Sample records for cholecystography

  1. Gonad doses in biliary tract examinations (cholecystography)

    International Nuclear Information System (INIS)

    622 single measurements of gonad doses were performed during cholecystography in patients of either sex (intravaginally in women). In oral cholecystography on an average 13 mR were revealed for men and 149 mR for women, resp. According to a minimum, medium, or maximum extent of examination, in intravenous cholecystography the data for men were 11, 17, and 24 mR, while the corresponding data for women were 93, 185, and 278 mR. Based on about 400,000 cholegraphic examinations per year in the GDR the contribution to the total gonad dose caused by radiological examinations is 6-8%. (author)

    Retrospective and prospective studies were done to evaluate the efficacy of oral cholecystography (OCG) performed before hospital discharge on alcoholic patients with acute pancreatitis. In the retrospective study, OCG adequately opacified the gallbladder in 21 of 26 patients (81%). Of the 5 patients with inadequate opacification, 1 was jaundiced at the time of OCG; the other 4 had OCG before resumption of solid food. In the prospective study, OCG done in nonjaundiced patients shortly after resumption of food yielded adequate opacification in 19 of 21 patients (90%) without gallstones. We conclude that in nonjaundiced alcoholic patients with acute pancreatitis not caused by gallstones, OCG performed after resumption of a solid diet and before hospital discharge is usually successful in opacifying the gallbladder.

    300 non-selected patients with bilious dyspepsia with or without typical colics were examined in order to find out the use of a systematical application of Ceruletid in cholecystography. The patients were intramuscularly admininistered 0.3 ..mu..g Ceruletid per 1 kg of the body weight. X-ray pictures were taken after 5, 10, 20 and 30 minutes, the size of the gall bladder was measured planimetrically. The contraction of more than 25% was regarded as normal. In most cases, the presentation of the ductus cysticus and the choledochus was satisfactory and made an intravenous cholangiography unnecessary. Side effects were rare, they passed and in no case needed therapy. By applying Ceruletid the diagnostical reliability of the cholecystography was increased. Basing on our experiences we can state that Ceruletid is indicated in cholecystography in the following cases: in the case of gallstones to test the gall bladder function and for the presentation of the choledochus; in the case of the so-called 'malformed gallbladder' to exclude hyperplastic cholecystoses in the case of alithiatic gall bladders of patients with gall colics to find hyperplastic cholecystoses and gall-bladder dyskinesia; for patients with cholecystography and gastrointestinal passage.

    Cholecystosonography, cholecystography and CT were true positive in 93.3%, 71.2% and 69.7% of patients with gallstones, respectively. Cholecystosonography was significantly more sensitive than the other two. True negative rates were more than 95% in the three tests. Cholecystography and CT were competitive with sonography in 0.54 and 0.6 of true positives, respectively. Competitive or complementary rate was thought to be an index for an effective combination of tests. Though sonography is most suitable for screening, cholecystography and CT have their own particular diagnostic values on gallstones.

  8. Infusion cholecystography in the diagnosis of acute cholecystitis

    International Nuclear Information System (INIS)

    The use of infusion cholecystography as an aid in the diagnosis of acute cholecystitis was investigated in 21 patients. Seventeen of 18 patients (94%) with positive cholecyst-tomograms who underwent laparotomy had confirmation of acutely inflamed gallbladders both macroscopically and histologically. These findings suggest that infusion cholecystography can make a significant contribution in reducing the incidence of misdiagnosis in acute cholecystitis, and that the investigation should be part of the management of patients in whom early surgery is planned.

  9. 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.)

  13. Results obtained with ultrasound and X-ray cholecystography in the diagnosis of the gall bladder

    International Nuclear Information System (INIS)

    In 205 patients examination of the gall bladder was carried out by cholecystography (per os or iv./) and by gray-scale echography. By comparative evaluations the iv. cholecystography proved to be the most accurate method (97.5%). Per os cholecystography and echocholecystography exhibited similar results (96% and 95.6% resp.). In the cases of acute cholecystitis, pancreatitis and jaundice echography is proposed, whereas in chronic biliary diseases peroral cholecystography is advised as the first radiological examination. If X-ray examination uncovers a non-filling gall bladder, echography may provide direct proof of cholelithiasis. (L.E.)

  14. Sodium taurocholate, ineffective as an adjuvant in oral cholecystography

    International Nuclear Information System (INIS)

    The effect of 6 g sodium taurocholate on the visualization of the gall bladder with calcium iopodate (Solu-Biloptin, Leiras, Schering AG) was studied on 140 patients with a control group of 99 patients. The administration of sodium taurocholate with a contrast medium did not improve the opacification of the gall bladder in oral cholecystography with calcium iopodate but induced a significant increase in side effects.

    In comparing the diagnostic specificity and sensitivity of oral cholecystography with that of sonography in 479 patients in a community hospital, the oral cholecystogram, when used with a double dose of contrast agent, showed greater specificity (1.00) and sensitivity (0.99) than the sonogram (0.54 and 0.94, respectively). Because of lower cost, the oral cholecystogram should be used as the initial diagnostic study when cholelithiasis is suspected, unless specific contraindications exist.

    Differentiating hepatocellular disease versus biliary obstruction can be challenging in dogs presented for icterus. The purpose of this prospective study was to determine the feasibility of percutaneous contrast ultrasound-guided cholecystography in dogs. Ten normal dogs weighing 7.6-13.0 kg (median 9.8 kg) were recruited. All dogs were considered normal based on complete blood count, serum chemistry profile, ultrasound examination, and percutaneous radiographic cholecystography. Percutaneous contrast ultrasound-guided cholecystography was performed using 0.5 ml of commercially available contrast agent and two conventional ultrasound machines for simultaneous scanning at two different locations. Two observers independently evaluated the time to initial detection of contrast in the proximal duodenum and duration of contrast enhancement via visual monitoring. Dynamic contrast enhancement was calculated using time-intensity curves. Mean (± SD) and median (range) of time to initial detection were 8.60 s (± 3.35) and 8.0 s (2.0-11.0), respectively, and mean and median duration were 50.45 s (± 23.24) and 53.0 s (20.0 - 70.0), respectively. Mean, median, and range of peak intensity were 114.1 mean pixel value (MPV) (SD ± 30.7), 109.2 MPV, and 79.7-166.7, respectively, and mean, median, and range of time to peak intensity were 26.1 s (SD ± 7.1 s), 24.0 s, and 19.0-41.0 s, respectively. Findings indicated that percutaneous contrast ultrasound-guided cholecystography is a feasible technique for detecting and quantifying patency of the bile duct in normal dogs. Future studies are needed to assess the diagnostic utility of this technique for dogs with biliary obstruction. PMID:25403172

  18. Combined infusion cholecystography in patients with the postgastroresection syndromes

    International Nuclear Information System (INIS)

    Using a combined infusion cholecystography in patients with postgastroresection syndromes, the concentration, motor-evacuator function of the biliary bladder and changes in biliary tracts are studied. 71 patients (63 men and 8 women) in the age of 31-65 have been investigated. It is shown that in patients who have suffered resection, the interaction of motor-evacuator function of the gastrointestinal tract.and biliary tracts is upset which can further lead to profound pathologic changes in these organs

    Because the efficacy of cholecystokinin cholecystography in the detection of chronic acalculous cholecystitis remains in doubt, the procedure is rarely used in clinical practice. However, the ability to observe gallbladder contraction with sonography and /sup 99m/Tc-para-isopropylacetanilido-iminodiacetic acid cholescintigraphy (PIPIDA) offers a possibility to improve the sensitivity of the test. To determine if the degree of gallbladder contraction after cholecystokinin is the same as measured by the three techniques and if it differs in symptomatic patients compared to the normal population, cholecystokinin cholecystography, cholecystokinin sonography, and cholecystokinin PIPIDA were performed in 10 symptomatic patients and 10 normal volunteers. The mean maximum contraction of the gallbladder during the three studies was 63%, 61%, and 68%, respectively, for the volunteers, and 72%, 63%, and 73%, respectively, for the patients. The mean maximum gallbladder contraction during all three procedures was 64% +/- 26% SD in the volunteers and 74% +/- 17% SD in the patients. The differences were not statistically significant. Although there was good correlation in the degree of maximum gallbladder contraction among cholecystokinin cholecystography, cholecystokinin sonography, and cholecystokinin PIPIDA, marked variation in both the volunteers and the patients makes it unlikely that the degree of contraction as observed by any of these techniques can be used to indicate the presence of chronic acalculous cholecystitis.

    Eighteen percutaneous biliary opacifications form the basis of this report (mean age = 5 years, 5 months). From their study of choledochal cysts (three cases), ductular hypoplasia (two cases), primary sclerosing cholangitis (four cases), choledochal stone (one case), pancreatic lymphoma (one cae), and biliary atresia (seven cases), four conclusions can be drawn: (a) percutaneous cholecystography is a safe and useful procedure, (b) abnormal pancreatico-biliary junction is often demonstrated preoperatively in choledocal cysts, (c) primary sclerosing cholangitis can be recognized by percutaneous opacification, and (d) cholangiography is useful in selecting the surgical and nonsurgical cases in patients with biliary atresia and dysfunctioning hepatoportoenterostomy

  4. Improvement of oral cholecystography and cholangiography with Ceruletid

    International Nuclear Information System (INIS)

    Following oral cholecystography in 100 patients, the conventional 'fatty meal' was replaced by an intramuscular injection of Ceruletid in a dose of 0.4 μg/kg body weight. The synthetic decapetide Ceruletid is a substance with a hormone-like effect on the gastro-intestinal tract. It contracts smooth muscle in the gut and stimulates secretion in the stomach and the exocrine pancreas. Compared with other substances producing contraction which are given orally, Ceruletid acts more quickly and more powerfully in producing contraction of the gall bladder muscle. In 86% of positive cholecystograms, this resulted in satisfactory demonstration of the bile duct, 66% better than for oral substances. Many abnormalities, particularly localised adenomyomatosis, can only be diagnosed after good contraction of the gall bladder. Side effects, such as nausea, dizziness and a feeling of heat were transitory. In three patients it led to vomiting. The rapid and certain effect of Ceruletid during oral cholecystography requires reassessment of the role of intravenous cholangiography in diagnosis. Particularly amongst outpatients, with a high proportion of normal gall bladders, it is possible to complete the examination in one stage by demonstrating the bile duct with Ceruletid. (orig.)

  6. Oral cholecystography: Is the fatty meal always necessary

    International Nuclear Information System (INIS)

    In our study we have collected 1000 consecutive cases of oral cholecystographic opacification of the gall-bladder and common bile duct; occasionally a complimentary intra-venous cholangiography had also been carried out. In 360 cases there was disease of the gall-bladder or a faint opacification of the gall-bladder. In 640 cases, the gall-bladder looked normal and among these cases the common bile duct was abnormal in only three cases, which is a rate of 0,47%. Therefore the fatty meal after oral cholecystography should not be done in each case but only if there is a presumptive diagnosis of pancreatic disease, if there is pancreatic calcification, or if surgery has been previously performed on the biliary tract or duodenum.

