Abstract:
Radical resection of gastrointestinal tumors based on the membrane anatomy theory has significantly reduced the postoperative recurrence rate and improved the surgical efficacy. However, the theory of membrane anatomy has not been widely adopted in radical surgery for esophageal cancer. Our study found that the esophagus also has a membranous anatomical structure. As a foregut organ, the esophagus also has a mesenteric structure, and there is also a fifth metastasis pathway within the esophageal mesentery for esophageal cancers. The leak and metastasis of cancer caused by destruction of the mesenteric integrity may be the fundamental reason for the high postoperative recurrence rate. Using the nano carbon and indocyanine green fluorescence tracing technique, we demonstrated the lymphatic drainage of the upper esophageal segment to the left gastric artery mesenteric lymph nodes. Therefore, in the radical resection of esophageal cancer, we used the membrane anatomy theory for guidance to completely remove the esophageal cancer, esophageal mesentery, left gastric artery and its mesentery, as well as all structures within the mesentery, preventing the spread of cancer cells through the blood vessels, lymphatic system, and mesentery, and improving the efficacy and prognosis. This article elaborates on the theoretical basis of the anatomical structure of the esophageal membrane, embryonic development, imaging, autopsy, and endoscopic observation of the structure, as well as the application effect of the esophageal membrane anatomical theory in esophageal cancer radical surgery. It elucidates the anatomical structure of the esophageal membrane and the lymphatic drainage characteristics of esophageal cancer, reveals the law of lymphatic metastasis in esophageal cancer, optimizes lymphatic dissection strategies, and improves the efficacy of esophageal cancer radical surgery.
