Aim of study: Comparative assessment outcomes of endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) in patients with superficial epithelial lesions (SEL) of stomach and duodenum.
Materials and methods: Retrospective study includes 92 patients. The article contains detailed description of patients, superficial epithelial lesions, technique of EMR and ESD and indications for endoscopic procedure.
Results: 99 endoscopic operations were performed: EMR--79, ESD--20. The mean operation time, en bloc resection rate, complete resection rate for early gastric cancer were assessed for EMR and ESD and compared in consideration of lesion's size. Comparative evaluation of immediate, short-term and long-term outcomes of endoscopic resections was performed.
Conclusion: ESD provides better en bloc and complete resection rates and minimal local recurrence compared with EMR, but ESD is more time-consuming technique with the same rate of complications.