    1981-01-01

    Oral cholecystography (OCG) has traditionally been delayed until several weeks after hospitalization for pancreatitis because of the putative frequent poor visualization during the acute episode. Recently, OCG with iopanoic acid was reported successful in most patients with acute pancreatitis soon after resumption of a solid diet. We evaluated OCG with sodium tyropanoate, a pharmacokinetically different contrast material, in 30 hospitalized patients with pancreatitis before resumption of solid food. It accurately evaluated the gallbladder in 24 cases (80%). Abnormal liver function tests, including mild hyperbilirubinemia, did not interfere with the examination. Consequently, 1) tyropanoate OCG adequately opacifies the gallbladder in most patients with acute pancreatitis who are fasting or taking liquids only; 2) allows gallbladder evaluation earlier than with iopanoic acid OCG; 3) is less affected by hepatic dysfunction; and 4) provides an alternative to ultrasonography.

    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.

    Laparoscopic cholecystectomy can be performed safely in most patients with symptomatic cholelithiasis. Preoperative evaluation should assess the potential problems that affect the performance of laparoscopic cholecystectomy. Hepatobiliary scintigraphy or oral cholecystography can assess the gallbladder function and nonvisualization of gallbladder usually indicates acute or severe chronic cholecystitis. The purpose of this study was to evaluate the role of preoperative hepatobiliary scintigraphy or oral cholecystography in predicting the performance of laparoscopic cholecystectomy. The study group consists of 176 patients who underwent both hepatobiliary scintigraphy with Tc-99m DISIDA and oral choelcystography within one month before laparoscopic cholecystectomy. Nonvisualization of gallbladder was defined as persistent nonvisualization of gallbladder until 4 hours on hepatobiliary scintigraphy or 12 hours on oral cholecystography. Among 176 patients, gallbladder was not visualized in 38 patients on hepatobiliary scintigraphy and 41 patients on oral cholecystography. Concordance rate between hepatobiliary scintigraphy and oral cholecystography was 89.2%. The conversion rate to open cholocystectomy was significantly higher in patients with nonvisualization of gallbladder than in patients with gallbladder higher in patients with nonvisualization of gallbladder visualization (15.8% vs 2.9% on hepatobiliary scintigraphy, 12.2% vs 3.7% on oral cholecystography: p<0.01 and p<0.05 respectively). The operative complication rate was also significantly higher in patients with nonvisualization of gallbladder (13.2% vs 2.9% on hepatobiliary scintigraphy, 14.6% vs 2.2% on oral cholecystography : p<0.01 and p<0.001, respectively). Similarly, operation time was significantly prolonged in patients with nonvisualization of gallbladder (88.8{+-}41.9 min vs 62.5{+-}23.6 min on hepatobiliary scintigraphy : p<0.001, 89.4{+-}41.3 min vs 61.8{+-}22.8 min on oral cholecystography :p<0

  11. The role of hepatobiliary scintigraphy and oral cholecystography in predicting the performance of laparoscopic cholecystectomy

    International Nuclear Information System (INIS)

    Laparoscopic cholecystectomy can be performed safely in most patients with symptomatic cholelithiasis. Preoperative evaluation should assess the potential problems that affect the performance of laparoscopic cholecystectomy. Hepatobiliary scintigraphy or oral cholecystography can assess the gallbladder function and nonvisualization of gallbladder usually indicates acute or severe chronic cholecystitis. The purpose of this study was to evaluate the role of preoperative hepatobiliary scintigraphy or oral cholecystography in predicting the performance of laparoscopic cholecystectomy. The study group consists of 176 patients who underwent both hepatobiliary scintigraphy with Tc-99m DISIDA and oral choelcystography within one month before laparoscopic cholecystectomy. Nonvisualization of gallbladder was defined as persistent nonvisualization of gallbladder until 4 hours on hepatobiliary scintigraphy or 12 hours on oral cholecystography. Among 176 patients, gallbladder was not visualized in 38 patients on hepatobiliary scintigraphy and 41 patients on oral cholecystography. Concordance rate between hepatobiliary scintigraphy and oral cholecystography was 89.2%. The conversion rate to open cholocystectomy was significantly higher in patients with nonvisualization of gallbladder than in patients with gallbladder higher in patients with nonvisualization of gallbladder visualization (15.8% vs 2.9% on hepatobiliary scintigraphy, 12.2% vs 3.7% on oral cholecystography: p<0.01 and p<0.05 respectively). The operative complication rate was also significantly higher in patients with nonvisualization of gallbladder (13.2% vs 2.9% on hepatobiliary scintigraphy, 14.6% vs 2.2% on oral cholecystography : p<0.01 and p<0.001, respectively). Similarly, operation time was significantly prolonged in patients with nonvisualization of gallbladder (88.8±41.9 min vs 62.5±23.6 min on hepatobiliary scintigraphy : p<0.001, 89.4±41.3 min vs 61.8±22.8 min on oral cholecystography :p<0.001).

    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.

    In a prospective, blinded study of 109 patients with cholecystolithiasis, oral cholecystography and 99Tcm-EHIDA cholescintigraphy were compared in terms of reliability for demonstrating cystic duct patency: one of the prerequisites for extracorporal shock wave lithotripsy (ESWL) treatment of cholecystolithiasis. Patients with a positive result on one or both tests were regarded as having cystic duct patency. Patients with negative and uncertain result of both tests or one of each were regarded as having no cystic duct patency. Concordance between the two tests was obtained in 93 of 109 patients. The diagnostic reliability of cholescintigraphy and oral cholecystography were 95 and 86%, respectively (P < 0.05), suggesting a more precise determination of gallbladder filling with scintigraphy.

    Real-time ultrasonography is more accurate and technically more efficient than gray scale ultrasonography in establishing the diagnosis of cholecystolithiasis. In prospective studies accuracy may be as high as 96%, and reflects the use of specific sonographic diagnostic criteria. Retrospective studies, however, reveal a lower accuracy rate of 90%, suggesting that practicing radiologists are not ready to accept these restricting criteria. On the other hand, oral cholecystography (OCG) is well tolerated and gives a reproducible, reliable result independent of technical expertise. It is 96% accurate in detecting the presence of gallstones and carries a sensitivity of .97. Both studies are prone to overinterpretation, which skews specificity and adversely affects diagnostic accuracy. In this retrospective review of 234 consecutive cases of cholecystectomy, real-time ultrasound was 90% accurate with a sensitivity of .96 in determining the presence of cholecystolithiasis. Oral cholecystography was 95% accurate with a sensitivity of .97. PMID:3303363

    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.

    Since its introduction in 1924, oral cholecystography has been used as a screening method in the diagnosis of the gallbladder disease. Recently, intravenous cholangiography has become a most valuable method in the diagnosis of biliary tract pathology because of its advantage of simultaneous visualization of the gallbladder and bile ducts in a short time. However, opinions vary considerably as to the significance of nonvisualization of the gallbladder with oral cholecystography. In attempt to evaluate how much intravenous cholangiography does contribute to the diagnosis in the cases that the gallbladder cannot be opacified or can only faintly visualized by the oral method, we have made a clinical observation in 168 patients, in whom intravenous cholangiography had been performed within a week following oral cholecystography, at Korea General Hospital during the last three years from January 1969 to December 1971. The results obtained are summarized as follows; 1. The results of oral cholecystography in 168 cases were as follow; well opacification of the gallbladder in 10 cases, faint opacification in 46 cases and nonopacification in 112 cases. 2. In 37.5% (42 cases) of 112 gallbladder not opacified by the oral method, the gallbladder was subsequently opacified by the intravenous method, and 11.6% (14 cases) turned out to be normal when examined by the intravenous method. 3. Further demonstration of abnormalities could be obtained with the aid intravenous cholangiography in 28 cases (16.6%); cholelithiasis in 12 cases and choledocholithiasis in 16 cases. 4. In every cases of 14 patients whose gallbladder were virtually not opacified by both oral and intravenous methods bit the common bile ducts could be opacified by intravenous cholangiography, definite abnormalities were identified in the gallbladder at surgery.

    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...

    Oral cholecystography after ingestion of the 3.0 gr. Sodium tyropanoate (Bilopque ) was done in 504 patients from January 1983 to August 1983. Simple supine views of the abdomen of 37 patients, in whom the gallbladder was either nonvisualized or faintly visualized upto 17 hours after Bilopaque administration, were reviewed in search of the presence of conjugated material in the bowel. The results were as follows: 1. The ratio of male to female was nearly 2 : 3 and age distribution was even from 20 years to 79 years. 2. Among 26 cases which showed conjugated Bilopaque in the bowel, cholecystitis with stone was 20 cases (77%) and acalculus cholecystitis was 6 cases (23%). 3. Among 11 case which showed no conjugated Bilopaque in the bowel, hepatitis was 3 caes (28%) and clonorchis sinensis, salmonellosis, pancreatitis, acute gastritis was 2 cases (13%) respectively. 4. All of the 20 cases of cholecystitis with stone showed conjugated Bilopaque in the bowel. 5. Among 6 cases of which conjugated Bilopaque in the bowel, salmonellosis was 1 case (17%) and remaining 5 caes (83%) were acalculus cholecystitis. 6. The result of our study show that the presence of conjugated Bilpaque in the bowel in nonvisualized or faintly visualized gallbladder after oral cholecystography is of definite indicative of cholescystitis. 7. Surgical intervention or ultrasonographic examination of the gallbladder without double dose or second dose oral cholecystography on such cases is recommended.

    Full Text Available Introduction Standard diagnostic procedures (anamnesis, physical examination, laboratory analyses, ultrasound diagnosis, commonly used in diagnosis and preparation for surgical intervention of patients with cholelithiasis, are in most cases a reliable indicator for evaluation of the disease and conditions planned for surgery. Discussion In some cases by application of these narrow diagnostic models, some conditions, anatomic variations and biliary tract malformations remain unrecognized. Asymptomatic ('silent' choledocholithiasis (2.02% represents a special diagnostic and therapeutic problem. Conclusion Our extended diagnostic protocol includes routine intravenous cholangio-cholecystography as a standard diagnostic procedure for evaluation of cholecysto-choledocholithiasis prior planning cholecystectomy.

