[The surgical treatment of malignant stomach ulcers].

The authors analyse the specific features of the clinical picture, diagnosis, pathomorphological changes and surgical treatment in 52 patients with gastric ulcer which underwent malignant degeneration. It is noted that malignancy occurs most frequently in close vicinity to the ulcerative defect and rarely in the mucosa beyond the ulcer. The morphostructural reorganizations are determined to a certain degree by the peculiarities of extension of the tumor along the mucosa and the organ as a whole. The authors discuss the principles of the choice of the method for treatment according to the findings of pathomorphological examination of biopsy material and the results of emergency intraoperative examination. Even if the merest suspicion of malignancy of the ulcer arises, the operation should be conducted with observance of all oncological principles. Postoperative mortality was 3.8%, complications occurred in 7.7% of cases. Five-year survival was 84.6% in the absence of metastases and the presence of carcinoma cells within the limits of the mucosa and 12.5% among cases in which metastases were found during the operation. Attention is drawn to the principles of regular medical surveillance over patients receiving nonoperative treatment for gastric ulcer.
