| Résumé: | Background: Despite ultrasound safety, affordability and its widespread use in evaluation of the
diseases of biliary tree, paucity of literature on the sonographic measurements of the size of the
normal adult common bile duct (CBD) in this environment exists. Objectives: To determine the
normal adult diameter of the CBD in this environment using ultrasonography. Methods: This was a
cross-sectional prospective study carried out at the University of Maiduguri Teaching Hospital
between January to June, 2011. Results: There were 224(56%) females and 176(44%) males aged
between 18 and 87 years (Mean±SD, 36.88±16.97 years). The mean AP and transverse CBD diameters
(±SD) were 3.68±0.82mm and 3.89±0.86mm, respectively. The average mean for the two
measurements (± SD) was 3.78±0.84mm (range = 2.0 – 6.0 mm). The mean transverse diameter was
slightly greater than AP diameter (p = 0.0004).The CBD diameter was strongly correlated with age (r =
0.798; p = 0.000; r2 = 0.629). The least squares regression slope of 0.039mm±0.001 (mean±SD) was
obtained suggesting 0.039mm±0.001 increase in the CBD diameter per year. There was significant
correlation between the CBD diameter with weight (r = 0.504; p = 0.000) and BMI (r = 0.454; p = 0.000).
No significant difference between the mean CBD diameter in males and females (p= 0.084) was
observed. Conclusion: The mean and range of CBD size in normal adult population were determined
and significantly correlated with age, weight, and BMI. |
