Background
In this study, given the importance of gastrointestinal anastomosis in surgical procedures, attempts have been made to compare the results of employing magnetic compression anastomosis and magnetic coils in intestinal anastomosis of rats.
Materials and Methods
This study was an experimental trial on 60 rats which had been randomly divided into two experiment (30) and control (30) groups. First, the rat intestine was cut off from a relatively fixed point and then magnet anastomosis was performed at the both ends of bowel in the control group and manual suture in the experiment group.  Anastomosis was then examined 10 days after the surgery for possible complications with a histological analysis of the indices of tissue repair.
Results
The mean time required for performing anastomosis of the rat intestine was 735 and 366 seconds for the control and experiment groups, respectively. Also, the laparotomy performed 10 days after the first operation did not show any significant difference between two groups in terms of surgical complications such as infiltration factor of inflammatory cell and fibroblast activity (P>0.05). The microscopic examination indicated that the tissue reaction in the anastomosis site was better in terms of tissue repair of neo-angiogenesis intestine and collagen deposition in the magnet group(P>0.05).  
Conclusion
Given the shorter duration of the anastomosis by magnets and more favorable histological results reported in the experiment group, as well as the lack of any significant difference in complications of the two techniques, magnetic compressive anastomosis can be used as a new technique for intestinal surgeries and pertaining anastomosis. Although, we recommend that study will be done with large sample size to obtain reliable results.
