Abstract:
This study aims to evaluate the relation between the cystocholedochal angle (SCA) and choledocholithiasis. The data of 3.350 patients were reviewed retrospectively and a total of 628 patients who met the criteria were included in the study. The patients included in the study were divided into three groups as patients with choledocholithiasis (Group I), patients with only cholelithiasis (Group II), and patients without gallstones as control group (Group III). Measurements of SCA, cystic, bile, and common hepatic ducts (CHDs) were made on magnetic resonance cholangiopancreatography (MRCP) images. Laboratory findings and demographic characteristics of the patients were also recorded. Of the patients included in the study 64.2% were female, 35.8% were male, and their age ranged from 18 to 93 (mean 53.37 ± 18.87 years). While the mean SCA values of all patient groups were 35.44° ± 10.44°, the mean length of cystic, bile and CHDs were 28.91 ± 9.30, 40.28 ± 12.91, 27.09 ± 9.68 mm respectively. All measurements were higher in Group I in comparison to other groups, whereas all measurements of Group II were higher than those of Group III (p < 0.001). Statistical analysis suggests that a SCA of 33.5° and above is an important criterion for diagnosis of choledocholithiasis. Increase of SCA raises the likelihood of choledocholithiasis, as it facilitates the passage of stones from gallbladder into the bile ducts. This is the first study to compare SCA in patients with choledocholithiasis and those with only cholelithiasis. Therefore, we think that this study is important and will be a guide for clinical evaluation.
摘要:
本研究旨在评估膀胱胆总管角(SCA)与胆总管结石之间的关系。对3.350例患者的数据进行了回顾性分析,总共628例符合标准的患者被纳入研究。将纳入研究的患者分为三组胆总管结石患者(第一组),只有胆石症的患者(第二组),无胆结石患者作为对照组(组III)。SCA的测量,囊性的,胆汁,在磁共振胰胆管成像(MRCP)图像上制作了总肝管(CHD)。还记录了患者的实验室检查结果和人口统计学特征。纳入研究的患者中,64.2%为女性,35.8%为男性,年龄18~93岁(平均53.37±18.87岁)。而所有患者组的平均SCA值为35.44°±10.44°,囊性的平均长度,胆汁和冠心病分别为28.91±9.30、40.28±12.91、27.09±9.68mm。与其他组相比,第一组的所有测量值均较高,而II组的所有测量值均高于III组(p<0.001)。统计分析表明,33.5°及以上的SCA是诊断胆总管结石的重要标准。SCA的增加增加了胆总管结石的可能性,因为它有助于结石从胆囊进入胆管。这是第一项比较胆总管结石患者和仅胆石症患者SCA的研究。因此,我们认为这项研究很重要,将为临床评估提供指导。
