Endoscopic Aspiration Mucosectomy of Gastric Adenoma and Early Gastric Cancer: Two Year Experience with Assessment of Results

  • 1Department of Internal Medicine, College of Medicine, The Catholic University of Korea, Seoul, Korea.


Endoscopic aspiration mucosectomy (EAM) can always lift up the lesion by suction regardless of its location and does not injure the mucosal surface. The clinical usefulness of this method was evaluated as follows.
Thirty two patients with gastric adenoma (35 lesions) and 6 patients with early gastric carcinoma were treated by EAM from March 1997 to February 1999. Their characteristics (diameter, macroscopic appearance, and histologic diagnosis) were verified at endoscopy with a biopsy specimen. The complete resection was defined as the presence of normal mucosa at the resected margin.
The average size of the resected specimens was 17.8 mm in antrum and 16.5 mm in body. The ratio of complete resection by location was 67% in anterior wall, 88% in posterior wall, 86% in lesser curvature and 92% in greater curvature. The complete resection rate for smaller lesions (< or =15 mm) was highly distinguished from that of larger lesions (>15 mm). No serious complication was encountered.
EAM is suitable for the treatment of gastric tumors. Lesions 15 mm or less in diameter can be resected easily by single procedure regardless of its location.
