    Biliary cystadenocarcinoma is a very rare malignant cystic tumor of the liver, which is often misdiagnosed due to a poor recognition of it. We report a case of a 60-year-old man with biliary cystadenocarcinoma with his real time contrast enhanced ultrasound (CEUS) characteristics compared to those of computed tomography (CT) and magnetic resonance imaging (MRI), which were correlated with the surgical and pathologic findings. Cystic wall enhancement, internal septations and intra-cystic solid...

    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.

    Fasciola hepatica infection may result in biliary obstruction with or without cholangitis in the chronic biliary phase. Because clinical symptoms and signs of F. hepatica are similar to other biliary diseases that cause bile duct obstruction, such as stones or bile duct malignancies, that are, in fact, more common, this condition may not be suspected and diagnosis may be overlooked and delayed. Patients undergoing endoscopic retrograde cholangiopancreatography or endoscopic ultrasonography for the evaluation of bile duct obstruction may be incidentally detected with the worm, and diagnosis can be confirmed by extraction of the leaf-like trematode from the bile duct. Intraductal ultrasonography (IDUS) can provide high-resolution cross-sectional images of the bile duct, and is useful in evaluating indeterminate biliary diseases. We present a case of biliary fascioliasis that was diagnosed using IDUS and managed endoscopically in a patient with acute cholangitis. PMID:26668810

    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.

    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)

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

  16. Computed tomography of primary intrahepatic biliary malignancy

    International Nuclear Information System (INIS)

    Fifteen patients with primary intrahepatic biliary malignancy (cholangiocarcinoma in 13, biliary cystadenocarcinoma in two) were examined by computed tomography (CT). The CT features were classified into three types: (A) a well-defined round cystic mass with internal papillary projections, (B) a localized intrahepatic biliary dilatation without a definite mass lesion, and (C) miscellaneous low-density masses. Intraphepatic biliary dilatation was noted in all cases of Types A and B and half of those of Type C; dilatation of extrahepatic bile ducts occurred in 4/4, 1/3, and 0/8, respectively. CT patterns, such as a well-defined round cystic mass with papillary projections or dilatation of intra- and extrahepatic ducts, give important clues leading to a correct diagnosis of primary intrahepatic biliary malignancy

    A 57-year-old man with a history of tuberculosis (TB) was found to have a pancreatic head mass, accompanied by stenosis of the common bile duct. Due to the inherent difficulty in differentiating pancreatic carcinoma from an inflammatory mass, endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) was thus performed. The pathological findings confirmed granuloma with caseous necrosis, and the results of the QuantiFERON TB2G test were positive. Accordingly, the patient was diagnosed with peripancreatic TB and thereafter was successfully treated with anti-TB therapy. Based on the findings of this case, we conclude that EUS-FNAB is a useful modality for the diagnosis of pancreatic TB. PMID:27086805

    Full Text Available An 11-year-old female German Shepherd dog was presented for investigation of progressive enlargement of the abdomen, periodic bloody discharge from the vulva and rapid exhaustion. Transabdominal ultrasonography and lateral abdominal radiography demonstrated an echogenic formation with anechogenic cavities located cranial to the urinary bladder and a homogeneous shadow with an elliptical shape was located caudal to the rib arc. Both showed indistinct borders. Exploratory laparotomy identified bilateral ovarian masses and ovariohysterectomy was performed. Histopathology confirmed ovarian cystadenocarcinoma. The dog remained clinically normal without evidence of metastatic disease 4 months after surgery. Papillary cystadenocarcinoma in the bitch could affect both ovaries and manifests with a rapid growth rate and clinical signs such as rapid exhaustion, abdominal enlargement and vulval discharge. Ovariohysterectomy is the treatment option.

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.

  2. Biliary ascariasis

    International Nuclear Information System (INIS)

    Biliary ascariasis is a complication of intestinal ascariasis. This results in characteristic findings in the intravenous cholangiocholecystogram and in the sonogram. Characteristic signs of biliary ascariasis are, in the longitudinal section, the 'strip sign', 'spaghetti sign', 'inner tube sign', and in transverse section 'a bull's eye in the triple O'. The helminth can travel from out of the biliary duct system back into the intestinum, so that control examinations can even be negative. (orig.)

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.

  4. Hepatobiliary scintigraphy in the assessment of biliary obstruction after hepatic resection with biliary-enteric anastomosis

    International Nuclear Information System (INIS)

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

    Full Text Available Abstract Introduction Primary pulmonary mucinous cystadenocarcinoma is a rare variety of lung cancer. It is characterized pathologically by copious mucin production predominantly in the extracellular space. This tumour has a remarkably favorable prognosis. Case presentation We present imaging and histopathological findings of primary pulmonary mucinous cystadenocarcinoma presenting as a complex bronchocele in a 67-year-old Caucasian woman. Conclusion Diagnosis of pulmonary mucinous cystadenocarcinoma should be considered in patients presenting with bronchocele that has suspicious imaging features, because the results of fine needle aspiration cytology and bronchoscopy are frequently inconclusive in these tumours. Positive emission tomography has an important role in helping to identify these tumours.

    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 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.

    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.

    2009-01-01

    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.

    2016-01-01

    Giant cystadenocarcinomas of the ovary are rarely described. Huge ovarian masses are mostly benign, but malignancy should be ruled out by investigations and clinical assessment. Giant cysts require resection because of compressive symptoms or risk of malignancy and their management invariably requires laparotomy to prevent perforation and spillage of the cyst fluid into peritoneal cavity. Here, we present a case of a 42-year-old female with severe and rapidly growing abdominal distension operated for exploratory laparotomy for cystic mass excision. On histology, mass was found to be metastatic mucinous cystadenocarcinoma with omental metastasis. The diagnostic and management challenges posed by this unexpected and unusual presentation of an ovarian cystadenocarcinoma are discussed. The main aim of this report is to draw attention to huge ovarian epithelial cysts with unsuspected presentation contributing to a decrease in any underdiagnosis, misdiagnosis, and mismanagement that might occur.

    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.

  5. Biliary endoprosthesis

    International Nuclear Information System (INIS)

    Biliary endoprosthesis could provide permanent internal biliary drainage in patient with obstructive jaundice with advantages of absence of troublesome external catheter and no loss of fluid, bile and electrolytes over external drainage. Incidence of sepsis and cholangitis be lowered. Endoprosthesis was performed in 18 patients of obstructive jaundice from January, 1985 to December, 1985 at Department of Radiology, Kyungpook National University Hospital. The results are as follows 2. The cases of obstructive jaundice included bile duct cancer in 11, stomach ca. metastasis in 3, ca. of ampulla of Vater in 1, ca. of head of pancreas in 1, CBD cancer with postop. recurrence in 1, and impacted CBD stone in 1 case. 2. The levels of obstruction were at the trifurcation in 8, CHD in 5, proximal CBD in 3, and distal CBD in 2 cases. 3. Decline of serum bilirubin level was noted in 15 cases with the most rapid decline within 1 week after the procedure. 4. The complication occurred in 5 cases. The three cases were recovered spontaneously, but one died of bile peritonitis, another experienced obstruction of endoprosthesis. 5. The endoprosthesis is beneficial in treatment of obstructive jaundice for which surgery is not indicated, and saving expensive abdominal surgery and less advantageous percutaneous external drainage, hence enhancing life quality.

  7. Malignant biliary obstruction

    International Nuclear Information System (INIS)

    This paper assesses the value of CT in predicting surgical resectability of tumors in patients with malignant biliary obstruction. A retrospective analysis was performed on 320 consecutive patients with malignant biliary obstruction over a 3-1/2-year period. Most patients were treated nonoperatively. Fifty-one patients fulfilled the selection criteria of surgical exploration, pathological confirmation of malignancy, and prepoperative CT scans available for review. The CT scans were reviewed by a blinded reader and assessed for surgical resectability of tumors. There were 32 patients with pancreatic adenocarcinoma, 6 with ampullary carcinoma, 5 with cholangiocarcinoma, 2 with gallbladder carcinoma, and 6 with other pathologic diagnoses. Of 36 patients thought to have unresectable tumors based on CT findings, 32 were found to have surgically unresectable tumors (positive predictive value, 89%). Of 15 patients thought to have resectable tumors based on CT findings, 11 had surgically resectable tumors (positive predictive value, 73%). CT missed positive duodenal lymph nodes in 2 patients, portal vein infiltration in 1 patient, and small liver metastases in 1 patient

    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

    CASE DESCRIPTION A 7-year-old 42-kg (92.4-lb) sexually intact nulliparous female Italian Mastiff was examined because of a history of vaginal prolapse during diestrus. CLINICAL FINDINGS A physical examination revealed vaginal fold prolapse. Abdominal ultrasonography revealed an enlarged uterus with hypoechogenic content, corpora lutea in the ovaries, and a cyst in the right ovary. Hematologic abnormalities included leukocytosis, neutrophilia, mild anemia, and low Hct. Progesterone and estradiol concentrations were 9.36 ng/mL and 30.42 pg/mL, respectively, in serum and 72.72 ng/mL and 792 pg/mL, respectively, in the ovarian cystic fluid. TREATMENT AND OUTCOME Ovariohysterectomy was performed; the prolapsed tissue was repositioned by external manipulation and maintained in situ by temporary apposition of the vulvar lips with a retention suture. Anatomic and histologic examinations of the excised tissues revealed pyometra and papillary cystadenocarcinoma in the right ovary. The vaginal hyperplasia completely regressed at 35 days after surgery; 5 months after surgery, the dog's general condition was considered good. CLINICAL RELEVANCE Findings in this case were indicative of a hormonally active ovarian papillary cystadenocarcinoma in a female dog in diestrus. Hormone production by the cystadenocarcinoma was the predisposing factor that induced pyometra, mucosal hyperplasia, and vaginal fold prolapse in the dog. On the basis of these concurrent disorders, ovariohysterectomy was an appropriate treatment. (J Am Vet Med Assoc 2016;248:822-826). PMID:27003024

    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.

    2006-01-01

    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.

    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

    OK-432 is an immunomodulator that has been reported to be efficacious as an injection therapy for cervical lymphomas and ranulas. We performed OK-432 injection therapy to treat a cystadenocarcinoma of the parotid gland in a 72-year-old man. The 50 × 46-mm tumor was located in the deep lobe of the gland. The tumor had compressed the glossopharyngeal, vagus, and hypoglossal nerves, causing neurally mediated syncope, hoarseness, dysphagia, and dysarthria. A concentration of 5 KE/2 ml of OK-432 was injected. Within 2 months, the cyst had disappeared; no recurrence was apparent during 59 months of follow-up. To the best of our knowledge, no previous report has described injection of OK-432 for malignant cystic disease. We describe the injection method, injection dose, and postinjection course in the hope that this information will prove useful for future applications against malignant cystic disease. PMID:27140021

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 etiology of biliary tract cancer is obscure, but there are evidences that bile acid plays a role in carcinogenesis. To find the association between biliary tract cancer and bile acid, this study compared the bile acid concentration and composition among patients with biliary cancer, biliary tract stones, and no biliary disease. Bile was compared among patients with biliary tract cancer (n = 26), biliary tract stones (n = 29), and disease free controls (n = 9). Samples were obtained by per...

