    The effect of the selective antimuscarinic agent, pirenzepine, on gallbladder function was studied in six healthy volunteers, using /sup 99m/Tc HIDA (N-(2,6-diethylthenyl) carbamoylmethyl iminodiacetic acid) hepatobiliary scanning. Pirenzepine, in doses that inhibit gastric acid secretion, did not alter gallbladder emptying responses to sham feeding stimulation or to a test meal.

    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

    We studied gallbladder bile flow before, during, and after cholesterol gallstone formation in the prairie dog using infusion cholescintigraphy with /sup 99m/Tc-diethyl iminodiacetic acid. In 18 fasting animals partitioning of bile between gallbladder and intestine was determined every 15 min for 140 min, and gallbladder response to cholecystokinin (5 U/kg X h) was calculated from the gallbladder ejection fraction. Ten prairie dogs were then placed on a 0.4% cholesterol diet and 8 on a regular diet, and the studies were repeated 1, 2, and 6 wk later. The proportion of hepatic bile that entered the gallbladder relative to the intestine varied from one 15-min period to the next, and averaged 28.2% +/- 5.1% at 140 min. Partial spontaneous gallbladder emptying (ejection fraction 11.5% +/- 5.6%) was intermittently observed. Neither the number nor the ejection fraction of spontaneous gallbladder contractions changed during gallstone formation. By contrast, the percent of gallbladder emptying in response to cholecystokinin decreased from 72.1% +/- 5% to 25.9% +/- 9.3% (p less than 0.025) in the first week and was 14.3% +/- 5.5% at 6 wk (p less than 0.01 from prediet values, not significant from first week). Gallbladder filling decreased from 28.2% +/- 5.1% to 6.7% +/- 3% (p less than 0.01), but this change was only observed after 6 wk, when gallstones had formed. This study shows that bile flow into the gallbladder during fasting is not constant; the gallbladder contracts intermittently; gallbladder emptying in response to exogenous cholecystokinin is altered very early during gallstone formation; and gallbladder filling remains unaffected until later stages, when gallstones have formed.

    Chemical ablation of the gallbladder is effective in patients at high risk of complications after surgery. Percutaneous gallbladder drainage is an effective treatment for cholecystitis; however, when the drain tube cannot be removed because of recurrent symptoms, retaining it can cause problems. An 82-year-old woman presented with cholecystitis and cholangitis caused by biliary stent occlusion and suspected tumor invasion of the cystic duct. We present successful chemical ablation of the gallbladder using pure alcohol, through a percutaneous gallbladder drainage tube, in a patient who developed intractable cholecystitis with obstruction of the cystic duct after receiving a biliary stent. Our results suggest that chemical ablation therapy is an effective alternative to surgical therapy for intractable cholecystitis. PMID:19399941

    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.

    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.

    Gallbladder emptying was induced in female albino mice by single oral administrations of 30% lyophylized egg yolk suspension. Mice were killed 15 min later, their gallbladders removed and then weighed. Gallbladder emptying was assessed by comparing weights from control and egg yolk administered mice. The ability of the antispasmodic drugs atropine, N-butylscopolamine, papaverine, trimebutine, dicyclomine, and rociverine to delay gallbladder emptying was determined by administering them either intraperitoneally or orally 7.5 or 15 min prior to egg yolk.

    The management of patients with symptoms consistent with biliary tract disease who do not have gallstones is difficult. We retrospectively reviewed the charts of 18 patients who underwent cholecystokinin cholescintigraphy at our institution to determine if this procedure was reliable in identifying patients who would benefit from cholecystectomy. All patients underwent biliary screening, and a gallbladder ejection fraction of less than or equal to 35% was considered abnormal. None of the patients had evidence of gallstones by ultrasound. There were 11 patients with abnormal ejection fractions. All 11 patients (100%) had "classic" biliary colic and underwent cholecystectomy. The pathologic diagnosis was chronic cholecystitis in every patient. All patients had complete relief of their symptoms postoperatively with a mean follow-up of 10 months. There were six patients with normal ejection fractions. Only one patient in this group had "classic" biliary colic. This patient had a gallbladder ejection fraction of 38% and endoscopic evidence of gastritis. This patient remains symptomatic despite H2 blockade. The remaining five patients had nonspecific right upper quadrant or epigastric pain. These patients had endoscopic evidence of gastritis, and symptoms were relieved with H2 blockade. The remaining patient had an indeterminate scan due to radioactivity in the duodenum overlying the gallbladder and was excluded from this analysis. Cholecystokinin cholescintigraphy is a useful test in identifying those patients with biliary dyskinesia or acalculous cholecystitis who will benefit from cholecystectomy. PMID:8273847

  13. Evaluation and management of functional biliary pain in patients with an intact gallbladder.

    PubMed

    2009-06-01

    The diagnosis and management of suspected functional biliary pain in patients with an intact gallbladder remains contentious. Major issues include the lack of a clear definition of what constitutes biliary pain, a poor understanding of its natural history and pathophysiology, and the all too common scenario of the patient who has persistent pain despite surgical removal of the gallbladder. As a consequence, symptoms alone have generally been considered to be unreliable in the diagnosis of gallbladder dysfunction, and this has led to a search for a reliable test to help confirm a clinical suspicion of gallbladder dysfunction prior to the definitive treatment, cholecystectomy. At present, cholecystokinin-cholescintigraphy with a calculation of the gallbladder ejection fraction is the most commonly used test; however, its utility in predicting symptom outcome after cholecystectomy has been questioned. The use of cholecystokinin-cholescintigraphy to determine the appropriateness for cholecystectomy appears to be most useful when performed using a slow infusion of cholecystokinin in a well-selected patient population. However, for reasons explained herein, consideration of cholecystectomy on the basis of high clinical suspicion after adequate follow-up with trials of pharmacological therapies and exclusion of other disease entities, together with counseling the patient on postoperative expectations, may be a reasonable alternative.

    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

    We investigated the effect of orally administered trimebutine maleate on gastric and gallbladder emptying and on the release of gut peptide, pancreatic polypeptide (PP), and gastrin in humans for 120 min after ingestion of a solid meal. Gastric emptying was measured by a radionuclide technique. Gallbladder emptying was estimated by real-time ultrasonography. The oral administration of 200 mg of trimebutine maleate significantly shortened the lag time in starting gastric emptying (P < 0.05). Considering gallbladder emptying, trimebutine significantly inhibited the fasting emptying induced by neural reflex. Postprandially, there was a tendency toward an accelerated gallbladder emptying in the early phase. Neither the maximal percentage of gallbladder emptying nor the time of peak gallbladder emptying were affected. Trimebutine significantly blunted the post-prandial PP response in the cephalic and gastric phases, reflecting a vagal-cholinergic activity (P < 0.05). The PP response in the intestinal phase was also blunted. Gastrin release was significantly augmented only during the period of fasting after drug administration (P < 0.05). The major effect of trimebutine maleate appears to be a shortening of the lag time at the start of gastric emptying probably via its anticholinergic activity. PMID:8482179

    “Black” pigment gallstones form in sterile gallbladder bile in the presence of excess bilirubin conjugates (“hyperbilirubinbilia”) from ineffective erythropoiesis, hemolysis, or induced enterohepatic cycling (EHC) of unconjugated bilirubin. Impaired gallbladder motility is a less well-studied risk factor. We evaluated the spontaneous occurrence of gallstones in adult germfree (GF) and conventionally housed specific pathogen-free (SPF) Swiss Webster (SW) mice. GF SW mice were more likely to have gallstones than SPF SW mice, with 75% and 23% prevalence, respectively. In GF SW mice, gallstones were observed predominately in heavier, older females. Gallbladders of GF SW mice were markedly enlarged, contained sterile black gallstones composed of calcium bilirubinate and <1% cholesterol, and had low-grade inflammation, edema, and epithelial hyperplasia. Hemograms were normal, but serum cholesterol was elevated in GF compared with SPF SW mice, and serum glucose levels were positively related to increasing age. Aged GF and SPF SW mice had deficits in gallbladder smooth muscle activity. In response to cholecystokinin (CCK), gallbladders of fasted GF SW mice showed impaired emptying (females: 29%; males: 1% emptying), whereas SPF SW females and males emptied 89% and 53% of volume, respectively. Bilirubin secretion rates of GF SW mice were not greater than SPF SW mice, repudiating an induced EHC. Gallstones likely developed in GF SW mice because of gallbladder hypomotility, enabled by features of GF physiology, including decreased intestinal CCK concentration and delayed intestinal transit, as well as an apparent genetic predisposition of the SW stock. GF SW mice may provide a valuable model to study gallbladder stasis as a cause of black pigment gallstones. PMID:25477375

    There is recent evidence that nitric oxide, a soluble gas produced from L-arginine, is released by the smooth muscle cells and neurons of the gastrointestinal tract where it exerts a myorelaxive action. However, little is known about the effects nitric oxide has on gastric and gallbladder motility during the inter- and postprandial phases in man. We therefore investigated the effects 200 mg/kg/hr L-arginine exerts on the gastric and gallbladder motility induced by 2 mg/kg erythromycin or a liquid meal in 21 subjects in a double-blind, placebo-controlled study. Gastric and gallbladder emptying were evaluated by sonography. Fasting antral motility was expressed as antral motility index (MI). In fasting subjects, L-arginine administration determined a threefold increase in plasma nitrite concentrations. Administration of erythromycin caused a significant rise in the antral MI, which was inhibited by L-arginine (P < 0.05). Ingestion of a liquid meal also significantly increased antral MI, but it returned to basal values 90 min after the end of the meal. Although L-arginine administration caused a significant reduction in the antral MI (P < 0.05), it did not inhibit gastric emptying. L-Arginine provoked an approximately 40% increase in basal gallbladder volume, completely blocked erythromycin-induced emptying, and partially, but significantly, prevented the emptying induced by a liquid meal (P < 0.01). Our study suggests that nitric oxide may be implicated in the physiological modulation of gastric and gallbladder motility during the inter- and postprandial phases in man. PMID:7781462

    The objective of the study was to investigate the effects of a single intravenous injection of the somatostatin analog octreotide on hepatic bile secretion and gallbladder emptying with a quantitative scintigraphic technique. Twelve healthy volunteers received, in a double-blind randomized fashion, either octreotide, 100 micrograms intravenously, or placebo. Ten minutes later, [99mTc]PBIDA was administered intravenously (50 microCi/kg) (time = 0) followed, 60 min later, by the ingestion of a standardized fatty meal. In the liver area, the relative decrease per minute of tracer activity from the time of maximal activity to 60 min was significantly lower in the octreotide group (P = 0.02). In the gallbladder area, after the fatty meal, the ratio of tracer activity at 60 and 90 min (A90/A60) was significantly (P = 0.01) higher in the octreotide group. Our study demonstrates that octreotide slows down liver release of the radiopharmaceutical, probably reflecting decreased bile secretion, and inhibits postprandial gallbladder contraction.

    Gallbladder cancer is the fifth most common cancer involving gastrointestinal tract, but it is the most common malignancy of the biliary tract, accounting for 80-95% of biliary tract cancers. This tumor is a highly lethal disease with an overall 5-year survival of less than 5% and mean survival mere than 6 months. An early diagnosis is essential as this malignancy progresses silently with a late diagnosis. The percentage of patients diagnosed to have gallbladder cancer after simple cholecystectomy for presumed gallbladder stone disease is 0.5-1.5%. Patients with preoperative suspicion of gallbladder cancer should not be treated by laparoscopy. Epidemiological studies have identified striking geographic and ethnic disparities—inordinately high occurrence in American Indians, elevated in Southeast Asia, yet quite low elsewhere in the Americas and the world. Environmental triggers play a critical role in eliciting cancer developing in the gallbladder, best exemplified by cholelithiasis and chronic inflammation from biliary tract and parasitic infections. Improved imaging modalities and improved radical aggressive surgical approach in the last decade has improved outcomes and helped prolong survival in patients with gallbladder cancer. The overall 5-year survival for patients with gallbladder cancer who underwent R0 curative resection was from 21% to 69%. In the future, the development of potential diagnostic markers for disease will yield screening opportunities for those at risk either with ethnic susceptibility or known anatomic anomalies of the biliary tract.

    An incomplete picture has emerged of the complex means by which gallbladder motility is controlled under normal and pathophysiological conditions. In the first part of this review an overall account is presented. The mechanisms of cholecystokinin release, its stimulation by dietary factors and peptides elaborated by both pancreas and small intestine are discussed. The inhibition of cholecystokinin release by bile acids and proteases is also described. In the second part attention is focussed on other peptides affecting motility. These include (a) octreotide, effective for treatment of acromegaly, (b) peptide YY, contributing to a "colonic brake', (c) motilin. associated with interdigestive contractions, analogues of which possibly correct gallbladder hypomotility, and (d) substance P and calcitonin gene-related peptide, which facilitate ganglionic transmission after release from extrinsic sensory neurones and alter gallbladder responses to vagal stimulation. The sympathetic nervous system and diabetes mellitus also influence vagal responses. The former, acting presynaptically, may provide a "brake" to prevent vagal overactivity. The latter could cause hypomotility via autonomic neuropathy, although hyperglycaemia, itself, may play a role. The role of nitric oxide, released from neurones also producing vasoactive intestinal peptide is recognized. Both lengthen muscle, the former producing responses without requiring plasma membrane receptors. Gallbladder motility also changes during pregnancy and stone formation. Progesterone and cholesterol can limit G protein actions, thus impairing contractions. Inflammation is associated with abnormal motility. The production of reactive oxygen metabolites, acting directly or releasing prokinetic prostaglandins, may be responsible. It has been proposed that the gastrointestinal tract may be normally in a state of controlled inflammation, primed to react to harmful challenges. PMID:19864732

    Findings on cholescintigraphy in gallbladder carcinoma are described in five patients. Four patients presenting with acute cholecystitis had nonvisualization of the gallbladder with normal hepatoenteric transit time. One of these had a large portal mass and two had liver metastasis as additional findings. The fifth patient was jaundiced, and showed absence of bowel activity compatible with total biliary obstruction. Both the clinical and scintigraphic findings in gallbladder carcinoma are difficult to separate from findings in cholelithiasis and cholecystitis.

    Acute gallbladder perforation is an infrequent, although not uncommon, complication of cholecystitis. It is rarely diagnosed preoperatively and the delay in making the definitive diagnosis usually accounts for the increased incidence of morbidity and mortality associated with this complication.

    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.

    Gallbladder carcinoma is a relatively rare malignant epithelial neoplasm, arising from gallbladder mucosa. It is the fifth most common gastrointestinal malignancy and the most common biliary tract cancer. Early diagnosis remains difficult, because clinical symptoms are sparse and non-specific, often resulting in advanced stage disease at the time of diagnosis. The most common feature of gallbladder carcinoma on different imaging modalities is focal wall thickening, associated with a large eccentric tumor mass. In this case we report the imaging characteristics of gallbladder carcinoma on ultrasound, MDCT and 18F-FDG PET/CT. PMID:25597210

  11. Acute Biliary Septic Shock

    1990-01-01

    Forty-seven cases of biliary tract infection with septic shock are presented. The sepsis was caused by empyema of the gallbladder in 23 cases and by cholangitis in the remainder. Gallstones were most frequently the cause of the sepsis. An appropriate diagnostic description of the syndrome of biliary tract infection and septic shock should therefore include a description of the underlying biliary disease as well as the term acute biliary shock. In this series, emergency surgical management by removal of gallstones and drainage of suppuration was felt to be the most appropriate treatment. There was a high incidence of gallbladder rupture (10.6%) and intrahepatic stones (53.2%). Of the 13 patients who died, 8 might have survived if early operation had been performed after the diagnosis of acute biliary septic shock was established. PMID:2278914

Ultrasound findings suggested multiple stones in gallbladder and per-operatively she was found to have bilobed gallbladder. This case emphasizes the need for complete removal of both gallbladders during initial surgery, as a failure of this may result in recurrence of symptoms and stones and a need for re-exploration.

