    Abstract Intra luminal gallbladder bleeding is a rare cause of hemobilia that results in upper gastro-intestinal bleeding. In this case report we present a patient who presented with melena and eventually was diagnosed as bleeding from an ulcer in the gallbladder which was induced by gallstones and eroded into the cystic artery. Surgery revealed perforation of gallbladder which was the result of a pressure sore induced by a second gallstone.

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

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

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

    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.

  18. An experimental study of gallbladder sclerosis with 10% phenol in rabbits

    International Nuclear Information System (INIS)

    To evaluate a new reliable sclerosant of the gallbladder, we attempted gallbladder ablation with 10% phenol, and the results compared with those from using 95% ethanol which had been used previous as gallbladder sclerosing agent in laboratory animals in other reports. After laparotomy, ligation of the cystic ducts with silk and cannulation of gallbladder with 18 gauge angiocatheter were done. Then, transcatheter administration of two different sclerosing agents was performed in 8 rabbits respectively and normal saline in four rabbits as a control. Additionally, preliminary washing with each agent were implement to prevent the dilutional effect of residual bile and bleeding. All animals survived without complication. Eight animals were used for each agent, four each being sacrificed two weeks and six weeks after administration of sclerosing agents respectively. In our results, 10% phenol was more effective than 95% ethanol in denuding the gallbladder epithelium and promoting fibrosis of gallbladder wall. And it was relatively safe in regard to the dilutional effect of residual fluid and bleeding during procedure. Toxic effects on the liver evaluated by examination of histologic specimen were non-specific except for edematous swelling on some case, which had also been observed on others including control group. 10% phenol can be considered to be a promising sclerosant for gallbladder ablation, but further study of its toxicity is needed before its application on human gallbladder

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

  3. Ultrasonographic Findings of Gallbladder Carcinoma

    International Nuclear Information System (INIS)

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

    In the Digestive Disease Week in 2015 there have been some new contributions in the field of gastrointestinal bleeding that deserve to be highlighted. Treatment of celecoxib with a proton pump inhibitor is safer than treatment with nonselective NSAID and a proton pump inhibitor in high risk gastrointestinal and cardiovascular patients who mostly also take acetylsalicylic acid. Several studies confirm the need to restart the antiplatelet or anticoagulant therapy at an early stage after a gastrointestinal hemorrhage. The need for urgent endoscopy before 6-12 h after the onset of upper gastrointestinal bleeding episode may be beneficial in patients with hemodynamic instability and high risk for comorbidity. It is confirmed that in Western but not in Japanese populations, gastrointestinal bleeding episodes admitted to hospital during weekend days are associated with a worse prognosis associated with delays in the clinical management of the events. The strategy of a restrictive policy on blood transfusions during an upper GI bleeding event has been challenged. Several studies have shown the benefit of identifying the bleeding vessel in non varicose underlying gastric lesions by Doppler ultrasound which allows direct endoscopic therapy in the patient with upper GI bleeding. Finally, it has been reported that lower gastrointestinal bleeding diverticula band ligation or hemoclipping are both safe and have the same long-term outcomes. PMID:26520197

    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

  12. Gallbladder function in diabetic patients

    International Nuclear Information System (INIS)

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

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

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

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

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

    Abstract Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered.

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

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

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

    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

  7. Effects of peptide YY on gallbladder motility

    International Nuclear Information System (INIS)

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

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

    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

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

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

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

    1994-08-01

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

    Acute gastrointestinal bleeding is a common major emergency (Internal medical or gastroenterological or medical), approximately 85 % of which occur in the upper GI tract. It is estimated that about a half of upper GI bleeds are caused by peptic ulcers. Upper GI bleeds are associated with more severe bleeding and poorer outcomes when compared to middle or lower GI bleeds. Prognostic determinants include bleeding intensity, patient age, comorbid conditions and the concomitant use of anticoagulants. A focused medical history can offer insight into the bleeding intensity, location and potential cause (along with early risk stratification). Initial measures should focus on rapid assessment and resuscitation of unstable patients. The oesophagogastroduodenoscopy (OGD) is the gold standard method for localizing the source of bleeding and for interventional therapy. Bleeding as a result of peptic ulcers is treated endoscopically with mechanical and / or thermal techniques in combination with proton pump inhibitor (PPI) therapy. When variceal bleeding is suspected, pre-interventional use of vasopressin analogues and antibiotic therapies are recommended. Endoscopically, the first line treatment of esophageal varices is endoscopic ligature therapy, whereas that for gastric varices is the use of Histoacryl injection sclerotherapy. When persistent and continued massive hemorrhage occurs in a patient with known or suspected aortic disease the possibility of an aorto-enteric fistula must be considered. PMID:27078246

    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

    Nonvariceal upper gastrointestinal bleeding (NUGB) remains a major medical problem even after advances in medical therapy with gastric acid suppression and cyclooxygenase (COX-2) inhibitors. Although the incidence of upper gastrointestinal bleeding presenting to the emergency room has slightly decreased, similar decreases in overall mortality and rebleeding rate have not been experienced over the last few decades. Many causes of upper gastrointestinal bleeding have been identified and will be reviewed. Endoscopic, radiographic and angiographic modalities continue to form the basis of the diagnosis of upper gastrointestinal bleeding with new research in the field of CT angiography to diagnose gastrointestinal bleeding. Endoscopic and angiographic treatment modalities will be highlighted, emphasizing a multi-modality treatment plan for upper gastrointestinal bleeding. (orig.)

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

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

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

  12. Interventional procedures in the gallbladder

    International Nuclear Information System (INIS)

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

    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.

  14. Arachidonate metabolism in bovine gallbladder muscle

    International Nuclear Information System (INIS)

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

    Full Text Available Managing a bleeding patient is very challenging for the perioperative physician. Bleeding in a patient would be due to inherited or acquired disorders of haemostasis. Identifying the patients at risk of bleeding and utilising prophylactic treatment protocols has good outcomes. Along with clinical signs, trends in monitoring coagulation parameters and analysing blood picture are necessary. Management of patients in the postoperative period and in intensive care unit should be focused on normalization of coagulation profile as early as possible with available blood and its products. Available recombinant factors should be given priority as per the approved indications. Exploring the surgical site should be considered for persistent bleeding because haemodynamic compromise, excessive transfusion of fluids, blood and its products and more inotropic support may have a negative impact on the patient outcome.

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

    A schwannoma of the gallbladder is an extremely rare tumor. We report a case of a 45-year-old woman with a polypoid mass in her gallbladder. The mass was discovered incidentally as a heterogeneous enhancing mass in the infundibulum of the gallbladder on an abdominal CT scan performed during an evaluation of a reported nonspecific left lower abdominal pain. An ultrasonography revealed that the overlying mucosa of gallbladder was intact. Moreover, a laparoscopic cholecystectomy was performed and the mass was confirmed as a gallbladder schwannoma

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

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

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

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

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

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

    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

    First trimester bleeding is a common presentation in the emergency room. Ultrasound evaluation of patients with first trimester bleeding is the mainstay of the examination. The important causes of first trimester bleeding include spontaneous abortion, ectopic pregnancy, and gestational trophoblastic disease; 50% to 70% of spontaneous abortions are due to genetic abnormalities. In normal pregnancy, the serum beta hCG doubles or increases by at least 66% in 48 hours. The intrauterine GS should be visualized by TVUS with beta hCG levels between 1000 to 2000 mIU/mL IRP. Visualization of the yolk sac within the gestational sac is definitive evidence of intrauterine pregnancy. Embryonic cardiac activity can be identified with CRL of >5 mm. A GS with a mean sac diameter (MSD) of 8 mm or more without a yolk sac and a GS with an MSD of 16 mm or more without an embryo, are important predictors of a nonviable gestation. A GS with a mean sac diameter of 16 mm or more (TVUS) without an embryo is a sonographic sign of anembryonic gestation. A difference of subchorionic hematoma. The presence of an extra ovarian adnexal mass is the most common sonographic finding in ectopic pregnancy. Other findings include the tubal ring sign and hemorrhage. About 26% of ectopic pregnancies have normal pelvic sonograms on TVUS. Complete hydatidiform mole presents with a complex intrauterine mass with multiple anechoic areas of varying sizes (Snowstorm appearance). Twenty-five percent to 65% of molar pregnancies have associated theca-leutin cysts. Arteriovenous malformation of the uterus is a rare but life-threatening cause of vaginal bleeding in the first trimester. The sonographic findings in a patient with first trimester bleeding should be correlated with serum beta hCG levels to arrive at an appropriate clinical diagnosis. PMID:15905817

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

  2. Gallbladder emptying with ceruletide in oral cholecystography

    International Nuclear Information System (INIS)

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

    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

    Inverse estimation of biomechanical parameters of soft tissues from non-invasive measurements has clinical significance in patient-specific modelling and disease diagnosis. In this paper, we propose a fully nonlinear approach to estimate the mechanical properties of the human gallbladder wall muscles from in vivo ultrasound images. The iteration method consists of a forward approach, in which the constitutive equation is based on a modified Hozapfel–Gasser–Ogden law initially developed for ar...

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

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

    2010-01-01

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

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

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

    International Nuclear Information System (INIS)

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

    Cyclic or irregular uterine bleeding is common in perimenarchal and perimenopausal women with or without endometrial hyperplasia. The disturbance often requires surgical treatment because of its negative effects on both blood loss and abnormal endometrial growth including the development of endometrial cancer. The endometrium is often overstimulated during the perimenopausal period when estrogen/progesterone production is unbalanced. A therapeutical approach with gonadotropin-releasing hormone agonist (GnRHa) was proposed in a depot formulation (Zoladex) that induces a sustained and reversible ovarian suppression. To avoid the risk of osteoporosis and to obtain adequate endometrial proliferation and differentiation during ovarian suppression, transdermal 17-beta-estradiol and oral progestin were administered. Results of 20 cases versus 20 controls showed a reduction of metrorrhagia, a normalization of hemoglobin plasma concentration, and an adequate proliferation and secretory differentiation of the endometrium of patients with abnormal endometrial growth. Abnormal uterine bleeding is mainly due to uterine fibrosis and an inadequate estrogen and/or progesterone production or to a disordered estrogen transport from blood into the endometrium. In premenopausal women, endometrial hyperplasia may be part of a continuum that is ultimately manifested in the histological and biological pattern of endometrial carcinoma. The regression of endometrial hyperplasia obtained by using the therapeutic regimen mentioned above represents a preventive measure for endometrial cancer. Finally the normalization of blood loss offers a good medical alternative to surgery for patients with DUB. PMID:7978956

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

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

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

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

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

    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.

  12. Early Diagnosis of Gallbladder Carcinoma: An Algorithm Approach

    International Nuclear Information System (INIS)

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

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

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

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

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

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

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

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

    2014-01-01

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

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

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

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

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

    Wong, K; Ekberg, O; Laufer, I; Malet, P F; Arger, P

    1990-01-01

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

    2009-03-01

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

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

    Full Text Available Diverticular hemorrhage is the most common reason for lower gastrointestinal bleeding (LGIB with substantial cost of hospitalization and a median length of hospital stay of 3 days. Bleeding usually is self-limited in 70–80% of cases but early rebleeding is not an uncommon problem that can be reduced with proper endoscopic therapies. Colonoscopy is recommended as first-line diagnostic and therapeutic approach. In the vast majority of patients diverticular hemorrhage can be readily managed by interventional endotherapy including injection, heat cautery, clip placement, and ligation to achieve endoscopic hemostasis. This review will serve to highlight the various interventions available to endoscopists with specific emphasis on superior modalities in the endoscopic management of diverticular bleeding.

    Direct oral anticoagulants (DOAC) are recommended for stroke prevention in atrial fibrillation and for the treatment of venous thromboembolism. However, they are associated with hemorrhagic complications. Management of DOAC-induced bleeding remains challenging. Activated or non-activated prothrombin concentrates are proposed, although their efficacy to reverse DOAC is uncertain. Therapeutic options also include antidotes: idarucizumab, antidote for dabigatran, has been approved for use whereas andexanet alpha, antidote for anti-Xa agents, and aripazine, antidote for all DOAC, are under development. Other options include hemodialysis for the treatment of dabigatran-associated bleeding and administration of oral charcoal if recent DOAC ingestion. DOAC plasma concentration measurement is necessary to guide DOAC reversal. We propose an update on DOAC-associated bleeding, integrating the availability of dabigatran antidote and the critical place of DOAC concentration measurements. PMID:27297642

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

Immunohistochemical analysis of the surgical specimen of the cholecystectomy revealed pancreatic tissue at the gallbladder wall. Conclusions Heterotopic pancreatic tissue is a rare pathological finding in the gallbladder. It requires consideration and sensitization in the differential diagnosis of acalculous gallbladder disease, which can explain hyperamylasuria in cases of unknown origin.

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

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

    International Nuclear Information System (INIS)

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

    Full Text Available A 10-year-old girl presented with recurrent right upper abdominal pain and dyspepsia. Magnetic resonance cholangiopancreatography revealed a dilated common channel of intrahepatic bile duct of segment 3 (B3 and segment 4 (B4 drained into the gallbladder directly. The patient underwent laparoscopic cholecystectomy and Roux-en Y hepaticojejunostomy (B3-jejunostomy. Among the anatomical variability of the biliary system, the cholecystohepatic ducts are controversial in existence and incidence. We report a very rare variant of a cholecystohepatic duct in which the B3 duct drained into gallbladder directly and to the best of our knowledge this is the first report.

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

    International Nuclear Information System (INIS)

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

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

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

    1988-05-01

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

    BACKGROUND Calciphylaxis is associated with a high mortality that approaches 80%. The diagnosis is usually made when obvious skin lesions (painful violaceous mottling of the skin) are present. However, visceral involvement is rare. We present a case of calciphylaxis leading to lower gastrointestinal (GI) bleeding and rectal ulceration of the GI mucosa. CASE REPORT A 66-year-old woman with past medical history of diabetes mellitus, hypertension, end-stage renal disease (ESRD), recently diagnosed ovarian cancer, and on hemodialysis (HD) presented with painful black necrotic eschar on both legs. The radiograph of the legs demonstrated extensive calcification of the lower extremity arteries. The hospital course was complicated with lower GI bleeding. A CT scan of the abdomen revealed severe circumferential calcification of the abdominal aorta, celiac artery, and superior and inferior mesenteric arteries and their branches. Colonoscopy revealed severe rectal necrosis. She was deemed to be a poor surgical candidate due to comorbidities and presence of extensive vascular calcifications. Recurrent episodes of profuse GI bleeding were managed conservatively with blood transfusion as needed. Following her diagnosis of calciphylaxis, supplementation with vitamin D and calcium containing phosphate binders was stopped. She was started on daily hemodialysis with low calcium dialysate bath as well as intravenous sodium thiosulphate. The clinical condition of the patient deteriorated. The patient died secondary to multiorgan failure. CONCLUSIONS Calciphylaxis leading to intestinal ischemia/perforation should be considered in the differential diagnosis in ESRD on HD presenting with abdominal pain or GI bleeding. PMID:26572938

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

    2011-04-01

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

  1. Sonographic and cholecystographic diagnosis of cholesterolosis of the gallbladder

    International Nuclear Information System (INIS)

    Cholesterolosis is difficult to detect preoperatively. Ultrasonography can reveal it as polypoid densities usually without shadows. Cholecystography reveals cholesterolosis as contrast medium defects attached to the gallbladder wall. In our material of 27 patients with cholesterolosis (operatively verified cases) ultrasonography was superior to cholecystography in detecting cholesterolosis. (orig.)

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

    International Nuclear Information System (INIS)

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

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

    CONCLUSION: A giant gallbladder is a special clinical and pathological entity in surgical practice, of unknown origin. It may develop in patients of any age, and mimics a large abdominal tumour or peritoneal cyst. Both the diagnostic process and surgical treatment demand non-routine approaches. Early and late follow-up results seem to be favourable.

    Obscure gastrointestinal bleeding (OGIB) is defined as bleeding of an unknown origin that persists or recurs after negative initial upper and lower endoscopies.Several techniques,such as endoscopy,arteriography,scintigraphy and barium radiology are helpful for recognizing the bleeding source;nevertheless,in about 5%-10% of cases the bleeding lesion cannot be determined.The development of videocapsule endoscopy (VCE) has permitted a direct visualization of the small intestine mucosa.We will analyze those techniques in more detail.The diagnostic yield of CE for OGIB varies from 38% to 93%,being in the higher range in those cases with obscure-overt bleeding.

Active bleedings and/or vascular lesions were identified in 16 patients. They were proved by antiography, endoscopy or barium enema in 14. We concluded that scintigraphy was an accurate and effective method to detect the bleeding and determine the bleeding site in the lower gastrointestinal tract. (author)

    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 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

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

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

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

    International Nuclear Information System (INIS)

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

  2. Oral cholecystography vs gallbladder sonography: a prospective, blinded reappraisal.

    1988-07-01

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

  3. Gallbladder disease in patients with primary sclerosing cholangitis

    International Nuclear Information System (INIS)

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

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

  6. Bleeding complications of femoral catheterization

    International Nuclear Information System (INIS)

    CT has been used to evaluate hematomas resulting from femoral catheterization (percutaneous transluminal coronary angioplasty, cardiac catheterization, angioplasty, valvuloplasty, and venous access) in 21 patients. Four distinct types of hematoma have been identified: retroperitoneal (N = 12); intraperitoneal (N = 3); groin/thigh (N = 9); and abdominal wall (N = 5). Seven patients had hematomas in two locations. CT contributed by estimating transfusion requirement, indicating the need for more intensive monitoring, and predicting the potential need for surgery. Type 1 and 2 bleeds were the most serious and had the most sequelae. Sequelae included transfusion in 17 patients (mean, 5 units/patient) and surgery in two patients

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

    This communication deals with the emergency control of variceal bleeding rather than the prevention of rebleeding. The current main options of oesophageal tamponade, emergency sclerotherapy and drug therapy are discussed, with particular reference to the use of somatostatin. Sandostatin (Sandoz, Basel), a synthetic long-acting somatostatin analogue, was found to reduce transhepatic venous gradient by 30% with no effect on systemic haemodynamics in a study of 16 stable cirrhotic patients. In a trial comparing intravenous infusion of Sandostatin (SMS) to oesophageal tamponade (OT) in active variceal bleeding, 18 of 20 bleeds in the SMS group and 19 of 20 bleeds in the OT group were controlled at 4 h. Ten in the SMS group and 14 in the OT group had no further bleeding during the 48-hour study period. Thus SMS may be useful in the temporary control of active variceal bleeding. PMID:8359565

    Three case reports of cyclical rectal bleeding in endometriosis affecting rectum and sigmoid colon emphasize the close relationship between such cyclical bleeding and intestinal endometriosis. The cause of bleeding, however, is still unclear. The predilection of endometriotic deposits for the outer layers of the bowel wall suggests that mucosal involvement is not a prerequisite for rectal bleeding. The frequent absence of identifiable intramural haemorrhage casts doubt on the premise that intestinal endometriotic deposits 'menstruate'. The cause may simply be a transient tear in normal mucosa due to swelling of an underlying endometriotic deposit at the time of menstruation. PMID:2597100

    Bleed condenser, a vertical, tube and shell type heat exchanger employed in bleed circuit of primary heat transport system of PHWR is used for condensing the flashing bleed (heavy water) on shell side and cold heavy water on the tubes side. Examinations conducted at various places indicate failure due to inadequate tube expansion (hydraulic expansion) followed by crevice corrosion. Mechanical rolling of tubes to larger extent (3 to 6% wall thinning) have been specified for this particular type of service in all bleed condensers for subsequent projects. 1 tab., 4 figs

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

    International Nuclear Information System (INIS)

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

  15. Diagnostic Strategies for Postmenopausal Bleeding

    2010-01-01

    Full Text Available Postmenopausal bleeding (PMB is a common clinical problem. Patients with PMB have 10%–15% chance of having endometrial carcinoma and therefore the diagnostic workup is aimed at excluding malignancy. Patient characteristics can alter the probability of having endometrial carcinoma in patients with PMB; in certain groups of patients the incidence has been reported to be as high as 29%. Transvaginal sonography (TVS is used as a first step in the diagnostic workup, but different authors have come to different conclusions assessing the accuracy of TVS for excluding endometrial carcinoma. Diagnostic procedures obtaining material for histological assessment (e.g., dilatation and curettage, hysteroscopy, and endometrial biopsy can be more accurate but are also more invasive. The best diagnostic strategy for diagnosing endometrial carcinoma in patients with PMB still remains controversial. Future research should be focussed on achieving a higher accuracy of different diagnostic strategies.

    2015-05-01

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

    2016-08-15

    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.

    Adolescents with bleeding disorders who become pregnant must contend with the dual challenges of their bleeding disorder and their pregnancy. Adolescents are more likely to terminate a pregnancy than adult women, and when they do carry a pregnancy, they are more likely to deliver prematurely. Otherwise, they are at risk for the same complications that adult women with bleeding disorders experience, particularly bleeding complications postpartum. Since one half to two thirds of adolescent pregnancies are unplanned, issues related to reproduction should be addressed during routine visits with the pediatrician, hematologist or gynecologist. Girls who are at risk of being carriers for hemophilia A and B, severe von Willebrand disease, and other severe bleeding disorders should have their bleeding disorder status determined before they become pregnant. During pregnancy, a plan should be established to ensure that both mother and fetus deliver safely. Young women at risk for severe bleeding or at risk of having a severely affected infant should be referred for prenatal care and delivery to a center where, in addition to specialists in high-risk obstetrics, there is a hemophilia treatment center or a hematologist with expertise in hemostasis. Prior to delivery or any invasive procedures, young women at risk for severe bleeding should receive prophylaxis. Since administration of desmopressin may result in hyponatremia, whenever available, virally inactivated or recombinant clotting factor concentrates should be used for replacement as opposed to fresh frozen plasma or cryoprecipitate.

    Gallbladder localization of heterotopic pancreas (HP)is uncommon and very rarely gives rise to symptoms.Herein we report a case of HP found in the gallbladder neck presented with signs and symptoms of cholecystitis.The patient was a 40-year old male, suffering from epigastric pain, abdominal fullness and fever. On physical examination, the right upper abdomen was tender with a positive Murphy's sign. Ultrasonographic examination showed a hydropic gallbladder without stones and he underwent a cholecystectomy. Pathological examination revealed an intramural nodule (9 mm) in the neck region which is consisted of acini, ducts and islet cells of an aberrant pancreatic tissue. Although HP is encountered rarely in the gallbladder and is found incidentally durng pathological studies, this case emphasizes that HP might cause symptoms and present clinically as cholecystitis.For this reason, in patients presenting with symptomatic gallbladder diseases, including cholecystitis without any other pathology, HP should be taken into consideration before it is diagnosed as "idiopathic".

    Full Text Available Abstract Background Gallbladder perforation is a rare clinical condition, which mostly occurs following acute cholecystitis associated with cholelithiasis. A tumor of the ampulla of Vater causes gradually progressive symptoms, and is rarely associated with perforation of the gallbladder. Case Presentation A 56-year-old man with carcinoma of the ampulla of Vater presented with spontaneous gallbladder perforation and localized bile peritonitis. He complained of right upper abdominal pain, and laparotomy revealed perforation of the gallbladder with no gallstones. Postoperative upper gastrointestinal endoscopy demonstrated a slightly enlarged duodenal papilla, and biopsy revealed adenocarcinoma of the ampulla. Pylorus-preserving pancreaticoduodenectomy was performed subsequently. Conclusion Ampullary carcinoma can be associated with gallbladder perforation and present with acute manifestations. Immediate surgical treatment is required for this condition.

