Multicenter StudyTherapeutic outcomes in 1000 cases of endoscopic submucosal dissection for early gastric neoplasms: Korean ESD Study Group multicenter study.
The technique of endoscopic submucosal dissection (ESD) was introduced to be able to obtain en bloc specimens of large early GI neoplasms. The drawback of ESD is its technical difficulty, which, consequently, is associated with a higher rate of complication and which requires advanced endoscopic techniques and a long procedure time. ⋯ ESD is an effective and safe therapy in the management of early gastric neoplasms. Endoscopists have to accept the need for advanced endoscopic techniques for performing ESD in the case of large lesions, scar lesions, undifferentiated cancers, or for the lesions in the upper portion of the stomach. Endoscopists require more experience to decrease complications in patients who have a large or recurrent lesion in the upper portion of the stomach; these lesions also take more time to complete the ESD procedure.
