Study variables Dependent variable; diameter of the common bile duct, independent variables; include Sociodemographic data age, sex, place of residence and anthropometric characteristics height, weight, and body mass index. Results: A total of subjects participated in the study. Respiratory variation of extrahepatic bile duct diameter during ultrasonography. Brent A. The overall measurement was 4. A report of cases.


Aging, overweight and previous cholecystectomy are associated with the dilatation Laks , Daradkeh et al. Ultrasonographic measurement of normal common bile duct diameter and its correlation with age, sex and anthropometry. Data were analyzed using the SPSS software version In the IHBD dilatation group, the severity of dilatation was also associated with the presence of a definitive causative lesion OR 5. However, no such correlation was reported in a study by Brogna et al. Keeping other variables constant, one year increase in the age of respondents increases the diameter by the factor of 0. Ultrasonography is an accurate, safe, non-invasive and inexpensive imaging modality, which is highly sensitive and specific for the detection of many biliary tree diseases [ 1 ].


Cholelithiasis was present in 8 percent of the emergency patients, second to acute appendicitis. A bile duct stricture is defined as a stenosis of the lumen that is judged sufficient to account for abnormal blood chemistry and to impair bile flow Figs 20, We prospectively collected data on patients aged 20 years or older who underwent abdominal sonography. Thomas H. More attention should be paid to patients with PD dilation or weight loss to prevent misdiagnosis of malignant CBD dilation.

This constant relationship helps to demonstrate CBD and differentiate it from the portal vein and hepatic artery by using ultrasonography [ 1 , 4 ]. Fig 1. Although imaging techniques have been developed significantly in recent years, but there are still many different opinions the scientific community on the effect of age, weight, sex, and Cholecystectomy on common bile duct diameter [9,10]. The common bile duct was identified through its association with the portal vein in the long axis of the gallbladder. Among adult subjects, Bruneton et al.

However, it's difficult to perform and more challenging in dog as the average ductal length is 2 -3 mm; while in human it is 6 -7 mm [4, 5]. Cooperberg PL. The aim of the present study was to analyze the value of the degree of common bile duct dilatation in differential diagnosis of extrahepatic cholestasis. Ultrasonographic measurement of normal common bile duct diameter and its correlation with age, sex and anthropometry. The upper limit of normal is 6 mm, but this is considered in relation to the patient's age [12, 13].

Therefore it is common practice to use the term common duct CD as a term conflating the common hepatic and common bile ducts. Periampullary diverticula and choledocholithiasis were the most common findings; of 32 patients with normal serum liver enzymes, one periampullary diverticulum and one CBD stone were found, respectively. Copy link Link copied. After exclusion, 44 patients were analyzed retrospectively. The mean diameter of the CBD was 3. The current study examined the relationship between age, CBD size, and the diagnostic probability of choledocolithiasis. Mar

Mean and standard deviation of common bile duct diameter by age group. English version of data collection check list. Gastroenterologists increasingly find themselves in the un-enviable position of having to choose the optimal radiographic test to visualize the biliary tree and the liver. The Levene's Test of homogeneity of Variances, Kolmogorov-Smirnov and Shapiro-Wilk test of normality, multicollinearity diagnosis, and other assumptions were checked before doing any statistical analysis and were fulfilled and the distribution of the data were also assessed using histogram Figs 3 and 4. These results have been confirmed by other studies [9, 11, 16,19]. Alan Coss Robert Enns.

We conducted this study to obtain data on sonographically measured diameters of common bile duct among Rajasthani population in order to determine the range of normal diameters for common bile duct among this population and to determine its association with age, sex, physical measurements like height, weight, chest circumference, circumference at the transpyloric plane, circumference at the umbilicus and circumference at the hip. In patients with clinically suspected biliary stone disease, without initial sonographic documentation of choledocholithiasis, endoscopic ultrasound or magnetic resonance cholangiopancreatography is the next logical imaging step. Jukka Karvonen. Sonography of the common bile duct: value of the right anterior oblique view. Studies to determine the range of normality for the common bile duct diameter would help in defining the upper limit in assessment of patients suffering from obstructive jaundice. The diameter was found to increase progressively from 3. Louis: Mosby, —
