A retroperitoneal abscess with cutaneous fistula developed after stercoral fistula operation: a case report

Sparing treatment of chronic purulent sinusitis in children is an urgent problem of rhinology. Usage of preparations of donor (parental, of the same group) autoleukomass and blood plasm which possess all the components of humoral and cellular immunity proved highly effective against chronic purulent sinusitis in children. The drawback of this method is the necessity of regular lavage of the sinuses after insertion of the leukomass and heparinized plasm. The use of donor serum (parental, of the same group) also produced a good effect in purulent sinusitis. The serum advantage over the leukomass or plasm is that it can be left in the sinuses until the next procedure.