    AIM: To study whether H pylori locate in the gallbladder mucosa of patients with chronic cholecystitis.METHODS: Using Warthy-Starry (W-S) silver stain and immunohistochemistry stain with anti-H pylori antibodies, we screened paraffin specimens in 524 cases of cholecystitis. H pylori urease gene A (HPUA) and H pylori urease gene B (HPUB) were analyzed by polymerase chain reaction (PCR) in the fresh tissue specimens from 81 cases of cholecystitis.RESULTS: H pylori-like bacteria were found in 13.55% of the gallbladders of the cholecystitis patients using W-S stain. Meanwhile, bacteria positive for H pylori antibodies were also found in 7.1% of the gallbladders of patients with cholecystitis by immunohistochemistry. Of 81 gallbladders, 11 were positive for both HPUA and HPUB, 4 were positive for HPUA only and 7 were positive for HPUB only.CONCLUSION: H pylori exist in the gallbladders of patients with chronic cholecystitis.

  7. Transient gallbladder distention in sick premature infants: The value of ultrasonography and radionuclide scintigraphy

    International Nuclear Information System (INIS)

    Transient gallbladder distention in sick premature infants has been reported with increasing frequency over the last few years. It is important to be aware of this entity of gallbladder disease which resolves spontaneously and to be able to differentiate it from other problems that require surgical correction. We believe that ultrasonography is most helpful in confirming the diagnosis, excluding stone formation, and documenting any changes in size or appearance. However, there are no reliable ultrasonic criteria for distinguishing inflamed or pathologically distended gallbladders from noninflamed or temporarily enlarged gallbladders. Radioisotope imaging, though useful in demonstrating malfunction of the hepatobiliary system, should be interpreted with caution. In the final analysis, the dilemma as to whether gallbladder distention is a transient or persistent malfunction can be settled best by thoughtful clinical judgement. (orig.)

    Full Text Available Background. The Molecular Adsorbent Recirculating System (MARS has been shown to clear albumin-bound toxins from patients with liver failure but might cause bleeding complications potentially obscuring survival benefits. We hypothesized that monitoring clotting parameters and bed-side thromboelastography allows to reduce bleeding complications. Methods. Retrospective analysis of 25 MARS sessions during which clotting parameters were monitored by a standardized protocol. Results. During MARS therapy median INR increased significantly from 1.7 to 1.9 platelet count and fibrinogen content decreased significantly from 57 fL−1 to 42 fL−1 and 2.1 g/L to 1.5 g/L. Nine relevant complications occurred: the MARS system clotted 6 times 3 times we observed hemorrhages. Absent thrombocytopenia and elevated plasma fibrinogen predicted clotting of the MARS system (ROC 0.94 and 0.82. Fibrinolysis, detected by thromboelastography, uniquely predicted bleeding events. Conclusion. Bed-side thromboelastography and close monitoring of coagulation parameters can predict and, therefore, help prevent bleeding complications during MARS therapy.

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

    Establishing a precise duration of gestation is vital in situations such as infanticide and criminal abortions. The present study attempted to estimate the gestational age of the foetus from gall-bladder length. Foetuses of various gestational age groups were dissected, and the length of the gall bladder was measured. The results were analysed, and a substantial degree of correlation was statistically confirmed. This novel method is helpful when the foetus is fragmented, putrefied or eviscerated, where this method can be used as an additional parameter to improve the accuracy of foetal age estimation.

  13. Endoscopic management of bleeding peptic ulcers

    International Nuclear Information System (INIS)

    Peptic ulcers account for more than half of the cases of non variceal upper gastrointestinal (GI) bleeding and therefore, are the focus of most of the methods of endoscopic hemostasis. Surgical intervention is now largely reserved for patients in whom endoscopic hemostasis has failed. A variety of endoscopic techniques have been employed to stop bleeding and reduce the risk of rebleeding, with no major differences in outcome between these methods. These include injection therapy, fibrin injection, heater probe, mono polar electrocautery, bipolar electrocautery, lasers and mechanical hemo clipping. The most important factor in determining outcome after gastrointestinal bleeding is rebleeding or persistent bleeding. The endoscopic appearance of an ulcer, however, provides the most useful prognostic information for bleeding. Recurrent bleeding after initial endoscopic hemostasis occurs in 15-20% of patients with a bleeding peptic ulcer. The best approach to these patients remains controversial; the current options are repeat endoscopic therapy with the same or a different technique, emergency surgery or semi elective surgery after repeat endoscopic hemostasis. The combination of epinephrine injection with thermal coagulation may be more effective than epinephrine injection alone. Newer modalities such as fibrin injection or the application of hemo clips appear promising and comparative studies are awaited. (author)

  14. Elevation of Pancreatic Enzymes in Gallbladder Bile Associated with Heterotopic Pancreas. A Case Report and Review of the Literature

    Directory of Open Access Journals (Sweden)

    Asahi Sato

    2012-03-01

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

    A compressor bleed cooling fluid feed system for a turbine engine for directing cooling fluids from a compressor to a turbine airfoil cooling system to supply cooling fluids to one or more airfoils of a rotor assembly is disclosed. The compressor bleed cooling fluid feed system may enable cooling fluids to be exhausted from a compressor exhaust plenum through a downstream compressor bleed collection chamber and into the turbine airfoil cooling system. As such, the suction created in the compressor exhaust plenum mitigates boundary layer growth along the inner surface while providing flow of cooling fluids to the turbine airfoils.

    The aim of this study was to correlate MR findings of gallbladder wall thickening with pathologic findings on the basis of the layered pattern and to evaluate the diagnostic value of MR imaging in gallbladder disease. We retrospectively evaluated the source images of HASTE sequences for MR cholangiography in 144 patients with gallbladder wall thickening. The layered pattern of thickened wall was classified into four patterns. Type 1 shows two layers with a thin hypointense inner layer and thick hyperintense outer layer. Type 2 has two layers of ill-defined margin. Type 3 shows multiple hyperintense cystic spaces in the wall. Type 4 shows diffuse nodular thickening without layering. MR findings of a layered pattern of thickened gallbladder were well correlated with histopathology. Chronic cholecystitis matched to type 1, acute cholecystitis corresponded to type 2, adenomyomatosis showed type 3, and the gallbladder carcinomas showed type 4. All four layered patterns were associated with PPV of 73% or greater, sensitivity of 92% or greater and specificity of 95% or greater. Our results indicate that MR findings of gallbladder wall thickening are characteristic in each entity and correlate well with pathologic findings. The classification of the layered pattern may be valuable for interpreting thickened gallbladder wall. (orig.)

    There is a paucity of information of tight junction (TJ) proteins in gallbladder epithelium, and disturbances in the structure of these proteins may play a role in the pathogenesis of acute acalculous cholecystitis (AAC) and acute calculous cholecystitis (ACC). Using immunohistochemistry, we investigated the expression of TJ proteins claudin-1, -2, -3, and -4, occludin, zonula occludens (ZO-1), and E-cadherin in 9 normal gallbladders, 30 gallbladders with AAC, and 21 gallbladders with ACC. The number of positive epithelial and endothelial cells and the intensity of the immunoreaction were determined. Membrane-bound and cytoplasmic immunoreactivities were separately assessed. We found that TJ proteins were uniformly expressed in normal gallbladder epithelium, with the exception of claudin-2, which was present in less than half of the cells. In AAC, expression of cytoplasmic occludin and claudin-1 were decreased, as compared with normal gallbladder. In ACC, expression of claudin-2 was increased, and expression of claudin-1, -3, and -4, occludin, and ZO-1 were decreased, as compared with normal gallbladder or AAC. We conclude that there are significant differences in expression of TJ proteins in AAC and ACC, supporting the idea that AAC represents a manifestation of systemic inflammatory disease, whereas ACC is a local inflammatory and often infectious disease.

  18. Mutational profiling reveals PIK3CA mutations in gallbladder carcinoma

    International Nuclear Information System (INIS)

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

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

    Full Text Available Abstract Background The objective of this study was to examine the extent of surgical procedures, pathological findings, complications and outcome of patients treated in the last 12 years for gallbladder cancer. Methods The impact of a standardized more aggressive approach compared with historical controls of our center with an individual approach was examined. Of 53 patients, 21 underwent resection for cure and 32 for palliation. Results Overall hospital mortality was 9% and procedure related mortality was 4%. The standardized approach in UICC stage IIa, IIb and III led to a significantly improved outcome compared to patients with an individual approach (Median survival: 14 vs. 7 months, mean+/-SEM: 26+/-7 vs. 17+/-5 months, p = 0.014. The main differences between the standardized and the individual approach were anatomical vs. atypical liver resection, performance of systematic lymph dissection of the hepaticoduodenal ligament and the resection of the common bile duct. Conclusion Anatomical liver resection, proof for bile duct infiltration and, in case of tumor invasion, radical resection and lymph dissection of the hepaticoduodenal ligament are essential to improve outcome of locally advanced gallbladder cancer.

    AIM: To study the mechanism by which Helicobacter pylori (Hpy/orO damages human gallbladder epithelial cells (HGBEC).METHODS: H pylori isolated from gallbladder were cultured in a liquid medium. Different concentration supernatants and sonicated extracts of H pylori cells were then added to HGBEC in a primary culture. The morphological changes in HGBEC as well as changes in the levels of alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and glutamyltransferase (GGT)were measured.RESULTS: According to the culture curve of HGBEC,it was convenient to study the changes in HGBEC by adding H pylori sonicated extracts and H pylori culture supernatants. Both H pylori sonicated extracts and H pylori culture supernatants had a significant influence on HGBEC morphology, i.e. HGBEC grew more slowly, their viability decreased and their detachment increased. Furthermore, HGBEC ruptured and died. The levels of ALP (33.84 ± 6.00 vs 27.01± 4.67, P < 0.05), LDH (168.37 ± 20.84 vs 55.51 ±17.17, P < 0.01) and GGT (42.01 ± 6.18 vs 25.34 ±4.33, P < 0.01) significantly increased in the HGBEC culture supernatant in a time- and concentrationdependent. The damage to HGBEC in Hpylori culture liquid was more significant than that in H pylori sonicated extracts.CONCLUSION: H pylori induces no obvious damage to HGBEC.

    Lymphangiomas are malformations of the lymphatic system,which is a common disease in children,usually superficial in body,but seldom seen in visceral organs.We present the case of a child with lymphangioma of the gallbladder.Also we reviewed the literatures.A 2-year-6-month-old boy complained of progressing difficulty in walking for 6 months.Cerebral MRI showed abnormal signals in the white matter suggesting leukodystrophy.Ultrasound of abdomen showed a mixed-echoic mass in the site of gallbladder.CT scan showed an enlarged gallbladder with increased density.Bloodcounting,liver function,and alpha fetal protein were within normal range.Exploratory laparotomy was done in order to rule out malignancy.The liver was found normal at surgery,and the gallbladder looked enlarged and deformed.The gallbladder wall was thick and edematous,and adherent with liver.The gallbladder was excised.Pathological examination gave the dia gnosis as lymphangioma of the gallbladder wall.The postoperative recovery was uneventful.There was no evidence of recurrence.Searching in literatures,three cases of lymphangioma of gallbladder in adults were found.According to the pathology of lymphangioma and the anatomy of gallbladder,the outcome of this disease should be benign and may be symptomless throughout the life.No death was reported due to lymphangioma of gall bladder,nor severe complications endangering life at any age.The only indication for surgery in the reported cases was to rule out the risk of being malignancy.If MRI or other means can make a definite preoperative diagnosis of lymphangioma,being a stable lesion,surgery would be unnecessary unless there is a progressive organic obstruction causing repeated infection or persistent abdominal pain.

    Peptic ulcers are an extremely common condition, usually occurring in the stomach and proximal duodenum. However, cases of peptic ulcers accompanied with multiple complications are extremely rare and hard to treat. The present case reinforces the requirement for the early recognition and correct treatment of peptic ulcers accompanied with multiple complications. A 67-year-old man presented with recurrent abdominal pain, fever and melena. The laboratory results showed anemia (hemoglobin 62 g/l) and hypoproteinemia (23 g/l). Abdominal imaging examinations revealed stones in the gallbladder and right liver, with air in the dilated intrahepatic and extrahepatic bile ducts. Endoscopic retrograde cholangiopancreatography failed due to a deformed pylorus. The patient was finally diagnosed with peptic ulcers accompanied with gastrointestinal (GI) bleeding, pylorus obstruction and cholangitis secondary to a choledochoduodenal fistula during an emergency pancreatoduodenectomy, which was performed due to a massive hemorrhage of the GI tract. The patient recovered well after the surgery. PMID:26870237

  4. CLSM bleed water reduction test results

    International Nuclear Information System (INIS)

    Previous testing by BSRI/SRTC/Raytheon indicated that the CLSM specified for the Tank 20 closure generates about 6 gallons (23 liters) of bleed water per cubic yard of material (0.76 m3).1 This amount to about 10 percent of the total mixing water. HLWE requested that the CLSM mix be optimized to reduce bleed water while maintaining flow. Elimination of bleed water from the CLSM mix specified for High-Level Waste Tank Closure will result in waste minimization, time savings and cost savings. Over thirty mixes were formulated and evaluated at the on-site Raytheon Test Laboratory. Improved low bleed water CLSM mixes were identified. Results are documented in this report

    Pelvic radiation disease is one of the major complication after radiotherapy for pelvic cancers. The most commonly reported symptom is rectal bleeding which affects patients' quality of life. Therapeutic strategies for rectal bleeding are generally ignored and include medical, endoscopic, and hyperbaric oxygen treatments. Most cases of radiation-induced bleeding are mild and self-limiting, and treatment is normally not indicated. In cases of clinically significant bleeding (i.e. anaemia), medical therapies, including stool softeners, sucralfate enemas, and metronidazole, should be considered as first-line treatment options. In cases of failure, endoscopic therapy, mainly represented by argon plasma coagulation and hyperbaric oxygen treatments, are valid and complementary second-line treatment strategies. Although current treatment options are not always supported by high-quality studies, patients should be reassured that treatment options exist and success is achieved in most cases if the patient is referred to a dedicated centre.

    Molecular genetic analysis of inherited bleeding disorders has been practised for over 30 years. Technological changes have enabled advances, from analyses using extragenic linked markers to next-generation DNA sequencing and microarray analysis. Two approaches for genetic analysis are described, each suiting their environment. The Christian Medical Centre in Vellore, India, uses conformation-sensitive gel electrophoresis mutation screening of multiplexed PCR products to identify candidate mutations, followed by Sanger sequencing confirmation of variants identified. Specific analyses for F8 intron 1 and 22 inversions are also undertaken. The MyLifeOurFuture US project between the American Thrombosis and Hemostasis Network, the National Hemophilia Foundation, Bloodworks Northwest and Biogen uses molecular inversion probes (MIP) to capture target exons, splice sites plus 5' and 3' sequences and to detect F8 intron 1 and 22 inversions. This allows screening for all F8 and F9 variants in one sequencing run of multiple samples (196 or 392). Sequence variants identified are subsequently confirmed by a diagnostic laboratory. After having identified variants in genes of interest through these processes, a systematic procedure determining their likely pathogenicity should be applied. Several scientific societies have prepared guidelines. Systematic analysis of the available evidence facilitates reproducible scoring of likely pathogenicity. Documentation of frequency in population databases of variant prevalence and in locus-specific mutation databases can provide initial information on likely pathogenicity. Whereas null mutations are often pathogenic, missense and splice site variants often require in silico analyses to predict likely pathogenicity and using an accepted suite of tools can help standardize their documentation.

    Recently, several reports have demonstrated that fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) is useful in differentiating between benign and mal ignant lesions in the gallbladder. However, there is a limitation in the ability of FDG-PET to differentiate between inflammatory and malignant lesions. We herein present a case of xanthogranulomatous cholecystitis misdiagnosed as gallbladder carcinoma by ultrasonography and computed tomography. FDG-PET also showed increased activity. In this case, FDG-PET findings resulted in a false-positive for the diagnosis of gallbladder carcinoma.

  14. Management of nonvariceal upper gastrointestinal bleeding

    Directory of Open Access Journals (Sweden)

    E Wee

    2011-01-01

    Full Text Available Nonvariceal upper gastrointestinal bleeding is unique from variceal bleeding in terms of patient characteristics, management, rebleeding rates, and prognosis, and should be managed differently. The majority of nonvariceal upper gastrointestinal bleeds will not rebleed once treated successfully. The incidence is 80 to 90% of all upper gastrointestinal bleeds and the mortality is between 5 to 10%. The causes include nonacid-related ulceration from tumors, infections, inflammatory disease, Mallory-Weiss tears, erosions, esophagitis, dieulafoy lesions, angiodysplasias, gastric antral vascular ectasia, and portal hypertensive gastropathy. Rarer causes include hemobilia, hemosuccus pancreaticus, and aortoenteric fistulas. Hematemesis and melena are the key features of bleeding from the upper gastrointestinal tract, but fresh per rectal bleeding may be present in a rapidly bleeding lesion. Resuscitation and stabilization before endoscopy leads to improved outcomes. Fluid resuscitation is essential to avoid hypotension. Though widely practiced, there is currently insufficient evidence to show that routine red cell transfusion is beneficial. Coagulopathy requires correction, but the optimal international normalized ratio has not been determined yet. Risk stratification scores such as the Rockall and Glasgow-Blatchford scores are useful to predict rebleeding, mortality, and to determine the urgency of endoscopy. Evidence suggests that high-dose proton pump inhibitors (PPI should be given as an infusion before endoscopy. If patients are intolerant of PPIs, histamine-2 receptor antagonists can be given, although their acid suppression is inferior. Endoscopic therapy includes thermal methods such as coaptive coagulation, argon plasma coagulation, and hemostatic clips. Four quadrant epinephrine injections combined with either thermal therapy or clipping reduces mortality. In hypoxic patients, endoscopy masks allow high-flow oxygen during upper

    Full Text Available Introduction: Male circumcision practice is an invasive procedure that is using worldwide. It makes challenges to haemostatic system and its possible haemorrhagic side effects are more serious in bleeding individuals than normal subjects. In most cases, it can be complete controlled using infusion of appropriate amount of coagulation factors before and post circumcision.Aim: We aim to documentation type of coagulation therapy and post circumcision practice haemorrhagic presentation among 463 bleeder males of both common and rare bleeding disorders in north eastern part of country.Methods: We retrospectively gathered information using evaluation medical records in 3 major hospitals during last 15 years and list of patients with bleeding disorders that obtained from haemophilia center. Also a call phone established for each bleeder person to complete data and updating of them. The survey took time from Sep 2009- Mar 2011. The designed question form included data on doing circumcision or not? types of treatment before and post the procedure and occurrence of bleeding episodes after the surgery.Results: Overall among 424 cases with various common and rare bleeding disorders who had circumcised, 239 cases (56.3% had passed the procedure with bleeding experience, while 185 cases (43.7% had passed it successfully and without noticeable bleeding experience. The types of coagulation therapy in each group have been cited.Conclusion: The circumcision practice in unequipped medical center for bleeder ones may make challenges for them and medical services. Also it needed supervision of expert haematologist for adjusting treatment to ensure control of unwanted bleeding

    Angiography is essential for the detection of bleeding vessels in traumatic vascular injury. Immediately after the diagnosis, transcatheter embolization can be performed for the control of bleeding effectively and easily with proper use of embolic materials. Transcatheter embolization is believed to be the treatment of choice when emergency control is needed, where surgical approach is difficult and in those who are poor candidate for surgery. We have tried bleeding control in 18 cases of trauma over recent 4 years. The results were as follows; 1. Causes of bleeding(cases): Blunt or penetrating trauma (10), latrogenic trauma (8), (Postoperative (5), Needle biopsy (2), Percutaneous hepatic procedure (1)) 2. Embolized vessels: Renal artery branches (8), Hepatic artery branches (2), Arteries supplying chest wall (2), External carotid artery branches (3), Internal carotid artery (1), Circumflex humeral artery (1), Internal iliac artery branches (1). 3. Embolic agents: Gelfoam cubes (16), Stainless steel coils (3), Detachable latex balloon (1). 4. Successful bleeding control was achieved in 17 cases and reduction of the amount of bleeding in one case without significant complications.

    International Nuclear Information System (INIS)

    PurposeTo assess optimal bed-rest duration after vascular intervention by way of the common femoral artery using 3F introducer sheaths.Materials and MethodsEligibility criteria for this single-center, prospective study included clinically necessary angiography, no coagulopathy or anticoagulant therapy, no hypersensitivity to contrast medium, age >20 years, and written, informed consent. Enrolled patients were assigned to one of three groups (105/group) with the duration of bed rest deceased sequentially. A sheath was inserted by way of the common femoral artery using the Seldinger technique. The first group (level 1) received 3 h of bed rest after the vascular intervention. If no bleeding or hematomas developed, the next group (level 2) received 2.5 h of bed rest. If still no bleeding or hematomas developed, the final group (level 3) received 2 h of bed rest. If any patient had bleeding or hematomas after bed rest, the study was terminated, and the bed rest of the preceding level was considered the optimal duration.ResultsA total of 105 patients were enrolled at level 1 between November 2010 and September 2011. Eight patients were excluded from analysis because cessation of bed rest was delayed. None of the remaining subjects experienced postoperative bleeding; therefore, patient enrollment at level 2 began in September 2011. However, puncture site bleeding occurred in the 52nd patient immediately after cessation of bed rest, necessitating study termination.ConclusionTo prevent bleeding, at least 3 h of postoperative bed rest is recommended for patients undergoing angiography using 3F sheaths

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

    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.

    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

  4. Cholecystokinin-Assisted Hydrodissection of the Gallbladder Fossa during FDG PET/CT-guided Liver Ablation

    International Nuclear Information System (INIS)

    A 68-year-old female with colorectal cancer developed a metachronous isolated fluorodeoxyglucose-avid (FDG-avid) segment 5/6 gallbladder fossa hepatic lesion and was referred for percutaneous ablation. Pre-procedure computed tomography (CT) images demonstrated a distended gallbladder abutting the segment 5/6 hepatic metastasis. In order to perform ablation with clear margins and avoid direct puncture and aspiration of the gallbladder, cholecystokinin was administered intravenously to stimulate gallbladder contraction before hydrodissection. Subsequently, the lesion was ablated successfully with sufficient margins, of greater than 1.0 cm, using microwave with ultrasound and FDG PET/CT guidance. The patient tolerated the procedure very well and was discharged home the next day

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

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

  13. Carcinogenesis of gallbladder mucosa with occult pancreatobiliary reflux

    International Nuclear Information System (INIS)

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

    2013-06-01

    The molecular mechanisms leading to gallbladder carcinoma (GBC) are poorly understood. Different molecular disorders, including nuclear and mitochondrial genomic alteration, are associated with different cancers. The frequency of mitochondrial genome mutation has remained completely unexplored. In GBC, this is the first report of a mutation analysis in the mitochondrial genome, especially in the D-loop region. For a comprehensive D-loop view in GBC in humans, we sequenced the mitochondrial genome of 35 GBC patients and matched germ-line DNA. A wide range of point mutations and polymorphisms was observed. These variations in the D-loop sequence of human GBC represent good evidence of the mitochondrial role in GB carcinogenesis and may be used as a marker for GBC. PMID:23628824

    Lithium (Li+) absorption across the low-resistance epithelium of the rabbit gall-bladder was studied in order to elucidate possible routes and mechanisms of Li+ transfer. Li+ at a concentration of 0.4 mM in both mucosal and serosal media did not affect isosmotic mucosa-to-serosa fluid absorption......+ absorptions occurring at 50 mM Na+ were inhibited to the same degree by mucosal 1 mM amiloride. Substitution of 5-50 mM (44%) Na+ by Li+ in the external medium dose-dependently depressed Na+ absorption by up to 76%, while substitution by 50 mM choline had no significant effect.

