To determine the average value of the diameter of the common bile duct by age group in adult patients without bile duct pathology.
A cross-sectional, observational, descriptive and prospective study in adults without bile duct pathology who underwent abdominal ultrasound. The internal diameter of the common bile duct was measured after questioning. In the descriptive analysis, absolute frequencies, percentages, mean and standard deviation were used in the inferential Student's t test and Pearson's correlation.
608 patients without bile duct pathology were included, the mean diameter of the common bile duct was 4.04 ± 1.11 mm; with a minimum of 1.9 mm and a maximum of 8.8 mm. The mean for the population under 30 years was 3.8 ± 0.87, for the 30-39 years group it was 4.27 ± 0.89, for the 40-49 years group it was 4.39 ± 0.83, for the 50-59 years 4.86 ± 1, for the 60-69 years group it was 5.4 ± 0.95, and for those over 70 years it was 6.9 ± 0.8.
The diameter of the common bile duct in adult patients without biliary pathology is greater at older age.
确定无胆管疾病的成年患者按年龄组划分的胆总管直径平均值。
这是一项横断面、观察性、描述性和前瞻性研究，纳入了接受腹部超声检查且无胆管疾病的成年患者。在询问后测量胆总管的内径。在描述性分析中，使用绝对频率、百分比、均值和标准差进行推断性学生 t 检验和 Pearson 相关性分析。
共纳入 608 例无胆管疾病患者，胆总管直径的平均值为 4.04 ± 1.11mm；最小值为 1.9mm，最大值为 8.8mm。30 岁以下人群的平均值为 3.8 ± 0.87，30-39 岁组为 4.27 ± 0.89，40-49 岁组为 4.39 ± 0.83，50-59 岁组为 4.86 ± 1，60-69 岁组为 5.4 ± 0.95，70 岁以上组为 6.9 ± 0.8。
无胆道疾病的成年患者胆总管直径随年龄增长而增大。
