Usefulness of endoscopic aspiration mucosectomy as compared with strip biopsy for the treatment of gastric mucosal cancer☆,☆☆
Section snippets
PATIENTS AND METHODS
We compared the results of strip biopsy in 44 consecutive patients who underwent the procedure between May 1995 and February 1996 with the results in 49 consecutive patients who underwent EAM between March 1996 and May 1997. Patients with intestinal-type intramucosal cancer of the stomach were eligible for enrollment.
EAM was performed as described by Torii et al.5 Briefly, the lesion margin was marked with a heater probe (Olympus Optical Co., Ltd., Tokyo, Japan). Physiologic saline solution was

The demographic characteristics of the two groups of patients are shown in Table 1.

DISCUSSION
Endoscopic mucosal resection (EMR) is becoming a widely accepted treatment of early gastric cancer. Endoscopic treatment is now considered a viable option in GI oncology, and its therapeutic efficacy, including benefits with respect to patients’ quality of life, is being evaluated by many centers. Various techniques are used to perform EMR,1, 2, 3, 4 strip biopsy being the most widely used. Strip biopsy is considered useful for diagnosis as well as treatment.1, 7 We have used strip biopsy since