    Oral cholecystography has been proved useful and widely used as screening method in the gallbladder disease. The material consisted of 1,005 cases including 411 males and 591 females of oral cholecystography performed at Soonchunhyang College Hospital during the last two years from 1977 to 1979. The authors analyzed relationship of gallbladder shape to cholelithiasis and biliary dyskinesia. The results obtained are as follows: 1. Among 1,005 cases, 414 cases were male and 591 cases were female. The female was predominant than the male and highly affected between 41-50 years of age. 2. Shape of the gallbladder was classified into the 9 types; most popular type was pear type.3. Incidence of gallbladder was more common in septated and folding type than others. 4. Male to female ratio of gallstone was 54 :84 of total 138 cases, and peak age was 41 to 60 years (65.2%). 5. In 138 gallstone cases, opaque stones were 65 cases (47.1%) and nonopaque stone were 73 cases (52.9%). 6. The emptying rate of gallbladder was faster in the male than female, and faster in the older are group over 51 years than the younger age group below 30 years. Average emptying rate was 41.8%.7. Biliary dyskinesia was predominant between the age of 31-40 (37.3%). We classified the biliary dyskinesia into 3 type; hyperkinetic dyskinesia, hypotonic dyskinesia and hypertonic dyskinesia. Most prevalent type was hypotonic dyskinesia,24 cases (47.1%).

    Assessment of the size and number of gallstones is important in the external shock wave lithotripsy. The authors retrospectively analyzed 69 sonograms and 25 oral cholecystograms in terms of size and member of gallstones and compared with gallstones removed at surgery. The size and number of gallstones were correctly diagnosed in 41%(28/69) by sonography and 54%(7/13) by oral cholecystography. When stones were multiple, the assessment of the size and number were difficult, sonogram being correct in 11%(2/18)and oral cholecystogram being correct in 66%(2/3). On the basis of our results, painstaking examination is necessary in the evaluation of gallstones in patients undergoing external shock wave lithotripsy

    Two randomised groups of 100 subjects each, undergoing oral cholecystography, were given either a 6 g fractionated dose of iopanoic acid (Telepaque) or sodium ipodate (Biloptin) to determine the relative merits of this dose schedule. Exclusions to the study were pregnancy and iodine sensitivity. Calculi or abnormal gall-bladder opacification were present in 45% of subjects. Both agents were equally effective in demonstrating abnormalities, although bile duct visualisation was better using iopanoic acid (P<0.05). Of 46 subjects with abnormal cholecystograms subsequently undergoing surgery, all had the diagnosis confirmed. Side effects occurred in 63% of all subjects, being twice as common in those taking iopanoic acid (P<0.01). Sodium ipodate in a large fractionated dose is favoured because of the lower occurrence of side effects without loss of diagnostic accuracy.

    1984-01-28

    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

    Ultrasound and oral cholecystography (OCG) are both used to evaluate candidates for biliary lithotripsy. Some investigators have suggested abandoning the OCG, believing that sufficient screening information can be obtained from ultrasound. This study compares ultrasound and OCG in assessing the size and number of gallstones, both in vitro and in vivo. In the in vitro model, 35 gallstones, divided into 20 groups, were separately suspended in dilute contrast media in a phantom, and examined by ultrasound and simulated OCG by each of three gastrointestinal radiologists. In the in vivo study, the ultrasound and OCG examinations from 53 patients were independently reviewed by three radiologists. The number and size of the stones were recorded in both studies. In the in vitro study, the stone size was measured within 2 mm of the actual size by OCG in 23/35 stones (66%) and by ultrasound in 4/35 stones (11%). The correct number of stones was determined by OCG in 19/20 groups (95%), and by ultrasound in 14/20 (70%). In the in vivo study, all readers saw the same number of stones in 40/50 (80%) patients by OCG and 33/49 (67%) patients by ultrasound. Statistical analyses revealed correlation coefficients for OCG greater than those for ultrasound in each comparison. The size of the largest stone was within 2 mm by all readers in 26/51 (51%) of patients by OCG and 20/47 (43%) patients by ultrasound. Oral cholecystography is more reliable than ultrasound for the determination of size and number of stones in patients being screened for biliary lithotripsy. PMID:1885268

  14. Concentration and excretion of contrast agents during oral cholecystography as measured by computed tomography in dogs

    International Nuclear Information System (INIS)

    Nine healthy mongrel dogs were given 2 consecutive doses of 1 of 3 cholecystographic contrast agents (iopanoic acid, sodium ipodate, and sodium tyropanoate), followed by daily computed tomograms (CT) and abdominal radiographs in a randomized crossover study in order to determine: (a) the maximum time for excretion of the contrast material from the gallbladder, (b) the maximum time for elimination of contrast material from the blood, and (c) the correlation between the density of the gallbladder on CT and the actual concentration of iodine in the gallbladder bile. In all 9 animals gallbladder opacification disappeared on CT within 4 days after administration of the contrast material. Plain abdominal radiographs did not show gallbladder opacification after 2 1/2 days. Daily blood iodine measurements showed that all of the contrast material was cleared from the blood within 7 days after administration. In 7 dogs CT imaging of the gallbladder was followed by percutaneous aspiration of bile from the gallbladder using CT guidance. There was a direct linear correlation between the actual concentration of iodine in the bile and the density of the gallbladder on CT (r = 0.925). This suggests that CT measurements can be used to determine the concentration of contrast agents in the gallbladder during oral cholecystography. (orig.)

    Nine healthy mongrel dogs were given 2 consecutive doses of 1 of 3 cholecystographic contrast agents (iopanoic acid, sodium ipodate, and sodium tyropanoate), followed by daily computed tomograms (CT) and abdominal radiographs in a randomized crossover study in order to determine: (a) the maximum time for excretion of the contrast material from the gallbladder, (b) the maximum time for elimination of contrast material from the blood, and (c) the correlation between the density of the gallbladder on CT and the actual concentration of iodine in the gallbladder bile. In all 9 animals gallbladder opacification disappeared on CT within 4 days after administration of the contrast material. Plain abdominal radiographs did not show gallbladder opacification after 2 1/2 days. Daily blood iodine measurements showed that all of the contrast material was cleared from the blood within 7 days after administration. In 7 dogs CT imaging of the gallbladder was followed by percutaneous aspiration of bile from the gallbladder using CT guidance. There was a direct linear correlation between the actual concentration of iodine in the bile and the density of the gallbladder on CT (r = 0.925). This suggests that CT measurements can be used to determine the concentration of contrast agents in the gallbladder during oral cholecystography.

    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.

    Fifteen healthy volunteers underwent a randomized trial of oral cholecystography (OCG) using 5 different combinations of contrast agents given as 2 consecutive doses: Telepaque (iopanoic acid) given with food (TF) or without food (T), Bilopaque (sodium tyropanoate) given without food, and a combination of both agents (TF-B). The density of gallbladder opacification was judged visually on a scale of 1+ to 4+ and quantitatively by a densitometric method. Comparison of gallbladder opacification on the first and second days of the study revealed 52 of 75 (70%) combinations (TF-T, TF-TF,T-T, TF-B, B-B) resulted in improved opacification, 17% in equal opacification, and 13% in worse opacification on day 2. The TF-B combination showed the highest number (9) of excellent (grade 4+) results and the lowest number (2) of poor (grade 1+ and 2+) results, gave the best opacification in 8 volunteers, and had the highest average density difference (0.32) between first- and second-day opacifications. The TF-TF combination was the next most effective, and the T-T combination was the least effective. The results indicate that OCG in 2 consecutive doses is superior to single-dose OCG, and that a combination of TF-B or TF-TF will provide the greatest gallbladder opacification. The TF-B combination is recommended because of better patient tolerance. PMID:7045975

    A 75-year-old woman was admitted to our hospital with a gallbladder tumor by detected ultrasonography (US). On endoscopic ultrasonography (EUS), and abdominal CT, we diagnosed the Is+IIa+IIb-like ss lesion invasive gallbladder cancer, but endoscopic double contrast cholecystography suggested IIa+IIb-like ss invasive gallbladder cancer because the lesion had the same granular membrane a other cancer membrane and cholecystectomy was carried out. The pathologic diagnosis was IIa+IIb-like ss invasive gallbladder cancer. PMID:19420873

    Both ultrasonography (US) and oral cholecystography (OCG) are being used to evaluate patients after extracorporeal shock wave lithotripsy (ESWL) for gallstones. Criteria for retreatment after the initial ESWL are usually related to the size of the residual fragments. This study examines the efficacy of ultrasound and OCG for determining both the size and number of stone fragments in the gallbladder in an in vitro model and in patients. Ultrasonography and OCG examinations using an in vitro ESWL phantom with ten groups of stones, and on 39 patients, were reviewed independently by three radiologists to determine both the size and number of stone fragments. For the in vitro study, the three readers estimated the correct number of fragments, or the next closest range, in 87% of observations by OCG and in 43% by US. The size of the largest fragment was measured within 1 mm of its actual size in 87% of observations by OCG and 20% by US. Correlation coefficients for the mean measurements of the three readers versus the actual fragment size and number were greater for OCG than for US. For the in vivo study, the three readers agreed in 47% of the OCG versus 32% of US examinations with respect to the number of fragments, and in 65% of OCG compared to 40% of US studies with respect to size of the largest fragment. Multiple statistical analyses demonstrate that these differences are statistically significant. A discrepancy among the readers concerning whether a patient was eligible for retreatment occurred in 15% of OCG as compared to 45% of US studies. Both the in vivo and in vitro studies indicate that there is more interobserver reproducibility for OCG than for US, and that OCG is more reliable in making the decision concerning patient eligibility for retreatment following lithotripsy.

