[Differential diagnosis and surgical treatment of colorectal nonepithelial tumors]

An analysis of results of the examination and treatment of 92 patients with nonepithelial colorectal tumors has shown that the correct diagnosis can be made in 82% of the cases on the basis of using complex X-ray, ultrasonic and endoscopic methods. Of decisive significance in determination of the tumor tissue character is the morphological investigation. Extensive surgical interventions were performed due to suspected malignization on 21 patients with benign nonepithelial tumors. In other cases (n = 49) the organ-saving operations were fulfilled. The decision between the volumes of the surgery for malignant nonepithelial tumors (n = 24) was not difficult in most cases and depended on the spread of the oncological process. The 5-year survival in this group of patients was 57%. No recurrences were noted after ablation of benign tumors.
