Diagnosis and Minimally Invasive Endoscopic Treatment of Early Esophageal Cancer and Precancerous Lesions
Abstract
Esophageal cancer is a common malignancy of digestive tract, and its prognosis is closely related to early diagnosis and treatment. In recent years, with the development of endoscopic diagnosis and treatment technology, especially the breakthrough progress of new endoscopic equipments, the detection rate of early esophageal cancer and precancerous lesions is significantly improved, and more and more patients with early esophageal cancer can be treated with minimally invasive endoscopic treatment. At present, endoscopic dissection has become the preferred treatment for early esophageal cancer and precancerous lesions. The advantages is not only less traumatic than traditional surgery, but also retain the physiological structure of esophagus, achieve accurate postoperative pathology and better postoperative quality of life of patients. However, endoscopic minimally invasive treatment in progress also face new problems to be solved, such as how to deal with multifocal esophageal lesions, how to estimate esophageal lesions infiltration depth and lymph node metastasis risk accurately, how to understand the discrepancy between biopsy and postoperative pathology, how to deal with the positive resection margins as well as intraoperative and postoperative complications, how to manage endoscopic treatment of the special subpopulation of the patients, whether and when additional radical surgery should be provided to the patients with non-curative endoscopic treatment, and so on. Aiming to the above problems and the purpose to improve the prognosis and the quality of life of esophageal cancer patients, this topic includes a series studies to explore standardized treatment scheme and management strategy for postoperative complications in the endoscopic treatment of early esophageal cancer and precancerious lesions.