    1985-01-01

    As part of the British Gallstone Study Group's multi-centre post-dissolution trial of different treatment regimes designed to prevent recurrence after complete gallstone dissolution, the frequency of concordance and discordance between oral cholecystography (OCG) and ultrasonography (U/S), and between repeat U/S studies, in diagnosing recurrent stones was recorded. Before entering the trial, all patients had had complete gallstone dissolution, confirmed by 2 normal OCGs 3 months apart during continued bile acid treatment; and all but three had also had at least 1 normal U/S examination of the gallbladder. During 6-24 months follow-up, from a total of 129 U/S examinations, gallstone recurrence was detected on 25 occasions (19 definite and 6 probable) in 14 patients, and from a total of 71 OCGs, recurrent stones were detected on 11 occasions in 10 patients. All the presumed recurrences developed in the absence of symptoms. On 67 occasions, the OCG and U/S studies were performed within 8 weeks of each other and of these, there was discordance in 15 (22%). On 11 occasions (6 patients), ultrasound suggested recurrent stones despite a normal OCG whilst on 4 occasions (4 patients) stones diagnosed on OCG were not confirmed by ultrasound. Of the 25 instances of U/S recurrence, a further U/S examination was performed on 17 occasions in 11 patients which failed to confirm the initial findings on 8 occasions (7 patients). After 1 year's follow-up, the predicted recurrence rates (pooled data from all 3 treatment groups), as calculated by life table analysis, were 29.3 +/- 7.1%, when the diagnosis was based on 1 U/S; 15.4 +/- 5.8% on 1 OCG; 14.9 +/- 5.6% on 2 successive U/S studies, and 8.1 +/- 4.5% on 1 U/S plus 1 OCG. At 24 months, the corresponding values were 37.2 +/- 8.3, 31.5 +/- 8.6, 18.3 +/- 6.3, and 22.4 +/- 8.6%. These results show that following complete gallstone dissolution by bile acid treatment, there is both intra- and inter-technique variation in the detection

  3. Optimization of the procedure of cholecystography per os in children as a method of raising its diagnostic informative value

    International Nuclear Information System (INIS)

    Methods of performance of unified cholecystograhy per os were developed on the basis of the results of X-ray and ultrasonic investigations of the gall bladder in 168 children. A method of contrast medium dosage to raise the informative value of cholecystography was proposed. A procedure of taking pictures with a patient lying in a prone position, an X-ray tube being turned in accordance with an angle of gall bladder inclination to the anterior abdominal wall, was worked out, making it possible to detect, with a high degree of reliability, the most common development defects of the gall bladder and to define its true sizes on the basis of X-ray findings

  4. Subjective vs. objective evaluation of gallbladder opacification during oral cholecystography in comparative clinical trials: implications for studies involving visual assessment

    International Nuclear Information System (INIS)

    Radiographs and CT images taken during oral cholecystography in dogs were interpreted in an independent, blind fashion by three radiologists on two occasions and visual assessment of gallbladder density compared to the actual CT values. While there was significant intra- and inter-observer variation, the mean scores for the observers' interpretations of both radiographs and prints correlated well with the actual CT values (p > 0.05). In five out of six comparisons between first and second readings, the observers gave a lower score on the second reading. The considerable variation reflects the problems inherent in subjective evaluation of agents that produce small but measurable differences in radiographic density. Studies involving such subjective data have to be carefully designed in order to obtain meaningful results

    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

  7. Prospective study on the value of sonographic and radiographic cholecystography in the diagnosis of gall bladder diseases

    International Nuclear Information System (INIS)

    In this prospective investigation of 281 patients who were examined sonographically and radiographically, the accuracy of the ultrasound diagnosis was 88,9%. The accuracy of the radiographic examinations was 88.6%. In 2.8% of the cases the radiographic findings were wrong. In 5.0% of the cases the radiographic choleocystography did not permit a definite diagnosis. 3.6% of the unambiguous radiographic findings could not be cleared up. The high degree of precision of the ultrasound examination, the total absence of any health hazards and the relatively short time required for the examination indicate the application of sonographic cholecystography as first examination in the diagnosis of gall bladder diseases.

    A prospective study of 116 patients admitted as emergencies with a clinical diagnosis of acute cholecystitis or biliary colic showed that the best investigation for confirming a diagnosis of acute cholecystitis was sup(99m)Tc-pyridoxylidene1 glutamate (PG) scanning. Its sensitivity was 99% and its specificity 86%, whereas those of oral cholecystography were 75% and 82% respectively, and those of ultrasonography were 54% and 62%, respectively. However, estimation of plasma liver enzymes was essential to exclude acute hepatitis before proceeding to early cholecystectomy. (author)

    Prior to non-surgical therapy of gallstones it is important to assess their number and size. In order to evaluate the accuracy of ultrasound (US) and oral cholecystography (OCG) in counting and measuring gallstones, a prospective blind study was conducted to compare the results of US (n = 99) and OCG (n = 36), either alone or in combination (n = 34), with the number and size of gallstones retrieved after cholecystectomy. The number of gallstones was accurately estimated by US and OCG in 74% and 69% of the cases, respectively. In assessing the presence of up to three, five or 10 gallstones both US and OCG proved reliable. In measuring the size of gallstones, there was 19% accuracy with US compared with only 3% with OCG. With an accepted measurement error of 3 mm these values increased to 80% for US and 44% for OCG. US proved more reliable than OCG in discriminating gallstones smaller or larger than 10 mm and smaller or larger than 20 mm, but with US, detection of gallstones larger than 30 mm was problematic. Both US and OCG underestimated gallstone size. The combination of both techniques did not significantly improve the assessment of either number or size of gallstones compared with the results obtained with US or OCG alone. It is concluded that (1) both US and OCG have some limitations in assessing the number and size of gallstones, (2) the combination of both examinations does not improve accuracy, and (3) patient selection for non-surgical treatment of gallstones can be started by US alone.

    2x magnification employing a 200-μ focal spot and an Alpha 8-XM screen/film system was applied to oral cholecystography and the results compared with those for the conventional contact technique with the Par-RP system. The basic imaging properties of the system, as well as phantom studies, indicated that the image quality obtained with magnification is comparable to or better than that for the conventional technique. In clinical studies on the detection of gallstones, the conventional technique revealed 5 true-positive and 17 true-negative cases and 1 false-positive and 2 false-negative cases, while the magnification technique provided 7 true-positive and 18 true-negative cases but no false cases. With the magnification technique the skin dose was reduced to approximately half that for the conventional contact technique

    A prospective study of the accuracy of real time ultrasonography in the detection of gallstones was undertaken in 180 patients from February 1987 to February 1988. The ultrasound findings were compared with single dose oral cholecystography (OCG), and with the surgical findings where surgery was undertaken. Ultrasonography gave more accurate results than OCG, with an overall accuracy in the surgically proven patients of 97.1%, no false positive findings and a 2.9% false negative rate. OCG gave an accuracy of 80% with no false positive findings and a 20% false negative rate. Ultrasound was particularly valuable where there was non visualisation of the gall bladder at OCG, giving an overall accuracy of 93.3% in such patients. Ultrasonography is a non invasive, simple, safe and economic diagnostic test of high accuracy in the diagnosis of cholelithiasis and of particular benefit in those patients unsuited for OCG.

    Cholescintigraphy experience with Tc99m-HIDA and BIDA in 210 patients with gallbladder disease treated at the Soroka Medical Center between the years 1977 - 1979 is described. In this work the utility of the method in both acute and chronic cholecystitis and hepatobiliary disease in the presence of jaundice up to 26 mg% of Bilirubin is demosntrated. Four patients were diagnosed as suffering from Atresia of biliary duct. The most common findings in our series are: all normal gallbladders exhibited filling; absence of visualization indicated gallbladder disease and/or cystic duct obstruction; visualization of the gallbladder after a fatty meal-induced emptying excluded an obstructed cystic duct and acute cholecystitis; a definite diagnosis of hepato-cellular disease, partial and complete obstruction, is possible in jaundiced patients with hyperbilirubinemia. No diagnostic failures due to too low concentration of the tracer in the biliary tract, were observed. Radiation exposure is somewhat greater than in cholecystography and cholangiography. Cholescintigraphy is a suitable complementary or alternative investigation to intravenous cholangiography, especially when poor excretion of the contrast medium or adverse reaction impair the result of the latter. In some of our cases this method proved to be the first choice non invasive procedure, especially in cases with high serum bilirubin up to 26 mg%. (B.G.)

In 32 of them conventional X-ray biligraphy was performed as well. The sensitivity of ultrasonography in patients with cholelithiasis was 97 per cent, the specificity 92,6 per cent and the accuracy 95,7 per cent. The respective percentages for the X-ray examination were 66,7 and 76,5 per cent. The advantage of ultrasonography in patients, in whom the gallbladder escaped visualization on conventional X-ray examination is demonstrated. The economic and health effect, achieved by using ultrasonography is discussed. Ultrasonography is recommended as first diagnostic method for patients with diseases of the bile ducts. Its use as independent tool of diagnosis is also discussed.

This is the second case in Macedonia (population 2.3 million) showing the same pattern of bile dynamic with mebrofenin-Tc-99m: normal HEF, prolonged 'washout'. In Rotor's disease and Dubin-Johnson's syndrome HEF is depressed and 'washout' delayed, whereas in Gilbert's syndrome we found both parameters normal. In our patient the episodes of pruritus were intensive and prolonged, hyperbilirubinaemia 50-100 micromol/L. Gallbladder was hypovolemic, ejection fraction reduced (59%, normal with the employed method over 70%). Growth, body weight and bone age were subnormal. Technetium-sulfur-colloid scans showed enlarged liver, splenomegaly and reduced portal contribution to hepatic blood flow (65%, normal over 70%). (Author)

    Oral cholecystography repeated at six-months intervals is the standard method for determining reduction in size of gall stones (partial success) and complete dissolution of stones (complete success). In a comparative study of oral cholecystography and cholecystosonography six out of 14 patients with gall stones achieving complete success by oral cholecystographic criteria had stones still detectable by ultrasonography. Repeat oral cholecystography in a further 11 patients receiving post-disso...

All patients had cholecystosonography performed ''blindly'' the day prior to the operation (76 had a cholecystectomy and six had a vagotomy). Based upon the operative findings, the diagnostic value of ultrasonic examination for gallstones can be calculated to predictive value of positive test - 1.00; predictive value of negative test - 0.71. The diagnostic failures are discussed but it is not possible to predict which patients will benefit more from peroral cholecystography rather than from ultrasound. It is concluded that cholecystosonography is a safe alternative to peroral cholecystography. (orig.)

    1982-10-01

    Today patients with gallstones are treated surgically, by means of drugs, or by endoscopy. However, only cholesterol stones can be dissolved with bile acids. Besides the cholesterol stones in the gallbladder, insoluble pigment stones or insoluble stones with a high inorganic calcium content will be found. In every patient, the solubility of the gallbladder stones must be established by mineralogical analysis. Sonography is very helpful in detecting gallbladder stones, but it is impossible to perform a mineralogical analysis with this method. Plain radiography is likewise insufficient. The only way to obtain a relatively accurate selection of patients with soluble gallstones is the performance of roentgenography after cholecystography. Cholecystography for mineralogical analysis must always follow detection of gallstones by sonography.

    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.

    Twelve patients and a foetus with congenital bile duct cysts suggested in the majority of cases at routine upper abdominal sonography were examined by two or more of the following investigations: Ultrasonography (10 patients), computed tomography (5 patients), CT-cholangiography (2 patients), oral cholecystography (7 patients), intravenous cholangiography (4 patients), endoscopic retrograde cholangiopancreatography (ERCP) (6 patients) and cholescintigraphy (2 patients). The sensitivity of each investigation for the diagnosis of bile duct cysts was: Ultrasound 40%, computed tomography 20%, CT-cholangiography 100%, oral cholecystography 17%, intravenous cholangiography 75%, ERCP 83% and cholescintigraphy 50%. When a bile duct cyst has been suggested by ultrasonography or other examinations, without a conclusive diagnosis being made, CT-cholangiography is recommended as the next examination. In patients with impaired biliary excretion of contrast medium, ERCP may be required to achieve the diagnosis.

