Sample records for biliary gallbladder emptying

  1. Evaluation of the biliary gallbladder emptying in patients with calcificant chronic pancreatitis through a scintilographic study with DISIDA Tc-99m

    International Nuclear Information System (INIS)

    The eventual relation between biliary lithiasis and chronic pancreatitis (CP) has been studied before but the research on the gallbladder involvement in chronic pancreatitis patients are rare, specially from a functional point of view. In order to study that, gallbladder emptying was evaluated in 11 patients with CP and the results were compared and analyzed statistically with the ones observed in 10 controls. This series exclude patients and controls who presented any kind of prior or current affection, or condition, that could interfere with the gastric or gallbladder emptying and the release of the entero pancreatic hormones. Gallbladder emptying was studied through the scintillographic method, using Tc-99m DISIDA, through the calculation of the ejection (EF) of the gallbladder (GB), at 30, 45 and 60 minutes. In the patients this evaluation was studied in two different periods of time with an interval of two to four weeks between them, without (CPWOP) and with (CPWP) the addition of pancreatic extract. The analyses of the results disclosed that the EF of GB at 60 minutes was significantly higher in the controls when compared tro chronic pancreatopaths. On the other hand, the EF of GB in these patients did not show any statistically significant differences after the administration of pancreatic extract. The results suggest that the delay in the gallbladder emptying does not depend exclusively on the eventual alteration in the intestinal phase of the gallbladder stimulation, but it probably also results from the association with other factors involved, as a mechanic factor, which depends on the compression of the main biliary tract through the chronic pathological process located in the cephalic portion of the pancreas.

    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.

  3. Gallbladder emptying with ceruletide in oral cholecystography

    International Nuclear Information System (INIS)

    In a consecutive series of 148 patients the gallbladder emptying in oral cholecystography was investigated after administration of ceruletide given in doses of 0.3 μg/kg body weight intramuscularly and 0.03 and 0.05 μg/kg intravenously. No essential side effects occurred. The effect of ceruletide seems to be on a par with that of cholecystokinin. A dose of 0.3 μg/kg was found to be sufficient to assess the gallbladder emptying, but then in a few instances the emptying is delayed - up to one hour. The bile ducts are best demonstrated after intravenous administration of 0.05 μg/kg. (Auth.)

    , gallbladder emptying and gastric emptying were examined. RESULTS: Gallbladder emptying increased with increasing meal fat content, but no intergroup differences were demonstrated. GIP and GLP1 responses were comparable among the groups with GIP levels being higher following high-fat meals, whereas GLP1......-induced GLP1 secretion combined with the findings of reduced postprandial gallbladder emptying in patients with type 2 diabetes (T2DM) led us to speculate whether reduced postprandial GLP1 responses in some patients with T2DM arise as a consequence of diabetic gallbladder dysmotility. DESIGN AND METHODS...... secretion was similar after both OGTT and meals. CONCLUSIONS: In conclusion, patients with T2DM exhibited normal gallbladder emptying to meals with a wide range of fat content. Incretin responses were similar to that in controls, and an association with postprandial gallbladder contraction could...

    AIM: To assess gallbladder emptying and its association with cholecystitis and abdominal pain in patients with primary sclerosing cholangitis (PSC). METHODS: Twenty patients with PSC and ten healthy subjects were investigated. Gallbladder fasting volume, ejection fraction and residual volume after ingestion of a test meal were compared in patients with PSC and healthy controls using magnetic resonance imaging. Symptoms, thickness and contrast enhancement of the gallbladder wall and the presence of cystic duct strictures were also assessed. RESULTS: Median fasting gallbladder volume in patients with PSC [67 (19-348) mL] was twice that in healthy controls [32 (16-55) mL] ( P < 0.05). The median postprandial gallbladder volume in patients with PSC was significantly larger than that in healthy controls ( P < 0.05). There was no difference in ejection fraction, gallbladder emptying volume or mean thickness of the gallbladder wall between PSC patients and controls. Contrast enhancement of the gallbladder wall in PSC patients was higher than that in controls; (69% ± 32%) and (42% ± 21%) ( P < 0.05). No significant association was found between the gallbladder volumes and occurrence of abdominal pain in patients and controls. CONCLUSION: Patients with PSC have increased fasting gallbladder volume. Gallbladder Mucosal dysfunction secondary to chronic cholecystitis, may be a possible mechanism for increased gallbladder.

    Gall-bladder emptying in response to a standard meal was assessed in 34 patients with radiolucent gall stones and 34 matched controls. Percentage gall-bladder emptying, derived from volume measurements made on standardised oral cholecystography, was significantly higher at 15 minutes in the patients than the controls (mean +/- SE of mean 38.0 +/- 3.7% v 28.0 +/- 3.8%). This difference was maintained at 30 and 60 minutes. It is concluded that postprandial gall-bladder emptying is increased in ...

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

  9. Gallbladder filling and post-ceruletide emptying in prairie dogs and rabbits.

    1988-05-01

    The filling and emptying characteristics of the gallbladder in prairie dogs and rabbits were studied to assess the importance of the residual bile in the pathogenesis of gallstones. In prairie dogs under ketamine/xylazine anesthesia, a significantly larger fraction (p = 0.001) of hepatic bile entered the gallbladder (87 +/- 8%) than the intestine during fasting and very little bile emptied (0-3% ejection fraction) following ceruletide infusion. In rabbits under similar anesthesia, only a small fraction of hepatic bile entered the gallbladder (4 +/- 2%) during fasting, and the gallbladder emptied almost completely (85% ejection fraction) following ceruletide infusion. The resultant higher residual bile in the prairie dog gallbladder and lower residual bile in the rabbit gallbladder may explain why gallstones form so readily in prairie dogs but not in rabbits when fed a lithogenic diet. These similarities and differences in gallbladder function must be taken into account when considering any animal as a model for gallstone formation. PMID:3412728

    We investigated fasting gallbladder volume and gallbladder emptying in response to a fatty meal in 20 patients with asymptomatic gallstones and compared the results with findings from healthy controls. Compared with control subjects without gallstones, the majority of patients with gallstones exhibited a higher resting gallbladder volume, less fractional emptying after a fatty meal, and a higher postmeal residual volume. These abnormalities all appeared to stem from an abnormally high resting gallbladder volume. Whether the increased gallbladder volume and decreased postprandial fractional emptying in the gallstone patients represents a primary or secondary abnormality remains to be determined. The results suggest that in some patients decreased gallbladder contractility may contribute to gallstone development or proliferation. PMID:3554918

    50 cases, aged between 14-60 years, clinically suspected of gall-bladder and biliary tract diseases were evaluated by ultrasonography and oral cholecystography. Ultrasound with a preliminary radiograph of gallbladder region, proved to be more sensitive and reliable procedure than oral cholecystography. Besides providing ancillary information regarding adjacent anatomic structures, it also guided the surgeon to decide preoperatively about the mode of surgery to be employed. Further, from the present study it can be fairly concluded that ultrasound should be used as the primary screening technique for evaluating gallbladder and biliary tract diseases, after plain skiagram of the gallbladder region, since it is non-invasive, more sensitive than OCG and is devoid of use of contrast media and its toxicity.

    Assessment of gallbladder function is required prior to nonsurgical treatment of gallstones. In order to develop a practical and reproducible method of evaluation, gallbladder emptying was studied by ultrasound (US) in 55 gallstone patients after intramuscular administration of ceruletide (0.3 micrograms/kg). In 27 of these subjects, the US procedure was compared to oral cholecystography (OCG) with fatty meal. Maximal percent gallbladder contraction was reached 30 min after ceruletide in all patients. Maximal percent contractions were 47.5 +/- 27.7 during US with ceruletide and 33.9 +/- 16.3 during OCG with fatty meal (p = 0.03). A significant linear relationship was found between the results obtained with the two different procedures (r = 0.57; p = 0.002). Serial US determinations of gallbladder emptying were performed in 16 patients. Individual variation was below 20% in 11 subjects, and in five subjects it ranged between 20 and 40%. Minor, self-limiting side effects were observed in 13 patients. US determination of gallbladder emptying after ceruletide appears to be a practical and reliable method to assess gallbladder function.

  13. Percutaneous Transcholecystic Biliary Interventions Using Gallbladder Anchors: Feasibility Study in the Swine

    International Nuclear Information System (INIS)

    The purpose of this study was to report our initial experience with a swine model for biliary interventions by using a percutaneous transcholecystic access after suture anchor of the gallbladder. Telepaque tablets were given to five pigs to opacify the gallbladder. Under fluoroscopy, the opacified gallbladder was punctured percutaneously and three suture anchors were used to fix the anterior wall of the gallbladder to the abdominal wall. Two weeks later, the gallbladder was punctured and access into the distal common bile was obtained through the cystic duct. Balloon expandable stents were deployed into the distal common bile duct. Follow-up cholangiograms were obtained at 1 and 2 weeks. Necropsy was performed after 2 weeks to evaluate the relationship between the gallbladder and abdominal wall. Suture anchor placement was successful in all five pigs. One pig with a deep and highly positioned gallbladder developed fever, anorexia, and vomiting secondary to excessive stretch of the gallbladder. Placement of the guidewire through the extremely tortuous and small cystic ducts proved to be the most challenging step of the procedure. Metallic stents were successfully deployed in all four pigs in which it was attempted. Four animals tolerated the procedures without changes in their clinical conditions and no symptoms. Successful follow-up cholangiograms were performed at 1 and 2 weeks post-stent deployment without complications. All stents remained patent during the follow-up period. Necropsy demonstrated close attachment and adherence of the gallbladders to the antero-lateral abdominal wall in all four animals. Suture anchoring of the gallbladder is feasible in most pigs with superficially located gallbladders. This technique allows a safe and repeat access into the biliary system using a transcholecystic approach

  14. Gallbladder emptying evaluation in calcific chronic pancreatitis using Tc-99m DISIDA scintigraphy

    International Nuclear Information System (INIS)

    The aim of this study was to analyze the gallbladder motor function in chronic pancreatitis (C) patients. Gallbladder emptying was evaluated in 11 patients, without and with addition of pancreatic extract and in ten controls. The results were compared and analyzed statistically. The ejection fraction (E F) of the gallbladder (GB) at 30, 45 and 60 minutes were calculated by using Tc-9 9 m DISIDA scintigraphy. The E F of GB at 60 minutes was significantly higher in the controls when compared to patients, although the results between patients were similar without and with addition of pancreatic extract. The results suggest that the delay in the GB emptying does not depend on the eventual alteration in the intestinal phase of the vesicular stimulation, but it probably results from a mechanic factor, which depends on the chronic pathological process located in the head of the pancreas.

    The characteristics of meal-induced gallbladder emptying in healthy individuals are subject to wide variation. We hypothesized that some of the observed variation might relate to ingestion of the meal during different phases of the migrating motor complex (MMC). Recording of gastrointestinal...... pressure was combined with scintigraphic recording of bile kinetics during infusion of 99mTc-HIDA. The material consisted of 12 healthy men. Group 1 (n = 6) had a fat-rich meal in phase I, and group 2 (n = 6) had the meal in a phase II. With the end of the meal ingestion as zero, the following results...... emerged. The subjects in group 1 had a median (range) lag period before beginning of gallbladder emptying of 13.5 (9.0-22.5) min. In group 2 gallbladder emptying began during the meal ingestion in four subjects, and the median lag period was 0 min (minimum, -9.0; maximum, 13.5 (p = 0.02)). The median...

    Percutaneous cholecystostomy is an established drainage procedure for the management of high-risk patients with acute cholecystitis. However, percutaneous image-guided access to the gallbladder may not be limited to the simple placement of a drain, but may also be used as an alternative approach to the biliary tree through the catheterization of the cystic duct, for a variety of other more complicated conditions. Percutaneous transcholecystic interventions may be performed in both malignant and benign disease. In the case of malignant jaundice, the transcholecystic route may be used when the liver parenchyma is occupied by metastatic lesions and transhepatic access is not possible. In benign conditions, access through the gallbladder may offer a solution if the biliary tree is not dilated. The transcholecystic access may then be route of insertion of large sheaths, internal drainage catheters, lithotripsy devices, stone retrieval baskets, and stents. The purpose of this review is to illustrate the techniques and to discuss the indications, complications, and technical difficulties of this alternative access to the biliary tree. PMID:25172204

    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.

    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.

  1. Scintigraphic study of gallbladder emptying and duodenogastric reflux during non-ulcerous dyspepsia

    International Nuclear Information System (INIS)

    Cholescintigraphy with 99mTc-labelled hydroxy imino diacetic acid (99mTc-HIDA) was used to study gallbladder emptying (GE) and duodenogastric reflux (DGR) simultaneously during the postprandial period in humans. Two groups of subjects were examined prospectively; one was a group of healthy volunteers (n=14) and the other a group of patients with non-ulcerous dyspepsia (NUD) (n=22). Symptoms were quantified using a clinical score (CS). GE kinetics was quantified according to two indices. DGR episodes were detected by an image-subtraction method and quantified. The group of patients with NUD showed significant early acceleration of GE (P1% in 3 of the 22 NUD patients. However, there was no correlation between the CS, GE kinetics and DGR episodes. The physiopathological mechanism and clinical significance of these digestive motility anomalies remain to be demonstrated. (orig.)

    Full Text Available Objective The present study explores the effects of +Gz exposure on the gallbladder emptying function,cholecystokinin(CCK,and somatostatin(SS in rabbits with high cholesterol diets and investigates its mechanism in the occurrence of cholecystolithiasis.Methods Twenty-four male New Zealand rabbits were randomly divided into the high cholesterol diet(control group,n=8 and high cholesterol diet plus +Gz exposure groups.The latter was divided into the four-and six-week +Gz exposure groups(n=8 based on the exposure time.Radioimmunoassay was used to determine the CCK and SS contents of the gallbladder at the end of the experiment in the fourth and sixth weeks and to calculate the gallbladder volume and maximum emptying ratio.A microcomputer biodynamic pressure monitor was used to record the hydrostatic pressure in the gallbladder to measure its capacity.Moreover,the bile properties and formation of concretion were observed with the naked eye,and polarized light microscopy was used to observe cholesterin crystallization on the gallbladder wall.Results The gallbladder capacity increased upon +Gz exposure for four and six weeks,indicating that the maximum emptying ratio(E% decreased,the empty and residual volumes improved,and the pressure increased(P < 0.05.After +Gz exposure for four and six weeks,the CCK contents in the experimental groups were evidently lower than that in the control group and gradually decreased(P < 0.05 as the +Gz exposure time increased.On the other hand,after +Gz exposure for four and six weeks,the SS contents in the experimental groups were higher than that in the control group and gradually improved(P < 0.05 as the +Gz exposure time increased.After +Gz exposure for four and six weeks,bile was turbid and sticky with cholesterol crystals and without visible concretion.Conclusions Therefore,+Gz exposure may cause abnormal gallbladder emptying functions,decrease CCK content,increase SS content,and thus cause bile stasis

    Conclusion: Duplication of the gallbladder is a rare congenital abnormality, which requires special attention to the biliary ductal and arterial anatomy. Laparoscopic cholecystectomy with intraoperative cholangiography is the appropriate treatment in a symptomatic gallbladder. The removal of an asymptomatic double gallbladder remains controversial.

  5. Gallbladder ejection fraction (GBEF) after cholecystokinin (CCK) infusion in patients with a low probability of biliary disease

    International Nuclear Information System (INIS)

    Full text: Compared with the rapid 3-minute injection of CCK, the twenty-minute infusion is claimed to give a higher and more reproducible GBEF. The purpose of this clinical study was to determine GBEF in patients considered not to have gallbladder disease. 112 consecutive patients with abdominal pain referred to Westmead Medical Imaging had DISIDA biliary scans with dynamic one minute images for 90 minutes. When the gallbladder was well filled (usually at 40-60 minutes) 0.01(g/kg of CCK was infused over 20 minutes. Quantitative assessment was performed by regions of interest over the liver, common bile duct and gallbladder and from the GB activity time curve, the GBEF was calculated. Nine patients were excluded because of previous cholecystectomy and six patients because of known gallbladder disease. Follow-up, a minimum of three months after their scan, was attempted in 97 patients, by contact with their referring doctors to ascertain whether the cause of the abdominal pain had been found. Information on 65 patients was obtained: three were lost to follow-up, 12 were considered to have gallbladder disease and 50 unlikely to have biliary disease on the basis of normal liver function tests and abdominal ultrasound. Only in a minority (6) was the cause of pain determined. The 50 patients (19 males and 31 females, mean age 48.5 yrs) had a mean GBEF of 56.8%±17.8%. Thus in a patient population with low probability of gallbladder disease there remains a wide range of GBEF despite the 20 minute CCK infusion.

  7. Targeting EGFR/HER2 pathways enhances the antiproliferative effect of gemcitabine in biliary tract and gallbladder carcinomas

    International Nuclear Information System (INIS)

    Advanced biliary tract carcinomas (BTCs) have poor prognosis and limited therapeutic options. Therefore, it is crucial to combine standard therapies with molecular targeting. In this study EGFR, HER2, and their molecular transducers were analysed in terms of mutations, amplifications and over-expression in a BTC case series. Furthermore, we tested the efficacy of drugs targeting these molecules, as single agents or in combination with gemcitabine, the standard therapeutic agent against BTC. Immunohistochemistry, FISH and mutational analysis were performed on 49 BTC samples of intrahepatic (ICCs), extrahepatic (ECCs), and gallbladder (GBCs) origin. The effect on cell proliferation of different EGFR/HER2 pathway inhibitors as single agents or in combination with gemcitabine was investigated on BTC cell lines. Western blot analyses were performed to investigate molecular mechanisms of targeted drugs. EGFR is expressed in 100% of ICCs, 52.6% of ECCs, and in 38.5% of GBCs. P-MAPK and p-Akt are highly expressed in ICCs (>58% of samples), and to a lower extent in ECCs and GBCs (<46%), indicating EGFR pathway activation. HER2 is overexpressed in 10% of GBCs (with genomic amplification), and 26.3% of ECCs (half of which has genomic amplification). EGFR or its signal transducers are mutated in 26.5% of cases: 4 samples bear mutations of PI3K (8.2%), 3 cases (6.1%) in K-RAS, 4 (8.2%) in B-RAF, and 2 cases (4.1%) in PTEN, but no loss of PTEN expression is detected. EGI-1 cell line is highly sensitive to gemcitabine, TFK1 and TGBC1-TKB cell lines are responsive and HuH28 cell line is resistant. In EGI-1 cells, combination with gefitinib further increases the antiproliferative effect of gemcitabine. In TFK1 and TGBC1-TKB cells, the efficacy of gemcitabine is increased with addiction of sorafenib and everolimus. In TGBC1-TKB cells, lapatinib also has a synergic effect with gemcitabine.

  10. Scintigraphic functional study of gallbladder dynamics in a developing country

    International Nuclear Information System (INIS)

    The frequency of cholelithiasis in Chile is high. The ethiopathogeny of this disease is multifactorial and the gallbladder physiology probably has a relevant role in it. The authors considered the characterization of gallbladder dynamics in a reference population in basal condition and after the physiological stimulus of a standard liquid food. 185 MBq of 99Tcm DISIDA was administered to 19 young adults following a biliary echographic study which produced normal results (11 males, 8 females with an average age of 21.7 years) and after 60 min of equilibration (when gallbladder activity was well delimited with almost nil hepatic activity) the area of interest was centred on the gallbladder area. The basal activity was evaluated over a period of 10 min; thereafter a liquid diet was ingested and activity in the area of interest was observed over 90 min. In all cases spontaneous passage of activity to the duodenal area in the fasting period was found. Two types of gallbladder emptying were characterized: Type I, fast emptying, (n=11) an ejection fraction at 30 min of 50%, and Type II, slow emptying (n=8) with a 30 min ejection fraction of only 17%. Both groups showed a biphasic component in the gallbladder kinetics; no significant differences between the sexes were detected. The consistency of the type of emptying in each individual was evaluated and found reproducible after 6 months. To characterize these findings further gallbladder kinetics were evaluated under a standard pharmacological stimulus of IV administration of octapeptide cholecystokinin (CCK-8) with a physiological dose of 14 pMol/kg per hour. Four individuals with secretory pattern type I and 6 individuals with excretory pattern type II were evaluated. Under CCK-8 stimulation the type I individuals did not change their basic pattern of excretion while type II individuals accelerated their excretion, with similar curves as described previously for type I. The authors conclude that hepatobiliary

  11. Gastric emptying and sieving of solid food and pancreatic and biliary secretions after solid meals in patients with nonresective ulcer surgery

    International Nuclear Information System (INIS)

    This study was undertaken to compare with previously published findings in normal subjects and subjects after truncal vagotomy and antrectomy the effects of nonresective ulcer surgery on (a) gastric emptying, grinding, and sieving of solid food and on (b) pancreatic and biliary secretions. Six subjects with proximal gastric vagotomy and 7 subjects with truncal vagotomy with pyloroplasty were studied using a previously validated indicator perfusion system with its aspiration port placed in the proximal jejunum. All subjects were given a meal of 30 g of /sup 99m/Tc-liver, 60 g of beefsteak, and 100 ml of H2O. In conjunction with a gamma-camera to measure total gastric emptying of /sup 99m/Tc-liver, this method allowed the estimation of the fraction of 99mTc-liver emptied from the stomach as particles of less than 1-mm diameter; in addition, it was possible to measure jejunal concentrations and outputs of bile salts and pancreatic enzymes. In subjects with proximal gastric vagotomy, all parameters studied were indistinguishable from normal. Subjects with truncal vagotomy and pyloroplasty behaved similarly to subjects with vagotomy and antrectomy, showing (a) early precipitous emptying of food, (b) heterogeneous distribution of half-emptying times, (c) near normal concentration of biliary and pancreatic secretions, (d) markedly reduced jejunal flow rates, and (e) a reduction in postcibal trypsin secretion. In contrast to subjects after truncal vagotomy and antrectomy, however, the majority of subjects with vagotomy and pyloroplasty did not show a persistent defect in grinding and sieving of solid food

    The gallbladder stores and concentrates bile between meals. Gallbladder motor function is regulated by bile acids via the membrane bile acid receptor, TGR5, and by neurohormonal signals linked to digestion, for example, cholecystokinin and FGF15/19 intestinal hormones, which trigger gallbladder emptying and refilling, respectively. The cycle of gallbladder filling and emptying controls the flow of bile into the intestine and thereby the enterohepatic circulation of bile acids. The gallbladder also largely contributes to the regulation of bile composition by unique absorptive and secretory capacities. The gallbladder epithelium secretes bicarbonate and mucins, which both provide cytoprotection against bile acids. The reversal of fluid transport from absorption to secretion occurs together with bicarbonate secretion after feeding, predominantly in response to an adenosine 3',5'-cyclic monophosphate (cAMP)-dependent pathway triggered by neurohormonal factors, such as vasoactive intestinal peptide. Mucin secretion in the gallbladder is stimulated predominantly by calcium-dependent pathways that are activated by ATP present in bile, and bile acids. The gallbladder epithelium has the capacity to absorb cholesterol and provides a cholecystohepatic shunt pathway for bile acids. Changes in gallbladder motor function not only can contribute to gallstone disease, but also subserve protective functions in multiple pathological settings through the sequestration of bile acids and changes in the bile acid composition. Cholecystectomy increases the enterohepatic recirculation rates of bile acids leading to metabolic effects and an increased risk of nonalcoholic fatty liver disease, cirrhosis, and small-intestine carcinoid, independently of cholelithiasis. Among subjects with gallstones, cholecystectomy remains a priority in those at risk of gallbladder cancer, while others could benefit from gallbladder-preserving strategies. © 2016 American Physiological Society.

  17. Gallbladder function in diabetic patients

    International Nuclear Information System (INIS)

    Gallbladder emptying and filling was studied in eight diabetic and six normal control patients. None of the patients had gallstones. Cholescintigraphy was performed using [/sup 99m/Tc]disofenin, and gallbladder emptying was studied using a 45-min i.v. infusion of the octapeptide of cholecystokinin (OP-CCK) 20 ng/kg X hr. The peak filling rate was greater in diabetic than in normal subjects; however, emptying of the gallbladder in response to OP-CCK was significantly less in the diabetic subjects (51.6 +/- 10.4% compared with 77.2 +/- 4.9%). When the diabetic group was subdivided into obese and nonobese diabetics, the obese diabetics had a much lower percentage of emptying than the nonobese diabetics (30.0 +/- 10.4% compared with 73.1 +/- 9.3%). These findings suggest that obese diabetics may have impaired emptying of the gallbladder even in the absence of gallstones. The more rapid rate of gallbladder filling in obesity may indicate hypotonicity of the gallbladder. The combination of these abnormalities may predispose the obese diabetic to the development of gallstones

    AIM: To investigate the clinical value of ultrasonographic diagnosis of biliary atresia (BA), a retrospective analysis of the sonogram of 20 children with BA was undertaken.METHODS: Ultrasonography (US) was performed in 20 neonates and infants with BA, which was confirmed with cholangiography by operation or abdominoscopy. The presence of triangular cord, the size and echo of liver, the changes in empty stomach gallbladder and postprandial gallbladder were observed and recorded.RESULTS: The triangular cord could be observed at the porta hepatis (thickness: 0.3-0.6cm) in 10 cases. Smaller triangular cord (0.2-0.26cm) can be observed in 3 cases. The gallbladder was not observed in 2 cases, and 1 case showed a streak gallbladder without capsular space. The gallbladders of 15 cases were flat and small. The gallbladders of 2 cases were of normal size and appearance, however, there was no postprandial contraction. The livers of all cases showed hepatomegaly and hetreogeneous echogenicity. Statistical analysis was performed to compare the hepatomegaly and hetreogeneous echogenicity and the stage of hepatic fibrosis.CONCLUSION: The presence of the triangular cord at the porta hepatis is specific. However, it is not the only diagnostic criterion, since flat and small gallbladder and poor contraction are also of important diagnostic and differential diagnostic significance. The degree of hepatomegaly and hetreogeneous echogenicity is proportional with liver fibrosis, and able to indicate the duration of course and prognosis.

