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.
BACKGROUND: Although biliary dyskinesia is treated commonly with cholecystectomy, the supporting literature is limited. A review and meta-analysis of the literature were performed to assess the efficacy of surgical therapy for biliary dyskinesia. MATERIALS AND METHODS: A MEDLINE search for the period 1965 to 2003, using the search strings "biliary," "acalculous," "dyskinesia," "cholecystitis," "cholecystectomy," and "therapy" returned 187 articles. Inclusion criteria required a study design that placed patients with biliary dyskinesia into one of two treatment groups, cholecystectomy or nonoperative therapy, and a follow-up assessment of symptomatic improvement. RESULTS: Five studies met the inclusion criteria, representing a total of 274 patients. Surgical therapy resulted in 98% symptomatic relief compared to 32% with nonoperative management (P<0.0001). Patients undergoing surgical therapy for biliary dyskinesia were 2.79 times more likely to have symptomatic relief versus nonoperative therapy (95% confidence interval, 2.05-3.79). CONCLUSION: Based on this meta-analysis, cholecystectomy for biliary dyskinesia is an effective therapy and offers significant symptomatic relief over nonoperative therapy.
AIM: The aim of the present study was to develop a new pharmacologic method during hepatobiliary scintigraphy by which patients with functional and organic forms of gallbladder (GB) dysfunction can be differentiated. METHODS: Quantitative hepatobiliary scintigraphy (QHBS) was performed on 31 patients with impaired GB motility selected by cerulein-augmented ultrasonography. Nineteen patients had acalculous biliary pain (ABP) and suspected GB dyskinesia, 6 patients had celiac disease, and 6 patients had type II diabetes mellitus. Sixty minutes after the isotope administration, 1 ng/bwkg/min cerulein (CCK10) was infused for 10 minutes, and then from the 90th minute, an equivalent dose of CCK10 was infused in the presence of 0.5 mg sublingual glyceryl trinitrate (GTN) in 12 or placebo in 7 consecutive patients. The GB ejection fraction (GBEF) was calculated repeatedly in time periods from 60 to 90 and from 90 to 120 minutes. RESULTS: In the majority of patients with ABP and suspected GB dyskinesia, CCK10 and GTN coadministration normalized the previously impaired GB-emptying. When the cumulative results of all 12 patients were calculated, we demonstrated significant differences (P=0.003) in the GBEF between the first (CCK10) versus the second (CCK10 plus GTN) stimuli: 19+/-11% versus 40+/-17%, respectively. In contrast, in 12 patients with celiac sprue and diabetes mellitus, no differences in the GBEF were detected when the first (CCK10 alone) versus the second (CCK10 plus GTN) stimuli was compared: 21+/-10% versus 22+/-13%, respectively. Finally, placebo and CCK10 coadministration in 7 consecutive patients with ABP and suspected GB dyskinesia did not influence the GBEF as compared with CCK10 alone: 13+/-9% versus 15+/-10%, respectively. CONCLUSION: GTN and CCK10 coadministration induces a significant improvement of the GBEF in patients with GB dyskinesia. The application of this new pharmacologic test during QHBS permitted the noninvasive separation of those patients with secondary impaired GB-emptying as a result of GB dyskinesia from those with primary forms of GB hypokinesia.
