Gall bladder contractility in children with beta-thalassaemia

We studied gall bladder contractility in 61 children with beta-thalassaemia who were asymptomatic for gall bladder disease and 51 sex- and age-matched controls in Cairo, Egypt, using real-time ultrasonography. Multiple gall bladder stones were present in 18.0% of thalassaemia patients and sludge in 6.6%. There were statistically significant differences between thalassaemia patients and controls in gall bladder fasting volume, residual volume, emptying time and contraction index. There was significant positive correlation between fasting and residual volumes and age, weight and height, and between fasting volume and body mass index and serum ferritin level. Contraction index was negatively correlated with serum total bilirubin. Impaired gall bladder motility was evident in patients with beta-thalassaemia and it may be related to disease duration, serum ferritin and total serum bilirubin level.
