 Diagnosis of depth invasion is more difficult in type Ⅱc early gastric cancer with converging mucosal folds than without converging mucosal folds. Furthermore, the accuracy of such diagnosis in cases with converging folds is influenced by the degree of stiffness of the gastric wall as well.

 Authors subdivided type Ⅱc gastric cancer with converging mucosal folds into four types based on the degree of stiffness of the gastric wall. The results were as follows:  (1) In cases with diffuse stiffness involving entire lesion, diagnosis of depth invasion was impossible.

 (2) Among cases with partial stiffness, stiffness involving larger area indicated sm or pm.

 (3) In cases with localized stiffness due to scarring, depth invasion proved to be m or sm with small invasion.

 (4) In cases with mass in the lesion, which implies mass formation in the submucosa, depth invasion was either sm or pm.
