ObjectiveTo investigate the progress and controversy of membrane anatomy theory in laparoscopic surgery for mid-low rectal cancer. MethodThe literature related to membrane anatomy theory in recent years was reviewed and summarized. ResultsThe membrane anatomy theory not only improved the effect of total mesorectal excision, ensured the integrity of the mesorectum, more standardized the operation and principles of rectal cancer surgery, but also provided the operator with a broad vision and clear anatomical hierarchy. The theory of membrane anatomy had important clinical significance for tumor radical resection, organ resection and functional protection. However, this theory had not been unified, and the establishment of membrane plane and the choice of surgical plane were still needed to be studied and explored. ConclusionAt present, scholars at home still regard the theory of membrane anatomy as the theoretical support and reference basis for the endoscopic treatment of mid-low rectal cancer, which can provide surgeons with new treatment prospects and research direction, and improve the survival expectancy and quality of life of patients with intestinal cancer in the future.
