We studied common duct (CD) diameter using real time ultrasound in 551 patients. The patients were divided into two groups: those referred for evaluation of the biliary tree [biliary-referred group (BRG)], and those referred for a problem unrelated to potential biliary tree pathology [non-biliary-referred group (NBRG)]. Potentially obstructed CDs were excluded from analysis. The CD diameter in the NBRG patients was found to increase after cholecystectomy (p less than 0.0003), but not in patients in this group with intact gallbladders and cholelithiasis. Dilation was observed in the BRG patients with either cholelithiasis (p less than 6 x 10(-7)) or cholecystectomy (p less than 4 x 10(-10)) compared to patients with intact gallbladders without cholelithiasis. To our knowledge, the former phenomenon has not been described in the literature. Our NBRG data suggest that the normal CD diameter should be set at 5 mm and 8 mm, respectively, for patients with intact gallbladders and patients post-cholecystectomy. No correlation was found between duct size and sex, age, or weight.
我们使用实时超声对551例患者的胆总管（CD）直径进行了研究。患者被分为两组：因胆道系统评估而转诊的患者[胆道转诊组（BRG）]，以及因与潜在胆道系统病变无关的问题而转诊的患者[非胆道转诊组（NBRG）]。分析中排除了可能存在梗阻的胆总管。发现NBRG组患者在胆囊切除术后胆总管直径增加（p<0.0003），但该组中胆囊完整且有胆结石的患者则不然。与胆囊完整且无胆结石的患者相比，BRG组中有胆结石（p<6×10⁻⁷）或胆囊切除术（p<4×10⁻¹⁰）的患者观察到胆总管扩张。据我们所知，前一种现象在文献中尚未有描述。我们的NBRG数据表明，对于胆囊完整的患者和胆囊切除术后的患者，正常胆总管直径应分别设定为5毫米和8毫米。未发现胆管大小与性别、年龄或体重之间存在相关性。