    Gallbladder cancer, though generally considered rare, is the most common malignancy of the biliary tract, accounting for 80%–95% of biliary tract cancers. An early diagnosis is essential as this malignancy progresses silently with a late diagnosis, often proving fatal. Its carcinogenesis follows a progression through a metaplasia–dysplasia–carcinoma sequence. This comprehensive review focuses on and explores the risks, management, and outcomes for primary gallbladder carcinoma. Epidemiological studies have identified striking geographic and ethnic disparities – inordinately high occurrence in American Indians, elevated in Southeast Asia, yet quite low elsewhere in the Americas and the world. Age, female sex, congenital biliary tract anomalies, and a genetic predisposition represent important risk factors that are immutable. Environmental triggers play a critical role in eliciting cancer developing in the gallbladder, best exemplified by cholelithiasis and chronic inflammation from biliary tract and parasitic infections. Mortality rates closely follow incidence; those countries with the highest prevalence of gallstones experience the greatest mortality from gallbladder cancer. Vague symptoms often delay the diagnosis of gallbladder cancer, contributing to its overall progression and poor outcome. Surgery represents the only potential for cure. Some individuals are fortunate to be incidentally found to have gallbladder cancer at the time of cholecystectomy being performed for cholelithiasis. Such an early diagnosis is imperative as a late presentation connotes advanced staging, nodal involvement, and possible recurrence following attempted resection. Overall mean survival is a mere 6 months, while 5-year survival rate is only 5%. The dismal prognosis, in part, relates to the gallbladder lacking a serosal layer adjacent to the liver, enabling hepatic invasion and metastatic progression. Improved imaging modalities are helping to diagnose patients at an earlier

  15. Measurement of gallbladder motor functions: an overview.

    PubMed

    Jazrawi, R P

    2003-07-01

    Control of gallbladder motor functions involve a constant interplay between several stimulatory and inhibitory hormones and neurotransmitters. Gallbladder response to a stimulus is complicated involving rapid alternation of emptying and refilling during the postprandial period. Conventional methodology is not capable of evaluating both emptying and refilling in a quantitative manner, and hence previous studies have yielded a large variation in results in health and conflicting results in gallstone patients. There is therefore, a need for improved methodology. Postprandial refilling and turnover of bile are important parameters that need to be assessed when addressing gallbladder motor function and its role in the pathogenesis of cholesterol gallstone disease.

    We report a rare case of gallbladder duplication in a young male patient with acute pyocoele in one vesicle and acute cholecystitis with cystadenoma in the other; another unusual feature was the absent or obliterated cystic duct in the proximal vesicle and non-communication with the second vesicle or the biliary system. Ultrasound examination had suggested a septate gallbladder; the diagnosis of dual gallbladder was made per-operatively during separation of the distal moiety which was presumed to be an adherent duodenum initially. Intraoperative cholecystogram confirmed the diagnosis and both gallbladders were removed successfully laparoscopically. A high degree of awareness, detailed preoperative investigations when anomalies are suspected and intraoperative cholangiography are necessary for accurate detailing of the biliary tree to avoid inadvertent damage to the biliary ductal system and overlooking of second or third gallbladder during surgery.

    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

    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.

    The paper presents an experimental study of pathological human bile taken from the gallbladder and bile ducts. The flow dependences were obtained for different types of bile from patients with the same pathology, but of different age and sex. The parameters of the Casson's and Carreau's equations were found for bile samples. Results on the hysteretic bile behavior at loading-unloading tests are also presented, which proved that the pathologic bile is a non-Newtonian thixotropic liquid. The viscosity of the gallbladder bile was shown to be higher compared to the duct bile. It was found that at higher shear stress the pathological bile behaves like Newtonian fluid, which is explained by reorientation of structural components. Moreover, some pathological bile flow in the biliary system CFD simulations were performed. The velocity and pressure distributions as well as flow rates in the biliary segments during the gallbladder refilling and emptying phases are obtained. The results of CFD simulations can be used for surgeons to assess the patient's condition and choose an adequate treatment.

    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 (/sup 14/C)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/sup -1/ x min/sup -1/, immediately followed by 60-min infusions of either lactated Ringer (LR) or synthetic PYY, 10 or 50 ng x kg/sup -1/ x min/sup -1/. When LR was infused after CCK-OP, gallbladder filling increased by 15.4 +/- 10.5% with minimal changes in gallbladder pressure. Infusion of PYY/sub 10/ resulted in a significant increase in gallbladder volume and filling with a significant decrease in intragallbladder pressure. Similar findings were noted with PYY/sub 50/. 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.

    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 <35%), which is a ratio comparable to that in patients undergoing a CCK-HIDA scan for presumed biliary dyskinesia during the same time period (31 [60%] of 53; P = NS, chi-square test) and exceeds the rate of abnormal GBEF reported in healthy volunteers (3%). Six of seven patients with a low preoperative GBEF who underwent repeat evaluation postoperatively had normalization of the GBEF (P < 0.05, paired t-test). In the 12 patients who underwent postoperative CCK-HIDA scanning, there was no association between preservation or division of the 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

    We report a patient with previous biliary symptoms and endoscopic interventions who presented with clinical features suggestive of choledocholithiasis. Open surgical exploration disclosed three gallbladders with copious stones and varying degrees of acute and chronic inflammation. Literature review revealed only 16 previously reported cases. We review the aetiology of triple gallbladder as being due to failure of rudimentary bile ducts to regress during embryological development, as well as the classification scheme of triple gallbladder based on size, location and number. We also discuss the clinical evaluation and appropriate surgical management of this entity, as triple gallbladders can be associated with cholecystitis or carcinoma. PMID:27435847

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

    A prospective study was carried out in 60 patients to determine the efficacy of /sup 99m/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 /sup 99m/Tc-PIPIDA into the intestinal tract. Normal scans were obtained on 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.

    Diseases of the gallbladder are common and costly. The best epidemiological screening method to accurately determine point prevalence of gallstone disease is ultrasonography. Many risk factors for cholesterol gallstone formation are not modifiable such as ethnic background, increasing age, female gender and family history or genetics. Conversely, the modifiable risks for cholesterol gallstones are obesity, rapid weight loss and a sedentary lifestyle. The rising epidemic of obesity and the metabolic syndrome predicts an escalation of cholesterol gallstone frequency. Risk factors for biliary sludge include pregnancy, drugs like ceftiaxone, octreotide and thiazide diuretics, and total parenteral nutrition or fasting. Diseases like cirrhosis, chronic hemolysis and ileal Crohn's disease are risk factors for black pigment stones. Gallstone disease in childhood, once considered rare, has become increasingly recognized with similar risk factors as those in adults, particularly obesity. Gallbladder cancer is uncommon in developed countries. In the U.S., it accounts for only ~ 5,000 cases per year. Elsewhere, high incidence rates occur in North and South American Indians. Other than ethnicity and female gender, additional risk factors for gallbladder cancer include cholelithiasis, advancing age, chronic inflammatory conditions affecting the gallbladder, congenital biliary abnormalities, and diagnostic confusion over gallbladder polyps.

    Background The biliary system is in continuous contact with the complex microbiota of the intestine. Microbial products have recently been proposed as potential triggers for biliary diseases. Methods The aim of this review is to provide a summary of the current knowledge regarding the role of the biliary and intestinal microbiome in biliary inflammatory diseases. Results Previously, it was suggested that the healthy biliary system is a sterile organ, while acute cholangitis and cholecystitis may occur from ascending infections. Although non-inflammatory biliary colonization by certain bacteria such as Salmonella spp. has been already recognized since several decades, human and animal studies indicated only very recently that the gallbladder harbors a complex microbiota also under non-pathologic conditions. Novel findings suggested that – similar to the situation in the intestine – the biliary mucosa features a chemical, mechanical, and immunological barrier, ensuring immunological tolerance against commensals. However, microbial triggers might influence acute and chronic inflammatory disease of the biliary system and the whole liver. Conclusion Although yet undefined, dysbiosis of the biliary or intestinal microbiota rather than a single microorganism may influence disease progression. PMID:26468308

    Cholecystectomy is a common procedure. Abnormalities in the anatomy of the biliary system are common but an abnormal location of the gallbladder is much rarer. Despite frequent pre-operative imaging, the aberrant location of the gallbladder is commonly discovered at surgery. This article presents a case of a patient with the gallbladder located to the left of the falciform ligament in the absence of situs inversus totalis that presented with right upper quadrant pain. A laparoscopic cholecystectomy was performed and it was noted that the cystic duct originated from the right side. The presence of a left sided gall bladder is often associated with various biliary, portal venous and other anomalies that might lead to intra-operative injuries. The spectrum of unusual positions and anatomical gallbladder abnormalities is reviewed in order to facilitate elective and emergent cholecystectomy as well as other hepatobiliary procedures. With proper identification of the anatomy, minimally invasive approaches are still considered safe. PMID:24124340

    An American Hepato-Pancreato-Biliary Association (AHPBA)-sponsored consensus meeting of expert panellists was convened on 15 January 2014 to review current evidence on the management of gallbladder carcinoma in order to establish practice guidelines. In summary, within high incidence areas, the assessment of routine gallbladder specimens should include the microscopic evaluation of a minimum of three sections and the cystic duct margin; specimens with dysplasia or proven cancer should be extensively sampled. Provided the patient is medically fit for surgery, data support the resection of all gallbladder polyps of >1.0 cm in diameter and those with imaging evidence of vascular stalks. The minimum staging evaluation of patients with suspected or proven gallbladder cancer includes contrasted cross-sectional imaging and diagnostic laparoscopy. Adequate lymphadenectomy includes assessment of any suspicious regional nodes, evaluation of the aortocaval nodal basin, and a goal recovery of at least six nodes. Patients with confirmed metastases to N2 nodal stations do not benefit from radical resection and should receive systemic and/or palliative treatments. Primary resection of patients with early T-stage (T1b-2) disease should include en bloc resection of adjacent liver parenchyma. Patients with T1b, T2 or T3 disease that is incidentally identified in a cholecystectomy specimen should undergo re-resection unless this is contraindicated by advanced disease or poor performance status. Re-resection should include complete portal lymphadenectomy and bile duct resection only when needed to achieve a negative margin (R0) resection. Patients with preoperatively staged T3 or T4 N1 disease should be considered for clinical trials of neoadjuvant chemotherapy. Following R0 resection of T2-4 disease in N1 gallbladder cancer, patients should be considered for adjuvant systemic chemotherapy and/or chemoradiotherapy. PMID:26172135

    After malaria, schistosomiasis remains the most important tropical parasitic disease in large parts of the world. Schistosomiasis has recently re-emerged in Southern Europe. Intestinal schistosomiasis is caused by most Schistosoma (S.) spp. pathogenic to humans and leads to chronic inflammation and fibrosis of the colon as well as to liver fibrosis. Gallbladder abnormalities usually occur in patients with advanced hepatic portal fibrosis due to Schistosoma mansoni infection. Occasionally, gallbladder abnormalities have been seen also in children and occurring without associated overt liver abnormalities.The specific S. mansoni-induced gallbladder abnormalities detectable by ultrasound include typical hyperechogenic wall thickening with external gallbladder wall protuberances. The luminal wall surface is smooth. The condition is usually clinically silent although some cases of symptomatic cholecystitis have been described. The ultrasonographic Murphy response is negative. Gallbladder contractility is impaired but sludge and calculi occur rarely. Contrary to other trematodes such as liver flukes, S. mansoni does not obstruct the biliary tract. Advanced gallbladder fibrosis is unlikely to reverse after therapy. PMID:27169865

    BACKGROUND: Incomplete gallbladder removal following open and laparoscopic techniques leads to residual gallbladder stones. The commonest presentation is abdominal pain, dyspepsia and jaundice. We reviewed the literature to report diagnostic modalities, management options and outcomes in patients with residual gallbladder stones after cholecystectomy. MATERIALS AND METHODS: Medline, Google and Cochrane library between 1993 and 2013 were reviewed using search terms residual gallstones, post-cholecystectomy syndrome, retained gallbladder stones, gallbladder remnant, cystic duct remnant and subtotal cholecystectomy. Bibliographical references from selected articles were also analyzed. The parameters that were assessed include demographics, time of detection, clinical presentation, mode of diagnosis, nature of intervention, site of stone, surgical findings, procedure performed, complete stone clearance, sequelae and follow-up. RESULTS: Out of 83 articles that were retrieved between 1993 and 2013, 22 met the inclusion criteria. In most series, primary diagnosis was established by ultrasound/computed tomography scan. Localization of calculi and delineation of biliary tract was performed using magnetic resonance imaging/magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography. In few series, diagnosis was established by endoscopic ultrasound, intraoperative cholangiogram and percutaneous transhepatic cholangiography. Laparoscopic surgery, endoscopic techniques and open surgery were the most common treatment modalities. The most common sites of residual gallstones were gallbladder remnant, cystic duct remnant and common bile duct. CONCLUSION: Residual gallbladder stones following incomplete gallbladder removal is an important sequelae after cholecystectomy. Completion cholecystectomy (open or laparoscopic) is the most common treatment modality reported in the literature for the management of residual gallbladder stones. PMID:26622110

    Novel cell surface-reactive monoclonal antibodies generated against extrahepatic biliary cells were developed for the isolation and characterization of different cell subsets from normal adult human gallbladder. Eleven antigenically distinct gallbladder subpopulations were isolated by fluorescence-activated cell sorting. They were classified into epithelial, mesenchymal, and pancreatobiliary (PDX1+SOX9+) subsets based on gene expression profiling. These antigenically distinct human gallbladder cell subsets could potentially also reflect different functional properties in regards to bile physiology, cell renewal and plasticity. Three of the novel monoclonal antibodies differentially labeled archival sections of primary carcinoma of human gallbladder relative to normal tissue. The novel monoclonal antibodies described herein enable the identification and characterization of antigenically diverse cell subsets within adult human gallbladder and are putative tumor biomarkers.

    Advances in cellular and molecular biology of extrahepatic cholangiocarcinoma and gallbladder adenocarcinoma are providing innovative means for the diagnosis and treatment of biliary tract cancer. Similarly, refinements in noninvasive studies--including helical computed tomography, magnetic resonance cholangiopancreatography, and endoscopic ultrasonography--are enabling more accurate diagnosis, staging, and treatment planning for these tumors. Complete resection remains the only means for cure, and recent reports from major hepatobiliary centers support aggressive wide resection for bile duct and gallbladder cancer. Palliation of malignant strictures has improved with advanced endoscopic techniques, newer polyurethane-covered stents, endoscopic microwave coagulation therapy, and radiofrequency intraluminal endohyperthermia. The preliminary data on such minimally invasive techniques suggest an improvement in quality of life and survival for selected patients. PMID:17031200

    Objectives: To investigate the clinical, pathological, and sonographic characteristics of unexpected gallbladder carcinoma (UGC). Methods: Of 5424 patients who had undergone cholecystectomy from December 2006 to October 2013, 54 patients with primary gallbladder carcinomas confirmed by pathological diagnosis were identified. The patients were divided into two groups: diagnosed before operation (n=34) and UGC groups (n=20), of whom the clinical, pathological, and sonographic characteristics were compared. Results: No significant differences in age, gender, location of lesion, histological type, length of the gallbladder, existence of biliary sludge, and intestinal gas interference between the two groups were found (all P>0.05). The clinical symptoms, laboratory abnormalities, tumor markers, coexisting gallbladder stones, lesion size, lesion type, degree of differentiation, and tumor staging showed statistically significant differences between the two groups (all P<0.05). On ultrasound, the width of the gallbladder, gallbladder wall thickness, vascularity on color Doppler ultrasound, and bile volume in the gallbladder showed significant differences (all P<0.05). Conclusions: UGCs are commonly found at an early stage, often well-differentiated, wall thickened, and are generally accompanied with cholelithiasis. UGCs should be taken into consideration in cases with cholelithiasis or small gallbladder on ultrasound. PMID:26379911

    Gallbladder cancer is the most common biliary tract malignancy with poor prognosis. MicroRNAs (miRNAs) are a class of small, endogenous, non-coding RNAs of 19–23 nucleotides in length, which regulate gene expression at post-transcriptional and translational levels. Several studies have demonstrated aberrant expression of miRNAs in gallbladder cancer tissues. Recent evidences also demonstrated that specific miRNAs are functionally involved in gallbladder cancer development through modulating cell proliferation, apoptosis, migration, invasion and metastasis. In this review, we explore the possibilities of using miRNAs as prognostic, diagnostic markers and therapeutic targets in gallbladder cancer. PMID:26040010

    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. Compared to controls, gallstone patients showed greater amounts of unexchanged cholecystic-to-hepatic bile (11% vs. 1%, p <.001) and most of them showed impaired gallbladder washout efficacy. Utrasonographic values of bile exchanges were similar to those derived from scintigraphic-sonographic studies in comparable groups of subjects. This study provides new ultrasonographic variables, which better express gallbladder bile retention in gallstone patients and strongly discriminate gallstone patients from controls. PMID:11750742

    The new 99mTc biliary scintigraphy agents are highly sensitive and specific in detecting biliary tract disease and use of them is the initial procedure of choice in evaluating patients with suspected acute cholecystitis. Other clinically useful indications are evaluation of biliary kinetics; evaluation of patients with suspected traumatic bile leakage, gallbladder perforation, or postsurgical biliary tract complications; and evaluation of patients with suspected biliary obstruction. In 99mTc we have a simple radiopharmaceutical of low radiation for evaluating congenital abnormalities and neonatal jaundice. In the Orient 99mTc cholescintigraphy is extremely important in evaluating patients with suspected intrahepatic stones. The overall advantages of this technique include availability, safety, simplicity, and accuracy. In addition, it may be performed in those patients who are allergic to iodinated contrast agents.

