With the improvement of endoscopic diagnosis, the discovery rate of the synchronous multiple primary early cancers in esophagus and stomach is gradually increased, while the traditional surgery bringing serious damages. Endoscopic submucosal dissection (ESD) has become the first treatment option of early cancer in the digestive tract partly. This study intends to explore the feasibility, safety, and effectiveness of ESD in the treatment of the synchronous multiple early gastric cancer or precancerous lesions in the esophagus and stomach.


From January 2008 to December 2016, data of 12 patients with early esophageal cancer and early gastric cancer treated by ESD in the Endoscopy Center of Zhongshan Hospital, Fudan University were reviewed. We analyzed the patient's history, the size of esophageal and gastric lesions, pathological results, the results of complete or curative resection, and so on.


Among the 12 patients described in this study, all were diagnosed with synchronous multiple primary early cancers in the esophagus and stomach. Lesions were removed by ESD in 10 cases at the same time and were removed by stage in 2 cases. The complete resection rate was 100% (24/24), and the curative resection rate was 100% (24/24). Postoperative esophageal stricture occurred in 2 cases, which improved after dilation. Median follow-up time was 30 (8-115) months, when 9 patients survived and 3 patients died. However, the cause of death was not associated with treatment of this disease.


ESD is a minimally invasive endoscopic surgery, which can be used as a method of treating synchronous multiple primary early cancers in the esophagus and stomach.
