Colonic anastomosis performed with a memory-shaped device.
BACKGROUND
The present study was prompted by our previous successful experience with the compression anastomosis clip (CAC) on animals followed by a study on 20 patients scheduled for colonic resection.


METHODS
Sixty patients with colonic cancer were assigned randomly to undergo an anastomosis either with the CAC or a stapler. To perform anastomosis with CAC, the 2 edges of the resected colon are aligned. Two 5-mm incisions are made close to the edges, through which (using a special applier) the CAC, after being cooled in ice water, is introduced in an open position. In response to the body temperature, the clip resumes its original (closed) position, thereby clamping the 2 bowel segments together. At the same time, a small scalpel incorporated in the applier makes a small incision through the clamped walls for the passage of gas and feces. The clip is detached from the applier to be left inside the intestine. The 2 5-mm incisions are sutured. The clip is expelled with the stool within 5 to 7 days, creating a perfect uniform compression anastomosis.


RESULTS
Neither group had anastomotic complications such as leakage or obstruction. All the other parameters were better in the study group than in the control patients.


CONCLUSIONS
The use of the CAC for colonic surgery is safe, simple, efficient, shortens operation time, and is almost what we call the "no-touch concept" in surgery and may decrease infection.
