 Patient 1 : A man in his forties underwent a complete medical checkup, in which screening for gastric carcinoma using a transnasal endoscope revealed a type 2c lesion in the greater curvature of the antrum. A diagnosis of well-differentiated adenocarcinoma was made based on biopsy. ESD(endoscopic submucosal dissection)was performed, and a pathological diagnosis of minute gastric carcinoma[Type 0-IIc, tub 1, 5×5mm, pT1a(M)]was made.

 Patient 2 : A man in his forties underwent a complete medical checkup, in which screening for gastric carcinoma using a transnasal endoscope revealed aIIa+IIc-like lesion in the anterior wall of the angle. A diagnosis of well-differentiated adenocarcinoma was made based on biopsy. ESD was performed, and a pathological diagnosis of minute gastric carcinoma[Type 0-IIc, tub1, 4×3mm, pT1a(M)]was made.

 It is considered that screening for gastric carcinoma using a transnasal endoscope, with a full understanding of its characteristics and careful observation, can detect minute gastric carcinoma, and yield a diagnostic performance equivalent to that of normal endoscopy.
