Optimization of tracheoesophageal fistula model established with T-shaped magnet system based on magnetic compression technique.

Background: The magnetic compression technique has been used to establish an animal model of tracheoesophageal fistula (TEF), but the commonly shaped magnets present limitations of poor homogeneity of TEF and poor model control. We designed a T-shaped magnet system to overcome these problems and verified its effectiveness animal experiments.

Aim: To investigate the effectiveness of a T-shaped magnet system for establishing a TEF model in beagle dogs.
