RESUMEN
Objective To analyze the characteristic of endoscopic submucosal dissection (ESD) in elderly patients aged more than or equal to 80 years. Methods We retrospectively reviewed 41 patients aged more than or equal to 80 years with 47 lesions treated by ESD from September 2010 to January 2017. The diseased region, pathology and complications were evaluated. Results Of the 47 lesions, there have 3 esophageal lesions, 21 gastric lesions, 10 colonic lesions and 13 rectal lesions. For the pathology, there have 34 early cancer or precancerous lesion, 2 GIST, 1 neuroendocrine tumor and 10 other types of pathology. 1 cardia1 early cancer underwent additional laparoscopic lymphadenectomy. There have 7 complications, 4 post-ESD bleeding, 2 delirium and 1 pneumonia. Conclusion ESD for colorectal lesion is more frequently in elderly patients aged more than or equal to 80 years. Post-ESD bleeding is the main complication.