  1. Gallbladder ejection fraction (GBEF): after 0.02(G/KG cholecystokinin (CCK) infusion over 30 minutes in patients with a low probability of gallbladder disease

    International Nuclear Information System (INIS)

    Full text: Recent literature suggests that an infusion of 0.02 (g/Kg of CCK results in a narrower range of normal GBEF than an infusion 0.01(g/Kg of. Our aim was to investigate the effect of a 30-minutes infusion of 0.02 (g/Kg, in patients with a low probability of gallbladder disease. Sixty patients presenting with abdominal symptoms were referred to West mead Medical Imaging over a 9-month period for DISIDA biliary scans. 1-minute dynamic images were collected over 90 minutes. The CCK infusion was commenced when the gallbladder was well filled. GBEF was calculated from background corrected time activity curves over the gallbladder. Sixteen patients were excluded because of previous cholecystectomy or known gallbladder disease. Thirty-three patients were considered to have a low probability of gallbladder disease after final diagnoses were obtained from referring doctors. The mean GBEF for this group was 65.6%, SD 17.2 with a mean range 28-98% compared with mean 56.9%, SD 18.1 with a mean range 21-85% of our previous study using 0.01(gCCK. Females exhibited lower GBEFs than males while females under 50 gave the lowest mean. We concluded that the higher dose infusion causes more complete gallbladder emptying, and that there is a difference in GBEF between males and females of different ages. We question the validity of the same 'Normal' range being applied to both genders and all age groups. Copyright (2003) The Australian and New Zealand Society of Nuclear Medicine Inc

    2015-01-01

    Gallbladder mucocoele (GBM) is an abnormal, intraluminal accumulation of inspissated bile and/or mucous within the gallbladder. Older, small- to medium-breed dogs seem to be predisposed, but no sex predilection has been identified. Clinical signs are often non-specific and include vomiting, lethargy, anorexia, abdominal pain, icterus and polyuria-polydipsia. Results of a complete blood count may be unremarkable, but serum biochemistry usually reveals increased liver enzymes. The ultrasonographic appearance is diagnostic and well described in the literature. Surgical intervention for the treatment of GBM remains the therapeutic gold standard, with short- and long-term survival for biliary surgery being 66%. The worst outcome is seen in those dogs requiring cholecystoenterostomy. With GBM becoming an apparently increasingly common cause of extrahepatic biliary disease in canines, it is essential that clinicians become familiar with the current literature pertaining to this condition. Numerous predisposing factors are highlighted in this review article and the role of certain endocrinopathies (e.g. hyperadrenocorticism and hypothyroidism) in the development of GBM is touched upon. Furthermore, the aetiopathogenesis of this disease is discussed with reference to the latest literature. Cholecystectomy remains the treatment of choice, but other options are considered based on a current literature review. PMID:26824341

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

    Gallstone disease (GSD) is one of the most common biliary tract diseases worldwide in which both genetic and environmental factors have roles in its pathogenesis. Biliary cholesterol supersaturation from metabolic defects in the liver is traditionally seen as the main pathogenic factor. Recently, there have been renewed investigative interests in the downstream events that occur in gallbladder lithogenesis. This article focuses on the role of the gallbladder in the pathogenesis of cholesterol GSD (CGD). Various conditions affecting the crystallization process are discussed, such as gallbladder motility, concentrating function, lipid transport, and an imbalance between pro-nucleating and nucleation inhibiting proteins.

  5. Effects of peptide YY on gallbladder motility

    International Nuclear Information System (INIS)

    The effects of peptide YY (PYY) on cholecystokinin-stimulated gallbladder contraction were investigated in the prairie dog model. Twelve animals underwent laparotomy with catheter placement into the gallbladder and common bile duct (vent). The gallbladder was continuously perfused with [14C]polyethylene glycol-labeled lactated Ringer at 0.03 ml/min, and vent effluent was collected at 2.5-min intervals. All animals received 20 min of intravenous infusion of cholecystokinin octapeptide (CCK-OP), 2.5 ng x kg-1 x min-1, immediately followed by 60-min infusions of either lactated Ringer (LR) or synthetic PYY, 10 or 50 ng x kg-1 x min-1. When LR was infused after CCK-OP, gallbladder filling increased by 15.4 +/- 10.5% with minimal changes in gallbladder pressure. Infusion of PYY10 resulted in a significant increase in gallbladder volume and filling with a significant decrease in intragallbladder pressure. Similar findings were noted with PYY50. These data indicate that synthetic PYY significantly augments gallbladder filling after CCK-OP-stimulated gallbladder contraction. These finding, coupled with the observation that PYY inhibits pancreatic secretion, suggest that this peptide may be the anti-CCK hormone and may have an important role in regulating biliary activity postprandially

    Thirty consecutive patients with intact gallbladders and biliary pain were evaluated to determine whether gallbladder ejection fraction could identify sphincter of Oddi dysfunction. The mean gallbladder ejection fraction was 45% in patients with abdominal pain and 72% in normal controls. Gallbladder ejection fractions were then correlated with endoscopically measured sphincter of Oddi pressures in patients with abdominal pain. The mean gallbladder ejection fraction was 41% in 7 patients with elevated sphincter pressures and 46% in 23 patients with normal pressures (P = NS). Thirty-six percent of patients with elevated pressures and 33% of patients with normal pressures had abnormal gallbladder ejection fractions. Gallbladder ejection fraction had a sensitivity of 33%, a specificity of 63%, and a positive predictive value of 25% for detection of elevated pressures. Regression analysis revealed a poor correlation between sphincter pressure and gallbladder ejection fraction (r2 = 0.02). These findings suggest that gallbladder ejection fraction cannot be used to diagnose sphincter of Oddi dysfunction in patients before they undergo cholecystectomy. PMID:7955753

    2003-01-01

    Full Text Available INTRODUCTION Polypoid lesions of the gallbladder can be divided into benign and malignant categories. Malignant polypoid lesions include carcinomas of the gallbladder, which is the fifth most common malignancy of the gastrointestinal tract and the most common malignancy of the biliary tract. Benign polypoid lesions of the gallbladder are divided into true tumors and pseudotumors. Pseudotumors account for most of polypoid lesions of the gallbladder, and include polyps, hyperplasia, and other miscellaneous lesions. Adenomas are the most common benign neoplasms of the gallbladder. Cholesterol polyps are the most common pseudotumors of the gallbladder. The polyps can be single or multiple, usually less than 10 mm in size. They have no predilection for any particular gallbladder site, and usually are attached to the gallbladder wall by a delicate, narrow pedicle. No malignant potential has been identified for this type of pseudotumor. Adenomas are the most common benign neoplasms of the gallbladder. They have no predilection site in the gallbladder, and may also be associated with gallstones or cholecystitis. The premalignant nature of adenomas remains controversial. Ultrasonography (US has been demonstrated to be significantly better in detecting polypoid lesions of the gallbladder as compared with computed tomography and cholecystography. A mass fixed to the gallbladder wall of normal thickness, without shadowing, is seen in case of gallbladder polyp. Since gallbladder cancers usually present as polypoid lesions, differentiation between benign polypoid lesion and malignant lesion can be very difficult, even with high-resolution imaging techniques. PATIENTS AND METHODS Retrospectively we have analyzed 38 patients with ultrasonographicaly detected gallbladder polyps during the period from January 1995 to December 2000, who were treated at surgical department of Health Centre in Uzice and at Surgical clinic of Clinical Centre in Nis. We have analyzed

  8. Biliary scintigraphy in acute pancreatitis

    International Nuclear Information System (INIS)

    A prospective study was carried out in 60 patients to determine the efficacy of 99/sup m/Tc-PIPIDA scintigraphy in differentiating biliary pancreatitis from nonbiliary pancreatitis. 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

    Full Text Available Abstract Introduction Torsion of the gallbladder is a rare condition that most commonly affects the elderly. Pre-operative diagnosis is the exception rather than the rule. Any delay in treatment can be fatal as the gallbladder may rupture, leading to biliary peritonitis. Case presentation We present the case of an 80-year-old woman who was admitted with right upper quadrant pain initially thought to be secondary to acute cholecystitis. Subsequent ultrasound and computed tomography scans of the abdomen revealed signs suggestive of acute cholecystitis but neither modality detected any gallstones. As the patient's symptoms failed to resolve on conservative management, she was taken to theatre for an open cholecystectomy. Intra-operatively, the gallbladder had undergone complete torsion and appeared gangrenous. A routine cholecystectomy followed and she recovered from the operation without incident. Conclusion It is rare to diagnose torsion of the gallbladder pre-operatively despite advances in diagnostic imaging. However, this differential diagnosis should be borne in mind particularly in the elderly patient, without proven gallstones, who fails to improve on conservative management. An emergency cholecystectomy is indicated in the event of diagnosing torsion of the gallbladder to avert the potentially lethal sequelae of biliary peritonitis.

    AIM: To detect the patients with and without pancreaticobiliary maljunction who had pancreatobiliary reflux with extremely high biliary amylase levels.METHODS: Ninety-six patients, who had diffuse thickness (>3 mm) of the gallbladder wall and were suspected of having a pancreaticobiliary maljunction on ultrasonography, were prospectively subjected to endoscopic retrograde cholangiopancreatography, and bile in the common bile duct was sampled. Among them,patients, who had extremely high biliary amylase levels (>10000 IU/L), underwent cholecystectomy, and the clinicopathological findings of those patients with and without pancreaticobiliary maljunction were examined.RESULTS: Seventeen patients had biliary amylase levels in the common bile duct above 10000 IU/L, including 11 with pancreaticobiliary maljunction and 6 without pancreaticobiliary maljunction. The occurrence of gallbladder carcinoma was 45.5% (5/11) in patients with pancreaticobiliary maljunction, and 50% (3/6) in those without pancreaticobiliary maljunction.CONCLUSION: Pancreatobiliary reflux with extremely high biliary amylase levels and associated gallbladder carcinoma could be identified in patients with and without pancreaticobiliary maljunction, and those patients might be detected by ultrasonography and bile sampling.

    Abstract Previous studies have shown a positive association between chronic typhoid carriage and biliary cancers. 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) ...

  13. Gallbladder motility assessment in the patients after gastric surgery by infusion cholescintigraphy

    International Nuclear Information System (INIS)

    Background: The aim of the study is to evaluate gallbladder (GB) motor function, by infusion cholescintigraphy, in patients after total gastrectomy (Roux-en-Y) with expected disturbances in physiological regulation of biliary tract motility. Methods: The study was done in 10 controls, as well as in 12 patients early (less than 2 months) and in 14 patients late (6 months - 2 years) after the surgery. Anterior abdominal imaging by gamma camera and computer acquisition was performed during three-hours' infusion of 150 MBq, preceded by the loading dose of 50 MBq of 99mTc-EHIDA in bolus injection. The test meal stimulation was done at 120th minute of the study. GB TA curve was obtained and five parameters of GB motility were analyzed: durations of filling (ascending) and emptying (descending) phases, filling and emptying rate ratio, and ejection fraction and rate. Results: Our results have shown that, in the early period after the operation GB filling is prolonged and emptying impaired, while after several months GB motor function is normalized. Conclusions: It can be concluded that the infusion cholescintigraphy is potentially useful in patients after such surgery to decide on the specific treatment introduction in order to prevent GB calculosis and other complications

    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.

  19. Early Diagnosis of Gallbladder Carcinoma: An Algorithm Approach

    International Nuclear Information System (INIS)

    Gall bladder carcinoma is the most common biliary tract cancer. Delayed presentation and early spread of tumor make it one of the lethal tumors with poor prognosis. Considering that simple cholecystectomy for T1 disease could offer a potential cure, it is increasingly needed to identify it at early stages. Identification of high-risk cases and offering prophylactic cholecystectomy can decrease the incidence of gallbladder carcinoma. With advances in diagnostic tools like contrast-enhanced endoscopic ultrasound, elastography, multidetctor CT, MRI, and PET scan, we can potentially diagnose gallbladder carcinoma at early stages. This paper reviews the various diagnostic modalities available and an algorithmic approach to early diagnosis of gallbladder carcinoma

  20. Ultrasonographic diagnosis of gallbladder carcinoma: diagnostic difficulties and pitfalls

    International Nuclear Information System (INIS)

    Ultrasonographic findings of 60 patients with histologically verified primary gallbladder carcinoma were analyzed with special emphasis in diagnostic difficulties and pitfalls, sonographic diagnosis was correct in 40 patients, thus the sensitivity was 66.7%. Sonography of 20 incorrectly diagnosed cases were interpretated as benign biliary disease in 15(complicated cholecystitis in 9, gallbladder or bile duct stone in 6) and malignant disease in 5 with incorrect diagnosis of primary site. Thickened wall type was the most frequent type of false negative cases. The causes of sonographic diagnostic difficulty or pitfalls were 1) poor criteria of benign vs malignant wall thickening because of frequent association of complicated cholecystitis in gallbladder carcinoma,2) Overlook of small gallbladder lesions in cases with common bile duct disease including stone.3) inadequate study or technical problem especially in cases of localized carcinoma involving the fungus, neck or anterior wall. Knowledge of these diagnostic pitfalls may result in more accurate diagnosis of gallbladder carcinoma

    The authors viewed the present status of CT diagnosis in pancreatic and biliary diseases, referring to its future. CT imaged neither normal intrahepatic biliary ducts nor normal pancreatic ducts because of a relatively low resolution. The accuracy of CT in diagnosing obstructive jaundice has been 85 - 100%. CT showed a higher reproducibility than that of ultrasound in follow-up of intrahepatic gallstones. On the other hand, ultrasound was superior to CT in detecting gallstones. Diagnosis of cholecystitis by CT was usually impossible. Detecting early stage of gallbladder cancer by CT is very rare, but it was of value for investigating the extent of advanced cancers. This tendency was also observed in biliary duct carcinoma, acute and chronic pancreatitis, and carcinoma of the pancreas. Consequently, it was concluded that CT is not appropriate for the purpose of early detection of pancreatic and other cancers. The use of CT with NMR is expected in future.

  9. 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

    Full Text Available Context This is the first report associating heterotopic pancreas in the gallbladder and elevated pancreatic enzymes in bile. Case report A 60-year-old woman underwent abdominal ultrasonography at a medical check-up, revealing a nodular protrusion at the neck of the gallbladder. It seemed likely to be a lymph node, but we could not exclude the possibility of gallbladder cancer. In order to make a correct diagnosis, laparoscopic cholecystectomy was successfully performed. Pathological examination revealed heterotopic pancreatic tissue in the gallbladder wall. In addition, we detected elevated levels of amylase and lipase in gallbladder bile. Conclusions Preoperative diagnosis of heterotopic pancreas in the gallbladder is difficult. However, an increase of pancreatic enzymes in gallbladder bile may potentially play an important role in the occurrence of acalculous cholecystitis and biliary cancer. We need more accumulation of cases to know the true significance of this anomaly.

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

    International Nuclear Information System (INIS)

    Nonsurgical methods of methods of treating gallstones, contact dissolution and extracorporeal shock wave lithotripsy, increase the demand for gallbladder intervention. It is important to determine the safety of these procedures. Fifty-six procedures were performed in 46 patients. Diagnostic studies included needle aspiration of bile (n = 5) and transcholecystic cholangiography (TCC)(n = 31). Therapeutic procedures, percutaneous cholecystostomy (PC)(n = 20), were performed for biliary decompression or stone dissolution. Guidance was by US and fluoroscopy. All the TCC studies were diagnostic, 22 of 31 patients had normal ducts, one had common bile duct (CBD) stones without dilatation, one had dilated ducts without obstruction, and seven had CBD obstruction. PC was successful in all 20 patients. Ten were thought to have cholecystitis or biliary sepsis. Only four of ten showed significant improvement after PC. Local bile peritonitis occurred in two of 31 patients after TCC. Two of 20 undergoing PC had complications; one had 2-3 hours of abdominal pain, and one had peritonitis lasting for 4 days

    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.

    Full Text Available Context Long-standing diabetes mellitus results in autonomic nervous system dysfunction, leading to gastroparesis and cholecystoparesis. The latter can result in hydropic gallbladder, a condition that arises from the accumulation of mucinous secretions within the gallbladder, usually caused by obstruction of the cystic duct, but not in the case of the patients with diabetes that we have illustrated. Case report We describe three patients who presented with non-specific abdominal discomfort at the time of admission for complications of poorly controlled diabetes and were subsequently found to have hydropic gallbladder. We theorize that hydropic gallbladder may be a result of a natural progression of gallbladder dysfunction in poorly controlled diabetics with autonomic neuropathy. In our cases the risk of perioperative mortality was high at the time of presentation. No surgical intervention was performed except in one case with the most significant sized gallbladder, and underwent a temporizing cholescystostomy. Conclusions The development of hydropic gallbladder in patients with non-obstructed cystic ducts highlights the complexities of management of patients with functional biliary pain. The rome committee on functional biliary and pancreatic disorders has defined the characteristics of this pain. There is a need for guidelines to direct appropriate assessment of hydropic gallbladder in diabetics and also to determine the indications for cholecystectomy.

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

    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.)

    Impaired gallbladder motility may contribute to gallstone pathogenesis by providing time for nucleation and aggregation of cholesterol crystals. Simultaneous scintigraphic-ultrasonographic techniques have been proposed to assess alternating phases of gallbladder emptying and filling. To evaluate patterns of gallbladder motility and of postprandial bile flow by means of a single ultrasonographic technique, 12 healthy volunteers and 20 gallstone patients underwent minute-by-minute gallbladder ultrasonography for 3 h postprandially. Mathematical analysis of volume measurements was used to estimate hepatic and cholecystic bile flux through the gallbladder.

    Full Text Available Abstract Background Biliary tract cancers have limitations in information about different location-related pathogenesis and clinico-pathological characteristics. The goal of this study was to investigate anatomical site-related similarities and differences in biliary tract cancers and to assess the expression and clinical significance of functional proteins such as p53, cyclin D1, survivin, thymidine phosphorylase, and ERCC1. Methods One hundred and sixty-one patients with biliary tract adenocarcinomas, who underwent curative or palliative surgery in a single institution between October 1994 and December 2003 were evaluated, retrospectively. The level of protein expression of p53, cyclin D1, survivin, thymidine phosphorylase, and ERCC1 was assessed by immunohistochemistry. Results With respect to clinico-pathological characteristics, gallbladder cancer was more frequent in women, and bile duct cancer was more common in men. Perineural invasion was more common in bile duct cancer. Recurrence as a distant metastasis was more common in gallbladder cancer. Immunohistochemical analysis revealed that thymidine phosphorylase expression was significantly higher in gallbladder cancer than in bile duct cancer. Positive thymidine phosphorylase and p53 staining were associated with an advanced stage. Differentiation, vascular invasion, perineural invasion, lymphatic invasion, lymph node metastasis, and TNM stage independently predicted poor prognosis in biliary tract cancer. These correlations were seen more clearly in gallbladder cancer. The immunohistochemical staining patterns of p53, cyclin D1, survivin, thymidine phosphorylase, and ERCC1 showed no prognostic significance in biliary tract cancers. Conclusions We concluded that gallbladder and bile duct cancers are considered to be separate diseases with different clinico-pathological characteristics and prognostic factors. In addition, we hypothesize that high expression of thymidine phosphorylase by

  4. 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

    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.)

There are no pathognomonic signs, the diagnosis depends on suspicion of tuberculosis, peroperative findings and histological examination.

  8. 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

    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

    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.

    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

    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.

    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.

  3. Influence of sex and age on fasting and post-prandial gallbladder volumes

    International Nuclear Information System (INIS)

    Aging and female sex are major risk factors for cholesterol gallstones: in addition to hepatic secretion of lithogenic bile, decreased gallbladder contractility may play a role in such physiological conditions. This study was aimed at evaluating the effect of age and sex on gallbladder kinetics in healthy subjects. Gallbladder volume was measured on the US images of 157 fasting subjects using the sum-of-cylinders method. No significant difference was observed between males and females. On the contrary, age was shown to have a significant positive correlation with fasting gallbladder volume, particulary in males. In a second group of 63 healthy volunteers gallbladder volumes were evaluated both before and after a standard meal. The subjects were grouped according to age, and fasting gallbladder volume appeared to be significantly greater in the groups formed by older people. Gallbladder volumes were compared in younger groups (under 35), and gallbladder emptying resulted to be much more complete in males than in females. On the contrary, no significant differences was observed between males and famales over50 - which suggests a possible role of sex - and age-related hormonal factors. The above changes in gallbladder function may facilitate bile stasis which might in turn contribute to the increased risk for cholesterol gallstones notoriously associated with advanced age and female sex

    In this study, synchronous spontaneous, independent liver and gallbladder tumours were detected in a Bearded dragon (Pogona vitticeps). The multiple tumours consisted of intrahepatic cholangiocarcinoma as well as in situ adenocarcinoma and two adenomas of the gallbladder. The biliary epithelial cells and the cholangiocarcinoma showed membranous cross-immunoreactivity for claudin-7. The gallbladder epithelial cells, its adenoma and adenocarcinoma showed basolateral cross-reactivity for claudin-7. We think that the humanised anti-claudin-7 antibody is a good marker for the detection of different primary cholangiocellular and gallbladder tumours in Bearded dragons. The cholangiocytes, the cholangiocarcinoma, the endothelial cells of the liver and the epithelial cells and gallbladder tumours all showed claudin-5 cross-reactivity. The humanised anti-cytokeratin AE1-AE3 antibody showed cross-reactivity in the biliary epithelial cells, cholangiocarcinoma cells, epithelial cells and tumour cells of the gallbladder. It seems that this humanised antibody is a useful epithelial marker for the different neoplastic lesions of epithelial cells in reptiles. The humanised anti-α-smooth muscle actin (α-SMA) antibody showed intense cross-reactivity in the smooth muscle cells of the hepatic vessels and in the muscle layer of the gallbladder. The portal myofibroblasts, the endothelial cells of the sinusoids and the stromal cells of the cholangiocarcinoma and gallbladder tumours were positive for α-SMA. The antibovine anti-vimentin and humanised anti-Ki-67 antibodies did not show crossreactivity in the different samples from the Bearded dragon. PMID:21354945

    1990-01-01

    Currently, most protocols evaluating the efficacy of gallstone lithotripsy require a visualized gallbladder on oral cholecystography (OCG). The primary purpose of the OCG is to establish that the cystic duct is patent. When the gallbladder is visualized on OCG, it can also be used to number and size gallstones accurately. Patients with non-visualization of the gallbladder on OCG are excluded from consideration for lithotripsy. The purpose of this study was to evaluate retrospectively the ultrasonographic findings (i.e., number and sizes of stones in 32 patients with nonvisualization on the OCG). In 11 patients (34%) ultrasound (US) did not detect any stone, and it is presumed that the gallbladder failed to visualize for other reasons. Six patients (19%) had one or two stones and 15 (47%) patients had more than three stones. This suggests that 20% of patients with nonvisualization of the gallbladder on OCG would otherwise be eligible for lithotripsy provided that patency of the cystic duct can be demonstrated by other means, such as computed tomographic (CT) examination with oral biliary contrast or cholescintigraphy.

    Gallbladder cancer is one of the most common cancers of biliary tract with aggressive pathophysiology, now emerging as a global health issue. Although minority of gallbladder cancer patients could receive such curative resection due to late diagnosis, this increases the survival rate. Lack of potential target molecule (s) for early diagnosis, better prognosis and effective therapy of gallbladder cancer has triggered investigators to look for novel technological or high throughput approaches to identify potential biomarker for gallbladder cancer. Intervention of non-coding RNAs in gallbladder cancer has been revealed recently. Non-coding RNAs are now widely implicated in cancer. Recent reports have revealed association of non-coding RNAs (microRNAs or miRNAs and long non-coding RNAs or lncRNAs) with gallbladder cancer. Here, we present an updated overview on the biogenesis, mechanism of action, role of non-coding RNAs, the identified cellular functions in gallbladder tumorigenesis, their prognostic & therapeutic potentials (efficacies) and future significance in developing effective biomarker(s), in future, for gallbladder.

  7. 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.

  8. Ultrasonographic findings of type IIIa biliary atresia

    International Nuclear Information System (INIS)

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

  9. Biliary ascariasis

    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.

    The use of Tc{sup 99m} ethyl hepatic iminodiacetic acid (EHIDA) imaging with cholecystokinin (CCK) in a prospective study of 115 patients with right upper quadrant biliary-type pain is described. All patients had normal US, oral cholecystography and/or endoscopy investigations. A 2-min infusion of CCK was administered at peak gallbladder uptake of EHIDA. A gallbladder ejection fraction (CBEF) was used to quantify the gallbladder response to CCK. A total of 79 of 115 patients (69%) had an abnormal GBEF ({<=}35%). Of 43 patients who underwent cholecystectomy 42 (97%) had abnormal surgical/histological findings and/or complete long-term relief of symptoms. It was concluded that Tc{sup 99m} EHIDA imaging, with a 2-min infusion of CCK and a measured GBEF {<=}35%, is highly predictive of acalculous gallbladder disease and a favourable outcome following cholecystectomy.

    Endoscopic self-expandable metal stent (SEMS) placement has become a standard palliative therapy for patients with malignant biliary obstruction. Acute cholecystitis after SEMS placement is a serious complication. We report a patient with an acute cholecystitis after covered SEMS placement, who was managed successfully with endoscopic transpapillary gallbladder drainage (ETGBD) and replacement of the covered SEMS. An 85-year-old man with pancreatic cancer suffered from acute cholecystitis after covered SEMS placement. It was impossible to perform percutaneous transhepatic gallbladder drainage. After removal of the covered SEMS with a snare, a 7Fr double pigtail stent was placed between the gallbladder and duodenum, subsequently followed by another covered SEMS insertion into the common bile duct beside the gallbladder stent. The cholecystitis improved immediately after ETGBD. ETGBD with replacement of the covered SEMS thus proved to be effective for treatment of patients with acute cholecystitis after covered SEMS placement. PMID:21403817

    Full Text Available Context Pancreatic heterotopia is a rare pathologic entity, previously reported in the stomach, duodenum and jejunum. It is mostly asymptomatic and rarely gives rise to complications. Localization of pancreatic heterotopia in the gallbladder is extremely rare and can be associated with cholecystitis or cholecystolithiasis. Case report We herein describe a case of a 39-year-old man who presented with biliary type pain with ultrasonographic evidence of a gallbladder polyp. Laparoscopic cholecystectomy was performed with uneventful recovery. Pathologic examination of the gallbladder detected a heterotopic focus of pancreatic tissue in its wall, associated with chronic cholecystitis with no gallstones. Conclusion Pancreatic heterotopia of the gallbladder is a very rare entity with unknown clinical significance. Awareness of this condition may facilitate its recognition which may shed more light on its clinical significance

    Gallbladder duplication is a rare congenital anomaly. Here, we describe a 29-year-old female who presents with classic symptoms of biliary colic. A duplicated gallbladder was recognized on preoperative ultrasound. This case report reviews a single-site robotic-assisted cholecystectomy with a cystic duct duplication. The patient underwent the surgery without complication. Due to the aberrant anatomy of the cystic triangle, it was decided to mobilize the gallbladder in a dome-down fashion. True gallbladder duplication can be categorized according to cystic duct orientation based on Boyden's classification. Preoperative diagnosis is essential to prevent surgical complications. A laparoscopic approach can be carried out safely in the hands of a skilled surgeon. This case report shows that the robotic-assisted surgical approach is a viable and safe alternative.

    Calcification of the gallbladder wall (porcelain gallbladder) is rare. Its appearance is quite characteristic on plain films, ultrasonography and computed tomography. Sporadic cases of cholecystitis have been described in porcelain gallbladders. Enterobiliary fistula may complicate acute or chronic cholecystitis in non-calcified gallbladder. We report a unusual case of acute cholecystitis with cholecystoduodenal fistula in a porcelain gallbladder. (orig.)

