Biliary dyskinesia refers to a group of functional and motility disorders of the biliary system in patients presenting with typical biliary pain, but without any visible structural abnormalities on standard imaging. The Rome IV Criteria establishes diagnostic criteria for functional gallbladder disorder (gallbladder dyskinesia and biliary hyperkinesia), functional biliary sphincter of Oddi disorder (biliary dyskinesia), and pancreatic sphincter of Oddi disorder. Many diagnostic adjuncts such as hepatobiliary scintigraphy and sphincter of Oddi manometry exist, although these results are supportive and not necessarily diagnostic for biliary dyskinesia. Surgical intervention is most successful when selecting for patients with typical biliary pain., Competing Interests: Disclosure The author has nothing to disclose., (Copyright © 2024 Elsevier Inc.

Background: Biliary dyskinesia (BD) is a common indication for cholecystectomy in children. Current literature demonstrates an improvement in symptoms after cholecystectomy in most pediatric patients with an EF <35%; however, data supporting the efficacy of cholecystectomy for hyperkinetic BD (EF >65%) is sparse. We sought to determine whether children with hyperkinetic BD (HBD) had resolution of their symptoms after laparoscopic cholecystectomy at our institution., Materials and Methods: We conducted a retrospective chart review of children who had undergone laparoscopic cholecystectomy for HBD at our institution between September 2010 and July 2015. Patients completed a phone survey about symptom resolution, whether they were happy to have undergone cholecystectomy, overall satisfaction on a 1-10 scale, and additional workup for those with ongoing pain. Analysis was performed using STATA statistical software with a P-value < 0.05 as statistically significant., Results: Thirteen patients met inclusion criteria. Median gallbladder ejection fraction was 93% [IQR: 90, 97]. Median postoperative follow-up was 59 d [IQR: 25, 151] at which time 50% reported resolution of symptoms. Eight patients participated in the survey at a median follow-up of 45 mo [IQR: 40, 66]. Fifty percent reported ongoing abdominal pain. Frequency of pain varied among patients with pain, occurring from <1 time per week to a few times per day. Five patients (63%), including one patient with ongoing pain, were happy that their gallbladder had been removed and overall satisfaction rating was 5 on a scale of 1-10., Conclusions: Only half of children with HBD were asymptomatic at long-term follow-up. Cholecystectomy for HBD may or may not improve symptoms., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Background: Gallbladder dyskinesia (gallbladder spasm, biliary dyskinesia or chronic acalculous cholecystitis) is a poorly defined entity which presents as biliary-type pain without any identifiable organic pathology. Abnormal gallbladder ejection fraction (GBEF) is used by some to select those likely to benefit from cholecystectomy. The validity of this approach has been questioned., Aim: To systematically review the literature and summarise the evidence surrounding the practice of cholecystectomy based on GBEF for gallbladder dyskinesia., Methods: We conducted a systematic search of PubMed/MEDLINE and SCOPUS from 1980 to 2016 to identify the relevant literature., Results: Twenty-nine studies including 2891 patients were included in the final analysis. In comparing cholecystectomy with medical management, patients with a normal GBEF did not benefit from cholecystectomy; whereas those with low GBEF had a higher chance (RR, relative risk = 2.37) of symptomatic improvement following surgery. When those classified as "low" and "normal" GBEF were compared in terms of outcome following cholecystectomy, the rate of improvement following surgery was similar in the two groups (RR 1.09) which suggests a placebo effect of surgery., Conclusions: While a low GBEF may provide some guidance in identifying those with gallbladder dyskinesia who may benefit from cholecystectomy, the available data are inconsistent and based on studies of poor quality which are often subject to bias and the impact of confounding factors. For these reasons, we conclude that the role of scintigraphy and cholecystectomy in the definition and management of this disorder remain unclear pending definitive study., (© 2019 John Wiley & Sons Ltd.)

Purpose of Review: Gallstone disease is a major epidemiologic and economic burden worldwide, and the most frequent form is cholesterol gallstone disease., Recent Findings: Major pathogenetic factors for cholesterol gallstones include a genetic background, hepatic hypersecretion of cholesterol, and supersaturated bile which give life to precipitating cholesterol crystals that accumulate and grow in a sluggish gallbladder. Additional factors include mucin and inflammatory changes in the gallbladder, slow intestinal motility, increased intestinal absorption of cholesterol, and altered gut microbiota. Mechanisms of disease are linked with insulin resistance, obesity, the metabolic syndrome, and type 2 diabetes. The role of nuclear receptors, signaling pathways, gut microbiota, and epigenome are being actively investigated., Summary: Ongoing research on cholesterol gallstone disease is intensively investigating several pathogenic mechanisms, associated metabolic disorders, new therapeutic approaches, and novel strategies for primary prevention, including lifestyles.

Background: Twenty percent of cholecystectomies in the US are performed for a diagnosis of biliary dyskinesia. Diagnosis is made by measuring gallbladder ejection fraction (GbEF) using hepatobiliary scintigraphy. Our purpose was to evaluate the reproducibility of GbEF measurements., Study Design: This is a retrospective review of patients referred for cholecystectomy, from 2010 to 2016, with a diagnosis of biliary dyskinesia based on a GbEF test, who then underwent a repeat GbEF test. Thirty consecutive patients were identified by hospital records. Re-testing of GbEF was performed at least 6 weeks after the initial test using Tc-99m and slow injection of sincalide at 0.02 mcg/kg., Results: On re-testing, 16 of 30 patients (53%) patients had a normal GbEF of >35%, ie the initial test result was not reproducible in them. Age, sex, days between testing, and initial GbEF did not differ between groups. The 14 patients who re-tested positive for biliary dyskinesia with reduced GbEF were significantly more likely to have episodic pain than steady pain. Re-testing frequently resulted in change in management in that most patients who re-tested in the normal range were not offered cholecystectomy., Conclusions: Hepatobiliary scintigraphy with GbEF is a poorly reproducible test. Re-testing resulted in a change in management in many patients who then avoided cholecystectomy. Strong consideration should be given to repeating hepatobiliary scintigraphy with GbEF before cholecystectomy in patients with an initial positive test., (Copyright © 2017 American College of Surgeons.