    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

  10. Percutaneous Transhepatic Biliary Drainage in the Management of Postsurgical Biliary Leaks in Patients with Nondilated Intrahepatic Bile Ducts

    International Nuclear Information System (INIS)

    Purpose. To assess the feasibility of percutaneous transhepatic biliary drainage (PTBD) for the treatment of postsurgical biliary leaks in patients with nondilated intrahepatic bile ducts, its efficacy in restoring the integrity of bile ducts, and technical procedures to reduce morbidity. Methods. Seventeen patients out of 936 undergoing PTBD over a 20-year period had a noncholestatic liver and were retrospectively reviewed. All patients underwent surgery for cancer and suffered a postsurgical biliary leak of 345 ml/day on average; 71% were in poor condition and required permanent nutritional support. An endoscopic approach failed or was excluded due to inaccessibility of the bile ducts. Results. Established biliary leaks and site of origin were diagnosed an average of 21 days (range 1-90 days) after surgery. In all cases percutaneous access to the biliary tree was achieved. An external (preleakage) drain was applied in 7 cases, 9 patients had an external-internal fistula bridging catheter, and 1 patient had a percutaneous hepatogastrostomy. Fistulas healed in an average of 31 days (range 3-118 days ) in 15 of 17 patients (88%) following PTBD. No major complications occurred after drainage. Post-PTBD cholangitis was observed in 6 of 17 patients (35%) and was related to biliary sludge formation occurring mostly when drainage lasted >30 days and was of the external-internal type. Median patient survival was 17.7 months and in all cases the repaired biliary leaks remained healed. Conclusions. PTBD is a feasible, effective, and safe procedure for the treatment of postsurgical biliary leaks. It is therefore a reliable alternative to surgical repair, which entails longer hospitalization and higher costs

    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

    2015-09-01

    Only 20-30% of patients with hilar cholangiocarcinoma (CC) are candidates for potentially curative resection. However, even after curative (R0) resection, these patients have a disease recurrence rate of up to 76%. The prognosis of hilar cholangiocarcinoma (CC) is limited by tumor spread along the biliary tree leading to obstructive jaundice, cholangitis, and liver failure. Therefore, palliative biliary drainage may be a major goal for patients with hilar CC. Endoscopic retrograde cholangiopancreatography (ERCP) with stent placement is an established method for palliation of patients with malignant biliary obstruction. However, there are patients for whom endoscopic stent placement is not possible because of failed biliary cannulation or tumor infiltration that limits transpapillary access. In this situation, percutaneous transhepatic biliary drainage (PTBD) is an alternative method. However, PTBD has a relatively high rate of complications and is frequently associated with patient discomfort related to external drainage. Endoscopic ultrasound-guided biliary drainage has therefore been introduced as an alternative to PTBD in cases of biliary obstruction when ERCP is unsuccessful. In this review, the indications, technical tips, outcomes, and the future role of EUS-guided intrahepatic biliary drainage, such as hepaticogastrostomy or hepaticoduodenostomy, for hilar biliary obstruction will be summarized.

    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

Forty patients were classified as having biliary pancreatitis and 20 patients as having the nonbiliary type. Scintigraphic scans were divided into five main types according to the time to visualization of the gallbladder and the time to excretion of 99/sup m/Tc-PIPIDA into the intestinal tract. Normal scans were obtained in 95% of patients (19/20) with nonbiliary pancreatitis; 22.5% of patients (9/40) with biliary pancreatitis had normal scans. It is concluded that elevated amylase levels together with an abnormal biliary scan, as defined by the criteria presented here, indicate biliary pancreatitis, while a normal scan largely excludes such diagnosis

We compared serum Salmonella enterica serovar Typhi antibody titers between biliary tract cancer cases, biliary stone cases without evidence of cancer, and healthy subjects in a large population-based case-control study in Shanghai, China. Participants included 627 newly diagnosed primary biliary tract cancer patients; 1,037 biliary stone cases (774 gallbladder and 263 bile-duct and 959 healthy subjects without a history of cancer, randomly selected from the Shanghai Resident Registry. Overall only 6/2,293 (0.26% were Typhi positive. The prevalence of Typhi was 1/457 (0.22%, 4/977 (0.41%, and 1/859 (0.12% among cancer cases, biliary-stone cases, and population controls, respectively. We did not find an association between Typhi and biliary cancer in Shanghai, due to the very low prevalence of chronic carriers in this population. The low seroprevalence of S. Typhi in Shanghai is unlikely to explain the high incidence of biliary cancers in this population.

    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.)

    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.

    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.

    Full Text Available Iatrogenic bile duct injury carries a high rate of morbidity. After the introduction of laparoscopiccholecystectomy the incidence of these injuries has at least doubled, and even after the learningcurve, the incidence has remained of about 0.5%. Etiology of the iatrogenic biliary injuries is theresult of the anatomical conditions (biliary or vascular anomalies, pathology (acute cholecystitis,adhesions, technical equipment, surgeon (the lerning curve. The type of the injuries, thediagnostic procedures and therapeutic approach are discussed. Most of the minor bile duct injuries,including cystic duct leaks and bile duct strictures, are well treatable with endoscopic techniques,whereas most of the major injuries require operative treatment, which at optimal circumstancesgives good results. Interdisciplinary cooperation and early referral to an experienced center iscrucial in the management of these iatrogenic lesions. The best „treatment” for this iatrogenicpathology is prevention: surgical access adapted to morphology, good exposure of the hepatoduodenalspace, good identification of structures before tying, appropriate dissection, selectivecholangiography, great care with the use of electrosurgery.

    Primary biliary cirrhosis (PBC) is an idiopathic chronic autoimmune liver disease that primarily affects women. It is believed that the aetiology for PBC is a combination between environmental triggers in genetically vulnerable persons. The diagnosis for PBC is made when two of the three criteria are fulfilled and they are: (1) biochemical evidence of cholestatic liver disease for at least 6 month's duration; (2) anti-mitochondrial antibody (AMA) positivity; and (3) histologic features of PBC on liver biopsy. Ursodeoxycholic acid (UDCA) is the only FDA-approved medical treatment for PBC and should be administered at a recommended dose of 13-15 mg/kg/day. Unfortunately despite adequate dosing of UDCA, approximately one-third of patients does not respond adequately and may require liver transplantation. Future studies are necessary to elucidate the role of environmental exposures and overall genetic impact not only in the development of PBC, but on disease progression and variable clinical response to therapy.

  16. Percutaneous transhepatic biliary endoprostheses

    International Nuclear Information System (INIS)

    Eighty biliary endoprostheses were introduced by the transhepatic route in sixty patients with obstructive jaundice. Complication rate was 21% (no mortality). Average survival time is sixteen weeks (maximum 53 weeks). In most patients, a 12 F teflon endoprosthesis was introduced four to five days after the initial catheter drainage. Patients in poor condition had a primary implant of a 9 F endoprosthesis. A combined transhepatic/transoral implantation was carried out five times. Results have shown that implantation of a prosthesis is as effective as a surgical bypass operation for palliation of obstructive jaundice and that it is better than catheter drainage. In-vitro experiments have indicated that failure of a 12 F prosthesis due to encrustation may be expected in about 23 weeks. This is in line with the survival time of patients with carcinomas.

    International Nuclear Information System (INIS)

    The authors have developed their own technique for percutaneous transhepatic biliary drainage (PTD) which they describe. Results of drainages performed since 1977 are presented. As a special application, the authors have also developed a radiation technique, according to the after-loading-method and using PTD. Similar to the intracavitary irradiation of gynecological tumors, a very high dose can be directly applied to the tumour with use of low volume dose and sparing of the neighbouring healthy tissue. The previously inserted drainage catheter is exchanged for a wide bore Teflon-tube and the radiation source Ir-192 is automatically advanced into the tumour stenosis. The isodose distribution is subsequently made under computer assisted guidance. (Auth.)

    2016-01-01

    Endobiliary radiofrequency ablation (RFA) has recently been recognized as a beneficial treatment option for malignant biliary obstruction using percutaneous or endoscopic approaches. The feasibility and safety of this method has been demonstrated in clinical studies, with pain, cholangitis and asymptomatic biochemical pancreatitis reported as relatively common complications. By contrast, hepatic coma, newly diagnosed left bundle branch block and partial liver infarction have been reported as uncommon complications. Biliary tract perforation is a serious potential complication of percutaneous intraductal RFA, which may result in severe infection, peritonitis or even mortality, and which has not been previously reported in clinical research. The current study presents the first reports of biliary tract perforation in two patients with unresectable malignant biliary obstruction following percutaneous intraductal RFA. Although the patient in case 1 succumbed 12 days after RFA, the minor biliary tract perforation in case 2 was successfully treated by the deployment of a self-expanding metal stent. This study demonstrates that biliary tract perforation should be recognized as a serious potential complication of endobiliary RFA, and that metal stent deployment should be considered as a treatment option for minor biliary tract perforation.

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

    AIM: To analyze phospholipid profiles in intrahepatic bile from patients with primary sclerosing cholangitis (PSC) and secondary sclerosing cholangitis (SSC). METHODS: Intrahepatic bile specimens collected via endoscopic retrograde cholangiography from 41 patients were analyzed. Fourteen of these patients were diagnosed with PSC, 10 with SSC, 11 with choledocholithiasis or no identifiable biliary disease, and 6 with cholangiocellular carcinoma (CCC). Bile acid, cholesterol, protein, and bilirubin contents as well as pancreas lipase activity in bile were determined by biochemical methods. Phosphatidylcholine (PC) and lysophosphatidylcholine (LPC) species were quantified using nano-electrospray ionization tandem mass spectrometry. RESULTS: Bile from all the examined patient groups showed a remarkably similar PC and LPC species composition, with only minor statistical differences. Total biliary PC concentrations were highest in controls (8030 ± 1843 μmol/L) and lowest in patients with CCC (1969 ± 981 μmol/L) (P = 0.005, controls vs SSC and CCC, respectively, P < 0.05). LPC contents in bile were overall low (4.2% ± 1.8%). Biliary LPC/PC ratios and ratios of biliary PC to bilirubin, PC to cholesterol, PC to protein, and PC to bile acids showed no intergroup differences. CONCLUSION: PC and LPC profiles being similar in patients with or without sclerosing cholangitis, these phospholipids are likely not of major pathogenetic importance in this disease group.

  4. Biliary Stones: An atypical cause of abdominal pain in Paediatric age group

    International Nuclear Information System (INIS)

    Objective: To identify Paediatric patients with biliary stone disease presenting to a tertiary care hospital in order to determine the etiology, presentation and management. Methods: Retrospective study of all cases of ultrasonographically proven biliary stones under the age of 15 years from January 1988 to December 2008. Data included their risk factors, complications, management and outcome. Results: Total 32 patients were identified with biliary stones, treated in the hospital. Mean age at presentation was 8.25 +- 3.33 years. Sixteen patients underwent cholecystectomy. Conclusion: Paediatric cholelithiasis is an atypical and under-diagnosed cause of abdominal pain in childhood. True prevalence of the disease may be higher than reported. Appropriate surgical intervention is required in patients with symptomatic and complicated biliary lithiasis. (author)

    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.

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

    The value of biliary scintigraphy was studied in 180 patients with suspected biliary tract disease. Most of the patients were investigated additionally by conventional techniques such as cholecystography, cholangiography and ultrasonography. It is concluded that biliary scintigraphy is a simple and safe technique for visualization of the biliary tract. It is particularly useful in the evaluation of acute cholecystitis, in patients with iodine sensitivity obstructive from nonobstructive jaundice.

    To explore the potential role of computed tomographic cholangiography (CTC) in relation to magnetic resonance cholangiography (MRC) in cases in which knowledge of biliary kinetics and functional information are important for therapeutic decisions, 31 patients (14 men and 17 women) underwent MRC followed by CTC. We examined nine post-cholecystectomy cases with right upper quadrant abdominal pain, six cases with a previous biliary-enteric anastomosis and clinical evidence of cholangitis, eight biliary strictures with pain or symptoms of cholangitis, four cases with strong clinical evidence of sclerosing cholangitis, three cases with suspected post-laparoscopic cholecystectomy bile leakage, and one case with chronic pancreatitis and a common bile duct stent associated with cholangitis. In relation to MRC, CTC provided additional biliary functional information as follows: abnormal biliary drainage through the ampulla in 7/9 cholecystectomy cases, impaired drainage in 3/6 biliary-enteric anastomoses, and complete obstruction in 2/8 biliary strictures. CTC diagnosed early sclerosing cholangitis in 4/4 cases and confirmed suspected bile leakage in 1/3 post-laparoscopic cholecystectomy patients, and the patency of the biliary stent in the patient with chronic pancreatitis. Thus, CTC provides clinically important information about the function and kinetics of bile and complements findings obtained by MRC. (orig.)

  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

  18. 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.

    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...

    Endoscopic retrograde cholangio-pancreatography is the most appropriate technique for treating common bile duct and pancreatic duct stenosis secondary to benign and malignant diseases. Even if the procedure is performed by skillful endoscopist, there are patients in whom endoscopic stent placement is not possible. Common causes of failure include complex peri-papillary diverticula, prior surgery procedures, tumor involvement of the papilla, biliary sphincter stenosis, and impacted stones. Per...