    AIM: To investigate the effects of gallbladder stones on motor functions of the gallbladder and the dynamics of bile flow in asymptomatic gallstone disease. METHODS: Quantitative hepatobiliary scintigraphy was performed to detect the parameters of gallbladder motor function [gallbladder ejection fraction (GBEF), gallbladder visualization time (GBVT), gallbladder time to peak activity (GBTmax), gallbladder half emptying time (GBT1/2), and transit time of bile to duodenum (TTBD)] in 24 patients with asymptomatic cholelithiasis who were diagnosed incidentally during routine abdominal ultrasonographic examination and 20 healthy subjects with normal gallbladder. RESULTS: Even though there was no significant difference in the clinical and laboratory parameters between the patient and control groups, all parameters of gallbladder function except TTBD were found to differ significantly between the two groups. GBEF in the patient group was decreased (P = 0.000) and GBVT, GBTmax, GBT1/2 in the patient group were longer (P = 0.000, P = 0.015, P = 0.001, respectively). CONCLUSION: Our results showed that even if there were not any clinical and laboratory findings, gallbladder filling and emptying could be impaired in patients with gallstone disease. PMID:19522027

    A 7-year-old, miniature dachshund was referred for examination and treatment of persistent anorexia, deep yellow-coloured urine and leucocytosis. The clinical sign of jaundice, results from a serum biochemistry profile and ultrasonographic images suggested a biliary tract obstruction. A cholecystectomy was performed to remove the obstruction. Histopathological assessment of the resected gallbladder and partial common bile duct indicated diffuse large B-cell lymphoma. Twelve days after the initial operation, a second procedure was performed due to bile leakage into the abdominal cavity. Chemotherapy was administered twice after the second operation but discontinued, because the dog showed adverse effects. The dog is still alive 24 months after the surgery. To the authors' knowledge, this is the first description of canine gallbladder lymphoma. PMID:25311915

    Gallbladder carcinoma is the most common biliary tract tumor and the fifth most common gastrointestinal tract cancer .The prognosis of gallbladder carcinoma is poor and less than 5% of the patients are still alive five years postoperatively. Gallbladder specimens were obtained during surgical operations performed in eleven patients for resection of a gallbladder carcinoma, and during five autopsies (control cases selected among patients who died from for other causes, excluding those suffering from biliary or hepatic diseases). Immunohistochemical characterization and distribution of neurotrophins, with their respective receptors, were analyzed. The actual role played by these neurotrophic factors in the general regulation, vascular permeability, algic responsiveness, release of locally active substances and potential tumorigenesis in the gallbladder and biliary ducts compartment remains controversial. Our study revealed an increased immunohistochemical expression of NGF and TrKA in the epithelium and in the epithelial glands of the gallbladder carcinoma together with an evident immunoreactivity for BDNF in the same neoplastic areas. An evident immunoreactivity for NGF, TrKA and BDNF was observed in control specimens of gallbladder obtained during autopsies, whereas a weak or quite absent immunoreactivity was observed in the same specimens for NT4, TrKC and p75. On the contrary an appreciable immunoreactivity for p75 was observed in the specimens harvested from patients with gallbladder carcinoma.

    Accessory gallbladder is a rare congenital anomaly occurring in 1 in 4000 births, that is not associated with any specific symptoms. Usually this cannot be diagnosed on ultrasonography and hence they are usually not diagnosed preoperatively. Removal of the accessory gallbladder is necessary to avoid recurrence of symptoms. H-type accessory gallbladder is a rare anomaly. Once identified intra-operatively during laparoscopic cholecystectomy, the surgery is usually converted to open. By using the main gallbladder for liver traction and doing a dome down technique for the accessory gallbladder, we were able to perform the double cholecystectomy with intra-operative cholangiogram laparoscopically. Laparoscopic cholecystectomy was performed in 27-year-old male for biliary colic. Prior imaging with computer tomography-scan and ultrasound did not show a duplicated gallbladder. Intraoperatively after ligation of cystic artery and duct an additional structure was seen on its medial aspect. Intraoperative cholangiogram confirmed the patency of intra-hepatic and extra-hepatic biliary ducts. Subsequent dissection around this structure revealed a second gallbladder with cystic duct (H-type). Pathological analysis confirmed the presence of two gallbladders with features of chronic cholecystitis. It is important to use cholangiogram to identify structural anomalies and avoid complications.

    Introduction Gallbladder duplication is a rare congenital anomaly. Recognition of this anomaly and its various types is important since it can complicate a simple hepatobiliary surgical procedure. Presentation of case We report a case of a 42 year old female who presented a 6 year history of intermittent right upper quadrant abdominal pain. Her basic blood investigations including liver function tests were normal. Pre-operative imaging revealed a cystic lesion communicating with biliary tree representing duplicated gallbladder. She subsequently underwent successful laparoscopic cholecystectomy. The operative challenges were more than those anticipated at the usual laparoscopic gallbladder procedures. After six months follow up the patient remained asymptomatic. Discussion Preoperative diagnosis plays a crucial role in planning surgery, and preventing possible biliary injuries or re-operation if accessory gallbladder has been overlooked during initial surgery. Magnetic resonance cholangiopancreatography (MRCP) is the imaging modality of choice for suspected duplicate gallbladder. Laparoscopic cholecystectomy for duplicate gallbladder is a challenging operation and should be performed with meticulous dissection of the cysto-hepatic triangle. Conclusion Gallbladder anomalies should be anticipated in the presence of a cystic lesion reported around the gallbladder. The laparoscopic cholecystectomy remains feasible for intervention and should be done by an experienced laparoscopic surgeon. PMID:27002289

    Thirty-six patients with biliary colic and normal oral cholecystograms, upper gastrointestinal tract roentgenograms, and results of gallbladder ultrasonography underwent sincalide-stimulated biliary excretion scanning. Nineteen of these patients subsequently underwent cholecystectomies. Gallbladder ejection fractions (EFs) ranged from 0% to 88% (mean, 38%) and nine of 19 patients had exact pain reproduction with sincalide. All patients except one (EF, 35%) were cured of their symptoms. However, five patients were also cured who had a normal EF (greater than 50%). Histologically, 11 gallbladders showed chronic cholecystitis and eight were normal. The authors conclude that the sincalide biliary excretion scan is a useful test to study this group of patients. In patients with a decreased EF, cholecystectomy can be recommended with a high probability of symptom relief. In patients with normal EFs, clinical judgment is required, as some of these patients (five of five in this series) may still benefit from operation.

    The assessment of echographic features of biliary atresia was conducted in 65 newborn children ageing up to 3 mo. Their characteristic variants were revealed: the absence or reduction in size of gall-bladder, the presence of hyperechogenic triangular formation in V. portae bifurcation (the symptom of "triangular cicatrix"); the thickening of anterior wall of V. portae right branch. The timely and correct establishment of the diagnosis permits a child to survive and serve the hepatic fibrosis prophylaxis. Echohepatography is a sufficiently trustful method of investigation.

    PubMed Central

    2014-01-01

    Malignancies of the biliary tract include cholangiocarcinoma, gallbladder cancers and carcinoma of the ampulla of Vater. Biliary tract adenocarcinomas are the second most common primary hepatobiliary cancer. Due to their slow growing nature, non-specific and late symptomatology, these malignancies are often diagnosed in advanced stages with poor prognosis. Apart from incidental discovery of gall bladder carcinoma upon cholecystectomy, early stage biliary tract cancers are now detected with computed tomography (CT) and magnetic resonance imaging (MRI) with magnetic resonance cholangiopancreatography (MRCP). Accurate characterization and staging of these indolent cancers will determine outcome as majority of the patients’ are inoperable at the time of presentation. Ultrasound is useful for initial evaluation of the biliary tract and gallbladder masses and in determining the next suitable modality for further evaluation. Multimodality imaging plays an integral role in the management of the biliary tract malignancies. The imaging techniques most useful are MRI with MRCP, endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound (EUS) and positron emission tomography (PET). In this review we will discuss epidemiology and the role of imaging in detection, characterization and management of the biliary tract malignancies under the three broad categories of cholangiocarcinomas (intra- and extrahepatic), gallbladder cancers and ampullary carcinomas.

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

    A 47 years old female with congenital absence of the gallbladder and the cystic duct was presented. The diagnosis was confirmed by exploratory laparatomy, common duct tube cholangiography, and ultrasonography. Most of the operated cases of congenital absence of the gallbladder are symptomatic, and they get relief after common duct exploration. Although the biliary tree is normal on inspection at exploration, it is believed that the symptomatology may have root in congenital abnormality of function. Treatment of the agenesis of the gallbladder as described in earlier days has been discussed. In the present situation, specially in a country like Ethiopia where long time care of internal drains is a worrisome problem, and a major point for concern, the author believes choledocho-enteric anastomosis to be a good solution.

    Early surgery for biliary pancreatitis has resulted in a need for an accurate method of gallstone detection in acute pancreatitis. Fifty patients with acute pancreatitis were studied prospectively to assess the diagnostic value of Radionuclide Biliary Scanning (RBS) performed within 72 hours of an attack. To assess the general accuracy of RBS a further 154 patients with suspected acute cholecystitis or biliary colic were similarly studied. There were 34 patients with biliary pancreatitis and 18 (53%) had a positive scan (no gallbladder seen). There were 16 patients with non-biliary pancreatitis and 5 (31%) had a positive scan. All 51 patients with acute cholecystitis had a positive scan, as did 82% of the 51 patients with biliary colic. There were 52 patients with no biliary or pancreatic disease and none of these had a positive scan. RBS is highly accurate in confirming a diagnosis of acute cholecystitis or biliary colic. However, it cannot be relied on to differentiate between biliary and non-biliary pancreatitis and should certainly not be used as the basis for biliary surgery in these patients. PMID:6859781

    A case of gallbladder perforation is presented in which a small bile leak was demonstrated by cholescintigraphy while the patient was receiving meperidine, but not after meperidine was discontinued. The scintigrams obtained during meperidine therapy also showed a pattern of bile-duct obstruction. It is suggested that increased biliary pressure secondary to meperidine admininstration permitted visualization of the leak. Use of narcotic drugs may be a useful pharmocologic intervention in cases of peritonitis due to small obscure bile leaks.

    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.

    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

The image presentations on US, CT and angiography were also reviewed. RESULTS: Left-sided gallbladder was diagnosed in nine patients. The associated abnormalities on CT imaging included portal vein anomalies, absence of umbilical portion of the portal vein in the left lobe of the liver, club-shaped portal vein in the right lobe of the liver, and difficulty in identifying segment IV. Angiography in six of nine patients demonstrated abnormal portal venous system (trifurcation type in four of six patients). The main hepatic arteries followed the portal veins in all six patients. The segment IV artery was identified in four of six patients using angiography, although segment IV was difficult to define on CT imaging. Hepatectomy was performed in three patients with concomitant liver tumor and the diagnosis of left-sided gallbladder was confirmed intraoperatively. CONCLUSION: Left-sided gallbladder is an important clinical entity in hepatectomy due to its associated portal venous and biliary anomalies. It should be considered in US, CT and angiography images that demonstrate no definite segment IV, absence of umbilical portion of the portal vein in the left lobe, and club-shaped right anterior portal vein.

  10. Nonvisualized gallbladder on oral cholecystography: implications for lithotripsy.

    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.

    Laparoscopic cholecystectomy is widely accepted nowadays as the gold standard in the treatment of cholelithiasis. This new technique was initially associated with a significant increase in morbidity, and in particular in iatrogenic biliary injuries and arterial haemorrhages, perhaps due to a lack of knowledge of the "laparoscopic anatomy" of the gallbladder pedicle. In this technique the anatomical structures are viewed on a two-dimensional video monitor, and the dissection is performed with long instruments without manual sensitivity. Therefore, the laparoscopic surgeon has to deal with new anatomical views and must be aware of the possible arterial and biliary variants. In this review we describe our technique of laparoscopic cholecystectomy, with particular reference to manoeuvres useful for identifying the various anatomical structures at the gallbladder hilum. In our opinion, it is mandatory to avoid cutting any duct if its identity has yet to be established. For this reason, we pay great attention to the anatomical dissection of Calot's triangle, in order to accurately identify the cystic duct and the cystic artery and any other vascular or biliary structures. Routine intraoperative cholangiography may be useful for identifying the biliary anatomy. When in doubt, the surgeon should not hesitate to convert the procedure to open surgery. PMID:15287636

    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.

    Portal biliopathy is defined as abnormalities in the extra- and intrahepatic ducts and gallbladder of patients with portal hypertension. This condition is associated with extrahepatic venous obstruction and dilatation of the venous plexus of the common bile duct, resulting in mural irregularities and compression of the biliary tree. Most patients with portal biliopathy remain asymptomatic, but approximately 10% of them advance to symptomatic abdominal pain, jaundice, and fever. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography are currently used as diagnostic tools because they are noninvasive and can be used to assess the regularity, length, and degree of bile duct narrowing. Management of portal biliopathy is aimed at biliary decompression and reducing the portal pressure. Portal biliopathy has rarely been reported in Korea. We present a symptomatic case of portal biliopathy that was complicated by cholangitis and successfully treated with biliary endoscopic procedures. PMID:27044769

    Introduction Biliary colic is a common clinical presentation, with the majority of cases being related to gallstone disease. However, rarely, patients may present with biliary symptoms without evidence of gallbladder stones – referred to as acalculous gallstone disease. This case report details a rare case of chronic biliary colic associated with ketamine abuse. Case presentation A 24-year-old Caucasian female presented to the emergency department with a history of intermittent right upper quadrant pain associated with nausea and malaise. She had experienced bouts of similar symptoms three times a year for the past 4 years. Various investigations had been conducted during her multiple admissions, which showed possible dilatation of the common bile duct, with no evidence of gallstones. Conclusion Patients can present with a dilated common bile duct and an acalculous cholecystitis. This requires considerable investigation, with an emphasis on drug history, especially with the current rise of recreational hallucinogenic drug abuse. PMID:27330331

    The gallbladder is affected by a large number of congenital anomalies, which may affect its location, number, size, or form. Some of these malformations are very rare and may lead to misdiagnosis. An ectopic gallbladder can be misinterpreted as agenesis of the organ or as a cystic hepatic mass when intrahepatic. Given the frequency and the wide acceptance of the ultrasonographic examination of the biliary tract, radiologists should be aware of these malformations. In some cases, ultrasonographic diagnosis can be difficult. However, the use of Computed Tomography can elucidate such cases. We present the case of a patient whose gallbladder had two combined malformations but caused no symptoms. Namely, the patient had a transverse ectopic gallbladder combined with a “Phrygian cap” deformity. The incidence of ectopic locations of the gallbladder is 0.1–0.7%, whereas the “Phrygian cap” deformity can be found in 4% of patients. There is no other cases with combination of these two entities reported in the literature. Ultrasonographic and CT findings are presented and aspects of this malformation are discussed. The clinical significance of ectopic gallbladder is also emphasized because it may alter the clinical presentation of biliary tract diseases and pose technical problems during surgery. PMID:24716073

    AIM: To determine the risk factors for gallstone-related biliary events. METHODS: This retrospective cohort study evaluated magnetic resonance cholangiopancreatography images from 141 symptomatic and 39 asymptomatic gallstone patients who presented at a single tertiary hospital between January 2005 and December 2012. RESULTS: Logistic regression analysis showed significant differences between symptomatic and asymptomatic patients with gallstones in relation to the number of gallstones, the angle between the long axis of the gallbladder and the cystic duct, and the cystic duct diameter. Multivariate analysis showed that the number of gallstones (OR = 1.27, 95%CI: 1.03-1.57; P = 0.026), the angle between the long axis of the gallbladder and the cystic duct (OR = 1.02, 95%CI: 1.00-1.03; P = 0.015), and the diameter of the cystic duct (OR = 0.819, 95%CI: 0.69-0.97; P = 0.018) were significantly associated with biliary events. The incidence of biliary events was significantly elevated in patients who had the presence of more than two gallstones, an angle of > 92° between the gallbladder and the cystic duct, and a cystic duct diameter < 6 mm. CONCLUSION: These findings will help guide the treatment of patients with asymptomatic gallstones. Clinicians should closely monitor patients with asymptomatic gallstones who exhibit these characteristics. PMID:25574102