    X-ray radiography of the chest and abdomen can be of use when gall-stones or cholecystitis are suspected, but it is not always necessary. An ultrasonographic examination can also be very useful. If no gall-stones can be found, a cholecystogram must be done. Cholecystography also plays an important part in the tracing of gall-stones. The diagnosis of cholecystitis is best done by means of scintiscanning.

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

    2008-04-01

    Adenomyomatosis is a relatively common abnormality of the gall bladder, with a reported incidence of between 2.8 and 5%. Although mainly confined to the adult study group, a number of cases have been reported in the paediatric study group. It is characterized pathologically by excessive proliferation of the surface epithelium and hypertrophy of the muscularis propria of the gall bladder wall, with invagination of the mucosa into the thickened muscularis forming the so-called 'Rokitansky-Aschoff' sinuses. The condition is usually asymptomatic and is often diagnosed as an incidental finding on abdominal imaging. The radiological diagnosis is largely dependent on the visualization of the characteristic Rokitansky-Aschoff sinuses. As the condition is usually asymptomatic, the importance of making a correct diagnosis is to prevent misinterpretation of other gall bladder conditions such as gall bladder cancer, leading to incorrect treatment. In the past, oral cholecystography was the main imaging method used to make this diagnosis. In most institutions, oral cholecystography is no longer carried out, and the diagnosis is now more commonly seen on cross-sectional imaging. In this review article, we describe the manifestations of adenomyomatosis on the various imaging methods, with an emphasis on more modern techniques such as magnetic resonance cholangiopancreatography. A brief section on oral cholecystography to aid readers familiar with this technique in understanding the comparable imaging features on more modern imaging techniques is included. PMID:18373800

    International Nuclear Information System (INIS)

    Objective: To discuss the therapeutic strategy and the clinical efficacy of percutaneous cholecystostomy in treating high-risk patients with acute cholecystitis. Methods: During the period of Jan. 2006-June 2008, percutaneous cholecystostomy was performed in 27 high-risk patients with acute cholecystitis, consisting of lithic cholecystitis (n = 21) and non-lithic cholecystitis (n = 6). Of 27 patients, percutaneous cholecystostomy via transhepatic approach was performed in 22 and via transperitoneal approach in 5. The 7 F drainage catheter was used. Cholecystography was conducted before the drainage catheter was extracted. Results: Percutaneous cholecystostomy was successfully accomplished in all 27 cases, with a technical success rate of 100%. Postoperative patency of gallbladder drainage was obtained in 25 patients, with the relieving or subsiding of abdominal pain and the restoring of temperature and leukocyte account to normal range within 72 hours. In one patient, as the abdominal pain relief was not obvious 72 hours after the procedure, cholecystography was employed and it revealed the obstruction of the drainage catheter. After reopening of the drainage catheter, the abdominal pain was relieved. In another case, cholecystography was carried out because the abdominal pain became worse after the procedure, and minor bile leak was demonstrated. After powerful anti-infective and symptomatic medication, the abdominal pain was alleviated. The drainage catheter was extracted in 25 patients 6-7 weeks after the treatment. Of these 25 patients, 12 accepted selective cholecystectomy, 7 received percutaneous cholecystolithotomy and 6 with non-lithic cholecystitis did not get any additional surgery. The remaining two patients were living with long-term retention of the indwelling drainage-catheter. Conclusion: Percutaneous cholecystostomy is a simple, safe and effective treatment for acute cholecystitis in high-risk patients. This technique is of great value in clinical

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

The results of oral cholecystography, intravenous cholangiography and ultrasonography were considerably less reliable. One-half of the patients had gangrenous cholecystitis. Cholecystectomy was the preferred operation with an over-all mortality of 9 per cent. IDA cholescintigraphy is an important new modality for the diagnosis of acute acalculous cholecystitis which, in the past, has often been difficult to diagnose.

    Technetium-99m P.G. cholescintigraphy was performed in 27 human volunteers and 81 patients referred for hepatobiliary tract disease. The gallbladder, biliary system, and gastrointestinal tract were well visualized in the normal patients and volunteers. The gallbladder was not visualized in 22 patients with histologically proved cholecystitis with cystic duct obstruction. Nine patients with complete extrahepatic obstruction of the common bile duct were correctly diagnosed. Hepatocellular disease and incomplete obstruction, with and without jaundice, were diagnosed with this technique. Oral cholecystography is superior to this method for the detection of cholelithiasis in nonjaundiced patients.

    In the diagnosis of acute cholecystitis, the interpretation of cholescintigraphy is usually not difficult. It is conceivable, however, that wth unusual location of obstructing calculi atypical images could result. Three cases were studied with cholescintigraphy and one with cholecystography in which more distal locations of obstructing calculi resulted in partial visualization of the gallbladder and erroneous interpretations were possible. Nuclear medicine radiologists should, therefore, be aware that atypical gallbladder images may be the result of unexpected location of obstructing calculi. Clues for assisting in interpretation are offered.

    Twelve patients (11 girls and 1 boy) with dilated bile ducts and anomalous junction between the common bile duct and pancreatic duct are reported. All patients underwent preoperative opacification of the bile ducts either by transhepatic cholangiography or percutaneous cholecystography. Abdominal pain and jaundice were the main clinical symptoms. Reflux of pancreatic enzymes in the bile duct was proven by measuring amylase and lipase activity in the biliary system after IV injection of 1 IU/kg of cholecystokinin. All patients were operated upon. Bile duct size returned to normal in all patients who are clinical well with a follow-up from 6 to 1 years.

    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

    The accuracy, sensitivity, and specificity of ultrasound versus oral cholecystography (OCG) in the preoperative diagnosis of gallstones was studied in 144 patients undergoing cholecystectomy. The 89 per cent accuracy of ultrasound was similar to the 92 per cent achieved with OCG. However, ultrasound was found to have a lower false-positive rate and a greater sensitivity with far fewer indeterminate studies than OCG. A high rate of nonvisualization diminished the usefulness of OCG as a first-line test. Because of a greater sensitivity less tendency for false-positive results, and a moninvasive nature, ultrasound should be the initial diagnostic study of choice in patients with suspected gallstones.

  3. Studies on the influence on the excretory kinetics of 125I-Adipiodon

    International Nuclear Information System (INIS)

    The possibility of influencing distribution and elimination of 125I-Adipiodon (125I-iodipamide meglumine) by a preceding administration of Falignost (iomeglamic acid) as well as by dose-time variants of the mechanic intravenous application of contrast medium was tested in 55 anicteric and 2 icteric patients within clinically indicated cholegraphic examination with the aim of methodical optimization. For the detection of principal regularities comparative studies with 125I-Adipiodon and Falignost in rats as well as examinations of protein binding of 125I-Adipiodon in the plasm of rats and in the plasm and in mixed serum (application in vitro) of patients by gel filtration with Epidex B 2 coarse and batch operation on more than 1,200 samples were additionally carried out. For combined cholecystography with intravenous infusion of Adipiodon in immediate temporal connection with the administration of Falignost a reduced visibility of the biliary tract in the X-ray picture is not to be expected as the consequence of the mutual influence of the contrast media. For intact excretory function of liver and kidneys the combined cholecystography can be recommended. The effects of a dose increase, of protracted infusion of Adipiodon and of the intravenous administration of 0.01 g metroclopramide on the demonstration of the biliary tract in the intravenous cholegram are outlined.

  4. Ultrasound in the detection of focal and segmental hyperplastic cholecystoses

    International Nuclear Information System (INIS)

    The authors describe the sonographic (US) patterns of hyperplastic cholecystoses observed from January 1983 to April 1987 - 39 cases of focal extention and 12 of segmental extension - and confirm the higher sensibility of US versus oral cholecystography. Sonography (SG) allows a straight visualization of the gallbladder wall and its lesions, both in case of limited thickening of the wall (focal cholecystosis) and in case of more extensive thickening (segmental cholecystosis). To cholecystographic findings of focal lesions, SG gives additional information, adding a fundamental diagnostic element: the lack of acoustic shadowing distal to the nodular masses. Nonetheless, SG dose not allow a discrimination between focal cholesterolosis and adenomyomatosis, except for particular cases, such as multiple nodular masses, and coexistence with parietal deposit of cholesterol. Furthermore, the differential diagnosis of focal cholecystoses includes some neoplasms of the gallbladder, and gallstones stuck to the wall, with no acoustic shadowing. In segmental cholecystoses, the direct evaluation of the entity and extension of the wall thickening remains a fundamental diagnostic element, even though such a morphologic detail is often integrated by the functional relieve of hypercontractility of the gallbladder wall after a fatty meal (both oral cholecystography and SG demonstrate it)

  5. Role of cholecystokinetic agents in 99mTc-IDA cholescintigraphy

    1981-07-01

    Cholecystokinin (CCK) and its C-terminal octapeptide analog, Sincalide, have been utilized in two separate roles for the evaluation of gallbladder disease. These are: (1) prior to cholescintigraphy to evacuate the gallbladder and optimized subsequent filling with radiotracers, and (2) to study contractile function of visualizing gallbladders on cholecystography and cholescintigraphy. As a preparation for 99mTc-IDA studies, it clearly facilitates earlier gallbladder filling in patients with chronic cholecystitis, thereby ruling out complete cystic duct obstruction. The problem lies in the fact that the use of CCK as a premedication markedly decreases the sensitivity of the study to detect chronic cholecystitis, since the findings become indistinguishable from patients with normal gallbladders. For this reason, the authors prefer to obtain delayed images, since chronic cholecystitis is frequently associated with gallbladder filling beyond the first hour. The role of CCK in detecting abnormal gallbladder function in the normally visualizing gallbladder also is controversial. Other studies as well as the author's experience suggests that as much as one-forth of positive cases may be associated with normal gallbladders at surgery and often even on microscopic examination. However, most importantly, the great majority of these patients are relieved of their symptoms following surgery. It appears reasonable that CCK or Sincalide cholecystography or cholescintigraphy may be detecting functional abnormalities before anatomic changes occur and can, therefore, serve as a useful examination in selecting symptomatic patients who may benefit from cholecystectomy.

