Cholecystectomy for Biliary Hyperkinesia.

Patients with classic biliary colic symptoms and documented gallbladder ejection fractions on the higher end of the spectrum on hepatobiliary iminoacetic acid scans with cholecystokinin stimulation are presently understudied and the benefits of cholecystectomy are unclear. To determine whether patients with biliary-type pain and biliary hyperkinesia (defined as a gallbladder ejection fractions of 80% or greater) benefit from laparoscopic cholecystectomy, a retrospective chart review encompassing five community hospitals was performed. Patients 16 years and older with diagnosed biliary hyperkinesia who underwent laparoscopic cholecystectomy between January 1, 2010 and May 31, 2015 were included. Pathology reports were reviewed for histologic changes indicating cholecystitis. Resolution of biliary colic symptoms was reviewed one to three weeks after surgery in their postoperative follow-up documentation. Within our study cohort, we found 97 patients who underwent laparoscopic cholecystectomy for biliary hyperkinesia. Within this population, 84.5 per cent of patients undergoing laparoscopic cholecystectomy for biliary hyperkinesia had positive findings for gallbladder disease on final pathology. Of the 77 patients with data available from their first postoperative visit, 70 (90.9%) reported improvement or resolution of symptoms. Our findings suggest that symptomatic biliary hyperkinesia may be treated successfully with surgery.

Ex vivo magnifying endoscopic observation of bile duct mucosa using narrowband imaging.

BACKGROUND: Detailed endoscopic findings of the bile duct mucosa have not been fully established. This fundamental ex vivo study assesses the relationship between magnified endoscopic findings and pathological findings of the bile duct mucosa. METHODS: Forty-one surgically resected common bile duct mucosae were investigated. Each common bile duct was cut open longitudinally for ex vivo endoscopic observation. A magnifying endoscope commonly used for the gastrointestinal tract was used, using both white light imaging and narrowband imaging. After pathological diagnosis, the association between the magnifying endoscopic findings and histopathology was evaluated. RESULTS: Totally, 39 non-neoplastic mucosae and 13 neoplastic mucosae were evaluated. In 13 non-neoplastic mucosae without inflammation, an oval-shaped depressed area and a fine, regular network of microvessels were observed. These findings were not clearly seen or not seen at all in the non-neoplastic mucosae with inflammation. Although vessels with loop-like structure were observed on all eight papillary tumors of 13 neoplastic mucosae, no characteristic vessels were seen on the other five. CONCLUSIONS: Ishida and colleagues assessed the association between magnifying endoscopic findings and histopathological findings of the bile duct mucosa ex vivo. Oval-shaped, depressed areas and a fine, regular network of microvessels are characteristic features of normal bile duct mucosa, while loop structures may be indicative of a type of tumor vessel.

Gallbladder Ejection Fraction Is Unrelated to Gallbladder Pathology in Children and Adolescents.

OBJECTIVES: Biliary dyskinesia is a common diagnosis that frequently results in cholecystectomy. In adults, most clinicians use a cut off value for the gallbladder ejection fraction (GBEF) of <35% to define the disease. This disorder is not well characterized in children. Our aim was to determine the relation between GBEF and gallbladder pathology using a large statewide medical record repository. METHODS: We obtained records from all patients of 21 years and younger who underwent hepatic iminodiacetic acid (HIDA) testing within the Indiana Network for Patient Care from 2004 to 2013. GBEF results were obtained from radiology reports using data mining techniques. Age, sex, race, and insurance status were obtained for each patient. Any gallbladder pathology obtained subsequent to an HIDA scan was also obtained and parsed for mention of cholecystitis, cholelithiasis, or cholesterolosis. We performed mixed effects logistic regression analysis to determine the influence of age, sex, race, insurance status, pathologist, and GBEF on the presence of these histologic findings. RESULTS: Two thousand eight hundred forty-one HIDA scans on 2558 patients were found. Of these, 310 patients had a full-text gallbladder pathology report paired with the HIDA scan. GBEF did not correlate with the presence of gallbladder pathology (cholecystitis, cholelithiasis, or cholesterolosis) when controlling for age, sex, race, insurance status, and pathologist using a mixed effects model. CONCLUSIONS: Hypokinetic gallbladders are no more likely to have gallbladder pathology than normal or hyperkinetic gallbladders in the setting of a patient with both a HIDA scan and a cholecystectomy. Care should be used when interpreting the results of HIDA scans in children and adolescents.

