laboratory surrogates of long-term outcome. Dose-dependent pruritus is a common adverse effect, but may be overcome through dose-titration. Longer term studies are needed with focus on safety and long-term clinical efficacy. PMID:26549695

    As the Food and Drug Administration trials for biliary lithotripsy in the United States near completion, future criteria for patient eligibility remain to be defined. Gallstone calcification greater than 3-mm partial rim on plain film (KUB) or oral cholecystogram (OCG) has excluded patients thus far, since early results of gallstone clearance (lithotripsy plus chemodissolution) were suboptimal with calcified stones. To evaluate the usefulness of these criteria for gallstone fragmentation, computed tomographic (CT) scans were performed on 20 patients immediately prior to lithotripsy to evaluate gallstone density and 24 hours after lithotripsy to observe the CT appearance of fragmentation. The adequacy of fragmentation was determined by pre- and post-lithotripsy sonography. This report constitutes the results of these investigations. PMID:10149158

    Background. Distal migration is one of the common complications after insertion of a covered metallic stent. Stent repositioning or removal is not always possible in every patient. Therefore, trimming using an argon plasma coagulator (APC) may be a good alternative method to solve this problem. Methods. Metallic stent trimming by APC was performed in 2 patients with biliary Wallstent migration and in another patient with esophageal Ultraflex stent migration. The power setting was 60-100 watts with an argon flow of 0.8 l/min. Observations. The procedure was successfully performed and all distal parts of the stents were removed. No significant collateral damage to the nearby mucosa was observed. Conclusions. In a patient with a distally migrated metallic stent, trimming of the stent is possible by means of an APC. This new method may be applicable to other sites of metallic stent migration

  1. Treatment of malignant and benign biliary obstructions with metal stents

    International Nuclear Information System (INIS)

    The palliative treatment of malignant bilary tract obstructions using a metal stent is now an established procedure in clinical practice. An endoscopic, transpapillary approach is the first choice for implantation of the stent. If it is not possible to insert the stent in this way, which is often the case with high obstructions, a percutaneous approach is chosen. It appears to be beneficial to use a metal stent with a finemeshed net such as, for example, the Wall stent. Metal stents have a higher patency rate than plastic stents so that the primary choice of a metal stent is justified. Coated stents have not yet shown any major advantages. In cases of stent occlusion the coaxial implantation of a plastic stent seems to be the most efficient. In cases of benign biliary tract stenoses, a metal stent should only be implanted after a careful evaluation of all possible surgical modalities and exploitation of balloon dilatation and long-term splinting methods.

    Full Text Available An increased prevalence of X chromosome monosomy has recently been demonstrated in patients with primary biliary cirrhosis (PBC. Chronic cholestasis of unknown etiology is a common clinical feature in patients with Turner syndrome who reach the fourth and fifth decades of life. A 37-year-old patient with Turner syndrome who presented with clinical and biochemical features of chronic cholestasis is described. Subsequent investigations confirmed the diagnosis of PBC. The patient did not respond to the medical treatment and was referred for liver transplant assessment. The present case may support the importance of X chromosome genes in the development of genetic predisposition to PBC, and emphasizes the necessity for a systematic study of the prevalence of PBC in patients with Turner syndrome.

    Biliary complications are being increasingly encountered in post liver transplant patients because of increased volume of transplants and longer survival of these recipients. Overall management of these complications may be challenging, but with advances in endoscopic techniques, majority of such patients are being dealt with by endoscopists rather than the surgeons. Our review article discusses the recent advances in endoscopic tools and techniques that have proved endoscopic retrograde cholangiography with various interventions, like sphincterotomy, bile duct dilatation, and stent placement, to be the mainstay for management of most of these complications. We also discuss the management dilemmas in patients with surgically altered anatomy, where accessing the bile duct is challenging, and the recent strides towards making this prospect a reality.

