Especially, bilirubin stone ´is .found frequently in Korea and the formation of the bilirubin `-stones is much corelated to the infection or inflammation.
j This study is a review and analysis of 68 cases of the bile culture in the biliary. tract disease that were admitted and treated at Ewha Woman University Ho-
;j spital from June 1980 t% June 1983.
The results are as follows
1) The age group of the highest incidence was 60 decades ( 29.4/o) and 40 decades (25 % ) in next.
2) There was 22 male 46 female andmale to female ratio was 1:2.
3) In 57 cases of calculus biliary tract disease, the location of stone were 29 cases (42.6 %) in gall bladder, 11 cases (16.2%) in common bile duct ; and 11 cases (16.2 %) in gall bladder and common bile duct. No stone was 11 cases ( 16.2%).
4) In 68 cases of the biliary tract disease, 47 cases (69.1 1/o ) were positive culture and in 57 stone cases of ´biliary tract disease, 44 cases (77.2%) were positive culture.
5) In relation to postop. Dx. and bile culture, the positive culture in G.B. bile was 58.3 "/o and positive culture in CBD bile was 1001/10 in acute cholecystitis with stone cases, where as, the positive G.B. bile culture was 50 yo and the positive CBD bile was 59.3% in chronic cholecystitis with stone cases.
6) In relation to location of stones and culture, the positive, the positive culture in G.B. stone was 55.2O/o in G.B. bile and 57.1 % in GBD bile, where as, in CB D stone cases, the positive bile culture was 63.6% in G.B. bile and 100% bile.
!7) The isolated organism was E. coli (12 cases), klebsiella (11 cases in G.B bile and 9 cases in CBD bile) and Citrobacter (6 cases in G.B. bile and 3 cases in CBD bile), etc.
8) In sensitivity test of microorganisms to the antibiotics, organisms were susceptible to the general antibiotics.