    The primary malignancies of the biliary tract, cholangiocarcinoma and gallbladder cancer, often present at an advanced stage and are marginally sensitive to radiation and chemotherapy. Accumulating evidence indicates that molecularly targeted agents may provide new hope for improving treatment response in biliary tract carcinoma (BTC). In this article, we provide a critical review of the pathogenesis and genetic abnormalities of biliary tract neoplasms, in addition to discussing the current and emerging targeted therapeutics in BTC. Genetic studies of biliary tumors have identified the growth factors and receptors as well as their downstream signaling pathways that control the growth and survival of biliary epithelia. Target-specific monoclonal antibodies and small molecules inhibitors directed against the signaling pathways that drive BTC growth and invasion have been developed. Numerous clinical trials designed to test these agents as either monotherapy or in combination with conventional chemotherapy have been completed or are currently underway. Research focusing on understanding the molecular basis of biliary tumorigenesis will continue to identify for targeted therapy the key mutations that drive growth and invasion of biliary neoplasms. Additional strategies that have emerged for treating this malignant disease include targeting the epigenetic alterations of BTC and immunotherapy. By integrating targeted therapy with molecular profiles of biliary tumor, we hope to provide precision treatment for patients with malignant diseases of the biliary tract. PMID:26819503

  2. CAV1 Prevents Gallbladder Cholesterol Crystallization by Regulating Biosynthesis and Transport of Bile Salts.

    PubMed

    2016-09-01

    Cholesterol gallstone disease (CGD) is a hepatobiliary disorder which results from a biochemical imbalance in the gallbladder bile. Here we show that loss of CAV1 sensitized mice to lithogenic diet-induced gallbladder cholesterol crystallization, which was associated with dysregulation of several hepatic transporters that efflux cholesterol, phospholipids, and bile salts. The combined effect of increased biliary cholesterol concentration and decreased biliary bile salt secretion in CAV1(-/-) mice led to an increased cholesterol saturation index and the formation of cholesterol crystals. At the signaling level, the ERK/AP-1 pathway seems to mediate the effects of CAV1 on biliary BA homeostasis and might be developed as a therapeutic target for CGD. We propose that CAV1 is an anti-lithogenic factor and that the CAV1(-/-) mice may offer a convenient CGD model to develop therapeutic interventions for this disease. J. Cell.

    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

    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.

    Isolated agenesis of the gallbladder is a rare anomaly, often asymptomatic. However, one patient out of four presented with right upper abdominal pain, nausea, and fatty food intolerance. The condition is frequently mistaken with an excluded or sclero-atrophic gallbladder, regardless of the imaging modality used. Consequently, AG often leads to unnecessary and potentially dangerous laparoscopic surgery as described in a few case reports over the last 10 years. The aim of this study is to clarify the diagnostic and therapeutic approach of this unusual pathology. Two cases seen in our institutions were retrospectively reviewed, together with a review of the American and European literature. During laparoscopy, the absence of normal anatomical structures and the impossibility of pulling on the gallbladder to expose and dissect the triangle of Callot increases the risk of iatrogenic injury to biliary or portal structures. Depending on the experiment of the surgeon in laparoscopic procedure, this has to be taken into account to decide a conversion to laparotomy. A high index of suspicion is necessary when interpreting the radiological images. In case of doubt, a MRI-cholangiography is mandatory. Because of possible inherited transmission, relatives with a history of biliary symptoms should be investigated. PMID:16273658

    Gallbladder cancer (GBC) is an uncommon disease in the majority of the world despite being the most common and aggressive malignancy of the biliary tree. Early diagnosis is essential for improved prognosis; however, indolent and nonspecific clinical presentations with a paucity of pathognomonic/predictive radiological features often preclude accurate identification of GBC at an early stage. As such, GBC remains a highly lethal disease, with only 10% of all patients presenting at a stage amenable to surgical resection. Among this select population, continued improvements in survival during the 21st century are attributable to aggressive radical surgery with improved surgical techniques. This paper reviews the current available literature of the 21st century on PubMed and Medline to provide a detailed summary of the epidemiology and risk factors, pathogenesis, clinical presentation, radiology, pathology, management, and prognosis of GBC.

    1975-01-01

    This review brings the total number of biliary cysts reported in the world literature to 955. Eighty-one per cent of patients are females and 61% were discovered before age ten. The classical triad of right upper quadrant pain, right upper quandrant mass, and juandice is present in 38% of cases. The duration of symptoms prior to diagnosis ranged from less than one week to more than 40 years. The etiology is multifaceted and evidence of the existence of both acquired and congenital cysts is presented. The most useful diagnostic tool is fiberoptic endoscopy with retrograde contrast injection of the common bile duct and pancreatic duct. The incidence of biliary carcinoma in patients with biliary cysts is found to be 2.5%; 24 cases have been reported. Considerable controversy has existed concerning the best operative procedure for biliary cysts; no treatment or medical treatment yielding a 97% mortality rate. In an analysis of 235 patients presented since 1968 with an average followup of 5.2 years, the best procedure appears to be excision with either choledochocholedocostomy or Roux-en-Y hepaticojejunostomy. The operative mortality for all procedures is now 3 to 4%. PMID:1103760

    Biliary atresia (BA) is a rare disease characterised by a biliary obstruction of unknown origin that presents in the neonatal period. It is the most frequent surgical cause of cholestatic jaundice in this age group. BA occurs in approximately 1/18,000 live births in Western Europe. In the world, the reported incidence varies from 5/100,000 to 32/100,000 live births, and is highest in Asia and the Pacific region. Females are affected slightly more often than males. The common histopathological picture is one of inflammatory damage to the intra- and extrahepatic bile ducts with sclerosis and narrowing or even obliteration of the biliary tree. Untreated, this condition leads to cirrhosis and death within the first years of life. BA is not known to be a hereditary condition. No primary medical treatment is relevant for the management of BA. Once BA suspected, surgical intervention (Kasai portoenterostomy) should be performed as soon as possible as operations performed early in life is more likely to be successful. Liver transplantation may be needed later if the Kasai operation fails to restore the biliary flow or if cirrhotic complications occur. At present, approximately 90% of BA patients survive and the majority have normal quality of life. PMID:16872500

    The files of patients with acute cholecystitis from two large university hospitals from the years 1978-1985 were employed to find the cases with acute gallbladder perforation for this study. Only those patients (n = 9) were selected for the analysis of sonographic signs of acute gallbladder perforation who had less than 48 hours of symptoms before sonography, and were operated upon within 24 hours of the sonography. Patients (n = 10) with non-complicated acute cholecystitis and identical in regard to the duration of the symptoms and the timing of the sonography and the operation formed a control group. The sonographic findings in patients with gallbladder perforation were pericholecystic fluid collections, free peritoneal fluid, disappearance of the gallbladder wall echoes, focal highly echogenic areas with acoustic shadows in the gallbladder, and an inhomogeneous, generally echo-poor gallbladder wall.

    Various drugs and medications that inhibit or stimulate gallbladder contraction and basal tone in humans are described. Active gallbladder contraction may be achieved using synthetic hormones such as cholecystokinin, caerulein and motilin, cholinomimetic drugs such as bethanecol, prostigmine, and erythromycin due to its motilin-like effect. Furthermore, cisapride and cholestyramine, may have some excitatory activity on the gallbladder muscle. Intravenous amino acids also induce gallbladder contraction through the release of cholecystokinin. Inhibition of gallbladder contraction induced by a meal, or reduction of the basal fasting tone may be achieved by using atropine and other cholinergics, and by inhibitory hormones such as somatostatin, the nitric acid releaser arginine, the calcium channel antagonist nifedipine, and progesterone. Other drugs such as trimebutine, loperamide and ondansetron may negatively affect gallbladder contraction. PMID:12974504

    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

    We herein report a case of gallbladder carcinoma associated with occult pancreatobiliary reflux (PR) in the absence of pancreatobiliary maljunction. A 67-year-old woman was referred to our hospital for the evaluation and treatment of a gallbladder tumor. Ultrasonography and computed tomography showed a nodular lesion in the fundus of the gallbladder, indicating the possibility of a gallbladder carcinoma. Endoscopic ultrasonography showed the nodular tumor and thickness of the surrounding epithelium. Endoscopic retrograde cholangiopancreatography revealed a normal pancreaticobiliary junction without the common channel and a slight dilatation of the common bile duct (15 mm in diameter). An open cholecystectomy and partial resection of the liver bed of the gallbladder with regional lymphadenectomy was performed. A C-tube was inserted from the cut end of the cystic duct into the common bile duct to prevent bile stasis. Biliary amylase and lipase levels sampled in the gallbladder were 2604 IU/l and 775 IU/l, respectively. Biliary amylase level in the bile collected from the C-tube in the common bile duct was 119 550 IU/l on postoperative day (POD) 6 and 22 265 IU/l on POD 12. These observations suggested that PR was present in this patient. The histopathological findings of the resected specimen showed a well-differentiated adenocarcinoma of the gallbladder with invasion to the muscle layer and no metastasis of the resected lymph nodes. A high index of nuclear staining for MIB-I in the cancer cells (about 10%) was exhibited, and a few cells in the normal epithelium also stained positive. PMID:17909727

    Conventional ultrasound (US) is the first-line imaging investigation for biliary diseases. However, it is lack of the ability to depict the microcirculation of some lesions which may lead to failure in diagnosis for some biliary diseases. The use of contrast-enhanced US (CEUS) has reached the field of bile duct disease in recent years and promising results have been achieved. In this review, the methodology, image interpretation, enhancement pattern, clinical usefulness, and indications for CEUS in the biliary system are summarized. CEUS may be indicated in the biliary system under the following circumstances: (1) Where there is a need to make a characterization of intrahepatic cholangiocarcinoma (ICC); (2) For differentiation diagnosis between ICC and other tumors (i.e. hepatocellular carcinoma or liver metastasis) or infectious diseases; (3) For differentiation diagnosis between biliary cystadenoma and biliary cystadenocarcinoma; (4) To detect malignant change in Caroli's disease; (5) To depict the extent of Klatskin's tumor with greater clarity; (6) To make a distinction between gallbladder cholesterol polyp, adenoma and polypoid cancer; (7) To make a distinction between chronic cholecystitis with thickened wall and gallbladder cancer; (8) For differentiation diagnosis between motionless sludge and gallbladder cancer; (9) For differentiation diagnosis between common bile duct cancer and sludge or stone without acoustic shadowing; and (10) In patients who are suspected of having a drop of their percutaneous transhepatic cholangiodrainage tube, US contrast agent can be administered to through the tube detect the site of the tube.

    Hepatic infarction is known as a rare disease entity in nontransplant patients. Although a few cases of hepatic infarction have been reported to be linked with invasive procedures, trauma, and hypercoagulability, a case of spontaneous hepatic infarction in a nontransplanted patient has hardly ever been reported. However, many clinical situations of patients with cancer, in particular biliary cancer, can predispose nontransplant patients to hepatic infarction. Besides, the clinical outcome of hepatic infarction in patients with cancer can be worse than in patients with other etiologies. As for treatment, anticoagulation treatment is usually recommended. However, because of its multifactorial etiology and combined complications, treatment of hepatic infarction is difficult and not simple. Herein, we report a case of fatal hepatic infarction that occurred spontaneously during the course of treatment in a patient with gallbladder cancer. Hepatic infarction should be considered as a possible fatal complication in patients during treatment of biliary malignancies. PMID:27462232

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.

    A laparoscopic-guided technique of percutaneous gallstone fragmentation/removal has been developed in the pig. The procedure entails the creation of a percutaneous access cholecystostomy. The access tract can be safely dilated after 7 days to F16, thereby allowing the introduction of both the Olympus flexible and the Berci-Shore rigid choledochoscopes. Following endoscopic occlusion of the cystic duct by a biliary balloon catheter, stone fragmentation can be conducted under direct visual control. In this particular study, electrohydraulic lithotripsy was performed of human cholesterol and bile-pigment stones inserted into the gallbladder of 16 pigs. The gallstone debris resulting from lithotripsy was then washed out with saline. Larger residual fragments could easily be extracted with the Dormia basket under visual guidance. There was a significant positive correlation between stone size (r = 0.98) and weight (r = 0.96) and the number of pulses needed to achieve satisfactory stone fragmentation. The gross composition of the stones (predominantly cholesterol or pigment) did not influence the number of pulses required. Electrohydraulic lithotripsy caused an explosion effect (the fragments hit the gallbladder wall), causing submucosal haematoma formation. This, however, was not followed by any untoward effect until sacrifice of the animals 10-16 weeks later. Electrohydraulic shocks delivered to the gallbladder wall itself resulted in larger haematoma formation and breach of the gallbladder mucosa with active bleeding into the gallbladder lumen, but again no instance of gallbladder perforation was encountered.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2530642

    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

    We encountered a case of hepatic hilar cholangiocarcinoma resulting in cholecystoduodenal fistula after insertion of self-expandable metallic biliary stents (EMBSs). To our knowledge, there has been no report of cholecystoduodenal fistula after insertion of EMBSs. This case suggests that immediate gallbladder decompression may be necessary if acute cholecystitis occurs after insertion of EMBSs.

    Chronic acalculous cholecystitis represents 5 to 20 per cent of electively treated diseases of the gallbladder. A 70 per cent success rate in relieving these patients of chronic pain was reported when surgical treatment was recommended based on symptoms alone. The cholecystokinin ejection fraction, which is a quantitative measure of emptying of the gallbladder, was 95 per cent accurate in predicting which patients would be relieved of symptoms by surgical treatment. In this study, we report our consecutive experience during a 20 month period with 83 patients.

    Background 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. Methods 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). Results 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%. Conclusions 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

    AIM: To determine the optimal method of endoscopic preoperative biliary drainage for malignant distal biliary obstruction. METHODS: Multicenter retrospective study was conducted in patients who underwent plastic stent (PS) or nasobiliary catheter (NBC) placement for resectable malignant distal biliary obstruction followed by surgery between January 2010 and March 2012. Procedure-related adverse events, stent/catheter dysfunction (occlusion or migration of PS/NBC, development of cholangitis, or other conditions that required repeat endoscopic biliary intervention), and jaundice resolution (bilirubin level < 3.0 mg/dL) were evaluated. Cumulative incidence of jaundice resolution and dysfunction of PS/NBC were estimated using competing risk analysis. Patient characteristics and preoperative biliary drainage were also evaluated for association with the time to jaundice resolution and PS/NBC dysfunction using competing risk regression analysis. RESULTS: In total, 419 patients were included in the study (PS, 253 and NBC, 166). Primary cancers included pancreatic cancer in 194 patients (46%), bile duct cancer in 172 (41%), gallbladder cancer in three (1%), and ampullary cancer in 50 (12%). The median serum total bilirubin was 7.8 mg/dL and 324 patients (77%) had ≥ 3.0 mg/dL. During the median time to surgery of 29 d [interquartile range (IQR), 30-39 d]. PS/NBC dysfunction rate was 35% for PS and 18% for NBC [Subdistribution hazard ratio (SHR) = 4.76; 95%CI: 2.44-10.0, P < 0.001]; the pig-tailed tip was a risk factor for PS dysfunction. Jaundice resolution was achieved in 85% of patients and did not depend on the drainage method (PS or NBC). CONCLUSION: PS has insufficient patency for preoperative biliary drainage. Given the drawbacks of external drainage via NBC, an alternative method of internal drainage should be explored. PMID:27076764

    Gallstone disease is common: >700,000 cholecystectomies and costs of approximately 6.5 billion dollars annually in the U.S. The burden of disease is epidemic in American Indians (60-70%); a corresponding decrease occurs in Hispanics of mixed Indian origin. Ten to fifteen per cent of white adults in developed countries harbour gallstones. Frequency is further reduced in Black Americans, East Asia and sub-Saharan Africa. In developed countries, cholesterol gallstones predominate; 15% are black pigment. East Asians develop brown pigment stones in bile ducts, associated with biliary infection or parasites, or in intrahepatic ducts (hepatolithiasis). Certain risk factors for gallstones are immutable: female gender, increasing age and ethnicity/family (genetic traits). Others are modifiable: obesity, the metabolic syndrome, rapid weight loss, certain diseases (cirrhosis, Crohn's disease) and gallbladder stasis (from spinal cord injury or drugs like somatostatin). The only established dietary risk is a high caloric intake. Protective factors include diets containing fibre, vegetable protein, nuts, calcium, vitamin C, coffee and alcohol, plus physical activity.