    The expanded indications of partial grafts in pediatric liver transplantation have reduced waiting list mortality. However, a higher morbidity is observed, including an increased rate of biliary complications(BCs). Factors such as the type of graft, the preservation methods applied, the donor characteristics, the type of biliary reconstruction, and the number of bile ducts in the liver graft influences the occurrence of these complications. Bile leaks and strictures comprise the majority of posttransplant BCs. Biliary strictures require a high grade of suspicion, and because most children have a bileoenteric anastomosis, its diagnosis and management rely on percutaneous hepatic cholangiography and percutaneous biliary interventions(PBI). The success rates with PBI range from 70% to 90%. Surgery is reserved for patients who have failed PBI. BCs in children after liver transplantation have a prolonged treatment and are associated with a longer length of stay and higher hospital costs. However, with early diagnosis and aggressive treatment, patient and graft survival are not significantly compromised.

  17. Combined treatment with metallic stent placement and radiotherapy in malignant biliary obstruction

    International Nuclear Information System (INIS)

    To evaluate the efficacy of combined treatment of metallic biliary stent placement and radiotherapy in malignant biliary obstruction. Between January 1992 and February 1994, 22 patients with malignant biliary obstruction were treated with metallic biliary stent placement and radiotherapy. The causes of the obstruction included cholangio carcinoma(n=14), gallbladder carcinoma(n=4), colon cancer(n=2), pancreatic head cancer (n=1), and stomach cancer(n=1). According to the sites of obstruction level, patient were divided into 2 groups; hilar obstruction(n=18) and common bile duct obstruction(n=4). The patients received dose of 45 Gray/18 fraction by external radiotherapy and 20Gy/8f by high dose rate brachytherapy with iridium-192 source through percutaneous transhepatic biliary drainage(PTBD) catheter. The duration of stent patency after placement, survival period and survival rate by Kaplan Meier method were calculated in dead and alive patients, respectively. In all 22 patients, the duration of stent patency was 5.5(1.3-18.5)months. Survival periods after stent placement and PTBD were 5.3(2.0-8.5 )months and 7.9(4.0-14.7)months respectively in 9 dead patients and 7.7(1.3-21.0)months and 9.5(2.3-23.0)months in 13 alive patients. In all 22 patients, the survival rates in 6, 12 and 18 months were 78.9%, 47.5% and 35.6 %, respectively. The results with combined metallic biliary stent placement and radiotherapy for the palliative treatment of malignant biliary obstruction in this study was more favorable, as compared with those of the other authors with only metallic biliary stent placement

  3. Detection of biliary stenoses in patients after liver transplantation: Is there a different diagnostic accuracy of MRCP depending on the type of biliary anastomosis?

    International Nuclear Information System (INIS)

    Purpose: Two different forms of biliary anastomosis can be created in patients undergoing liver transplantation: (a) bilio-digestive anastomoses or (b) choledocho-choledochostomy. Aim of this study was to assess the accuracy of MR cholangiopancreatography (MRCP) for the depiction of biliary stenoses in liver transplant patients depending on the type of biliary anastomosis. Method and materials: 24 liver transplant patients with clinical suspicion of biliary stenosis were studied (each 12 with bilio-digestive anastomosis/choledocho-choledochostomy). MRCP was performed on a 1.5T scanner (Magnetom Avanto, Siemens) including 2D single shot RARE, 2D T2w HASTE, TrueFISP and 3D high-resolution navigator corrected sequences. Presence of (a) anastomotic stenoses (AST) and (b) NAS (non-anastomotic strictures) were assessed. Percutaneous transhepatic cholangiography (PTC) or endoscopic retrograde cholangiopancreatography (ERCP) were performed within 48 h after MRCP and served as the standard of reference. Results: In patients with bilio-digestive anastomoses sensitivities of MRCP for the detection of AST and NAS amounted to 50% and 67%, respectively with specificity values of 83% and 50%. In patients with choledocho-chledochostomy sensitivities (AST: 100%, NAS: 100%) and specificities (AST: 100%, NAS: 88%) were significantly higher. Conclusion: Biliary strictures after liver transplantation can be accurately detected by MRCP in patients after choledocho-chledochostomy. However, the diagnostic value of MRCP is lower if liver transplantation was performed in combination with a bilio-digestive anastomosis. This may be due to the less exact depiction of the anastomosis in the bowel wall. Thus, it is crucial to know the type of biliary anastomosis before choosing a diagnostic procedure.

