Predicting Factors of Common Bile Duct Diameter in South Khorasan; Addiction as a Public Dilemma

Introduction: Given the importance of identifying common bile duct diameter in diseases diagnoses and being different in different races, this paper aimed to investigate the relationship between the diameter of the common bile duct and demographic factors and drug addiction in patients who referred to the imaging department of Imam Reza hospital in Birjand during the year 1391-1392. Methods: This cross-sectional-analytical study was conducted on patients referred to the Imam Reza Hospital, Birjand University of Medical Sciences, during the year 91-1392. The study population consisted of patients with complaints other than the complaints associated with disorders of the liver and bile duct. Information about sex, drug use, BMI, age and duct diameter in proximal, middle and distal parts were recorded by the checklist. Data were analyzed using the SPSS software version 11.0 and the mean values, frequency of tests, Mann-Whitney and the Kruskal-Wallis tests. And values of p < 0.05 were considered significant. Results: A total of 315 subjects participated in the study. One hundred and sixty-two participants (51/4 percent) were female and the mean age of participants was 6/15±18/38. The mean diameter of the common bile duct in three proximal, middle and distal parts were determined as 4/2±1/5 mm, 4/2±6/5 mm and 4/2±9/5 mm. The results showed a significant relationship between bile duct diameter with age, gender, body mass index and addiction. (p < 05/0). Discussion: According to these results, in the case of dilated common bile duct in sonographic imaging and considering the age, gender, body mass index status and the addiction; findings need to be adapted to his clinical status.