    There are conflicting data in the literature regarding the reproducibility of the gallbladder ejection fraction (GBEF) measured by fatty meal cholescintigraphy (CS). We aimed to test the reproducibility of GBEF measured by fatty meal CS. Thirty-five subjects (25 healthy volunteers and 10 patients with chronic abdominal pain) underwent fatty meal CS twice in order to measure GBEF1 and GBEF2. The healthy volunteers underwent a repeat scan within 1-13 months from the first scan. The patients underwent a repeat scan within 1-4 years from the first scan and were not found to have chronic acalculous cholecystitis (CAC). Our standard fatty meal was composed of a 60-g Snickers chocolate bar and 200 ml full-fat yogurt. The mean {+-} SD values for GBEF1 and GBEF2 were 52{+-}17% and 52{+-}16%, respectively. There was a direct linear correlation between the values of GBEF1 and GBEF2 for the subjects, with a correlation coefficient of 0.509 (p=0.002). Subgroup data analysis of the volunteer group showed that there was significant linear correlation between volunteer values of GBEF1 and GBEF2, with a correlation coefficient of 0.473 (p=0.017). Subgroup data analysis of the non-CAC patient group showed no significant correlation between patient values of GBEF1 and GBEF2, likely due to limited sample size. This study showed that fatty meal CS is a reliable test in gallbladder motility evaluation and that GBEF measured by fatty meal CS is reproducible

    Full Text Available BACKGROUND: Increased epidermal growth factor receptor (EGF receptor expression has been noted in various cancers and has become a useful target for therapeutic interventions. Small studies from Asia and Australia have demonstrated EGFR over-expression in gallbladder cancer. We sought to evaluate the expression of EGFR in a series of 16 gallbladder cancer patients from North America. METHODS: Using tumor registry data, we identified 16 patients diagnosed with gall bladder carcinoma at our medical center between the years of 1998 and 2005. We performed a retrospective review of these patients' charts, obtained cell blocks from pathology archives and stained for EGFR and Her2/neu. RESULTS: Fifteen of sixteen patients were noted to over-express EGFR. Three were determined 1+, nine were 2+ and three were 3+. Eight patients had poorly differentiated adenocarcinoma, six had moderately differentiated and two had well-differentiated tumors. In this small series, there was a trend toward shorter survival and more poorly differentiated tumors in patients with greater intensity of EGFR expression. One patient was EGFR negative but 3+ for erb-2/Her 2-neu expression. No patient co-expressed EGFR and Her-2-neu. Median survival of patients in this series was 17 months. CONCLUSION: In view of our observations confirming the over-expression of EGFR in our patient population in North America, and the recent success of EGFR targeted therapies in other solid tumors that over-express EGFR, it may now be appropriate to evaluate agents targeting this pathway either as single agents or in combination with standard chemotherapy.

    1994-01-01

    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.

    Rationale and objectives: To evaluate if contrast enhanced sonography (CES) can help to detect gallbladder inflammation and differentiate between acute and chronic cholecystitis. Materials and methods: Thirty-three patients with clinical suspicion of acute cholecystitis were examined with CES before cholecystectomy. Thirty patients with no history of gallbladder disease served as control. CES was performed using 2.5 mL SonoVue. A small mechanical index was chosen (0.1). The enhancement pattern of the gallbladder was ranked in a three-point scale: no enhancement, low enhancement and strong enhancement. 28/33 patients underwent surgery. Sonographic findings were compared to histological results. Results: In 16/20 cases with histological proven acute cholecystitis, the gallbladder wall showed a strong enhancement. Low enhancement was found in four patients with acute and in six patients with chronic cholecystitis. The gallbladder wall of two patients with chronic inflammation and all patients (30/30) of the control group showed no enhancement. Conclusion: CES is a feasible tool for detecting gallbladder inflammation. Differentiating between acute and chronic cholecystitis seems to be possible.

    Ectopic liver and gallbladder are rare anomalies usually not accompanied by any symptoms and are found during surgical exploration or autopsy. We aimed to find a cause of this anomaly using somatic cell nuclear transfer (SCNT) technology, which can produce genetically identical organisms. A cloned beagle having ectopic organs was produced and died on the day of birth. Major and ectopic organs were fixed and underwent histologic analysis. SCNT was performed using cells derived from the dead puppy to produce reclones. Normality of internal organs in the original donor dog and recloned dogs was evaluated by computed tomography. While a liver without the gallbladder was located in the abdominal cavity of the cloned dog, a well-defined, reddish brown mass with a small sac was also positioned outside of the thoracic cavity. Histologically, they presented as normal liver and gallbladder. Five reclones were produced, and computed tomography results revealed that the original donor dog and reclones had normal liver and gallbladder structure and location. This is the first report of both ectopic liver and gallbladder in an organism and investigation on the etiology of these abnormalities. Normal organ structure and position in the original donor dog and reclones suggests that the ectopic liver and gallbladder is a possible nonheritable anomaly. PMID:26159091

  5. Cordycepin Induces S Phase Arrest and Apoptosis in Human Gallbladder Cancer Cells

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

    To evaluate the relationship between gallbladder function and calcification of gallstones, we studied gallbladder contractility by oral cholecystography, the computed tomography (CT) number of stones for 30 gallstone patients, calcium content of 13 stones operatively extirpated, and the degree of inflammatory change in 13 surgical gallbladder specimens. There was significant correlation between the calcium content and CT numbers of stones, and 1% of the calcium content of gallstone was approximately equal to 40 Hounsfield Units (HU) of the CT number. The calcium content of stones in patients with normal gallbladder contractility was extrapolated to be below 1.5%, while that with poor contractility ranged from 0% to 21%. Additionally there is a possibility that calcium content increases, related to the inflammatory change of gallbladder. Hence our results suggested that measurement of the CT number of stones is useful to evaluate the calcium content of gallstones, and that the gallbladder contractility could be one of the factors to influence calcification of stones.

Out of 67 patients considered in this study, 53 were men (79.1% and 14 were women (20.9%. The average age was 52 years for men and 53 years for women (range 19-86 years. 59 (88% were patients with known medical history of peptic ulcer disease. Endoscopy has been performed for 64 patients (95.6%. Specific medical treatment was started immediately for all patients. For 47 patients (70.1% the hemorrhage stopped with conservative treatment, 8 patients (12% benefit by endoscopic treatment and 12 patients (17.9% underwent surgery. The postoperative morbidity rate was 16.7%. Comorbidities were present in 43 patients (64.2%. Failure of medical conservative treatment has been observed in 7 cases (13%, and failure of endoscopic procedures in 2 cases (20%. The risk factors involved in therapy outcomes of bleeding duodenal ulcer are: age, the severity of hemorrhage confirmed by endoscopy, the hemorrhagic episodes in medical history and the time of surgery. Conclusion: The prognosis of bleeding duodenal ulcer after bleeding is highly correlated with the time that the treatment starts, the severity of hemorrhage, comorbid conditions and age.

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

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    To assess the diagnostic accuracy of Roc kall scoring system for predicting in-hospital re-ble- eding in cirrhotic patients presenting with variceal bleed. Material and Methods: This descriptive case series study was conducted at Department of Medicine Combined Military Hospital Lahore from December 2013 to May 2014. We included patients with liver cirrhosis who presented with upper GI bleeding and showed varices as the cause of bleeding on endoscopy. Clinical and endoscopic features were noted to calculate Rockall score. Patients with score < 2 and > 8 were included. After treating with appropriate pharmacological and endoscopic therapy, patients were followed for re-bleeding for 10 days. Diagnostic accuracy was assessed by calculating sensitivity, specificity, positive and negative predictive values using 2 x 2 tables. Results: In the study, 175 patients were included. Mean age was 51.5 ± 1.22 years. Male to female ratio was 1.5 to 1.0 out of 175 patients, 157 patients (89.7%) were of low risk group (score = 2) while 18 patients (10.3%) were in high risk group (score > 8). In low risk group, re-bleeding occurred only in 2 patients (1.2%) while in high risk group, re-bleeding occurred in 14 patients (78%). Rockall score was found to have good diagnostic accuracy with sensitivity of 87.5%, specificity of 97.48%, positive predictive value of 77.8% and negative predictive value of 98.7%. Conclusion: In cases of variceal bleed, frequency of re-bleed is less in patients who are in low risk category with lower Rockall score and high in high risk patients with higher rockall score. The Rockall score has a good diagnostic accuracy in prediction of re-bleed in variceal bleeding. (author)

    Pai, Menaka; Chan, Anthony; Barr, Ronald

    2013-09-01

    Heavy menstrual bleeding (HMB) is a common clinical problem; population-based studies estimate that approximately 10-35% of women report this symptom during their lifetime, while about 5% of women consult a physician for evaluation of HMB. Patients with HMB account for 15% of all referrals to gynaecologists and are frequently seen by haematologists in bleeding disorder clinics as well. Heavy menstrual bleeding can be caused by a wide variety of local and systemic factors, so a careful clinical and laboratory evaluation is often necessary to determine the aetiology and guide appropriate management. This review discusses the definition, causes and clinical outcomes of HMB. It outlines a diagnostic approach and focuses on medical (as opposed to surgical) treatments. Throughout, areas of controversy and opportunities for further research are highlighted. PMID:23829452

    Fibrinogen concentrate as part of treatment protocols increasingly draws attention. Fibrinogen substitution in cases of hypofibrinogenaemia has the potential to reduce bleeding, transfusion requirement and subsequently reduce morbidity and mortality. A systematic search for randomised controlled...... trials (RCTs) and non-randomised studies investigating fibrinogen concentrate in bleeding patients was conducted up to November 2013. We included 30 studies of 3480 identified (7 RCTs and 23 non-randomised). Seven RCTs included a total of 268 patients (165 adults and 103 paediatric), and all were...... mortality were lacking. Weak evidence from RCTs supports the use of fibrinogen concentrate in bleeding patients, primarily in elective cardiac surgery, but a general use of fibrinogen across all settings is only supported by non-randomised studies with serious methodological shortcomings. It seems pre...

  14. Radionuclide detection of lower gastrointestinal bleeding sites

    International Nuclear Information System (INIS)

    A retrospective review of two years' experience with radionuclide screening to detect lower gastrointestinal bleeding sites was conducted at New York's Montefiore Medical Center. Of 82 studies performed in 63 patients, 13 identified active bleeding sites. Only three of eight angiograms obtained in these 13 patients were positive. Thirteen contrast angiograms were performed in the group of 50 patients with negative radionuclide studies of which ten were negative and one was equivocal. The results of this study suggest that the Tc-99m sulfur colloid study for active lower gastrointestinal (GI) bleeding is an effective screening procedure. Positive studies help determine which vessel to catheterize selectively if an angiogram is to be performed. If vascular ectasis is still suspected following a negative radionuclide study, contrast angiography can be more efficaciously performed on a nonemergent basis

  15. Radiotherapy in benign uterine bleeding disorders

    International Nuclear Information System (INIS)

    Radiotherapy was earlier a method of choice for treatment of benign bleeding disorders (metropathia), especially in woman of high surgical risk. During the period 1912 to 1977 933 women with benign bleeding disorders were treated at Radiumhemmet with intracavitary brachytherapy or external irradiation or a combination of both. The result with regard to cure of the uterine bleedings was good (48%). Hormonal withdrawal symptoms after treatment were noted in 45% of the patients. In the long term follow up an increased risk of cardiovascular death was found in women treated before menopause. Malignant tumours occurred in 107 cases versus 90.2 expected. The estimated ovarian dose of ionizing radiation varied from 3.5 Gy to 6.0 Gy for the three standard techniques. Two women gave birth to a healthy child 4 and 5 years after intracavitary radium treatment. The estimated absorbed dose to the ovaries in these two women were 1 Gy and 4 Gy, respectively

    Introduction Cholecystectomy for benign gallbladder diseases can lead to previously undiagnosed gallbladder cancer during histopathological evaluation. Despite some controversy over its usefulness, histopathological evaluation of all gallbladder specimens is common in most hospitals. We evaluated the results of routine pathology of the gallbladder after cholecystectomy for benign gallbladder diseases with regard to unexpected primary gallbladder cancer (UPGC). Methods Patients undergoing cholecystectomy because of benign gallbladder diseases between 2009 and 2013 were enrolled in this study. All gallbladder specimens were sent to the pathology department, and histopathological reports were examined in detail. The impact of demographic features on pathological diagnoses and prevalence of UPGC assessed. Data on additional interventions and postoperative survival for patients with UPGC were collected. Results We enrolled 1,747 patients (mean age, 48.7±13.6 years). Chronic cholecystitis was the most common diagnosis (96.3%) and was associated significantly with being female (p=0.001). Four patients had UPGC (0.23%); one was stage T3 at the time of surgery, and the remaining three cases were stage T2. Conclusions Routine histopathological examination of the gallbladder is valuable for identification of cancer that requires further postoperative management. PMID:26924485

    AIM: To investigate the role of cydin D1, p16 and retinoblastoma in cancerous process of gallbladder carcinomas and to assess the relation between cyclin D1, p16, Rb and the biological characteristics of gallbladder carcinoma.METHODS: Forty-one gallbladder carcinoma, 7 gallbladder adenoma and 14 chronic cholecystitis specimens were immunohistochemically and histopathologically investigated for the relation of cyclin D1, p16 and Rb with Nevin staging and pathologic grading.RESULTS: The expression rates of abnormal cyclin D1 in gallbladder carcinoma (68.3%)and gallbladder adenoma(57.1%) were significantly higher than those in chronic cholecystitis (7.1%) (P<0.05). No significant difference was found both among the pathological grades G1, G2 and G3and among Nevin stagings S1-S2, S3 and S4-S5 of gallbladder carcinoma. The positive rates of p16 (48.8%) and Rb(58.5%) in gallbladder carcinoma were significantly lower compared to those in adenoma (100.0%) and cholecystitis(100.0%) (P<0.05). The positive rates of p16 and Rb in Nevin stagings S1-S2 (80.0% and 90.0%) and S3 (46.2%and 61.5%) gallbladder carcinomas were significantly higher than those in S4-S5 (33.3% and 38.8%) (P<0.05),and those in pathologic grades G1 (54.5% and 81.8%) and G2 (50.0% and 62.5%) gallbladder carcinoma were significantly higher than those in G3 (28.6% and 35.7%)(P<0.05). The protein expression of p16 and Rb had a negative-correlation in gallbladder carcinoma (r = -0.2993,P<0.05), and this negative-correlation was correlated with Nevin staging (P<0.05). Moreover, the protein expression of p16 and cyclin D1 had a negative-correlation in gallbladder carcinoma (r = -0.9417, P<0.05).CONCLUSION: Cyclin D1 may play a role in the early stage of gallbladder carcinoma. Mutation of p16 and Rb genes might be correlated with progression of gallbladder carcinoma.Analysis of p16 and Rb can estimate the prognosis of gallbladder carcinoma. Expression of p16 and Rb may be correlated with Nevin

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

    Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is notapparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians.

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

    Full Text Available BackgroundGallbladder cancer is sometimes incidentally uncovered following cholecystectomy for gallstones diseases. The supposed highly variable prevalence of incidental gallbladder cancer through our country is unknown.ObjectiveTo explore the prevalence of incidental gallbladder cancer in our tertiary-care hospital.MethodsA cross-sectional study was carried out on patients who consecutively underwent cholecystectomy due to gallstones disease at Faculdade Pernambucana de Saúde, Instituto de Medicina Integral Professor Fernando Figueira - FPS/IMIP, from January, 2007 to December, 2010. Data on incidental gallbladder cancer patients were explored for prevalence estimation and description of our experience with the management of this malignancy.ResultsOur analysis involved 2018 patients with a marked predominance of women (n=1.697; 84.1% over men (n=321; 15.9%. The 3-year prevalence estimate of 0.34% was recorded for incidental gallbladder cancer in our sample. Regarding tumor staging, there were 1 T1a, 1 T1b, and 5 T2 adenocarcinoma tumors. Laparoscopic cholecystectomy alone was performed for the T1a tumor, and additional radical surgery was performed in five others. One patient presented metastatic disease at the time of repeat surgery. The final pathology revealed residual/additional disease in all T2 tumors after radical surgery whereas the T1b patient underwent a salvage Whipple’s procedure due to a secondary distal cholangiocarcinoma. The patient with T1a tumor is alive after 3-year follow-up but all of the others died because of disease recurrence/progression up to 12 months.ConclusionThis study confirms the poor prognosis of Gallbladder cancer even when incidentally diagnosed following cholecystectomy and supposes a 3-year prevalence estimate of 0.34% for incidental gallbladder cancer in our Center from Pernambuco State, Brazil.

    To determine whether radiofrequency thermal ablation can be used to treat benign cystic lesions in a porcine gallbladder model. This experimental study of radiofrequency thermal ablation involved the use of 15 exvivo porcine gallbladders and 15-G expandable needle electrodes. To investigate optimal temperature parameters, three groups of five were designated according to target temperature:Group A: 70 deg C; Group B: 80 deg C; Group C: 90 deg C. After the target temperature was reached, ablation lasted for one minute. Gallbladder width, height and length were measured before and after ablation , and the estimated volume reduction ratios of the three groups were compared. Whether adjacent liver parenchyma around the gallbladder fossa was ablated by heat conducted from hot bile was also determined, and the thickness of the ablated area of the liver was measured. The volume reduction ratio in Group A, B and C was 42.7%, 41.7% and 42.9%, respectively ({rho}>.05). In all 15 cases, gallbladder walls lost their transparency and elasticity at about 70 deg C. In nine of ten cases in Groups B and C, the hepatic capsule around the gallbladder fossa was retracted at about 80 deg C. The mean thickness of liver parenchymal damage adjacent to the gallbladder was 5.4 mm in Group B and 9.8 mm in Group C. In Group A livers, only one case showed minimal gradual parenchymal change. Microscopically, all three groups showed complete coagulation necrosis of the wall. On the basis of this feasibility study, radiofrequency thermal ablation is potentially suitable for the ultrasound-guided treatment of symptomatic cystic lesions including benign hepatic or renal cyst.

  7. Diffusion-weighted MRI for differentiation of benign from malignant lesions in the gallbladder

    International Nuclear Information System (INIS)

    Aim: To investigate the value of diffusion-weighted imaging (DWI) for differentiating benign from malignant gallbladder lesions. Materials and methods: One hundred and twenty-six patients who had undergone magnetic resonance imaging (MRI) with DWI, in whom the histopathological diagnosis of their gallbladder lesions was confirmed by biopsy or surgery were retrospectively analysed. Thirty-six malignant and 90 benign lesions were included. Two radiologists categorized gallbladder lesions into seven types on two imaging sets [T2-weighted imaging (WI) alone and combined T2WI and DWI (b = 800 s/mm2)] according to the presence of wall thickening, layered patterns, morphology of the mass, and diffusion restriction. Disagreements were resolved in consensus. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of each imaging set for diagnosing gallbladder carcinoma were calculated. The diagnostic performance of each imaging set was calculated using receiver operating characteristic (ROC) curve analysis. Additionally, ADC values of malignant and benign gallbladder lesions were compared separately for 1.5 and 3 T MRI. Results: The sensitivity, specificity, PPV, and NPV of diagnosis at T2WI were 97.2%, 86.7%, 74.5%, and 98.7%, respectively. The sensitivity, specificity, PPV, and NPV using combined T2WI and DWI were 97.2%, 92.2%, 83.3%, and 98.8%, respectively. Diagnostic accuracy for gallbladder carcinoma slightly improved after adding DWI, from 0.92 to 0.95 (p −3 and 1.72 ± 0.56 × 10−3 mm2/s, respectively, at 1.5 T (p −3 and 2.2 ± 0.72 × 10−3 mm2/s, respectively, at 3 T (p < 0.001). Conclusion: DWI can improve diagnostic accuracy for differentiating benign from malignant gallbladder lesions

    Pectic ulcer is the most frequent cause of gastrointestinal bleeding. The homeostatic mechanism of bleeding, and coagulation, does not happen with values of pH less than 5,0. Therefore neutralization of gastric acidity (pH more than 5,0) is a recourse of control, improve the evolution and healing of peptic ulcer and to avoid a new bleeding. The aim of this study was to compare the results of treatment with omeprazole and ranitidine, in 57 patients admitted at emergency room of the Hospital Central de la Polic a Nacional del Per with endoscopic diagnosis of peptic ulcer, using Forrest classification. Patients received omeprazole 40 mg in bolus IV, followed by continuos infusion of 8 mg/hour for 72 hours (group A) or ranitidine 50 mg IV each 8 hours for 72 hours (group B). A new endoscopy was made 72 hours after admission demostrated a succesful therapy in both group. Bleeding stopped in 26/27 patients in group A (96,2%) and in 23/30 patients in group B (76,6%) (pomeprazole IV is more effective than ranitidine IV in the control of UGB because of peptic ulcer and provides a faster healing.

