ACKGROUND Gallstone disease is a common gastrointestinal problem in day-to-day practice. The old concept that a typical gallstone sufferer is fat, fertile, flatulent female of 50. This is partially true as the disease has been found in women soon after their first delivery who are thin and underweight and in males also. Conditions that favour the formation of cholesterol gallstones are super saturation of bile with cholesterol, kinetically favourable nucleation and presence of cholesterol crystals in the gallbladder long enough to agglomerate into a stone. Recent studies have defined the role of trace elements (Fe, Ca, Zn and Cu) and defective pH in the formation of gallstones. The aim of the study is to determine the association of iron deficiency in super saturation of bile. This cross-sectional study of 50 patients was conducted over a period of 12 months in the Department of General Surgery, Kilpauk Medical College, Chennai, India. Biliary cholesterol and serum cholesterol were compared in iron deficient and non-iron deficient patients having gallstones. A low serum iron level is a factor in bile super saturation with respect to cholesterol leading to gallstone formation. MATERIALS AND METHODS This study was conducted over a period of 12 months in the Department of General Surgery, Kilpauk Medical College, Chennai, India. 50 patients suffering from cholelithiasis confirmed by USG were divided into two groups based on serum iron values. Group A consists of patients with normal serum iron (non-anaemic) and Group B of patients with less than normal serum iron (anaemic). RESULTS Serum total cholesterol of the patients of cholelithiasis was not different among groups categorised based on serum iron levels. There were no significant variations in the serum cholesterol contents of both the groups. Also, there was no significant variation of the above parameter in the male and female patients. CONCLUSION Though, it is difficult to draw a causal relation between low iron levels and cholelithiasis with this study design alone in future prospective trials could aim at better defining if such causal relationship exists.