    The Dubin-Johnson syndrome is a hereditary deficiency in the excretion ofconjugated bilirrubin by hepatocytes characterized by chronic hyperbilirubinemia, alteration in coproporphyrin metabolism, and intracellular deposition of a dark melanin-like pigment giving the liver a typical black cast. We report a 28-year-old male patient who presented conjunctival jaundice and conjugated-hyperbilirubinemia without no other alteration in hepatic biochemistry. The diagnosis of this syndrome was perfomed by using the low-risk methods of laparoscopy-facilitated hepatic biopsy and oral cholecystography In contrast, we avoided the classical Bromsulphalein test because of potential severe side effects. We stress here the current importance of these tests for confirming the diagnosis. By using this methodology, we were not able to quantify the isomeric profile of the urinary coproporphyrins nor 99mTc-HIDA cholescintigraphy. In conclusion, we confirm the utility of hepatic biopsy with the aid of laparoscopy and oral cholecystography for the diagnosis of the Dubin-Johnson syndrome on the basis of their effectiveness and relative lack of complications.

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

    International Nuclear Information System (INIS)

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

    1992-07-01

    A prospective blinded comparison of ultrasonography (US) and oral cholecystography (OCG) was performed in 100 patients with symptomatic gall-stones to determine whether US would enable an accurate assessment of cystic duct patency to be made. Patency of the cystic duct was defined as gall-bladder opacification on OCG or a greater than 20% decrease in gall-bladder volume by US post-fatty meal. The ellipsoid method of volume measurement was used. Any patient who had a non-opacified gall-bladder on OCG but a greater than 20% volume decrease on US had cholescintigraphy performed (DISIDA). Oral cholecystography demonstrated cystic duct patency in 88 patients (88%), and fatty-meal gall-bladder US met the specified study criteria for patency in 86 patients (86%). False negative results were identified in four of the OCG and in six of the US examinations. The results of this study indicate that gall-bladder sonography with a post-fatty meal contraction of greater than 20% is a very accurate predictor of cystic duct patency. A contraction of less than 20%, however, cannot be considered a reliable predictor of cystic duct occlusion. PMID:1643780

    If a radiologist from 1950 could travel in time to 2011, he or she would be baffled to see how few of the radiological examinations he was familiar with, remain. We review the radiological examinations that have disappeared since X-rays were discovered, and include the causes of their disappearance. Barium studies have mainly been replaced by endoscopy, oral cholecystography by ultrasound, and intravenous urography by CT-scan. Angiography by means of a direct puncture of carotid artery and aorta has been replaced by Seldinger angiography. Pneumencephalography and myelography have been replaced by CT and MRI. Bronchography has been replaced by bronchoscopy and CT-scan, arthrography by MRI and arthroscopy. Many other radiological examinations have been replaced by ultrasound, CT or MRI. PMID:21447222

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

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

    A great share of hepatic and bile cyst diseases among gastrointestinal diseases necessitates attempts to collect the most complete information on the state of the above organs while using an optimum complex of examination methods. The authors present the results of a multimodality study of 98 patients including i.v. cholecystography and computerized hepatobiliscintigraphy with sup(99m)Tc-HIDA. A detailed analysis of coincidences and divergences in diagnosis is provided. A conclusion has been made as to the great informative value of the x-ray methods for detection of organic defects of the biliary ducts and the advantages of radionuclide study in the evaluation of functional disorders in the liver and biliary tract.

    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

    1982-05-01

    The justification of conventional X-ray diagnostic of bile ducts is repeatedly questioned by newer examination techniques like sonography and ERC. The indication for oral cholecystography is derived from its high-specifity of its statements for gall bladder diagnostic, that is as high as with sonography and does not depend on the experience of the investigator. The importance of the void exposure is undoubted with correspondence of medicamentary litholysis for calcite identification. Furthermore, Choleocystic kineticals like Ceruletid let recognize better hyper plastic choleocysts like adenomyomatoses. The intravenous choleocyst-cholangiography posesses a clearly limited indication scheme even after introduction of sonography and ERC. The infusion method yields a better compatibility of the contrast medium with a simultaneous increased representation quality of the bile duct, that can be increased by a consequent application of the layer exposure technique.

    Rao, B.K.; Lieberman, L.M.

    1980-06-01

    A number of /sup 99m/Tc-labeled pharmaceuticals have been introduced recently for evaluation and diagnosis of hepatobiliary disease. Pyridoxylidene glutamate (PG) and iminodiacetic acid derivatives have evolved as the most useful agents due to excellent biliary excretion with rapid visualization of the gallbladder and the biliary ducts. These radiopharmaceuticals offer substantial advantages over /sup 131/I-rose bengal. In our experience of over 80 patients evaluated for various hepatobiliary disorders with /sup 99m/Tc PG or paraisopropyl acetanilidoiminodiacetic acid (PIPIDA), two patients had early cholescintigrams suggestive of intraluminal defects. These were not confirmed on delayed imaging. The cholescintigrams in these two patients were similar and suggested bile layering. Although demonstration of this phenomenon by oral cholecystography and intravenous cholangiography has been reported, we found no description of bile layering with radiopharmaceuticals.

    Data on clinical and X-ray examination of 29 patients aged 2 weeks to 66 years with vena cava inferior hepatic segment deficiency are presented. The blood outflow from the lower part of the body was effected through the azygos vein in 17 patients, and through the hemiazygos one in 12 patients. The data obtained were in all cases correlated with the results of intracardiac research methods (the right and left heart cavities catherization and angiocardiography), with intraoperative and autopsy findings. An anomaly was found to prevail in patients (89.6%) with different types of abnormal heart position in the thoracic cavity. Along with examination of the cardiovascular system, the abdominal organs study was carried out: standard roentgenoscopy and radiography, both aiming to detect the liver position, gastrointestinal tract examination, and cholecystography.

    1981-08-01

    A prospective study of thyroid function after the administration of iodine-containing radiographic contrast media was carried out on 119 patients from an area where goitres are endemic. Eighteen patients had a negative TRH test after 28 days. Results showed hyperthyroid function in 27.9% of patients after oral cholecystography, 15.1% of patients after intravenous cholangiography and 5.3% of patients after infusion urography. In these patients, thyroxin and triiodothyronin levels were higher than in euthyroid patients. Thyroid stimulating antibodies could not be demonstrated. Induction of hyperthyroidism by iodine is considered to be due to autonomy of the thyroid gland parenchyma. For this reason the risk of iodine-induced hyperthyroidism is greater in patients from a goitre endemic region (by a factor of 1.3 to 17.1).

    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.

    The records of 242 patients, operated consecutively for biliary lithiasis, were analyzed to determine the reliability of oral cholecystography (OCG), ultrasonography (US), and HIDA in detecting biliary calculi. Preoperative interpretations were correlated to operative findings. OCG obtained in 138 patients was accurate in 92%. US obtained in 150 was correct in 89%. The accuracy of HIDA was 92% in acute and 78% in chronic cholecystitis. Intraoperative cholangiography (IOC) done in 173 patients indicated the need for exploratory choledochotomy in 24; 21 had choledocholithiasis. These observations suggest that OCG and US are very accurate, but not infallible, in detecting cholelithiasis. US should be done first; when doubt persists, the addition of OCG allows the preoperative diagnosis of gallstones in 97% of the cases. HIDA is highly accurate but not infallible in detecting acute calculous cholecystitis. IOC is very reliable in detecting choledocholithiasis; thus, its routine is justifiable. PMID:3888131

    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

    Adenomyomatosis (AD) is a degenerative disorder of the gall bladder wall which can be complicated by chronic inflammation and calculi. The true incidence of this disorder in South East Asians is not known. Nine Chinese patients with AD were discovered amongst 200 consecutive right upper quadrant ultrasound examinations. Four of them had cholecystectomy and were diagnosed as cholecystitis by the pathologist. Adenomyomatosis can be suspected on ultrasonography, but should be confirmed by oral cholecystography (OCG). There is great disparity in the ultrasound, OCG, surgical and histopathological diagnosis of this condition. This may be due to the fact that only complicated cases of AD come to surgery, where the presence of chronic cholecystitis or calculi detracts from recognising or overshadows the presence of AD. It is not known whether uncomplicated AD has any clinical significance and whether it, if given sufficient time, will lead to inflammation of the gall bladder. PMID:2203297

  5. Reliability of pre- and intraoperative tests for biliary lithiasis

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

    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

    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.

    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.

    We describe a simple and inexpensive method of monitoring methyl tert-butyl ether (MTBE) dissolution of cholesterol gallstones with thin-layer chromatography (TLC) in 10 patients. TLC is a routine semiquantitative laboratory method that can be used to measure the cholesterol concentration present in the MTBE and bile mixture aspirated through the cholecystostomy catheter during gallstone dissolution. TLC is practical in the clinical setting because it can be used to determine if gallstone dissolution is occurring and when MTBE lavage is no longer effective. TLC is performed in the laboratory with routine material and is completed in 15 min. Each TLC measurement costs about $1. The procedure provides objective and specific chemical information on effectiveness and progression of gallstone dissolution, apart from the radiologic and sonographic studies. In our study, TLC signaled effective dissolution in the initial phase of gallstone dissolution by detecting large amounts of cholesterol in the MTBE and bile mixture even before a visible change in size or shape of the stone became apparent by transcatheter cholecystography or by sonography (six of 10 patients). Conversely, lack of cholesterol on TLC after 1 hr or more of MTBE infusion indicates that the stones are pigmented or contain substantial calcium. This means that dissolution with MTBE will be ineffective and that solvent infusion should be terminated. In those cases in which dissolution is progressing well, when TLC shows decreasing amounts of cholesterol in the effluent, only residual fragments insoluble to MTBE remain or the stone is sequestered from MTBE; at this point, solvent infusion should be discontinued or the catheter must be repositioned. Monitoring the rate of cholesterol dissolution by TLC provides important complementary information to cholecystography and sonography during gallstone treatment with MTBE. PMID:2048533

    Between 1978 and 1985, 11 girls and one boy underwent an elective operation for a congenital choledochal dilatation associated with an anomalous biliopancreatic junction. In 10 out of these 12 cases the children suffered several episodes of abdominal pain, and the diagnosis was missed since a jaundice appeared. The ultrasonographic examination demonstrated in all cases a dilatation of both extra- and intrahepatic bile ducts. The preoperative diagnosis was always established by the mean of a transhepatic cholangiography (8 cases) or a percutaneous cholecystography (4 cases), which showed in every case a dilated choledochus, and a common biliopancreatic channel, 15 to 35 mm long. A high amylase level was found in the bile in 10/10 cases when it was measured. A cholecystokinin test was performed in 4 cases, resulting in each case in a considerable increase of amylase and lipase levels in bile. All children were treated by excision of the dilated choledochus and gallbladder, followed by an hepaticojejunostomy with a Roux en Y loop. The follow-up is 6 months to 5 years for 9 children: 8 are cured, and on girl, who had a major dilatation of the left intrahepatic bile ducts, suffered from episodic abdominal pain and an episode od cholangitis 6 years after the operation. The role of such a common channel in the pathogeny of congenital choledochal cysts, acute pancreatitis in children, and biliary carcinomas in young adults is discussed according to the literatures of the last 10 years.