  9. Endometrial biopsy findings in postmenopausal bleeding

    International Nuclear Information System (INIS)

    To study endometrial histopathology in women presenting with postmenopausal bleeding. A two-year study from January 2003 to December 2004 of 100 cases of postmenopausal bleeding was conducted at Combined Military Hospital, Sialkot. The histopathology of endometrial biopsy specimens was done to find out the causes of postmenopausal bleeding in these ladies. All these 100 patients had confirmed menopause and the average age was 55 years and above. The most common histopathological diagnosis was senile endometrial atrophy (27%), followed by simple cystic hyperplasia in (17%). Three cases of simple cystic hyperplasia had coexistent ovarian tumors. Glandular hyperplasia without atypia was seen in 6% and with atypia in 4%. Other causes were endometritis (13%), endometrial polyps (8%), proliferative phase endometrium (6%) and secretary phase endometrium (5%). Endometrial carcinoma was seen in (6%) cases, (8%) biopsy specimens were non-representative. Although senile endometrial atrophy was most commonly found in these ladies but a significant percentage of endometrial hyperplasia and endometrial cancer implies the need for investigating all cases of postmenopausal bleeding. Bimanual examination and pelvic ultrasonography should be combined with endometrial sampling so that rare pelvic pathologies may not be missed. (author)

  12. Endovascular Management of Acute Bleeding Arterioenteric Fistulas

    International Nuclear Information System (INIS)

    The objective of this study was to review the outcome of endovascular transcatheter repair of emergent arterioenteric fistulas. Cases of abdominal arterioenteric fistulas (defined as a fistula between a major artery and the small intestine or colon, thus not the esophagus or stomach), diagnosed over the 3-year period between December 2002 and December 2005 at our institution, were retrospectively reviewed. Five patients with severe enteric bleeding underwent angiography and endovascular repair. Four presented primary arterioenteric fistulas, and one presented a secondary aortoenteric fistula. All had massive persistent bleeding with hypotension despite volume substitution and transfusion by the time of endovascular management. Outcome after treatment of these patients was investigated for major procedure-related complications, recurrence, reintervention, morbidity, and mortality. Mean follow-up time was 3 months (range, 1-6 months). All massive bleeding was controlled by occlusive balloon catheters. Four fistulas were successfully sealed with stent-grafts, resulting in a technical success rate of 80%. One patient was circulatory stabilized by endovascular management but needed immediate further open surgery. There were no procedure-related major complications. Mean hospital stay after the initial endovascular intervention was 19 days. Rebleeding occurred in four patients (80%) after a free interval of 2 weeks or longer. During the follow-up period three patients needed reintervention. The in-hospital mortality was 20% and the 30-day mortality was 40%. The midterm outcome was poor, due to comorbidities or rebleeding, with a mortality of 80% within 6 months. In conclusion, endovascular repair is an efficient and safe method to stabilize patients with life-threatening bleeding arterioenteric fistulas in the emergent episode. However, in this group of patients with severe comorbidities, the risk of rebleeding is high and further intervention must be considered

    Full Text Available Background: Abnormal Uterine Bleeding (AUB is referred as bleeding outside of normal menstruation pattern and it is the most common gynecological problem for women of all ages. This study was evaluated the correlation of menstrual bleeding patterns and endometrial histopathological findings in perimenopausal women. Methods: This study was done on perimenopausal aged women presented with AUB for the last 6 months at a gynecology clinic of a tertiary medical center. Only the patients with isolated endometrial causes of AUB were selected for study. A total of 313 cases were included in the study. Abnormal bleeding patterns of the patients were recorded and endometrial sampling was performed to all women. AUB was classified as menorrhagia, metrorrhagia, menometrorrhagia, polymenorrhea, intermenstrual bleeding, and histopathological findings were classified as Proliferative Endometrium (PE, Secretory Endometrium (SE, Disordered Proliferative Pattern (DPP, Endometrial Polyp (EP, Chronic Endometritis (CE, Endometrial Hyperplasia (EH, and Endometrial Adenocarcinoma (CA. Results: The most common bleeding pattern was menorrhagia (45.0% and the most common histopathological finding was PE+SE (52.0% in our study. PE+SE and endometrial hyperplasia without atypia were found more common in menorrhagia group. The most histopathological findings were found PE+SE in menometrorrhagia and polymenorrhea group (P 0.05. Conclusions: We concluded that although menometrorrhagia and polymenorrhea were significantly more associated with PE+SE, intermenstrual bleeding was significantly more associated with EP and CE. It is noteworthy that endometrial hyperplasia without atypia is significantly higher in patients with menorrhagia which is the most common abnormal bleeding pattern in perimenopausal aged women.

  14. The microbiological and clinical characteristics of invasive salmonella in gallbladders from cholecystectomy patients in kathmandu, Nepal.

    Directory of Open Access Journals (Sweden)

    Sabina Dongol

    Full Text Available Gallbladder carriage of invasive Salmonella is considered fundamental in sustaining typhoid fever transmission. Bile and tissue was obtained from 1,377 individuals undergoing cholecystectomy in Kathmandu to investigate the prevalence, characteristics and relevance of invasive Salmonella in the gallbladder in an endemic area. Twenty percent of bile samples contained a Gram-negative organism, with Salmonella Typhi and Salmonella Paratyphi A isolated from 24 and 22 individuals, respectively. Gallbladders that contained Salmonella were more likely to show evidence of acute inflammation with extensive neutrophil infiltrate than those without Salmonella, corresponding with higher neutrophil and lower lymphocyte counts in the blood of Salmonella positive individuals. Antimicrobial resistance in the invasive Salmonella isolates was limited, indicating that gallbladder colonization is unlikely to be driven by antimicrobial resistance. The overall role of invasive Salmonella carriage in the gallbladder is not understood; here we show that 3.5% of individuals undergoing cholecystectomy in this setting have a high concentration of antimicrobial sensitive, invasive Salmonella in their bile. We predict that such individuals will become increasingly important if current transmission mechanisms are disturbed; prospectively identifying these individuals is, therefore, paramount for rapid local and regional elimination.

    This study was undertaken to investigate the effect of ingestion of 80 g Vivonex on gallbladder volume, plasma cholecystokinin (CCK), and pancreatic polypeptide (PP) in eight healthy volunteers and to compare the results with those obtained after ingestion of 60 ml corn oil. Gallbladder volumes were measured by ultrasonography. Plasma CCK was determined by radioimmunoassay using region-specific antibodies; antibody 1703 binds to COOH-terminal CCK-peptides containing at least 14 amino acid residues, while antibody T204 binds to COOH-terminal CCK-peptides containing the sulfated tyrosine region. Plasma PP was also measured by radioimmunoassay. Ingestion of Vivonex induced significant increases in plasma CCK (0.6 +/- 0.1 to 4.6 +/- 0.6 pM, antibody 1703; 1.8 +/- 0.3 to 5.9 +/- 0.5 pM, antibody (T204; P less than or equal to 0.0005) and decreases in gallbladder volume (21.4 +/- 2.8 to 11.2 +/- 2.3 cm3; P = 0.0001). Integrated plasma CCK secretion and gallbladder contraction after Vivonex were not significantly different from the results found after corn oil. Both Vivonex and corn oil-induced small increases in plasma PP. We conclude that Vivonex is a potent stimulus for the secretion of CCK and contraction of the gallbladder. PMID:3539560

    An 83-year-old woman, diagnosed as having cholelithiasis, was admitted to the Department of Surgery, Nippon Medical School, with right hypochondrial pain. Ultrasonography and computed tomography revealed a mass in the gallbladder fundus and a hypovascular tumor in the anterior segment of the liver. Magnetic resonance imaging showed stenosis of the intrahepatic bile duct and dilatation of its proximal portion. She was diagnosed as having intrahepatic bile duct carcinoma combined with gallbladder carcinoma. At laparotomy, there was evidence of multiple peritoneal metastases and intraoperative histological examination of the gallbladder tumor revealed adenocarcinoma. Accordingly, only cholecystectomy and needle biopsy of the liver tumor was performed. Histological examination of the gallbladder revealed papillary adenocarcinoma invading the muscularis propria with medullary growth or intermediate stroma. There was no microvessel invasion, no perineural invasion and no lymph node involvement. On the other hand, the liver tumor was a cholangiocarcinoma with a well-differentiated tubular pattern. Therefore, this was a rare case of synchronous carcinoma of the gallbladder associated with intrahepatic bile duct carcinoma. PMID:10690592

    Laparoscopic surgery has many advantages,but it is difficult for a surgeon to achieve the necessary surgical skills.Recently,virtual training simulations have been gaining interest because they can provide a safe and efficient learning environment for medical students and novice surgeons.In this paper,we present a hybrid modeling method for simulating gallbladder removal that uses both the boundary element method (BEM) and the finite element method (FEM).Each modeling method is applied according to the deformable properties of human organs:BEM for the liver and FEM for the gallbladder.Connective tissues between the liver and the gallbladder are also included in the surgical simulation.Deformations in the liver and the gallbladder models are transferred via connective tissue springs using a mass-spring method.Special effects and techniques are developed to achieve realistic simulations,and the software is integrated into a custom-designed haptic interface device.Various computer graphical techniques are also applied in the virtual gallbladder removal laparoscopic surgery training.The detailed techniques and the results of the simulations are described in this paper.

  18. Bicarbonate Secretion in the Murine Gallbladder - Lessons for the Treatment of Cystic Fibrosis

    Directory of Open Access Journals (Sweden)

    Cuthbert AW

    2001-07-01

    Full Text Available The epithelium lining the gallbladder of mammalian species has absorptive and secretory functions. An important function is the secretion of a bicarbonate rich fluid that helps neutralise stomach acid and provides an appropriate environment for intestinal enzymes. In cystic fibrosis (CF this secretory function is lost. This study concerns the bicarbonate secreting activity of murine gallbladders in vitro using wild type and CF mice and four main questions are considered as follows: a Does the murine gallbladder secrete bicarbonate electrogenically and is this prevented in CF? b Can the secretory activity in CF gallbladders be restored by gene therapy or pharmacologically? c How is the cystic fibrosis transmembrane conductance regulator (CFTR involved in bicarbonate secretion? d Does the data offer prospects for the treatment of CF?. Work from both the author's laboratory and the literature will be reviewed. Consideration of the currently available data indicates that the wild type murine gallbladder does secrete bicarbonate electrogenically and that this is absent in CF mice. Further it has been demonstrated that bicarbonate secretory activity can be restored by both gene therapy and by the use of drugs. The role of CFTR in bicarbonate secretion remains equivocal. Much evidence suggests that CFTR can act as a channel for HCO(3(- ions as well as Cl(- ions, while others propose a parallel arrangement of CFTR with a Cl(-/HCO(3(- exchanger is necessary. The matter is further complicated by the regulatory role of CFTR on other transporting activities. Opportunities for possible application to man are discussed.

    Four patients with spontaneous bleeding from the pancreas are described. Transpapillary bleeding is diagnosed endoscopically. Angiography can demonstrate the eroded vessel directly. Ultrasound, CT and ERCP demonstrate the underlying abnormality in the pancreas. Bleeding into a cyst produces characteristic echoes, or an increase in density. NMR is able to demonstrate pancreatitis and pancreatic pseudo-cysts. Early diagnosis is extremely important, since without appropriate surgery, pancreatic bleeding is frequently fatal. 7 figs.

    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

  4. Scintigraphic detection and localization of gastrointestinal bleeding sites

    International Nuclear Information System (INIS)

    Successful management of acute gastrointestinal (GI) bleeding usually depends on accurate localization of the bleeding site. History and clinical findings are often misleading in determination of the site of hemorrhage. The widespread application of flexible endoscopy and selective arteriography now provide accurate diagnoses for the majority of patients bleeding from the upper GI tract, but lower GI bleeding still poses a serious diagnostic challenge. Endoscopy and barium studies are of limited value in examining the small bowel and colon in the face of active hemorrhage. Arteriography, although successful in many cases (3-5), has limitations. The angiographic demonstration of bleeding is possible only when the injection of contrast material coincides with active bleeding at a rate greater than 0.5 ml/min, and since lower GI bleeding is commonly intermittent rather than continuous, a high rate of negative angiographic examinations has been reported. The diagnosis of lower GI bleeding is usually easy to make. In contrast, localizing the site of bleeding may be extremely difficult. Using the techniques described the nuclear physician may be able to detect the bleeding site precisely. However, if the cautions detailed are not observed, the tracer studies will show GI bleeding, but not at the true bleeding site. This must be carefully understood and avoided. Done correctly, these tests can have a major impact on patient care

    Ultrasonography has been popular for the diagnosis of gallbladder diseases since the mid-1970s. Although this technique has replaced oral cholecystography (OCG) for the diagnosis of cholecystolithiasis, it has not gained popularity in the diagnosis of adenomyomatosis of the gallbladder (AMMG). We examined 141 patients with clinically suspected gallbladder disease. Ultrasonography (previously done by a radiologist) had produced no positive findings. On ultrasonographic re-evaluation by the same radiologist, but in the presence of a surgeon from our study group, 64 cases of AMMG were detected. OCG revealed the diagnosis of AMMG in 13 other cases. In the study group there were no false-positive results. However, the false-negative rate of sonography in diagnosing AMMG was 16.9%. Thus, in our opinion ultrasonography is a worthwhile technique in diagnosing AMMG done by a surgeon. PMID:2180093

    According to published reports, a common feature of xanthogranulomatous cholecystitis is the presence of intramural hypoattenuated nodules in thickened gallbladder wall. These nodules can, however, also be seen in pathological conditions such as acute cholecystitis, hyperplastic cholecystoses (cholesterolosis and adenomyomatosis), gallbladder cancer, and other inflammatory diseases such as tuberculosis. Retrospective review of the abdominal CT findings in 622 patients who for various reasons underwent cholecystectomy during a one-year period showed that intramural nodules were present in 60. In this pictorial essay we illustrate the imaging features of the many different pathological conditions which give rise to intramural hypoattenuated nodules in thickened wall of the gallbladder, correlating these features with the histopathological findings.

    An 86 year-old woman with a past medical history significant for abdominal hernia and Alzheimer dementia presented to the Emergency Department with a 24 hour history of acute right upper quadrant pain associated with nausea and non-bilious emesis. Physical exam revealed right sided abdominal tenderness with associated mass. All laboratory values were within normal ranges. Both abdominal ultrasound and computed tomography of the abdomen/pelvis revealed a large distended gallbladder with wall thickening and gallstones. Based on presentation and radiologic findings, the emergency general surgery service was consulted for suspected acute cholecystitis. The patient was then admitted for intravenous antibiotics and scheduled for laparoscopic cholecystectomy the following day. Intra-operative findings revealed volvulus with acute necrosis of the entire gallbladder. The gallbladder had a long pedunculated cystic duct and artery that was detorsed before proceeding with resection. Postoperatively, the patient did well and was discharged a few days later tolerating a regular diet.

    Full Text Available Context Heterotopia of the pancreas can be defined as the presence of pancreatic tissue in an abnormal location without any continuity with the main body of the pancreas. Heterotopic pancreatic tissue located in the gallbladder is a rare entity. Despite being a congenital condition, it takes years for heterotopic pancreas to become symptomatic. Case report An 80-year-old male patient presented to our hospital with a two-week history of abdominal pain, nausea and vomiting aggravated after meals. Abdominal ultrasonography revealed minimal wall edema and small grain-sized gallstones in the gallbladder. The patient was hospitalized and laparoscopic cholecystectomy was performed for acute cholecystitis. Pathologic examination showed a 6 mm nodular mass of pancreatic tissue in the gallbladder wall, comprised mainly of ductal and acinic structures and a few endocrine cells. Conclusion We found this case of pancreatic heterotopia worth reporting because of its rare incidence.

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

    International Nuclear Information System (INIS)

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

    The gallbladder is an unusual location of pancreatic heterotopia, defined as the presence of pancreatic tissue lacking anatomical and vascular continuity with the main body of the gland. A 28-year-old man presented with anorexia, nausea and pain in the right upper abdomen. On physical examination, the abdomen was tender to palpation and Murphy sign was positive. The patient underwent a cholecystecomy. This case, in our opinion,is very interesting since it permits to consider a controversial issue in the pathology of the gallbladder. The histological appearance of ductal structure in pancreatic heterotopia resembles the histological picture of both Aschoff-Rokitansky (AR) sinuses and adenomyomas. This finding suggests that these lesions are linked by a common histogenetic origin. We suggest that the finding of an adenomyoma in the gallbladder should prompt an extensive sampling of the organ in order to verify the coexistence of pancreatic rests.

    At Odense University Hospital (OUH), 5-9% of all unselected cardiac surgical patients undergo reoperation due to excessive bleeding. The reoperated patients have an approximately three times greater mortality than non-reoperated. To reduce the rate of reoperations and mortality due to postoperative...... bleeding, we aim to identify risk factors that predict reoperation. A total of 1452 consecutive patients undergoing cardiac surgery using extracorporeal circulation (ECC) between November 2005 and December 2008 at OUH were analysed. Statistical tests were used to identify risk factors for reoperation. We...... after cardiac surgery was low ejection fraction, high EuroSCORE, procedures other than isolated CABG, elongated time on ECC, low body mass index, diabetes mellitus and preoperatively elevated s-creatinine. Reoperated patients significantly had a greater increase in postoperative s-creatinine and higher...

    Leeches are blood-sucking hermaphroditic parasites that attach to vertebrate hosts, bite through the skin, and suck out blood. When leeches feed, they secrete an anticoagulant (hirudin), which helps them get a full meal of blood. This is the first report of leech removal from external auditory canal. Previous leech involvement cases were explained in nasopharynx, larynx, pharynx, eye, and gastrointestinal tract. Prominent sign of all cases was active bleeding from the leech attachment site; t...

    BACKGROUND: Defective contractile motility of the gallbladder is an important factor for gallstone formation. Estrogen might increase the risk of gallstones and cholecystitis, and estradiol inhibits the contractile activity of isolated strips of guinea pig gallbladder. The potential risks associated with hormone replacement therapy (HRT) include symptomatic gallstones. Phytoestrogen have been used to treat menopause syndromes by replacing traditional estrogen. This experiment aimed to determine the effects of the phytoestrogen genistein on the contractile response of smooth muscle strips isolated from guinea pig gallbladder and its possible mechanism of action. METHODS: Guinea pigs were sacriifced to remove the whole gallbladder. Two or three smooth muscle strips were cut longitudinally. Each strip was suspended in a tissue chamber containing Krebs solution. After 2 hours of equilibration, contractile response indexes were recorded. Different concentrations of genistein were added to the chamber and the contractile responses were measured. Each antagonist was added 2 minutes before genistein to study possible mechanisms. The effect of genistein on calcium-dependent contraction curves and biphasic contraction in calcium-free Krebs solution were measured. RESULTS: Genistein decreased the resting tension dose-dependently, and reduced the mean contractile amplitude and frequency in gallbladder strips. Ranitidine partly inhibited the effect of genistein, but methylene blue, Nω-nitro-L-arginine, and propranolol hydrochloride did not inlfuence this action. Genistein had no signiifcant effects on calcium-dependent contraction. Genistein reduced the ifrst contraction induced by acetylcholine chloride, but did not affect the second contraction caused by CaCl2. CONCLUSIONS: Genistein relaxed smooth muscle isolated from the gallbladder of guinea pigs and this might contribute to the formation of gallstones. The inhibitory action might be related to H2 receptors and

  6. Metabonomic study of human serum in gallbladder cancer by 1H NMR spectroscopy

    International Nuclear Information System (INIS)

    Gallbladder carcinoma (GBC) is one of the most lethal malignancies of upper gastrointestinal tract and it has the highest mortality rate in Chile and India. It has a very high incidence rates in northern India therefore it is also called as an Indian disease. There are several factors which play important role in development of gallbladder cancer including long-standing stones in gallbladder and alterations in composition of bile. Studies on gallstones and gallbladder tissues revealed that benign group can easily be discriminated from malignant group. Many proteomic studies have been performed for different cancers and several responsible serum protein markers have been identified but there is no such metabonomics study that shows the presence of any biomarker associated with gallbladder carcinoma. Identification of such biomarker would help immensely in the diagnostic of GBC. For this study we have collected blood samples (70; including patients from Chronic Cholecystitis (CC), XanthoGranulomatous Cholecystitis (XGC) and Gallbladder Cancer (GBC)) post-operatively (immediately after surgery) from patient undergoing cholecystectomy in Department of Surgical Gastroenterology, SGPGIMS. Control samples were also collected from 20 volunteers after 12 hrs of fasting. 4 ml of blood sample was collected and was allowed to clot in plastic tube for 30 min at room temperature in incubator. The serum was collected by centrifugation and samples were stored at -80 deg C till NMR experiments. 400 μL of serum was used for recording NMR spectra. NMR spectra were recorded at Bruker Avance 800 MHz spectrometer using CPMG pulse sequence with water presaturation. Control serum shows presence of various amino acids and low molecular weight metabolites. Detailed multivariate analysis along with markers found in serum associated with GBC will be presented.

    Fifty consecutive outpatients with bleeding internal hemorrhoids were prospectively treated with a single application of rubber band ligation or infrared coagulation. Complete follow-up observation was obtained in 48 patients (23 underwent rubber band ligation and 25 underwent infrared coagulation). At one month after treatment, 22 patients who underwent rubber band ligation and 16 who underwent infrared coagulation, were symptomatically improved (p less than 0.05). At six months, 15 patients who had undergone rubber band ligation and ten who had infrared coagulation treatment, remained improved (p less than 0.05). There was no statistical difference in the discomfort experienced by either group during or after the procedure as determined by a self-assessment scale. Two patients who underwent rubber band ligation experienced complications--a thrombosed external hemorrhoid developed in one patient and another had delayed rectal bleeding. Although associated with occasional complications after treatment, rubber band ligation is more effective than in infrared coagulation for single session treatment of bleeding internal hemorrhoids.

    AIM To evaluate the efficacy of endoscopic hemoclip in the treatment of bleeding peptic ulcer.METHODS Totally, 40 patients with F1a and F1b hemorrhagic activity of peptic ulcers were enrolled in this uncontrolled prospective study for endoscopic hemoclip treatment. We used a newly developed rotatable clip-device for the application of hemoclip (MD850) to stop bleeding. Endoscopy was repeated if there was any sign or suspicion of rebleeding, and reclipping was performed if necessary and feasible.RESULTS Initial hemostatic rate by clipping was 95%, and rebleeding rate was only 8%.Ultimate hemostatic rates were 87%, 96%, and 93% in the F1a and F1b subgroups, and total cases, respectively. In patients with shock on admission, hemoclipping achieved ultimate hemostasis of 71% and 83% in F1a and F1b subgroups, respectively. Hemostasis reached 100% in patients without shock regardless of hemorrhagic activity being F1a or F1b. The average number of clips used per case was 3.0 (range 2- 5). Spurting bleeders required more clips on average than did oozing bleeders (3.4 versus 2.8 ). We observed no obvious complications, no tissue injury, or impairment of ulcer healing related to hemoclipping.CONCLUSION Endoscopic hemoclip placement is an effective and safe method. With the improvement of the clip and application device,the procedure has become easier and much more efficient. Endoscopic hemoclipping deserves further study in the treatment of bleeding peptic ulcers.

