[Anatomo-pathological changes in the biliary system caused by povidone iodide. Experimental study].

In this report, the possible effects of povidone iodide (PVP-I) on the biliary system are studied in an experimental study using dogs. We used 20 dogs divided in two study groups. Light microscopy and electronic scanning microscopy (SEM) were used. We demonstrated that in the tied choledochus, intermittent washings with PVP-I caused a notable injury pattern on the biliary system.
