Title: Improved Curative Resection Rates of Early Gastric Cancers By Endoscopic Mucosal Resection (EMR) Using Endoscopic Submucosal Dissection Method (ESD)
Abstract: Background: EMR is now accepted as one of the standard treatment for early gastric cancers with low probability of lymph node metastasis. Although, the basic EMR techniques are strip biopsy method and cap method, the chance of local recurrence after EMR remains problem if the resection margin is not clear. Because the benefit of EMR can be achieved only through careful histologic examination, an en-block resection is recommended. Aims: In order to resect mucosal cancers perfectly, endoscoipc submucosal dissection EMR (ESD) using insulation tipped diathermic knife (IT knife) and hook knife was performed for early gastric cancers in the last 4 years in our hospital. Method: EMR was applied to patients with early gastric cancers up to 20 mm in diameter that were of a well or moderately histologically differentiated type, and superficially elevated and/or depressed type (type I, IIa, and IIc) without ulceration. Results: Eighty patients were treated by basic EMR procedure from 1994 to 2004. The rate of EA resection (which means curative resection) was 51.3% (41/80), and additional operations were performed in 8 patients (10%). Since ESD procedure was used, 57 patients were treated with ESD. The rate of EA resection was 75.4% (43/57), and additional operations were performed in 6 patients (9%) because of depth of the tumors. There were no gastric cancer related deaths during follow up period. Conclusion: EMR treatment for early gastric cancer by submucosal dissection (ESD) method using IT knife and hook knife is feasible and effective technique.