    Increasing survival rates for carcinoma of the biliary tree could reflect the selection of patients for referral to a specialist centre as well as modern improvements in diagnosis and treatment. To determine the true incidence and outcome of biliary cancer, the records of 243 unselected Bristol patients were reviewed retrospectively over a 15-year period. Mean age was 64 years. Gallstones were associated in 38% of cases. Sixty-nine of 87 patients with gallbladder carcinoma were submitted to laparotomy. The operative (30-day) mortality rate was 56% and the one-year survival rate was 7%; one patient with an unexpected carcinoma is alive 7 years after cholecystectomy (1% five-year survival rate). Among 31 patients with carcinoma of the ampulla the operative mortality rate was 27%; one-year and five-year survival rates were 46% and 15%. Bile duct cancers (n = 125) arose proximal to the entry of the cystic duct (n = 63), distal to that point (n = 46) or diffusely (n = 16). For proximal cholangiocarcinoma the operative mortality rate was 38% and 1-year survival rate 17%; no patient lived for 2 years. For distal cholangiocarcinoma the operative mortality rate was 45% and one-year survival rate 26%; no patient lived for 3 years. Only palliative procedures were undertaken for diffuse cholangiocarcinoma; 2 patients survived 1 year (13%). Overall 5 patients with carcinoma of the extrahepatic biliary tree appear to have been cured (2%). PMID:2988399

  11. The role of the gallbladder in humans.

    2013-01-01

    The basic function of the gallbladder in humans is one of protection. The accumulation of the primary bile acids (cholic acid and chenodeoxycholic acid) in the gallbladder reduces the formation of the secondary bile acids (deoxycholic acid and lithocholic acid), thus diminishing their concentration in the so-called gallbladder-independent enterohepatic circulation and protecting the liver, the stomach mucosa, the gallbladder, and the colon from their toxic hydrophobic effects. The presence or absence of the gallbladder in mammals is a determining factor in the synthesis of hydrophobic or hydrophilic bile acids. Because the gallbladder contracts 5-20 min after food is in the stomach and the "gastric chyme" moves from the stomach to the duodenum 1-3 h later, the function of the gallbladder bile in digestion may be insignificant. The aim of this article was to provide a detailed review of the role of the gallbladder and the mechanisms related to bile formation in humans. PMID:23683886

    Normal gallbladder scintigraphy occurs in 2 to 5% of reported patients with acute cholecystitis. Gallbladder visualization is found in patients with acalculous cholecystitis and in those with recent relief of cystic duct obstruction but persistence of inflammation. A patient is reported who had clinical and pathologic findings of acute cholecystitis but normal gallbladder visualization. This reemphasizes that the diagnosis of acute cholecystitis cannot be excluded by normal gallbladder scintigraphy.

    Cystoisospora belli, previously known as Isospora belli, is an obligate intracellular coccidian parasite that is most often associated with gastrointestinal disease in immunocompromised patients. In this study, we detail the clinicopathologic features of 18 cases of Cystoisospora infection affecting the gallbladder in immunocompetent individuals and compare them with a control group. Each case was reviewed for cholecystitis (none, acute, chronic), epithelial disarray, presence of intraepithelial lymphocytes (none, rare [≤5 per 20 epithelial cells], present [>5 per 20 epithelial cells]), architectural distortion, intramucosal eosinophilia, and mural thickening/serositis. The mean age of patients with Cystoisospora infection was 33 years and the male to female ratio 1:4.3. Cholecystectomy was performed for biliary dyskinesia (n=7), abdominal pain (n=7), suspected cholelithiasis (n=5), and cholecystitis (n=3). In 2 cases, Cystoisospora was found in donor gallbladders resected at the time of liver transplantation. Each case was characterized by eosinophilic, oval or banana-shaped intraepithelial parasites within perinuclear parasitophorous vacuoles. Most cases showed epithelial disarray and minimal intraepithelial lymphocytosis. Of the 11 cases with an average follow-up of 15 months, none had evidence of disease related to Cystoisospora infection within the biliary tract or elsewhere in the gastrointestinal tract. We present the largest series of gallbladder cystoisosporiasis in immunocompetent patients to date. Cystoisospora infection is underrecognized in the gallbladders of immunocompetent patients, in part due to the subtle findings in routine cholecystectomy specimens. On the basis of the clinical follow-up, gallbladder cystoisosporiasis in immunocompetent individuals appears to be a self-limited infection. PMID:27158759

    Oleanolic acid (OA), a naturally occurring triterpenoid, exhibits potential antitumor activity in many tumor cell lines. Gallbladder carcinoma is the most common malignancy of the biliary tract, and is a highly aggressive tumor with an extremely poor prognosis. Unfortunately, the effects of OA on gallbladder carcinoma are unknown. In this study, we investigated the effects of OA on gallbladder cancer cells and the underlying mechanism. The results showed that OA inhibits proliferation of gallbladder cancer cells in a dose-dependent and time-dependent manner on MTT and colony formation assay. A flow cytometry assay revealed apoptosis and G0/G1 phase arrest in GBC-SD and NOZ cells. Western blot analysis and a mitochondrial membrane potential assay demonstrated that OA functions through the mitochondrial apoptosis pathway. Moreover, this drug inhibited tumor growth in nude mice carrying subcutaneous NOZ tumor xenografts. These data suggest that OA inhibits proliferation of gallbladder cancer cells by regulating apoptosis and the cell cycle process. Thus, OA may be a promising drug for adjuvant chemotherapy in gallbladder carcinoma. PMID:26109845

    Congenital agenesis of the gallbladder is a rare anomaly which is usually asymptomatic and found incidentally. In some cases, however, patients are symptomatic. Common symptoms include right upper quadrant abdominal pain, nausea, and vomiting. Jaundice is present in some symptomatic cases and is due to associated choledocholithiasis (Fiaschetti et al. 2009). In this case, a 63-year-old female presents with jaundice and episodic right upper quadrant abdominal pain with nausea and vomiting. Bilirubin and alkaline phosphatase were found to be markedly elevated. Upper endoscopic ultrasound (EUS) revealed choledocholithiasis, and the patient required multiple endoscopic retrograde cholangiopancreatography (ERCP) sessions before successful extraction of all stones. Subsequent surgical exploration revealed congenital agenesis of the gallbladder. Although this is a rare finding, patients with agenesis of the gallbladder are at increased risk of developing de novo choledocholithiasis which may be challenging to extract. PMID:26185691

Three distinct patterns were identified: (a) a hyperechoic similunar structure with acoustic shadowing posteriorly, simulating a stone-filled gallbladder devoid of bile, which was seen in 5 patients; (b) a biconvex, curvilinear echogenic structure with variable acoustic shadowing, seen in all 3 patients with carcinoma of the gallbladder; and (c) an irregular clump of echoes with posterior acoustic shadowing, seen in 1 patient. Potential pitfalls in the diagnosis of gallbladder calcification are presented, and the association between calcification and cancer is emphasized.

    An interventional radiologist is frequently called to evaluate and treat biliary diseases in children; a tailored approach specific to this population is required. Imaging with an emphasis on minimizing ionizing radiation is used not only in the initial workup but also to guide interventions. The most common form of intervention generally consists of transhepatic biliary drainage to treat either biliary obstruction or bile leakage, a scenario frequently encountered after pediatric liver transplantation. Other pathologies referred for evaluation and management include biliary atresia and, rarely, symptomatic choledochal cysts. Biliary complications caused by an underlying malignancy are not a frequently encountered problem in the pediatric population. The initial evaluation, role of preprocedural imaging, and interventional management with an emphasis on technique are discussed regarding these common biliary pathologies in children. PMID:26615168

    Biliary scintigraphy and ultrasound imaging were performed in 52 patients with suspected biliary tract pathology. Results were correlated with the findings of direct cholangiography. Several new innovations in scintigraphic technique were used. The combination of ultrasound imaging and scintigraphy correctly identified biliary tract obstruction in 17 of 19 patients, 12 of whom had dilated bile ducts on ultrasonography. Intrahepatic cholestasis was correctly diagnosed in 11 of 13 patients. Accurate discrimination between intrahepatic and extrahepatic cholestasis was achieved in 28 of 32 patients (88%) with the combined studies. Scintigraphy also provided a correct diagnosis of acute cholecystitis in all 9 patients with surgically confirmed disease. Eleven additional patients with gallbladder or pancreatic disease had normal bile ducts at scintigraphy, which was confirmed with cholangiography. When combined with ultrasound imaging, modern biliary scintigraphy can (a) provide excellent discrimination between intrahepatic and extrahepatic cholestasis and (b) help determine the need for subsequent invasive diagnostic studies in selected patients.

    Agenesis of the gallbladder with normal bile ducts is a rare anomaly. More cases have been reported preoperatively because of the increased awareness of this entity. However some cases remain difficult to diagnosis. We report such a case. A symptomatic male patient (age 45) was diagnosed with chronic atrophic cholecystitis and cholecystlithiasis by ultrasonography and computed tomography scan. The images revealed solid tissue in the gallbladder fossa. However, during laparoscopic exploration no gallbladder or ectopic gallbladder was found. Only adipose tissue and the gallbladder artery were identified during the operation. Gallbladder agenesis was diagnosed postoperatively. It still remains a challenge to determine surgical intervention in these cases. PMID:20583414

    Gall-bladder mucin is a densely glycosylated macromolecule which is the primary secretory product of the gall-bladder epithelium. It has been shown to bind cholesterol and other biliary lipids and to promote cholesterol crystal nucleation in vitro. In order to understand the molecular basis for mucin-lipid interactions, bovine gall-bladder mucin cDNAs were identified by expression cloning and were isolated and sequenced. The nucleotide sequences of these cDNAs revealed two distinct tandem repeating domains. One of these domains contained a 20-amino acid tandem repeating sequence enriched in threonine, serine and proline. This sequence was similar to, but not identical with, the short tandem repeating sequences identified previously in other mammalian mucins. The other domain contained a 127-amino acid tandem repeating sequence enriched in cysteine and glycine. This repeat displayed considerable sequence similarity to a family of receptor- and ligand-binding proteins containing scavenger receptor cysteine-rich repeats. By analogy with other proteins containing these cysteine-rich repeats, it is possible that, in gall-bladder mucin, this domain serves as a binding site for hydrophobic ligands such as bilirubin, cholesterol and other biliary lipids.

    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.

    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.

    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

    Laparoscopic cholecystectomy (LC) may inhibit the discovery of unsuspected gallbladder cancer, and the effect of LC on the prognosis of gallbladder cancer is unknown. We present two cases of unsuspected gallbladder cancer removed laparoscopically and report the discovery of peritoneal tumor implantation at the umbilical port site 21 days after LC. Although gallbladder carcinoma flow cytometry has been reported to be of prognostic value by Japanese investigators, this technique did not distinguish herein between an invasive adenocarcinoma and carcinoma in situ. A cellular doubling time of 56 h was calculated from one tumor. When unsuspected invasive gallbladder cancer is found after LC, laparoscopic port sites should be inspected at reoperation and, at a minimum, the port site through which the gallbladder was removed should be widely excised. This demonstration of cancer recurrence in laparoscopic port sites may limit the application of laparoscopy to elective cancer resection. PMID:8059312

    Hepatobiliary and pancreatic ascariasis occur due to migration of the round worm ascaris lumbricoides through the bile duct orifice finally reaching the common bile duct, main pancreatic duct, intrahepatic ducts or gallbladder. These resulted in acute epigastric and right hypochondriac region colicky pain. Ultrasound is the investigation of choice in hepatobiliary ascariasis. We present here sonographic images on four pediatric patients with acute biliary colic. PMID:26690772

    Background Patients with perihilar cholangiocarcinoma and gallbladder cancer extending into the hilum often present with jaundice and a small future liver remnant (FLR). If resectable, preoperative biliary drainage and portal vein embolization (PVE) are indicated. Classically, these measures have been performed sequentially, separated by 4–6 weeks. Purpose To report on a new regime where percutaneous transhepatic biliary drainage (PTBD) and PVE are performed simultaneously, shortening the preoperative process. Material and Methods Six patients were treated with concurrent PTBD and PVE under general anesthesia. Results Surgical exploration followed the combined procedure after 35 days (range, 28–51 days). The FLR ratio increased from 22% to 32%. Three patients developed cholangitis after the procedure. Conclusion The combined approach of PTBD and PVE seems feasible, but more studies on morbidity are warranted. PMID:25992300

    Obesity, diabetes, and hyperlipidemia are known risk factors for the development of gallstones. A growing body of animal and human data has correlated insulin resistance with organ dysfunction. The relationship among obesity, diabetes, hyperlipidemia, and abnormal gallbladder motility remains unclear. Therefore, we designed a study to investigate the association among obesity, insulin resistance, hyperlipidemia, and gallbladder dysmotility. One hundred ninety-two healthy adult nondiabetic volunteers were studied. Gallbladder ultrasounds were performed before and after a standardized fatty meal. A gallbladder ejection fraction (EF) was calculated, and an EF of < 25% was considered abnormal. Serum was analyzed for cholesterol, triglycerides, cholecystokinin, leptin, glucose, and insulin. The homeostasis assessment model (HOMA) was used to determine insulin resistance. The volunteers had a mean age of 38 years (range, 18-77), and 55% were female. Thirty subjects (15%) had gallstones and were excluded from the study. Thirty subjects (19%) had abnormal gallbladder motility (EF < 25%). In lean subjects (n = 96) fasting glucose was significantly increased in the 16 subjects with gallbladder EF < 25% versus the 80 subjects with gallbladder EF > 25% (109 +/- 20 mg/dl versus 78 +/- 2 mg/dl, P < 0.05). Similarly, the HOMA index was significantly greater in subjects with gallbladder EF < 25% versus gallbladder EF >25% (3.3 +/- 1.2 versus 2.0 +/- 0.2, P < 0.05). In obese subjects (n = 66), fasting glucose, insulin, and insulin resistance were not associated with a gallbladder EF < 25%. These data suggest that in lean, nondiabetic volunteers without gallstones, gallbladder dysmotility is associated with an elevated fasting glucose as well as a high index of insulin resistance. We conclude that insulin resistance alone may be responsible for gallbladder dysmotility that may result in acalculous cholecystitis or gallstone formation. PMID:16843864

    Gallbladder cancer is a rather uncommon disease, when it gives symptoms it has usually reached an incurable stage. Therefore, every attempt must be made to find the asymptomatic stages and look for premalignant gallbladder polyps. Even if gallbladder cancer is a rare disease, gallbladder polyps are common, only a few polyps develop to cancer. This makes gallbladder polyps another problem: which are the polyps that must be surgically removed, which shall be followed-up, or for how long? The author used the keyword “gallbladder polypsn” in PubMed and reviewed the scientific literatures published from January 2000 to December 2011. The present review article has summarized almost all respects of gallbladder polyp, including the risk factors, clinical diagnosis and management, and comments made from the author, in which clinical treatments are recommended. It is author's purpose that the 11-year-knowledge about gallbladder polyps summarized from all worlds’ literatures is enough to know how clinicians will handle the next patient with gallbladder polyp.