  15. A trial of surgical treatment in a dog suffering from severe cholecystitis associated with biliary calculus

    International Nuclear Information System (INIS)

    A miniature dachshund, 5 years and 3 months of age, with a history of cholecystitis associated with biliary calculus that had developed one year previously, presented with anorexia and vomiting. A series of examinations, including CT imaging by drip infusion cholangiography (DIC-CT), revealed that no bile was flowing into the gallbladder. Thickening of the gallbladder wall and a biliary calculus occupying the lumen of the gallbladder with a laminated internal structure were also found. Based on the results of a detailed examination, the gallbladder was extracted. E. coli and Enterococcus sp. were isolated by microbiological tests inside the gallbladder and around its outer wall. The findings of drug susceptibility tests indicated that the E. coli could be a substrate-specific, broad spectrum, beta-lactamase-producing bacterium. In this case, administration of faropenem sodium was initiated before the surgery and the postoperative course was good. DIC-CT imaging can properly visualize the biliary duct system, and an explanation that relied on these images was useful for the dog's owner. It was thought that surgical treatment should actively be considered to prevent a relapse of cholecystitis in cases involving cholecystitis associated with biliary calculi

    AIM: To further elucidate the pathogenesis and mechanisms of the high risk of gallstone formation in Crohn's disease.METHODS: Gallbladder bile was obtained from patients with Crohn's disease who were admitted for elective surgery (17 with ileallileocolonic disease and 7 with Crohn's colitis). Fourteen gallstone patients served as controls. Duodenal bile was obtained from ten healthy subjects before and after the treatment with ursodeoxycholic acid. Bile was analyzed for biliary lipids,bile acids, bilirubin, crystals, and crystal detection time (CDT). Cholesterol saturation index was calculated.RESULTS: The biliary concentration of bilirubin was about 50% higher in patients with Crohn's disease than in patients with cholesterol gallstones. Ten of the patients with Crohn's disease involving ileum and three of those with Crohn's colitis had cholesterol saturated bile. Four patients with ileal disease and one of those with colonic disease displayed cholesterol crystals in their bile. About 1/3 of the patients with Crohn's disease had a short CDT. Treatment of healthy subjects with ursodeoxycholic acid did not increase the concentration of bilirubin in duodenal bile. Several patients with Crohn's disease,with or without ileal resection/disease had gallbladder bile supersaturated with cholesterol and short CDT and contained cholesterol crystals. The biliary concentration of bilirubin was also increased in patients with Crohn's colitis probably not due to bile acid malabsorption.CONCLUSION: Several factors may be of importance for the high risk of developing gallstones of both cholesterol and pigment types in patients with Crohn's disease.

    BACKGROUND: Early diagnosis of gallbladder cancer (GBC) can remarkably improve the prognosis of patients. This study aimed to develop a nomogram for individualized diagnosis of stage I-II GBC in chronic cholecystitis patients with gallblad-der wall thickening. METHODS: The nomogram was developed using logistic re-gression analyses based on a retrospective cohort consisting of 89 consecutive patients with stage I-II GBC and 1240 patients with gallbladder wall thickening treated at one biliary surgery center in Shanghai between January 2009 and December 2011. The accuracy of the nomogram was validated by discrimina-tion, calibration and a prospective cohort treated at another center between January 2012 and December 2014 (n=928). RESULTS: Factors included in the nomogram were advanced age, hazardous alcohol consumption, long-standing diagnosed gallstones, atrophic gallbladder, gallbladder wall calciifcation, intraluminal polypoid lesion, higher wall thickness ratio and mucosal line disruption. The nomogram had concordance indices of 0.889 and 0.856 for the two cohorts, respectively. Internal and external calibration curves iftted well. The area under the receiver-operating characteristic curves of the no-mogram was higher than that of multidetector row computed tomography in diagnosis of stage I-II GBC (P CONCLUSION: The proposed nomogram improves individu-alized diagnosis of stage I-II GBC in chronic cholecystitis pa-tients with gallbladder wall thickening, especially for those the imaging features alone do not allow to conifrm the diagnosis.

  18. Inflammatory cytokines promote inducible nitric oxide synthase-mediated DNA damage in hamster gallbladder epithelial cells

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    AIM: To investigate the link between chronic biliary inflammation and carcinogenesis using hamster gallbladder epithelial cells.METHODS: Gallbladder epithelial cells were isolated from hamsters and cultured with a mixture of inflammatory cytokines including interleukin-1β, interferon-γ, and tumor necrosis factor-α. Inducible nitric oxide synthase (iNOS) expression, nitric oxide (NO) generation, and DNA damage were evaluated.RESULTS: NO generation was increased significantly following cytokine stimulation, and suppressed by an iNOS inhibitor. iNOS mRNA expression was demonstrated in the gallbladder epithelial cells during exposure to inflammatory cytokines. Furthermore, NO-dependent DNA damage, estimated by the comet assay, was significantly increased by cytokines, and decreased to control levels by an iNOS inhibitor.CONCLUSION: Cytokine stimulation induced iNOS expression and NO generation in normal hamster gallbladder epithelial cells, which was sufficient to cause DNA damage. These results indicate that NO-mediated genotoxicity induced by inflammatory cytokines through activation of iNOS may be involved in the process of biliary carcinogenesis in response to chronic inflammation of the biliary tree.

    Gallbladder tuberculosis (GT) is an extremely rare disease, and very few cases have been reported in the literature. The first case of GT was described in 1870 by Gaucher. A correct preoperative diagnosis of GT is unusual, and it is frequently confused with various gallbladder diseases. We present a new case of a patient who underwent surgery with the preoperative diagnosis of gallbladder cancer after a false positive positron emission tomography scan in the diagnostic work-up.

  20. Sonography in evaluation of gallbladder carcinoma: comparison with CT

    International Nuclear Information System (INIS)

    A total of 35 patients with gallbladder carcinoma were studied by sonography and/or computed tomography (CT) to evaluate the relative accuracy of the methods. The preoperative diagnosis was made correctly by sonography in 70% and by CT in 61%. Sonography was slightly superior to CT in diagnosing the primary tumor but this is not statistically significant. Seventeen tumors (49%) were massive type, three(9%) were thickened wall type and 15(42%) were intraluminal type. Diagnostic accuracy of sonography for each type was 33%, 78% and 73% respectively. Associated findings were direct invasion of the liver by tumor (66%), lymphadenopathy(60%), dilatation of biliary tree (37%) and gallstones (31%). Sonography was superior to CT in identifying the direct invasion into the liver and detecting gallstones whilst CT was superior to sonography in detecting lymphadenopathy. On the basis of our result, we believe that sonography and CT are complementary examinations in the evaluation of carcinoma of the gallbladder

    Full Text Available In the thesis there has been shown that biliary dyskinesia takes a leading position among hepatobiliary diseases. 54 women and 14 men aged between 19 and 64 years old, who suffered from hypo kinetic and hyper kinetic forms of dyskinesia, took part in the research. Based on the character of the functional disorders, it was defined that at hyper kinetic form of dyskinesia the best rehabilitation effects were achieved at the application of physical exercises promoting relaxation of the gallbladder, sphincter and biliary duct musculature combined with the stimulation of bile formation. It was proved that means and methods of motion therapy for patients with hyper kinetic dyskenisia had to be aimed at the restoration of the gallbladder till its full reduction. It was defined that application of different forms of therapeutic physical training considering the type of biliary dyskinesia promoted the improvement of the patients' clinical condition, motor and evacuator function of the biliary ducts.

  3. LAPAROSCOPIC ANATOMY OF THE EXTRAHEPATIC BILIARY TRACT

    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

    The pancreas, liver, and gallbladder are commonly involved in cystic fibrosis (CF), and acidic, dehydrated, and protein-rich secretions are characteristic findings. Pancreatic function studies in humans have been done by sampling the jejunal fluid. However, it has been difficult to separately study the function of pancreatic and biliary systems in humans with CF, because jejunal fluid contains a mixture of bile and pancreatic fluids. In contrast, pancreatic and biliary ducts open separately i...

    To determine the significance of anomalous position of the gallbladder. Sixteen patients with anomalous position of the gallbladder were evaluated for analysis. The diagnosis was confirmed by ultrasonography(15 patients) and oral cholecystography(1 patient). Among those, six patients underwent CT scan and a patient had 99mTc-DISIDA scan. The images were analysed with respect to the location of the GB and configuration and associated abnormality of the liver and hepatobiliary systems. Medical records of each patient were also reviewed. Among 16 patients having an anomalous position of the gallbladder, nine had retrodisplaced gallbladder, four had left-sided gallbladder, two had supra hepatic gallbladder, and one had floating gallbladder. Except for one patient, fifteen had abnormality in the liver such as focal atrophic or hypoplastic change and liver cirrhosis. Intrahepatic stones were demonstrated in 6 patients. Our results showed that anomalous position of the gallbladder was commonly associated with atrophy or hypoplasia of the liver rather than congenital in origin. The possibility of an anomalous location of gallbladder should be kept in mind when GB is not in its normal location.

  7. Ultrasonographic Findings of Gallbladder Carcinoma

    International Nuclear Information System (INIS)

    The gallbladder carcinoma accounts for 1.9% of all cancer and occurs predominantly in women over 50 years of age. As a rule, it may not be detected until the lesion has become quite large and has extended to adjacent structures. Ultrasonography is a direct imaging procedure which is widely used for the diagnosis of gallbladder carcinoma. Authors analyzed sonographic findings of 24 patients with gallbladder carcinoma diagnosed at the Department of Radiology, Kangnam St. Mary's Hospital, Catholic University Medical College during the past 5 years. 1. The gallbladder carcinoma was most prevalent in the sixth decade of life with equal ration of male to female patients. 2. The ultrasonographic findings of gallbladder carcinoma were classified into four types. The mass filling or replacing the gallbladder type was seen in 11 cases(46%), the thickened gallbladder-wall type in 6 cases (25%), fungation mass type in 4 cases(17%), and mixed type with thickened gallbladder-wall and fungating mass in 3 cases(13%). 3. Gallbladder carcinoma was associated with gallstones in 50%, with dilated bile ducts in 54%, with direct invasion of adjacent liver parenchyma in 50%, and with distant metastasis to the liver in 13%

    Definitive exclusion of biliary atresia in the infant with cholestatic jaundice usually requires operative cholangiography. This approach suffers from the disadvantage that sick infants are subjected to a time-consuming and potentially negative surgical exploration. The purpose of this study was to determine if percutaneous cholecystocholangiography (PCC) prevents unnecessary laparotomy in infants whose cholestasis is caused by diseases other than biliary atresia. This study is a 10 year retrospective review of all infants with persistent direct hyperbilirubinemia and inconclusive biliary nuclear scans who underwent further evaluation for suspected biliary atresia. A gallbladder ultrasound (US) was obtained in all patients. When the gallbladder was visualized, further imaging by PCC was done under intravenous sedation; otherwise, the standard operative cholangiogram (OCG) was performed, with liver biopsy as indicated. The primary outcome was the diagnostic accuracy of PCC, especially with respect to preventing a laparotomy. There were 35 infants with suspected biliary atresia, with a mean age of 8 weeks (range 1-14 weeks). Nine infants whose gallbladder was visualized by ultrasound underwent PCC that definitively excluded biliary atresia. Of this group, the most frequent diagnosis (five patients) was total parenteral nutrition-associated cholestasis. The other 26 infants with absent or decompressed gallbladder had laparotomy and OCG, which identified biliary atresia in 16 patients (61%). Laparotomy was avoided in all 9 patients who underwent PCC, thus reducing the negative laparotomy rate by 47%. There were no complications associated with PCC. Several alternative techniques to operative cholangiogram have been described for the definitive exclusion of biliary atresia, but many of these have distinct drawbacks. Advances in interventional radiology techniques have permitted safe percutaneous contrast evaluation of the biliary tree. Identification of a normal gall

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

    Purpose: 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.

    Full Text Available Gallbladder cancer is the most common malignant tumor of the biliary tract, and this condition has a rather dismal prognosis, with an extremely low five-year survival rate. To improve the outcome of unresectable and recurrent gallbladder cancer, it is necessary to develop new effective treatments and drugs. The purpose of the present study was to evaluate the effects of cordycepin on human gallbladder cells and uncover the molecular mechanisms responsible for these effects. The Cell Counting Kit-8 (CCK-8 and colony formation assays revealed that cordycepin affected the viability and proliferation of human gallbladder cancer cells in a dose- and time-dependent manner. Flow cytometric analysis showed that cordycepin induced S phase arrest in human gallbladder cancer cell lines(NOZ and GBC-SD cells. Cordycepin-induced apoptosis was observed using an Annexin V/propidium iodide (PI double-staining assay, and the mitochondrial membrane potential (ΔΨm decreased in a dose-dependent manner. Additionally, western blot analysis revealed the upregulation of cleaved-caspase-3, cleaved-caspase-9, cleaved-PARP and Bax and the downregulation of Bcl-2, cyclin A and Cdk-2 in cordycepin-treated cells. Moreover, cordycepin inhibited tumor growth in nude mice bearing NOZ tumors. Our results indicate that this drug may represent an effective treatment for gallbladder carcinoma.

    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.

  19. Biliary scanning with /sup 99m/Tc pyridoxylideneglutamate. The effect of food in normal subjects: concise communication

    International Nuclear Information System (INIS)

    Technetium-99m pyridoxylideneglutamate biliary scans were performed in 19 normal subjects in both the fasted and nonfasted state. The effect of eating was to reduce visualization of the gallbladder from 100% (fasted) to 47% (nonfasted). The common bile duct was seen in 84% on both occasions but intrahepatic and cystic ducts were seen less frequently in the nonfasted group. Preparation of patients by fasting is essential if information concerning gallbladder function is sought

    Of the 20 cases with biliary colics who had normal OCG and ultrasound, 11 (55%) showed microlithiasis in the form of cholesterol monohydrate crystals and/or calcium bilirubinate granules on polarized light microscopy of the duodenal bile. Microlithiasis was noted in gallbladder bile of all (100%) the cases with proven gallstones but in none of the duodenal bile samples from healthy subjects. This study suggests that polarized microscopy may be a useful method to detect microlithiasis in patients with repeated biliary colics who have normal OCG and ultrasound examination. PMID:2815325

  1. Biliary motor function evaluated with MRI after administration of a fat diet

    International Nuclear Information System (INIS)

    Subjects were given a fat diet and dynamic magnetic resonance cholangiography (dynamic MRC) studies were performed. Gallbladder contractile ratio and bile excretion capacity were evaluated as indices of bile stasis, by correlation with the biochemical examination data. The effectiveness of dynamic MRC examination was discussed. The subjects included 10 healthy volunteers and 40 gallstone patients. Before and after loading with the fat diet, gallbladder volume was measured by US and MRI. Further, the number of bile excretion episodes was measured by dynamic MRC. We evaluated whether a significant difference was seen in gallbladder contraction ratios and change in number of bile excretion episodes between examinations in the presence or absence of gallstones. We also investigated whether there was a correlation among the gallbladder contraction ratios and change in number of bile excretion episodes between examination vs. T-Bil value, γ-GTP value and ALP value respectively. The gallbladder contraction ratios and change in number of bile excretion episodes between examinations were significantly reduced in gallstone patients in comparison to healthy subjects. There was no correlation among the gallbladder contraction ratios and change in number of bile excretion episodes between examinations vs. T-Bil, γ-GTP and ALP. Dynamic MRC enabled noninvasive calculation of the gallbladder contraction ratios under conditions similar to physiological conditions and also evaluation of the bile flow in a dynamic manner. The gallbladder contraction ratios and bile excretion capacity measured by MRI can evaluate biliary motor function which indicated another aspect of the biochemical examination. (author)

  2. 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.

    The purpose of this study is to evaluate that sequential CT scans after oral contrast ingestion can show morphological and functional status of the biliary tree, especially for the gallbladder and assess whether the CT scans demonstrate other radiological information than conventional oral cholecystography. Thirty volunteers in third decades and eight patients with hepatobiliary disease were included for the study. CT scans were obtained 3, 6, 9, 12 hours after oral contrast ingestion and thirty minutes after fat meal in thirty volunteers. Conventional oral cholecystography was also obtained in all volunteers at 12 hours after oral contrast ingestion and after fat meal. We evaluate opacification of gallbladder, biliary tree, and duodenum by contrast media on CT scans and attenuation values of gallbladder, common hepatic duct and common bile duct in each anatomic area on CT and its sequential change. CT scans were performed 6 hours after oral contrast ingestion in eight patients with hepatobiliary disease. And gallbladder function was evaluated by opacification of gallbladder by contrast media in all patients. In thirty volunteers, opacified gallbladder by contrast media was seen in all cases in all sequential periods of time on CT scans, but in 22 cases on conventional oral cholecystography. Contrast-filled intrahepatic ducts were demonstrated in 3 cases at 3 hours after oral contrast ingestion and 11 cases at 6 hours and were not seen thereafter. Contrast-filled common hepatic duct was noted in 28, 18 and 4 cases respectively at 3, 6 and 9 hours after oral contrast ingestion and the CT attenuation values of common hepatic ducts had become progressively decreased. Contrast-filled common bile duct was noted in 28, 18 and 4 cases respectively at 3, 6 and 9 hours and the CT attenuation values of common bile ducts were not changed until 9 hours but slightly increased at 12 hours. Contrast media was noted in 7, 5, 6 and 5 cases at 3, 6, 9 and 12 hours in cystic duct and

  5. Imaging diagnosis of biliary tract lesions (with a report of 486 cases)

    International Nuclear Information System (INIS)

    Objective: To evaluate the various imaging modalities in the diagnosis of biliary tract lesions. Methods: The imaging findings of 486 cases of biliary tract lesions proved surgically and pathologically were retrospectively reviewed. The advantage and the limitation of each examination were analyzed. Results: Twenty six cases with negative stone in gallbladder were demonstrated in conventional cholecystography. The anatomical morphology and the pathogenesis were well shown on direct cholangiography. The positive accuracy of ultrasonography (US) and CT for biliary duct calculus was 91.3% and 90.3%, respectively. Sanded stone were missed on CT in 13 cases. The consistent rate of US diagnosis of chronic cholecystitis and gallbladder polyps was 100% and 93.3%, respectively. The 'bile duct tree' at MRCP helped the diagnosis of the cholangiocarcinoma arising at the portal hepatics. Conclusion: The negative stone in gallbladder can be demonstrated by conventional cholecystography. Direct cholangiography can provide important evidence for the qualitative diagnosis. US and CT are superior to other modalities in detecting biliary duct calculus. US is the best imaging modality for chronic cholecystitis and polypoid lesion of gallbladder. 3D MRCP is an ideal imaging for severe bile duct obstruction

    Full Text Available Introduction Acute calculous (obstructive cholecystitis develops as a consequence of cystic obstruction and obstruction of bile flow into choledochus. Most often it is a result of impacted gallstones in Hartman's pouch or the cystic duct. Their direct pressure on gallbladder mucosa causes ischemia, necrosis and ulceration with consequential wall edema and obstructed venous flow. This mechanism is further increasing and spreading the inflammatory process. Ulcerations may be that extensive, that mucosa is highly recognizable on the microscopic preparation. Leukocyte infiltration of all segments occurs. Results of necrosis are as follows: perforation with pericholecystic abscess formation, fistulization or biliary peritonitis. Aim The aim of this investigation was to use microbial sensitivity tests in order to establish possibilities of antibiotic therapy in patients with acute cholecystitis. Material and methods Using random sampling a total of 240 patients with acute cholecystitis were included in the investigation. They were all treated at the Clinic of Abdominal and Endocrine Surgery of the Clinical Center Novi Sad in the period 1997-1999. All patients underwent bacteriological examination and were coherent in regard to sex and age. Microbial sensitivity tests analyzed two groups of bacteria: Group I Escherichia coli, Klebsiella and Staphylococcus and Group II: other isolated bacteria (Citrobacter, Enterobacter, Enterococcus, Proteus, Pseudomonas Serratia and Streptococcus. Results In our material Escherichia coli was isolated in most patients - 32 (55.17%, Klebsiella and Staphylococcus in 6 (10.34% patients and Streptococcus in 4 (6.90%, whereas other bacteria were infrequent (Citrobacter and Serratia in 3.45%, Enterobacter, Proteus and Pseudomonas in 1.75%. Thus, E. coli, Klebsiella and Staphylococcus were established in 75.85% of bacteriologic findings, and all the rest in 24.15%. Assessment regarding premedication with antibiotics started

  8. Apparent gut excretion of Tc-99m-DISIDA in case of extrahepatic biliary atresia

    International Nuclear Information System (INIS)

    Patient had DISIDA scan at 39 days of age to exclude biliary atresia. Gut excretion was seen 18 h after injection and the diagnosis of neonatal hepatitis was made. Because of continued elevated liver function values, liver biopsy was performed and demonstrated findings consistent with biliary atresia. Exploratory laparotomy performed 8 days after the scan showed patient cystic duct, bule duct, and gall-bladder, but an atretic common hepatic duct. This case is an example of documented biliary atresia demonstrating gut excretion on the DISIDA scan. (orig.)

    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.

Improvement of early diagnosis is of great significance to prolong the survival. Risk factors for gallbladder cancer include gallstones, cholelithiasis, anomalous pancreaticobiliary junction, focal mucosal microcalcifications, and et al.Advances in endoscopic ultrasonography, magnetic resonance cholangiopancreatogram and helical computed tomography have enhanced preoperative diagnosis of gallbladder cancer. Understanding the characteristics of gallbladder cancer with the help of multiple imaging modalities can facilitate accurate diagnosis and may also help in sorting patients to undergo extended resection or an alternative therapy. Resection is currently the most effective and only potentially curative treatment for gallbladder cancer.However, owing to its non-specific symptoms, gallbladder cancer patients often suffer from late diagnosis, and few patients are suitable for surgery. Other treatment strategies such as chemotherapy, radiotherapy, percutaneous biliary drainage, palliative surgery are used in patients with advanced gallbladder cancer.For jaundiced gallbladder cancer patients, preoperative biliary drainage is still under debate. Since biliary inflammation adversely affects the prognosis of gallbladder cancer patients,antibiotics with high concentration in bile is recommended for selected patients.

  14. 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)

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

    Full Text Available Abstract Hepatoid adenocarcinoma is a rare variant of extrahepatic adenocarcinoma which behaves like hepatocellular carcinoma in morphology and functionality. We present a rare case of hepatoid adenocarcinoma of the gallbladder which invades deeply the liver bed, in a 59-year-old woman. Histologically, most of the mass in the gallbladder was composed of cells with eosinophilic cytoplasm arranged in a trabecular pattern, which resembled hepatocellular carcinoma. The main differential diagnosis was hepatocellular carcinoma with invasion into the gallbladder. The gallbladder origin of the hepatoid adenocarcinoma was verified by the presence of foci of conventional adenocarcinoma, the recognition of high-grade dysplasia in the adjacent epithelium and the absence of cirrhosis.

  19. The effect of different dosing regimens of motesanib on the gallbladder: a randomized phase 1b study in patients with advanced solid tumors

    International Nuclear Information System (INIS)

    Gallbladder toxicity, including cholecystitis, has been reported with motesanib, an orally administered small-molecule antagonist of VEGFRs 1, 2 and 3; PDGFR; and Kit. We assessed effects of motesanib on gallbladder size and function. Patients with advanced metastatic solid tumors ineligible for or progressing on standard-of-care therapies with no history of cholecystitis or biliary disease were randomized 2:1:1 to receive motesanib 125 mg once daily (Arm A); 75 mg twice daily (BID), 14-days-on/7-days-off (Arm B); or 75 mg BID, 5-days-on/2-days-off (Arm C). Primary endpoints were mean change from baseline in gallbladder size (volume by ultrasound; independent review) and function (ejection fraction by CCK-HIDA; investigator assessment). Forty-nine patients received ≥1 dose of motesanib (Arms A/B/C, n = 25/12/12). Across all patients, gallbladder volume increased by a mean 22.2 cc (from 38.6 cc at baseline) and ejection fraction decreased by a mean 19.2% (from 61.3% at baseline) during treatment. Changes were similar across arms and appeared reversible after treatment discontinuation. Three patients had cholecystitis (grades 1, 2, 3, n = 1 each) that resolved after treatment discontinuation, one patient developed grade 3 acute cholecystitis requiring cholecystectomy, and two patients had other notable grade 1 gallbladder disorders (gallbladder wall thickening, gallbladder dysfunction) (all in Arm A). Two patients developed de novo gallstones during treatment. Twelve patients had right upper quadrant pain (Arms A/B/C, n = 8/1/3). The incidence of biliary “sludge” in Arms A/B/C was 39%/36%/27%. Motesanib treatment was associated with increased gallbladder volume, decreased ejection fraction, biliary sludge, gallstone formation, and infrequent cholecystitis.

    Sonographic images of the gallbladder enable satisfactory approximation of gallbladder volume using the sum-of-cylinders method. The sum-of-cylinder measurements, however, are moderately cumbersome and time consuming to perform. In this investigation, in vitro and in vivo testing was done to determine that a simple ellipsoid method applied to sonographic gallbladder images yields reasonable volume approximations that are comparable to the volumes calculated by the sum-of-cylinders method. Findings from a water-bath experiment showed that measurement of gallbladder volume by the ellipsoid method closely approximated the true volume with a mean difference of about 1.0 ml. The results of in vivo studies in five volunteers demonstrated that the gallbladder contracted substantially after a fatty meal and that volumes calculated by the ellipsoid and sum-of-cylinders methods were nearly identical. Thus, a simple ellipsoid method, requiring negligible time, may be used to approximate satisfactory gallbladder volume for clinical or investigative studies. PMID:3901703

    Full Text Available Gallbladder cancer is generally diagnosed at an advanced stage. The liver is the mostcommonly invaded organ by direct extension and/or metastasis, followed by regional lymphnodes. Oral soft tissue metastasis is extremely unusual. This report describes the case of a62-year-old woman diagnosed with advanced metastatic gallbladder cancer, who initiallypresented with abdominal pain. Diagnosis of gallbladder cancer was made about 3 monthsafter her symptoms developed, when a laparoscopic cholecystectomy was performedbecause of the suspicion of gallstones. Liver metastasis was also discovered during surgery.A postoperative investigation revealed additional lung and bone metastases. A visible leftgingival tumor was found on physical examination and was confirmed as gallbladder cancermetastasis by compatible histopathology 1 month after surgery. The patient responded poorlyto chemotherapy and unfortunately died 5 months after the diagnosis. The clinical presentationof gallbladder cancer was relatively typical, apart from the unusual gingival metastasis.The medical literature contains quite a few examples of metastatic lesions locatedstrictly in the oral soft tissue, however no case of gallbladder cancer metastasizing to theoral soft tissue has been previously reported.

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

    Although the ultrasonography has been regarded as a main procedure in the diagnosis of bile duct and gallbladder diseases, a few reports concerning the ultrasonographic findings of biliary ascariasis appeared in the literature. Seven cases of real-time ultrasonographic diagnosis of biliary ascariasis were made in our hospital during last 15 months. In six, the diagnosis was confirmed by surgery or radiographic examination. The results were as follows: 1. The characteristic long, thick, highly reflective echo without distal acoustic shadowing in the extra- and/or intra-hepatic ducts were seen in all six proven cases. 2. The echogenic, nonshadowing images of the worms were seen as single stripe in five cases (containing a central, longitudinal, anechoic tube, suggesting its digestive tract in three cases) or multiple stripes in one case. But so-called coiled appearance or amorphous fragments were not seen in our cases. 3. Associated findings were as follows: mild to moderate dilatation of the extrahepatic duct in all six proven cases, mild dilatation of the intrahepatic ducts in 3 cases, mild dilatation of the pancreatic duct in 1 case, intrahepatic stone in 1 case, contracted gallbladder containing single stone in 1 case and evidence of cholecystitis in 4 cases. 4. One false positive diagnosis of ascariasis in the gallbladder is considered due to reverberation artefact. No false negative was seen.

