BACKGROUND/AIMS: The purpose of the study was to see the effect of age, sex, body mass index, previous cholecystectomy, hepatomegaly and fasting status on the common bile duct diameter.
A series of 463 patients, 283 females and 180 males, with no hepatobiliary or pancreatic pathology were included in this study, the mean age was 45 +/- 16 years. Their age, sex, weight, height, fasting status and previous cholecystectomy was assessed and recorded by a physician prior to ultrasound examination. All patients were examined by real-time ultrasound to see if there was any pathology in the hepatobiliary and pancreatic area. Those with history of common bile duct exploration, endoscopic sphincterotomy or with previous history of cholecystectomy of less than 6 months and patients with common bile duct pathology were excluded from the study. The midportion of the common bile duct was taken as a fixed measurement for all patients and the size of the liver was also recorded. Analysis of variance as part of SPSS statistical package was used where common bile duct was considered a dependent variable, while sex, fasting status, hepatomegaly and previous cholecystectomy were considered to be independent variables, age and sex were considered as co-variants.
The factors found to be significantly affecting the diameter of the common bile duct (P<0.05) were age, previous cholecystectomy and body mass index.
If the CBD dilatation can not be explained by age, previous cholecystectomy and BMI, a pathology causing obstruction should be ruled out.
背景/目的：本研究旨在观察年龄、性别、体重指数、既往胆囊切除术、肝肿大和禁食状态对胆总管直径的影响。
本研究纳入了463例无肝胆或胰腺病变的患者，其中女性283例，男性180例，平均年龄为45±16岁。在超声检查前，由医生评估并记录他们的年龄、性别、体重、身高、禁食状态和既往胆囊切除术情况。所有患者均接受实时超声检查，以查看肝胆和胰腺区域是否存在任何病变。有胆总管探查史、内镜括约肌切开术史或既往胆囊切除术史少于6个月的患者以及有胆总管病变的患者被排除在研究之外。所有患者均以胆总管中部作为固定测量部位，并记录肝脏大小。使用SPSS统计软件包中的方差分析，将胆总管视为因变量，而将性别、禁食状态、肝肿大和既往胆囊切除术视为自变量，年龄和性别视为协变量。
发现对胆总管直径有显著影响的因素（P<0.05）为年龄、既往胆囊切除术和体重指数。
如果胆总管扩张不能用年龄、既往胆囊切除术和体重指数来解释，则应排除导致梗阻的病变。
