Objective：To investigate the effectiveness of sero-muscular flap-covering anstomosis for acute obstructive left-colon carcinoma.
Methods：Clincal data of 57 patients with acute obstructive left-colon carcinoma treated in our department from 2000—2009 were retrospectively analyzed. All of them were treated with one-stage  resection and anastomosis with sero-muscular flap-covering.
Results：Among the 57 cases, no postoperative intestinal fistula,abdominal infection or death occurred,5 were complicanted with wound infection only.
Conclusions：One-stage  resection and anastomosis with sero-muscular flap-covering in patients with acute obstructive left-colon carcinoma is safe and feasible,and can avoid the problems of secondary operation  and colostomy. This anastomotic procedure has proved effective in preventing anastomotic fistula after primary resection of acute obstructive carcinoma of left colon.