    Porcelain gallbladder is a rare disorder by deposition of calcium in the wall of gallbladder. The chronic cholecystitis is reported to produce mural calcification and obstruction to the cystic duct by stone. Since porcelain gallbladder is commonly associated with gallbladder cancer, cholecystectomy is performed to prevent it. We report here a case of a patient with porcelain gallbladder. This case showed the typical ultrasonographic, computer tomographic and radiographic findings of the disease.

    BACKGROUND: Pancreaticobiliary maljunction is a high risk factor of pancreatitis and biliary tract cancer. How this mal-junction affects the liver remains obscure. This study aimed to examine the effects of pancreaticobiliary maljunction on the liver, pancreas and gallbladder in a cat model. METHODS: A model of choledocho-pancreatic side-to-side ductal anastomosis was created in ten cats.Before the procedure, a small piece of tissue from the liver, pancreas and gallbladder was collected as a control. The common channel formation was checked by cholecystography. The livers, pancreases and gall-bladders of these cats were harvested for histological examina-tion. The expression of proliferating cell nuclear antigen in the gallbladder was examined with immunohistochemistry. RESULTS: Seven of the 10 cats survived for 6 months after surgery. The color of the liver was darker in the PBM model than the control specimen, with nodules on the surface. His-tological examination showed ballooning changes and inflam-matory infiltrations and the histopathological score increased significantly (P CONCLUSION: The present study demonstrated that pancreatico-biliary maljunction can lead to the injuries of the liver, pancreas and gallbladder.

    The effectiveness of ultrasound, computed tomography, hepatobiliary scintigraphy and nuclear magnetic resonance in diseases of the biliary tract is described. Ultrasound should be the first examination in clinical suspicion of cholelithiasis and has a higher accuracy than oral cholecystography. Computed tomography is very expensive and should be carried out in suspected gallbladder carcinoma, cholecystitis with abscess formation, tumour in the porta hepatis and pancreatic head and in sonographically unclear cases. Nuclear magnetic resonance can determine the ability of the gallbladder to concentrate bile. Ultrasound can distinguish with high accuracy between obstructive and inflammatory jaundice. In clinical suspicion of bile duct lesions an infusion cholangiogram must be carried out, if bilirubin is lower than 5 mg%; if bilirubin is higher, an ERC or PTC should be performed. If in biliary obstruction a suspicion of tumour in porta hepatis or head of the pancreas is present, computed tomography should be effected.

    No study has reported an association between gastroesophageal reflux disease (GERD) or its therapies and gallbladder function. We compared pre- and postoperative gallbladder function in patients undergoing fundoplication to determine the following: (1) whether patients with chronic GERD have preexisting gallbladder motor dysfunction; (2) whether medical or surgical therapy alters gallbladder function; and (3) whether division of the hepatic branch of the anterior vagus nerve is detrimental to gallbladder motility. Nineteen patients with documented GERD consented to a preoperative cholecystokinin-stimulated technetium hepatobiliary (CCK-HIDA) scan to quantify the gallbladder ejection fraction (GBEF). All patients underwent laparoscopic Nissen fundoplication. One month after fundoplication, 12 patients completed a repeat CCK-HIDA scan for determination of GBEF, with comparison to the preoperative GBEF. Among patients with preoperative GERD, 11 (58%) of 19 met the scintigraphic criteria for gallbladder dysfunction (GBEF hepatic branch of the anterior vagus nerve and postoperative gallbladder dysfunction (P = NS, chi-square test). Unexpectedly, 58% of patients with GERD demonstrated gallbladder motor dysfunction prior to fundoplication, with improvement to normal occurring in most of those studied postoperatively. These data support controlled trials to determine the effect of chronic GERD and antisecretory therapy on gallbladder and global gastrointestinal smooth muscle function. Preservation of the hepatic branch of the anterior vagus nerve during fundoplication offered no clear benefit with regard to early postoperative gallbladder function. PMID:12504218

    Full Text Available Abstract Previous studies have shown a positive association between chronic typhoid carriage and biliary cancers. 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.

    Purpose: The aim of this retrospective study was to evaluate the diagnostic value of CT features of the gallbladder in the prediction of gallstone pancreatitis. Materials and methods: Eighty-six patients who underwent a diagnostic computed tomography (CT) scan for acute pancreatitis were included. The readers assessed the presence of pericholecystic increased attenuation of the liver parenchyma, enhancement of gallbladder (GB) and common bile duct (CBD) wall, pericholecystic fat strands, GB wall thickening, stone in the GB or CBD, and focal or diffuse manifestations of pancreatitis on abdominal CT scans. In addition, the maximal transverse luminal diameters of the GB and CBD were measured. Results: The presence of pericholecystic increased attenuation of the liver parenchyma, GB wall enhancement and thickening, pericholecystic fat strands, stone in the GB or CBD, and diffuse manifestations of pancreatitis achieved statistical significance for differentiation of gallstone induced pancreatitis from non-biliary pancreatitis (p < 0.05). The mean values of maximal transverse luminal diameter of GB and CBD were significantly higher in gallstone induced pancreatitis group (39.67 {+-} 7.26 mm, 10.20 {+-} 4.13 mm) than non-biliary pancreatitis group (27.01 {+-} 6.14 mm, 3.85 {+-} 2.51 mm, p < 0.0001). Conclusion: Gallbladder features of CT in patients with pancreatitis could be the valuable clues for the diagnosis of gallstone induced pancreatitis.

  18. Carcinogenesis of gallbladder mucosa with occult pancreatobiliary reflux

    International Nuclear Information System (INIS)

    Characteristics of gallbladder cancer (GC) with occult pancreatobiliary reflux (OPBR) were retrospectively examined with images by US (ultrasonography), endoscopic US (EUS), ERCP (endoscopic retrograde cholangiopancreatography) and multi-row CT, and with pathological specimens of the mucosa to consider its carcinogenesis. Subjects were 51-77 years old, 7 female patients with GC in whom OPBR was suggested mainly by mucosal hypertrophy in those images. Pathological observation was performed on specimens stained by HE and Ki-67 (for detecting cell proliferation). Imaging and pathological findings of the mucosa in the present GC were found analogous to known characteristics of GC with abnormal pancreatbiliary confluence, suggesting a similar carcinogenetic process to each other, where biliary phospholipids (PL) were degraded to toxic lyso-PL and free fatty acids. The subject with OPBR could thus be classified in the high risk group. More cases in number were thought necessary to define the surgical treatment, its timing and procedure in GC. (R.T.)

    Changes in the radiological diagnosis of gallbladder disease are occurring at a remarkable rate. In this symposium, several recognized authorities place the various diagnostic modalities and their interrelation in modern perspective. The present and future roles of oral cholecystography and intravenous cholangiography, the radiological diagnosis of chronic acalculous cholecystits, and the use of ultrasonography and cholescintigraphy are analyzed.

  1. Mutational profiling reveals PIK3CA mutations in gallbladder carcinoma

    International Nuclear Information System (INIS)

    The genetics of advanced biliary tract cancers (BTC), which encompass intra- and extra-hepatic cholangiocarcinomas as well as gallbladder carcinomas, are heterogeneous and remain to be fully defined. To better characterize mutations in established known oncogenes and tumor suppressor genes we tested a mass spectrometric based platform to interrogate common cancer associated mutations across a panel of 77 formalin fixed paraffin embedded archived BTC cases. Mutations among three genes, KRAS, NRAS and PIK3CA were confirmed in this cohort. Activating mutations in PIK3CA were identified exclusively in GBC (4/32, 12.5%). KRAS mutations were identified in 3 (13%) intra-hepatic cholangiocarcinomas and 1 (33%) perihillar cholangiocarcinoma but were not identified in gallbladder carcinomas and extra-hepatic cholangiocarcinoma. The presence of activating mutations in PIK3CA specifically in GBC has clinical implications in both the diagnosis of this cancer type, as well as the potential utility of targeted therapies such as PI3 kinase inhibitors

    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

    2008-01-01

    The limited efficacy of cytotoxic therapy for advanced biliary tract and gallbladder cancers emphasizes the need for novel and more effective medical treatment options. A better understanding of the specific biological features of these neoplasms led to the development of new targeted therapies, which take the abundant expression of several growth factors and cognate tyrosine kinase receptors into account. This review will briefly summarize the status and future perspectives of antiangiogenic and growth factor receptor-based pharmacological approaches for the treatment of biliary tract and gallbladder cancers. In view of multiple novel targeted approaches, the rationale for innovative therapies, such as combinations of growth factor (receptor)-targeting agents with cytotoxic drugs or with other novel anticancer drugs will be highlighted.

    Four patients who complained of symptoms and signs compatible with biliary tract disease and in whom the diagnosis of gallbladder (three cases) and common bile duct ascariasis (one case) was made sonographically are reported. In two patients with gallbladder ascariasis, cholecystectomy corroborated the presence of the round-worms, and was curative. The third patient was a pregnant woman (32nd gestational week) who took piperazine citrate, and a second sonogram performed 29 days later was completely normal. The fourth patient with common bile duct ascariasis underwent choledochotomy with extraction of one ascaris lumbricoides from the common duct, and a T tube was left in place for 15 days. All patients received antiparasitics and had a favorable outcome. Ultrasonography is an important noninvasive diagnostic procedure in the work-up of these patients, who usually describe a clinical picture suggesting gallstone disease: this is especially true in the presence of pregnancy.

    2015-01-01

    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.

    Abstract Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

  12. 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

    Full Text Available Our objective is to report three patients with recurrent severe upper abdominal pain secondary to residual gallbladder. All patients had been subjected to cholecystectomy from 1 to 20 years before. The diagnosis was established after several episodes of severe upper abdominal pain by imaging exams: ultrasonography, tomography, or endoscopic retrograde cholangiography. Removal of the residual gallbladder led to complete resolution of symptoms. Partial removal of the gallbladder is a very rare cause of postcholecystectomy symptoms.

    Objective To clarify the relationship between loss of expression of DPC4 proteins and pathogenesis of biliary tract carcinoma. Methods 71 primary biliary tract carcinomas(BTCa),including 38 common bile duct(CBD) carcinomas,18 gallbladder carcinomas,and 15 hilar bile ducts(HBD) carcinomas were examined by immunohistochemical staining .In addition,the CBD carcinomas were divid-ed into two groups,a trmor group with metastasis(M+ group ,27 cases)and a tumor group without metastasis(M-group,11 cases). Results The frequency of loss expression of DPC4 protein was 32.8% in BTCa ,47.3% in CBD carcinoma ,11% in gallbladder carcino-ma and 13% in HBD carcinoma.A comparison of the frequency of loss expression of DPC4 showed singnificantly statistical difference in the CBD carcinoma versus gallbladder carcinoma and HBD carcinoma (P0.05). Conclusion There is a close relationship between the pathogenesis of BTCa and inactivation of DPC4 with different frequencies of DPC4 gene alteration in various locations of the biliary tract,but inactivation of DPC4 is not related with tumor metastasis in BTCa.

    Introduction Acute calculous (obstructive) cholecystitis develops as a consequence of cystic obstruction and obstruction of bile flow into choledochus. Most often it is a result of impacted gallstones in Hartman's pouch or the cystic duct. Their direct pressure on gallbladder mucosa causes ischemia, necrosis and ulceration with consequential wall edema and obstructed venous flow. This mechanism is further increasing and spreading the inflammatory process. Ulcerations may be that extensive, th...

    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

    A 7-year-old, male, castrated, Labrador Retriever with a history of pancreatitis and inflammatory bowel disease presented for vomiting and anorexia. Serum biochemistry findings were indicative of cholestasis, hepatocellular insult, and decreased hepatic function. Ultrasound examination showed sediment and gas within the gallbladder, and a diagnosis of emphysematous cholecystitis was made. Emergency gallbladder resection was performed. Cytologic examination of bile fluid collected at surgery showed a mixed population of bacteria (bactibilia) together with fungal organisms consistent with Cyniclomyces guttulatus (previously known as Saccharomycopsis guttulatus). Similar fungal organisms were seen on a fecal smear. Bacteria cultured were normal gastrointestinal flora, supporting ascending infection; the fungal organisms were interpreted as incidental. Histopathology of the gallbladder indicated active (suppurative) and chronic (lymphocytic) cholecystitis and sections of liver tissue had evidence of chronic liver disease. A positive liver culture indicated concurrent bacterial hepatitis or cholangiohepatitis. Despite supportive care, the dog continued to decline and was euthanized 30 days later. Necropsy results confirmed end stage liver disease, but an initiating cause was not found. This case highlights the role of bactibilia in the development of acute cholecystitis and the unique cytologic appearance of C guttulatus as an incidental finding in bile fluid. PMID:17123257

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

    Directory of Open Access Journals (Sweden)

    Pavel Strnad

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

  20. 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.

    We present an extremely unusual case of an external biliary fistula in an 87-year-old woman who presented with a 1-day history of spontaneous green discharge from a 60-year-old appendicectomy scar. Examination revealed a sinus in the right iliac fossa overlying her appendicectomy scar, with a raised white cell count and C reactive protein. A CT scan revealed a complex fistula connecting the gallbladder to the subcutaneous tissue in the right flank, which further connected inferiorly with a fistula to the previous appendicectomy scar and a small iliopsoas collection. Endoscopic retrograde cholangiopancreatography revealed several stones in the common bile duct, which were removed using a balloon catheter. The patient was further managed with a long course of antibiotics and discharged with a long-term drainage bag. A literature search revealed no previously reported cases of an external biliary fistula communicating with an appendicectomy scar. PMID:27073150

    Gallbladder and biliary tract cancer is a serious clinical problem. In-spite of wide range of new diagnostic and therapeutic methods, the significant improvement of treatment results, has not been noticed so far. The research about prevention methods, seems to be important, among the ways of improvement of the diagnosis and therapy outcomes of these diseases. It is related for example to study about one of the cause of biliary tract carcinogenesis--the imbalance between production of reactive oxygen species (ROS) and their inactivation by the antioxidative barrier. One of the components of this organism protection complex are antioxidative vitamins. The aim of this study was to measure the concentration of antioxidative vitamins (A, C, E, and beta-carotene) in serum, in patients with cancer of gallbladder and and biliary tract, in comparison to the results of healthy volunteers. The study groups comprised of 56 patients, both sexes with acute and chronic cholecystitis and with above-mentioned neoplasmas. The results shoved, that concentration of antioxidative vitamins in serum of patients with gallbladder and biliary tract cancer, was significantly decreased. The outcomes of this research, seem to confirm the participation of antioxidative barrier in inhibition of carcinogenesis of in those important parts of digestive system. PMID:17679377

  3. Percutaneous transhepatic biliary drainage

    International Nuclear Information System (INIS)

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

    The author encountered 36 cases of the cholecystopathy confirmed by the operation or I.V. cholecystography after the plane films of abdomen were taken, and who were admitted through the emergency room at Busan National University and Busan Saint Benedict Hospitals from January 1977 to October 1978. Among them, the author analyzed especially 10 cases of the cholecystopathy showed the gallbladder shadow on the plain films of the abdomen and confirmed by the operation. After then, 104 cases of normal persons as a control group were taken the plain film study of the abdomen with the supine and erect positions. The findings obtained through this study were summarized as follows. 1. Among 36 cases of the cholecystopathy, the age distribution was 19 to 77 years of age, and the highest incidence was fifth decade. Sex ratio was equal in distribution.2. The most prominent symptom was right upper abdominal pain (97.2%). Then came radiating pain, fever, chilling, nausea, vomiting, and jaundice in that order. 3. The most common duration of the clinical onset was less 5 days. 4. The radiographic film of plain abdomen showed local meteorism in 91.7%, gallbladder shadow in 47.2%, and radiopaque gall stone, air in gallbladder and air in biliary duct in 2.7%, respectively. 5. In the control group, no gallbladder shadow and air in small intestine were seen on the radiographic films of plain abdomen, but some of the air shadow in hepatic and splenic flexures of colon were found in about 90.4% or more. 6. The diameters of the gallbladder shadow showed from 3.5 cm to 8,5 cm in width on the radiographic films of plain abdomen. The operative findings showed a severe inflammatory change in the wall of gallbladder, but no gall stone in the smaller cases of the gallbladder shadow. In the large cases, a single or multiple radiolucent stones in common bile duct or gall bladder, or tumor in common bile duct with inflammatory change in the call of gallbladder were found. 7.

    Full text: We have previously shown that image registration, based upon a two-dimensional cross-correlation (CC) of logarithmic Laplacian images (LLI), corrected motion in biliary studies in up to 90% of cases with minimal artifact. We have now applied the same technique to gastric emptying studies (GES). GES were acquired on an LFOV gamma camera over a two-hour period as 20-26 pairs of anterior-posterior frames (30 second duration and 64 x 64 matrix) for both solid and liquid components. All images were manually registered so that the solid contents of the stomach lay within an operator-drawn ROI. The anterior images of the solid component for 30 randomly selected patients were subjected to further image registration using CC of LLI, CC of raw images (Rl) (a common approach to image registration) and CC of Laplacian images (Ll). All images were aligned to the third image of the study, on which an ROI was drawn to outline the stomach. The number of images in which stomach counts appeared outside this ROI were tallied, in the original and all re-registered studies. Maximum displacements in X/Y position between images of studies registered by the LLI and Rl methods were also computed to directly compare positional accuracy. Stomachs partially exceeded the limits of the ROI in 27, 9, 53 and 54 frames (total of 710) in the original, LLI, Rl and Ll studies respectively. There were 4, 1, 6 and 7 studies with misregistered stomachs on more than 2 frames. Frames in seven Rl studies differed from the LLI studies in X/Y position by 3 pixels or more. Cross-correlation using LLI was the only method which improved upon the original manual registration. The Rl and Ll methods increased the number of misregistered frames. We conclude that in gastric emptying studies, as in biliary studies, object tracking by CC of LLI is the method of choice for image registration.

    Choledochal cyst is a relatively rare condition. Even rarer is a choledochal cyst in association with a gallbladder carcinoma. This study reports a rare case of gallbladder carcinoma coexisting with a choledochal cyst in a Nigerian patient. Clinical records of the patient including preoperative evaluation, intraoperative findings, and postoperative care were reviewed. A 38-year-old woman presented with the recurrent right upper abdominal pain of 3 years duration associated with progressive weight loss, anorexia, recurrent vomiting, as well as, low-grade fever with chills and rigors. Physical examination revealed an anicteric woman with tenderness in the right hypochondrium and a positive Murphy's sign. A combination of abdominal ultrasound and computed tomography scan suggested a Type IV choledochal cyst and a distended gallbladder with thickened walls containing a heterogeneous hyperdense mass. Preoperative serum alkaline phosphatase was elevated while endoscopic retrograde cholangiopancreatography was inconclusive. At laparotomy, extrahepatic biliary dilatation and enlarged, the nodular gallbladder was found with a diffusely fibrotic pancreas. Intraoperative cholangiogram confirmed Type IV choledochal cyst. Excision of the common bile duct and radical cholecystectomy was performed, and a Roux-en-Y hepaticojejunostomy. Histopathology confirmed the diagnosis of gallbladder adenocarcinoma. She had adjuvant chemotherapy and is presently on follow-up. No evidence of recurrence after 5 years of follow-up. A high index of suspicion is required to detect a combination of these two rare entities. When detected, both conditions should be surgically addressed at the same sitting, and when combined with adjuvant chemotherapy, may increase the chances of achieving a cure. PMID:27013859

    Cholelithiasis is the most common affliction of the gallbladder and biliary tract. Including its complications, gallstone disease represents the basis for cholecystitis and cholangitis in the majority of cases. Inflammatory diseases of the biliary system are divided into acute and chronic forms originating from the gallbladder as well as from the biliary tract. Although acute calculous cholecystitis is the most common form, gangrenous, and emphysematous inflammation of the gallbladder as well as gallbladder empyema are included in this group of diseases. In the chronic forms, calculous and acalculous inflammation is also differentiated. Recent developments in cross-sectional imaging in sonography, computed tomography, and magnetic resonance imaging offer numerous tools for depicting the biliary system with high diagnostic accuracy. Invasive imaging modalities of the biliary system are mainly used for therapeutic aspects. (orig.) [German] Die Cholelithiasis ist die haeufigste Erkrankung von Gallenblase und Gallenwegen.

    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

    International Nuclear Information System (INIS)

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

  11. An incidental case of biliary fascioliasis with subtle clinical findings: US and MRCP findings

    International Nuclear Information System (INIS)

    Fascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare. We present unique ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) findings of a biliary fascioliasis case which doesn’t have biliary obstruction or cholestasis. Radiologically, curvilinear parasites compatible with juvenile and mature Fasciola hepatica within the gallbladder and common bile duct were found. The parasites appear as bright echogenic structures with no acoustic shadow on US and hypo-intense curvilinear lesions on T2 weighted MRCP images. Imaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions

    Whole-body I-MIBG images were acquired in a 12-year-old girl who had metastatic malignant paraganglioma to assess the extent of the metastases. Image quality was suboptimal because of diffusely increased muscle activity, which was related to the labetalol the patient took to control her blood pressure. Despite the suboptimal images, a subtle activity in the lower border of the liver was noted, along with known lesions in the sacrum and upper chest. Further SPECT/CT images localized this activity in the gallbladder. PMID:26914576

    Biliary adenomas that are usually found in surgically removed gallbladders are rare, but can also occur in the extrahepatic biliary tree. We present a case series of extrahepatic bile duct adenomas at our institution, along with a review of the literature. All three patients with extrahepatic biliary adenomas (two in the common bile ducts, one in the hepatic duct) were female with a mean age of 74 years. On initial presentation, none of the patients had obstructive jaundice but two of the three patients had symptoms of biliary origin. Case 1 is an 85-year-old woman with an incidental biliary dilation seen on chest imaging; endoscopic ultrasound revealed a sessile adenomatous polyp in the distal bile duct. The patient refused surgery and presented with occlusive biliary stricture and jaundice 5 months after initial presentation, with cytology confirming malignant progression. Case 2 is a 78-year-old woman with a history of primary sclerosing cholangitis and who presented with cholangitis, and Gram-negative sepsis. A polypoid lesion was seen on imaging in the common hepatic duct and direct cholangioscopy with biopsies confirmed the presence of adenoma with high grade dysplasia. The patient underwent successful total bile duct resection and hepaticojejunostomy but represented 1 year later with diffuse metastatic disease to the bone, liver, and peritoneum. Case 3 is a 61-year-old woman who presented with symptoms suggestive of gallbladder pathology and was found to have a polypoid bile duct lesion on intraoperative cholangiogram. Endoscopic retrograde cholangioscopy showed an adenomatous polyp with high grade dysplasia involving the distal common bile duct. The patient underwent distal bile duct resection with choledochojejunostomy but presented with jaundice 4 years after surgery. She was found to have adenocarcinoma involving the small bowel in the Roux limb of jejunum and transverse colon. All three patients in our series presented with interval gastrointestinal

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

  18. A phantom gallbladder on endoscopic retrograde cholangiopancreatography

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Various complications have been related to laparoscopic cholecystectomy but most occur shortly after the procedure. In this report, we present a case with very late complications in which an abscess developed within the gallbladder fossa 6 years after laparoscopic cholecystectomy. The abscess resolved after treatment with CT-guided extrahepatic aspiration. However, 4 years later, an endoscopic retrograde cholangiopancreatography (ERCP) performed for choledocholithiasis demonstrated a "gallbladder" which communicated with the common bile duct via a patent cystic duct. This unique case indicates that a cystic duct stump may communicate with the gallbladder fossa many years following cholecystectomy.

    A 69-year-old white male was admitted to the hospital for right upper quadrant pain, fever, and vomiting. Acute cholecystitis was not thought to be present because of a negative ultrasonogram and oral cholecystogram. A sup(99m)Tc-PIPIDA hepatobiliary study showed definite evidence of gallbladder perforation, with pockets of radiolabeled bile in the abdomen. Immediate surgery confirmed the scan diagnosis. In patients who are at high risk for gallbladder perforation the technetium-99m-labeled iminodiacetic acid hepatobiliary scan should be considered as a first procedure to rule out acute cholecystitis and possible gallbladder perforation.

    2016-08-01

    We present rigorous upper and lower bounds on the emptiness formation probability for the ground state of a spin-1/2 Heisenberg XXZ quantum spin system. For a d-dimensional system we find a rate of decay of the order {exp(-c L^{d+1})} where L is the sidelength of the box in which we ask for the emptiness formation event to occur. In the {d=1} case this confirms previous predictions made in the integrable systems community, though our bounds do not achieve the precision predicted by Bethe ansatz calculations. On the other hand, our bounds in the case {d ≥ 2} are new. The main tools we use are reflection positivity and a rigorous path integral expansion, which is a variation on those previously introduced by Toth, Aizenman-Nachtergaele and Ueltschi.

    On the basis of oral cholecystography (OCG), we selected gallstone patients for nontoperative intervention. Their gallbladder function was considered as normal when gallbladder contracted over 50%-75% after a fat meal at 1 hour. We collected 99 gallstone patients and 19 normal controls; gallbladder function was normal in 77 patients and poor in 22. After a fat meal gallbladder volumes were calculated by B ultrasonography. The results showed that both fasting and residual volume in patients with so-called normal contraction were significantly greater than that in the controls (P OCG. PMID:7555394

    Within the whole world container traffic, the largest share of containers is in the status of repositioning. Container repositioning results from the need for harmonization between the point of empty container accumulation and the point of demand, and waiting time for the availability of the first next transport of cargo. This status of containers on the container market is the consequence of imbalances in the worldwide trade distribution on most important shipping routes. The need for fast a...

  6. Gastric emptying in morbid obesity

    International Nuclear Information System (INIS)

    Weight loss following gastroplasty had no correlation with gastric emptying rate. Patients who showed transient prolongation of gastric emptying returned to normal one year later and showed no significant difference in weight loss from those who did not have temporary delayed gastric emptying. Perhaps gatroplasty (at least temporarily) reduces the gastric volume producing early satiation without affecting the gastric emptying rate as tested by a small volume radiolabelled test meal. Longer follow-up is indicated to see if delayed weight gain occurs because of gastric pouch stretching and if this has any correlation with gastric emptying rate. (Author)

    Full Text Available Objectives: To assess the effect of periodic and moderate alcohol intake on gallbladder motility. Methods: The ultrasonographic ellipsoid method was used in 21 healthy male subjects: 12 non-alcohol and 9 alcohol drinkers. The stimulus for gallbladder contraction was 165 ml of half cream milk. Gallbladder dynamics were studied for 20 minutes following the ingestion of the milk. The mean percentage change in gallbladder volume after 10 and 20 minutes gave indications of gallbladder motility. Results: Moderate and periodic alcohol intake did not stimulate rapid postprandial gallbladder emptying. Conclusion: The protective effect of alcohol against biliary cholesterol cholelithiasis could not be due to stimulation of gallbladder emptying.

