Surgical treatment of choledochal cyst.

A case of multiloculated choledochal cyst occurring in an 18-year-old girl is presented. The choledochus which contained multiple pigment stones was excised as the primary treatment and the patient remains well on two year follow-up. Ten additional cases of choledochal cyst treated in the past 20 years have been reviewed. It is concluded that excision of the choledochus is a safe and acceptable treatment of choledochal cyst in young low risk patients and that the alternative treatment of Roux-en-Y choledochocyst-jejunostomy gives satisfactory results.