The prevalence of gallstones is 10% to 15% in adults. Individuals with acute cholecystitis present with right upper quadrant pain, fever, and leukocytosis. Management includes supportive care and cholecystectomy. The prevalence of choledocholithiasis is 10% to 20%, and serious complications include cholangitis and gallstone pancreatitis. The goal of management in individuals with choledocholithiasis consists of clearing common bile duct stones. Acute ascending cholangitis is a life-threatening condition involving acute inflammation and infection of the common bile duct. Treatment includes intravenous fluids, analgesia, intravenous antibiotics, and biliary drainage and decompression. Biliary dyskinesia includes motility disorders resulting in biliary colic in the absence of gallstones., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: Despite the increasing use of fatty meal (FM) as a substitute for cholecystokinin (CCK) in pain reproduction during hepato-imino-diacetic acid (HIDA) scan in functional gallbladder disorder, there are no studies comparing the differences between CCK and FM. The present study was to compare the efficacy of FM in comparison of CCK in FGBD application., Methods: Patients undergoing HIDA scans from August 2013 to May 2014 were divided into two groups: those undergoing CCK-stimulated HIDA scan versus FM-stimulated HIDA scan. These groups were compared according to demographics and HIDA results., Results: Of 153 patients, 70 received CCK and 83 FM. There was no difference regarding age, gender, gallstones, gallbladder ejection fraction and time to visualization. However, significantly more of the patients receiving CCK than FM experienced pain reproduction (61% vs 30%, P<0.01)., Conclusions: Stimulation of gallbladder contractility with a FM during HIDA is less than half as likely to reproduce biliary symptoms compared to CCK, despite similar ejection fractions and other parameters. It is essential that providers account for this difference when counseling patients regarding cholecystectomy for functional gallbladder disorder.

Background: Rates of cholecystectomy for biliary dyskinesia are rising. Our objective was to identify clinical determinants of symptom improvement in children undergoing cholecystectomy for biliary dyskinesia., Methods: This retrospective cohort study included patients undergoing cholecystectomy for biliary dyskinesia from 2006-2013 who had their gallbladder ejection fraction (EF) measured by either cholecystokinin-stimulated hepatobiliary iminodiacetic acid scan and/or fatty meal ultrasound. Patients presenting from 2010-2013 were interviewed >1 y after cholecystectomy to determine symptom improvement, complete symptom resolution, and any postoperative clinical interventions related to biliary dyskinesia. Sensitivity and positive predictive values for the diagnostic tests for symptom improvement were calculated. Multivariable logistic regression models were used to identify preoperative characteristics associated with symptom improvement., Results: Of the 153 included patients, 76% were female, 89% were Caucasian, and 39% were obese. At postoperative evaluation, symptom improvement was reported by 82% of the patients and complete symptom resolution in 56%. For both the hepatobiliary iminodiacetic acid and fatty meal ultrasound, the sensitivity of the test to predict symptom improvement increased with higher EF, whereas the positive predictive values remained around 80%. Of the 41 patients who participated in phone interview for long-term follow-up, 85% reported symptom improvement and 44% reported complete symptom resolution. Factors associated with symptom improvement included a shorter duration of pain, a history of vomiting, and a history of epigastric pain., Conclusions: Despite not identifying an EF level that predicted symptom improvement, over 80% of patients undergoing cholecystectomy for biliary dyskinesia reported symptom improvement. These results support continuing to offer cholecystectomy to treat biliary dyskinesia in children., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Background/aims: Hepatobiliary Iminodiacetic Acid (HIDA) scan provides a technique to quantify gallbladder ejection fraction (EF) in patients suffering acalculous biliary colic (ACBC). We wished to evaluate the accuracy of EF in the prediction of gallbladder pathology in patients undergoing cholecystectomy., Methods: Data were retrieved from a database of patients referred for HIDA scan for ACBC, including EF and the pathological outcome of those undergoing cholecystectomy, and compared to normal values obtained from a review of related studies. Significant associations were demonstrated by chi-square, Mann-Whitney test, and linear regression. The predictive accuracy of different cut-offs of EF was demonstrated by the ROC curve analysis., Results: Of 83 patients referred for HIDA scan for ACBC, 41 underwent cholecystectomy. The median EF of this group (33%) was significantly lower than the composite normal median value from previous studies (56%). Thirty-two patients revealed evidence of gallbladder pathology. The EF declined with age (coefficient = -0.51, 95% CI = -0.99 to -0.33), but the median value did not differ between those with gallbladder pathology (34%) and those with normal gallbladders (29%)., Conclusion/discussion: Although an EF cut-off of 35% had the greatest accuracy in the prediction of pathology of those tested (0.56), the poor negative predictive value (23.5%) was a major contributor to its low accuracy. Although patients with ACBC have reduced gallbladder EF compared to the normal population, its quantitative assessment is of limited value in the prediction of gallbladder pathology.

