[Experimental transplantation of the capsula fibrosa of patients with hepatic echinococcosis to white mice. Analysis of relapses after various surgical procedures].

Systematic histological investigations concerning the existence of protoscolices in the fibrotic capsula and in the liver parenchyma of operated patients were carried out by means of the immuno-fluorescence. A protoscolex in the fibrotic capsula was detectable histologically only once. The theory of Napalkov about the relapses of the disease by protoscolices invaded in the fibrotic capsula and surrounded tissue cannot be corroborated after the transplantation of fibrotic capsula in white mice before and after sterilisation by Scolicid and the other investigations. A method for sterilisation of the fibrotic cavity and the fibrotic capsula is presented. In that way difficult traumatising operations with high lethality like pericystectomy and resection of the liver are avoidable.
