Early carcinoma of the stomach after gastric surgery: comparison with early carcinoma in the non-operated stomach.
The relationships between the gross and histological types of early gastric carcinoma and non tumorous gastric mucosa were investigated in 12 cases of carcinoma of the stomach after operation and 46 cases of cardiac carcinoma within 5 cm of the squamocolumnar junction. Histological studies were made by examining specimens obtained by gastrectomy. Grossly elevated and histologically differentiated carcinomas were statistically more frequent after gastric surgery, than before. Comparison between cases of elevated and differentiated adenocarcinoma that had undergone gastric surgery with those that had not showed that atrophic gastritis and intestinal metaplasia in the surrounding mucosa of the tumor were significantly slighter after gastric operation than in unoperated cases. Results suggested that early carcinomas developing after gastric surgery are different from those in the upper portion of the unoperated stomach.