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

    International Nuclear Information System (INIS)

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

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

    Imaging of the gallbladder demonstrates a wide range of anatomical variants, including anomalies in location, number and shape. Duplication anomalies are quite rare and are characterized by a large variety of configurations depending on the size and degree of fusion of the two lobes, and on the number and disposition of the cystic ducts. We present a case of a deeply cleft, bilobed gallbladder imaged by computed tomography (CT), ultrasonography (US) and oral cholecystography (OCG). The anomaly consisted of complete duplication of the body and fundus into two distinct and separated lobes both of which entered a single infundibulum. Awareness of congenital gallbladder variants may help in recognizing and correctly classifying gallbladder abnormalities, thus preventing misdiagnoses. PMID:7719690

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

  19. Impact of cholescintigraphy and ultrasound in the management of gallbladder disease

    International Nuclear Information System (INIS)

    Major objectives of this study were to determine the functional changes that occur in chronic calculous cholecystitis (CCC) and chronic acalculous cholecystitis (CAC), and establish objective parameters of biliary pain. Total of 800 patients, who underwent serial cholecystectomy from March 1999 to May 2002 were chosen for retrospective analysis. They were divided into function and morphology groups. The function group underwent cholecystokinin cholescintigraphy and ultrasound imaging, and morphology group had only ultrasound imaging. Basal hepatic bile flow, gallbladder ejection fraction (EF), ejection period (EP), and ejection rate (ER) were measured. Functional parameters of CCC and CAC were compared with each other and also with data from 22 control subjects. Sensitivity, specificity, and accuracy, and positive predictive and negative predictive values of ultrasound for gallstone were calculated. Patients with acute or subacute cholecystitis had obstruction of the cystic duct. Bile entry into the gallbladder was normal in both CAC and CCC. Cholecystokinin administration induced cystic duct spasm causing significant reduction in EF (16±13% and 21±17%, p< 0.001) and ER (2±1%/min. and 2±1%/min., P<0.0001) in both CCC and CAC when compared to control subjects (EF of 54+17% and ER of 5.1+3.7%/min). Ultrasound overall sensitivity of 88%, accuracy of 86%, and specificity of 77% for gallstones were much lower than previously published values. It was concluded that obstruction of the cystic duct is the common feature for both acute and subacute cholecystitis. Spasm of the cystic duct on exposure to cholecystokinin causes low EF and low ER, resulting in bile stasis in both CCC and CAC. Reliance on morphology imaging alone with ultrasound may result in inappropriate gallbladder therapy either due to over diagnosis (false-positive for gallstone) or under diagnosis (false-negative in cystic duct spasm). Addition of quantitative cholescintigraphy provides objective

  20. Placement of an implantable port catheter in the biliary stent: an experimental study in dogs

    International Nuclear Information System (INIS)

    To investigate the feasibility of port catheter placement following a biliary stent placement. We employed 14 mongrel dogs as test subject and after the puncture of their gaIl bladders using sonographic guidance, a 10-mm in diameter metallic stent was placed at the common duct. In 12 dogs, a 6.3 F port catheter was placed into the duodenum through the common duct and a port was secured at the subcutaneous space following stent placement. As a control group, an 8.5 F drain tube was placed into the gallbladder without port catheter placement in the remaining two dogs. Irrigation of the bile duct was performed every week by injection of saline into the port, and the port catheter was replaced three weeks later in two dogs. Information relating to the success of the procedure, complications and the five-week follow-up cholangiographic findings were obtained. Placement of a biliary stent and a port catheter was technically successful in 13 (93%) dogs, while stent migration (n=3), gallbladder rupture (n=1) and death (n=5) due to subcutaneous abscess and peritonitis also occurred. The follow-up was achieved in eight dogs (seven dogs with a port catheter placement and one dog with a drain tube placement). Irrigation of the bile duct and port catheter replacement were successfully achieved without any complications. Cholangiograms obtained five weeks after stent placement showed diffuse biliary dilation with granulation tissue formation. However, focal biliary stricture was seen in one dog with stent placement alone. Placement of a port catheter following biliary stent placement seems to be feasible. However, further investigation is necessary to reduce the current complications

    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.

    The thickening of the gallbladder wall is a valuable finding for the diagnosis of cholecystitis, but may be seen in non-cholecystic disease as well as in acute or chronic cholecystitis. The purpose of this study is to determine the value of color Doppler sonography in differentiating the causes of thickened gallbladder wall. Ninety eight patients with thickened gallbladder wall(more than 3mm) which was not due to gallbladder cancer were prospectively evaluated with color Doppler sonography. Sixty-six cases, confirmed by pathologic reports and clinical records, were analyzed for correlation between thickened gallbladder wall and color flow signal according to the underlying causes. Of the 66 patients, 28 cases were cholecystitis and 38 cases had non-cholecystic causes such as liver cirrhosis, ascites, hepatitis, pancreatitis, renal failure, and hypoalbuminemia. Of the 28 patients with cholecystitis(12 acute, 16 chronic), 23(82%) had color Doppler flow signals in the thickened gallbladder wall. Of the 38 patients with non-cholecystic causes, eight(21%) had color Doppler flow signals. There was a statistically significant difference of color Doppler flow signals between the cholecystitis and non-cholecystic groups(p=0.0001). No significant difference of color Doppler flow signals was found between cases of acute and chronic cholecystitis. Of the 23 patients with color Doppler flow signals in 28 cases of cholecystitis, 18(78.3%) showed a linear pattern and five(21.7%) showed a spotty pattern. Of the eight patients with color Doppler flow signals in the 38 non-cholecystic cases, four(50%) showed a linear pattern and four(50%) showed a spotty pattern. In cholecystitis, a linear color Doppler flow signal pattern is a much more frequent finding than a spotty pattern. Color Doppler sonography is a useful and adequate method for determining whether a thickened gallbladder wall is the result of cholecystitis or has non-cholecystic causes.

  4. Color doppler sonography in thickened gallbladder wall

    International Nuclear Information System (INIS)

    The thickening of the gallbladder wall is a valuable finding for the diagnosis of cholecystitis, but may be seen in non-cholecystic disease as well as in acute or chronic cholecystitis. The purpose of this study is to determine the value of color Doppler sonography in differentiating the causes of thickened gallbladder wall. Ninety eight patients with thickened gallbladder wall(more than 3mm) which was not due to gallbladder cancer were prospectively evaluated with color Doppler sonography. Sixty-six cases, confirmed by pathologic reports and clinical records, were analyzed for correlation between thickened gallbladder wall and color flow signal according to the underlying causes. Of the 66 patients, 28 cases were cholecystitis and 38 cases had non-cholecystic causes such as liver cirrhosis, ascites, hepatitis, pancreatitis, renal failure, and hypoalbuminemia. Of the 28 patients with cholecystitis(12 acute, 16 chronic), 23(82%) had color Doppler flow signals in the thickened gallbladder wall. Of the 38 patients with non-cholecystic causes, eight(21%) had color Doppler flow signals. There was a statistically significant difference of color Doppler flow signals between the cholecystitis and non-cholecystic groups(p=0.0001). No significant difference of color Doppler flow signals was found between cases of acute and chronic cholecystitis.

    Full Text Available Objective: the aim of this study was to evaluate the incidence, clinical features and role of laparoscopic cholecystectomy (LC in patients with chronic acalculous cholecystitis (CAC in comparison with a control group of patients who underwent cholecystectomy for chronic calculous cholecystitis (CCC. Material and methods: prospective evaluation of 34 patients with CAC in contrast with 297 patients with CCC. Outcome measures: clinical presentation, quality of life using the Gastrointestinal Quality of Life Index (GIQLI, usefulness derived from the therapeutic procedure as measured in quality of life units by GIQLI, and clinical efficacy at one year of follow-up. Results: the incidence of complicated biliary disease was higher in CAC (27%, in comparison with CCC (13.8%. The histological study of the excised gallbladder revealed a higher incidence of cholesterolosis associated with chronic cholecystitis in the CAC group (64.9%. GIQLI showed significant differences between preoperative and postoperative measurements in both groups. The associated usefulness of LC was similar in both groups (73 versus 67.3 per cent, confirming an important increase in quality of life for both categories. Conclusions: the incidence of CAC is 11 per cent with a high association with cholesterolosis. Quality of life and LC usefulness are similar to those of patients with CCC. Due to the fact that cholecistogammagraphy is a technique not available in daily clinical practice, and that oral cholecystography and dynamic ultrasound are reliable when a positive result is obtained, extended clinical evaluation is still the most reliable indicator for cholecystectomy.Objetivo: evaluar la incidencia, manifestaciones clínicas y el papel de la colecistectomía laparoscópica (CL en pacientes con diagnóstico de colecistitis crónica alitiásica (CCA en comparación con un grupo control de pacientes intervenidos por colecistitis crónica litiásica (CCL.

    Full Text Available Context Heterotopic pancreas is a rare entity. Thirty-three cases in the gallbladder have been reported. We describe the first case of heterotopic pancreas mimicking a gallbladder cancer, identified within a calcified lesion in the thickened posterior wall of the gallbladder. Case report A 72-year-old woman with right upper quadrant pain was referred with a suspicion of gallbladder neoplasia. A CT scan demonstrated a 1 cm thickened posterior wall of the gallbladder with a 2 mm punctate calcification. An open cholecystectomy was carried out without complication. The frozen section demonstrated pancreatic tissue. Conclusion Heterotopic pancreas of the gallbladder is highly uncommon. It can mimic a neoplastic process in the gallbladder, particularly in the context of calcification. Its malignant potential in the gallbladder is unknown, in contrast to previously described neoplastic transformation with gastric heterotopic pancreas.

    International Nuclear Information System (INIS)

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

  12. Endoscopic ultrasound-guided biliary drainage of hilar biliary obstruction.

    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.

    Biliary tract carcinomas (BTC) are a group of tumours arising from the epithelial cells of intra- and extra-hepatic biliaryducts and the gallbladder, characterised by a poor prognosis. Surgery is the only curative procedure, but the risk of recurrence is high and furthermore, the majority of patients present with unresectable disease at the time of diagnosis. Systemic therapy is the mainstay of treatment for patients who present recurrent or metastatic disease. Progress has been made in the last decade to identify the most effective chemotherapy regimens, with the recent recommendation of the combination of gemcitabine-cisplatin as the standard schedule. Comprehension of the molecular basis of cholangiocarcinogenesis and tumour progression has recently led to the experimentation of targeted therapies in patients with BTC, demonstrating promising results. In this review we will discuss the clinical experience with systemic treatment for BTC, focusing on future directions with targeted therapies. PMID:22809696

    International Nuclear Information System (INIS)

    Aims: To evaluate clinical outcomes in patients with typical biliary pain, normal ultrasonic findings, and a positive 99mtechnetium (Tc)-labelled hepatic iminodiacetic acid analogue (HIDA) scintigraphy with cholecystokinin (CCK) provocation indicating gallbladder dyskinesia, as per Rome III criteria, undergoing laparoscopic cholecystectomy (LC). Methods and materials: Consecutive patients undergoing LC for gallbladder dyskinesia were identified retrospectively. They were followed up by telephone interview and review of the electronic case records to assess symptom resolution. Results: One hundred consecutive patients (median age 44; 80% female) with abnormal gallbladder ejection fraction (GB-EF <35%) were followed up for a median of 12 months (range 2–80 months). Following LC, 84% reported symptomatic improvement and 52% had no residual pain. Twelve percent had persisting preoperative-type pain of either unchanged or worsening severity. Neither pathological features of chronic cholecystitis (87% of 92 incidences when histology available) nor reproduction of pain on CCK injection were significantly predictive of symptom outcome or pain relief post-LC. Conclusion: In one of the largest outcome series of gallbladder dyskinesia patients in the UK with a positive provocation HIDA scintigraphy examination and LC, the present study shows that the test is a useful functional diagnostic tool in the management of patients with typical biliary pain and normal ultrasound, with favourable outcomes following surgery. - Highlights: • Gallbladder dyskinesia (GD) is a challenging condition to diagnose and treat. • This study evaluated clinical outcomes following laparoscopic cholecystectomy (LC). • There was sustained symptomatic benefit in >80% following surgery. • Pre-operative counselling before LC is important

  5. Arachidonate metabolism in bovine gallbladder muscle

    International Nuclear Information System (INIS)

    Incubation of (1-14C]arachidonic acid (AA) with homogenates of bovine gallbladder muscle generated a large amount of radioactive material having the chromatographic mobility of 6-keto-PGF1 alpha (stable product of PGI2) and smaller amounts of products that comigrated with PGF2 alpha PGE2. Formation of these products was inhibited by the cyclooxygenase inhibitor indomethacin. The major radioactive product identified by thin-layer chromatographic mobility and by gas chromatography - mass spectrometric analysis was found to be 6-keto-PGF1 alpha. The quantitative metabolic pattern of [1-14C]PGH2 was virtually identical to that of [1-14C]AA. Incubation of arachidonic acid with slices of bovine gallbladder muscle released labile anti-aggregatory material in the medium, which was inhibited by aspirin or 15-hydroperoxy-AA. These results indicate that bovine gallbladder muscle has a considerable enzymatic capacity to produce PGI2 from arachidonic acid

    Congenital absence of the common bile duct (CBD) is an extremely rare developmental anomaly with right and left hepatic ducts draining directly into the gallbladder (GB). Other synonyms for this clinical condition are "cholecystohepatic ducts", "transverse lie of the GB" or "interposition of the GB". The potential for iatrogenic injury is high, because of either inadvertent division or ligation of the ducts. Diagnosis is mostly made intraoperatively, and needs some form of biliary reconstruction. Herein, we are reporting a case of congenital absence of the CBD in a 36-year-old lady that was detected intraoperatively. PMID:27279403

    Agenesis of the gallbladder, a rare anomaly, is generally regarded as an organogenic failure. Several reports suggest that this congenital defect is inherited but that supposition remains controversial. We described agenesis of the gallbladder in identical twins. A 21-year-old female presented with a history of acute pain in the epigastrium and right hypochondrium. Various imaging modalities showed "gallbladder agenesis." Moreover, her older identical twin sister had also no visualized gallbladder in imaging modalities. This case report strongly suggested that agenesis of the gallbladder would be caused by a genetic abnormality. PMID:26925274

    Various pathologies involving the gallbladder can manifest clinically, producing nonspecific clinical symptoms and making diagnosis difficult and challenging. Real-time sonography is the most widely used diagnostic study for the gallbladder and the primary screening examination of choice. With increasing use of magnetic resonance imaging (MRI) and MR cholangiopancreatography (MRCP), gallbladder pathology is frequently seen. Understanding the basic patterns of various disease manifestations and appearance on MRI is the key to making an accurate diagnosis. Given its inherent tissue contrast and contrast sensitivity, MRI in conjunction with MRCP can be a very valuable test in evaluating gallbladder pathology. Gallbladder pathology can be classified into congenital (such as absence), inflammatory (acute, hemorrhagic, and chronic cholecystitis), traumatic, benign (polyps) and malignant tumors (gallbladder carcinoma and lymphoma), and other disease processes can be seen in cholelithiasis, cholesterosis, thickened gallbladder wall, and Mirrizzi syndrome.

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.

    Isolated mycobacterial infection of gall bladder is an extremely rare entity. Only anecdotal reports are evident in the literature. A preoperative diagnosis of mycobacterial infection of gallbladder is therefore very difficult. The case of a 72-year-old male who underwent surgery for suspected gallbladder cancer is presented. The diagnosis of cancer was based on radiological findings and an abnormal uptake of fluorine-18-fluoro-2-deoxy-D-glucose (FDG) on positron emission tomography (PET) sca...

  1. Radiation therapy for patients with obstructive jaundice caused by carcinoma of the extrahepatic biliary system

    International Nuclear Information System (INIS)

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

  3. Clinical usefulness of FDG-PET for biliary cancer

    International Nuclear Information System (INIS)

    Forty-one patients with biliary cancer (22 extrahepatic bile duct cancer, 11 gall bladder cancer, 8 ampullary cancer) who underwent 18F-fluorodeoxy-glucose positron emission tomography (FDG-PET) before treatment were enrolled in the present study. We investigated the clinical significance of PET for primary tumor, metastases and the other cancers. We also analyzed the relationship between the maximum standardized uptake value (SUVmax) and clinicopathologic factors. The accumulation of FDG to primary tumor was observed in 28 of 41 patients (68.3%). The sensitivity of FDG-PET was 100% for gallbladder cancer, 87.5% for ampullary cancer, and 45.4% for bile duct cancer, respectively. The SUVmax levels in primary tumor were significantly correlated with M-category in tumor, nodes and metastasis (TNM) classification (p=0.033). Meanwhile, 21 patients (51%) showed the FDG accumulation except for the primary tumor. The sensitivity for lymph node metastasis, liver metastasis, and peritoneal dissemination was 89%, 75%, and 100%, respectively. In the abnormal accumulations of the other regions in 8 patients, colon cancer was newly found in 3 patients. FDG-PET has a low sensitivity for detecting the primary tumor in biliary cancer, but it is useful for detection of distant metastasis and occult malignant disease. (author)

    2010-01-01

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

    Biliary bacteria have been implicated in gallstone pathogenesis, though a clear understanding of their composition and source is lacking. Moreover, the effects of the biliary environment, which is known to be generally hostile to most bacteria, on biliary bacteria are unclear. Here, we investigated the bacterial communities of the biliary tract, duodenum, stomach, and oral cavity from six gallstone patients by using 16S rRNA amplicon sequencing. We found that all observed biliary bacteria wer...

    We report a rare case of a 74-year-old man with metachronous gallbladder cancer and bile duct cancer who underwent curative resection twice, with the operations nine years apart. At the age of 65 years,the patient underwent a cholecystectomy and resection of the liver bed for gallbladder cancer. This was a welldifferentiated adenocarcinoma, with negative resection margins (T2N0M0, stage ⅠB). Nine years later,during a follow-up examination, abdominal computed tomography and MRCP showed an enhanced 1.7 cm mass in the hilum that extended to the second branch of the right intrahepatic bile duct. We diagnosed this lesion as a perihilar bile duct cancer, Bismuth type Ⅲ a, and performed bile duct excision, right hepatic lobectomy and Roux-en-Y hepaticojejunostomy.The histological diagnosis was a well-differentiated adenocarcinoma with one regional lymph node metastasis (T1N1M0, stage ⅡB). Twelve months after the second operation, the patient is well, with no signs of recurrence. This case is compared with 11 other cases of metachronous biliary tract cancer published in the world medical literature.

    To determine whether an analysis of two-phase CT features provides a sound basis for differential diagnosis between gallbladder carcinoma and cholecystitis. We reviewed a total of 89 cases of gallbladder carcinoma (n=35) or cholecystitis (n=54) in patients who had undergone two-phase spiral CT. For this, a GE Highspeed Advantage scanner (GE Medical Systems, Milwaukee, U . S . A .) was used. A total of 120ml of contrast material was injected at a rate of 2-3 ml/sec. Arterial and venous phase scans were obtained 35 and 65 seconds, respectively, after the initiation of contrast infusion. All cases of gallbladder carcinoma and 468 of cholecystitis (of a total of 482) were confirmed by histopathology. We reviewed the two phase spiral CT features, analyzing and assessing thickness of the lesion, the enhancement pattern seen during the arterial and the venous phase, invasion of liver, pericholecystic fat infiltration, dilatation of intrahepatic ducts, and other associated findings. Mean wall thickness was 12.6 mm in the gallbladder carcinoma group, and 7.2 mm in the cholecystitis group. The common enhancement patterns seen in gallbladder carcinoma were 1) a highly enhanced thick inner wall layer during the arterial phase which became iso attenuated with adjacent liver parenchyma during the venous phase (16/35; 45.7%) and 2) highly enhanced thick inner wall layer during both the arterial and venous phase (8/35; 22.9%). The most common enhancement pattern in cholecystitis cases was an iso attenuated thin inner wall layer during both the arterial and the venous phase (44/54; 81.5%). Findings of intrahepatic mass formation by direct invasion (9/35), lymph node enlargement (12/35), and metastasis to other organs (7/35) occurred only in cases of gallbladder carcinoma (18/35, 51.4%) than of cholecystitis (10/54, 18.5%). The incidence of pericholecystic fat infiltration and fluid collection was not significantly different between the gallbladder cancer and cholecystitis groups

    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.

    Background/Aims Gallstone pathogenesis is linked to mucin hypersecretion and bacterial infection. Several mucin genes have been identified in gallbladder epithelial cells (GBECs). We investigated MUC expression in cholesterol-associated gallbladder disease and evaluated the relationship between mucin and bacterial infection. Methods The present study involved 20 patients with cholesterol stones with cholecystitis, five with cholesterol stones with cholesterolosis, six with cholesterol polyps, two with gallbladder cancer, and six controls. Canine GBECs treated with lipopolysaccharide were also studied. MUC3, MUC5AC, MUC5B, and MUC6 antibodies were used for dot/slot immunoblotting and immunohistochemical studies of the gallbladder epithelial tissues, canine GBECs, and bile. Reverse-transcription polymerase chain reaction was performed to evaluate MUC3 and MUC5B expression. Results MUC3, MUC5AC, MUC5B, and MUC6 were expressed in the normal gallbladder epithelium, and of those, MUC3 and MUC5B exhibited the highest expression levels. Greatly increased levels of MUC3 and MUC5B expression were observed in the cholesterol stone group, and slightly increased levels were observed in the cholesterol polyp group; MUC3 and MUC5B mRNA was also upregulated in those groups. Canine GBECs treated with lipopolysaccharide also showed upregulation of MUC3 and MUC5B. Conclusions The mucin genes with the highest expression levels in gallbladder tissue in cholesterol-associated diseases were MUC3 and MUC5B. Cholesterol stones and gallbladder infections were associated with increased MUC3 and MUC5B expression. PMID:27563024

    Echogenic luminal contents are often noted during ultrasonographic examination of the gallbladder (GB) in canine patients, but the significance of biliary sludge is not well understood. GB contents were evaluated during 200 sequential ultrasonographic scans performed at a veterinary school, and sludge was quantified using a 1-5 scale. GB volume was retrospectively estimated from stored images. Medical records were used to determine patient demographics, clinicopathologic findings, and diagnoses/disorders. The majority of dogs (66.5%) had some hyperechoic material within the GB. Four dogs were diagnosed with a mucocele. For statistical purposes, dogs with uniformly nonechogenic bile or minimal sludge (80.5%) were compared to those with >25% sludge (17.5%). Dogs with >25% sludge were significantly older than those with minimal sludge (8 versus 11 yr). Serum cholesterol and bilirubin concentrations and activities of both alkaline phosphatase and gamma-glutamyl transferase were not correlated with the presence of GB sludge. Dogs with spontaneous hyperadrenocorticism or hypothyroidism were more likely to have >25% sludge (odds ratio: 5.04). In addition, >25% sludge was associated with increased GB volume, suggesting that changes in GB function or contractility may impact the formation of biliary sludge in dogs. PMID:27008319

  15. Primary biliary cirrhosis.

    Nguyen, Douglas L; Juran, Brian D; Lazaridis, Konstantinos N

    2010-10-01

    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.

    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.)

    Gallbladder wall thickening (3 mm or greater) is a nonspecific finding with many causes. We describe two cases caused by infectious mononucleosis. Other causes of gallbladder wall thickening are described and the literature is reviewed. We suggest that the finding of gallbladder wall thickening in a patient with infectious mononucleosis implies that the patient is very ill, and its observation should lead to close patient monitoring.

    BACKGROUND:Gallbladder adenoma is a pre-cancerous neoplasm and needs surgical resection. It is dififcult to differ-entiate adenoma from other gallbladder polyps using imaging examinations. The study aimed to illustrate characteristics of contrast-enhanced ultrasound (CEUS) and its diagnostic value in gallbladder adenoma. METHODS:Thirty-seven patients with 39 gallbladder adenoma-toid lesions (maximal diameter≥10 mm and without metastasis) were enrolled in this study. Lesion appearances in conventional ultrasound and CEUS were documented. The imaging features were compared individually among gallbladder cholesterol polyp, gallbladder adenoma and malignant lesion. RESULTS:Adenoma lesions showed iso-echogenicity in ul-trasound, and an eccentric enhancement pattern, "fast-in and synchronous-out" contrast enhancement pattern and homo-geneous at peak-time enhancement in CEUS. The homogenic-ity at peak-time enhancement showed the highest diagnostic ability in differentiating gallbladder adenoma from cholesterol polyps. The sensitivity, speciifcity, positive predictive value, negative predictive value, accuracy and Youden index were 100%, 90.9%, 92.9%, 100%, 95.8% and 0.91, respectively. The characteristic of continuous gallbladder wall shown by CEUS had the highest diagnostic ability in differentiating adenoma from malignant lesion (100%, 86.7%, 86.7%, 100%, 92.9% and 0.87, respectively). The characteristic of the eccentric enhance-ment pattern had the highest diagnostic ability in differenti-ating adenoma from cholesterol polyp and malignant lesion, with corresponding indices of 69.2%, 88.5%, 75.0%, 85.2%, 82.1% and 0.58, respectively. CONCLUSIONS:CEUS is valuable in differentiating gallbladder adenoma from other gallbladder polyps (≥10 mm in diameter). Homogeneous echogenicity on peak-time enhancement, a con-tinuous gallbladder wall, and the eccentric enhancement pat-tern are important indicators of gallbladder adenoma on CEUS.

    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.

    Ultrasonography is the technique of choice in diagnosing gallbladder calculi. In the mid-1970s ultrasound was only accurate enough to use as an adjunct to oral cholecystography but refinements such as gray scale and real-time imaging mean that in experienced hands it has a sensitivity of 96% and a specificity of 93%. Sonography is also the test of choice in the initial evaluation of jaundiced patients. It is an excellent technique for distinguishing between obstructive and nonobstructive jaun...

    The anatomy facing a surgeon during cholecystectomy is challenging as it involves complex relationship between the gallbladder, hepatic artery and extra-hepatic billiary tree. We report a case of septate gall bladder which was successfully treated with laparoscopic cholecystectomy. In this paper, we also discuss the embryology and characteristics of this rare anomaly. Lack of awareness, non-specific symptoms, signs and inadequacy of imaging methods are possible reasons for the reported proble...

    Extraskeletal osteosarcoma is a rare malignant soft tissue tumour. At open cholecystectomy performed for gallstones, a 61-year-old woman was found to have osseous tissue in the wall of the gallbladder. Histopathological examination of the specimen revealed a focus of extraskeletal osteosarcoma. The patient developed widespread intra-abdominal metastases 5 months after the operation, and died of pulmonary deposits at 9 months. Although osteosarcoma has rarely been reported at other extraskelet...