  6. Initial clinical experience on improved percutaneous transhepatic biliary drainage in the treatment of malignant obstruction of the proximal biliary

    International Nuclear Information System (INIS)

    Objective: To investigate feasibility and clinical application value of improved percutaneous transhepatic biliary internal-external drainage (PTBIED). Methods: Consecutive patients from April 2007 to April 2010 with malignant obstructive jaundice were diagnosed by medical imaging or pathological confirmation whenever possible. The patients with proximal malignant biliary obstruction and intact inferior common bile ducts > 3 cm in length, and a bilirubin of 70 μmol/L or higher, were included in the experimental group. The control group included patients with low malignant biliary obstruction, and those who met the criteria for the exper/mental group but refused to receive the altered method of PTBIED. The patients underwent traditional PTBIED in control group. The patients in the experimental group received the procedure as following: according to percutaneous transhepatic cholangiography, a biliary external drainage catheter was modified by adding side-holes. Then under fluoroscopic guidance, the loop tip of the modified biliary drainage catheter was positioned in the inferior common hepatic duct/common bile duct, while the additional side-holes were located in the expanded hepatic duct. Technical success rate, complications, hepatic function and white cell count (WBC) were recorded pre- and post-procedure. All patients were followed-up until death. A t-test was used to compare continuous variable data changes, the Chi-square test was used to compare categorical variable data in two groups, and survival time was assessed using the Kaplan-Meier method. Results: Forty-six patients were included in the study, with 21 in the experimental group and 25 in the control group. The procedures were successfully performed in all patients in the two groups. There was no procedure-related death in the two groups. Symptoms were improved similarly after procedures in the two groups.

Alguns estudos sugerem um aumento do risco de neoplasia em pacientes com esclerose sistêmica (ES, mas a associação com neoplasia de ovário, principalmente do subtipo mucinoso, não é comum. Os autores descrevem um caso de cistoadenocarcinoma mucinoso de ovário em uma mulher branca de 52 anos com diagnóstico de ES difusa há seis anos, tratada previamente com D-penicilamina e ciclofosfamida, que procurou o serviço médico com queixa de dor e aumento do volume abdominal há três meses. Ao exame físico apresentava facies esclerodérmica, membros superiores com diminuição da elasticidade e enxerto bitibial em membros inferiores; no abdome havia a presença de uma massa endurecida estendendo-se da região suprapúbica até o epigástrio. Foi realizada laparotomia exploradora onde se encontrou uma massa cística no ovário direito, com peso de 3.300 gramas. Em seguida procedeu-se exérese do tumor com histerectomia total e ooforectomia bilateral. O exame histológico confirmou tratar-se de um cistoadenocarcinoma mucinoso sem invasão de cápsula.Ovarian cancer is the third cause of death among malignant neoplasia in women, and the mucinous cystadenocarcinoma is a malignant neoplasia of the ovarian epithelium, which may achieve great dimensions.

    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

  9. Primary cancers of extrahepatic biliary passages

    International Nuclear Information System (INIS)

    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

    Flat epithelial lesions of the biliary tract cannot be detected by the image analysis, and the diagnosis entirely depends on pathological examination. The biliary tract is often affected by inflammatory conditions, and the resultant changes of the biliary epithelium make it difficult to differentiate them from neoplasia. Thus, the pathological diagnosis of biliary flat epithelial lesions can be challenging. In the biliary tract, there are several forms of intraepithelial neoplasia of the flat type, and biliary intraepithelial neoplasia (BilIN) is known as one of such lesions that represent the multistep cholangiocarcinogenesis. In this article, the diagnostic criteria and the differential diagnosis of biliary flat epithelial lesions, particularly focusing on BilIN, were presented and discussed to provide help to advance clinical and research applications of the BilIN system.

    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.

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. In this article, we briefly review the characteristics of SEMS as well as complications of stent placement. We review the current guidelines for managing malignant and benign biliary obstructions. Recent developments in biliary stenting are also discussed. PMID:26911896

    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)

    @@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.

    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.

    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.

    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.

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

  12. US and RTG guided percutaneous biliary drainage

    International Nuclear Information System (INIS)

    Under combined US and fluoroscopic guidance from anterior approach through left liver lobe a Seldinger technique was used for biliary drainage in 46 patients with nonresectable malignant biliary obstruction. In 9 cases of hilar tumor separating both hepatic ducts a second catheter was inserted through right liver lobe. In 11 cases an internal-external drainage was established. In 3 cases the externally drained bile was recycled by connecting the transhepatic catheter to a percutaneous gastrostomy also performed under US guidance. No severe complications were observed. A described drainage technique provides an effective palliative intervention for advanced biliary malignancies. (author)

  18. Application of percutaneous transhepatic biliary drainage and percutaneous transhepatic insertion of biliary stent in treating malignant biliary obstruction

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical efficacy of percutaneous transhepatic biliary drainage (PTBD) and percutaneous transhepatic insertion of biliary stent (PTIBS) for malignant biliary obstruction. Methods: PTBD or PTIBS were performed in 56 patients with malignant biliary obstruction, which were caused by hepatic carcinoma (n=14), biliary duct carcinoma (n=11), gallbladder carcinoma (n=5), stomach carcinoma accompanied with metastasis of lymph node (n=14), carcinoma of ampulla (n=1) or carcinoma of pancreatic head (n=11). The diagnosis was confirmed by ultrasonography, CT or MRI in all patients. The obstructed site was well identified, including high obstruction in 19 patients and lower obstruction in 37 patients. Based on the imaging findings, suitable interventional procedure was employed. Results: PTBD or PTIBS were performed successfully in all 56 patients, of them PTBD was adopted in 11, PTIBS in 40 and both PTBD and PTIBS in 5. The serum total bilirubin decreased from (295.65 ± 152.86) μmol/L before the procedure to (151.05 ± 107.36) μmol/L after the procedure (P<0.01). Postoperative infection could affect the fading of jaundice (P<0.01), but the location of the obstruction carried no relationship with the fading of jaundice (P=0.063). Conclusion: Both PTBD and PTIBS are safe and effective palliative therapies for malignant biliary obstruction, which can markedly relieve patient of jaundice, improve the quality of life and elongate the survival period.

    Interventional radiologists are often consulted to help identify and treat biliary strictures that can result from a variety of benign etiologies. Mainstays of noninvasive imaging for benign biliary strictures include ultrasound, contrast-enhanced computed tomography and magnetic resonance imaging, magnetic resonance cholangiopancreatography, and computed tomography cholangiography. Endoscopic retrograde cholangiography is the invasive diagnostic procedure of choice, allowing both localization of a stricture and treatment. Percutaneous biliary interventions are reserved for patients who are not candidates for endoscopic retrograde cholangiography (eg, history of distal gastrectomy and biliary-enteric anastomosis to a jejunal roux limb). This review discusses the roles of percutaneous transhepatic cholangiography and biliary drainage in the diagnosis of benign biliary strictures. The methodology for crossing benign biliary strictures, approaches to balloon dilation, management of recalcitrant strictures (ie, large-bore biliary catheters and retrievable covered stents), and the expected outcomes and complications of percutaneous treatment of benign biliary strictures are also addressed.

    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

    AIM: To investigate the total cytochrome P450 (CYP)content, microsomal mixed-function oxidase (MFO)activity, and expression of mRNAs for various CYP isozymes in a simple rat model of reversible obstructive jaundice.METHODS: Obstructive jaundice was created in male rats by causing bile duct obstruction with polyester tape.In another group of rats, bile duct obstruction was followed by internal biliary drainage after releasing the tape.The expression of various CYP isozyme mRNAs was semi-quantitatively assessed by competitive RTPCR.RESULTS: The total CYP content and microsomal MFO activity showed a significant decrease after biliary obstruction, but returned to respective control levels after biliary drainage.A marked reduction in the expression of CYPIA2, 2B1/2, 2Cll, 2E1, 3A1, and 3A2 mRNA was detected during biliary obstruction,while expression increased significantly toward the control level after biliary drainage.Although expression of CYP4A1 mRNA showed no reduction during biliary obstruction, it still increased significantly after biliary drainage.CONCLUSION: These results suggest that not only obstructive jaundice, but also the subsequent internal biliary drainage may affect regulatory medications of the synthesis of individual CYP isozymes differently.

    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.

  1. 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.

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

    A. Vasilescu

    2009-02-01

    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.

    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.

    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

  5. 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

  9. Comparison of three-dimensional negative-contrast CT cholangiopancreatography with three-dimensional MR cholangiopancreatography for the diagnosis of obstructive biliary diseases

    International Nuclear Information System (INIS)

    Purpose: The purpose of our study was to compare three-dimensional (3D) negative-contrast CT cholangiopancreatography (3D-nCTCP) with 3D MR cholangiopancreatography (3D-MRCP) for the diagnosis of obstructive biliary diseases. Materials and methods: 3D-nCTCP and 3D-MRCP were performed on seventy clinically documented obstructive biliary diseases patients. The accuracy of each technique in determining the location and cause of biliary obstruction was evaluated compared with the final clinical diagnoses. Results: Both methods achieved 100% of accuracy in the diagnosis of the presence and location of biliary obstruction, and had a similar sensitivity, specificity, accuracy in differentiating benign from malignant biliary obstruction or calculous from noncalculous biliary obstruction (p > 0.05). At 3D-nCTCP, six patients with stones were misinterpreted as cholangitis (N = 2), papillitis (N = 3), or bile duct adenocarcinoma (N = 1); two metastases were mistaken as acute pancreatitis or pancreatic head carcinomas, and one intrahepatic cholangiocarcinoma was misled as bile duct adenoma. At 3D-MRCP, one small stone, one ampullary adenoma, and one intrahepatic cholangiocarcinoma were mistaken as cholangitis, ampullary stone, and intrahepatic bile duct stone, respectively, and three gallbladder carcinomas and another intrahepatic cholangiocarcinoma were misdiagnosed as hilar cholangiocarcinoma (N = 3) or common hepatic duct stone (N = 1); four metastases were mistaken as pancreatic head carcinomas (N = 3) or distal cholangiocarcinoma (N = 1). The overall accuracy in making specific diagnosis of the cause of biliary obstruction was 87.1% for 3D-nCTCP and 84.3% for 3D-MRCP, respectively, (p > 0.05). Conclusion: 3D-nCTCP has the similar effects as 3D-MRCP for the diagnosis of biliary obstruction and, the location and the cause of biliary obstruction. In view of selected cases contraindications for MRI, 3D-nCTCP is a potential substitute.

  10. GWAS in Primary Biliary Cirrhosis

    Science.gov (United States)

    Gulamhusein, Aliya F.; Juran, Brian D.

    2015-01-01

    Genome wide association studies (GWAS) have been a significant technological advance in our ability to evaluate the genetic architecture of complex diseases such as Primary Biliary Cirrhosis (PBC). To date, six large-scale studies have been performed which identified 27 non-HLA risk loci associated with PBC. The identified risk variants emphasize important disease concepts; namely, that disturbances in immunoregulatory pathways are important in the pathogenesis of PBC and that such perturbations are shared among a diverse number of autoimmune diseases – suggesting the risk architecture may confer a generalized propensity to autoimmunity not necessarily specific to PBC. Furthermore, the impact of non-HLA risk variants, particularly in genes involved with IL-12 signaling, and ethnic variation in conferring susceptibility to PBC have been highlighted. While GWAS have been a critical stepping-stone in understanding common genetic variation contributing to PBC, limitations pertaining to power, sample availability, and strong linkage disequilibrium across genes have left us with an incomplete understanding of the genetic underpinnings of disease pathogenesis. Future efforts to gain insight into this missing heritability, the genetic variation that contributes to important disease outcomes and the functional consequences of associated variants will be critical if practical clinical translation is to be realized.

