We present a modification of strip biopsy (SB), one of the endoscopic treatment modalities for early gastric cancer. Using a side-viewing endoscope and a special electrocautery snare, we treated 6 patients with early carcinoma of the intestinal type with this modified strip biopsy (MSB). All tumors could be completely resected and 5 patients were not operated on: All 5 remained tumor-free at follow-up of at least one year. These results compared favorably with a historical control group of 17 patients with early gastric cancer treated with conventional strip biopsy. We therefore recommend applying our new method of MSB especially in the intestinal type of early gastric carcinoma; these preliminary data however, need confirmation in larger trials.