    We attempted to detect mutagenic activity in bile and pancreatic juice from patients with biliary tract disease using the spore rec assay and wild (H17) and mutant (M45) strains. Three bile samples out of 5 obtained from patients with pancreatico-biliary maljunction showed positive reaction in the spore rec assay, and all contained a high level of amylase activity, while 300 microliters of bile samples obtained from 10 control patients without pancreatico-biliary maljunction did not show any positive reaction. Moreover, 300 microliters of the in vitro mixture of bile with an equal volume of pancreatic juice also showed a positive reaction after treatment for 12 days at 37 degrees C or for 10 min at 100 degrees C, suggesting that they were very stable and long-acting in vivo. These data suggest that possible mutagens might be formed by the mixing of bile with pancreatic juice regurgitated into the biliary tract, and that there might be a relationship to biliary tract cancer which often accompanies pancreatico-biliary maljunction.

    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.

    Purpose. Previous clinical studies have shown the safety and efficacy of this novel radiofrequency ablation catheter when used for endoscopic palliative procedures. We report a retrospective study with the results of first in man percutaneous intraductal radiofrequency ablation in patients with malignant biliary obstruction. Methods. Thirty-nine patients with inoperable malignant biliary obstruction were included. These patients underwent intraductal biliary radiofrequency ablation of their malignant biliary strictures following external biliary decompression with an internal-external biliary drainage. Following ablation, they had a metal stent inserted. Results. Following this intervention, there were no 30-day mortality, hemorrhage, bile duct perforation, bile leak, or pancreatitis. Of the 39 patients, 28 are alive and 10 patients are dead with a median survival of 89.5 (range 14-260) days and median stent patency of 84.5 (range 14-260) days. One patient was lost to follow-up. All but one patient had their stent patent at the time of last follow-up or death. One patient with stent blockage at 42 days postprocedure underwent percutaneous transhepatic drain insertion and restenting. Among the patients who are alive (n = 28) the median stent patency was 92 (range 14-260) days, whereas the patients who died (n = 10) had a median stent patency of 62.5 (range 38-210) days. Conclusions. In this group of patients, it appears that this new approach is feasible and safe. Efficacy remains to be proven in future, randomized, prospective studies.

Of the 39 patients, 28 are alive and 10 patients are dead with a median survival of 89.5 (range 14–260) days and median stent patency of 84.5 (range 14–260) days. One patient was lost to follow-up. All but one patient had their stent patent at the time of last follow-up or death. One patient with stent blockage at 42 days postprocedure underwent percutaneous transhepatic drain insertion and restenting. Among the patients who are alive (n = 28) the median stent patency was 92 (range 14–260) days, whereas the patients who died (n = 10) had a median stent patency of 62.5 (range 38–210) days. Conclusions. In this group of patients, it appears that this new approach is feasible and safe. Efficacy remains to be proven in future, randomized, prospective studies.

    Objective. To elucidate the optimum preoperative biliary drainage method for patients with pancreatic cancer treated with neoadjuvant chemotherapy (NAC). Material and Methods. From January 2010 through December 2014, 20 patients with borderline resectable pancreatic cancer underwent preoperative biliary drainage and NAC with a plastic or metallic stent and received NAC at Hiroshima University Hospital. We retrospectively analyzed delayed NAC and complication rates due to biliary drainage, effect of stent type on perioperative factors, and hospitalization costs from diagnosis to surgery. Results. There were 11 cases of preoperative biliary drainage with plastic stents and nine metallic stents. The median age was 64.5 years; delayed NAC occurred in 9 cases with plastic stent and 1 case with metallic stent (p = 0.01). The complication rates due to biliary drainage were 0% (0/9) with metallic stents and 72.7% (8/11) with plastic stents (p = 0.01). Cumulative rates of complications determined with the Kaplan-Meier method on day 90 were 60% with plastic stents and 0% with metallic stents (log-rank test, p = 0.012). There were no significant differences between group in perioperative factors or hospitalization costs from diagnosis to surgery. Conclusions. Metallic stent implantation may be effective for preoperative biliary drainage for pancreatic cancer treated with NAC. PMID:26880897