    AIM: To study the behavior as well as optimal treatment of gallbladder sarcomatoid carcinoma, we reviewed the results of treatment of gallbladder sarcomatoid carcinoma from Chang Gung Memorial Hospital. METHODS: From 1987 to 2005, six patients were diagnosed with gallbladder sarcomatoid carcinoma and treated at our institution. Tumor staging was based on 2002 revised tumor-node-metastasis (TNM) staging for gall bladder cancer from the American Joint Committee on Cancer. The clinical presentation, laboratory data and preoperat ive workup were reviewed retrospectively. RESULTS: Five patients were female and one was male. The age ranged from 51 to 66 years (median, 58 years). Surgical procedures included three curative resections, two palliative resections and one biopsy. There were two surgical complications (33.3%) and one case of surgical mortality (16.7%). The followup time ranged from 30 d to 5 mo. The median survival was 2.5 mo. The prognosis was extremely poor, even after curative resection and postoperative chemotherapy. CONCLUSION: The prognos i s of gal lbladder sarcomatoid carcinoma was not dependent on TNM stage and was always dismal. The clinicopathological features were different from those of gall bladder cancer.

  12. 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.

  17. Complete response in gallbladder cancer to erlotinib plus gemcitabine does not require mutation of the epidermal growth factor receptor gene: a case report

    International Nuclear Information System (INIS)

    Gallbladder cancer typically follows an aggressive course, with chemotherapy the standard of care for advanced disease; complete remissions are rarely encountered. The epidermal growth factor receptor (EGFR) is a promising therapeutic target but the activity of single agent oral EGFR tyrosine kinase inhibitors is low. There have been no previous reports of chemotherapy plus an EGFR-tyrosine kinase inhibitor (TKI) to treat gallbladder cancer or correlations of response with the mutation status of the tyrosine kinase domain of the EGFR gene. A 67 year old man with metastatic gallbladder cancer involving the liver and abdominal lymph nodes was treated with gemcitabine (1000 mg/m2) on day 1 and 8 every 21 days as well as daily erlotinib (100 mg). After four cycles of therapy, the CA 19-9 normalized and a PET/CT showed a complete remission; this response was maintained by the end of 12 cycles of therapy. Gemcitabine was then discontinued and single agent erlotinib was continued as maintenance therapy. The disease remains in good control 18 months after initiation of therapy, including 6 months on maintenance erlotinib. The only grade 3 toxicity was a typical EGFR-related skin rash. Because of the remarkable response to erlotinib plus gemcitabine, we performed tumor genotyping of the EGFR gene for response predicting mutations in exons 18, 19 and 21. This disclosed the wild-type genotype with no mutations found. This case report demonstrates a patient with stage IV gallbladder cancer who experienced a rarely encountered complete, prolonged response after treatment with an oral EGFR-TKI plus chemotherapy. This response occurred in the absence of an EGFR gene mutation. These observations should inform the design of clinical trials using EGFR-TKIs to treat gallbladder and other biliary tract cancers; such trials should not select patients based on EGFR mutation status

    2009-05-01

    Full Text Available Abstract A cyclosporine (CsA-based immunosuppression is associated with an increased incidence of cholelithiasis after heart transplantation. It is not known if tacrolimus (Tac has comparable biliary side effects in humans. We evaluated the incidence of gallbladder sludge and cholelithiasis under Tac-based immunosuppression by ultrasound examinations in 31 cardiac transplants (25 male, 6 female, mean age: 59 ± 11 years. Data were compared to 57 patients (47 male, 10 female, mean age: 58 ± 11 years who received CsA-based immunosuppression. 6 patients receiving Tac and 6 patients receiving CsA had already gallstones prior to transplantation so that finally 25 patients of the Tac group and 51 patients of the CsA group could be evaluated. In the Tac group the incidence of biliary sludge was 4% (1 of 25, of gallstones 28% (7 of 25. In comparison, patients receiving CsA developed biliary sludge in also 4% (2 of 51 and gallstones in 25% (13 of 51. Nine of 42 males in the CsA group (21% and eight of 20 males in the Tac group (40% developed either gallstones or sludge (n.s. Six of nine females in the CsA group (67%, but none of five females in the Tac group (0% developed either gallstones or sludge (p = 0.01. In summary, the incidence of biliary disease in patients with Tac is comparable with CsA-based immunosuppression. We recommend regular sonographical examinations to detect biliary diseases as early as possible. In cases of clinically, laboratory and sonographical signs of cholecystitis cholecystectomy is indicated. It seems that towards lithogenicity female patients benefit more from a Tac-based treatment because the occurrence of gallstones is rare.

    Full Text Available A 35-year-old mother was scheduled to be the living donor for liver transplantation to her second son, who suffered from biliary atresia complicated with biliary cirrhosis at the age of 2 years. The operative plan was to recover the left lateral segment of the mother’s liver for living donor transplantation. With the use of cholangiography at the time of surgery, we found the right anterior segmental duct (RASD emptying directly into the cystic duct, and the catheter passed into the RASD. After repairing the incision in the cystic duct, transplantation was successfully performed. Her postoperative course was uneventful. Biliary anatomical variations were frequently encountered, however, this variation has very rarely been reported. If the RASD was divided, the repair would be very difficult because the duct will not dilate sufficiently in an otherwise healthy donor. Meticulous preoperative evaluation of the living donor’s biliary anatomy, especially using magnetic resonance cholangiography and careful intraoperative techniques, is important to prevent bile duct injury and avoid the risk to the healthy donor.

    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.

  1. Safety of exogenous (CCK-8) and endogenous (fatty meal) cholecystokinin (CCK) induced gallbladder (GB) dynamics in patients with cholelithiasis

    International Nuclear Information System (INIS)

    The quantitation of biliary dynamics in patients requires induction of GB contraction and emptying the CCK. However, it is not clear how safe it is to induce GB emptying in a patient with known gallstones. This study was undertaken to document the safety of induction of GB emptying in 50 patients with gallstones and the results are compared with 55 normal subjects. After 4-6 hours of fast, each subject was given 3-5 mCi of Tc-99m-IDA. Sixty minutes later, the subject was positioned under a gamma camera and the data were acquired at 1 frame/min. for 30 min. (CCK-8) or 60 minutes (fatty meal). Saline placebo was given at 5 minutes and CCK-8 or fatty meal at 10 minutes. Onset of symptoms was recorded and correlated with GB ejection period. GB ejection fraction (EF) was calculated for 3 doses (5, 10 and 40 ng/kg) of CCK-8 and fatty meal (8 oz/70 kg). Compared to normals, GB emptying in general was lower in patients with cholelithiasis for all 3 doses of CCK-8 and fatty meal. Five patients (10%) with choleithiasis experienced a mild to moderate degree of nausea and intermittent abdominal pain during GB ejection and the symptoms were similar to their previous experience during an attack of cholecystitis. All symptoms abated within 10 minutes without therapy. No incidence of impaction of GB stone in the common bile duct was seen. It is concluded that the GB emptying required for quantitative biliary dynamics can be induced safely with either exogenous or endongenous CCK in patients with known cholelithiasis

    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.

    2010-01-01

    Full Text Available INTRODUCTION: Gallbladder cancer, which is characterized by rapid progression and a poor prognosis, is a complex disease to treat. Unfortunately, little is known currently about its etiology or pathogenesis. A better understanding of its carcinogenesis and determining risk factors that lead to its development could help improve the available treatment options. METHOD: Based on this better understanding, the histological alterations (such as acute cholecystitis, adenomyomatosis, xanthogranulomatous cholecystitis, polyps, pyloric metaplasia, intestinal metaplasia, dysplasia, cancer and others in gallbladders from 1,689 patients who underwent laparoscopic cholecystectomy for cholecystolithiasis were analyzed. The association of these gallbladder histological alterations with clinical data was studied. RESULTS: Gender analysis revealed a greater incidence of inflammatory changes in males, while dysplasia and cancer were only found in women. The incidence of cholesterolosis was greater in the patients 60 years of age and under, and the incidence of adenomyomatosis and gangrene was greater in the elderly patients. A progressive increase in the average age was observed as alterations progressed through pyloric metaplasia, intestinal metaplasia, dysplasia and then cancer, suggesting that the metaplasia-dysplasia-carcinoma sequence may occur in gallbladder cancer. Gallbladder histological alterations were also observed in asymptomatic patients. CONCLUSION: The results of this study suggest that there could be an association between some histological alterations of gallbladder and cancer, and they also suggest that the metaplasia-dysplasia-carcinoma sequence could in fact be true in the case of gallbladder cancer. Nevertheless, further studies directed towards a perfect understanding of gallbladder carcinogenesis are required.

    There are currently no reports of identification of stem cells in human gallbladder. The differences between human gallbladder and intrahepatic bile duct (IHBD) cells have also not been explored. The goals of this study were to evaluate if human fetal gallbladder contains a candidate stem cell population and if fetal gallbladder cells are distinct from fetal IHBD cells. We found that EpCAM+CD44+CD13+ cells represent the cell population most enriched for clonal self-renewal from primary gallbladder. Primary EpCAM+CD44+CD13+ cells gave rise to EpCAM+CD44+CD13+ and EpCAM+CD44+CD13- cells in vitro, and gallbladder cells expanded in vitro exhibited short-term engraftment in vivo. Last, we found that CD13, CD227, CD66, CD26 and CD49b were differentially expressed between gallbladder and IHBD cells cultured in vitro indicating clear phenotypic differences between the two cell populations. Microarray analyses of expanded cultures confirmed that both cell types have unique transcriptional profiles with predicted functional differences in lipid, carbohydrate, nucleic acid and drug metabolism. In conclusion, we have isolated a distinct clonogenic population of epithelial cells from primary human fetal gallbladder with stem cell characteristics and found it to be unique compared to IHBD cells.

    A retrospective analysis was performed of case histories and of results of sonographic investigations in liquidators of the Chernobyl accident suffering from chronic abnormalities of the biliary ducts. Patients with cholecystitis were studied for the biochemical composition of their bile. The incidence of the gallbladder disorders (chronic cholecystitis, angiocholitis, dyskinesias of the biliary ducts) has not changed much over the last 10 years having elapsed since the accident. The biochemical composition of bile was found to have been changed to a greater extent in the liquidators of the Chernobyl accident than it was in those having avoided danger of exposure to ionizing radiation. Mechanisms of origination of cholelithiasis are discussed on the basis of investigations designed to study biochemical properties of bile and findings secured with the aid of the ultrasound techniques.

  10. Percutaneous Cholangioscopy in the Management of Biliary Disease: Experience in 25 Patients

    International Nuclear Information System (INIS)

    Purpose: To present our experience performing percutaneous cholangioscopy in the management of 25 patients with biliary disease.Methods: During the last 3 years, 26 percutaneous cholangioscopies were performed in 25 patients with common bile duct disease (n = 16), intrahepatic ducts disease (n = 6), and gallbladder disease (n = 4). Our patient population group included seven with common bile duct stones, three with intrahepatic lithiasis, and eight with benign strictures (six iatrogenic and two postinflammatory). In four patients malignancy was to be excluded, in two the tumor extent was to be evaluated, whereas in one case the correct placement of a metallic stent needed to be controlled. A 9.9 Fr flexible endoscope URF-P (Olympus, 1.2 mm working channel, 70-cm length) was used.Results: In total, percutaneous cholangioscopy answered 30 diagnostic questions, was technically helpful in 19 cases (performing lithotripsy or biopsy or guiding a wire), and of therapeutic help in 12 (performing stone retrieval). In 24 of 26 cases the therapeutic decision and the patient management changed because of the findings or because of the help of the method. In two cases biliary intervention failed to treat the cause of the disease. No major complication due to the use of the endoscopy was noted.Conclusions: Percutaneous cholangioscopy is a very useful tool in the management of patients with biliary disease. The method can help in diagnosis, in performing complex interventional procedures, and in making or changing therapeutic decisions

    1999-01-01

    Full Text Available The introduction and popularization of laparoscopic cholecystectomy has been accompanied with a considerable increase in perforation of gallbladder during this procedure (10%--32%, with the occurrence of intraperitoneal bile spillage and the consequent increase in the incidence of lost gallstones (0.2%--20%. Recently the complications associated with these stones have been documented in the literature. We report a rare complication occurring in an 81-year-old woman who underwent laparoscopic cholecystectomy and developed cutaneous fistula to the umbilicus and elimination of biliary stones through the urinary tract. During the cholecystectomy, the gall bladder was perforated, and bile and gallstones were spilled into the peritoneal cavity. Two months after the initial procedure there was exteriorization of fistula through the umbilicus, with intermittent elimination of biliary stones. After eleven months, acute urinary retention occurred due to biliary stones in the bladder, which were removed by cystoscopy. We conclude that efforts should be concentrated on avoiding the spillage of stones during the surgery, and that no rules exist for indicating a laparotomy simply to retrieve these lost gallstones.

  12. Polyorethaoe-covered nitinol strecker stents as primary palliative treatment of malignant biliary obstruction

    International Nuclear Information System (INIS)

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

  13. Biliary ascariasis: the value of ultrasound in the diagnosis and management

    International Nuclear Information System (INIS)

    Conventional methods of radiographic examination are often unsatisfactory for identifying worms in the biliary tract. Ultrasonography is a non-invasive, quick and safe procedure known to have diagnostic accuracy. We studied the ultrasonographic appearance of biliary ascariasis and the role of ultrasonography in diagnosis and management. In a prospective 5-year study, a sonogarphic diagnosis of biliary ascariasis was made on 46 Yemeni patients. The diagnosis was based mainly on sonographic appearences supported by clinical and laboratory results and proved by outcome of either surgical or medical management or spontaneous exit of worms. Follow-up ultrasound was performed, for all patients, to confirm the diagnosis and to monitor the management. Parasites were present in the dilated main bile duct in 23 patients, in the gallbladder in 12 patients, in the intrahepatic ducts in 6 patients, in the main pancreatic duct in 4 patients and as an intrahepatic abscess in one patient. The characteristic appearance of Ascaris lumbricoides was a single or multiple echogenic non-shadowing linear or curved strips with or without echoic tubular central lines that represent the digestive tracts of the worm. A spaghetti-like appearance was seen in 9 patients and amorphous fragments were seen in 2 patients. Sixteen patients underwent surgery, 20 patients were treated medically (including spontaneous exit of the worm in 7 patients without treatment) and in 10 patients worms were extracted by endoscopic retrograde cholangiopancreatography. Follow-up ultrasound was found to be effective in confirming the diagnosis and monitoring management. (author)

    AIM: To determine the relationship between biliary stricture and pigment gallstone formation, and the prevention of pigment gallstones with medicine.METHODS: One hundred and eighteen male guinea pigs were randomly divided into four groups: stricture group (S, n = 30) underwent partial ligation of common bile duct, and fed on regular chow; S plus medicine group (S+M, n = 27) underwent the same operation but fed on medicinal chow (0.3 g chenodeoxycholic acid, 0.5 g glucurolactone, and 0.5 g aspirin were mixed up in 1.2 kg regular chow); medicinal control group (C+M, n = 30) was free of operation, and fed on medicinal chow; and control group (C, n = 31) was free of operation and fed on regular chow. One week later, laparotomy was performed, and the bile of gallbladder was collected, measured, and cultured.RESULTS: Gallstones were identified. Pigment gallstones were induced by biliary stricture in 95% (22/23) of S group. In the S+M group, the incidence of gallstone was reduced to 55% (11/20, vs S group, P<0.01). The changes of indirect bilirubin and ionized calcium in the bile were consistent with gallstone incidences.CONCLUSION: Biliary stricture can cause pigment gallstone formation in guinea pigs, and the medicines used can lower the incidence of gallstones. The bilirubin and ionized calcium play important roles in pigment gallstone formation.

  15. Treatment of malignant biliary occlusion by means of transhepatic percutaneous biliary drainage with insertion of metal stents - results of an 8-year follow-up and analysis of the prognostic parameters

    International Nuclear Information System (INIS)

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

  16. 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

    Oral cholecystography is a well established method for studying the human gallbladder and radiological non-visualization of the gallbladder has been shown to correlate highly with the presence of disease. The exact mechanism by which diseased gallbladders fail to visualize is unclear, but may be due to a failure of the gallbladder to concentrate the luminal contents. Concentration of gallbladder contents is achieved by the reabsorption of water, the driving force for which is active sodium (N...

  18. Magnetic resonance cholangiography: comparison of two- and three-dimensional sequences for assessment of malignant biliary obstruction

    International Nuclear Information System (INIS)

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

    Our objective was to assess the ability of dual-phase helical CT (DHCT) to predict resectability of carcinoma of gallbladder (CaGB). Thirty-two consecutive patients suspected of having CaGB on clinical examination and sonography presented to our centre over 10-month period. All these 32 patients underwent DHCT. Fifteen patients were considered inoperable and 2 had xanthogranulomatous cholecystitis. The remaining 15 patients (10 women, 5 men; age range 33-72 years) underwent surgery and had histopathological confirmation of CaGB and were included in the study based on the following criteria: presence of mass in gallbladder fossa on sonography and DHCT, and confirmation at surgery and histopathological examination. Axial reconstructions of 2 mm were obtained (collimation 3 mm, table speed 4.5 mm/s) for arterial (scan delay 20 s) and venous (scan delay 60 s) phases on a helical scanner. The criteria used for unresectability were: distant metastasis (liver, peritoneum, lymph nodes), extensive local contiguous organ spread, involvement of secondary biliary confluence of both lobes of liver, tumoral invasion of main portal vein, or proper hepatic artery or simultaneous invasion of one side hepatic artery and the other side portal vein. The CT findings related to unresectability were correlated with surgical findings. On the basis of CT findings, 10 patients were unresectable and 5 were resectable. Of the 10 patients considered unresectable, 9 had tumours that were unresectable at surgery (sensitivity 100%, positive predictive value 90%). Five patients had more than one reason and 4 had one reason alone for being unresectable (lymph nodes, n=2; hepatic metastasis, n=1; and vascular invasion, n=1). All 5 patients considered resectable based on CT findings had resectable tumours at surgery (negative predictive value 100%). The overall accuracy of CT was 93.3%. Dual-phase helical CT comprehensively evaluates CaGB and may be a useful tool in preoperative staging of this

    Objective Endoscopic gallbladder stenting (EGBS) is an alternative treatment option for high-risk surgical patients with acute cholecystitis. However, there are no reports focusing on EGBS in patients with concomitant unresectable cancer. The aim of this study was thus to evaluate EGBS in such patients. Methods Twenty-two consecutive patients with acute cholecystitis and unresectable cancer were enrolled between September 2010 and December 2014. Their median age was 74.5 years (range: 51-95). Thirteen patients were men and nine were women. The primary cancers of the patients were biliary tract cancer (9), pancreas cancer (9), lung cancer (2), gastric cancer (1), and colon cancer (1). The causes of cholecystitis were calculus cholecystitis (7), obstruction by malignant tumor (13), and obstruction by fully covered stent (2). Results EGBS was successfully performed in 17 patients (77.2%). The technical success rates for calculus cholecystitis, obstruction by malignant tumor, and obstruction by fully covered stent were 85.7% (6/7), 69.2% (9/13), and 100% (2/2), respectively. No complications were observed. Percutaneous transhepatic gallbladder drainage was conducted on two patients in whom EGBS had failed and then we performed EGBS by a rendezvous approach. Of the 19 patients in whom we finally deployed EGBS, the median follow-up period was 229 days (range: 14-880 days). A recurrence of acute cholecystitis occurred in three (15.7%) patients 14, 130, and 440 days after EGBS placement. The rates of recurrence of cholecystitis at one and two years were 10.5% and 18.7%, respectively. Conclusion Our study demonstrated that EGBS is a safe and effective method for acute cholecystitis in patients with concomitant unresectable cancer. PMID:27250045

    Full Text Available Context: Gallbladder represent the most common cancer among biliary tree, complete surgery offers only chance of cure, but most of patients with unresectable or metastatic stage, in such patients only palliative treatment be given. Aims: The aim of this retrospective study is to evaluate efficacy of chemotherapy with gemcitabine and oxaliplatin (GEMOX, and or with radiotherapy over best supportive care (BSC in unresectable gallbladder cancer (GBC. Materials and Methods: Patients with unresectable GBC were evaluated from our center between 2008 and 2011. Three cohorts were identified. Group A, BSC, Group B chemotherapy with GEMOX two weekly for maximum of six cycles. Group C, Chemotherapy with GEMOX and Radiotherapy. Patients underwent percutaneous transhepatic biliary drainage (PTBD or Endoscopic retrograde cholangiopancreatography (ERCP when required. Results: Total 50 patients included in analysis. 19 are male and 31 are female. 14 patients in Group A. 18 patients in Group B and 18 in Group C. Median follow up was 8.8 month. The progression free survival (PFS of patients who received of BSC at 15 month was 18%. PFS of patients who received chemotherapy (CCT at 28 month was 30%. PFS of patients who received CCT Chemotherapy and radiotherapy PFS at 15 month was 38%. When compared all three group none is statically significant (P = 0.538. Conclusion: Judicious used of BSC along with chemotherapy and or with radiotherapy may help in increase in period of stable disease along with overall survival (OS in selected group. In our retrospective analysis CCT with GEMOX and with radiotherapy has helped in improving the OS and PFS in few patients who had good performance status.

    AIM: Tt is difficult to differentiate gallstone dyspepsia and functional dyspepsia by clinical symptoms and signs. We hypothesized that gallstone dyspepsia was related to abnormal gallbladder motility. We aimed to differentiate gallstone dyspepsia from functional dyspepsia by measuring gallbladder motility.METHODS: We measured gallbladder volume changes in response to gastric distension (saline 500 mL) and fatty meal in 10 normal volunteers (controls) and 62 patients with gallstones and dyspepsia before cholecystectomy. Forty cholecystectomized patients were symptom free or had improvement (group I), while the remaining 22 patients had persistent dyspepsia (group II). Gallbladder volume change and ejection fraction were analyzed and compared among the three groups.RESULTS: In group I, there were significant decreases in gallbladder volumes 5-25 min after gastric distension,compared to fasting volumes. Compared to normal volunteers and group II, group I had significantly decreased gallbladder volumes 10-20 min after drinking 500 mL of normal saline and 10 to 50 min after eating fatty meal.CONCLUSION: Our results support the hypothesis that increased gallbladder contraction after gastric distension or fatty meal may be related to dyspeptic symptoms in uncomplicated gallstone disease. These findings may be useful in differentiating functional dyspepsia from gallstone dyspepsia, patients with the latter disease may benefit from laparoscopic cholecystectomy.

    Cholecystectomy is associated with an increased risk of colorectal cancer, but little is known about the relationship between gallbladder disease and colorectal adenoma. Gallbladder polyps and colorectal neoplasia (CRN) share several risk factors such as obesity, diabetes and metabolic syndrome, which might account for their association. In this study, we investigated whether asymptomatic patients with gallbladder disease are at increased risk of CRN and identified the factors to their association. The study population consisted of 4,626 consecutive, asymptomatic individuals drawn from a prospective health check-up cohort who underwent both ultrasonography and colonoscopy screening. The prevalence of CRNs in patients with gallbladder polyps or gallstones was significantly higher than that in the control group (32.1% vs. 26.8%; P = 0.032, 35.8% vs. 26.9%; P = 0.020). A multivariate regression analysis showed that gallbladder polyps were an independent risk factor for CRN [adjusted odds ratio (OR): 1.29; 95% confidence interval (CI); 1.03-1.62] whereas gallstones were not (adjusted OR: 1.14; 95% CI: 0.79-1.63). The adjusted OR for the risk of CRN was 1.12 for gallbladder polyps CRN increased with increasing polyp size (P trend = 0.022). Our results suggest that colorectal neoplasia is significantly related to gallbladder polyps, especially those ≥ 5 mm. PMID:26339169

    To study the magnetic resonance imaging (MRI) appearance of the fetal gallbladder with special reference to fetal gallbladder sludge. In a retrospective study of 512 fetuses without gastrointestinal abnormalities, we classified the gallbladder MR appearances into patterns based on the signal intensity (SI) of bile on T1-weighted and T2-weighted sequences. We analysed the ratio of T1-weighted SI of bile. Maximum gallbladder width was correlated with gestational weeks (GW) using non-linear regression analysis and compared between various imaging patterns with one-way ANOVA. Five age-dependent patterns of the MRI appearance were found: (1) SI of bile was T2-weighted hyperintense and T1-weighted hypointense (78.5%); (2) presented with T2-weighted hyperintensity and T1-weighted signal isointense to liver (10.4%); (3) moderate hyperintense T2-weighted SI, T1-weighted SI hyperintense to liver (4.9%); (4) SI was T2-weighted isointense and T1-weighted hyperintense to liver (3.7%); (5) pronounced T2-weighted hypointensity and marked T1-weighted hyperintensity (2.5%). Pattern 1 was exclusively found before 27 GW, while patterns 2-5 increased in frequency after 30 GW. The MRI appearance of the fetal gallbladder is variable; fetal bile shows age-dependent SI changes that may cause non-visualisation of the gallbladder. This may be due to sludge and/or accumulation of paramagnetic substances suspended within gallbladder mucus. (orig.)

    Full Text Available Aim. The aim of the study was to determine the ultrasonic gallbladder wall thickness in normal adult Nigerians so as to create standards for defining gallbladder abnormalities in Nigerians. Method. Four hundred adults comprising 228 (57% women and 172 (43% men aged 16 - 78 years, who had normal clinical history and physical findings, were recruited. The gallbladder wall thickness was obtained in the supine, prone and right anterior oblique positions. Differences in gallbladder wall thickness were determined using the chi-square test, while the relationship between the ultrasound-measured gallbladder wall thickness and the subjects’ age, sex, height and weight were analysed using the Pearson product moment correlation. Normal ranges and related statistics were estimated and tabulated according to age group and sex. Results. The mean age of the subjects was 32±13.2 years. The mean gallbladder wall thickness range was 1.8 - 2.8 mm±0.5mm. The thickness range for females was 1.7 - 2.7 mm±0.5 mm, and that for males was 1.9 - 2.9 mm±0.5 mm. There was a statistically significant difference (p<0.05 in the mean wall thickness between males and females. The mean body parameters (height, weight of males were significantly greater than those of females (p<0.047, p<0.000 respectively. There was no correlation between gallbladder wall thickness and age and height of subjects (r=0.34, p<0.09. Conclusion. Our study was able to establish population-specific ultrasonic values for gallbladder wall thickness in normal adults that can be reliably used as standard to define gallbladder abnormalities in Nigerians.