    2006-06-01

    Full Text Available Biliary atresia is the most common cause of pathologic jaundice in young infants andresults from the obstruction of the extrahepatic bile ducts by an inflammatory and fibroobliterativeprocess. Although the pathogenesis of the disease is multifactorial, recentpatient- and animal-based studies began deciphering the molecular pathways involved in biliaryinjury and duct obstruction. Using large-scale genomics and immunostaining of liversfrom children with biliary atresia, investigators have discovered unique molecular signaturesof dominant proinflammatory cytokines at the time of diagnosis. To study hypotheses generatedfrom these patient-based studies, the anatomical and inflammatory profiles of a mousemodel of rotavirus-induced biliary atresia were analyzed and found to share striking similaritieswith the human profiles. Then, using these mice in mechanistic studies, interferongamma(IFNγ has been shown to regulate the biliary tropism of lymphocytes to the biliarysystem, and to play a critical role in the inflammatory obstruction of extrahepatic bile ducts.The ability to combine human studies with a laboratory model of neonatal biliary injury andobstruction opens a new era of opportunities to advance the field of biliary atresia, and todevelop new therapeutic strategies to improve long-term outcome with the native liver ofchildren with biliary atresia.

    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 Tc-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 Tc-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 Tc-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. PMID:26559297

    Full Text Available Bacterial infections of the biliary tract are often considered to be an important cause of acute cholangitis. Viral infections of the biliary tract however, are very often mistaken as viral hepatitis. This article highlights various viral causes of common biliary tract infections. Viral cholangitis is both less common and less discussed than viral hepatitis. Hepatotropic viruses (A, B, C, and E are generally regarded as hepatocellular pathogens, yet cholangitic manifestations are now well described in association with these diseases. Systemic viral diseases also lead to cholangitis in varying proportion to hepatitis. Human immunodeficiency virus is associated with protean hepatic complications, including cholangitis due to several causes. Other systemic viruses, most notably those of the herpes virus family, also cause hepatic disease including cholangitis and possibly ductopenia in both immunocompromised and immunocompetent patients.

    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.

  19. Biliary obstruction: Helical computed tomography cholangiography evaluation

    International Nuclear Information System (INIS)

    Helical computed tomography cholangiography (HCTC) takes advantage of the improvement in the quality of multiplanar and three-dimensional reconstructions resulting from the volumetric acquisition of data achieved with helical computed tomography and the indirect opacification of the bile ducts provided by cholangiographic contrast media. 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

    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.

  1. Role of hepatobiliary scintigraphy in biliary ascariasis

    International Nuclear Information System (INIS)

    Following the introduction of immunodiacetic acid (IDA) compounds labelled with 99Tcm, hepatobiliary scintigraphy has successfully been used to identify a variety of hepatobiliary pathologies. This study deals with the scintigraphic findings in patients having involvement of the hepatobiliary system with ascariasis. Patients clinically suspected of having hepatobiliary pathology were routinely sent for radionuclide evaluation of the hepatobiliary system. 99Tcm HIDA, EHIDA or BULLIDA was injected under the gamma camera and one min frames were collected for 40 min over the abdominal region using an on-line computer. After the sequential study was over, if the gallbladder was not visualized, late pictures were taken until the gallbladder was seen or for 4 hours, whichever was earlier. When the gallbladder was visualized, post-fatty-meal images were made for visual analysis and time/activity curves were generated over regions of interest for further evaluation. Patients having total or partial subhepatic biliary channel obstruction with or without dilatation of intrahepatic ducts were subjected to endoscopic retrograde cholangio-pancreatography (ERCP) within the next two to three days. Out of 360 patients thus evaluated, 84 (23%) showed partial, total or near total subhepatic obstruction. In 55 cases the whole biliary tree was dilated; in 17 cases the left hepatic duct and the common bile duct (CBD); in seven cases the left hepatic duct alone, and in five cases the CBD alone. ERCP findings were concurrent in most cases. However, in 13 cases no abnormality of the biliary tree could be detected by ERCP, although worms were found in the duodenum. In 28 cases single or multiple worms were found inside the hepatobiliary channel. Video recordings of the ERCP revealed in some cases that the worms were moving in and out of the biliary channel. In 41 cases of proven biliary ascariasis, scintigraphic finding was indicative in all cases. Hepatobiliary scintigraphy appears to be a

  2. Usefulness of magnetic resonance cholangiography in the diagnosis of biliary tract lesions in patients with suspected complication following cholecystectomy

    International Nuclear Information System (INIS)

    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.

    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

    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)

    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.

    Full Text Available Ascariasis is one of the most common helminthic diseases in humans, occurring mostly in countries with low standards of public health and hygiene, thereby making ascariasis highly endemic in developing countries. In endemic areas, 30% of adults and 60–70% of children harbour the adult worm. Biliary ascariasis is a rare cause of obstructive jaundice. Conventional management involves endoscopic extraction of worm. We are reporting a rare case of ascaris which induced extrahepatic biliary obstruction in a young male who presented with acute cholangitis. The ascaris was removed by laparoscopic exploration of the common bile duct. Postoperative period was uneventful.

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.)

  9. PERCUTAENOUS BILIARY DRAINAGE IN MALIGNANT OBSTRUCTIVE JAUNDICE

    2008-10-01

    Full Text Available In patients with malignant obstructive jaundice for whom surgery is not indicated the treatment of choice is palliative biliary drainage either endoscopic or percutaneous. We present our experience with percutaneous drainage. Although percutaneous placement of an endoprosthesis is preferred, the patients are seldom candidates for such a procedure because of locally advanced disease, and even when successful survival is not significantly affected but merely the patients’ quality of life. For this patients internal-external catheter drainage or external biliary drainage might still be of help provided that a proper care and periodical catheter change is ensured.

    LENUS (Irish Health Repository)

    Hennessey, Derek B

    2012-02-01

    Biliary cystadenomas are benign but potentially malignant cystic neoplasms, which classically contain mesenchymal stroma similar to ovarian tissue. We report a case of an extra-hepatic biliary cystadenoma with mesenchymal stroma along with a discussion of current pathological opinion. CASE PRESENTATION: A 54-year-old female presented with abdominal pain, abnormal liver function tests and a mass on ultrasound. Computerized Tomography identified a complex multi-locular cyst in the common hepatic duct. Radical excision of the lesion and a Roux-en-Y loop bilio-enteric anastomosis was performed. Histology confirmed the presence of a benign biliary cystadenoma with ovarian type stroma. CONCLUSION: Biliary cystadenomas classically contain mesenchymal stroma similar to ovarian tissue. It now appears that cystadenomas without mesenchymal stroma appear to be more akin to similar cystic lesions of the pancreas, and may represent a dissimilar neoplasm. Therefore, malignant transformation can occur, so complete excision is recommended.

    Introduction. The usual indication for a biliary-digestive bypass is the obstruction by a benign or a malignant stricture which can occur at the biliary- pancreatic confluence. Benign strictures mostly occur in the distal bile duct as a result of stones or chronic pancreatitis. Malignant obstructions involve mostly the distal end as a result of a ductal adenocarcinoma of the head of the pancreas, the ampulla of Vater and cholangiocarcinoma and can be virtually impossible to distinguish from e...

  15. Radiological biliary tract diagnosis after cholecystectomy

    Fifty-three patients with biliary symptoms were studied at least four years after cholecystectomy by isotope techniques. There was a highly significant correlation between symptoms and disturbances of bile flow, such as dyskinesia or obstruction. There was no correlation with serum enzyme levels such as gamma-GT, alkaline phosphatase, bilirubin or transaminases. Measurements of the diameter of the bile duct on cholangiograms provided no evidence of obstruction up to 15 mm, although a diameter in excess of 10 mm. made obstruction likely. The upper value for 'normal' bile flow derived from hilar flow curves of patients without dyskinesia showed a half value period of 27.5 minutes. The disturbances of flow demonstrated by isotope methods in the presence of typical symptoms, and without other pathological findings, indicate a pre-clinical stage of a partly compensated biliodynamic insufficiency. Where there is no morphological evidence of biliary obstruction, one must assume inflammatory changes round the papilla of Vater; these are frequent even in normal biliary tracts and almost always present after cholecystectomy. Quantitative hepato-biliary scintigraphy is the most reliable method for objective measurement of disturbances of bile flow and make it possible to avoid the vague diagnosis of 'postcholecystectomy syndrome'.

    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.

  17. Extrahepatic biliary obstruction; postoperative morbidity and mortality

    International Nuclear Information System (INIS)

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

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

    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

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.

    The outcome of combination of biliary tract drainage with other adjunctive therapies for unresectable malignant biliary tract stricture was evaluated in the 135 patients with known outcome treated in this unit between June, 1986 and May, 1998. Compared to percutaneous transhepatic drainage, transpapillary drainage significantly shortened the jaundice reduction period but yielded a slightly inferior technical success rate. The efficacy of transpapillary drainage for jaundice was extremely poor in cases of stricture in the upper part of the biliary tract. A histological comparison of bile duct lumen after various adjunctive therapies showed that intraluminal therapy was much more effective than extracorporeal radiation. Adjunctive therapies significantly increased the survival period in patients with cholangiocarcinoma but they were less effective in patients with pancreatic carcinoma and not effective at all in patients with gallbladder carcinoma. Intraluminal therapy markedly prolonged the internal fistula maintenance period and was effective in improving the quality of life in patients with superior bile duct stricture at multiple sites. The hospital stay was significantly longer in patients who received adjunctive therapy than in those who received biliary tract drainage alone. This finding suggests that adjunctive therapy should not be conducted if it is not expected to result in an increase in the survival period that compensates for disadvantages of a prolonged hospital stay. In conclusion, in the treatment of inoperable malignant biliary tract stricture, adjunctive therapy should be conducted whenever possible in combination with percutaneous biliary tract drainage, which enable intraluminal therapy, in patients with cholangiocarcinoma. However, biliary tract drainage alone is recommended in patients with pancreatic and gallbladder carcinoma because adjunctive therapy does not seem to be effective. A transpapillary approach is recommended for pancreatic

    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.

    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.

    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.

    Percutaneous Transhepatic Biliary Catheterization is commonly employed in the diagnosis and management of obstructive jaundice associated with malignant lesions. Tumor manipulation as an effort to obtain a histological diagnosis or to establish short or long-term internal-external biliary drainage is liable to disseminate the malignancy along the catheter tract. Two cases of malignant seeding of the catheter tract after biliary drainage have been observed.

    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

  9. 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)

  10. 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

    Cholangiocarcinoma is a rare cancer originating from the neoplastic transformation of the epithelial cells (i.e. cholangiocytes) that line the biliary tract. The prognosis for patients with cholangiocarcinoma is grim due to lack of viable treatment options. The increase in world-wide incidence and mortality from cholangiocarcinoma highlights the importance of understanding the intracellular mechanisms that trigger the neoplastic transformation of cholangiocytes and the growth of biliary cancers. The purpose of the following review is to address what has been learned over the past decade concerning the molecular basis of cholangiocarcinogenesis. The material presented is divided into two sections: (1) mechanisms regulating neoplastic transformation of cholangiocytes; and (2) factors regulating cholangiocarcinoma growth. An understanding of the growth regulatory mechanisms of cholangiocarcinoma will lead to the identification of therapeutic targets for this devastating cancer. PMID:18494047

  14. Technical problems during percutaneous transhepatic biliary drainage

    International Nuclear Information System (INIS)

    Technical problems are repeatedly encountered during percutaneous transhepatic drainage by catheter or endo-prosthesis which are caused by the position, extent and tightness of the stenosis in the biliary ducts. All means of overcoming these problems must be used, otherwise technical failure or complications become inevitable. The methods to be adopted if catheters break and endo-prostheses become displaced or occluded, and for haemorrhage, are described, as well as methods for draining multiple, proximal or intrahepatic stenoses. This is based on an experience with 74 patients on whom 130 drainage procedures have been perforemd (80 catheters, 50 endo-prostheses. All complications and mortality (five patients, 3.8%) were due to problems which could not be solved. Internal biliary drainage by means of an endoprosthesis is markedly superior to catheter drainage. (orig.)

  15. Arterial Complications of Percutaneous Transhepatic Biliary Drainage

    International Nuclear Information System (INIS)

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

    Metastasis of colon adenocarcinoma is commonly found in the lung, liver, or peritoneum. Common bile duct (CBD) tumors related to adenomas from familial adenomatous polyposis metastasizing from outside of the gastrointestinal tract have been reported. We report a case of biliary colic due to metastatic colon adenocarcinoma to the CBD. Obstructive jaundice with signs of acalculous cholecystitis on imaging in a patient with a history of colon cancer should raise suspicion for metastasis to CBD. PMID:27144209

    Ischemic type biliary lesion (ITBL) is a rare and relative late complication after orthotopic liver transplantation. ITBL is characterized by bile duct necrosis leading to alternations of the ductal lumen. The paper reports a case of 52-year-old women with ITBL syndrome after orthotopic liver transplantation. The clinical picture and results of direct cholangiography, MRCP and ultrasound imaging are discussed. Ischemic type biliary lesion is defined as non-ischemic destruction of the graft's biliary tree after liver transplantation. The diagnosis of ITBL syndrome is based upon results of cholangiography and ultrasound imaging with a characteristic picture of the biliary tree with normal flow in the hepatic artery. (author)

    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.

