94. QUESTION ???
 The cause of high copper and iron content in the
pigment stone not clear
 Could it be dietary in origin ?

95. IS A DIETARY FACTOR RESPONSIBLE
..?
 Positive association

 Vegetables : ≥2 times per week (OR 0.09; 95 % CI 0.04-0.21)
 Fruits: > 3 times / week (OR 0.45; 95 % CI 0.20 to 0.99)
 Sugar: (OR 0.27; 95 % CI 0.07 to 0.95)
 Tea and coffee : less frequently by cases (2.5 vs. 2.9 cups/day; ANOVA
p<0.01).

BLACK PIGMENT GS
Black pigment
Complex compounds of Cu and Fe with bilirubin
(derived from Hb or its derivatives)
Nidus
Growth of cholesterol, calcium carbonate, apatite

103. ONGOING RESEARCH WORK
 Composition of bile….is south Indian bile non lithogenic?.....
Personal information: low cholesterol
 Crystallisation of GS based on bile composition
 Dissolution of synthesized GS by chemical agents

104. SUMMARISING…. GS

105. SUMMARY…
 Gallstones from south India are distinctive
 Morphology
 Chemical composition
 Majority are pigment or mixed
 Bile is non lithogenic (Ms Ramya, personal communication)
 GB cancer incidence is low