    Background/Aims Surgery is the mainstay of treatment for cholecystitis. However, gallbladder stenting (GBS) has shown promise in debilitated or high-risk patients. Endoscopic transpapillary GBS and endoscopic ultrasound-guided GBS (EUS-GBS) have been proposed as safe and effective modalities for gallbladder drainage. Methods Data from patients with cholecystitis were prospectively collected from August 2004 to May 2013 from two United States academic university hospitals and analyzed retrospectively. The following treatment algorithm was adopted. Endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy and cystic duct stenting was initially attempted. If deemed feasible by the endoscopist, EUS-GBS was then pursued. Results During the study period, 139 patients underwent endoscopic gallbladder drainage. Among these, drainage was performed in 94 and 45 cases for benign and malignant indications, respectively. Successful endoscopic gallbladder drainage was defined as decompression of the gallbladder without incidence of cholecystitis, and was achieved with ERCP and cystic duct stenting in 117 of 128 cases (91%). Successful endoscopic gallbladder drainage was also achieved with EUS-guided gallbladder drainage using transmural stent placement in 11 of 11 cases (100%). Complications occurred in 11 cases (8%). Conclusions Endoscopic gallbladder drainage techniques are safe and efficacious methods for gallbladder decompression in non-surgical patients with comorbidities. PMID:26473125

    The precipitation of excess biliary cholesterol as solid crystals is a prerequisite for cholesterol gallstone formation, which occurs due to disturbed biliary homeostasis. Biliary homeostasis is regulated by an elaborate network of genes in hepatocytes. If unmanaged, the cholesterol crystals will aggregate, fuse and form gallstones. We have previously observed that the levels of osteopontin (OPN) in bile and gallbladder were reduced in gallstone patients. However, the role and mechanism for hepatic OPN in cholesterol gallstone formation is undetermined. In this study, we found that the expression of hepatic OPN was increased in gallstone patients compared with gallstone-free counterparts. Then, we observed that OPN-deficient mice were less vulnerable to cholesterol gallstone formation than wild type mice. Further mechanistic studies revealed that this protective effect was associated with alterations of bile composition and was caused by the increased hepatic CYP7A1 expression and the reduced expression of hepatic SHP, ATP8B1, SR-B1 and SREBP-2. Finally, the correlations between the expression of hepatic OPN and the expression of these hepatic genes were validated in gallstone patients. Taken together, our findings reveal that hepatic OPN contributes to cholesterol gallstone formation by regulating biliary metabolism and might be developed as a therapeutic target for gallstone treatments.

    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

    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

    Double gallbladder is one of the rare congenital anomalies of the gallbladder. Failure to detect an accessory gallbladder hampers diagnosis and treatment of cholecystitis, which might result in recurrent attacks of cholecystitis. In addition, presence of peritoneal folds extending from the stomach and duodenum to the gallbladder is very rare. Here we report the presence of a double gallbladder enclosed in a cystogastric fold of the peritoneum. During cadaveric dissection, we observed a cystogastric peritoneal fold that extended from the lesser curvature of the stomach and the first part of the duodenum to the gallbladder. The left end of the peritoneal fold merged with the lesser omentum. It enclosed two gallbladders: the main gallbladder and a small accessory gallbladder. The accessory gallbladder was a small pouch with its fundus attached to the main gallbladder by fibrous tissue, and its duct opened into the main cystic duct. PMID:24987550

    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

    The purpose of this work was to study principles of bile structurization in healthy people and patients with various biliary diseases. 160 patients with different biliary diseases and other diseases of the hepatopancreaticoduodenal zone were examined. Samples of gallbladder bile were taken from corpses of young men, who did not have any diseases of the hepatopancreaticoduodenal zone. Their diagnoses were confirmed by an ultrasound morphological study. Bile was studied by the cuneate dehydration and viscosimetric methods. The structure of facies of gallbladder bile under conditions of absence of diseases of the hepatopancreaticoduodenal zone was shown. The facies have a wide convex peripheral zone (a cushion) without any well-defined border. The central part of the facies is amorphous or fine-grained, sometimes with occasional inclusions of larger crystals. Markers of exacerbation of chronic cholecystitis (dendrites in the central zone of bile facies) as well as signs of the presence of a malignant neoplasm touching the bile (large diamond-shaped crystals in the central zone of bile facies where dendrites begin) were discovered.

    In recent years, some Chinese doctors have proposed a new concept, gallstone removal without gallbladder excision, along with transition of the medical model. As there is no specialized endoscope for gallstone removal without gallbladder excision, we designed and produced a new series of gallbladder endoscopes and accessories that have already been given a Chinese invention patent (No. ZL200810199041.2). The design of these gallbladder endoscopes was based on the anatomy and physiology of the gallbladder, characteristics of gallbladder disease, ergonomics, and industrial design. This series of gallbladder endoscopes underwent clinical trials in two hospitals appointed by the State Administration of Traditional Chinese Medicine. The clinical trials showed that surgeries of gallstones, gallbladder polyps, and cystic duct calculus could be smoothly performed with these products. In summary, this series of gallbladder endoscopes is safe, reliable, and effective for gallstone removal without gallbladder excision. This note comprehensively introduces the research and design of this series of gallbladder endoscopes.

    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

    2013-01-01

    Summary Background High carbohydrate intake has been linked to insulin resistance, obesity, and abnormal serum lipid profiles—conditions which favor gallstone formation. Goals The aim of this study was to evaluate the effect of dietary carbohydrate intake on incident gallbladder disease, defined as biliary sludge and stones, during pregnancy. Study We prospectively studied 3,070 pregnant women who underwent serial gallbladder ultrasound during pregnancy and at 4-6 weeks postpartum. All women had at least 2 study ultrasounds for comparison. A semi-quantitative food frequency questionnaire was completed by subjects in the early 3rd trimester. Multivariate logistic regression was performed to assess the risk of incident gallbladder disease across quartiles total and individual carbohydrate and individual carbohydrates (starch, sucrose, galactose, fructose, and lactose) intake. Results The cumulative incidence of gallbladder disease was 10.2% by 4-6 weeks postpartum. The risk of incident gallbladder disease during pregnancy was significantly higher among women in the highest quartile of total carbohydrate intake vs. those in the lowest quartile (odds ratio 2.09, 95% confidence interval 1.02-4.27). High intake of fructose was associated with increased risk even after additional adjustment for total carbohydrate intake (odds ratio 2.18, 95% confidence interval 1.23-3.86, comparing highest to lowest quartile). No association was found between the intake of starch, sucrose, lactose, or galactose and the risk of incident gallbladder disease. Conclusions High consumption of total carbohydrate and fructose may increase the risk of developing gallbladder disease during pregnancy. Dietary modification during pregnancy might reduce gallstone incidence during this time period. PMID:23442841

  8. Models of gastric emptying.

    1977-01-01

    Some empirical and theoretical models of the emptying behaviour of the stomach are presented. The laws of Laplace, Hooke, and Poisseuille are used to derive a new model of gastric emptying. Published data on humans are used to test the model and evaluate empirical constants. It is shown that for meals with an initial volume of larger than or equal to 300 ml, the reciprocal of the cube root of the volume of meal remaining is proportional to the time the meal is in the stomach.For meals of initial volume of less than 300 ml the equation has to be corrected for the fact that the 'resting volume' of gastric contents is about 28 ml. The more exact formula is given in the text. As this model invokes no neural or hormonal factors, it is suggested that the gastric emptying response to the volume of a meal does not depend on these factors. The gastric emptying response to the composition of the meal does depend on such factors and a recent model of this process is used to evaluate an empirical constant. PMID:856678

    Background 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. Case report 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. Conclusions Imaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions. PMID:23801908

    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.

    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

    Objective We wanted to describe the computed tomography (CT) findings of gallbladder tuberculosis (TB) and to correlate them with pathologic findings. Materials and Methods There were seven patients (M:F = 3:4; mean age, 46.3 years; age range, 32 to 78 years) in whom gallbladder TB was eventually diagnosed. All of them underwent cross-sectional imaging with CT, a pathologic examination and a retrospective review. CT imaging evaluation was done in each case, including the findings of a mass versus nodule, wall thickening (uniform or irregular) and the enhancement patterns (homogeneous or heterogeneous). Results All the cases of gallbladder TB revealed the following three different CT findings: micronodular lesion of the gallbladder wall (n = 1), a thickened wall (n = 4) and a gallbladder mass (n = 2). There were three cases of homogeneous enhancement of the lesions, including homogeneous enhancement with nodular lesion, homogeneous uniform thickness enhancement and homogeneous thickness enhancement in one case each, and these cases pathology showed tuberculous granuloma with a little caseating necrosis in one case and tuberculous granuloma with rich fibrous tissue, but little or no evident caseating necrosis in two cases. Four cases of heterogeneous enhancement of the lesions, including heterogeneous uniform-thickness enhancement in two cases, heterogeneous enhancement with a local mass lesion in one case and heterogeneous enhancement with a mass that replaced the gallbladder in one case; in these cases, pathology showed tuberculous granuloma with marked caseation or liquefaction necrosis in three cases and tuberculous granuloma by fibrous and calcifications accompanied by caseating necrosis in one case. Among the seven cases of gallbladder TB, six cases were accompanied by abdominal extra-gallbladder TB, including abdominal lymph node TB in five cases and hepatic TB in four cases. Conclusion Gallbladder TB has various CT manifestations, and the enhanced CT findings

    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

    A 40-yr-old female chimpanzee (Pan troglodytes) presented with intermittent, short-duration episodes of nonspecific clinical signs that included lethargy and reduced responsiveness to external stimuli. Clinical examination and diagnostics suggested obstructive hepatic disease, which was confirmed by subsequent ultrasonographic examination. During routine laparotomy, a biliary calculus was removed from the distal common bile duct and the gallbladder was removed, which resulted in complete clinical recovery. The biliary calculus was analyzed as a mixed composition of predominantly cholesterol, bilirubin, and calcium. PMID:26667553

    Introduction Gall bladder perforation is associated with high mortality rates and therefore must be recognised and managed promptly. We present an unusual presentation of spontaneous gall bladder perforation. Case presentation An elderly lady with multiple medical co-morbidities was admitted with sepsis following a fall. Initial assessment lead to a diagnosis of pneumonia, however a rapidly expanding right flank mass was incidentally noted during routine nursing care. Imaging studies were inconclusive, however incision and drainage of the mass revealed bile stained pus draining cutaneously from an acutely inflamed gallbladder. The patient made a good recovery following surgery, and was discharged with outpatient follow-up. Discussion Despite focussed post-hoc history taking she denied any prodromal symptoms of cholecystitis. In addition to reporting an unusual cause for a common presentation, we highlight the importance of a full body examination in the context of sepsis, regardless of whether the source has been identified. In addition, we advocate that surgical intervention in sepsis should not be delayed by imaging in cases where an abscess is suspected. Conclusions Percutaneous abscesses arising from the gallbladder are a rare but potentially serious consequence of acute cholecystitis, and may present in a wide variety of locations. Therefore it is imperative to conduct a full body inspection in the septic patient, even when a source has been identified. PMID:26686488

    Gallbladder cancer is usually associated with gallstone disease, late diagnosis, unsatisfactory treatment, and poor prognosis. We report here the worldwide geographical distribution of gallbladder cancer, review the main etiologic hypotheses, and provide some comments on perspectives for prevention. The highest incidence rate of gallbladder cancer is found among populations of the Andean area, North American Indians, and Mexican Americans. Gallbladder cancer is up to three times higher among women than men in all populations. The highest incidence rates in Europe are found in Poland, the Czech Republic, and Slovakia. Incidence rates in other regions of the world are relatively low. The highest mortality rates are also reported from South America, 3.5-15.5 per 100,000 among Chilean Mapuche Indians, Bolivians, and Chilean Hispanics. Intermediate rates, 3.7 to 9.1 per 100,000, are reported from Peru, Ecuador, Colombia, and Brazil. Mortality rates are low in North America, with the exception of high rates among American Indians in New Mexico (11.3 per 100,000) and among Mexican Americans. The main associated risk factors identified so far include cholelithiasis (especially untreated chronic symptomatic gallstones), obesity, reproductive factors, chronic infections of the gallbladder, and environmental exposure to specific chemicals. These suspected factors likely represent promoters of carcinogenesis. The main limitations of epidemiologic studies on gallbladder cancer are the small sample sizes and specific problems in quantifying exposure to putative risk factors. The natural history of gallbladder disease should be characterized to support the allocation of more resources for early treatment of symptomatic gallbladder disease in high-risk populations. Secondary prevention of gallbladder cancer could be effective if supported by cost-effective studies of prophylactic cholecystectomy among asymptomatic gallstone patients in high-risk areas.

    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.

    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.

A correct preoperative diagnosis of GT is difficult. The final diagnosis is usually made postoperatively according to surgical biopsy. Here, we report a case of a patient who underwent surgery with the preoperative diagnosis of gallbladder carcinoma. We reviewed the literature and present the process of differential diagnosis between two or more conditions that share similar signs or symptoms. PMID:27200195

    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.

    From 1976 to 1988, 63 patients received radiation therapy for primary cancers of the extrahepatic biliary system (eight gallbladder and 55 extrahepatic biliary duct). Twelve patients underwent orthotopic liver transplantation. Chemotherapy was administered to 13 patients. Three patients underwent intraluminal brachytherapy alone (range, 28 to 55 Gy). Sixty patients received megavoltage external-beam radiation therapy (range, 5.4 to 61.6 Gy; median, 45 Gy), of whom nine received additional intraluminal brachytherapy (range, 14 to 45 Gy; median, 30 Gy). The median survival of all patients was 7 months. Sixty patients died, all within 39 months of radiation therapy. One patient is alive 11 months after irradiation without surgical resection, and two are alive 50 months after liver transplantation and irradiation. Symptomatic duodenal ulcers developed after radiation therapy in seven patients but were not significantly related to any clinical variable tested. Extrahepatic biliary duct cancers, the absence of metastases, increasing calendar year of treatment, and liver transplantation with postoperative radiation therapy were factors significantly associated with improved survival.

    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

    Background/Aims Nonalcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease worldwide. Along with the increase in the incidence of NAFLD and associated obesity, an increase in gallbladder disease (GD) has been noted. This has led to the identification of a new disease entity called fatty GD. There is a gap in the literature on the dynamics of gallbladder function in patients with NAFLD. Methods An observational case-control study, a total of 50 patients with biopsy proven NAFLD without gallbladder stone/sludge and 38 healthy comparison subjects were enrolled. Fasting, postprandial gallbladder volumes (PGV), gallbladder ejection fraction (GEF), and fasting gallbladder wall thickness (FGWT) were measured by real-time 2-dimensional ultrasonography. Results Fasting gallbladder wall thickness, fasting gallbladder volumes and PGV were significantly higher in patients with NAFLD than control subjects (P < 0.001, P = 0.006, and P < 0.001, respectively). Gallbladder ejection fraction was significantly lower in the NAFLD group than the controls (P = 0.008). The presence of NAFLD was an independent predictor for GEF, PGV, and FGWT. Also, steatosis grade was an independent predictor for GEF, and GEF was significantly lower in the nonalcoholic steatohepatitis (NASH) subgroup than the controls. Conclusions Gallbladder dysfunction and increase in gallbladder wall thickness exists in asymptomatic (without stone/sludge and related symptoms) patients with NAFLD and are useful in identifying fatty GD. Measurement of these variables in NAFLD patients may be useful in identifying those at higher risk for GD. PMID:26932908

    Penetrating abdominal trauma is a major killer worldwide. Various modes and mechanisms of injury have been described in world literature. We describe an unusual case of penetrating intra-abdominal injury caused by a 2-ft-long needle fish at sea. The mode and mechanism of injury is rare and the consequences life threatening. There is paucity in the literature of such trauma and its presentation. This case report describes injury sustained by a fisherman at sea by a needle fish, causing biliary peritonitis from an isolated penetrating injury to the gallbladder. Typically, these fishes are known to jump up to 6 ft above the surface of the water and are voracious carnivores, feeding on smaller fishes in deep sea. The fisherman, having sustained the injury, had blood tinged bile oozing from the wound and attended casualty in severe abdominal pain and nausea. Diagnosis was prompt, and even though the presentation to the casualty was delayed, immediate resuscitative measures and surgery ensured successful management of the patient. PMID:27303126

    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 < 0.001), though the contraction rate was not different. The combination of gallbladder contraction rate measurement and residual volume calculation by ultrasonography was superior over traditional OCG. PMID:7555394

    Biliary infections are an important cause of morbidity in the Western world. With regard to epidemiology, etiology, microbiological spectrum, prevalence, location and composition of gallstones, pathogenesis, clinical sign and therapy, there are large differences between the spectrum of biliary infections in the East and in the West (Table 1). In Western countries, gallstones are found in 10 to 40%. In Eastern countries, the incidence of gallstones is only 2 to 6%. Some eighty – five percent of the gallstones in the West are cholesterol stones, in contrast to the East, where 97% are bile pigment stones. The most important difference is characterized by the origin of common bile duct stones. In the West, common bile duct stones generally originate in the gallbladder, in contrast to the East, where primary common bile duct stones are often found – especially in the intrahepatic segments – with no evidence of gallbladder stones. The sex distribution male to female in the West is 1:2, in the East 1:1. In the West, biliary infections occur mainly in an elderly population, 50% being older than 70 years. In the East, biliary infections appear also in younger people, 50% being younger than 40 years. Parasites play an aetiological role in the East, but not in the West. The typical therapy of gallstones in the West is cholecystectomy, and of common bile duct stones endoscopic sphincterotomy. Due to the frequency of intrahepatic stones in Eastern Countries, the therapeutic spectrum there includes even large hepatic resections and biliary enteric anastomoses. PMID:18612470

