rectorectal

Etymology
=

Adjective

 * 1)  Relating to two parts of the rectum, as, for example, in a rectorectal intussusception, in which the two parts telescope together.

Usage notes
Do not confuse ("among parts of the rectum") with  ("behind the rectum"), nor  ("between the rectum and vagina") with  ("behind the vagina"). Intussusceptions (which involve telescoping movement) may be rectorectal; fistulas (which are passages between spaces) may be rectovaginal; hematomas and hemorrhages (which fill up a space) may be retrorectal (i.e., ); tumors inside the may be retrovaginal. Mentions of *retrovaginal fistulas are virtually always for.
