Benign neoplasms are rare events in the extrahepatic biliary ducts, and scanty literary references on the subject are available. Four cases of obstructive jaundice caused by benign tumours of the extrahepatic biliary ducts have been reviewed. Two of them have also displayed lithiasis of the gallbladder and common bile duct. In three cases histopathologic confirmation was obtained, in contrast to the remaining case in which only a gross pathologic presumptive diagnosis was possible. Three patients underwent surgical resection, and in one of them hepatojejunostomy was performed. The patient with a presumptive diagnosis of "inflammatory polyp" was not submitted to surgery, due to the special circumstances of the case. The undisturbed follow-up of the four cases attested to the worthiness of the surgical procedures.
良性肿瘤在肝外胆管中较为罕见，关于这一主题的文献资料也很少。本文回顾了4例由肝外胆管良性肿瘤引起的梗阻性黄疸病例。其中2例还伴有胆囊和胆总管结石。3例获得了组织病理学确诊，而其余1例仅进行了大体病理诊断。3例患者接受了手术切除，其中1例行肝空肠吻合术。由于该病例的特殊情况，1例初步诊断为“炎性息肉”的患者未接受手术。对这4例病例的随访结果证实了手术治疗的价值。
