[Clinical and pathological characteristics of gastric stump cancer and recurrent gastric stump cancer].

OBJECTIVE

To study early diagnosis and rational treatment of gastric stump cancer and recurrent gastric stump cancer.

METHODS

The data of 27 patients with gastric stump cancer and 23 patients with recurrent gastric stump cancer were analysed retrospectively during the past 20 years based on their clinical and pathological findings.

RESULTS

The onset time was 10 years or more for gastric stump cancer and less than 10 years for recurrent gastric stump cancer after gastrectomy. Gastroscopy was better than double contrast radiography in diagnosis. Partial resection of gastric stump was performed for patients with early cancer at the anastomotic stoma of gastrojejunostomy. Total resection of gastric stump was made for other patients. Lymph node of the mesojejunum were dissected routinely because their metastasis rate was about 40.0% in patients with cancer of anastomotic stoma. The effect of surgical treatment was poor for patients with advanced cancer.

CONCLUSIONS

Regular gastroscopy is useful in detecting gastric stump cancer in patients with gastric cancer after gastrectomy, or in those years after removal benign. Malignancy was more evident in recurrent gastric stump cancer than in primary gastric cancer. Prognosis is good for early stage cases and poor for late stage cases after surgical treatment.
