What is cbd in abdominal ultrasound

In order to compare the diameter across the five age groups, and test the null hypothesis that the groups have the same common bile duct diameters, we applied the Analysis of Variance (ANOVA). The difference was found to be statistically significant (p = 0.05).

Setting and Design: Cross-sectional hospital-based study conducted at Mahatma Gandhi Medical College and Hospital, Jaipur, India.

The mean common bile duct diameters of proximal and distal parts were 4.0 mm (SD 1.02 mm) and 4.2 mm (SD 1.01 mm), respectively. A strong correlation was found between proximal and distal part of CBD due to constant diameter. Similar correlation has been reported by Adibi and Givechian [19] and Niederau et al., [9].

Results

In our study, the common bile duct did not have any significant correlation with the anthropometric measurements. Niederau et al., [9] reported no correlation with height and body surface area; although the common bile duct showed correlation with weight, albeit a poor one (r = 0.11). Admassie [11] found positive correlation of common bile duct diameter with weight, however no such relation was found with height. However, Reinus et al., [15] in his study observed no such correlation with weight.

It is an established fact that variations exist in the anthropometric features of various populations, races and regions [4]. Studies have suggested correlation between different kinds of body builds and diseases. However, despite technological advancements, the association of anthropometric measurements with the diameters of common bile duct has remained controversial.

In order to assess the association between common bile duct diameter and anthropometric measurements, both of which were continuous variables, correlation was used.

The size of the common bile duct is a predictor of biliary obstruction and it’s measurement is therefore an important component in the evaluation of the biliary system. Availability of normal measurements of the common bile duct would help to distinguish obstructive from non-obstructive causes of jaundice.
