Choledochal malformations (also known as choledochal cysts) may be characterised as an abnormal dilatation of the biliary tract, in the absence of any acute obstruction. Most appear to be of congenital origin probably related to distal bile duct stenosis, and almost 15% can now be detected antenatally. Excision and biliary reconstruction using a Roux loop as an open operation is still the standard to compare to. This article discusses recent advances in the understanding of their aetiology and classification together with the place of newer modalites of surgical treatment such as laparoscopic excision and biliary reconstruction. Although these are definitely feasible and safe, care should be taken before dispensing with standard open techniques which have minimal complications and proven long-term benefit.
胆总管畸形（也称为胆总管囊肿）可能表现为胆道的异常扩张，不存在任何急性梗阻。大多数似乎是先天性的，可能与远端胆管狭窄有关，现在近 15%的病例可以在产前检测到。切除和使用 Roux 袢进行胆肠重建仍然是作为标准术式来进行比较。本文讨论了对其病因和分类的最新认识，以及腹腔镜切除和胆肠重建等新的手术治疗方式的应用。虽然这些方法肯定是可行和安全的，但在摒弃具有最小并发症和长期受益的标准开放技术之前，应该谨慎行事。
