As a long-term follow up study, a total 2613 patients who had undergone partial gastric resection for benign gastroduodenal diseases between 1960 and 1964 were examined. The incidence of gastric stump carcinoma in 756 patients alive more than 20 years after gastroduodenostomy and in 299 patients after gastrojejunostomy was determined. Cancer was observd in two patients after gastroduodenostomy and in four after gastrojejunostomy. The incidence of cancer (0.539/1000 population) in male patients who had undergone gastrojejunostomy when they were less than 40 years old was four times higher than after gastroduodenostomy. Twenty-eight cancers in the gastric remnant after partial gastrectomy for benign disease were studied. Significantly more cacers (13/18) developed at the anastomotic site by gastrojejunostomy than by gastroduodenostomy (3/10) (p<0.05). Histologically well-differentiated cancer was found in gastritis cystica polypose of the gastrojejunostomy more than 20 years earlier have a higher risk of cancer at the site of anastomosis than the patients who had a gastroduodenostomy.