Hepatobiliary phase of gadoxetic acid-enhanced MR in patients suspected of having gallbladder dyskinesia: comparison with hepatobiliary scintigraphy.

OBJECTIVE: To compare hepatobiliary phase of gadoxetic acid-enhanced magnetic resonance (HMR) and hepatobiliary scintigraphy (HBS) for evaluation of cystic duct patency and gallbladder contractility in patients suspected of having gallbladder dyskinesia. MATERIALS AND METHODS: Eighteen patients underwent HMR and HBS. Cystic duct patency and gallbladder ejection fraction (GBEF) were compared to determine a significant difference between HMR and HBS. RESULTS: HMR and HBS had 15 concordant and 3 discordant results for cystic duct patency. GBEF in eight patients showed no significant difference between both modalities. CONCLUSION: HMR may be an alternative to HBS for the functional evaluation of cystic duct patency and GBEF.

[Imbalance of microelements and vitamins in adolescents with diffuse nontoxic goiter and biliary dyskinesia].

The purpose of the present work was to study the level of microelements and vitamins in adolescents with diffuse nontoxic goiter. It has been shown that comorbid biliary dyskinesia leads to significant dysregulation of vitamin and mineral metabolism: the level of essential elements was decreased and the level of toxic elements was increased. Comorbid biliary dyskinesia in adolescents with diffuse nontoxic goiter was accompanied by a disbalance of vitamins. The changes found in micronutrients have sex differences.

Biliary dyskinesia and symptomatic gallstone disease in children: two sides of the same coin?

BACKGROUND: Despite lack of consensus criteria, biliary dyskinesia (BD) is an increasingly accepted pediatric diagnosis. AIMS: We compared patient characteristics, outcomes, and resource utilization (before and after surgery) between children with BD and symptomatic cholecystolithiasis (LITH). METHODS: Data from the electronic medical record were abstracted for children diagnosed with BD or LITH between December 1, 2002, and November 30, 2012, at Children's Hospital of Pittsburgh. RESULTS: Four hundred and ten patients were identified (BD: 213 patients, LITH: 197 patients). Patients with BD had significantly lower BMI, longer symptom duration, more dyspeptic symptoms, and were more likely to present with other symptoms. Forty-one patients (13.8%) with BD underwent cholecystectomy despite a normal gallbladder ejection fraction (GB-EF). In 32 of these, sincalide triggered pain compared to 75 of the 155 patients with low GB-EF. After surgery, patients with BD more commonly visited gastroenterology clinics and had more GI-related hospitalizations, while emergency room visits decreased in both groups. Only the nature of biliary disease independently predicted continuing pain after surgery, which in turn was the best predictor for higher resource utilization after cholecystectomy. CONCLUSIONS: A large percentage of children with BD did not meet the adult diagnostic standards. Compared to those with LITH, children with BD have more widespread symptoms and continue to use more clinical resources after surgery. These findings suggest that despite its benign prognosis, BD is increasingly treated like other potentially acute gallbladder diseases, although it has the typical phenotype of FGIDs and should be treated using approaches used in such disorders.

Is biliary scintigraphy a reliable diagnostic tool for biliary dyskinesia in children?

