rectovaginal fistula 

A rectovaginal fistula is a medical condition where there is a fistula or abnormal connection between the rectum and the vagina. Rectovaginal fistula may be extremely debilitating. If the opening between the rectum and vagina is wide it will allow both flatulence and feces to escape through the vagina, leading to fecal incontinence. There is an association with recurrent urinary and vaginal infections.

Funniest disease ever!!!

Stu: "Well Mike, what you got yourself there, is a classic case of the ol' rectovaginal fistula".
