Cholelithiasis in sickle cell disease: a cholecystographic and ultrasonographic evaluation in Nigerians.

A prospective study designed to establish the incidence of gallstones among 48 Nigerian homozygous sickle cell disease patients was made using oral cholecystography and grey-scale ultrasonography. The age range was 2 to 35 years with a mean of 16 years. The youngest patient with gallstones was a 51/2-year-old boy. Gallstones were demonstrated on cholecystosonography in 12 of 48 patients (25%). The incidence of cholelithiasis was 7.7% in children 10 years or younger and 31.4% in patients above this age. There was no correlation between the incidence of cholelithiasis and serum bilirubin on one hand and positive history of abdominal pain on the other. Screening of patients over 15 years for gallstones is suggested with a view to performing elective cholecystectomy in patients who subsequently become symptomatic.