Biliary dyskinesia (BD) is a diagnosis that is being made increasingly in children. It is defined by abdominal pain thought to be biliary in nature based on location and character; a completely normal gallbladder on imaging tests, typically ultrasound; and decreased gallbladder contraction in response to a pharmacological stimulus. Unlike other functional gastrointestinal disorders (FGIDs) that are treated with medications, behavioral therapy, and/or dietary modification, current clinical practice has accepted cholecystectomy as the treatment of choice for BD, which now accounts for up to 50% of cholecystectomies in children. Although well-designed trials are missing, accumulating evidence argues against such an approach. First, BD is by definition a benign disorder without risk of truly relevant complications. Second, despite reportedly high rates of satisfaction with postoperative outcomes, most children continue to experience symptoms. Lastly, limited long-term studies have demonstrated comparable benefit of operative and conservative therapy. To summarize, BD should be seen as a more localized manifestation of functional abdominal pain, which may improve over time independent of the type of therapy chosen. Despite the widespread adoption of minimally invasive surgery in pediatrics, a different risk-benefit ratio favors conservative treatment for this benign disorder., (Copyright 2014, SLACK Incorporated.)

Purpose: Biliary dyskinesia (BD) is described as biliary colic in the absence of gallstones. The diagnosis relies on imaging studies and decreased excretion of bile in response to cholecystokinin during quantitative cholescintigraphy. The purpose of this study was to evaluate the success of laparoscopic cholecystectomy (LC) for relieving symptoms in patients diagnosed with BD and correlate gallbladder ejection fraction (EF) with symptom relief., Methods: A retrospective review was performed at a single institution of all patients who underwent LC for BD from January 2005 through January 2012. The diagnosis of BD was determined by a normal gallbladder as viewed with ultrasonography and cholescintigraphy with a gallbladder EF less than or equal to 45%. Data collection included demographics, results of imaging studies, pathologic diagnosis, and early postoperative pain relief. Patients were contacted by phone after being discharged from the surgeon's care for evaluation of symptom relief. Data were analyzed with nonparametric statistical methods, including Mann-Whitney U test, receiver operator characteristic, Fisher exact test, and χ(2) test. All data are expressed as median and 25th and 75th percentile range., Results: There were 126 patients who had a LC for BD during the study period. The median biliary EF was 20% (10-29%). The most common pathologic finding was chronic cholecystitis (n = 95; 75%). Median length of follow-up in the perioperative period was 11 days (8-17), during which time 98 patients (78%) had relief of symptoms. Phone interviews (n = 53; 42%) confirmed 66% (n = 35) of patients remained free of pain. There was no difference in the mean EF among those with resolution of pain 20% (10-29%) compared with patients with persistent pain 23% (11-29%), P = .62. Obese patients were more likely to have persistent symptoms in the perioperative period with a shift to lower body mass index at the time of the phone survey. Receiver operator characteristic characteristic for the association between scintigraphic EF and resolution of postoperative pain demonstrated no association, with the area under the curve equal to 0.47., Conclusion: The majority of patients in this series with BD had resolution of symptoms with LC. However, cholescintigraphy EF did not correlate with outcome. Further studies are needed to better identify patients diagnosed with BD who will benefit from LC., (Copyright © 2013 Mosby, Inc.

Cholecystectomy may benefit children with biliary colic without stones on ultrasound (US) or low ejection fraction on cholecystokinin-hepatobiliary iminodiacetic acid (CCK-HIDA) scan. Children with symptomatic biliary colic and abnormal HIDA scan, specifically those with high ejection fractions, may benefit from cholecystectomy. All patients younger than 18 years old undergoing cholecystectomy from 2008 to 2012 in our practice were reviewed. Patients with a negative US and CCK-HIDA ejection fractions 80 per cent or greater were included in the study. Patient data were extracted from charts, whereas postoperative symptoms were obtained by phone interviews. Of 174 patients who underwent cholecystectomy, 12 (7%) met study criteria. All patients (12 of 12) had evidence of cholecystitis on the final pathology note. All 11 patients contacted had relief of colic after gallbladder removal with a mean follow-up of 16 months. A subset of pediatric patients with high ejection fractions on CCK-HIDA and symptomatic biliary colic may have symptomatic relief with cholecystectomy.

Despite the identical content of mebeverine hydrochloride, Duspatalin and Niaspam, produced by different technological processes, can't be considered interchangeable as they are known to have different clinical effect in case of various functional diseases of alimentary organs. Duspatalin is effective in relieving biliary disfunction symptoms, Oddy's sphincter hypertonicity in particular, but has little effect on intestinal dyskinesia. Niaspam is known to have little effect on biliary dyskinesia, but has a prominent positive clinical effect on intestinal dyskinesia.

Background: Biliary dyskinesia diagnosed with CCK-HIDA scan and ejection fraction less than 35 % has been successfully treated by laparoscopic cholecystectomy. However, a population of patients with symptomatic biliary pain and a normal CCK-HIDA scan never receive a diagnosis, and thus no definitive treatment. Some of these patients report a reproducible pain during their CCK-HIDA scan. It is hypothesized that these patients have a novel diagnosis, normokinetic biliary dyskinesia, and may have resolution of pain when treated with cholecystectomy., Methods: A retrospective chart review was completed looking for patients with biliary pain in accordance with the ROME III criteria. Additional inclusion criteria were (1) greater than age 18 years, (2) reproducible biliary symptoms during the CCK-HIDA scan, and (3) an ejection fraction greater than 35 %. Treatment modality was laparoscopic cholecystectomy. Descriptive statistics were preformed, and data were reported as mean ± standard deviation and range., Results: Nineteen patients met the inclusion criteria for this study from August 2008 to July 2011. There were 15 women and 4 men with a mean age of 48.4 ± 13.0 years. The mean ejection fraction was 75.1 ± 19.4 %. The average duration of preoperative symptoms was 6.8 ± 5.9 months and postoperative follow-up was 21.8 ± 10.6 months. Seventeen patients had complete resolution of symptoms, one had partial resolution, and one had no change. There was a complete resolution rate of 89.5 % and an improvement rate of 94.7 %., Conclusions: We suggest that patients who present with biliary pain, a normal CCK-HIDA scan with an ejection fraction greater than 35 %, and with reproducible symptoms on infusion of CCK could have a novel diagnosis: normokinetic biliary dyskinesia. Currently, these patients are excluded from the diagnosis of biliary dyskinesia and thus treatment. We hypothesize a potential new diagnosis, suggest cholecystectomy as treatment, and recommend a prospective study design for further evaluation.