  14. Gall bladder function test with Ceruletid

    Compared with the stimulating food given orally in the gall bladder function test the administration of the decapeptide Ceruletid which is related with Cholecystokinin has the advantage of avoiding resorption disturbances in the upper gastrointestinal tract. To 100 patients with positive peroral cholecystography, Ceruletid was injected i.m. in a dose of 0.4 ..mu..g/kg body weight. The contrasting of the main bile duct was thus increased from 10% to 86%. The oral stimulating food brings an increase to appr. 20%. A special importance is assigned to the frequent diagnosis of adenomyomatoses which, with 6%, lies significantly above the 0.8% achieved by means of the oral stimulating food. More contractile segments of the gall bladder wall can cause pain symptoms which are typical for the biliary tract. Adenomyomatoses in the region of the infundibulum of the gall bladder cause colicky pains and are, as generally accepted, an absolute indication for a surgical intervention. The finding of small gall bladder concrements is often connected with a strong diminution of the gall bladder in order to prevent the small concrements from being overlapped by the non-contrasting bladder bile. Therefore, the application of Ceruletid should be considered also within the frame of the intravenous cholegraphy, thinking of the large number of normal gall bladder findings which were obtained with the oral stimulating food as the only diagnostical help.

    A comparative test with 80 patients who were either administered Ceruletid i.m. or given stimulating food to make the gall bladder contract for the oral cholecystography revealed that Ceruletid is suitable for contraction of the gall bladder and improves the presentation of the ductus cysticus and the choledochus. During the contraction of the gall bladder, no side effects were observed, even if small or big gallstones had been found. An additional test with 30 patients whose small intestines were examined radiologically showed that Ceruletid, administered intramusucularly, has the effect of considerably reducing the transit time of the barium meal into the ileocoecal region. The average transit time after injecting Ceruletid was 15 minutes which is 80 minutes after physiological salt solution as a placebo. The intramuscular injection of Ceruletid in a dose of 0.3 ..mu..g/kg body weight is a safe and effective method to increase the gall bladder contraction and to shorten the time necessary for transition through the small intestine.

    Ultrasonography, infusion tomography of the gall-bladder and sup(99m)Tc-diethyl acetanilide iminodiacetic acid (DIDA) hepatobiliary scanning were compared in a prospective investigation of 45 consecutive patients in whom acute cholecystitis was suspected clinically. The definitive diagosis of acute cholecystitis was established or excluded at operation in 35 patients, by oral cholecystography in five and by intravenous cholangiography in five. The predictive values of positive and negative results of investigation were 100% and 83%. respectively, with ultrasonography and 98% and 88%, respectively, in hepatobiliary scanning. The corresponding values for infusion tomography were 87% and 33%, respectively. It is concluded from these results that ultrasonography and sup(99m)Tc-DIDA hepatobiliary scanning are capable of establishing the diagnosis rapidly and with certainty in cases of suspected acute cholecystitis. A preliminary account of the results of routine employment of sup(99m)Tc-DIDA hepatobiliary scanning in 29 consecutive patients revealed no erroneous diagnoses. In the majority of patients with acute cholecystitis, operation proved possible within 48 hours of admission.

    Fourteen patients with a cystic duct syndrome (CDS) underwent cholecystokinin (CCK) cholescintigraphy. All patients presented with persistent postprandial right upper quadrant pain and biliary colic. None of the patients had an abnormal oral cholecystography, gallbladder (GB) ultrasound exam or upper GI series. Each patient received 5 mCi of technetium-99m disofenin. When the GB maximally filled, 0.02 microgram/kg CCK was administered (3 min) intravenously. Background corrected gallbladder ejection fractions (GBEFs) were determined every 5 min X 4 by rationing the pre-CCK GB counts minus post-CCK GB counts to pre-CCK GB counts. GBEFs were: 12% (3 patients), 17% (2), 0%, 1.3%, 3%, 4%, 6%, 11%, 14%, 18.5%, and 22% (1 each). All patients underwent a surgical exploration and all had macro- or microscopically abnormal cystic ducts with (12 patients) or without (2 patients) concomitant chronic cholecystitis. No patient with a partially occluded cystic duct with or without concomitant chronic cholecystitis had an ejection fraction that exceeded 22%. In an appropriate clinical setting, a low EF response to CCK should alert the physician to the presence of either chronic acalculous cholecystitis, CDS, or the combination of both.

  18. Scintiscanning in the evaluation of biliary enteric anastomoses

    1985-03-01

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

  19. New attempts using computed tomography in determining indication of gallstone dissolution therapy

    1987-03-01

    Subjects for this study were 32 patients who had radiolucent stones in the gallbladder disclosed by conventional cholecystography. In all 12 patients with complete or partial dissolution of gallstones by gallstone dissolution therapy, the gallstone features on the CT scan were shown as an iso-density or a low-density in contrast to the bile, whereas, in 20 unresponsive patients, they were shown as shells of high-density in 9 out of 20 patients, and as a high-density in contrast to the bile in 7 out of 20 patients. If the gallstones contained 1.0 to 4.0 % of calcium, the calcification could not be detected by conventional radiographic examinations, but could be clearly detected by CT examinations. In the present study, we concluded that the patients with gallstones containing more than 1 % of calcium were not suitable for dissolution therapy and that CT examinations were very useful for deciding about using dissolution therapy of the gallstones.

    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.

    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.

    Gall-bladder visualization on oral cholecystography (OCG) is required for most non-surgical therapies of gallstones. In this study we attempted to establish sonographic criteria which will predict non-visualization of the gall-bladder on OCG. For this purpose we compared the results of ultrasound (US) and OCG in 171 patients with gallstones being assessed for non-surgical therapy. Sonographic criteria for non-visualization were a contracted gall-bladder and stone impaction in the gall-bladder neck or cystic duct. In detecting findings which predict non-visualization on OCG, US had a sensitivity of 78.3% and a specificity of 97.6%. The predictive values were: positive findings 92.3% and negative findings 92.4%. The overall accuracy was 92.4%. We conclude that US can be used as a first step in selecting patients for non-surgical therapy and if US indicates a contracted gall-bladder, 11% of the patients can be excluded from further diagnostic imaging.

  3. Radiologic and ultrasonographic diagnosis of gallstones.

    1988-01-01

    Several new nonsurgical modes of therapy for gallstone disease are being introduced almost simultaneously in the United States. These include orally administered bile acids, contact dissolution with methyl t-butyl ether (MTBE), and extracorporeal shock wave lithotripsy. Paralleling these developments is a similar period of transition in the field of gallstone imaging. Technical considerations in performing ultrasonographic, roentgenographic, and cholecystographic studies become more important, since the criteria for use of the nonsurgical techniques place a greater emphasis on gallstone morphology. In ultrasonography, sizing artifacts from reflective surfaces, optimizing measurements, magnifying hard-copy images, positioning the patient, and optimizing transducer frequencies will need to be addressed. In roentgenography, coned views of the right upper quadrant, with the patient prone, will give the best results. Oral cholecystography (OCG) has largely been replaced by ultrasonography for the detection of gallstones, but it is still an essential part of the imaging workup because it permits adequate visualization of the gallbladder to assure patency of the cystic duct. Correlation of the findings from the several techniques has disclosed new insights and encouraged the use of tailored techniques. Based on the current criteria for the use of orally administered ursodeoxycholic acid, an estimated 60-70% of all patients who have gallstones may be suitable candidates for such treatment.

    The appropriate selection of patients for treatment with oral ursodeoxycholic acid (UDCA)--a drug that has virtually no side effects--results in about 50% of patients experiencing safe dissolution of gallstones within 2 years. Eligible patients have small (less than 20 mm in diameter) radiolucent gallstones in a gallbladder visualized by oral cholecystography (OCG); ideal candidates are thin women who have gallstones that are less than 15 mm in diameter, floating when observed by OCG, or of low density on computed tomographic (CT) scanning. Contact dissolution with methyl tert-butyl ether (MTBE) is rapid, effective more often than UDCA, and safe but requires the expertise of an interventional radiologist. Any size and number of cholesterol gallstones that are not CT-dense will be dissolved by MTBE, leaving at most only insoluble debris that is clinically innocuous. Although gallstones recur after dissolution by UDCA or MTBE in 50% of patients within 5 years, recurrent gallstones are usually asymptomatic and/or can probably be dissolved. We conclude that oral or contact dissolution provides an alternative treatment to cholecystectomy for about 30% of patients with symptomatic gallstones. PMID:8480875

    Chemical composition of gallstones is of major importance in selecting patients for nonsurgical therapy. In a combined in vivo and in vitro study of predictive potential, 50 patients undergoing cholecystectomy were evaluated with computed tomography (CT) and either plain abdominal radiography or oral cholecystography (OCG). The largest stone surgically removed from each patient was subjected to in vitro CT and chemical analysis. The authors found an inverse relationship between CT attenuation numbers and cholesterol content and a good positive correlation between CT attenuation numbers and calcium content. In vivo CT analysis improved sensitivity, specificity, accuracy, and positive and negative predictive values compared to plain abdominal radiography and OCG in detection of cholesterol stones. Using their prediction rule (a CT number smaller than 140 HU indicates a pure cholesterol gallstone), the authors correctly classified gallstones in 17 (84%) of another 20 patients. In vivo CT analysis can enable reliable prediction of gallstone composition and should play an important role in the selection of patients for nonsurgical treatment. PMID:2296642

    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

    The evaluation of symptomatic patients who have undergone biliary enteric anastomoses, particularly when the diversion was into the jejunum, is difficult. Conventional techniques for evaluation, such as oral cholecystography (OCG), intravenous cholangiography (IVC), ultrasonography (US), computer-assisted tomography scanning (CT scanning), or endoscopy are not adequate to provide definitive information on the patency of the anastomoses. Hepatobiliary scintiscanning using 99mTc-HIDA and BIDA (iminodiacetic acid derivatives) was performed on 12 patients. The patients were from 11 to 72 years of age and included ten men and two women. The scan results were correlated with US, CT scan, percutaneous transhepatic cholangiography (PTC), operative findings, and final diagnosis. Scanning was highly accurate in this group and could be performed successfully even in jaundiced patients (total serum bilirubin level up to 20.0 mg/dl). In patients in whom dilated bile ducts were demonstrated (by US, CT scan, or scintiscan), only the scintiscan revealed the true patency of the anastomoses. The advantages of the technique are that it is simple and noninvasive. Delayed transit of bile (scanning agent) to bowel is a very reliable indication of partial or complete obstruction. Scintiscanning is the only technique that demonstrated the functional state of biliary secretion and excretion into bowel in patients with previous biliary enteric anastomoses. PMID:3883866

    Since radiographic findings on oral cholecystography (OCG) have implications for the eligibility for nonsurgical therapy of elderly patients, we investigated the OCGs of 448 symptomatic gallstone patients (109 male, 339 female; mean age, 49.8 +/- 14 (range, 21-88)). Opacification of the gallbladder was found in 323 cases (72.1%). Calcifications of gallstones were found in 85 opacified gallbladders (26.3%). Solitary and multiple stones were calcified in 35.3% and 18.2%, respectively (P 40 years), there was a significant increase in calcifications (P < 0.02) and a non-significant increase in opacification with increasing age. It is concluded that age is a determinant for calcification of gallstones and not opacification of the gallbladder. Since multiple stones are proportionately observed more in clinical studies than in epidemiologic studies, it is suggested that multiplicity of stones predisposes to biliary complaints. That solitary stones are more likely to be calcified than multiple stones, adds to the hypothesis that solitary and multiple stones have a different pathogenesis. Elderly patients, in whom non-surgical therapy is most likely to be indicated and cost-effective, are less likely to be suitable for this form of treatment, since age is a determinant for stone calcification.

