2. Figure 1
A general outline of the differences in management of lateral spreading tumors with piecemeal (endoscopic mucosal resection) versus en bloc resection, whether performed by endoscopic submucosal dissection (ESD) or by EMR. Actual decisions can depend on other factors not depicted here, including patient life expectancy and comorbidities, patient preferences, and pathologic factors such as degree of differentiation, lymphatic invasion, and tumor budding.