Background/aims: The aim is to compare the radionuclide (DC) and ultrasonographic (US) method in the assessment of gallbladder (GB) motility., Methodology: The study was performed in 15 controls (C), 10 patients with acute cholecystitis (AC), 20 patients with chronic acalculous cholecystitis (CAC), 26 patients with chronic cholecystitis with calculosis (CCC) as well as in 15 patients with GB dyskinesia (D). GB emptying period (EP), ejection fraction (EF) and ejection rate (ER) were estimated with dynamic cholescintigraphy (DC) and US., Results: The DC and US finding in the patients with AC was typical in all the patients, i.e. GB was not visualized at all on DC, while on US, stone was visible in the cystic duct. There were significant differences (p<0.05) between the EF and ER values obtained between C and the three groups of patients CAC, CCC and D, using both methods. However, there were no significant differences in EF, EP and ER values among CAC, CCC and D (p>0.05). There was also high correlation between the results obtained with both methods in all the groups of patients studied., Conclusions: The results obtained by both methods are valuable for the assessment of GB motility. Although there are no significant differences and there is a high correlation between the values, radionuclide method is more precise, because it can register motility continuously.

Aim: Decreased gallbladder ejection fraction (GBEF) was reported in patients who had abdominal pain and gastrointestinal (GI) diseases. The study aims were to review pathology of GI tract in children with acalculous biliary-type abdominal pain and to evaluate the pain improvement after a 2-week trial of proton pump inhibitor (PPI) and laparoscopic cholecystectomy (LC)., Methods: Children below 18 years of age with a history of biliary-type abdominal pain by ROME III criteria were evaluated. All underwent an upper endoscopy and their histologic findings of the proximal GI tract were reviewed. Responses to a 2-week trial of PPI and LC were analyzed., Results: Sixteen were identified with biliary-type abdominal pain with GBEF <35%. Endoscopic and histologic evidence of reflux esophagitis was observed in 11 children those of gastritis in 3 children. A GI pathology of these children is mostly acid-related and four of ten children experienced a complete response to PPIs and did not require LC. Nine children had LC; four had complete and four had partial pain improvement., Conclusion: A trial of PPIs may be cost-effective prior to considering LC in these patients since four of ten children experienced a complete response to PPIs without the requirement of LC, compared with four of nine children who improved completely.

Objective: The purpose of this study was to determine the efficacy of 3D and 4D ultrasound in correlation with hepatoiminodiacetic acid (HIDA) scanning for calculating gallbladder ejection fraction (EF)., Subjects and Methods: A prospective study was conducted with 40 adult patients with suspected gallbladder dyskinesia. Cholecystokinin-provoked (99m)Tc-HIDA scintigraphy was performed, and concurrent 3D and 4D ultrasound images of the gallbladder were obtained before cholecystokinin infusion and 20, 30, and 40 minutes after infusion. The EF values calculated from the ultrasound images and HIDA scan were compared., Results: The gallbladder EF values (mean ± standard error of the mean) calculated 20 minutes after cholecystokinin infusion from HIDA scans and 3D and 4D ultrasound images were 54.1% ± 5.0%, 58.9% ± 6.3%, and 62.8% ± 5.5%. Thirty minutes after infusion the EF values were 56.3% ± 4.7%, 56.9% ± 5.7%, and 59.1% ± 4.6%. The numbers of patients with an EF less than 50% were 14, 12, and 13, and the numbers with an EF less than 35% were 10, seven, and eight. For the patients with an EF less than 50%, the kappa agreement between HIDA scanning and 3D ultrasound was 0.89 (95% CI, 0.73-1.00), between HIDA scanning and 4D ultrasound was 0.83 (95% CI, 0.65-1.00), and between 3D and 4D ultrasound was 0.83 (95% CI, 0.64-1.00)., Conclusion: Both 3D and 4D ultrasound techniques correlate well with HIDA scanning for calculating gallbladder EF in patients with suspected biliary dyskinesia.

Background: The (99m) technetium labelled hepato imino diacetic acid (HIDA) scan is widely used in the investigation of patients with typical biliary pain but whose trans-abdominal ultrasound scan (US) is normal. Although the standard measure by which the HIDA scan is deemed positive is the presence of an ejection fraction (EF) of <35% following provocation with cholecystokinin (CCK), there still remains debate as to the usefulness of this measure. The aim of this study was to compare the roles of EF and symptom provocation following CCK infusion in relation to the outcome following laparoscopic cholecystectomy (LC). More specifically, we aimed to review the resolution of symptoms for our significant population of patients with normal HIDA scan EFs for whom surgery has traditionally been deemed inappropriate., Patients and Methods: All patients undergoing LC for a presumed diagnosis of biliary dyskinesia were identified from a prospectively maintained database. Data were collected regarding pre-operative symptoms, EF and symptom provocation during the CCK HIDA scan, histological findings, early symptomatic outcome, and medium-term follow-up., Results: During the period from March 2006 to October 2009, 42 patients with biliary symptoms but a negative US were referred for assessment by a single surgeon. There were 31 women and 11 men with a mean age of 39.0 ± 12.6 years. All underwent a CCK HIDA scan of which 17 were positive with an EF <35% and the remaining 25 were negative. All patients reported recreation of symptoms following administration of CCK. All gallbladders were delivered intact for histological assessment and all but one showed evidence of chronic cholecystitis. At each postoperative visit, approximately 2 weeks following the procedure, all patients reported resolution of symptoms. After a mean of 18.7 ± 12.1 months symptom recurrence had been noted in only one of 42 (2.4%)., Conclusions: The CCK HIDA scan is a useful study in the investigation of acalcalous cholecystitis; however, we would suggest that recreation of symptoms following CCK provocation is superior to EF for the identification of underlying chronic cholecystitis. Indeed, a normal gallbladder ejection fraction does not necessarily rule out a biliary aetiology of symptoms for this patient population.

