OBJECTIVE	To evaluate the clinical efficacy and safety of tissue-selecting therapy ( TST ) in treatment of mixed hemorrhoids .
METHODS	A single-blind randomized study was carried out .
METHODS	A total of 120 patients with mixed hemorrhoids from January to December 2012 were prospectively enrolled in the study and equally divided into two groups , TST group and procedure for prolapse and hemorrhoids ( PPH ) group .
METHODS	Surgical data , efficacy and postoperative complications were compared between the two groups .
RESULTS	As compared to PPH group , patients in TST group had shorter operation time [ ( 15.95.18 ) min vs. ( 22.67.1 ) min , P < 0.05 ] , lower scores of rectal urgency ( 0.50.2 vs. 1.51.4 , P < 0.05 ) , and shorter hospital stay [ ( 11.23.7 ) d vs. ( 14.83.7 ) d , P < 0.05 ] .
RESULTS	No anastomotic stricture case was found in TST group , while 11 cases ( 18.3 % ) developed anastomotic stricture in PPH group .
RESULTS	There were no significant differences in effective rate and pain score of first defecation between the two groups .
CONCLUSIONS	TST is reliable and safe for mixed hemorrhoids with the advantage of simple , rapid recovery and less complications .