    Topical dissolution of cholesterol gallbladder stones using methyl tert-butyl ether (MTBE) is useful in symptomatic patients judged too ill for surgery. Previous studies showed that ethyl propionate (EP), a C5 ester, dissolves cholesterol gallstones rapidly in vitro, but differs from MTBE in being eliminated so rapidly by the liver that blood levels remain undetectable. Our aim was to test EP as a topical dissolution agent for cholesterol gallbladder stones. Five high-risk patients underwent topical dissolution of gallbladder stones by EP. In three patients, the solvent was instilled via a cholecystostomy tube placed previously to treat acute cholecystitis; in two patients, a percutaneous transhepatic catheter was placed in the gallbladder electively. Gallstone dissolution was assessed by chromatography, by gravimetry, and by catheter cholecystography. Total dissolution of gallstones was obtained in four patients after 6-10 hr of lavage; in the fifth patient, partial gallstone dissolution facilitated basketing of the stones. In two patients, cholesterol dissolution was measured and averaged 30 mg/min. Side effects were limited to one episode of transient hypotension and pain at the infusion site; no patient developed somnolence or nausea. Gallstone elimination was associated with relief of symptoms. EP is an acceptable alternative to MTBE for topical dissolution of cholesterol gallbladder stones in high-risk patients. The lower volatility and rapid hepatic extraction of EP suggest that it may be preferable to MTBE in this investigational procedure.

  11. Medical radiation exposure and usage for diagnostic radiology in Malaysia

    International Nuclear Information System (INIS)

    A national dose survey of routine X-ray examinations in Malaysia (a Level II country) from 1993 to 1995 had established baseline data for seven common types of x-ray examinations. A total of 12 randomly selected public hospitals and 867 patients were included in this survey. Survey results are generally comparable with those reported in the UK, USA and IAEA. The findings support the importance of the ongoing national quality assurance programme to ensure doses are kept to a level consistent with optimum image quality. The data was useful in the formulation of national guidance levels as recommended by the IAEA. The medical radiation exposure and usage for diagnostic radiology (1990-1994) enabled a comparison to be made for the first time with the UNSCEAR 2000 Report. In 1994, the number of physicians, radiologists, x-ray units and x-ray examinations per 1000 population was 0.45, 0.005, 0.065 and 183, respectively; 3.6 million x-ray examinations were performed; the annual effective dose per capita was 0.05 mSv and collective dose was 1000 person-Sv. Chest examinations contributed 63% of the total. Almost all examinations experienced increasing frequency except for barium studies, cholecystography, and intravenous urography (-23%, -36%, -51%). Notable increases were observed in computed tomography (161%), cardiac procedures (190%), and mammography (240%). (author)

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

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

    Tests for liver function have by and large centered around clinical laboratory diagnostic procedures for a number of years. Besides these, radiographic imaging procedures, including oral cholecystography and intravenous cholangiography, serve a very useful purpose, but several of them are invasive and involve a certain degree of risk from the administered contrast media as well as discomfort to the patient. The cholescintigraphic procedures, though noninvasive, have not played a significant role in the evaluation of hepatobiliary disorders prior to the introduction of the currently available /sup 99m/Tc-labeled IDAs. These new hepatobiliary agents offer many advantages over the previously utilized radiopharmaceuticals (/sup 131/I-rose bengal in particular) in terms of the high degree of specificity for localization in the gallbladder with rapid extraction rates by the polygonal cells of the liver and very low excretion via the GU tract. A detailed understanding of the structure distribution relationship of the various groups in the complex enable the design of agents with an improvement in hepatobiliary specificity and other desirable characteristics. In many clinical situations, even in patients with high bilirubin levels, the /sup 99m/Tc-labeled IDAs offer far superior clinical information over the alternative diagnostic imaging modalities. Further, the absorbed radiation dose imparted to the critical organs is far lower than with the older agents. Thus, the introduction of the cholescintigraphic procedures with the /sup 99m/Tc-labeled IDAs have ushered in a new phase in the diagnostic workup of patients with impaired hepatocellular function and other biliary disorders.

    Oral cholecystography is one of the most reliable and widely used x-ray examination which enables us to observed not only morphological features of the gallbladder (GB) but also functioning state. It was disclosed that functional evaluation of the GB is mandatory to recognize such kinetic disorders of the viscus as acalculous cholecystitis or dyskinesia. For the purpose of functional evaluation, fat meal has been used traditionally. Recently, cholecystokinin (CCK) and ceruletide were introduced into clinical diagnosis of the GB, the usefulness of which we have confirmed. In the present study we have made an attempt at improving cholecystagogic effect of conventional fat meals(FM) such as whole milk and egg yolk by changing the posture of the examined from sitting up to right decubitus position after the ingestion of fat meal. The hypothesis involved in this study is that the presence of quantitatively more fat meal in the duodenum per unit time may result in more effective cholecystagogic action and such a setting would be created by enhancement of pyloric passage of fat meal by decubitus posturing. Clinical materials consisted of 280 normal oral GB series (136 males and 144 females) and they were divided into 4 equally numbered groups of milk sitting and milk decubitus and egg sitting and egg decubitus. Upon confirming satisfactory opacification of the GB 11 hours after the ingestion of 3 g of sodium ipodate or iopanoic acid either 2 pieces of medium sized hen's egg yolk were given. The xaminess were than allowed either sitting up comfortably on a bench or lying down on the right flank on a couch. After the ingestion of fat mean, x-ray was taken at the end of 30 minutes in all but the milk decubitus group in which x-rays were taken serially at the end of 5, 15, 30 and 60 minutes. The frontal area of each opacified GB was measured by using a planimeter and the contraction rate before and after fat meal stimulation was calculated by the following equation and

    In the present communication, the results will be reported on a clinical study of how well scintigraphic visualization of the hepatobiliary elements and several commonly used clinical liver function tests correlate each other in various diseases of hepatobiliary system. The demonstrability of the biliary tract, gallbladder (GB) and duodenum was rather closely paralleled to serum bilirubin level and less closely to alkaline phosphatase and rather poorly to SGOT and SGPT. The usefulness of {sup 99m}Tc-EHIDA [N-(2,6-diethylacetanilido) iminodiacetic acid, made by Amersham, England] hepatobiliary scintigraphy (Tc EHIDA HBS) in settling diagnostic controversy and ambiguity raised by oral cholecystography, intravenous cholangiography and ultrasonography in many hepatobiliary diseases is well known. The purpose of this investigation was to semiquantitatively evaluate the scintigraphy demonstrability of the hepatobility tract, GB and duodenum following intravenous injection of {sup 99m}Tc-EHIDA in normal subjects and in patients with a disturbed liver function from various hepatobility diseases. The hepatobiliary scintigraphy was performed in 10 normal subjects and 39 patients with various hepatobiliary diseases (Table 1) at the Dept. of Radiology, St. Mary's Hospital Catholic Medical College, Seoul, Korea during 2 years period from September 1979. Scintigraphy examination was started at end of 3 minutes after intravenous injection of {sup 99m}Tc-EHIDA in the amount of 50 muCi/kg and was continued until after 30 minutes at 5 minutes interval. The imaging was usually terminated when the tracer could be seen in the duodenum. Late scintigrams were obtained at 1 1/2, 2, 3, 4 and 6 hours when needed. Scintigrams were analyzed in terms of promptness and clarity of visualization of the biliary tree, GB and duodenum and demonstrability of these anatomical landmarks was correlated with the values of liver function tests.

    Oral cholecystography is a reliable and the most popular clinical examination. The examinations is not suitable for morphological study of the gallbladder but also efficient in diagnosing acalculous cholecystitis and cystic duct syndrome and some ill defined functional disorders. For the functional evaluation of the gallbladder fat meal stimulation has been used traditionally. Recently, however, potent cholecystagogues called cholecystokinin (CCK) and ceruletide were introduced in the radiological examination of the gallbladder stimulating acute interest in research of acalculous cholecystitis and cystic duct syndrome. The present study has been undertaken to test both experimentally and clinically the cholecystokinetic effects of CCK and ceruletide. In addition, the study has been designed to test if pharmacological constriction of the Oddi sphincter with morphine in animal and prostigmine in human subjects promotes visualization of the common bile duct and hopefully the common hepatic duct. Seen (7) mongrel dogs weighing 10 kg were anesthesized with Pentothal sodium (20mg/kg body wt) in the evening allowed to swallow 2 g of lopanoic acid (Telepaque) per os. Twelve hours later in the next morning dogs were radiographed of their upper abdomen in LAO. Upon confirming optimal opacification of the GB 0.03 {mu} g/kg of CCK was injected intravenously to each of the 7 mongrel dogs for the test of contraction-rate and contraction-time of the gallbladder. The same test was repeated after injecting 10 mg/dog of morphine to strict the Oddi sphincter. The clinical materials consisted of 30 normal human subjects and 60 patients with biliary symptoms and signs.

    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

    Full Text Available Objective: the aim of this study was to evaluate the incidence, clinical features and role of laparoscopic cholecystectomy (LC in patients with chronic acalculous cholecystitis (CAC in comparison with a control group of patients who underwent cholecystectomy for chronic calculous cholecystitis (CCC. Material and methods: prospective evaluation of 34 patients with CAC in contrast with 297 patients with CCC. Outcome measures: clinical presentation, quality of life using the Gastrointestinal Quality of Life Index (GIQLI, usefulness derived from the therapeutic procedure as measured in quality of life units by GIQLI, and clinical efficacy at one year of follow-up. Results: the incidence of complicated biliary disease was higher in CAC (27%, in comparison with CCC (13.8%. The histological study of the excised gallbladder revealed a higher incidence of cholesterolosis associated with chronic cholecystitis in the CAC group (64.9%. GIQLI showed significant differences between preoperative and postoperative measurements in both groups.