The objective of this work was to develop a scientifically sound rationale for the method of reflex correction of biliary tract dysfunction based on chronobiological data concerning functioning of the acupuncture points corresponding to biliary ducts. It was shown that patients presenting with biliary dyskinesia (i.e., forming desynchronism) experience a shift of both skin temperature and electrical resistance at the acupuncture points. The chronoreflexotherapeutic technique employed in this study makes it possible to rapidly restore disturbed biorhythms of functioning of the biliary system, normalize the motor-evacuating activity of the gallbladder, and eliminate clinical manifestations of the disease.

Cholesterol gallstone formation is a complex process and involves phase separation of cholesterol crystals from supersaturated bile. In most cases, cholesterol hypersecretion is considered the primary event in gallstone formation. The sterol is transported through the hepatocytic canalicular membrane by ABCG5-G8. Expression of this transport protein is regulated by transcription factor Liver X Receptor-alpha, which may be responsible for biliary hypersecretion. Hydrophobic bile salt pool, bile concentration, excess pronucleating mucin, and impaired gallbladder and intestinal motility are secondary phenomena in most cases but nevertheless may contribute to gallstone formation., (Copyright 2010 Elsevier Inc.

Functional gallbladder disorder, commonly referred to as gallbladder dyskinesia, is characterized by the occurrence of abdominal pain resembling gallbladder pain but in the absence of gallstones. The diagnosis and management of this condition can be confusing even for the most astute clinician. The aim of this article is to clarify the identification and management of patients with suspected functional gallbladder disorder., (Copyright 2010 Elsevier Inc. All rights reserved.)

Unlabelled: Years of experience observing children with GSD made possible to determine the clinical course and to clarify some of mechanisms of postcholecystectomical syndrome formation in children. Material and methods. There were observed 148 children who underwent cholecystectomy at the age of 3 to 15 years. There were 44 boys and 104 girls. Diagnosis refined was conducting by ultrasonography, magnetic resonance imaging. Degree of biliary insufficiency was assessed based on dynamic of gepatobilliarscintigraphy. The clinical picture of disease was assessed according to age and sex of the child., Results: We described the clinical course and pathogenetic mechanisms of postcholecystectomical syndrome in children in the age aspect. Based on the results of our research, were found ways of correction of postcholecystectomical syndrome in children with cholelithiasis.

Was developed screening test for early diagnosis of various biliary dysfunction. It is based on determining of elektrodermal resistance and temperature of skin in biologically active points. A new method of diagnosis hasn't contraindications, not require the use of expensive or complicated equipment.

Functional disorders of the biliary tract include gallbladder dyskinesia (GBD) and sphincter of Oddi dysfunction (SOD). The diagnosis of GBD is made if the gallbladder ejection fraction is less than 35% to 40% using cholecystokinin cholescintigraphy. Despite slightly inferior outcomes compared with calculous disease, patients who have GBD should be treated with cholecystectomy. SOD is most often noted in the postcholecystectomy patient and symptoms can be biliary or pancreatic in nature. The gold standard for diagnosis remains manometry, with basal biliary or pancreatic sphincter pressures measuring greater than 40 mm Hg. Patients who have increased pressures may benefit from endoscopic sphincterotomy.

Purpose: To determine gallbladder volume with sonography during fasting and in response to a fatty meal in patients with spinal cord injuries (SCIs) and compare the results with those obtained in healthy controls., Method: Forty-three patients with SCI and 40 healthy volunteers without clinical evidence of gallbladder disease underwent sonography before and 30 and 60 minutes after the ingestion of a standard fatty meal. The gallbladder fasting volume, resting volume, and gallbladder contractility were calculated, and the results were compared. Correlation between gallbladder contractility and level of lesion, time since injury, use of oxybutynin, and body mass index (BMI) was also assessed., Results: The mean ejection fraction was significantly lower in the patients with SCIs (40%) compared with healthy controls (63%) (p < 0.001). Gallbladder mean residual volume 60 minutes after ingestion of the fatty meal was lower in the control group (p < 0.001)., Conclusion: Gallbladder contractility is impaired in patients with SCI, which may predispose these patients to gallstone formation. There was no correlation between gallbladder contractility and level of the lesion, time since injury, use of oxybutynin, or BMI.

Introduction: This study was designed to compare symptomatic outcomes following cholecystectomy in patients with biliary dyskinesia., Materials and Methods: From 1999 to 2006 at New York University Medical Center, 197 adults underwent hepatobiliary scintigraphy with cholecystokinin administration to evaluate gallbladder ejection fraction (GBEF). Biliary dyskinesia was demonstrated in 120 patients based on decreased GBEF of

