[Early additional ESD at SMC]
Previous | List | Next
During the past 8 years, we performed 1,400 ESDs for early gastric cancers. The overall rate of positive lateral resection margin was 5 percent. Early additional ESD was done in 16 cases. Curative resection by early additional ESD was possible in all cases except one case. In the additional ESD pathology, residual cancers were found in 10 cases. There was no residual tumor in 3 cases. We thought that early additional ESD is quite useful in selected cases with positive resection margin.
