Nickel-titanium memory-shape alloy compression anastomosis clip for ileocolon anastomosis

Objective Nickel-titanium memory-shape alloy compression anastomosis clip(CAC) has been successfully used in small bowel anastomosis and colonic anastomosis.This study was to evaluate the safety and efficacy of CAC in ileocolon anastomosis.Methods Twenty patients with ileocecal junction obstruction induced by radiation enterocolitis were assigned randomly to a CAC and a control group to undergo anastomosis with either a CAC or a stapler.We compared the two groups in anastomotic complications,first post-operation flatus and bowel movement,and expelling of the clip.Results Such anastomotic complications as infection,leakage and obstruction were found in neither group.The clips were expelled with the stool within 8-16 days.The two groups showed similar results in bowel function recovery.Conclusion Nickel-titanium memory-shape alloy CAC is a safe and reliable device for ileocolon anastomosis.