    The patient is an 82 year-old female with a history of osteoarthritis, hypothyroidism and anemia for 14 years (receiving blood transfusions). She was admited to our hospital with a nine months history of malaise, anorexia, fatigue and weakness, associated with intermitten episodes of abdominal pain. She was diagnosed anemia and occult blood positive stools. Physical examination revealed a patient in generally fair condition, obese, with mild edema of lower limbs, no changes in the evaluation of chest, cardiovascular, abdomen, etc. Laboratory data was unremarkable, except for iron deficiency anemia. The upper endoscopy showed duodenal ulcer scar, fundic polyposis and chronic gastritis. Colonoscopy revealed some diverticula, a small sessile polyp and internal hemorrhoids. The diagnosis of obscure gastrointestinal bleeding was made. The CT scan of the abdomen showed gallstones and fatty liver; a radiograph of intestinal transit detected a lesion apparently protruded intestinal loop for distal jejunum; enteroscopy was performed (with one team ball) anterograde and retrograde achieving assess distal jejunum and distal ileum without observing any injuries. The study of capsule endoscopy showed a polypoid tumor intestinal with evidence of having bleeding. Surgery detected the tumor in proximal ileum. The surgical specimen findings showed three tumors 0.7 mm, 10 mm and 15 mm on the proximal ileum. The microscopic examination revealed that these lesions were neuroendocrine tumors (carcinoid). The Ileal carcinoid tumor may rarely presented with obscure gastrointestinal bleeding. PMID:21544161

    Inflammatory fibroid polyp's (IFP) or Vanek tumor of the gastrointestinal tract represents a relatively unusual entity. IFP is an extremely rare cause of upper gastrointestinal bleeding. We report herein a case of a 30-year-old woman who had a gastric IFP complicated by gastrointestinal bleeding and obstructive symptoms. The lesion was mistaken on endoscopic, radiologic examination and in the operating room for a gastrointestinal stromal tumor (GIST). Preoperative endoscopic examination revealed a protruding oval-shaped submucosal lesion (approximately 7 cm in size) of the gastric antrum, with ulceration of the mucosal surface. Multiple endoscopic biopsies were negative for neoplastic changes. Barium meal study disclosed a large tumor in the prepyloric area of the stomach. Presumptive preoperative diagnosis was GIST. Subtotal Bilroth II gastrectomy en bloc with the mass and lymphadenectomy was performed. Surprisingly, the final histological diagnosis was IFP. Postoperative course was uneventful and no recurrences were observed during 4 years follow-up. With reference to case report, the etiology, diagnosis and treatment strategy of IFP will be discussed. This case highlights an unusual presentation of IFP. Although bleeding may represent a rare complication due IFP, it should be considered in the differential diagnosis of upper gastrointestinal hemorrhage of uncertain etiology. PMID:20405696

    BACKGROUND: Few studies have assessed microlfora and their antibiotic sensitivity in normal bile and lithogenic bile with different types of gallstones. METHODS: We performed a case control study of 70 bile samples (35 cholesterol and 35 pigment stones from 51 females and 19 males, aged 21-72 years with a median age of 37 years) from patients who underwent laparoscopic cholecystectomy for uncomplicated cholelithiasis, and 20 controls (14 females and 6 males, aged 33-70 years with a median age of 38 years) who underwent laparotomy and had no gallbladder stone shown by ultrasound scan. The bile samples were aerobically cultured to assess microlfora and their antibiotic susceptibility. The procedures were undertaken under sterile conditions. RESULTS: Thirty-eight (54%) of the 70 patients with gallstones had bacterial isolates. Nine isolates (26%) were from cholesterol stone-containing bile and 29 isolates (82%) from pigment stone-containing bile (P=0.01, t test). Twenty-eight of these 38 (74%) bile samples were shown positive only after enrichment in brain heart infusion medium (BHI) (P=0.02, t test). The overall bacterial isolates from bile samples revealed E. coli predominantly, followed by P. aeruginosa, Enterococcus spp., Klebsiella spp. and S. epidermidis. There were no bacterial isolates in the bile of controls after either direct inoculation or enrichment in BHI. CONCLUSIONS: Bacterial isolates were found in pigment stone-containing bile. Non-lithogenic bile revealed no bacteria, showing an association between gallstone formation and the presence of bacteria in bile. Antibiotic sensitivity patterns of isolated organisms were similar irrespective of the type of stone.

  15. Radiation therapy and arterial infusion chemotherapy for advanced gallbladder cancer

    International Nuclear Information System (INIS)

    The standard therapy is not yet established for the unresectable advanced gallbladder cancer (AGC). Here described is the outcome of authors' therapeutic protocol for AGC during the time Jan., 1989-Dec., 2008. Subjects are 73 patients (M 32/F 41, average age 65 y) with AGC of Stage IV. One shot arterial infusion (AI) of EEP regimen (etoposide (VP16)/4'epiadriamycin (EPIR)/cisplatin (CDDP)) is conducted via hepatic artery proper or common at the first angiography and one week later, external radiation therapy (RT), with about 30-50 Gy/6 fractions (actually, 12-61.6 Gy). AI is weekly done with FP regimen (CDDP/5-fluorouracil (FU)) through the reservoir indwelled in the gastroduodenal artery for 6 months where a metal stent for the stegnosis of bile duct is used if necessary after RT, and in recent days, additionally with biweekly CDDP/gemcitabin (GEM) regimen depending on patient's state after FP. As a result, RT is conducted to 62 cases (RT alone 8 cases), AI, 64 (alone, 10), and RT+AI, 54. Response is found to be 49% (CR 7 cases and PR, 28). Survivals 1- and 3-year are 39 and 6%, respectively, and average survival time, 408 days. Survival rate in (RT+AI) is significantly superior to that in AI alone and in RT alone. Prognosis in patients with jaundice, hepatic or duodenal invasion is significantly inferior to those without the symptom, and in non-responded cases, to responded cases. Complications like hepatic abscess are seen in 4 cases at 6 months after treatment. Four actual case-reports are presented in details with their images. Combination of RT+AI is suggested to be of utility for AGC, of which multi-center trial is awaited with addition of newer anti-cancers developed recently. (K.T.)

    The closed experimental animal model system was used to compare the detectable gastrointestinal (GI) bleeding rates of {sup 99m}Tc-DTPA, {sup 99m}Tc-RBCs and {sup 99m}Tc tin colloid in sheep. The three radiopharmaceuticals were used to detect the upper GI bleeding sites at rates of 0.57 and 0.25 ml/min. At the lower bleeding rate of 0.1 ml/min, both {sup 99m}Tc-DTPA and {sup 99m}Tc-RBCs were successful in detecting the bleeding site. At the lowest rate of 0.07 ml/min only {sup 99m}Tc-DTPA was successful in detecting the bleeding site. The results indicate that {sup 99m}Tc-DTPA is the most useful {sup 99m}Tc radiopharmaceutical for detecting the upper GI bleeding site at the slowest bleeding rate studied. (orig.).

    The preoperative diagnosis of less than ss depth gallbladder cancer is difficult. Its preoperative diagnosis rate was low (27.5%), and even lower with the presence of concomitant gallstone. In the latter case,the diagnosis rate was particularly low when the stones diameter was greater than 1 cm. Gallstones are frequently associated with macromorphologically invasive type of gallbladder cancer and this may be the reason for the lower diagnostic rate. We compared preoperative diagnosis rate of ultrasonography (US), computed tomography (CT) and drip infusion cholecystography (DIC) for each invasion depth. In US, the preoperative diagnosis rate for m depth invasion was 6/16 (37.5%), pm depth was 1/13 (7.7%), and ss depth was 14/41 (34.1%). In CT, its rate for m depth was 3/11 (27.3%), pm depth was 1/10 (10.0%), and ss depth was 11/37 (29.7%). In DIC, its rate for m depth was 3/11 (27.3%), pm depth was 1/10 (10.0%), and ss was depth 1/23 (4.3%). None of the currently used imaging techniques were very accurate in diagnosing gallbladder cancer. Thus, during preoperative work up, if one discovers a gallbladder full of stones, stones of greater than 1 cm in diameter, thickened gallbladder wall, or a non visualized gallbladder with DIC, gallbladder cancer must be highly suspected.

    An 81-year-old man was referred to our institution for evaluation of high fever and a liver tumor that had been detected by ultrasonography. Computed tomography revealed a low-density mass with peripheral ring-like enhancement in S5 of the liver. The liver mass was in contact with the gallbladder, and the boundary between the mass and the gallbladder was unclear. On the suspicion of liver abscess, percutaneous transhepatic drainage was performed. The cavity of the abscess communicated with the gallbladder. Because the cavity had no tendency to reduce in size, we performed surgical resection under a preoperative diagnosis of liver abscess or primary liver carcinoma invading to the gallbladder. Intraoperative findings revealed a liver tumor invading the transverse colon and gallbladder. Subsegmentectomy of S4a and S5 of the liver combined with gallbladder and transverse colon resection was performed. Histopathological findings indicated the growth of a mass forming type intrahepatic cholangiocarcinoma with invasion to the transverse colon and gallbladder, and the pathological stage of the tumor was pT3N0M0, fStage Ⅲ. Thus far, the patient is alive without recurrence 9 months after surgery. Here, we report an extremely rare case of intrahepatic cholangiocarcinoma that invaded other organs and was associated with an intra-tumor abscess. PMID:26805160

  20. The role of 99Tcm-EHIDA hepatobiliary scintigraphy in the estimation of gallbladder motility in patients with liver cirrhosis

    International Nuclear Information System (INIS)

    Objective: To investigate the role of 99Tcm-2,6-diethylacetanilide-iminodiacetic acid (EHIDA) hepatobiliary scintigraphy in the estimation of gallbladder motility in patients with liver cirrhosis. Methods: Liver cirrhosis subjects and normal subjects were included. Patients were further divided into two groups: gallstones group and no gallstone group. Serial hepatobiliary images were taken for 65 min at 1-minute intervals. Two regions of interest (ROIs) were chosen: ROI1, over the entire gallbladder; ROI2, over the entire liver, and time-activity curves were generated for both regions. And then latent period (LP), ejection period (EP), gallbladder ejection fraction (GBEF) and ejection rate (ER) were calculated. Results: Significant differences in GBEF, LP and ER were found between 14 normal subjects and 58 cirrhosis patients. Significant differences in incidence of gallbladder motility abnormality, thickening of gallbladder wall and serum total bile acid (TBA) were found between 15 cirrhosis patients with gallstones and 47 without gallstone. Conclusions: The gallbladder motility function of cirrhosis patients is impaired with the characteristic of impairment of GBEF and ER. 99Tcm-EHIDA hepatobiliary scintigraphy is a noninvasive, safe and valuable method in the diagnosis of gallbladder motility dysfunction in cirrhosis patients.

  1. Endoscopic hemostasis state of the art - Nonvariceal bleeding.

    2016-02-25

    New endoscopic techniques for hemostasis in nonvariceal bleeding were introduced and known methods further improved. Hemospray and Endoclot are two new compounds for topical treatment of bleeding. Initial studies in this area have shown a good hemostatic effect, especially in active large scale oozing bleeding, e.g., tumor bleedings. For further evaluation larger prospective studies comparing the substanced with other methods of endoscopic hemostasis are needed. For localized active arterial bleeding primary injection therapy in the area of ​​bleeding as well as in the four adjacent quadrants offers a good method to reduce bleeding activity. The injection is technically easy to learn and practicable. After bleeding activity is reduced the bleeding source can be localized more clearly for clip application. Today many different through-the-scope (TTS) clips are available. The ability to close and reopen a clip can aid towards good positioning at the bleeding site. Even more important is the rotatability of a clip before application. Often multiple TTS clips are required for secure closure of a bleeding vessel. One model has the ability to use three clips in series without changing the applicator. Severe arterial bleeding from vessels larger than 2 mm is often unmanageable with these conventional methods. Here is the over-the-scope-clip system another newly available method. It is similar to the ligation of esophageal varices and involves aspiration of tissue into a transparent cap before closure of the clip. Thus a greater vascular occlusion pressure can be achieved and larger vessels can be treated endoscopically. Patients with severe arterial bleeding from the upper gastrointestinal tract have a very high rate of recurrence after initial endoscopic treatment. These patients should always be managed in an interdisciplinary team of interventional radiologist and surgeons. PMID:26962402

    To determine the frequencies of histopathological findings in endometrial and endocervical biopsy samples with clinical history of Postmenopausal Bleeding (PMB). Study Design: Descriptive cross-sectional study. Place and Duration of Study: Section of Histopathology, Department of Pathology and Laboratory Medicine, The Aga Khan University Hospital, Karachi, from February 2012 to January 2013. Methodology: A total of 157 consecutive endometrial and endocervical biopsy specimens with history of postmenopausal bleeding were included. After microscopic examination, frequencies of histological findings in different age groups were generated. Chi-square and independent sample t-tests were applied to see whether the difference was significant which was set at p < 0.05. Results: One hundred and twenty-one (77.1%) specimens showed benign pathologies while 36 (22.9%) were malignant. Endometrial polyp was seen in 67 (42.7%) cases followed by endometrial carcinomas in 25 (15.9%), endometrial hyperplasia in 21 (13.4%), cervical carcinoma in 12 (7.6%) and cervical polyps in 9 (5.7%) cases. Ahighly significant increase in the percentage of malignant and pre-malignant lesions was seen with increasing age group (p < 0.001). Mean age of patients with type-2 endometrial carcinoma was higher than type-1 endometrial carcinoma but statistical significance was not observed (70.2 ± 6.5 vs. 61.8 ± 9.1 years respectively, p=0.069). Conclusion: Although benign pathologies were more common in postmenopausal bleeding but the collective proportion of endometrial and cervical malignancies and pre-malignant conditions was quite high. Therefore, PMB should be urgently evaluated for cause and early commencement of treatment. (author)

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

    Actinomycosis should be included in the differential diagnosis when sonography and computed tomography findings show a mass engulfing the stone in the gallbladder and extensive pericholecystic infiltration with extension to neighboring abdominal wall muscle. A ctinomycosis is a chronic suppurative and granulomatous disease that is characterized by the formation of multiple abscesses, draining sinuses, abundant granulation and dense fibrous tissue. The disease is most frequently caused by Actinomyces israelii. These organisms are gram-positive anaerobic bacteria, and are considered opportunistic pathogens associated with infection, trauma or surgery. These events allow them to cross mucosal barriers as these organisms are normally present in healthy individuals, especially in the oral cavity, gastrointestinal tract, and female genital tract. In abdominopelvic actinomycosis, aggressive perilesional infiltration with a tendency to cross fascial planes or boundaries and extend to the abdominal wall has been well described as an important radiologic finding. Actinomycosis of the gallbladder is an extremely rare disease; only 21 cases have been reported in the English literature. Moreover, a diagnosis of actinomycosis of the gallbladder is difficult because this condition can be confused with carcinoma. We report here on a rare case of actinomycosis of the gallbladder that presented as a mass by sonography and computed tomography (CT)

    Full Text Available Abstract Background Breast cancer is usually associated with metastases to lungs, bones and liver. Breast carcinoma metastasizing to the gallbladder is very rare. Case presentation A 59-year-old woman presented with bilateral synchronous breast lesions. A palpable, retroareolar solid lesion of diameter equal to 5 cm was present in the right breast, and a newly developed, non-palpable lesion with microcalcifications (diameter equal to 0.7 cm was present in the upper outer quadrant of the left breast. Modified radical mastectomy was performed on the right breast and lumpectomy after hook-wire localization was performed on the left breast, combined with lymph node dissection in both sides. The pathological examination revealed invasive lobular carcinoma grade II in the right breast and invasive ductal carcinoma grade I in the left breast. Chemotherapy, radiation therapy, trastuzumab and letrozole were appropriately administered. At her 18-month follow-up, the patient was free of symptoms; the imaging tests (chest CT, abdominal U/S, bone scan, biochemical tests, blood cell count and tumor markers were also normal. At the 20th month after surgery however, the patient developed symptoms of cholecystitis and underwent cholecystectomy. The histopathological examination revealed metastasis of the lobular carcinoma to the gallbladder. Conclusion This extremely rare case confirms on a single patient the results of large series having demonstrated the preferential metastasis of lobular breast cancer to the gallbladder. Symptoms of cholecystitis should not be neglected in such patients, as they might indicate metastasis to the gallbladder.

    To evaluate the characteristics of gallbladder polyps 10 mm or larger to predict a neoplasm in US examinations. Fifty-three patients with gallbladder polyps ≥ 10 mm with follow-up images or pathologic diagnosis were included in the retrospective study. All images and reports were reviewed to determine the imaging characteristics of gallbladder polyps. Univariate and multivariate analyses were used to evaluate predictors for a neoplastic polyp. A neoplastic polyp was verified in 12 of 53 patients and the mean size was 13.9 mm. The univariate analysis revealed that adjacent gallbladder wall thickening, larger size (≥15 mm), older age (≥57 years), absence of hyperechoic foci in a polyp, CT visibility, sessile shape, a solitary polyp, and an irregular surface were significant predictors for a neoplastic polyp. In the multivariate analysis, larger size (≥15 mm) was a significant predictor for a neoplastic polyp. A polyp size ≥15 mm was the strongest predictor for a neoplastic polyp with US. The hyperechoic foci in a polyp and CT visibility would be useful indicators for the differentiation of a neoplastic polyp, in addition to the established predictors. (orig.)

    AIM: To study the role of Fas and Fas ligand (FasL) in biological behaviors of gallbladder carcinoma, and their correlated action and mechanism in tumor escape.METHODS: Streptavidin-biotin-peroxidase immunohistochemistry technique was used to study the expression of Fas and FasL protein in 26 gallbladder carcinoma tissues,18 gallbladder adenoma tissues, 3 gallbladder dysplasia tissues and 20 chronic cholecystitis tissues. Apoptosis of the infiltrating lymphocytes in these tissues was studied by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) method. Expression of both proteins and apoptosis of the tumor infiltrating lymphocytes in cancer tissues of primary foci was compared with clinicopathological features of gallbladder carcinoma.RESULTS: The positive rates of Fas were not significantly different among carcinoma, adenoma, dysplasia and chronic cholecystitis. The positive rate of FasL in carcinoma was significantly higher than that in chronic cholecystitis (x2 = 4.89, P<0.05). The apoptotic index (AI) in carcinoma was significantly higher than that in adenoma (t'= 4.19, P<0.01) and chronic cholecystitis (t'= 8.06, P<0.01). The AI was significantly lower in well-differentiated carcinoma and Nevin Ⅰ-Ⅲ carcinoma than that in poorly-differentiated carcinoma (t'= 2.63, P<0.05) and Nevin Ⅳ-Ⅴ carcinoma(t'= 3.33, P<0.01). The confidence interval (CI) ofinfiltrating lymphocytes in adenoma, chronic cholecystitis, well-differentiated carcinoma and Nevin Ⅰ-Ⅲ carcinoma wasvery significantly lower than that in carcinoma (t' = 6.99,P<0.01), adenoma (t' = 3.66, P<0.01), poorly-differentiated carcinoma (t' = 5.31, P<0.01) and Nevin Ⅳ-Ⅴ carcinoma(t' = 3.76, P<0.01), respectively. The CI of apoptosis of infiltrating lymphocytes in well-differentiated carcinoma was significantly lower than that in poorly-differentiated carcinoma (t = 2.52, P<0.05), and was not significantly lower in Nevin Ⅰ-Ⅲ carcinoma than

    The existing animal models used for the simulation of acute gastrointestinal bleedings are usually non-survival models. We developed and evaluated a new porcine model (domestic pig, German Landrace) in which the animal remains alive and survives the artificial bleeding without any cardiovascular impairment. This consists of a bleeding catheter which is implanted into the stomach, then subcutaneously tunnelled from the abdomen to the neck where it is exteriorized and fixed with sutures. Using the injection of porcine blood, controllable and reproducible acute upper gastrointestinal bleeding can be simulated while maintaining normal gastrointestinal motility and physiology. Depending on the volume of blood applied through the gastric catheter, the bleeding intensity can be varied from traces of blood to a massive haemorrhage. This porcine model could be valuable, e.g. for testing the efficacy of new bleeding diagnostics in large animals before human use. PMID:26306615

    2016-01-01

    Direct oral anticoagulants (DOACs) offer clinical advantages over warfarin, such as minimal medication and food interactions and fixed dosing without the need for routine monitoring of coagulation status. As with all anticoagulants, bleeding, either spontaneous or provoked, is the most common complication. The long-term use of these drugs is increasing, and there is a crucial need for emergency medicine service professionals to understand the optimal management of associated bleeding. This review aims to describe the indications and pharmacokinetics of available DOACs; to discuss the risk of bleeding; to provide a treatment algorithm to manage DOAC-associated emergency bleeding; and to discuss future directions in bleeding management, including the role of specific reversal agents, such as the recently approved idarucizumab for reversal of the direct thrombin inhibitor dabigatran. Because air medical personnel are increasingly likely to encounter patients receiving DOACs, it is important that they have an understanding of how to manage patients with emergent bleeding.

    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

    AIM: To identify clinical parameters, and develop an Upper Gastrointesinal Bleeding (UGIB) Etiology Score for predicting the types of UGIB and validate the score.METHODS: Patients with UGIB who underwent endoscopy within 72 h were enrolled. Clinical and basic laboratory parameters were prospectively collected.Predictive factors for the types of UGIB were identified by univariate and multivariate analyses and were used to generate the UGIB Etiology Score. The best cutoff of the score was defined from the receiver operating curve and prospectively validated in another set of patients with UGIB.RESULTS: Among 261 patients with UGIB, 47 (18%) had variceal and 214 (82%) had non-variceal bleeding.Univariate analysis identified 27 distinct parameters significantly associated with the types of UGIB. Logistic regression analysis identified only 3 independent factors for predicting variceal bleeding;previous diagnosis of cirrhosis or signs of chronic liver disease (OR 22.4, 95% CI 8.3-60.4, P < 0.001), red vomitus (OR4.6, 95% CI 1.8-11.9, P = 0.02), and red nasogastric (NG) aspirate (OR 3.3, 95% CI 1.3-8.3, P = 0.011).The UGIB Etiology Score was calculated from (3.1 x previous diagnosis of cirrhosis or signs of chronic liver disease) + (1.5 × red vornitus) + (1.2 × red NG aspirate), when 1 and 0 are used for the presence and absence of each factor, respectively. Using a cutoff ≥ 3.1, the sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) in predicting variceal bleeding were 85%, 81%,82%, 50%, and 96%, respectively. The score was prospectively validated in another set of 195 UGIB cases (46 variceal and 149 non-variceal bleeding). The PPV and NPV of a score ≥3.1 for variceal bleeding were 79% and 97%, respectively.CONCLUSION: The UGIB Etiology Score, composed of 3 parameters, using a cutoff ≥ 3.1 accurately predicted variceal bleeding and may help to guide the choice of initial therapy for UGIB before endoscopy.

    Full Text Available Leeches are blood-sucking hermaphroditic parasites that attach to vertebrate hosts, bite through the skin, and suck out blood. When leeches feed, they secrete an anticoagulant (hirudin, which helps them get a full meal of blood. This is the first report of leech removal from external auditory canal. Previous leech involvement cases were explained in nasopharynx, larynx, pharynx, eye, and gastrointestinal tract. Prominent sign of all cases was active bleeding from the leech attachment site; that stopped with leech removal. A 24-year-old man was presented to Al-Zahra hospital with left otorrhagia and otalgia from 2 days ago. After suction of ear a small soft foreign body was seen in the external ear near the tympanic membrane, then the ear filled with glycerine phenice, the patient explained decreased movement of foreign body. Four hours later the bloody discharge stopped and otalgia decreased. After suction of clots, a leech was extruded from external auditory canal by alligator. Leech infestation is a rare cause of otorrhagia and should be suspected in the endemic region in all of unusual bleeding; it can be diagnosed and treated by exact inspection and removal.

    Nonvariceal upper gastrointestinal (UGI) bleeding is a frequent complication with significant morbidity and mortality. Although endoscopic hemostasis remains the initial treatment modality, severe bleeding despite endoscopic management occurs in 5-10% of patients, necessitating surgery or interventional embolotherapy. Endovascular embolotherapy is now considered the first-line therapy for massive UGI bleeding that is refractory to endoscopic management. Interventional radiologists need to be familiar with the choice of embolic materials, technical aspects of embolotherapy, and the factors affecting the favorable or unfavorable outcomes after embolotherapy for UGI bleeding.

