[Laparoscopic aspect and clinical relevance of cholangiofibromas].

In a current series of 1160 laparoscopies in 38 cases (3.2%) we found cholangiofibromas. The picture of single, sporadic and multiple cholangiofibromas as well as cholangiofibromatosis is both described and documented by laparoscopic photography. Clinically it seems remarkable that only patients with alcohol- or drug-induced liver injury showed such alterations. The prevalence of cholangiofibromas in toxic liver damage suggests that we are here not dealing with embryonal aberrations (hamartomas) but apparently with cellular inductive phenomena.
