ARTICLE HIGHLIGHTS
Research background

Magnetic compression anastomosis, as a new type of anastomosis, mainly includes esophageal anastomosis, gastrointestinal anastomosis and intestinal anastomosis in the study and clinical application of digestive tract. At present, there are more and more researches on magnetic compression anastomosis (MCA), but there is no relevant research report on magnetic force and anastomosis healing.

Research motivation

At present, there are few reports on the relationship between MCA and optimal magnetic force, and the evaluation criteria of optimal magnetic force are inconsistent. We think that such studies are not enough.

Research objectives

To investigate the influence of different magnetic magnets on the anastomosis formed by MCA of digestive tract.

Research methods

Colonic MCA was performed on two groups of rats using two sets of magnets of the same size but different magnetic forces. The anastomotic specimens were collected 4 wk after operation to evaluate the formation of the anastomosis in the two groups.

Research results

There was no significant difference in operation time, bursting pressure and anastomotic diameter between the two groups. The discharge time of the strong magnet group was slightly longer than that of the common magnet group, but the difference was not statistically significant. The anastomosis of the two groups of specimens healed well, the continuity of the mucosa was good, and there was no difference in healing.

Research conclusions

The results indicate that there is no significant difference in the formation of the anastomosis between the magnets with different magnetic forces used in this experiment.

Research perspectives

Although this study seems to have a negative result, it has important significance in the basic research of MCA.
