[The defecation balloon proctogram in the study of idiopathic incontinence].

The authors report their findings in the study of idiopathic rectal incontinence using a defecatory balloon proctogram. The study provides a detailed anatomico-functional analysis of the sphincteric tract and, together with manometric and electromyographic studies, is useful in assessing the need for reconstructive surgery and for monitoring the results of ileoanal and coloanal anastomoses, sphincteric plastic surgery and posterior anal plastic surgery.
