 We investigated one hundred and forty eight cases under the extended indication of endoscopic submucosal dissection for early gastric cancer. The cases were divided into two groups;The cases of group A (134 cases) were completely resected ones, and the cases of group B (14 cases) were incompletely resected ones. The results were as follows:

 (1) There was no significant difference between the two groups in macroscopic type, location and the use of snares.

 (2) The size of lesions of group B were significantly larger than those of group A.

 (3) The number of cases treated with M-scope in group A was significantly greater than that in group B.

 (4) The reasons for incomplete resection were erroneous diagnosis of the extent of intramucosal infiltration, snaring after insufficient dissection, intraoperative bleeding and insufficient pathological evaluation because of degeneration caused by heating.

 In conclusion, to reduce the number of incompletely resected cases, the extent of intramucosal infiltration of each case must be carefully diagnosed, and it is useful to use the M-scope and magnifying endoscopy with acetic acid and the narrow band imaging (NBI) system.
