The use of sodium fluorescein staining of peripheral lymph vessels provides a clear fluorescent image faithful to the location of the lymph vessels, which is confirmed by experiments on rabbits. Contrast lymphatic vessels with fluorescent paint allows visualizing them in 100% of cases. This can be used as prophylaxis in lymphorrhea operated patients, although with increasing age of patients undergoing radical surgery for malignant tumors, gradually decreases as the total amount of postoperative lymphorrhea and lymphorrhea per night.

When penetration of gastric ulcers of the stomach wall is destroyed along with the lymphatic network in the area of the ulcer. Lymphotropic opacification of the lymph vessels of the stomach wall were used for the diagnosis of penetrating ulcers. Studies of morpho-functional state of the stomach in patients with different localization of ulcer process demonstrated their importance in predicting the flow of gastric ulcers. Studies indicators changes of the lymphatic system and the morphological and functional state of the stomach in patients with different localization of ulcer process demonstrated their importance in predicting the flow of gastric ulcers. The proposed system of forecast evaluation of the severity of the patient reveals the risk of disease with complicated peptic ulcer disease to justify the treatment method, indications for surgery and to predict the outcome of treatment.

Authors present a review of modern approach to surgical treatment of gastric cancer. They discussed a various contemporary issues: epidemiology, classification, different methods of reconstruction following total gastrectomy, the estimate of quality of life after radical operations. In conclusion, the further study is required to optimize the multimodal approach of locally advanced gastric cancer and integration with additional conservative methods such as systemic therapy.