    We present a case of a 59-y-old woman who had undergone cholecystectomy and was subsequently found to have an abscess within the gallbladder fossa. A hepatobiliary scan using (99m)Tc-diisopropyliminodiacetic acid demonstrated the characteristic rim sign, a photopenic defect surrounded by a rim of mildly increased activity immediately adjacent to the gallbladder fossa. The rim sign was thought to be the result of reactive inflammation in the hepatic tissue adjacent to a postoperative abscess within the gallbladder fossa. PMID:26111711

    Gallbladder tuberculosis (GT) is an extremely rare condition. This is thought to be due to the protective property of bile against the infection. Clinical and radiological diagnosis of GT is difficult. We describe a case of GT who initially presented to us with jaundice, a right hypochondrial mass and computed tomographic findings suggestive of gallbladder empyema. Diagnosis was made from histopathological examination of the resected gallbladder which revealed epitheloid granulomas with caseating necrosis and presence of Langhan's giant cells. From a literature search and to the best of our knowledge, this is the first GT to be reported in South East Asia. PMID:22106698

  12. Gastric emptying abnormal in duodenal ulcer

    International Nuclear Information System (INIS)

    To investigate the possibility that an abnormality of gastric emptying exists in duodenal ulcer and to determine if such an abnormality persists after ulcer healing, scintigraphic gastric emptying measurements were undertaken in 16 duodenal ulcer patients before, during, and after therapy with cimetidine; in 12 patients with pernicious anemia, and in 12 control subjects. No difference was detected in the rate or pattern of gastric emptying in duodenal ulcer patients before and after ulcer healing with cimetidine compared with controls, but emptying of the solid component of the test meal was more rapid during treatment with the drug. Comparison of emptying patterns obtained in duodenal ulcer subjects during and after cimetidine treatment with those obtained in pernicious anemia patients and controls revealed a similar relationship that was characterized by a tendency for reduction in the normal differentiation between the emptying of solid and liquid from the stomach. The similarity in emptying patterns in these groups of subjects suggests that gastric emptying of solids may be influenced by changes in the volume of gastric secretion. The failure to detect an abnormality of gastric emptying in duodenal ulcer subjects before and after ulcer healing calls into question the widespread belief that abnormally rapid gastric emptying is a feature with pathogenetic significance in duodenal ulcer disease

  13. 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.

    Full Text Available Background/Aim: Ascariasis is a common parasitic infestation in Asia and Latin America. The most serious presentation is biliary and pancreatic ascariasis (BPA. The aim of the present study was to compare the clinical presentation of BPA with dead worms with that with living worms. Materials and Methods: We included 138 consecutive cases of BPA that occured during the period January 2005 to July 2009. All the patients had endoscopically proven BPA consisting of living or dead worms. Comparison was done by chi-square and independent t tests. Results: The age (mean ± SD of the patients was 36.8 ± 16.1 years. Prevalence ratio between male and female patients was 1:5. Ninety eight patients contained living worms and 40 had dead worms. Males were more prone to develop dead worm BPA. The commonest presentation was biliary colic (131; 94.9%; others were acute cholangitis (30; 21.7%, obstructive jaundice (19; 13.8%, choledocholithiasis (20; 14.5%, acute pancreatitis (10; 7.2%, acute cholecystitis (6; 4.3%, liver abscess (2; 1.4%, hepatolithiasis (3; 2.2%, stricture of common bile duct (2; 1.4%, pancreatic abscess (1; 0.7% and cirrhosis of liver (1; 0.7%. Choledocholithiasis, hepatolithiasis, liver abscess and cirrhosis were associated only with dead worms. We could successfully remove all the worms with endoscopic interventions, but 5 patients required surgical intervention as there were strictures and stones within the biliary tree or Ascaris were in gallbladder. Recurrences of stone and cholangitis occurred only in those with dead worms. Conclusion: Biliary ascariasis with dead worms is more dangerous than that with living worms. Endoscopic or surgical intervention may be required repeatedly in those with dead worms.

    As a result of important advances in medical imaging, the oral cholecystogram is no longer the primary test of gallbladder function and anatomy. Real-time ultrasonography and cholescintigraphy, both highly sensitive and specific tests, are the two major methods for assessing gallbladder pathology. Oral cholecystography, endoscopic retrograde pancreatography, and percutaneous gallbladder puncture serve as supplementary tests. Decisions about which test to use depend on the kind of gallbladder disease that is suspected as well as the estimated likelihood of the disease before the information is obtained from the procedure. Thus, ultrasonography is the test of choice for chronic cholecystitis, with oral cholecystography reserved for situations in which the diagnosis is uncertain after ultrasonography. When acute cholecystitis is suspected, ultrasonography is also the test of choice in most patients, and cholescintigraphy is used to resolve uncertainty. 103 references.

  19. Oxygen radicals stimulate guinea pig gallbladder glycoprotein secretion in vitro

    International Nuclear Information System (INIS)

    In several animal models of cholelithiasis, and in humans with gallstones, hypersecretion of gallbladder mucin is observed. This study was undertaken to determine the effect of oxygen radicals on guinea pig gallbladder glycoprotein secretion in organ culture. Mucosal explants were incubated with [3H]glucosamine hydrochloride to label glycoproteins, then exposed to oxygen radicals generated by chelated ferric iron and ascorbic acid. Marked stimulation of glycoprotein release was observed after a 30-min exposure to the oxygen radical-generating system, and the effect was inhibited by mannitol. The stimulatory effect of hydroxyl radical was not accompanied by leakage of intracellular lactate dehydrogenase. Parallel experiments with human granulocytes activated with f-Met-Leu-Phe and coincubated with gallbladder explants revealed similar results. These results indicate that oxygen radicals, especially the hydroxyl radical (OH), are capable of stimulating rapid release of mucous-type glycoproteins from gallbladder epithelium

    The accessory liver lobe (ALL) of the gallbladder wall is rare, mentioned by Meckel since 1822. We present two cases of ALL occurring in two adult women. The ALLs were diagnosed at microscopic examination of cholecystectomy specimens for lithiasic cholecystitis and were located at the gallbladder body level. They measured 0.5 and 1.1 cm and were pediculated from the gallbladder serosa. Luschka duct complexes were seen in the adjacent subserosa in one of the cases. The main clinical relevance of ALL of the gallbladder resides in the differential diagnosis with a lymph node and in the risk of peroperative hemorragia or bile leakage by sectioning of the connecting blood vessels and/or bile duct. Intraparietal ALL may interfere with dysmotility, possibly resulting in bile stagnation and stone formation. PMID:27147442

    It was investigated the influence of dietary therapy with enteral formula "Nutricomp AND Braum fiber" on clinical and biochemic parameters in biliary tract diseases. Also it was carried out the comparative estimation of the gallbladder motility in this contingent of patients in process of the standard food loading and the loading with the tested enteral formula (25 g carbohydrates). It was indicated that the including of enteral formula "Nutricomp AND Braum fiber" (209 g/day) in traditional hypocaloric diet promotes the decrease of cholesterol level and activity of alkaline phosphatase. The gallbladder motility was some smaller after the consuming of enteral formula "Nutricomp AND Braum Diabetes" compared with the standard food loading (25 g carbohydrates). PMID:16313133

    Full Text Available Abstract Renal cell carcinoma constitutes about 3% of adult malignancies. It has a high metastatic potential associated with synchronous or metachronous metastatic disease. Further, it is known to metastasize mainly to the lung, bone, brain, liver, or adrenal glands. In very rare cases it can metastasize to the gallbladder mimicking acute cholecystitis on clinical exam. In this case we present a patient who developed a gallbladder metastasis five years after a renal cell carcinoma mimicking acute cholecystitis.

  9. 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.)

    2014-01-01

    Full Text Available Introduction. Primary lymphoma of the gallbladder is an extremely rare entity with approximately 50 cases reported so far. In many of these cases the presenting symptoms were mimicking symptomatic gallstone disease and the diagnosis was made postoperatively, especially when the preoperative imaging results were far from suspicious for malignant disease. Patients and Methods. We report a case of primary lymphoma of the gallbladder in an 85-year-old man with gallstone disease, who was admitted for elective cholecystectomy 2 months after an episode of acute cholecystitis and pancreatitis. Histological evaluation of the specimen revealed a small lymphocytic lymphoma of the gallbladder. This type of primary gallbladder lymphoma has not been previously reported. Discussion. The most common primary lymphomas of the gallbladder are MALT lymphomas and diffuse large B-cell lymphomas, although a variety of other histological types have been reported. The association of these lesions with chronic inflammation is the most convincing theory for their pathogenesis. For lesions confined to the gallbladder, cholecystectomy is considered to be sufficient, while supplementary chemotherapy significantly improves prognosis in more advanced disease.

    Full Text Available Context Heterotopic pancreatic tissue is defined as pancreatic tissue outside the boundaries of the pancreas that has neither anatomic nor vascular continuity with the pancreas. Heterotopic pancreatic tissue in the gallbladder is uncommon and has rarely been reported to cause symptoms. We report a case of heterotopic pancreatic tissue obstructing the gallbladder neck resulting in cholecystitis. Case report A 26-year-old female presented with right upper quadrant abdominal pain and fever. On physical examination the right upper quadrant was tender to palpation with a positive Murphy’s sign. Laboratory tests were significant for elevated aspartate aminotransferase and alanine aminotransferase. Transabdominal sonography showed gallbladder wall thickening, a positive sonographic Murphy’s sign, and an apparent large non-mobile stone at the gallbladder neck. Pathologic examination revealed cholecystitis but instead of a large stone there was a tan-yellow necrotic mass at the gallbladder neck. Microscopically, the mass consisted of heterotopic pancreatic tissue containing exocrine pancreatic acini, ducts, and islets of Langerhans. The final diagnosis was acute cholecystitis secondary to obstruction by heterotopic pancreatic tissue. Conclusion Although heterotopic pancreatic tissue is usually an incidental finding on pathologic exam, one should not exclude it in the differential diagnosis of symptomatic gallbladder disease of indefinite etiology.

    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.

    Malignant biliary obstruction is commonly caused by gall bladder carcinoma, cholangiocarcinoma and metastatic nodes. Percutaneous interventions play an important role in managing these patients. Biliary drainage, which forms the major bulk of radiological interventions, can be palliative in inoperable patients or pre-operative to improve liver function prior to surgery. Other interventions include cholecystostomy and radiofrequency ablation. We present here the indications, contraindications, technique and complications of the radiological interventions performed in patients with malignant biliary obstruction. PMID:27247718

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

    Gallbladder cancer (GbCa) is the most frequent malignancy of the biliary tract. It is also the 6th most common gastrointestinal tumor. It is associated with very high lethality, mainly due to the lack of symptoms up to a very late and thus incurable state. As many as 80% of patients are diagnosed at very late stages of disease, which allow only palliative therapy. As a result, most of the patients with GbCa will die within 6 months of the diagnosis, hence the average 5-year survival does not exceed 5%. Currently, surgical resection represents the only curative option in GbCa, but this approach is feasible only at an early stage of the disease. Other oncologic therapies are of limited use. The incidence of GbCa is remarkably increased in certain populations such as Native North Americans, South Indian females and, in Europe, in the Polish population. It is not clear to date if these enhanced risk populations are the result of common environmental exposure or of shared genetic risk factors. In this review we provide an overview of the state-of-art in GbCa research with the focus on the current knowledge concerning genetic and environmental triggers of this tumor. PMID:26405706

  4. Cholescintigraphy, ultrasonography and computerized tomography in the evaluation of biliary tract disorders

    International Nuclear Information System (INIS)

    Newer modalities available for the evaluation of hepatobiliary disease include cholescintigraphy, ultrasonography, and computerized tomography. We have examined the relative strengths and weaknesses of each of these noninvasive techniques and developed a rational diagnostic approach for the evaluation of acute cholecystitis, chronic cholecystitis, and cholestasis. The procedure of choice for suspected acute cholecystitis is /sup 99m/Tc-HIDA cholescintigraphy because it is a highly accurate method for obtaining functional information with regard to cystic duct patency. In suspected chronic cholecystitis, the oral cholecystogram is the best screening procedure, followed by ultrasound for confirmation of gallbladder disease as the cause of nonvisualizaion. The role of /sup 99m/Tc-HIDA cholescintigraphy in suspected chronic cholecystitis is limited to those cases where the oral cholecystogram and sonogram yield disparate results, or where a patient is known to have chronic gallbladder disease and super-imposed acute exacerbation is suspected. Ultrasonography is recommended as the initial procedure for evaluation of the patient with cholestasis. It is highly accurate in distinguishing hepatocellular disease from obstructive jaundice, and when dilated biliary radicles are visualized, ultrasonography is frequently capable of identifying the cause of obstruction. If the patient's body habitus or gaseous distention makes ultrasonographic evaluation difficult, then computerized tomography is recommended, followed by endoscopic retrograde cholangiopancreatography or transhepatic cholangiography, when needed

    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.

    Gallbladder small cell carcinoma (SCC) comprises only 0.5 % of all gallbladder cancer and consists of aggressive tumors with poor survival outcomes against current treatments. These tumors are most common in elderly females, particularly those with cholecystolithiasis. We report the case of a 79-year-old woman with gallbladder small cell carcinoma. The patient had intermittent right upper quadrant abdominal pain and was admitted to our hospital due to suspected acute cholecystitis. She regularly received medical treatment for diabetes, hypertension, and dyslipidemia. On initial laboratory evaluation, the levels of aspartate aminotransferase (AST), total bilirubin, and C-reactive protein (CRP) were markedly elevated. She underwent computed tomography (CT) for screening. CT images showed a thick-walled gallbladder containing multiple stones and multiple 3-cm-sized round nodular lesions, which were suggestive of metastatic lymph nodes. After percutaneous transhepatic gallbladder drainage was performed, endoscopic ultrasound-guided fine needle aspiration of enlarged lymph nodes resulted in a diagnosis of small cell carcinoma or adenocarcinoma. However, we could not identify the primary lesion before the surgery because of no decisive factors. We performed cholecystectomy because there was a possibility of cholecystitis recurrence risk and also partial liver resection because we suspected tumor invasion. The final pathological diagnosis was neuroendocrine carcinoma of the gallbladder, small cell type. The tumor stage was IVb, T3aN1M1. The patient died 13 weeks after the surgery. In the present paper, we review the current available English-language literature of gallbladder SCC. PMID:27457076

  7. Ultrasonographic and scintigraphic assessment of gallbladder motility alterations induced by octreotide's therapy

    International Nuclear Information System (INIS)

    Octreotide treatment may be associated with gallstone development in 26% of acromegalic patients. The mechanism of octreotide-associated gallstone formation may involve an impaired gallbladder (GB) emptying. We defined new parameters of GB motor function by using cholescintigraphy (CS) and ultrasonography (US) simultaneously: absolute emptying (CS) and net volume changes (US) were assessed in basal conditions and after octreotide injection. Eight consecutive newly diagnosed acromegalic patients (4 women and 4 men; mean age 46.2 yr) and 8 healthy controls matched by sex, BMI and age, were evaluated. In acromegalic patients (all macroadenoma at MRI) the study was performed in basal conditions and 1 hr after s.c. octreotide injection (100 microgram). GB motility was evaluated at 10-min intervals for 90 min after a standard meal. Cumulative postprandial GB refilling represents the total amount of hepatic bile entering the GB during the 90-min study period. GB turnover was defined as the volume of bile handled in the postprandial period. GB turnover index should indicate the overall performance efficiency of the GB. Mean GB basal volume was sightly but not significantly higher in acromegalic (36.6 ml) as compared to controls (19.3 ml). Mean GB emptying (by US) was similar in acromegalics and in controls (72.4 vs 74.0 by CS and, 35.8 vs 35.0 by US). Postprandial GB refilling within 50 minutes was significantly reduced in acromegalics compared to controls (p<0.001). Mean turnover index tended to be lower in acromegalic than in controls (2.2 vs 3.1). Octreotide administration in acromegalic patients, induced a significant reduction in: GB emptying (both by US and CS), postprandial refilling and bile turnover. These results demonstrate an impaired GB motility in acromegalics, which is worsened by acute octreotide administration. Our data suggest that turnover index can be a reliable means of recognizing acromegalic patients who may develop gallstone disease under OC

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

  13. 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

    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.

  15. Application of DSA guidance combined with ultrasound localization in performing percutaneous transhepatic biliary drainage

    International Nuclear Information System (INIS)

    Objective: To investigate the application of DSA guidance combined with ultrasound localization in performing percutaneous transhepatic biliary drainage (PTBD). Methods: A total of 32 cases with malignant obstructive jaundice were enrolled in this study. The primary malignancy included primary liver cancer (n=4), bile duct carcinoma (n=21), gallbladder carcinoma with hepatic hilar metastases (n=2), metastatic carcinoma (n=3) and adenocarcinoma of the head of pancreas (n=2). Palliative biliary tract external and/or internal drainage were carried out under DSA guidance together with ultrasonic localization. After the treatment, all the routine biochemical items were reexamined. The results were analyzed. Results: Successful puncturing and drainage with single manipulation was achieved in all the 32 patients, and the success rate was 100%. External drainage was employed in 21 cases, while external together with internal drainage was adopted in 11 cases. After the operation, the jaundice was reduced, the liver function and clinical symptoms were relieved, and the patient's living quality was improved. Conclusion: With the help of DSA guidance combined with ultrasound localization the technical success rate of PTBD can be greatly improved and the operation time can be shortened. This technique is safe and effective, and it is very helpful in reducing patient's suffering. Meanwhile, the exposure dose of irradiation can be lessened to a large extent. (authors)

    Full Text Available Hepatomegaly, decrease in the liver paranchymal echo and increase in the gallbladder wall thickness has been shown in acute viral hepatitis. The present study was done to determine sonographic changes in acute viral hepatitis. We performed liver and bile ducts sonography and specific tests on 42 patients (mean age: 31.5 and 61% male with acute viral hepatitis. Gallbladder wall thickness was seen in 45.2% and hepatomegaly in 33.3% of patients and liver paranchymal echo was decreased in 19.3%. Age, sex, type of hepatitis, cholecystitis like symptoms, aspartate aminotransfrase, alanine aminotransfrase, alkaline phosphatase and bilirubin did not significantly corralate with these changes. Only raised prothrombin time was strongly correlated to the thickening of the gallbladder and decrease in the liver paranchymal echo and cholesistic like symptoms we can postulate that thickening of the gallbladder and decrease in the liver paranchymal echo is not dependent on the severity and speed of the paranchymal necrosis (as considered with ALT and AST but they depend on the liver function disturbance (as considered with PT because the thickening of the gall bladder is present in 45% of the patients and 10% of the normal population have gallbladder stones, one should not perform the diagnosis of acute cholecystitis, only on the basis of sonographic report without attention to the clinical and laboratory data.

  17. New approach to gallbladder ultrasonic images analysis and lesions recognition.

    This paper presents a new approach to gallbladder ultrasonic image processing and analysis towards detection of disease symptoms on processed images. First, in this paper, there is presented a new method of filtering gallbladder contours from USG images. A major stage in this filtration is to segment and section off areas occupied by the said organ. In most cases this procedure is based on filtration that plays a key role in the process of diagnosing pathological changes. Unfortunately ultrasound images present among the most troublesome methods of analysis owing to the echogenic inconsistency of structures under observation. This paper provides for an inventive algorithm for the holistic extraction of gallbladder image contours. The algorithm is based on rank filtration, as well as on the analysis of histogram sections on tested organs. The second part concerns detecting lesion symptoms of the gallbladder. Automating a process of diagnosis always comes down to developing algorithms used to analyze the object of such diagnosis and verify the occurrence of symptoms related to given affection. Usually the final stage is to make a diagnosis based on the detected symptoms. This last stage can be carried out through either dedicated expert systems or more classic pattern analysis approach like using rules to determine illness basing on detected symptoms. This paper discusses the pattern analysis algorithms for gallbladder image interpretation towards classification of the most frequent illness symptoms of this organ. PMID:19124224

    In acute stage of virus hepatitis B patients often complain of dyspeptic discomfort. They may be a consequence of alimentary tract motor activity disorders including these of gallbladder. Routine ultrasonography in an early phase of virus hepatitis often reveals gallbladder wall thickening what may confirm the above thesis. Thus, a group of 15 patients in an acute phase of virus hepatitis B was subjected to examinations. Gallbladder motor activity was assessed by ultrasonographic method determining its total volume and ejection fraction and volume after test meal stimulus. First examination was performed in the first week since the appearance of yellowing of the walls, successive in 4 and 8 week of the disease. Obtained results were compared to the values obtained in the group of 25 healthy volunteers. It was found out that gallbladder volume was significantly decreased and ejection fraction increased in the acute phase of virus hepatitis B than in the controls. This may speak for gallbladder hyperreactivity in patients in the course of virus hepatitis B. These disorders decreased during two-month observation but even in the 8 week the investigated parameters differed from those found in the control group. PMID:15058248

    Six cases of nonvisulization of the gallbladder lumen in patients with acute viral hepatitis are presented. Follow-up ultrasonographic examinations done during the convalescent period in 2 patients showed normal gallbladders and this was correlated with improvement in enzyme levels. It is suggested that acute viral hepatitis should be considered in the differential diagnosis of nonvisualization of the gallbladder lumen on sonogram.

    @@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.

  2. Do calories or osmolality determine gastric emptying

    International Nuclear Information System (INIS)

    Recent animal studies suggest that gastric emptying is dependent on the caloric and osmotic content of the ingested food. These studies have involved intubation with infusion of liquid meals into the stomach. Scintigraphic methods, which are non-invasive and do not alter normal physiology, are now available for precise quantitation of gastric emptying. To study the role of calories and osmolality on gastric emptying, the authors employed a standardized /sup 99m/Tc-scrambled egg meal washed with 50 cc tap water in 10 normal human volunteers. A variety of simple and complex sugars, non-absorbable complex carbohydrate (polycose), medium chain fatty acid (MCFA) and gluten were dissolved in water and ingested with the test meal. Each subject acted as his own control. Coefficient of variation in control tests in each subject 12 weeks apart was 9.9%. Results showed that incremental glucose (25-66 gm) produced a linear increase in gastric emptying (T/2 control 50 +- 3, 25 gm 60 +- 3, 50 gm 79 +- 3 and 66 gm 102 +- 3 minutes). 25 gm fructose (T/2 59 +- 3 minutes) and 25 gm polycose (T/2 59 +- 3 minutes) had similar effects to glucose. 25 gm sucrose and 25 gm gluten did not significantly differ from controls. MCFA had an effect similar to 50 gm glucose - suggesting that calories are important in gastric emptying. However, 25 gm xylose markedly prolonged gastric emptying to 80 +- 5 minutes. The rank order for osmolality for substances tested MCFA = gluten < polycose < polycose < fructose < sucrose = glucose < xylose defined no relationship to gastric emptying. The authors' results suggest that neither calories nor osmolality alone determine gastric emptying. A specific food does not necessarily have the same effect on gastric emptying in different individuals

    A variety of radionuclide-labeled, solid foods have been used to measure gastric emptying. Implicit is the idea that the nuclide label identifies the rate of emptying of meal contents. The present studies tested whether different foods empty from the human stomach at different rates. Eight volunteers were fed meals of 200 ml of water + 213 g of beef stew + 52 g of chicken liver, with half the liver as 0.25-mm particles and half as 10-mm chunks, labeled with /sup 99m/Tc and /sup 113m/In, respectively, or the reverse. Another 8 subjects ingested 200 ml of water + 75 g of noodles, labeled with /sup 123/I, + 30 g of liver, labeled with /sup 113/In. Gastric emptying of each radionuclide was determined for 3 h by measuring the decline of counts in the gastric region of interest, using an Ohio Nuclear S410 gamma camera interfaced to a DEC computer. In each case, appropriate corrections were made for nuclear decay, down-scatter from /sup 113m/In, and septal penetration. Seven of 8 subjects emptied 0.25-mm liver particles more quickly than 10-mm chunks of liver, while 1 subject emptied the two sizes of liver at the same rate. The t 1/2 for the 0.25-mm liver was 70 +/- 10 min; and for the 10-mm liver, 117 +/- 19 min (p less than 0.05). Six of 8 subjects emptied noodles much faster than liver, while 2 emptied the two foods at similar rates. The t 1/2 for the noodles was 52 +/- 8 min; and for the liver, 82 +/- 5 min (p less than 0.02). Since different foods in the same meal were found to empty at different rates, we conclude the gastric emptying of every food in a meal is not accurately represented by the emptying of a single, nuclide-labeled food. The different t 1/2s for the emptying of 10-mm liver in the two meals (p less than 0.05) probably reflected the influence of other meal components on gastric motility.

  5. The role of radiotherapy for carcinomas of the gall bladder and extrahepatic biliary duct : retrospective analysis

    International Nuclear Information System (INIS)

    Carcinomas arising in the gall bladder(GB) or extrahepatic biliary ducts are uncommon and generally have a poor prognosis. The overall 5-year survival rates are less than 10%. Early experiences with the external radiation therapy demonstrated a good palliation with occasional long-term survival. The present report describes our experience over the past decade with irradiation of primary carcinomas of the gallbladder and extrahepatic biliary duct. From Feb. 1984 to Nov. 1995, thirty-three patients with carcinoma of the GB and extrahepatic biliary duct were treated with external beam radiotherapy with curative intent at our institution. All patients were treated with 4-MV linear accelerator and radiation dose ranged from 31.44Gy to 54.87Gy(median 44.25Gy), and three patients received additional intraluminal brachytherapy(range, 25Gy to 30Gy). Twenty-seven patients received postoperative radiation. Among 27 patients, Sixteen patients underwent radical operation with curative aim and the rest of the patients either had bypass surgery or biopsy alone. In seventeen patients, adjuvant chemotherapy was used and eleven patients were treated with 5-FU, mitomycin and leucovorin. Median follow up period was 8.5 months(range 2-97 months). The overall 2-year and 5-year survival rates in all patients were 29.9% and 13.3% respectively. In patients with GB and extrahepatic biliary duct carcinomas, the 2-year survival rates were 34.5% and 27.8% respectively. Patients who underwent radical operation showed better 2-year survival rates than those who underwent palliative operation(43.8% vs. 20.7%), albeit statistically insignificant(p>0.05). The 2-year survival rates in Stage I and II were higher than in Stage III and IV with statistical significance(p0.05). The survival of patients with relatively lower stage and/or initial good performance was significantly superior to that of others. We found an statistically insignificant trend toward better survival in patients with radical

    A technique for the investigation of suspected non-acute gallbladder disease is described. It is based on properly conducted oral cholecystography (OCG) augmented, when necessary, by ultrasonic examination of the gallbladder (UCG) during the patient's same visit. This regimen has been applied successfully for 5 years; the results of a recent year's work are presented and discussed. Only 12.2% of patients required both investigations and, using the OCG technique described, in only 1.1% of cases was the gallbladder inadequately opacified when subsequent UCG was normal. This approach involves no increase in work-load and provides the referring clinician with objective evidence of the presence or absence of disease following a single visit by the patient to the X-ray department.

    Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancy. 25% to 57% of RCC patients exhibit overt evidence of metastatic disease at initial presentation. Metastases to the gallbladder is uncommon and usually detected in only 0.4-0.6% of autopsies. We report the case of a 58 year old man who presented with a metastasis in the gallbladder from RCC. He had undergone went a right nephrectomy four years ago. There was no evidence of metastasis. A follow up abdomen CT scan taken three years after operation showed a polypoid lesion within the gallbladder. The size of the polypoid lesion had increased at the follow up CT and the enhancement pattern of lesion became similar to that of RCC. A Cholecystectomy was performed. Histopathological examination revealed the polyp was clear cell carcinoma of metastatic origin from kidney.