    Septic shock leading to multi-organ failure is not uncommon. Early diagnosis to confirm the source is the distinctive attribute of sepsis management guidelines. Cholangitis as the source of sepsis can become a diagnostic dilemma in patients who have had cholecystectomy in the past. CT abdomen should be the investigation of choice in this group of patients. This report describes two postcholecystectomy patients who presented with septic shock secondary to biliary stones. The source of septic shock in both patients were biliary stones was confirmed with abdominal CT. Ultrasound abdomen failed to report biliary stones in these patients. Both improved on percutaneous transhepatic biliary drainage. PMID:26522207

    A captive 3-mo-old white African lion (Panthera leo) presented with clinical signs of acute pain and a distended abdomen. Despite emergency treatment, the lion died a few hours after presentation. Postmortem examination revealed gross changes in the liver, spleen, and lungs and an anomalous cystic structure in the bile duct. Histologic examination identified severe generalized multifocal to coalescent necrotizing and neutrophilic hepatitis, neutrophilic splenitis, and mild interstitial pneumonia, consistent with bacterial septicemia. The abnormal biliary structures resembled biliary cystadenoma. However, due to the age of the animal, they were presumed to be congenital in origin. Biliary tract anomalies and cystadenomas have been reported previously in adult lions, and this case suggests that at least some of these examples may have a congenital basis. It is unclear whether the lesion was an underlying factor in the development of hepatitis. PMID:23272363

    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. PMID:26981114

  8. Excretion of biliary compounds during intrauterine life

    In adults, the hepatobiliary system, together with thekidney, constitute the main routes for the eliminationof several endogenous and xenobiotic compounds intobile and urine, respectively. However, during intrauterinelife the biliary route of excretion for cholephiliccompounds, such as bile acids and biliary pigments, isvery 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.

We studied 198 cases (11% of biliary ascariasis out of 1,800 patients of worm infestation from December 2001 to December 2004 in the age group of 4-15 years. In our study, we found biliary ascariasis to be more common in female children, and most common clinical presentation was biliary colic in 143 patients, cholangitis in 28, cholecystitis in 15, liver abscess 7, pancreatitis 4 and postoperative worm infestation in 1 patient. Ultrasonography of abdomen was the diagnostic tool of choice with hundred percent results. Most of the patients were managed conservatively. ERCP was not done in children because of need of general anesthesia and difficulty in performing the procedure. Surgical intervention was required in 23 patients (cholecystectomy with CBD exploration in 5, choledochotomy alone in 13, drainage of liver abscess in 3, choledochoduodenostomy in 1 and peritoneal lavage in 1.

    Forty one patients gallbladder and bile duct diseases were studied clinically and sonographically. Twenty nine (seventy one percent) patients were distributed between age forty to fifty nine and male to female ratio was 1 : 1.4. The order of frequency of biliary tract disease was cholelithiasis, acclculous cholecystitis, CBD stone and CBD cancer. Sonographic findings of cholelithiasis were strong echo with posterior shadowing, faint internal echoes without shadowing, gallbladder wall thickening and anechoicity of the gallbladder wall. Instead of small proportion of gallbladder distension and wall anechoicity, faint internal echoes without shadowing were seen in ten of nineteen cases of choleithiasis. On choledocholithiasis, meniscus sign at the junction of the stone and gallbladder wall was identified in most cases and was helpful to differentiation stone from malignancy. The degree of CBD dilatation was more severe in malignancy than in CBD stone and ascaris in CBD. Sonographic examination was useful in detection of gallbladder and biliary tree pathology and the cause of biliary tract obstruction could be identified.

    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 cholangiography, but nowadays it emerges as a powerful therapeutic 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 retrograde 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 transpapillary, 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.

    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.

    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

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

    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.

    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.)

    AIM: To evaluate the utility of local tumor therapy combined with percutaneous transhepatic biliary drainage (PTBD) for malignant obstructive biliary disease.METHODS: A total of 233 patients with malignant biliary obstruction were treated in our hospital with PTBD by placement of metallic stents and/or plastic tubes. After PTBD, 49 patients Accepted: brachytherapy or extraradiation therapy or arterial infusion chemotherapy. The patients were followed up with clinical and radiographic evaluation. 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.

    Full Text Available Several parasites infest liver or biliary tree, either during their maturation stages or as adult worms. Bile iry tree parasites may cause pancreatitis, cholecystitis, biliary tree obstruction, recurrent cholangitis, biliary tree strictures and some may lead to cholangiocarcinoma. This review discusses the hepatobiliary parasites, and shows our experience in diagnosis and management of these parasites. Ultrasonography of the liver is diagnostic in schistosomiasis, hydatid cysts, amebic liver abscess, ascariasis and other biliary tree parasites showing bile duct dilatation. Percutaneous aspiration under ultrasonography guidance of hydatid liver cysts or amebic abscess are effective measures in management. Endoscopic retrograde cholangiopancreatography (ERCP is safe and effective in diagnosis and management of biliary tree parasites.

    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. 

  18. 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

    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.

    The etiologic and pathogenic factors contributing to primary biliary cirrhosis (PBC) development, progression, response to treatment, and outcome remain a mystery. Recognition of the genomic regions harboring risk factors is hindered by the rarity and late onset of PBC. Recent advancements in genomics hold promise for understanding, prevention, and therapy of PBC. Large registries and biospecimen repositories of patients who have PBC, their family members, and controls are needed. Haplotype mapping-based association studies are necessary for defining genetic predisposition. Experimental data will provide the means for fine mapping studies, resequencing efforts, functional experimentation, and elucidation of gene-environment and gene-gene interaction. PMID:18456185

  6. 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)

    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.

  8. Malignant biliary obstruction: From palliation to treatment

    Boulay, Brian R; Birg, Aleksandr

    2016-01-01

    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

  10. 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

  11. 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.

    2015-09-01

    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

  20. 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

  1. Balloon dilatation of intrahepatic biliary strictures in liver transplantation

    International Nuclear Information System (INIS)

    Objective: To evaluate the efficacy of balloon dilatation in the treatment of intrahepatic biliary strictures in patients with liver transplantation. Methods: Of the 100 patients with liver transplantation, 16 patients had intrahepatic biliary strictures and received balloon dilatation treatment. Results: Initial technical balloon dilatation was successful in 14 caes but failed in 2 cases. There were no procedure-related complications. 4 restenosis occurred and they were treated with repeated balloon dilatation treatment. Conclusion: Balloon dilatation represented an effective and relatively safe treatment for biliary stricture in liver transplant recipients. For restenosis, balloon dilatation was also an effective treatment

  2. Biliary excretion of intravenous [14C] omeprazole in humans

    International Nuclear Information System (INIS)

    We have studied the biliary excretion of [14C] omeprazole in humans. The study was performed in eight healthy subjects and the technique used was based on multiple marker dilution principles with double-lumen tubes placed in both the stomach and intestine. The results obtained show a 16% biliary excretion of [14C] omeprazole. These data suggest a minimal spillover of omeprazole from the gastric mucosa into the gastric lumen in humans. The results also agree with previous data of the fecal recovery of radiolabeled omeprazole that suggest that the fecal excretion of intravenous omeprazole in humans is entirely accounted for by biliary excretion

    Full Text Available Cystic diseases of liver are recognized in infancy and childhood initially. Cystic diseases of liver and biliary tract are choledocal cysts, autosomal recessive and autosomal dominant polycystic kidney disease, congenital hepatic fibrosis and Caroli disease (cystic dilatation of intrahepatic bile ducts. Choledochal cysts and Caroli disease do not allow biliary flow, cause chronic or obstructive cholestasis and progressive liver disease. In congenital hepatic fibrosis and polycystic kidney disease there is cystic formations at terminal interlobular bile ducts, but cholestasis is not seen. They don’t cause liver and biliary tract functional disturbances. (Turk Arch Ped 2008; 43: 40-5

    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).

The authors recently saw three patients with cholangiocarcinoma in whom metastatic seeding of the peritoneal serosa was identified some months after initial percutaneous transhepatic biliary drainage. Although no tumor was found along the hepatic tract of the biliary drainage catheters to implicate the drainage tubes as the direct source of peritoneal spread, the occurrence of this rare type of metastasis of cholangiocarcinoma in patients with potential access of tumor cells to the peritoneal cavity via the catheter tracts does suggest such a relation.

    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.

  9. 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)

  10. Biliary pressure: manometric and perfusion studies at percutaneous transhepatic cholangiography and percutaneous biliary drainage

    International Nuclear Information System (INIS)

    Manometric pressure recordings were attempted during percutaneous transhepatic cholangiography (PTC) and after percutaneous biliary drainage (PBD) in 203 cases. Successful readings were achieved at PTC in 85% (104/122) of patients. Pressure measurements were also obtained through 56 biliary drainage catheters, and controlled perfusion challenges were performed in 12 patients (on 18 occasions). Documentation of the occasionally poor correlation between the caliber of ducts and the degree of obstruction (i.e., pressure) was shown, and it was suggested that very high pressures may be predictive of a bile leak after PTC. Adequacy of percutaneous drainage and stricture dilatation were further assessed with these manometric techniques. Pressure and perfusion data aided in detecting and determining the significance of the nondilated obstructed duct, the dilated nonobstructed ductal system, and subtle distal ductal strictures. The knowledge obtained from percutaneous pressure recordings may help to determine appropriate therapy

    We report our experience with 4 cases of cystic dilatation of intrahepatic bile ducts following hepatic portoenterostomy for biliary atresia. Two of the cases did not achieve satisfactory bile excretion and all four cases developed recurrent cholangitis after hepatic portoenterostomy. The attacks of cholangitis seemed to be associated with the presence of intrahepatic cysts. Although one case resulted in death from hepatic failure, three other cases are now outpatients. Patients who develop recurrent cholangitis following hepatic portoenterostomy, should be examined to exclude the presence of intrahepatic biliary cysts. Ultrasonography, computed tomography and percutaneous transhepatic cholangiography were all effective in detecting cysts and provided valuable information for planning treatment. Percutaneous transhepatic or surgical drainage of the bile ducts was effective in reducing jaundice, and recurrent cholangitis. (orig.).

  12. Ischemic-type biliary lesion without hepatic artery occlusion after liver transplantation: early diagnosis of cholangiography

    International Nuclear Information System (INIS)

    Objective: To evaluate the value of cholangiography for early diagnosis of ischemic-type biliary lesions(ITBL) after liver transplantation. Methods: Two hundred and fifty-three patients with liver transplantaion between Jan 2004 and Oct 2006 were recruited. Initial cholangiography was compared with terminal cholangiography to evaluate the value of initial cholangiography of ITBL. The t test, Chi-square test, sum rank test were used for statistics. Results: Based on initial cholangiography, 189 patients were diagnosed with normal appearance, while 64 patients were diagnosed with abnormal appearance. The abnormal initial cholangiography appearances included poor filling in 33 patients and irregularity in 31 patients. Based on terminal cholangiography, 199 patients were diagnosed with normal appearance and 54 patients with ITBL. In patients with abnormal initial cholangiography, ITBL was occurred in 39 of 64 patients including 10 of 33 poor filling patients and 29 of 31 irregularity patients. In patients with normal initial appearance, ITBL was only occurred in 15 of 189 patients. The abnormal initial cholangiography was associated with ITBL significantly (χ2=79.999, P=0.000, r=0.490). Initial cholangiography had an overall sensitivity of 72.22%, and specificity of 87.44%, with positive and negative predictive values of 60.94% and 92.06%, respectively. The abnormal initial cholangiography was a risk factor of ITBL by logistic regression analyses (OR=15.193, P=0.000). Conclusion: The abnormal initial cholangiography is associated with ITBL. Initial cholangiography, especially minimal irregular of intrahepatic biliary tract, is a sensitive and specific method for the detection of ITBL after liver transplantation. (authors)

  13. 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

  14. Gianturco metallic biliary stent in malignant biliary obstruction: results of follow-up in dead patients

    International Nuclear Information System (INIS)

    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

    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.

