[Diagnosis and treatment of choledochus cysts (author's transl)]

Two cases we observed initiated a survey of the literature concerning the surgical management of choledochus cysts. We compared long-term results with regard to postoperative complications, rates of necessity of reoperation and operative mortality in 316 reported cases. Resection of the choledochus cyst and a subsequent biliodigestive anastomosis performed as choledocho-jejunostomy (as outlined by Roux) is the therapy of choice in this rare disease, since it gives the best long-term results.
