Long-term follow-up after endoscopic submucosal dissection of colorectal lesions in a Spanish cohort.

Introduction: ESD in the colon is an increasingly important technique in Western countries. There are few studies that include long term follow-up.

Aim: to analyze the long term recurrence free survival rate after ESD and to compare recurrence rates according to different variables.

Endoscopic submucosal dissection for gastric epithelial lesions: long-term results in a Spanish cohort.

Introduction: endoscopic submucosal dissection for gastric lesions (ESD-G) is a technique that allows en-bloc resection of early gastric tumors, with a cure rate similar to that of surgery but lower morbidity and mortality rates.

Objective: to assess total survival, disease-free survival and relapse rate during the course of disease in a Spanish cohort of patients undergoing ESD-G.

Material And Methods: this was a prospective observational study of patients undergoing ESD-G from 2008 to 2015, with a follow-up ranging from six to 60 months.