    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.

    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.

  19. The effect of morphine on biliary dynamics

    International Nuclear Information System (INIS)

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

    2014-08-01

    The etiology of the autoimmune liver disease primary biliary cirrhosis (PBC) remains largely unresolved, owing in large part to the complexity of interaction between environmental and genetic contributors underlying disease development. Observations of disease clustering, differences in geographical prevalence, and seasonality of diagnosis rates suggest the environmental component to PBC is strong, and epidemiological studies have consistently found cigarette smoking and history of urinary tract infection to be associated with PBC. Current evidence implicates molecular mimicry as a primary mechanism driving loss of tolerance and subsequent autoimmunity in PBC, yet other environmentally influenced disease processes are likely to be involved in pathogenesis. In this review, the authors provide an overview of current findings and touch on potential mechanisms behind the environmental component of PBC. PMID:25057950

    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 Purpose: Percutaneous transhepatic primary biliary stenting (PS is an alternative to the widely used staged procedure (secondary biliary stenting, SS for treating obstructive jaundice in cancer patients. To evaluate the efficacy and safety of PS and SS, a retrospective analysis was carried out. Materials and Methods: The percutaneous biliary stenting procedures performed between January 2000 and December 2007 at one hepatobiliary center were retrospectively analyzed, comparing the technical success rates, complications, and length of hospitalization of the two procedures. Of 61 patients (mean age 65.5 ± 13.1 years; range 31.1-92.7 years suffering from obstructive jaundice caused by primary or metastatic tumors, 30 received PS and 31 received SS. The groups were comparable in the anatomical level of the obstruction, stent configuration, or the concurrent presence of cholangitis. Placement of metallic stents required one session for patients in the PS group and an average of 2.6 ± 1.1 sessions for patients in the SS group. Results: The overall technical success rate was 98.4% with 1 (1/61 failed approach to transcend the occlusion in the SS group. The rate of minor complications was 10% in the PS group and 6.5% in the SS group. The corresponding rates of major complications were 23.3% and 54.8%, respectively. SS patients had a higher rate of complications in general ( P < 0.05, as well as a higher rate of severe complications in particular ( P < 0.05. Procedural mortality was 0% for both the groups. The mean overall length of hospitalization was 7.7 ± 9.6 days for PS and 20.6 ± 19.6 days for SS ( P < 0.001. Conclusion: Primary percutaneous biliary stenting of malignant biliary obstructions is as efficacious and safer than a staged procedure with secondary stenting. By virtue of requiring shorter hospital stays, primary stenting is likely to be more cost-effective.

  3. 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.

    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.

    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.

  10. Eclectic use of cholecystostomy in biliary tract procedures

    International Nuclear Information System (INIS)

    Twenty-seven patients underwent percutaneous aspiration or catheterization of gallbladder for the diagnosis or treatment of biliary tract disease, including 12 cases of cholecystitis, nine malignancies, two cases of choledocholithiasis, and one case of biliary structure. In three patients the cholangiograms were normal. Cholestostomy catheters were placed in 25 patients, including those with normal cholangiograms; the catheters were withdrawn from these patients after the procedure. In all other patients with obstruction the catheters were left in place for drainage, stone chemolysis, or assistance with ductal opacification during percutaneous biliary dilation. There were two minor and no major complications. In addition to its uses in gallbladder disease, percutaneous cholecystostomy is a safe, less painful alternative to percutaneous transhepatic cholangiography. In conjunction with transhepatic drainage for malignancy, it allows control of biliary opacification and optimal selection of the site of ductal puncture

  14. LAPAROSCOPIC ANATOMY OF THE EXTRAHEPATIC BILIARY TRACT

    Directory of Open Access Journals (Sweden)

    E. Târcoveanu

    2005-01-01

    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

  15. 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.)

    1995-05-01

    We have previously reported an association of impaired S-oxidation with primary biliary cirrhosis. In order to confirm and further define this relationship, we retested S-oxidation capacity via three metabolic pathways and sulphation capacity via a fourth pathway. Metabolism of S-carboxymethyl-L-cysteine is polymorphic -20% of healthy individuals being poor S-oxidisers. We found 26% with primary biliary cirrhosis were poor S-oxidisers, compared with 36% with other liver disease and 25% of healthy controls. Differences were not statistically significant. S-oxidation of ranitidine is dependent upon flavin mono-oxygenases. We showed a non-significant trend toward less S-oxide in primary biliary cirrhosis and other liver disease, compared with healthy controls, with no significant difference between disease groups. Conversion of cysteine to sulphate depends predominantly on cysteine dioxygenase. Impaired activity may be reflected by decreased plasma sulphate and elevated cysteine. We found that the plasma cysteine: sulphate ratio was significantly elevated not only in primary biliary cirrhosis (p < 0.0001), but also in other liver disease (p < 0.0001), compared with healthy individuals. Sulphation capacity was studied by analysing paracetamol metabolism. Paracetamol sulphate and sulphate: glucuronide ratio were reduced in primary biliary cirrhosis compared with normal individuals, (p < 0.05). A trend towards less sulphate in primary biliary cirrhosis compared other liver disease was not significant (p = 0.42). We conclude that although sulphation and some sulphoxidation pathways are impaired in primary biliary cirrhosis, we can currently find no evidence to substantiate the hypothesis that primary biliary cirrhosis is a disease specifically associated with poor S-oxidation, as assessed via these metabolic pathways.

    Cholangiocarcinoma often is diagnosed at an advanced stage. Thus, it is necessary to establish sensitive screening methods that would allow cholangiocarcinoma and preferably its precursor lesion [biliary intraepithelial neoplasia (BilIN)] to be detected. We sought to clarify the usefulness of heat shock protein (HSP) 27 and HSP70 as biomarkers of cholangiocarcinoma and have used immunohistochemical analyses of hepatolithiatic livers to characterize HSP27 and HSP70 expression during the multistep cholangiocarcinogenesis process. HSP27 and HSP70 were measured in serum and bile samples via enzyme-linked immunosorbent assay. In hepatolithiatic tissue, the expression of HSP27 and HSP70 was increased in BilIN as well as in invasive cholangiocarcinoma. The serum levels of HSP27 and HSP70 were not significantly different between the hepatolithiatic patients with and without cholangiocarcinoma. In contrast, the bile levels of HSP27 and HSP70 were increased significantly in the patients with cholangiocarcinoma compared with those in the patients with lithiasis. Combining the measurements of the bile levels of HSP27 and HSP70 increased their usefulness as biomarkers, and the sum (HSP27 + HSP70) yielded the best sensitivity (90%) and specificity (100%). These results suggest that HSP27 and HSP70 could be used as biliary biomarkers for the detection of cholangiocarcinoma including BilIN. PMID:22051775

    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...

    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

    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.

  19. 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

  20. 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

  1. Management issues in post living donor liver transplant biliary strictures.

    Biliary complications are common after living donor liver transplant (LDLT) although with advancements in surgical understanding and techniques, the incidence is decreasing. Biliary strictures are more common than leaks. Endoscopic retrograde cholangiopancreatography (ERCP) is the first line modality of treatment of post LDLT biliary strictures with a technical success rate of 75%-80%. Most of ERCP failures are successfully treated by percutaneous transhepatic biliary drainage (PTBD) and rendezvous technique. A minority of patients may require surgical correction. ERCP for these strictures is technically more challenging than routine as well post deceased donor strictures. Biliary strictures may increase the morbidity of a liver transplant recipient, but the mortality is similar to those with or without strictures. Post transplant strictures are short segment and soft, requiring only a few session of ERCP before complete dilatation. Long-term outcome of patients with biliary stricture is similar to those without stricture. With the introduction of new generation cholangioscopes, ERCP success rate may increase, obviating the need for PTBD and surgery in these patients. PMID:27057304

    A 59-year-old man with a known central hepatocellular carcinoma (HCC) underwent a trans-arterial-chemo-embolization (TACE) and a post-TACE percutaneous radiofrequency ablation (PRFA). Two months after the PRFA, the patient presented jaundice and an abdominal computed tomography was obtained. An arterial enhancing mass adjacent to the ablated necrotic lesion with a continuously coexisting mass inside the right hepatic duct, suggestive of a HCC recurrence with a direct extension to the biliary tract was found. Finally a biliary tumor obstruction has been developed and a percutaneous transhepatic biliary drainage was performed. This case of biliary obstruction caused by directly invaded recurred HCC after PRFA will be reported because of its rare occurrence.

    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.

    The aim of our study was to determine the role of MR cholangiography (MRC) and hepatobiliary scintigraphy (HBS) in the assessemtn of recurrent bile duct obstruction after biliary surgery. Twenty-three patients (15 men and 8 women: mean age 49.8) with post-biliary operation state (16 biliary-enteric anastomoses and seven cholecystectomy) underwent a total of 28 MRC and 28 HBS using Tc-99m DISIDA within 3 days of each other. Interval between surgery and MRC or HBS ranged from 2 wk to 15 yr (median: 14 mon). MRC and HBS were analyzed for the presence of bile duct obstruction. The final diagnoses were cofirmed by percutaneous transhepatic biliary drainage or surgical operation in 11 of 28 cases and by the follow-up clinical course in the rests. Of 14 instances with bile duct obstruction (13 intrahepatic bile duct obstruction and 1 common bile duct obstruction), HBS showed complete intrahepatic bile duct (IHD) obstruction in 7, incomplete IHD obstruction in 5, parenchymal dysfuction in 1, and IHD dilation without obstructon in 1, resulting in sensitivity of 86% (12/14). MRC showed stone in 6, stricture in 4, IHD dilatation in 3, and normal in 1. The sensitivity of MRC was 71% (10/14). Fourteen instances were without obstruction. HBS showed no evidence of obstruction in all 14 instances (specificity 100%). However, stricture on MRC was found in 4 instances, resulting in specificity of 71% (10/14). HBS is useful in the diagnosis of recurrent bile duct obstruction after surgery. MRC is a useful modality for assessing the diagnosis of obstruction itself as well as the cause and location of bile duct obstruction. However, the specificity of MRC appears to be lower because of possible overestimation of stricture.

    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.

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

    Full Text Available Ascariasis is a common infection in many developing countries. The prevalence of ascariasis is related to poverty, poor hygienic and sanitary conditions. The adult form of Ascaris lumbricoides usually resides in the human intestinal lumen (more frequently in the jejunum and middle ileum and does not cause symptoms. However, it can occasionally cause severe complications such as intestinal obstruction or perforation peritonitis. Its migration into the biliary tract is not uncommon but gallbladder involvement is very rare. Abdominal ultrasonography is essential to detect the presence of this parasite. In this article, we describe the radiologic findings, clinical manifestations and successful medical treatment of a patient with gallbladder ascariasis diagnosed in an emergency setting.

    To analyze the survival period, prognostic factors and complications of patients having under gone high-dose-rate intraluminal brachytherapy (HDR-ILB) as a salvage radiation therapy, while having a catheter, for percutaneous transhepatic biliary drainage (PTBD), inserted due to biliary obstruction caused by a secondary malignant biliary tumor. A retrospective study was performed on 24 patients having undergone HDR-ILB, with PTBD catheter insertion, between December 1992 and August 2001, Their median age was 58.5, ranging from 35 to 82 years. The primary cancer site were the stomach, gallbladder, liver, pancreas and the colon, with 12, 6, 3, 2 and 1 cases, respectively. Eighteen patients were treated with external beam radiation therapy and HDR-ILB, while six were treated with HDR-ILB only. The total external beam, and brachytherapy radiations dose were 30-61.2 and 9-30 Gy, with median doses of 50 and 15 Gy, respectively. Of the 24 patients analyzed, 22 died during the follow-up period, with a median survival of 7.3 months. The 6 and 12 months survival rates were 54.2 (13 patients) and 20.8% (5 patients), respectively. The median survivals for stomach and gallbladder cancers were 7.8 and 10.2 months, respectively. According to the univariate analysis, a significant factor affecting survival of over one year was the total radiation dose (over 50 Gy) (0=0.0200), with all the patients surviving more than one year had been irradiated with more than 50 Gy. The acute side effects during the radiation therapy were managed with conservative treatment. During the follow-up period, 5 patients showed symptoms of cholangitis due to the radiation therapy. An extension to the survival of those patients treated with HDR-ILB is suggested compared to the median historical survival of those patients treated with external biliary drainage. A boost radiation dose could be effectively given, by performing HDR-ILB, which is a prognostic factor. In addition, the acute complications of

    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

    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.