    In order to develop new therapeutic regimens for biliary tract cancers, which carry dismal prognoses, the establishment of a human biliary tract cancer xenograft model is essential. Herein, we report the successful establishment and characterization of two xenograft models of human biliary tract cancers. An adenosquamous gallbladder cancer cell line (TGBC-44) and a bile duct adenocarcinoma cell line (TGBC-47) were obtained from fresh surgical specimens in our department and subcutaneously inoculated into nude mice. The overall tumor take rate was 100% and solid tumors grew measurable after 5 and 7 days for TGBC-44 and TGBC-47, respectively. Tumor doubling time was 3.9+/-1.1 and 4.1+/-0.5 days in the exponential growth phase in TGBC-44 and TGBC-47 xenografts, respectively. Isozyme test and karyotype analysis confirmed the human origin. Histopathology analysis revealed that the TGBC-44 xenograft retained both the squamous and the adenocarcinoma components, and the TGBC-47 xenograft exhibited poorly differentiated adenocarcinoma as in the corresponding original tumors. Immunohistochemistry and Western blotting studies revealed positive and similar expression of platelet derived endothelial growth factor/thymidine phosphorylase (PDGF/TP), thymidylate synthase (TS), and cyclooxygenase-2 (COX-2) in both original tumors and xenograft models. No macroscopic metastases were found at the time of sacrifice. We have successfully established two models of human biliary tract cancer, gallbladder and bile duct cancer. Models retained the morphological and biochemical characteristics of the original tumor and demonstrated constant biological behavior in all transplanted mice. These models could be useful tools for developing new diagnostic and therapeutic strategies against biliary tract cancers. PMID:14532968

    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 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 into the porcine intestine; therefore, biliary and pancreatic fluid can be individually analyzed in CF pigs. We studied newborn wild-type (WT) and CF pigs and found that CFTR was localized to the pancreatic ducts. We collected bile and pancreatic fluid and analyzed pancreatic enzymes with activity assays and immunoblot. Pancreatic enzyme expression was significantly decreased in CF compared with WT pigs. The volume and pH of pancreatic fluid were significantly lower and protein concentration was >5-fold higher in CF pigs. Secretin stimulation increased pancreatic fluid volume and pH in WT, but not CF, pigs. Baseline bile volume did not differ between WT and CF pigs, but volume did not increase in response to secretin in CF pigs. Bile pH was lower and protein concentration was twofold higher in CF pigs. These results indicate that pancreatic and biliary secretions are altered in CF pigs. Abnormal pancreatic and biliary secretion in CF may have important implications in disease pathogenesis.

    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.

    DNA synthesis activity in the epithelium of the human gallbladder was studied through in vitro labelling of mucosal specimens with 3H-thymidine and autoradiography. The specimens were taken at the time of a surgical operation. Eight 'normal' gallbladders and six distended gallbladders from patients with carcinomatous obstruction of the common bile duct were examined. Proliferative activity was very low in the normal and significantly higher in the distended gallbladders. Images Figure PMID:437558

    Biliary tract cancers (BTCs) are a heterogeneous group of neoplasms characterized by a dismal prognosis. At variance with most solid tumors, no effective molecular targeted agent has been currently approved for BTCs treatment and their molecular landscape has only been recently investigated. Comprehensive mutational profiling studies identified IDH1/2 and BAP1 as characteristic of intrahepatic cholangiocarcinomas, while extrahepatic cholangiocarcinomas and gallbladder carcinomas were characterized by frequent KRAS and TP53 alterations. Moreover, targeted next-generation sequencing has uncovered alterations in several key cellular pathways. BTC-specific alterations include disorders of major regulators of cell cycle and chromatin remodeling processes, as well as deregulation of the mTOR-, TGF-beta/Smad- and receptor tyrosine kinases signaling. The next step will be the correlation of these findings with clinical trials to identify predictive biomarkers for the development of personalized therapies. This will permit early access for BTC patients to innovative drugs. PMID:26709801

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

    The outcome of gallbladder carcinoma is poor, and the overall 5-year survival rate is less than 5%. In early-stage disease, a 5-year survival rate up to 75% can be achieved if stage-adjusted therapy is performed. There is wide geographic variability in the frequency of gallbladder carcinoma, which can only be explained by an interaction between genetic factors and their alteration. Gallstones and chronic cholecystitis are important risk factors in the formation of gallbladder malignancies. Factors such as chronic bacterial infection, primary sclerosing cholangitis, an anomalous junction of the pancreaticobiliary duct, and several types of gallbladder polyps are associated with a higher risk of gallbladder cancer. There is also an interesting correlation between risk factors and the histological type of cancer. However, despite theoretical risk factors, only a third of gallbladder carcinomas are recognized preoperatively. In most patients, the tumor is diagnosed by the pathologist after a routine cholecystectomy for a benign disease and is termed ‘‘incidental or occult gallbladder carcinoma’’ (IGBC). A cholecystectomy is performed frequently due to the minimal invasiveness of the laparoscopic technique. Therefore, the postoperative diagnosis of potentially curable early-stage disease is more frequent. A second radical re-resection to complete a radical cholecystectomy is required for several IGBCs. However, the literature and guidelines used in different countries differ regarding the radicality or T-stage criteria for performing a radical cholecystectomy. The NCCN guidelines and data from the German registry (GR), which records the largest number of incidental gallbladder carcinomas in Europe, indicate that carcinomas infiltrating the muscularis propria or beyond require radical surgery. According to GR data and current literature, a wedge resection with a combined dissection of the lymph nodes of the hepatoduodenal ligament is adequate for T1b and T2

The patient's clinical symptoms were pain, vomiting and abdominal tenderness, and she was thought to have acute appendicitis. However, laboratory examination revealed high serum alkaline phosphatase and amylase levels, and ultrasonography and percutaneous cholangiography demonstrated biliary ascariasis.

    Spontaneous gallbladder perforation is rare in children. The etiology of gallbladder perforation varies greatly and is often unknown. Identified causes include infection, congenital, stones or choledochal cysts. Presently there are only five reported cases of spontaneous gallbladder perforation in children in the English literature. As such, the optimal method of diagnosis and management remains controversial. We report the case of a 2-year-old girl who presented with peritonitis secondary to spontaneous gallbladder perforation.

    We investigated the hypothesis that lysosomes are the main source of biliary copper in conditions of hepatic copper overload. We used a rat model of oral copper loading and studied the relationship between the biliary output of copper and lysosomal hydrolases. Male Sprague-Dawley rats were given tap water with or without 0.125% copper acetate for up to 36 wk. Copper loading produced a 23-fold increase in the hepatic copper concentration and a 30-65% increase in hepatic lysosomal enzyme activity. Acid phosphatase histochemistry showed that copper-loaded livers contained an increased number of hepatocyte lysosomes; increased copper concentration of these organelles was confirmed directly by both x ray microanalysis and tissue fractionation. The copper-loaded rats showed a 16-fold increase in biliary copper output and a 50-300% increase in biliary lysosomal enzyme output. In the basal state, excretory profiles over time were similar for biliary outputs of lysosomal enzymes and copper in the copper-loaded animals but not in controls. After pharmacologic stimulation of lysosomal exocytosis, biliary outputs of copper and lysosomal hydrolases in the copper-loaded animals remained coupled: injection of colchicine or vinblastine produced an acute rise in the biliary output of both lysosomal enzymes and copper to 150-250% of baseline rates. After these same drugs, control animals showed only the expected increase in lysosomal enzyme output without a corresponding increase in copper output. We conclude that the hepatocyte responds to an increased copper load by sequestering excess copper in an increased number of lysosomes that then empty their contents directly into bile. The results provide direct evidence that exocytosis of lysosomal contents into biliary canaliculi is the major mechanism for biliary copper excretion in hepatic copper overload.

    Cutaneous metastasis (CM) is an uncommon manifestation of visceral malignancies. Adenosquamous carcinoma of the gallbladder is a rare variation in gallbladder carcinoma (GBC), associated with worse prognosis. We present the case of a 56-year-old woman who presented with an inflamed lump on her abdominal wall. Computed tomography (CT) revealed a large mass from the gallbladder invading the abdominal wall. She underwent liver resection with regional lymphadenectomy. Pathology analysis revealed a 12-cm pT3N0 GBC. Hospital discharge occurred at post-operative Day 20. She recurred and died 10 months after surgery. Survival after the diagnosis of CM is dismal. The present case was a diagnostic trap. First, the patient's skin lesion presented as a cutaneous abscess and biopsy revealed a squamous cell cancer. A CT scan suggested a continuous mass involving the abdominal wall. CM was only suspected during surgery when no continuity between the tumour and the abdominal wall was identified. PMID:25480835

    Incubation of (1-/sup 14/C)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-/sup 14/C)PGH2 was virtually identical to that of (1-/sup 14/C)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.

    The existence of a lag phase during the gastric emptying of solid foods is controversial. It has been hypothesised that among other early events, the stomach requires a period of time to process solid food to particles small enough to be handled as a liquid. At present no standardised curve fitting techniques exist for the characterisation and quantification of the lag phase or the emptying rate of solids and liquids. We have evaluated the ability of a modified power exponential function to define the emptying parameters of two different solid meals. Dual labelled meals were administered to 24 normal volunteers. The subjects received meals consisting of either Tc-99m in vivo labelled chicken liver or Tc-99m-egg, which have different densities, and In-111-DTPA in water. The emptying curves were biphasic in nature. For solids, this represented an initial delay in emptying or lag phase followed by an equilibrium emptying phase characterised by a constant rate of emptying. The curves were analysed using a modified power exponential function of the form y(t) = 1-(1-e-kt)beta, where y(t) is the fractional meal retention at time t, k is the gastric emptying rate in min-1, and beta is the extrapolated y-intercept from the terminal portion of the curve. The length of the lag phase and half-emptying time increased with solid food density (31 +/- 8 min and 77.6 +/- 11.2 min for egg and 62 +/- 16 min and 94.1 +/- 14.2 min for chicken liver, respectively). After the lag phase, both solids had similar emptying rates, and these rates were identical to those of the liquids. In vitro experiments indicated that the egg meal disintegrated much more rapidly than the chicken liver under mechanical agitation in gastric juice, lending further support to the hypothesis that the initial lag in emptying of solid food is due to the processing of food into particles small enough to pass the pylorus. We conclude that the modified power exponential model permits characterisation of the biphasic

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 problem of overlooking of this entity. Complete identification and removal of gallbladder is mandatory, as a remnant may result in recurrence of symptoms or stones. PMID:19547674

    The debate as to whether to administer ceftriaxone to neonates is likely to continue. Ceftriaxone has numerous advantages for critically ill pediatric patients. However, it is also known to contribute substantially to the development of biliary pseudolithiasis. Although pediatric patients rarely develop gallbladder disorders, this complication may lead to adverse events in high-risk patients with predisposing factors, particularly in neonates and infants treated with ceftriaxone. In this paper we present an interesting case report of a 28-day-old neonate with spontaneous severe epidural hematoma who developed biliary pseudolithiasis related to the use of ceftriaxone. We also discuss the efficacy of ceftriaxone in neonates and infants. Neonatologists and pediatric intensivists should be aware of the higher risk of co-existence of hyperbilirubinemia and gallbladder disorders while using ceftriaxone in pediatric settings.

    Upton et al. J Protozool 35:24-25, 1988 originally described Eimeria turcicus from the gallbladder of the Mediterranean gecko, Hemidactylus turcicus, in the USA. Shortly after establishing the genus Choleoeimeria, Paperna and Landsberg S Afr J Zool 24:345-355, 1989 transferred E. turcicus to this genus, renaming it as Choleoeimeria turcicus. This paper reports the findings of a survey of coccidian parasites of lizards in Egypt, during which tetrasporocystic oocysts were reported from the gallbladder of H. turcicus. Based on the oocysts' morphological and morphometric characteristics and the same host, it can be deduced for the first time that the present species is conspecific with E. turcicus. In the present study, the gallbladder was the sole site for the endogenous development and no endogenous stages were noticed in the intestine. The endogenous stages induce hypertrophy and displacement of the infected cells from the original biliary epithelium to form a prolonged and branching outgrowth. We therefore followed Paperna and Landsberg S Afr J Zool 24:345-355, 1989 and considered the biliary coccidium recorded in this study to be a member of the genus Choleoeimeria. This represents a new locality record for C. turcicus, which was previously known in the USA and Israel. PMID:26857128

    A 54-year-old Japanese woman was referred with a gallbladder tumor. Based on the results of the computed tomography scan, endoscopic retrograde cholangiopancreatography, and magnetic resonance cholangiopancreatography, a mucin-producing neoplasm of the gallbladder associated with pancreaticobiliary maljunction was diagnosed. Extended cholecystectomy, extrahepatic bile duct resection, and choledochojejunostomy were performed, and she remains free of recurrence 24 months after resection. Histopathological examination revealed that the papillary component of the lesion was an intracystic papillary neoplasm with diverse characteristics of pancreaticobiliary epithelium and intestinal epithelium including mucin. In this component, most of the papillary lesion was a high-grade intraepithelial neoplasm, but also showed slight invasion into the muscular layer. The nodular component consisted of both poorly differentiated biliary type adenocarcinoma and large cell neuroendocrine carcinoma. We report a rare case of a mixed adenoneuroendocrine carcinoma arising from an intracystic papillary neoplasm associated with pancreaticobiliary maljunction. As for the histogenesis of this tumor, based on the histopathologic appearance, transdifferentiation from poorly differentiated biliary type adenocarcinoma to large cell neuroendocrine carcinoma is considered the most possible histogenesis of this tumor.

    PURPOSE: The use of laparoscopy in the treatment of biliary atresia (BA) is still debated. We report our strategy using laparoscopy in type I cystic BA. MATERIALS AND METHODS: We reviewed the records of patients treated for BA from 2002-2013. When the diagnosis was suspected, an ultrasound was performed. If it showed a cyst > 5 mm in the hilum with no patent gallbladder, we performed an initial explorative laparoscopy. In the case of a patent biliary tree above the cyst, a laparoscopic cystojejunostomy was performed. In cases of absent communication (type III), conversion and portoenterostomy were performed. Pre and postoperative data and overall survival rate with the native liver were reviewed. RESULTS: Forty-four children were treated for BA. Six presented with a cystic form diagnosed by US. Three children had type I BA; three had type III BA. No postoperative complications were noted. Median follow-up was 62.2 months (22.7-93.5). One patient died of a cardiac malformation. The five remaining patients are alive with their native liver. Of the 38 treated for noncystic BA, 16 were transplanted. CONCLUSION: We confirmed the prognosis of cystic BA, which is less severe than noncystic BA. Our strategy using laparoscopy allowed for the confirmation and qualification of the type of BA. In type I, complete treatment by laparoscopy has been performed safely. PMID:26622117

    AIM: To investigate the diagnostic and therapeutic assessment in children with adenomyomatosis of the gallbladder (AMG). METHODS: AMG is a degenerative disease characterized by a proliferation of the mucosal epithelium which deeply invaginates and extends into the thickened muscular layer of the gallbladder, causing intramural diverticula. Although AMG is found in up to 5% of cholecystectomy specimens in adult populations, this condition in childhood is extremely uncommon. Authors provide a detailed systematic review of the pediatric literature according to PRISMA guidelines, focusing on diagnostic and therapeutic assessment. An additional case of AMG is also presented. RESULTS: Five studies were finally enclosed, encompassing 5 children with AMG. Analysis was extended to our additional 11-year-old patient, who presented diffuse AMG and pancreatic acinar metaplasia of the gallbladder mucosa and was successfully managed with laparoscopic cholecystectomy. Mean age at presentation was 7.2 years. Unspecific abdominal pain was the commonest symptom. Abdominal ultrasound was performed on all patients, with a diagnostic accuracy of 100%. Five patients underwent cholecystectomy, and at follow-up were asymptomatic. In the remaining patient, completely asymptomatic at diagnosis, a conservative approach with monthly monitoring via ultrasonography was undertaken. CONCLUSION: Considering the remote but possible degeneration leading to cancer and the feasibility of laparoscopic cholecystectomy even in small children, evidence suggests that elective laparoscopic cholecystectomy represent the treatment of choice. Pre-operative evaluation of the extrahepatic biliary tree anatomy with cholangio-MRI is strongly recommended. PMID:27170933

    Gallbladder cancer is a lethal disease with notable geographical variations worldwide and a predilection towards women. Its main risk factor is prolonged exposure to gallstones, although bacterial infections and other inflammatory conditions are also associated. The recurrent cycles of gallbladder epithelium damage and repair enable a chronic inflammatory environment that promotes progressive morphological impairment through a metaplasia-dysplasia-carcinoma, along with cumulative genome instability. Inactivation of TP53, which is mutated in over 50% of GBC cases, seems to be the earliest and one of the most important carcinogenic pathways involved. Increased cell turnover and oxidative stress promote early alteration of TP53, cell cycle deregulation, apoptosis and replicative senescence. In this review, we will discuss evidence for the role of inflammation in gallbladder carcinogenesis obtained through epidemiological studies, genome-wide association studies, experimental carcinogenesis, morphogenetic studies and comparative studies with other inflammation-driven malignancies. The evidence strongly supports chronic, unresolved inflammation as the main carcinogenic mechanism of gallbladder cancer, regardless of the initial etiologic trigger. Given this central role of inflammation, evaluation of the potential for GBC prevention removing causes of inflammation or using anti-inflammatory drugs in high-risk populations may be warranted.