    AIM: To evaluate the effect of preoperative biliary drainage(PBD) on obstructive jaundice resulting from malignant tumors.METHODS: According to the requirements of Cochrane systematic review, studies in the English language were retrieved from MEDLINE and Embase databases from 1995 to 2009 with the key word "preoperative biliary drainage". Two reviewers independently screened the eligible studies, evaluated their academic level and extracted the data from the eligible studies confirmed by cross-checking. Data about patients with and without PBD after resection of malignant tumors were processed for meta-analysis using the Stata 9.2 software, including postoperative mortality, incidence of postoperative pancreatic and bile leakage, abdominal abscess, delayed gastric emptying and incision infection.RESULTS: Fourteen retrospective cohort studies involving 1826 patients with malignant obstructive jaundice accorded with our inclusion criteria, and were included in meta-analysis. Their baseline characteristics were comparable in all the studies. No significant difference was found in combined risk ratio (RR) of postoperative mortality and incidence of pancreatic and bile leakage, abdominal abscess, delayed gastric emptying between patients with and without PBD. However, the combined RR for the incidence of postoperative incision infectionwas improved better in patients with PBD than in those without PBD (P<0.05).CONCLUSION: PBD cannot significantly reduce the postoperative mortality and complications of malignant obstructive jaundice, and therefore should not be used as a preoperative routine procedure for malignant obstructive jaundice.

    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: 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 tract cancers are aggressive tumors of which the incidence seems to increase. Resection with cancer-free margins is crucial for curative therapy. However, how often biliary intraepithelial neoplasia (BilIN) occurs in resection margins and what its clinical and therapeutic implications might be is largely unknown. We reexamined margins of resection specimens of adenocarcinoma of the biliary tree including the gallbladder for the presence of BilIN. When present, it was graded. The findings were correlated with clinicopathological parameters and overall survival. Complete examination of the resection margin could be performed on 55 of 78 specimens (71%). BilIN was detected in the margin in 29 specimens (53%) and was mainly low-grade (BilIN-1; N = 14 of 29; 48%). In resection specimens of extrahepatic cholangiocarcinoma, BilIN was most frequent (N = 6 of 8; 75%). BilIN was found in the resection margin more frequently in extrahepatic cholangiocarcinomas (P = 0.007) and in large primary tumors (P = 0.001) with lymphovascular (P = 0.006) and perineural invasion (P = 0.049). Patients with cancer in the resection margin (R1) had a significantly shorter overall survival than those with resection margins free of tumor (R0) irrespective of the presence of BilIN (R0 vs R1; P < 0.001) or BilIN grade (BilIN-positive vs BilIN-negative, P = 0.6, and BilIN-1 + 2 vs BilIN-3, P = 0.58). BilIN is frequently found in the surgical margin of resection specimens of adenocarcinoma of the biliary tract. Hepatopancreatobiliary surgeons will be confronted with this recently defined entity when an intraoperative frozen section of a resection margin is requested. However, this diagnosis does not require additional resection and in the intraoperative evaluation of resection, the emphasis should remain on the detection of residual invasive tumor. PMID:25425476

    An empty spot refers to an empty hard-to-fill space which can be found in the records of the social interaction, and is the clue to the persons in the underlying social network who do not appear in the records. This contribution addresses a problem to predict relevant empty spots in social interaction. Homogeneous and inhomogeneous networks are studied as a model underlying the social interaction. A heuristic predictor function method is presented as a new method to address the problem. Simulation experiment is demonstrated over a homogeneous network. A test data set in the form of market baskets is generated from the simulated communication. Precision to predict the empty spots is calculated to demonstrate the performance of the presented method.

  17. Gastric emptying of enteric-coated tablets

    International Nuclear Information System (INIS)

    To evaluate the gastric emptying time of pharmaceutical dosage forms in a clinical setting, a relatively simple dual-radionuclide technique was developed. Placebo tablets of six different combinations of shape and size were labeled with indium-111 DTPA and enteric coated. Six volunteers participated in a single-blind and crossover study. Tablets were given in the morning of a fasting stomach with 6 oz of water containing /sup 99m/Tc pertechnetate and continuously observed with a gamma camera. A scintigraph was obtained each minute. The results suggested that the size, shape, or volume of the tablet used in this study had no significant effect in the rate of gastric emptying. The tablets emptied erratically and unpredictably, depending upon their time of arrival in the stomach in relation to the occurrence of interdigestive myoelectric contractions. The method described is a relatively simple and accurate technique to allow one to follow the gastric emptying of tablets

    Full Text Available Context Heterotopic pancreas of the gallbladder is an extremely rare entity, especially when pancreatic tissue appears histologically with an exclusively exocrine structure. Case report We report the case of a 35-year-old man who presented with symptoms of acalculous gallbladder disease with high levels of amylasuria. Immunohistochemical analysis of the surgical specimen of the cholecystectomy revealed pancreatic tissue at the gallbladder wall. Conclusions Heterotopic pancreatic tissue is a rare pathological finding in the gallbladder. It requires consideration and sensitization in the differential diagnosis of acalculous gallbladder disease, which can explain hyperamylasuria in cases of unknown origin.

    Most of gallbladder tumors are benign. Adenoma, cholesterol polyps, or adenomyomatosis are most frequently typical on ultrasonographic images. All symptomatic lesions must be considered as indications for surgery. It may be difficult to identify precancerous or malignant lesion. Polyps over 1cm are indication for preventive cholecystectomy. In case of suspicious polyp or suspicious wall thickening, endoscopic ultrasonography can be helpful to evaluate local tumoral spread and eliminate differential diagnosis. Unfortunately, diagnosis of gallbladder cancer is often late, when surgical resection can't be curative. Computed tomography and magnetic resonance imaging examinations are then useful for local and metastatic staging. PMID:18954953

    A 17-year-old girl with colicky abdominal pain and chronic anemia presented to the gastrointestinal service of the University Hospital of Essen. In the routine workup, there were no pathological findings despite the anemia. Because of the fluctuation of symptoms with a climax at the time of menstruation, consecutive ultrasound studies were performed revealing a visible mass inside the gallbladder. This finding was confirmed by a magnetic resonance imaging (MRI) study performed at the same time. Because of the severe anemia by that time, a cholecystectomy was performed, and histology reconfirmed the diagnosis of isolated gallbladder endometriosis. The patient recovered well and has had no recurrence of the disease to date.

    The objective of this study was to investigate the effects of different preoperative biliary drainage (PBD) methods on complications in jaundiced patients following pancreaticoduodenectomy. We retrospectively analyzed 270 extrahepatic bile duct cancer patients who underwent pancreaticoduodenectomy. A total of 170 patients without PBD treatment were defined as the non-PBD group. According to different PBD methods, 45, 18, and 37 patients were classified into the percutaneous transhepatic biliary drainage (PTBD), endoscopic nasobiliary drainage (ENBD), and endoscopic retrograde biliary stent (ERBS) groups, respectively. Clinical characteristics and complications were compared among the 4 groups. Preoperative cholangitis occurred in 14 (8.2%) and 8 (21.6%) patients in the non-PBD and ERBS group, respectively (P = 0.04). Compared with the non-PBD group, delayed gastric emptying (DGE) and wound infection occurred significantly more often in the ERBS group. The incidence of severe complications was significantly lower in the PTBD group than the non-PBD group (P = 0.03). Postoperative hospital stay and complication rates were significantly higher in the ERBS group than the PTBD group. There were no significant differences in complications between ENBD and other groups. In conclusion, PTBD can improve surgical outcomes by reducing severe complication rate in jaundiced patients following pancreaticoduodenectomy. ERBS increased the rates of DGE and wound infection due to high incidence of cholangitis before operative intervention and should be avoided. ENBD carried no special effect on complications and needs further analysis. PMID:25860221

  8. Inaccurate preoperative imaging assessment on biliary anatomy not increases biliary complications after living donor liver transplantation

    International Nuclear Information System (INIS)

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

    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)

  11. Distinguishing benign from malignant gallbladder wall thickening using FDG-PET

    International Nuclear Information System (INIS)

    Because thickening of the gallbladder wall is observed not only in patients with gallbladder cancer but also in those with benign diseases such as chronic cholecystitis and gallbladder adenomyosis, it is difficult to distinguish between benign and malignant gallbladder wall thickening by conventional techniques of diagnostic imaging such as computed tomography (CT), magnetic resonance imaging (MRI), and abdominal ultrasonography (US). In the present study, we attempted to distinguish between benign and malignant gallbladder wall thickening by means of fluorine-18-fluorodeoxyglucose (FDG)-Positron emission tomography (PET). FDG-PET was performed in 12 patients with gallbladder wall thickening detected by CT or US, to determine whether it was benign or malignant. Emission scans were taken, beginning 45 minutes after intravenous administration of FDG, and standardized uptake value (SUV) was calculated as an indicator of glucose metabolism. Of the 12 patients, 4 showed positive uptake of FDG in the gallbladder wall. Of these 4 patients, 3 had gallbladder cancer. The remaining one, who had chronic cholecystitis, had false-positive findings. The other 8 patients had negative uptake of FDG in the gallbladder wall. Two of these 8 underwent surgical resection, which yielded a diagnosis of chronic cholecystitis. The other 6 patients exhibited no sign of gallbladder malignancy and have been followed without active treatment. FDG-PET appears able to distinguish between benign and malignant gallbladder wall thickening. (author)

  12. CD133 promotes gallbladder carcinoma cell migration through activating Akt phosphorylation

    Gallbladder carcinoma (GBC) is the fifth most common malignancy of gastrointestinal tract. The prognosis of gallbladder carcinoma is extremely terrible partially due to metastasis. However, the mechanisms underlying gallbladder carcinoma metastasis remain largely unknown. CD133 is a widely used cancer stem cell marker including in gallbladder carcinoma. Here, we found that CD133 was highly expressed in gallbladder carcinoma as compared to normal tissues. CD133 was located in the invasive areas in gallbladder carcinoma. Down-regulation expression of CD133 inhibited migration and invasion of gallbladder carcinoma cell without obviously reducing cell proliferation. Mechanism analysis revealed that down-regulation expression of CD133 inhibited Akt phosphorylation and increased PTEN protein level. The inhibitory effect of CD133 down-regulation on gallbladder carcinoma cell migration could be rescued by Akt activation. Consistent with this, addition of Akt inhibitor Wortmannin markedly inhibited the migration ability of CD133-overexpressing cells. Thus, down-regulation of CD133 inhibits migration of gallbladder carcinoma cells through reducing Akt phosphorylation. These findings explore the fundamental biological aspect of CD133 in gallbladder carcinoma progression, providing insights into gallbladder carcinoma cell migration. PMID:26910892

  19. Benign Biliary Strictures: Diagnostic Evaluation and Approaches to Percutaneous Treatment.

    Fidelman, Nicholas

    2015-12-01

    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.

  20. Acute gallbladder torsion - a continued pre-operative diagnostic dilemma

    2011-04-01

    Full Text Available Abstract Acute gallbladder volvulus continues to remain a relatively uncommon process, manifesting itself usually during exploration for an acute surgical abdomen with a presumptive diagnosis of acute cholecystitis. The pathophysiology is that of mechanical organo-axial torsion along the gallbladder's longitudinal axis involving the cystic duct and cystic artery, and with a pre-requisite of local mesenteric redundancy. The demographic tendency is septua- and octo-genarians of the female sex, and its overall incidence is increasing, this being attributed to increasing life expectancy. We discuss two cases of elderly, fragile women presenting to the emergency department complaining of sudden onset right upper quadrant abdominal pain. Their subsequent evaluation suggested acute cholecystitis. Ultimately both were taken to the operating room where the correct diagnosis of gallbladder torsion was made. Pre-operative diagnosis continues to be a major challenge with only 4 cases reported in the literature diagnosed with pre-operative imaging; the remainder were found intra-operatively. Consequently, a delay in diagnosis can have devastating patient outcomes. Herein we propose a necessary high index of suspicion for gallbladder volvulus in the outlined patient demographic with symptoms and signs mimicking acute cholecystitis.

  4. Work in progress: nuclear magnetic resonance imaging of the gallbladder

    International Nuclear Information System (INIS)

    A preliminary study of the relation between food intake and intensity of gallbladder bile on nuclear magnetic resonance (NMR) images was made. Twelve subjects (seven volunteers, five patients) were imaged following a minimum of 14 hours of fasting. Six of seven volunteers were reimaged one hour after stimulation by either a fatty meal or an alcoholic beverage. An additional seven patients were imaged two hours after a hospital breakfast. It was found that concentrated bile emits a high-intensity spin echo signal (SE), while hepatic bile in the gallbladder produces a low-intensity SE signal. Following ingestion of cholecystogogue, dilute hepatic bile settles on top of the concentrated bile, each emitting SE signals of different intensity. The average T1 value of concentrated bile was 594 msec, while the T1 vaue of dilute hepatic bile was 2,646 msec. The average T2 values were 104 msec for concentrated bile and 126 msec for dilute bile. The most likely cause for the different SE intensities of bile is the higher water content, and therefore longer T1 or T2 relaxation times, of hepatic bile. It is suggested that NMR imaging has the ability to provide physiological information about the gallbladder and that it may prove to be a simple and safe clinical test of gallbladder function

    Laparoscopic surgery has been widely accepted as a feasible and safe treatment modality in many cancers of the gastrointestinal tract. However, most guidelines on gallbladder cancer (GBC) regard laparoscopic surgery as a contraindication, even for early GBC. This study aims to evaluate and compare recent surgical outcomes of laparoscopic and open surgery for T1(a,b) GBC and to determine the optimal surgical strategy for T1 GBC.The study enrolled 197 patients with histopathologically proven T1 GBC and no history of other cancers who underwent surgery from 2000 to 2014 at 3 major tertiary referral hospitals with specialized biliary-pancreas pathologists and optimal pathologic handling protocols. Median follow-up was 56 months. The effects of depth of invasion and type of surgery on disease-specific survival and recurrence patterns were investigated.Of the 197 patients, 116 (58.9%) underwent simple cholecystectomy, including 31 (15.7%) who underwent open cholecystectomy and 85 (43.1%) laparoscopic cholecystectomy. The remaining 81 (41.1%) patients underwent extended cholecystectomy. Five-year disease-specific survival rates were similar in patients who underwent simple and extended cholecystectomy (96.7% vs 100%, P = 0.483), as well as being similar in patients in the simple cholecystectomy group who underwent open and laparoscopic cholecystectomy (100% vs 97.6%, P = 0.543). Type of surgery had no effect on recurrence patterns.Laparoscopic cholecystectomy for T1 gallbladder cancer can provide similar survival outcomes compared to open surgery. Considering less blood loss and shorter hospital stay with better cosmetic outcome, laparoscopic cholecystectomy can be justified as a standard treatment for T1b as well as T1a gallbladder cancer when done by well-experienced surgeons based on exact pathologic diagnosis.

    Full Text Available Purpose: The aim of this diagnostic observational study was to assess the spread and biological behavior of gallbladder cancer using 64-slice computerized tomography (CT scanner in this particular geographic belt (eastern Uttar Pradesh, western Bihar, and northern Madhya Pradesh provinces of North India. Indians are ethnically and culturally different from their Western counterparts among whom the incidence of this disease is comparatively low. Subjects and Methods: After systemic examination, all patients (87 were subjected to ultrasonographic examination. All cases were histopathologically proven. Confirmed cases were subjected to volumetric CT examination of abdomen and pelvis, plain, post contrast and delayed phase. Results: Majority of the cases were adenocarcinoma. There was female preponderance with majority belonging to fifth and sixth decades. Commonest presentation was diffuse, irregular, enhancing wall thickening in 49.4%. Majority had invasion of liver parenchyma (74.7%. Cholelithiasis was seen in 48.3% cases. Invasion of biliary radicals was high (13.8-18.4%. Eleven cases had invasion of portal vein and tumor thrombus, with hepatic artery invasion in one case. In two cases, both hepatic artery and portal vein invasion was seen. Portal and peripancreatic nodal metastasis was seen in 58.5%. Distant metastasis was reported. Conclusion: Few studies involving the Indian population have attempted to use multi-row detector CT to define the biological behavior of carcinoma gallbladder. The opinion whether the pathology is operable or non-operable can reasonably be given. This large-scale, single-center study gives insight about the epidemiology and biological behavior of carcinoma gallbladder.

    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.

    Gastric emptying of organic acids was studied in 6 healthy mongrel dogs. After chronic esophagostomies were performed according to the method of Komarov, a total of 340 test meals were instilled. Each test meal consisted of 300 ml of 6 different organic acids with decreasing molecular weight and different concentrations. After the experiments were achieved, each dog underwent a proximal gastric vagotomy according to the method of Amdrup, and experiments with citric acid were repeated. The results may be summarized as follows: multiple stepwise regression analysis of the data is consistent with a model in which gastric emptying of organic acids is regulated by 3 receptors. The receptors respond to concentration of the organic acid, the actual volume, and the type of acid. The volume receptor is located in the corpus of the stomach because the effect of volume accelerates the emptying rate after proximal gastric vagotomy while the effects of concentration and type of acid remain unchanged.

  9. Normal range of gastric emptying in children

    International Nuclear Information System (INIS)

    Full text: As part of a larger study looking at gastric emptying times in cystic fibrosis, we assessed the normal range of gastric emptying in a control group of children. Thirteen children (8 girls, 5 boys) aged 4-15 years (mean 10) were studied. Excluded were children with a history of relevant gastrointestinal medical or surgical disease, egg allergy or medication affecting gastric emptying. Imaging was performed at 08.00 h after an overnight fast. The test meal was consumed in under 15 min and comprised one 50 g egg, 80 g commercial pancake mix, 10 ml of polyunsaturated oil, 40 ml of water and 30 g of jam. The meal was labelled with 99Tcm-macroaggregates of albumin. Water (150 ml) was also consumed with the test meal. One minute images of 128 x 128 were acquired over the anterior and posterior projections every 5 min for 30 min, then every 15 min until 90 min with a final image at 120 min. Subjects remained supine for the first 60 min, after which they were allowed to walk around. A time-activity curve was generated using the geometric mean of anterior and posterior activity. The half emptying time ranged from 55 to 107 min (mean 79, ± 2 standard deviations 43-115). Lag time (time for 5% to leave stomach) ranged from 2 to 26 min (mean 10). The percent emptied at 60 min ranged from 47 to 73% (mean 63%). There was no correlation of half emptying time with age. The normal reference range for a test meal of pancakes has been established for 13 normal children

  10. Abnormalities of esophageal and gastric emptying in progressive systemic sclerosis

    International Nuclear Information System (INIS)

    Gastric and esophageal emptying were assessed using scintigraphic techniques in 12 patients with progressive systemic sclerosis and 22 normal volunteers. Esophageal emptying was significantly delayed in the patient group, with 7 of the 12 patients beyond the normal range. Gastric emptying was slower in patients than in controls, with 9 patients being outside the normal range for solid emptying and 7 patients outside the normal range for liquid emptying. Findings from gastric and esophageal emptying tests generally correlated well with symptoms of dysphagia and gastroesophageal reflux. However, 2 patients with normal emptying studies had symptomatic heartburn, and 2 patients with delay of both solid and liquid gastric emptying gave no history of gastroesophageal reflux. Delayed gastric emptying may be an important factor in the development of upper gastrointestinal symptoms in patients with progressive systemic sclerosis

  11. Malignant biliary obstruction treated with metallic stents

    International Nuclear Information System (INIS)

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

    To further validate the Pellet Gastric Emptying Test (PGET) as a marker of gastric emptying, a randomized, four-way crossover study was conducted with 12 healthy subjects. The study consisted of oral co-administration of enteric coated caffeine (CAFF) and acetaminophen (APAP) pellets in four treatment phases: Same Size (100 kcal), Fasted, Small Liquid Meal (100 kcal), and Standard Meal (847 kcal). The time of first appearance of measurable drug marker in plasma, t(initial), was taken as the emptying time for the markers. Co-administration of same size enteric coated pellets of CAFF and APAP (0.7 mm in diameter) revealed no statistically significant differences in t(initial) values indicating that emptying was dependent only on size and not on chemical make-up of the pellets. Co-administration of different size pellets indicated that the smaller 0.7-mm diameter (CAFF) pellets were emptied and absorbed significantly earlier than the larger 3.6-mm diameter (APAP) pellets with both the Small Liquid Meal (by 35 min) and the Standard Meal (by 33 min) (P<0.05). The differences in emptying of the pellets were not significant in the Fasted Phase. The results suggest that the pellet gastric emptying test could prove useful in monitoring changes in transit times in the fasted and fed states and their impact on drug absorption.

    We report one case of adenomatous polyposis of the gallbladder in a 57 year-old woman with Gardner's syndrome presenting with cholangitis. On gross examination the gallbladder contained two calculi and numerous flat or polypoid adenomas less than 1 cm in size. On microscopic examination, the adenomas showed low and high grade intraepithelial neoplasia. Only 10 cases of gallbladder adenomas have been reported in the literature in patients presenting with familial adenomatous polyposis (FAP). Cholecystectomy is usually performed for cholecystitis or cholangitis. These adenomatous gallbladder lesions are discovered late, often when the patient is older than 40. Pathogenesis of gallbladder adenomas is still unclear. It is difficult to assess the risk of malignancy: only 6 cases of gallbladder adenocarcinomas have been reported in patients with FAP.

    Ciliated foregut cyst of gallbladder is a very rare benign cystic lesion. A 39-year-old woman was referred to our hospital after abdominal ultrasonography revealed a cystic lesion of gallbladder. On abdominal ultrasonography and computed tomography, a unilocular cystic lesion was found at right upper quadrant with attachment to the gallbladder neck. The gallbladder with cystic lesion was resected through laparoscopic cholecystectomy. The cystic lesion revealed a unilocular cyst with ciliated cuboidal or columnar epithelium and abundant goblet cells. Pathologic examination is essential to distinguish from other cystic lesions of the gallbladder and avoid unnecessary additional treatment. In the current case report, we presented the clinico-pathologic findings of the ciliated foregut cyst of the gallbladder and review of literature.

    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.

    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 rend...

    Gallbladder cancer (GBC) is the most common malignant tumor of the biliary system. However, the mechanisms underlying its tumor initiation, progression, and metastasis are not yet fully understood. The annexin A4 (ANXA4) gene is highly expressed in GBC tissues and may play an important role in the initiation and progression of this disease. In this study, we examined the up-regulation of ANXA4 in human GBC tissues and cell lines. Elevated ANXA4 correlated well with invasion depth in GBC patients and predicted a poor prognosis. In vitro, GBC-SD and NOZ cells with ANXA4 knockdown demonstrated increased apoptosis and inhibited cell growth, migration, and invasion. Interactions between ANXA4 and nuclear factor-κB (NF-κB) p65 proteins were detected. In vivo, ANXA4 knockdown inhibited tumor growth of GBC cells in nude mice and down-regulated the expression of downstream factors in the NF-κB signaling pathway. Taken together, these data indicate that up-regulation of ANXA4 leads to activation of the NF-κB pathway and its target genes in a feedback regulatory mechanism via the p65 subunit, resulting in tumor growth in GBC.

    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.

    In a prospective, blinded study of 205 patients, oral cholecystography (OCG) and sonography were compared in terms of how well each screened patients for gallbladder diseases. Among 23 patients who had pathologic confirmation of the diagnosis at cholecystectomy, OCG correctly diagnosed 20 cases (87%) while sonography diagnosed 18 (78%). Among 54 patients with an abnormal OCG and/or sonogram, OCG detected 47 (87%) while sonography detected 44 (81%). These small differences in detection rates were not statistically significant. On the basis of these results, we cannot conclude that either sonography or OCG has a diagnostic advantage in screening patients for gallbladder disease. The large numbers of false-negative examinations found on both sonography and OCG suggest that in a patient with persistent symptoms, the alternative study should be performed if the first examination is negative.

  9. Gallbladder disease in patients with primary sclerosing cholangitis

    International Nuclear Information System (INIS)

    The author retrospectively reviewed the records of 121 patients with known primary sclerosing cholangitis. CT scans, US scans, and cholangiograms were reviewed and correlated with surgical or autopsy findings, when available. Gallstones were found in 16 of 55 patients at surgery/autopsy. Acalculous cholecystitis was found in 31 patients, cholesterolosis in three, adenoma in three, and carcinoma in three. In 66 nonoperatively treated patients, gallstones were demonstrated by US in an additional 13 (overall prevalence = 29/121, or 24%). Thickening of the gallbladder wall without stones was demonstrated in 20 patients. Gallbladder abnormalities occur more often in patients with primary sclerosing cholangitis than is generally believed, and include a variety of neoplastic and inflammatory entities

    Gallbladder cancers (GBC) are characterized by rapid progression, early metastasis, and poor prognosis; the molecular mechanisms of the various signaling pathways involved should be elucidated to develop effective therapies. Survivin, an apoptosis inhibitor protein expressed in the G2/M phase of the cell cycle, plays a role in cell division and affects both cell survival and proliferation. Survivin has been investigated in many types of cancer, and this study aims to examine the relationship of survivin expression in gallbladder cancer patients with clinicopathological features and prognosis. We evaluated demographic characteristics (age, gender), tumor characteristics (histopathological type, differentiation, perineural, and lymphovascular invasion; serosal invasion, surgical margin positivity and lymphocytic response), and Survivin expression immunohistochemically, and we analysed the relationship between these characteristics and prognosis in 47 gallbladder carcinoma cases from 2000 to 2011. Immunohistochemically, while survivin expression was observed in 36 cases, it was absent in 11 cases. Follow-up data were obtained from 32 patients. Two (8.7%) of 23 cases with a Survivin-positive tumor were alive at 74th and 35th months, whereas 5 (%55.6) of nine cases with Survivin-negative tumor were alive at 50th, 89th, 124th, 126th, 131th months. Survivin expression was correlated with short survival (p = 0.043), and the univariate analysis showed that reduced overall survival was associated with age (p = 0.043), male gender (p = 0.038), infiltrative pattern (p = 0.019), lymphovascular invasion (p = 0.004), perineural invasion (p = 0.009), serosal invasion (p = 0.027), ulcer (p = 0.033), and surgical margin positivity (p = 0.022). Despite the low number of patients in our study, the analysis results suggest that survivin positivity might actually be a significant prognostic factor. This finding could be a reference point for targeted treatment studies. However, further

    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.

  13. 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

    High-dose-rate intraluminal irradiation with a {sup 60}Co remote afterloading system, using our newly developed applicator, was performed in 15 cases of advanced biliary tract cancer (2 gallbladder cancers, 13 cholangiocarcinomas). The applicator which was thin with an outer diameter of 14 Fr had a double lumen which included a small lumen for a guide wire for easy exchange to a drainage tube. Therefore, the irradiation procedure could be easily finished in a short time within little distress to the patient. The tumor marker CA1 19-9 was useful in assessing the therapeutic effect and follow-up observation after treatment. The average tube-free period and survival time were 5.9 months and 8.3 months, respectively. Histopathological examination of the cases autopsied showed that the combination of intraluminal (30 Gy) and external (30 Gy) irradiation offered good local control of the cancer that was within 1 cm from the source. Cholangiocarcinoma with relatively short length of obstruction, stage III or stage IV when the cancer infiltration was localized around the bile duct, achieved a comparatively long survival time. It was suggested that the combined use of high-dose-rate intraluminal radiotherapy, with precisely delivered radical radiation to tumors localized in the bile duct wall, and external radiotherapy delivered as additional radiation to the surrounding bile duct would provide radiotherapeutic advantage and contribute to survival after treatment for advanced biliary tract cancer.

    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.

    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