  1. Prognostic factors after percutaneous transhepatic biliary drainage

    International Nuclear Information System (INIS)

    The authors reviewed the clinical charts and the radiographic files of 93 patients with obsructive jaundice -in 86 cases due to neoplasms -treated with PTBD. The test of differences from survival curves was used to identify the clinical parameters predictive of short survival after PTBD. The difference in survival curves was significant relative to serum indirect bilirubin (cut point: 7.6 mg%), to serum cholinesterase (cut point: 1290 mU/ml), to white blood cells counts (cut point: 8600/mm3), to blood urea nitrogen (BUN) levels (cut point: 60 mg%). Because of the market negative prognostic value of high BUN levels, our data seemto indicate that PTBD should not be performed when severe renal insufficiency is present. Other parameters correlated with a short survival after PTBD were the histotype of metastasis (in comparison with the other ones) and in large neoplastic volume (in comparison with a small and medium ones). Through pre-PTBD radiological and laboratory data analysis, a group of patients can be selected in whom the procedure will increase neither well-being nor survival, as plotted against those patients who are likely to benefit from biliary drainage

  2. 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.

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

    Objective: To compare MR and CT cholangiography (MRC and CTC) in evaluating the anatomy of the extrahepatic biliary tract and the pathology related to the gallbladder. Material and Methods: Twenty-three patients underwent MRC and CTC with a biliary contrast medium for investigation of biliary disease. 3D displays of both were also obtained. Endoscopic retrograde cholangiography was performed in 17 patients, and the pathology of all 23 was evaluated. Results: Overall, the image quality was higher with CTC than with MRC (4.7 vs 3.9, p<0.05). The cystic duct was demonstrated better by CTC than MRC (p<0.05). Multiplanar reformation (MPR) and source images provided additional information to that obtained from 3D MRC and CTC images. Gallstones were revealed in 6 patients by CTC and in 5 of these 6 by MRC. In 2 patients with cholecystitis, CTC demonstrated gallbladder wall thickening but MRC did not. In 3 patients with adenomyomatosis, MRC demonstrated Rokitansky-Aschoff sinuses (RAS) while CTC demonstrated focal gallbladder wall thickening in all 3 and RAS in 1 of them. Conclusion: Both MRC and CTC provided anatomical and pathological information about the biliary system. With both techniques, however, either MPR or source images proved necessary in addition for evaluating the biliary system anatomy and pathology. The gallbladder wall was depicted clearly in source CTC, but MRC is recommended for the evaluation of adenomyomatosis because its depicts RAS clearly. (orig.)

  16. 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

    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)

    By means of 99mTc-Mebrofenin hepatobiliary scintigraphy to diagnose neonatal biliary atresia and differentiate it from neonatal hepatitis syndrome. 99mTc-Mebrofenin scintigraphy were performed in 24 infants (15 males, 9 females) with persistent jaundice after birth from 1996, 11 to 1998,5. The age was from 23 days to 210 days (average 68.3 days). 99mTc-Mebrofenin was given intravenously as a radiopharmaceutical, the dose was 37 to 74 MBq according to the body weight. The infants should be fast 4 hours before imaging. The biliary tract imaging was performed routinely at 10 min, 15 min, 30 min, I h, 2 h, 4 h, 6 h postinjection and 24 h when it was necessary. The instrument was dual-detector SPECT (Helix-6D, Elscint com). The plane imaging was performed with high sensitivity low energy collimator. 99mTc-Mebrofenin began to concentrate in the liver within the first few minutes after injection, and by 15 minutes most of the radiopharmaceutical were removed from the blood stream and were concentrated within the liver in all children, 16 of whom failed to show bile excretion into the gall bladder and gut tract, and amount of radioactivity in the liver could be visualized at 24 hr postinjection. The diagnosis of biliary atresia and narrowed common bile duct were conformed at laparotomy and on clinical grounds in 11 of 16 children. The diagnostic sensitivity of atreslia (include narrowed common bile duct) was 100%, specificity was 62%. Delayed gall bladder and gut tract scintigraphy were showed in 6 children, 4 of whom were neonatal hepatitis. The jaundice caused by mother's milk was diagnosed in 4 cases, 2 of whom showed normal hepatobiliary. scintigraphy. Neonatal hepatitis syndrome was diagnosed in 9 children on clinical ground. Among them, 5 cases had shown no radioactivity appeared in gut at 24 hr and another 4 cases showed delayed imaging of gall bladder and gut tract. Because the specificity of this examination was lower, the clinical history, biochemistry tests

    To compare the outcome of patients affected by biliary leak after major biliary surgery and treated with percutaneous transhepatic biliary drainage (PTBD) alone with that of similar patients treated with PTBD and concurrent positioning of an occlusion balloon (PTBD-OB). We retrospectively reviewed the results of the use of PTBD or PTBD-OB performed at our institution from 2004 to 2008 in patients with post-surgical biliary leak. Sixteen patients entered the evaluation. PTDB alone was performed in 9 men (age 59.7 ± 13.4 years [mean ± standard deviation]; median 60 years), while PTBD-OB was performed in 7 patients (5 men, 2 women, age 71.3 ± 9.3 years; median 68 years). No significant difference between groups was found regarding age (p = 0.064) and sex (p = 0.175) distribution, number of procedures (3.1 ± 1.62; 2 vs 1.7 ± 1.1; 1, p = 0.151), and days of disease before recovery, death or modification of treatment (51.6 ± 66.8; 23 vs 18.6 ± 15.1; 14, p = 0.266). The number of patients treated with PTBD-OB who fully recovered (7/7, 100%) was significantly higher than that of patients treated with PTBD alone (4/9, 44%, p = 0.034). This procedure appears to be clinically effective, being associated with a higher probability of recovery in patients treated for post-surgical biliary leak. Further studies are needed to confirm these preliminary results. (orig.)

    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.

    2014-01-01

    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.

  5. Diagnosing pulmonary embolism

    2006-01-01

    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.

  11. Mechanisms of Biliary Plastic Stent Occlusion and Efforts at Prevention.

    Kwon, Chang-Il; Lehman, Glen A

    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.

  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)

  18. EUS-Guided Transduodenal Biliary Drainage in Unresectable Pancreatic Cancer with Obstructive Jaundice

    Directory of Open Access Journals (Sweden)

    Tiing Leong Ang

    2007-07-01

    Full Text Available Context Endoscopic transpapillary biliary drainage is the procedure of choice for biliary decompression in patients with unresectable pancreatic cancer. When ERCP is unsuccessful, the usual alternative is percutaneous transhepatic biliary drainage. Recently, the use of EUS-guided biliary drainage has been reported, but it is not clear whether it is feasible for this technique to find more widespread use as an alternative to failed ERCP. We herein describe our experience with two cases of unresectable pancreatic cancer associated with obstructive jaundice treated by EUS-guided biliary drainage. Case report Two men presented with obstructive jaundice due to unresectable pancreatic cancer. ERCP was unsuccessful in both cases because of complete tumor obstruction at the distal common bile duct. Both patients rejected the standard option of percutaneous transhepatic biliary drainage and EUS-guided biliary drainage was performed. The obstructed biliary system was successfully decompressed by the creation of a choledochoduodenal fistula and the insertion of a transduodenal biliary stent. Conclusion EUS-guided biliary drainage has the potential of replacing percutaneous transhepatic biliary drainage in unresectable pancreatic cancer with obstructive jaundice when ERCP is unsuccessful

    Abstract Although radiofrequency (RF) ablation has been accepted as a curative treatment modality for solid organ tumors, intraductal RF ablation for malignant biliary obstruction has not been widely described. The aim of this study was to evaluate the feasibility, safety, and efficacy (in terms of stent patency and survival) of intraductal RF ablation combined with biliary stent placement for nonresectable malignant biliary obstruction. A search of the nonresectable malignant extrahepatic biliary obstruction database (179 patients) identified 18 consecutive patients who were treated with biliary intraluminal RF ablation during percutaneous transhepatic cholangiodrainage and inner stent placement (RF ablation group) and 18 patients who underwent inner stent placement without biliary intraluminal RF ablation (control group). The patients were matched for tumor type, location of obstruction, tumor stage, and Child–Pugh class status. Primary endpoints included safety, stent patency time, and survival rates. The secondary endpoint was effectiveness of the technique. The RF ablation and control groups were closely matched in terms of age, diagnosis, presence of metastases, presence of locally advanced tumor, American Society of Anesthesiologists (ASA) grade, and chemotherapy regimen (all P > 0.05). The technical success rate for both groups was 100%. The median time of stent patency in the RF ablation and control groups were 5.8 (2.8–11.5) months and 4.5 (2.4–8.0) months, respectively (Kaplan–Meier analysis: P = 0.03). The median survival times in the RF ablation and control groups were 6.1 (4.8–15.2) months and 5.8 (4.2–16.5) months, with no significant difference according to Kaplan–Meier analysis (P = 0.45). In univariate and multivariate analyses, poorer overall survival was associated with advanced age and presence of metastases (P < 0.05). Intraductal RF ablation combined with biliary stent placement for nonresectable malignant

  20. 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.

  3. Renal cell carcinoma as an incident finding on hepato-biliary US

    International Nuclear Information System (INIS)

    Renal cell carcinomas are often diagnosed as incidental findings during abdominal US or CT carried out for extraurological reasons. In order to ascertain the incidence of renal carcinoma two groups of patients were considered: a) 2400 outpatients who had undergone hepato-biliary US for routine screening; b) 1330 in patients who had undergone US, for non-urological purposes, which had been systematically extended to the kidneys. Two cases of renal cell carcinoma (PT1) were found in group A. Four cases were found in group B - 2 of them were stage PT1, and 2 were PT3. These results show how a certain number of unsuspected and early-stage renal cell carcinomas can be diagnosed by US, even when the examination is not intended as a renal study. On the basis of the above observations, it is suggested that US be performed in all upper abdomen examinations. At any rate, right kidney US seems to us mandatory when hepatobiliary US is performed

    2014-05-01

    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. PMID:25298762

  6. Analysis of cases mis-diagnosed as hepatocellular carcinoma (with report of 5 cases)

    International Nuclear Information System (INIS)

    To improve the diagnostic accuracy of the hepatocellular carcinoma (HCC), the clinic, diagnostic imaging and laboratory data as well as the definite diagnosis, treatment and the follow-up of five cases mis-diagnosed as HCC before surgical therapy, were reviewed and analysed retrospectively. Five cases mis-diagnosed as HCC were confirmed pathologically as hepatic adenoma, biliary cystadenoma with malignant degeneration, isolated metastatic adenocarcinoma, malignant fibrous histocytoma of retroperitoneum and exogastric neurilemoma respectively. Of the 5 cases with surgical therapy, in 3 cases the mass could not be resected because of the huge tumor with abundant blood supply, interventional therapy or/and chemotherapy were used post surgically in 4 cases. 3 of the 5 cases with benign tumor survived on 3-year follow-up. Hepatic adenoma and biliary cystadenoma may be differentiated from HCC presurgically, if its characteristic features present on CT and angiography were recognized. Isolated metastasis of the liver with unknown site of primary tumor is difficult of differentiate from HCC, however, the ring-like enhancement of the tumor in CT and the doughnut and target signs present on MRI may be helpful to diagnose. In the most of retroperitoneal or abdominal neoplasms nearby the liver, the locative diagnosis can be definite presurgically if angiography was undertaken. Finally, confirmation of these neoplasms described as above must be depend upon the pathological examination yet

    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.

    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

    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.

