[Choledochal lithiasis caused by non-absorbable sutures after biliary surgery].

The authors present two clinical observations of biliary calculi that developed upon the non-resorbable threads placed in the vicinity of the biliary pathways, or on the cystic stump, on the occasion of a previous intervention. A review is also presented, of the data in the literature and the process of development is discussed, of these calculi. The personal experience of the surgeon should be the decisive factor in making the right choice for such cases.