BACKGROUND AND AIM: The role of hepatobiliary scintiscan (HIDA) in children suspected to be having functional biliary tract disease has not been studied. We evaluated HIDA scan results as long-term prognostic indicators for biliary dyskinesia with or without intervention. METHODS: Children who had HIDA scan for chronic abdominal pain, nausea, or vomiting were included. These children had inconclusive gastrointestinal diagnostic workup. HIDA scan was performed according to a standardized protocol. Clinical data were collected by retrospective chart review. A telephonic survey was done 5 years after the initial HIDA scan to document long-term outcome. RESULTS: Forty-two of 61 children had abnormal HIDA scan. There was no difference between children with normal and abnormal HIDA results in clinical presentations, short-term (85.7% and 84.2%) and long-term (64.9% and 60%) outcomes. Twenty-seven of the 42 children with abnormal scan results underwent interventions (21 cholecystectomy only, 4 cholecystectomy followed by sphincter of Oddi sphincterotomy, and 2 sphincterotomy only). After intervention, children with abnormal HIDA scan had better short-term prognosis (88.9% and 54.5%), but their long-term prognosis (52.2% and 85.7%) was worse than those without intervention. No clinical prognostic factor could be identified. CONCLUSIONS: HIDA scan result is not a good prognostic indicator in children with suspected biliary dyskinesia. Caution should be exercised while using HIDA scan for selecting patients for surgical intervention. Focused prospective studies are needed to define biliary dyskinesia in children.

Pathologic changes in biliary dyskinesia.

PURPOSE: For children with upper abdominal pain and evaluation for acalculous biliary disease, laparoscopic cholecystectomy is an accepted treatment with inconsistent outcomes. The purpose of this study was to identify predictors of outcomes. METHODS: One hundred sixty-seven children underwent laparoscopic cholecystectomy at a single children's hospital. Radiographic findings, histopathology, family history, and demographics (sex, age, height, weight, body mass index-for-age percentile) were evaluated as predictors of postoperative symptomatic resolution using a binomial probability model. The data for radiologic studies and pathologic specimens were obtained via re-review in a blinded fashion. RESULTS: Of 167 children, 43 (25.7%) had a preoperative diagnosis of biliary dyskinesia and 41 (95.3%) had documented follow-up. Mean follow-up was 8.4 months. Twenty-eight patients (68.3%) had symptom resolution. Ejection fraction less than or equal to 15%, pain upon cholecystokinin injection, and a family history of biliary disease were not predictors of symptomatic resolution. Nonoverweight patients (body mass index-for-age <85th percentile) were more likely to have symptom resolution than their overweight counterparts (odds ratio, 2.13). Most patients (68.3%) had a pathologic gallbladder on blinded review. However, this did not correlate with outcome. CONCLUSIONS: Most gallbladders removed for biliary dyskinesia are pathologic. Being overweight can be considered a relative contraindication to cholecystectomy for biliary dyskinesia.

The use of tenoten preparation in complex therapy of hypomotoric biliary dyskinesia.

A positive effect of tenoten on the course of biliary dyskinesia in patients with anxiety and depressive disorders was demonstrated. Tenoten can be recommended for the treatment of functional cholangio-pancreatoduodenal motility disturbances.

[Pathogenetic basis of pharmaceutical hepatitis induced by depakine in children].

42 children with epilepsy receved treatment by depakin drug. We defined the factors of lipid exchange processes of liver and their correlation between itself and with changes in immune status. The results of the studies indicated shaping the medical hepatitis with cholestatic syndrome on background of the long acceptance of depakin. Metabolic desadaptation was conditioned by glicolis activation in the condition of the oxygen deficit in tissue.

Gallbladder wall inflammatory cells in pediatric patients with biliary dyskinesia and cholelithiasis: a pilot study.

BACKGROUND/PURPOSE: Inflammation has been implicated in functional gastrointestinal disorders, including functional dyspepsia and irritable bowel syndrome. This study was undertaken to evaluate gallbladder wall inflammatory cells in children with abdominal pain related to gallstones and biliary dyskinesia to determine the candidate cell types that may be contributing to the pathophysiology of these entities. METHODS: Gallbladder specimens from 20 patients with cholelithiasis, 20 biliary patients with dyskinesia, and 12 autopsy controls were evaluated in a blinded fashion. Eosinophil, tryptase-positive, and CD3+ cell densities were determined for the lamina propria and muscularis mucosa layers and compared between groups. RESULTS: Patients with biliary dyskinesia and cholelithiasis had a 9- to 12-fold increase in mean and peak mast cell densities, respectively, in both layers as compared with controls. Peak (13.7 vs 8.4) and mean (9.2 vs 5.2) CD3+ cell densities were increased in the muscularis mucosae of cholelithiasis specimens as compared with biliary dyskinesia specimens. CONCLUSION: Gallbladder wall inflammatory cell densities, particularly mast cells, differ between children with cholelithiasis, children with biliary dyskinesia, and controls. Future studies are warranted to define the roles for specific inflammatory cell types.