Approximately 30 per cent of patients who undergo cholecystectomy for biliary dyskinesia will continue to have symptoms after surgery. Quality of life has not been evaluated but may be decreased in these patients. The purpose of this study was to measure quality of life after laparoscopic cholecystectomy in these patients to better define optimal treatment of biliary dyskinesia. All patients with biliary dyskinesia (defined as the absence of gallstones, and a gallbladder ejection fraction of <35%) who underwent cholecystectomy at our institution from January 31, 2000 to January 31, 2005 were identified. Preoperative data including ultrasound, biochemical data, and pathology were retrieved by chart review. Postoperative assessment included the Gastrointestinal Quality of Life Index and a symptom survey. The postoperative quality of life was compared with historic standards. The quality of life was also compared with preoperative variables to determine if any variables predicted outcome. A total of 66 patients were identified as fitting the inclusion criteria. Forty-three patients were reached by phone and 30 agreed to participate. Patients were noted to have good recall as to preoperative symptoms when the retrospective survey of symptoms was compared with the medical record. The mean +/- SD postoperative quality of life in the study population was 113 +/- 20. This is higher than in historic patients with gallbladder disease before (84 +/- 19) and after (102 +/- 13) cholecystectomy. Quality of life in the study group was lower than the healthy control (125 +/- 13). Patients having both postprandial nausea and vomiting before surgery had a lower quality of life (P < 0.029) after surgery as compared with those without these preoperative symptoms. When adjusted for nausea and vomiting, the quality of life in study patients (119 +/- 14) was similar to normal controls. No other symptom, laboratory, pathologic, or sonographic data were predictive of a lower quality of life. Cholecystectomy is beneficial for most patients with biliary dyskinesia. Nausea and vomiting were negative predictors of quality of life after cholecystectomy. These patients with nausea and vomiting may have a global gastrointestinal motility disorder and are less likely to benefit from cholecystectomy.

Perendoscopic biliary manometry may not represent the overall sphincter of Oddi (SO) motility, as the recording time is relatively short and it is possibly influenced by the presence of an endoscope in duodenum and air inflation. Percutaneous transhepatic biliary manometry of SO permits long-term recordings without patient discomfort and risk of complications. We investigated the change of human SO motility and the correlation between SO motility and migrating motor complex (MMC) of the small bowel in a fasting state by long-term simultaneous manometric examination of SO and small bowel. During long-term manometry, MMC-like cyclic activities of SO were observed, which considered to be MMC of SO. It coordinated well with MMC of the small bowel, except that SO was not quiescent during phase I MMC of the small bowel. In addition, the basal pressure of SO changed in accordance with the phases of SO motility. Percutaneous transhepatic biliary manometry also permits prolonged manometric studies to investigate normal physiologic reflexes such as gastroduodeno-sphincteric, cholecysto-sphincteric and choledocho-sphincteric reflexes, and the influence of cholecystectomy on SO motility in humans.

Aim: To study function of the liver, sphincter system and the gall bladder (GB) in patients with biliary dyskinesia (BD)., Material and Methods: Thirty-four patients with BD have undergone clinical, fibrogastroduodenoscopic examinations, fractional duodenal intubation with examination of the bile, ultrasonography, dynamic scintigraphy of the hepatobiliary system., Results: The examination of the patients has detected GB hypotonia (65%), GB hypertension (35%), Oddi's sphincter hypertention (28%), Oddi's sphincter hypotonia (44%), Lutkens' sphincter hypertonicity (19%), Lutkens' sphincter hypotonia (13%), impairment of intrahepatic biliary tracts (65%), lithogenic bile (100%), duodenogastric reflux (41%)., Conclusion: Consecutive use of duodenal tubing, ultrasonography and hepatobiliscintigraphy provide assessment of defects in the function of the liver, biliary tract and sphincter system in patients with BD.

The study of 67 chronic biliary patients (36 - gallbladder dysfunction, 25 acalculuous cholecystitis, 6 - cholelithiasis) was revealed their functional dysadaptation characterized by gallbladder dysmotility and autonomic dysfunction. Vegetotropic therapy (Propranolol, Metoclopramid, Atropine) according to the autonomic regulation activity has advantages in correction of the gallbladder dysmotility in comparison to the routine pharmacotherapy. Hypobaric hypoxic adaptation results in the increase of gallbladder emptying that opens perspectives for the non-pharmacological correction of the gallbladder hypokinetic dyskinesia.

Aim: Biliary dyskinesia (BD) is characterized by symptoms of biliary disease, no evidence of gallstones on ultrasonography (USG), and diminished gallbladder ejection fraction. The diagnosis is based on findings of abnormal gallbladder ejection fraction diagnosed by hepatobiliary scintigraphy before and after stimulation of gallbladder contraction with cholecystokinin (CCK). We used an easier diagnostic technique defined as ultrasonographic evaluation of fatty meal stimulated gallbladder contraction, employing USG with the diagnosis of biliary dyskinesia in children. The study was conducted by USG to investigate the volume and contractility of the gallbladder (GB) in fasting conditions and 45 min after a standardized fatty meal (SFM) in normal children and in a group of BD patients, and to compare the diagnostic value of this test with scintigraphy and to evaluate its use as a new method in the diagnostic algorithm of BD., Methods: We assessed the volume changes and contractility of the GB in response to SFM by USG in 14 patients with BD diagnosed by cholecystokinin stimulated hepatobiliary scintigraphy (CCKs-HBS); and compared them with 14 control patients matched for age and gender before cholecystectomy. After an overnight fasting, GB volume was measured by USG then the GB volume was again measured after the SFM ingestion. Using USG, length, width and height of GB were measured, and volume of the GB was calculated using the 'Dodds' formula. These volume measurements were used to calculate the percentage of gallbladder emptying (ejection fraction). Fasting, after SFM and EF values comparisons between groups were done with student's t-test., Results: No statistically significant difference of fasting GB volumes were demonstrated between BD and control groups (14.1+/-6.7 cm3 and 13.4+/-4.0 cm3 respectively). GB volumes of the BD group after SFM were significantly greater than in healthy controls (13.1+/-1.8 cm3 and 3.4+/-0.9 cm3 respectively, P<0.0005). The calculated percentage of gallbladder contraction (ejection fraction) was found to be lower in BD patients than in healthy controls (7.1%+/-1.8% and 73.8%+/-6.4%, respectively, P<0.0005)., Conclusion: Ultrasonographic evaluation of fatty meal stimulated gallbladder contraction provides relatively reliable and reproducible results. Thus it can be used for scanning in patients with biliary symptoms as a prior modality to CCK-HBS since it is a relatively easier, safer and available method with which to make a definitive diagnosis of BD. The patients with symptoms of biliary disease and no evidence of gallstones on USG should be evaluated by the method proposed in this study before the routine laboratory and radiologic tests.