    Upper gastrointestinal (GI) bleeding is a serious complication that sometimes occurs after percutaneous radiologic gastrostomy (PRG). We evaluated the incidence of bleeding complications after a PRG and its management including transcatheter arterial embolization (TAE). We retrospectively reviewed 574 patients who underwent PRG in our institution between 2000 and 2010. Eight patients (1.4%) had symptoms or signs of upper GI bleeding after PRG. The initial presentation was hematemesis (n = 3), melena (n = 2), hematochezia (n = 2) and bloody drainage through the gastrostomy tube (n = 1). The time interval between PRG placement and detection of bleeding ranged from immediately after to 3 days later (mean: 28 hours). The mean decrease in hemoglobin concentration was 3.69 g/dL (range, 0.9 to 6.8 g/dL). In three patients, bleeding was controlled by transfusion (n = 2) or compression of the gastrostomy site (n = 1). The remaining five patients underwent an angiography because bleeding could not be controlled by transfusion only. In one patient, the bleeding focus was not evident on angiography or endoscopy, and wedge resection including the tube insertion site was performed for hemostasis. The other four patients underwent prophylactic (n = 1) or therapeutic (n = 3) TAEs. In three patients, successful hemostasis was achieved by TAE, whereas the remaining one patient underwent exploration due to persistent bleeding despite TAE. We observed an incidence of upper GI bleeding complicating the PRG of 1.4%. TAE following conservative management appears to be safe and effective for hemostasis.

    Despite conventional treatment modalities, gallbladder cancer (GBC) remains a highly lethal malignancy. Prognostic biomarkers and effective adjuvant immunotherapy for GBC are not available. In the recent past, immunotherapeutic approaches targeting tumor associated inflammation have gained importance but the mediators of inflammatory circuit remain unexplored in GBC patients. In the current prospective study, we investigated the role of IL17 producing TCRγδ(+) (Tγδ17), CD4(+) (Th17), CD8(+) (Tc17) and regulatory T cells (Tregs) in pathogenesis of GBC. Analysis by multi-color flow cytometry revealed that compared to healthy individuals (HI), Tγδ17, Th17 and Tc17 cells were increased in peripheral blood mononuclear cells (PBMCs) and tumor infiltrating lymphocytes (TIL) of GBC patients. Tregs were decreased in PBMCs but increased in TILs of GBC patients. The suppressive potential of Tregs from GBC patients and HI were comparable. Serum cytokines profile of GBC patients showed elevated levels of cytokines (IL6, IL23 and IL1β) required for polarization and/or stabilization of IL17 producing cells. We demonstrated that Tγδ17 cells migrate toward tumor bed using CXCL9-CXCR3 axis. IL17 secreted by Tγδ17 induced productions of vascular endothelial growth factor and other angiogenesis related factors in GBC cells. Tγδ17 cells promote vasculogenesis as studied by chick chorioallantoic membrane assay. Survival analysis showed that Tγδ17, Th17 and Treg cells in peripheral blood were associated with poor survival of GBC patients. Our findings suggest that Tγδ17 is a protumorigenic subtype of γδT cells which induces angiogenesis. Tγδ17 may be considered as a predictive biomarker in GBC thus opening avenues for targeted therapies. PMID:27062572

It is characterized by a poor prognosis and its resistance to radio and chemotherapy. There is an urgent need to develop novel therapeutic alternatives for the treatment of gallbladder carcinoma. The mammalian target of the rapamycin (mTOR signaling pathway is activated in about 50% of human malignancies, and its role in gallbladder carcinoma has previously been suggested. In the present study, we investigated the phosphorylation status of the mTOR substrate p70S6K in preneoplastic and neoplastic gallbladder tissues and evaluated the effect of three mTOR inhibitors on cell growth and migration in gallbladder carcinoma cell lines.Methods: Immunohistochemical staining of phospho-p70S6K was analyzed in 181 gallbladder carcinoma cases, classified according to lesion type as dysplasia, early carcinoma, or advanced carcinoma. Protein expression of AKT/mTOR members was also evaluated in eight gallbladder carcinoma cell lines by Western blot analysis. We selected two gallbladder carcinoma cell lines (G415 and TGBC-2TKB to evaluate the effect of rapamycin, RAD001, and AZD8055 on cell viability, cell migration, and protein expression.Results: Our results showed that phospho-p70S6K is highly expressed in dysplasia (66.7%, 12/18, early cancer (84.6%, 22/26, and advanced cancer (88.3%, 121/137.

We show here that the gallbladder microenvironment modulates the production of transforming growth factor (TGF)-beta1, a multifunctional cytokine that functions as an endogenous anti-angiogenic and anti-tumor factor in a cranial window preparation. We found that a wide variety of human gallbladder tumors express TGF-beta1 irrespective of histologic type. We implanted a gel impregnated with basic fibroblast growth factor or Mz-ChA-2 tumor in the cranial windows of mice without tumors or mice with subcutaneous or gallbladder tumors to study angiogenesis and tumor growth at a secondary site. Angiogenesis, leukocyte-endothelial interaction in vessels and tumor growth in the cranial window were substantially inhibited in mice with gallbladder tumors. The concentration of TGF-beta1 in the plasma of mice with gallbladder tumors was 300% higher than that in the plasma of mice without tumors or with subcutaneous tumors. In contrast, there was no difference in the plasma levels of other anti- and pro-angiogenic factors. Treatment with neutralizing antibody against TGF-beta1 reversed both angiogenesis suppression and inhibition of leukocyte rolling induced by gallbladder tumors. TGF-beta1 also inhibited Mz-ChA-2 tumor cell proliferation. Our results indicate that the production of anti-angiogenesis/proliferation factors is regulated by tumor-host interactions. PMID:10502827

    Functional disorders of platelets can involve any aspect of platelet physiology, with many different effects or outcomes. These include platelet numbers (thrombocytosis or thrombocytopenia); changes in platelet production or destruction, or capture to the liver (Ashwell receptor); altered adhesion to vascular injury sites and/or influence on hemostasis and wound healing; and altered activation or receptor functions, shape change, spreading and release reactions, procoagulant and antifibrinolytic activity. Procoagulant membrane alterations, and generation of thrombin and fibrin, also affect platelet aggregation. The above parameters can all be studied, but standardization and quality control of assay methods have been limited despite several efforts. Only after a comprehensive clinical bleeding assessment, including family history, information on drug use affecting platelets, and exclusion of coagulation factor, and tissue deficits, should platelet function testing be undertaken to confirm an abnormality. Current diagnostic tools include blood cell counts, platelet characteristics according to the cell counter parameters, peripheral blood smear, exclusion of pseudothrombocytopenia, whole blood aggregometry (WBA) or light transmission aggregometry (LTA) in platelet-rich plasma, luminescence, platelet function analysis (PFA-100) for platelet adhesion and deposition to collagen cartridges under blood flow, and finally transmission electron microscopy to exclude rare structural defects leading to functional deficits. The most validated test panels are included in WBA, LTA, and PFA. Because platelets are isolated from their natural environment, many simplifications occur, as circulating blood and interaction with vascular wall are omitted in these assays. The target to reach a highly specific platelet disorder diagnosis in routine clinical management can be exhaustive, unless needed for genetic counseling.

    In most patients with upper gastrointestinal (GI) bleeding, endoscopy will locate the site and cause of bleeding, and also provide an opportunity for local therapy. The cause of lower GI bleeding is often difficult to attribute, even when pathology is found by colonoscopy or barium enema. Nuclear medicine techniques can be used to identify the site of bleeding in those patients in whom the initial diagnostic procedures are negative or inconclusive. Methods using transient labelling of blood (e.g. [sup 99]Tc[sup m]-sulphur colloid) produce a high target-to-background ratio in positive cases, give quick results and localize bleeding sites accurately, but depend upon bleeding being active at the time of injection. Techniques using stable blood labelling (e.g. [sup 99]Tc[sup m]-labelled red blood cells) may be positive even with intermittent bleeding but may take several hours to produce a result and are less precise in localization. The most useful application is in patients with recurrent or prolonged bleeding, those with inconclusive endoscopy or barium studies, and those who are high-risk surgical candidates. (author).

    There has been a concern that major bleeding events (MBE) on direct-acting oral anticoagulants (DOACs) will be more difficult to manage than on vitamin K antagonists. Patients with cancer and DOAC-associated bleeding may be even more of a challenge to manage. We therefore reviewed the literature on bleeding in patients with cancer on DOACs. In addition, we performed an analysis of individual patient data from 5 phase III trials on treatment with dabigatran with focus on those with cancer. In 6 randomized trials the risk of MBE in patients with cancer was similar on treatment with DOACs compared to vitamin K antagonists. Bleeding was in the majority of patients managed with supportive therapy alone. In the individual patient data analysis there were no significant differences in use of hemostatic products, transfusion of red cells, effectiveness of management, bleeding-related mortality or 30-day all-cause mortality between patients with cancer treated with dabigatran or with warfarin. Local hemostatic therapy, including resection of the cancer site was more common in patients with gastrointestinal bleeding with cancer than among those without cancer. We conclude that management of bleeding in patients with cancer and on a DOAC does not pose a greater challenge than management of bleeding in patients without cancer. PMID:27067968

    Obscure gastrointestinal bleeding is still a clinical challenge for gastroenterologists. The recent development of novel technologies for the diagnosis and treatment of different bleeding causes has allowed a better management of patients, but it also determines the need of a deeper comprehension of pathophysiology and the analysis of local expertise in order to develop a rational management algorithm. Obscure gastrointestinal bleeding can be divided in occult, when a positive occult blood fecal test is the main manifestation, and overt, when external sings of bleeding are visible. In this paper we are going to focus on overt gastrointestinal bleeding, describing the physiopathology of the most usual causes, analyzing the diagnostic procedures available, from the most classical to the novel ones, and establishing a standard algorithm which can be adapted depending on the local expertise or availability. Finally, we will review the main therapeutic options for this complex and not so uncommon clinical problem.

  17. Scintigraphic detection of gastrointestinal bleeding: a review of current methods

    International Nuclear Information System (INIS)

    Recent experience with radionuclide imaging has provided the clinician with several techniques to noninvasively detect and locate sources of gastrointestinal hemorrhage. These tests can be rapidly performed and often in an ICU setting. One method used Tc-99m sulfur colloid which, in an animal model, has been shown to detect acute bleeding at rates as low as 0.1 ml/min. However, because the tracer remains in the blood for a short period of time, it may be suboptimal for identifying patients with intermittent bleeding. Tc-99m red cells is a tracer that remains within the blood and permits detection of both acute and intermittent bleeding. With tagged red cells, sites of bleeding from both the upper and lower gastrointestinal tract can be found. Both of these techniques can provide important information in the patient with suspected active gastrointestinal bleeding and aid the clinician in more effective management including the use of invasive diagnostic and therapeutic techniques

    OBJECTIVES: Lower gastrointestinal (GI) bleeding is a well-known symptom of colorectal cancer (CRC). Whether incident GI bleeding is also a marker of other GI cancers remains unclear. METHODS: This nationwide cohort study examined the risk of various GI cancer types in patients with lower GI...... bleeding. We used Danish medical registries to identify all patients with a first-time hospital diagnosis of lower GI bleeding during 1995-2011 and followed them for 10 years to identify subsequent GI cancer diagnoses. We computed absolute risks of cancer, treating death as a competing risk, and calculated...... standardized incidence ratios (SIRs) by comparing observed cancer cases with expected cancer incidence rates in the general population. RESULTS: Among 58,593 patients with lower GI bleeding, we observed 2,806 GI cancers during complete 10-year follow-up. During the first year of follow-up, the absolute GI...

    The conclusions drawn from a prospective survey of 500 patients examined by cholecystography (OCG) and ultrasound (UCG) are presented. First, both procedures were found to be highly accurate in detecting calculi, with false-negative rates of 1%. Secondly, if OCG is abandoned in favour of UCG, most acalculous adenomyomatosis (and many polyps) will not be diagnosed. If acalculous as well as calculous disease is regarded as clinically important, fluoroscopic OCG is the examination of choice. However, if a clinician wishes solely to find or exclude stones the investigations are equally accurate. Thirdly, since some calculi and some acalculous disease will be missed by either technique, serious consideration should be given to the further investigation of all gallbladders considered normal by either examination. A protocol is described which, though unorthodox, enables a decision on the status of the gallbladder to be made on a single visit to the radiology department. PMID:6141345

  20. Clinical study of CT virtual endoscopy in diagnosing polyps of the gallbladder

    International Nuclear Information System (INIS)

    Objective: To evaluate the ability and clinical application of CT virtual endoscopy on polyps of the gallbladder. Methods: CT virtual endoscopy findings of 32 patients with polyps of the gallbladder proved pathologically were presented by using oral iodine contrast, and compared with color Doppler ultrasound. Results: The accuracy rate of color Doppler ultrasound and CTVEGB were 96.9% (93/96) and 93.8% (90/96) respectively (x2 = 0.466, P > 0.05). CTVEGB could more correctly demonstrate the surface details of polyps which were viewed in a 3D fashion in any projection than ultrasound. CTVEGB corresponded well with color Doppler ultrasound and operation and pathology in demonstrating the size, configuration and location of the lesions. Conclusion: CTVEGB is a noninvasive and accurate procedure, which has a important value in clinic applications

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

    Myxidium trachinorum sp. nov. is described from the gallbladder of the lesser weever fish Echiichthys vipera. Pseudoplasmodia attach themselves to the gallbladder epithelium by filose processes, which are inserted between host cells. Pseudoplasmodia undergo endogenous cell formation at the secondary and tertiary levels. In the proliferative cycle, primary and endogenous cells are packed with digestive vacuoles formed by phagocytosis. In the sporogonic cycle the pseudoplasmodium becomes a pericyte enclosing two secondary cells (lacking digestive vacuoles) in a vacuole. These give rise to five cells each two valvogenic, two capsulogenic and a binucleate sporoplasm, which mature into spores. Comparison of the disporic M. trachinorum with polysporic species of Myxidium revealed significant differences in plasmodial ultrastructure, especially their attachments to host cells, surface characteristics and mode of nutrition, and in formation of generative cells. These suggest that the genus Myxidium may require revision. PMID:10540952

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

    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.

    International Nuclear Information System (INIS)

    Gas-cooled reactors, using packed beds of small diameter coated fuel particles have been proposed for compact, high-power systems. The particulate fuel used in the tests was 800 microns in diameter, consisting of a thoria kernel coated with 200 microns of pyrocarbon. Typically, the bed of fuel particles was contained in a ceramic cylinder with porous metallic frits at each end. A dc voltage was applied to the metallic frits and the resulting electric current heated the bed. Heat was removed by passing coolant (helium or hydrogen) through the bed. Candidate frit materials, rhenium, nickel, zirconium carbide, and zirconium oxide were unaffected, while tungsten and tungsten-rhenium lost weight and strength. Zirconium-carbide particles were tested at 2000 K in H2 for 12 hours with no visible reaction or weight loss

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

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

    International Nuclear Information System (INIS)

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

    AIM:To observe and compare the effects of phytoestrogen genistein,resveratrol and 17β-estradiol on the tonic contraction and the phasic contraction of isolated gallbladder muscle strips and to study the underlying mechanisms.METHODS:Isolated strips of gallbladder muscle from guinea pigs were suspended in organ baths containing Kreb's solution,and the contractilities of strips were measured before and after incubation with genistein,resveratrol and 17β-estradiol respectively.RESULTS:Similar to 17β-estradiol,genistein and resveratrol could dose-dependently inhibit the phasic contractile activities,they decreased the mean contractlie amplitude and the contractlie frequencies of gallbladder muscle strips,and also produced a marked reduction in resting tone.The blocker of estrogen receptor ICI 182780 failed to alter the inhibitory effects induced by genistein and resveratrol,but potassium bisperoxo(1,10 phenanthroline)oxovanadate bpV(phen),a potent protein tyrosine phosphatase inhibitor,markedly attenuated the inhibitory effects induced by genistein and resveratrol.In calcium-free Kreb's solution containing 0.01 mmol/L egtazic acid(EGTA),genistein and resveratrol inhibited the first phasic contraction induced by acetylcholine(Ach),but did not affect the second contraction induced by CaCl2.In addition,genistein,resveratrol and 17β-estradiol also could reduce the contractile responses of Ach and KCI,and shift their cumulative concentration-response curves rightward.CONCLUSION:Phytoestrogen genistein and resveratrol can directly inhibit the contractile activity of isolated gallbladder muscle both at rest and in response to stimulation.The mechanisms responsible for the inhibitory effects probably due mainly to inhibition of tyrosine kinase,Ca2+ influx through potential-dependent calcium channels(PDCs)and Ca2+ release from sarcoplasmic reticulum(SR),but were not related to the estrogen receptors.

    We describe the successful isolation and maintenance of primary cultures of dog gallbladder epithelial cells. The surgically removed gallbladder was treated with trypsin/EDTA for 45 minutes and epithelial cells were collected and resuspended in Eagle's minimum essential medium with 10% fetal calf serum, and plated on Vitrogen-coated culture dishes. Each gallbladder yielded approximately 12 to 15 x 10{sup 6} columnar epithelial cells, greater than 95% of which were viable by trypan blue exclusion. In culture, cells maintained their polarity. They were arranged and grew in small and tight clusters that coalesced at confluency. When examined using transmission electron microscopy, prominent and numerous microville were identified on the apical portion of the plasma membrane. Cells were connected by well-formed desmosomes. Scanning electron microscopy revealed clusters of polyhedral cells with numerous papillary projections. Immunohistochemical studies demonstrated uniform staining of cells to keratin 35BH11 and AE1. Histochemical studies were positive for gamma-glutamyl transpeptidase and negative for glucose-6-phosphatase and albumin. Cells incorporated ({sup 3}H)uridine into intracellular proteins and ({sup 14}C)glucosamine into tissue and secreted mucous glycoproteins linearly over 2 to 24 hours. Flow cytometry studies demonstrated a consistent and reproducible number of cells (10 to 12%) at S-phase. However, the number of cells at S-phase was dramatically reduced to almost negligible as cells reached confluency. This method of culturing primary dog gallbladder epithelial cells is highly reproducible and reliable. These cells preserve their state of differentiation, polarity, histochemical and immunohistochemical profile, morphologic, and metabolic integrity with repeated passaging or after being frozen.

  17. Calculous cholecystitis and hepatic cirrhosis as sonographic co-confounders for gallbladder evaluation

    International Nuclear Information System (INIS)

    To compare the sonographic features of gallbladder in symptomatic calculous cholecystitis and cirrhosis with silent cholelithiasis. Two hundred adult patients of both genders were studied after dividing into two groups. Group A had clinically suspected calculous cholecystitis and group B had patients from outpatient department and medical wards with clinical diagnosis of cirrhosis, with incidentally diagnosed cholelithiasis. The sonographic features of gallbladder were determined and compared. Significance was computed for the sonographic variables including morphological features as well as demographic features by Chi square and t-test, keeping significance at p<.001 Group A (with calculous cholecystitis) had 100 patients with mean age of 47+-3.2 years with 71 females. Group B (cirrhosis with silent cholelithiasis) comprised of 100 patients with mean age of 38 +-4.2 years with 58 females. Among them, 54 were hepatitis C virus(HCV) positive, 38 had positive serology for Hepatitis B virus (HBV) positive and 08 had positive serology for both. Both groups had more multiple than single calculi. The average size of the largest calculus was 1.5 cm in group A and 1.2 cm in the group B. The mean gallbladder wall thickness was greater in cirrhotic than in the other group (4.9 vs. 4.2 cm, p-value 0.7). Gallbladder wall irregularity was significantly more common in group B than in group A (57 vs. 25 mm, p=0.001). The pericholecystic fluid layer thickness was significantly greater in the cirrhotic group (18.5 +7.1 vs. 5.7 +1.8 mm, p<0.001). Positive sonographic Murphy's sign was positive in 89% calculous cholecystitis cases and 77% of the cirrhotic group. (author)

    Apparent streaming potentials were elicited across Necturus gallbladder epithelium by addition or removal of sucrose from the apical bathing solution. In NaCl Ringer's solution, the transepithelial voltage (Vms) change (reference, basolateral solution) was positive with sucrose addition and negative with sucrose removal. Bilateral Cl- removal (cyclamate replacement) had no effect on the polarity or magnitude of the Vms change elicited by addition of 100 mM sucrose. In contrast, bilateral Na+ ...

    We have developed a cell culture of guinea pig gallbladder epithelial cells with which to study ion transport. When grown on permeable supports, the cultured epithelia developed a transepithelial resistance (Rt) of ∼500 Ω·cm2. The epithelial cell origin of the cell culture was further confirmed by immunocytochemical localization of cytokeratin. Ionomycin and forskolin increased transepithelial voltage and short-circuit current (Isc) and decreased Rt. The response to ionomycin was transient, w...

    Space flight has been shown to result in altered immune responses. The current study was designed to investigate this possibility by using the bed rest model of some space flight conditions. A large number of women are included as subjects in the study. The hypothesis being tested is: 60 days head-down tilt bed rest of humans will affect the immune system and resistance to infection. Blood, urine and saliva samples will be obtained from bed rest subjects prior to, at intervals during, and after completion of 60 days of head-down tilt bed rest. Leukocyte blastogenesis, cytokine production and virus reactivation will be assessed. The ability of the subjects to respond appropriately to immunization with the neoantigen bacteriophage φX-174 will also be determined. Bed rest is being carried out at MEDES, Toulouse France, and the University of Texas Medical Branch, Galveston, TX. The studies to be carried out in France will also allow assessment of the effects of muscle/bone exercise and nutritional countermeasures on the immune system in addition to the effects of bed rest.

    Monoclonal antibodies raised by injecting Necturus gallbladder cells into mice were tested for their ability to inhibit the apical chloride conductance induced by elevation of cellular cAMP. Five of these monoclonal antibodies bound to the apical cells, as shown by indirect immunofluorescence microscopy, and inhibited the chloride conductance; one antibody that bound only to subepithelial smooth muscle, by indirect immunofluorescence microscopy, showed no inhibition of chloride transport. The channel or a closely related molecule is present in the membrane whether or not the pathway is open, since, in addition to inhibiting the conductance of the open channel, the antibody also bound to the membrane in the resting state and prevented subsequent opening of the channel. The antibody was shown to recognize, by ELISA, epitopes from the Necturus gallbladder and small intestine. Finally, by Western blot analysis of Necturus gallbladder homogenates, the antibody was shown to recognize two protein bands of Mr 219,000 and Mr 69,000. This antibody should permit isolation and characterization of this important ion channel.

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

    A 58-year-old woman was referred to our hospital with high fever and right upper abdominal pain. Abdominal computed tomography (CT) revealed a bulky tumor of the gallbladder with liver invasion, metastases to para-aortic lymph nodes, and extensive infiltration to Glisson's sheath. The tumor was initially considered to be unresectable locally advanced gallbladder carcinoma with inflammation, and she received 6 courses of chemotherapy with gemcitabine plus cisplatin. Subsequently, the inflammation was extinguished, and CT showed the main tumor shrunk and the Glisson's sheath infiltration disappeared; however, a liver metastasis existed in segment 5. Thus, S4a plus S5 hepatic segmentectomy with extrahepatic bile duct resection and regional and para-aortic lymphadenectomy was performed. The pathological diagnosis was pT3a, pN1, pM1 (Hep, LYM), fStage ⅣB. Curative resection was then performed. If selected according to their response to downsizing chemotherapy, conversion therapy might therefore be an effective multidisciplinary treatment for patients with initially unresectable locally advanced gallbladder carcinoma.