Evaluation of hepatic functions and biliary dynamics in patients with liver cirrhosis by quantitative scintigraphy.

BACKGROUND/AIMS: Aim of the study is to determine the changes in hepatocyte and gallbladder motor functions, and biliary dynamics in patients with liver cirrhosis. METHODOLOGY: The study group consisted of 17 patients with liver cirrhosis (12 males, 5 females) who were diagnosed by clinical, laboratory and histopathologic findings. Control group consisted of 20 healthy persons (14 males, 6 females). Quantitative hepatobiliary scintigraphy was performed by using Tc99m-Mebrofenin i.v. and dynamic images were obtained and evaluated quantitatively by computer. Maximum excretion time of radiodiagnostic agent by liver (Tmax) and half excretion time of radio-diagnostic agent from liver (T 1/2), gallbladder filling time, gallbladder ejection fraction and the transit time of bile to duodenum were determined. RESULTS: Mean values of Tmax was 25.76 vs. 12.40 min, T 1/2 was 37.55 vs. 23.15 min, gallbladder filling time was 53.35 vs. 30.57 min, and transit time of bile to duodenum was 39.88 vs. 25.00 min in the patients and control group, respectively. These values increased significantly in the patient group (p < 0.05) compared to controls. Mean gallbladder ejection fraction was 37.55% in the patient group and 41.84% in the control group without any statistical significance (p > 0.05). The incidence of gallbladder stone was 29.41% in the cirrhosis group and 5% in the control group (p < 0.05). CONCLUSIONS: The quantitative hepatobiliary scintigraphy is a simple and reliable method in evaluation of hepatic functions and biliary dynamics in cirrhotic patients. Although the incidence of gallbladder stone is significantly increased in cirrhotic patients, it seems that a stone in the gallbladder does not affect the gallbladder motor functions.

Biliary dyskinesia and biliary crystals: a prospective study.

The management of patients with biliary colic without gallstones has remained controversial in part because a mechanism for "biliary dyskinesia" has not been elucidated. A prospective study was done on patients presenting with biliary colic symptoms but without demonstrable gallstones. Thirty-six patients were evaluated with ultrasound and hepatobiliary/cholecystokinin scintigraphic scanning. Patients with gallbladder ejection fractions of less than 35 per cent and/or symptoms reproducible with cholecystokinin were offered cholecystectomy. At cholecystectomy, bile was aspirated from the gallbladder for crystal analysis. A random sample of 36 patients with gallstones undergoing cholecystectomy were analyzed as a control group. Pathologic evaluation was done; the gallbladder wall was examined using polarized microscopy to determine the presence of crystals within the gallbladder wall. The mean gallbladder ejection fraction in patients without stones was 24.1 per cent and in patients with stones, 34.6 per cent (P = 0.14). 89.7 per cent of patients without stones had crystals in their gallbladder bile. 61.8 per cent of patients without stones and 81.3 per cent of patients with stones (P = 0.22) had crystals within their gallbladder walls. 94.1 per cent of patients without stones and 100 per cent of patients with stones (P = 0.49) had pathologic evidence of chronic cholecystitis. These data suggest that a spectrum of biliary disease exists in which bile saturation and gallbladder dysmotility lead to crystal growth and subsequent gallstone formation and chronic inflammation. Biliary pain may be generated at any point in this spectrum.

