A compensatory coalition of the bowel with the bladder or urethra
is sometimes present, and in these cases the feces are voided by
the urinary passages. Huxham mentions the fusion of the rectum
and colon with the bladder, and similar instances are reported by
Dumas and Baillie. Zacutus Lusitanus describes an infant with an
imperforate membrane over its anus who voided feces through the
urethra for three months. After puncture of the membrane, the
discharge came through the natural passage and the child lived;
Morgagni mentions a somewhat similar case in a little girl living
in Bologna, and other modern instances have been reported. The
rectum may terminate in the vagina. Masters has seen a child who
lived nine days in whom the sigmoid flexure of the colon
terminated in the fundus of the bladder. Guinard pictures a case
in which there was communication between the rectum and the
bladder. In Figure 140 a represents the rectum; b the bladder; c
the point of communication; g shows the cellular tissue of the
scrotum.
There is a description of a girl of fourteen, otherwise well
constituted and healthy, who had neither external genital organs
nor anus. There was a plain dermal covering over the genital and
anal region.