    Full Text Available Context Autoimmune pancreatitis is a rare variant of chronic pancreatitis characterized by pancreatic ductal narrowing and pancreatic parenchymal edema on computed tomography and rarely with intermittent attacks of abdominal pain. Recently, it has been found to be a systemic disease with lymphoplasmacytic infiltration that has been associated with several autoimmune diseases and described in multiple organs including the extrahepatic bile duct, liver and gallbladder. Case report We describe the clinical, radiographic and histopathologic aspects of a patient who presented with synchronous masses in the pancreatic head and gallbladder. Postoperatively, the patient's jaundice subsided and IgG4 levels, which were drawn one week postoperatively, were all within normal limits. Nonetheless, immunohistochemical staining for IgG4 was positive. Conclusion Autoimmune pancreatitis is the most common benign entity identified in patients that underwent pancreaticoduodenectomy for presumed pancreatic adenocarcinoma. Our patient with autoimmune pancreatitis presented with simultaneous inflamematory masses in the gallbladder and pancreatic head, an association not previously reported. Preoperative evaluation of IgG4 or autoantibody levels may have obviated the need for an operation. Therefore, we have begun screening for elevated serum IgG4 concentrations to identify patients with possible autoimmune pancreatitis who present without definitive pathological or radiographic evidence for malignancy. If preoperative diagnosis is not made, immunohistochemical staining of pathology specimens can confirm the diagnosis.

    A 75-year-old man presented to his physician with weakness, anorexia, and constant right upper quadrant pain. He underwent a laparoscopic cholecystectomy, which was converted to an open cholecystectomy due to presumed adhesions. Direct examination of the liver was negative for masses or lesions. A CT scan was negative for masses or nodules. The gallbladder was 8.5 x 2.5 cm(2), with a diffusely thick wall measuring 2.5 cm. Microscopic examination showed a monomorphic tumor consisting of cells with increased nuclear:cytoplasmic ratio and occasional nucleoli, infiltrating the entire gallbladder uniformly. The tumor cells that reacted to antibodies directed against HepPar1, CAM 5.2, CK19 and scattered cells were immunoreactive for CD117, CD34, and CD56. This immunohistochemical profile suggested a 'hepatocellular progenitor cell tumor of the gall bladder'. This report is, to our knowledge, the first such case of a tumor of this cell type reported in the gallbladder. In addition, we present a review of the literature. PMID:15696116

  10. Carcinoma in situ in a 7 mm gallbladder polyp: Time tochange current practice?

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    Detection of polypoid lesions of the gallbladder isincreasing in conjunction with better imaging modalities.Accepted management of these lesions depends on theirsize and symptomatology. Polyps that are symptomaticand/or greater than 10 mm are generally removed,while smaller, asymptomatic polyps simply monitored.Here, a case of carcinoma-in-situ is presented in a 7mm gallbladder polyp. A 25-year-old woman, who hadundergone a routine cholecystectomy, was found tohave an incidental 7 mm polyp containing carcinomain situ . She had few to no risk factors to alert to hercondition. There are few reported cases of cancertransformation in gallbladder polyps smaller than 10 mmreported in the literature. The overwhelming consensus,barring significant risk factors for cancer being present,is that such lesions should be monitored until theybecome symptomatic or develop signs suspicious formalignancy. In our patient's case this could have ledto the possibility of missing a neoplastic lesion, whichcould then have gone on to develop invasive cancer. Asgallbladder carcinoma is an aggressive cancer, this mayhave led to a tragic outcome.

    To assess the morphological features and the accuracy of T staging images in surgically- proven gallbladder cancers, retrospectively. Images of 59 surgically-proven gallbladder cancers were reviewed. Morphologic features, shape, size of tumors and the presence of stones or sludge within the images were evaluated and correlated with surgicopathologic findings. Polypoid masses were shown in 49 cases (83%). The sizes of tumors were well correlated with surgicopathologic T-stage. With ROC evaluation, the size cutoff point to differentiate the {<=} T1 versus {>=} T2 lesions was 2.4 cm. Stones or sludge were found in 25 cases (42%). The positive predictive value, negative predictive value, sensitivities, specificities, and accuracy of the ability to differentiate the {<=} T1 versus {>=} T2 lesions were 75%, 86%, 46%, 96%, 85% and those of the ability to differentiate {<=} T2 versus {>=} T3 lesions were 89%, 49%, 45%, 90%, and 61%, respectively. Image analysis showed that polypoid mass and wall thickening were major findings. With this in mind, polypoid mass shows the possibility of gallbladder cancer originating from adenoma, even if the size is larger than 2 or 2.4 cm, the surgicopathologic stage could be low. Moreover, the accuracy of image based T stage on pericholecystic infiltration and wall thickening was low.

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

    Full Text Available Introduction: Bleeding from gums is a common feature in periodontitis patient. But abnormal bleeding from the gingiva or other areas of the oral mucosa that is difficult to control is an important clinical sign suggesting a hematological disorder. Case Report: A-40-year old male patient reported to our clinic with the chief complaint of acute gingival bleeding. There was continuous bleeding, fever since 3-4 days with weakness, retro orbital pain, and severe backache. Patient gave a history of bleeding from gums for last 24 hrs. His blood profile revealed; platelet count of 36,000, total wite blood cell (WBC count of 6000/cumm, differential leukocyte count (DLC (P45, L53, E2, and hemoglobin 12 g/dL. Patient sera was positive for dengue non-structural protein-1 antigen, anti-dengue immunoglobulin M (IgM, and anti-dengue immunoglobulin G (IgG antibodies. Discussion: Here is a case report capable of changing our vision that acute gingival bleeding can also occur in dengue fever. Dengue fever can also be considered as one of the differential diagnosis for the acute gingival bleeding.

    We report the case of a 17-year-old male admitted to our academic hospital with massive rectal bleeding. Since childhood he had reported recurrent gastrointestinal bleeding and had two exploratory laparotomies 5 and 2 years previously. An emergency abdominal computed tomography scan, gastroscopy and colonoscopy, performed after hemodynamic stabilization, were considered normal. High-dose intravenous proton pump inhibitor (PPI) therapy was initiated and bleeding stopped spontaneously. Two other massive rectal bleeds occurred 8 h after each cessation of PPI which led to a hemostatic laparotomy after negative gastroscopy and small bowel capsule endoscopy. This showed long tubular duplication of the right colon, with fresh blood in the duplicated colon. Obscure lower gastrointestinal bleeding is a difficult medical situation and potentially life-threatening. The presence of ulcerated ectopic gastric mucosa in the colonic duplication explains the partial efficacy of PPI therapy. Obscure gastrointestinal bleeding responding to empiric anti-acid therapy should probably evoke the diagnosis of bleeding ectopic gastric mucosa such as Meckel's diverticulum or gastrointestinal duplication, and gastroenterologists should be aware of this potential medical situation.

    2005-01-01

    Full Text Available Upper gastro-intestinal bleeding remains a cornerstone in surgical practice and unfortunately its’ management is profoundly variable according to hospital protocols and local standards of care. Medical interventions are acting at different levels of medical care and a range of specialist are involved in the process, starting from family practitioners to surgeons, as well as highly trained specialist in interventional endoscopy or radiology. This review is trying to establish the landmarks in the early assessment and care of patients with upper gastro-intestinal bleeding, irrespective of the morphological cause of the bleeding. We propose a protocol for the management both of portal and non-portal upper-gastrointestinal bleedings, prior to endoscopic diagnosis. It is fundamental to establish a standard of care which is feasible in Romania and can work both in university and district hospitals. The protocol is marking the essential gestures with their relevance for the bleeding patient but also reminds the significance of clinical evaluation and safety in transportation of the patient to the nearest emergency room. A battery of simple test should be performed in every patient and data interpreted with care, as results vary according to the level of haemodynamic compensation. Standard empiric therapy for upper gastro-intestinal bleeding is not yet been established but a couple of alternatives emerge as possible solutions. We discuss the benefits of a standard therapy based on H2 blockers, proton pump inhibitors, octreoctide and somatostatin regarding both portal and non-portal bleedings.

  17. Selective serotonin reuptake inhibitors and the risk of bleeding

    2013-06-01

    Full Text Available Background: Selective serotonin reuptake inhibitors (SSRIs are commonly prescribed agents for various conditions in general psychiatry. There is a strong consensus that blockade of serotonin reuptake affects primary hemostasis, namely platelet activity, thus resulting in a bleeding tendency. Considering that SSRIs are commonly prescribed, this study was conducted to assess if they were associated with an increased risk of bleeding. Methods: This was a prospective, open-label study of 30 patients attending the Psychiatry out-patient department, Dr. B. R. Ambedkar Medical College, Bangalore who satisfied DSM-IV criteria for a primary diagnosis of depression, treated with SSRIs. Bleeding time, clotting time, prothrombin time, partial thromboplastin time and platelet count were assessed at baseline and at the end of 6 weeks of treatment or occurrence of bleeding symptom. Results: The patients aged between 18-55 years of whom 21 were females, were treated with an SSRI (fluoxetine 12, escitalopram 12 and sertraline 6 patients. Six patients had overt symptoms of bleeding (upper gastrointestinal bleeding (hematemesis 4; epistaxis 2 and petechiae 2 of whom one patient gave a history of both hematemesis and petechiae and another of hematemesis and epistaxis. The average day after treatment beginning, on which patients reported with bleeding was 30.33 (26-40 days. There was a significant increase in the bleeding time (p=0.028 and clotting time (p=0.042, implying derangement in platelet aggregation. There was no significant change in the other parameters. Conclusion: Treatment with SSRIs increases the risk of bleeding. However, large, randomized controlled trials are required to re-affirm these findings.

    Owing to advances in video-assisted thoracic surgery (VATS), the majority of pulmonary resections can currently be performed by VATS in a safe manner with a low level of morbidity and mortality. The majority of the complications that occur during VATS can be minimized with correct preoperative planning of the case as well as careful pulmonary dissection. Coordination of the whole surgical team is essential when confronting an emergency such as major bleeding. This is particularly important during the VATS learning curve, where the occurrence of intraoperative complications, particularly significant bleeding, usually ends in a conversion to open surgery. However, conversion should not be considered as a failure of the VATS approach, but as a resource to maintain the patient's safety. The correct assessment of any bleeding is of paramount importance during major thoracoscopic procedures. Inadequate management of the source of bleeding may result in major vessel injury and massive bleeding. If bleeding occurs, a sponge stick should be readily available to apply pressure immediately to control the haemorrhage. It is always important to remain calm and not to panic. With the bleeding temporarily controlled, a decision must be made promptly as to whether a thoracotomy is needed or if the bleeding can be solved through the VATS approach. This will depend primarily on the surgeon's experience. The operative vision provided with high-definition cameras, specially designed or adapted instruments and the new sealants are factors that facilitate the surgeon's control. After experience has been acquired with conventional or uniportal VATS, the rate of complications diminishes and the majority of bleeding events are controlled without the need for conversion to thoracotomy.

    Selected quality issues pertinent to the determination of accurate results in the haemostasis laboratory are discussed. Specifically, the implementation of a successful external quality-assessment scheme is described, including its impact on result accuracy as well as the programme's unique challenges and opportunities. Errors in the preanalytical phase of laboratory testing represent the greatest source for reporting incorrect test results. Some of the most common preanalytical errors are described including those that necessitate sample rejection. Analytical means to identify potential sources of error and analytical means to overcome particular interferences are described. Representing the most important clinical complication in the treatment of patients with haemophilia, quality issues related to determination of the presence of inhibitory antibodies against factor VIII (FVIII) are reviewed. Heat treatment of patient plasma prior to testing, particularly in patients receiving replacement FVIII concentrate or during induction of immune tolerance to achieve more accurate results is recommended, while screening activated partial thromboplastin time-based mixing tests to rule out inhibitor presence is discouraged. The initiatives presented in this review can be implemented in robust and resource restricted settings to improve the quality of laboratory testing in patients with bleeding disorders. PMID:27405682

    AIM:TO determine the expression of HER2 and bradykinin B1 receptors (B1R) in the two pathogenic models of gallbladder cancer:the metaplasia-dysplasia-carcinoma and the adenoma-carcinoma pathways.METHODS:Receptor proteins were visualized by immunohistochemistry on 5-μm sections of paraffin-embedded tissue.Expression of both receptors was studied in biopsy samples from 92 patients (6 males and 86 females; age ranging from 28 to 86 years,mean 56 years).High HER2 expression in specimens was additionally investigated by fluorescence in situ hybridization.Cell proliferation in each sample was assessed by using the Ki-67 proliferation marker.RESULTS:HER2 receptor protein was absent in adenomas and in normal gallbladder epithelium.On the contrary,there was intense staining for HER2 on the basolateral membrane of epithelial cells of intestinal metaplasia (22/24; 91.7%) and carcinoma in situ (9/10;90%),the lesions that displayed a significantly high proliferation index.Protein up-regulation of HER2 in the epithelium with metaplasia or carcinoma in situ was not accompanied by HER2 gene amplification.A similar result was observed in invasive carcinomas (0/12).The B1R distribution pattern mirrored that of HER2 except that B1R was additionally observed in the adenomas.The B1R appeared either as cytoplasmic dots or labelingon the apical cell membrane of the cells composing the epithelia with intestinal metaplasia (24/24; 100%) and carcinoma in situ (10/10; 100%) and in the epithelial cells of adenomas.In contrast,both HER2 (4/12; 33%)and B1R (1/12; 8.3%) showed a low expression in invasive gallbladder carcinomas.CONCLUSION:The up-regulation of HER2 and B1R in precursor lesions of gallbladder carcinoma suggests cross-talk between these two receptors that may be of importance in the modulation of cell proliferation in gallbladder carcinogenesis.

    Primary splenic angiosarcoma is a very rare,aggressive neoplasm with a high metastatic rate and dismal prognosis. This neoplasm usually presents with abdominal pain, splenomegaly, anemia, and thrombocytopenia. Splenic angiosarcoma with bleeding gastrointestinal metastases is extremely rare. The literature contains only two case reports. This study reported a 44-year-old male patient with splenic angiosarcoma with sustained repeated gastrointestinal bleeding due to small bowel metastases. Salvage surgery was performed by splenectomy and resection of the metastatic small bowel tumors. The post-operative course was uneventful; the patient survived with the disease and had no GI bleeding, 7 mo after surgery.

  5. Interventional angiography in the diagnosis of acute lower gastrointestinal bleeding

    International Nuclear Information System (INIS)

    Interventional angiography with the use of indwelling arterial catheters, anticoagulants, vasodilators and fibrinolytic agents, complements conventional angiography in the diagnosis of acute lower gastrointestinal bleeding. These interventional techniques prolong, augment or reactive bleeding and, by enabling better timing of examinations, they increase the diagnostic efficacy of angiography. In the reported series of 63 patients with acute lower gastrointestinal hemorrhage, interventions increased the diagnostic yield of angiography for demonstration of extravasation from 32% to 65% and decreased the percentage of negative angiograms from 27% to 16%. Indications, techniques and risks of interventional angiography in the diagnosis of acute lower gastrointestinal bleeding are discussed. (orig.)

    Mesenteric varices can appear as massive, acute lower gastrointestinal bleeding. The small bowel or colon may be involved, varices usually developing at sites of previous surgery or inflammation in patients with portal hypertension. Two patients with alcoholic cirrhosis and protal hypertension presented with rectal bleeding. Tc-99m RBC studies demonstrated varices and extravasation into the adjacent bowel. The varices were documented by mesenteric angiography. Characteristic features of Tc-99m labeled RBC studies can identify mesenteric varices as the cause of intestinal bleeding and localize the abnormal vessels.

    International Nuclear Information System (INIS)

    Four test programs of Bleed Condenser pressure relief valves (RVs) have been completed. This work was initiated following two events in which Bleed Condenser REs were damaged. During one event, the piping connecting one of the RV's to the Bleed Condenser also failed. The author describes the investigations of these events and subsequent testing of several different RV designs. Based on the test results, pressure relief valve designs suitable for this service have been determined. Lessons learned are applicable to pressure relief valves in liquid services

    2007-03-01

    Deep hypothermic circulatory arrest (DHCA) is a technique of extracorporeal circulation commonly used in children with complex congenital heart defects undergoing surgical repairs. The use of profound cooling (20 degrees C) and complete cessation of circulation allow adequate exposure and correction of these complex lesions, with enhanced cerebral protection. However, the profound physiologic state of DHCA results in significant derangement of the coagulation system and a high incidence of postoperative bleeding. This review examines the impact of DHCA on bleeding and transfusion requirements in children and the pathophysiology of DHCA-induced platelet dysfunction. It also focuses on possible pharmacologic interventions to decrease bleeding following DHCA in children. PMID:17484172

  9. Embolization of Bleeding Stomal Varices by Direct Percutaneous Approach

    International Nuclear Information System (INIS)

    Stomal varices can occur in patients with stoma in the presence of portal hypertension. Suture ligation, sclerotherapy, angiographic embolization, stoma revision, beta blockade, portosystemic shunt, and liver transplantation have been described as therapeutic options for bleeding stomal varices. We report the case of a 21-year-old patient with primary sclerosing cholangitis and colectomy with ileostomy for ulcerative colitis, where stomal variceal bleeding was successfully treated by direct percutaneous embolization. We consider percutaneous embolization to be an effective way of treating acute stomal bleeding in decompensated patients while awaiting decisions regarding shunt procedures or liver transplantation.

  10. Fluidised bed heat exchangers

    International Nuclear Information System (INIS)

    Problems that have arisen during the initial stages of development of fluidised bed boilers in which heat transfer surfaces are immersed in fluidised solids are discussed. The very high heat transfer coefficients that are obtained under these conditions can be exploited to reduce the total heat transfer surface to a fraction of that in normal boilers. However, with the high heat flux levels involved, tube stressing becomes more important and it is advantageous to use smaller diameter tubes. One of the initial problems was that the pumping power absorbed by the fluidised bed appeared to be high. The relative influence of the fluidising velocity (and the corresponding bed area), tube diameter, tube spacing, heat transfer coefficient and bed temperature on pumping power and overall cost was determined. This showed the importance of close tube packing and research was undertaken to see if this would adversely affect the heat transfer coefficient. Pressure operation also reduces the pumping power. Fouling and corrosion tests in beds burning coal suggest that higher temperatures could be reached reliably and cost studies show that, provided the better refractory metals are used, the cost of achieving higher temperatures is not unduly high. It now remains to demonstrate at large scale that the proposed systems are viable and that the methods incorporated to overcome start up and part lead running problems are satisfactory. The promising role of these heat transfer techniques in other applications is briefly discussed

    For nearly 60 years, since it was introduced by Graham and Cole (1924), oral cholecystography (OCG) has been used as the imaging technique of choice in investigation of gallbladder disorders. Recently, the future of OCG has come into doubt, principally as a result of ultrasonography, with the advent of high-resolution real-time scanning. Stones are seen as echoes within the lumen of the gallbladder and are associated with an acoustic shadow, findings which are highly specific. On this basis, to evaluate the accuracy of ultrasonography in detecting cholelithiasis, the A. have performed by real-time cholecystosonography 60 patients with not diagnostic OCG in a group of 546 patients affected by gallbladder diseases. Our results have confirmed that sonography revealed 4 normal gallbladders, 51 gallstones and 1 primary gallbladder cancer, with 5 cases of false positive. The true false negative rate has been difficult to determine, as surgery is usually not performed after a negative study. The accuracy of cholecystosonography for gallstone diagnosis was found to be 88,1% for all three Crade's categories. PMID:6866302

  12. Radionuclide-monitoring of gastro-intestinal bleeding-activity

    International Nuclear Information System (INIS)

    Radionuclide-monitoring was done in 50 patients to assess gastro-intestinal bleeding, activity and location. Monitoring with 99mTc-in vivo-labelled erythrocytes was performed as sequential scintigraphy in increments of 1-2 hours up to 62 hours. 23 patients without active GI-bleeding were correctly identified. 27 patients showed pathologic activities in abdominal bloodpool-scintigraphy. In 25 patients peristaltic movement of these activities were seen - in each case we correctly diagnosed active GI-bleeding. In 2 patients the activity stayed for a longer period in the same location - one patient had a liverhemangioma, the other patient had an aneurysma of the arteria mesenterica superior. The great impact of radionuclide-monitoring on diagnostic and therapeutic management of gastrointestinal bleeding is emphasized. (orig.)

    2014-03-01

    Full Text Available Despite the success of therapeutic treatment of peptic ulcer and the introduction of endoscopic technologies, the problem of peptic ulcer hemorrhage remains valid. A large number of publications in foreign literature are dedicated to epidemiology and prevention of bleeding, evaluation of modern tactics and search for new methods of treatment. The works relating to organization of aid to patients with peptic ulcer bleeding are of particular interest. According to the recent data not all clinics even in economically developed countries manage to follow the recommendations of an international consensus-2010 for non-variceal bleeding treatment of upper gastrointestinal tract. Among the causes of non-compliance of international recommendations there are subjective and objective factors, the understanding of which can significantly affect the optimization of aid to patients with peptic ulcer bleeding.

    2016-04-01

    Gastrointestinal bleeding remains a major cause of mortality in patients with cirrhosis. The most common source of bleeding is from gastroesophageal varices but non-variceal bleeding from peptic ulcer disease also carries a significant risk in patients with liver disease. The prognosis is related to the severity of the underlying liver disease, and deaths often occur due to liver failure, infection or renal failure. Optimal management should therefore not only achieve haemostasis but address these complications as well. The management of gastrointestinal bleeding in patients with cirrhosis includes a range of medical, endoscopic and radiological interventions. This article updates the recent developments in this area and highlights topics where further research is still required. PMID:26581713

    A system and method for correcting a large fuel cell voltage spread for a split sub-stack fuel cell system. The system includes a hydrogen source that provides hydrogen to each split sub-stack and bleed valves for bleeding the anode side of the sub-stacks. The system also includes a voltage measuring device for measuring the voltage of each cell in the split sub-stacks. The system provides two levels for correcting a large stack voltage spread problem. The first level includes sending fresh hydrogen to the weak sub-stack well before a normal reactive bleed would occur, and the second level includes sending fresh hydrogen to the weak sub-stack and opening the bleed valve of the other sub-stack when the cell voltage spread is close to stack failure.

    Full Text Available Samples of active coke, fresh and spent after cleaning flue gases from communal waste incinerators, were investigated. The outer layers of both coke particles were separately removed by comminution in a spouted bed. The samples of both active cokes were analysed by means of densities, mercury porosimetry, and adsorption technique. Remaining cores were examined to determine the degree of consumption of coke by the sorption of hazardous emissions (SO2, HCl, and heavy metals through its bed. Differences in contamination levels within the porous structure of the particles were estimated. The study demonstrated the effectiveness of commercial active coke in the cleaning of flue gases.

