Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to study the law of intramural diffusion of low rectal cancer in different stages, and to explore the relationship between intramural diffusion of low rectal cancer and the distal resection margin during operation, so as to provide theoretical basis for clinicians to formulate accurate and individualized treatment plans, and help improve the prognosis and quality of life of patients.
