Gastric adenocarcinoma in the gastric stump after partial gastrectomy

Carcinomas of the gastric stump are divided into two types. In the main group of patients (n = 18), carcinoma developed after resection for benign ulcer disease, and in the second group (n = 4) after resection for early gastric carcinoma. In the first group, the mean age of the patients was 63, and the male-to-female ratio of 17:1. The mean interval between the primary operation and the diagnosis of cancer was 27 years. Biopsies were positive in 16 out of 18 patients. The resectability rate was 72%, resection being performed with curative intent in 50%. Total gastrectomy was performed in 50% of the cases. There were no postoperative deaths. The 5-year survival rate was 33% for all patients and 50% after tumoral resection. Early detection was achieved by means of an endoscopic survey of the gastric stump. A comparison between gastric stump carcinomas and other gastric carcinomas in our series fails to reveal any major differences. Gastric stump carcinoma is not specific. In the second group, the mean age of the patients was 72.5 and the sex ratio 1:1. The mean interval between the two operations was 5 years. The resectability rate was 100%, and all the patients survived with follow-up ranging from 2 to 10 years. The second lesion could be considered a metachronous cancer, but it may have been present and overlooked at the time of the initial gastrectomy. Differentiating between synchronous and metachronous lesions is quite difficult.
