The usefulness of compression anastomotic clips (CAC) for small bowel anastomosis in animals was evaluated. Implants made of nickel-titanium alloy (NiTi) in the form of elliptical double-coil springs with one-way and two-way shape memory were applied. The studied animals were subjected to jejunal resection and side-to-side bowel anastomosis with the use of CACs. The experiment was conducted on 10 pigs divided into three groups. The speed and ease of the surgical procedure, implant excretion time and leak tightness were evaluated by macroscopic observations and X-ray examinations. Tissue samples from the anastomotic site were subjected to histopathological analysis. The applied method was characterised by tight connections between fused tissue, the absence of complications and ease of use. The results of the study indicate that shape memory NiTi clips are a promising tool in veterinary gastrointestinal surgery.
