[The problem of fecal and urinary incontinence after extensive resection of the sacrum and 2d metamere].

Sacral resection was carried out in two patients presenting chordoma. Clinical and laboratory results are reported, with particular reference to preservation of anal and vesical continence. In the first case, double continence was virtually unaltered after unilateral resection of S2. In the second, continence was markedly perturbed by bilateral resection of S2.