The aim of this paper was to describe functional biliary syndromes and methods for evaluation of the biliary tract in these patients. Functional biliary symptoms can be defined as biliary symptoms without demonstrable organic substrate. Two main syndromes exist: Gallbladder dysfunction and sphincter of Oddi dysfunction. The most important investigative tools are cholescintigraphy and endoscopic sphincter of Oddi manometry. In gallbladder dysfunction a scintigraphic gallbladder ejection fraction below 35% can select patients who will benefit from cholecystectomy. Endoscopic sphincter of Oddi manometry is considered the gold standard in sphincter of Oddi dysfunction but recent development in scintigraphic methods is about to change this. Thus, calculation of hilum-to-duodenum transit time and duodenal appearance time on cholescintigraphy have proven useful in these patients. In conclusion, ambient methods can diagnose functional biliary syndromes. However, there are still a number of issues where further knowledge is needed. Probably the next step forward will be in the area of sensory testing and impedance planimetric methods.

Morphofunctional state of the gall bladder and Oddi's sphincter was studied in 188 patients with stomach ulcer treated surgically for different complications of this disease. It is demonstrated that patients with stomach ulcer have dysfunction of the gall bladder before surgery, and in long-term period after stomach resection (especially by Bilrot-II technique) functional disorders transform in organic ones.

Biliary dyskinesia is defined as symptomatic biliary colic without cholelithiasis, and is diagnosed during cholescintigraphy by assessing gallbladder emptying with cholecystokinin (CCK) stimulation. Unfortunately, gallbladder emptying is not routinely assessed during cholescintigraphy in pediatric patients. The purpose of this review is to assess the effectiveness of cholecystectomy in patients with chronic abdominal pain and delayed gallbladder emptying and to assess whether these findings correlate with the histologic evidence of chronic cholecystitis. We retrospectively reviewed the medical records of all patients ( n=16) at our institution from October 1997 to August 2001 who underwent quantitative cholescintigraphy with CCK stimulation that demonstrated delayed gallbladder emptying (< 35% at 60 min) and who subsequently underwent cholecystectomy. Laparoscopic cholecystectomy was performed in 16 patients with chronic abdominal pain. All 16 patients had delayed gallbladder emptying (mean ejection fraction: 15+/-8%, range: 3-32%). The mean age was 12+/-2 years (range: 8-17 years). Presenting symptoms included abdominal pain (86%), fatty food intolerance (27%), emesis (13%), and diarrhea (13%). Mean duration of abdominal pain before operation was 11+/-19 months (range: 2 weeks-6 years). One patient's symptoms persisted postoperatively, but abdominal pain resolved in all other patients. Histologic evidence of chronic cholecystitis was demonstrated in 86% of surgical specimens. Five patients underwent concurrent appendectomy, and all had normal appendiceal histology. Our experience suggests that children with chronic abdominal pain and delayed gallbladder emptying on CCK-stimulated cholescintigraphy are likely to benefit from cholecystectomy and to have histologic evidence of chronic cholecystitis.

Heart syndrome features associated with pain, the structure of myocardial ischemia and heart rate derangement were studied in patients with ischemic heart disease (IHD) and concomitant biliary dyskinesia (BD). It was established that BD considerably aggravates clinical course of IHD: increase in frequency of pain and painless episodes of myocardial ischemia in patients with stable exertional angina I-II functional classes by NYHA and single supraventricular and ventricular extrasystoles.

Corinfar-Retard efficacy in patients with hypertonic-hyperkinetic type of biliary dyskinesia has been studied. 56 patients aged 26 to 30 had been prescribed Corinfar-Retard in 20 mg per day for 7 days. Dynamic echocholecystography has applied. Decrease in contraction of gall bladder and normalization of tonic contraction of sphincter Ody was found in the patients with previously diagnosed hypertonic-hyperkinetic type of biliary dyskinesia after having been treated with Corinfar-Retard.

We report our experience of cholecystectomy for treating symptoms suggestive of biliary disease in association with a decreased gallbladder ejection fraction (GBEF) but without evidence of cholelithiasis. Five children with normal biliary ultrasounds were evaluated between January 1990 and December 2000 for recurrent upper abdominal pain. Based on a cholecystokinin (CCK)-provoked GBEF of less than 50% and the absence of any other gastrointestinal pathology, patients underwent cholecystectomy with operative cholangiography for presumed biliary dyskinesia. Pathological examination demonstrated chronic inflammation in all cases. Two patients had complete resolution of their symptoms, but three had persistent pain following surgery. Biliary dyskinesia seems an uncommon cause of persistent abdominal pain in childhood. Cholecystectomy was not always effective in relieving symptoms. Biliary scintigraphy with CCK provocation should not be used as the sole criterion for cholecystectomy. Sphincteric manometry may be valuable in the assessment of this small group of patients to avoid inappropriate intervention. The future perhaps lies in better understanding of the physiological action and pharmacological control of the sphincter of Oddi.

The therapeutic efficacy of tykveol was evaluated in 22 patients with chronic non-calculous cholecystitis and/or dyskinesia of the biliary tract (BT) concurrent with gallbladder deformity (GD). Supplementation of tykveol to the combined therapy in the patients with chronic non-calculous cholecystitis concurrent with GD was shown to exert a pronounced therapeutic effect. This caused positive changes in clinical symptoms and BT function, diminished the lithogenic propertes of bile. With the use of tykveol, recovery of neurohumoral regulation is an important factor that improves biliary tract function, as evidenced by decreased gastrin secretion.