  11. Ultrasound-guided percutaneous cholecysto-cholangiography for the exclusion of biliary atresia in infants

    International Nuclear Information System (INIS)

    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

    Full Text Available We herein report the clinicopathologic features of a rare case of biliary adenofibroma (BAF of the liver in a 79-year-old man. Grossly, tumour presented as a well-circumscribed, 5.5-cm mass with a solid and microcystic appearance. Histological examination was typical of biliary adenofibroma, showing a proliferation of variable-sized tubulocystic structures embedded in a moderately cellular fibrous stroma. Immunohistochemistry, revealing immunoreactivity of the epithelial component to cytokeratins 7 and 19, was consistent with a bile duct origin. Notably, the stromal cells had a myofibroblastic profile, showing a diffuse and strong expression of vimentin and -smooth muscle actin. Differential diagnosis with Von Meyenburg complex, biliary adenoma, biliary cistadenoma, congenital biliary cystsy, and hepatic benign cystic mesothelioma is provided. The occasionally reported expression of p53 in biliary adenofibroma has suggested that this tumour could represent a premalignant lesion. The absence of both cytological atypia and p53 immunoreactivity in our case confirms that BAF is a benign tumour with an indolent clinical behaviour. However, a careful histological examination of BAF is mandatory because malignant transformation of the epithelial component has been documented in two cases.

    Full Text Available Abstract Background Partial External Biliary Diversion (PEBD is a surgical intervention to treat children with Progressive Familial Intrahepatic Cholestasis (PFIC and Alagille syndrome (AGS. PEBD can reduce disease progression, and examining the alterations in biliary lipid composition may be a prognostic factor for outcome. Methods Biliary lipid composition and the clinical course of AGS and PFIC patients were examined before and after PEBD. Results Pre-PEBD bile from AGS patients had greater chenodeoxycholic/cholic acid (CDCA/CA, bile salt, cholesterol and phospholipid concentrations than PFIC patients. AGS patients, and PFIC patients with familial intrahepatic cholestasis 1 (FIC1 genotype, responded better to PEBD than PFIC patients with bile salt export protein (BSEP genotype. After successful PEBD, AGS patients have higher biliary lipid concentrations than PFIC patients and PEBD also increases biliary phospholipid concentrations in FIC1 patients. Conclusion Both AGS and FIC1 patients can benefit from PEBD, and preserved biliary phospholipid concentrations may be associated with better outcomes post-PEBD.

    Our objective was to describe our technique for multislice CT cholangiography without cholangiographic contrast agent, and to present our preliminary clinical results. Thirty-seven patients with suspected biliary obstruction were studied. A multislice CT unit was used with the following technical parameters: 2.5-mm collimation; 7.5-mm/s table speed; pitch 6; 0.8-s rotation time; 300 mA; 120 kVp; 18- to 24-s scan time; scan volume ranging from the hepatic dome to below the pancreatic head; 70-s delay after injection of 150 ml of iodinated contrast agent at 4 ml/s. No biliary contrast material was given; oral iodinated contrast agent was administered to opacify bowel loops. Axial, multiplanar reformatted, and minimum intensity projection images were evaluated. The CT findings were compared with the gold standard techniques: endoscopic retrograde cholangiography (ERCP) in 30 patients, percutaneous transhepatic cholangiography in 5, and intraoperative cholangiography in 2. In 5 patients with ampullary lesions biopsy was made during ERCP, 9 underwent surgery, and 11 US-guided fine-needle aspiration. Bile ducts appeared hypodense within the surrounding enhanced structures. Regarding the site of obstruction, agreement between multislice CT and conventional cholangiography was observed in all cases. One patient presented negative findings on both CT and ERCP. In 31 of 36 (86%) patients, multislice CT cholangiography without cholangiographic contrast agent correctly assessed the cause of bile duct obstruction. Multislice CT cholangiography without cholangiographic contrast agent seems to be a promising diagnostic tool in the assessment of patients with bile duct obstruction. (orig.)
