MEJIA, Ricardo et al. Experience with endoscopic submucosal dissection for the treatment of early neoplasms of the digestive tract. Rev. méd. Chile [online]. 2021, vol.149, n.4, pp.501-507. ISSN 0034-9887.


Endoscopic submucosal dissection (ESD) allows en-bloc resection of early gastro-intestinal neoplasms (EGIN) with healing potential.


To describe the results of patients treated with ESD for EGIN by our team.

Patients and Methods:

Descriptive study of patients with EGIN who underwent ESD with curative intention between January 2008 and March 2020.


One hundred thirty-two ESD were performed in 127 patients. 77% were gastric lesions, 14% colorectal, 8% esophageal and 1% duodenal. En-bloc resection was achieved in 98.4% of ESDs. Eighty eight percent of patients met curative standards. Overall, cancer-specific, and recurrence-free survival were 95%, 100% and 98% respectively.


ESD allows en-bloc resections with curative potential in selected patients, but with a significant reduction in morbidity and mortality and less impact on quality of life. Our results suggest the feasibility to perform ESD in our country with results comparable to those reported in the literature.
