 The number of patients with cancer in the gastric stump(CGS)after gastrectomy for primary gastric cancer(PGC)is steadily increasing due to the improved prognosis for PGC. On the other hand, the number of patients with CGS after benign disease is decreasing as a result of the low frequency of gastrectomies for benign ulcer in recent decades. The patients with CGS after distal gastrectomy for PGC(malignant group, n=111)and for benign disease(benign group, n=100)were reviewed for comparison of the characteristics. The average age was slightly higher in the malignant group than in the benign group. CGS in the malignant group was generally detected at an early stage and after a short interval from previous gastrectomy as compared with CGS in the benign group. Furthermore,CGS in the benign group after Billroth II reconstruction frequently developed near the gastrojejunostomy, whereas CGS in the malignant group commonly developed in the non-anastomotic site regardless of previous reconstruction. Accurate knowledge of the characteristics of CGS in each group, such as the time interval and the tumor site, is helpful for its earlier detection.
