The histology of the common bile duct was studied in 45 patients with choledocholithiasis and/or papillitis and compared with a control group of ten cadavers without hepatic or biliary disease. Choledochitis was diagnosed in 44. Only one patient presented a histologically normal duct. The inflammatory process was characterized by proliferation of connective tissue and loss of elastic fibers, cellular infiltration of lymphocytes and polymorphonuclear leukocytes, and atrophic dilatation or hyperplasic glandular changes. Choledochitis was divided in two types: chronic and acute-chronic, and according to the intensity of the inflammatory process was also classified in slight, moderate or severe. No correlation was found between choledocholithiasis and/or papillitis and type and intensity of choledochitis.
对45例胆总管结石和/或乳头炎患者的胆总管组织学进行了研究，并与10例无肝脏或胆道疾病的尸体对照组进行了比较。44例被诊断为胆总管炎。只有1例患者的胆管在组织学上正常。炎症过程的特征是结缔组织增生和弹性纤维丧失、淋巴细胞和多形核白细胞的细胞浸润，以及萎缩性扩张或增生性腺体改变。胆总管炎分为两型：慢性型和急性-慢性型，并根据炎症过程的强度分为轻度、中度或重度。未发现胆总管结石和/或乳头炎与胆总管炎的类型和强度之间存在相关性。