  11. 18F-FDG PET/CT in the evaluation of gallbladder carcinoma - Initial experience

    International Nuclear Information System (INIS)

    Background: Gallbladder carcinoma, beside gastric and breast cancer, is one of the leading cause of death for cancer in Chilean women reaching a mortality rate of 12.9 per 100.000 women. The global prognosis remains poor, with global lethality around 95%. The most frequent clinical manifestations are: incidental finding in a biopsy of a laparoscopic cholecystectomy, gallbladder mass with or without jaundice and peritoneal carcinomatosis. Usually the diagnosis is too late, most patients show invasion of nearly organs and lymph nodes involvement. Like in other type of tumors, preoperative staging is essential for an adequate treatment selection. Treatment of early stage or locoregional involvement is surgery and chemo-radiotherapy. In advances stage only palliative chemotherapy or palliative cares are indicated. In local disease, imaging tests are useful for detecting lymph nodes, hilar or hepatic involvement, and to rule out spread metastases. Conventional imaging modalities, such as ultrasonography, CT, and MRI may underestimate disease extension. There are few experience of 18FDG PET-CT and gallbladder carcinoma communicated in the medical literature. Most of these publications are dealing with differential diagnosis of gallbladder tumors for detection of malignancy. In this report we present our initial experience evaluating patients suffering from gallbladder carcinoma with 18FDG PET/CT. The goal of this study was to assess the metabolic activity, localization and extension of gallbladder tumor by PET/CT. Methods: We studied prospectively 17 consecutive patients (2 males and 15 females); mean age 56.6 years (range 33 - 77) with histologically proven gallbladder carcinoma. Eleven patients were studied after cholecystectomy. The remaining were unresectable at the time of diagnosis. Clinical indications for 18FDG PET-CT were: to evaluate surgery chance in 8 patients, chemotherapy response in 2, staging and follow up in 3 and to confirm disseminated disease seen in

    Endoscopic submucosal dissection (ESD) has become widely accepted as a standard method of treatment for superficial gastrointestinal neoplasms because it enables en block resection even for large lesions or fibrotic lesions with minimal invasiveness, and decreases the local recurrence rate. Moreover, specimens resected in an en block fashion enable accurate histological assessment. Taking these factors into consideration, ESD seems to be more advantageous than conventional endoscopic mucosal resection (EMR), but the associated risks of perioperative adverse events are higher than in EMR. Bleeding after ESD is the most frequent among these adverse events. Although post-ESD bleeding can be controlled by endoscopic hemostasis in most cases, it may lead to serious conditions including hemorrhagic shock. Even with preventive methods including administration of acid secretion inhibitors and preventive hemostasis, post-ESD bleeding cannot be completely prevented. In addition high-risk cases for post-ESD bleeding, which include cases with the use of antithrombotic agents or which require large resection, are increasing. Although there have been many reports about associated risk factors and methods of preventing post-ESD bleeding, many issues remain unsolved. Therefore, in this review, we have overviewed risk factors and methods of preventing post-ESD bleeding from previous studies. Endoscopists should have sufficient knowledge of these risk factors and preventive methods when performing ESD.

  14. Transcatheter embolization for treatment of acute lower gastrointestinal bleeding

    International Nuclear Information System (INIS)

    Treatment of lower gastrointestinal bleeding was attempted in 13 patients by selective embolization of branches of the mesenteric arteries with Gelfoam. Bleeding was adequately controlled in 11 patients with active bleeding during the examination. One patient improved after embolization but bleeding recurred within 24 hours and in another patient the catheterization was unsuccessful. Five patients with diverticular hemorrhage were embolized in the right colic artery four times, and once in the middle colic artery. Three patients had embolization of the ileocolic artery because of hemorrhage from cecal angiodysplasia, post appendectomy, and leukemia infiltration. Three patients had the superior hemorrhoidal artery embolized because of bleeding from unspecific proctitis, infiltration of the rectum from a carcinoma of the bladder, and transendoscopic polypectomy. One patient was septic and bled from jejunal ulcers. Ischemic changes with infarction of the large bowel developed in two patients and were treated by partial semi-elective colectomy, three and four days after embolization. Four other patients developed pain and fever after embolization. Transcatheter embolization of branches of mesenteric arteries in an effective way to control acute lower gastrointestinal bleeding, but still has a significant rate of complications that must be seriously weighed against the advantages of operation.

A total of 11 children with congenital portosystemic shunt were included in this study, 7 with extrahepatic portosystemic shunts and 4 with intrahepatic portosystemic shunts. Six patients with gastrointestinal bleeding had an extrahepatic portosystemic shunt, and the imaging results showed that the shunts originated from the splenomesenteric junction (n = 5) or splenic vein (n = 1) and connected to the internal iliac vein. Among the five cases of congenital portosystemic shunt without gastrointestinal bleeding, one case was an extrahepatic portosystemic shunt and the other four were intrahepatic portosystemic shunts. Most congenital portosystemic shunt patients with gastrointestinal bleeding had a shunt that drained portal blood into the iliac vein via an inferior mesenteric vein. This type of shunt was uncommon, but the concomitant rate of gastrointestinal bleeding with this type of shunt was high. (orig.)

    The capacity of oral cholecystography (OCG), real-time ultrasound (RUS), and computed tomography (CT) to detect gallstones and to analyze their size, number, and composition was tested preoperatively in 37 patients undergoing elective cholecystectomy. Gallbladder response to a standard meal was also evaluated by OCG and RUS. Gallstones were analyzed chemically for calcium, cholesterol, and bilirubin content. The results show that RUS is the most valuable test for detecting gallstones and is similar to OCG in measuring their size and number, whereas CT underestimates the stone size. Gallbladder function in terms of contractibility can be evaluated by RUS and OCG, but RUS provides useful information even if the gallbladder is not opacified at OCG. CT is more accurate than OCG in detecting the presence of calcium, and CT attenuation numbers are positively correlated with calcium content of the stone (r = 0.87, p less than 0.01). PMID:1612312

    Increased gallbladder (GB) pressure is probably a part of the pathogenesis of acute cholecystitis, and measurements of GB pressure might therefore be of interest. The aim of this study was to validate a microtip pressure transducer for intraluminal GB pressure measurements. In vitro precision and...... accuracy was within 0.2 mmHg, (SD) and 0.6 +/- 0.1 mmHg (mean +/- SD), respectively. Pressure rise rate was 24.8 +/- 5.5 mmHg s-1. Zero drift was in the range 0.3 +/- 0.4 to 0.8 +/- 0.9 mmHg (mean +/- SD). GB pressure was investigated in 16 patients with acute cholecystitis treated with percutaneous...

  19. Bed expansion crucible tests

    International Nuclear Information System (INIS)

    The Am/Cm program will vitrify the americium and curium currently stored in F-canyon. A batch flowsheet has been developed (with non-radioactive surrogate feed in place of the F-canyon solution) and tested full-scale in the 5-inch Cylindrical Induction Melter (CIM) facility at TNX. During a normal process run, a small bed expansion occurs when oxygen released from reduction of cerium (IV) oxide to cerium (III) oxide is trapped in highly viscous glass. The bed expansion is characterized by a foamy layer of glass that slowly expands as the oxygen is trapped and then dissipates when the viscosity of the foam becomes low enough to allow the oxygen to escape. Severe bed expansions were noted in the 5-inch CIM when re-heating after an interlock during the calcination phase of the heat cycle, escaping the confines of the melter vessel. In order to better understand the cause of the larger than normal bed expansion and to develop mitigating techniques, a series of three crucible tests were conducted

    Experimental study on the maximum spoutable bed height of a spout-fluid bed (cross-section of 0.3 m x 0.03 m and height of 2 m) packed with Geldart group D particles has been carried out. The effects of particle size, spout nozzle size and fluidizing gas flow rate on the maximum spoutable bed height were studied. Experimental data were compared to some published experiments and predictions. The results show that the maximum spoutable bed height of spout-fluid bed decreases with increasing particle size and spout nozzle size, which appears the same trend to that of spouted beds. The increasing of fluidizing gas flow rate leads to a sharply decrease in the maximum spoutable bed height. The existent correlations of the maximum spoutable bed height in the literature were observed to involve large discrepancies. Additionally, the flow characteristics when bed materials deeper than the maximum spoutable height were summarized. Under this condition, the spout-fluid bed operated without a stable and coherent spout or fountain assembles the characteristics of jetting fluidized bed. Besides, the mechanisms of spout termination were investigated. It was found that slugging in the spout and growth of instabilities would cause the spout termination in spout-fluid bed.

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

    International Nuclear Information System (INIS)

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

    The objective of this study was to evaluate the safety and therapeutic efficacy of percutaneous radiofrequency (RF) ablation for the treatment of hepatocellular carcinomas (HCCs) adjacent to the gallbladder with the use of internally cooled electrodes. We retrospectively assessed 45 patients with 46 HCCs (mean size, 2.2 cm) adjacent to the gallbladder ({<=} 1.0 cm) treated with RF ablation using an internally cooled electrode system. An electrode was inserted into the tumor either parallel (n = 38) or perpendicular (n = 8) to the gallbladder wall. The safety and therapeutic efficacy of the procedures were assessed with clinical and imaging follow-up examinations. Follow-up with the use of CT ranged from four to 45 months (mean, 19 months). The association between variables (electrode direction, electrode type, tumor size, tumor location, lobar location) and the presence of a residual tumor or local tumor progression was also analyzed. There were no major complications and minor complications were noted in three patients (7%) including one case of vasovagal syncope and two cases of bilomas. Wall thickening of the gallbladder adjacent to the RF ablation zone was noted in 14 patients (41%) as determined on immediate follow-up CT imaging. Wall thickening showed complete disappearance on subsequent followup CT imaging. The primary technique effectiveness rate was 96% (44/46) based on one-month follow-up CT imaging. Local tumor progression was noted in six (14%) of 44 completely ablated tumors during the follow-up period. The direction of electrode insertion (perpendicular), tumor size ({>=} 3 cm) and tumor location (a tumor that abutted the gallbladder) were associated with an increased risk of early incomplete treatment. No variable was significantly associated with local tumor progression. Percutaneous RF ablation of HCCs adjacent to the gallbladder using an internally cooled electrode is a safe and effective treatment. Significant risk factors that lead to early

  3. Differentiating xanthogranulomatous cholecystitis from wall-thickening type of gallbladder cancer: Added value of diffusion-weighted MRI

    International Nuclear Information System (INIS)

    Aim: To evaluate the benefit of diffusion-weighted imaging (DWI) in differentiating xanthogranulomatous cholecystitis from the wall-thickening type of gallbladder cancer. Materials and methods: This retrospective study was approved by the institutional review board. Fourteen patients with xanthogranulomatous cholecystitis and 19 patients with the wall-thickening type of gallbladder cancer were included. Qualitative (visual diffusion restriction compared to liver parenchyma) and quantitative [apparent diffusion coefficient (ADC)] analyses were performed. Conventional MRI findings including dynamic enhancement pattern between the two groups were also analysed. Two observers independently reviewed conventional magnetic resonance imaging (MRI) images and subsequently reviewed combined conventional MRI and DWI images. Pairwise comparison of the receiver operating characteristic (ROC) curves was used to compare diagnostic performances. Results: In conventional MRI findings, xanthogranulomatous cholecystitis showed significant continuity of enhancing mucosal line [79% (11/14) versus 26% (5/19), p = 0.003] and intramural T2-high signal intensity [64% (9/14) versus 21% (4/19), p = 0.012] compared to the wall-thickening type of gallbladder cancer. The enhancement pattern of gallbladder cancer compared to liver parenchyma showed earlier onset than that of xanthogranulomatous cholecystitis (p = 0.001). Diffusion restriction was more frequently seen in the wall-thickening type of gallbladder cancer (68%, 13/19) than in xanthogranulomatous cholecystitis (7%, 1/14; p −3 mm2/s versus 1.076 × 10−3 mm2/s, p = 0.005). Diagnostic performance [area under ROC curve (Az)] of both observers improved significantly after additional review of DWI; Az improved from 0.737 to 0.930 (p = 0.027) for observer 1 and from 0.675 to 0.938 (p = 0.008) for observer 2. Conclusion: Addition of DWI to conventional MRI improves discrimination between xanthogranulomatous cholecystitis and the wall

    Full Text Available Context Papillary gallbladder adenocarcinoma (PGA represents 5% of malignant gallbladder tumors. Metastatic disease frequently involves lymph nodes or other structures in the hepatoduodenal ligament. Case Report A 59 year old female with right upper quadrant pain and a giant gallbladder on ultrasound was found to have a segment 6 liver lesion during an attempted laparoscopic cholecystectomy. After appropriate staging, she underwent an open cholecystectomy and extended right hepatic lobectomy with portal lymph node dissection. Pathology demonstrated well-to-moderately differentiated PGA with identical morphology and immunohistochemistry in the liver resection specimen with negative margins. Despite adjuvant chemotherapy, she developed increased uptake in the head of the pancreas on PET scan. Endoscopic ultrasound with fine needle aspiration demonstrated metastatic PGA. She underwent an attempted Whipple operation but due to repeatedly positive pancreatic duct margins, she ended up with a total pancreatectomy and splenectomy. Final pathology showed metastatic PGA along the entire length of the pancreatic duct with only a single focus of tumor invasion into thepancreatic parenchyma. She developed a new liver metastases six months later that was unresponsive to FOLFOX therapy and she died of metastatic disease 33 months from her initial diagnosis. Conclusion To our knowledge, this is the first report of metastatic PGA recurring along the entire pancreatic duct with disease confined to the pancreas only. We hypothesize that papillary tumor cells spread to pancreatic duct via the common bile duct and remained dormant for several years. An aggressive surgical approach may prolong survival in wellselected patients with PGA’s.

  5. Relative measurement of heavy elements in the bile gallbladder and gallstone

    International Nuclear Information System (INIS)

    Particle Induced X-Ray Emission is a suitable method for the analysis of biological samples in which heavy trace elements are contained in light matrix elements. It is very important to know which factors or probably elements act as initial seed and lead to growing the sands. The goal of this study was to compare the relative values of Fe/K, Cu/K and Zn/K for gallstones, gallbladder, and bile of a specific patient for studying the origination of forming the gallstones. Materials and Methods Human gallbladder, bile, and gallstone samples were obtained by surgical operation from 15 patients and are bombarded by 2.0 MeV energy proton beams produced by van de Graaff accelerator in vacuum. All .. the gallstones were chosen of pigment type of stones and, all the patients were adults. In contrast with conventional methods, the shell and center of the sands has been analyzed separately. The PIXE spectrum analysis was performed using the nonlinear least square fitting code AXIL and GUPIX. Results: The results of detected minor and trace elements shows that the precipitation of calcium salt in the bile lead to reduction of crystals' formation. Elemental comparison of pigment type of gallstone and bile shows that the concentration of calcium in the shell of the stones is four times more than that in the bile. Conclusion: Precipitation of the calcium from the saturated bile on the cholesterols as a seed of gallstones led to reduced sands formation. Analysis of the gallbladder of the same patients revealed no relation between elemental concentrations of bile and gallstones

    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

    Pattinson, N R; Willis, K E

    1990-12-01

    A phospholipase C in bile, free of bacterial infection, has recently been identified from cholesterol gallstone patients. Because of the importance of phosphatidylcholine in solubilizing cholesterol in bile, this study further investigates the metabolism of phosphatidylcholine in delipidated gallbladder and common bile duct biles. Phospholipase C activity, as measured by the release of phosphoryl[3H]choline from the substrate 1,2-dipalmitoyl-sn-glycero-3-phospho [N-methyl-3H]choline, was identified in both hepatic and gallbladder biles. Similar levels of activity (nmol.h-1.mg-1 of delipidated protein) were found in common bile duct (11.25 +/- 14.23) and gallbladder bile (19.07 +/- 22.24), although per milliliter of bile, the mean gallbaldder levels were 6.4 times greater than those found in common duct bile. With the tow substrates, 1-palmitoyl-2[9,10-3H] palmitoyl-sn-glycero-3-phosphocholine and 1,2(1-14C) dipalmitoyl-sn-glycero-3-phosphocholine, the majority of organically extracted label, after thin-layer chromatography, was recovered as radiolabeled diglyceride, confirming the presence of phospholipase C. Diglyceride levels were found to be closely correlated with [3H]choline (slope, 0.9820; r = 0.9844). In addition to diglyceride, both radiolabeled free fatty acid and monoglyceride were identified in common bile duct and gallbladder biles, although their levels were an order of magnitude less than measurable phospholipase C activity. To determine whether the free fatty acid release was due to either a diacylglycerol-lipase or a phospholipase A2, the effect of adding unlabeled diglyceride on free fatty acid formation from the substrate [14C]DPPC was examined. As the concentration of unlabeled diglyceride was increased, the amount of free fatty acid and monoglyceride released were both reduced in parallel. Direct measurement of diacylglycerol-lipase activity by incubating the diglyceride, sn-2[3H]dipalmitoyl, resulted in release of both products in a ratio

  13. Oridonin induces apoptosis and cell cycle arrest of gallbladder cancer cells via the mitochondrial pathway

    International Nuclear Information System (INIS)

    Gallbladder cancer is the most frequent malignancy of the bile duct with high aggressive and extremely poor prognosis. The main objective of the paper was to investigate the inhibitory effects of oridonin, a diterpenoid isolated from Rabdosia rubescens, on gallbladder cancer both in vitro and in vivo and to explore the mechanisms underlying oridonin-induced apoptosis and cell cycle arrest. The anti-tumor activity of oridonin on SGC996 and NOZ cells was assessed by the MTT and colony forming assays. Cell cycle changes were detected by flow cytometric analysis. Apoptosis was detected by annexin V/PI double-staining and Hoechst 33342 staining assays. Loss of mitochondrial membrane potential was observed by Rhodamine 123 staining. The in vivo efficacy of oridonin was evaluated using a NOZ xenograft model in athymic nude mice. The expression of cell cycle- and apoptosis-related proteins in vitro and in vivo was analyzed by western blot analysis. Activation of caspases (caspase-3, -8 and -9) was measured by caspases activity assay. Oridonin induced potent growth inhibition, S-phase arrest, apoptosis, and colony-forming inhibition in SGC996 and NOZ cells in a dose-dependent manner. Intraperitoneal injection of oridonin (5, 10, or 15 mg/kg) for 3 weeks significantly inhibited the growth of NOZ xenografts in athymic nude mice. We demonstrated that oridonin regulated cell cycle-related proteins in response to S-phase arrest by western blot analysis. In contrast, we observed inhibition of NF-κB nuclear translocation and an increase Bax/Bcl-2 ratio accompanied by activated caspase-3, caspase-9 and PARP-1 cleavage after treatment with oridonin, which indicate that the mitochondrial pathway is involved in oridonin-mediated apoptosis. Oridonin possesses potent anti-gallbladder cancer activities that correlate with regulation of the mitochondrial pathway, which is critical for apoptosis and S-phase arrest. Therefore, oridonin has potential as a novel anti-tumor therapy for the

    AIM: To compare clinical presentation and ultrasound (US) and computed tomography (CT) sensitivity between intraluminal and infiltrating gallbladder carcinoma (GBCA).METHODS: This retrospective study evaluated 65 cases of GBCA that were categorized morphologically into the intraluminal-GBCA ( n = 37) and infiltrating-GBCA ( n = 28) groups. The clinical and laboratory findings, presence of gallstones, gallbladder size, T-staging, nodal status, sensitivity of preoperative US and CT studies,and outcome were compared between the two groups.RESULTS: There were no significant differences between the two groups with respect to female predominance,presence of abdominal pain, serum aminotransferases level, T2-T4 staging, and regional metastatic nodes.Compared with the patients with intraluminal-GBCA, those with infiltrating-GBCA were significantly older (65.49 ± 1.51 years vs 73.07 ± 1.90 years), had a higher frequency of jaundice (3/37 patients vs 13/28 patients) and fever (3/37 patients vs 10/28 patients), higher alkaline phosphatase (119.36 ± 87.80 IU/L vs 220.68 ± 164.84 IU/L) and total bilirubin (1.74 ± 2.87 mg/L vs 3.50 ± 3.51 mg/L) levels, higher frequency of gallstones (12/37 patients vs 22/28 patients), smaller gallbladder size (length, 7.47 ± 1.70 cm vs 6.47 ± 1.83 cm; width, 4.21 ± 1.43 cm vs 2.67 ± 0.93 cm), and greater proportion of patients with < 12 mo survival (16/37 patients vs 18/28 patients). The sensitivity for diagnosing intraluminal- GBCA with and without gallstones was 63.6% and 91.3% by US, and 80% and 100% by CT, respectively.The sensitivity for diagnosing infiltrating-GBCA with and without gallstones was 12.5% and 25% by US, and 71.4% and 75% by CT, respectively.CONCLUSION: In elderly women exhibiting small gallbladder and gallstones on US, especially those with jaundice, fever, high alkaline phosphatase and bilirubin levels, CT may reveal concurrent infiltrating-GBCA.

    In this study, we describe a new semi-quantitative method for measuring the extent of bleeding in pathohistological tissue samples. To test our novel method, we recruited 120 female patients in their first trimester of pregnancy and divided them into three groups of 40. Group I was the control group, in which no dilation was applied. Group II was an experimental group, in which dilation was performed using classical mechanical dilators. Group III was also an experimental group, in which dilation was performed using a hydraulic dilator. Tissue samples were taken from the patients' cervical canals using a Novak's probe via energetic single-step curettage prior to any dilation in Group I and after dilation in Groups II and III. After the tissue samples were prepared, light microscopy was used to obtain microphotographs at 100x magnification. The surfaces affected by bleeding were measured in the microphotographs using the Autodesk AutoCAD 2009 program and its "polylines" function. The lines were used to mark the area around the entire sample (marked A) and to create "polyline" areas around each bleeding area on the sample (marked B). The percentage of the total area affected by bleeding was calculated using the formula: N = Bt x 100 / At where N is the percentage (%) of the tissue sample surface affected by bleeding, At (A total) is the sum of the surfaces of all of the tissue samples and Bt (B total) is the sum of all the surfaces affected by bleeding in all of the tissue samples. This novel semi-quantitative method utilizes the Autodesk AutoCAD 2009 program, which is simple to use and widely available, thereby offering a new, objective and precise approach to estimate the extent of bleeding in tissue samples.

    Full Text Available Abstract Background A bleeding pseudoaneurysm in patients with chronic pancreatitis is a rare and potentially lethal complication. Optimal treatment of bleeding peripancreatic pseudoaneurysm remains controversial. This study reports on experience at Chang Gung Memorial Hospital (CGMH in managing of bleeding pseudoaneurysms associated with chronic pancreatitis. Methods The medical records of 9 patients (8 males and 1 female; age range, 28 – 71 years; median, 36 years with bleeding pseudoaneurysms associated with chronic pancreatitis treated at CGMH between Aug. 1992 and Sep. 2004 were retrospectively reviewed. Alcohol abuse (n = 7;78% was the predominant predisposing factor. Diagnoses of bleeding pseudoaneurysms were based on angiographic (7/7, computed tomographic (4/7, ultrasound (2/5, and surgical (2/2 findings. Whether surgery or angiographic embolization was performed was primarily based on patient clinical condition. Median follow-up was 38 months (range, 4 – 87 months. Results Abdominal computed tomography revealed bleeding pseudoaneurysms in 4 of 7 patients (57%. Angiography determined correct diagnosis in 7 patients (7/7, 100%. The splenic artery was involved in 5 cases, the pancreaticoduodenal artery in 2, the gastroduodenal artery in 1, and the middle colic artery in 1. Initial treatment was emergency (n = 4 or elective (n = 3 surgery in 7 patients and arterial embolization in 2. Rebleeding was detected after initial treatment in 3 patients. Overall, 5 arterial embolizations and 9 surgical interventions were performed; the respective rates of success of these treatments were 20% (1/5 and 89% (8/9. Five patients developed pseudocysts before treatment (n = 3 or following intervention (n = 2. Pseudocyst formation was identified in 2 of the 3 rebleeding patients. Five patients underwent surgical treatment for associated pseudocysts and bleeding did not recur. One patient died from angiography-related complications. Overall mortality