  12. Biliary cholesterol secretion: More than a simple ABC

    Directory of Open Access Journals (Sweden)

    Arne Dikkers, Uwe JF Tietge

    2010-12-01

    Full Text Available Biliary cholesterol secretion is a process important for 2 major disease complexes, atherosclerotic cardiovascular disease and cholesterol gallstone disease. With respect to cardiovascular disease, biliary cholesterol secretion is regarded as the final step for the elimination of cholesterol originating from cholesterol-laden macrophage foam cells in the vessel wall in a pathway named reverse cholesterol transport. On the other hand, cholesterol hypersecretion into the bile is considered the main pathophysiological determinant of cholesterol gallstone formation. This review summarizes current knowledge on the origins of cholesterol secreted into the bile as well as the relevant processes and transporters involved. Next to the established ATP-binding cassette (ABC transporters mediating the biliary secretion of bile acids (ABCB11, phospholipids (ABCB4 and cholesterol (ABCG5/G8, special attention is given to emerging proteins that modulate or mediate biliary cholesterol secretion. In this regard, the potential impact of the phosphatidylserine flippase ATPase class I type 8B member 1, the Niemann Pick C1-like protein 1 that mediates cholesterol absorption and the high density lipoprotein cholesterol uptake receptor, scavenger receptor class B type I, is discussed.

  14. Absorption of biliary cobalamin in baboons following total gastrectomy

    International Nuclear Information System (INIS)

    Absorption of radiolabeled cobalamin in baboons was assessed by whole body counting. Retention of biliary cobalamin and an aqueous solution of cyanocobalamin was measured in normal baboons and in baboons after total gastrectomy by using 57Co-labeled biliary cobalamin and 58C0-cyanocobalamin, with and without baboon gastric juice containing intrinsic factor. Radiolabeled biliary cobalamin was obtained by intravenous injection of 57Co-cyanocobalamin in baboons and collection of bile through a cannula placed in the common bile duct. Cobalamin absorption was not completely abolished by gastrectomy and biliary cobalamin was better retained than cyanocobalamin; intrinsic factor enhanced absorption of both forms. After gastrectomy there was steady depletion of liver and serum cobalamin levels, which ceased after a new equilibrium was reached between a progressively diminishing cobalamin loss and the impaired but significant residual level of absorption. These studies in the nonhuman primate provide further information concerning the enterohepatic circulation of cobalamin and suggest that the form of cobalamin in bile may be more readily absorbed than is cyanocobalamin or that bile itself may have an enhancing effect on cobalamin absorption. The data also suggest that physiologically significant amounts of cobalamin may be absorbed in the absence of a gastric source of intrinsic factor

  16. 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

    Three types of preoperative biliary drainage (BD): percutaneous transhepatic (PTBD), endoscopic (EBD), and endoscopic nasobiliary (ENBD) can be indicated before resection of cholangiocarcinoma. However, three randomized controlled trials (RCTs) have revealed that preoperative PTBD does not improve perioperative results. Other RCTs have revealed that preoperative EBD for malignant obstructive jaundice has no demonstrable benefit and after EBD for hilar cholangiocarcinoma there are highly devel...

    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.

    bile duct, GB and duodenum was closely paralleled to the level of serum bilirubin when it is less than 10.5 mg/dl as shown in figure 1. 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.

  2. 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)

  4. 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.

    AIM:To determine the utility of endoscopic ultrasoundguided biliary drainage (EUS-BD) with a fully covered self-expandable metal stent for managing malignant biliary stricture.METHODS:We collected data from 13 patients who presented with malignant biliary obstruction and underwent EUS-BD with a nitinol fully covered selfexpandable metal stent when endoscopic retrograde cholangiopancreatography (ERCP) fails.EUS-guided choledochoduodenostomy (EUS-CD) and EUS-guided hepaticogastrostomy (EUS-HG) was performed in 9 patients and 4 patients,respectively.RESULTS:The technical and functional success rate was 92.3% (12/13) and 91.7% (11/12),respectively.Using an intrahepatic approach (EUS-HG,n =4),there was mild peritonitis (n =1) and migration of the metal stent to the stomach (n =1).With an extrahepatic approach (EUS-CD,n =10),there was pneumoperitoneum (n =2),migration (n =2),and mild peritonitis (n =1).All patients were managed conservatively with antibiotics.During follow-up (range,1-12 mo),there was re-intervention (4/13 cases,30.7%) necessitated by stent migration (n =2) and stent occlusion (n =2).CONCLUSION:EUS-BD with a nitinol fully covered self-expandable metal stent may be a feasible and effective treatment option in patients with malignant biliary obstruction when ERCP fails.

    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.

  7. Percutaneous Embolization of Transhepatic Tracks for Biliary Intervention

    International Nuclear Information System (INIS)

    Significant pain can occur after removing transhepatic catheters from biliary access tracks, after percutaneous biliary drainage (PBD) or stenting. We undertook a randomized prospective study to ascertain whether track embolization decreases the amount of pain or analgesic requirement after PBD. Fifty consecutive patients (M:F, 22:28; age range:29-85 years; mean age: 66.3 years) undergoing PBD were randomized to receive track embolization or no track embolization after removal of biliary drainage catheters. A combination of Lipoidol and n-butyl cyanoacrylate were used to embolize transhepatic tracks using an 8F dilator. The patients who did not have track embolization performed had biliary drainage catheters removed over a guide wire. A visual analog scoring (VAS) system was used to grade pain associated with catheter removal, 24 h afterward. A required analgesic score (RAS) was devised to tabulate the analgesia required. No analgesia had a score of 0, oral or rectal nonopiate analgesics had a score of 1, oral opiates had a score of 2, and parenteral opiates had a score of 3. The average VAS and RAS for both groups were calculated and compared.Seven patients were excluded for various reasons, leaving 43 patients in the study group. Twenty-one patients comprised the embolization group and 22 patients comprised the nonembolization group. The mean biliary catheter dwell time was not significantly different (p > 0.05) between the embolization group and nonembolization (mean: 5.4 days vs 6.9 days, respectively). In the nonembolization group, the mean VAS was 3.4. Eight patients required parenteral opiates, three patients required oral opiates, and five patients required oral or rectal analgesics, yielding a mean RAS of 1.6. In the embolization group, the mean VAS was 0.9. No patient required parenteral opiates, six patients required oral opiates, and two patients had oral analgesia. The average RAS was 0.6. Both the VAS and the RAS were significantly lower in the

    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.

    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. PMID:26438008

    2013-03-15

    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.

    2008-09-01

    Previous reports have indicated that in vitro biliary clearance (Cl(biliary)) determined in sandwich-cultured hepatocytes correlates well with in vivo Cl(biliary) for limited sets of compounds. This study was designed to estimate the in vitro Cl(biliary) in sandwich-cultured rat hepatocytes (SCRHs) of angiotensin II receptor blockers and HMG-CoA reductase inhibitors that undergo limited metabolism, to compare the estimated Cl(biliary) values with published in vivo Cl(biliary) data in rats, and to characterize the mechanism(s) of basolateral uptake and canalicular excretion of these drugs in rats. The average biliary excretion index (BEI) and in vitro Cl(biliary) values of olmesartan, valsartan, pravastatin, rosuvastatin, and pitavastatin were 15, 19, 43, 45, and 20%, respectively, and 1.7, 3.2, 4.4, 46.1, and 34.6 ml/min/kg, respectively. Cl(biliary) predicted from SCRHs, accounting for plasma unbound fraction, correlated with reported in vivo Cl(biliary) for these drugs. The rank order of Cl(biliary) values predicted from SCRHs was consistent with in vivo Cl(biliary) values. Bromosulfophthalein inhibited the uptake of all drugs. BEI and Cl(biliary) values of olmesartan, valsartan, pravastatin, and rosuvastatin, known multidrug resistance-associated protein (Mrp) 2 substrates, were reduced in SCRHs from Mrp2-deficient (TR(-)) compared with wild-type (WT) rats. Although Mrp2 plays a minor role in pitavastatin biliary excretion, pitavastatin BEI and Cl(biliary) were reduced in TR(-) compared with WT SCRHs; Bcrp expression in SCRHs from TR(-) rats was decreased. In conclusion, in vitro Cl(biliary) determined in SCRHs can be used to estimate and compare in vivo Cl(biliary) of compounds in rats and to characterize transport proteins responsible for their hepatic uptake and excretion.

    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.

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. PMID:3888131

    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.

  7. Primary Biliary Cirrhosis Is a Generalized Autoimmune Epithelitis

    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.

    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.

  10. 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)

    To evaluate the usefulness of percutaneous transhepatic biliary drainage (PTBD) tract dilatation using a Nipro set. We dilated 28 percutaneous biliary drainage tracts up to 18F; 26 procedures involved PTBD, and two, cholecystostomy. A Nipro set was used for dilatation, the purposes of which were stone removal (n=18) and choledochoscopic biopsy (n=10). For dilatation, local anesthesia was used in all cases. In all patients, tract dilatation was successful. In 21 of 28 cases, dilatation of the right PTBD tract was involved, and in five of 28, dilatation of the left tract. In two cases, tract dilatation was done in cholecystostomy tracts. Complications encountered were pain (n=17), bradycardia (n=2), hemobilia (n=2), bleeding (n=1), and fever (n=1). In choledocoscopy, tract dilatation using a Nipro set is safe and simple.

    Full Text Available Background Up to now, few data are available regarding the clinical characteristics of autoimmune hepatitis and primary biliary cirrhosis overlap syndrome. The study was to investigate and analyze the prevalent and clinical features of Chinese patients with this disease. Methods Clinical data on patients diagnosed as autoimmune hepatitis and primary biliary cirrhosis overlap syndrome in our hospital from January 2001 to December 2006 were collected and analyzed. Results Overlap syndrome of autoimmune hepatitis and primary biliary cirrhosis accounted for 10.33% of patients with autoimmune liver diseases during the past six years. For these patients with overlap syndrome, xanthochromia, lethargy and anorexia were the predominant complaints; a low incidence (14/146 of smooth muscle antibody positivity and a high incidence (37/89 of isolated IgM elevation were the main serological characteristics. Conclusions Overlap syndrome of autoimmune hepatitis and primary biliary cirrhosis was not rare in Chinese patients with clinical manifests of autoimmune liver diseases. Overlap of the diseases should not be disregarded when isolated IgM elevation was exhibited, and smooth muscle antibody might have little diagnostic significance in the overlap syndrome. If it was difficult to make a definite diagnosis, liver biopsy was necessary.

    The authors describe the case of a hemorrhagic pancreatitis with non-perforating biliary peritonitis. The abdomen symptomatology was hidden by the beginning contractions and due to the dystocia the delivery was finished by caesarean section. The presence of choleperitoneum required a surgical revision of the abdominal cavity which enabled to make the right diagnosis. This thesis deals with aetiology and mechanism of choleperitoneum inception during hemorrhagic pancreatitis. PMID:3788337

  19. Thick slice MR cholangiography of the intrahepatic biliary tree

    International Nuclear Information System (INIS)

    Purpose. To assess the value of single shot fast spin echo MR sequence (SS-FSE) in the evaluation of the normal and pathologic intrahepatic biliary tree. Material and Methods. 418 consecutive patients (457 examinations) referred for clinical and/or biological suspicion of biliary obstruction underwent MR cholangio-pancreatography (MRCP). All patients were imaged with a Signa 1.5 T GE MR unit, with High Gradient Field Strength and Torso Phased Array Coil. Biliary ducts were imaged with SS-FSE sequence, coronal and oblique coronal 20 mm thick slices on a 256 x 256 matrix. Total acquisition time was 1 second. Source images were reviewed by two radiologists blinded to clinical information. In case of disagreement, a third radiologist's opinion was requested. In all cases, MRCP results were compared with direct biliary tract evaluation, other imaging studies and clinical and biological follow-up. Results. In all cases, MRCP produced high quality images. Numerous branch of division were observed although the peripheral intrahepatic ducts were well seen in more than 90% in an area 2 cm below the capsule. The number of division was statistically higher when mechanical obstruction was present. Intrahepatic calculi or peripheral cholangio-carcinoma were well detect by MRCP. For the detection of cholangitis, MRCP sensitivity was 87.5% but the positive predictive value was only 57.7% because of a high number of false positive. The diagnosis of primary sclerosing cholangitis must be made only on strict criteria and slightly dilated peripheral bile ducts unconnected to the central ducts in several hepatic segments were a characteristic MR sign of primary sclerosing cholangitis. Conclusion. MRCP can be proposed as a first intention imaging technique for the evaluation of intrahepatic ducts. (authors)