[Gallbladder contractility in early stages of lithogenesis in the lithogenic fed guinea pig]. / Gallenblasenkontraktilität in frühen Stadien der Lithogenese am Modell des lithogen ernährten Meerschweinchens.

The main aim of our study was the investigation of gallbladder motility prior to gallstone formation in vivo in guinea pigs fed a lithogenic diet. In a first experiment guinea pigs were fed a lithogenic diet for 5, 15, 30 and 45 days. First gallstones (pigment calculi) appeared after 30 days diet application. The in vitro contractility after lithogenic diet remained unchanged. In a second experimental part the in vivo gallbladder contractility was measured in two experimental animal groups (control group and 21 days lithogenic fed guinea pigs). The isovolumetric pressure rise inside the gallbladder following the intravenous injection of 10(-9) mol/kg body weight ceruletid was the essential contractility parameter (intraluminal basal pressure 5 mm hg). Due to lithogenic feeding of 21 days--that means prior to gallstone formation--the isovolumetric pressure rise was significantly elevated (p < 0.01). Moreover we observed passive distensibility changes of gallbladder muscle due to muscular hyperplasia. The main result of this investigation is the fact that gallbladder muscle in guinea pigs fed a lithogenic diet response to ceruletid application with hypercontractility prior to provable pigment gallstone formation. However gallbladder hypomotility--believed to be a causal factor in cholelithogenesis--was not observed in our experimental conditions.

[A point about obstructive non-neoplastic pathology of the duodeno-biliary-pancreatic junction]. / Il punto sulla patologia ostruente non neoplastica del giunto duodeno-bilio-pancreatico.

Various benign pathological conditions of Oddi's sphincter may give origin to clinical manifestations due to hindrances to biliary flow into the duodenum; the hypertonic dyskinesia, proper, odditis and fibrosclerotic dystrophies. Such forms develop very big problems from a diagnostic and therapeutical point of view, even if an adequate therapy permits in most cases to reach definite results. Therapy in inflammatory forms (odditis) must be first of all of medical type; only when these are changing into fibrosclerotic forms or are manifest in an acute way it is meet to proceed surgically on the sphincter. The action on the sphincter, either by means of endoscopy or surgery, is performed with caution in the forms of hypertonic dyskinesia (only when such forms are going on and have had a long duration, or even resistant to any pharmacological therapy) because of the high percentage of painful recurrences. The cutting of Oddi's sphincter is on the contrary the first therapeutical choice in the fibrosclerotic forms, with immediate success on the symptoms and the results in the long run are optimal.

[Evaluation of the functional state of the biliary tract by dynamic echocholecystography]. / Otsenka funktsional'nogo sostoianiia zhelchevyvodiashchei sistemy s pomoshch'iu dinamicheskoi ékhokholetsistografii.

The state of the biliary system (BS) was estimated by the size of gallbladder on a series of its ultrasonic sections in dynamics after cholecystokinetic breakfast. Noninvasiveness, convenience, simplicity, high informativity and absence of the diagnostic ultrasound effect on the organism permit using dynamic echocholecystography (DECG) repeatedly and over a long period of time preventing appearance of any complications. Studies carried out by means of DECG proceeding from the analysis of echocholystogram plots and quantitative parameters of the motor activity cycle of the bile cyst made it possible to characterize in detail the state of basic functional elements of BS relative to the healthy organism. DECG is promising to be used for an organism with pathology of the digestive system.

Asymmetric gallbladder contraction following cholecystokinin hepatobiliary imaging.

Three patients are presented with abnormal hepatobiliary images. A slow infusion of the terminal octapeptide of cholecystokinin caused asymmetric contraction in all three. Two of the patients displayed a bilobate appearance of the gallbladder. In one of the patients, there were typical changes associated with adenomyomatosis by other imaging modalities. The third patient showed good contraction of the fundus of the gallbladder but not of the proximal segment. In two of the patients, the global ejection fraction was considered to be normal. The asymmetrical contraction under the stimulus of cholecystokinin may be an important indicator of biliary dysfunction despite a normal ejection fraction.
