Endoscopic treatment of massive rectal bleeding following prostate needle biopsy.

We describe two cases of massive rectal bleeding following needle biopsy of the prostate. In each case, colonoscopic evaluation revealed bleeding from the biopsy site. Bleeding was controlled with the placement of a single band in one case, and with epinephrine injection in the other. Endoscopic evaluation of patients presenting with severe rectal bleeding following needle biopsy of the prostate may allow immediate therapy.
