NiTi shape memory compression anastomosis clip in small- and large-bowel anastomoses: first experience.
The aim of the study was to present a clinical use of compression anastomosis clip (CAC) implants made of shape memory materials--nickel titanium alloys (NiTi). The concept involved in the use of CAC was to compress 2 bowel walls together, cause necrosis, and detach the CAC from the tissue to be expelled with the stool. The CAC is a double-ring elliptical device with a diameter of 30 mm. The device has the ability to recover its original closed shape when it senses a change in ambient temperature. In all, 20 anastomoses using CACs were performed: 6 of the small with the large bowel and 14 between the small bowel and small bowel. Two patients experienced complications. Although the anastomosis is not difficult to perform, the rules on how to apply the CAC must be well known. Because only a small number of anastomoses have been performed by us to date, this procedure requires further study.
