Clinical observations on the treatment of prolapsing hemorrhoids with tissue selecting therapy.

Aim: To compare the effects and postoperative complications between tissue selecting therapy stapler (TST) and Milligan-Morgan hemorrhoidectomy (M-M).

Methods: Four hundred and eighty patients with severe prolapsing hemorrhoids, who were admitted to the Shenyang Coloproctology Hospital between 2009 and 2012, were randomly divided into observation (n=240) and control (n=240) groups. Hemorrhoidectomies were performed with TST in the observation group and with the M-M technique in the control group.
