Methods: 59 patients with low rectal cancer were randomly divided into 2 groups: the control group received the anastomosis by anastomat and the study group received the anastomosis by hand.

Method 33 cases of operative failures in posterior Urethral injury and interlocking sound urethroplasty had been performed epicystostomy for surgery,and then scar excision & urethral anastomosis were performed without cystidolaparotomy after three months.

OBJECTIVE Compare the therapeutic effects of anastomosis stapler and dixon for rectal carcinoma.