    Abstract Enhanced computed tomography (CT) is widely used for evaluating acute biliary pain in the emergency department (ED). However, concern about radiation exposure from CT has also increased. We investigated the usefulness of pre-contrast CT for differential diagnosis in middle-aged subjects with suspected biliary pain. A total of 183 subjects, who visited the ED for suspected biliary pain from January 2011 to December 2012, were included. Retrospectively, pre-contrast phase and multiphase CT findings were reviewed and the detection rate of findings suggesting disease requiring significant treatment by noncontrast CT (NCCT) was compared with cases detected by multiphase CT. Approximately 70% of total subjects had a significant condition, including 1 case of gallbladder cancer and 126 (68.8%) cases requiring intervention (122 biliary stone-related diseases, 3 liver abscesses, and 1 liver hemangioma). The rate of overlooking malignancy without contrast enhancement was calculated to be 0% to 1.5%. Biliary stones and liver space-occupying lesions were found equally on NCCT and multiphase CT. Calculated probable rates of overlooking acute cholecystitis and biliary obstruction were maximally 6.8% and 4.2% respectively. Incidental significant finding unrelated with pain consisted of 1 case of adrenal incidentaloma, which was also observed in NCCT. NCCT might be sufficient to detect life-threatening or significant disease requiring early treatment in young adults with biliary pain. PMID:25700321

    At present, little is known regarding Listeria monocytogenes-associated biliary tract infection, a rare form of listeriosis.In this article, we will study 12 culture-proven cases reported to the French National Reference Center for Listeria from 1996 to 2013 and review the 8 previously published cases.Twenty cases were studied: 17 cholecystitis, 2 cholangitis, and 1 biliary cyst infection. Half were men with a median age of 69 years (32-85). Comorbidities were present in 80%, including cirrhosis, rheumatoid arthritis, and diabetes. Five patients received immunosuppressive therapy, including corticosteroids and anti-tumor necrosis factor biotherapies. Half were afebrile. Blood cultures were positive in 60% (3/5). Gallbladder histological lesions were analyzed in 3 patients and evidenced acute, chronic, or necrotic exacerbation of chronic infection. Genoserogroup of the 12 available strains were IVb (n=6), IIb (n=5), and IIa (n=1). Their survival in the bile was not enhanced when compared with isolates from other listeriosis cases. Adverse outcome was reported in 33% (5/15): 3 deaths, 1 recurrence; 75% of the patients with adverse outcome received inadequate antimicrobial therapy (P=0.033).Biliary tract listeriosis is a severe infection associated with high mortality in patients not treated with appropriate therapy. This study provides medical relevance to in vitro and animal studies that had shown Listeria monocytogenes ability to survive in bile and induce overt biliary infections. PMID:25319439

    In a prospective, randomized, multicenter study, the efficacy and safety of cefoperazone and the combination ampicillin-tobramycin as initial therapy for patients with severe acute biliary tract infections were compared. Of 77 patients initially entered in the study, definite severe biliary tract infection was confirmed in 67. Sixty-four patients completed treatment. At the end of treatment, 35 of 36 (97%) patients given cefoperazone and 23 of 28 (82%) given ampicillin-tobramycin were cured of their infection (P = 0.07). Pathogens were recovered from the bile in 32 patients; microbiological cures were observed in 18 of 19 (94%) patients receiving cefoperazone and 8 of 13 (62%) receiving ampicillin-tobramycin (P = 0.03). Thirteen patients had septicemia. None (0%) of the eight septicemic patients from the cefoperazone group, but two of five (40%) from the ampicillin-tobramycin group, were clinical failures. Of the isolated pathogens, 51% were resistant to ampicillin, while the resistance rate was 4% for tobramycin and 1% for cefoperazone (P less than 0.001). Biliary concentrations of cefoperazone were maintained at high levels--236 +/- 87 micrograms/ml up to 12 h after administration. Even in the presence of severe obstruction, cefoperazone levels in the bile and gallbladder wall were above MICs for most pathogens. Cefoperazone may be considered as an excellent alternative in the therapy of severe biliary tract infections. PMID:3056255

    Mixed adenoneuroendocrine carcinomas (MANECs) of the biliary tract are rare tumors, and to date only a few cases arising in the gallbladder have been reported. Their histogenesis is a matter of debate, since the biliary tract normally lacks neuroendocrine cells. However, the immunohistochemical identification of nonneoplastic neuroendocrine cells in both biliary adenocarcinomas and intestinal metaplasia has been documented. Here we report a case of a 55-year-old female patient presenting with right upper quadrant pain, cholelithiasis, and a gallbladder mass identified after cholecystectomy. The histopathologic examination showed a MANEC, composed of an intestinal-type adenocarcinoma and a large cell neuroendocrine carcinoma, arising in a background of enteric metaplasia with extensive high-grade dysplasia. Moreover, we report the presence of focal pancreatic intraepithelial neoplasia-like epithelial lesions, which has not been described for these tumors yet. The histopathologic features of this case provide further support for the theory that MANECs arise following a metaplasia-dysplasia-carcinoma pathway. PMID:25838330

    Biliary atresia is the most common cause of pediatric end-stage liver disease and the leading indication for pediatric liver transplantation. Affected infants exhibit evidence of biliary obstruction within the first few weeks after birth. Early diagnosis and successful surgical drainage of bile are associated with greater survival with the child’s native liver. Unfortunately, because noncholestatic jaundice is extremely common in early infancy, it is difficult to identify the rare infant with cholestatic jaundice who has biliary atresia. Hence, the need for timely diagnosis of this disease warrants a discussion of the feasibility of screening for biliary atresia to improve outcomes. Herein, newborn screening for biliary atresia in the United States is assessed by using criteria established by the Discretionary Advisory Committee on Heritable Disorders in Newborns and Children. Published analyses indicate that newborn screening for biliary atresia by using serum bilirubin concentrations or stool color cards is potentially life-saving and cost-effective. Further studies are necessary to evaluate the feasibility, effectiveness, and costs of potential screening strategies for early identification of biliary atresia in the United States. PMID:26620065

    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

    Obstructive biliary jaundice is a common complication in patients with malignancies which infiltrate biliary ducts. If untreated efficiently the jaundice is fatal a short period of time. We present a case of 60-year-old male patient who had undergone Whipple procedure in the past and presented with local recurrence treated successfully by percutaneous stenting of obstructed biliary duct. When passing through the obstruction we observed a contrast-bile leakage at the level of occluded segment and instability of implanted stent which was a complication that extorted atypical approach. We applied a covered stent in association with oversized nitinol stent which allowed to form a funnel-like construction efficiently decompressing biliary tree. Thanks to this management we also avoided further complications. PMID:23276050

    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

    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.

    Biliary cystadenoma is a rare cystic neoplasms of liver that usually occurs in middle-aged women characterized by multiloculated cysts with internal septae and mural nodules. Unilocular biliary cystadenomas are rare and are difficult to differentiate from other cysts by radiology. Biliary cystadenomas are slow growing benign lesions that are easily resectable with a reported recurrence rate of 90% when the resection is incomplete. We present a case of 65-year-old male with unilocular biliary cystadenoma with mesenchymal stroma who presented with abdominal pain and distension. Laparotomy followed by cystectomy was done and postoperative period was uneventful with no abnormal biochemical, heamatological or imaging findings. Preoperative radio-imaging techniques may not always be helpful in arriving at a specific diagnosis in such cases. Hence thorough sampling and a careful histopathological examination is considered gold standard for specific diagnosis. PMID:27042478

    Differentiation between complicated cholecystitis and advanced gallbladder carcinoma can be difficult when clinical findings are confusing. Computed tomographic (CT) scans were reviewed from 22 patients with a surgical diagnosis of complicated cholecystitis (11 cases) or advanced gallbladder carcinoma (11 cases). The presence of a curvilinear low-attenuation halo around the gallbladder wall was specific for complicated cholecystitis. Findings indicative of gallbladder carcinoma included a focal soft-invasion or metastases. Knowledge of these differential CT findings may result in a more accurate preoperative diagnosis.

    Gallbladder perforation is a potentially life-threatening condition commonly seen as a complication of acute cholecystitis. Urgent surgical intervention is often needed to reduce serious morbidity and mortality. It presents a diagnostic challenge due to nonspecific symptoms, leading to a delay in diagnosis. Imaging plays a vital role in early identification of this potentially fatal condition and evaluation by more than one imaging modality may be required to make the diagnosis. Knowledge of specific and ancillary imaging findings is crucial to avoid misdiagnosis. In this article, we will review the risk factors, pathophysiology, and surgical classification of gallbladder perforation and discuss the role of multimodality imaging in its diagnosis. Differential diagnoses on imaging will also be discussed. PMID:24627043

    Gallbladder (GB) melanoma is a rare entity with a dismal prognosis. Its primary or secondary status is difficult to establish in the absence of an overt cutaneous localization. We report herein the case of a misdiagnosed GB melanoma mimicking acute acalculous cholecystitis that was treated by means of laparoscopic cholecystectomy (LC). A 54-year-old man was referred to our institution for acute cholecystitis. Apart from the ablation of some nevocytic nevi 7 years before admission, the patient's medical history was unremarkable. The ultrasound (US) examination showed a slightly enlarged acalculous gallbladder with thickened walls and a well-circumscribed polypoid mass in the fundus. The patient was treated medically and referred to LC. At surgery, some satellite nodules were visualized in the GB hepatic bed. The GB was removed, and two hepatic nodules were excised. Histology showed a pT3 melanoma. The patient underwent an open hepatic wedge resection 3 weeks after laparoscopy. No recurrence was observed at 6-month follow-up. To date, only one case of melanoma of the gallbladder treated with LC has been reported. GB melanoma is a diagnostic challenge when there is no evidence of a primary lesion. However, the occurrence of acalculous cholecystitis and a GB polyp in patients with a positive history of mole ablation should alert surgeons to the possibility of a melanoma. PMID:11265063

    A cell strain (FU-GBC-1) was established from cancerous ascites of a 68-year-old male patient with well-differentiated adenocarcinoma of the gallbladder. By light and electron microscopy, the cultured cells showed the morphologic features of adenocarcinoma characterized by gland-like structures, intracellular microcystic spaces, and mucous production. Immunoperoxidase stains showed that FU-GBC-1 cells expressed several epithelial tumor antigens including CA 19-9, carcinoembryonic antigen (CEA), and epithelial membrane antigen (EMA). The cell strain has been in continuous culture up to passage 44 for 1 1/2 years, with the population doubling time of 120 hours. The cytogenetic analysis by a G-band technique showed a constant loss of chromosome Y in FU-GBC-1 cells. The modal chromosome number at passage 12 was 82 with a range of 77 to 85. Flow cytometry with an ethidium bromide technique additionally confirmed aneuploid DNA content (4C) in the cultured cells at passage 12 and 35. Inoculation of FU-GBC-1 cells into the dermis of BALB/c nude mice produced transplantable adenocarcinoma identical to the original tumor. Because no continuous cell lines of the well-differentiated type of gallbladder adenocarcinoma have been reported in the literature currently, the newly established cell strain we report may yield a useful system for studying the morphologic and biologic characteristics of gallbladder adenocarcinoma.

    Aging is characterized by a diminished homeostatic regulation of physiologic functions, including slowing of gastric emptying. Gastric and small intestinal motor and humoral mechanisms in humans are complex and highly variable: ingested food is stored, mixed with digestive enzymes, ground into small particles, and delivered as a liquefied form into the duodenum at a rate allowing efficient digestion and absorption. In healthy aging, motor function is well preserved whereas deficits in sensory function are more apparent. The effects of aging on gastric emptying are relevant to the absorption of oral medications and the regulation of appetite, postprandial glycemia, and blood pressure. PMID:26195094

    Few cases of neuroendocrine carcinoma (NEC) of the gallbladder (GB-NEC) have been reported. Data obtained from the 10 patients with GB-NEC treated in our hospital between January 2008 and December 2012 were retrospectively analyzed and compared with those of 377 patients with gallbladder adenocarcinoma. GB-NEC accounted for 2.2% of all gallbladder cancers. The patients (8 females and 2 males) were 59.0 ± 10.0 years old. Four patients presented mixed adenocarcinoma, while six had pure NEC. Immunohistochemical examinations showed a positive rate of 100% for CgA, NSE, and CK; the positive rates for Syn, EMA, and CD56 were 88.9, 87.5, and 75%, respectively. TNM grades II, IVA, and IVB were found in 1, 2, and 7 patients, respectively. GB-NEC patients showed significantly higher N2 lymphatic metastasis rates than gallbladder adenocarcinoma patients (70.0 vs. 34.0%; P < 0.05). Two patients were treated with radical resection and the remaining 8 with palliative operation. The 1-, 2-, and 3-year survival rates were 20, 10, and 0%, respectively (median survival time, 3.0 m); the 1-, 2-, 3-, and 5-year survival rates for all gallbladder adenocarcinoma patients were 38.0, 31.0, 30.1, and 28.4%, respectively (median survival time, 6.0 m), the difference was statistically significant (P = 0.038). The results demonstrate that GB-NEC was mainly found in aged females and shows high malignancy. Its prognosis is poorer than that of gallbladder adenocarcinoma, and surgical resection combined with TACE, radiotherapy, and chemotherapy could increase patient survival. PMID:26339390

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

    Background: Biliary tract cancers (BTCs) are rare and heterogeneous group of tumors classified anatomically into intrahepatic and extrahepatic bile ducts and gallbladder adenocarcinomas. Patient-derived tumor cell (PDC) models with genome analysis can be a valuable platform to develop a method to overcome the clinical barrier on BTCs. Material and Methods: Between January 2012 and June 2015, 40 BTC patients’ samples were collected. PDCs were isolated and cultured from surgical specimens, biopsy tissues, or malignant effusions including ascites and pleural fluid. Genome analysis using targeted panel sequencing as well as digital multiplexed gene analysis was applied to PDCs as well as primary tumors. Results: Extrahepatic cholangiocarcinoma (N = 15, 37.5%), intrahepatic cholangiocarcinoma (N = 10, 25.0%), gallbladder cancer (N = 14, 35.0%), and ampulla of Vater cancer (N = 1, 2.5%) were included. We identified 15 mutations with diverse genetic alterations in 19 cases of BTC from primary tumor specimens. The most common molecular alterations were in TP53 (8/19, 42.1%), including missense mutations such as C242Y, E285K, G112S, P19T, R148T, R248Q, and R273L. We also detected two NRAS mutations (G12C and Q61L), two KRAS mutations (G12A and G12S), two ERBB2 mutations (V777L and pM774delinsMA) and amplification, and three PIK3CA mutations (N345K, E545K, and E521K). PDC models were successfully established in 27 of 40 samples (67.5%), including 22/24 from body fluids (91.7%) and 5/16 from tissue specimens (31.3%). Conclusions: PDC models are promising tools for uncovering driver mutations and identifying rational therapeutic strategies in BTC. Application of this model is expected to inform clinical trials of drugs for molecular-based targeted therapy.

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

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