HISTOLOGICAL STUDY OF THE GASTRIC LINEAL ULCER. (WITH SPECIAL REFERENCE TO SHORTENING OF THE LESSER CAVATURE OF THE STOMACH.)

It was reported that the remarkable deformity (shortening of the lesser cavature) was observed in the stomach with long lineal ulcer but the reason of the deformity was not explained. For the study of this deformity, 62 cases of the gastric lineal ulcer resected in our surgical clinic, were collected and analyzed histologically.
The stomach with short lesser cavature caused by lineal ulcer had narrow histological antrum and long lineal ulcer. On the contrary, the gastric lineal ulcer with normal lesser cavature had normal histological antrum and short lineal ulcer. In the gastric lineal ulcer with remarkable deformity the antrum disappeared. This narrowing and disappearance of the antrum were found in the gastric lineal ulcer with long lineal ulcer or with lineal ulcer accompaning round ulcer on the anal side.
Large round ulcers were often found on the lineal ulcer or anal side of lineal ulcer. Those round ulcers had high percentage of perforation compare with a single round ulcer. The cause of perforation may be short supply of blood from anal side due to the lineal ulcer. The narrowing and disappearance of antrum may occur when large round ulcer on the anal side of lineal ulcer become a scar.
