[Compression anastomosis ring: a novel technique for colorectal anastomosis].
OBJECTIVE
To evaluate the safety and efficacy of a novel nickel-titanium memory alloy compression anastomosis ring(CAR27) for colorectal anastomosis.


METHODS
One sigmoid cancer patient undergone lower anterior resection(LAR) received colorectal anastomosis with CAR27 on November 12, 2009. The following parameters were recorded during 4 weeks postoperative follow-up:colorectal anastomotic complication,first post-operation flatus and bowel movement, extrusion of ring device.


RESULTS
The total operation time was 42 minutes, including 11 minutes for colorectal anastomosis. The patient had flatus at the first day and began feeding at the second day postoperatively. The ring was expelled with stool at the 10th day postoperatively. Patient didn't have anastomotic complications such as leakage or obstruction during 1 month postoperative follow-up.


CONCLUSIONS
This case study primarily indicates CAR27 is safe and feasible for colorectal anastomosis.