Biliary pain is commonly reported in household surveys with the presumed cause being gallstones. When gallstones are absent or other abnormalities as a potential cause of similar pain do not exist, a different approach is necessary. Although trans-abdominal ultrasound can detect stones down to 3-5 mm, the advent of endoscopic ultrasound provides an even better definition for microlithiasis of < 3 mm. Duodenal aspiration of bile can further detect cholesterol microlithiasis or bilirubin granules, another potential source of biliary-type pain and perhaps even pancreatitis. Only in this way can acalculous gallbladder disease be clearly defined. The percentage of cholecystokinin-stimulated gallbladder emptying has been reputed to be the most sensitive diagnostic test for 'biliary dyskinesia', but abnormality of gallbladder emptying can be due to a smooth muscle defect of the gallbladder itself or heightened tone in the sphincter of Oddi. The value of surgical intervention has not been clearly established. The advent of laparoscopic cholecystectomy, however, has increased the number of patients with acalculous biliary disease who undergo surgery. Surgery is best done using impaired gallbladder emptying as the criterion for operation with improved outcome. Often, following cholecystectomy, biliary pain does not resolve the so-called 'post cholecystectomy syndrome'. Absence of the gallbladder as a pressure reservoir leaves the sphincter of Oddi as the prime determinant of bile duct pressure. Sphincter of Oddi dysfunction also exists in patients with an intact biliary tract and may become evident following cholecystectomy. Biliary manometry has clarified who might benefit from sphincterotomy. Choledochoscintigraphy is a non-invasive preliminary test. Advent of visceral hypersensitivity and better definition of this entity has shown, that in some of these patients with type III sphincter of Oddi, dysfunction appears to reside in duodenal hyperalgesia. It is clear that improved criteria are required to perform gallbladder emptying and better techniques to detect visceral hypersensitivity. Nonetheless, functional biliary pain in the absence of gallstone disease is a definite entity and a challenge for clinicians.

The aim was to study psychovegetative disorders in hypomotor and hypermotor forms of biliary diskinesia (BDK) in young patients. Psychological status and vegetative nervous function were studied in 62 patients with hypoBDK, 58 patients with hyperBDK and 33 control patients. According to AMPI, Spilberger's, Aizek's, Heck-Hess' tests, the psychological status of the patients from both groups was similar, while vegetative status in the hypoBDK group at rest and active orthostasis had a sympathetic trend. In hyperBDK group at rest sympathetic impacts enhanced, in stress these impacts intensified reaching higher values than in the control group. For the treatment of various forms of BDK, it is recommended to correct psychovegetative deviations with consideration of diskinesia forms.

Biliary dyskinesia (BD) is a well-recognized cause of chronic abdominal pain in adults, but is less common in children. We reviewed our experience with the diagnosis, treatment, and follow-up in a group of children treated with cholecystectomy from March 1995 to October 2000. We identified children with chronic upper abdominal pain, normal ultrasonography (US), and delayed cholecystokinin (CCK)-stimulated gallbladder emptying (<35%). All other diagnostic tests for their abdominal pain were reviewed. Their treatment, surgical intervention, and outcome were recorded. During the study period, 74 cholecystectomies were performed in our institution, 10 (13.5%) of them for BD. The duration of symptoms ranged between 1 and 60 months (mean 22). All patients had a normal plain abdominal radiograph, normal US, and delayed gallbladder ejection fraction (EF). All were treated by elective laparoscopic cholecystectomy. Symptoms were completely relieved in all patients during the follow-up period, which ranged between 9 and 24 months (mean 12.8). Cholecystectom should be considered in children with chronic upper-abdominal pain and delayed EF on CCK-HIDA scintigraphy. Laparoscopic cholecystectomy is the procedure of choice in these patients.

The aim of the present study was to evaluate the influence of the exogenous nitric oxide donor glyceryl trinitrate on cerulein-induced gallbladder contraction in patients with acalculous biliary pain. Quantitative hepatobiliary scintigraphy was performed on 33 patients. From the 60th min cerulein (1 ng/kg body wt/min for 10 min intravenous) then from the 90th min the same dose of cerulein plus glyceryl trinitrate (0.5 mg sublingually) (21 patients) or placebo (12 patients) were administered and the gallbladder ejection fraction was measured repeatedly. After the first dose of caerulein, the gallbladder ejection fraction was less than 35% in 23 of 33 patients (nonresponders), while it was more than 35% in the remaining 10 patients (responders). After the second dose of cerulein in 16 nonresponder patients glyceryl trinitrate administration significantly increased the previously impaired gallbladder ejection fraction while in 7 nonresponder patients placebo administration had no effect. In conclusion, normalization of the gallbladder ejection fraction in the majority of patients following glyceryl trinitrate administration suggests that impairment of gallbladder emptying is caused by a functional motility disorder rather than any organic disease.

The group of 117 patients (58 male and 57 female, age from 17 to 54) with chronic non-calculous cholecystitis was examined. The control group included 54 practically healthy persons. The motor-evacuation function of gallbladder was estimated on dynamic ultrasonographic findings of biliary system sorbet. The character of the autonomic regulation was determined on the basis of variability parameters of the heart rhythm. The results of the repeated dynamic ultrasonography of biliary system with sorbet on a background of vegetotropic medications (Atropine, Propranolol, Metoclopramide) have demonstrated that the variability parameters of heart rhythm can be used for an estimation of the autonomic regulation type and can become the basis of vegetotropic pharmacotherapy choice for the patients with chronic non-calculous cholecystitis and biliary dyskinesia.
