1. Biliary protein concentration was similar between the two groups.

2. Two of our 20 patients required further biliary drainage.

3. Does cholangiography establish the nature of a biliary stricture?

4. Placement of large bore plastic biliary stents was a good initial treatment for cholangitis or jaundice when present.

5. This increases biliary cholesterol content and favours nucleation of cholesterol monohydrate crystals.

5. Sentencedict.com is a sentence dictionary, on which you can find excellent sentences for a large number of words.

6. Patients with primary sclerosing cholangitis complicated by biliary tract calculi were more likely to be symptomatic at presentation than those without calculi.

7. A reduction of biliary phospholipids by dietary legumes was associated with an increased cholesterol saturation of bile.

8. This can progress to bile duct destruction, biliary cirrhosis, and sometimes cholangiocarcinoma.

9. Also, surgical morbidity related to biliary drainage remains high in these alcoholic and often debilitated patients.

10. The second had primary biliary cirrhosis and died from a variceal bleed while under review.

11. Despite these measures, biliary tract calculi recurred in all 12 patients after removal.

12. This could also explain the difference in biliary lipid secretion rate between the two groups.

13. These pioneering studies suggested that biliary secretion might be regulated by both vagal and non-vagal neural mechanisms.

14. This presumably reflects the fact that biliary stasis remains with a nidus of infection already present even after stones are removed.

15. Figure 4 shows the percentage of biliary cholesterol in the vesicular phase as a function of the amount of lecithin added.

16. Lasting success of extracorporeal shock wave lithotripsy for biliary stones will depend on advances in secondary prevention.

17. Despite these criteria, patients with biliary tract calculi have been included in several studies of primary sclerosing cholangitis.

18. Possibly a congenital abnormal connection was present between the cystic duct and the right biliary system.

19. Otherwise, clinical signs are absent except in the occasional case of intestinal or biliary obstruction.

20. These procedures carry the risk of introducing further infection into the biliary tree.

21. Liver biopsy showed that this patient already had secondary biliary cirrhosis.

22. However, this plan of management is advisable only if biliary drainage has been established.

23. The remaining amount of uric acid is excreted in the biliary, pancreatic, and gastrointestinal secretions through the gastrointestinal tract.

24. Recent findings have shown the importance of phospholipids in biliary pathophysiology.

25. Neuropeptide Y has also been isolated from the gastrointestinal tract with large concentrations found in the biliary tree.

26. Our data show that the addition of lecithin shifts biliary cholesterol from the vesicular to the non-vesicular phase.

27. Recent evidence suggests that phospholipids are of major importance in biliary pathophysiology.

28. In addition, the procedure usually takes longer and an endoscope of a greater diameter is used when biliary stenting is performed.

29. More recent studies have shown that hepatic denervation causes significant changes in the biliary lipid composition.

30. Cholangiography accurately locates the site of a stricture in the biliary tree and radiological features may suggest the presence of malignant disease.
